Non-islet-cell tumor associated with hypoglycemia in a child: successful long-term therapy with growth hormone.
Hypoglycemia occurred in a 2-year-old girl with neuroblastoma. Initially, growth hormone secretion was suppressed, and she had low levels of insulin-like growth factor (IGF)-I and IGF binding protein-3, but elevated levels of large molecular weight IGF-II. We postulated that the pathogenesis of her hypoglycemia involved production of IGF-II by her neuroblastoma, leading to GH suppression and an abnormally elevated ratio of IGF to IGF binding protein. She was successfully treated with growth hormone; treatment was associated with normalization of the growth hormone-dependent growth factor levels and with euglycemia.
