RESUMO

OBJECTIVES: We sought to better understand factors associated with ovarian aging in women with HIV (WWH). DESIGN: HIV has been associated with diminished fertility, younger age at menopause, and shorter leukocyte telomere length (LTL), a marker of cellular aging. We herein examine cross-sectional and longitudinal associations between LTL, anti-Müllerian hormone (AMH), and HIV. METHODS: We included WWH and HIV-negative women 12-50 years of age in the CARMA cohort with one or more study visit(s). LTL and AMH were measured by qPCR and ELISA, respectively. Women were analyzed in peak reproductive (<35 years) vs. late reproductive (≥35 years) life phases. Using multivariable mixed-effect linear or logistic regressions, we assessed factors associated with AMH and ΔAMH/year while adjusting for relevant confounders. RESULTS: WWH had shorter LTL and lower AMH levels compared to HIV-negative controls despite being of similar age. After adjusting for relevant factors, HIV was associated with 20% lower AMH levels in women under 35 years of age and shorter LTL was associated with AMH levels below 2 ng/ml among women aged 35 years or older. Longitudinally, ΔAMH/year was largely related to initial AMH level among older women, and to age in younger women. CONCLUSIONS: Factors associated with AMH change across women's reproductive lifespan. Lower AMH among peak reproductive aged WWH suggests that HIV may have an initial detrimental effect on ovarian reserve, an observation that may warrant counseling around pregnancy planning. In women aged 35 years or older, the association between shorter LTL and lower AMH suggests that the immune and reproductive aging connections are more important in this age group.

RESUMO

IMPORTANCE: With improved HIV care, more women living with HIV (WLWH) are aging and entering menopause. Understanding any increased risk conferred by a potentially earlier menopause transition is important for the care of these women. OBJECTIVE: There is conflicting literature regarding the association between HIV and an earlier onset of menopause. We conducted a systematic review to summarize the literature on the association between HIV and age at menopause. EVIDENCE REVIEW: A search of Ovid MEDLINE, EMBASE, and Web of Science identified 894 articles. We included cohort studies that assessed age at menopause, primary ovarian insufficiency (POI), or early menopause among WLWH and used the World Health Organization definition of menopause as ≥12 months of amenorrhea. FINDINGS: Nine studies were included and eight reported on age at menopause. Across studies, the age at menopause for WLWH fell between 46 and 50 years. Five of seven studies reported that WLWH had an earlier menopausal transition than HIV negative controls/the general population. Six studies reported on the prevalence of POI or early menopause among WLWH, with all studies demonstrating an increased prevalence of both among WLWH. CONCLUSIONS: Our systematic review summarizes the literature around HIV and age at menopause. Many studies reported a high prevalence of POI and early menopause among WLWH; a factor that may partially account for the observed lower age at menopause. As only one study included biochemical confirmation of menopause, it remains unclear whether individuals with early menopause or POI were truly menopausal or had prolonged amenorrhea due to other causes. Overall, our findings highlight the need for further investigation with studies that include an HIV negative control group and biochemical confirmation of menopause to better understand whether menopause truly is occurring earlier among WLWH.

RESUMO

OBJECTIVE: To evaluate the birth rates of women living with HIV (WLWH) compared to the general population in British Columbia (BC), Canada. METHODS: We retrospectively reviewed clinical and population level surveillance data from 1997 to 2015. Live birth rates from 1997 to 2015 among WLWH aged 15-49 years were compared with those of all BC women. Next, the number of live births among WLWH with a live birth between 1997-2012 and HIV-negative controls matched 1:3 by geocode were compared. RESULTS: WLWH had a lower birth rate compared to all BC women [31.4 (95%CI, 28.6-34.3) vs. 40.0 (39.3-40.1)/1000 person years]. Stratified by age, WLWH aged 15-24 years had a higher birth rate while WLWH aged 25-49 years had a lower birth rate than BC women (p<0.01). Between 1997 and 2015, birth rates for both populations decreased among women aged 15-24 years, and increased among women aged 25-49 years, most strikingly among WLWH 35-49 years (p<0.01). When comparing WLWH with a live birth to HIV-negative geocode matched controls, WLWH aged 15-24 years (p = 0.03) and aged 25-34 years (p<0.01) had more live births than controls while WLWH aged 35-49 years did not (p = 0.06). CONCLUSIONS: On a population level, WLWH have lower birth rates than the general population. However, this is not observed among WLWH who have ever given birth compared with matched controls, suggesting that sociodemographic factors may play an important role. WLWH are increasingly giving birth in their later reproductive years. Taken together, our data supports the integration of reproductive health and HIV care.
