Pediatric multi-system inflammatory syndrome temporally associated with COVID-19 (PIMS-TS) is a serious complication of previous SARS-CoV-2 infection. This retrospective study identified laboratory risk factors that affect the severity and resistance to standard therapy of PIMS-TS. The study found that certain laboratory parameters can be used as predictors of disease severity.
Pediatric multi-system inflammatory syndrome temporally associated with COVID-19 (PIMS-TS) is a serious complication of a previous SARS-CoV-2 infection. The disease causes multiple organ failure, but in some patients, a more severe course of the disease is observed. The treatment is multidirectional and depends on the severity and course of the disease, as some patients do not respond to the recommended treatment. The aim of this study was to identify laboratory risk factors affecting the more severe course of the disease and resistance to standard therapy. It is a single-center retrospective study considering 51 patients with PIMS-TS. Clinical features, laboratory results, and additional imaging tests data were taken into account. Fifty-one patients with PIMS-TS were hospitalized within a 16-month observation period. In the studied group, 26/51 children (51%) were girls. The mean age of patients was 7 years. Sex of the patient was not a risk factor for changes in cardiovascular system or severe course of the disease. Sixteen patients (31.3%) required transfer to the intensive care unit. Children with initially higher concentrations of NT-proBNP, troponin, creatinine, triglycerides, C-reactive protein, procalcitonin, ferritin, D-dimers and lower hematocrit, platelet count, lymphocytes, and ejection fraction should be strictly observed as they have a higher risk of severe course of the disease. Conclusions: Laboratory parameters especially markers of myocardial damage, markers of inflammation, blood count, as wells as biochemical parameters are significant risk indicators of severe course of PIMS -TS and their concentration can be defined as predictor of disease severity.
