IMPAIRED HEALTH-RELATED QUALITY OF LIFE IN PATIENTS WITH IDIOPATHIC INFLAMMATORY MYOPATHIES: A CROSS-SECTIONAL ANALYSIS FROM AN INTERNATIONAL E-SURVEY

BackgroundComprehensive and large-scale assessment of health-related quality of life in patients with idiopathic inflammatory myopathies (IIMs) worldwide is lacking. The second COVID-19 vaccination in autoimmune disease (COVAD-2) study [1] is an international, multicentre, self-reported e-survey assessing several aspects of COVID-19 infection and vaccination as well as validated patient-reported outcome measures (PROMs) to outline patient experience in various autoimmune diseases (AIDs), with a particular focus on IIMs.ObjectivesTo investigate physical and mental health in a global cohort of IIM patients compared to those with non-IIM autoimmune inflammatory rheumatic diseases (AIRDs), non-rheumatic AIDs (NRAIDs), and those without AIDs (controls), using Patient-Reported Outcome Measurement Information System (PROMIS) global health data obtained from the COVAD-2 survey.MethodsDemographics, AID diagnoses, comorbidities, disease activity, treatments, and PROMs were extracted from the COVAD-2 database. The primary outcomes were PROMIS Global Physical Health (GPH) and Global Mental Health (GMH) scores. Secondary outcomes included PROMIS physical function short form-10a (PROMIS PF-10a), pain visual analogue scale (VAS), and PROMIS Fatigue-4a scores. Each outcome was compared between IIMs, non-IIM AIRDs, NRAIDs, and controls. Factors affecting GPH and GMH scores in IIMs were identified using multivariable regression analysis.ResultsA total of 10,502 complete responses from 1582 IIMs, 4700 non-IIM AIRDs, 545 NRAIDs, and 3675 controls, which accrued as of May 2022, were analysed. Patients with IIMs were older [59±14 (IIMs) vs. 48±14 (non-IIM AIRDs) vs. 45±14 (NRAIDs) vs. 40±14 (controls) years, p<0.001] and more likely to be Caucasian [82.7% (IIMs) vs. 53.2% (non-IIM AIRDs) vs. 62.4% (NRAIDs) vs. 34.5% (controls), p<0.001]. Among IIMs, dermatomyositis (DM) and juvenile DM were the most common (31.4%), followed by inclusion body myositis (IBM) (24.9%). Patients with IIMs were more likely to have comorbidities [68.1% (IIMs) vs. 45.7% (non-IIM AIRDs) vs. 45.1% (NRAIDs) vs. 26.3% (controls), p<0.001] including mental disorders [33.4% (IIMs) vs. 28.2% (non-IIM AIRDs) vs. 28.4% (NRAIDs) vs. 17.9% (controls), p<0.001].GPH median scores were lower in IIMs compared to NRAIDs or controls [13 (interquartile range 10–15) IIMs vs. 13 (11–15) non-IIM AIRDs vs. 15 (13–17) NRAIDs vs. 17 (15–18) controls, p<0.001] and PROMIS PF-10a median scores were the lowest in IIMs [34 (25–43) IIMs vs. 40 (34–46) non-IIM AIRDs vs. 47 (40–50) NRAIDs vs. 49 (45–50) controls, p<0.001]. GMH median scores were lower in AIDs including IIMs compared to controls [13 (10–15) IIMs vs. 13 (10–15) non-IIM AIRDs vs. 13 (11–16) NRAIDs vs. 15 (13–17) controls, p<0.001]. Pain VAS median scores were higher in AIDs compared to controls [3 (1–5) IIMs vs. 4 (2–6) non-IIM AIRDs vs. 2 (0–4) NRAIDs vs. 0 (0–2) controls, p<0.001]. Of note, PROMIS Fatigue-4a median scores were the highest in IIMs [11 (8–14) IIMs vs. 8 (10–14) non-IIM AIRDs vs. 9 (7–13) NRAIDs vs. 7 (4–10) controls, p<0.001].Multivariable regression analysis in IIMs identified older age, male sex, IBM, comorbidities including hypertension and diabetes, active disease, glucocorticoid use, increased pain and fatigue as the independent factors for lower GPH scores, whereas coexistence of interstitial lung disease, mental disorders including anxiety disorder and depression, active disease, increased pain and fatigue were the independent factors for lower GMH scores.ConclusionBoth physical and mental health are significantly impaired in patients with IIMs compared to those with non-IIM AIDs or those without AIDs. Our results call for greater attention to patient-reported experience and comorbidities including mental disorders to provide targeted approaches and optimise global well-being in patients with IIMs.Reference[1]Fazal ZZ, Sen P, Joshi M, et al.

REDUCED HEALTH-RELATED QUALITY OF LIFE USING PROMIS IN PATIENTS WITH SYSTEMIC SCLEROSIS: A CROSS-SECTIONAL ANALYSIS FROM THE INTERNATIONAL COVAD-2 E-SURVEY

BackgroundThe second COVID-19 vaccination in autoimmune disease (COVAD-2) study [1] is an international, multicentre, self-reported e-survey designed to evaluate several facets covering COVID-19 infection and vaccination as well as validated patient-reported outcome measures (PROMs) in a variety of autoimmune diseases (AIDs), including systemic sclerosis (SSc). Detailed assessment of the health-related quality of life (HRQOL) and its drivers in patients with SSc is lacking.ObjectivesTo assess physical and mental health in a global cohort of SSc patients in comparison with non-SSc autoimmune inflammatory rheumatic diseases (AIRDs), non-rheumatic AIDs (NRAIDs), and those without AIDs (controls) using Patient-Reported Outcome Measurement Information System (PROMIS) global health data from the COVAD-2 survey.MethodsThe COVAD-2 database was used to extract demographics, AID diagnosis, comorbidities, disease activity, current therapies, and PROMs. PROMIS global physical health (GPH), global mental health (GMH) scores, PROMIS physical function short form-10a (PROMIS PF-10a), pain visual analogue scale (VAS), and PROMIS Fatigue-4a scores were compared between SSc, non-SSc AIRDs, NRAIDs, and controls. Outcomes were also compared between diffuse cutaneous SSc (dcSSc) vs limited cutaneous SSc (lcSSc). Multivariable regression analysis was performed to identify factors influencing GPH and GMH scores in SSc.ResultsA total of 10,502 complete responses from 276 SSc, 6006 non-SSc AIRDs, 545 NRAIDs, and 3675 controls as of May 2022 were included in the analysis. Respondents with SSc were older [SSc vs. non-SSc AIRDs vs. NRAIDs vs. controls: 55 (14) vs. 51 (15) vs. 45 (14) vs. 40 (14) years old, mean (SD), p < 0.001]. Among patients with SSc, 129 (47%) had dcSSc and 147 (53%) had lcSSc. SSc patients reported a significantly higher prevalence of ILD [SSc vs. non-SSc AIRDs vs. NRAIDs vs. controls: 30.4% vs. 5.5% vs. 1.5% vs. 0.2%, p < 0.001], and treatment with MMF [SSc vs. non-SSc AIRDs vs. NRAIDs vs. controls: 26.4% vs. 9.5% vs. 1.1% vs. 0%, p < 0.001].Patients with SSc had lower GPH and PROMIS PF-10a scores [SSc vs. non-SSc AIRDs vs. NRAIDs vs. controls: 13 (11–15) vs. 13 (11–15) vs. 15 (13–17) vs. 17 (15–18), median (IQR), p < 0.001;39 (33–46) vs. 39 (32–45) vs. 47 (40–50) vs. 49 (45–50), p < 0.001, respectively] and higher Pain VAS and PROMIS Fatigue-4a scores compared to those with NRAIDs or controls [SSc vs. non-SSc AIRDs vs. NRAIDs vs. controls: 3 (2–5) vs. 3 (1–6) vs. 2 (0–4) vs. 0 (0–2), p < 0.001;11 (8–14) vs. 11 (8–14) vs. 9 (7–13) vs. 7 (4–10), p < 0.001, respectively]. Patients with AIDs including SSc had lower GMH scores compared to controls [SSc vs. non-SSc AIRDs vs. NRAIDs vs. controls: 12.5 (10–15) vs. 13 (10–15) vs. 13 (11–16) vs. 15 (13–17), p < 0.001].Among SSc patients, GPH, GMH, and PROMIS PF-10a scores were lower in dcSSc compared to lcSSc [dcSSc vs. lcSSc: 12 (10–14) vs. 14 (11–15), p < 0.001;12 (10-14) vs. 13 (10-15), p<0.001;38 (30–43) vs. 41 (34–47), p < 0.001, respectively]. Pain VAS and PROMIS Fatigue-4a scores were higher in dcSSc compared to lcSSc [4 (2–6) vs. 3 (1–5), p < 0.001;12 (8–15) vs. 9 (8–13), p < 0.001, respectively].The independent factors for lower GPH scores in SSc were older age, Asian ethnicity, glucocorticoid use, and higher pain and fatigue scales, while mental health disorders and higher pain and fatigue scales were independently associated with lower GMH scores.ConclusionIn a global cohort, patient-reported physical and mental health were significantly worse in patients with SSc in comparison to those with non-SSc AIDs and without AIDs. Our findings support the critical need for more attention to patient's subjective experiences including pain and fatigue to improve the HRQOL in patients with SSc.Reference[1]Fazal ZZ, Sen P, Joshi M, et al.

POSSIBLE ROLE OF PEPTIDE EPITOPES OF COVID-19 BNT-162B2 MRNA VACCINE IN FOMENTING AUTOIMMUNITY: AN IN SILICO ANALYSIS

BackgroundFollowing the launch of the global COVID-19 vaccination campaign, there have been increased reports of autoimmune diseases developing de novo following vaccination. These cases include rheumatoid arthritis, autoimmune hepatitis, immune thrombotic thrombocytopenia, and connective tissue diseases. Nevertheless, COVID-19 vaccines are considered safe for patients with autoimmune diseases and are strongly recommended.ObjectivesThe aim of this in silico analysis is to investigate the presence of protein epitopes encoded by the BNT-162b2 mRNA vaccine, one of the most commonly administered COVID-19 vaccines, that could elicit an aberrant adaptive immune response in predisposed individuals.MethodsThe FASTA sequence of the protein encoded by the BNT-162b2 vaccine was retrieved from http://genome.ucsc.edu and used as a key input to the Immune Epitope Database and Analysis Resource (www.iedb.org). Linear peptides with 90% BLAST homology were selected, and T-cell, B-cell, and MHC ligand assays without MHC restriction were searched and evaluated. HLA-disease associations were screened on the HLA-SPREAD platform (https://hla-spread.igib.res.in) by selecting only positive markers.ResultsA total of 183 epitopes were found, corresponding to 178 SARS-CoV-2 and 5 SARS-CoV spike epitopes, respectively. Results were obtained from 22 T-cell assays, 398 B-cell assays, and 2 MHC ligand assays. Complementary receptors included 1080 T-cell receptors and 0 B-cell receptors.Specifically, the IEDB_epitope:1329790 (NATNVVIKVCEFQFCNDPFLGVYY) was shown to bind to HLA-DRB1*15:02 and HLA-DRB1*15:03 alleles, whereas the IEDB_epitope:1392457 (TKCTLKSFTVEKGIYQTSNFRVQPT) was reported to bind to HLA-DRB1*07:01, HLA-DRB1*03:01, HLA-DRB3*01:01, and HLA-DRB4*01:01 alleles. The HLA alleles detected were found to be positively associated with various immunological disorders (Table 1).Table 1.MHC-restricted epitopes of the BNT-162b2 vaccine and potentially associated immunological conditionsEpitopeAssayMHC moleculeAssociated disease (population)NATNVVIKVCEFQFCNDPFLGVYY + OX(C10)cellular MHC/mass spectrometry ligand presentationHLA-DRB1*15:02Takayasu arteritis (Japanese) Arthritis (Taiwanese) Scleroderma (Japanese) Colitis (Japanese)HLA-DRB1*15:03Systemic lupus erythematosus (Mexican American)TKCTLKSFTVEKGIYQTSNFRVQPT + SCM(K2)as aboveHLA-DRB1*07:01Allergy, hypersensitivity (Caucasian)HLA-DRB1*03:01Type 1 diabetes (African) Sarcoidosis, good prognosis (Finnish)HLA-DRB3*01:01Graves' disease (Caucasian) Thymoma (Caucasian) Sarcoidosis (Scandinavian) Autoimmune hepatitis (Caucasian)HLA-DRB4*01:01Vitiligo (Saudi Arabian)ConclusionSimilar to the SARS-CoV-2 spike protein, the protein product of the BNT-162b2 mRNA vaccine contains immunogenic epitopes that may trigger autoimmune phenomena in predisposed individuals. Genotyping for HLA alleles may help identify at-risk individuals. However, further research is needed to elucidate the underlying mechanisms and potential clinical implications.References[1]Vita R, Mahajan S, Overton JA et al.

EFFICACY AND SAFETY OF DAZODALIBEP (VIB4920/HZN4920) IN SUBJECTS WITH SJÖGREN'S SYNDROME: A PHASE 2, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, PROOF OF CONCEPT STUDY

BackgroundSjögren's syndrome (SS) is a chronic, systemic autoimmune disease affecting exocrine glands, primarily the salivary and tear glands, with potentially severe manifestations in multiple organs. No approved disease-modifying therapies exist. Dazodalibep (DAZ) is a biologic antagonist of CD40L.ObjectivesThe objective of this study was to evaluate the efficacy and safety of DAZ therapy in adult SS subjects with moderate-to-high systemic disease activity (NCT04129164).MethodsWe conducted a randomized, double-blind, placebo-controlled, crossover study to evaluate DAZ therapy in adult SS subjects with moderate-to-high systemic disease activity, as defined by a EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) score ≥ 5. Eligible subjects were randomized 1:1 to receive intravenous DAZ 1500 mg or placebo (PBO) Q2W x 3 doses, then Q4W x 4 additional doses. Starting on Day 169, subjects initially randomized to DAZ received PBO Q4W x 5 doses and subjects randomized to PBO received DAZ Q4W x 5 doses and were then followed for 12 weeks. The primary endpoint was the change from Baseline in ESSDAI at Day 169. Safety assessments included the incidence of adverse (AEs), serious AEs (SAEs), and AEs of special interest (AESIs).ResultsThe 74 randomized subjects all received ≥1 dose of study medication (DAZ, N=36;PBO, N=38). The baseline demographics and disease characteristics were balanced between the two groups. The change from Baseline to Day 169 in ESSDAI score (LS mean ± SE), was -6.3 ± 0.6 in DAZ-treated subjects compared to -4.1 ± 0.6 in the PBO group, a difference of -2.2 (p = 0.0167). Compared to the PBO group, the DAZ group showed positive trends in the EULAR Sjögren's Syndrome Patient Reported Index score, and Functional Assessment of Chronic Illness Therapy-Fatigue score at Day 169. A post-hoc responder analysis of subjects achieving high levels (5 and 6 points) of improvement on ESSDAI favored DAZ (61.1% and 60.0%) over PBO (35.1% and 34.3%).The reported AEs were generally mild through Day 169 and similar in frequency between treatment groups. The most frequently reported AEs occurring in ≥5% of DAZ-treated subjects and >PBO were COVID-19, diarrhea, dizziness, ligament sprain, upper respiratory tract infection, contusion, device allergy, fatigue, hypertension, and oropharyngeal pain. Two SAEs were reported in a single DAZ-treated subject: this subject was a 59-year-old female who experienced a grade 3 SAE of COVID-19 infection and later died of unknown cause 46 days after last administration of DAZ (12 days after COVID-19 diagnosis). There was a single AESI of herpes zoster in a DAZ-treated subject.ConclusionDAZ is a potential new therapy for the treatment of systemic disease activity in patients with SS. SS subjects with moderate-to-high systemic disease receiving DAZ experienced a statistically significant reduction in disease activity relative to PBO as measured by the improvement in ESSDAI score. Except for a case of severe COVID-19 infection, DAZ therapy in SS subjects appeared to be well tolerated. Larger controlled trials of DAZ therapy for SS are warranted to further explore its safety profile and confirm its clinical efficacy.Table 1.Efficacy and Safety DataPBO N=38DAZ 1500 mg N=36EfficacyΔESSDAI, LS mean (SE) †-4.1 (0.6)-6.3 (0.6)*ΔESSPRI, LS mean (SE) †-1.12 (0.29)-1.80 (0.31)ΔFACIT-Fatigue, LS mean (SE) †5.8 (1.6)8.1 (1.6)AE Summary, n (%)≥1 AE23 (60.5)28 (77.8)≥1 related AE8 (21)10 (27.8)≥1 SAE01 (2.8)≥1 related SAE00≥1 AE leading to discontinuation00≥1 AESI01 (2.8)≥1 Death01 (2.8)Efficacy endpoints as of Day 169;† Analyzed using MMRM;Comparisons vs PBO;*p<0.05;AE summaries based on AEs that occurred through Day 169;AE, adverse event;AESI, adverse event of special interest;ESSDAI, EULAR Sjögren's Syndrome Disease Activity Index;ESSPRI, EULAR Sjögren's Syndrome Patient Reported Index;FACIT-Fatigue, Functional Assessment of Chronic Illness Therapy-Fatigue;PBO, placebo;SAE, serious adverse eventFigure 1.AcknowledgementsFunded by Horizon herapeutics.

PROSPECTIVE EVALUATION OF THE EFFECT OF THE VACCINE AGAINST SARS-COV-2 IN PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS: DATA FROM SAFER STUDY

BackgroundSystemic lupus erythematosus (SLE) is an autoimmune disease, which presents an immune disorder that leads to the production of autoantibodies with potential involvement of multiple organs. Infections are one of the most frequent causes of hospitalization and death in lupus patients, and SARS-CoV-2 infection has been a global threat since March 2020. Immunization of these patients has been strongly recommended, although vaccine evaluation studies have not included this profile of patients.ObjectivesTo evaluate the immunogenicity and safety after 2 doses of the vaccine against SARS-CoV2 in patients with SLE.MethodsSubgroup of SLE patients from the prospective multicenter cohort of patients with immune-mediated diseases "SAFER” – Safety and Efficacy on COVID-19 Vaccine in Rheumatic Disease, a phase IV study. Vaccination against SARS-CoV-2 took place with vaccines approved by Brazilian regulatory bodies CoronaVac (Inactivated SARS-CoV-2 Vaccine), ChadOx-1 (AstraZeneca) and BNT162b2 (Pfizer-BioNTech) and this project followed in line with the guidelines of the National Immunization Plan in Brazil. Patients aged 18 years or older with a previous diagnosis of SLE (according to the 2019 ACR/EULAR criteria) were included. Patients were evaluated by telephone contact and in a face-to-face visit on the 28th day after each dose. Patients were followed up by means of blood collection for measurement of IgG antibody against SARS-COV-2 by chemiluminescence and disease activity assessed using SLEDAI-2K score.ResultsA total of 367 individuals with SLE were included, of whom 207 received 2 doses of CoronaVac, 128 received 2 doses of ChadOx-1 and 32 received 2 doses of BNT162b2. 90% of the subjects were female with a mean age of 37 years. About 42% (154) of the individuals included did not have any other associated comorbidity. 50% (182) of patients were using oral glucocorticoids and azathioprine was the most frequent immunosuppressive therapy. Regarding disease activity parameters, 38% (140) of patients had zero SLEDAI-2K at baseline and 41% (147) had zero SLEDAI-2K 28 days after the 2nd dose. Anti-DNA positivity was 30.7% (16/52) at inclusion and 32.6% (17/52) 28 days after the 2nd dose. Complement consumption was present in 18% (10/55) at inclusion and in 14.5% (8/55) 28 days after the 2nd vaccine dose. The geometric mean titers of IgG antibodies against SARS-COV-2 increased in the different vaccine groups, log 2.27 BAU/mL at inclusion and log 5.58 BAU/mL 28 days after the 2nd dose. Antibody titers after second dose varied between different vaccines, 4.96 BAU/mL CoronaVac, 6.00 BAU/mL ChadOx-1 and 7.31 BAU/mL BNT162b2 vaccine, p < 0.001. Only 3.54% (13/367) patients had covid-19 infection after the 15th day of the second dose of immunization, 9 of them having received 2 doses of CoronaVac, 4 of them of ChadOx-1 and none of them receiving BNT162b2, with p-value of 0.63.ConclusionThis study suggests that vaccines against SARS-COV-2 are safe in SLE patients. Induction of immunogenicity occurred in different vaccine regimens. Only 3.5% of individuals had COVID-19 infection with no difference between the types of vaccines evaluated. Future analyzes to explore the association of the effect of immunosuppressive medication, as well as the impact of booster doses and longer follow-up on clinical outcome will be performed.References[1]Mason A, et al.

CLINICAL AND IMMUNOLOGICAL PROFILES OF PATIENTS WITH ANTI-SYNTHETASE SYNDROME: A RETROSPECTIVE COHORT STUDY FROM A TERTIARY CENTRE

BackgroundAnti-synthetase syndrome (ASS) is a rare auto-immune condition that combines autoantibodies and specifics clinical manifestations, including myositis, interstitial lung disease (ILD), polyarthritis, mechanic's hands, Raynaud's phenomenon, and unexplained fever. The hallmark of this syndrome is the presence of anti-aminoacyl-tRNA-synthetase (ARS) antibodies. Several anti-ARS antibodies have been described, anti-Jo1 being the most common, followed by anti-PL7, anti-PL12, anti-OJ, anti-EJ, anti-KS, anti-YRS, and anti-Zo. According to a recent epidemiological survey, the rising number of patients with autoimmune diseases, including idiopathic inflammatory myopathies (IIM) coincides with the COVID-19 pandemic.ObjectivesTo evaluate the clinical characteristics of ASS patients with different anti-ARS antibodies from a tertiary rheumatology center.MethodsWe conducted a retrospective, single-centered study on consecutive patients diagnosed with ASS from 1 January 2015 to 31 December 2022. Clinical and serologic data were obtained by medical records review from hospital database. Myositis-specific antibodies (MSA) and myositis-associated antibodies (MAA) were tested using commercial ELISA kits. We included all patients fulfilling Connor's criteria for ASS.ResultsSixty-one patients (44 females) with mean age 54.4 (13.8) years were included. The most frequently reported clinical manifestation was arthralgia (68.8%), followed by Raynaud's phenomenon (67.2%), ILD (65.6%), myositis (46%), mechanic's hands (44.3%), arthritis (39.3%), and fever (18.0%). The typical triad for ASS, including myositis, arthritis and ILD was present in 17 patients. Twenty-eight (45.9%) patients were PL7+, 21 (34.4%) were Jo1+, 3 (4.9%) were PL12+, and 2 (3.2%) were OJ+. Seven patients were positive for more than two anti-ARS antibodies. The most frequently found MAA was anti-Ro52 (n=23, 37.7%). Of the 61 patients included, 41 (67.2%) patients were diagnosed in the last 3 years (COVID-19 pandemic). The most frequently detected MSA in ASS patients diagnosed during COVID-19 pandemic was anti-PL7 (25/28), while anti-Jo1 was the most common MSA in ASS patients diagnosed before 2020 (p<0.05) (Fig 1).The anti-Jo1+ patients were younger, have significantly more frequent muscle involvement and significantly higher levels of CK than anti-PL7+ patients (p<0.05). The co-occurance of anti-Ro52 antibodies was more frequently observed in anti-Jo1+ patients (n=11, 52.4%) than in anti-PL7+ patients (n=6, 21.4%) (p<0.05). We did not find statistically significant differences between ASS groups regarding sex, disease duration, clinical manifestations including dermatologic lesions, Raynaud's phenomenon, arthralgia/arthritis, ILD, fever, and cancers (all p>0.05).ConclusionASS patients have heterogenous manifestations, and different types of anti-ARS antibodies are associated to distinct clinical and immunological features. The COVID-19 pandemic led to increase prevalence of ASS cases and to a remarkable shift in the anti-ARS antibodies profile, with increased frequency of anti-PL7 antibodies. Further studies are needed to investigate the link between SARS-CoV-2 infections and myositis.References[1]Witt LJ, et al. The Diagnosis and Treatment of Antisynthetase Syndrome.

TYPE I INTERFERON SCORE IS ASSOCIATED WITH THE SEVERITY AND POOR PROGNOSIS IN ANTI-MDA5 ANTIBODY-POSITIVE DERMATOMYOSITIS PATIENTS

BackgroundAnti-MDA5 antibody-positive dermatomyositis (anti-MDA5+DM) is a rare autoimmune disease associated with a high mortality rate due to rapid-progressive interstitial lung disease (RP-ILD), particularly in East Asia[1]. MDA5, acts as a cytoplasmic sensor of viral RNA, thus activating antiviral responses including the type I interferon (IFN) signaling pathway[2]. The involvement of type 1 IFN in the pathogenesis of MDA5+DM has been proposed based on the significantly elevated expression of its downstream stimulated genes(ISG) in muscle, skin, lung, and peripheral blood[3;4]. Janus kinase inhibitor, which targets the IFN pathway, combined with glucocorticoid could improve the survival of early-stage MDA5+DM-ILD patients[5]. In clinical practice, there is still an urgent demand for sensitive biomarkers to facilitate clinical risk assessment and precise treatment.ObjectivesThis study aimed to investigate the clinical significance of interferon score, especially IFN-I score, in patients with anti-MDA5+DM.MethodsDifferent subtypes of idiopathic inflammatory myopathy, including anti-MDA5+DM(n=61), anti-MDA5-DM(n=20), antisynthetase syndrome(ASS,n=22),polymyositis(PM,n=6) and immune-mediated necrotizing myopathy(IMNM,n=9), and 58 healthy controls were enrolled.. A multiplex quantitative real-time PCR(RT-qPCR) assay using four TaqMan probes was utilized to evaluate two type I ISGs (IFI44, MX1, which are used for IFN-I score), one type II ISG (IRF1), and one housekeeping gene (HRPT1). Clinical features and disease activity index were compared between high and low IFN-I score groups in 61 anti-MDA5+DM patients. The association between laboratory findings and the predictive value of baseline IFN-I score level for mortality was analyzed.ResultsThe IFN scores were significantly higher in patients with anti-MDA5+DM than in HC (Figure 1A). The IFN-I score correlated positively with serum IFN α(r = 0.335, P =0.008), ferritin (r = 0.302, P = 0.018), and Myositis Disease Activity Assessment Visual Analogue Scale (MYOACT) score(r=0.426, P=0.001). Compared with patients with low IFN-I scores, patients with high IFN-I scores showed increased MYOACT score, CRP, AST, ferritin, and the percentages of plasma cells (PC%) but decreased lymphocyte count, natural killer cell count, and monocyte count. The 3-month survival rate was significantly lower in patients with IFN-I score > 4.9 than in those with IFN-I score ≤ 4.9(72.9% vs. 100%, P=0.044)(Figure 1B).ConclusionIFN score, especially IFN-I score, detected by multiplex RT-qPCR, can be a valuable biomarker for monitoring disease activity and predicting mortality in anti-MDA5+DM patients.References[1]I.E.

Impact of Vitamins on immunity

Human beings were blessed with two kinds of immunity, born immunity and acquired immunity. As a multisystem organism, we have distinct functions to carry out for the duration of our life. We are not the simplest ones residing on earth;however, different microorganisms coexist with us in near proximity. In a manner, we are making a symbiotic relationship with the opposite microorganism. Sometimes those can become dominant species and might invade the human body. As we are blessed with our immune system, we are able to prevent them. In a contemporary situation, nutrients and minerals have played a considerable function in immunity booster within the COVID-19. Wuhan changed the origin of this deadly virus, which brought on a pandemic in 2020. Basically, COVID-19 virus attacks the immune system and turns on distinct inflammatory modulators, which seriously affect the human body. A scientific practitioner and a team of researchers observed that multivitamins and some micronutrients can assist to enhance the immune system. Vitamins, including A, B, C, D, K and micro vitamins together with zinc, sodium, potassium, and calcium, play a main function in such deadly diseases. In this chapter, we have focused at the function of nutrients within the immunity and immune associated diseases. © 2023 Scrivener Publishing LLC. All rights reserved.

RETROSPECTIVE STUDY OF VITAMIN D DEFICIENCY IN RHEUMATOLOGIC PATIENTS DURING THE COVID-19 PANDEMIC IN POLAND

BackgroundBefore the COVID-19 pandemic it was estimated that nearly 70% of the population is deficient in vitamin D - 25(OH)D <20ng/ml in Poland [1]. The percentage was expected to increase due to indoor isolation during the COVID-19 pandemic. Vitamin D has a positive effect on the condition of the bones, affects the course of autoimmune diseases, the course of neurological diseases, in type 2 diabetes, vitamin D supplementation improves glucose tolerance and reduces insulin resistance [2,3,4].ObjectivesThe aim of the retrospective study was to determine what percentage of rheumatology clinic patients suffer from vitamin D deficiency and whether this condition is effectively treated.MethodsIn January 2023, a retrospective analysis of the documentation of 172 patients treated at the Rheumatology Outpatient Clinic in Bełżyce (Poland) in 2022 was conducted.ResultsResults: The mean age of the 172 patients whose documentation was analyzed was 60.43 years (min 19, max 88). There were 132 women (76.8%) and 40 men (23.2%) in this group. The mean concentration of vitamin D was 25.57ng/ml±SD11.9 (min 5.7, max 75, Me 22.8). Vitamin D deficiency was found in 44% (serum concentration <20mg/ml), suboptimal concentration (20-30ng/ml) in 31%, optimal concentration (30-50ng/ml) in 21%, and high concentration (>50ng/ml) ml) in 4%. All those with a deficit or deficiency (75 people) were prescribed cholecalciferol in a dose of 20,000 units orally, 1 capsule twice a week after breakfast for 2 months [5]. Patients with optimal vitamin D levels were advised to take a dose of 2,000 units per day. Among the patients with deficit or deficiency, 48 people came for a follow-up visit to check the level of vitamin D (64% of the group with too low vitamin D concentration;28% of the entire group whose documentation was analyzed). In the follow-up examination, the mean concentration of vitamin D was 37.14±9.8ng/ml (min 28, max 84, Me 35.3). Therefore, a statistically significant increase in the concentration of vitamin D in the blood was noted (p<0.05). In the group of people who came for the follow-up examination, there were 35 women, whose mean age was 60.7 years and 13 men (mean age 68.2 years).Conclusion:1. During the COVID-19 pandemic in the group of outpatient rheumatology patients, 75% had a deficiency or suboptimal level of vitamin D.2. Treatment with cholecalciferol in a dose of 20,000 IU twice a week orally for 2 months is effective treatment of vitamin D deficiency.3. Too low percentage of patients diagnosed with vitamin D deficiency come for visits and check-ups.References[1]Hilger J., Friedel A., Herr R..

COVID-19 OUTCOME IN AN ITALIAN RHEUMATOID ARTHRITIS COHORT

BackgroundIt is known that rheumatologic patients often present a course of COVID-19 similar to that of the general population. Some factors are linked to a worse COVID-19 outcome, such as moderate glucocorticoid (GC) dose, high body mass index (BMI), and comorbidities.ObjectivesTo describe the outcome of COVID-19 in patients with rheumatoid arthritis (RA) in terms of symptoms, therapy and need for hospitalization compared to a control group. Also, to evaluate the variation in disease activity before and after COVID-19.MethodsIn this monocentric prospective study, we recruited consecutive adult patients with RA classified according to ACR-EULAR 2010 criteria who received a diagnosis of COVID-19 through molecular or rapid antigen swab tests between September 2020 and December 2022. Demographic and clinical data, including age, BMI, smoking habit, comorbidities, treatment at the diagnosis of COVID-19, duration of COVID-19, symptoms related to the infection and therapy required, together with the vaccination status were collected through a self-administered questionnaire. We compared DAS28-CRP before the infection and at the first visit after the resolution. As controls (Cs), individuals with COVID-19 but with no referred diagnosis of rheumatic/autoimmune disease were recruited.ResultsWe enrolled 111 patients affected by RA (males 15%, median age 56 years, IQR 25) and 89 Cs (males 44%, median age 47 years, IQR 43), whose demographic and clinical characteristics are reported in Table 1. The median RA disease duration was 108 months (IQR 201). At the COVID-19 diagnosis, 62 patients (56%) were assuming csDMARDs, 67 (60%) bDMARDs, and 18 (16%) GC with a median prednisone equivalent dose of 4 mg/day (IQR 1). DAS28-CRP was available for 62 patients, with a median value of 1.67 (IQR 2.71);42 patients (60%) were in remission (Figure 1). Before developing COVID-19, only 35 (32%) RA patients and 42 (47%) Cs had completed the vaccinal cycle, which was performed by mRNA vaccine in all the patients and 87% of Cs. The median COVID-19 duration was 18 days (IQR 18) for RA patients and 14 days (IQR 13.5) for Cs (p>0.7). Cs reported a significantly higher frequency of constitutional symptoms (headache and asthenia) compared to RA patients (p<0.00001). When hospitalization was required, RA patients received heparin more frequently than Cs (p<0.039). Once COVID-19 was resolved, RA patients were evaluated after a median of 2 months (IQR 2). DAS28-CRP was available for 68 patients, with a median value of 1.61 (IQR 1.77);42 patients (68%) were in remission (Figure 1).No differences in terms of COVID-19 duration, clinical manifestations, and therapy emerged comparing RA patients in remission (40;58%) with patients with the active disease before COVID-19 (29;42%). Also, in vaccinated subjects, the outcome of COVID-19 was similar in RA patients and Cs, irrespective of RA activity.ConclusionCOVID-19's impact on patients with RA was not significantly different from the general population, even for patients with active RA. Patients did not suffer from reactivation of RA because of COVID-19. In our opinion, these positive results could be ascribed to the massive vaccination campaign.References[1]Conway R et al, Ir J Med Sci. 2023[2]Andersen KM et al, Lancet Rheumatol. 2022Table 1.Clinical characteristics, COVID-19 symptoms, and therapy of the two groups.

CLINICAL COURSE IN COVID 19 DISEASE IN IMMUNOSUPRESSED PATIENTS DIAGNOSED WITH RHEUMATIC DISEASES

BackgroundPatients with pre-existing rheumatic diseases may be exacerbated during SARS-CoV-2 infection, or may develop new autoimmune features. Furthermore, immunosuppressive agents used to treat autoimmunity-inflammation as well as comorbidities can also affect the disease outcome.ObjectivesTo evaluate the outcome of rheumatic diseases after Covid 19 infection in patients diagnosed with rheumatic diseases, under various immunosuppressive treatment, as well as the effects of vaccines against Covid or antiviral treatment in this sensitive population group.MethodsDuring the pandemic, 1493 patients with autoimmune or autoinflammatory disease who were continuously followed up in two tertiaries hospitals in northern and northwestern Greece were included in the current study. The patients were compared with 769 controls after adjustment for age, sex, weight, vaccination status and comorbidities. Of the 1493 patients, 648 had rheumatoid arthritis, 282 psoriatic arthritis, 173 ankylosing spondylitis, 122 systemic lupus erythematosus, 98 Sjogren's syndrome, 43 polymyalgia rheumatica, 34 mixed connective tissue disease or overlapping syndromes, 31 vasculitis, 27 systemic sclerosis, 18 myositis, 10 Behcet syndrome, 5 primary antiphospholipid syndrome and 2 had Familial Mediterranean Fever. The vast majority of patients and controls were fully vaccinated (82%) and 397 patients received antiviral treatment, 94% of them were fully vaccinated.ResultsCovid 19 disease in vaccinated patients with rheumatic diseases was shown to perform the same or about the same as those in the control group after adjustment for risk factors for severe disease. 19 of our patients required admission in the intensive care unit (62% full vaccinated) while a total of 12 died (66% non vaccinated). Major risk factors for severe disease were previous respiratory failure, chronic renal impairment, obesity, and failure to receive antiviral therapy. It was also shown that infection with Covid led to an exacerbation or induction of autoimmune disorders in 25 of the participants.ConclusionIn this large cohort, Covid 19 disease was shown to affect patients with autoimmune rheumatic diseases the same or approximately the same way as the general population if they are fully vaccinated and if they start timely antiviral treatment where indicated. Further research and monitoring of the results after the multiple mutations of the virus is advisable.ReferencesNone.Acknowledgements:NIL.Disclosure of InterestsNone Declared.

CHALLENGES FOR PATIENTS WITH RMD'S IN BULGARIA DURING THE COVID-19 PANDEMIC

BackgroundThe Covid-19 pandemic has put patients with rheumatic diseases in front of a number of obstacles that had to be solved together with Bulgarian rheumatologists. The lockdowns and restrictive measures have made it difficult for people with rheumatic diseases to have access to timely hospital and pre-hospital care. A number of digital solutions have been implemented to address these issues.ObjectivesTo highlight the problems that patients with rheumatic diseases had during the Covid-19 pandemic;access to rheumatologists and the effectiveness of hospital and pre-hospital care during the pandemic, access to treatment, changes of treatment;communication between physicians and patients, the impact of the pandemic on work, social contacts, hobbies.MethodsAn anonymous survey was conducted online and by telephone. The survey was developed by Medical university, Plovdiv, University hospital "Kaspela”:, Plovdiv, Bulgarian Association for Musculoskeletal Ultrasound, Bulgarian organization for people with rheumatic diseases;Association for patients with autoimmune diseases.Number of participants: 1205 patients with RMD's.Age range: 18-82ResultsFace to face meetings with doctors have been limited during the pandemic.Visits to the rheumatologist's office are significantly reduced and phone, email, text messaging, online consultations were preferred as communication channels.Before the pandemic, 76% of respondents most often communicated with their physicians by visiting their practice, during the pandemic their relative share decreased to 46%, with a significant difference of 30%Phone consultations: patients using this type of communication increasing from 38% before the pandemic to 56% during the pandemic, a significant difference of 18%The percentage of patients who communicated via text or email rises from 10% to 17 %.It has become apparent that Digital transformation is needed and patients and physicians should work together to achieve it and to be established in Bulgaria.245 patients reported a change in their treatment. Of these: (30%) reduced the dose of their medications, 119 (49%) increased the dose and the remaining 55 (21%) stopped their therapy.From the responses of the respondents, it is clear that 71% have not experienced a change in their work during the COVID-19 pandemic, 17% have worked from home.From the responses of the respondents, it is clear that 71% have not experienced a change in their work during the COVID-19 pandemic, 17% have worked from home, 4% have been fired, 3% have left their jobs due to the risk of their health and 5% left their jobs for other reasons.ConclusionThe Covid-19 pandemic has shown that the digital transformation in rheumatology care can be an efficient alternative to some of the services offered to patients with rheumatic diseases in Bulgaria (especially secondary examinations and therapy monitoring examinations). The results of the conducted survey could be used to support digitization in healthcare in Bulgaria.Very important was the collaboration between the patient organizations and the Bulgarian Association for Musculoskeletal Ultrasound, Medical University, Plovdiv and the rheumatologists from University hospital "Kaspela” Plovdiv.References[1]Gianfrancesco M, Hyrich KL, Al-Adely S, et al.

NEW INSIGHTS ON EPIDEMIOLOGICAL DATA AND IMPACT OF THE COVID-19 PANDEMIC ON IGA VASCULITIS IN CHILDREN AND ADULTS IN FRANCE: A NATIONWIDE COHORT

BackgroundIgA vasculitis (IgAV) is a rare autoimmune disease affecting small vessels. It is well established that the incidence is higher in children (3 to 26 per 100,000 children/year,) [1] than in adults (0.1 to 1.8 per 100,000 individuals/year) [1]. However others epidemiological data and impact of the COVID-19 on IgAV remain overlooked [2].ObjectivesTo collect and analyze epidemiological data on IgAV in both adults and children in France.MethodsWe conducted an observational study using a national database called "BNDMR” [3] (Banque Nationale de Données Maladies Rares) on IgA vasculitis (code ORPHA761), which gathered patients managed in the French rare disease expert network. The incidence was estimated from the date of diagnosis, and we calculated the median annual incidence over the period 2010-2022. We specifically assessed the north/south gradient (latitude of the residence higher/lower than the median of the latitudes), the seasonality, and the impact of the COVID-19 pandemic compared to other patients reported within the same period and addressed in the same expert centers used as controls.ResultsDuring this 12-year period, 1988 patients with IgAV were reported (1498 children;490 adults). The male to female ratio was 1.57 for adults and 1.05 for children. The median IgAV annual incidence was 15 cases/year [IQR 9-30] and 82 cases/year [IQR 72-86] for adult and children cases respectively. Time to diagnosis was less than 1 month for both. Compared with other patients reported in the same expert centers, IgAV was more frequently reported in the southern part of France than in the north (OR 4.88 [95% confidence intervals: 4.17 - 5.74] in adults and OR 1.51 [1.35 - 1.68] in children). IgAV was also more frequently observed in winter than during the rest of the year in both adults (OR 1.60 [1.39 - 1.82]) and children (OR 1.22 [1.01 - 1.48]). The incidence of IgAV decreased during the COVID-19 pandemic period (from March 2020 to September 2022) in children (OR 0.62 [0.47 - 0.81]) but not in the adult population (OR 0.90 [0.76 - 1.06]).ConclusionOur study confirms the winter seasonality and sex ratio in IgAV [4,5], but suggests that the incidence or the reporting of IgAV decreased in children during the COVID19 pandemia, possibly due to barrier measures [6]. The observed north/south gradient need confirmation. The main limitation of this study is a possible IgAV under-reporting as this study rely only on cases addressed in expert centers.References[1]Audemard-Verger A, Pillebout E, Guillevin L, Thervet E, Terrier B.

COVID-19 SYMPTOMS AND DISEASE COURSE IN GERMAN PEDIATRIC RHEUMATOLOGY PATIENTS REPORTED TO BIKER

BackgroundCOVID-19 has shaped the world over the last 3 years. Although the risk for severe COVID-19 progression in children is low it might be aggravated by chronic rheumatic disease or treatment with immunosuppressive drugs.ObjectivesWe analyzed clinical data of COVID-19 cases among paediatric patients with rheumatic diseases reported to BIKER between March 2020 and December 2022.MethodsThe main task of the German BIKER (Biologics in Pediatric Rheumatology) registry is safety monitoring of biologic therapies in JIA. After the onset of the COVID-19 pandemic, the survey was expanded with a standardized form to proactively interview all participating centers about occurrence, presentation and outcome of SARS-CoV-2 infections in children with rheumatic diseases.ResultsA total of 68 centres participated in the survey. Clinical data from 928 COVID infections in 885 patients with rheumatic diseases could be analyzed. JIA was the most common diagnosis with (717 infections), followed by genetic autoinflammation (103 infections), systemic autoimmune diseases (78 infections), idiopathic uveitis (n=25), vasculitis (n=5).In 374 reported COVID infections (40%), patients were receiving conventional DMARDs, in 331 (36%) biologics, mainly TNF inhibitors (TNFi, n=241 (26%)). In 567 reports (61%) patients used either a biologic or a DMARD, in 339 reports patients (37%) did not use any antirheumatic medication including steroid.Over the last 3 years, COVID-19 occurred in Germany in 5 distinguishable waves, calendar weeks (CW) 10-30 in 2020, CW 21/2020 – 8/2021(both predominantly wild-type variant), CW 9-27 in 2021 (Alpha variant in the majority of infections), CW 28-51 in 2021 (Delta variant), since CW 52/2021 (several Omikron variants;Robert-Koch Institute: VOC_VOI_Tabelle.xlsx;live.com))In our cohort, patients with SARS-CoV-2 infection were slightly older during the 1st and 2nd wave (mean age 12.7+/-3.5 and 12.8+/-4.3 years) compared to the 4th and 5th wave with 11.4+/-3.9 and 11.4+/-4.2 years;p=0.01.160 asymptomatic SARS-CoV-2 infections were reported, frequencies of symptoms associated with COVID-19 are shown in table 1.Five patients were hospitalized for 4-7 days. A 3½-year-old female patient succumbed during the first wave with encephalopathy and respiratory failure. The patient had been treated with MTX and steroids for systemic JIA. Genetic testing revealed a congenital immunodeficiency. No other patient needed ventilation or intensive care. One case of uncomplicated PIMS in an MTX treated JIA patient was reported.The duration of SARS-CoV-2 infection-associated symptoms was markably shorter during the 5th wave with 6.7+/-5.1 days, compared with reports from the other 4 waves (Table1).The duration of symptoms was higher in MTX treated patients (10.2+/-8.4 days) compared to patients without treatment (7.7+/-10.8;p=0.004) or patients treated with TNFi (8.2+/-4.8, p=0.002). Although patients treated with steroids also had a longer duration of symptoms (9.7+/-7.0), this was not significant.ConclusionExcept for one patient with congenital immunodeficiency who died, no case of severe COVID-19 was reported in our cohort. At the time of infection, over 60% of patients had been treated with conventional DMARDs and/or biologics. Although MTX treated patients had a slightly longer duration of symptoms, antirheumatic treatment did not appear to have a negative impact on severity or outcome of SARS-CoV-2 infection.Table 1.Characteristics and frequency of symptoms in SARS-CoV-2 infectionsN or mean (SD)1st wave N=202nd wave N=843rd wave N=384th wave N=1245th wave N=662female14532775432age at COVID-19, years12.7 (3.5)12.8 (4.3)11.8 (3.5)11.4 (3.9)11.4 (4.2)asymptomatic126132694duration of symptoms;days,11.9 (14.7)9.2 (7.0)14.1 (11.6)10.3 (7.6)6.7 (5.1)fever1218541306cough1015652245rhinitis5261344289headache4161227171sore throat61139132musculosceletal pain2751348loss of smell/taste71162113fatigue4882680dizziness122116gastrointestinal symptoms151864dyspnea1117pneumonia11bronchitis1REFERENCES:NIL.Acknowledgements:NIL.Disclosure of Inter stsAriane Klein Speakers bureau: Novartis, Toni Hospach Speakers bureau: Speaking fee Novartis and SOBI., Frank Dressler Speakers bureau: Abbvie, Novartis, Pfizer, Advisory Boards Novartis and Mylan, Daniel Windschall Grant/research support from: research funds by Novartis, Roche, Pfizer, Abbvie, Markus Hufnagel: None declared, Wolfgang Emminger: None declared, Sonja Mrusek: None declared, Peggy Ruehmer: None declared, Alexander Kühn: None declared, Philipp Bismarck: None declared, Maria Haller: None declared, Gerd Horneff Speakers bureau: Pfizer, Roche, MSD, Sobi, GSK, Sanofi, AbbVie, Chugai, Bayer, Novartis, Grant/research support from: Pfizer, Roche, MSD, AbbVie, Chugai, Novartis.

DERMATO-NEURO SYNDROME PRECIPITATED BY COVID-19 INFECTION IN THE SETTING OF SCLEROMYXEDEMA

BackgroundA black female in her 40s presented with a nonpruritic rash for 10 months consisting of bumps on the face, hands, forearms, and thighs. She had no prior treatment. Past medical history was significant for pulmonary embolism (PE) 6 years prior. She had no personal or family history of autoimmune disease. Physical exam revealed numerous smooth 2-3 mm skin-colored papules over the bilateral forearm dorsa, hands, anterior thighs, and face. Serum protein electrophoresis revealed monoclonal IgG lambda gammopathy. Skin biopsy of her left elbow showed dermal fibroplasia with mucin deposition. IgG was less than 1.5 grams/deciliter;bloodwork was otherwise stable. The diagnosis of scleromyxedema was rendered.ObjectivesThe objective of this clinical case was to evaluate a neurologic sequela of COVID-19 infection in a patient with scleromyxedema.MethodsOne month following diagnosis of scleromyxedema, our patient was diagnosed with COVID-19 five days before admission to the emergency department with altered mental status and aphasia. Rheumatology was consulted due to malignant hypertension and acute kidney injury with question of scleroderma-like renal crisis in the setting of recently diagnosed COVID-19 infection, although she had no other features of systemic sclerosis. The infectious disease team was consulted due to COVID-19-induced inflammatory reaction.ResultsThe patient's creatinine kinase and brain natriuretic peptide were elevated. Creatinine and potassium trended upwards. She developed seizures and became hemodynamically unstable with rapidly declining clinical status. She was transferred to the intensive care unit, where she developed respiratory arrest, shock, hyperkalemia, and acidemia. She received escalating doses of pressors but experienced frequent arrhythmic disturbances and developed asystole. Resuscitation efforts were unsuccessful;she expired within 24 hours of consultation.ConclusionDermato-neuro syndrome (DNS) is a potential complication of scleromyxedema associated with confusion, dysarthria, seizures, and coma. The patient's clinical presentation is consistent with DNS in the setting of scleromyxedema likely precipitated by COVID-19. Intravenous immunoglobulins are first-line treatment for scleromyxedema;however, it is associated with risk of venous thromboembolism. The patient was considered for treatment as an outpatient but deferred due to history of PE. She was reevaluated for treatment upon presentation to the hospital, but given the severity and rapidity of her condition, it was already too late. This is the second reported case of COVID-19 induced DNS in a patient with scleromyxedema. Given the severity, we recommend early initiation of treatment in patients with scleromyxedema and aggressive treatment for those contracting COVID-19.References[1] Haber R, Bachour J, El Gemayel M.

COVID-19 VACCINE SAFETY DURING PREGNANCY IN WOMEN WITH SYSTEMIC LUPUS ERYTHEMATOSUS

BackgroundVaccinations comprise a part of the antenatal care of pregnant women, including patients with systemic lupus erythematosus (SLE) who are at increased risk of adverse pregnancy outcomes (APOs). While COVID-19 vaccination has been shown to be safe in patients with SLE, data on vaccine-associated adverse events (AEs) during the antenatal and lactation period are scarce or lacking.ObjectivesTo investigate the association between COVID-19 vaccination and AEs in pregnant SLE patients.MethodsA total of 9201 complete responses were extracted on June 21st, 2022 from the COVID-19 Vaccination in Autoimmune Diseases (COVAD) 2 database, a global e-survey involving 157 collaborators from 106 countries. Among respondents, 6787 (73.8%) were women. We identified 70 (1.1%) women who were exposed to at least one COVID-19 vaccine dose during pregnancy, among those 11 with SLE. Delayed onset (>7 days) vaccine-related AEs were extracted and triangulated with disease activity, treatment changes due to flare after vaccination, and COVID-19 infections in vaccinated pregnant women with SLE. Additionally, information on health-related quality of life and physical function was recorded using PROMIS at the time of survey completion.ResultsThe age of patients ranged from 28 to 39 years;5/11 women were of Asian origin. None of these patients reported major vaccine AEs, including four patients with self-reported active SLE prior to the vaccination. None of them reported any change in the status of their autoimmune disease, and no hospitalisation or special treatment was recorded. Six women experienced minor vaccine AEs;two of them had active disease prior to vaccination. Four patients reported COVID-19 infection;two of them while they were pregnant and post-vaccination and two prior to pregnancy and vaccination. All four patients experienced symptoms of their disease, but no overt SLE flare was reported. At the time of survey completion, all patients reported their general health as being good to excellent in all aspects evaluated. Importantly, no APOs were reported.None of the patients reported thrombotic events post-vaccination, which provides some reassurance regarding COVID-19 vaccination in a patient population with a high risk for cardiovascular comorbidity and thrombosis, especially in the presence of antiphospholipid antibodies or in patients diagnosed with the antiphospholipid syndrome, a considerable portion within SLE populations. Moreover, it was reassuring to note an absence of association between experienced vaccine AEs and active disease prior to vaccination. Although minor AEs were common, they did not impair daily functioning, and the symptoms resolved in all patients after a median of 3 (IQR: 2.5–5.0) days.ConclusionOur report adds relevant evidence concerning the sensitive issue of COVID-19 vaccine AEs and flares in SLE patients during the antenatal and lactation period. Despite the small sample size, the findings provide some reassurance and can contribute to informed decisions regarding vaccination in patients with SLE and high-risk pregnancies due to their background autoimmune disease. Based on the present data, the risk/benefit ration of COVID-19 vaccination appears favourable, with vaccines both providing passive immunisation to the fetus and active immunisation to the mother with no signals of exacerbation of the mother's autoimmune disease.Figure 1.Timeline showing COVID-19 vaccination and vaccination-related minor adverse events in relation to gestational and post-partum periods in eleven pregnant/lactating women with systemic lupus erythematosus.[Figure omitted.

BREAKTHROUGH SARS-COV-2 INFECTION IN FULLY VACCINATED PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS: RESULTS FROM THE COVID-19 VACCINATION IN AUTOIMMUNE DISEASE (COVAD) STUDY

BackgroundAlthough many studies have been conducted on COVID-19 in recent years, there are still unanswered questions regarding breakthrough infections (BTIs), particularly in patients with systemic lupus erythematosus (SLE).ObjectivesThis study aimed to determine the occurrence of breakthrough COVID-19 infections in patients with SLE versus other autoimmune rheumatic diseases (AIRDs), non-rheumatic autoimmune diseases (nrAIDs), and healthy controls (HCs).MethodsThe study was based on data from the COVAD questionnaire which amassed a total of 10,783 complete responses from patients with SLE, AIRD, or nrAIRD, and HCs. After exclusion of individuals who were unvaccinated, those who received one vaccine dose only, and those with uncertain responses regarding the vaccine doses, a total of 9,595 patients formed the study population of the present investigation. If a COVID-19 infection occurred after the initial two vaccine doses and at least one booster dose (at least three doses in total, herein termed full vaccination), it was considered a BTI. Data were analysed using multivariable regression models. Statistically significant results were denoted by p values <0.05.ResultsA total of 7,016/9,595 (73.1%) individuals were fully vaccinated. Among those, 1,002 (14.2%) reported at least one BTI, and 166 (2.3%) reported at least two BTIs. Among SLE patients, 867/1,218 (71.2%) were fully vaccinated. Among fully vaccinated SLE patients, 137 (15.8%) reported at least one BTI while 28 (3.2%) reported at least two BTIs. BTI frequencies in fully vaccinated SLE patients were comparable to those of other AIRDs (OR: 1.0;95% CI: 0.8–1.3;p=0.447) and nrAIDS (OR: 0.9;95% CI: 0.6–1.3;p=0.856) but higher compared with HCs (OR: 1.2;95% CI: 1.0–1.6;p=0.022).For SLE patients with three vaccine doses, 113/137 (82.5%) reported at least one BTI while the corresponding number for four vaccine doses was 24/137 (17.5%). Compared with HCs (OR: 10.6;95% CI: 1.2–93.0;p=0.032) and other AIRDs (OR: 3.5;95% CI: 1.08–11.5;p=0.036), SLE patients showed higher frequencies of hospitalisation.AID multimorbidity was associated with a 15-fold increased risk for a need of advanced treatment for COVID-19 (OR: 15.3;95% CI: 2.6–88.2;p=0.002).ConclusionCOVID-19 BTIs occurred in nearly 1 every 6th fully vaccinated patient with SLE, and 20% more frequently in this patient population compared with fully vaccinated HCs. Moreover, BTIs in SLE patients were more severe compared with BTIs in HCs or patients with AIRDs other than SLE, resulting in a greater need for hospitalisation. AID multimorbidity contributed to a more severe COVID-19 BTI requiring advanced management. These insights call for greater attention to vaccination in the vulnerable group of SLE patients, with appropriate risk stratification towards optimised vaccination strategies.Figure 1.Survival analysis across patients with SLE, AIRDs, or nrAIDs, and HCs.

SYSTEMIC SCLEROSIS AND COVID-19 VACCINE-ASSOCIATED DELAYED ADVERSE EVENTS: INSIGHTS FROM THE COVAD-2 STUDY

BackgroundWe have previously reported short term safety of the COVID-19 vaccination in patients with Systemic sclerosis (SSc) but delayed adverse events (ADEs) (occurring >7 days post-vaccination) are poorly characterized in this rare yet vulnerable disease group.ObjectivesWe analyzed delayed COVID-19 vaccine-related ADEs among patients with SSc, other systemic autoimmune and inflammatory disorders (SAIDs) and healthy controls (HC) using data from the ongoing 2nd global COVID-19 Vaccination in Autoimmune Diseases (COVAD-2) study [1].MethodsThe COVAD-2 study was a cross-sectional, patient self-reporting e-survey utilizing an extensively validated, pilot tested questionnaire, translated into 19 languages, circulated by a group of 157 physicians across 106 countries from February to June 2022.We captured data on demographics, SSc/SAID disease characteristics (including skin subset, treatment history and self-reported disease activity), autoimmune and non-autoimmune comorbidities, COVID-19 infection history and course, and vaccination details including delayed ADEs as defined by the CDC.Delayed ADEs were categorized into local injection site pain/soreness;minor and major systemic ADEs, and hospitalizations. We descriptively analyzed the risk factors for overall and specific ADEs in SSc and SAIDs, and further triangulated clinically significant variables in binominal logistic regression analysis with adjustment for age, gender, ethnicity, comorbidity, and immunosuppressive therapy to analyze the survey responses.ResultsFrom among 17 612 respondents, 10 041 patients (median age 51 (18-58) years, 73.4% females, 44.9% Caucasians) vaccinated against COVID-19 at least once (excluding incomplete responses and trial participants) were included for analysis. Of these, 2.6 % (n=258) had SSc, 63.7% other SAIDs, and 33.7% were HCs. BNT162b2 Pfizer (69.4%) was the most administered vaccine, followed by MRNA-1273 Moderna (32.25%) and ChadOx1 nCOV-19 Oxford/AstraZeneca (12.4%) vaccines.Among the patients with SSc, 18.9% reported minor while 8.5% experienced major delayed ADEs, and 4.6% reported hospitalization. These values were comparable to those of the ADEs reported in other SAIDs and HCs. Patients with SSc reported higher frequency of difficulty in breathing than HCs [OR=2.3 (1.0-5.1), p=0.042].Individuals receiving Oxford/AstraZeneca reported more minor ADEs [OR=2.5 (1.0-6.0), p=0.045];whereas patients receiving Moderna were less likely to develop myalgia and body ache [OR=0.1 (0.02-1.0), p=0.047 and OR=0.2 (0.05-1.0), p=0.044 respectively].Patients with diffuse cutaneous SSc experienced minor ADEs and specifically fatigue more frequently [OR=2.1 (1.1-4.4), p=0.036, and OR=3.9 (1.3-11.7), p=0.015] than those with limited cutaneous SSc. Self-reported active disease pre-vaccination did not confer any increased risk of vaccine ADEs in the adjusted analysis. Unlike our previous observations in myositis, autoimmune and non-autoimmune comorbidities did not affect the risk of delayed ADEs in SSc. SSc patients with concomitant myositis reported myalgia [OR=3.4 (1.1-10.7), p=0.035] more frequently, while those with thyroid disorders were more prone to report a higher frequency of joint pain [OR=5.5 (1.5-20.2), p=0.009] and dizziness [OR=5.9 (1.3-27.6), p=0.024] than patients with SSc alone. Patients with SSc-interstitial lung disease did not report increased frequency of ADEs.ConclusionA diagnosis of SSc did not confer a higher risk of delayed post COVID-19 vaccine-related ADEs than other SAIDs and HCs. Diffuse cutaneous phenotype and certain co-existing autoimmune conditions including myositis and thyroid disease can increase the risk of minor ADEs. These patients may benefit from pre-vaccination counselling, close monitoring, and early initiation of appropriate care in the post COVID-19 vaccination period.Reference[1]Fazal ZZ, Sen P, Joshi M, Ravichandran N, Lilleker JB, et al.

Technological Mapping of Plant-Derived Immunomodulator Drugs: A Patent-Guided Overview about Species and its Main Compounds

Research on natural products has investigated and employed many (bio)technologies to find out plant active fractions and optimize extraction and isolation of molecules looking for innovative clinical therapies for several clinical conditions, as well as immune-related diseases. Indeed, the world incidence and prevalence of autoimmune diseases have increased over the last years, while immune therapy has arisen as a new promising tool for cancer treatment. Also, in the emergence of COVID-19 pandemic, immunomodulation has been proved effective to reduce the "cytokine storm” and avoid worsening the clinical condition of patients in the acute stage of respiratory syndrome. These health issues have also driven the search for new immunomodulatory compounds. In this context, prospective analysis is an important tool to identify the most relevant opportunities and demands in research and development (R&D) of pharmaceutical medicines, including substances able to modulate immune and inflammatory responses. In addition, prospection allows understanding the landscape of immunomodulatory plant-derived drugs and the associated technologies described in patents. This chapter employed the descriptors "Immunomodulator*” and "drug” and "plant” in search strategy to map the technological potential of immunomodulatory herbal drugs, using the software VantagePoint, Cortellis Competitive Intelligence, and Orbit Intelligence, respectively. The results provided quantitative data and technological indicators to drive future strategies for the development of these drugs. In conclusion, the most cited plant species in patents expressing molecules with immunomodulatory properties were Curcuma longa, Moringa oleifera, Remirea maritima, Maytenus ssp., Angelica sp., Fagopyrum esculentum, as well as plants from the families Leguminosae, Rosaceae, Iridaceae, Moraceae, and Amaranthaceae, among others. The main chemical classes implicated in immunomodulation were xanthones, coumarins, flavonoids, and (tri)terpenes. The technological mapping also showed that in the year 2002, there was an increased deposit of patents, reaching the highest peak in 2009 with 56 patents. Nowadays, the United States is the country with the biggest number of patents, followed by Canada, Australia, and Korea. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.

TIME MANAGEMENT AND RISK FACTORS IN LIFE-THREATENING ANCA-VASCULITIS

BackgroundAccuracy of diagnosis and prompt therapeutic intervention are the mainstay in patients with ANCA-associated vasculitis(AAV) suffering from life-threatening complications [1].However, there is no definition of therapeutic window in vital AAV, nor its impact on patient outcome regarding length of hospital stay, intensive care unit(ICU) admission or survival.ObjectivesThe aim of the study is to analyze the process of care from the perspective of time management in vital organ involvement AAV patients and to identify potential risk factors for ICU admission.MethodsA retrospective multicenter study identified AAV patients with life-threatening organ involvement, defined as alveolar hemorrhage, rapidly progressive renal failure, myocarditis and cerebral granuloma. Demographic data was collected. Key time frames were recorded, namely the interval from acute symptom onset to hospital presentation, days until imaging(plain X-ray, cardiac ultrasound, CT-scan), time to therapeutic intervention with corticosteroids or biologic/non-biologic immunosuppression(cyclophosphamide or rituximab) and to renal replacement therapy(RRT) or plasmapheresis. Time to ICU admission, hospital length-of-stay, Birmingham Vasculitis Activity Score(BVAS) were also noted. Statistical analysis was performed using SPSS and Chi-square and Pearson correlation tests were applied.Results66 patients with AAV were enrolled, out of which 17 fulfilled inclusion criteria. Mean age in the study group was 58.6±11.1 years old,10 patients(58.8%) were females and 7 (41.2%) males.11(64.7%) patients were c-ANCA positive, while 6 (35.3%) had p-ANCA and all were diagnosed with AAV prior to life-threatening event. Two patients had COVID-19 triggered AAV.In the study group, the most frequent critical organ suffering was rapidly progressive renal failure(12), followed by alveolar hemorrhages(10), 2 cerebral granulomas and one acute myocarditis. Three patients(17.6%) had more than one vital manifestation. Ten patients(58.8%) had more than three additional non-organ-threatening manifestations. Mean interval from AAV diagnosis to emergency admission was 30.1± 61.1 days, median 3 and from severe episode onset to hospitalization 1.65±0.18 days, median 1. There was only one death in the study group. Three patients were admitted in the ICU in 0.59±1.5 days following hospital presentation and required either RRT or plasma exchange within 2.66 days. Imaging examination was performed unanimously the day upon hospital admission. All patients received corticosteroids in the first 5.95±14.3 days, while immunosuppression was given to 13(76.5%) patients within 11.5±15.5 days from hospitalization.12 patients(70.5%) suffered from associated infections. Mean BVAS(13.6±6.76) correlated to ICU admission(p 0.013, r 0.58).Patients in ICU revealed higher BVAS(22±9.53) versus non-ICU(11.8±4.76).Hospital length of stay was 14.7±10.7 days(median 14) and showed no relationship to the type of severe organ involvement. The need for ICU caring was dominant in males(p 0.05) and confirmed in patients with proteinuria(p 0.012) and at least two major organ damage.ConclusionThis study shows that severity risk factors for potential ICU admission for life-threatening AAV appear to be male gender, proteinuria and the number of affected organs.Moreover, BVAS should be considered a useful tool to predict patients' risk for intensive care management since a higher score indicates a more aggressive disease.However, time to investigational or therapeutic intervention did not correlate to patient outcome in AAV.References[1]Geetha, D., Seo, P.
