Abstract
To define the determinants of diarrhea after bone marrow transplantation (BMT) and its nutritional sequelae, the medical records of 20 consecutive children (median age, 9 years; 13 boys and 7 girls) undergoing BMT at Children's Hospital in Birmingham, UK were surveyed. All patients who received total body irradiation (TBI) required parenteral nutrition (PN). Seventy-eight percent of TBI patients and 73% of children who received allografts developed diarrhea compared with only 27% of non-TBI patients and 22% of those who received auto grafts (P < 0.05). Ninety percent of children with diarrhea required PN. Duration of PN in these children was longer than in those without diarrhea who requested PN (P < 0.05). Despite PN, weight loss at discharge was still greater in the study group (P < 0.05). Diarrhea was associated with a significant fall in serum albumin (P < 0.005). Diarrhea and weight loss occur in children after BMT despite active PN support. Pretransplant TBI and the we of all grafts are important determinants of these complications.
