SARS-CoV-2 infections in children and adolescents with rheumatic musculoskeletal diseases – data from the National Pediatric Rheumatology Database in Germany
Abstract
Objectives
Due to their underlying disease as well as therapeutic immunosuppression, children and adolescents with rheumatic and musculoskeletal diseases (RMD) may be at higher risk for a severe course or worse outcome of COVID-19, and SARS-CoV2 infection may trigger a flare of the RMD. To address these issues, a specific SARS-CoV-2 questionnaire was implemented in the National Pediatric Rheumatology Database (NPRD) in Germany.
Methods
Demographic, clinical and treatment data from juvenile patients with RMD as well as data about SARS-CoV-2 infection like test date and method, clinical characteristics, disease course, outcome and impact on the disease activity of the RMD documented on this questionnaire were analyzed.
Results
From April 17th, 2020, to February 14th, 2021, data were collected from 79 patients (53% female) with RMD with median age of 14 years, diagnosed with juvenile idiopathic arthritis (57%), autoinflammatory (23%) and connective tissue disease (8%). Sixty-one patients (77%) received disease-modifying antirheumatic drugs (DMARDs), 43% biologic DMARDs, and 9% systemic glucocorticoids. Sixty patients (76%) developed symptoms of COVID-19. Disease severity was mild and outcome was good in the majority of patients. Two patients were hospitalized, one of whom required intensive care and died of cardiorespiratory failure. In 84% of SARS-CoV-2-positive patients, no relevant increase in disease activity of the RMD was observed.
Conclusions
In our cohort, COVID-19 in juvenile patients with RMD under various medications was mild with good outcome in the majority of cases. SARS-CoV-2 infection does not appear to have a relevant impact on disease activity of the underlying condition.
