Acute respiratory viral adverse events during use of antirheumatic disease therapies: A scoping review.

Introduction: COVID-19 is an acute respiratory viral infection that threatens people worldwide, including people with rheumatic disease, although it remains unclear to what extent various antirheumatic disease therapies increase susceptibility to complications of viral respiratory infections.

Objective: The present study undertakes a scoping review of available evidence regarding the frequency and severity of acute respiratory viral adverse events related to antirheumatic disease therapies.

Methods: Online databases were used to identify, since database inception, studies reporting primary data on acute respiratory viral infections in patients utilizing antirheumatic disease therapies.

Antiphospholipid antibodies and the risk of thrombocytopenia in patients with systemic lupus erythematosus: A systematic review and meta-analysis.

Background: According to criteria for the classification of Systemic Lupus Erythematosus (SLE), thrombocytopenia is one of the disease-defining hematologic disorders. Since the recognition of Antiphospholipid Syndrome (APS), thrombocytopenia was frequently reported but several studies yielded contradictory results on the association between aPL-positivity and thrombocytopenia.

Methods: We evaluated the role of antiphospholipid antibodies (aPL) and different aPL profiles on the risk of thrombocytopenia in SLE patients by conducting a systematic review and meta-analysis of available literature from 1987 to 2018.
