Ocular and Adnexal Diseases in Human Immunodeficiency Virus-Infected Pregnant Women Attending HIV Clinics in Ibadan, Nigeria

Abstract Background: Human immunodeficiency virus (HIV) is a lentivirus. It is transmitted through sexual intercourse, shared intravenous drugs, contaminated needle use, blood transfusion, and mother-to-child transmission. Of the patients with HIV, 50%–75% have ocular manifestations and this may be the primary presentation. This study was carried out in two prevention of mother-to-child transmission (PMTCT)/HIV clinics. The aim was to determine the incidence, patterns of presentation, and determinants of ocular and adnexal diseases in HIV-positive pregnant women attending HIV clinics to develop an eye care protocol for them. Materials and Methods: The study was a cross-sectional study of HIV-positive pregnant women attending the PMTCT/HIV Clinics at University College Hospital and Adeoyo Maternity Teaching Hospital, Ibadan. Patients were interviewed using a structured questionnaire. Blood samples were taken for CD4+ count and viral load. The stage of the disease, type of antiretroviral therapy (ART), and the interval between HIV diagnosis and commencement of ART were recorded. Comprehensive ocular examination, which included visual acuity check unaided and with pinhole, lid, anterior segment examination with slit lamp and posterior segment examination with dilated binocular indirect ophthalmoscopy, was conducted. Statistical Package for Social Sciences version 23 was used to analyse the data. Results: A total of 153 pregnant women aged 23–42 years (mean, 33.5; standard deviation, ±5.6) were recruited. One hundred and fifteen (75.2%) of them were married in a monogamous setting. Multiple sexual partners (48.4%; n = 74—some women married in monogamous settings at the time of recruitment for this study had multiple sexual partners in the past) and the use of unsterilised objects (46.4%; n = 71) were major high-risk behaviours. Ocular and adnexal diseases were found in 81 (53%) participants. HIV-related ocular and adnexal diseases were found in 16 (10%) participants. Of the 16 HIV-related diseases, optic atrophy was found in seven (43.8%), presumed toxoplasmosis in three (18.7%), presumed cytomegalovirus retinitis in three (18.7%) lid warts in two (12.5%), and conjunctival microangiopathy in one (6.3%) participant. The association between HIV- related ocular and adnexal diseases and gestational age, CD4+ count, viral load and type of ART was not statistically significant. Conclusion: The few HIV-related findings in this study could be a result of the improved CD+ count/low viral load of most of the recruited participants. Ensuring that patients attending PMTCT/HIV clinic have at least one ocular examination during pregnancy by collaborating with eyecare professionals could ensure prompt detection and treatment of eye diseases, to improve the quality of life of HIV-positive pregnant women.

Significant Associations between Chlamydia trachomatis and Neisseria gonorrhoeae Infections in Human Immunodeficiency Virus-Infected Pregnant Women.

There is a lack of data on the burden of Chlamydia trachomatis and Neisseria gonorrhoeae among human immunodeficiency virus- (HIV-) infected pregnant women in South Africa. We conducted a cross-sectional study which included 385 HIV-infected pregnant women attending antenatal clinic at the King Edward VIII Hospital in Durban, South Africa. The women provided vaginal swabs which were tested for C. trachomatis and N. gonorrhoeae. The prevalence of the individual STIs was as follows: C. trachomatis (47/385, 12.2%) and N. gonorrhoeae (16/385, 4.1%). Having a circumcised partner, testing positive for N. gonorrhoeae, and perceiving themselves of being at risk for infection were shown to increase the risk for C. trachomatis infection. Without controlling for the other factors, testing positive for N. gonorrhoeae increased the risk for C. trachomatis infection by 10-fold (OR: 10.17, 95% CI: 3.39-29.66, p < 0.001). Similarly, adjusting for the other factors, the risk for C. trachomatis infection in women who tested positive for N. gonorrhoeae was 9-fold (OR: 9.16, 95% CI: 2.19-40.18, p = 0.003). The following factors were associated with the increased risk of N. gonorrhoeae infection: not knowing their partner's HIV status, partner having other partners, and C. trachomatis infection status. Without controlling for the other factors, testing positive for C. trachomatis increased the risk for N. gonorrhoeae infection by 6-fold (OR: 6.52, 95% CI: 2.22-18.49, p < 0.001). Similarly, adjusting for the other factors, the risk for N. gonorrhoeae infection in women who tested positive for C. trachomatis was 6-fold (OR: 6.09, 95% CI: 1.73-22.03, p = 0.005). We found a significant association between C. trachomatis and N. gonorrhoeae in the pregnant women and the risk factors associated with these pathogens. Future studies are urgently required to investigate the impact of C. trachomatis/N. gonorrhoeae coinfections in HIV pregnant women since this data is lacking in our setting. In addition, etiological screening of C. trachomatis and N. gonorrhoeae during antenatal clinic is urgently required to prevent adverse pregnancy and birth outcomes associated with these infections.

HIV and pregnancy: realities of XXI century

The human immunodeficiency virus (HIV) continues to be a major global public health issue, having claimed 34 million lives so far. 38 million people are living with HIV around the world. 2 million of these people are children. The high medical, social and economic significance of HIV infection is determined by the widespread and severe course of the disease. Every year, up to 2.7 million new infections are registered worldwide. Up to 30 % of cases of HIV infection in pregnant women are detected for the first time during pregnancy-related examinations. Every year, 1.49 million babies are born to HIV-positive women worldwide. The current tasks are to preserve the health of women and reduce the risk of transmission of HIV infection from mother to child. The article analyzes the results of Russian and foreign studies concerning the problems of pregnant HIV-positive women, published in international databases. The aim of the work is to analyze the data of studies aimed at studying the effect of HIV infection on the course of pregnancy.

Persistent Immune Activation in Human Immunodeficiency Virus-Infected Pregnant Women Starting Combination Antiretroviral Therapy After Conception.

This study evaluated the impact of human immunodeficiency virus (HIV) and combination antiretroviral therapy (cART) on immune activation during pregnancy in a Zambian cohort of HIV-exposed but uninfected children followed up from birth. Activated CD8+ T cells (CD38+ and HLA-DR+) were compared among HIV-uninfected (n = 95), cART experienced HIV-infected (n = 111), and cART-naive HIV-infected (n = 21) pregnant women. Immune activation was highest among HIV-infected/cART-naive women but decreased during pregnancy. Immune activation HIV-infected women who started cART during pregnancy was reduced but not to levels similar to those in HIV-uninfected women. The effects of elevated maternal immune activation in pregnancy on subsequent infant health and immunity remain to be determined.

Does antiretroviral therapy cause congenital malformations? A systematic review and meta-analysis.

OBJECTIVESThis meta-analysis investigated the risk of congenital anomalies among infants of human immunodeficiency virus-infected pregnant women who were exposed to antiretroviral therapy (ART).METHODSCohort studies, case-control studies, randomized controlled trials, and controlled clinical trials were reviewed by searching MEDLINE/PubMed, Embase, Web of Science, Scopus, AIDSLINE, CINAHL, Cochrane Library, and Google/Google Scholar. Methodological quality was assessed using the GRADE evaluation. A DerSimonian and Laird random-effects model was used. Subgroup analyses and meta-regression were used to investigate heterogeneity.RESULTSThe electronic searches yielded 765 items. After quality assessment and grading, 30 studies were suitable for metaanalysis. In total, 1,461 congenital anomalies were found among 53,186 births. Children born to women receiving combined antiretroviral therapy (cART) had an approximately 10% higher risk of developing congenital anomalies (relative risk [RR], 1.09; 95% confidence interval [CI], 1.04 to 1.14). A subgroup analysis found no significant difference in the risk of congenital anomalies between cART and efavirenz users. However, zidovudine and protease inhibitor (RR, 1.09; 95% CI, 1.00 to 1.19) users were found to have a 10% increased risk of congenital anomalies, and integrase inhibitor users had a 60% increase in risk (RR, 1.61; 95% CI, 1.60 to 2.43). The subgroup results should be interpreted cautiously because of the moderate heterogeneity (I2 =58%).CONCLUSIONSThe use of protease inhibitors, integrase inhibitors, zidovudine, and newer drugs should be carefully considered in pregnant women. Further studies are needed to address environmental, nutrition, and adherence factors related to ART. Establishing a congenital anomalies surveillance system is recommended.

High Stillbirth Rate among Human Immunodeficiency Virus-Infected Pregnant Women in West Bengal, India: a Retrospective Cohort Study.

Human immunodeficiency virus (HIV) infection in pregnancy may result in adverse obstetric outcomes, such as stillbirth. The present study aimed to compare the stillbirth rate (SBR) in HIV-infected pregnant women with that in the general population, observing the year-wise trends of HIV infection-associated SBR and identifying possible associated exposures. A retrospective cohort study was conducted through the analysis of secondary data from 314 integrated counseling and testing centers across the state of West Bengal, India, from 2012 to 2020. A total of 3,478 HIV-infected pregnant women were followed up, and year-wise SBR trends were compared with that among all pregnancies of the state as per the latest available Sample Registration System report in India. A linear regression analysis of the year-wise trend in SBR was performed. T-test of two means and the relative risk (RR with 95% confidence interval) was conducted to identify the associations between different exposures and stillbirth. The SBR was significantly higher (26.7/1,000) in HIV-infected pregnancies than in all pregnancies (5/1,000) and was significantly reduced after the initiation of antiretroviral treatment (RR = 0.09: 0.05-0.16). Spouse testing for HIV (surrogate marker for familial involvement) (RR = 0.35: 0.20- 0.61) and maternal literacy (RR = 0.62: 0.40-0.97) were also found to be significantly effective in preventing stillbirth.

Prevention of Mother-To-Child Transmission of HIV - China, 2011-2020.

IntroductionPrevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) is a global health focus in most parts of the world. The World Health Organization (WHO) launched the dual Elimination of Mother-to-Child Transmission (EMTCT) of HIV and syphilis initiative and released global guidance on criteria and processes for validation of the EMTCT in 2014. The purpose of this report was to analyze the key validation indicators of EMTCT of HIV in China from 2011 to 2020 and to provide relevant basis information for the implementation of EMTCT action in China.MethodsThe report described the coverage of maternal HIV screening and antiretroviral therapy usage for HIV infected pregnant women and their infants in China using the data from the national information systems of PMTCT of HIV, syphilis, and HBV management from 2011 to 2020.ResultsThe rates of maternal HIV testing during pregnancy (predelivery and at labor) and predelivery increased from 92.9% (8,730,161/9,398,781) and 53.7% (5,050,569/9,398,781) to 99.9% (11,964,026/11,982,321) and 97.5% (11,679,924/11,982,321), respectively. The MTCT rate reduced from 7.4% to 3.6% between 2011 and 2020.ConclusionsThe data from the surveillance systems revealed that there was a marked increase in the coverage of HIV screening of pregnant women and antiretrovirals drugs use for HIV infected pregnant women and their infants in China from 2011 to 2020.

Perinatal outcomes of twenty-five human immunodeficiency virus-infected pregnant women: Hacettepe University experience

Objective:To evaluate perinatal outcomes in human immunodeficiency virus (HIV) infected pregnant women in Turkey.Material and Methods:Maternal characteristics, pregnancy complications, laboratory findings including HIV load, CD4 cell count, CD4/CD8 ratio, neonatal features and final HIV status of the baby were retrospectively analyzed.Results:The sample included 26 singleton pregnancies, from 25 HIV-infected women. The ethnicities were Turkish (n=18), East European (n=4), Asian (n=2) and African (n=2). The majority (76.9%) was aware of their HIV status before becoming pregnant. Four cases (15.3%) were diagnosed during pregnancy and two (7.8%) at the onset of labor. The results for median HIV viral load, CD4 count, and CD4/CD8 ratio at birth were 20 copies/mL (0-34 587), 577/mm3 (115-977), and 0.7 (0.1-1.9), respectively. The HIV viral load rate was 5.5% in eighteen women taking anti-retroviral treatment. The rates of gestational diabetes mellitus, gestational hypertension, intrauterine growth restriction, and preterm delivery were 3.8%, 3.8%, 7.6%, and 8% (numbers are 1;1;2;2), respectively. The mean gestational week at birth was 38 weeks and mean birthweight is 2972±329 g. Two babies were congenitally infected with HIV (infection rate of 8.3%). There was one needle-related accident during surgery.Conclusion:Timely diagnosis of HIV infection during pregnancy is important for preventing mother to child transmission. HIV infected women may give birth to HIV negative babies with the help of a multidisciplinary team, composed of perinatology, infectious diseases, and pediatrics specialists.

An investigation of maternal anaemia among HIV infected pregnant women on antiretroviral treatment in Johannesburg, South Africa.

Introductionmaternal anaemia is a major public health problem in developing countries. Data suggests that anaemia contributes to the progression of Human Immunodeficiency Virus (HIV)-infection. The aim of this study was to investigate if pregnancy was an aggravating factor for anaemia among HIV-positive women on anti-retroviral treatment (ART).Methodswe analyzed data of all HIV-positive women aged 18-49 years receiving ART at Themba Lethu Clinic, Helen Joseph Hospital, Johannesburg, South Africa, from 1st April 2004- 30t hApril 2011. HIV-positive pregnant women were matched with non-pregnant women using the year of initiation of treatment. The outcome of interest ´anaemia´ was defined as “no anaemia”, “anaemia” and “moderate/severe anaemia”. We fitted an ordered logistic regression model to predict the likelihood of having severe/moderate anaemia versus no anaemia. We included pregnancy status as a predictor of the outcome and controlled the effect of other covariates in the analysis.Resultsthe study included 236 HIV positive patients, of which half (n=118, 50%) were pregnant. At baseline, about (n=143, 60%) of patients were anaemic. The proportion of pregnant women classified as anaemic (anaemia, moderate/severe) differed significantly (p=0.02) from that of non-pregnant women. The following characteristics were significantly associated with anaemia at baseline: Body mass index (BMI) category (p=0.01); World Health Organization (WHO) stage (p=0.001) and CD4 count (p=0.001). Seven months after initiation of treatment, the proportion of HIV positive women with anaemia decreased significantly.Conclusionanaemia is a significant risk factor for untoward health outcomes, especially among HIV-positive pregnant women. Early ART access might result in a significant decrease in anaemia in pregnancy.

Screening for HIV Infection in Pregnant Women: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

(Abstracted from JAMA 2019;321(23):2349–2360) Human immunodeficiency virus (HIV) can be transmitted from mother to child (MTCT) during pregnancy and the postpartum period. The number of perinatal HIV infections in the United States declined from 1985 to 2001 after routine prenatal screening was implemented across the country, along with the use of effective therapies for preventing MTCT.

Prevalence of Hepatitis B and C among HIV Infected Pregnant Women Attending Care and Treatment at National Institute for Pharmaceutical Research and Development (NIPRD), Abuja, Nigeria

Introduction: Viral Hepatitis and Human Immunodeficiency Virus (HIV) are most common top ranking leading causes of infectious diseases and deaths worldwide. If these infections, remain unidentified and untreated among HIV infected pregnant women, children born to these pregnant women are at high risk of these viral hepatitis infections.&#x0D; Aims: The aim of the study was to determine the sero-prevalence of HBV and HCV among HIV infected pregnant women in Abuja, Nigeria.&#x0D; Methodology: A cross sectional study among 330 HIV infected pregnant women commencing antiretroviral therapy (ART) at National Institute for Pharmaceutical Research and Development (NIPRD), Abuja, Nigeria were studied. The women were screened for the presence of HBV and HCV antibodies. A pre-tested questionnaire was used to obtain socio-demographic data prior to recruitment/enrollment. Data were analyzed using statistical product and service solutions (SPSS) (version 20.0).&#x0D; Results: Out of the 330 HIV infected pregnant women, 90 (27.3%) were HBV positive, while 5 (1.5%) were HCV positive (p = 0.42). The highest prevalence was observed among the age group of 20 – 29. However, none of the patients tested positive for both HBV and HCV.&#x0D; Conclusion: The findings of this study indicated that infection with viral hepatitis is common and of public health concern. Therefore, concerted efforts should be put in place to mitigate the epidemics.

Sexual Behaviors of Human Immunodeficiency Virus-Infected Pregnant Women and Factors Associated With Sexually Transmitted Infection in South Africa.

Sexual behaviors in human immunodeficiency virus (HIV)-infected pregnant women in South Africa are not well understood. Human immunodeficiency virus-infected pregnant women were recruited into a prospective cohort at first antenatal care visit. Sociodemographic information and self-collected vulvovaginal swab samples were collected from participants. Vulvovaginal swab samples were tested for Chlamydia trachomatis, Neisseria gonorrhoea, and Trichomonas vaginalis using GeneXpert. We investigated sexual behaviors, alcohol use, factors associated with condomless sex during pregnancy, and prevalent sexually transmitted infection (STI) among our cohort. We report descriptive, univariate and multivariable logistic regression results of sexual behaviors and alcohol use, factors associated with condomless sex at last sex, and having any STI during pregnancy adjusting for a priori confounders. We recruited and enrolled 430 HIV-infected pregnant women. Median age was 30 years; median gestational age was 20 weeks. Eighty-nine percent of women reported sex during pregnancy. At last sex, 68% reported condomless sex; 18% reported having more than 1 sex partner in the past 12 months. Adjusting for age, income and relationship status, condom use at last sex was associated with prior knowledge of HIV status (adjusted odds ratio [aOR], 2.46; 95% confidence interval [CI], 1.54-3.92) and being in a concordant HIV-positive (aOR, 3.17; 95% CI, 1.84-5.50), or serodiscordant relationship (aOR, 6.50; 95% CI, 3.59-11.80). The prevalence of any STI was 41% (95% CI, 36%-45%). Adjusting for mothers' age and employment, odds of having an STI increased if the woman reported alcohol use during pregnancy (aOR, 1.96; 95% CI, 1.06-3.64) or if the father of the child was a non-cohabiting or casual partner (aOR, 1.42; 95% CI, 0.97-2.03). Almost all HIV-infected pregnant women were sexually active during pregnancy and most women reported condomless sex at last sex. Condom use was associated with knowledge of serostatus and/or partner's serostatus before first antenatal care visit. Factors associated with having STIs included: alcohol use during pregnancy and father of child being a non-cohabiting partner.

ACTUAL ISSUES IN HIV INFECTION AND PREVENTION OF PERINATAL HIV TRANSMISSION IN THE SOUTH OF RUSSIA

One of the serious negative consequences of the HIV infection epidemic is the involvement of women of reproductive age and children into the epidemic process. The problem of vertical HIV infection transmission does not lose its relevance and causes the need for continuous monitoring of measures to prevent the transmission of HIV from mother to child. The aim of the study is to evaluate the effectiveness of a set of measures to prevent the transmission of HIV infection from mother to child in the South of Russia.Materials and methods. The common methods of variation statistics were used in the work to analyze the data from the reporting forms of monitoring by Rospotrebnadzor «Imformation on measures for the prevention of HIV infection, hepatitis B and C, detection and treatment of HIV patients» and federal reporting forms N 61 «Information on contingents of patients with a disease caused by a human immunodeficiency virus (HIV)» for 2016 and 2017, presented by the territorial Centers for Prevention and Control of AIDS of 15 RF subjects of the Southern Federal District and the North Caucasus Federal District.Results. In 2017, compared to 2016, the decrease in the number of births in HIV-positive women was traced on the territory of the South of Russia. In 2017, target levels of mother-child coverage with chemoprevention of mother-to-child transmission of HIV during pregnancy (over 92%) and during childbirth (more than 93,5%) were achieved in the Southern Federal District and the North Caucasus Federal District. A high proportion of women with a detectable level of HIV replication before birth was revealed.Conclusion. The implementation of the recommended by standards preventive measures and the provision of antiretroviral drugs allowed to significantly increase the coverage of HIV infected pregnant women and their newborns with antiretroviral prophylactic treatment by 2018 which prevented HIV infection transmission from mothers to 8840 children. The problems that prevent the implementation of the full range of measures for the prevention of the vertical transmission of HIV in the South of Russia are identified and approaches for their solution are suggested.

Pre-eclampsia: the role of highly active antiretroviral therapy and immune markers.

This review highlights the role immune cells and markers such as natural killer (NK) cells, cytokines and human leukocyte antigen (HLA-G) play in predisposing HIV-infected women who are on HAART to develop PE, thus contributing to a better understanding and early diagnosis of PE with a subsequent reduction in maternal foetal and neonatal deaths. Pregnant women infected with the Human Immunodeficiency Virus (HIV) have a 25% risk of mother to child transmission. This risk, however, decreases to 2% if the women is on treatment. Highly active antiretroviral therapy (HAART) is the recommended treatment for both pregnant and non-pregnant women infected with HIV. Treatment with HAART is reported to potentiate predisposition to the development of hypertensive disorders of pregnancy such as pre-eclampsia (PE). Pre-eclampsia accounts for 7-10% of abnormal pregnancies worldwide. Studies demonstrate that pregnant women with HIV have PE at lower frequencies than uninfected women, however, the converse is observed upon HAART initiation. HIV-infected women on HAART exhibit a greater tendency to develop PE, emanating from immune reconstitution induced by HAART. There is paucity of information as to the pathogenesis of PE upon HAART initiation and there are, therefore, controversial data as to whether HAART predisposes women to a lower, equal or higher risk of PE development compared to the general population, further investigations on the impact of HIV infection and HAART on the immune response and rate of PE development in HIV infected pregnant women are urgently needed.

Intestinal Barrier Dysfunction and Microbial Translocation in Human Immunodeficiency Virus-Infected Pregnant Women Are Associated With Preterm Birth.

Preterm birth (PTB) rates are high in human immunodeficiency virus (HIV)-infected populations, even when on treatment. Still, only a subset of all births in HIV-infected pregnant women result in PTB, suggesting that risk factors other than HIV infection itself are also important. Inflammation is a known risk factor in uninfected populations, but its role in HIV-infected population have not been studied; in addition, the immune pathways involved are not clear and noninvasive immune markers with predictive value are lacking. Our objective was to determine the association of select markers of inflammation with PTB in HIV-1-infected pregnant women. Within a randomized trial of pregnant women receiving nevirapine (Six-Week Extended-Dose Nevirapine [SWEN] trial), we nested a case-control study (n = 107; 26 cases, 81 controls) to determine the association of maternal inflammation with PTB. Cases were defined as PTB (<37 weeks' gestational age). We assessed inflammation by measuring plasma levels of markers of general inflammation (C-reactive protein [CRP]), intestinal barrier dysfunction (intestinal fatty acid binding protein [I-FABP]), and microbial translocation/monocyte activation (soluble CD14 [sCD14] and CD163 [sCD163]). Multivariable logistic regression was used to determine the odds of PTB per log2 increase of each marker. In multivariable models, there was increased odds of PTB per unit increase of log2 sCD14 (adjusted odds ratio [aOR], 2.45; 95% confidence interval [CI], 1.24-4.86), log2 sCD163 (aOR, 3.87; 95% CI, 1.43-10.49), and log2 I-FABP (aOR, 2.28; 95% CI, 1.18-4.41) but not log2 CRP (aOR, 0.72; 95% CI, .48-1.09). Our results show that select immune markers can identify women at higher risk for PTB in HIV-1-infected populations and suggest that modulating gut barrier integrity and microbial translocation may affect PTB.

The prevalence and risk factors for Trichomonas vaginalis infection amongst human immunodeficiency virus-infected pregnant women attending the antenatal clinics of a university teaching hospital in Lagos, South-Western, Nigeria.

Trichomonas vaginalis infection is the most prevalent non-viral sexually transmitted infection worldwide. Interactions between this infection and human immunodeficiency virus (HIV) may cause adverse pregnancy outcomes such as preterm labour, premature rupture of membranes, chorioamnionitis, low birth weight and post-abortal sepsis. This study was aimed to determine the prevalence and risk factors of T. vaginalis infection amongst HIV-positive pregnant women attending antenatal care at the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria. This was an analytical cross-sectional study in which 320 eligible participants which included 160 HIV-positive (case group) and 160 HIV-negative (control group) pregnant women were recruited at the antenatal clinic of LUTH. A structured pro forma was used to collect data from consenting participants after which high vaginal swabs were collected, processed and examined for T. vaginalis. The association between categorical variables was tested using the Chi-square test and Fisher's exact test where applicable. All significances were reported at P < 0.05. The prevalence of T. vaginalis infection amongst HIV-positive and HIV-negative pregnant women were 10% and 8.1%, respectively (P = 0.559). Significant risk factors for T. vaginalis infection in the HIV-positive pregnant women were early coitarche (P < 0.005) and multiple lifetime sexual partners (P = 0.021). There was no relationship between the T. vaginalis infection and the immunological markers of HIV infection. While this study does not provide grounds for universal screening of pregnant women for T. vaginalis infection as a tool of reducing HIV acquisition, especially in pregnancy, campaign to create better sexual health awareness should be commenced as a way to contributing to the reduction in T. vaginalis infection during pregnancy and perinatal transmission of HIV.

Poor Obstetric and Infant Outcomes in Human Immunodeficiency Virus-Infected Pregnant Women With Tuberculosis in South Africa: The Tshepiso Study.

Before the wide availability of antiretroviral therapy (ART), tuberculosis and human immunodeficiency virus (HIV) disease among pregnant women resulted in poor maternal and neonatal outcomes, including high rates of mother-to-child transmission of both HIV and tuberculosis. We aimed to describe the impact of tuberculosis among HIV-infected mothers on obstetric and infant outcomes in a population with access to ART. In this prospective cohort study, we followed up HIV-infected pregnant women with or without tuberculosis disease from January 2011 through January 2014 in Soweto, South Africa. Two controls were enrolled for each case patient, matched by enrollment time, maternal age, gestational age, and planned delivery clinic and followed up for 12 months after delivery. We recruited 80 case patients and 155 controls, resulting in 224 live-born infants. Infants of mothers with HIV infection and tuberculosis disease had a higher risk of low birth weight (20.8% vs 10.7%; P = .04), prolonged hospitalization at birth (51% vs 16%; P < .001), infant death (68 vs 7 deaths per 1000 births; P < .001), and tuberculosis disease (12% vs 0%; P < .001) despite appropriate maternal therapy and infant tuberculosis preventive therapy. HIV transmission was higher among these infants (4.1% vs 1.3%; P = .20), though this difference was not statistically significant. Obstetric outcomes in coinfected women were also poorer with higher risks of maternal hospitalization (25% vs 11%; P = .005) and preeclampsia (5.5% vs 0.7%; P = .03). Tuberculosis in HIV coinfected pregnant women remains a significant threat to the health of both mothers and infants. Improving tuberculosis prevention and early diagnosis among pregnant women is critical.

Elevated Levels of Estradiol in Human Immunodeficiency Virus-Infected Pregnant Women on Protease Inhibitor-Based Regimens.

Human immunodeficiency virus (HIV)-infected pregnant women on protease inhibitor (PI)-based combination antiretroviral therapy (cART) have a greater risk for adverse birth outcomes, and an association with steroid hormone levels has been implicated. The objective of this study was to investigate the association between PI-cART and estradiol levels in pregnancy. Fifty-five HIV-infected and 49 HIV-uninfected Canadian pregnant women were followed prospectively throughout gestation. All HIV-infected women were on a PI-based cART regimen. Maternal plasma samples were collected at 12-18 weeks, 24-28 weeks, 34-38 weeks, at delivery, and from the cord. Birth outcomes were recorded. Levels of estradiol, dehydroepiandrosterone sulfate (DHEAS), sex hormone-binding globulin (SHBG), cortisol, and adrenocorticotropic hormone (ACTH) were quantified by enzyme-linked immunosorbent assay. (median [interquartile range] for cord estradiol: 23.9 ng/mL [16.4-36.4] for HIV-infected exposed to PI-cART and 15.7 ng/mL [12.2-21.2] for HIV-negative; P = .0025). HIV-infected women had higher DHEAS levels in cord plasma that correlated with cord and maternal delivery estradiol levels. Cortisol and ACTH levels did not differ between groups. In the HIV-infected women, cord estradiol levels correlated negatively with birth weight centile (r = -0.47, P = .0016). Our data suggest that PI-cART exposure in pregnancy is associated with elevated levels of estradiol, likely driven by higher fetal DHEAS production. Cord estradiol levels were inversely correlated with birth weight centile in infants born to PI-cART-exposed women, suggesting that fetal exposure to high estradiol levels may be contributing to cART-associated fetal growth restriction.

High prevalence of asymptomatic sexually transmitted infections among human immunodeficiency virus-infected pregnant women in a low-income South African community.

There is a lack of evidence on the burden of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) among HIV-infected pregnant women in South Africa. We conducted a cross-sectional analysis of HIV-infected pregnant women in two healthcare facilities in a South African township to determine the prevalence of CT, NG and TV. HIV-infected pregnant women were recruited during the first antenatal care visit for their current pregnancy and requested to self-collect vulvovaginal swab specimens. Specimens were tested for CT, NG and TV using the Xpert® assay (Cepheid, Sunnyvale, CA). Of 247 tested for CT, NG and TV, 47.8% tested positive for at least one organism; CT = 36.8%, TV = 23.9%, NG = 6.9%. Forty three (17.4%) had multiple infections, of which 42 included CT as one of the infecting organisms. Of the 118 participants who tested positive for at least one sexually transmitted infection (STI), 23.7% reported STI-like symptoms. Among women who tested positive for CT, 29.7% reported symptoms while 47.1 and 27.1% of those who tested positive for NG and TV, respectively, reported symptoms. The high STI prevalence coupled with the low symptom prevalence among infected individuals justifies the use of diagnostic screening approaches rather than syndromic management of STIs in this setting.

Birth Weight and Preterm Delivery Outcomes of Perinatally vs Nonperinatally Human Immunodeficiency Virus-Infected Pregnant Women in the United States: Results From the PHACS SMARTT Study and IMPAACT P1025 Protocol.

Pregnancy outcomes of perinatally human immunodeficiency virus-infected women (PHIV) are poorly defined. We compared preterm delivery and birth weight (BW) outcomes (low BW [LBW], <2500 g), small-for-gestational-age [SGA], and BW z scores [BWZ]) in HIV-exposed uninfected infants of PHIV vs nonperinatally HIV-infected (NPHIV) pregnant women in the Pediatric HIV/AIDS Cohort Study Surveillance Monitoring of ART Toxicities or International Maternal Pediatric Adolescent AIDS Clinical Trials P1025 studies. Mixed effects models and log binomial models were used to assess the association of maternal PHIV status with infant outcomes. Age-stratified analyses were performed. From 1998 to 2013, 2270 HIV-infected pregnant women delivered 2692 newborns (270 born to PHIV and 2422 to NPHIV women). PHIV women were younger, (mean age 21 vs 25 years, P < .01) and more likely to have a pregnancy CD4 count <200 cells/mm3 (19% vs 11%, P = .01). No associations between maternal PHIV status and preterm delivery, SGA, or LBW were observed. After adjustment, BWZ was 0.12 lower in infants of PHIV vs NPHIV women (adjusted mean, -0.45 vs -0.33; P = .04). Among women aged 23-30 years (n = 1770), maternal PHIV was associated with LBW (aRR = 1.74; 95% confidence interval, 1.18, 2.58; P < .01). The overall lack of association between maternal PHIV status and preterm delivery or infant BW outcomes is reassuring. The higher rates of LBW observed in PHIV women aged 23-30 years warrants further mechanism-based investigations as this is a rapidly growing and aging population worldwide.
