ABSTRACT
BackgroundAcetaminophen (APAP = paracetamol) may potentially impact vaccine-associated immune responses as the intake of APAP has been associated with a worse outcome in tumor patients receiving checkpoint inhibitors.[1]Different DMARD regimen have been shown to impair the humoral immune response to mRNA SARS-CoV-2 vaccines in patients with rheumatoid arthritis but the effect of paracetamol has not been explored thus far.ObjectivesTo analyse whether the intake of APAP may interfere with antiviral humoral immune responses following two doses of an anti-SARS-CoV-2 mRNA based vaccine in patients with rheumatoid arthritis (RA) on DMARD therapy.MethodsThe RECOVER trial (Rheumatoid Covid-19 Vaccine Immune Response) was a non-randomised, prospective observational control group trial and enrolled 77 RA patients on DMARD therapy and 21 healthy controls (HC). We performed a posthoc analysis of blood samples taken before the first vaccine dose (T0), two (T1) and three (T2) weeks after the first and second vaccine dose, and at 12 (T3) weeks. APAP intake was measured using ELISA. The antibody response (anti-S) to the receptor binding domain (RBD) within the SARS-CoV-2 S1 protein was measured with the Elecsys Anti-SARS-CoV-2-S (Roche Diagnostics GmbH) test. The neutralizing activity NT50 at week 12 was assessed using an HIV-based pseudovirus neutralization assay against Wuhan-Hu-1.ResultsBaseline characteristics of participants are detailed in Table 1. The immunogenicity analyses were based on 73 RA patients after exclusion of 4 patients with previously unnoticed SARS-CoV-2 infection (positive for anti-nucleoprotein at baseline). APAP was detected in serum samples from 34/73 (25%) RA patients and in 7/21 (33%) HC (least at one timepoint T0, T1 and/or T2). APAP intake in HC did not affect levels of anti-S at any timepoint and all HC developed potent neutralizing activity (NT50 ≥ 250) at week 12. RA patients, who tested positive for APAP at T1, showed comparable anti-S levels at T1, T2 and T3 compared to RA patients not exposed to APAP. The detection of APAP at T2 corresponded to lower anti-S levels at T2 (Figure 1 A, B). The detection of APAP at T2 was associated with a significantly lower SARS-CoV-2 neutralizing activity at week 12 compared to patients without perivaccination APAP exposure (p =0.04) (Figure 1 C).ConclusionA decrease of antiviral humoral immune responses was observed in RA patients (but not in HC) who were exposed to APAP at the time of the second mRNA vaccine dose compared to patients in whom APAP was not detected. Our data suggest that the use of paracetamol within the time period around vaccination may impair vaccine-induced immune responses in patients with an already higher risk for blunted immune responses.Reference[1]Bessede A et al.

ABSTRACT
BackgroundCOVID-19 is associated with higher morbidity and mortality burdens in immunocompromised individuals, including patients with systemic lupus erythematosus (SLE;1). These patients might benefit from treatment with anti-SARS-CoV-2-specific antiviral agents and monoclonal antibodies, but clinical evidence is to date limited.Objectivesto comparatively assess the course of COVID-19 in patients with SLE treated or untreated with COVID-19-specific agents.MethodsPatients with SLE and COVID-19 treated with antivirals and/or monoclonal antibodies from February 2020 to December 2022 were identified within a three-centre cohort of tertiary referral centres and age-, sex- SLE extension- and SLE duration-matched 1:2 with patients with a history of untreated COVID-19. Data on COVID-19 presentation, course (including time to viral clearance) and sequelae, along with SLE treatment at COVID-19 onset and SLE course after COVID-19 were collected. COVID-19 severity at presentation was quantitated through a 0-4 analogue scale [2]. Data are expressed as median (interquartile range, IQR) unless otherwise specified.ResultsOver three years, 39% of patients with SLE had at least one COVID-19 event. Eighteen subjects (16 women) were treated with antivirals (n=12) or monoclonal antibodies (n=6) and were matched with 36 controls. There was no difference in the frequency of organ involvement between the two groups. Treated patients were receiving significantly higher prednisone daily doses at COVID-19 onset (6.25 (0-10) vs 0 (0-2.5) mg;p=0.005) and had a higher prevalence of previous high-dose steroid treatments (83% vs 47%;p=0.019) compared to controls. SLE disease activity index (3 (0-5) vs 1 (0-4)) and SLE International Collaborating Clinics Damage Index scores (1 (0-3) vs 0 (0-1)) were also numerically higher in treated patients at COVID-19 onset. Patients in the treated group had more severe COVID-19 at presentation but showed no significant differences with control subjects in terms of COVID-19 resolution, prevalence of sequelae and viral clearance (Table 1). There was also no difference in flare occurrence between the two groups (Log-rank=0.02, p=0.889). Two patients reported mild adverse events with monoclonal antibodies (muscle cramps and chest pain, both self-resolving).ConclusionThese data support the safe use of COVID-19 specific treatments in patients with SLE. Patients treated with antivirals and monoclonal antibodies had a favourable COVID-19 course, despite a more severe presentation and a higher risk of deterioration due to SLE and corticosteroid treatment burden, suggesting the potential efficacy of COVID-specific treatments in preventing severe COVID-19 in patients with SLE.References[1]Strangfeld A et al, Ann Rheum Dis, 2021[2]World Health Organization.

ABSTRACT
Objectives: While persistent and relapsing symptoms of COVID-19 are increasingly documented, limited data exist on the post-acute population. The objective of this analysis is to identify the characteristics of patients diagnosed with long COVID using real-world data. Method(s): Children/adolescents (age 0-17) and adults (age 18-39, 40-64 and >=65) with >=2 primary diagnoses for U09.9 "Post COVID-19 condition" from 10/01/2021 (ICD-10 code introduction) until 03/31/2022 were selected from Optum's de-identified Clinformatics Data Mart Database, with the first diagnosis deemed index. Included patients had >=1 diagnosis for COVID-19 and continuous enrollment 12 months prior to index (baseline). To ensure alignment with most institutional definitions, >=4 weeks between initial COVID-19 infection and index was required. Diagnoses recorded +/-2 weeks from index that were not present prior to the initial COVID-19 diagnosis were summarized. Newly prescribed treatments and total medical costs were evaluated during the month following index (continuous enrollment required). Result(s): 3,587 patients met eligibility criteria (mean age 59.02, 57.56% female) with a median time from initial COVID-19 infection to long COVID diagnosis of 83 days (IQR: 46-201 days). The most common concurrent diagnoses included breathing complications such as dyspnea (20.38%) and respiratory failure (15.23%);malaise and fatigue (15.31%);symptoms related to cognitive functioning/anxiety (11.35%);and chest pain (7.67%). Children/adolescents had the highest prevalence of chest pain, while patients >=65 years of age had the highest prevalence of issues with coordination. The average total medical cost during the month following long COVID diagnosis was $4,267 (SD $14,662), with common prescriptions including albuterol (4.42%), prednisone (3.51%), and methylprednisolone (2.01%). Conclusion(s): This retrospective analysis confirms clinically documented symptoms of long COVID in a large, real-world population. Once more data become available, further research on the long term economic and clinical outcomes among patients diagnosed with post-acute COVID-19 syndrome are warranted.Copyright © 2023
ABSTRACT
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.

ABSTRACT
BackgroundBelimumab (BLM) is a monoclonal antibody that inhibits B-lymphocyte stimulating factor (BlyS) approved as a specific treatment for systemic lupus erythematosus (SLE) in 2011. We present the experience with BLM in a Spanish cohort with more than 460 patients.ObjectivesTo describe demographic characteristics, efficacy and safety of BLM in patients with SLE in Spanish population since its approval.MethodsDescriptive, retrospective, multicenter study in patients diagnosed with SLE according to EULAR/ACR 2019, SLICC and/or ACR 1997 diagnostic criteria. Data regarding SLE patients treated with BLM were collected from medical records (2011-2022). Demographic features, efficacy, laboratory variables, SLEDAI, renal involvement, steroid dose, administration routes and safety were assessed. To see whether a trend in BLM prescription had changed or not over time, two periods of time were analyzed: 2011-2016 (period1) and 2017-2022 (period2).ResultsBaseline characteristics of patients are summarized in Table 1.A total of 462 patients (36 hospitals) were included, 50.9% were on intravenous (IV), 34% on subcutaneous (SC) and 15.1% switched from IV to SC route. The median number of pre-BLM csDMARD use was 2.0 (2.0-3.0), being hydroxychloroquine (HCQ) the most frequently used (94.5%). Fifty-two patients were treated with IV cyclophosphamide with a median of 6 bolus received. At the time of BLM start, 443 patients were on prednisone with a median dose of 6.2 mg (5.0-10.0). Significant decreases in prednisone dose, SLEDAI and anti-DNA antibodies were observed from baseline until the last visit, whereas complement C3 and C4 values raised (Figure 1). A total of 118 patients (27.4%) had renal involvement with a median proteinuria of 1.0 g/day (0.5-2.4). Renal biopsy was done in 102 out of 118 patients, being class IV (33%), class III (21%) and class V (16%) the most frequently reported. After BLM, 73.3% of these patients improved (median proteinuria of 0.2 g/day (0.1-0.7).In period1, 100 patients started BLM compared to 362 in period2. The median time from SLE diagnosis to BLM begin was 7.1 (4.0-13.7) and 6.2 (2.1 -14.4) years in period1 and period2, respectively (p=0.454). We found a trend to use more csDMARD before BLM treatment in period1: 2.5 (2-3) vs. 2 (2-3) (p=0.088).A total of 143 (30.5%) patients discontinued treatment mostly due to inefficacy (55.9%) and infections (11.9%). In fact, 116 patients developed infections, mostly mild;2 patients died, 16 had COVID-19 and 4 patients developed tumors requiring discontinuation of the drug.ConclusionIn our cohort of SLE patients in a real-world setting, BLM has been effective, safe and seems to be a good choice to treat renal involvement.References[1]Navarra SV, Guzmán RM, Gallacher AE, et al.

ABSTRACT
BackgroundSocial media platforms have become a vital resource for individuals seeking information and support regarding health issues, including rheumatoid arthritis (RA). As such, the content generated on these platforms represents a valuable source of data for gaining insight into patients' perspectives on RA. However, previous research in this area has primarily relied on qualitative analyses of small sample sizes, limiting the ability to extract meaningful insights from social media content related to RA. With the advancement of machine learning techniques, it is now possible to analyze and extract insights from large volumes of social media posts related to RA.ObjectivesThe purpose of this study was to identify the most common topics discussed in a large dataset of submissions about RA on Reddit, one of the world's largest online forums.MethodsThe data for this study was collected from the two largest Reddit forums ("subreddits”) dedicated to RA, r/rheumatoid arthritis and r/rheumatoid, which have 18.9k and 7.6k members respectively. We retrieved all submissions but excluded responses in our analyses. All deleted or duplicate submissions and those with fewer than 10 words were removed, retaining 11,094 submissions from over 5,000 users for the analysis. To identify common themes, we applied topic modeling, a technique in natural language processing that identifies underlying themes or topics in a collection of documents. We used the Bertopic Python package (Grootendorst, 2022), which employs deep learning techniques to perform the topic modeling.ResultsThe data indicates a significant increase in submissions to the two subreddits, rising from 113 in 2014 to 2892 in 2021 and 1928 in the first 8 months of 2022. Upon analysis, 65 topics were identified, with 4162 submissions (37.5%) remaining unclassified. A topic specifically dedicated to requests to participate in surveys was removed as it did not pertain to the experiences of forum users. Among the remaining topics, the top 10 accounted for 44.90% of all submissions. To better understand each topic, a sample of 10 submissions with the highest probability for that topic were examined (Table 1).Table 1.Top 10 most frequent topicsTopicn of submissionsShare of total*Side effects of methotrexate5268.02%COVID & vaccines4627.04%Mental health4386.68%RF and anti CCP test results3315.04%RA of friends, partners, and close relatives2623.99%Complaints about rheumatologist2123.23%Questions about Humira1882.87%Questions about prednisone1822.77%Diets and RA1752.67%Early symptoms of possible RA1702.59%Exercise and RA1682.56%* After excluding unclassified topicsThree of the ten topics pertained to specific medications - methotrexate, Humira, and prednisone, accounting for 12.71% of the total. The most prevalent topic, at 8.02%, focused on the side effects of methotrexate, with many submissions inquiring about symptoms such as nausea. The second most common topic, at 7.04%, primarily revolved around COVID-19 and related issues, with some pre-COVID vaccine discussions also included. In 2021, COVID-related discussions were the most prevalent topic. The third most frequent topic (6.68% of total), dealt with mental health and the emotional struggles faced by those living with RA.ConclusionThe surge in submissions on Reddit demonstrates its growing popularity as an online forum for discussing topics related to RA. Utilizing deep learning-based topic modeling has proven to be an effective method for extracting meaningful topics from the questions and experiences shared by users. The vast amount of data generated by Reddit, in combination with advanced machine learning techniques, enables both an overview of the various topics discussed and a detailed examination of specific topics. This makes the use of social media data a valuable source of insight into the concerns of RA platform users.Reference[1]Grootendorst, M. (2022).

ABSTRACT
Introduction: STAT1 gain-of-function (GOF) disease is associated with chronic mucocutaneous candidiasis (CMC) and a broad spectrum of infectious, inflammatory, and vascular manifestations. The Janus Kinase inhibitor ruxolitinib has been used successfully for CMC and autoimmune phenomena. We describe a case of warm autoimmune hemolytic anemia (WAIHA) in a patient with STAT1 GOF disease after initiating ruxolitinib. Case report: A 36-year-old man with STAT1 c.850G>A (p.Glu284Lys) mutation presented with CMC as well as recurrent viral and bacterial infections, lymphadenopathy, enteritis, nodular regenerative hyperplasia (NRH) and splenomegaly. Immune workup confirmed a combined immunodeficiency with hypogammaglobulinemia and T-cell lymphopenia. Ruxolitinib was initiated at 5 mg twice daily (due to pre-existing thrombocytopenia) with up titration over 3 months to 20 mg twice daily. He improved with weight gain, increased energy, resolution of chronic anemia, and improved lymphadenopathy and splenomegaly on imaging. Serum CXCL9 only minimally decreased from 4660 pg/ml to 3990 pg/ml. Soon after reaching ruxolitinib 20 mg twice daily, he developed JC viremia, prompting dose reduction to 15 mg BID. Within two weeks, he developed a non-COVID upper respiratory tract infection followed by fatigue, shortness of breath with ambulation, and dark urine. Emergency evaluation revealed warm antibody positive hemolytic anemia with a hemoglobin of 5 g/dL, and worsened thrombocytopenia. He was treated with blood transfusions, pulse steroids, and high-dose IVIG with stabilization but continued hemolysis. Due to the JC viremia, there was concern to give rituximab with increased PML risk. Bone marrow showed trilineage hematopoiesis, a mild increase in megakaryocytes and RBC precursors, and a loss of B-cell progenitors with retention of mature B cells. His B and T lymphocyte numbers had increased since prior to ruxolitinib, with a predominance of Tfh1-cells (58.7% of total Tfh-cells). He was started on sirolimus with a slow taper of prednisone with continued stable hemoglobin and platelets, and resolution of hemolysis after 3 months. Conclusion(s): To our knowledge, this is the first case of a STAT1 GOF patient developing WAIHA while receiving ruxolitinib therapy. Treatment choices were complicated by the risks of PML. Sirolimus combined with ruxolitinib allowed wean of corticosteroid and subsequent resolution of hemolysis.Copyright © 2023 Elsevier Inc.
ABSTRACT
BackgroundCOVID-19 vaccination campaigns successfully impacted on viral spreading and in particular on clinical course of the disease. However, secondary to a highly extended vaccination program, several local and systemic adverse events associated with mRNA COVID-19 vaccines have been reported. Pericarditis and myocarditis are examples of cardiac complications related to these vaccines. In particular, cases of pericarditis have occurred after mRNA COVID-19 vaccination (mostly secondary to vaccination with Moderna than Pfizer-BioNTech), especially in male adolescents and young adults, more often after the second dose. The incidence is approximately of 1-2 cases/100.000.ObjectivesAim of our study was to study the clinical profile of pericarditis occurred within 30 days after COVID-19 vaccines in our clinic.MethodsWe present a case series of patients who developed pericarditis after COVID-19 vaccination in the Department of Internal Medicine at Fatebenefratelli Hospital in Milan, followed from December 1, 2021 to April 15, 2022.ResultsTwenty-five individuals, of which 18 (72%) were women and 7 (28%) were males, had vaccine related pericarditis. Two patients were vaccinated with AstraZeneca, 2 with Moderna, the remaining with Pfizer-BioNTech. Median age was of 42 years. Of all patients, one subject was affected by constrictive effusive pericarditis, while another required treatment of pericarditis with Anakinra, switched to Canakinumab after severe skin reactions, because of failure of therapeutic response to first-line treatments.Two patients required hospital admission, in one case for a transient constrictive pericarditis. In the remaining cases clinical symptoms associated with post-vaccines pericarditis were mild and didn't require hospitalization.Chest pain was reported in 100% of cases, whereas pericardial effusion (in one case larger than 10 mm) was evidenced in 30% of subjects. Eighty percent of patients experienced tachycardia, whereas 90% reported asthenia.An increase in indices of inflammation (CRP) was documented in 50% of patients, usually mild.With regard to therapy, 90% of patients were treated with NSAIDs, 95% with colchicine, while 50% of cases required treatment with low-dose steroids.ConclusionCOVID-19 vaccination induces a particular form of pericarditis, often insidious and very troublesome, but with good prognosis. The clinical phenotype showed less typical chest pain, often normal indices of inflammation and little or no instrumental changes, but patients often experimented tachycardia and functional limitation. With regard to therapy, we used NSAIDs at adequate dosages to control the clinical condition, or low-dose colchicine. Low doses of cortisone (e.g., prednisone 5-10 mg a day) were useful in the presence of marked asthenia or systemic symptoms. Beta-blockers or ivabradine were used in the presence of tachycardia.References[1]Barda N, Children 2021, 8(7), 607;Safety of the BNT162b2 mRNA Covid-19 in a Nationwide setting.

ABSTRACT
BackgroundTreatment with Rituximab (RTX) in patients with rheumatic diseases (RD) has presented a challenge during the COVID-19 pandemic, as RTX leads to markedly reduced and often undetectable antibody responses after COVID-19 vaccination (1).ObjectivesTo investigate the effect of COVID-19 mRNA revaccination (two doses) on the antibody response in patients with RD who were initial vaccine non-responders. Further, to examine if B-cell levels or T-cell responses before revaccination predicted seroconversion.MethodsFrom a RD cohort (COPANARD) vaccinated with the standard two-dose COVID-19 vaccinations, we enrolled cases without detectable antibody responses (n=17) and controls with detectable antibody response (n=29). Blood donors (n=32) were included as additional controls. Samples were collected before and six weeks after completed revaccination. Total antibodies (abs) and specific IgG, IgA, and IgM against SARS-CoV-2 spike protein, SARS-CoV-2 neutralizing abs, and SARS-CoV-2 reacting CD4+ and CD8+ T-cells were measured before and after revaccination. B-cells (CD19+CD45+) were quantified before revaccination. This study was funded by the Danish Rheumatism Association.ResultsPatient demographics are given in Table 1. Forty-seven percent of cases had detectable total SARS-CoV-2 abs and neutralizing abs after revaccination. However, antibody levels were significantly lower than in controls and blood donors (p<0.008), Figure 1A+B. Revaccination induced an antibody class switch in cases with a decrease in detectable IgM abs (Baseline 11/17, Followup 3/17) and increase in IgG. No significant difference was observed in T-cell responses before and after revaccination between the three groups, Figure 1C. The proportion of cases with detectable CD4+ T cells increased from 69% to 88% (p=0.25), and for CD8+ T cells, the proportion decreased from 88% to 82% (p=1.00). Only 29% of cases had measurable B-cells compared to 100% of controls and blood donors, Figure 1D. Fifty percent of revaccinated cases who seroconverted had measurable B-cells before revaccination, Figure 1D.Univariate logistic regression analysis was performed to analyze if active RTX treatment, the presence of B-cells, or a positive T-cell response prior to revaccination predicted seroconversion of total SARS-CoV-2-abs in the patient cohort. We did not find a significant explanatory effect of either variable in the univariate logistic models, data not shown.Table 1.DemographicsCases Revaccination, n=17Controls Boost, n=29Female sex, no(%)1482%2172%Age, median (IQR)6549 - 706762 - 72Disease duration, years1510 - 18229 - 31Rheumatoid Arthritis/SLE13/410/19None DMARD529%828%Prednisone424%13%Methotrexate741%1241%Hydroxychloroquine212%414%None biologic treatment424%931%Rituximab1271%0TNF-inhibitors16%724%JAK-inhibitors0621%IL-6-inhibitors, Abatacept, Benlysta0724%Previous rituximab treatmentAny rituximab treatment1694%13%RTX within the last 15 months, no1488%0Cumulative total dose, mg134-242Time from RTX to revaccination, months95-1249Figure 1.ConclusionIn conclusion, forty-seven percent of initial non-responders were able to seroconvert after two-dose revaccination. However, plasma concentrations of the antibodies against SARS-COV-2 and the levels of neutralizing capacity remained significantly lower than in immunocompetent blood donors. B-cell levels or T-cell responses before revaccination did not predict seroconversion. Our study suggests that patients with RDs who did not mount a detectable serological response to a COVID-19 mRNA vaccine have a T cell response similar to immunocompetent controls. Future studies should establish the antibody levels that identify RD patients without sufficient protection against SARS-CoV-2 infection.References[1]Troldborg A, et al.

ABSTRACT
Objectives: To assess the impact of COVID-19 on disease activity and severity outcomes in patients with systemic vasculitis. Method(s): The Reuma-CoV Brazil is a longitudinal, multi-stage cohort study, designed to monitor patients with immune-mediated rheumatologic disease (IMRD) during the SARS-CoV-2 pandemic. Systemic vasculitis patients with COVID-19 were compared with those without COVID-19. Vasculitis activity was evaluated by the patient global assessment (PGA) and Birmingham Vasculitis Activity Score 3 (BVAS 3). The prognosis was assessed by the Five-Factor Score (FFS). Result(s): Between May 2020 and January 2021, 53 patients with vasculitis were included and followed for six months, 32 (60.3%) with COVID-19 and 21 (39.6%) in the control group. In total, 79.5% were female with a mean age (SD) of 49 (16.5) years. Both groups were homogeneous regarding sex, age, and comorbidities. Thirty-eight (71.8%) patients had at least one comorbidity. Thirty-two patients were classified as small vessels vasculitis (SVV), 10 as large vessels (LVV) and 11 as vasculitis of variable caliber. There was no difference in PGA, BVAS and FFS when comparing before and after SARSCoV-2 infection (Table 1). In the group of patients with LVV, two had clinical or laboratory worsening post infection. Compared to controls, patients with vasculitis and COVID-19 were at higher risk of intensive care unit (ICU) hospitalization [OR (IC95%) = 7.98 (3.78 - 16.8), p alpha 0.001], mechanical ventilation [OR (IC95%) = 7.45 (3.16 - 17.5), p = alpha0,001] and death [OR (IC95%) = 9.69 (3.87 - 24.3), p alpha 0,001]. Of the 7 patients who died, 40%were using high-dose prednisone (>20 mg/d) and 38.8% were using rituximab. Conclusion(s): In this sample of patients with systemic vasculitis, there was no worsening of disease activity after COVID-19, but there was a higher risk of poor outcomes, possibly related to immunosuppression.
ABSTRACT
Objectives: To evaluate the humoral immune response to the third dose (booster) of vaccine against SARS-CoV-2 in patients with autoimmune rheumatic diseases who were seronegative after a two-dose regimen. Method(s): Observational study. Patients with autoimmune rheumatic diseases who had not achieved seroconversion after a two-dose vaccine schedule against SARS-CoV-2 were included. To assess the humoral immune response, anti-RBD IgG (S protein receptor binding domain) neutralizing antibody titers were determined by ELISA (cutoff titer 200). The determination was made between 30 to 45 days after the third dose. Result(s): From 66 patients who received SARS-CoV-2 vaccination, 18 patients (29.5%) were seronegative after a two-dose schedule. 61% had SLE, 77% had comorbidities (61% with hypertension, p = 0.03). Patients were on treatment: 10 with prednisone (8 with doses greater than 10 mg/d, p = 0.01), 10 with hydroxychloroquine, one with methotrexate, one with leflunomide, four with azathioprine, five with my cophenolatemofetil and five with rituximab (they are the total number of non-responders on biological treatment, p = 0.03). Regarding the primary vaccination regimen, 11 received BBIBP-CorV (p = 0.01), 5 AZD1222, 1 Gam-COVID-Vac and 1 mRNA1273/Gam-COVID-Vac heterologous scheme. Of these 18 non-responders, 14 received a third dose;nine patients (62%) presented anti-RBD IgG detectable. Of the five patients who did not respond to the booster vaccination, three had received BBIBP-CorV as the initial schedule and the vaccines applied as a third dose were Ad5-nCoV (1), BNT162b2 (1), AZD 1222 (2) and Gam-COVID-Vac (1). They were being treated with: rituximab (2), azathioprine (2) and mycophenolate mofetil (1). Treatment with higher doses of prednisone was the only factor associated with non-seroconversion to the third dose (8 +/- 4.5;p 0.02). Conclusion(s): The third dose of SARS-CoV-2 vaccine allowed to improve the serological response to vaccination, achieving a seroconversion of 62% in this group of patients.
ABSTRACT
Introduction: Crohn's disease (CD) and ulcerative colitis (UC) can be difficult to manage and, due to a lack of meaningful quality measures, patient (pt) care may vary by provider. To understand where gaps in care may exist for these pts, this study assessed specific healthcare resource utilization (HRU) and medication metrics that may be potential quality of care (QOC) indicators. Method(s): Using a large commercial US claims database (2019-2020), pts with CD or UC were identified. Potential QOC indicators were selected based on clinical guidelines and recommendations from measures of quality organizations and included CD or UC prevalence;gastroenterologist (GE) and IBD-related non-GE outpatient visits;IBD-related emergency department visits or hospitalizations;excessive steroid use (prednisone equivalent >=10 mg/day for >=60 consecutive days or a single prescription of >=600 mg prednisone);excessive steroid users on corticosteroid (CS)-sparing therapy;excessive steroid users with central dual-energy X-ray absorptiometry (DEXA) or osteoporosis pharmacologic treatment;use of targeted immunomodulators (TIMs) and oral mesalamine (CD only);imaging assessments;and assessment of inflammatory biomarkers. National percentages of pts achieving each metric are reported. Result(s): In total, 41,555 CD and 52,507 UC pts were identified in 2019, resulting in a 0.3% and 0.4% prevalence, respectively (Table). Over a third of CD pts (39.8%) and almost half of UC pts (45.5%) did not visit a GE in 2019. Around 10% CD pts, and up to 6.4% of UC pts, had IBD-related ED visits or hospitalizations. 17.1% CD and 14.5% UC pts were excessive steroid users, yet < 9% CD and UC pts, received DEXA scans and/or bone treatments. A third of excessive steroid users with CD (34.5%), and over half (53.0%) of those with UC, did not receive CS-sparing therapy. The rate of TIM use was over two times higher in CD vs UC pts (CD: 44.3%;UC: 18.9%). Despite evidence that mesalamine is ineffective in CD, 18.7% of pts with CD were prescribed it. Inflammatory biomarker level testing rates were < 50% in both CD and UC. Similar outcomes were reported in 2020, with lower HRU, possibly due to COVID-19. Conclusion(s): This analysis of QOC indicators highlights various areas for improvement that may provide better treatment outcomes and reduce HRU for pts with CD and UC. Future research is needed to assess outcomes in pts that are not being routinely monitored. (Table Presented).
ABSTRACT
Introduction: Nirmatrelvir/ritonavir is a new medication approved for the treatment of COVID-19 infection. It prevents viral replication by inhibiting the SARS-CoV-2 main protease. While mild adverse effects were described, including dysgeusia, diarrhea, hypertension and myalgia1, there were no reported cases of pancreatitis. Case Description/Methods: An 81-year-old female with a past medical history of hypertension and COPD presented to the hospital complaining of abdominal pain and nausea for one day. She had no history of alcohol, tobacco or marijuana use, recent travel, or trauma. Her medications included lisinopril and prednisone, and she had completed a 5-day course of nirmatrelvir/ritonavir for the treatment of COVID-19 infection 2 days prior to presentation. On abdominal exam, she had left upper and lower quadrant tenderness. Blood tests revealed an amylase of 1333 U/L, lipase of 3779 U/L, triglycerides of 297 mg/dL and calcium of 8.7 mg/dL. CT scan revealed an indurated pancreatic body and tail with peripancreatic fluid along the paracolic gutter. Ultrasound of the abdomen and MRCP did not reveal any acute findings. IgG subclasses 1-4 were normal. Discussion(s): According to the revised Atlanta criteria, the patient had clinical findings consistent with acute pancreatitis. Common causes such as gallstone, alcohol, autoimmune and hypertriglyceridemiainduced pancreatitis were ruled out. There were no masses or structural abnormalities on imaging that might have explained her diagnosis. There have been at least 2 reported cases of lisinopril and prednisone induced pancreatitis, however according to Badalov et al.2 both of these medications are class III drugs that lack any rechallenge in the literature. Moreover, the patient had been taking these medications for many years, making them an unlikely cause of the presenting diagnosis. There are no reports of nirmatrelvir/ritonavir associated pancreatitis or known pharmacologic interaction with her home medications, and a meta-analysis conducted by Babajide et al. revealed no association between acute pancreatitis and COVID-19 infection (3). Given the negative findings stated above and the recent initiation of a new medication, nirmatrelvir/ritonavir was the likely cause of acute pancreatitis.
ABSTRACT
Introduction: Mucosa-associated lymphoid tissue (MALT) lymphomas are extra-nodal marginal zone B-cell lymphomas, most commonly found in the stomach, associated with Helicobacter pylori infections, and generally not linked with inflammatory bowel disease. Rectal MALT lymphoma is very uncommon and often associated with painful defecation, change in bowel habits, or rectal pressure/prolapse. Here, we present a rare case of an asymptomatic female with ulcerative colitis (UC) found to have benign-appearing rectal polyps during a routine screening colonoscopy. Case Description/Methods: The patient is a 56-year-old female with a history of left-sided UC, diagnosed in 1993, with one flare after receiving the 2nd dose of the Moderna COVID-19 vaccine, taking oral Olsalazine 500 mg twice daily, low-dose Prednisone, and mesalamine suppositories as needed presenting for screening colonoscopy. The patient was asymptomatic, citing regular non-bloody bowel movements and normal stool consistency. Colonoscopy revealed two 7 mm sessile, non-bleeding rectal polyps, surrounded by congested, erythematous, friable, and ulcerated mucosa in the rectosigmoid colon. Cold forceps biopsies were taken. Hematopathology evaluation of the routine colon biopsy samples revealed chronic nonspecific colitis while pathology of the rectal polyps showed marked lymphoplasmacytic infiltrate and extra-nodal marginal zone lymphoma of MALT. Ancillary studies, immunohistochemistry, and molecular studies for B-cell gene rearrangement confirmed extra-nodal marginal zone lymphoma of MALT with prominent plasmacytic differentiation. The patient was informed and close follow-up in Gastroenterology clinic was arranged. (Figure) Discussion: Rectal MALT lymphoma is rare with unclear management options. Treatments of UC include watchful waiting, surgical resection, endoscopic mucosal resection, radiation, and/or chemotherapy. Helicobacter pylori infections, though strongly linked with gastric MALT lymphoma, have not been shown to be strongly correlated with rectal MALT lymphoma. Given that patients with UC have chronic UCassociated colonic inflammation, lymphoma is often difficult to distinguish visually during colonoscopy, frequently masked by ulcerations and pseudo-polyps. In cases like these, more definitive treatments such as surgical resection could therefore be warranted. Long-term follow-up data is sparse and definitive management remains a clinical conundrum, thus these patients require reliable long-term multidisciplinary close follow-up. (Figure Presented).
ABSTRACT
Background: Tixagevimab(Txg)/cilgavimab (Cgv) was given emergency use authorization (EUA) to provide passive immunity against COVID-19(CoV) for immunocompromised (IC) pts who may not mount an adequate response to CoV vaccination [1]. Recipients of allogeneic hematopoietic cell transplant (Allo-HCT) are amongst the most IC. Due to high risk of mortality and complications of CoV in this population, Txg/ Cgv was used as pre-exposure prophylaxis (PrEP) under EUA without prior study. Our study aims to assess efficacy and adverse events (AE) of Txg/Cgv administration in this cohort of patients to help guide future practice. Method(s): We retrospectively investigated Allo-HCT recipients who received Txg/Cgv as PrEP. Data were gathered including changes in blood counts, incidence of graft-vs-host-disease (GVHD), history of prior CoV infection and vaccination status. Pts who developed CoV infection after PrEP were assessed for supplemental oxygen(O2) need and hospitalization. Data cutoff date was 9/30/2022. Result(s): A total of 18 Allo-HCT recipients received Txg/Cgv. Table 1 summarizes patient and transplant characteristics. Thirteen (72.2%) pts received 2 doses of 150mg of Txg / Cgv, while 4 pts received 1 dose of 300mg, and one patient received one dose of 150mg. Median time to first dose was 213 days [range 22-3660] post-transplant. Two pts had lab confirmed CoV, one at 24 days post dosing and the 2nd patient at 22 days post dose. Neither required supplemental O2;one was hospitalized for fever. Prior to dosing, 44.4% (8/18) of pts had GVHD. (Table Presented) (Figure Presented) (Figure Presented) Of these, 62.5% (5/8) had no changes in the severity of their GVHD. Two of 8 (25%) pts with pre-existing chronic GVHD had a flare of symptoms. Two (25%) had improvement of GVHD. Two pts developed new onset acute GVHD following Txg/Cgv administration, one requiring 1mg/kg prednisone and the other topical steroids (2/18, 11%). Figure 1 summarizes GVHD patterns observed. Hematologic parameters did not change significantly, see Figure 2. None of the pts reported any subjective AE following dosing. Summary: Txg/Cgv was found to be safe and effective for Allo-HCT pts, without significant toxicity. Two patients had new onset GVHD and 2 patients had progressive GVHD. Whether there is a true association between Txg/Cgv and development of GVHD should be investigated in a larger cohort and then investigated for possible underlying mechanisms.Copyright © 2023 American Society for Transplantation and Cellular Therapy
ABSTRACT
Purpose of study A 32-years old male with known multi-system sarcoidosis in remission for 5 years off treatment presented to the emergency room with complaints of generalized weakness, hematemesis, epistaxis, and bruises. Physical examination was notable for petechiae, ecchymosis along with papules and plaques suggestive of active sarcoid skin lesions on his extremities. Laboratory workup was significant for thrombocytopenia 3000/uL, acute kidney injury with sub-nephrotic proteinuria. Peripheral blood smear did not show evidence of hemolysis and direct Coombs test was negative. Infectious workup including COVID-19, HIV, and hepatitis serologies were negative. Computed Tomography (CT) of chest, abdomen, and pelvis showed mild splenomegaly and an increased number of sub-centimeter hilar and mediastinal lymph nodes. The patient was treated with dexamethasone 40 mg daily for 4 days and intravenousimmunoglobulins (IVIG-2 gm/kg) for possible Immune Thrombocytopenic Purpura (ITP) with improvement in platelet count to 42000/uL by day 3. His workup for AKI and sub-nephrotic proteinuria was negative apart from a positive ANA (1: 160) with low complements. The anti-phospholipid antibody panel was negative. The ACE level was markedly elevated (>80U/L). The patient could not get a renal biopsy due to severe thrombocytopenia. He was discharged but was re-admitted in 15 days for severe thrombocytopenia of 1000/uL, epistaxis, and bruising. We continued high dose steroids along with IVIG 1 gm/kg for refractory ITP with minimal response and started anti-CD20 agent (Rituximab) 375 mg/m2 weekly with thrombopoietin-receptor agonist (Eltrombopag). His platelets count improved in response to treatment and subsequent renal biopsy showed focal and segmental glomerulosclerosis along with mild interstitial fibrosis, tubular atrophy thought to be from long standing sarcoidosis. There was also evidence of focal arteriosclerosis with no evidence of granulomas, immune complex, complement, or IgG4 deposition. Given skin lesions, thrombocytopenia, extensive lymphadenopathy, and renal involvement with markedly elevated ACE levels the overall picture was consistent with active multi-system sarcoidosis. His platelet count increased to 177,000/uL at the time of discharge. Currently, the patient is on slow steroid taper along with Eltrombopag 25 mg every other day without any recurrence of his symptoms so far. Methods used We described one case of sarcoidosis with hematologic and renal involvement. Summary of results Our patient developed hematologic and renal complications approximately 6 years after being diagnosed with sarcoidosis. Initially, he did not demonstrate sufficient clinical response to IVIG and high dose steroids. However, after a course of anti-CD20 agent (Rituximab) and with the addition of thrombopoietin-receptor agonist (Eltrombopag) he showed improvement of platelet count and stabilization of the renal function. Currently, the patient is receiving maintenance therapy with Prednisone 7.5 mg daily along with Eltrombopag 25 mg twice weekly with no recurrence of ITP and stable renal function. A further decision on whether the patient needs another cycle of Rituximab will be determined by the patient's clinical course. Conclusions Highly variable manifestations of Sarcoidosis can pose a significant diagnostic and therapeutic challenge as can be seen from our case. ITP is a rare hematological manifestation of sarcoidosis and addition of anti-CD20 agents should be considered in refractory cases.
ABSTRACT
The lung is the most common organ affected by sarcoidosis. Multiple tools are available to assist clinicians in assessing lung disease activity and in excluding alternative causes of respiratory symptoms. Improving outcomes in pulmonary sarcoidosis should focus on preventing disease progression and disability, and preserving quality of life, in addition to timely identification and management of complications like fibrotic pulmonary sarcoidosis. While steroids continue to be first-line therapy, other therapies with fewer long-term side-effects are available and should be considered in certain circumstances. Knowledge of common clinical features of pulmonary sarcoidosis and specific pulmonary sarcoidosis phenotypes is important for identifying patients who are more likely to benefit from treatment.Copyright © ERS 2022.
ABSTRACT
BACKGROUND: The novel SARS-CoV-2 Coronavirus pandemic has had significant global impact on health care. The pandemic's effect on patients with inflammatory bowel disease (IBD) is unknown, and health care delivery to this largely immunocompromised population is of concern, as many patients refrained or were unable to seek in-person medical care. We noticed there was a decrease in IBD related Emergency Department (ED) visits. Thus, we aimed to explore if the pandemic influenced IBD specific search trends in the United States. We predicted more patients would search for symptoms or medications using Google in order to self-treat or self-care. METHOD(S): Using Google Trends (GT), we queried Crohn's Disease (CD) or Ulcerative Colitis (UC) in combination with IBD-related symptoms (i.e. bloating, rectal bleeding, abdominal pain and diarrhea) or medications (i.e. infliximab and prednisone) between January 1 and April 30 for the years 2018-2020 in the United States. Frequencies of the specific search terms were compared to the site's relative search volume over weekly and monthly intervals. IBD related ED visits were also collected from July 2018 to July 2020. Data was analyzed using monthly and weekly mean search scores compared across years and through 2020 using ANOVA with post-hoc Tukey adjustment for multiple comparisons. RESULT(S): There were decreased search scores for bloating and rectal bleeding with IBD terms occurring during March and April of 2020 compared to years prior but not abdominal pain or diarrhea. The bloating plus CD/UC queries saw the largest variation in 2020 (CD: F = 19.18 with (2,89) df, P < 0.0001, UC: F = 14.08 with (2,89) df, P < 0.0001). For April 2020, medication search terms for infliximab + UC were significantly decreased (F = 47.73 with (2,89) df, P < 0.0001) but not for infliximab + CD (F = 3.08 with (2,89) df, P = 0.051) Prednisone searches also significantly decreased with CD and UC during this time period. In terms of IBD related ER visits, there were 84 in 2018, 99 in 2019, and 15 in 2020. The average quarterly visits in the 30 months preceding Covid was 22.5, while there was only one visit in quarter two of 2020. From March 2020 to July 2020 there were only 4 ED visits total. CONCLUSION(S): Assuming the global pandemic was the main influence of GT during March and April 2020, it appears that some IBD-related searches were significantly reduced compared to pre-pandemic levels, while others did not change. It is possible that patients utilized other services like patient portals and telehealth to communicate with providers instead of Google searches. Interestingly, IBD related ED visits were reduced during the peak of the pandemic, which raises the question and concern of how IBD patients managed their disease during this time. Limitations include the non-specificity of querying a search engine which may not reflect the habits of confirmed diagnosed IBD patients. Further research should investigate how patients cared for themselves during the pandemic. It will be important to continue to monitor the trends of IBD patient utilization of the healthcare system as cities and IBD centers start to reopen to safely and effectively deliver care.
ABSTRACT
Case Report: A 26-year-old woman with a history of warm autoimmune hemolytic anemia, immune thrombocytopenia, triple positive antiphospholipid syndrome, and chronic migraine presented to the emergency department with worsening generalized fatigue for one week associated with headache, dyspnea on exertion, nausea, vomiting and lightheadedness. Of note, she had received her second dose of mRNA COVID-19 vaccine 4 days prior to presentation. On admission, patient was found to be severely anemic with a hemoglobin of 4.3g/dL which is decreased from her baseline hemoglobin of 9-10.5g/dL;however, W-AIHA precluded the administration of blood product until adequate blood with the appropriate antibodies could be acquired. During the hospitalization, hemoglobin decreased to 3.3g/dL. Patient was then administered the most compatible blood product which she tolerated well. Hematology was consulted who started the patient on hydroxychloroquine, high dose methylprednisolone, and Intravenous Immunoglobulin (IVIG). Throughout the admission, the patient remained asymptomatic. After 2 days of IVIG, three days of high dose glucocorticoids, and one unit of packed red blood cells, the patient's hemoglobin increased to 7.2g/dL. Patient was discharged home on prednisone taper and hydroxychloroquine. Conclusion(s): Episodes of hemolytic anemia after either the first or second dose of mRNA COVID vaccines are rare and have occurred in patients with known hematological pathology as well as patients without any history of hematologic or immunologic disorders. When taking the history of patients presenting with hemolytic anemia, it is important to query recent vaccinations as, while rare, mRNA COVID vaccine may well be the etiology. While this ultimately will likely not change patient management, this information would be beneficial for further study.
