ABSTRACT
BackgroundGCA is a critically ischemic large vessel vasculitis, varying in extent, severity and outcomes, hence requires disease stratification using clinical, laboratory and imaging parameters, for targeted management. Although DMARDs are used, the effectiveness in real life, such adjuvants remain un-elucidated. We performed a prospective, multi centre cohort study of new GCA stratified into remitting, relapsing, refractory, ischemic disease.ObjectivesWe assessed prognostic factors and compared critical outcomes such as remission with glucocorticoid (GC) monotherapy versus GC plus DMARDs in the first 12 months.MethodsHAS GCA study (1) recruited consecutive patients with new onset GCA from 7 centres (UK, Italy, Spain, Netherlands). diagnosis was confirmed used a modified GiACTA criteria at 6 months follow up. All underwent ultrasound (bilateral common, parietal, frontal temporal arteries, and axillary arteries) using accepted standard cut-off values [2]. GCA patients had US at baseline,1,3,6,12 months and halo count (HC) and Halo score (Temporal TAHS, axillary AAHS, total THS) assessed [3]. The primary outcome- remission at 12 months (absence of signs/symptoms, CRP<5 mg/dl, prednisolone < 5 mg daily). Results are reported as descriptive statistics.Results229 participants included in the study (GCA- 84 (36.68 %) (Figure 1). Study recruited during Covid pandemic,73 completed,11 lost to follow-up (died -7, withdrawn-4). The deceased/withdrawn patients (compared to completers) were older (80 v74 yrs, p=0.018), preponderantly male (73% v 36%, p=0.043) with visual symptoms (91% v 49%, p=0.010) partial/total sight loss (55% v 21%, p=0.024), lower CRP (21 v 68, p=0.061) and ESR (42 v 62, p= 0.317).Of 73 completers 36 required early DMARDs (<12 weeks) for refractory/relapsing/ischemic/GC related AEs. This group had more LV involvement (50% v 11%, p=0.0003), Remission attained at 12 months 32/36 (89%) in DMARD group was comparable to the remitting GC monotherapy group 33/37 (89%) with comparable cumulative GC doses (Figure 1, Table 1).At 12-months follow up, median TAHS, AAHS and THS reduced from 13 to 3, 12 to 9 and 21.5 to 12, respectively.ConclusionOur study suggests, elderly males with visual symptoms, sight loss, lower CRP are a high-risk group with increased mortality within GCA. Difficult to treat disease is seen in half of all patients especially with LV involvement. This group responds well to early DMARD use achieving remission comparable to the remitting group at 12 months. Current therapies fail to achieve remission in 9.5 % of cases. HS and HC show significant improvement mirroring clinical outcomes during first 12 months of therapy.References[1]Sebastian A et al. BMC Rheum. 2020[2]Schafer VS et al.

ABSTRACT
Background: Patients with autoimmune systemic diseases (ASDs) can be counted among frail populations as regards the predisposition to COVID-19 due to the frequent visceral organ involvement and comorbidities, as well as the ongoing immunomodulating treatments. Objectives: Our long-term multicenter telephone survey prospectively investigated the prevalence, prognostic factors, and outcomes of COVID-19 in Italian ASD patients during the frst 3 pandemic waves. Methods: A large series of 3,918 ASD patients (815 M, 3103 F;mean age 59±12SD years) was consecutively recruited at the 36 referral centers of COVID-19 & ASD Italian Study Group. In particular, ASD series encompassed the following conditions: rheumatoid arthritis (n: 981), psoriatic arthritis (n: 471), ankylosing spondylitis (n: 159), systemic sclerosis (n: 1,738), systemic lupus (172), systemic vasculitis (n: 219), and a miscellany of other ASDs (n: 178). The development of COVID-19 was recorded by means of telephone survey using standardized symptom-assessment questionnaire (1). Results: A signifcantly increased prevalence of COVID-19 (8.37% vs 6.49%;p<0.0001) was observed in our ASD patients, while the cumulative death rate revealed statistically comparable to the Italian general population (3.65% vs 2.95%;p: ns). In particular, among the 328 ASD patients complicated by COVID-19, 57 (17%) needed hospitalization, while mild-moderate manifestations were observed in the large majority of individuals (83%). In addition, 12/57 hospitalized patients died due to severe interstitial pneumonia and/or cardiovascular manifestations. Interestingly, a signifcantly higher COVID-19-related death rate was observed in systemic sclerosis patients compared to the Italian general population (6.29% vs 2.95%;p=0.018). Other adverse prognostic factors to develop COVID-19 were the patients' older age, male gender, pre-existing ASD-related interstitial lung involvement, and chronic steroid treatment. Conversely, patients treated with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) showed a signifcantly lower prevalence of COVID-19 compared to those without (3.58% vs 46.99%;p=0.000), as well as the chronic administration of low dose aspirin in a subgroup of SSc patients (with 5.57% vs without 27.84%;p=0.000). Conclusion: The cumulative impact of COVID-19 on ASD patients after the frst 3 pandemic waves revealed less severe than that observed during the frst phase of pandemic (1), especially with regards to the death rate that was comparable to the Italian general population in spite of the increased prevalence of complicating COVID-19 in the same ASD series. Ongoing long-term treatments, mainly csDMARDs, might usefully contribute to generally positive outcomes of in this frail patients' population. Of note, a signifcantly increased COVID-19-related mortality was recorded in only SSc patients' subgroup, possibly favored by pre-existing lung fbrosis. Among different ASD, SSc deserves special attention, since it shares the main pathological alterations with COVID-19, namely the interstitial lung involvement and the endothelial injury responsible for diffuse microangiopathy. Besides SSc, the patients' subgroups characterized by older age, chronic steroid treatment, pre-existing interstitial lung disease, and/or impaired COVID-19 vaccine response (1-3), may deserve well-designed prevention and management strategies.
ABSTRACT
Background: Mixed cryoglobulinaemic vasculitis (MCV) is an immune-complex-mediated systemic vasculitis characterized by heterogeneous clinical manifestations mainly involving skin, kidney and peripheral nervous system. Despite reassuring safety data from EULAR Coronavirus Vaccine (COVAX) physician-reported registry, a signifcant proportion of patients with autoimmune diseases reported unwillingness to get vaccinated against SARS-CoV-2 infection in the preliminary results of the COVAD study, due to concerns about the lack of longterm safety data, and fear of associated side effects and disease fare. Objectives: Aims of this multicentre Italian study were to investigate the prevalence of vaccination against SARS-CoV-2 in Italian population of MCV patients, to explore the reason for the missed vaccination, and to investigate short and long-term side effects of the vaccine, including vasculitis fare. Methods: All MCV patients referring to 12 Italian centres were investigated about vaccination and possible both short-(within 48 hours) and long-term (within 30 days) adverse events (AE), classifed according to FDA Toxicity Grading Scale for preventive vaccine clinical trials, and possible disease fares. Patients with MCV related to lymphoproliferative disorders or connective tissue diseases were excluded from the study. The baseline variables were expressed as percentages or mean±standard deviation. The differences between continuous variables were analysed using the Mann-Whitney nonparametric test. The chi-squared test, or Fischer's exact when appropriate, were used for categorical variables (absolute numbers and percentages) regarding baseline characteristics. Results: A total of 416 patients, 69.2% females and 30.8% males, with a mean age of 70.4±11.7 years, were included in the study. Only 7.7% of patients were not vaccinated, mainly for fear of adverse events (50%) or for medical decision (18.8%). Corminaty was the vaccine most frequently used (80.5%). Interestingly, 6 patients (1.44%) were with a heterologous vaccination (usually AstraZeneca-Corminaty). Considering ongoing treatment, not vaccinated subjects were more frequently treated with chronic glucocorticoid therapy and/or Rituximab (p=0.049 and p=0.043 respectively). AE were recorded in 31.7% of cases, mainly mild and self-limiting (grade 1). More severe adverse events, such as fare of vasculitis, were observed in 5.3% of cases. AE were not associated with the kind of vaccine used and with the clinical manifestations of vasculitis. Patients with active MCV showed a lower frequency of short-term (within 48 hours) adverse events, but patients affected by peripheral neuropathies or skin vasculitis frequently showed a fare of their symptoms, recorded in 40% and 25% of cases, respectively. Finally, patients under glucocorticoid treatment were more prone to develop a vasculitis fare within a month after vaccination. Conclusion: Vaccination in MCV patients has been performed in a high percentage of patients showing a good safety. Other than patients' fear, treatments with rituximab and glucocorticoids are the main reasons for delaying vaccination, and it should be considered by the physician before starting therapy. Vasculitis fares were observed in about 5% of cases, in line with that observed in other autoimmune diseases. Specific attention should be reserved to people with purpura or peripheral neuropathy, for the increased risk of exacerbation of their symptoms.
ABSTRACT
Background: Pulse glucocorticoid therapy (> 250 mg of prednisone equivalent per day for 1 or a few days) is used in many immuno-inflammatory diseases for its quick and strong anti-inflammatory effect in emergency situations. It was used during in Severe Acute Respiratory Syndrome epidemics with no consistent data regarding its benefits. The efficacy and safety of this therapy associated to dexamethasone in coronavirus disease 2019 (Covid-19) pneumonia are unclear. Methods: We conducted a double-blind, randomized, placebo-controlled trial in hospitalized patients with COVID19-pneumonia. The study population included patients hospitalized for recent-onset Covid-19 pneumonia requiring supplemental oxygen in any delivery mode, except invasive mechanical ventilation, with PaO2/FiO2 between 100 and 300, and a C-reactive protein greater than 5 mg/dl. Patients were randomly assigned to receive 1 gram of methylprednisolone for 3 consecutive days or placebo in addition to standard dexamethasone. The primary outcome was the duration of the patient hospitalization, calculated as the time interval between randomization and hospital discharge without the need of supplementary oxygen. All-cause mortality, survival free from invasive ventilation and safety were also evaluated. Written informed consent was obtained from each patient or from the patient's legally authorized representative if the patient was unable to provide consent. Results: A total of 304 patients underwent randomization in 19 Italian sites between December 21, 2020, and March 10, 2021. Three patients retired the consent to the study one day after randomization, leaving 301 patients eligible for intention to treat analyses. 112 of 151 (74.2%) patients in the pulse methylprednisolone arm and 111 of 150 (74.0%) patients in the placebo arm were discharged from hospital without oxygen (p = 0.528) within 28 days from randomization. We did not observe any significant differences between pulse methylprednisolone and placebo arms in terms of admission to Intensive Care Unit with orotracheal intubation or death (19.9% versus 16.0% respectively;hazard ratio, 1.27;95%CI, 0.74-2.16), or in terms of overall mortality (9.3% versus 11.3% respectively;hazard ratio, 0.82;95%CI, 0.40-1.66). Serious adverse events occurred in 9 patients (6.0%) in the methylprednisolone pulse group and in 12 patients (8.0%) in the placebo group. Conclusion: Methylprednisolone pulse therapy in addition to dexamethasone was not of benefit in patients with COVID-19 pneumonia.
ABSTRACT
Objective: Chloroquine (CLQ)/hydroxychloroquine (HCQ) are two of the most studied drugs for the treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. There are very limited data on the effect of treatment of patients affected by rheumatic diseases with HCQ/CLQ and other conventional disease-modifying anti-rheumatic drugs (cDMARDs) on COVID-19. The aim of this study is to investigate the hypothesis that treatment of rheumatic diseases with hydroxychloroquine (HCQ)/chloroquine (CLQ) as compared to other conventional disease-modifying anti-rheumatic drugs (cDMARDs) might decrease the COVID-19-related risk of hospitalization and mortality. Methods: This large-scale case-control study nested within a cohort of cDMARD users was conducted in the Lombardy, Veneto, Tuscany and Lazio regions and Reggio Emilia (Emilia Romagna) Local Health Unit, covering a total of 25.1 million inhabitants. Claims databases were linked to loco-regional COVID-19 surveillance registries from the same catchment area through unique fully-anonymized patient identifiers. Risk of COVID-19-related outcomes was estimated as odds ratios (ORs) along with 95% confidence intervals (CIs), using a multivariate conditional logistic regression analysis, by comparing HCQ/CLQ vs methotrexate (primary comparator) and other cDMARDs (secondary comparator). In addition, the same risk for HCQ/CLQ, methotrexate and other cDMARDs separately vs nonuse of these drugs as well as for presence of rheumatic diseases vs. absence in a non-nested population was investigated. Results: From the cohort of cDMARD users, 1275 cases who were hospitalized due to COVID-19 were identified and matched to 12,734 controls. When compared to recent use of methotrexate, no statistically significant association between recent HCQ/CLQ monotherapy with COVID-19 hospitalization (OR 0.83 [95% CI, 0.69 to 1.00]) or mortality (OR 1.19 [95% CI, 0.85 to 1.67]) was observed. A statistically significant lower risk was found when comparing recent use of HCQ/CLQ to treatment with other cDMARDs and glucocorticoids concomitantly. In the sensitivity analysis in the non-nested population, HCQ/CLQ was not associated with COVID-19 hospitalization as compared with non-use, whereas a mild statistically significant increased risk for recent use of both methotrexate as monotherapy (OR 1.19 [95% CI, 1.05 to 1.34]) or other cDMARDs (OR 1.21 [95% CI, 1.08 to 1.36]) vs non-use was found. Finally, the presence of rheumatoid arthritis or systemic lupus erythematosus was not associated with COVID-19 hospitalization (OR 0.98 [95% CI, 0.89 to 1.07]) or mortality (OR 0.88 [95% CI, 0.74 to 1.05]). Conclusion: Prior exposure to HCQ/CLQ in rheumatic patients was not associated with a protective effect against COVID-19-related hospitalization and mortality. On the contrary, an increased risk in patients receiving other cDMARDs was observed when compared to non-use, especially in those patients concomitantly treated with glucocorticoids. This is likely attributable to a synergistic immunosuppressive effect, leading to increased risk of severe SARS-CoV-2 infection.
ABSTRACT
INTRODUCTION: Main clinical manifestations of SARS-CoV-2 infection are characterized by fever, dyspnea, and interstitial pneumonia, frequently evolving in acute respiratory distress syndrome (ARDS). AREAS COVERED: Features of coronavirus disease 2019 (COVID-19) presents some common points with interstitial lung disease (ILD) both idiopathic and related to rheumatoid arthritis (RA), typically characterized by a chronic progression over time and possibly complicated by acute exacerbation (AE). The study of common pathogenetic mechanisms, such as the involvement of toll-like receptor 4, could contribute to the knowledge and treatment of idiopathic and RA-ILD. Moreover, hyperinflammation, mainly characterized by increase of effector T-cells and inflammatory cytokines, and activation of coagulation cascade, observed in COVID-19 related ARDS have been already shown in patients with AE of idiopathic and RA-ILD. A literature search was performed in PubMed, Embase, Scopus, and Web of Science, together with a manual search in COVID-resource centers of the main journals. EXPERT OPINION: Despite the uncertainty about pathogenetic aspects about COVID-19- pneumonia, it could be a possible model for other forms of ILD and AE. The great amount of data from studies on COVID-19 could be helpful in proposing safe therapeutic approaches for RA-ILD, in understanding pathogenesis of usual interstitial pneumonia and to develop new therapeutic strategies for AE.
