Serious infection risk of tofacitinib compared to biologics in patients with rheumatoid arthritis treated in routine clinical care.

Recently, serious infections related to the use of tofacitinib (TOF) for treatment of rheumatoid arthritis (RA) have raised considerable interest. This study aimed to compare the risk for serious infections in patients with RA upon receiving TOF versus biologic disease-modifying antirheumatic drugs (bDMARDs) by age at treatment initiation. We identified adult RA patients exposed to TOF or bDMARDs using data collected by the Swiss registry for inflammatory rheumatic diseases (SCQM) from 2015 to 2018.

Angioinvasive aspergillosis mimicking giant cell arteritis in an 81-year-old man with jaw pain and vision loss.

The present case report focuses on an immunocompromised 81-year-old patient initially diagnosed with Waldenström's disease. The patient experienced a gradual vision loss and jaw pain with high erythrocyte sedimentation rate. We first suspected giant cell arteritis, despite inconclusive assessment, including a negative temporal artery biopsy.

[Cases of eosinophilia in patients treated with Tocilizumab for rheumatoid arthritis].

Hypereosinophilia is a haematological complication that can lead to severe organ damage. This article describes 2 patients who presented eosinophilia under treatment with tocilizumab for rheumatoid arthritis. We will describe the evolution of eosinophilia over time, with the monitoring of medication and discuss the potential link with the treatment as well as the importance of this manifestation in the context of the disease.

Does tenosynovitis of the hand detected by B-mode ultrasound predict loss of clinical remission in rheumatoid arthritis? Results from a real-life cohort.

Objective: The role of US-detected tenosynovitis (USTS) in the management of rheumatoid arthritis remains controversial. The aim of this study was to investigate whether tenosynovitis can predict a flare in rheumatoid arthritis patients in remission in a real-life cohort.

Methods: Rheumatoid arthritis patients from the Swiss Clinical Quality Management cohort were included in this study if they were in clinical remission, defined by 28-joint disease activity score (DAS28-ESR) <2.

Incidence of COVID-19 in patients treated with infliximab compared with patients treated with rituximab.

Objective: To determine whether patients with inflammatory autoimmune diseases treated with rituximab (RTX) have more severe forms of COVID-19 compared with patients treated with anticytokine therapies, such as Tumour Necrosis Factor (TNF) inhibitors.

Methods: We included all patients who were on either RTX or infliximab (IFX) in two Swiss cantons during the first wave of the COVID-19 pandemic. We collected self-reported symptoms compatible with COVID-19, PCR-confirmed diagnoses of COVID-19 and the evolution of COVID-19 infections.
