[Evaluation of adult idiopathic growth hormone deficiency with other pituitary hormones deficiency].
The type and percentage of multiple pituitary hormone deficiency (MPHD) were studied in 42 patients with idiopathic growth hormone deficiency (IGHD). It was found that the development of secondary sexual characteristics was poor or absent in 39 patients (93%) with gonadotropin deficiency (GnD). Mean serum testosterone (T), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in the 39 patients were significantly less than those of normal adult males (P less than 0.01). Mean testicular volume in 36 patients with GnD was significantly less than that in 3 with normal T level. We also found that 24-hour urinary free cortisol level (24 hour UFC) was low in 24 (57.1%) of 42 patients, but it is important that none had obvious symptoms of hypoadrenocorticism such as hypoglycemia, hypotension etc and received adrenal-corticosteroid treatment. 22 (52.4%) of the 42 patients suffered from hypothyroidism, with serum thyroxine (T4) level lower than normal but thyrotrophin (TSH) within normal range. 6 patients with hypothyroidism had moderate symptoms such as cold intolerance, constipation, rough and dry skin, slowing down both mentally and physically. 17 patients have treated with thyroxine. From the results mentioned above, 14 of the 41 patients with MPHD had pan-pituitary hormones (LH, FSH, TSH, ACTH) deficiency, only one had isolated growth hormone deficiency. Among all the patients, 23 underwent breech delivery and 11 patients had birth asphyxia. We therefore conclude that: (1) most of the IGHD cases are complicated with other pituitary hormone deficiency; (2) most of the IGHD cases have with MPHD; (3) Breech delivery and birth asphyxia were important etiological factors of IGHD.
