Pattern of Common Hormonal Disorders among Patients with Polycystic Ovarian Syndrome at a Tertiary Health Facility in Nigeria

Abstract

Background: Polycystic ovarian syndrome (PCOS) is a disease associated with multiple reproductive and metabolic endocrine disorders. It is associated with cardiometabolic complications with established morbidity and mortality.

Aim: We studied the pattern of these endocrine disorders associated with PCOS will aid the understanding of the pathophysiology of this relatively incompletely understood syndrome, particularly among Africans.

Patients, Materials and Methods: One hundred adult females aged between 18 and 44 years, who were newly diagnosed with PCOS, and 100 age‑matched non‑PCOS women were involved in the study. Their serum samples were analyzed for follicle‑stimulating hormone (FSH), luteinizing hormone (LH), prolactin, progesterone, estradiol, testosterone, leptin, and anti‑Mullerian hormone (AMH) using ELISA method.

Results: The mean age of the test subjects in this study was 26.4 ± 6.0 years versus 33.3 ± 6.6 years in controls. The mean weights and body mass index of the test subjects and controls were 89.1 ± 13.9 kg versus 64.7 ± 11.3 kg, P = 0.04, and 34.01 ± 3.5 kg/m² versus 23.8 ± 3.9 kg/m² , P = 0.034, respectively. The mean serum LH was significantly higher among subjects than that of controls (11.4 ± 7.4 vs. 5.7 ± 4.8 mIU/mL, P = 0.001); similarly the mean serum LH: FSH ratio was significantly higher among subjects and controls in this study (1.9 ± 1.1 vs. 1.1 ± 0.8, P = 0.042). Serum AMH, insulin, leptin, and testosterone levels were higher among subjects than controls (7.5 ± 5.4 vs. 2.7 ± 0.4 ng/mL, P = 0.001, 21.6 ± 7.3 vs. 18.0 ± 3.01 µIU/mL, P = 0.004, and 18.6 ± 4.0 vs. 3.5 ± 1.5 ng/mL, P = 0.003, 1.0 ± 0.2 vs. 0.6 ± 0.2 ng/mL, P = 0.042, respectively). Mean serum prolactin was significantly higher among subjects when compared to controls. The prevalence of hyperinsulinemia, hyperleptinemia, and hyperandrogenemia among subjects in this study was higher when compared to controls.

Conclusion: PCOS is a disease of multiple and inter‑related endocrine disorders; a study of the frequencies and distributions of these associated disorders can aid the understanding of the pathophysiology of the disease particularly among Africans where limited studies have been carried out.
