Mesenchymal tumours are a well recognised cause of spontaneous hypoglycaemia. The mechanism is thought to relate to hypersecretion by tumour cells of high molecular mass insulin-like growth factor-II (pro-IGF-II), with consequent suppression of growth hormone (GH) secretion. The use of recombinant human (rh)GH has been reported to alleviate hypoglycaemia in non-islet cell tumour hypoglycaemia, and the mechanism is thought to relate to GH-mediated increments in serum levels of IGF-binding protein-3 (IGFBP-3), thereby reducing the bioavailability of IGF-II. We report the effect of increasing doses of rhGH on the clinical condition and serum IGF-I and IGFBP-3 levels in two patients with solitary pleural fibrous tumours causing severe hypoglycaemia. Hypoglycaemia was successfully alleviated in each patient although, despite using large doses of rhGH, the observed increments in IGFBP-3 were only modest. We postulate that the beneficial effects of rhGH in this situation are likely to be multifactorial and not simply related to increments in serum IGFBP-3 levels.
