Abstract
Objective of the study — to investigate the disorders of growth hormone (GH) secretion in women with polycystic ovary syndrome (PCOS) compared to patients with non-functional pituitary adenomas (NFPA). Under our supervision during period from September 2015 to March 2016, there were 15 female outpatients of childbearing age with PCOS and 15 — with NFPA. Average age of patients was 25.5 and 28.9 years, respectively. The duration of disease ranged from 7 months to 9 years. It was found that in both groups, there were neuroendocrine disorders typical for each pathology. So, in the first group of patients with PCOS, the following violations were most often: obesity, striae, acanthosis, аcne, hyperandrogenemia, hyperpolymenorrhea, and in the second one — secondary amenorrhea, hyperprolactinemia, panhypopituitarism. In both groups, there was anovulation, as well as decline of GH and insulin-like growth factor‑1 (IGF‑1) secretion. In addition, patients with NFPA had significantly decreased basal levels of tropic hormones — GH, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) on the background of hyperprolactinemia and normal values of IGF‑1, while in patients with PCOS, the levels of GH, LH, FSH were reduced on the background of hyperandrogenemia and IGF‑1 decline. Thus, it was found that in the group of patients with PCOS, there was the most significant reduction of basal IGF‑1 levels, whereas GH deficiency was less frequent. Patients with NFPA had panhypopituitarism, namely combined deficiency of GH, LH, FSH, thyroid stimulating hormone, while IGF‑1 deficiency was less frequent. Disorders of GH and IGF‑1 secretion identified in our study confirm the literature data that patients with PCOS have a reduction in the levels of GH and IGF‑1 on the background of hyperinsulinemia and hyperandrogenaemia.
