The prevention of mother to child transmission of HIV has resulted in reduced burden of pediatric HIV-infection, but the prevalence of maternal HIV infection remains high in sub-Saharan African countries. HIV-exposed-uninfected infants have an increased risk of morbidity and mortality due to infectious diseases than HIV-unexposed infants, particularly during the first six months of life, which in part might be due to lower levels of pathogen-specific protective antibodies acquired transplacentally from their mothers. This could be mitigated by vaccinating pregnant women to boost antibody levels; although vaccine responses among HIV-infected pregnant women might differ compared to HIV-uninfected women. We reviewed studies that compared natural and vaccine-induced antibody levels to different epitopes between HIV-infected and HIV-uninfected pregnant women. Most studies reported lower baseline/pre-vaccination antibody levels in HIV-infected pregnant women, which may not be reversed by antiretroviral therapy during pregnancy. There were only few studies on vaccination of HIV-infected pregnant women, mainly on influenza virus and group B Streptococcus (GBS) vaccines. Immunogenicity studies on influenza vaccines indicated that HIV-infected pregnant women had lower vaccine induced hemagglutination inhibition antibody titers and a decreased likelihood of seroconversion compared to HIV-uninfected women; and while higher CD4+ T-lymphocyte levels were associated with better immune responses to vaccination, HIV viral load was not associated with responses. Furthermore, infants born to influenza vaccinated HIV-infected pregnant women also had lower antibody levels and a lower proportion of HIV-exposed infants had titers above the putative correlate of protection compared to HIV-unexposed infants. The immunogenicity of a CRM 197 -conjugated trivalent GBS vaccine was also lower in HIV-infected pregnant women compared to HIV-uninfected women, irrespective of CD4+ T

Broadly neutralizing antibodies (bNAbs) targeting conserved epitopes on the HIV envelope glycoprotein have been identified in blood from HIV-1 infected women. We investigated whether antibodies in the genital tract from these women share similar epitope specificities and functional profiles as those in blood. Immunoglobulin (Ig)G and IgA antibodies were isolated from cervicovaginal lavages or Softcups from 13 HIV-infected women in the CAPRISA cohort using Protein G and Peptide M, respectively. Binding antibodies to envelope antigens were quantified by ELISA and binding antibody multiplex assay. Neutralizing antibody titers and epitope targets were measured using the TZM-bl assay with Env-pseudotyped wild-type and mutated viruses. HIV-specific IgG, but not IgA, was detected in genital secretions and the ratio of total IgG to HIV-specific IgG was similar to plasma. HIV-specific IgG reacted with multiple envelope antigens, including V1V2, gp120, gp140 and gp41. Two women had high plasma titers of HIV-specific IgG3 which was also detected in their genital tract samples. IgG from the genital tract had neutralizing activity against both Tier 1 and Tier 2 primary HIV-isolates. Antibodies targeting well known glycan epitopes and the membrane proximal region of gp41 were detected in genital secretions, and matched specificities in plasma. Women with plasma bNAbs have overlapping specificities in their genital secretions, indicating that these predominantly IgG isotype antibodies may transudate from blood to the genital tract. These data provide evidence that induction of systemic HIV-specific bNAbs can lead to antiviral immunity at the portal of entry.

To determine the rate and predictors of community-acquired bacterial pneumonia and its effect on human immunodeficiency virus (HIV) disease progression in HIV-infected women, we performed a multiple-site, prospective study of HIV-infected women in 4 cities in the United States. During the period of 1993-2000, we observed 885 HIV-infected and 425 HIV-uninfected women with a history of injection drug use or high-risk sexual behavior. Participants underwent semiannual interviews, and CD4+ lymphocyte count and viral load were assessed in HIV-infected subjects. Data regarding episodes of bacterial pneumonia were ascertained from medical record reviews. The rate of bacterial pneumonia among 885 HIV-infected women was 8.5 cases per 100 person-years, compared with 0.7 cases per 100 person-years in 425 HIV-uninfected women (P < .001). In analyses limited to follow-up after 1 January 1996, highly active antiretroviral therapy (HAART) and trimethoprim-sulfamethoxazole (TMP-SMX) use were associated with a decreased risk of bacterial pneumonia. Among women who had used TMP-SMX for 12 months, each month of HAART decreased bacterial pneumonia risk by 8% (adjusted hazard ratio [HR(adj)], 0.92; 95% confidence interval [CI], 0.89-0.95). Increments of 50 CD4+ cells/mm3 decreased the risk (HR(adj), 0.88; 95% CI, 0.84-0.93), and smoking doubled the risk (HR(adj), 2.12; 95% CI, 1.26-3.55). Bacterial pneumonia increased mortality risk (HR(adj), 5.02; 95% CI, 2.12-11.87), with adjustment for CD4+ lymphocyte count and duration of HAART and TMP-SMX use. High rates of bacterial pneumonia persist among HIV-infected women. Although HAART and TMP-SMX treatment decreased the risk, bacterial pneumonia was associated with an accelerated progression to death. Interventions that improve HAART utilization and promote smoking cessation among HIV-infected women are warranted.

Low-dose hydrocortisone (LDH) enhances aspects of learning and memory in select populations including patients with PTSD and HIV-infected men. HIV-infected women show impairments in learning and memory, but the cognitive effects of LDH in HIV-infected women are unknown. Double-blind, placebo-controlled, cross-over study examining the time-dependent effects of a single low-dose administration of hydrocortisone (10 mg oral) on cognition in 36 HIV-infected women. Participants were first randomized to LDH or placebo and then received the opposite treatment one month later. Cognitive performance was assessed 30 minutes and 4 hours after pill administration to assess, respectively nongenomic and genomic effects. Self-reported stress/anxiety and salivary cortisol were assessed throughout sessions. LDH significantly increased salivary cortisol levels versus placebo; levels returned to baseline 4-hours post-administration. At the 30-minute assessment, LDH enhanced verbal learning and delayed memory, working memory, behavioral inhibition, and visuospatial abilities. At the 4-hour assessment, LDH enhanced verbal learning and delayed memory compared to placebo. LDH-induced cognitive benefits related to reductions in cytokines and to a lesser extent to increases in cortisol. The extended benefits from 30 minutes to 4 hours of a single administration of LDH on learning and delayed memory suggest that targeting the HPA axis may have potential clinical utility in HIV-infected women. These findings contrast with our findings in HIV-infected men who showed improved learning only at the 30-minute assessment. Larger, longer-term studies are underway to verify possible cognitive enhancing effects of LDH and the clinical significance of these effects in HIV.

There is limited information on full viral suppression and low-level HIV-RNA viremia in HIV-infected women at the end of pregnancy. We investigated HIV-RNA levels close to delivery in women on antiretroviral treatment in order to define rates of complete suppression, low-level viremia, and quantifiable HIV-RNA, exploring as potential determinants some clinical and viroimmunological variables. Plasma samples from a national study in Italy, collected between 2003 and 2012, were used. According to plasma HIV-RNA levels, three groups were defined: full suppression (target not detected), low-level viremia (target detected but <37 copies/ml), and quantifiable HIV-RNA (≥37 copies/ml). Multivariable logistic regression was used to define determinants of full viral suppression and of quantifiable HIV-RNA. Among 107 women evaluated at a median gestational age of 35 weeks, 90 (84.1%) had HIV-RNA <37 copies/ml. Most of them (59/90, 65.6%) had full suppression, with the remaining (31/90, 34.4%) showing low-level viremia (median: 11.9 copies/ml; IQR 7.4-16.3). Among the 17 women with quantifiable viral load, median HIV-RNA was 109 copies/ml (IQR 46-251), with only one case showing resistance (mutation M184V; rate: 9.1%). In multivariable analyses, women with higher baseline HIV-RNA levels and with hepatitis C virus (HCV) coinfection were significantly more likely to have quantifiable HIV-RNA in late pregnancy. Full viral suppression was significantly more likely with nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimens and significantly less likely with higher HIV-RNA in early pregnancy. No cases of HIV transmission occurred. In conclusion, HIV-infected pregnant women showed a high rate of viral suppression and a low resistance rate before delivery. In most cases no target HIV-RNA was detected in plasma, suggesting a low risk of subsequent virological rebound and development of resistance. Women with high levels of HIV-RNA in early pregnancy and those who have

To understand how regional body composition affects bone mineral density (BMD) in HIV-infected and HIV-uninfected women. Dual energy x-ray absorptiometry was used to measure regional lean and fat mass and BMD at lumbar spine (LS), total hip (TH), and femoral neck (FN) in 318 HIV-infected and 122 HIV-uninfected Women's Interagency HIV Study participants at baseline and 2 and 5 years later. Total lean and fat mass were measured using bioimpedance analysis. Multivariate marginal linear regression models assessed the association of HIV status and body composition on BMD change. Compared with HIV-uninfected women, HIV-infected women were older (44 vs. 37 years), more likely to be Hepatitis C virus-infected (32% vs. 14%), and postmenopausal (26% vs. 3%) and had lower baseline total fat mass, trunk fat, and leg fat. In multivariate models, increased total lean mass was independently associated with increased BMD at LS, TH, and FN, and total fat mass was associated with increased BMD at TH and FN (all P < 0.05). When total fat was replaced in multivariate models with trunk fat and leg fat, increased trunk fat (and not leg fat) was associated with increased TH and FN BMD (P < 0.001). Total fat and lean mass are strong independent predictors of TH and FN BMD, and lean mass was associated with greater LS BMD. Regardless of HIV status, greater trunk fat (and not leg fat) was associated with increased TH and FN BMD, suggesting that weight-bearing fat may be a more important predictor of BMD in the hip.

We examined the effects of physical attractiveness on the assumed mode of HIV acquisition. 176 students read a description of an HIV-positive target whose photograph was placed above the description. A 2 (target gender) by 2 (attractive or unattractive target) factorial design was used. Unattractive targets were perceived as more likely to have acquired HIV through homosexual relationships. Further, men were perceived as more likely than women to have acquired HIV homosexually. Attractiveness did not bias health-care allocations regarding the infected target.

Violence and human immunodeficiency virus (HIV) are two critical public health problems affecting the lives of millions of women today. The purpose of this article is to review the state of science that exists in linking the phenomena of violence and HIV infection in women. The history and scope of violence and HIV infection is presented. Theoretical models for the phenomena of violence and abuse against women and HIV risk behavior reduction are explored. The literature review consists of 44 research articles that examine risk factors for violence and HIV, violence associated with HIV/AIDS disclosure, history of violence and HIV/AIDS, forced or coercive sex and HIV/AIDS, and violence associated with HIV self-protection conduct. Implications for nursing practice and nursing research are presented.

Chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection is frequent in HIV-infected persons but their impact on pregnant HIV-infected women is understudied. We explored whether these coinfections are associated with adverse pregnancy outcomes and lower response to antiretroviral therapy (ART). Pregnancies in HIV-1-infected women included in the ANRS French Perinatal Cohort between 2005 and 2013 were analyzed if HBV and HCV infection statuses were available. Among 4236 women, the prevalence of HBV (HBs Ag+) and HCV (RNA+) were 6.2% (95% confidence interval: 5.4 to 6.8) and 1.7% (1.3 to 2.1), respectively. HCV coinfection was strongly associated with a history of drug use; HBV coinfection was 6 times more frequent in women born in Sub-Saharan Africa than in European France. Baseline HIV viral load, CD4 count, and HIV care during pregnancy were similar in coinfected and monoinfected HIV mothers, except that 90% of HBV/HIV women were receiving tenofovir and/or lamivudine or emtricitabine. HCV coinfection was significantly associated with cholestasis [adjusted odds ratio: 4.1 (1.5-10.8), P = 0.005], preterm delivery [3.0 (1.6-5.7), P < 0.001], lower CD4 [2.6 (1.0-6.4), P < 0.001], and detectable viral load [2.3 (1.0-5.5), P = 0.06] at the end of pregnancy. HBV coinfection was not associated with any of these outcomes. In HIV-infected women, chronic HBV infection, mostly treated using targeted ART, had no major impact on the course of pregnancy. By contrast, chronic HCV infection was associated with a higher risk of obstetrical complications and a poorer immune-virological response to ART. It is yet unknown whether cure of HCV infection before conception can limit these adverse outcomes.

Preexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others. In this randomized, double-blind, placebo-controlled trial, we assigned 2120 HIV-negative women in Kenya, South Africa, and Tanzania to receive either a combination of tenofovir disoproxil fumarate and emtricitabine (TDF-FTC) or placebo once daily. The primary objective was to assess the effectiveness of TDF-FTC in preventing HIV acquisition and to evaluate safety. HIV infections occurred in 33 women in the TDF-FTC group (incidence rate, 4.7 per 100 person-years) and in 35 in the placebo group (incidence rate, 5.0 per 100 person-years), for an estimated hazard ratio in the TDF-FTC group of 0.94 (95% confidence interval, 0.59 to 1.52; P=0.81). The proportions of women with nausea, vomiting, or elevated alanine aminotransferase levels were significantly higher in the TDF-FTC group (P=0.04, P<0.001, and P=0.03, respectively). Rates of drug discontinuation because of hepatic or renal abnormalities were higher in the TDF-FTC group (4.7%) than in the placebo group (3.0%, P=0.051). Less than 40% of the HIV-uninfected women in the TDF-FTC group had evidence of recent pill use at visits that were matched to the HIV-infection window for women with seroconversion. The study was stopped early, on April 18, 2011, because of lack of efficacy. Prophylaxis with TDF-FTC did not significantly reduce the rate of HIV infection and was associated with increased rates of side effects, as compared with placebo. Despite substantial counseling efforts, drug adherence appeared to be low. (Supported by the U.S. Agency for International Development and others; FEM-PrEP ClinicalTrials.gov number, NCT00625404.).

Rates of sexually transmitted infections (STI) and HIV are highest in the southern U.S., but vary widely by gender, age and risk behavior. Current guidelines recommend annual screening for chlamydia, gonorrhea, syphilis and trichomoniasis in all sexually active women with HIV. Screening rates and test positivity for chlamydia, gonorrhea, syphilis and trichomoniasis were determined per calendar year in this retrospective cohort study of women in care at an urban HIV clinic in Birmingham, Alabama, 2013-2015. Chlamydia, gonorrhea, and trichomonas infection were detected by molecular diagnostics and syphilis by serology. A combined endpoint for CT/GC/syphilis (STI-3) was created based on similar test positivity and predictors. Predictors of STI-3 were identified using logistic regression and generalized estimating equations. Among 745 women with HIV, median age was 46.8 years, 78.8% were Black and 61% were sexually active. In 2015, 83.7% of women were tested for STI. Test positivity was 1.0% for chlamydia, 0.5% for gonorrhea, 1.6% for syphilis, and 13.3% for trichomoniasis. Independent predictors of STI-3 were recent chlamydia or gonorrhea (OR 3.7, 95% CI 1-13.4, p=0.047), public insurance compared to private (OR 3.5, CI 1-11.8, p=0.048) and sex after drugs/alcohol (OR 3.0, CI 1.2-8.0, p=0.025). Women age ≥50 were less likely to have STI (OR 0.3, CI 0.1-1, p=0.040). In a cohort of women engaged in HIV care in the southern United States, detection of chlamydia, gonorrhea and syphilis was infrequent but trichomoniasis was common. Many women screened for STI were low-risk and universal testing strategies warrant evaluation.

Tenofovir disoproxil fumarate (TDF) has been associated with kidney tubular dysfunction and reduced renal function. Limited studies were performed in Europe and Asia that related plasma tenofovir (TFV) concentration with renal function; no such studies to date have been performed on Africans. To investigate the correlation between plasma tenofovir (TFV) concentration and certain renal function markers in HIV-infected women on TDF antiretroviral therapy (ART). These markers were also compared to a HIV-uninfected control group. HIV-infected women ( n = 30) on TDF-based ART were matched with 30 controls for age and body mass index. Renal markers analysed were estimated glomerular filtration rate (eGFR), creatinine clearance (CrCl), serum creatinine, albuminuria, glucosuria, serum urea, serum uric acid, urine sodium and maximum tubular reabsorption of phosphate. Baseline eGFR and CrCl data were obtained retrospectively for the HIV-infected women. Plasma TFV was assayed using a validated HPLC-MS/MS method. Stepwise regression, Mann-Whitney test, unpaired and paired t -tests were applied in the statistical analyses. TFV concentration was independently associated with albuminuria (adjusted r 2 = 0.339 ; p = 0.001) in HIV-infected women. In the adjusted (weight) analysis, eGFR ( p = 0.038), CrCl ( p = 0.032) and albuminuria ( p = 0.048) were significantly higher in HIV-infected compared to the uninfected women, but eGFR was abnormally high in HIV-infected women. Both eGFR ( p < 0.001) and CrCl ( p = 0.008) increased from baseline to follow-up in HIV-infected women. Plasma TFV concentration was associated with increased albuminuria in HIV-infected women in this sub-study. Both eGFR and CrCl were increased in HIV-infected women from baseline. These findings should be confirmed in larger studies, and hyperfiltration in HIV-infected women warrants further investigation.

Background and Objectives: There is conflicting data on the effect of HIV infection as well as antiretroviral therapy (ART) on pregnancy outcome. The objectives of this study were to compare pregnancy outcomes in women with and without HIV infection, and to evaluate the effect of HAART on pregnancy in HIV-infected women. Methods: This is a prospective case record analysis of 212 HIV-infected women delivering between 2002 and 2015, in a tertiary health care center in India. The pregnancy outcome in HIV-infected women was compared to 238 HIV-uninfected controls. Women received ART for prevention of mother to child transmission as per protocol which varied during the period of study. Effect of use of ART on preterm birth (PTB) and intrauterine growth restriction (IUGR) was analyzed. Results: HIV-infected women were more likely to have PTB, IUGR, and anemia (9.4%, 9.9%, 5.2%) compared to uninfected women (7.6%, 5%, 3.8%), this did not reach statistical significance (P-value = >0.05). The incidence of PIH, diabetes mellitus and intrahepatic cholestasis of pregnancy was similar in both groups. Mean birth weight was significantly lower in neonates of HIV-infected women (2593.60±499g) than HIV-uninfected women (2919±459g) [P-value=0.001]. neonatal intensive care unit admissions were also significantly higher in infants born to HIV-infected women (P-value=0.002). HIV-infected women on ART had decreased incidence of PTB and IUGR. Conclusion and Global Health Implications: Good antenatal care and multidisciplinary team approach can optimize pregnancy outcomes in HIV-infected women. PMID:28798896

Tanzania is the country hit the hardest by the HIV epidemic in Sub-Saharan Africa. The present study was carried out to examine the factors of HIV infection among women who lived in an urban area in Tanzania. The Tanzania HIV/AIDS and Malaria Indicator Survey (2011-12) data was used. The sample size for urban and rural women who had been tested for HIV and ever had sex was 2227 and 6210 respectively. Bivariate and multivariate logistic regression analyses were used. The present study found that rural women were significantly less likely to be HIV-infected compared to urban women (OR = 0.612, p<0.00). About 10% urban women were HIV-infected whereas 5.8% women in rural areas were HIV positive. Women who had more than five sex partners were significantly four times more likely to be HIV-infected as compared to women who had one sex partner (OR = 4.49, p<0.00). The results of this study suggest that less-educated women, women belonging to poor or poorer quintile, women spending nights outside and women having more than one sex partner were significantly more likely to have HIV infection among urban women as compared to rural women. There is an urgent need for a short and effective program to control the HIV epidemic in urban areas of Tanzania especially for less-educated urban women.

Although the incidence of HIV among women on probation, parole and alternatives to incarceration programs is significant to public health, drivers of this concentrated epidemic among women under community corrections remain understudied. This study examined prevalence of HIV and sexually transmitted infections and the associations between substance use, socio-demographic factors and the prevalence of biologically-confirmed HIV and other sexually transmitted infections among a sample of 337 substance-using women recruited from community correction sites in New York City. Prevalence of HIV was 13% and sexually transmitted infections was 26% ( Chlamydia, trachomatis and Neisseria gonorrhea). After adjusting for covariates, HIV-positive women were 1.42 times more likely to use crack/cocaine than HIV-negative women (95% CI = 1.05-1.92). HIV-positive women were 25% less likely than HIV-negative women to report any unprotected vaginal and anal sex with their main partner (95% CI = 0.57-0.99). They were 70% less likely than HIV-negative women to report unprotected vaginal sex with a non-paying casual partner (95% CI = 0.1-0.9) and 22% less likely to report unprotected vaginal sex across all partners (95% CI = 0.61-0.99). Community corrections settings may be optimal venues to launch HIV/sexually transmitted infections prevention that have potential to reach and engage an ever-growing number of substance-using women.

This study examined HIV and malaria co-infection as a risk factor for urinary tract infections (UTIs) in pregnancy. The study group included 74 pregnant women, 20 to 42 years of age, who attended the antenatal clinic at the Specialist Hospital at Akure, Ondo State, Nigeria. Forty-four of the pregnant women were either HIV seropositive with malaria infection (HIV+Mal+) or HIV seropositive without malaria (HIV+Mal-). The remaining thirty pregnant women served as controls and included women HIV seronegative but with malaria (HIV-Mal+) and women HIV seronegative without malaria. UTI was indicated by a bacterial colony count of greater than 10⁵/mL of urine, using cysteine lactose electrolyte deficient medium (CLED) as the primary isolation medium. Bacterial isolates were characterized using convectional bacteriological methods, and antibiotics sensitivity tests were carried out using the disk diffusion method. A total of 246 bacterial isolates were recovered from the cultures, with a mean of 3.53 isolates per subject. Women who were HIV+Mal+ had the most diverse group of bacterial isolates and the highest frequency of UTIs. The bacterial isolates from the HIV+Mal+ women also showed the highest degree of antibiotic resistance. While pregnancy and HIV infection may each represent a risk factor for UTI, HIV and malaria co-infection may increase its frequency in pregnancy. The higher frequency of multiple antibiotic resistance observed among the isolates, particularly isolates from HIV+Mal+ subjects, poses a serious public health concern as these strains may aggravate the prognosis of both UTI and HIV infection.

Control of genital infections remains challenging in most regions. Despite advocacy by the World Health Organization for syndromic case management, there are limited data on the syndromic approach, especially in HIV care settings. This study compared the syndromic approach with laboratory diagnosis among women in HIV care in Kenya. A mobile team visited 39 large HIV care programmes in Kenya and enrolled participants using population-proportionate sampling. Participants provided behavioural and clinical data with genital and blood specimens for lab testing. Among 1063 women, 68.4% had been on antiretroviral therapy >1 year; 58.9% were using cotrimoxazole prophylaxis; 51 % had CD4+T-lymphocytes < 350 cells/µL. Most women (63.1%) reported at least one genital symptom. Clinical signs were found in 63% of women; and 30.8% had an aetiological diagnosis. Bacterial vaginosis (17.4%), vaginal candidiasis (10.6%) and trichomoniasis (10.5%) were the most common diagnoses. Using laboratory diagnoses as gold standard, sensitivity and positive predictive value of the syndromic diagnosis for vaginal discharge were 47.6% and 52.7%, respectively, indicating a substantial amount of overtreatment. A systematic physical examination increased by 9.3% the positive predictive value for genital ulcer disease. Women attending HIV care programmes in Kenya have high rates of vaginal infections. Syndromic diagnosis was a poor predictor of those infections. © The Author(s) 2015.

To determine if human immunodeficiency virus (HIV) infection or antiretroviral therapy interferes with maternal levels of free human β-chorionic gonadotrophin (hCGβ) and pregnancy-associated plasma protein-A (PAPP-A) and whether any such influence alters first-trimester Down syndrome (DS) screening in HIV-infected women. We performed a multicenter 1:2 matched case-control study comparing 84 HIV-infected women with singleton pregnancies with controls randomly selected among uninfected women, delivered and screened in the same center and matched for maternal age, geographical origin and fetal sex. Groups did not differ significantly in screening results, although case women showed a slightly lower median free hCGβ multiple of the median (MoM) (1.11 versus 1.24 MoM, p=0.32) and higher median PAPP-A MoM (1.45 versus 1.32 MoM, p=0.23) than control women. The false-positive rate was similar in the case and control groups (5% versus 6.5%, p=0.5). Biomarker levels did not differ when comparing treated and untreated patients with their respective controls, and with one another. First-trimester DS combined screening biomarker levels and calculated risk do not seem to be significantly altered by HIV infection or antiretroviral treatment. This screening strategy appears to be suitable for HIV-infected women. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

HIV prevalence is rising and has been consistently higher among women in Rwanda whereas a decreasing national HIV prevalence rate in the adult population has stabilised since 2005. Factors explaining the increased vulnerability of women to HIV infection are not currently well understood. A statistical mapping at smaller geographic units and the identification of key HIV risk factors are crucial for pragmatic and more efficient interventions. The data used in this study were extracted from the 2010 Rwanda Demographic and Health Survey data for 6952 women. A full Bayesian geo-additive logistic regression model was fitted to data in order to assess the effect of key risk factors and map district-level spatial effects on the risk of HIV infection. The results showed that women who had STIs, concurrent sexual partners in the 12 months prior to the survey, a sex debut at earlier age than 19 years, were living in a woman-headed or high-economic status household were significantly associated with a higher risk of HIV infection. There was a protective effect of high HIV knowledge and perception. Women occupied in agriculture, and those residing in rural areas were also associated with lower risk of being infected. This study provides district-level maps of the variation of HIV infection among women of child-bearing age in Rwanda. The maps highlight areas where women are at a higher risk of infection; the aspect that proximate and distal factors alone could not uncover. There are distinctive geographic patterns, although statistically insignificant, of the risk of HIV infection suggesting potential effectiveness of district specific interventions. The results also suggest that changes in sexual behaviour can yield significant results in controlling HIV infection in Rwanda.

The parasite Schistosoma haematobium frequently causes genital lesions in women and could increase the risk of human immunodeficiency virus (HIV) transmission. This study quantifies the HIV target cells in schistosome-infected female genital mucosa. Cervicovaginal biopsies with and without schistosomiasis were immunostained for quantification of CD4+ T lymphocytes (CD3, CD8), macrophages (CD68), and dendritic Langerhans cells (S100 protein). We found significantly higher densities of genital mucosal CD4+ T lymphocytes and macrophages surrounding schistosome ova compared with cervicovaginal mucosa without ova (P = 0.034 and P = 0.018, respectively). We found no increased density of Langerhans cells (P = 0.25). This study indicates that S. haematobium may significantly increase the density of HIV target cells (CD4+ T lymphocytes and macrophages) in the female genitals, creating a beneficial setting for HIV transmission. Further studies are needed to confirm these findings and to evaluate the effect of anti-schistosomal treatment on female genital schistosomiasis. PMID:22144444

Background There is evidence of an interaction between human immunodeficiency virus (HIV) and human papillomavirus (HPV) resulting in increased HPV-associated morbidity and cancer mortality among HIV-positive women. This study aims to determine how the natural history of cervical HPV infection differs by HIV status. Methods A total of 1,320 women (47% were positive for HIV-1 and/or HIV-2) were followed for an average of two years in Senegal, West Africa between 1994 and 2010. Cytology (with a sub-sample of histology) and HPV DNA testing were performed at approximately 4-month intervals yielding data from over 7,900 clinic visits. Competing risk modeling was used to estimate rates for transitioning between three clinically relevant natural history stages: Normal, HPV, and HSIL (high-grade squamous intraepithelial lesions). Among HIV-positive women, exploratory univariate analyses were conducted examining the impact of HPV type, infection with multiple HPV types, HIV type, CD4+ count, and age. Results HIV-positive women had higher rates of progression and lower rates of regression compared to HIV-negative women (i.e. adverse transitions). HIV-positive women had a 2.55 (95% CI: 1.69–3.86; P < 0.0001) times higher rate of progression from HPV to HSIL than HIV-negative women (with 24-month absolute risks of 0.18 and 0.07, respectively). Among HIV-positive women, HPV-16/18 infection and CD4+ count <200/mm3 were associated with adverse transitions. Conclusions Adverse HIV effects persist throughout HPV natural history stages. Impact In the limited-resource setting of sub-Saharan Africa where cervical cancer screening is not widely available, the high-risk population of HIV-positive women may be ideal for targeted screening.

This study aimed to determine changes in fertility intentions of HIV-1 infected and uninfected reproductive age women in Blantyre, Malawi. Participants were asked about their fertility intentions at baseline and at 3-month visits for 1 year. Time-to-event statistical models were used to determine factors associated with changes in fertility intentions. Overall, 842 HIV uninfected and 844 HIV infected women were enrolled. The hazard of changing from wanting no more children at baseline to wanting more children at follow-up was 61% lower among HIV infected women compared to HIV uninfected women (P < 0.01) after adjusting for other factors, while HIV infected women were approximately 3 times more likely to change to wanting no more children. The overall pregnancy rate after 12 months was 14.9 per 100 person-years and did not differ among 102 HIV uninfected and 100 infected women who became pregnant. HIV infection is a significant predictor of fertility intentions over time.

HIV is a cardiovascular disease (CVD) risk factor. However, CVD risk is often underestimated in HIV-infected women. C-reactive protein (CRP) may improve CVD prediction in this population. We examined the association of baseline plasma CRP with subclinical CVD in women with and without HIV. Retrospective cohort study. A total of 572 HIV-infected and 211 HIV-uninfected women enrolled in the Women's Interagency HIV Study underwent serial high-resolution B-mode carotid artery ultrasonography between 2004 and 2013 to assess carotid intima-media thickness (CIMT) and focal carotid artery plaques. We used multivariable linear and logistic regression models to assess the association of baseline high (≥3 mg/l) high-sensitivity (hs) CRP with baseline CIMT and focal plaques, and used multivariable linear and Poisson regression models for the associations of high hsCRP with CIMT change and focal plaque progression. We stratified our analyses by HIV status. Median (interquartile range) hsCRP was 2.2 mg/l (0.8-5.3) in HIV-infected, and 3.2 mg/l (0.9-7.7) in HIV-uninfected, women (P = 0.005). There was no statistically significant association of hsCRP with baseline CIMT [adjusted mean difference -3.5 μm (95% confidence interval:-19.0 to 12.1)] or focal plaques [adjusted odds ratio: 1.31 (0.67-2.67)], and no statistically significant association of hsCRP with CIMT change [adjusted mean difference 11.4 μm (-2.3 to 25.1)]. However, hsCRP at least 3 mg/l was positively associated with focal plaque progression in HIV-uninfected [adjusted rate ratio: 5.97 (1.46-24.43)], but not in HIV-infected [adjusted rate ratio: 0.81 (0.47-1.42)] women (P = 0.042 for interaction). In our cohort of women with similar CVD risk factors, higher baseline hsCRP is positively associated with carotid plaque progression in HIV-uninfected, but not HIV-infected, women, suggesting that subclinical CVD pathogenesis may be different HIV-infected women.

The aim of this study was to examine the association between CD4 count, human papilloma virus (HPV) infection, and the risk of cervical intraepithelial neoplasia among HIV-infected women. A cross-sectional study was conducted among 104 HIV-infected women attending an antiretroviral therapy clinic. They underwent Pap smear and cervical HPV DNA testing. The overall prevalence of HPV infection was 57.7%. HPV 16 was the commonest genotype found (38.5%); HPV 16 and 18 put together contributed to 73.3% of HPV infection; 27.5% of HIV-infected women had squamous cell abnormalities. Cervical intraepithelial neoplasia was less likely among women with CD4 count > 500/mm 3 (12%) and in those without opportunistic infections (17.8%). The prevalence of high-risk HPV infection was higher in women with high-grade squamous intraepithelial lesions or greater lesions (85.7%) as compared to women with normal cytology (52.1%). The high prevalence of HPV infection and cervical intraepithelial neoplasia in HIV-infected women warrants the need for regular Pap smear screening in these women and routine HPV vaccination for adolescents to reduce the burden of cervical cancer in India. © 2016 Japan Society of Obstetrics and Gynecology.

Despite the fact that religious affiliation is almost universal in Malawi, and religious denomination could potentially influence HIV-risk behaviors, limited data exist on its role of in HIV infection in this setting. This study was conducted to assess whether religious denominational affiliation, religiosity or place of residence were associated with sexual behaviors and HIV infection among Christian women. A total of 63 of 939 women with HIV test results (6.7%) were HIV infected. There was no association between religion or frequency of church attendance and HIV infection or condom use within the current or most recent marriage. Compared to women who lived in a village which was neither the husband's village nor her own village, women living with spouse in her own village or living in a husband's village were less likely to be HIV infected.

Introduction The Post-exposure Prophylaxis in Infants (PEPI)-Malawi trial evaluated infant antiretroviral regimens for prevention of post-natal HIV transmission. A multi-assay algorithm (MAA) that includes the BED capture immunoassay, an avidity assay, CD4 cell count, and viral load was used to identify women who were vs. were not recently infected at the time of enrollment (MAA recent, N = 73; MAA non-recent, N = 2,488); a subset of the women in the MAA non-recent group known to have been HIV infected for at least 2 years before enrollment (known non-recent, N = 54). Antibody maturation and viral diversification were examined in these women. Methods Samples collected at enrollment (N = 2,561) and 12–24 months later (N = 1,306) were available for serologic analysis using the BED and avidity assays. A subset of those samples was used for analysis of viral diversity, which was performed using a high resolution melting (HRM) diversity assay. Viral diversity analysis was performed using all available samples from women in the MAA recent group (61 enrollment samples, 38 follow-up samples) and the known non-recent group (43 enrollment samples, 22 follow-up samples). Diversity data from PEPI-Malawi were also compared to similar data from 169 adults in the United States (US) with known recent infection (N = 102) and known non-recent infection (N = 67). Results In PEPI-Malawi, results from the BED and avidity assays increased over time in the MAA recent group, but did not change significantly in the MAA non-recent group. At enrollment, HIV diversity was lower in the MAA recent group than in the known non-recent group. HRM diversity assay results from women in PEPI-Malawi were similar to those from adults in the US with known duration of HIV infection. Conclusions Antibody maturation and HIV diversification patterns in African women provide additional support for use of the MAA to identify populations with recent HIV infection. PMID:23460842

To estimate the coverage of the reporting of cases of HIV-infected pregnant women, to estimate the increase in the coverage of the reporting with the routine search of data in other Brazilian health information systems, and to identify missed opportunities for identification of HIV-infected pregnant women in Brazilian maternity hospitals. This is a descriptive study on the linkage of Brazilian databases with primary data from the "Nascer no Brasil" study and secondary database collection from national health information systems. The "Nascer no Brasil" is a national-based study carried out in 2011-2012 with 23,894 pregnant women, which identified HIV-infected pregnant women using prenatal and medical records. We searched for cases of HIV-infected pregnant women identified in the "Nascer no Brasil" study in the Information System of Notifiable Diseases, the Control System for Laboratory Tests of the National CD4+/CD8+ Lymphocyte Count and HIV Viral Load Network, and the Logistics Control System for Medications. We used the OpenRecLink software for the linkage of databases. We estimated the notification coverage, with the respective confidence interval, of the evaluated Brazilian health information systems. We estimated the coverage of the reporting of HIV-infected pregnant women in the Information System of Notifiable Diseases as 57.1% (95%CI 42.9-70.2), and we located 89.3% of the HIV-infected pregnant women (95%CI 81.2-94.2) in some of the Brazilian health information systems researched. The search in other national health information systems would result in an increase of 57.1% of the reported cases. We identified no missed opportunities for the diagnosis of HIV+ in pregnant women in the maternity hospitals evaluated by the "Nascer no Brasil" study. The routine search for information in other Brazilian health information systems, a procedure carried out by the Ministry of Health for cases of AIDS in adults and children, should be adopted for cases of HIV in

To identify social, behavioral and epidemiologic factors associated with HIV infection among HIV-infected and HIV-uninfected black women residing in North Carolina. A case-control study conducted in August 2004 in North Carolina. Cases were 18-40-year-old women with HIV infections diagnosed from 2003-2004. Controls were 18-40-yearold, HIV-negative heterosexually active women recruited from HIV testing sites. Five focus group discussions were also conducted with women not participating in the case-control study. Multivariate analyses of 31 cases and 101 controls showed that HIV-positive women were more likely to receive public assistance [adjusted odds ratio (aOR) 7.3; 95% confidence interval (CI) 2.1, 26.0], to report a history of genital herpes infection (aOR 10.6; 95% CI 2.4, 47.2), and were less likely to have discussed a variety of sexual and behavioral issues relevant to risk of HIV infection with their male partners (aOR 0.6; 95% CI 0.4, 0.8). Focus group participants indicated that financial and social demands created competing challenges for making HIV prevention a priority. Inadequate communication between black women and their sexual partners may create barriers to sexual and behavioral risk reduction. A multidimensional approach that addresses both biological factors such as herpes infection and socioeconomic factors may be needed to reduce HIV transmission in this population.

Objectives Persistence of infection with high-risk Human papillomaviruses (HR-HPV) increases the risk of incident and progressive precancerous lesions of the cervix. Rates of HR-HPV persistence have been shown to be increased among HIV-infected adult women, however there is a paucity of literature addressing HPV persistence in the young HIV-infected population. We compared rates of HR-HPV persistence between HIV-infected and HIV-uninfected young women. Methods We obtained self-collected vaginal swabs at six-month intervals from 50 HIV-uninfected and 33 HIV-infected young women recruited through a community youth center (age 17-21 years) and compared rates of HR-HPV persistence. HR-HPV testing was conducted using the Roche’s Linear Array® HPV Test. Results Eighty-three prevalent (upon baseline testing) and incident (upon subsequent testing) individual HR-HPV infections were identified among 43 members of the cohort (23 HIV-uninfected and 20 HIV-infected). At twelve months, 19% of baseline HR-HPV infections continued to be present with a statistically significant difference between HIV-uninfected and HIV-infected participants (4% versus 31%; p=0.01). Conclusions HIV-infected young women in our cohort had a seven-fold increased rate of persistence of HR-HPV overall at 12 months indicating an increased risk for incident and progressive precancerous lesions. Identification of persistent infection with HR-HPV may complement cytological findings in determining the need for colposcopy. PMID:25697074

Tuberculosis (TB) is a significant contributor to mortality in HIV-infected patients. Concurrent TB infection is also a significant contributing factor to maternal mortality in human immunodeficiency virus (HIV)-infected pregnant women. Studies addressing the outcomes of TB and HIV co-infection among pregnant women are generally infrequent. Although limited, the records maintained by the Revised National Tuberculosis Control Programme (RNTCP) and the National AIDS Control Programme (NACP) in Karnataka State, Southern India provide information about the numbers of pregnant women who are co-infected with TB and HIV and their pregnancy outcomes. We reviewed the data and conducted this study to understand how TB-HIV co-infection influences the outcomes of pregnancy in this setting. We sought to determine the incidence and treatment and delivery outcomes of TB-HIV co-infected pregnant women in programmatic settings in Karnataka State in southern India. The study participants were all the HIV-infected pregnant women who were screened for tuberculosis under the NACP from 2008 to 2012. For the purposes of this study, the program staff in the field gathered the data regarding on treatment and delivery outcomes of pregnant women. A total of seventeen pregnant women with TB-HIV co-infection were identified among 3,165,729 pregnant women (for an incidence of 5.4 per million pregnancies). The median age of these pregnant women was 24 years, and majority were primiparous women with WHO HIV stage III disease and were on a stavudine-based ART regimen. The maternal mortality rates were 18% before delivery and 24% after delivery. The abortion rate was 24%, and the neonatal mortality rate was 10%. The anti-tuberculosis treatment and anti-retroviral treatment outcome mortality rates were 30% and 53%, respectively. Although the incidence of TB among the HIV-infected pregnant women was marginally less than that among the non-HIV-infected women, the delivery outcomes were relatively

Background HIV infection closely relates to and deeply affects the reproductive career of those infected. However, little is known about the reproductive career trajectories, specifically the interaction of the timing of HIV diagnosis with the timing and sequencing of reproductive events among HIV infected women. This is the first study to describe and typify this interaction. Methods Retrospective calendar data of ever married HIV infected women aged 15-45 attending a HIV clinic in Pune, Maharashtra, Western India (N=622) on reproductive events such as marriage, cohabitation with the partner, use of contraception, pregnancy, childbirth and HIV diagnosis were analyzed using sequence analysis and multinomial logistic regression. Results Optimal matching revealed three distinct trajectories: 1) HIV diagnosis concurrent with childbearing (40.7%), 2) HIV diagnosis after childbearing (32.1%), and 3) HIV diagnosis after husband’s death (27.2%). Multinomial logistic regression (trajectory 1 = baseline) showed that women who got married before the age of 21 years and who had no or primary level education had a significantly higher risk of knowing their HIV status either after childbearing or close to their husband’s death. The risk of HIV diagnosis after husband’s death was also higher among rural women and those who were diagnosed before 2005. Conclusions Three distinct patterns of interaction of timing of HIV diagnosis with timing and sequencing of events in the reproductive career were observed that have clear implications for (i) understanding of the individual life planning process in the context of HIV, (ii) formulation of assumptions for estimating HIV infected women in need of PMTCT services, and (iii) provision of care services.

Associations of HIV with body composition were assessed, and t tests compared the groups. HIV-positive women were younger (-7.0 years, P < .001) and shorter (-2.1 cm, P < .001). Mean body weight, body mass index (BMI), total body fat, and waist-to-hip ratio (WHR) were similar. Mean fat-free mass was 2.5% greater in HIV-negative participants, and 19% of HIV-positive group had BMI <18.5 kg/m(2) versus 26% of the HIV-negative group (P < .05). CD4 counts and body composition were not associated. Malnutrition was common in this cohort of Rwandan women. However, HIV infection was not associated with nutritional status. Factors other than malnutrition may influence quality-of-life outcomes in HIV-infected Rwandan women. Initiatives to improve nutritional status should be population-wide and not restricted to the HIV-infected population.

The use of antiretroviral drugs (ARVDs) in a mother and a child can reduce the risk of vertical transmission of human immunodeficiency virus (HIV) to less than 1%; therefore, highly active antiretroviral therapy is used in all pregnant women regardless of indications for HIV-infection treatment. The major requirements for choosing an ARVD to prevent mother-to-child HIV transmission are its high safety for a pregnant woman, a fetus, and a baby and its high therapeutic efficacy. Clinical trials of darunavir (DRV) in adults and children have shown a high virologic response, good tolerance, and safety. Trials and observations have demonstrated the high efficacy and safety of a DRV when used in pregnant women. Pharmacokinetic studies in pregnant women have indicated the effective and well-tolerated concentration of a DRV when it is co-administered with low-dose ritonavir, which permits the use of a DRV for both the prevention of mother-to-child HIV transmission and the treatment of pregnant women who require antiretroviral therapy. The Russian clinical protocol "Use of ARVDs in the package of measures for the prevention of mother-to-child HIV transmission" approved by the National Scientific Society of Infectiologists in 2013 recommends DRV as an alternative drug in antiretroviral therapy regimens for pregnant women to prevent mother-to-child HIV transmission and to treat maternal HIV infection.

With the development and widespread use of combination antiretroviral therapy, HIV-infected women live longer, healthier lives. Previous research has shown that, since the adoption of combination antiretroviral therapy in the United States, rates of morbidity and adverse obstetric outcomes remained higher for HIV-infected pregnant women compared with HIV-uninfected pregnant women. Monitoring trends in the outcomes these women experience is essential, as recommendations for this special population continue to evolve with the progress of HIV treatment and prevention options. We conducted an analysis comparing rates of hospitalizations and associated outcomes among HIV-infected and HIV-uninfected pregnant women in the United States from 2004 through 2011. We used cross-sectional hospital discharge data for girls and women age 15-49 from the 2004, 2007, and 2011 Nationwide Inpatient Sample, a nationally representative sample of US hospital discharges. Demographic characteristics, morbidity outcomes, and time trends were compared using χ(2) tests and multivariate logistic regression. Analyses were weighted to produce national estimates. In 2011, there were 4751 estimated pregnancy hospitalizations and 3855 delivery hospitalizations for HIV-infected pregnant women; neither increased since 2004. Compared with those of HIV-uninfected women, pregnancy hospitalizations of HIV-infected women were more likely to be longer, be in the South and Northeast, be covered by public insurance, and incur higher charges (all P < .005). Hospitalizations among pregnant women with HIV infection had higher rates for many adverse outcomes. Compared to 2004, hospitalizations of HIV-infected pregnant women in 2011 had higher odds of gestational diabetes (adjusted odds ratio, 1.81; 95% confidence interval, 1.16-2.84), preeclampsia/hypertensive disorders of pregnancy (adjusted odds ratio, 1.58; 95% confidence interval, 1.12-2.24), viral/mycotic/parasitic infections (adjusted odds ratio, 1

We investigated leukocyte and lymphocyte subsets in HIV-infected or HIV-uninfected, pregnant or non-pregnant Malawian women to explore whether HIV infection and pregnancy may act synergistically to impair cellular immunity. We recruited 54 pregnant and 48 non-pregnant HIV-uninfected women and 24 pregnant and 20 non-pregnant HIV-infected Malawian women. We compared peripheral blood leukocyte and lymphocyte subsets between women in the four groups. Parturient HIV-infected and HIV-uninfected women had more neutrophils (each P<.0001), but fewer lymphocytes (P<.0001; P=.0014) than non-pregnant women. Both groups had fewer total T cells (P<.0001; P=.002) and CD8 + T cells (P<.0001; P=.014) than non-pregnant women. HIV-uninfected parturient women had fewer CD4 + and γδ T cells, B and NK cells (each P<.0001) than non-pregnant women. Lymphocyte subset percentages were not affected by pregnancy. Malawian women at parturition have an increased total white cell count due to neutrophilia and an HIV-unrelated pan-lymphopenia. © 2017 The Author.

OBJECTIVE To analyze women’s perceptions and coping regarding the discovery of an HIV infection. METHODS A qualitative study in an HIV/AIDS Specialist Helpdesk in Recife, PE, Northeastern Brazil, from January to September 2010, involving eight women living with asymptomatic HIV aged between 27 and 37 years, without criteria for diagnosis of AIDS infected through intercourse and monitored by the service for at least one year. Forms were used to characterize the clinical situation and semi-structured interviews to understand perceptions and feelings related to personal trajectory after diagnosis and different ways of facing the diagnosis in family and social life. Content analysis was performed as suggested by Bardin. RESULTS The thematic category that emerged was stigma and discrimination. The women had life trajectories marked by stigma, which was perceived as discrimination after the diagnosis and in the experiences of everyday life. The revelation of the infection was perceived as limiting to a normal life, leading to the need to conceal the diagnosis. The discriminatory attitudes of some health care professionals, non-specialist in HIV/AIDS, had a negative impact on future experiences in other health services. Besides the effects of institutional stigma, the perception of women was that the service did not include dedicated space for the expression of other needs beyond the disease, which could help in fighting the infection. CONCLUSIONS Living with HIV was strongly linked to stigma. The results show the importance of strengthening educational approaches and emotional support at the time of diagnosis in order to facilitate coping with the condition of seropositivity.

HIV continues to spread at high rates in sub-Saharan Africa. In particular, Swaziland is one of the countries most affected by the HIV/AIDS pandemic. Monitoring of HIV infection in Swaziland is being made by periodical investigations on HIV prevalence in pregnant women. However, knowledge of proportion of recent HIV infections is important for epidemiologic purposes to assess HIV transmission patterns. To evaluate the proportion of recent HIV infections among pregnant women and its change overtime and to analyze factors associated with recent HIV infection in Swaziland. HIV-positive sera from pregnant women were collected during the 2004 and 2006 National HIV Serosurveys conducted in Swaziland and tested for the HIV antibody avidity, in order to identify recent HIV infections. Socio-demographic and clinical information was also collected. A multivariate analysis was conducted to assess the association between recent HIV infection and socio-demographic and clinical factors. A total of 1636 serum samples were tested for HIV antibody avidity. The overall proportion of recent infections was 13.8%, with no significant difference between 2004 and 2006 (14.6% vs. 13.1%, P>0.05, respectively). At the multivariate analysis, the younger age [14-19 vs. >or=20 years; adjusted odds ratio (aOR) 2.17, 95% CI: 1.45-3.24], as well as being at first pregnancy (1 vs. >or=2; aOR 1.61, 95% CI: 1.10-2.35) was independently associated with recent HIV infection. This study shows no significant difference in the proportion of recent infections between 2004 and 2006 and suggests that young women and women at their first pregnancy are currently high-risk groups for HIV acquisition, highlighting the importance of developing targeted youth programmes to reduce the spread of HIV infection in the country.

We demonstrate the feasibility of implementing a referral and management system for cryotherapy-ineligible women in a "screen-and-treat" cervical cancer prevention program targeting HIV-infected women in Zambia. We established criteria for patient referral, developed a training program for loop electrosurgical excision procedure (LEEP) providers, and adapted LEEP to a resource-constrained setting. We successfully trained 15 nurses to perform visual inspection with acetic acid (VIA) followed by immediate cryotherapy. Women with positive tests but ineligible for cryotherapy were referred for further evaluation. We trained four Zambian physicians to evaluate referrals, perform punch biopsy, LEEP, and manage intra-operative and post-operative complications. From January 2006 through October 2007, a total of 8823 women (41.5% HIV seropositive) were evaluated by nurses in outlying prevention clinics; of these, 1477 (16.7%) were referred for physician evaluation based on established criteria. Of the 875 (59.2% of 1147 referred) that presented for evaluation, 748 (8.4% of total screened) underwent histologic evaluation in the form of punch biopsy or LEEP. Complications associated with LEEP included anesthesia reaction (n=2) which spontaneously resolved, intra-operative (n=12) and post-operative (n=2) bleeding managed by local measures, and post-operative infection (n=12) managed with antibiotics. With adaptations for a resource-constrained environment, we have demonstrated that performing LEEP is feasible and safe, with low rates of complications that can be managed locally. It is important to establish referral and management systems using LEEP-based excisional evaluation for women with cryotherapy-ineligible lesions in VIA-based "screen-and-treat" protocols nested within HIV-care programs in resource-constrained settings.

The objective of this work was to assess the prevalence of bacterial vaginosis (BV) and genital mycoplasma colonization in 251 HIV-positive compared to 200 HIV-negative women at the Maternal and Child Health (MCH) service of Saint Camille Medical Center  Ouagadougou (Burkina Faso). After revealing the cervix with a speculum, we collected swabs of vaginal discharge for the detection of pathogenic bacteria. Among HIV-positive and HIV-negative women, we identified respectively: Mycoplasma hominis (16.7% versus 5.5%); Ureaplasma urealyticum (16.3% versus 0.0%); co-infection M. hominis with U. urealyticum (13.14% versus 0.0%); Candida albicans (21.11% versus 41.5%); E. coli (9.96% versus 4.0%); and the presence of abundant vaginal discharge (27.5% versus 5.0%) respectively. The Nugent's score, utilized for the diagnosis of BV, was significantly higher in HIV-positive women (p < 0.001) associated with poor vaginal hygiene practices (p < 0.01) and no use of condoms (p < 0.01). Enterobacter, Klebsiella pneumonia, Klebsiella oxitocica, Staphylococcus epidermidis and Staphylococcus aureus, Streptococcus agalactiae, Trichomonas vaginalis, and Gardnerella vaginalis were also isolated, but in a low prevalence ranging from 0% to 5%. These results demonstrate that the HIV-positive women of Burkina Faso are frequently affected by BV and represent a reservoir for mycoplasma infection. Since these germs can lead to sterility and premature delivery, it is important to develop a policy of screening.

Objective We examined serum lipids in association with carotid artery intima-media thickness (CIMT) in HIV-infected and HIV-uninfected women. Methods In 2003–4, among 1827 Women’s Interagency HIV Study participants, we measured CIMT and lipids (high-density lipoprotein cholesterol [HDL-c], low-density lipoprotein cholesterol [LDL-c], total cholesterol [TC], non-HDL-c). A subset of 520 treated HIV-infected women had pre-1997 lipid measures. We used multivariable linear regression to examine associations between lipids and CIMT. Results In HIV-uninfected women, higher TC, LDL-c and non-HDL-c were associated with increased CIMT. Among HIV-infected women, associations of lipids with CIMT were observed in treated but not untreated women. Among the HIV-infected women treated in 2003–4, CIMT was associated both with lipids measured a decade earlier in infection, and with late lipid measurements. Conclusion Among HIV-infected women, hyperlipidemia is most strongly associated with subclinical atherosclerosis in treated women. Among treated women, the association appeared strongest early in the disease course. PMID:23089369

Background Despite a recent decline, Zimbabwe still has the fifth highest adult HIV prevalence in the world at 14.7%; 56% of the population are currently living in extreme poverty. Design Cross-sectional population-based survey of 18–22 year olds, conducted in 30 communities in south-eastern Zimbabwe in 2007. Objective To examine whether the risk of HIV infection among young rural Zimbabwean women is associated with socio-economic position and whether different socio-economic domains, including food sufficiency, might be associated with HIV risk in different ways. Methods Eligible participants completed a structured questionnaire and provided a finger-prick blood sample tested for antibodies to HIV and HSV-2. The relationship between poverty and HIV was explored for three socio-economic domains: ability to afford essential items; asset wealth; food sufficiency. Analyses were performed to examine whether these domains were associated with HIV infection or risk factors for infection among young women, and to explore which factors might mediate the relationship between poverty and HIV. Results 2593 eligible females participated in the survey and were included in the analyses. Overall HIV prevalence among these young females was 7.7% (95% CI: 6.7–8.7); HSV-2 prevalence was 11.2% (95% CI: 9.9–12.4). Lower socio-economic position was associated with lower educational attainment, earlier marriage, increased risk of depression and anxiety disorders and increased reporting of higher risk sexual behaviours such as earlier sexual debut, more and older sexual partners and transactional sex. Young women reporting insufficient food were at increased risk of HIV infection and HSV-2. Conclusions This study provides evidence from Zimbabwe that among young poor women, economic need and food insufficiency are associated with the adoption of unsafe behaviours. Targeted structural interventions that aim to tackle social and economic constraints including insufficient food should

The high incidence of multiple infections of cells by HIV sets the stage for rapid HIV evolution by means of recombination. Yet how HIV dynamics proceeds with multiple infections remains poorly understood. Here, we present a mathematical model that describes the dynamics of viral, target cell, and multiply infected cell subpopulations during HIV infection. Model calculations reproduce several experimental observations and provide key insights into the influence of multiple infections on HIV dynamics. We find that the experimentally observed scaling law, that the number of cells coinfected with two distinctly labeled viruses is proportional to the square of the total number of infected cells, can be generalized so that the number of triply infected cells is proportional to the cube of the number of infected cells, etc. Despite the expectation from Poisson statistics, we find that this scaling relationship only holds under certain conditions, which we predict. We also find that multiple infections do not influence viral dynamics when the rate of viral production from infected cells is independent of the number of times the cells are infected, a regime expected when viral production is limited by cellular rather than viral factors. This result may explain why extant models, which ignore multiple infections, successfully describe viral dynamics in HIV patients. Inhibiting CD4 down-modulation increases the average number of infections per cell. Consequently, altering CD4 down-modulation may allow for an experimental determination of whether viral or cellular factors limit viral production.

The aim of the study was to assess the rate, determinants, and outcomes of repeat pregnancies in women with HIV infection. Data from a national study of pregnant women with HIV infection were used. Main outcomes were preterm delivery, low birth weight, CD4 cell count and HIV plasma viral load. The rate of repeat pregnancy among 3007 women was 16.2%. Women with a repeat pregnancy were on average younger than those with a single pregnancy (median age 30 vs. 33 years, respectively), more recently diagnosed with HIV infection (median time since diagnosis 25 vs. 51 months, respectively), and more frequently of foreign origin [odds ratio (OR) 1.36; 95% confidence interval (CI) 1.10-1.68], diagnosed with HIV infection in the current pregnancy (OR: 1.69; 95% CI: 1.35-2.11), and at their first pregnancy (OR: 1.33; 95% CI: 1.06-1.66). In women with sequential pregnancies, compared with the first pregnancy, several outcomes showed a significant improvement in the second pregnancy, with a higher rate of antiretroviral treatment at conception (39.0 vs. 65.4%, respectively), better median maternal weight at the start of pregnancy (60 vs. 61 kg, respectively), a higher rate of end-of-pregnancy undetectable HIV RNA (60.7 vs. 71.6%, respectively), a higher median birth weight (2815 vs. 2885 g, respectively), lower rates of preterm delivery (23.0 vs. 17.7%, respectively) and of low birth weight (23.4 vs. 15.4%, respectively), and a higher median CD4 cell count (+47 cells/μL), with almost no clinical progression to Centers for Disease Control and Prevention stage C (CDC-C) HIV disease (0.3%). The second pregnancy was significantly more likely to end in voluntary termination than the first pregnancy (11.4 vs. 6.1%, respectively). Younger and foreign women were more likely to have a repeat pregnancy; in women with sequential pregnancies, the second pregnancy was characterized by a significant improvement in several outcomes, suggesting that women with HIV infection who desire multiple

We assessed mortality, treatment response, and relapse among HIV-infected and HIV-uninfected women with cervical cancer in Rio de Janeiro, Brazil. Cohort study of 87 HIV-infected and 336 HIV-uninfected women with cervical cancer. Patients at the Brazilian National Institute of Cancer (2001-2013) were matched on age, calendar year of diagnosis, clinical stage, and tumor histology. Staging and treatment with surgery, radiotherapy, and/or chemotherapy followed international guidelines. We used a Markov model to assess responses to initial therapy, and Cox models for mortality and relapse after complete response (CR). Among 234 deaths, most were from cancer (82% in HIV-infected vs. 93% in HIV-uninfected women); only 9% of HIV-infected women died from AIDS. HIV was not associated with mortality during initial follow-up but was associated more than 1-2 years after diagnosis [overall mortality: stage-adjusted hazard ratio 2.02, 95% confidence interval (CI) 1.27-3.22; cancer-specific mortality: 4.35, 1.86-10.2]. Among 222 patients treated with radiotherapy, HIV-infected had similar response rates to initial cancer therapy as HIV-uninfected women (hazard ratio 0.98, 95% CI 0.58-1.66). However, among women who were treated and had a CR, HIV was associated with elevated risk of subsequent relapse (hazard ratio 3.60, 95% CI 1.86-6.98, adjusted for clinical stage). Among women with cervical cancer, HIV infection was not associated with initial treatment response or early mortality, but relapse after attaining a CR and late mortality were increased in those with HIV. These results point to a role for an intact immune system in control of residual tumor burden among treated cervical cancer patients.

Prevalence of HIV among pregnant women in India is of great concern, especially to prevent HIV in children. Mother-to-child transmission of HIV is the most common cause of transmission of HIV in children. Prevalence of HIV infection in pregnant women in India has ranged from 0.7% to 1.2%. Thus, estimating prevalence of HIV in pregnant women would aid in developing and prioritizing prevention of parent-to-child transmission of HIV programs. All pregnant women referred to the antenatal clinic from 1993 onward were tested for HIV infection by ELISA test after pretest counseling. A woman was diagnosed to be HIV infected if she tested positive on more than two HIV ELISA tests. Prevalence of HIV infection in them was calculated and also whether there was an increasing trend was determined. A total of 123,439 pregnant women were tested for HIV from 1993 to 2004, of which 1797 women were HIV infected. Overall, the prevalence rate was found to be 1.4%. Prevalence rose from 0.76% in 1993 to 2.37% in 1998. However, from 2004, the prevalence has decreased to 0.6%. Prevalence of HIV in pregnant women in Mumbai is decreasing.

Cytomegalovirus (CMV) urinary shedding in pregnant women infected with human immunodeficiency virus (HIV) was evaluated to determine whether it poses an increased risk for congenital CMV infection (cCMV). A subset of mother-infant pairs enrolled in the perinatal NICHD HPTN 040 study (distinguished by no antiretroviral use before labor) was evaluated. Maternal and infant urines were tested by qualitative real-time polymerase chain reaction (RT-PCR) for CMV DNA with quantitative RT-PCR performed on positive specimens. Urine specimens were available for 260 women with 85.4% from the Americas and 14.6% from South Africa. Twenty-four women (9.2%) had detectable CMV viruria by qualitative PCR. Maternal CMV viruria was not associated with mean CD4 cell counts or HIV viral load but was associated with younger maternal age (P = .02). Overall, 10 of 260 infants (3.8%) had cCMV. Women with detectable peripartum CMV viruria were more likely to have infants with cCMV than those without: 20.8% (5/24) versus 2.1% (5/236), (P = .0001). Women with CMV viruria had significantly higher rates of HIV perinatal transmission (29.2% vs. 8.1%, P = .002). They were 5 times (adjusted odds ratio [aOR] = 5.6, 95% confidence interval [CI] 1.9-16.8) and nearly 30 times (aOR, 29.7; 95% CI, 5.4-164.2) more likely to transmit HIV and CMV to their infants, respectively. Maternal gonorrhea (aOR, 19.5; 95% CI, 2.5-151.3) and higher maternal HIV log10 viral load (OR, 2.8; 95% CI, 1.3-6.3) were also significant risk factors for cCMV. In this cohort of HIV-infected pregnant women not on antiretrovirals, urinary CMV shedding was a significant risk factor for CMV and HIV transmission to infants. NCT00099359. © The Author 2017.

Contraceptive preferences of HIV-infected women must be considered in efforts to integrate HIV and reproductive health services. In South Africa, contraception is often discontinued due to bleeding pattern changes. It is unknown whether HIV-infected women are more sensitive to menstrual changes and how this affects contraceptive choice. This study describes perceptions toward menses and contraceptive-induced amenorrhea among HIV-infected women. A convenience sample of 42 HIV-infected women aged 15 to 45 years was purposively recruited for three focus groups and 15 in-depth qualitative interviews which were conducted at the Perinatal HIV Research Unit, South Africa. Transcripts were coded and emergent themes grouped. One third of women reported HIV-related menstrual changes, unchanged by antiretroviral use. Menstruation was believed to purge the body of "dirty blood." Women perceived that menstruation had a negative effect on male partner sexual desire, with concern about higher HIV transmission during menstruation. Ninety-six percent of injectable contraceptive users experienced amenorrhea, regarded as troublesome and a reason for discontinuation. In Soweto, HIV diagnosis may accentuate linking menstruation with health, leading to avoidance or discontinuation of methods causing amenorrhea. Providers should intensify education on the safety of contraceptive-induced oligo/amenorrhea.

Reproductive health and family planning needs among HIV-infected women in Sub-Saharan Africa.

Review key topics and recent literature regarding reproductive health and family planning needs for HIV-infected women in Sub-Saharan Africa. Electronic searches performed in PubMed, JSTOR, and Web of Science; identified articles reviewed for inclusion. Most HIV-infected women in Sub-Saharan Africa bear children, and access to antiretroviral therapy may increase childbearing desires and/or fertility, resulting in greater need for contraception. Most contraceptive options can be safely and effectively used by HIV-infected women. Unmet need for contraception is high in this population, with 66- 92% of women reporting not wanting another child (now or ever), but only 20-43% using contraception. During pregnancy and delivery, HIV-infected women need access to prevention of mother-to-child transmission (PMTCT) services, a skilled birth attendant, and quality post-partum care to prevent HIV infection in the infant and maximize maternal health. Providers may lack resources as well as appropriate training and support to provide such services to women with HIV. Innovations in biomedical and behavioral interventions may improve reproductive healthcare for HIV-infected women, but in Sub-Saharan Africa, models of integrating HIV and PMTCT services with family planning and reproductive health services will be important to improve reproductive outcomes. HIV-infected women in Sub-Saharan Africa have myriad needs related to reproductive health, including access to high-quality family planning information and options, high-quality pregnancy care, and trained providers. Integrated services that help prevent unintended pregnancy and optimize maternal and infant health before, during and after pregnancy will both maximize limited resources as well as provide improved reproductive outcomes.

In contrast to findings from cohorts comprised primarily of HIV-infected men, verbal memory deficits are the largest cognitive deficit found in HIV-infected women from the Women's Interagency HIV Study (WIHS), and this deficit is not explained by depressive symptoms or substance abuse. HIV-infected women may be at greater risk for verbal memory deficits due to a higher prevalence of cognitive risk factors such as high psychosocial stress and lower socioeconomic status. Here, we investigate the association between perceived stress using the Perceived Stress Scale (PSS-10) and verbal memory performance using the Hopkins Verbal Learning Test (HVLT) in 1009 HIV-infected and 496 at-risk HIV-uninfected WIHS participants. Participants completed a comprehensive neuropsychological test battery which yielded seven cognitive domain scores, including a primary outcome of verbal memory. HIV infection was not associated with a higher prevalence of high perceived stress (i.e., PSS-10 score in the top tertile) but was associated with worse performance on verbal learning (p < 0.01) and memory (p < 0.001), as well as attention (p = 0.02). Regardless of HIV status, high stress was associated with poorer performance in those cognitive domains (p's < 0.05) as well as processing speed (p = 0.01) and executive function (p < 0.01). A significant HIV by stress interaction was found only for the verbal memory domain (p = 0.02); among HIV-infected women only, high stress was associated with lower performance (p's < 0.001). That association was driven by the delayed verbal memory measure in particular. These findings suggest that high levels of perceived stress contribute to the deficits in verbal memory observed in WIHS women.

Although breast-feeding is nature's way of providing nutrition to the baby, in HIV positive mothers this has been identified as one of the means through which HIV infection is transmitted from the mother to the child. In Africa where children under the age of 5 are killed by preventable diseases like diarrhoea, the issue of HIV transmission through breast feeding poses an added huge problem. Research has, however shown that exclusive infant feeding, be it breast or formula, reduces the risk substantially. It is imperative that mothers be informed about safer methods of infant feeding so that HIV infection is kept to a minimum. The objective of the study was to explore and describe the knowledge that pregnant women had about mother to child transmission of HIV infection through breast-feeding. A non-experimental quantitative exploratory and descriptive research design was used to explore the knowledge women had on mother to child transmission of HIV infection through breast-feeding. From the data collected, it showed that although women were aware of the susceptibility of children to HIV infection if fed on breast and formula feeds simultaneously by HIV positive mothers, exclusive feeding was a problem as people associated the practise with a positive HIV status. Women who had not disclosed their HIV status and were HIV positive, found it difficult to comply with the requirement to exclusively feed their infants. These either continued with complementary feeds or did not collect the free formula milk supply preferring instead to buy the formula feeds privately. In this study it was recommended that information on transmission of HIV infection from mother to child through breast -feeding including the benefits of exclusive infant feeding, be it breast or formula, for the first three to six months be provided to the community so that relatives can support the mother on infant feeding method of choice.

Background. HIV-infected women are disproportionately burdened by gynaecological complications, psychological disorders, and certain sexually transmitted infections that may not be adequately addressed by HIV-specific care. We estimate the prevalence and covariates of women's health care (WHC) utilization among harder-to-reach, treatment-experienced HIV-infected women in British Columbia (BC), Canada. Methods. We used survey data from 231 HIV-infected, treatment-experienced women enrolled in the Longitudinal Investigations into Supportive and Ancillary Health Services (LISA) study, which recruited harder-to-reach populations, including aboriginal people and individuals using injection drugs. Independent covariates of interest included sociodemographic, psychosocial, behavioural, individual health status, structural factors, and HIV clinical variables. Logistic regression was used to generate adjusted estimates of associations between use of WHC and covariates of interest. Results. Overall, 77% of women reported regularly utilizing WHC. WHC utilization varied significantly by region of residence (P value <0.01). In addition, women with lower annual income (AOR (95% CI) = 0.14 (0.04–0.54)), who used illicit drugs (AOR (95% CI) = 0.42 (0.19–0.92)) and who had lower provider trust (AOR (95% CI) = 0.97 (0.95–0.99)), were significantly less likely to report using WHC. Conclusion. A health service gap exists along geographical and social axes for harder-to-reach HIV-infected women in BC. Women-centered WHC and HIV-specific care should be streamlined and integrated to better address women's holistic health. PMID:23227316

Abstract The objective of this study was to describe attitudes, opinions, and perceived health needs of HIV-infected women in the United States. In this cross-sectional study, women were invited to participate in the Women Living Positive survey, a structured interview instrument with 45 questions. Collected data were deidentified and the margin of error was calculated as four percentage points. Incoming toll-free phone interviews were conducted from December 21, 2006, through March 14, 2007 among subjects recruited from a U.S. national network of AIDS counseling centers. Seven hundred HIV-infected women (43% African American, 28.5% Hispanic, 28.5% Caucasian; median age, 42.5 years) receiving combination antiretroviral therapy for 3 years or more replied to recruitment flyers. Overall, 55% of survey participants had never discussed gender-specific HIV treatment issues with their HIV care providers. Of the 45% who did discuss these issues, almost all (96%) were satisfied. On average, one-third of the women had seen three or more providers since beginning HIV treatment; 43% indicated they had switched providers because of communication issues. Among women who had been or were pregnant at the time of the survey (n=159), more than half (57%) had not had pre-pregnancy discussions with their HIV provider about the most appropriate HIV regimens for women attempting to become pregnant. Significant communication gaps exist between HIV-infected women and their providers when discussing gender-specific treatment issues. These data highlight a need for U.S. health care providers to incorporate discussion of gender-specific issues, including preconception and reproductive counseling, into management strategies for HIV-infected women.

To determine the lung cancer incidence and survival time among HIV-infected and uninfected women and men. Two longitudinal studies of HIV infection in the United States. Data from 2549 women in the Women's Interagency HIV Study (WIHS) and 4274 men in the Multicenter AIDS Cohort Study (MACS), all with a history of cigarette smoking, were analyzed. Lung cancer incidence rates and incidence rate ratios were calculated using Poisson regression analyses. Survival time was assessed using Kaplan-Meier and Cox proportional-hazard analyses. Thirty-seven women and 23 men developed lung cancer (46 HIV-infected and 14 HIV-uninfected) during study follow-up. In multivariable analyses, the factors that were found to be independently associated with a higher lung cancer incidence rate ratios were older age, less education, 10 or more pack-years of smoking, and a prior diagnosis of AIDS pneumonia (vs. HIV-uninfected women). In an adjusted Cox model that allowed different hazard functions for each cohort, a history of injection drug use was associated with shorter survival, and a lung cancer diagnosis after 2001 was associated with longer survival. In an adjusted Cox model restricted to HIV-infected participants, nadir CD4 lymphocyte cell count less than 200 was associated with shorter survival time. Our data suggest that pulmonary damage and inflammation associated with HIV infection may be causative for the increased risk of lung cancer. Encouraging and assisting younger HIV-infected smokers to quit and to sustain cessation of smoking is imperative to reduce the lung cancer burden in this population.

The use of raltegravir in human immunodeficiency virus (HIV)-infected pregnant women is important in the prevention of mother-to-child HIV transmission, especially in circumstances when a rapid decline of HIV RNA load is warranted or when preferred antiretroviral agents cannot be used. Physiological changes during pregnancy can reduce antiretroviral drug exposure. We studied the effect of pregnancy on the pharmacokinetics of raltegravir and its safety and efficacy in HIV-infected pregnant women. An open-label, multicenter, phase 4 study in HIV-infected pregnant women receiving raltegravir 400 mg twice daily was performed (Pharmacokinetics of Newly Developed Antiretroviral Agents in HIV-Infected Pregnant Women Network). Steady-state pharmacokinetic profiles were obtained in the third trimester and postpartum along with cord and maternal delivery concentrations. Safety and virologic efficacy were evaluated. Twenty-two patients were included, of which 68% started raltegravir during pregnancy. Approaching delivery, 86% of the patients had an undetectable viral load (<50 copies/mL). None of the children were HIV-infected. Exposure to raltegravir was highly variable. Overall area under the plasma concentration-time curve (AUC) and plasma concentration at 12 hours after intake (C12h) plasma concentrations in the third trimester were on average 29% and 36% lower, respectively, compared with postpartum: Geometric mean ratios (90% confidence interval) were 0.71 (.53-.96) for AUC0-12h and 0.64 (.34-1.22) for C12h. The median ratio of raltegravir cord to maternal blood was 1.21 (interquartile range, 1.02-2.17; n = 9). Raltegravir was well tolerated during pregnancy. The pharmacokinetics of raltegravir showed extensive variability. The observed mean decrease in exposure to raltegravir during third trimester compared to postpartum is not considered to be of clinical importance. Raltegravir can be used in standard dosages in HIV-infected pregnant women. NCT00825929. © The Author

To determine prevalence and predictors of complementary and alternative medicine (CAM) use disclosure to health care providers and whether CAM use disclosure is associated with highly active antiretroviral therapy (HAART) adherence among HIV-infected women, we analyzed longitudinal data collected between October 1994 and March 2002 from HIV-infected CAM-using women enrolled in the Women's Interagency HIV Study. Repeated measures Poisson regression models were constructed to evaluate associations of selected predictors with CAM use disclosure and association between CAM use disclosure and HAART adherence. A total of 1,377 HIV-infected women reported CAM use during study follow-up and contributed a total of 4,689 CAM-using person visits. The overall prevalence of CAM use disclosure to health care providers was 36% across study visits. Women over 45 years old, with a college education, or with health insurance coverage were more likely to disclose their CAM use to health care providers, whereas women identified as non-Hispanic Black or other ethnicities were less likely to communicate their CAM usage. More health care provider visits, more CAM domains used, and higher health care satisfaction scores had significant relationships with increased levels of CAM use disclosure. Restricting analysis to use of herbal or nonherbal medications only, similar results were obtained. Compared to other CAM domains, mind-body practice had the lowest prevalence of CAM use disclosure. Additionally, CAM use disclosure was significantly associated with higher HAART adherence. From this study, we showed that a high percentage of HIV-infected women did not discuss their CAM use with health care providers. Interventions targeted towards both physicians and patients may enhance communication of CAM use, avoid potential adverse events and drug interactions, and enhance HAART adherence.

Aim: Prevalence of HIV among pregnant women in India is of great concern, especially to prevent HIV in children. Mother–to-child transmission of HIV is the most common cause of transmission of HIV in children. Prevalence of HIV infection in pregnant women in India has ranged from 0.7% to 1.2%. Thus, estimating prevalence of HIV in pregnant women would aid in developing and prioritizing prevention of parent-to-child transmission of HIV programs. Materials and Methods: All pregnant women referred to the antenatal clinic from 1993 onward were tested for HIV infection by ELISA test after pretest counseling. A woman was diagnosed to be HIV infected if she tested positive on more than two HIV ELISA tests. Prevalence of HIV infection in them was calculated and also whether there was an increasing trend was determined. Results: A total of 123,439 pregnant women were tested for HIV from 1993 to 2004, of which 1797 women were HIV infected. Overall, the prevalence rate was found to be 1.4%. Prevalence rose from 0.76% in 1993 to 2.37% in 1998. However, from 2004, the prevalence has decreased to 0.6%. Conclusion: Prevalence of HIV in pregnant women in Mumbai is decreasing. PMID:29302524

Objective We demonstrate the feasibility of implementing a referral and management system for cryotherapy-ineligible women in a “screen-and-treat” cervical cancer prevention program targeting HIV-infected women in Zambia. Methods We established criteria for patient referral, developed a training program for loop electrosurgical excision procedure (LEEP) providers, and adapted LEEP to a resource-constrained setting. Results We successfully trained 15 nurses to perform visual inspection with acetic acid (VIA) followed by immediate cryotherapy. Women with positive tests but ineligible for cryotherapy were referred for further evaluation. We trained four Zambian physicians to evaluate referrals, perform punch biopsy, LEEP, and manage intra-operative and post-operative complications. From January 2006 through October 2007, a total of 8823 women (41.5% HIV seropositive) were evaluated by nurses in outlying prevention clinics; of these, 1477 (16.7%) were referred for physician evaluation based on established criteria. Of the 875 (59.2% of 1147 referred) that presented for evaluation, 748 (8.4% of total screened) underwent histologic evaluation in the form of punch biopsy or LEEP. Complications associated with LEEP included anesthesia reaction (n=2) which spontaneously resolved, intra-operative (n=12) and post-operative (n=2) bleeding managed by local measures, and post-operative infection (n=12) managed with antibiotics. Conclusion With adaptations for a resource-constrained environment, we have demonstrated that performing LEEP is feasible and safe, with low rates of complications that can be managed locally. It is important to establish referral and management systems using LEEP-based excisional evaluation for women with cryotherapy-ineligible lesions in VIA-based “screen-and-treat” protocols nested within HIV-care programs in resource-constrained settings.

In the general population, lipoprotein(a) [Lp(a)] has been established as an independent causal risk factor for cardiovascular disease. Lp(a) levels are to a major extent regulated by a size polymorphism in the apolipoprotein(a) [apo(a)] gene. The roles of Lp(a)/apo(a) in human immunodeficiency virus (HIV)-related elevated cardiovascular disease risk remain unclear. The associations between total plasma Lp(a) level, allele-specific apo(a) level, an Lp(a) level carried by individual apo(a) alleles, and common carotid artery intima-media thickness were assessed in 150 HIV-infected and 100 HIV-uninfected women in the WIHS (Women's Interagency HIV Study). Linear regression analyses with and without adjustments were used. The cohort was young (mean age, ≈31 years), with the majority being Blacks (≈70%). The prevalence of a small size apo(a) (≤22 Kringle repeats) or a high Lp(a) level (≥30 mg/dL) was similar by HIV status. Total plasma Lp(a) level ( P =0.029) and allele-specific apo(a) level carried by the smaller apo(a) sizes ( P =0.022) were significantly associated with carotid artery intima-media thickness in the HIV-infected women only. After accounting for confounders (age, race, smoking, body mass index, blood pressure, hepatitis C virus coinfection, menopause, plasma lipids, treatment status, CD4 + T cell count, and HIV/RNA viral load), the association remained significant for both Lp(a) ( P =0.035) and allele-specific apo(a) level carried by the smaller apo(a) sizes ( P =0.010) in the HIV-infected women. Notably, none of the other lipids/lipoproteins was associated with carotid artery intima-media thickness. Lp(a) and allele-specific apo(a) levels predict carotid artery intima-media thickness in HIV-infected young women. Further research is needed to identify underlying mechanisms of an increased Lp(a) atherogenicity in HIV infection. © 2017 American Heart Association, Inc.

Objective To examine factors associated with HIV infection among transgender women in Cambodia. Design Cross-sectional study. Settings HIV high-burden sites including the capital city and 12 provinces. Participants This study included 1375 sexually active transgender women with a mean age of 25.9 years (SD 7.1), recruited by using respondent-driven sampling for structured questionnaire interviews and rapid finger-prick HIV testing. Primary outcome measure HIV infection detected by using Determine antibody test. Results HIV prevalence among this population was 5.9%. After adjustment for other covariates, participants living in urban areas were twice as likely to be HIV infected as those living in rural areas. Participants with primary education were 1.7 times as likely to be infected compared with those with high school education. HIV infection increased with age; compared with those aged 18–24 years, the odds of being HIV infected were twice as high among transgender women aged 25–34 years and 2.8 times higher among those aged ≥35 years. Self-injection of gender affirming hormones was associated with a fourfold increase in the odds of HIV infection. A history of genital sores over the previous 12 months increased the odds of HIV infection by threefold. Transgender women with stronger feminine identity, dressing as a woman all the time, were twice as likely to be HIV infected compared with those who did not dress as a woman all the time. Having never used online services developed for transgender women in the past six months was also associated with higher odds of being HIV infected. Conclusions Transgender women in Cambodia are at high risk of HIV. To achieve the goal of eliminating HIV in Cambodia, effective combination prevention strategies addressing the above risk factors among transgender women should be strengthened. PMID:28801398

Bagalkot district in Karnataka state is one of the highest HIV prevalence districts in India. A large proportion of the girls also marry at early age in the district and negative pregnancy outcomes among the HIV positive women likely to have large pregnancy wastages. Therefore, this study examined the pregnancy wastages and the associated factors among HIV positive women in a high prevalent district in India. We used data from a cross-sectional survey conducted recently among randomly selected currently married HIV positive women, 15-29 years of age, in one of the high HIV prevalence districts in India. The study used the experience of reported pregnancy wastage as an outcome variable, and both bi-variate and multivariate logistic regression analyses were carried out to understand the factors associated with the pregnancy wastage among HIV infected women. Overall, 17% of the respondents reported pregnancy wastage, of which 81% were due to spontaneous abortions. Respondents who became pregnant since testing HIV positive reported significantly higher level of pregnancy wastage as compared to those were pregnant before they were tested for HIV. (AOR = 1.9; p = 0.00). While a positive association between duration of marriage and pregnancy wastage was noticed (AOR = 7.4; p = 0.01), there was a negative association between number of living children and pregnancy wastage (AOR = 0.24; p = 0.00). Living in a joint family was associated with increased reporting of pregnancy wastage as compared to those living in nuclear families (AOR = 1.7; p = 0.03). HIV prevention and care programs need to consider the reproductive health needs of HIV infected married women as a priority area since large proportion of these women reported negative pregnancy outcomes. There is also a need to explore ways to raise the age at marriage in order to stop women getting married before the legal age at marriage.

Background Depression is associated with increased HIV transmission risk, increased morbidity, and higher risk of HIV-related death among HIV-infected women. Low sexual relationship power also contributes to HIV risk, but there is limited understanding of how it relates to mental health among HIV-infected women. Methods Participants were 270 HIV-infected women from the Uganda AIDS Rural Treatment Outcomes study, a prospective cohort of individuals initiating antiretroviral therapy (ART) in Mbarara, Uganda. Our primary predictor was baseline sexual relationship power as measured by the Sexual Relationship Power Scale (SRPS). The primary outcome was depression severity, measured with the Hopkins Symptom Checklist (HSCL), and a secondary outcome was a functional scale for mental health status (MHS). Adjusted models controlled for socio-demographic factors, CD4 count, alcohol and tobacco use, baseline WHO stage 4 disease, social support, and duration of ART. Results The mean HSCL score was 1.34 and 23.7% of participants had HSCL scores consistent with probable depression (HSCL>1.75). Compared to participants with low SRPS scores, individuals with both moderate (coefficient b = −0.21; 95%CI, −0.36 to −0.07) and high power (b = −0.21; 95%CI, −0.36 to −0.06) reported decreased depressive symptomology. High SRPS scores halved the likelihood of women meeting criteria for probable depression (adjusted odds ratio = 0.44; 95%CI, 0.20 to 0.93). In lagged models, low SRPS predicted subsequent depression severity, but depression did not predict subsequent changes in SPRS. Results were similar for MHS, with lagged models showing SRPS predicts subsequent mental health, but not visa versa. Both Decision-Making Dominance and Relationship Control subscales of SRPS were associated with depression symptom severity. Conclusions HIV-infected women with high sexual relationship power had lower depression and higher mental health status than women with low power

Perinatal transmission and reproductive decisions of HIV-infected women can be categorized in statistical and epidemiological terms. These reports and figures, however, do little to fully explain the complexities of human relationships, life experiences, personal and cultural influences, and situational and environmental variables that impact on the HIV-infected woman regarding reproductive decision-making. It is only with genuine attempts to understand the woman's perspective and the dynamic and unique variables that influence reproductive decision-making, as well as maintaining a non-judgmental and culturally sensitive perspective, can we hope to assist women, and society as a whole, in coming to terms with the complexities of HIV and reproductive decision-making. Further study is needed to identify factors that influence reproductive decision-making in HIV-infected women. The determinants of contraceptive use regarding demographic factors, barriers to contraceptive use, and factors that contribute to successful contraceptive use in this population must be understood if efforts to reduce the number of unplanned pregnancies are to be successful. More conclusive data are needed on the safety and efficacy of oral contraceptives in HIV-infected women as well as data that describe the effects of longer acting hormonal contraceptives such as levonorgestrel implants (Norplant; Wyeth-Ayerst, Philadelphia, PA) and injectable medroxyprogesterone acetate (Depo Provera; Upjohn Company, Kalamazoo, MI). More research is needed to determine the effects of patient education and counseling and closer follow-up on effective long-term contraception in HIV-infected women.

Some HIV sero-discordant couples are faced with the dual challenge of preventing HIV transmission to the uninfected partner and avoiding unintended pregnancy. Therefore, we hypothesized that sero-discordance is associated with dual method use at last sex. We analyzed data from a cross-sectional survey of HIV-infected men and women attending 2 ART clinics in Lilongwe, Malawi. We used Fisher's exact test and Wilcoxon rank sum to assess for associations between sero-discordance, covariates, and dual method use. Multivariable logistic regression was used to estimate the adjusted odds ratio (aOR) and 95% confidence intervals (CI) of dual method use at last sex, comparing sero-discordant to sero-concordant relationships. Separate analyses were conducted for men and women. We surveyed 253 HIV infected men, of which 44 (17.4%) were in a known sero-discordant relationship and 63 (24.9%) were utilizing dual methods at last sex. Likewise, among 302 HIV infected women surveyed, 57 (18.9%) were in a known sero-discordant relationship, and 80 (26.5%) were utilizing dual method at last sex. Sero-discordance was not significantly associated with dual method use at last sex for among HIV infected men (aOR = 0.62, 95% CI: 0.27-1.44) or women (aOR = 1.21, 95% CI: 0.59-2.47). Dual method use was low among all HIV-infected individuals, irrespective of their partner's HIV status. Given these findings, we recommend greater efforts to encourage HIV providers to counsel their patients about the importance of dual method use to prevent both unintended pregnancy and sexually transmitted infections.

An increasing number of perinatally HIV-infected women (PHIV) are reaching adulthood and becoming pregnant. Most PHIV women have been exposed to a high number of antiretroviral regimens, and they may have difficulties to achieve viral suppression. Psychosocial problems are not uncommon and could be an important barrier for treatment adherence. The effects of chronic HIV infection and long-term exposure to antiretroviral treatment of PHIV women cause concerns on the developing fetus. The aims of this study were to describe the prevention of mother-to-child transmission strategies in PHIV women and the infant outcomes in the Madrid Cohort of HIV-infected mother-infant pairs. All PHIV pregnant women registered in the Cohort that gave birth from 2000 to 2015 were included in the study. Twenty-eight pregnancies in twenty-two perinatally infected women were registered. Most women were Caucasian and heavily treatment-experienced. Nine cases (32.1%) were at high risk of HIV mother-to-child transmission. Maternal HIV-1 viral load was detectable close to delivery in four women (14.3%). The management of these cases was described, and the treatment strategies were discussed. None of the newborns acquired HIV infection. Eight infants (28.6%) were small for gestational age. This study included a large series of pregnancies among PHIV women attended according to a youth-centered care model. The challenges in the management of this population by health-care providers were described. Specific strategies to minimize perinatal transmission risks should be addressed in future collaborative studies.

Deworming human immunodeficiency virus (HIV)-infected individuals on antiretroviral therapy (ART) may be beneficial, particularly during pregnancy. We determined the efficacy of targeted and nontargeted antihelminth therapy and its effects on Plasmodium falciparum infection status, hemoglobin levels, CD4 counts, and viral load in pregnant, HIV-positive women receiving ART. Nine hundred eighty HIV-infected pregnant women receiving ART were examined at 2 visits during pregnancy and 2 postpartum visits within 12 weeks. Women were given antimalarials when malaria-positive whereas albendazole was given in a targeted (n = 467; treatment when helminth stool screening was positive) or nontargeted (n = 513; treatment at all time points, with stool screening) fashion. No significant differences were noted between targeted and nontargeted albendazole treatments for the variables measured at each study visit except for CD4 counts, which were lower (P < .05) in the latter group at the final visit. Albendazole therapy was associated with favorable changes in subjects' hemoglobin levels, CD4 counts, and viral loads, particularly with helminth infections. Antihelminthic therapy reduces detectable viral load, and increases CD4 counts and hemoglobin levels in pregnant HIV-infected women with helminth coinfections receiving ART. © The Author 2014.

The prevalence of post-traumatic stress disorder (PTSD) is higher among HIV-infected (HIV+) women compared with HIV-uninfected (HIV-) women, and deficits in episodic memory are a common feature of both PTSD and HIV infection. We investigated the association between a probable PTSD diagnosis using the PTSD Checklist-Civilian (PCL-C) version and verbal learning and memory using the Hopkins Verbal Learning Test in 1004 HIV+ and 496 at-risk HIV- women. HIV infection was not associated with a probable PTSD diagnosis (17% HIV+, 16% HIV-; p = 0.49) but was associated with lower verbal learning (p < 0.01) and memory scores (p < 0.01). Irrespective of HIV status, a probable PTSD diagnosis was associated with poorer performance in verbal learning (p < 0.01) and memory (p < 0.01) and psychomotor speed (p < 0.001). The particular pattern of cognitive correlates of probable PTSD varied depending on exposure to sexual abuse and/or violence, with exposure to either being associated with a greater number of cognitive domains and a worse cognitive profile. A statistical interaction between HIV serostatus and PTSD was observed on the fine motor skills domain (p = 0.03). Among women with probable PTSD, HIV- women performed worse than HIV+ women on fine motor skills (p = 0.01), but among women without probable PTSD, there was no significant difference in performance between the groups (p = 0.59). These findings underscore the importance of considering mental health factors as correlates to cognitive deficits in women with HIV.

Background Isolated antibody to hepatitis B core antigen (anti-HBc) is a common serologic finding in persons infected with human immunodeficiency virus (HIV), but the outcome and clinical significance are uncertain. Methods We performed repeated hepatitis B virus (HBV) serologic tests on women who participated in the Women’s Interagency HIV Study and who had isolated anti-HBc at study entry. Results Repeated serologic tests were performed for 322 women (282 HIV-infected and 40 HIV-uninfected) at a median of 7.5 years after study entry. Seventy-one percent of women retained isolated anti-HBc serologic status, 20% acquired antibody to hepatitis B surface antigen (anti-HBs), and 2% acquired hepatitis B surface antigen (HBsAg). In unadjusted analysis, increasing age, injection drug use, and hepatitis C viremia were negatively associated with acquisition of anti-HBs. For HIV-infected women, predictors of acquisition of anti-HBs were an increase in CD4 cell count and the use of highly active antiretroviral therapy (HAART). Receipt of drugs with activity against HBV and self-reported HBV vaccination did not predict anti-HBs acquisition. In the multivariable regression model, HAART use remained a significant predictor of anti-HBs acquisition, whereas women with hepatitis C viremia were more likely to retain isolated anti-HBc serologic status. Conclusions Isolated anti-HBc status remained stable over time for the majority of women, especially women with chronic hepatitis C virus infection. Development of anti-HBs was predicted by HAART use and an increase in CD4 cell count. We conclude that a proportion of HIV-infected women with isolated anti-HBc have prior natural HBV infection with anti-HBs that is at an undetectable level because of immune dysfunction. Isolated anti-HBc in the presence of chronic hepatitis C virus infection may be attributable to a different phenomenon, such as dysfunctional antibody production. PMID:19480573

Despite the major benefits of effective antiretroviral therapy on HIV-related survival, there is an ongoing need to help alleviate medication side effects related to antiretroviral therapy use. Initial studies suggest that marijuana use may reduce HIV-related symptoms, but medical marijuana use among HIV-infected individuals has not been well described. The authors evaluated trends in marijuana use and reported motivations for use among 2776 HIV-infected women in the Women's Interagency HIV Study between October 1994 and March 2010. Predictors of any and daily marijuana use were explored in multivariate logistic regression models clustered by person using generalized estimating equation. In 2009, participants were asked if their marijuana use was medical, "meaning prescribed by a doctor," or recreational, or both. Over the 16 years of this study, the prevalence of current marijuana use decreased significantly from 21% to 14%. In contrast, daily marijuana use almost doubled from 3.3% to 6.1% of all women and from 18% to 51% of current marijuana users. Relaxation, appetite improvement, reduction of HIV-related symptoms, and social use were reported as common reasons for marijuana use. In 2009, most marijuana users reported either purely medicinal use (26%) or both medicinal and recreational usage (29%). Daily marijuana use was associated with higher CD4 cell count, quality of life, and older age. Demographic characteristics and risk behaviors were associated with current marijuana use overall but were not predictors of daily use. This study suggests that both recreational and medicinal marijuana use are relatively common among HIV-infected women in the United States.

The Human Research Council's National HIV Prevalence, Incidence and Behavior Survey ranks South Africa first in HIV incidence in the world with 400,000 new infections in 2012 and found the HIV incidence rate among female youth aged 15 to 24 years to be 2.5% that year. The objective of this study was to compare the pattern and predictability of sexual activity between HIV-infected and HIV-uninfected young South African women. Sexually active young women between the ages of 16 and 21 years old completed a study survey between October 2012 and 2014 at two Desmond Tutu HIV Foundation centers. 100 young women with a mean age of 19.04 years responded to the survey. 51 women (51%) were HIV-infected and 49 were HIV-uninfected (49%). HIV-infected young women were found to be statistically less likely to have a temporal pattern to their sexual activity as compared to HIV-uninfected young women (56.9 vs. 95.9%, p<0.0001). While controlling for frequency of sex and lifetime sexual partners, HIV status remains a significant predictor of having a pattern of sexual activity (OR=16.13, p=0.0004) and a predictor of having sex on the weekend only (OR=4.41, p=0.0022). The ability to predict when sexual activity will occur enables a woman to prepare for its associated risks. HIV-uninfected young women are more likely to have a predictable pattern to their sexual activity as compared to HIV-infected young women. Knowledge of the sexual behavior patterns of this high-risk population will aid in the development of effective HIV prevention campaigns.

Subclinical mastitis is common in HIV-infected women and is a risk factor for mother-to-child transmission of HIV. The purpose of this study was to examine the effect of vitamin supplementation [vitamin A + β-carotene, multivitamins (B complex, C, and E), or multivitamins, including vitamin A + β-carotene] on the risk of subclinical mastitis during the first 2 y postpartum among HIV-infected women. The study was a randomized, placebo-controlled, clinical trial including 674 HIV-infected, antiretroviral naïve Tanzanian women who were recruited during pregnancy and followed-up after delivery. Breast milk samples were obtained approximately every 3 mo. Any subclinical mastitis was defined as a ratio of the sodium to potassium (Na:K) breast milk concentrations > 0.6 and further classified as either moderate (Na:K ≥ 0.6 and ≤ 1) or severe (Na:K > 1.0). Fifty-eight percent of women had at least 1 episode of any subclinical mastitis. Women assigned to multivitamins (B complex, C, and E) had a 33% greater risk of any subclinical mastitis (P = 0.005) and a 75% greater risk of severe subclinical mastitis (P = 0.0006) than women who received the placebo. Vitamin A + β-carotene also increased the risk of severe subclinical mastitis by 45% (P = 0.03). Among women with CD4+ T-cell counts ≥ 350 cells/μL, multivitamin intake resulted in a 49% increased risk of any subclinical mastitis (P = 0.006); by contrast, there were no treatment effects among women with CD4+ T-cell counts < 350 cells/μL (P- interaction for treatment × CD4+ T-cell count = 0.10). Supplementation of HIV-infected women with vitamins increased the risk of subclinical mastitis.

Background Falls and fall-related injuries are a major public health concern. HIV-infected adults have been shown to have a high incidence of falls. Identification of major risk factors for falls that are unique to HIV or similar to the general population will inform development of future interventions for fall prevention. Methods HIV-infected and uninfected men and women participating in a Hearing and Balance Sub-study of the Multicenter AIDS Cohort Study and Women’s Interagency HIV Study were asked about balance symptoms and falls during the prior 12 months. Falls were categorized as 0, 1, or ≥ 2; proportional odds logistic regression models were used to investigate relationships between falls and demographic and clinical variables and multivariable models were created. Results 24% of 303 HIV-infected participants reported ≥1 fall compared to 18% of 233 HIV-uninfected participants (p=0.27). HIV-infected participants were demographically different from HIV-uninfected participants, and were more likely to report clinical imbalance symptoms (p≤0.035). In univariate analyses, more falls were associated with hepatitis C, female sex, obesity, smoking, and clinical imbalance symptoms, but not age, HIV serostatus, or other comorbidities. In multivariable analyses, female sex and imbalance symptoms were independently associated with more falls. Among HIV-infected participants, smoking, number of medications, and imbalance symptoms remained independent fall predictors while current protease inhibitor use was protective. Discussion Similar rates of falls among HIV-infected and uninfected participants were largely explained by a high prevalence of imbalance symptoms. Routine assessment of falls and dizziness/imbalance symptoms should be considered, with interventions targeted at reducing symptomatology. PMID:27028463

To estimate the incidence of first pregnancy in women living with perinatally acquired HIV (PHIV) in the United Kingdom and to compare pregnancy management and outcomes with age-matched women with behaviourally acquired HIV (BHIV). The National Study of HIV in Pregnancy and Childhood is a comprehensive, population-based surveillance study that collects demographic and clinical data on all pregnant women living with HIV, their children, and all HIV-infected children in the United Kingdom and Ireland. The incident rate ratio of first pregnancy was calculated for all women of reproductive age who had been reported to the National Study of HIV in Pregnancy and Childhood as vertically infected children. These women and their pregnancies were compared to age-matched pregnant women with BHIV. Of the 630 women with PHIV reported in the United Kingdom as children, 7% (45) went on to have at least one pregnancy, with 70 pregnancies reported. The incident rate ratio of first pregnancy was 13/1000 woman-years. The BHIV comparison group comprised 118 women (184 pregnancies). Women with PHIV were more likely to be on combined antiretroviral therapy at conception and have a lower baseline CD4 cell count (P < 0.01 for both). In adjusted analysis, PHIV and a low baseline CD4 cell count were risk factors for detectable viral load near delivery; older age at conception and being on combined antiretroviral therapy at conception reduced this risk. Women with PHIV in the United Kingdom have a low pregnancy incidence, but those who become pregnant are at risk of detectable viral load near delivery, reflecting their often complex clinical history, adherence, and drug resistance issues.

Infected Lives: Lived Experiences of Young African American HIV-Positive Women.

This hermeneutic phenomenological study explored the lived experiences of young African American HIV-infected women. Eleven women between the ages of 21 and 35 participated. One pattern, Infected Lives, and three themes--Living Alone With HIV, Living With Unresolved Conflicts, and Living With Multiple Layers of Betrayal--emerged. The pattern and themes portray the very complex and challenging experiences faced by these young women living with HIV infection. They have experienced isolation, abandonment, betrayal, and discrimination in their interpersonal and social systems. They often dealt with conflicts of hope and anguish in the relationships with their children, and portraying strength, while feeling fragile. These complexities negatively influence the ability to fully engage in self-care activities. Implications for future research include further investigation about the experiences of psychological distress experienced post-diagnosis, development and evaluation of holistic nursing interventions, and evaluative research on mass media educational campaigns to reduce HIV-related stigma. © The Author(s) 2014.

Subclinical kidney disease is associated with developing hypertension in the general population, but data are lacking among HIV-infected persons. We examined associations of kidney function and injury with incident hypertension in 823 HIV-infected and 267 HIV-uninfected women in the Women’s Interagency HIV Study, a multicenter, prospective cohort of HIV-infected and uninfected women in the United States. Baseline kidney biomarkers included estimated glomerular filtration rate using cystatin C (eGFR), urine albumin-to-creatinine ratio (ACR), and seven urine biomarkers of tubular injury: alpha-1-microglobulin, interleukin-18 (IL-18), kidney injury molecule-1, neutrophil gelatinase-associated lipocalin, liver fatty acid binding protein, N-acetyl-beta-D-glucosaminidase (NAG), and alpha1-acid-glycoprotein (AAG). We used multivariable Poisson regression to evaluate associations of kidney biomarkers with incident hypertension, defined as two consecutive visits of anti-hypertensive medication use. Over a median follow-up of 9.6 years, 288 HIV-infected women (35%) developed hypertension. Among the HIV-infected women, higher ACR was independently associated with incident hypertension (RR=1.13 per ACR doubling, 95%CI: 1.07, 1.20), as was lower eGFR (RR=1.10 per 10 ml/min/1.73m2 lower eGFR, CI: 1.04, 1.17). No tubular injury and dysfunction biomarkers were independently associated with incident hypertension in HIV-infected women. In contrast, among the HIV-uninfected women, ACR was not associated with incident hypertension, whereas higher IL-18, AAG and NAG were significantly associated with incident hypertension. These findings suggest that early glomerular injury and kidney dysfunction may be involved in the pathogenesis of hypertension in HIV-infected persons. The associations of the tubular markers with hypertension in HIV-uninfected women should be validated in other studies. PMID:27993956

Limited data exist on the burden of respiratory syncytial virus (RSV) illness among pregnant women, to determine their potential benefit from RSV vaccination. We evaluated the incidence of RSV illness from midpregnancy until 24 weeks postpartum in human immunodeficiency virus (HIV)-uninfected and HIV-infected women and their infants. Mother-infant dyads were enrolled in maternal influenza vaccine efficacy trials. These included 1060 and 1056 HIV-uninfected pregnant women in 2011 and 2012, respectively, 194 HIV-infected pregnant women in 2011, and their infants. Upper respiratory tract samples obtained at illness visits were tested for RSV. The incidence (per 1000 person-months) of RSV illness (n = 43 overall) among HIV-uninfected women was lower in 2011 (1.2; 95% confidence interval [CI], .6-2.2) than in 2012 (4.0; 95% CI, 2.8-5.6). The incidence of RSV illness (n = 5) in HIV-infected women was 3.4 (95% CI, 1.4-8.1). Maternal RSV infection was associated with respiratory symptoms including cough (72.1%), rhinorrhea (39.5%), sore throat (37.2%), and headache (42%), but fever was absent. RSV infection during pregnancy was not associated with adverse pregnancy outcomes. Postpartum, RSV infection in mothers (n = 27) was associated with concurrent infection among 51.9% of their infants and, conversely, 29.8% of mothers investigated within 7 days of their infants having an RSV illness also tested positive for RSV. RSV infection is associated with respiratory illness during pregnancy and postpartum. Vaccination of pregnant women against RSV could benefit the mother, albeit primarily against nonfebrile illness, and her infant. NCT01306669 and NCT01306682.

Placental malaria among HIV-infected and uninfected women receiving anti-folates in a high transmission area of Uganda

PubMed Central

2009-01-01

Background HIV infection increases the risk of placental malaria, which is associated with poor maternal and infant outcomes. Recommendations in Uganda are for HIV-infected pregnant women to receive daily trimethoprim-sulphamethoxazole (TS) and HIV-uninfected women to receive intermittent sulphadoxine-pyrimethamine (SP). TS decreases the risk of malaria in HIV-infected adults and children but has not been evaluated among pregnant women. Methods This was a cross sectional study comparing the prevalence of placental malaria between HIV-infected women prescribed TS and HIV-uninfected women prescribed intermittent preventive therapy with sulphadoxine-pyrimethamine (IPT-SP) in a high malaria transmission area in Uganda. Placental blood was evaluated for malaria using smear and PCR. Results Placentas were obtained from 150 HIV-infected women on TS and 336 HIV-uninfected women on IPT-SP. The proportion of HIV-infected and HIV-uninfected women with placental malaria was 19% vs. 26% for those positive by PCR and 6% vs. 9% for those positive by smear, respectively. Among all infants, smear+ placental malaria was most predictive of low birth weight (LBW). Primigravidae were at higher risk than multigravidae of having placental malaria among HIV-uninfected, but not HIV-infected, women. Adjusting for gravidity, age, and season at the time of delivery, HIV-infected women on TS were not at increased risk for placental malaria compared to HIV-uninfected women on IPT-SP, regardless of the definition used. Conclusion Prevalence of placental malaria was similar in HIV-infected women on TS and HIV-uninfected women on IPT-SP. Nonetheless, while nearly all of the women in this study were prescribed anti-folates, the overall risk of placental malaria and LBW was unacceptably high. The population attributable risk of placental malaria on LBW was substantial, suggesting that future interventions that further diminish the risk of placental malaria may have a considerable impact on the

HIV-exposed infants born to depressed women may be at risk for adverse developmental outcomes. Half of HIV-infected women in rural South Africa (SA) may suffer from pregnancy-related depression. This pilot study examined the impact of depression in HIV-infected women in rural SA on infant development. Mother-infant dyads (N = 69) were recruited in rural SA. Demographics, HIV disclosure, depression, male involvement, and alcohol use at baseline (18.35 ± 5.47 weeks gestation) were assessed. Male involvement, depression, infant HIV serostatus and development were assessed 12 months postnatally. Half of the women (age = 29 ± 5) reported depression prenatally and one-third reported depression postnatally. In multivariable logistic regression, not cohabiting with their male partner, nondisclosure of HIV status, and postnatal depression predicted cognitive delay; decreased prenatal male involvement predicted delayed gross motor development (ps < 0.05). Assessing pregnancy-related depression among HIV-infected women and infant development and increasing male involvement may reduce negative developmental outcomes among HIV-exposed or infected infants.

To examine factors associated with HIV infection among transgender women in Cambodia. Cross-sectional study. HIV high-burden sites including the capital city and 12 provinces. This study included 1375 sexually active transgender women with a mean age of 25.9 years (SD 7.1), recruited by using respondent-driven sampling for structured questionnaire interviews and rapid finger-prick HIV testing. HIV infection detected by using Determine antibody test. HIV prevalence among this population was 5.9%. After adjustment for other covariates, participants living in urban areas were twice as likely to be HIV infected as those living in rural areas. Participants with primary education were 1.7 times as likely to be infected compared with those with high school education. HIV infection increased with age; compared with those aged 18-24 years, the odds of being HIV infected were twice as high among transgender women aged 25-34 years and 2.8 times higher among those aged ≥35 years. Self-injection of gender affirming hormones was associated with a fourfold increase in the odds of HIV infection. A history of genital sores over the previous 12 months increased the odds of HIV infection by threefold. Transgender women with stronger feminine identity, dressing as a woman all the time, were twice as likely to be HIV infected compared with those who did not dress as a woman all the time. Having never used online services developed for transgender women in the past six months was also associated with higher odds of being HIV infected. Transgender women in Cambodia are at high risk of HIV. To achieve the goal of eliminating HIV in Cambodia, effective combination prevention strategies addressing the above risk factors among transgender women should be strengthened. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Introduction To assess evidence of an association between intimate partner violence (IPV) and HIV infection among women. Methods Medline/PubMed, Embase, Web of Science, EBSCO, Ovid, Cochrane HIV/AIDS Group's Specialized Register and Cochrane Central Register of Controlled Trials were searched up to 20 May 2013 to identify studies that examined the association between IPV and HIV infection in women. We included studies on women aged ≥15 years, in any form of sexually intimate relationship with a male partner. Results Twenty-eight studies [(19 cross-sectional, 5 cohorts and 4 case-control studies) involving 331,468 individuals in 16 countries – the US (eight studies), South Africa (four studies), East Africa (10 studies), India (three studies), Brazil (one study) and multiple low-income countries (two studies)] were included. Results were pooled using RevMan 5.0. To moderate effect estimates, we analyzed all data using the random effects model, irrespective of heterogeneity level. Pooled results of cohort studies indicated that physical IPV [pooled RR (95% CI): 1.22 (1.01, 1.46)] and any type of IPV [pooled RR (95% CI): 1.28 (1.00, 1.64)] were significantly associated with HIV infection among women. Results of cross-sectional studies demonstrated significant associations of physical IPV with HIV infection among women [pooled OR (95% CI): 1.44 (1.10, 1.87)]. Similarly, results of cross-sectional studies indicated that combination of physical and sexual IPV [pooled OR (95% CI): 2.00 (1.24, 3.22) and any type of IPV [pooled OR (95% CI): 1.41 (1.16, 1.73)] were significantly associated with HIV infection among women. Conclusions Available evidence suggests a moderate statistically significant association between IPV and HIV infection among women. To further elucidate the strength of the association between IPV and HIV infection among women, there is a need for high-quality follow-up studies conducted in different geographical regions of the world, and among

Objective HIV infection and low CD4+ T-cell count are associated with an increased risk of persistent oncogenic HPV infection – the major risk factor for cervical cancer. Few reported prospective cohort studies have characterized the incidence of invasive cervical cancer (ICC) in HIV-infected women. Methods Data were obtained from HIV-infected and -uninfected female participants in the NA-ACCORD with no history of ICC at enrollment. Participants were followed from study entry or January, 1996 through ICC, loss-to follow-up or December, 2010. The relationship of HIV infection and CD4+ T-cell count with risk of ICC was assessed using age-adjusted Poisson regression models and standardized incidence ratios (SIR). All cases were confirmed by cancer registry records and/or pathology reports. Cervical cytology screening history was assessed through medical record abstraction. Results A total of 13,690 HIV-infected and 12,021 HIV-uninfected women contributed 66,249 and 70,815 person-years (pys) of observation, respectively. Incident ICC was diagnosed in 17 HIV-infected and 4 HIV-uninfected women (incidence rate of 26 and 6 per 100,000 pys, respectively). HIV-infected women with baseline CD4+ T-cells of ≥ 350, 200–349 and <200 cells/uL had a 2.3-times, 3.0-times and 7.7-times increase in ICC incidence, respectively, compared with HIV-uninfected women (Ptrend =0.001). Of the 17 HIV-infected cases, medical records for the 5 years prior to diagnosis showed that 6 had no documented screening, 5 had screening with low grade or normal results, and 6 had high-grade results. Conclusions This study found elevated incidence of ICC in HIV-infected compared to -uninfected women, and these rates increased with immunosuppression. PMID:23254153

Background Through implementation of combination antiretroviral therapy (cART) remarkable gains have been achieved in the management of HIV infection; nonetheless, the neurocognitive consequences of infection remain a pivotal concern in the cART era. Research has often employed norm-referenced neuropsychological scores, derived from healthy populations (excluding many seronegative individuals at high risk for HIV infection), to characterize impairments in predominately male HIV-infected populations. Methods Using matched-group methodology, we assessed 81 HIV-seropositive (HIV+) women with established neuropsychological measures validated for detection of HIV-related impairments, as well as additional detailed tests of executive function and decision-making from the Cambridge Neuropsychological Test Automated Battery (CANTAB). Results On validated tests, the HIV+ women exhibited impairments that were limited to significantly slower information processing speed when compared with 45 HIV-seronegative (HIV−) women with very similar demographic backgrounds and illness comorbidities. Additionally, select executive impairments in shifting attention (i.e., reversal learning) and in decision-making quality were revealed in HIV+ participants. Modifiers of neurocognition in HIV-infected women included detectable HIV plasma viral load, active hepatitis C virus co-infection, and self-reported depression symptoms. In contrast, leukocyte telomere length (LTL), a marker of cellular aging, did not significantly differ between HIV+ and HIV− women, nor was LTL associated with overall neurocognition in the HIV+ group. Conclusions The findings suggest that well-managed HIV infection may entail a more circumscribed neurocognitive deficit pattern than that reported in many norm-referenced studies, and that common comorbidities make a secondary contribution to HIV-related neurocognitive impairments.

To investigate the tolerability of mefloquine intermittent preventive treatment (MQ IPTp) for malaria in HIV-infected pregnant women compared with HIV-negative women. Prospective cohort study comparing samples of HIV-negative and HIV-infected pregnant women from 2 clinical trials conducted in Benin. One hundred and three HIV-infected women from the ongoing PACOME trial were compared with 421 HIV-negative women from a former trial, both trials aiming to evaluate the efficacy and tolerability of MQ IPTp, administered at the dose of 15 mg/kg. Descriptive analysis compared the proportion of women reporting at least 1 adverse reaction, according to HIV status. Multilevel logistic regression identified factors associated with the probability of reporting an adverse reaction for each MQ intake. Dizziness and vomiting were the most frequent adverse reactions. Adverse reactions were less frequent in HIV-infected women (65% versus 78%, P = 0.009). In multilevel analysis, HIV infection [odds ratio (OR) = 0.23, 95% confidence interval (CI) = 0.08 to 0.61] decreased the risk for adverse reactions, whereas detectable viral load (OR = 2.46, 95% CI = 1.07 to 5.66), first intake (versus further intakes, OR = 5.26, 95% CI = 3.70 to 7.14), older age (OR = 1.62, 95% CI = 1.13 to 2.32), and higher education level (OR = 1.71, 95% CI = 1.12 to 2.61) increased the risk. Moderate and severe adverse reactions were more frequent when antiretrovirals were started concomitantly with a MQ intake. This study provides reassuring data on the use of MQ IPTp in HIV-infected pregnant women. However frequent, adverse reactions remained moderate and did not impair adherence to MQ IPTp. In this high-risk group, MQ might be an acceptable alternative in case sulfadoxine-pyrimethamine loses its efficacy for intermittent preventive treatment.

Little is known about the impact of knowledge of HIV serostatus on pregnancy intention and contraceptive use in high-HIV-burden southern African settings in the era of widespread antiretroviral treatment availability. We analyzed interview data collected among 473 HIV-uninfected and 468 HIV-infected pregnant and recently postpartum women at two sites in southern Botswana. Participants were interviewed about their knowledge of their HIV status prior to pregnancy, intendedness of the pregnancy, contraceptive use, and future childbearing desires. The median age of the 941 women was 27 years, median lifetime pregnancies was 2, and 416 (44%) of pregnancies were unintended. Among women reporting unintended pregnancy, 36% were not using a contraceptive method prior to conception. Among contraception users, 81% used condoms, 13% oral contraceptives and 5% an injectable contraceptive. In univariable analysis, women with unintended pregnancy had a higher number of previous pregnancies (P = <0.0001), were less educated (P = 0.0002), and less likely to be married or living with a partner (P < 0.0001). Thirty-percent reported knowing that they were HIV-infected, 48% reported knowing they were HIV-uninfected, and 22% reported not knowing their HIV status prior to conception. In multivariable analysis, women who did not know their HIV status pre-conception were more likely to report their pregnancy as unintended compared to women who knew that they were HIV-uninfected (aOR = 1.7; 95%CI: 1.2-2.5). After controlling for other factors, unintended pregnancy was not associated with knowing one's HIV positive status prior to conception (compared with knowing one's negative HIV status prior to conception). Among women with unintended pregnancy, there was no association between knowing their HIV status and contraceptive use prior to pregnancy in adjusted analyses. Sixty-one percent of women reported not wanting any more children after this pregnancy, with HIV-infected women

Subclinical kidney disease is associated with developing hypertension in the general population, but data are lacking among HIV-infected people. We examined associations of kidney function and injury with incident hypertension in 823 HIV-infected and 267 HIV-uninfected women in the Women's Interagency HIV Study, a multicenter, prospective cohort of HIV-infected and uninfected women in the United States. Baseline kidney biomarkers included estimated glomerular filtration rate using cystatin C, urine albumin-to-creatinine ratio, and 7 urine biomarkers of tubular injury: α-1-microglobulin, interleukin-18, kidney injury molecule-1, neutrophil gelatinase-associated lipocalin, liver fatty acid-binding protein, N-acetyl-β-d-glucosaminidase, and α1-acid-glycoprotein. We used multivariable Poisson regression to evaluate associations of kidney biomarkers with incident hypertension, defined as 2 consecutive visits of antihypertensive medication use. During a median follow-up of 9.6 years, 288 HIV-infected women (35%) developed hypertension. Among the HIV-infected women, higher urine albumin-to-creatinine ratio was independently associated with incident hypertension (relative risk =1.13 per urine albumin-to-creatinine ratio doubling, 95% confidence interval, 1.07-1.20), as was lower estimated glomerular filtration rate (relative risk =1.10 per 10 mL/min/1.73 m 2 lower estimated glomerular filtration rate; 95% confidence interval, 1.04-1.17). No tubular injury and dysfunction biomarkers were independently associated with incident hypertension in HIV-infected women. In contrast, among the HIV-uninfected women, urine albumin-to-creatinine ratio was not associated with incident hypertension, whereas higher urine interleukin-18, α1-acid-glycoprotein, and N-acetyl-β-d-glucosaminidase levels were significantly associated with incident hypertension. These findings suggest that early glomerular injury and kidney dysfunction may be involved in the pathogenesis of hypertension in

It was to assess the quality of life (QOL) of HIV-infected pregnant women using the HIV/AIDS - Targeted Quality of Life (HAT-QoL) questionnaire. A descriptive study of 60 pregnant women attended at the Multidisciplinary Nucleus of Infectious Diseases During Pregnancy (NUPAIG) - UNIFESP/EPM and in the referral network of the Municipal Office of São Paulo, conducted from February 2011 to October 2012. Sociodemographic and clinical variables were collected from 60 HIV-infected pregnant women who answered the HAT-QoL questionnaire, which included 34 questions about quality of life. The average age was 30 years and the average period of HIV infection was 5.7 years. Only 8.3% of patients had a CD4 cell score of ≤200 cells/mm³ and 45% showed undetectable viral load. The average domain scores ranged from 47.5 to 83.7. The domains with the lowest scores were financial concerns and concerns about secrecy. The domains with the highest scores and lower impact on quality of life were concerns about medication and confidence in the professional. In this initial study with 60 pregnant women, we concluded that the HAT-QOL can contribute to the assessment of quality of life in the population of HIV-infected pregnant women in Brazil.

Preventing HIV infection without targeting the virus: how reducing HIV target cells at the genital tract is a new approach to HIV prevention.

For over three decades, HIV infection has had a tremendous impact on the lives of individuals and public health. Microbicides and vaccines studies have shown that immune activation at the genital tract is a risk factor for HIV infection. Furthermore, lower level of immune activation, or what we call immune quiescence, has been associated with a lower risk of HIV acquisition. This unique phenotype is observed in highly-exposed seronegative individuals from different populations including female sex workers from the Pumwani cohort in Nairobi, Kenya. Here, we review the link between immune activation and susceptibility to HIV infection. We also describe a new concept in prevention where, instead of targeting the virus, we modulate the host immune system to resist HIV infection. Mimicking the immune quiescence phenotype might become a new strategy in the toolbox of biomedical methods to prevent HIV infection. Clinical trial registration on clinicaltrial.gov: #NCT02079077.

Significantly elevated rates of cervical cancer and low rates of Papanicolaou (Pap) smear screening have been documented among HIV-infected women. However, little is known about women’s perceptions of cervical cancer screening utilization. Hence, this study describes barriers and facilitators related to cervical cancer screening in a sample of HIV-infected women seeking care at an integrated HIV clinic in Houston, Texas. Using an inductive qualitative methodological approach, data were obtained from five focus group discussions with a total of 33, HIV-infected women. The majority of the study sample consisted of women who self-identified as Black (69.7%), and reported heterosexual contact as the mode of HIV acquisition (75.8%). Barriers to cervical cancer screening were described as pain and discomfort associated with receiving Pap smears and subsequent procedures; lack of awareness of cervical cancer as a preventable disease; limited transportation access; and systemic issues as it relates to scheduling gynecological appointments. Facilitators were described as awareness of HIV-infected women’s increased risk of cervical cancer and strong provider-patient relationships. To address disparities in cervical cancer screening among low-income HIV-infected women, programs should capitalize on the identified facilitators and alleviate modifiable barriers using multi-level strategies.

As work begins towards the Sustainable Development Goal target of reducing the global maternal mortality ratio (MMR) to less than 70 deaths per 100,000 live births by 2030, much needs to be done in ending preventable maternal deaths. After 1990, South Africa experienced a reversal of gains in decreasing maternal mortality, with an increase in HIV-related maternal deaths. In this study, we assessed trends in maternal mortality in HIV-infected women, on a background of an evolving HIV care programme. This was a cross-sectional, retrospective record review of maternal deaths in the obstetrics unit at Chris Hani Baragwanath Academic Hospital, in Johannesburg, South Africa, a referral hospital in a high HIV prevalence setting where the prevalence among pregnant women has plateaued around 29.0% for the past decade. Trends in HIV diagnosis and management in pregnancy, and causes of maternal deaths in HIV-infected women were analysed over different time periods (1997 to 2003, 2004 to 2009, 2010 to 2012, and 2013 to 2015) reflecting major guideline changes. From January 1997 to December 2015, there were 692 maternal deaths in the obstetrics unit. Of the 490 (70.8%) maternal deaths with a documented HIV status, 335 (68.4%) were HIV-infected. A Chi-squared test for trends showed that the institutional MMR (iMMR) in women known to be HIV-infected peaked in the period 2004 to 2009 at 380 (95% CI 319 to 446) per 100,000 live births, with a decline to 267 (95% CI 198 to 353) in 2013 to 2015, p = 0.049. This decrease coincided with changes in the South African HIV management guidelines, mainly increased availability of antiretroviral therapy (ART). Non-pregnancy related infections were the leading cause of death throughout the review period, accounting for 61.5% (206/335) of deaths. Only 23.3% (78/335) of the women who died were on ART at the time of death, this in the context of advanced immune suppression and an overall median CD4 count of 136 cells/μl (interquartile ranges

Hepatitis C virus (HCV) infection is a pandemic causing disease; more than 185 million people are infected worldwide. An HCV antibody (Ab) prevalence of 6.0% was estimated in Central African countries. The study aimed at providing HCV prevalence estimates among pregnant women in Rwanda. HCV surveillance through antibody screening test among pregnant women attending antenatal clinics was performed in 30 HIV sentinel surveillance sites in Rwanda. Among 12,903 pregnant women tested at antenatal clinics, 335 (2.6% [95% Confidence Interval 2.32-2.87]) tested positive for HCV Ab. The prevalence of HCV Ab in women aged 25-49 years was 2.8% compared to 2.4% in women aged 15-24 years (aOR = 1.3; [1.05-1.59]); This proportion was 2.7% [2.37-2.94] in pregnant women in engaged in non-salaried employment compared to 1.2% [0.24-2.14] in those engaged in salaried employment (aOR = 3.2; [1.60-6.58]). The proportion of HCV Ab-positive co-infected with HIV was estimated at 3.9% (13 cases). Women in urban residence were more likely to be associated with HCV-infection (OR = 1.3; 95%CI [1.0-1.6]) compared to those living in rural setting. HCV is a public health problem in pregnant women in Rwanda. Few pregnant women were co-infected with HCV and HIV. Living in urban setting was more likely to associate pregnant women with HCV infection.

among women in the Amazonas. The low CD4 cell count was an important determinant of HPV infection and abnormal cytological findings. HPV quadrivalent vaccination used in Brazil might not offer protection for an important fraction of HPV-related disease burden in women living with HIV. This is partly explained by the high presence of non targeted vaccine HR-HPVs, such as the HPV genotype groups 56/59/66, 35/39/68 and individually HPV-52 and HPV-45, some of which contribute to high-grade lesion.

Vulnerability of women in southern Africa to infection with HIV: biological determinants and priority health sector interventions.

To review biomedical determinants of women's vulnerability to infection with HIV and interventions to counter this, within the southern African context. Apart from number of exposures, if any, several factors influence the efficiency of HIV transmission during sex. Acute HIV infection, with extraordinarily high semen viral load, in conjunction with concurrent partnerships maximizes this efficiency. Delaying sexual debut and avoiding HIV exposure among biologically and socially vulnerable youth is critical. Reducing unintended pregnancies keeps girls in school and prevents vertical (also possibly horizontal) transmission. Female condoms, especially newer versions, are an under-exploited prevention technology. Control of sexually transmitted infections (STI), which facilitate HIV acquisition and transmission, remains important, especially among the most at-risk populations. Pathogens, such as herpes simplex virus type 2, which contribute most to HIV transmission in southern Africa must be targeted, although the importance of bacterial vaginosis and Trichomonas vaginalis is under-recognized. Also, heavy episodic alcohol use affects sexual decision-making and condom skills. Moreover, prevailing social contexts, partly a consequence of poor leadership, constrain the behavioural 'choices' available for girls and women. Priority health sector interventions for preventing HIV are: male and female condom programming; prevention and control of STI; outreach to most vulnerable populations; HIV testing in all patient-provider encounters; male circumcision; and the integration of HIV prevention within sexual and reproductive health services. Future interventions during acute HIV infection and microbicides will reduce women's biological vulnerability. Far-reaching measures, such as sexual equity and alcohol control, create conditions necessary for achieving sustained prevention results. These are, however, contingent on stronger, more informed cultural and political leadership.

Objectives Although haematological abnormalities are common manifestations of HIV infection, few studies on haematological parameters in HIV-infected persons have been undertaken in sub-Saharan Africa. The authors assessed factors associated with haematological parameters in HIV-infected antiretroviral-naïve and HIV-uninfected Rwandan women. Study design Cross-sectional analysis of a longitudinal cohort. Setting Community-based women's associations. Participants 710 HIV-infected (HIV+) antiretroviral-naïve and 226 HIV-uninfected (HIV−) women from the Rwanda Women's Interassociation Study Assessment. Haematological parameters categorised as (abnormal vs normal) were compared by HIV status and among HIV+ women by CD4 count category using proportions. Multivariate logistic regression models using forward selection were fit. Results Prevalence of anaemia (haemoglobin (Hb) <12.0 g/dl) was higher in the HIV+ group (20.5% vs 6.3%; p<0.001), and increased with lower CD4 counts: ≥350 (7.6%), 200–349 (16%) and <200 cells/mm3 (32.2%). Marked anaemia (Hb <10.0 g/dl) was found in 4.2% of HIV+ and none of the HIV− women (p<0.001), and was highest in HIV+ women with CD4 <200 cells/mm3 (8.4%). The HIV+ were more likely than HIV− women (4.2 vs 0.5%, respectively, p=0.002) to have moderate neutropenia with white blood cells <2.0×103 cells/mm3 and 8.4% of HIV+ women with CD4 <200 cells/mm3 had moderate neutropenia. In multivariate logistic regression analysis, BMI (OR 0.87/kg/m2, 95% CI 0.82 to 0.93; p<0.001), CD4 200–350 vs HIV− (OR 3.59, 95% CI 1.89 to 6.83; p<0.001) and CD4 <200 cells/mm3 vs HIV− (OR 8.09, 95% CI 4.37 to 14.97; <0.001) had large independent associations with anaemia. There were large independent associations of CD4 <200 cells/mm3 vs HIV− (OR 7.18, 95% CI 0.78 to 65.82; p=0.081) and co-trimoxazole and/or dapsone use (OR 5.69, 95% CI 0.63 to 51.45; p=0.122) with moderate neutropenia.

Objectives To assess incidence of, and risk factors for abnormal anal cytology and anal intraepithelial neoplasia (AIN) 2–3 in HIV-infected women. Study Design This prospective study assessed 100 HIV-infected women with anal and cervical specimens for cytology and high risk HPV testing over three semi-annual visits. Results Thirty-three women were diagnosed with an anal cytologic abnormality at least once. Anal cytology abnormality was associated with current CD4 count <200 cells/mm3, anal HPV infection and history of other sexually transmitted infections (STIs). Twelve subjects were diagnosed with AIN2-3: four after AIN1 diagnosis and four after ≥1 negative anal cytology. AIN2-3 trended towards an association with history of cervical cytologic abnormality and history of STI. Conclusions Repeated annual anal cytology screening for HIV-infected women, particularly for those with increased immunosuppression, anal and/or cervical HPV, history of other STIs, or abnormal cervical cytology, will increase the likelihood of detecting AIN2-3.

To compare the presence and quantity of cervicovaginal HIV among HIV seropositive women with clinical herpes, subclinical HSV-2 infection and without HSV-2 infection respectively; to evaluate the association between cervicovaginal HIV and HSV shedding; and identify factors associated with quantity of cervicovaginal HIV. Four groups of HIV seropositive adult female barworkers were identified and examined at three-monthly intervals between October 2000 and March 2003 in Mbeya, Tanzania: (1) 57 women at 70 clinic visits with clinical genital herpes; (2) 39 of the same women at 46 clinic visits when asymptomatic; (3) 55 HSV-2 seropositive women at 60 clinic visits who were never observed with herpetic lesions; (4) 18 HSV-2 seronegative women at 45 clinic visits. Associations of genital HIV shedding with HIV plasma viral load (PVL), herpetic lesions, HSV shedding and other factors were examined. Prevalence of detectable genital HIV RNA varied from 73% in HSV-2 seronegative women to 94% in women with herpetic lesions (geometric means 1634 vs 3339 copies/ml, p = 0.03). In paired specimens from HSV-2 positive women, genital HIV viral shedding was similar during symptomatic and asymptomatic visits. On multivariate regression, genital HIV RNA (log10 copies/mL) was closely associated with HIV PVL (β = 0.51 per log10 copies/ml increase, 95%CI:0.41-0.60, p<0.001) and HSV shedding (β = 0.24 per log10 copies/ml increase, 95% CI:0.16-0.32, p<0.001) but not the presence of herpetic lesions (β = -0.10, 95%CI:-0.28-0.08, p = 0.27). HIV PVL and HSV shedding were more important determinants of genital HIV than the presence of herpetic lesions. These data support a role of HSV-2 infection in enhancing HIV transmissibility.

Stigma has become a gendered phenomenon that affects increasing numbers of HIV-infected women worldwide. This study examined the role of age as a possible moderator of the relationship between stigma and antiretroviral therapy adherence, CD4% and viral load among 120 HIV-infected women. A secondary analysis was conducted using data from the Keeping Healthy and Active with Risk Reduction and Medication Adherence (KHARMA) Project, an National Institutes of Health (NIH) funded randomized controlled trial to improve Antiretroviral treatment (ART) adherence and reduce risky behaviors in HIV-infected women at five clinical sites in a South-eastern city from 2005 to 2008. Stigma was measured using the Perceived Personal Stigma of Human Immunodeficiency Virus and Acquired Immune Deficiency Syndrome (HIV/AIDS) scale. Among participants <50 years old (n=90), age was significantly associated with viral load (rho=-.24, p=.02) and stigma was negatively associated with CD4% (r =-.26, p=.02). For the 30 participants >50 years old, age was not significantly associated with viral load, stigma or CD4%, and there was no significant association between stigma and CD4% (r=.07, p=.70). These findings indicate the need for further study regarding this potential moderating effect and possible interventions to address the susceptibility of younger women to the harmful effects of stigma.

To determine adherence to dual contraception using depot-medroxyprogesterone acetate (DMPA) and condom among HIV-infected women. A cross-sectional study carried out from December 2013 to September 2014 at a local reference center, with application of questionnaire elaborated after Delphi panel and content validation to 114 HIV(+) women aged 15 to 49 years, using DMPA plus condom for contraception. Mean age was 33.2 ± 7.2 years, mean time since HIV detection was 8.1 ± 5.2 years, mean time of antiretroviral use was 6.8 ± 5 years and mean CD4 cells/mm3 count was 737.6 ± 341.1. Sexual HIV acquisition was reported by 98.2% (112/114), antiretroviral use by 85.9% (98/114), and 77.7% (84/114) had a CD4>500/mm3 count. Having a single sex partner was reported by 78.9% (90/114), with HIV serodiscordance in 41.2% (47/114) of couples, 21.9% did not know the serological status of their partner and in 37.7% of cases (43/114) the partner was unaware of the HIV(+) status of the woman. The last pregnancy was unplanned in 71.9% of cases (82/114) and 14.9% of the women had become pregnant the year before, with pregnancy being unplanned in 70.5% (12/17) of cases. Current use of DMPA was reported by 64.9% (74/114), with genital bleeding in 48.2% (55/114) and weight gain in 67.5% (77/114). Use of a male condom was reported by 62.2% of the subjects (71/114). Three reported that they always used a female condom and ten that they eventually used it. Unprotected vaginal sex was reported by 37.7% (43/114) and unprotected anal intercourse was reported by 32.4% (37/114). Partner resistance to use a condom occurred in 30.7% of cases (35/114). Dual contraception using DMPA with condom was reported by 42.9% (49/114). A partner who resisted wearing a condom was associated with poor adhesion (PR=0.3; 95%CI 0.2-0.7; p<0.001). A partner who was unaware that a woman was infected with HIV favored adherence (PR=1.8; 95%CI 1.2-2.7; p=0.013). The percentage of dual contraception using DMPA plus condom

This descriptive study sought to identify factors that influence HIV-infected women's intent to get pregnant. Interviews were conducted with a convenience sample of n = 322 HIV-infected women at risk for pregnancy. Participants were predominantly African-American (84.4%), single (57.9%), and ranged in age from 17 to 48 years. Forty per cent (n = 128) of the women had been pregnant since becoming HIV-positive. Potential factors influencing intent to get pregnant that were examined included demographic characteristics, HIV-related factors and personal beliefs and attitudes. In simple logistic regression models, younger age, increased motivation for child bearing, decreased perceived threat of HIV, decreased HIV symptomatology, higher traditional gender role orientation, and greater avoidance coping were all associated with greater intent to get pregnant. Following a model selection procedure, motivation for child bearing (OR = 16.05, 95% CI 7.95, 30.41) and traditional sex roles (OR = 4.49, 95% CI 1.44, 13.55) were significantly associated with greater intent to get pregnant. Traditional gender role orientation and motivation for childbearing are significant factors in predicting intent to get pregnant among HIV-infected women. These factors, as well as other non HIV-related factors, need to be routinely assessed by health care providers in developing plans of care for HIV-infected women.

FIB-4 represents a noninvasive, composite index that is a validated measure of hepatic fibrosis, which is an important indicator of liver disease. To date, there are limited data regarding hepatic fibrosis in women. FIB-4 was evaluated in a cohort of 1227 women, and associations were evaluated in univariate and multivariate regression models among 4 groups of subjects classified by their human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection status. The median FIB-4 scores were 0.60 in HIV-/HCV- women, 0.83 in HIV-/HCV+ women, 0.86 in HIV+/HCV- women, and 1.30 in HIV+/HCV+ women. In the HIV/HCV co-infected group, multivariate analysis showed that CD4(+) cell count and albumin level were negatively associated with FIB-4 (P <.0001), whereas antiretroviral therapy (ART) was positively associated with FIB-4 score (P =.0008). For the HIV mono-infected group, multivariate analysis showed that CD4(+) cell count (P <.0001) and albumin level (P =.0019) were negatively correlated with FIB-4 score, ART was positively associated with FIB-4 score (P =.0008), and plasma HIV RNA level was marginally associated with FIB-4 score (P =.080). In 72 HIV mono-infected women who were also hepatitis B surface antigen negative, ART naive, and reported no recent alcohol intake, plasma HIV RNA level was associated with increased FIB-4 score (P =.030). HIV RNA level was associated with increased FIB-4 score in the absence of hepatitis B, hepatitis C, ART, or alcohol use, suggesting a potential relationship between HIV infection and hepatic fibrosis in vivo. A better understanding of the various demographic and virologic variables that contribute to hepatic fibrosis may lead to more effective treatment of HIV infection and its co-morbid conditions.

HIV-infected prisoners in Malaysia represent a critical target population for secondary HIV risk reduction interventions and care. We report on the process and outcome of our formative research aimed at systematically selecting and adapting an EBI designed to reduce secondary HIV risk and improve adherence to antiretroviral therapy among soon-to-be-released HIV-infected prisoners. Our formative work involved a critical examination of established EBIs and associated published reports complemented by data elicited through structured interviews and focus groups with key stakeholders, members of the target population, and their family members. Based on all information, we adapted the Holistic Health Recovery Program targeting people living with HIV (HHRP+), an EBI, to consist of eight 2-hour sessions that cover a range of specified topics so that participants may individually apply intervention content as needed to accommodate their particular substance abuse, HIV risk, and antiretroviral adherence issues. This study provides a complete example of the process of selecting and adapting an EBI—taking into account both empirical evidence and input from target organization stakeholders and target population members and their families—for use in real world prison settings where high-risk populations are concentrated.

Subclinical mastitis is common in HIV-infected women and is a risk factor for mother-to-child transmission of HIV. The purpose of this study was to examine the effect of vitamin supplementation [vitamin A + β-carotene, multivitamins (B complex, C, and E), or multivitamins, including vitamin A + β-carotene] on the risk of subclinical mastitis during the first 2 y postpartum among HIV-infected women. The study was a randomized, placebo-controlled, clinical trial including 674 HIV-infected, antiretroviral naïve Tanzanian women who were recruited during pregnancy and followed-up after delivery. Breast milk samples were obtained approximately every 3 mo. Any subclinical mastitis was defined as a ratio of the sodium to potassium (Na:K) breast milk concentrations > 0.6 and further classified as either moderate (Na:K ≥ 0.6 and ≤ 1) or severe (Na:K > 1.0). Fifty-eight percent of women had at least 1 episode of any subclinical mastitis. Women assigned to multivitamins (B complex, C, and E) had a 33% greater risk of any subclinical mastitis (P = 0.005) and a 75% greater risk of severe subclinical mastitis (P = 0.0006) than women who received the placebo. Vitamin A + β-carotene also increased the risk of severe subclinical mastitis by 45% (P = 0.03). Among women with CD4+ T-cell counts ≥ 350 cells/μL, multivitamin intake resulted in a 49% increased risk of any subclinical mastitis (P = 0.006); by contrast, there were no treatment effects among women with CD4+ T-cell counts < 350 cells/μL (P- interaction for treatment × CD4+ T-cell count = 0.10). Supplementation of HIV-infected women with vitamins increased the risk of subclinical mastitis. PMID:20739447

Theory predicts that land ownership empowers women to avoid HIV acquisition by reducing their reliance on risky survival sex and enhancing their ability to negotiate safer sex. However, this prediction has not been tested empirically. Using a sample of 5511 women working in the agricultural sector from the 1998, 2003 and 2008-09 Kenya Demographic and Health Surveys, we examined the relationship between women's land ownership and participation in transactional sex, multiple sexual partnerships and unprotected sex, and HIV infection status. We controlled for demographic characteristics and household wealth, using negative binomial and logistic regression models. Women's land ownership was associated with fewer sexual partners in the past year (incidence rate ratio, 0.98; 95% confidence interval [CI], 0.95-1.00) and lower likelihood of engaging in transactional sex (odds ratio [OR], 0.67; 95% CI: 0.46-0.99), indicators of reduced survival sex, but was not associated with unprotected sex with casual partners (OR, 0.64; 95% CI, 0.35-1.18) or with unprotected sex with any partner among women with high self-perceived HIV risk (OR, 1.02; 95% CI, 0.57-1.84), indicating no difference in safer sex negotiation. Land ownership was also associated with reduced HIV infection among women most likely to engage in survival sex, i.e., women not under the household headship of a husband (OR, 0.40; 95% CI, 0.18-0.89), but not among women living in husband-headed households, for whom increased negotiation for safer sex would be more relevant (OR, 1.74; 95% CI, 0.92-3.29). These findings suggest that reinforcing women's land rights may reduce reliance on survival sex and serve as a viable structural approach to HIV prevention, particularly for women not in a husband's household, including unmarried women and female household heads.

To investigate changes over a decade in prevalence and correlates of HIV among high-risk women attending sexually transmitted infection (STI) clinics in Pune, India, who deny a history of commercial sex work (CSW). Cross-sectional. From 1993 to 2002, 2376 women attending 3 STI clinics in Pune were offered HIV screening. Women who denied CSW were included (n = 1020). Of 1020 women, 21% were HIV infected. The annual HIV prevalence increased from 14% in 1993 to 29% in 2001-2002 (P < 0.001). The change in HIV prevalence over time was paralleled by changes in clinic visitor characteristics; in later periods, women were older, more often employed, less likely to be currently married, and more likely to report condom use. In multivariate analysis, factors independently associated with HIV were calendar period (adjusted odds ratio [AOR], 1.9 for 1997-1999 vs. 1993-1996; 95% CI, 1.2-3.0; AOR, 2.3 for 2000-2002 vs. 1993-1996; 95% CI, 1.5-3.6), lack of formal education (AOR, 2.0; 95% CI, 1.4-2.9), having been widowed (AOR, 3.1; 95% CI, 1.6-6.1), current employment (AOR, 1.8; 95% CI, 1.2-2.6), and genital ulcer disease on examination (AOR, 1.8; 95% CI, 1.2-2.7). Women attending STI clinics in India who deny a history of CSW represent a small, hidden subgroup, likely put at risk for HIV because of high-risk behavior of their male partners, generally their husbands. Educational and awareness efforts that have targeted other subgroups in India (men and CSWs) should also focus on these hard-to-reach women. Risk reduction in this subgroup of Indian women would also be expected to reduce perinatal infections in India.

To assess the impact of HIV infection on the reliability of the first-trimester screening for Down syndrome, using free beta-human chorionic gonadotrophin, pregnancy-associated plasma protein-A and fetal nuchal translucency, and of the second-trimester screening for neural tube defects, using alpha-fetoprotein. Multicentre study comparing the multiples of the median of markers for Down syndrome and neural tube defect screening among 214 HIV-infected pregnant women and 856 HIV-negative controls undergoing a first-trimester Down syndrome screening test, and 209 HIV-positive women and 836 HIV-negative controls with a risk evaluation for neural tube defect. The influence of treatment, chronic hepatitis and HIV disease characteristics were also evaluated. Multiples of the median medians for pregnancy-associated plasma protein-A and beta-human chorionic gonadotrophin were lower in HIV-positive women than controls (0.88 vs. 1.05 and 0.84 vs. 1.09, respectively; P < 0.005), but these differences had no impact on risk estimation; no differences were observed for the other markers. No association was found between HIV disease characteristics, antiretroviral treatment use at the time of screening or chronic hepatitis and marker levels. Screening for Down syndrome during the first trimester and for neural tube defect during the second trimester is accurate for HIV-infected women and should be offered, similar to HIV-negative women.

BACKGROUND Sexually transmitted infections (STIs) in pregnancy such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) may lead to adverse infant outcomes. METHODOLOGY Individual urine specimens from HIV-infected pregnant women diagnosed with HIV during labor were collected at the time of infant birth and tested by polymerase chain reaction for CT and NG. Infant HIV infection was determined at 3 months with morbidity/mortality assessed through 6 months. RESULTS Of 1373 maternal urines, 277 (20.2%) were positive for CT and/or NG; 249 (18.1%) for CT, 63 (4.6%) for NG, and 35 (2.5%) for both CT and NG. HIV infection was diagnosed in 117 (8.5%) infants. Highest rates of adverse outcomes (sepsis, pneumonia, congenital syphilis, septic arthritis, conjunctivitis, low birth weight, preterm delivery, death) were noted in infants of women with CT and NG (23/35, 65.7%) compared to NG (16/28, 57.1%), CT (84/214, 39.3%), and no STI (405/1096, 37%, p=0.001). Death (11.4% vs. 3%, p=0.02), low birth weight (42.9% vs. 16.9%, p=0.001), and preterm delivery (28.6% vs. 10.2%, p=0.008) were higher among infants of CT and NG co-infected women. Infants who had any adverse outcome and were born to women with CT and/or NG were 3.5 times more likely to be HIV-infected after controlling for maternal syphilis (OR 3.5, 95% CI 1.4-8.3). By adjusted multivariate logistic regression, infants born to mothers with any CT and/or NG were 1.35 times more likely to have an adverse outcome (OR 1.35, 95% CI 1.03-1.76). CONCLUSION STIs in HIV-infected pregnant women are associated with adverse outcomes in HIV-exposed infected and uninfected infants. PMID:27164464

Prevention of unintended pregnancies among women living with HIV infection is a strategy recommended by the World Health Organization for prevention of mother-to-child transmission of HIV (PMTCT). We assessed pregnancy intentions and contraceptive use among HIV-positive and HIV-negative women with a recent pregnancy in Zimbabwe. We analyzed baseline data from the evaluation of Zimbabwe's Accelerated National PMTCT Program. Eligible women were randomly sampled from the catchment areas of 157 health facilities offering PMTCT services in five provinces. Eligible women were ≥16 years old and mothers of infants (alive or deceased) born 9 to 18 months prior to the interview. Participants were interviewed about their HIV status, intendedness of the birth, and contraceptive use. Of 8,797 women, the mean age was 26.7 years, 92.8% were married or had a regular sexual partner, and they had an average of 2.7 lifetime births. Overall, 3,090 (35.1%) reported that their births were unintended; of these women, 1,477 (47.8%) and 1,613 (52.2%) were and were not using a contraceptive method prior to learning that they were pregnant, respectively. Twelve percent of women reported that they were HIV-positive at the time of the survey; women who reported that they were HIV-infected were significantly more likely to report that their pregnancy was unintended compared to women who reported that they were HIV-uninfected (44.9% vs. 33.8%, p<0.01). After adjustment for covariates, among women with unintended births, there was no association between self-reported HIV status and lack of contraception use prior to pregnancy. Unmet need for family planning and contraceptive failure contribute to unintended pregnancies among women in Zimbabwe. Both HIV-infected and HIV-uninfected women reported unintended pregnancies despite intending to avoid or delay pregnancy, highlighting the need for effective contraceptive methods that align with pregnancy intentions.

Introduction HIV and syphilis during pregnancy remain a public health concern especially in developing countries. Pregnant women attending antenatal clinics sites for the first time between September and December 2011 and who accepted to participate in the study were enrolled. The objective was to estimate the syphilis and HIV infection rate in this population. Methods A study was conducted in 44 selected ANCs from 12 departments (5 urban and 7 rural). Pregnant women who accepted to participate in the study, attending selected sentinel ANCs sites for the first time between September and December 2011 were enrolled. To detect HIV antibodies, two consecutive ELISA assays were used (Genscreen Ultra HIV Ag/Ac, (BioRad, France) and Enzygnostic Intergral II (Siemens, GMBH, Marbug-Germany). In case of discordant results, the Western blot test II, HIV1 and 2 (Bio-Rad, Marne la Coquette, France) was used as the reference method. The RPR (Bio-Scan, Karnataka, India) test was performed to detect syphilis infection. The RPR positive results were confirmed using the TPHA test (Biotech, Cambridge, UK). Data were analyzed using SPSS 17.0 software. Results A total of 2979 pregnant women attending ANCs were enrolled. The global HIV infection rate was estimated to be 3.6% (CI: 95%; 3.0-4.4). As expected, HIV prevalence was significantly higher in women aged above 25 years (4.4% (3.4-5.6), p = 0.026) and those attending urban ANCs (5.04%, p < 0.01). Also, women living in the urban area are more at risk to be infected (5.04 VS 2.38, p < 0.01). The RPR test was positive in 117 pregnant women (3.92%). The risk for syphilis occurrence was significantly higher among the single women compared to the married ones (4.4% VS 2.7%; p < 0.01). It was also estimated that the HIV and syphilis coinfection occurred in 22 cases (0.73%). Conclusion The prevalence's of syphilis and HIV were relatively low. Marital status and sentinel site location were a risk factor associated with HIV and syphilis

While Human Immunodeficiency Virus (HIV) infections are reducing in incidence with the advent of Highly Active Anti-retroviral Therapy (HAART), there remain a number of challenges including the existence of reservoirs, drug resistance and anatomical barriers to antiretroviral therapy. To overcome these, smart nanoparticles with stimuli responsive release are proposed for delivery of anti-retroviral agents. The paper highlights the strategic similarities between the design of smart antiretroviral nanocarriers and those optimized for cancer chemotherapy. This includes the development of nanoparticles capable of passive and active targeting as well as those that are responsive to various internal and external triggers. For antiretroviral therapy, the relevant triggers for stimuli responsive release of drugs include semen, enzymes, endosomal escape, temperature and magnetic field. Deriving from the experience of cancer chemotherapy, additional potential triggers are light and ultrasound which remain hitherto unexplored in HIV therapy. In addition, the roles of nanomicrobicides (nanogels) and virus mimetic nanoparticles are discussed from the point of view of prevention of HIV transmission. The challenges associated with translation of smart nanoparticles for HIV infections to realize the Millennium Development Goal of combating HIV infections are discussed.

Cervical cancer is the second commonest cancer in women worldwide and the commonest cancer among women in Uganda. Annual cervical screening is recommended for women living with HIV for early detection of abnormal cervical changes, however uptake remains grossly limited. This study assessed factors associated with cervical screening uptake among HIV infected women at Mildmay Uganda where cervical screening using Visual inspection with acetic acid and iodine (VIA and VILI) was integrated into HIV care since July 2009. Eighteen (18) in-depth interviews with HIV infected women and 6 key informant interviews with health care providers were conducted in April 2013 to assess client, health care provider and facility-related factors that affect cervical screening uptake. In-depth interview respondents included six HIV infected women in each of the following categories; women who had never screened, those who had screened once and missed follow-up annual screening, and those who had fully adhered to the annual screening schedule. Data was analyzed using content analysis method. Motivations for cervical cancer screening included the need for comprehensive assessment, diagnosis, and management of all ailments to ensure good health, fear of consequences of cervical cancer, suspicion of being at risk and the desire to maintain a good relationship with health care workers. The following factors negatively impacted on uptake of cervical screening: Myths and misconceptions such as the belief that a woman's ovaries and uterus could be removed during screening, fear of pain associated with cervical screening, fear of undressing and the need for women to preserve their privacy, low perceived cervical cancer risk, shortage of health workers to routinely provide cervical cancer education and screening, and competing priorities for both provider and patient time. Major barriers to repeat screening included limited knowledge and appreciation of the need for repeat screening, and lack of

While the association between smoking and HPV infection, cervical cancer, and anal cancer has been well studied, evidence on the association between cigarette smoking and anal warts is limited. The purpose of this study was to investigate if cigarette smoking status influences the size of anal warts over time in HIV-infected women in a sample of 976 HIV-infected women from the Women’s Interagency HIV Study (WIHS). A linear mixed model was used to determine the effect of smoking on anal wart size. Even though women who were currently smokers had larger anal warts at baseline and slower growth rate of anal wart size after each visit than women who were not current smokers, there was no association between size of anal wart and current smoking status over time. Further studies on the role of smoking and interaction between smoking and other risk factors, however, should be explored. PMID:23155099

Design Four groups of HIV seropositive adult female barworkers were identified and examined at three-monthly intervals between October 2000 and March 2003 in Mbeya, Tanzania: (1) 57 women at 70 clinic visits with clinical genital herpes; (2) 39 of the same women at 46 clinic visits when asymptomatic; (3) 55 HSV-2 seropositive women at 60 clinic visits who were never observed with herpetic lesions; (4) 18 HSV-2 seronegative women at 45 clinic visits. Associations of genital HIV shedding with HIV plasma viral load (PVL), herpetic lesions, HSV shedding and other factors were examined. Results Prevalence of detectable genital HIV RNA varied from 73% in HSV-2 seronegative women to 94% in women with herpetic lesions (geometric means 1634 vs 3339 copies/ml, p = 0.03). In paired specimens from HSV-2 positive women, genital HIV viral shedding was similar during symptomatic and asymptomatic visits. On multivariate regression, genital HIV RNA (log10 copies/mL) was closely associated with HIV PVL (β = 0.51 per log10 copies/ml increase, 95%CI:0.41–0.60, p<0.001) and HSV shedding (β = 0.24 per log10 copies/ml increase, 95% CI:0.16–0.32, p<0.001) but not the presence of herpetic lesions (β = −0.10, 95%CI:−0.28–0.08, p = 0.27). Conclusions HIV PVL and HSV shedding were more important determinants of genital HIV than the presence of herpetic lesions. These data support a role of HSV-2 infection in enhancing HIV transmissibility. PMID:23516595

Programs for integration of family planning into HIV care must recognize current practices and desires among clients to appropriately target and tailor interventions. We sought to evaluate fertility intentions, unintended pregnancy, contraceptive and condom use among a cohort of HIV-infected women seeking family planning services within an antiretroviral therapy (ART) clinic. 200 women completed an interviewer-administered questionnaire during enrollment into a prospective contraceptive study at the Lighthouse Clinic, an HIV/ART clinic in Lilongwe, Malawi, between August and December 2010. Most women (95%) did not desire future pregnancy. Prior reported unintended pregnancy rates were high (69% unplanned and 61% unhappy with timing of last pregnancy). Condom use was inconsistent, even among couples with discordant HIV status, with lack of use often attributed to partner's refusal. Higher education, older age, lower parity and having an HIV negative partner were factors associated with consistent condom usage. High rates of unintended pregnancy among these women underscore the need for integ rating family planning, sexually transmitted infection (STI) prevention, and HIV services. Contraceptive access and use, including condoms, must be improved with specific efforts to enlist partner support. Messages regarding the importance of condom usage in conjunction with more effective modern contraceptive methods for both infection and pregnancy prevention must continue to be reinforced over the course of ongoing ART treatment.

Background. Bacterial vaginosis (BV) is characterized by low abundance of Lactobacillus species, high pH, and immune cell infiltration and has been associated with an increased risk of human papillomavirus (HPV) infection. We molecularly assessed the cervicovaginal microbiota over time in human immunodeficiency virus (HIV)–infected and HIV-uninfected women to more comprehensively study the HPV-microbiota relationship, controlling for immune status. Methods. 16S ribosomal RNA gene amplicon pyrosequencing and HPV DNA testing were conducted annually in serial cervicovaginal lavage specimens obtained over 8–10 years from African American women from Chicago, of whom 22 were HIV uninfected, 22 were HIV infected with a stable CD4+ T-cell count of > 500 cells/mm3, and 20 were HIV infected with progressive immunosuppression. Vaginal pH was serially measured. Results. The relative abundances of Lactobacillus crispatus and other Lactobacillus species were inversely associated with vaginal pH (all P < .001). High (vs low) L. crispatus relative abundance was associated with decreased HPV detection (odds ratio, 0.48; 95% confidence interval, .24–.96; Ptrend = .03) after adjustment for repeated observation and multiple covariates, including pH and study group. However, there were no associations between HPV and the relative abundance of Lactobacillus species as a group, nor with Lactobacillus gasseri, Lactobacillus iners, and Lactobacillus jensenii individually. Conclusions. L. crispatus may have a beneficial effect on the burden of HPV in both HIV-infected and HIV-uninfected women (independent of pH). PMID:27521363

Sexually transmitted infections (STIs) in pregnancy such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) may lead to adverse infant outcomes. Individual urine specimens from HIV-infected pregnant women diagnosed with HIV during labor were collected at the time of infant birth and tested by polymerase chain reaction for CT and NG. Infant HIV infection was determined at 3 months with morbidity/mortality assessed through 6 months. Of 1373 maternal urine samples, 277 (20.2%) were positive for CT and/or NG; 249 (18.1%) for CT, 63 (4.6%) for NG and 35 (2.5%) for both CT and NG. HIV infection was diagnosed in 117 (8.5%) infants. Highest rates of adverse outcomes (sepsis, pneumonia, congenital syphilis, septic arthritis, conjunctivitis, low birth weight, preterm delivery and death) were noted in infants of women with CT and NG (23/35, 65.7%) compared with NG (16/28, 57.1%), CT (84/214, 39.3%) and no STI (405/1096, 37%, P = 0.001). Death (11.4% vs. 3%, P = 0.02), low birth weight (42.9% vs. 16.9%, P = 0.001) and preterm delivery (28.6% vs. 10.2%, P = 0.008) were higher among infants of CT and NG-coinfected women. Infants who had any adverse outcome and were born to women with CT and/or NG were 3.5 times more likely to be HIV infected after controlling for maternal syphilis (odds ratio: 3.5, 95% confidence interval: 1.4-8.3). By adjusted multivariate logistic regression, infants born to mothers with any CT and/or NG were 1.35 times more likely to have an adverse outcome (odds ratio, 1.35; 95% confidence interval, 1.03-1.76). STIs in HIV-infected pregnant women are associated with adverse outcomes in HIV-exposed infected and uninfected infants.

Linear growth retardation and wasting are common in children born to HIV-infected women. Inexpensive interventions that could improve the postnatal growth pattern of such children are needed. The objective was to examine the effect of supplementing HIV-infected women with multivitamins or vitamin A and beta-carotene, during and after pregnancy, on the growth of their children during the first 2 y of life. We conducted a randomized placebo-controlled trial in 886 mother-infant pairs in Tanzania. At the first prenatal visit, HIV-infected women were randomly assigned to 1 of 4 daily oral regimens in a 2 x 2 factorial fashion: multivitamins (MV: thiamine, riboflavin, vitamin B-6, niacin, vitamin B-12, vitamin C, vitamin E, and folic acid), preformed vitamin A + beta-carotene (VA/BC), MV including VA/BC, or placebo. Supplementation continued during the first 2 y postpartum and thereafter. Children were weighed and measured monthly, and all received vitamin A supplements after 6 mo of age per the standard of care. Multivitamins had a significant positive effect on attained weight (459 g; 95% CI: 35, 882; P = 0.03) and on weight-for-age (0.42; 95% CI: 0.07, 0.77; P = 0.02) and weight-for-length (0.38; 95% CI: 0.07, 0.68; P = 0.01) z scores at 24 mo. VA/BC seemed to reduce the benefits of MV on these outcomes. No significant effects were observed on length, midupper arm circumference, or head circumference. Supplementation of HIV-infected women with multivitamins (vitamin B complex, vitamin C, and vitamin E) during pregnancy and lactation is an effective intervention for improving ponderal growth in children.

To compare sexual problems among HIV-positive and HIV-negative women and describe clinical and psychosocial factors associated with these problems. Data were collected during a study visit of the Women's Interagency HIV Study (WIHS). The WIHS studies the natural and treated history of HIV among women in the United States. Between October 01, 2006, and March 30, 2007, 1805 women (1279 HIV positive and 526 HIV negative) completed a study visit that included administration of the Female Sexual Function Index. In addition, the visit included completion of standardized interviewer-administered surveys, physical and gynecological examinations, and blood sample collection. Women with HIV reported greater sexual problems than did those without HIV. Women also reported lower sexual function if they were classified as menopausal, had symptoms indicative of depression, or if they reported not being in a relationship. CD4 cell count was associated with Female Sexual Function Index scores, such that those with CD4 women's quality of life, greater attention to this issue as a potential component of women's overall HIV care is warranted.

African American women have disproportionately high prevalence rates of HIV and cervical cancer. HIV-infected women are significantly less likely to obtain recommended cervical cancer screenings than HIV-uninfected women. The purpose of this study was to examine sociocultural and structural factors associated with cervical cancer screening among HIV-infected African American in Alabama. The PEN-3 Model and the Health Belief Model were used as theoretical frameworks. In-depth interviews were conducted with twenty HIV-infected African American women to identify perceptions, enablers, and nurturers, perceived susceptibility, perceived severity, and perceived benefits related to cervical cancer and screening. The most common positive perceptions, enablers, and nurturers that contributed to cervical cancer screening included internal motivation and awareness of the importance of HIV-infected women getting Pap tests due to their weakened immune system. Negative perceptions, enablers, and nurturers included lack of knowledge about cervical cancer and screening, and lack of perceived susceptibility to cervical cancer. The results of this study can be used to guide the development of culturally relevant cervical cancer and screening education interventions aimed at increasing cervical cancer screening adherence among HIV-infected African American women.

This study was performed to assess the role of lipopolysaccharide modulators as a marker of microbial translocation among human immunodeficiency virus (HIV)-infected women during pregnancy and to evaluate their association with preterm delivery. The study had a prospective cohort design and was performed at the Hospital Clínic in Barcelona, Spain. Thirty-six pregnant women with and 36 without HIV infection, matched on the basis of age and parity, were included. Maternal blood samples were obtained during the first trimester, during the third trimester, and at delivery. Levels of soluble CD14 (sCD14), human lipopolysaccharide-binding protein (LBP), immunoglobulin M endotoxin core antibodies to lipopolysaccharide (EndoCAb), and interleukin 6 (IL-6) were determined. Fetal cord blood levels of sCD14, LBP, and IL-6 were determined. Results were compared between groups. First trimester sCD14 and LBP levels and third trimester sCD14 levels were significantly higher in the HIV-infected group. HIV-infected women with preterm births and spontaneous preterm births had significantly increased levels of sCD14 throughout pregnancy and significantly increased levels of LBP during the first trimester, compared with HIV-infected women with delivery at term or with HIV-negative women. On multivariate analysis, an independent association was observed between first trimester sCD14 levels and preterm delivery among HIV-infected women. This is the first study to assess inflammatory markers related to microbial translocation during pregnancy among HIV-infected women. Higher levels of sCD14 and LBP were observed in HIV-infected pregnant women and were associated with preterm delivery. © The Author 2015.

We consider an HIV-1 dynamics model by incorporating (i) two routes of infection via, respectively, binding of a virus to a receptor on the surface of a target cell to start genetic reactions (virus-to-target infection), and the direct transmission from infected cells to uninfected cells through the concept of virological synapse in vivo (infected-to-target infection); (ii) two types of distributed-time delays to describe the time between the virus or infected cell contacts an uninfected CD4+ T cell and the emission of new active viruses; (iii) humoral immune response, where the HIV-1 particles are attacked by the antibodies that are produced from the B lymphocytes. The existence and stability of all steady states are completely established by two bifurcation parameters, R 0 (the basic reproduction number) and R 1 (the viral reproduction number at the chronic-infection steady state without humoral immune response). By constructing Lyapunov functionals and using LaSalle's invariance principle, we have proven that, if R 0 ≤ 1 , then the infection-free steady state is globally asymptotically stable, if R 1 ≤ 1 < R 0 , then the chronic-infection steady state without humoral immune response is globally asymptotically stable, and if R 1 > 1 , then the chronic-infection steady state with humoral immune response is globally asymptotically stable. We have performed numerical simulations to confirm our theoretical results.

Background Low maternal vitamin D has been associated with preterm birth (PTB). HIV-infected pregnant women are at risk for PTB, but data on maternal vitamin D and PTB in this population is scarce. Methods In a cohort of Latin American HIV-infected pregnant women from the NICHD International Site Development Initiative (NISDI) protocol, we examined the association between maternal vitamin D status and PTB. Vitamin D status was defined as the following 25-hydroxyvitamin D levels: severe deficiency (<10 ng/mL), deficiency (10-20 ng/mL), insufficiency (21–29 ng/mL), and sufficiency (≥30 ng/mL). PTB was defined as delivery at <37 weeks gestational age (GA). Logistic regression was used to assess the association between maternal vitamin D status and PTB. Results Of 715 HIV-infected pregnant women, 13 (1.8%) were severely vitamin D deficient, 224 (31.3%) deficient, and 233 (32.6%) insufficient. Overall, 23.2% (166/715) of pregnancies resulted in PTB [median GA of PTBs =36 wks (interquartile range: 34-36)]. In multivariate analysis, severe vitamin D deficiency was associated with PTB [Odds Ratio=4.7, 95% Confidence Interval: 1.3-16.8)]. Conclusion Severe maternal vitamin D deficiency is associated with PTB in HIV-infected Latin American pregnant women. Further studies are warranted to determine if vitamin D supplementation in HIV-infected women may impact PTB. PMID:27716863

Gender inequality increases women's risk of hiv infection in Moshi, Tanzania.

This study examined the hypothesis that multiple dimensions of gender inequality increase women's risk for HIV infection using a population-based survey of 1418 women aged 20 to 44 in Moshi, Tanzania. Three forms of HIV exposures were assessed reflecting gender power imbalance: economic exposures (age difference between partners and partner's contributions to children's expenses), physical exposures (coerced first sex and intimate partner violence) and social exposures (ever had problems conceiving). Behavioural risk factors included number of sexual partners for women in the last three years, partner had other wives or girlfriends, non-use of condom and alcohol use at least once a week in the last 12 months. Multivariate logistic regression analysis showed that a woman had a significantly elevated risk for HIV if she had a partner more than 10 years older (OR=2.5), her partner made low financial contributions to children's expenses (OR=1.7), or she experienced coerced first sex before age 18 years (OR=2.0) even after taking into account the effects of risk behaviour factors. The association between ever had problem conceiving and HIV infection was explained away by risk behaviour factors. The findings lend support to the hypothesis that economic deprivation and experience of sexual violence increase women's vulnerability to HIV, providing further evidence for extending the behavioural approach to HIV interventions to incorporate women's economic empowerment, elimination of gender-based violence and promotion of changing attitudes and behaviours among men.

Rapid diagnostic tests (RDTs) are the primary diagnostic tools for HIV used in resource-constrained settings. Without a proper confirmation algorithm, there is concern that false-positive (FP) RDTs could result in misdiagnosis of HIV infection and inappropriate antiretroviral treatment (ART) initiation, but programmatic data on FP are few. We examined the accuracy of RDT diagnosis among HIV-infected pregnant women attending public sector antenatal services in Cape Town, South Africa. We describe the proportion of women found to have started on ART erroneously due to FP RDT results based on pre-ART viral load (VL) testing and enzyme-linked immunosorbent assay (ELISA). We analysed 952 consecutively enrolled pregnant women diagnosed as HIV infected based on two RDTs per local guideline and found 4.5% (43/952) of pre-ART VL results to be <50 copies/ml. After excluding 6 women who had detectable virus on subsequent VL measurements, ELISA was performed on the 37 remaining women. Of these, 3/952 (0.3%) HIV RDT diagnoses were found to be FP. We estimate that using ELISA to confirm all positive RDTs would cost $1110 (uncertainty interval $381-$5382) to identify one patient erroneously initiated on ART, while it costs $3912 for a lifetime of antiretrovirals with VL monitoring for one person. Compared to the cost of confirming the RDT-based diagnoses, the cost of HIV misdiagnosis is high. While testing programmes based on RDT should strive for constant quality improvement, where resources permit, laboratory confirmation algorithms can play an important role in strengthening the quality of HIV diagnosis in the era of universal ART.

To determine if illicit drug use increases the vertical transmission of HIV, to identify the risk factors involved in mother and child health and the prevalence of illicit drug use among these pregnant women. Sixty-four (7.6%) of 845 pregnant women from the metropolitan region of Belo Horizonte, Minas Gerais, Brazil, attended in the service between October 1997 and February 2012 reported the use of illicit drugs. Cases were HIV-positive drug users (n=64) and controls were women who did not use drugs (n=192). Three controls were selected for each case. Several conditions of exposure were considered in the control group such as tobacco use, alcohol use, alcohol and tobacco use, maternal age, educational level, ethnicity, and marital status. Problems during the prenatal period, delivery and postpartum, vertical HIV transmission and neonatal outcomes were also investigated. Univariate analysis showed as significant variables: maternal age, tobacco use, number of prenatal care visits, antiretroviral therapy, mode of infection, and viral load at delivery. Logistic regression revealed as significant variables: maternal age (less than 25 years); tobacco use, and number of prenatal care visits (less than 6). The vertical transmission of HIV was 4,8% (95%CI 1.7-13.3) among drug users and 2,1% (95%CI 0.8-5.2) in the control group, with no statistically significant difference between groups. Neonatal complications were more frequent among drug users, but also with no statistically significant difference between groups. The use of illicit drug is frequent during pregnancy among HIV-infected women. The approach to illicit drug use should be routine during prenatal care visits. These women are more discriminated against and tend to deny their habits or do not seek prenatal care. There was no difference in vertical virus transmission between groups, probably indicating adherence to antiretroviral use for antiretroviral therapies during pregnancy.

The use of population-based survey data together with sound statistical methods can enhance better estimation of HIV risk factors and explain variations across subgroups of the population. The distribution and determinants of HIV infection in populations must be taken into consideration. We analysed data from the HIV Prevalence and Behaviour Survey in Mozambique aiming to find risk factors associated with HIV infection among Mozambican women. The paper provides a complex survey logistic regression model to explain the variation in HIV seropositivity using demographic, socio-economic and behavioural factors. Results show that women aged 25-29 years, living in female-headed households, living in richer households and those widowed, divorced or not living with a partner have higher odds of being HIV-positive. Findings from our study provide a unique and integrated perspective on risk factors for being HIV-positive among Mozambican women and could support the implementation of programmes aiming to reduce HIV infection in Mozambique.

HIV and malaria infections occur in the same individuals, particularly in sub-Saharan Africa. We examined whether daily multivitamin supplementation (vitamins B complex, C, and E) or vitamin A supplementation altered malaria incidence in HIV-infected women of reproductive age. HIV-infected pregnant Tanzanian women recruited into the study were randomly assigned to daily multivitamins (B complex, C, and E), vitamin A alone, both multivitamins and vitamin A, or placebo. Women received malaria prophylaxis during pregnancy and were followed monthly during the prenatal and postpartum periods. Malaria was defined in 2 ways: presumptive diagnosis based on a physician's or nurse's clinical judgment, which in many cases led to laboratory investigations, and periodic examination of blood smears for malaria parasites. Multivitamin supplementation compared with no multivitamins significantly lowered women's risk of presumptively diagnosed clinical malaria (relative risk: 0.78, 95% confidence interval: 0.67 to 0.92), although multivitamins increased their risk of any malaria parasitemia (relative risk: 1.24, 95% confidence interval: 1.02 to 1.50). Vitamin A supplementation did not change malaria incidence during the study. Multivitamin supplements have been previously shown to reduce HIV disease progression among HIV-infected women, and consistent with that, these supplements protected against development of symptomatic malaria. The clinical significance of increased risk of malaria parasitemia among supplemented women deserves further research, however. Preventive measures for malaria are warranted as part of an integrated approach to the care of HIV-infected individuals exposed to malaria.

BACKGROUND HIV infection has been associated with early menopausal onset, which may have adverse long-term health consequences. Antimüllerian hormone, a biomarker of ovarian reserve and gonadal aging, is reduced in HIV-infected women. OBJECTIVE We sought to assess the relationship of antimüllerian hormone to age of menopause onset in HIV-infected women. STUDY DESIGN We used antimüllerian hormone levels measured in plasma in 2461 HIV-infected participants from the Women’s Interagency HIV Study to model the age at final menstrual period. Multivariable normal mixture models for censored data were used to identify factors associated with age at final menstrual period. RESULTS Higher antimüllerian hormone at age 40 years was associated with later age at final menstrual period, even after multivariable adjustment for smoking, CD4 cell count, plasma HIV RNA, hepatitis C infection, and history of clinical AIDS. Each doubling of antimüllerian hormone was associated with a 1.5-year increase in the age at final menstrual period. Median age at final menstrual period ranged from 45 years for those in the 10th percentile of antimüllerian hormone to 52 years for those in the 90th percentile. Other factors independently associated with earlier age at final menstrual period included smoking, hepatitis C infection, higher HIV RNA levels, and history of clinical AIDS. CONCLUSION Antimüllerian hormone is highly predictive of age at final menstrual period in HIV-infected women. Measuring antimüllerian hormone in HIV-infected women may enable clinicians to predict risk of early menopause, and potentially implement individualized treatment plans to prevent menopause-related comorbidities and to aid in interpretation of symptoms.

Objective: To estimate HIV seroprevalence among pregnant women with syphilis and evaluate the influence of syphilis infection on mother-to-child-transmission (MTCT) of HIV by meta-analysis. Methods: We conducted a systematic literature search for 1 678 articles related to maternal syphilis and HIV infection published until October 1 st 2015 using the PubMed, Web of Science, Chinese Web of Knowledge, Wanfang, Weipu, and SinoMed databases and evaluated the quality of each papers using the STROBE checklist, and the keywords were " pregnant women/maternal/pregnancy" , "syphilis/AIDS" , "HIV/human immunodeficiency virus" , "mother- to-child transimission/vertical transmission" . Excluding studies with the special subgroups of HIV-positive pregnant women as the research objects, review or meeting abstract, impossibility of full-text acquisition, sample size <50, duplication or impossibility of data extraction, finally, 16 studies were included. Random-effects meta-analysis was used to estimate HIV seroprevalence among pregnant women with syphilis and the RR of MTCT for women infected with both syphilis and HIV. Subgroup analyses were undertaken by study location, sample size, use of anti-retroviral therapy and study quality. Results: Sixteen studies with a combined sample of 110 573 pregnant women were included in the analysis. Of these, ten reported HIV seroprevalences among pregnant women with syphilis and six studies evaluated the influence of syphilis infection on MTCT of HIV. Pooled estimates yielded a HIV seroprevalence of 11.6% (95 % CI : 6.7%-19.5%) among pregnant women with syphilis. We estimated that the risk of MTCT of HIV was 1.86 times ( RR= 1.86, 95 % CI : 0.89%-3.89%) higher among pregnant women with syphilis compared with those only infected with HIV-although this effect was not statistically significant. Cochran's Q test showed a high degree of heterogeneity in estimates of HIV seroprevalence and the effect of syphilis infection on MTCT of HIV across

Tijuana, Mexico, just south of San Diego, California, is located by the busiest land border crossing in the world. Although UNAIDS considers Mexico to be a country of "low prevalence, high risk," recent surveillance data among sentinel populations in Tijuana suggests HIV prevalence is increasing. The aim of this study was to estimate the number of men and women aged 15 to 49 years infected with HIV in Tijuana. Gender and age-specific estimates of the Tijuana population were obtained from the 2000 Mexican census. Population and HIV prevalence estimates for at-risk groups were obtained from published reports, community based studies, and data from the Centro Nacional para la Prevención y Control del VIH/SIDA (CENSIDA). Age-specific fertility rates for Mexico were used to derive the number of low and high-risk pregnant women. Numbers of HIV-positive men and women were estimated for each at-risk group and then aggregated. A high growth scenario based on current HIV prevalence and a conservative, low growth estimate were determined. A total of 686,600 men and women in Tijuana were aged 15 to 49 years at the time of the 2000 census. Considering both scenarios, the number of infected persons ranged from 1,803 to 5,472 (HIV prevalence: 0.26 to 0.80%). The majority of these persons were men (>70%). The largest number of infected persons were MSM (N = 1,146 to 3,300) and IDUs (N = 147 to 650). Our data suggest that up to one in every 125 persons aged 15-49 years in Tijuana is HIV-infected. Interventions to reduce ongoing spread of HIV are urgently needed.

Uganda has long been successful in controlling the HIV epidemic; however, there is evidence that HIV prevalence and incidence are increasing again. Data on the HIV/STI epidemic among sex workers are so far lacking from Uganda. This paper describes the baseline epidemiology of HIV/STI in a newly established cohort of women involved in high-risk sexual behavior in Kampala, Uganda. Women were recruited from red-light areas in Kampala. Between April 2008 and May 2009, 1027 eligible women were enrolled. Sociodemographic and behavioral information were collected; blood and genital samples were tested for HIV/STI. Risk factors for HIV infection were examined using multivariate logistic regression. HIV seroprevalence was 37%. The prevalence of Neisseria gonorrhoeae was 13%, Chlamydia trachomatis, 9%; Trichomonas vaginalis, 17%; bacterial vaginosis, 56% and candida infection, 11%. Eighty percent had herpes simplex virus 2 antibodies (HSV-2), 21% were TPHA-positive and 10% had active syphilis (RPR+TPHA+). In 3% of the genital ulcers, Treponema pallidum (TP) was identified, Haemophilus ducreyi in 6%, and HSV-2 in 35%. Prevalent HIV was independently associated with older age, being widowed, lack of education, sex work as sole income, street-based sex work, not knowing HIV-status, using alcohol, and intravaginal cleansing with soap. HIV infection was associated with N. gonorrhoeae, T. vaginalis, bacterial vaginosis, HSV-2 seropositivity and active syphilis. Prevalence of HIV/STI is high among women involved in high-risk sexual behavior in Kampala. Targeted HIV prevention interventions including regular STI screening, voluntary HIV testing and counseling, condom promotion, and counseling for reducing alcohol use are urgently needed in this population.

To evaluate if levels of pregnancy-associated plasma protein-A (PAPP-A), free β-hCG and nuchal translucency (NT) used in first trimester aneuploidy screening and α-fetoprotein (AFP), unconjugated oestriol (UE3) and free β-hCG in the second trimester are altered in pregnancies with human immunodeficiency virus (HIV) infection. Median MoM values of biochemical markers and δ-NT in 92 women with HIV infection in the first trimester were compared with those from 912 HIV-seronegative controls. In the second trimester, biochemical marker levels were compared in 52 women with HIV infection and 378 HIV-seronegative controls. First trimester free β-hCG median MoM levels in HIV-infected pregnancies were not different to controls (0.978 vs. 0.981, p = 1.000), as were PAPP-A levels (1.190 vs. 1.102, p = 0.099) and δ-NT (0.1374 vs. 0.0445, p = 0.0631). Second trimester levels of free β-hCG were not significantly different (1.0575 vs. 0.9619, p = 0.1827), as was AFP (0.9734 vs. 0.9350, p = 0.6576), although UE3 was significantly lower (0.970 vs. 1.110, p = 0.0005). In the first trimester, marker levels are not affected by the presence of HIV infection, and risks for aneuploidy are likely to be accurate in this group. Further studies are required to evaluate if UE3 levels continue to be low in HIV-infected women since this may have an impact on screening in the second trimester. Copyright © 2010 S.

Towards an HIV cure based on targeted killing of infected cells: different approaches against acute versus chronic infection.

PubMed

Current regimens of combination antiretroviral therapy (cART) offer effective control of HIV infection, with maintenance of immune health and near-normal life expectancy. What will it take to progress beyond the status quo, whereby infectious virus can be eradicated (a 'sterilizing cure') or fully controlled without the need for ongoing cART (a 'functional cure')? On the basis of therapeutic advances in the cancer field, we propose that targeted cytotoxic therapy to kill HIV-infected cells represents a logical complement to cART for achieving an HIV cure. This concept is based on the fact that cART effectively blocks replication of the virus, but does not eliminate cells that are already infected; targeted cytotoxic therapy would contribute precisely this missing component. We suggest that different modalities are suited for curing primary acute versus established chronic infection. For acute infection, relatively short-acting potent agents such as recombinant immunotoxins might prove sufficient for HIV eradication, whereas for chronic infection, a long-lasting (lifelong?) modality is required to maintain full virus control, as might be achieved with genetically modified autologous T cells. We present perspectives for complementing cART with targeted cytotoxic therapy, whereby HIV infection is either eradicated or fully controlled, thereby eliminating the need for lifelong cART.

Objective To assess the association of HIV infection, HIV disease parameters (including CD4+ T-cell counts, HIV viral load, and AIDS) and antiretroviral medication use with subclinical carotid artery atherosclerosis. Design Cross-sectional study nested within a prospective cohort study Methods Among participants in the Women's Interagency HIV Study (1,331 HIV-infected women, 534 HIV-uninfected women) and Multicenter AIDS Cohort Study (600 HIV-infected men, 325 HIV-uninfected men), we measured subclinical carotid artery lesions and common carotid artery intima-media thickness (CIMT) using B-mode ultrasound. We estimated adjusted mean CIMT differences and prevalence ratios (PRs) for carotid lesions associated with HIV-related disease and treatments, with multivariate adjustment to control for possible confounding variables. Results Among HIV-infected individuals, a low CD4+ T cell count was independently associated with an increased prevalence of carotid lesions. Compared to the reference group of HIV-uninfected individuals, the adjusted PR for lesions among HIV-infected individuals with CD4+ T-cell count <200 cells/mm3 was 2.00 (95% confidence interval 1.22, 3.28) in women and 1.74 (95% confidence interval 1.04, 2.93) in men. No consistent association of antiretroviral medications with carotid atherosclerosis was observed, except for a borderline significant association between protease inhibitor use and carotid lesions in men (with no association among women). History of clinical AIDS and HIV viral load were not significantly associated with carotid atherosclerosis. Conclusions Beyond traditional cardiovascular disease risk factors, low CD4+ T-cell count is the most robust risk factor for increased subclinical carotid atherosclerosis in HIV-infected women and men.

Increasing numbers of pregnant HIV-positive women are receiving combination antiretroviral regimens for preventing mother-to-child virus transmission or for treating the infection itself. Several studies have demonstrated that nucleoside reverse transcriptase inhibitors (NRTIs) induce mitochondrial toxicity by several mechanisms, including depletion of mitochondrial DNA (mtDNA). By the quantification of mtDNA levels, we studied mitochondrial toxicity in HIV-positive women at delivery and the possible correlations with antiretroviral regimens, viroimmunological and metabolic parameters. We analysed 68 HIV-positive women enrolled in the Italian Prospective Cohort Study on Efficacy and Toxicity of Antiretroviral in Pregnancy (TARGET Study); all were taking ≥1 NRTI. We quantified mtDNA copies per cell in subcutaneous fat samples collected during delivery. At the 3rd, 6th and 9th month of pregnancy, we collected data concerning CD4(+) T-cell count, plasma HIV RNA, total and high-density lipoprotein (HDL) cholesterol, fasting plasma glucose and triglycerides. As a control, we analysed mtDNA levels in abdominal subcutaneous fat samples from 23 HIV-seronegative women at delivery. mtDNA content was significantly lower in HIV-infected women when compared with HIV-negative controls. mtDNA content varied independently from viroimmunological, lipid and glucose parameters at the different months, with the exceptions of triglycerides at the 9th month and of HDL at the 6th month of pregnancy. In subcutaneous tissue from women taking NRTI-based antiretroviral regimens, we observed a significant decrease of mtDNA content, compared with uninfected women not on antiviral treatment. Moreover, a significant correlation was noted between mtDNA content and HDL cholesterol and triglycerides.

HIV infected women have higher rates of infertility. Objective. The purpose of this literature review is to evaluate the effectiveness of fresh IVF/ICSI cycles in HIV infected women. A search of the PubMed database was performed to identify studies assessing fresh nondonor oocyte IVF/ICSI cycle outcomes of serodiscordant couples with an HIV infected female partner. Ten studies met the inclusion criteria. Whenever a comparison with a control group was available, with the exception of one case, ovarian stimulation cancelation rate was higher and pregnancy rate (PR) was lower in HIV infected women. However, statistically significant differences in both rates were only seen in one and two studies, respectively. A number of noncontrolled sources of bias for IVF outcome were identified. This fact, added to the small size of samples studied and heterogeneity in study design and methodology, still hampers the performance of a meta-analysis on the issue. Conclusion. Prospective matched case-control studies are necessary for the understanding of the specific effects of HIV infection on ovarian response and ART outcome.

Objective: In the largest cohort study of neuropsychological outcomes among HIV-infected women to date, we examined the association between HIV status and cognition in relation to other determinants of cognitive function (aim 1) and the pattern and magnitude of impairment across cognitive outcomes (aim 2). Methods: From 2009 to 2011, 1,521 (1,019 HIV-infected) participants from the Women's Interagency HIV Study (WIHS) completed a comprehensive neuropsychological test battery. We used multivariable regression on raw test scores for the first aim and normative regression-based analyses (t scores) for the second aim. The design was cross-sectional. Results: The effect sizes for HIV status on cognition were very small, accounting for only 0.05 to 0.09 SD units. The effect of HIV status was smaller than that of years of education, age, race, income, and reading level. In adjusted analyses, HIV-infected women performed worse than uninfected women on verbal learning, delayed recall and recognition, and psychomotor speed and attention. The largest deficit was observed in delayed memory. The association of low reading level with cognition was greater in HIV-infected compared to HIV-uninfected women. HIV biomarkers (CD4 count, history of AIDS-defining illness, viral load) were associated with cognitive dysfunction. Conclusions: The effect of HIV on cognition in women is very small except among women with low reading level or HIV-related comorbidities. Direct comparisons of rates of impairment in well-matched groups of HIV-infected men and women are needed to evaluate possible sex differences in cognition. PMID:25540304

Introduction Combination antiretroviral therapy (cART) can effectively prevent vertical transmission of HIV but there is potential risk of adverse maternal, foetal or infant effects. Specifically, the effect of cART use during pregnancy on mitochondrial DNA (mtDNA) content in HIV-positive (HIV+) women is unclear. We sought to characterize subclinical alterations in peripheral blood mtDNA levels in cART-treated HIV+ women during pregnancy and the postpartum period. Methods This prospective longitudinal observational cohort study enrolled both HIV+ and HIV-negative (HIV-) pregnant women. Clinical data and blood samples were collected at three time points in pregnancy (13-<23 weeks, 23-<30 weeks, 30–40 weeks), and at delivery and six weeks post-partum in HIV+ women. Peripheral blood mtDNA to nuclear DNA (nDNA) ratio was measured by qPCR. Results Over a four year period, 63 HIV+ and 42 HIV- women were enrolled. HIV+ women showed significantly lower mtDNA/nDNA ratios compared to HIV- women during pregnancy (p = 0.003), after controlling for platelet count and repeated measurements using a multivariable mixed-effects model. Ethnicity, gestational age (GA) and substance use were also significantly associated with mtDNA/nDNA ratio (p≤0.02). Among HIV+ women, higher CD4 nadir was associated with higher mtDNA/nDNA ratios (p<0.0001), and these ratio were significantly lower during pregnancy compared to the postpartum period (p<0.0001). Conclusions In the context of this study, it was not possible to distinguish between mtDNA effects related to HIV infection versus cART therapy. Nevertheless, while mtDNA levels were relatively stable over time in both groups during pregnancy, they were significantly lower in HIV+ women compared to HIV- women. Although no immediate clinical impact was observed on maternal or infant health, lower maternal mtDNA levels may exert long-term effects on women and children and remain a concern.

Background. FIB-4 represents a noninvasive, composite index that is a validated measure of hepatic fibrosis, which is an important indicator of liver disease. To date, there are limited data regarding hepatic fibrosis in women. Methods. FIB-4 was evaluated in a cohort of 1227 women, and associations were evaluated in univariate and multivariate regression models among 4 groups of subjects classified by their human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection status. Results. The median FIB-4 scores were 0.60 in HIV-/HCV- women, 0.83 in HIV-/HCV+ women, 0.86 in HIV+/HCV- women, and 1.30 in HIV+/HCV+ women. In the HIV/HCV co-infected group, multivariate analysis showed that CD4+ cell count and albumin level were negatively associated with FIB-4 (P <.0001), whereas antiretroviral therapy (ART) was positively associated with FIB-4 score (P =.0008). For the HIV mono-infected group, multivariate analysis showed that CD4+ cell count (P <.0001) and albumin level (P =.0019) were negatively correlated with FIB-4 score, ART was positively associated with FIB-4 score (P =.0008), and plasma HIV RNA level was marginally associated with FIB-4 score (P =.080). In 72 HIV mono-infected women who were also hepatitis B surface antigen negative, ART naive, and reported no recent alcohol intake, plasma HIV RNA level was associated with increased FIB-4 score (P =.030). Conclusions. HIV RNA level was associated with increased FIB-4 score in the absence of hepatitis B, hepatitis C, ART, or alcohol use, suggesting a potential relationship between HIV infection and hepatic fibrosis in vivo. A better understanding of the various demographic and virologic variables that contribute to hepatic fibrosis may lead to more effective treatment of HIV infection and its co-morbid conditions.

Cervical cancer prevention should be provided as part of primary healthcare services for HIV-infected women but conventional screening programs are difficult to implement in low-resource settings. Here, we evaluate the efficacy among HIV-infected women of a simpler, screen-and-treat strategy in which all women with a positive screening test are treated with cryotherapy. We conducted a randomized clinical trial of two screen-and-treat strategies among 6555 women in Cape Town, South Africa, among whom 956 were HIV-positive. Women were randomized to screen-and-treat utilizing either human papillomavirus DNA testing or visual inspection with acetic acid as the screening method or to a control group. Women were followed for up to 36 months after randomization with colposcopy and biopsy to determine the study endpoint of cervical intraepithelial neoplasia grade 2 or higher. In the control group, HIV-positive women had higher rates of cervical intraepithelial neoplasia grade 2 or higher detected by 36 months (14.9%) than HIV-negative women (4.6%) (P = 0.0006). Screen-and-treat utilizing human papillomavirus DNA testing significantly reduced cervical intraepithelial neoplasia grade 2 or higher through 36 months in both HIV-positive (relative risk = 0.20, 95% confidence interval 0.06-0.69) and HIV-negative women (relative risk = 0.31, 95% confidence interval 0.20-0.50). Reductions in the visual inspection with acetic acid-and-treat group were less marked. Complications of cryotherapy were mostly minor and did not differ in frequency between HIV-positive and HIV-negative women. Screen-and-treat using human papillomavirus testing is a simple and effective method to reduce high-grade cervical cancer precursors in HIV-infected women.

Human papillomaviruses (HPVs) have previously been reported to infect epithelial trophoblast cells of the placenta. To investigate this possibility, 200 placental samples from Zambian women were separated into HIV+ and HIV− groups and tested for HPV by redundant primer PCR, using GP5+/GP6+ and CPI/CPII primer sets. Three HPV genotypes (HPV6, 16 and 90) were detected in placental samples. Whereas, 20 different HPV genotypes were detected in vaginal sampling of the same patients, suggesting that compartment specific sub-populations of HPV may exist. The incidence of HPV16 in placental samples was almost 2-fold greater in HIV+ women compared to HIV− (p = 0.0241). HPV16 L1 expression, detected by immunochemistry, was significantly higher in HIV+ than HIV− samples (p = 0.0231). HPV16 DNA was detected in the nuclei of trophoblast cells by in situ hybridization. Overall, these results suggest that HPVs infect the placenta and that HIV significantly influences these infections. PMID:26865986

The gender inequalities that characterise intimate partner relationships in Malawi, a country with one of the highest HIV prevalence rates in the world, arguably place marriage as an important risk factor for HIV infection among women, yet few studies detail the complex interactions of marriage and risk. In order to develop HIV-prevention interventions that have lasting impacts in such communities, we need a deeper understanding of the intricacies of women's lives, how and why they are involved in marital relationships, and the implications of these relationships for HIV transmission or prevention. This article describes how women understand marriage's effects on their lives and their HIV risks. Drawing from focus group discussions with 72 women attending antiretroviral clinics in Malawi, we explore why women enter marriage, what women's experiences are within marriage and how they leave spouses for other relationships. Based on their narratives, we describe women's lives after separation, abandonment or widowhood, and report their reflections on marriage after being married two or three times. We then review women's narratives in light of published work on HIV, and provide recommendations that would minimise the risks of HIV attendant on marriage.

This study reported the effect of gender difference on HIV seropositive late testers or advanced infection. A retrospective cohort study of newly diagnosed HIV seropositive based on adatabase in the main referral hospital in Denpasar, Bali, Indonesia from 2004 – 2016. Women and man were categorized as late testers (CD4 ≤ 200 cells/uL and/or AIDS diagnosis ≤ 12 months from first HIV test date). Non-late testers (CD4 > 200 cells/uL and/or no AIDS diagnosis during study period or diagnosis of AIDS >12 months from HIV diagnosis), of reproductive age (13 – 49 years old), and not of reproductive age (>49 years old). Logistic regression was used to estimate risk and its statistical significance. The model consists of gender and age correctly classified 83.5% of cases. Women were almost two times more likely to present as non-late testers compared to men, and reproductive age of 15 – 49 years were 1.5 times more likely to present as non-late testers compared to those with age > 49 years. Women affected by HIV almost in equal as for men. Women and those within reproductive age were more likely to present before the advanced stage compared to men and those aged > 49 years.

BACKGROUND: Concurrent infection with HIV and human papillomavirus (HPV) in women is associated with increased rates of cervical dysplasia and shorter survival following the development of cervical cancer. The authors examined risk factors for HPV infection at study entry in HIV-positive women enrolled in the Canadian Women's HIV Study, a prospective open cohort study. METHODS: Subjects eligible for this analysis included the 375 HIV-positive women in the Canadian Women's HIV Study for whom HPV test results were available. Questionnaires on behavioural and clinical information, Pap smears, cervicovaginal lavage specimens and vaginal tampon specimens for HPV detection and typing by polymerase chain reaction were obtained at study entry. RESULTS: Overall, 67.2% (252/375) of the women were HPV-positive; the global prevalence of intermediate- and high-risk oncogenic HPV types was 49.1% (184/375). Women with squamous cell dysplasia (32/294) were more likely to have HPV infection than those without dysplasia (90.6% v. 62.6%; p = 0.002). Multivariate logistic regression analysis, with adjustment for number of lifetime partners and history of STD, revealed that the following risk factors were independently associated with HPV infection: CD4 count of less than 0.20 x 10(9)/L (adjusted odds ratio [OR] 1.99 [95% confidence interval (Cl) 1.17-3.37 (p = 0.011)]), non-white race (adjusted OR 2.00 [95% Cl 1.17-3.42 (p = 0.011)]), inconsistent condom use in the 6 months before study entry (adjusted OR 2.02 [95% Cl 1.16-3.50 (p = 0.013)]), and lower age, with women age 30-39 years (adjusted OR 0.51 [95% Cl 0.30-0.87 (p = 0.013)]) and age 40 years or older (adjusted OR 0.52 [95% Cl 0.26-1.01 (p = 0.052)]) compared with women less than 30 years of age. INTERPRETATION: Close monitoring for HPV-related effects is warranted in all HIV-positive women, particularly younger, non-white women who do not always use condoms.

Objectives Antiretroviral (ARV) therapy has prolonged the life expectancy of HIV-infected persons, increasing their risk of age-associated diseases including atherosclerosis (AS). Decreased risk of AS has been associated with the prevention and control of hypertension (HTN). We conducted a cohort study of perimenopausal women and older men with or at-risk of HIV infection to identify risk factors for incident HTN. Methods Standardized interviews, physical examinations, and laboratory examinations were scheduled at 6-month intervals. Interview data included demographics, medical, family, sexual behavior, and drug use histories, and physical activity. Results There were 330 women and 329 men eligible persons; 27% and 35% of participants developed HTN during a median follow-up of 1080 and 1071 days, respectively. In gender-stratified analysis, adjusting for traditional HTN risk factors (age, race, BMI, smoking, diabetes, family history of HTN, alcohol dependence, physical activity, and high cholesterol), HIV infection was not associated with incident HTN in women or men [HR= 1.31, 95%CI (0.56, 3.06); HR = 1.67, 95%CI (0.75, 3.74), respectively]. Among HIV-infected women, although exposure to ARV's was not significantly associated with incident HTN [HR=0.72, 95%CI (0.26, 1.99)], CD4+ T-cell count was positively associated with incident HTN [HR=1.15 per 100 cells, 95%CI (1.03, 1.28)]. Among physically active HIV-infected men, exposure to ARV's was negatively associated with incident HTN [HR=0.15, 95%CI (0.03, 0.78)]. Conclusions HIV infection was not associated with incident HTN in older men or women. This study provides additional evidence supporting a causal relationship between immune function and incident HTN, which warrants further study. PMID:23294666

During an HIV-1 prevention clinical trial in East Africa, we observed 16 cases of primary HIV-1 infection in women coincident with pregnancy or breastfeeding. Nine of eleven pregnant women initiated rapid combination antiretroviral therapy (ART), despite having CD4 counts exceeding national criteria for ART initiation; breastfeeding women initiated ART or replacement feeding. Rapid ART initiation during primary HIV-1 infection during pregnancy and breastfeeding is feasible in this setting.

In HIV-infected pregnant women, viral suppression prevents mother-to-child HIV transmission. Directly observed highly-active antiretroviral therapy (HAART) enhances virological suppression, and could prevent transmission. Our objective was to project the effectiveness and cost-effectiveness of directly observed administration of antiretroviral drugs in pregnancy. A mathematical model was created to simulate cohorts of one million asymptomatic HIV-infected pregnant women on HAART, with women randomly assigned self-administered or directly observed antiretroviral therapy (DOT), or no HAART, in a series of Monte Carlo simulations. Our primary outcome was the quality-adjusted life expectancy in years (QALY) of infants born to HIV-infected women, with the rates of Caesarean section and HIV-transmission after DOT use as intermediate outcomes. Both self-administered HAART and DOT were associated with decreased costs and increased life-expectancy relative to no HAART. The use of DOT was associated with a relative risk of HIV transmission of 0.39 relative to conventional HAART; was highly cost-effective in the cohort as a whole (cost-utility ratio $14,233 per QALY); and was cost-saving in women whose viral loads on self-administered HAART would have exceeded 1000 copies/ml. Results were stable in wide-ranging sensitivity analyses, with directly observed therapy cost-saving or highly cost-effective in almost all cases. Based on the best available data, programs that optimize adherence to HAART through direct observation in pregnancy have the potential to diminish mother-to-child HIV transmission in a highly cost-effective manner. Targeted use of DOT in pregnant women with high viral loads, who could otherwise receive self-administered HAART would be a cost-saving intervention. These projections should be tested with randomized clinical trials.

Malaria is a leading cause of morbidity and mortality among HIV-infected pregnant women in sub-Saharan Africa: at least 1 million pregnancies among HIV-infected women are complicated by co-infection with malaria annually, leading to increased risk of premature delivery, severe anaemia, delivery of low birth weight infants, and maternal death. Current guidelines recommend either daily cotrimoxazole (CTX) or intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-SP) for HIV-infected pregnant women to prevent malaria and its complications. The cost-effectiveness of CTX compared to IPTp-SP among HIV-infected pregnant women was assessed. A microsimulation model of malaria and HIV among pregnant women in five malaria-endemic countries in sub-Saharan Africa was constructed. Four strategies were compared: (1) 2-dose IPTp-SP at current IPTp-SP coverage of the country ("2-IPT Low"); (2) 3-dose IPTp-SP at current coverage ("3-IPT Low"); (3) 3-dose IPTp-SP at the same coverage as antiretroviral therapy (ART) in the country ("3-IPT High"); and (4) daily CTX at ART coverage. Outcomes measured include maternal malaria, anaemia, low birth weight (LBW), and disability-adjusted life years (DALYs). Sensitivity analyses assessed the effect of adherence to CTX. Compared with the 2-IPT Low Strategy, women receiving CTX had 22.5% fewer LBW infants (95% CI 22.3-22.7), 13.5% fewer anaemia cases (95% CI 13.4-13.5), and 13.6% fewer maternal malaria cases (95% CI 13.6-13.7). In all simulated countries, CTX was the preferred strategy, with incremental cost-effectiveness ratios ranging from cost-saving to $3.9 per DALY averted from a societal perspective. CTX was less effective than the 3-IPT High Strategy when more than 18% of women stopped taking CTX during the pregnancy. In malarious regions of sub-Saharan Africa, daily CTX for HIV-infected pregnant women regardless of CD4 cell count is cost-effective compared with 3-dose IPTp-SP as long as more than 82% of women adhere to

To measure the incidence rates of preterm delivery in HIV-infected pregnant women and to explore related potential risk factors. Data from 'Information System of Prevention of Mother-to-child Transmission of HIV Management in China, 2013' was used in the study. Information regarding demographic characteristics, pregnancy, HIV relevant situations and pregnancy outcomes related to these HIV-infected pregnant women, were extracted and analyzed. Incidence of preterm delivery was calculated with related potential risk factors explored. 3 913 HIV-infected pregnant women were involved in this study, including 336 of them having undergone preterm deliveries (8.6%). Results from univariate and multivariate analyses showed that preterm delivery was associated with factors as: maternal age, ethnicity, education, being migrant, pregnancy hypertension, multiple pregnancy and times of antenatal care visits (P < 0.05) of the pregnant women. Compared with those who contracted the HIV infection through drug injection, the ones who were infected through other routes suffered fewer preterm deliveries (adjusted OR = 0.562, 95% CI: 0.360-0.879). Pregnant women who received antiretroviral therapy either between 14 to 27 gestational weeks or during the period of less than 14, were more likely to experience preterm delivery, comparison to those who did not receive the therapy during pregnancy. The adjusted ORs were 1.712 (95% CI: 1.196-2.451) and 1.862 (95% CI: 1.261-2.749), respectively. Preterm delivery was a common adverse outcome during pregnancy among HIV-infected women in China. Other than traditionally known risk factors, routes of transmission and the use of antiretroviral therapy might also be associated with the increased risks for preterm delivery.

Intimate partner violence (IPV) during pregnancy may be common in settings where HIV is prevalent but there are few data on IPV in populations of HIV-infected pregnant women in Southern Africa. We examined the prevalence and correlates of IPV among HIV-infected pregnant women. A primary care antenatal clinic in Cape Town, South Africa. 623 consecutive HIV-infected pregnant women initiating lifelong antiretroviral therapy. IPV, depression, substance use and psychological distress were assessed using the 13-item WHO Violence Against Women questionnaire, the Edinburgh Postnatal Depression Scale (EPDS), Alcohol and Drug Use Disorders Identification Tests (AUDIT/DUDIT) and the Kessler 10 (K-10) scale, respectively. The median age in the sample was 28 years, 97% of women reported being in a relationship, and 70% of women reported not discussing and/or agreeing on pregnancy intentions before conception. 21% of women (n=132) reported experiencing ≥1 act of IPV in the past 12 months, including emotional (15%), physical (15%) and sexual violence (2%). Of those reporting any IPV (n=132), 48% reported experiencing 2 or more types. Emotional and physical violence was most prevalent among women aged 18-24 years, while sexual violence was most commonly reported among women aged 25-29 years. Reported IPV was less likely among married women, and women who experienced IPV were more likely to score above threshold for substance use, depression and psychological distress. In addition, women who reported not discussing and/or not agreeing on pregnancy intentions with their partner prior to conception were significantly more likely to experience violence. HIV-infected pregnant women in the study reported experiencing multiple forms of IPV. While the impact of IPV on maternal and child health outcomes in the context of HIV infection requires further research attention, IPV screening and support services should be considered within the package of routine care for HIV-infected

Anemia is a frequent complication among HIV-infected persons and is associated with faster disease progression and mortality. We examined the effect of multivitamin supplementation on hemoglobin concentrations and the risk of anemia among HIV-infected pregnant women and their children. HIV-1-infected pregnant women (n = 1078) from Dar es Salaam, Tanzania, were enrolled in a double-blind trial and provided daily supplements of preformed vitamin A and beta-carotene, multivitamins (vitamins B, C, and E), preformed vitamin A and beta-carotene + multivitamins, or placebo. All women received iron and folate supplements only during pregnancy according to local standard of care. The median follow-up time for hemoglobin measurement for mothers was 57.3 mo [interquartile range (IQR): 28.6-66.8] and for children it was 28.0 mo (IQR: 5.3-41.7). During the whole period, hemoglobin concentrations among women who received multivitamins were 0.33 g/dL higher than among women who did not receive multivitamins (P=0.07). Compared with placebo, multivitamin supplementation resulted in a hemoglobin increase of 0.59 g/dL during the first 2 y after enrollment (P=0.0002). Compared with placebo, the children born to mothers who received multivitamins had a reduced risk of anemia. In this group, the risk of macrocytic anemia was 63% lower than in the placebo group (relative risk: 0.37: 95% CI: 0.18, 0.79; P=0.01). Multivitamin supplementation provided during pregnancy and in the postpartum period resulted in significant improvements in hematologic status among HIV-infected women and their children, which provides further support for the value of multivitamin supplementation in HIV-infected adults.

Preeclampsia and HIV/AIDS are inflammatory conditions that contribute significantly to adverse maternal and foetal outcomes. The immune reconstitution effects of HAART on inflammatory mediators has not been adequately studied in pregnancy and may impact on the inflammatory cytokine network in women with co-morbid preeclampsia. Our study evaluated changes in pro-inflammatory cytokines IL-2, TNF-α, IFN-γ and IL-6 in HIV infected preeclamptic women on HAART. A prospective experimental study was conducted at Prince Mshiyeni Memorial Hospital between July 2013 and September 2014. One hundred and ninety three pregnant women were recruited into 4 groups: uninfected normotensive (50; 26%), infected normotensive (45; 23%), uninfected preeclamptic (53; 28%) and infected preeclamptic women (45; 23%). Serum levels of cytokines TNF-α, IFN- γ, IL-2 and IL-6 were determined using commercially available kits and a Cytometric Bead Array (CBA). Comparative data was recorded and analysed descriptively. In the control groups (normotensive), significantly lower values were found in IL-2 (p = 0.010), TNF-α (p = 0.045), and IL-6 (p = 0.005); and a non-significant decrease was observed in IFN-γ (p = 0.345) in HIV infected women on HAART compared to uninfected controls. In the experimental group (preeclamptic) women, significantly reduced levels were observed in IL-2 and TNF-α (p = 0.001; p = 0.000) and non-significant decreases were observed in IFN-γ and IL-6 (p = 0.023; p = 0.086) in HIV infected women on HAART compared with uninfected preeclamptic women. Non-significant differences were observed between uninfected preeclamptic and normotensive women. In uncomplicated/normotensive pregnancies, HIV/HAART is associated with significant decreases in IL-2, TNF-α and IL-6, and in preeclamptic women significant decreases in IL-2 and TNF-α were observed. These findings suggest that HIV/HAART impacts on pro-inflammatory cytokines in women with co-morbid preeclampsia. This provides a

HIV reservoirs and production of viral antigens are not eliminated in chronically infected participants treated with combination antiretroviral therapy (cART). Novel therapeutic strategies aiming at viral reservoir elimination are needed to address chronic immune dysfunction and non-AIDS morbidities that exist despite effective cART. The HIV envelope protein (Env) is emerging as a highly specific viral target for therapeutic elimination of the persistent HIV-infected reservoirs via antibody-mediated cell killing. Dual-Affinity Re-Targeting (DART) molecules exhibit a distinct mechanism of action via binding the cell surface target antigen and simultaneously engaging CD3 on cytotoxic T lymphocytes (CTLs). We designed and evaluated Env-specific DARTs (HIVxCD3 DARTs) derived from known antibodies recognizing diverse Env epitopes with or without broadly neutralizing activity. HIVxCD3 DARTs derived from PGT121, PGT145, A32, and 7B2, but not VRC01 or 10E8 antibodies, mediated potent CTL-dependent killing of quiescent primary CD4 T cells infected with diverse HIV isolates. Similar killing activity was also observed with DARTs structurally modified for in vivo half-life extension. In an ex vivo model using cells isolated from HIV-infected participants on cART, combinations of the most potent HIVxCD3 DARTs reduced HIV expression both in quiescent and activated peripheral blood mononuclear cell cultures isolated from HIV-infected participants on suppressive cART. Importantly, HIVxCD3 DARTs did not induce cell-to-cell virus spread in resting or activated CD4 T cell cultures. Collectively, these results provide support for further development of HIVxCD3 DARTs as a promising therapeutic strategy for targeting HIV reservoirs. PMID:26539983

In Mozambique, women are the most affected by HIV/AIDS. Self-efficacy is one of the main predictors of effective use of a condom. Therefore, it is essential to identify the factors that influence condom-use negotiation self-efficacy in vulnerable women. The aim of this paper is to identify socio-demographic, marital, and psychosocial factors associated with condom-use negotiation self-efficacy among Mozambican women at risk for HIV infection. Participants were women (173) who were patients at the Gynecology Department of the Central Hospital of Beira, Mozambique, and at risk for HIV infection. Women completed measures of condom-use negotiation self-efficacy, HIV prevention knowledge, and perceived barriers against safer sex. The results showed that demographic and marital variables are associated with condom-use negotiation self-efficacy, namely, those having more than 9 years of education, who are younger and not living with a partner, and who talk about AIDS with partners report higher condom-use negotiation self-efficacy. Regarding psychosocial factors, higher HIV prevention knowledge and fewer perceived barriers to safer sex predict higher condom-use negotiation self-efficacy. These results can contribute to sexual health promotion and HIV/AIDS prevention in Mozambican women because they identify at-risk groups and marital and psychosocial malleable factors that can be targeted in AIDS prevention among at-risk Mozambican women.

Prevalence and risk factors for isolated antibody to hepatitis B core antigen (anti-HBc) and occult hepatitis B virus (HBV) infection are not well known in human immunodeficiency virus type 1 (HIV-1)-infected pregnant women. It is unclear if women with occult infections are at risk of transmitting HBV to their infants. HIV-1-infected and HBV surface antigen (HBsAg)-negative pregnant women were tested for antibody to HBsAg (anti-HBs) and anti-HBc using enzyme immunoassay. Women with isolated anti-HBc were assessed for occult HBV infection, defined as HBV DNA levels >15 IU/mL, using the Abbott RealTime HBV DNA assay. Infants born to women with isolated anti-HBc and detectable HBV DNA were tested at 4 months of age for HBV DNA. Logistic regression analysis was used to identify factors associated with isolated anti-HBc and occult HBV infection. Among 1812 HIV-infected pregnant women, 1682 were HBsAg negative. Fourteen percent (95% confidence interval [CI], 12%-15%) of HBsAg-negative women had an isolated anti-HBc that was independently associated with low CD4 count, age >35 years, birth in northern Thailand, and positive anti-hepatitis C virus serology. Occult HBV infection was identified in 24% (95% CI, 18%-30%) of women with isolated anti-HBc, representing 2.6% (95% CI, 1.9%-3.5%) of HIV-1-infected pregnant women, and was inversely associated with HIV RNA levels. None of the women with isolated anti-HBc and occult HBV infection transmitted HBV to their infants. HIV-1-infected pregnant women with isolated anti-HBc and occult HBV infection have very low HBV DNA levels and are thus at very low risk to transmit HBV to their infants.

In this retrospective case-control study, we analyse data of 48 HIV-positive pregnant patients, versus a control group of 99 HIV-negative pregnant women, followed as outpatients by our department from 2009 to 2014. The aims of the study were to investigate the prevalence, persistence and progression of cervical squamous intraepithelial lesions (SIL) in each group and to correlate colpo-cytological lesions to the socio-demographic and clinical-laboratory findings in the HIV + pregnant women. In our study we observed that immunosuppression, HPV infection and vaginal coinfections were predictive of cervical lesions. Pap smear and colposcopy should be part of routine care for HIV-infected pregnant women because these lesions behave aggressively in these patients. Success of prevention depends on massive access of patients to screening. HAART reduces viral load and maintains CD4 count and can affect progression of SIL. Multidisciplinary services on the same site appear to be one promising strategy to improve compliance in patients. Impact Statement What is already known on this subject: Our study provided novel information on a highly vulnerable population of young HIV + pregnant women. What the results of this study add: We observed that immunosuppression, HPV infection and vaginal coinfections were predictive of cervical lesions remarkable with colposcopy. We could consider these important risk factors to evaluate to establish an appropriate strategy of management for these patients. What the implications are of these findings for clinical practice and/or further research: Association of the risk between SIL presence and HIV and HPV infection also deserves additional investigation. We believe that Pap smears and colposcopies should be part of the routine care for HIV-infected women because these lesions behave particularly aggressively in these patients.

Breastfeeding is a cost-effective, yet underutilized strategy to promote maternal and infant health in low and middle income countries (LMICs). Breastfeeding remains challenging for mothers living with HIV in LMICs, yet few studies have examined mental health predictors of breastfeeding initiation and continuation. We investigated breastfeeding among mothers by HIV status in South Africa, evaluating predictors of breastfeeding initiation and continuation to identify intervention-targets. Breastfeeding patterns were investigated in a subsample of 899 breastfeeding mothers from the Drakenstein Child Health Study; a prospective birth cohort of 1225 pregnant women, between March 2012 and March 2015 in a peri-urban area. Breastfeeding was assessed at 5 time-points between 6weeks and 24months' infant age. Cox proportional hazard models evaluated breastfeeding initiation and duration. Logistic regression models with breastfeeding non-initiation as the outcome parameter were performed to determine associations with maternal sociodemographic, psychosocial factors and gestational outcomes. More HIV-uninfected mothers initiated breastfeeding (n=685, 97%) than HIV-infected mothers (n=87, 45%). Median duration of exclusive breastfeeding was short (2months), but HIV-infected mothers engaged in exclusive breastfeeding for longer duration than uninfected mothers (3 vs 2months). Despite concerning high rates, mental disorders were not significant predictors of breastfeeding behaviour. Employment and HIV diagnosis during pregnancy predicted a lower likelihood of breastfeeding initiation among HIV-infected mothers, while employment was associated with earlier breastfeeding-discontinuation in HIV-uninfected mothers. Findings indicate that future interventions should target sub-populations such as HIV-infected women because of distinct needs. Workplace interventions appear particularly key for mothers in our study. Copyright © 2017 Elsevier Inc. All rights reserved.

Toxoplasmosis is a disease caused by a protozoal parasite: Toxoplasma gondii . This infection can cause severe illness when the organism is contracted congenitally or when it is reactivated in immunosuppressed people. In this paper we review for the first time prevalence and risk factors of T. gondii among pregnant women and HIV-infected adults in Morocco. A systematic review methodology was used to consult three databases: Pub Med, Science Direct and Google Scholar dated until 2015, regarding prevalence data and risk factors of infection among pregnant women and people living with HIV. Data collection and eligibility criteria were established in this paper. No statistical method was employed in this study. Our review resulted in a total of 6 publications meeting the inclusion criteria of prevalence and risk factors of toxoplasmosis in Morocco. Seropositive rates of T. gondii infection reach up to 51% in pregnant women. Risk factors that were reported included contact with soil, lack of knowledge about toxoplasmosis, and a low educational level. For HIV-infected adults, the limited data show a 62.1% prevalence rate of T. gondii .According to our review, there is still very little information on toxoplasmosis disease in pregnant women and HIV infected patients in Morocco. Further research on toxoplasmosis is needed to better ascertain the human disease burden in Morocco.

We assessed changes in self-reported sexual activity (SA) over 13 years among HIV-infected and uninfected women. The impact of aging and menopause on SA and unprotected anal or vaginal intercourse (UAVI) was examined among women in the Women’s Interagency HIV Study (WIHS), stratifying by HIV status and detectable viral load among HIV-infected women. Generalized mixed linear models were fitted for each outcome, adjusted for relevant covariates. HIV-uninfected women evidenced higher levels of SA and UAVI than HIV-infected. The odds of SA declined by 62–64 % per decade of age. The odds of SA in a 6-month interval for women aged 40–57 declined by 18–22 % post-menopause (controlling for age). Among HIV+/detectable women only, the odds of any UAVI decreased by 17 % per decade of age; the odds of UAVI were unchanged pre-menopause, and then decreased by 28 % post-menopause. Elucidating the factors accounting for ongoing unprotected sex among older women should inform interventions. PMID:25245474

Purpose HIV-infected pregnant women in sub-Saharan Africa are at risk for depression and alcohol abuse. Young women may be more vulnerable, but little is known about the psychosocial functioning of this population. Methods We compared younger (18–24 year-olds) and older (≥25 year-olds) HIV-infected pregnant women initiating antiretroviral therapy (ART) in Cape Town, South Africa. Women were assessed on a range of psychosocial measures, including the Alcohol Use Disorders Identification Test, and the Edinburgh Postnatal Depression Scale (EPDS). Results Among 625 women initiating ART, 16% reported risky alcohol use, and 21% alcohol-related harm; these percentages were similar across age groups. When younger women were stratified by age, 37% of 18–21 year-olds vs. 20% of 22–24 year-olds reported alcohol-related harm (p=0.02). Overall, 11% of women had EPDS scores suggesting probable depression, and 6% reported self-harming thoughts. Younger women reported more depressive symptoms. Report of self-harming thoughts was 11% in younger and 4% in older women (p=0.003). In multivariable analysis, age remained significantly associated with depressive symptoms and report of self-harming thoughts. Level of HIV-related stigma and report of intimate partner violence modified the association between age and depressive symptoms. Conclusions Young HIV-infected pregnant women in South Africa were more likely to report depressive symptoms and self-harming thoughts compared to older women and the youngest women reported the highest levels of alcohol-related harm. HIV-related stigma may be a moderating factor. These findings have implications for maternal and infant health, underscoring the urgent need for effective targeted interventions in this vulnerable population. PMID:27815628

Lights and Shadows about the Effectiveness of IVF in HIV Infected Women: A Systematic Review

Background. HIV infected women have higher rates of infertility. Objective. The purpose of this literature review is to evaluate the effectiveness of fresh IVF/ICSI cycles in HIV infected women. Materials and Methods. A search of the PubMed database was performed to identify studies assessing fresh nondonor oocyte IVF/ICSI cycle outcomes of serodiscordant couples with an HIV infected female partner. Results and Discussion. Ten studies met the inclusion criteria. Whenever a comparison with a control group was available, with the exception of one case, ovarian stimulation cancelation rate was higher and pregnancy rate (PR) was lower in HIV infected women. However, statistically significant differences in both rates were only seen in one and two studies, respectively. A number of noncontrolled sources of bias for IVF outcome were identified. This fact, added to the small size of samples studied and heterogeneity in study design and methodology, still hampers the performance of a meta-analysis on the issue. Conclusion. Prospective matched case-control studies are necessary for the understanding of the specific effects of HIV infection on ovarian response and ART outcome. PMID:26778910

Women of reproductive age account for nearly half of all HIV-infected people worldwide. Childbearing intention among HIV-infected women is complicated by social and reproductive concerns related to their HIV status. We conducted a cross-sectional study of HIV-infected and HIV-uninfected sexually active South African women aged 17 to 21 in order to compare their childbearing intentions and to identify predictors of the desire to have children among women with HIV. We found the rate of childbearing intention to be similarly high among both HIV-infected and HIV-uninfected study participants (80 and 79% respectively, p=0.81). History of previous parity was found to be associated with decreased intention to have children. No difference in childbearing intention was found between HIV-infected women on anti-retroviral therapy (ART) and women not on ART. High rates of childbearing intention among HIV-infected women require integration of reproductive health services with comprehensive HIV/AIDS care in order to mitigate the risks of sexual and vertical transmission of HIV.

To describe pregnancy outcomes among HIV-infected women and examine factors associated with live birth among those receiving and not receiving combination antiretroviral therapy (cART). The present analysis included women with HIV from Uganda and Zimbabwe who participated in a prospective cohort study during 2001-2009. Incident pregnancies and pregnancy outcomes were recorded quarterly. The Kaplan-Meier method was used to estimate incident pregnancy probabilities; factors associated with live birth were evaluated by Poisson regression with generalized estimating equations. Among 306 HIV-infected women, there were 160 incident pregnancies (10.1 per 100 women-years). The pregnancy rate was higher among cART-naïve women than among those receiving cART (10.7 vs 5.5 per 100 women-years; P=0.047), and it was higher in Uganda than in Zimbabwe (14.4 vs 7.7 per 100 women-years; P<0.001). Significant associations were noted between a live birth and prenatal care (relative risk 3.9; 95% confidence interval 2.2-6.9) and illness during pregnancy (relative risk 0.8; 95% confidence interval 0.7-1.0). Women not receiving cART have higher pregnancy rates than do those receiving cART, but cART use might not affect the risk of adverse pregnancy outcomes. Timely prenatal care and monitoring of illnesses during pregnancy should be incorporated into treatment services for HIV-infected women.

Objective. To compare HIV drug resistance in pregnant women with perinatal HIV (PHIV) and those with nonperinatal HIV (NPHIV) infection. Methods. We conducted a multisite cohort study of PHIV and NPHIV women from 2000 to 2014. Sample size was calculated to identify a fourfold increase in antiretroviral (ARV) drug resistance in PHIV women. Continuous variables were compared using Student's t-test and Wilcoxon rank-sum tests. Categorical variables were compared using χ (2) and Fisher's exact tests. Univariate analysis was used to determine factors associated with antiretroviral drug resistance. Results. Forty-one PHIV and 41 NPHIV participants were included. Women with PHIV were more likely to have drug resistance than those with NPHIV ((55% versus 17%, p = 0.03), OR 6.0 (95% CI 1.0-34.8), p = 0.05), including multiclass resistance (15% versus 0, p = 0.03), and they were more likely to receive nonstandard ARVs during pregnancy (27% versus 5%, p = 0.01). PHIV and NPHIV women had similar rates of preterm birth (11% versus 28%, p = 0.08) and cesarean delivery (47% versus 46%, p = 0.9). Two infants born to a single NPHIV woman acquired HIV infection. Conclusions. PHIV women have a high frequency of HIV drug resistance mutations, leading to nonstandard ARVs use during pregnancy. Despite nonstandard ARV use during pregnancy, PHIV women did not experience increased rates of adverse pregnancy outcomes.

Despite a resilient spirit, the challenges that face low-income, aging Black women living with HIV infection are immense. This article describes a 10-year iterative history of using the Theory of Silencing the Self (TSTS) as an explanatory model that was found to be gender sensitive, culturally relevant, and helpful in guiding a community-based participatory research group of low-income, HIV-infected Black women living in Boston, Massachusetts. The group, called Sistah Powah, used the TSTS to design and implement a structured writing intervention in a women's drop-in center targeting low-income, aging Black women living with HIV infection as a way to give them and others a voice.

Women with HIV who want to have children face a range of challenges, quandaries, and hard decisions. This article examines the role of health staff in supporting HIV-infected pregnant women who desire to maintain their pregnancies. The article is derived from anthropological research conducted in Vietnam's Quang Ninh Province, an area that has a high HIV prevalence rate and is covered under the government's prevention of mother-to-child transmission program. The study included in-depth interviews with 23 HIV-infected women who had either recently given birth or were pregnant at the time of the research. Results showed that women were satisfied with the services they received from the program. The women believed that health care staff offered them not only medical care but also social and emotional support. The article concludes that the health care system is a vital point of support for pregnant women with HIV.

Introduction Young adolescent women in sub-Saharan Africa are three to four times more likely to be HIV-positive than boys or men. One of the relationship dynamics that is likely to be associated with young women's increased vulnerability to HIV is transactional sex. There are a range of HIV-related risk behaviours that may drive this vulnerability. However, to date, limited epidemiological data exist on the role of transactional sex in increasing HIV acquisition, especially among young women in sub-Saharan Africa. Our paper presents data on the prevalence of self-reported engagement in transactional sex and explores whether transactional sex is associated with increased risk of HIV infection among a cohort of young, rural, sexually active South African women. We also explore whether this relationship is mediated through certain HIV-related risk behaviours. Methods We analyzed baseline data from a phase III trial of conditional cash transfers for HIV prevention of 693 sexually active, school-going young women aged 13–20 years in rural South Africa. We examined the association between young women's engagement in transactional sex and HIV infection. Transactional sex is defined as a non-commercial, non-marital sexual relationship whereby sex is exchanged for money and/or gifts. We explored whether this relationship is mediated by certain HIV-related risk behaviours. We used logistic and multinomial regression and report unadjusted and adjusted odds ratios with 95% CI. Results Overall, 14% (n=97) of sexually active young women reported engaging in transactional sex. Engagement in transactional sex was associated with an increased risk of being HIV-positive (aOR: 2.5, CI: 95% 1.19–5.25, p=0.01). The effect size of this association remained nearly unchanged when adjusted for certain other dimensions of HIV risk that might help explain the underlying pathways for this relationship.

To assess the burden of maternal malaria and HIV among pregnant women in Ghana and to determine the risk of anemia among women with dual infection. A cross-sectional study was conducted at 4 hospitals in the Sekondi-Takoradi metropolis, Ghana. The study group comprised 872 consenting pregnant women attending prenatal care clinics. Venous blood samples were screened for malaria, HIV, and hemoglobin level. Multivariate logistic regression analysis was performed to determine the association between malaria, HIV, and risk of anemia. In all, 34.4% of the study cohort had anemia. Multivariate logistic regression analysis indicated that pregnant women with either malaria (odds ratio 1.99; 95% confidence interval, 1.43-2.77; P=<0.001) or HIV (odds ratio 1.78; 95% confidence interval, 1.13-2.80; P=0.014) had an increased risk of anemia. In adjusted models, pregnant women co-infected with both malaria and HIV displayed twice the risk of anemia. The adjusted odds ratio was 2.67 (95% confidence interval, 1.44-4.97; P=0.002). Pregnant women infected with both malaria and HIV are twice as likely to be anemic than women with a single infection or no infection. Measures to control malaria, HIV, and anemia during pregnancy are imperative to improve birth outcomes in this region of Ghana. Copyright © 2012 International Federation of Gynecology and Obstetrics.

Objective To explore the gut-brain axis by examining gut hormone levels and cognitive test scores in women with (HIV+) and without (HIV−) HIV infection. Design/methods Participants included 356 women (248 HIV+, 108 at risk HIV−) in the Brooklyn Women’s Interagency HIV Study (WIHS) with measured levels of ghrelin, amylin and gastric inhibitory peptide (GIP), also known as glucose-dependent insulinotropic polypeptide. Cross-sectional analyses using linear regression models estimated the relationship between gut hormones and Trails A, Trails B, Stroop interference time, Stroop word recall, Stroop color naming and reading, and Symbol Digit Modalities Test (SDMT) with consideration for age, HIV infection status, Wide Range Achievement Test score (WRAT), CD4 count, insulin resistance, drug use, and race/ethnicity. Results Among women at mid-life with chronic (at least 10 years) HIV infection or among those at risk, ghrelin, amylin and GIP were differentially related to cognitive test performance by cognitive domain. Better performance on cognitive tests was generally associated with higher ghrelin, amylin and GIP levels. However, the strength of association varied, as did significance level by HIV status. Conclusion Previous analyses in WIHS participants have suggested that higher BMI, waist, and WHR are associated with better cognitive function among women at mid-life with HIV infection. This study indicates that higher gut hormone levels are also associated with better cognition. Gut hormones may provide additional mechanistic insights regarding the association between obesity and Type 2 diabetes and cognition in middle-aged HIV+ and at risk HIV− women. In addition, measuring these hormones longitudinally would add to the understanding of mechanisms of actions of these hormones and their use as potential clinical tools for early identification and intervention on cognitive decline in this vulnerable population.

Summary We evaluated vitamin D status in HIV+ and HIV− postmenopausal African-American (AA) and Hispanic women. Most women (74–78%) had insufficient 25-hydroxyvitamin D (25OHD) levels, regardless of HIV status. 25OHD was lower in AA women and women lacking supplement use, providing support for screening and supplementation. Among HIV+ women, 25OHD was associated with current CD4 but not type of antiretroviral therapy. Introduction To evaluate vitamin D status and factors associated with vitamin D deficiency and insufficiency in HIV-infected (HIV+) postmenopausal minority women. Methods In this cross-sectional study, 89 HIV+ and 95 HIV− postmenopausal women (33% AA and 67% Hispanic) underwent assessment of 25OHD, 1,25-dihydroxyvitamin D, parathyroid hormone, markers of bone turnover and bone mineral density by dual energy X-ray absorptiometry. Results The prevalence of low 25OHD did not differ by HIV status; the majority of both HIV+ and HIV− women (74–78%) had insufficient levels (<30 ng/ml). Regardless of HIV status, 25OHD was significantly lower in AA subjects, and higher in subjects who used both calcium and multi-vitamins. In HIV+ women on antiretroviral therapy (ART), 25OHD was directly associated with current CD4 count (r= 0.32; p<0.01) independent of age, ethnicity, BMI, or history of AIDS-defining illness. No association was observed between 1,25(OH)2D and CD4 count or between serum 25OHD, 1,25(OH)2D or PTH and type of ART. Conclusions In postmenopausal minority women, vitamin D deficiency was highly prevalent and associated with AA race and lack of supplement use, as well as lower current CD4 cell count. These results provide support for screening and repletion of vitamin D in HIV+ patients. PMID:20585939

This study describes the prevalence of abuse and mental health issues among a cohort of HIV-infected Haitian women living in the United States. We present data on 96 women, ages 19-73 years (M = 47.6, SD = 11.1), who were screened for mental health concerns between 2009 and 2012. Results demonstrated that 12.5% of the women reported a history of abuse. However, posttraumatic stress disorder (PTSD) secondary to HIV was reported by approximately 34% of women. Depression and anxiety were also highly reported, with rates of 49% and 43%, respectively. Women who reported a history of abuse were more likely to report anxiety, PTSD, and PTSD related to HIV symptoms than those without. Our findings suggest that Haitian HIV-infected women may underreport abuse and experience significant depression and anxiety. These preliminary results could be used to develop future studies and to design and implement culturally sensitive interventions for this underserved population.

Preventing HIV in U.S. women and girls: a call for social action.

PubMed

Gómez, Cynthia A

2011-11-01

Successes in HIV prevention efforts in the U.S. have resulted in drastic reductions in the number of new infections in the U.S. among white gay men and injection drug users, a stabilization in overall annual rates of new HIV infections, and near eradication of mother-to child transmission of HIV. Despite this remarkable progress, the proportion of AIDS cases in women has slowly, quietly, and steadily increased from 7% in 1985 to 25% in 2008. The fact the prevention efforts have not reduced HIV spread among women suggests that targeting the individual behaviors of women to prevent HIV acquisition is not a sufficiently effective public health strategy. Interventions that more broadly address the needs of women and their families, and address the contextual factors in which HIV risk occurs are more likely to lead to measurable and sustainable progress. Over the past 30 years, we have seen the U.S. HIV epidemic in women become similar to patterns of HIV risk among women in the developing world. In 2009, 85% of women who acquired HIV became infected through sex with a man and the majority (83%) of them were non-white women. Efforts to understand these immense disparities and create gender-responsive strategies must be a priority within our National HIV/AIDS Strategy. Copyright © 2011 Jacobs Institute of Women's Health.

As with many infectious diseases throughout history, stigma is a part of the trajectory of the HIV disease process. HIV-related stigma impedes women from being tested for HIV. Once infected, HIV-related stigma hinders women from disclosing their HIV status to sexual partners and health care providers, engaging in medical care, effectively self-managing the disease after infection, and adhering to anti-retroviral therapy. After three decades of the HIV epidemic, no evidenced-based, culturally relevant, gender-specific interventions exist to help women infected with HIV manage the stigma associated with HIV infection. This manuscript reports the feasibility of using an iPod touch device and acceptability of a stigma reduction intervention with HIV-infected women in the Deep South in a mixed-method, randomized clinical trial. Results from the study demonstrate that it is feasible to utilize an iPod touch device to deliver an HIV-related stigma intervention to women. Further, women report that the HIV-related stigma intervention is acceptable and meaningful.

Background Women in South Africa are at particularly high-risk for HIV infection and are dependent on their male partners' use of condoms for sexual risk reduction. However, many women are afraid to discuss condoms with male partners, placing them at higher risk of HIV infection. Purpose To examine the association between fear of condom negotiation with HIV testing and transmission risk behaviors, including alcohol use and sexual risks among South African women. Method Women (N = 1333) residing in a primarily Xhosa-speaking African township in Cape Town and attending informal alcohol-serving venues (shebeens) completed anonymous surveys. Logistic regression was used to test the hypothesis that fear of condom negotiation would be associated with increased risk for HIV. Results Compared to women who did not fear condom negotiation, those who did were significantly less likely to have been tested for HIV, were more likely to have experienced relationship abuse, and to report more alcohol use and more unprotected sex. Conclusions For women in South Africa, fear of condom negotiation is related to higher risk of HIV. HIV prevention efforts, including targeted HIV counseling and testing, must directly address gender issues. PMID:23056211

HIV-infected pregnant women in sub-Saharan Africa are at risk for depression and alcohol abuse. Young women may be more vulnerable, but little is known about the psychosocial functioning of this population. We compared younger (18-24 years old) and older (≥25 years old) HIV-infected pregnant women initiating antiretroviral therapy (ART) in Cape Town, South Africa. Women were assessed on a range of psychosocial measures, including the Alcohol Use Disorders Identification Test and the Edinburgh Postnatal Depression Scale (EPDS). Among 625 women initiating ART, 16 % reported risky alcohol use and 21 % alcohol-related harm; these percentages were similar across age groups. When younger women were stratified by age, 37 % of 18-21 years old versus 20 % of 22-24 years old reported alcohol-related harm (p = 0.02). Overall, 11 % of women had EPDS scores suggesting probable depression, and 6 % reported self-harming thoughts. Younger women reported more depressive symptoms. Report of self-harming thoughts was 11 % in younger and 4 % in older women (p = 0.002). In multivariable analysis, age remained significantly associated with depressive symptoms and report of self-harming thoughts. Level of HIV-related stigma and report of intimate partner violence modified the association between age and depressive symptoms. Young HIV-infected pregnant women in South Africa were more likely to report depressive symptoms and self-harming thoughts compared to older women, and the youngest women reported the highest levels of alcohol-related harm. HIV-related stigma and intimate partner violence may be moderating factors. These findings have implications for maternal and infant health, underscoring the urgent need for effective targeted interventions in this vulnerable population.

Neighborhood characteristics shape sexual risk in HIV-uninfected adults in the United States (US). We assess relationships between census tract characteristics and sexual risk behaviors in a predominantly HIV-infected cohort of women living in the Southern US. This cross-sectional multilevel analysis included data from 737 HIV-infected and HIV-uninfected women enrolled in the Women's Interagency HIV Study. Administrative data captured characteristics of census tracts where women lived; participant-level data were gathered via survey. We used principal components analysis to condense tract-level variables into components: social disorder (e.g., violent crime rate), and social disadvantage (e.g., alcohol outlet density). We used hierarchical generalized linear models to assess relationships between tract-level characteristics and condomless vaginal intercourse, anal intercourse, and condomless anal intercourse. Greater social disorder was associated with less anal intercourse (OR = 0.63, 95% CI = 0.43-0.94) and condomless anal intercourse (OR = 0.49, 95% CI = 0.30-0.80), regardless of HIV status. There were no statistically significant additive or multiplicative interactions between tract characteristics and HIV status. Neighborhood characteristics are associated with sexual risk behaviors among women living in the Southern US, these relationships do not vary by HIV status. Future studies should establish temporality and explore the causal pathways through which neighborhoods influence sexual risk. Copyright © 2017 Elsevier Inc. All rights reserved.

Tuberculosis (TB) is the worldwide leading cause of death among HIV-infected individuals, accounting for more than half of AIDS-related deaths. A high risk of tuberculosis (TB) has been shown in early stages of the HIV disease, even in the presence of normal CD4+ cell counts. Moreover, the factors that determine protective immunity vs. susceptibility to M. tuberculosis cannot be fully explained by simple changes in IFNγ levels or a shift from Th1 to Th2 cytokines. This work investigated the relationship between cytokine expression profiles in peripheral blood mononuclear cells (PBMC) and susceptibility to M. tuberculosis in ten HIV+ women who went on to develop TB. RNA transcripts for IL-4, IL-4δ2, IL-10, IL-12(p35), IL-13, IL-17A, IFNγ and TNFα were measured by real-time quantitative PCR in unstimulated or TB peptide antigen-stimulated PBMCs from ten HIV+ women with positive tuberculin skin tests (TST) and compared with HIV-seropositive and seronegative women without previous TB and negative TST. Stimulated PBMC cultures showed significantly lower expression of IL-12p35 (p=0.004) and IL-10 (p=0.026) in the HIV+TB+ group six to twelve months before onset of TB compared to HIV+TB− women. Unstimulated PBMC from HIV+TB+ women also had lower expression of Th2 cytokines [IL-4 (p=0.056) and IL-13 (p=0.050)] compared to HIV+TB− women. These results suggest that lower IL-12 production by PBMC in response to TB antigens and lower levels of both Th1 and Th2 cytokines by PBMC correlate with future development of TB in HIV-infected women and may be responsible for their increased susceptibility.

By the year 2000 there will be six million pregnant women and five to ten million children infected with HIV-1. Intervention strategies have been planned and in some instances already started. A timely and cost-effective strategy needs to take into account that most HIV-1 infected individuals reside in developing countries. Further studies are needed on immunological and virological factors affecting HIV-1 transmission from mother to child, on differential disease progression in affected children, and on transient infection.

Low prevalence of renal dysfunction in HIV-infected pregnant women: implications for guidelines for the prevention of mother-to-child transmission of HIV.

Emerging international guidelines for the prevention of mother-to-child transmission of HIV infection across sub-Saharan Africa call for the initiation of a triple-drug antiretroviral regimen containing tenofovir, a potentially nephrotoxic agent, in all HIV-infected pregnant women at the first antenatal clinic visit. While there are significant benefits to the rapid initiation of antiretroviral therapy (ART) in pregnancy, there are few data on the prevalence of pre-existing renal disease in HIV-infected pregnant women and in turn, the potential risks of this approach are not well understood. We analysed data on renal function in consecutive patients eligible for ART at a large primary healthcare clinic in Cape Town. All individuals were screened for renal dysfunction via serum creatinine and estimation of creatinine clearance via the Cockroft-Gault equation. Over a 2-year period, 238 pregnant women, 1014 non-pregnant women and 609 men were screened to initiate ART. Pregnant women eligible were significantly younger, in earlier stages of HIV disease, had higher CD4 cell counts and lower HIV viral loads, than non-pregnant adults. The median serum creatinine in pregnant women (46 µmol/L) was significantly lower and the median creatinine clearance (163 ml/min/1.73 m(2) ) was significantly higher than other groups (P < 0.001 and P = 0.004, respectively). Fewer than 1% of pregnant women had moderate renal dysfunction before ART initiation, with no instances of severe dysfunction observed, compared to 7% moderate or severe renal dysfunction in non-pregnant women or men (P < 0.001). Renal dysfunction in HIV-infected pregnant women is significantly less common than in other HIV-infected adults eligible for ART. The risks associated with initiating tenofovir immediately in pregnant women before reviewing serum creatinine results may be limited, and the benefits of rapid ART initiation in pregnancy may outweigh possible risks of nephrotoxicity. © 2013 John Wiley & Sons Ltd.

Biomedical Approaches to HIV Prevention in Women.

PubMed

Heumann, Christine L

2018-04-17

Effective HIV prevention techniques for women are of critical importance, as nearly half of all HIV infections globally are in women. This article reviews the recent literature on biomedical approaches to HIV prevention in women. In trials in which women were adherent to oral pre-exposure prophylaxis (PrEP), PrEP was equally efficacious in men and women. However, in studies of oral PrEP exclusively in women, adherence was low, and it was not efficacious. In trials of topical PrEP, including vaginal tenofovir gel and the monthly dapivirine ring, efficacy was also dependent upon adherence. Treatment as prevention (TasP) is a very effective HIV prevention strategy, though limited in that it is not controlled by the HIV-uninfected partner. Adherence is an important factor in the efficacy of biomedical interventions for HIV prevention in women; continued research is needed to identify the most efficacious and acceptable agents for women. Oral PrEP is currently recommended for the following groups of HIV-negative women: heterosexual women in ongoing sexual relationships with a partner infected with or at substantial risk of HIV infection and women who inject drugs and share injection or drug preparation equipment.

Cervical cancer is strongly linked to high-risk human papillomavirus (HR-HPV) and is typically preceded by cytological abnormalities. Less is known in patients with normal cervical cytology (NCC). We investigated the epidemiology of HR-HPV among HIV-infected women with NCC. We conducted a cross-sectional study between January and June 2011 among HIV-infected women with NCC at an adult HIV clinic in Jos, Nigeria. Cervical sampling and analysis for HR-HPV by hybrid capture (HC2) with signal amplification was done to determine presence of one or more of the following HR-HPV types: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 or 68. Epidemiologic factors associated with HR-HPV were determined using bivariate statistics and multivariate logistic regression. We evaluated 103 HIV-infected women with Pap cytology. The median age of the women was 32 years (range 21-49). Ninety-seven (94.2%) had NCC. Cervical samples for HR-HPV DNA testing were available from 89/97 (91.8%) of the HIV-infected women with NCC. Of the 89 women with cervical samples for HR-HPV DNA testing, 40 (44.9%) had detectable HR-HPV by HC2 giving a HR-HPV prevalence of 44.9% (95% CI 33.9-55.5%). Age < 30 years was associated with HR-HPV (OR 2.69 [95% CI 1.05-6.91, p = 0.039]) while history of previous abortion showed an inverse association with HR-HPV (OR 0.33[95% CI 0.15-0.94, p = 0.039]). The prevalence of HR-HPV is seemingly high among HIV-infected women with NCC in our clinical setting. These data provide support for further investigation of the clinical implications of positive HR-HPV among HIV-infected women with NCC report in cervical cancer prevention programs in Nigeria.

This study examined the experiences and perceived benefits of support group participation among HIV-infected women in South Africa. From a qualitative analysis of responses, key psychological processes through which support groups are potentially beneficial were identified. These processes included: identification; modeling; acceptance; and empowerment. The participants' consequent life changes were explored in order to associate these processes with the positive outcomes of support group participation. Through understanding the relationship between the psychological processes within a support group setting and the potential benefits, and by targeting these processes in the development and implementation of future support group interventions, a framework is provided for achieving positive outcomes associated with support group participation.

Objective Current guidelines call for HIV-infected women to deliver via scheduled Caesarean when the maternal HIV viral load (VL) is >1,000 copies/ml. We describe the mode of delivery among HIV-infected women and evaluate adherence to relevant recommendations. Study Design We performed a population-based surveillance analysis of HIV-infected pregnant women in Philadelphia from 2005 to 2013, comparing mode of delivery (vaginal, scheduled Caesarean, or emergent Caesarean) by VL during pregnancy, closest to the time of delivery (≤1,000 copies/ml versus an unknown VL or VL >1,000 copies/ml) and associated factors in multivariable analysis. Results Our cohort included 824 deliveries from 648 HIV-infected women, of whom 69.4% had a VL ≤1,000 copies/ml and 30.6% lacked a VL or had a VL >1,000 copies/ml during pregnancy, closest to the time of delivery. Mode of delivery varied by VL: 56.6% of births were vaginal, 30.1% scheduled Caesarean, and 13.3% emergent Caesarean when the VL was ≤1,000 copies/ml; when the VL was unknown or >1,000 copies/ml, 32.9% of births were vaginal, 49.9% scheduled Caesarean and 17.5% emergent Caesarean. In multivariable analyses, Hispanic women (adjusted odds ratio (AOR) 0.17, 95% Confidence Interval (CI) 0.04–0.76) and non-Hispanic black women (AOR 0.27, 95% CI 0.10–0.77) were less to likely to deliver via scheduled Caesarean compared to non-Hispanic white women. Women who delivered prior to 38 weeks’ gestation (AOR 0.37, 95% CI 0.18–0.76) were also less likely to deliver via scheduled Caesarean compared to women who delivered after 38 weeks’ gestation. An interaction term for race and gestational age at delivery was significant in multivariable analysis. Non-Hispanic black (AOR 0.06, 95% CI 0.01–0.36) and Hispanic women (AOR 0.03, 95% CI 0.00–0.59) were more likely to deliver prematurely and less likely to deliver via scheduled C-section compared to non-Hispanic white women.

Chlamydia trachomatis infection is one of the most prevalent bacterial STIs in the USA and worldwide, and women with C. trachomatis infection are at increased risk of acquiring HIV. Because immune activation at the genital mucosa facilitates HIV/SIV infection, C. trachomatis-mediated cytokine induction may contribute to increased HIV transmission in asymptomatic women. To begin to elucidate the mechanisms, we longitudinally analyzed profiles of innate immune factors and HIV infectivity in genital secretions from anatomically specific sites in asymptomatic women during C. trachomatis infection and post-antibiotic treatment. We found higher levels of cytokines and chemokines in endocervical secretions than vaginal secretions. Compared with the convalescent state, G-CSF, IL-1α, and RANTES were elevated in endocervical secretions, IFN-γ and TNF-α were elevated in vaginal secretions, and IFNγ, IL-1β, and MIP1-α were elevated in cervicolavage fluid (CVL), before adjustment of multiple comparisons. Elevated endocervical levels of IP-10 and MCP-1 were associated with the use of hormonal contraception in infected women after successful treatment, suggesting the role of hormonal contraception in inflammation independent of STIs. Importantly, soluble factors found in endocervical secretions during infection enhanced HIV infectivity while no difference in HIV infectivity was found with vaginal secretions or CVL during infection or at convalescence. Taken together, the profiles of immune mediators and in vitro HIV infectivity indicate that the endocervical and vaginal mucosa are immunologically distinct. Our results underscore the importance of considering anatomical site and local sampling methodology when measuring mucosal responses, particularly in the presence of C. trachomatis infection.

Although there is widespread interest in understanding how models of care for delivering antiretroviral therapy (ART) may influence patient outcomes, family-focused approaches have received little attention. In particular, there have been few investigations of whether the co-enrollment of HIV-infected family members may improve adult ART outcomes over time. We examined the association between co-enrollment of HIV-infected family members into care and outcomes of women initiating ART in 12 HIV care and treatment programs across sub-Saharan Africa. Using data from the mother-to-child transmission-(MTCT) Plus Initiative, women starting ART were categorized according to the co-enrollment of an HIV-infected partner and/or HIV-infected child within the same program. Mortality and loss to follow-up were assessed for up to 5 years after women's ART initiation. Of the 2877 women initiating ART included in the analysis, 31% (n = 880) had at least 1 HIV-infected family member enrolled into care at the same program, including 24% (n = 689) who had an HIV-infected male partner, and 10% (n = 295) who had an HIV-infected child co-enrolled. There was no significant difference in the risk of death of women by family co-enrollment status (P = 0.286). However, the risk of loss to follow-up was greatest among women who did not have an HIV-infected family member co-enrolled (19% after 36 months on ART) compared with women who had an HIV-infected family member co-enrolled (3%-8% after 36 months on ART) (P < 0.001). These associations persisted after adjustment for demographic and clinical covariates and were consistent across countries and care programs. These data provide novel evidence for the association between adult outcomes on ART and co-enrollment of HIV-infected family members into care at the same program. Interventions that build on women's family contexts warrant further consideration in both research and policies to promote retention in ART services across sub-Saharan Africa.

In 2016, an estimated 1.5 million females aged 15-24 years were living with human immunodeficiency virus (HIV) infection in Eastern and Southern Africa, where the prevalence of HIV infection among adolescent girls and young women (3.4%) is more than double that for males in the same age range (1.6%) (1). Progress was assessed toward the Joint United Nations Programme on HIV/AIDS (UNAIDS) 2020 targets for adolescent girls and young women in sub-Saharan Africa (90% of those with HIV infection aware of their status, 90% of HIV-infected persons aware of their status on antiretroviral treatment [ART], and 90% of those on treatment virally suppressed [HIV viral load <1,000 HIV RNA copies/mL]) (2) using data from recent Population-based HIV Impact Assessment (PHIA) surveys in seven countries. The national prevalence of HIV infection in adolescent girls and young women aged 15-24 years, the percentage who were aware of their status, and among those persons who were aware, the percentage who had achieved viral suppression were calculated. The target for viral suppression among all persons with HIV infection is 73% (the product of 90% x 90% x 90%). Among all seven countries, the prevalence of HIV infection among adolescent girls and young women was 3.6%; among those in this group, 46.3% reported being aware of their HIV-positive status, and 45.0% were virally suppressed. Sustained efforts by national HIV and public health programs to diagnose HIV infection in adolescent girls and young women as early as possible to ensure rapid initiation of ART should help achieve epidemic control among adolescent girls and young women.

Background. Pregnant women infected with human immunodeficiency virus (HIV) may have particular vulnerability to 2009 pandemic H1N1 influenza (pH1N1) infection. The safety and immunogenicity of pH1N1 vaccination in HIV-infected pregnant women are unknown. Methods. HIV-infected women 18–39 years of age and 14–34 weeks’ gestation on antiretroviral therapy received two 30-μg doses of unadjuvanted, inactivated pH1N1 vaccine 21 days apart. Hemagglutination inhibition titers were measured at entry, 21 days after dose 1, and 10 and 21 days after dose 2, and, in mothers and infants, at delivery and 3 and 6 months postdelivery. Results. No severe vaccine-related adverse events were observed among 127 subjects. At entry, 21% had seroprotective (≥1:40) titers. Seroprotection and seroresponse (≥4-fold rise) occurred in 73% and 66% after dose 1 and 80% and 72% after dose 2, respectively. Of women lacking seroprotection at entry, 66% attained seroprotection after dose 1 and 75% after dose 2. Seroprotective titers were present in 67% of mothers and 65% of infants at delivery (median 66 days after dose 2), 60% of mothers and 26% of infants at 3 months postdelivery, and 59% of mothers and 12% of infants at 6 months postdelivery. Conclusions. Two 30-μg doses were moderately immunogenic in HIV-infected pregnant women. No concerning vaccine-related safety signals were observed. Seroprotection persisted in most women postpartum. Efficient transplacental antibody transfer occurred, but seroprotection in infants waned rapidly. Vaccination to protect HIV-infected pregnant women and their newborns from new influenza strains is feasible, but more immunogenic platforms should be evaluated.

Objective: Although our understanding of viral transmission among people who inject drugs (PWID) has improved, we still know little about when and how many times each injector transmits HIV throughout the duration of infection. We describe HIV dynamics in PWID to evaluate which preventive strategies can be efficient. Design: Due to the notably scarce interventions, HIV-1 spread explosively in Russia and Ukraine in 1990s. By studying this epidemic between 1995 and 2005, we characterized naturally occurring transmission dynamics of HIV among PWID. Method: We combined publicly available HIV pol and env sequences with prevalence estimates from Russia and Ukraine under an evolutionary epidemiology framework to characterize HIV transmissibility between PWID. We then constructed compartmental models to simulate HIV spread among PWID. Results: In the absence of interventions, each injector transmits on average to 10 others. Half of the transmissions take place within 1 month after primary infection, suggesting that the epidemic will expand even after blocking all the post–first month transmissions. Primary prevention can realistically target the first month of infection, and we show that it is very efficient to control the spread of HIV-1 in PWID. Treating acutely infected on top of primary prevention is notably effective. Conclusion: As a large proportion of transmissions among PWID occur within 1 month after infection, reducing and delaying transmissions through scale-up of harm reduction programmes should always form the backbone of HIV control strategies in PWID. Growing PWID populations in the developing world, where primary prevention is scarce, constitutes a public health time bomb. PMID:27824626

Enhancement of HIV-specific immunity is likely required to eliminate latent HIV infection. Here, we have developed an immunotherapeutic modality aimed to improve T cell–mediated clearance of HIV-1–infected cells. Specifically, we employed Dual-Affinity Re-Targeting (DART) proteins, which are bispecific, antibody-based molecules that can bind 2 distinct cell-surface molecules simultaneously. We designed DARTs with a monovalent HIV-1 envelope-binding (Env-binding) arm that was derived from broadly binding, antibody-dependent cellular cytotoxicity–mediating antibodies known to bind to HIV-infected target cells coupled to a monovalent CD3 binding arm designed to engage cytolytic effector T cells (referred to as HIVxCD3 DARTs). Thus, these DARTs redirected polyclonal T cells to specifically engage with and kill Env-expressing cells, including CD4+ T cells infected with different HIV-1 subtypes, thereby obviating the requirement for HIV-specific immunity. Using lymphocytes from patients on suppressive antiretroviral therapy (ART), we demonstrated that DARTs mediate CD8+ T cell clearance of CD4+ T cells that are superinfected with the HIV-1 strain JR-CSF or infected with autologous reservoir viruses isolated from HIV-infected–patient resting CD4+ T cells. Moreover, DARTs mediated CD8+ T cell clearance of HIV from resting CD4+ T cell cultures following induction of latent virus expression. Combined with HIV latency reversing agents, HIVxCD3 DARTs have the potential to be effective immunotherapeutic agents to clear latent HIV-1 reservoirs in HIV-infected individuals. PMID:26413868

Objectives We examined parameters of sexual partnerships, including respondents’ participation in concurrency, belief that their partner had concurrent partnerships (partners’ concurrency), and partnership intervals, among the 2,099 women in HIV Prevention Trials Network 064, a study of women at high risk for HIV infection, in ten US communities. Methods We analyzed baseline survey responses about partnership dates to determine prevalence of participants’ and partners’ concurrency, intervals between partnerships, knowledge of whether recent partner(s) had undergone HIV testing, and intercourse frequency during the preceding 6 months. Results Prevalence of participants’ and partners’ concurrency was 40% and 36% respectively; 24% of respondents had both concurrent partnerships and non-monogamous partners. Among women with >1 partner and no concurrent partnerships themselves, the median gap between partners was one month. Multiple episodes of unprotected vaginal intercourse with >2 of their most recent partners was reported by 60% of women who had both concurrent partnerships and non-monogamous partners, 50% with only concurrent partners and no partners’ concurrency, and 33% with only partners’ concurrency versus 14% of women with neither type of concurrency (p<.0001). Women who had any involvement with concurrency were also more likely than women with no concurrency involvement to report lack of awareness of whether recent partners had undergone HIV testing (participants’ concurrency 41%, partners’ concurrency 40%, both participants’ and partners’ concurrency 48%, neither 17%; p<.0001). Conclusions These network patterns and short gaps between partnerships may create substantial opportunities for HIV transmission in this sample of women at high risk for HIV infection. PMID:24056163

Sex trafficking of girls and women is widespread across South Asia and is recognized as both a violent gender-based crime and major human rights violation. Inadequate empirical data exist to characterize this phenomenon and its related health consequences, such as human immunodeficiency virus (HIV) infection. To determine the prevalence of HIV infection among repatriated sex-trafficked Nepalese girls and women and to identify trafficking-related predictors of such infection. Medical and case records of 287 repatriated girls and women reporting being trafficked from Nepal for sexual exploitation and receiving rehabilitative services between January 1997 and December 2005 at a major nongovernmental organization were systematically reviewed in January 2006. Major Nepalese nongovernmental organization providing shelter and care to repatriated survivors of sex trafficking. Prevalence of and risk for HIV based on demographic characteristics and on trafficking- and prostitution-related experiences. Among 287 repatriated Nepalese sex-trafficked girls and women, 109 (38.0%) tested positive for HIV. Among those with complete documentation of trafficking experiences (n = 225), median age at time of trafficking was 17.0 years, with 33 (14.7%) trafficked prior to age 15 years. Compared with those trafficked at 18 years or older, girls trafficked prior to age 15 years were at increased risk for HIV (adjusted odds ratio [AOR], 3.70; 95% confidence interval [CI], 1.32-10.34), with 20 of 33 (60.6%) infected among this youngest age group. Additional factors associated with HIV positivity included being trafficked to Mumbai (AOR, 4.85; 95% CI, 2.16-10.89) and longer duration of forced prostitution (AOR, 1.02; 95% CI, 1.01-1.03; indicating increased risk per additional month of brothel servitude). In post hoc analyses, girls trafficked prior to age 15 years had increased odds of having been detained in multiple brothels (odds ratio [OR], 5.03; 95% CI, 1.96-12.93) and in brothels for a

Abstract Depression affects up to 30% of human immunodeficiency virus (HIV)-infected individuals. We estimated joint effects of antiretroviral therapy (ART) initiation and depressive symptoms on time to death using a joint marginal structural model and data from a cohort of HIV-infected women from the Women's Interagency HIV Study (conducted in the United States) from 1998–2011. Among 848 women contributing 6,721 years of follow-up, 194 participants died during follow-up, resulting in a crude mortality rate of 2.9 per 100 women-years. Cumulative mortality curves indicated greatest mortality for women who reported depressive symptoms and had not initiated ART. The hazard ratio for depressive symptoms was 3.38 (95% confidence interval (CI): 2.15, 5.33) and for ART was 0.47 (95% CI: 0.31, 0.70). Using a reference category of women without depressive symptoms who had initiated ART, the hazard ratio for women with depressive symptoms who had initiated ART was 3.60 (95% CI: 2.02, 6.43). For women without depressive symptoms who had not started ART, the hazard ratio was 2.36 (95% CI: 1.16, 4.81). Among women reporting depressive symptoms who had not started ART, the hazard ratio was 7.47 (95% CI: 3.91, 14.3). We found a protective effect of ART initiation on mortality, as well as a harmful effect of depressive symptoms, in a cohort of HIV-infected women. PMID:28430844

The transgender community represents an understudied population in the literature. The objective of this study was to compare risk behavior, and HIV and sexually transmitted infection (STI) rates between transgender women and transgender men undergoing community-based HIV testing.With this retrospective analysis of a cohort study, we characterize HIV infection rates as well as reported risk behaviors and reported STI in 151 individual transgender women and 30 individual transgender men undergoing community based, voluntary screening for acute and early HIV infection (AEH) in San Diego, California between April 2008 and July 2014.HIV positivity rate was low for both, transgender women and transgender men undergoing AEH screening (2% and 3%, respectively), and the self-reported STI rate for the prior 12 months was 13% for both. Although transgender women appeared to engage in higher rates of risk behavior overall, with 69% engaged in condomless receptive anal intercourse (CRAI) and 11% engaged in sex work, it is important to note that 91% of transgender women reported recent sexual intercourse, 73% had more than 1 sexual partner, 63% reported intercourse with males, 37% intercourse with males and females, and 30% had CRAI.Our results indicate that in some settings rates of HIV infection, as well as rates of reported STIs and sexual risk behavior in transgender men may resemble those found in transgender women. Our findings support the need for comprehensive HIV prevention in both, transgender women and men.

Little is known about the type-specific prevalence of anal human papillomavirus (HPV) infection and risk factors for anal high-risk (HR) HPV infection in human immunodeficiency virus (HIV)-infected women. A cross-sectional study of anal and cervical HPV infection was nested within a gynecological cohort of HIV-infected women. Specimens were tested for type-specific DNA using a polymerase chain reaction-based assay. The study population consisted of 311 women with a median age of 45.3 years, of whom 42.8% originated from sub-Saharan Africa and 96.8% were receiving combination antiretroviral therapy. The median CD4(+)cell count was 612/μL, and the HIV load was <50 copies/mL in 84.1%. HR-HPV types were detected in the anal canal in 148 women (47.6%) and in the cervix in 82 (26.4%). HPV-16 was the most prevalent type in both the anal canal (13.2% of women) and the cervix (5.1%). In multivariable analysis, factors associated with prevalent anal HR-HPV infection were CD4(+)count <350/μL (odds ratio, 2.9; 95% confidence interval, 1.3-6.5), concurrent cervical lesions (2.6; 1.0-4.3), and cervical HR-HPV infection (1.8; 1.0-3.2). The high prevalence of HR-HPV types, including HPV-16, in the anal canal of HIV-positive women is concerning. Anal cancer screening should be considered for HIV-positive women as part of their routine care. © The Author 2015.

Background Infections during pregnancy may have serious consequences for both mother and baby. Assessment of risk factors for infections informs planning of interventions and analysis of the impact of infections on health outcomes. Objectives To describe risk factors for helminths, malaria and HIV in pregnant Ugandan women before intervention in a trial of de-worming in pregnancy. Methods The trial recruited 2,507 pregnant women between April 2003 and November 2005. Participants were interviewed and blood and stool samples obtained; location of residence at enrolment was mapped. Demographic, socioeconomic, behavioral and other risk factors were modelled using logistic regression. Results There was a high prevalence of helminth, malaria and HIV infection, as previously reported. All helminths and malaria parasitemia were more common in younger women, and education was protective against every infection. Place of birth and/or tribe affected all helminths in a pattern consistent with the geographical distribution of helminth infections in Uganda. Four different geohelminths (hookworm, Trichuris, Ascaris and Trichostrongylus) showed a downwards trend in prevalence during the enrolment period. There was a negative association between hookworm and HIV, and between hookworm and low CD4 count among HIV-positive women. Locally, high prevalence of schistosomiasis and HIV occurred in lakeshore communities. Conclusions Interventions for helminths, malaria and HIV need to target young women both in and out of school. Antenatal interventions for malaria and HIV infection must continue to be promoted. Women originating from a high risk area for a helminth infection remain at high risk after migration to a lower-risk area, and vice versa, but overall, geohelminths seem to be becoming less common in this population. High risk populations, such as fishing communities, require directed effort against schistosomiasis and HIV infection. PMID:19564904

Deficits in verbal learning and memory are a prominent feature of neurocognitive function in HIV-infected women, and are associated with high levels of perceived stress. To understand the neurobiological factors contributing to this stress-related memory impairment, we examined the association between stress, verbal memory, and brain volumes in HIV-infected women. Participants included 38 HIV-infected women (Mean age=43.9years) from the Chicago Consortium of the Women's Interagency HIV Study (WIHS). Participants underwent structural magnetic resonance imaging (MRI) and completed standardized measures of verbal learning and memory and stress (Perceived Stress Scale-10; PSS-10). Brain volumes were evaluated in a priori regions of interest, including the medial temporal lobe (MTL) and prefrontal cortex (PFC). Compared to HIV-infected women with lower stress (PSS-10 scores in lower two tertiles), HIV-infected women with higher stress (scores in the top tertile), performed worse on measures of verbal learning and memory and showed smaller volumes bilaterally in the parahippocampal gyrus, superior frontal gyrus, middle frontal gyrus, and inferior frontal gyrus (p's<0.05). Reduced volumes in the inferior frontal gyrus, middle frontal gyrus, and superior frontal gyrus (all right hemisphere) were negatively associated with verbal learning and memory performance. Prefrontal cortical atrophy is associated with stress-related deficits in verbal learning and memory in HIV-infected women. The time course of these volume losses in relation to memory deficits has yet to be elucidated, but the magnitude of the volumetric differences between women with higher versus lower stress suggests a prolonged vulnerability due to chronic stress and/or early life trauma.

The use of injectable progestin-only contraceptives has been associated with increased risk of HIV acquisition in observational studies, but the biological mechanisms of this risk remain poorly understood. We aimed to assess the effects of progestins on HIV acquisition risk and the immune environment in the female genital tract. In this prospective cohort, we enrolled HIV-negative South African women aged 18-23 years who were not pregnant and were living in Umlazi, South Africa from the Females Rising through Education, Support, and Health (FRESH) study. We tested for HIV-1 twice per week to monitor incident infection. Every 3 months, we collected demographic and behavioural data in addition to blood and cervical samples. The study objective was to characterise host immune determinants of HIV acquisition risk, including those associated with injectable progestin-only contraceptive use. Hazard ratios (HRs) were estimated using Cox proportional hazards methods. Between Nov 19, 2012, and May 31, 2015, we characterised 432 HIV-uninfected South African women from the FRESH study. In this cohort, 152 women used injectable progestin-only contraceptives, 43 used other forms of contraception, and 222 women used no method of long-term contraception. Women using injectable progestin-only contraceptives were at substantially higher risk of acquiring HIV (12·06 per 100 person-years, 95% CI 6·41-20·63) than women using no long-term contraception (3·71 per 100 person-years, 1·36-8·07; adjusted hazard ratio [aHR] 2·93, 95% CI 1·09-7·868, p=0·0326). HIV-negative injectable progestin-only contraceptive users had 3·92 times the frequency of cervical HIV target cells (CCR5+ CD4 T cells) compared with women using no long-term contraceptive (p=0·0241). Women using no long-term contraceptive in the luteal phase of the menstrual cycle also had a 3·25 times higher frequency of cervical target cells compared with those in the follicular phase (p=0·0488), suggesting that a

Early defence mechanisms of innate immunity respond rapidly to infection against HIV-1 in the genital mucosa. Additionally, innate immunity optimises effective adaptive immune responses against persistent HIV infection. Recent research has highlighted the intrinsic roles of apolipoprotein B mRNA-editing, enzyme-catalytic, polypeptide-like 3G, tripartite motif-containing protein 5, tetherin, sterile α-motif and histidine/aspartic acid domain-containing protein 1 in restricting HIV-1 replication. Likewise, certain endogenously secreted antimicrobial peptides, namely α/β/θ-defensins, lactoferrins, secretory leukocyte protease inhibitor, trappin-2/elafin and macrophage inflammatory protein-3α are reportedly protective. Whilst certain factors directly inhibit HIV, others can be permissive. Interferon-λ3 exerts an anti-HIV function by activating Janus kinase-signal transducer and activator of transcription-mediated innate responses. Morphine has been found to impair intracellular innate immunity, contributing to HIV establishment in macrophages. Interestingly, protegrin-1 could be used therapeutically to inhibit early HIV-1 establishment. Moreover, chloroquine inhibits plasmacytoid dendritic cell activation and improves effective T-cell responses. This minireview summarizes the recently identified targets for innate immunity-mediated therapies and outlines the challenges that lie ahead in improving treatment of HIV infection. © 2012 The Societies and Blackwell Publishing Asia Pty Ltd.

In 2011, Tanzania adopted a policy for provision of daily co-trimoxazole prophylaxis to HIV-infected pregnant women for prevention of malaria and other opportunistic infections. As per the policy, HIV-infected pregnant women should not be given sulfadoxine-pyrimethamine (SP) for intermittent preventive therapy. The challenges associated with this policy change and the extent to which the new policy for prevention of malaria in pregnant women coinfected with HIV was implemented need to be assessed. To assess the implementation of malaria-preventive therapy policy among HIV-infected pregnant women in the public health facilities in Dar es Salaam, Tanzania. The study was conducted in Kinondoni Municipality, Dar es Salaam, Tanzania, from January 2015 to July 2015. Three hundred and fifty-three HIV-infected pregnant women who were attending antenatal clinics (ANCs) and using co-trimoxazole for prevention of malaria were interviewed. Twenty-six health care workers working at the ANCs were also interviewed regarding provision of co-trimoxazole prophylaxis to pregnant women. A knowledge scale was used to grade the level of knowledge of health care providers. Focus group discussions were also conducted with 18 health care workers to assess the level of implementation of the policy and the challenges encountered. Twenty-three (6.5%) pregnant women with known HIV serostatus were using co-trimoxazole for prevention of opportunistic infections even before they became pregnant. Out of the 353 HIV-infected pregnant women, eight (2.5%) were coadministered with both SP and co-trimoxazole. Sixty (16.7%) pregnant women had poor adherence to co-trimoxazole prophylaxis. Out of the 26 interviewed health care providers, 20 had high level of knowledge regarding malaria-preventive therapy in HIV-infected pregnant women. Lack of adequate supply of co-trimoxazole in health facilities and inadequate training of health care providers were among the factors causing poor implementation of co

Background Home delivery, referring to pregnant women giving birth in the absence of a skilled birth attendant, is a significant contributor to maternal mortality, and is encouragingly reported to be on a decline in the general population in resource limited settings. However, much less is known about home delivery amongst HIV-infected women in sub-Saharan Africa (sSA). We described the prevalence and correlates of home delivery among HIV-infected women attending care at a rural public health facility in Kilifi, Coastal Kenya. Methods A cross-sectional design using mixed methods was used. Quantitative data were collected using interviewer-administered questionnaires from HIV-infected women with a recent pregnancy (within 5 years, n = 425), whilst qualitative data were collected using focused group discussions (FGD, n = 5). Data were analysed using logistic regression and a thematic framework approach respectively. Results Overall, 108 (25.4%, [95% CI: 21.3–29.8]) participants delivered at home. Correlates of home delivery included lack of formal education (aOR 12.4 [95% CI: 3.4–46.0], p<0.001), history of a previous home delivery (2.7 [95% CI:1.2–6.0], p = 0.019) and being on highly active antiretroviral therapy (HAART, 0.4 [95% CI:0.2–0.8], p = 0.006).Despite a strong endorsement against home delivery, major thematic challenges included consumer-associated barriers, health care provider associated barriers and structural barriers. Conclusion A quarter of HIV-infected women delivered at home, which is comparable to estimates reported from the general population in this rural setting, and much lower than estimates from other sSA settings. A tailored package of care targeting women with no formal education and with a history of a previous home delivery, coupled with interventions towards scaling up HAART and improving the quality of maternal care in HIV-infected women may positively contribute to a decline in home delivery and subsequent maternal mortality in

Placental cytokine balance may be critical for the control of mother-to-child transmission (MTCT) of HIV. We assessed whether the type and duration of antiretrovirals used for prevention of HIV-1-MTCT modified the inflammatory cytokine profile. We investigated the levels of cytokine expression in the placentas of 61 HIV-1-infected women who received zidovudine (ZDV) plus single dose nevirapine (SD-NVP) or ZDV only for prevention of MTCT. Placentas of 38 HIV-1-uninfected women were included as controls. All placentas were obtained after vaginal delivery. Levels of mRNA and cytokine expression were quantified using real-time PCR and ELISA, respectively, in placental explants and 24-hour culture supernatants and analyzed in relation to the women's characteristics and the type and duration of antiretroviral prophylaxis. HIV-1-infected and uninfected women did not show any differences in the expression of placental cytokine secretion except for a trend toward lower TNF-alpha mRNA levels in HIV-1-infected women. Within the HIV-1-infected group, women who were exposed to a long duration of ZDV (>72 days) or received SD-NVP less than 5h prior to delivery, more frequently expressed detectable levels of IL-10 in their placentas (32% versus 7% (p = 0.01) and 32% versus 5% (p = 0.02), respectively). No infant was found to be HIV-1-infected. Our results showed a normalization of the placental cytokine balance in HIV-1-infected women receiving antiretroviral prophylaxis. Furthermore, the type and duration of antiretroviral prophylaxis have an impact on the placental anti-inflammatory IL-10 expression level, which may contribute to controlling HIV replication at the placental level, thus reducing MTCT of HIV-1.

Objective To determine predictors of treatment failure and recurrence after surgical excisional procedures for CIN in HIV-infected women. Methods A retrospective cohort study was conducted in which 136 eligible HIV-infected women treated for CIN between 1999 and 2005 were included. Data were abstracted from charts and computer databases. Treatment failures were defined as the presence of CIN 1+ at initial follow-up. Recurrences were defined as the presence of CIN 1+ subsequent to initial normal follow-up. Results Treatment failure at initial follow-up was common, occurring in 51% of CIN 1 and 55% of CIN 2+. Most lesions detected at treatment failure were high grade (>70%), regardless of the grade of initial lesion. Significant risk factors for treatment failure were loop electrosurgical excision procedure (LEEP) compared to cold knife conization (RR=1.76; 95% CI: 1.15–2.64), and low CD4+ count (p = 0.04). Among those with an initial normal clinical evaluation, 55% eventually recurred. As with treatment failure, most lesions detected at recurrence were high grade. Risk factors for recurrence included use of LEEP (hazard ratio [HR] = 3.38; 95% CI: 1.55–7.39), higher HIV RNA level, and the presence of positive margins at treatment (HR = 6.12; 95% CI: 1.90–19.73). Conclusions Most CIN treatment of HIV-infected women studied either failed or resulted in recurrence. Of particular concern, many of these subsequent lesions were high grade. Conization, however, was associated with significantly less failure/recurrence than LEEP. Clinicians treating CIN in HIV-infected women should avoid raising expectations of cure and instead focus on the achievable goal of cancer prevention until there are better therapies for this patient population.

To test the hypothesis that the selective serotonin reuptake inhibitor (SSRI) citalopram would down-regulate human immunodeficiency virus (HIV) infectivity and that the greatest effects would be seen in people with depression. Depression is a risk factor for morbidity and mortality in HIV/acquired immune deficiency syndrome. Serotonin (5-HT) neurotransmission has been implicated in the pathobiology of depression, and pharmacologic therapies for depression target this system. The 5-HT transporter and 5-HT receptors are widely distributed throughout the central nervous and immune systems. Depression has been associated with suppression of natural killer cells and CD8(+) lymphocytes, key regulators of HIV infection. Ex vivo models for acute and chronic HIV infection were used to study the effects of citalopram on HIV viral infection and replication in 48 depressed and nondepressed women. For both the acute and chronic infection models, HIV reverse transcriptase activity was measured in the citalopram treatment condition and the control condition. The SSRI significantly down-regulated the reverse transcriptase response in both the acute and chronic infection models. Specifically, citalopram significantly decreased the acute HIV infectivity of macrophages. Citalopram also significantly decreased HIV viral replication in the latently infected T-cell line and in the latently infected macrophage cell line. There was no difference in down-regulation by depression status. These studies suggest that an SSRI enhances natural killer/CD8 noncytolytic HIV suppression in HIV/acquired immune deficiency syndrome and decreases HIV viral infectivity of macrophages, ex vivo, suggesting the need for in vivo studies to determine a potential role for agents targeting serotonin in the host defense against HIV.

Introduction Neighborhood characteristics shape sexual risk in HIV-uninfected adults in the United States (US). We assess relationships between census tract characteristics and sexual risk behaviors in a predominantly HIV-infected cohort of women living in the Southern US. Methods This cross-sectional multilevel analysis included data from 737 HIV-infected and HIV-uninfected women enrolled in the Women’s Interagency HIV Study. Administrative data captured characteristics of census tracts where women lived; participant-level data were gathered via survey. We used principal components analysis to condense tract-level variables into components: social disorder (e.g., violent crime rate) and social disadvantage (e.g., alcohol outlet density). We used hierarchical generalized linear models to assess relationships between tract-level characteristics and condomless vaginal intercourse (CVI), anal intercourse (AI), and condomless anal intercourse (CAI). Results Greater social disorder was associated with less AI (OR=0.63, 95% CI=0.43, 0.94) and CAI (OR=0.49, 95% CI=0.30, 0.80), regardless of HIV status. There were no statistically significant additive or multiplicative interactions between tract characteristics and HIV status. Conclusion Neighborhood characteristics are associated with sexual risk behaviors among women living in the Southern US, these relationships do not vary by HIV status. Future studies should establish temporality and explore the causal pathways through which neighborhoods influence sexual risk. PMID:28476327

Compare the anti-T. gondii IgG titer between HIV-1 infected and non HIV-1 infected pregnant women and report three cases of congenital toxoplasmosis resulting from reactivation of infection during pregnancy of HIV-1 infected women. This study was conducted among 2,270 pregnant women with chronic Toxoplasma gondii infection (absence of IgM and presence of IgG), including 82 HIV-1 infected and 2,188 non-infected women. The average anti-T. gondii IgG titer was 127 for the 2,188 non-HIV-1 infected women, and 227 for the 82 HIV-1-infected women (p = 0,007). These results suggested that higher anti-T. gondii IgG titers in HIV-1-infected pregnant women may not be indicative of an elevated risk for fetal infection. In this study three cases of congenital toxoplasmosis that resulted from infection reactivation during pregnancy of HIV-1-infected women were manifested by fetal death, symptomatic infection, and infant without symptoms, respectively. In two of these women, a ten-fold increase in IgG levels above used cutoff was observed (2,320 UI/mL and 3,613 UI/mL, respectively). In the third pregnant women anti-T. gondii IgG titers during pregnancy did not rise despite the occurrence of congenital toxoplasmosis (204; 198; 172 UI/mL). Congenital toxoplasmosis resulting reactivation of infection during pregnancy in the studied group leads us to believe that it is a public health problem, especially in our population, in which seroprevalence of T. gondii infections is high. These findings also suggest that special attention is necessary during pregnancy, because the serologic diagnosis may not be indicative of toxoplasmosis reactivation.

Food insecurity, insufficient quality and quantity of nutritionally adequate food, affects millions of people in the United States (US) yearly, with over 18 million Americans reporting hunger. Food insecurity is associated with obesity in the general population. Due to the increasing prevalence of obesity and risk factors for cardiovascular disease among HIV-infected women, we sought to determine the relationship between food insecurity and obesity in this cohort of urban, HIV-infected and -uninfected but at risk women. Using a cross-sectional design, we collected data on food insecurity, body mass index and demographic and clinical data from 231 HIV-infected and 119 HIV-negative women enrolled in Bronx site of the Women's Interagency HIV Study (WIHS). We used multivariate logistic regression to identify factors associated with obesity. Food insecurity was highly prevalent, with almost one third of women (110/350, 31%) reporting food insecurity over the previous six months and over 13% of women reported food insecurity with hunger. Over half the women were obese with a Body Mass Index (BMI) of ≥ 30. In multivariate analyses, women who were food insecure with hunger had higher odds of obesity (Adjusted odds ratio [aOR] =  2.56, 95% Confidence Interval [CI]  =  1.27, 5.20) after adjusting for HIV status, age, race, household status, income, drug and alcohol use. Food insecurity with hunger was associated with obesity in this population of HIV-infected and -uninfected, urban women. Both food insecurity and obesity are independent markers for increased mortality; further research is needed to understand this relationship and their role in adverse health outcomes.

Background. Anal cancer is one of the most common cancers affecting individuals infected with human immunodeficiency virus (HIV), although few have evaluated rates separately for men who have sex with men (MSM), other men, and women. There are also conflicting data regarding calendar trends. Methods. In a study involving 13 cohorts from North America with follow-up between 1996 and 2007, we compared anal cancer incidence rates among 34 189 HIV-infected (55% MSM, 19% other men, 26% women) and 114 260 HIV-uninfected individuals (90% men). Results. Among men, the unadjusted anal cancer incidence rates per 100 000 person-years were 131 for HIV-infected MSM, 46 for other HIV-infected men, and 2 for HIV-uninfected men, corresponding to demographically adjusted rate ratios (RRs) of 80.3 (95% confidence interval [CI], 42.7–151.1) for HIV-infected MSM and 26.7 (95% CI, 11.5–61.7) for other HIV-infected men compared with HIV-uninfected men. HIV-infected women had an anal cancer rate of 30/100 000 person-years, and no cases were observed for HIV-uninfected women. In a multivariable Poisson regression model, among HIV-infected individuals, the risk was higher for MSM compared with other men (RR, 3.3; 95% CI, 1.8–6.0), but no difference was observed comparing women with other men (RR, 1.0; 95% CI, 0.5–2.2). In comparison with the period 2000–2003, HIV-infected individuals had an adjusted RR of 0.5 (95% CI, .3–.9) in 1996–1999 and 0.9 (95% CI, .6–1.2) in 2004–2007. Conclusions. Anal cancer rates were substantially higher for HIV-infected MSM, other men, and women compared with HIV-uninfected individuals, suggesting a need for universal prevention efforts. Rates increased after the early antiretroviral therapy era and then plateaued. PMID:22291097

Women living with HIV are at increased risk to be co-infected with HPV, persistent high-risk (HR) human papillomavirus (HPV) infection and increased HR HPV viral load, which make them more at risk for cervical cancer. Despite their inherent vulnerability, there is a scarcity of data on potential high risk (pHR) and HR HPV genotypes in HIV- infected women with cervical dysplasia and HPV-type specific viral load in this population in Sub Saharan Africa. The aim of this analysis of HIV-infected women was to explore the virological correlates of high-grade cervical dysplasia (CIN 2+) in HIV-infected women, thereby profiling HPV genotypes. This analysis assesses baseline data obtained from a cohort study of 74 HIV-infected women with abnormal cytology attending a Comprehensive Care Centre for patients with HIV infection in Mombasa, Kenya. Quantitative real-time PCR was used for HPV typing and viral load. CIN 2 was observed in 16% (12/74) of women, CIN 3 in 23% (17/74), and, invasive cervical carcinoma (ICC) in 1% (1/74) of women. In women with CIN 3+, HPV 16 (44%), HPV 56 (33%), HPV 33 and 53 (HPV 53 (28%) were the most prevalent genotypes. HPV 53 was observed as a stand-alone HPV in one woman with ICC. A multivariate logistic regression adjusting for age, CD4 count and HPV co-infections suggested the presence of HPV 31 as a predictor of CIN 2+ (adjusted odds ratio [aOR]:4.9; p = 0.05; 95% (Confidence Interval) [CI]:1.03-22.5). Women with CIN2+ had a significantly higher viral log mean of HPV 16, (11.2 copies/ 10,000 cells; 95% CI: 9.0-13.4) than with CIN 1. The high prevalence of HPV 53 in CIN 3 and as a stand-alone genotype in the patient with invasive cervical cancer warrants that its clinical significance be further revisited among HIV-infected women. HPV 31, along with elevated means of HPV 16 viral load were predictors of CIN 2 + .

Immunology of Pediatric HIV Infection

Summary Most infants born to human immunodeficiency virus (HIV)-infected women escape HIV infection. Infants evade infection despite an immature immune system and, in the case of breastfeeding, prolonged repetitive, exposure. If infants become infected, the course of their infection and response to treatment differs dramatically depending upon the timing (in utero, intrapartum, or during breastfeeding) and potentially the route of their infection. Perinatally acquired HIV infection occurs during a critical window of immune development. HIV’s perturbation of this dynamic process may account for the striking age-dependent differences in HIV disease progression. HIV infection also profoundly disrupts the maternal immune system upon which infants rely for protection and immune instruction. Therefore, it is not surprising that infants who escape HIV infection still suffer adverse effects. In this review, we highlight the unique aspects of pediatric HIV transmission and pathogenesis with a focus on mechanisms by which HIV infection during immune ontogeny may allow discovery of key elements for protection and control from HIV.

Human immunodeficiency virus (HIV) increases susceptibility to Plasmodium falciparum infection, and this has most clearly been demonstrated in pregnant women. Variant surface antigens on the surfaces of erythrocytes infected with P. falciparum are major targets of protective immunity. We studied the impact of HIV infection on pregnant women's humoral immunity to variant surface antigens expressed by placental and pediatric isolates of P. falciparum. By flow cytometry, sera from HIV-infected women more frequently lacked antibodies to these antigens than sera from HIV-uninfected women. This difference was similar in magnitude for pediatric isolates (unadjusted odds ratio [OR] = 6.36; 95% confidence interval [CI] = 1.14, 35.32; P < 0.05) and placental isolates (unadjusted OR = 6.47; 95% CI = 0.75, 55.64; P < 0.10). We divided women into high and low responders on the basis of their antibody levels. After adjustment for CD4 count, maternal age, and gravidity, we found that HIV-infected women more frequently had low responses to both pediatric isolates (OR = 5.34; 95% CI = 1.23, 23.16; P = 0.025) and placental isolates (OR = 4.14; 95% CI = 1.71, 10.02; P = 0.002). The relative quantity of antibodies to both pediatric isolates (P = 0.035) and placental isolates (P = 0.005) was lower in HIV-infected women than in HIV-uninfected women. HIV infection has a broad impact on variant-specific immunity, which may explain the susceptibility of infected individuals to clinical malaria episodes. PMID:18199738

HIV/AIDS in Older Women: Unique Challenges, Unmet Needs

As persons living with HIV/AIDS live longer, both the prevalence and incidence of HIV infection in older women is expected to increase, and this review presents a model and review of the extant literature on older women with HIV/AIDS in the United States. Older women are rarely addressed in the discourse about HIV risk and prevention, and their concerns are often missed by risk reduction programs that typically target men and younger adults. Societal biases around aging can compound factors such as stigma and disclosure for older women. Primary care providers are often not recommending routine HIV testing to older women, or addressing the impact of age related physiological changes on risk and sexual health. Many older women may be starting new relationships and the role of relational variables that are specific to this group of women are key in understanding prevention and treatment. Empirical research focused on the needs of older women, and recognition of the diverse composition and needs of this group is needed to inform prevention, intervention and best practices with this population of women.

Aging is associated with immune dysfunction and the related development of conditions with an inflammatory pathogenesis. Some of these immune changes are also observed in HIV infection, but the interaction between immune changes with aging and HIV infection are unknown. Whilst sex differences in innate immunity are recognized, little research into innate immune aging has been performed on women. This cross-sectional study of HIV positive and negative women used whole blood flow cytometric analysis to characterize monocyte and CD8(+) T cell subsets. Plasma markers of innate immune activation were measured using standard ELISA-based assays. HIV positive women exhibited elevated plasma levels of the innate immune activation markers CXCL10 (p<0.001), soluble CD163 (sCD163, p = 0.001), sCD14 (p = 0.022), neopterin (p = 0.029) and an increased proportion of CD16(+) monocytes (p = 0.009) compared to uninfected controls. Levels of the innate immune aging biomarkers sCD163 and the proportion of CD16(+) monocytes were equivalent to those observed in HIV negative women aged 14.5 and 10.6 years older, respectively. CXCL10 increased with age at an accelerated rate in HIV positive women (p = 0.002) suggesting a synergistic effect between HIV and aging on innate immune activation. Multivariable modeling indicated that age-related increases in innate immune biomarkers CXCL10 and sCD163 are independent of senescent changes in CD8(+) T lymphocytes. Quantifying the impact of HIV on immune aging reveals that HIV infection in women confers the equivalent of a 10-14 year increase in the levels of innate immune aging markers. These changes may contribute to the increased risk of inflammatory age-related diseases in HIV positive women.

We longitudinally assessed predictors of insulin resistance (IR) change among HIV-uninfected and HIV-infected (ART-initiators and ART-non-initiators) Rwandan women. HIV-infected (HIV+) and uninfected (HIV-) women provided demographic and clinical measures: age, body mass index (BMI) in Kg/(height in meters)2, Fat-Mass (FMI) and Fat-Free-Mass (FFMI) index, fasting serum glucose and insulin. Homeostasis Model Assessment (HOMA) was calculated to estimate IR change over time in log10 transformed HOMA measured at study enrollment or prior to ART initiation in 3 groups: HIV- (n = 194), HIV+ ART-non-initiators (n=95) and HIV+ ART-initiators (n=371). ANCOVA linear regression models of change in log10-HOMA were fit with all models included the first log10 HOMA as a predictor. Mean±SD log10-HOMA was -0.18±0.39 at the 1st and -0.21±0.41 at the 2nd measure, with mean change of 0.03±0.44. In the final model (all women) BMI at 1st HOMA measure (0.014; 95% CI=0.006-0.021 per kg/m2; p<0.001) and change in BMI from 1st to 2nd measure (0.024; 95% CI=0.013-0.035 per kg/m2; p<0.001) predicted HOMA change. When restricted to subjects with FMI measures, FMI at 1st HOMA measure (0.020; 95% CI=0.010-0.030 per kg/m2; p<0.001) and change in FMI from 1st to 2nd measure (0.032; 95% CI=0.020-0.043 per kg/m2; p<0.0001) predicted change in HOMA. While ART use did not predict change in log10-HOMA, untreated HIV+ women had a significant decline in IR over time. Use or duration of AZT, d4T and EFV was not associated with HOMA change in HIV+ women. Baseline BMI and change in BMI, and in particular fat mass and change in fat mass predicted insulin resistance change over ~3 years in HIV-infected and uninfected Rwandan women. Exposure to specific ART (d4T, AZT, EFV) did not predict insulin resistance change in ART-treated HIV-infected Rwandan women.

In 1996, nearly 60% of U.S. AIDS cases among Latinas were attributed to unprotected sex with men. Economic disadvantage, language barriers, and strong cultural gender norms regarding sex exacerbate the risk for HIV infection among Latina immigrant women. Through a collaboration among scientists and providers, this study was designed to evaluate the impact of a multifaceted empowerment program for Latina immigrant women on HIV risk behaviors. Women (N = 74) were followed for the first 6 months of their participation and attended up to nine distinct types of activities (e.g., information meetings, friendship circles, and workshops). Although the program was not developed to specifically target HIV risk behaviors, women showed significant increases in sexual communication comfort, were less likely to maintain traditional sexual gender norms, and reported changes in decision-making power. Targeting broader sociocultural issues may increase the necessary skills for Latina women to prevent HIV infection from their sexual partners. Successful collaborations between scientists and providers are critical in developing effective, community-relevant interventions.

Problem High-risk human papillomavirus (HR-HPV) is prevalent in HIV-infected women and may be associated with mucosal changes that promote HIV replication. Method of Study Innate immune molecules, antimicrobial activity, HIV RNA, and HPV DNA genotypes were measured in a cross-sectional study of 128 HIV-infected women categorized into HPV-16 (n=8), other HR-HPV (n=41), and non-HR-HPV controls (n=79). Results Compared to controls, HR-HPV groups had higher plasma viral loads (p=0.004), lower CD4 cells (p=0.02), more genital tract HIV RNA (p=0.03), greater number of different HPV types (p<0.001), higher cervicovaginal lavage (CVL) IL-1α (p=0.03) and human beta defensin 2 (HBD2) (p=0.049), and less anti-HIVBal activity (p=0.03). HPV-16 remained significantly associated with higher HBD2 (p=0.03), higher IL-1α (p=0.009), and lower anti-HIVBaL activity (p=0.03) compared to controls after adjusting for plasma viral load and CD4 T cell count. Conclusion HR-HPV is associated with mucosal changes in HIV-infected women that could adversely impact genital tract health. PMID:26685115

Ukraine's injecting drug use-driven HIV epidemic is among the most severe in Europe with high burden of HCV co-infection. HIV/HCV co-infected individuals are at elevated risk of HCV-related morbidity, but little is known about burden of liver disease and associated factors in the HIV-positive population in Ukraine, particularly among women. Characteristics of 2050 HIV-positive women enrolled into the Ukrainian Study of HIV-infected Childbearing Women were described by HCV serostatus. Aspartate transaminase (AST) to platelet ratio (APRI) and FIB-4 scores were calculated and exact logistic regression models fitted to investigate factors associated with significant fibrosis (APRI >1.5) among 762 women with an APRI score available. Of 2050 HIV-positive women (median age 27.7 years, IQR 24.6-31.3), 33% were HCV co-infected (79% of those with a history of injecting drug use vs 23% without) and 17% HBsAg positive. A quarter were on antiretroviral therapy at postnatal cohort enrolment. 1% of the HIV/HCV co-infected group had ever received treatment for HCV. Overall, 24% had an alanine aminotransferase level >41 U/L and 34% an elevated AST (53% and 61% among HIV/HCV co-infected). Prevalence of significant fibrosis was 4.5%; 2.5% among 445 HIV mono-infected and 12.3% among 171 HIV/HCV co-infected women. 1.2% had a FIB-4 score >3.25 indicating advanced fibrosis. HCV RNA testing in a sub-group of 56 HIV/HCV co-infected women indicated a likely spontaneous clearance rate of 18% and predominance of HCV genotype 1, with one-third having genotype 3 infection. Factors associated with significant fibrosis were HCV co-infection (AOR 2.53 95%CI 1.03-6.23), history of injecting drug use (AOR 3.51 95%CI 1.39-8.89), WHO stage 3-4 HIV disease (AOR 3.47 95%CI 1.51-7.99 vs stage 1-2 HIV disease) and not being on combination antiretroviral therapy (AOR 3.08 95%CI 1.23-7.74), adjusted additionally for HBV co-infection, smoking and age. Most HIV/HCV co-infected women had elevated liver

This study examined the experiences and perceived benefits of support group participation among HIV-infected women in South Africa. From a qualitative analysis of responses, key psychological processes through which support groups are potentially beneficial were identified. These processes included: identification; modeling; acceptance; and empowerment. The participants’ consequent life changes were explored in order to associate these processes with the positive outcomes of support group participation. Through understanding the relationship between the psychological processes within a support group setting and the potential benefits, and by targeting these processes in the development and implementation of future support group interventions, a framework is provided for achieving positive outcomes associated with support group participation.

Most women who live in sub-Saharan countries have heard of HIV/AIDS, but there is still widespread misunderstanding about how HIV is spread, the consequences of infection, and how to protect against infection. The aim of the present study was to investigate knowledge about HIV and attitudes towards condom use in West African refugees who had settled in Perth, Western Australia, within the past 5 years. Knowledge about transmission of HIV, myths about how HIV is spread, incorrect beliefs about protective factors, the effectiveness of condoms in protecting against sexually transmissible infections, and attitudes towards condom use were investigated by survey in 51 West African women, and in 100 Australian women for comparison. Where possible, each West African woman was matched for age and level of education with an Australian woman. Knowledge of HIV was poorest in the least educated West African women, but many of the more highly educated women also had misconceptions about how HIV is spread, how to protect against HIV, and the effectiveness of condoms in protecting against HIV. Moreover, most West African women held negative attitudes towards condom use. Within the Australian sample, HIV knowledge was greatest in women with tertiary qualifications, and was greater in younger than older women; in addition, attitudes towards condom use differed across the age span. The findings in the present study suggest that educational programs that focus on knowledge about HIV should be tailored to meet the needs and cultural sensitivities of newly emerging immigrant communities, and should target particular demographic groups within the Australian population.

Background In 2011, Tanzania adopted a policy for provision of daily co-trimoxazole prophylaxis to HIV-infected pregnant women for prevention of malaria and other opportunistic infections. As per the policy, HIV-infected pregnant women should not be given sulfadoxine-pyrimethamine (SP) for intermittent preventive therapy. The challenges associated with this policy change and the extent to which the new policy for prevention of malaria in pregnant women coinfected with HIV was implemented need to be assessed. Aim To assess the implementation of malaria-preventive therapy policy among HIV-infected pregnant women in the public health facilities in Dar es Salaam, Tanzania. Methodology The study was conducted in Kinondoni Municipality, Dar es Salaam, Tanzania, from January 2015 to July 2015. Three hundred and fifty-three HIV-infected pregnant women who were attending antenatal clinics (ANCs) and using co-trimoxazole for prevention of malaria were interviewed. Twenty-six health care workers working at the ANCs were also interviewed regarding provision of co-trimoxazole prophylaxis to pregnant women. A knowledge scale was used to grade the level of knowledge of health care providers. Focus group discussions were also conducted with 18 health care workers to assess the level of implementation of the policy and the challenges encountered. Results Twenty-three (6.5%) pregnant women with known HIV serostatus were using co-trimoxazole for prevention of opportunistic infections even before they became pregnant. Out of the 353 HIV-infected pregnant women, eight (2.5%) were coadministered with both SP and co-trimoxazole. Sixty (16.7%) pregnant women had poor adherence to co-trimoxazole prophylaxis. Out of the 26 interviewed health care providers, 20 had high level of knowledge regarding malaria-preventive therapy in HIV-infected pregnant women. Lack of adequate supply of co-trimoxazole in health facilities and inadequate training of health care providers were among the factors

Introduction Perinatal and horizontal transmission of Hepatitis B occur in areas of high endemicity as most infections are acquired in the first 5 years of life. Unless Hepatitis B and C infected pregnant women identified, and appropriate treatment provided, children born to these women are at high risk of chronic Hepatitis B (and C) virus infection. The objecive of this study was to determined the prevalence and the factors associated with Hepatitis B and C Virus infection in pregnant HIV positive Nigerians. Methods A cross sectional study among HIV Positive pregnant women seen at a large PMTCT clinic in Lagos Nigeria. The women were screened for Hepatitis B and C Virus infection at enrollment. HIV viral load, CD4 count, liver transaminases and hemoglobin levels were also determined. Data were managed with SPSS for windows version. Ethical approval was obtained from the Institutions Ethical Review Board. Results Of the 2391 studied subjects, 101(4.2%) and 37(1.5%) respectively were seropositive for Hepatitis B and C Virus infection. Twowomen (0. 08%) had triple infections. blood transfusion, (cOR: 2.3; 95% CI:1.1 - 4.6), history of induced abortion (cOR:2. 2;95% CI:1.3 - 3.6), and elevated baseline ALT (cOR:2. 2; 95%CI:2. 2;4.2) were significantly associated with HBV. History of induced abortion was the only factor found to be associated with HIV/ HCV (cOR: 1.9;95%CI:1. 3-3.9). Conclusion Hepatitis B Virus infection (4.2%) is relatively common in our environment and associated with induced abortion, blood transfusion and elevated baseline transaminase. Hepatitis C Virus infection (1.5%) is less common and associated with only history of induced abortion. PMID:25396023

Abstract In epidemiologic studies, human immunodeficiency virus (HIV)-infected men on antiretroviral therapy (ART) are at higher risk of incident diabetes mellitus compared with women with similar treatment histories. We used metabolomics to determine whether a sex difference in plasma amino acids, acylcarnitines, and organic acids predictive of diabetes and impaired energy metabolism is present in HIV-infected persons on long-term ART. We enrolled 70 HIV-infected adults (43% women) on efavirenz, tenofovir, and emtricitabine (Atripla) with HIV-1 RNA <50 copies/mL for over 2 years. Half of the HIV-infected subjects were obese, and these were matched with 30 obese HIV-negative controls. All subjects had no history of diabetes, statin use, or heavy alcohol use. Fasting insulin sensitivity was measured using homeostatic model assessment 2 (HOMA2), and adipose tissue was measured using dual-energy x-ray absorptiometry (DEXA). Liquid chromatography/mass spectrometry was used to quantitate fasting plasma branched chain and aromatic amino acids predictive of incident diabetes, and C3 and C5 acylcarnitinines and organic acids indicative of impaired energy metabolism. HIV-infected women had more baseline risk factors for insulin resistance: women were older (46 vs 44 years) and had a longer ART duration (8.4 vs 5.1 years, P < 0.05 for both) compared with men but had similar CD4+ count (median 701 cells/μL), smoking and hepatic C prevalence, and body mass index (BMI) (median 30.3 kg/m2). However, women had higher insulin sensitivity compared with men (P < 0.01), and lower plasma levels of isoleucine, leucine, valine, phenylalanine, and tyrosine (P < 0.01 for all), and lower C3 and C5 acylcarnitines (P < 0.01 for all), in multivariable regression models after adjusting for DEXA fat mass index, age, race, CD4+ count, smoking, and ART duration.
