Objectives
Multi-system inflammatory syndrome in children (MIS-C) is a less understood and a rare complication of coronavirus disease-2019 (COVID-19). Given the scarce data regarding this novel disease, we aimed to describe the clinical features and outcomes of our patients with MIS-C and to evaluate the associated factors for the pediatric intensive care unit (PICU) admission.
Methods
The MIS-C patients under 18 years old diagnosed and treated in three referral centers between July 2020 and March 2021 were included. Data of the patients were retrospectively obtained from their medical records.
Results
Overall, 76 subjects (24 females) with a mean age of 8.17 ± 4.42 years were enrolled. Twenty-seven (35.5%) patients were admitted to the PICUs. The two most common systemic involvement patterns were cardiac and gastrointestinal. There was only one lethal outcome in a patient with underlying acute lymphoblastic leukemia. Those with higher procalcitonin levels at admission were found to stay longer in the hospital (r = 0.254, p = 0.027). The risk of PICU admission increased with age (aOR: 1.277; 95% CI: 1.089–1.498; p = 0.003) and with decreased initial serum albumin levels (aOR: 0.105; 95% CI: 0.029–0.378; p = 0.001).
Conclusion
Although there is a wide clinical variability among the patients with MIS-C, we suggest that those with older age and lower initial serum albumin levels merit close monitoring due to their higher risk for PICU admission.
Key Points • Although there is a wide variability regarding the management process among clinicians, MIS-C is a rare, severe, less understood complication of COVID-19 that may cause rapid clinical deterioration in the patients. • Clinicians should be aware of this condition in children with persistent fever and a family history of COVID-19. • Older age and low serum albumin levels are the independent predictors for the pediatric intensive care unit admission among MIS-C patients. | ||
