OBJECTIVE: To evaluate the secretion of growth hormone in patients with fibromyalgia (FM).
METHODS: Serum concentrations of growth hormone (24 h profiles), insulin-like growth factor I (IGF), and IGF binding protein-3 were determined in 10 women with FM and in 10 healthy controls. Quality of sleep was assessed by means of a visual analog scale.
RESULTS: Sleep was significantly more disturbed in the patients than in controls. A significantly lower secretion of growth hormone was found in the patients in comparison with healthy controls.
CONCLUSION: These results suggest that growth hormone secretion is decreased in patients with FM. Substitution therapy with low doses of growth hormone may be worth evaluating in the treatment of FM.
