BACKGROUND Women living with HIV (WLWH) have higher rates of prolonged secondary amenorrhea (no flow for ≥1 year) than HIV-negative women. Both having amenorrhea and being HIV positive are associated with lower areal bone mineral density (BMD). However, their combined BMD effects remain unclear. Therefore, we investigated prolonged amenorrhea and BMD in WLWH and controls. METHODS This cross-sectional study enrolled WLWH and HIV-negative control women aged 19-68 years of similar backgrounds. We assessed BMD (Hologic; as age- and ethnicity-matched Z-scores) in the Children and women: AntiRetrovirals and Markers of Aging cohort. Participants were stratified by amenorrhea history defined as past/present lack of menses for ≥1 year at age 45 and younger and not because of surgery, breastfeeding, pregnancy, or hormonal contraception. Hip and spine Z-scores by amenorrhea/no amenorrhea used linear models with multivariable analysis for relationships within WLWH. RESULTS WLWH (N = 129) were similar to controls (N = 129) in age, body mass index, ethnicity, and substance use. Among WLWH, 21% experienced prolonged amenorrhea vs. 9% in controls. WLWH had significantly lower total hip (mean ± SD: -0.4 ± 0.9 vs. 0.3 ± 1.1; P < 0.001) and spine (-0.5 ± 1.3 vs. 0.2 ± 1.3; P = 0.001) Z-scores than controls. Amenorrhea was independently associated with hip (P = 0.01) but not spine (P = 0.94) BMD by multivariable linear regression. WLWH with amenorrhea had lower hip Z-scores (-0.8 ± 0.9) than those without (-0.3 ± 0.8; P = 0.01). They also had higher rates of substance use, smoking, opioid therapy, hepatitis C coinfection, and lower CD4 nadir. CONCLUSIONS WLWH had higher rates of prolonged amenorrhea and lower BMD than controls. WLWH with amenorrhea experienced lower hip BMD Z-scores than those without. Prolonged amenorrhea is an added osteoporosis risk in WLWH.

To characterize comorbid disease and medication burden among women living with HIV (WLWH) in British Columbia (BC), Canada.We examined baseline data from 267 WLWH and 276 HIV-negative women, aged at least 19 years, enrolled in the Children and Women: Antiretrovirals and Markers of Aging (CARMA) cohort.Self-reported demographic, medical condition, medication, vitamin, and substance exposure data were collected at baseline CARMA study visits. We considered conditions with appropriate concomitant medications to be 'treated'. Wilcoxon rank-sum and Fisher's exact tests compared continuous and categorical variables between WLWH and HIV-negative women. Number of diagnoses, prescribed medications (excluding HIV/antiretrovirals), vitamins, and prevalence of depression/anxiety/panic disorder were compared using negative binomial and logistic regressions for continuous and binary variables, respectively.WLWH were younger [median, interquartile range (IQR) 39.9, 33.6-46.9 vs. 43.6, 31.8-54.6 years; P = 0.01], attained lower education (40.5 vs. 69.6% college/university; P 0.001), and more often currently smoked tobacco (47.9 vs. 31.9%; P 0.001) or had income less than $15 000/year (49.0 vs. 43.1%; P 0.001). Although younger, and despite omitting HIV infection, WLWH had a greater number of diagnoses (incidence rate ratio, 95% confidence interval 1.58, 1.38-1.81; P 0.001), and more depression/anxiety/panic disorder vs. controls (odds ratio, 95% CI 1.86, 1.22-2.83; P = 0.004). Our model predicts that with mean BMI (26.3), WLWH and HIV-negative peers would have two comorbid diagnoses by age 30 and 60, respectively.WLWH living in BC have more comorbid illness earlier in life than their HIV-negative peers, and have very high rates of depression/anxiety/panic disorder. Addressing mental health and comorbid conditions is essential to improving health outcomes among WLWH.

OBJECTIVE There is conflicting literature to support a link between HIV and amenorrhea. Here, we conduct a meta-analysis to summarize the results from landmark studies in this area and shed light on this important clinical association. METHODS Using a search of Ovid Medline and Embase, a total of 322 articles were screened for controlled matched observational studies of amenorrhea in premenopausal women living with HIV (WLWH). For inclusion, amenorrhea was defined as absence of menses for 3 months or longer. The meta-analysis used a random-effects model with an I2 calculated to assess heterogeneity. RESULTS Six studies from 1996 to 2010 were included in our analysis for a total of 8925 women (6570 WLWH). There was a significant association between HIV status and amenorrhea (OR 1.68, P value 0.0001) without evidence of heterogeneity (I2: 0.0%). In the majority of studies, there was no significant difference in substance use, smoking, or socioeconomic status between WLWH and controls. Additionally, in the majority of studies, amenorrhea in the setting of low BMI was significantly more frequent in WLWH than controls. CONCLUSION This meta-analysis provides a large population assessment of amenorrhea in HIV to suggest increased prevalence of menstrual disturbances in WLWH. It lends evidence suggestive that this relation is independent of substance use and socioeconomic status, but may be related to low BMI. Our findings reinforce the importance of routine assessment of reproductive health and time of last menstrual period as part of the health assessment of women, especially those living with HIV.

Objectives: To examine the long-term impact of adherence on virologic, immunologic, and dual response stratified by type of HAART regimen in treatment-naive patients starting HAART in British Columbia, Canada; and to assess the degree of virologic and immunologic response associated with emergence of drug resistance, progression to AIDS, and mortality. Methods: Eligible participants initiated HAART between 1 January 2000 and 30 November 2004, were followed until 30 November 2005, and had at least 2 years of follow-up. Virologic and immunologic responses were dichotomized at their median values. Virologic response was defined as at least 65% of follow-up time with plasma viral load (pVL) of less than 50 copies/ml. Immunologic response was defined as a CD4 cell count increase of at least 145 cells/μl. Adherence measures were based on prescription refill compliance. Proportional odds models and logistic regression were used to address our objectives. Results: The distribution of patient responses was 394 (44.9%) for CD4 + /pVL + (best), 350 (39.9%) for CD4 - /pVL + or CD4 + /pVL - (incomplete), and 134 (15.3%) for CD4-/ pVL - (worst). We found a positive correlation between adherence and virologic and immunologic responses (P
