Épidémiologie de l'atteinte dermatologique dans le syndrome de Sjögren : données provenant de trois populations françaises de Syndrome de Sjogren primitif (TEARS, ASSESS, diapSS)

• L'atteinte cutanée est habituelle dans le syndrome de Sjögren primitif (SSp), mais la prévalence et les caractéristiques sont difficiles à établir. • L'atteinte cutanée la plus courante du SSp est la sécheresse cutanée (évaluée par l'EVA). • D'autres signes dermatologiques du SSp sont rares, mais sont associés à l'activité de l'ESSDAI dans d'autres domaines. Déterminer la prévalence et les caractéristiques de l'atteinte dermatologique dans le syndrome de Sjögren primitif (SSp). Nous avons utilisé 2 cohortes françaises de SSp (ASSESS, qui a évalué la prévalence des atteintes cutanées chez 395 patients atteints de SSp ;et diapSS, dans laquelle 76 sur 139 patients atteints de SSp ont été examinés par un dermatologue) et les données de base de l'essai randomisé TEARS (110 patients atteints de SSp récents ou actifs traités avec du rituximab ou un placebo et évalués pour la sécheresse de la peau à l'aide d'une échelle visuelle analogique (EVA) sur 100). Les manifestations cutanées incluses dans l'indice d'activité EULAR du syndrome de Sjögren (ESSDAI) étaient rares dans la cohorte ASSESS (n = 16/395, 4,1 %, principalement des purpuras ;seuls 3 avaient une activité élevée), mais elles étaient associées à une activité dans les autres domaines de l'ESSDAI (système neurologique périphérique (p < 0,001), musculaire (p < 0,01), hématologique (p < 0,05), biologique (p < 0,05), antécédents d'arthrite (p < 0,01), splénomégalie (p < 0,05) et taux de gammaglobulines plus élevés (p < 0,01)). Dans la cohorte diapSS, comparés aux patients SSp ne recevant pas de consultation dermatologique, les patients SSp qui ont eu une consultation dermatologique avaient significativement plus d'atteintes dermatologiques en dehors du score ESSDAI (38,2 % (29/76) contre 15,9 % (10/63) ;p < 0,01). L'étude TEARS a montré une forte prévalence de la sécheresse cutanée (EVA≥50 ;48, 2 %) et a constaté que les patients ayant la peau sèche présentaient des scores EVA de douleur et de sécheresse globale plus élevés (p < 0,01 et p < 0,001 respectivement). Les signes dermatologiques inclus dans le score ESSDAI sont rares. Ces atteintes cutanées sont associées à l'activité de l'ESSDAI dans divers domaines notamment à l'hypergammaglobulinémie et à l'activité globale de l'ESSDAI. L'examen dermatologique systématique est instructif pour les lésions cutanées non-spécifiques. L'atteinte cutanée la plus fréquente est la sécheresse cutanée, qui est associée à une douleur plus forte et à une sécheresse subjective globale plus importante.

Associations of baseline use of biologic or targeted synthetic DMARDs with COVID-19 severity in rheumatoid arthritis: Results from the COVID-19 Global Rheumatology Alliance physician registry.

OBJECTIVE: To investigate baseline use of biologic or targeted synthetic (b/ts) disease-modifying antirheumatic drugs (DMARDs) and COVID-19 outcomes in rheumatoid arthritis (RA). METHODS: We analysed the COVID-19 Global Rheumatology Alliance physician registry (from 24 March 2020 to 12 April 2021). We investigated b/tsDMARD use for RA at the clinical onset of COVID-19 (baseline): abatacept (ABA), rituximab (RTX), Janus kinase inhibitors (JAKi), interleukin 6 inhibitors (IL-6i) or tumour necrosis factor inhibitors (TNFi, reference group). The ordinal COVID-19 severity outcome was (1) no hospitalisation, (2) hospitalisation without oxygen, (3) hospitalisation with oxygen/ventilation or (4) death. We used ordinal logistic regression to estimate the OR (odds of being one level higher on the ordinal outcome) for each drug class compared with TNFi, adjusting for potential baseline confounders. RESULTS: Of 2869 people with RA (mean age 56.7 years, 80.8% female) on b/tsDMARD at the onset of COVID-19, there were 237 on ABA, 364 on RTX, 317 on IL-6i, 563 on JAKi and 1388 on TNFi. Overall, 613 (21%) were hospitalised and 157 (5.5%) died. RTX (OR 4.15, 95% CI 3.16 to 5.44) and JAKi (OR 2.06, 95% CI 1.60 to 2.65) were each associated with worse COVID-19 severity compared with TNFi. There were no associations between ABA or IL6i and COVID-19 severity. CONCLUSIONS: People with RA treated with RTX or JAKi had worse COVID-19 severity than those on TNFi. The strong association of RTX and JAKi use with poor COVID-19 outcomes highlights prioritisation of risk mitigation strategies for these people.

Arterial Thrombotic Events in Adult Inpatients With COVID-19.

OBJECTIVE: To evaluate the clinical course of and risk factors for arterial thrombotic events in adult inpatients with coronavirus disease 2019 (COVID-19). METHODS: All consecutive adult patients admitted for COVID-19 infection in a referral center in France and discharged from the hospital between April 1 and April 30, 2020, were included. All arterial thrombotic events that occurred through discharge were considered for analysis. Epidemiologic, demographic, clinical, laboratory, treatment, and outcome data were extracted from electronic medical records with use of a standardized data collection form. RESULTS: Overall, 531 COVID-19+ patients were analyzed. Among them, 30 (5.6%) experienced arterial thrombotic events. Arterial thrombotic events in the setting of COVID-19 infection happened at a median of 11 (5-20) days after the first symptoms of infection; occurred in high-risk patients according to traditional cardiovascular risk factors; had an atypical pattern, such as thrombosis of the aorta, upper limb, or renal arteries or cerebral microvasculopathy in 7 (23.3%) cases; and were associated with an in-hospital mortality rate of 40%. Arterial thrombotic events increased the risk of death by 3-fold in COVID-19+ patients (hazard ratio, 2.96; 95% CI, 1.4 to 4.7; P=.002). A subdistribution survival hazard model showed that a concentration of D-dimer above 1250 ng/mL increased the risk of arterial thrombotic events in COVID-19+ patients by more than 7 (subdistribution hazard ratio, 7.68; 95% CI, 2.9 to 20.6; P<.001). CONCLUSION: A dramatically high rate of in-hospital death was observed in patients who suffered arterial thrombotic events in the setting of COVID-19 infection. A D-dimer level above 1250 ng/mL at entry may identify COVID-19+ patients at risk for arterial thrombotic events.

Glucocorticoids with low-dose anti-IL1 anakinra rescue in severe non-ICU COVID-19 infection: A cohort study.

BACKGROUND: The optimal treatment for patients with severe coronavirus-19 disease (COVID-19) and hyper-inflammation remains debated. MATERIAL AND METHODS: A cohort study was designed to evaluate whether a therapeutic algorithm using steroids with or without interleukin-1 antagonist (anakinra) could prevent death/invasive ventilation. Patients with a ≥5-day evolution since symptoms onset, with hyper-inflammation (CRP≥50mg/L), requiring 3-5 L/min oxygen, received methylprednisolone alone. Patients needing ≥6 L/min received methylprednisolone + subcutaneous anakinra daily either frontline or in case clinical deterioration upon corticosteroids alone. Death rate and death or intensive care unit (ICU) invasive ventilation rate at Day 15, with Odds Ratio (OR) and 95% CIs, were determined according to logistic regression and propensity scores. A Bayesian analysis estimated the treatment effects. RESULTS: Of 108 consecutive patients, 70 patients received glucocorticoids alone. The control group comprised 63 patients receiving standard of care. In the corticosteroid±stanakinra group (n = 108), death rate was 20.4%, versus 30.2% in the controls, indicating a 30% relative decrease in death risk and a number of 10 patients to treat to avoid a death (p = 0.15). Using propensity scores a per-protocol analysis showed an OR for COVID-19-related death of 0.9 (95%CI [0.80-1.01], p = 0.067). On Bayesian analysis, the posterior probability of any mortality benefit with corticosteroids+/-anakinra was 87.5%, with a 7.8% probability of treatment-related harm. Pre-existing diabetes exacerbation occurred in 29 of 108 patients (26.9%). CONCLUSION: In COVID-19 non-ICU inpatients at the cytokine release phase, corticosteroids with or without anakinra were associated with a 30% decrease of death risk on Day 15.

Managing patients with rheumatic diseases during the COVID-19 pandemic: The French Society of Rheumatology answers to most frequently asked questions up to May 2020.

BACKGROUND: Rheumatologists must contend with COVID-19 pandemic in the management of their patients and many questions have been raised on the use of both anti-inflammatory drugs and disease-modifying anti-rheumatic drugs (DMARD). The French Society of Rheumatology (SFR) selected the most critical ones to the daily practice of a rheumatologist and a group of 10 experts from SFR and Club Rheumatism and Inflammation (CRI) boards proposed responses based on the current knowledge of May 2020. METHODS: Following the availability of the first 18 questions and statements, 1400 individuals consulted the frequently asked questions between the March 31, 2020 and April 12, 2020. As a result, 16 additional questions were forwarded to the SFR, and answered by the board. An additional round of review by email and video conference was organized, which included updates of the previous statements. The scientific relevance of 5 of the questions led to their inclusion in this document. Each response received a final assessment on a scale of 0-10 with 0 meaning no agreement whatsoever and 10 being in complete agreement. The mean values of these votes for each question are presented as the levels of agreement (LoA) at the end of each response. This document was last updated on April 17, 2020. RESULTS: Based on current scientific literature already published, in most circumstances, there is no contraindication to the initiation or continuation of anti-inflammatory drugs as well as DMARDs. If signs suggestive of infection (coronavirus or other) occur, treatments should be discontinued and resumed, if necessary, after 2 weeks without any symptoms. Only, some signals suggest that people taking an immunosuppressive dose of corticosteroid therapy are at greater risk of developing severe COVID-19. Intra-articular injections of glucocorticoids are allowed when there is no reasonable therapeutic alternative, and providing that precautions to protect the patient and the practitioner from viral contamination are adopted, included appropriate information to the patient. CONCLUSIONS: Currently available data on managing patients with rheumatic diseases during the COVID-19 pandemic are reassuring and support continuing or initiating symptomatic as well as specific treatments of these diseases, the main target of their management remaining their appropriate control, even during this pandemic.
