CLINICAL MANIFESTATIONS OF SARS-CoV2 INFECTIONS IN CHILDREN AND ADOLESCENTS WITH RHEUMATIC AND MUSCULUSKELETAL DISEASES - SURVEY DATA FROM GERMANY
ANNALS OF THE RHEUMATIC DISEASES(2021)
摘要
Background:Although children and adolescents are less likely to develop COVID-19 and generally show milder disease courses, it is unclear what impact the SARS-CoV2 infection has on children and adolescents with rheumatic and musculoskeletal disease (RMD). Due to their underlying disease as well as therapeutic immunosuppression these patients may be at higher risk of being more severely affected by SARS-CoV2. Furthermore, SARS-CoV2 infection might trigger a flare of the underlying disease.Objectives:To evaluate clinical characteristics and disease course of COVID-19 in children and adolescents with RMD and to analyze possible effects of SARS-CoV2 infection on the underlying disease under different therapeutic regimens.Methods:Data from juvenile patients with RMD recorded via the SARS-CoV2 questionnaire within the National Pediatric Rheumatology Database and the registry for hospitalized children and adolescents with COVID-19 of the German Society for Pediatric Infectious Diseases were analyzed. In addition to age, sex and diagnosis, information was collected about the date and method of a positive SARS-CoV2 testing, reason for testing, on clinical manifestations, disease course, treatment and outcome of COVID-19, on drug therapy at the time of virus detection, on disease activity (NRS 0 – 10, 0 = best) of the underlying disease at the last visit before and after the SARS-CoV2 infection.Results:From April 17th 2020 until January 25th 2021, data of 67 patients with RMD and confirmed SARS-CoV2 infection were collected. Mean age was 13.5 ± 3.9 years with equal sex distribution. The majority of patients were diagnosed with juvenile idiopathic arthritis (JIA, 64%), 12 (18%) patients had an autoinflammatory disease (FMF, CAPS, PFAPA, TRAPS) and 5 (7%) a connective tissue disease. Fifty-two patients (78%) were treated with a disease modifying antirheumatic drug (DMARD), 39% with a biological DMARD and 9% systemic glucocorticoids at the time of SARS-CoV-2 infection. Nineteen patients (28%) were tested for SARS-CoV-2 because of typical symptoms, the majority (67%) because of contact to an infected person. PCR was used most often (in 60 %).52 patients (78%) developed symptoms of COVID-19, 15 patients remained asymptomatic. The most common symptom of COVID-19 was rhinitis (42%) and fever (38%), followed by fatigue (34%), taste/smell disorder (33%), sore throat (27%) and cough (23%).Disease severity was graded as mild in 44 of 52 (85%) symptomatic patients, only two patients were hospitalized, one of whom required intensive care and died of cardiorespiratory failure 3 days after symptom onset. In 22 of 26 (85%) SARS-CoV2-positive patients, no relevant increase in disease activity (difference in NRS ≤ 1 before/after infection) of the underlying disease was observed 31 days after symptom onset (median, IQR 17-52 days). One patient, who had paused tocilizumab for 2 doses, experienced a flare of his seronegative polyarthritis 2 months after asymptomatic SARS-CoV-2 infection.Conclusion:In our cohort, the clinical picture of COVID-19 in children and adolescents with RMD was similar to that of healthy peers. The majority of patients showed mild disease course with good outcome under various medications, however, one patient with a severe course of COVID-19 died. In addition, SARS-CoV2 infection does not appear to have a relevant impact on the underlying disease activity, whereas discontinuation of therapy might pose a risk of flare.Disclosure of Interests:None declared.
