Incident pregnancy and pregnancy outcomes among HIV-infected women in Uganda and Zimbabwe

Pregnancy incidence, outcomes and associated factors in a cohort of women living with HIV/AIDS in Rio de Janeiro, Brazil, 1996-2016

The aim of this research was to analyze pregnancy incidence and associated factors in a cohort of 753 women living with HIV/AIDS (WLWHA) in Rio de Janeiro, Brazil, from 1996 to 2016. Women aged 18-49 years who were not on menopause (surgical or natural) and did not have a tubal ligation were eligible for the study. Data were collected by medical professionals during initial and follow-up visits. Person-time pregnancy incidence rates were calculated throughout the follow-up period. Pregnancy incidence-associated factors were investigated by univariate and multiple analyzes, using an extension of the Cox survival model. Follow-up visits recorded 194 pregnancies, with an incidence rate of 4.01/100 person-years (95% CI: 3.47; 4.60). A higher pregnancy incidence was associated with CD4 nadir ≥ 350 cells/mm³, use of an antiretroviral regimen not containing Efavirenz, and prior teenage pregnancy. In turn, women with a viral load ≥ 50 copies/mL, age ≥ 35 years old, with two or more children and using a highly effective contraceptive method showed a lower incidence. Results showed a significant reduction in pregnancy incidence after 2006, a significant reduction in female sterilization from 1996 to 2016, and a high rate of cesarean sections. The association found between pregnancy incidence and the use of contraceptive methods and virological control markers suggests a good integration between HIV/AIDS and reproductive health services. The high rate of cesarean section delivery indicates the need to improve childbirth care.

Fertility trends by HIV status in a health and demographic surveillance study in Magu District, Tanzania, 1994-2018

BACKGROUND

Sub-Saharan Africa (SSA) has the highest fertility rates and highest HIV disease burden globally. However, it is not clear how the rapid expansion of anti-retroviral therapy (ART) for HIV has impacted the fertility gap between HIV-infected and uninfected women. We used data from a Health and Demographic Surveillance System (HDSS) in north-western Tanzania to explore trends in fertility rates and the relationship between HIV and fertility over the 25-year period.

METHODS

From 1994 to 2018, births and population denominators from the HDSS population were used to obtain age-specific fertility rates (ASFRs) and total fertility rates (TFRs). HIV status was extracted from eight rounds of epidemiologic serological surveillances (1994-2017). Fertility rates by HIV status and in different levels of ART availability were compared over time. Independent risk factors for fertility changes were examined using Cox proportional hazard models.

RESULTS

There were 24,662 births from 36,814 women (15-49) who contributed a total of 145,452.5 Person-Years of follow-ups. The TFR declined from 6.5 births per woman in 1994-1998 to 4.3 births per woman in 2014-2018. The number of births per woman was 40% lower in women living with HIV than in HIV-uninfected women (4.4 vs. 6.7), although this difference narrowed over time. The fertility rate in HIV-uninfected women was 36% lower in 2013-2018 than in 1994-1998(age-adjusted HR = 0.641; 95% CI 0.613-0.673). In contrast, the fertility rate in women living with HIV was relatively unchanged over the same follow up period (age-adjusted HR = 1.099; 95% CI 0.870-1.387).

CONCLUSIONS

There was a notable fertility decline among women in the study area from 1994 to 2018. Fertility remained lower in women living with HIV than in HIV-uninfected women, but the difference continued to narrow over time. These results highlight the need for more research into fertility changes, fertility desire and family planning use in Tanzanian rural communities.

Effect of optimal antenatal care on maternal and perinatal health in Ethiopia

INTRODUCTION

Receiving at least four antenatal care (ANC) visits have paramount importance on the health of mothers and perinates. In Ethiopia, several studies were conducted on ANC service utilization; however, limited studies quantified the effect of care on maternal and perinate health. In response to this gap, this study is conducted to quantify the effect of optimal ANC care (≥4 visits) on maternal and perinatal health among women who received optimal care in comparison to women who did not receive optimal care.

METHODS

The study utilized the Ethiopian perinatal death surveillance and response (PDSR) system dataset. A total of 3,814 reviewed perinatal deaths were included in the study. Considering the nature of the data, preferential within propensity score matching (PWPSM) was performed to determine the effect of optimal ANC care on maternal and perinatal health. The effect of optimal care was reported using average treatment effects of the treated [ATT].

RESULT

The result revealed that optimal ANC care had a positive effect on reducing perinatal death, due to respiratory and cardiovascular disorders, [ATT = -0.015, 95%CI (-0.029 to -0.001)] and extending intrauterine life by one week [ATT = 1.277, 95%CI: (0.563-1.991)]. While it's effect on maternal health includes, avoiding the risk of having uterine rupture [ATT = -0.012, 95%CI: (-0.018 to -0.005)], improving the utilization of operative vaginal delivery (OVD) [ATT = 0.032, 95%CI: (0.001-0.062)] and avoiding delay to decide to seek care [ATT = -0.187, 95%CI: (-0.354 to -0.021)].

CONCLUSION

Obtaining optimal ANC care has a positive effect on both maternal and perinatal health. Therefore, policies and interventions geared towards improving the coverage and quality of ANC services should be the top priority to maximize the benefit of the care.

Adverse pregnancy outcomes among pregnant women living with HIV in Hubei province, China: prevalence and risk factors

Mother-to-child transmission of Human Immunodeficiency Virus (HIV) has been greatly reduced with the advance of intervention technology. However, adverse pregnancy outcomes (APOs) are still common, and little is known about the driving forces of APOs among pregnant women living with HIV in China. Between January 2004 and December 2020, a total of 638 pregnancies among pregnant women living with HIV were enrolled in this study, 84 (13.2%) pregnancies with 87 APOs were reported. Preterm birth (3.8%), ectopic pregnancy (3.4%), spontaneous abortion (2.0%), and embryo arrest (1.7%) were the most common APOs in pregnant women living with HIV. Exposure to antiretroviral drugs (ARVs) during the first trimester (RR =  4.077, 95% CI: 0.521, 1.484, P<0.001) and the first CD4+ T lymphocyte count (CD4 count)≤ 350/μl (RR =  2.227, 95% CI: 0.063, 0.991, P = 0.026) were risk factors of APOs. The age≤ 30 years (RR =  -2.513, 95% CI: -1.067, -0.132, P = 0.012) was associated with the decreasing of APOs. Encouraging people to initiate combination antiretroviral therapy and reach a high CD4 count level before pregnancy would be helpful to prevent APOs. Pregnant women exposed to ARVs in the first trimester needed more attention for APOs.

Interventions to reduce preterm birth and stillbirth, and improve outcomes for babies born preterm in low- and middle-income countries: A systematic review

BACKGROUND

Reducing preterm birth and stillbirth and improving outcomes for babies born too soon is essential to reduce under-5 mortality globally. In the context of a rapidly evolving evidence base and problems with extrapolating efficacy data from high- to low-income settings, an assessment of the evidence for maternal and newborn interventions specific to low- and middle-income countries (LMICs) is required.

METHODS

A systematic review of the literature was done. We included all studies performed in LMICs since the Every Newborn Action Plan, between 2013 - 2018, which reported on interventions where the outcome assessed was reduction in preterm birth or stillbirth incidence and/or a reduction in preterm infant neonatal mortality. Evidence was categorised according to maternal or neonatal intervention groups and a narrative synthesis conducted.

RESULTS

179 studies (147 primary evidence studies and 32 systematic reviews) were identified in 82 LMICs. 81 studies reported on maternal interventions and 98 reported on neonatal interventions. Interventions in pregnant mothers which resulted in significant reductions in preterm birth and stillbirth were (i) multiple micronutrient supplementation and (ii) enhanced quality of antenatal care. Routine antenatal ultrasound in LMICs increased identification of fetal antenatal conditions but did not reduce stillbirth or preterm birth due to the absence of services to manage these diagnoses. Interventions in pre-term neonates which improved their survival included (i) feeding support including probiotics and (ii) thermal regulation. Improved provision of neonatal resuscitation did not improve pre-term mortality rates, highlighting the importance of post-resuscitation care. Community mobilisation, for example through community education packages, was found to be an effective way of delivering interventions.

CONCLUSIONS

Evidence supports the implementation of several low-cost interventions with the potential to deliver reductions in preterm birth and stillbirth and improve outcomes for preterm babies in LMICs. These, however, must be complemented by overall health systems strengthening to be effective. Quality improvement methodology and learning health systems approaches can provide important means of understanding and tackling implementation challenges within local contexts. Further pragmatic efficacy trials of interventions in LMICs are essential, particularly for interventions not previously tested in these contexts.

Treatment outcomes of pregnant women with drug-resistant tuberculosis in Uganda: A retrospective review of 18 cases

BACKGROUND

There is a dearth of reports on drug-resistant tuberculosis (DRTB) treatment outcomes among pregnant women in tuberculosis (TB)/HIV high-burdened countries. We report treatment outcomes of 18 pregnant women with DRTB in Uganda.

METHODS

We reviewed charts of individuals who received DRTB treatment in Uganda across 16 DRTB treatment sites. We included all women who were pregnant during DRTB treatment and had a treatment outcome documented between 2013 and 2019.

RESULTS

There were 18 pregnant women with a mean age (standard deviation (SD)) of 27.5 (5.2) years, of whom 8 (44.4%) were HIV co-infected. Among these women, 12 (66.7%) had primary DRTB and 8 (44.4%) had multidrug-resistant TB. Levofloxacin (Lfx), Pyrazinamide, Cycloserine and Kanamycin (Kn) were the most (>78%) used drugs in the treatment regimen and the mean (SD) treatment duration was 17.6 (7.5) months. Elevated liver enzymes (81.8%, n = 11) and hearing loss (33.3%, n = 15) were the most frequently encountered drug adverse events. Treatment success was observed among 15 (83.3%) patients, 2 (11.1%) patients were lost to follow up and 1 (5.6%) patient died.

CONCLUSION

The treatment success among pregnant women with DRTB in Uganda was high despite a high prevalence of HIV co-infection.

Pregnancy in women diagnosed with HIV on antiretroviral therapy in Ethiopia: a retrospective cohort study

Introduction

due to increasing coverage of antiretroviral therapy (ART), more women living with HIV have improved health condition which also increases their chances of getting pregnant. However, the knowledge about pregnancy among women receiving ART in resource-constrained settings, like Ethiopia, is limited. The aim was to assess factors associated with pregnancy among women living with HIV in Ethiopia.

Methods

a retrospective cohort study from 2005 through 2013 including a total of 809 women aged 15-49 years on ART was used. The study was conducted in eight hospitals and health centers in two regions of Ethiopia. The data was collected between March and June of 2014 from patients´ pre-ART and ART registers by trained nurses, assisted by data entry clerks and supervised by senior physicians. Kaplan-Meier survival analysis and Cox regression analysis were used to examine the probability of becoming pregnant. Factors associated with pregnancy were presented with hazard ratios with 95% Confidence Interval (CI).

Results

a total of 809 women were included in this analysis, their median age was 27 years, 90% were urban residents and 40.6% were married. Four hundred eighty three (60.6%) were in WHO stage III at initiation of ART. The median CD4 count was 162.5 cell/μl at initiation of ART. Eighty-one women became pregnant during 3069 person-years of observation. The overall incidence of pregnancy was 26.4 pregnancies per 1000 person-years of observation. Women under the age of 24, those in less advanced disease stage, women with no education and those with college education had higher rates of pregnancy.

Conclusion

the results highlight that younger women, those in less advanced disease stage, either uneducated or highly educated ones have higher probability of becoming pregnant during HIV treatment. This suggests the need for integrating reproductive health services into HIV care services to meet the needs of women on ART.

Pregnancy outcomes and effects of antiretroviral drugs in HIV-positive pregnant women: a systematic review

Aim: Despite the clear morbidity, mortality and vertical transmission rates in women infected with HIV, there is still controversy surrounding the relationship between maternal infection and adverse neonatal outcomes. Antiretroviral therapy during pregnancy is considered the main and most effective method for reducing the vertical transmission of infection. However, there is no consensus over potential associations between antiretroviral therapy and adverse pregnancy outcomes. This systematic review focuses on the effects of antiretroviral drugs on pregnancy outcomes in HIV-positive women. Methods: After searching MEDLINE, the Cochrane Database of Systematic Reviews, the ISI Web of Sciences and EMBASE, 570 potentially eligible papers were identified. Only 32 papers were selected based on the inclusion criteria. Results: The most prevalent adverse pregnancy outcomes were low birth weight, preterm birth and stillbirth. Conclusion: Considering the higher prevalence of adverse pregnancy outcomes in HIV-infected women, HIV screening methods should be administered in all pregnant women. Appropriate treatment modalities should also be selected to minimize adverse pregnancy outcomes.

A Longitudinal Assessment of Cervical Inflammation and Immunity Associated with HIV-1 Infection, Hormonal Contraception, and Pregnancy

Hormonal contraception (HC), particularly injectable depot-medroxyprogesterone acetate (DMPA), has been associated with increased HIV acquisition and higher levels of cervical regulated upon activation, normal T-cell expressed, and secreted (RANTES), also associated with HIV seroconversion. Longitudinal changes in cervical immunity associated with DMPA and combined oral contraceptives (COCs) have not been studied. Cervical samples from 216 HIV seroconverters in Uganda and Zimbabwe with matched samples from 727 HIV-uninfected controls were collected at two quarterly visits before (t - 2, t - 1), at (t0), and two visits following (t + 1, t + 2) HIV seroconversion and corresponding visits for HIV-negative controls. We measured 10 biomarkers of inflammation and immunity and used generalized linear models to estimate and compare biomarker levels across HIV status, contraceptive, and pregnancy groups. Biomarkers remained relatively stable across visits for controls, while in HIV-infected women cervical immunity started to change before seroconversion with RANTES and BD-2 increased and secretory leukocyte protease inhibitor (SLPI) decreased at t - 1 and continued to change at t0 with ICAM-1 up and IL-8 down and with more biomarkers after seroconversion (IL-1β, IL-6, MIP-3α, VEGF, and IL-1RA down and IL-1RA:IL-1β ratio up). In multivariable analyses, seroconverters had higher BD-2 at t - 1, higher RANTES and lower SLPI from t - 1 through t + 2, and lower IL-8 and IL-1RA at and/or after seroconversion compared to nonseroconverters. Compared to non-HC users, DMPA users had higher RANTES at all visits and lower BD-2 at t - 2 through t0, while COC users and pregnant women had higher IL-8 and SLPI at all visits; COC users also had lower BD-2 preseroconversion; pregnant women had lower RANTES at t0 - t + 2. Longitudinal patterns of cervical immunity differ between HIV seroconverters and HIV-negative women; seroconverters demonstrate increased RANTES and decreased SLPI starting before and continuing postseroconversion. Furthermore, these patterns are differentially regulated by DMPA, COC, and pregnancy.

Prenatal diagnosis, care and management in Africa: bibliometric analysis

Prenatal diagnosis, care and management are involved in mortality and morbidity of every country. A high prevalence is estimated in Africa. We use bibliometrics and mapping tools to explore the area studies and countries involved in scientific research on prenatal diagnosis, care and management in Africa. We used two databases: Web of Science and Pubmed. We extracted sets of data as publication years, organizations, funding agencies, countries from Web of Science core collection database and Medical Subject Headings from Pubmed database. We mapped the data using VOSviewer. We performed keyword analysis. We accessed 463 articles published between 1956 and 2015 in Web of Science Core collection Database and 3372 from Pubmed database. The majority of which were after 2004. The main countries involved in research on prenatal field in Africa were the USA, the United Kingdom, France and South Africa. Two main keywords are relevant: fetal alcohol syndrome and HIV. Prenatal diagnosis, care and management are leaded by South Africa. Some new countries are merging such as Rwanda. The main fields are fetal alcohol syndrome and HIV. It is funded by NIH but also Cape Town University.

Impact of ART on the fertility of HIV-positive women in sub-Saharan Africa

OBJECTIVE

Understanding the fertility of HIV-positive women is critical to estimating HIV epidemic trends from surveillance data and to planning resource needs and coverage of prevention of mother-to-child transmission services in sub-Saharan Africa. In the light of the considerable scale-up in antiretroviral therapy (ART) coverage over the last decade, we conducted a systematic review of the impact of ART on the fertility outcomes of HIV-positive women.

METHODS

We searched Medline, Embase, Popline, PubMed and African Index Medicus. Studies were included if they were conducted in sub-Saharan Africa and provided estimates of fertility outcomes (live births or pregnancies) among women on ART relative to a comparison group.

RESULTS

Of 2070 unique references, 18 published papers met all eligibility criteria. Comparisons fell into four categories: fertility of HIV-positive women relative to HIV-negative women; fertility of HIV-positive women on ART compared to those not yet on ART; fertility differences by duration on ART; and temporal trends in fertility among HIV-positive women. Evidence indicates that fertility increases after approximately the first year on ART and that while the fertility deficit of HIV-positive women is shrinking, their fertility remains below that of HIV-negative women. These findings, however, were based on limited data mostly during the period 2005-2010 when ART scaled up.

CONCLUSIONS

Existing data are insufficient to characterise how ART has affected the fertility of HIV-positive women in sub-Saharan Africa. Improving evidence about fertility among women on ART is an urgent priority for planning HIV resource needs and understanding HIV epidemic trends. Alternative data sources such as antenatal clinic data, general population cohorts and population-based surveys can be harnessed to understand the issue.
