The role of appetite-regulating hormones: Ghrelin and leptin in the nutritional status of children with neurogenic bladder due to myelomeningocele.

We wanted to investigate serum levels of ghrelin and leptin - appetite-regulating hormones - and their correlation with the nutritional status of children with neurogenic bladder (NB) due to myelomeningocele (MMC) in comparison to healthy individuals.

This prospective analysis was conducted on 67 children with NB after MMC and 20 healthy children. Children's medical charts were analysed to determine age, gender, anthropometric measurements, body mass index (BMI), activity assessment using Hoffer's scale and renal function parameters. Serum total ghrelin and leptin levels were measured using the enzyme-linked immunosorbent assay.

There were no differences in the age, gender, weight and BMI between the studied groups. Median serum levels of ghrelin and leptin were higher compared with the reference group. A significant negative correlation between serum leptin concentration and Hoffer's scale was found in children with NB.

Elevated levels of leptin and ghrelin could be considered factors influencing nutritional status in children with NB due to MMC. Children with NB after MMC may have disturbed endocrine regulation of energy homeostasis. Physical activity may be the factor that affects serum leptin concentration.
