Insights

Multisystem Inflammatory Syndrome in Children (MIS-C) can alter body composition, leading to increased fat mass and decreased fat-free mass for up to six months post-infection. This highlights potential long-term impacts on pediatric health.

Area of Science:

  • Pediatric Endocrinology
  • Infectious Diseases
  • Body Composition Analysis

Background:

  • Acute coronavirus disease 2019 (COVID-19) negatively impacts body composition in adults and children.
  • Multisystem Inflammatory Syndrome in Children (MIS-C) is a serious complication of COVID-19 requiring thorough investigation of its long-term effects.

Purpose of the Study:

  • To longitudinally evaluate changes in body composition among children diagnosed with MIS-C.
  • To compare body composition changes in MIS-C patients with a control group.

Main Methods:

  • A cohort study involving 40 pediatric patients (aged 2-18) with MIS-C.
  • Repeated physical examinations and anthropometric measurements (weight, height, BMI z-score, circumferences, skinfolds) during hospitalization and follow-up (10, 30, 90, 180 days post-discharge).
  • Calculation of fat mass and fat-free mass using predictive equations; comparison with a pediatric nutritional outpatient clinic control group.

Main Results:

  • Significant decrease in BMI z-score, arm circumference z-score, arm muscular area z-score, and arm fat area z-score during hospitalization.
  • Fat Mass Index (FMI) significantly increased over time, peaking at 30 days post-discharge.
  • Fat-free mass index decreased during hospitalization.

Conclusions:

  • This is the first study to assess pediatric MIS-C body composition longitudinally up to six months.
  • Increased FMI and fat deposit parameters were observed six months after the acute event.
  • Sedentary lifestyles post-MIS-C may contribute to adipose tissue accumulation in children.
