RESUMEN
OBJECTIVE: To describe the clinical efficacy of tixagevimab/cilgavimab in pre-exposure prophylaxis in patients at risk of severe COVID-19 and unresponsive to vaccination (anti-SARS-CoV-2 antibodies <260 BAU/mL) in rheumatology. METHODS: In this multicenter observational study we included patients with autoimmune or inflammatory diseases who received a pre-exposure prophylaxis by tixagevimab/cilgavimab between December 2021 and August 2022. The endpoint was incidence and severity of COVID-19. RESULTS: Tixagevimab/cilgavimab was administered to 115 patients, median age 62 years (52-71), with chronic arthritis (n = 53), connective tissue disease (n = 38) or vasculitis (n = 11). Main background immunosuppressants were rituximab (n = 98), corticosteroids (n = 62, median dose 5mg, CI95% 5-8 mg) and methotrexate (n = 48). During a median follow-up of 128 days (93-173), COVID-19 occurred in 23/115patients (20%), Omicron identified for the 8 genotyped patients. During study period, the average weekly incidence was 1071/100.000 inhabitants in Ile-de-France vs. 588/100.000 in our patients. Patients who received a 2-injections regimen had a lower risk of infection than with a single injection (16/49, 33% vs. 5/64, 8%, p = 0.0012). The COVID-19+ patients did not differ from uninfected patients concerning age, comorbidities, underlying rheumatic disease, immunosuppressant. All COVID-19 were non-severe. The tolerance of injections was excellent. CONCLUSION: In a population with autoimmune or inflammatory diseases at risk of severe COVID-19 unresponsive to vaccination, pre-exposure prophylaxis by tixagevimab/cilgavimab was associated with lower incidence of COVID-19 and no severe infection to report.
RESUMEN
The management of digital ulcers in systemic sclerosis is difficult. While the 2017 European League Against Rheumatism (EULAR) guidelines clearly defined the use of systemic therapies for digital ulcers, little is known about the efficacy of locoregional treatments. The aim of this review is to systematically assess the spectrum of published locoregional therapies for digital ulcers. A total of 58 studies were included. Among the different locoregional treatment strategies described, injections of fat-derived cells and botulinum toxin showed promising results in the reduction of pain and the number of digital ulcers. By contrast, this review found that sympathectomy yielded disappointing results, with low rates of effectiveness and frequent recurrence. For other treatments, such as hyperbaric oxygen therapy, phototherapy (ultraviolet A), low-level light therapy, intermittent compression, Waon therapy, extracorporeal shockwave, vitamin E gel, and topical dimethyl sulphoxide, the conflicting results or limited published data reflected the low level of evidence. Larger randomized clinical trials are required to confirm the validity of promising techniques.

OBJECTIVES: Tropheryma whipplei infection can manifest as inflammatory joint symptoms, which can lead to misdiagnosis of inflammatory rheumatic disease and the use of disease-modifying antirheumatic drugs. We investigated the impact of diagnosis and treatment of Tropheryma whipplei infection in patients with inflammatory rheumatic disease. METHODS: We initiated a registry including patients with disease-modifying antirheumatic drugs-treated inflammatory rheumatic disease who were subsequently diagnosed with Tropheryma whipplei infection. We collected clinical, biological, treatment data of the inflammatory rheumatic disease, of Tropheryma whipplei infection, and impact of antibiotics on the evolution of inflammatory rheumatic disease. RESULTS: Among 73 inflammatory rheumatic disease patients, disease-modifying antirheumatic drugs initiation triggered extra-articular manifestations in 27% and resulted in stabilisation (51%), worsening (34%), or improvement (15%) of inflammatory rheumatic disease. At the diagnosis of Tropheryma whipplei infection, all patients had rheumatological symptoms (mean age 58 years, median inflammatory rheumatic disease duration 79 months), 84% had extra-rheumatological manifestations, 93% had elevated C-reactive protein, and 86% had hypoalbuminemia. Treatment of Tropheryma whipplei infection consisted mainly of doxycycline plus hydroxychloroquine, leading to remission of Tropheryma whipplei infection in 79% of cases. Antibiotic treatment of Tropheryma whipplei infection was associated with remission of inflammatory rheumatic disease in 93% of cases and enabled disease-modifying antirheumatic drugs and glucocorticoid discontinuation in most cases. CONCLUSIONS: Tropheryma whipplei infection should be considered in inflammatory rheumatic disease patients with extra-articular manifestations, elevated C-reactive protein, and/or hypoalbuminemia before disease-modifying antirheumatic drugs initiation or in inflammatory rheumatic disease patients with an inadequate response to one or more disease-modifying antirheumatic drugs. Positive results of screening and diagnostic tests for Tropheryma whipplei infection involve antibiotic treatment, which is associated with complete recovery of Tropheryma whipplei infection and rapid remission of inflammatory rheumatic disease, allowing disease-modifying antirheumatic drugs and glucocorticoid discontinuation.
