Kids diagnosed with multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19 infection recover fully within 6 months after infection, according to research presented in JAMA Pediatrics. Data came from more than 1,200 pediatric patients treated at 32 North American pediatric hospitals from March 2020 to January 2022. MIS-C is concerning because kids with the diagnosis are at risk for cardiovascular complications, meanwhile, the authors found that myocardial involvement occurred in 60.5% of patients studied. Although sick enough to need hospitalization, 86.3% of kids recovered by 2 weeks post-hospitalization in terms of energy, sleep, appetite, cognition, and mood. More than 95% improved at 6 months.
Also good news: The researchers found that by 6 months after discharge, 99% of the pediatric patients with MIS-C had normalization of left ventricular systolic function, and 92.3% had normalization of coronary artery dimensions.
