title: Weight loss and reduced body mass index: a critical issue in children with multiorgan chronic graft-versus-host disease.
abstract: Weight loss and malnutrition are major problems in patients with chronic graft-versus-host disease (GVHD). In adults, low body mass index (BMI) is a predictor for mortality; however, weight loss and BMI have not been studied in pediatric chronic GVHD. A retrospective study on 18 children with extensive chronic GVHD was completed. Median age at SCT was 12.3 (range 0.6-23) years; age at chronic GVHD diagnosis was 12.5 (1-23) years. Patients with multiorgan involvement had a mean maximal decrease in BMI of 20.9% and most dropped below 10th percentile in expected weight-for-age. This change in BMI not only indicates a significant decrease in weight but often a plateau in stature. In contrast, patients with one organ system involved had a mean maximal decrease in BMI of 5% and did not fall below 10th percentile. All patients with multiorgan involvement required salvage therapy beyond steroids and CSA. Three patients died due to complications of chronic GVHD. Weight loss and malnutrition (as reflected by a decrease in BMI) are clinically significant issues in children with multisystem chronic GVHD. Weight loss is likely another systemic manifestation of the disease and may contribute, along with other factors such as increased immunosuppression and infection, to increased mortality in this group.
