Follicle-stimulating hormone in postmenopausal women living with HIV: a prevalence study

Objectives We examined follicle-stimulating hormone (FSH) levels in women living with HIV aged > 45 reporting >= 12 months' amenorrhoea, and investigated correlation with menopausal symptoms. Methods A cross-sectional substudy of 85 women from the Positive Transitions through the Menopause (PRIME) Study who reported irregular periods at entry into the PRIME Study and >= 12 months' amenorrhoea at recruitment into this substudy. Serum FSH was supplemented with clinical data and menopausal symptom assessment. Serum FSH > 30 mIU/mL was defined as consistent with postmenopausal status. Associations between FSH and menopausal symptom severity were assessed using Pearson's correlation and the Kruskal-Wallis test. Results Median age was 53 years [interquartile range (IQR): 51-55]; all were on antiretroviral therapy, three-quarters (n = 65) had a CD4 T-cell count > 500 cells/mu L and 91.8% (n = 78) had an HIV viral load (VL) < 50 copies/mL. Median FSH was 65.9 mIU/mL (IQR: 49.1-78.6). Only four women (4.7%) had FSH <= 30 mIU/mL; none reported smoking or drug use, all had CD4 T-cell count >= 200 cells/mu L, and one had viral load (VL) >= 50 copies/mL. Median body mass index (BMI) was elevated compared with women with FSH > 30 mIU/mL (40.8 vs. 30.5 kg/m(2)). Over a quarter (28.2%) reported severe menopausal symptoms, with no correlation between FSH and severity of menopausal symptoms (p = 0.21), or hot flushes (p = 0.37). Conclusions Four women in this small substudy had low FSH despite being amenorrhoeic; all had BMI >= 35 kg/m(2). We found that 95% of women with HIV aged > 45 years reporting >= 12 months' amenorrhoea had elevated FSH, suggesting that menopausal status can be ascertained from menstrual history alone in this group.
