[COVID-19: treatment strategies of German-speaking pediatric rheumatologists : Results of an online survey].

BACKGROUND

Reliable data on the course and treatment of pediatric COVID-19 ("corona virus disease 2019") in immunosuppressed patients with rheumatic diseases are missing.

AIM

Delineation of individual strategies of the members of the Society for Pediatric Rheumatology (GKJR) in cases of COVID-19.

METHODS

In May 2020 all GKJR members were invited to take part in an online survey. Opinion data regarding an approach using disease-modifying anti-rheumatic drugs (DMARD) in cases of COVID-19 as well as the readiness to use new therapeutic agents in patients in different stages of the disease were collected.

RESULTS

A total of 71 respondents (27.3% of all contacted pediatric rheumatologists) took part in the survey. Of these 28.2% had treated patients with COVID-19. Over 95% of the respondents did not support a preventive adaptation of the anti-rheumatic treatment during the SARS-CoV‑2 pandemic. In the case of outpatients under immunosuppression with proven COVID-19 more than 50% of the respondents would refrain from administering intravenous high-dose steroids, cyclophosphamide, anti-CD20 antibodies as well as BAFF, CTLA‑4 and TNF-alpha blockades. Conversely, >70% of the respondents would continue the treatment with nonsteroidal anti-inflammatory drugs, hydroxychloroquine (HCQ), oral steroids, mycophenolate, IL‑1 blockade and immunoglobulins (Ig). In the case of inpatients 74.6% of respondents would consider targeted COVID-19 treatment. In stable patients with oxygen treatment (stage I) HCQ (18.3%), azithromycin (16.9%) and Ig (9.9%) were most frequently used. In cases of early signs (stage II) or a manifest cytokine storm (stage III) anakinra (40.8% for stage II and 46.5% for stage III), tocilizumab (26.8% and 40.8%, respectively), steroids (25.4% and 33.8%, respectively) and remdesivir (29.6% and 38.0%, respectively) were most frequently used. The need for a personalized approach based on the current clinical situation was emphasized by many respondents.

CONCLUSION

The currently low prevalence of COVID-19 in Germany limits the general clinical experience. Therefore, the presented results have to be interpreted with caution and mostly as hypothetical treatment considerations. It is to be expected that there will always be a limited amount of evidence on pediatric COVID-19; therefore, a continuous and critical exchange of expert opinions on the treatment strategies is important.
