Increasing incidence of pregnancy among women receiving HIV care and treatment at a large urban facility in western Uganda

Effect of predictors on incidence rate of pregnancy among reproductive age women on antiretroviral therapy at public hospitals of Jigjiga and Harar Towns, Eastern Ethiopia: a retrospective cohort study

BACKGROUND

Globally, Human Immunodeficiency Virus (HIV) is the leading cause of death in women of reproductive age and accountable for a quarter of deaths during pregnancy in sub-Saharan Africa including Ethiopia. Introduction of antiretroviral therapy to women living with HIV highly improves lifestyle and the desire to have children. A comprehensive understanding of baseline predictors of pregnancy among women receiving ART essential to reduces unintended pregnancies, appropriate care, and preventing transmission from mother to child.

OBJECTIVE

To determine the effect of baseline predictors on incidence rate of pregnancy among reproductive age women on antiretroviral therapy at public hospitals of Jigjiga and Harar town, Eastern Ethiopia from February 15 to march 15, 2020.

METHODS

Retrospective cohort study was conducted on randomly selected 420 HIV-infected women using data recorded from September 11, 2014, to September 10, 2019 in Jigjiga and Harar town in Eastern Ethiopia. Simple random sampling was used to select study subjects from each hospital. Data were entered to Epi data version 3.2 and exported to Stata version 14.2 for analysis. Kaplan-Meier failure, and Cox proportional hazards model were used to estimate the incidence, and to identify predictors of pregnancy respectively. Variables which were significant (P value < 0.05) in the multivariate analysis were considered independent predictors of pregnancy.

RESULTS

The overall incidence rate of pregnancy was 9.1 per 100 person-years (95% CI 7.19, 11.76). Being unadvanced HIV disease stage (AHR: 2.50; 95% CI 1.46, 4.19), having less than two children (AHR: 2.93; 95% CI 1.59, 5.40), and disclosed HIV status (AHR: 2.25; 95% CI 1.34, 3.79) were independent predictors of pregnancy.

CONCLUSION

The incidence rate of pregnancy among reproductive age women on ART was found to be considerable. Being unadvanced HIV disease stage, having less than two children, and disclosed HIV status were independent predictors of pregnancy. Thus, tailoring counseling have to be designed to enhance better pregnancy planning and consecutive health outcomes.

No association between fertility desire and HIV infections among men and women: Findings from community-based studies before and after implementation of an early antiretroviral therapy (ART) initiation program in the rural district of North-western Tanzania

Background: Fertility is associated with the desire to have children. The impacts of HIV and antiretroviral therapy (ART) on fertility are well known, but their impacts on the desire for children are less well known in Tanzania. We used data from two studies carried out at different periods of ART coverage in rural Tanzania to explore the relationship between HIV infection and fertility desires in men and women. Methods: We conducted secondary data analysis of the two community-based studies conducted in 2012 and 2017 in the Magu Health and Demographic system site, in Tanzania. Information on fertility desires, HIV status, and social-economic and demographic variables were analyzed. Fertility desire was defined as whether or not the participant wanted to bear a child in the next two years. The main analysis used log-binomial regression to assess the association between fertility desire and HIV infection. Results: In the 2012 study, 43% (95% CI 40.7-45.3) of men and 33.3% (95% CI 31.8 - 35.0) women wanted another child in the next two years. In 2017 the percentage rose to 55.7% (95% CI 53.6 - 57.8) in men and 41.5% (95% CI 39.8 - 43.1) in women. Although fertility desire in men and women were higher in HIV uninfected compared to HIV infected, age-adjusted analysis did not show a statistical significance difference in both studies (2012: PR=1.02, 95%CI 0.835 - 1.174, p<0.915 and 2017: PR = 0.90 95%CI 0.743 - 1.084 p= 0.262). Discussion: One-third of women and forty percent of men desired for fertility in 2012, while forty percent of women and nearly half of men desired for fertility in 2017. The data showed fertility desire, in 2012 and 2017 were not related to HIV infection in both periods of ART coverage.

The barriers and facilitators of HIV-exposed infant testing as perceived by HIV-positive mothers in Botswana: A qualitative study

Background

Despite high rates of HIV testing and enrolment of HIV-positive pregnant women on antiretroviral therapy in Botswana, coverage for HIV-exposed infant (HEI) testing remains suboptimal. Many factors can contribute to suboptimal HEI testing rates, but they have seldom been thoroughly investigated in Botswana. Therefore, the aim of this study was to explore the experiences and perspectives of HIV-positive mothers on the barriers and facilitators of HEI testing to inform interventions to promote HEI testing in Botswana.

Methods

We conducted focus group discussions (FGDs) with HIV-positive mothers who gave birth in 2016 at the three largest public hospitals in Botswana. FGDs were held in Maun, Francistown, and Gaborone from September 2019 to March 2020. The maximum variation sampling method was used to select the participants using information that was abstracted from birth registers and other medical records at the study sites. Mothers were asked to describe their HEI testing experiences, what made it easy or difficult for them to return the HEI for testing, and what needs to be done to improve HEI testing in Botswana. A thematic approach was used to analyse the data.

Results

Fifteen FGDs with 142 mothers (aged 21–52 years) were held. Participants identified several facilitators to HEI testing, including a mother with adequate knowledge of PMTCT, intensive tracking of HEI by healthcare workers (HCWs), positive attitudes of HCWs toward clients, and social support from significant others. Staff shortages at health care facilities, frequent stock-outs of HIV test kits, fear of stigma, fear of positive test results for the child, and transportation challenges were identified as key barriers to HEI testing. Increasing staffing at healthcare facilities, having adequate supplies of HIV test kits, enhanced HEI tracking, easing access to HEI testing services in rural areas, and providing quality PMTCT education were among the proposed interventions to promote HEI testing.

Conclusion

Optimizing HEI testing in Botswana will require multi-level interventions at the policy, health system, community, interpersonal, and individual levels.

Pregnancy rates and outcomes in a longitudinal HIV cohort in the context of evolving antiretroviral treatment provision in South Africa

BACKGROUND

In South Africa, women continue to face a high burden of Human Immunodeficiency Virus (HIV) infection and the possible complications thereof during pregnancy. We assessed pregnancy incidence rates and outcomes in a longitudinal HIV cohort study over a 15-year period.

METHODS

We evaluated pregnancies among women ≥ 18 years between 2004 and 2019 in the CAPRISA 002 study. We analysed pregnancy rates following HIV acquisition, CD4 counts and HIV viral load dynamics and pregnancy outcomes. We used linear regression to assess if the mean CD4 and log10 viral load close to delivery increases or decreases linearly across three different timepoints.

RESULTS

In total 245 women enrolled into the HIV negative study phase, 225 into the HIV infection phase and 232 in the antiretroviral therapy (ART) phase. Median follow-up time was 2.0 years [Interquartile Range (IQR) 0.8-2.0] during the HIV negative phase, 2.6 years; (IQR) 1.2-4.8] during HIV infection and 3.7 years (IQR 1.8-5.0) on ART, with maximum follow-up time of 2, 10 and 6 years respectively. Overall, 169 pregnancies occurred in 140 women, of which 16 pregnancies were observed during acute or early HIV infection [Incidence Rate (IR) 8.0 per 100 women-years; 95% confidence interval (CI): 4.6-12.9], 48 during established infection [IR 9.3; (CI 6.8-12.3)] and 68 on ART [IR 8.9; (CI: 7.0 - 11.4)]. Birth outcomes from 155/169 (91.7%) pregnancies were 118 (76.1%) full term live births, 17 (10.9%) premature live births, 9 (5.8%) therapeutic/elective miscarriages, 8 (5.1%) spontaneous miscarriages and 3 (1.9%) spontaneous foetal deaths or stillbirths. Six mother-to-child transmission events occurred, with four documented prior to 2008. Over time, mean CD4 count in pregnant women increased from 395 cells/µL (2004-2009) to 543 cells/µL (2010-2014) and to 696 cells/µL (2015-2019), p < 0.001. Conversely, the viral load declined from 4.2 log10 copies/ml to 2.5 log10 copies/ml and to 1.2 log10 copies/ml (p < 0.001) for the corresponding periods.

CONCLUSIONS

Pregnancy rates following HIV acquisition were high, emphasising a need for timeous ART provision and contraception counselling in women recently diagnosed with HIV. CD4 count and HIV viral load trajectories reflect improvements in treatment guidance for pregnant women over time.

Decreasing incidence of pregnancy among HIV-positive adolescents in a large HIV treatment program in western Kenya between 2005 and 2017: a retrospective cohort study

BACKGROUND

The objective of this study was to estimate the prevalence, incidence and risk factors for pregnancy among HIV-positive adolescents in a large HIV treatment program in western Kenya.

METHODS

The Academic Model Providing Access to Healthcare (AMPATH) program is a partnership between Moi University, Moi Teaching and Referral Hospital and a consortium of 11 North American academic institutions. AMPATH currently provides care to 85,000 HIV-positive individuals in western Kenya. Included in this analysis were adolescents aged 10-19 enrolled in AMPATH between January 2005 and February 2017. Socio-demographic, behavioural, and clinical data at baseline and time-updated antiretroviral treatment (ART) data were extracted from the electronic medical records and summarized using descriptive statistics. Follow up time was defined as time of inclusion in the cohort until the date of first pregnancy or age 20, loss to follow up, death, or administrative censoring. Adolescent pregnancy rates and associated risk factors were determined.

RESULTS

There were 8565 adolescents eligible for analysis. Median age at enrolment in HIV care was 14.0 years. Only 17.7% had electricity at home and 14.4% had piped water, both indicators of a high level of poverty. 12.9% (1104) were pregnant at study inclusion. Of those not pregnant at enrolment, 5.6% (448) became pregnant at least once during follow-up. Another 1.0% (78) were pregnant at inclusion and became pregnant again during follow-up. The overall pregnancy incidence rate was 21.9 per 1000 woman years or 55.8 pregnancies per 1000 women. Between 2005 and 2017, pregnancy rates have decreased. Adolescents who became pregnant in follow-up were more likely to be older, to be married or living with a partner and to have at least one child already and less likely to be using family planning.

CONCLUSIONS

A considerable number of these HIV-positive adolescents presented at enrolment into HIV care as pregnant and many became pregnant as adolescents during follow-up. Pregnancy rates remain high but have decreased from 2005 to 2017. Adolescent-focused sexual and reproductive health and ante/postnatal care programs may have the potential to improve maternal and neonatal outcomes as well as further decrease pregnancy rates in this high-risk group.

Risk factors for Bordetella pertussis disease in hospitalized children

INTRODUCTION

Despite a resurgence of disease, risk factors for pertussis in children in low and middle-income countries are poorly understood. This study aimed to investigate risk factors for pertussis disease in African children hospitalized with severe LRTI.

METHODS

A prospective study of children hospitalized with severe LRTI in Cape Town, South Africa was conducted over a one-year period. Nasopharyngeal and induced sputum samples from child and nasopharyngeal sample from caregiver were tested for Bordetella pertussis using PCR (IS481+/hIS1001). History and clinical details were documented.

RESULTS

460 children with a median age of 8 (IQR 4-18) months were enrolled. B. pertussis infection was confirmed in 32 (7.0%). The adjusted risk of confirmed pertussis was significantly increased if infants were younger than two months [aRR 2.37 (95% CI 1.03-5.42]), HIV exposed but uninfected (aRR 3.53 [95% CI 1.04-12.01]) or HIV infected (aRR 4.35 [95% CI 1.24-15.29]). Mild (aRR 2.27 [95% CI 1.01-5.09]) or moderate (aRR 2.70 [95% CI 1.13-6.45]) under-nutrition in the children were also associated with higher risk. The highest adjusted risk occurred in children whose caregivers had B. pertussis detected from nasopharyngeal swabs (aRR 13.82 [95% CI 7.76-24.62]). Completion of the primary vaccine schedule (three or more doses) was protective (aRR 0.28 [95% CI 0.10-0.75]).

CONCLUSIONS

HIV exposure or infection, undernutrition as well as detection of maternal nasal B. pertussis were associated with increased risk of pertussis in African children, especially in young infants. Completed primary vaccination was protective. There is an urgent need to improve primary pertussis vaccine coverage in low and middle-income countries. Pertussis vaccination of pregnant women, especially those with HIV infection should be prioritized.

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.

Fertility among women living with HIV in western Ethiopia and : a cross-sectional study

OBJECTIVE

This study aimed to examine fertility (live births) in the last 3 years and its associated factors among women living with HIV (WLHIV) in western Ethiopia .

DESIGN

Participants were recruited into a cross-sectional survey using systematic sampling.

SETTINGS

Four healthcare facilities in western Ethiopia were included.

PARTICIPANTS

Eligible participants were WLHIV of reproductive age (15-49 years) from western Ethiopia who found out about their HIV-positive status more than 3 years ago (N=866).

PRIMARY OUTCOME MEASURES

The fertility (live births) of HIV-positive women in the last 3 years was surveyed using face-to-face interviews (March-June 2018). Logistic regression analyses were conducted to examine factors influencing fertility in the last 3 years.

RESULTS

A total of 108 (12.5%) HIV-positive women gave birth to 121 live children in the last 3 years. Of these births, 18.2% were reported as mistimed at conception, while 26.4% were reported as unwanted. Of the live births, 8.3% ended in death. Of the 76 (62.8%) children with known HIV status born to HIV-positive women in the last 3 years, 7.9% were HIV-positive. In terms of predictors of fertility, women aged 15-24 years (adjusted OR (AOR) 2.72; 95% CI 1.14 to 6.49) and 25-34 years (AOR 4.34; 95% CI 2.61 to 7.21) had increased odds of fertility compared with women aged 35-49 years. Women using antiretroviral therapy (ART) for less than 5 years were more likely to have given birth in the last 3 years compared with those using ART for 10 years or more (AOR 2.96; 95% CI 1.19 to 7.36), even after controlling for age.

CONCLUSIONS

WLHIV in Ethiopia are having children and so it is imperative that safe conception strategies are readily available as well as support to reduce HIV-related risks for children born to these mothers. Strengthening reproductive health services for HIV-positive women in order to achieve their family planning goals is therefore important.

Effect of antiretroviral therapy on fertility rate among women living with HIV in Tabora, Tanzania: An historical cohort study

The modelling of HIV trends in Tanzania uses surveillance data from antenatal clinics after adjusting for the reduction in fertility of women living with HIV (WLWH). The rollout of HIV care and treatment services has enabled many WLWH to start on antiretroviral treatment (ART) earlier and are counselled on the options to prevent HIV transmission to their children. The assumption that being HIV positive leads to lower fertility needs to be revisited. This study aims to quantify the effect of ART program expansion on the fertility rate of WLWH in Tanzania. We used Cox regression model to estimate fertility rate and associated factors among WLWH of reproductive age (15–49 years) who enrolled in HIV care and treatment at 57 centers in Tabora from 2008 to 2014. A decomposition of Poisson regression was used to explore the reasons for fertility rate differences observed among WLWH. A total of 6,397 WLWH aged 15–49 years were followed for a median time of 2.0 years. The total fertility rate of 48.8/1,000 person years (95%CI: 44.6 to 52.9/1,000) was inversely proportional to age and WHO clinical staging. WLWH on ART had higher fertility compared to those not started on ART (aHR = 1.5, 95%CI: 1.2–1.9). Being married or cohabiting, having higher CD4 cell count and not using contraceptives were associated with higher fertility rate. The fertility rate after post-ART initiation was 54.95/1,000 and among pre-ART users was 40.52/1,000, a difference of 14.43/1,000 in fertility rate between the groups. In the decomposition analysis, proximate determinants of fertility rate among WLWH on ART accounted for a 93.8% smaller increase than expected. In an era of ART expansion in Tabora region, fertility rates of WLWH increased. Higher fertility rates in women on ART may alter the estimation of HIV prevalence and incidence.

Reproductive needs of PLHIV in Jamaica: relationship between fertility desire, motives and depression

Background/objective: Advances in antiretroviral therapy and assisted reproduction technology which allow for longer and healthier lives and safer conception options necessitate a new understanding of the sexual and reproductive needs of persons living with HIV (PLHIV). This study examines fertility desire and motives for having children among PLHIV in Jamaica and explores the association with depressive symptoms.Methods: In a cross-sectional study, 251 PLHIV in their reproductive years voluntarily completed an interviewer-administered questionnaire. SPSS analyses involved bivariate and logistic regression models significant at p < .05.Results: A desire to have children was expressed by 66% (n = 166), mostly males and persons younger than 40 years. Of those in a current relationship (n = 126), not having previous children best predicted fertility desire (p = .001; CI 0.04-0.44) as well as motives to conceive (p = .02; CI 0.01-0.66). PLHIVs in their reproductive years who are at depression risk are those in a sero-discordant relationship (p = .01; CI 1.48-30.22) and who have been diagnosed between 1 and 4 years (p = .05; CI 0.01-1.04).Conclusions: HIV status does not dampen the desire to have future children. There is need to evaluate the sexual, reproductive and mental health needs of PLHIV.

Exploring the live birth rates of women living with HIV in British Columbia, Canada

OBJECTIVE

To evaluate the birth rates of women living with HIV (WLWH) compared to the general population in British Columbia (BC), Canada.

METHODS

We retrospectively reviewed clinical and population level surveillance data from 1997 to 2015. Live birth rates from 1997 to 2015 among WLWH aged 15-49 years were compared with those of all BC women. Next, the number of live births among WLWH with a live birth between 1997-2012 and HIV-negative controls matched 1:3 by geocode were compared.

RESULTS

WLWH had a lower birth rate compared to all BC women [31.4 (95%CI, 28.6-34.3) vs. 40.0 (39.3-40.1)/1000 person years]. Stratified by age, WLWH aged 15-24 years had a higher birth rate while WLWH aged 25-49 years had a lower birth rate than BC women (p<0.01). Between 1997 and 2015, birth rates for both populations decreased among women aged 15-24 years, and increased among women aged 25-49 years, most strikingly among WLWH 35-49 years (p<0.01). When comparing WLWH with a live birth to HIV-negative geocode matched controls, WLWH aged 15-24 years (p = 0.03) and aged 25-34 years (p<0.01) had more live births than controls while WLWH aged 35-49 years did not (p = 0.06).

CONCLUSIONS

On a population level, WLWH have lower birth rates than the general population. However, this is not observed among WLWH who have ever given birth compared with matched controls, suggesting that sociodemographic factors may play an important role. WLWH are increasingly giving birth in their later reproductive years. Taken together, our data supports the integration of reproductive health and HIV care.

Contraceptive use following unintended pregnancy among Ugandan women living with HIV

BACKGROUND

Preventing unintended pregnancy is critical for women living with HIV (WLWH) to safely achieve their reproductive goals. Family planning services should support WLWH at risk of repeat unintended pregnancies. We examined the relationship between unintended pregnancy and subsequent contraception use among WLWH in Uganda.

STUDY DESIGN

This was a retrospective analysis of data from a longitudinal cohort of individuals initiating antiretroviral therapy (ART), restricted to women with pregnancy (confirmed via urine β-hcg testing) between 2011-2013. The exposure of interest was intended vs unintended pregnancy, and the outcome was self-report of modern contraceptive use (hormonal methods, intrauterine device, sterilization, and/or consistent condom use) at 12 (range 6-18) months post-partum. A log-binomial model was used to estimate relative risks of modern contraceptive use post-partum based on intent of the index pregnancy, adjusted for age, socioeconomic status, education, relationship and HIV status of pregnancy partner, contraceptive use prior to pregnancy, years since HIV diagnosis, ART regimen, and CD4 cell count.

RESULTS

Among 455 women, 110 women reported 110 incident pregnancies with report on intent. Women had a baseline median age of 29 years, baseline CD4 count 403 cells/mm3, and were living with HIV for 3.8 years. Fifty pregnancies (45%) were reported as unintended and 60 (55%) as intended. Postpartum, 64% of women with unintended and 51% with intended pregnancy reported modern contraception (p = 0.24). In adjusted models, there was no association between pregnancy intent and post-partum contraception. However, contraceptive use prior to the referent pregnancy was positively associated with post-partum contraceptive use (aRR 1.97 (95% CI 1.12-3.48, p = 0.02), while higher baseline CD4 cell count was associated with lower post-partum contraceptive use (aRR 0.95, 95% CI 0.90-0.99, p = 0.02).

CONCLUSIONS

Almost half of incident pregnancies among WLWH in this cohort were unintended. Experiencing an unintended pregnancy was not associated with post-partum contraceptive use. Creative strategies to support contraceptive uptake for birth spacing and prevention of unintended pregnancies in the post-partum period are needed.

Mother-baby dyads enrolled in PMTCT care in western Kenya: characteristics and implications for ART programmes

The objective of the study was to establish the mother-baby pair characteristics that contribute to vertical transmission of HIV and elucidate on remediation. We assessed for factors increasing the odds of HIV transmission in children born to HIV-infected mothers in western Kenya. We used a retrospective study which reviewed routinely collected data of 1 028 mother-baby pairs enrolled in a prevention of mother-to-child transmission (PMTCT) programme in western Kenya from January to December 2015. We compared the transmission rates amongst mothers known to have a positive HIV status before conception (known positives/KPs) versus the transmission amongst those who were newly diagnosed during maternal and child health (MCH) clinic attendance (new positives/NPs). We compared the socio-demographic and clinical characteristics of the mothers using chi square and Kruskal-Wallis tests at 95% confidence interval (CI). We assessed for factors associated with the infants' HIV status using a logistic regression model. The results revealed that 60% (622) of the mothers were KPs, and that KPs and NPs had mother-to-child transmission (MTCT) rates of 5.5% and 20.7% respectively. Close to 90% of the NP Mothers were at an early HIV clinical stage at enrolment and 40% were enrolled after delivery. The infants of NPs were enrolled at a mean age of 18.3 weeks compared to 6.6 weeks for the infants of the KPs. On adjusted multivariable analysis, child's age at enrolment (AOR = 1.05, 95%CI = 1.036-1.064) and mother's status at conception (AOR = 1.96, 95%CI = 1.042-3.664) were significantly associated with the infant's HIV status. None of the HIV infected infants had received nevirapine prophylaxis. Most of the mothers enrolling into the PMTCT programme have a known HIV-positive status, however, NPs are the largest contributors to continued MTCT.

Pregnancy incidence and intention after HIV diagnosis among women living with HIV in Canada

BACKGROUND

Pregnancy incidence rates among women living with HIV (WLWH) have increased over time due to longer life expectancy, improved health status, and improved access to and HIV prevention benefits of combination antiretroviral therapy (cART). However, it is unclear whether intended or unintended pregnancies are contributing to observed increases.

METHODS

We analyzed retrospective data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS). Kaplan-Meier methods and GEE Poisson models were used to measure cumulative incidence and incidence rate of pregnancy after HIV diagnosis overall, and by pregnancy intention. We used multivariable logistic regression models to examine independent correlates of unintended pregnancy among the most recent/current pregnancy.

RESULTS

Of 1,165 WLWH included in this analysis, 278 (23.9%) women reported 492 pregnancies after HIV diagnosis, 60.8% of which were unintended. Unintended pregnancy incidence (24.6 per 1,000 Women-Years (WYs); 95% CI: 21.0, 28.7) was higher than intended pregnancy incidence (16.6 per 1,000 WYs; 95% CI: 13.8, 20.1) (Rate Ratio: 1.5, 95% CI: 1.2-1.8). Pregnancy incidence among WLWH who initiated cART before or during pregnancy (29.1 per 1000 WYs with 95% CI: 25.1, 33.8) was higher than among WLWH not on cART during pregnancy (11.9 per 1000 WYs; 95% CI: 9.5, 14.9) (Rate Ratio: 2.4, 95% CI: 2.0-3.0). Women with current or recent unintended pregnancy (vs. intended pregnancy) had higher adjusted odds of being single (AOR: 1.94; 95% CI: 1.10, 3.42), younger at time of conception (AOR: 0.95 per year increase, 95% CI: 0.90, 0.99), and being born in Canada (AOR: 2.76, 95% CI: 1.55, 4.92).

CONCLUSION

Nearly one-quarter of women reported pregnancy after HIV diagnosis, with 61% of all pregnancies reported as unintended. Integrated HIV and reproductive health care programming is required to better support WLWH to optimize pregnancy planning and outcomes and to prevent unintended pregnancy.

Incidence and Predictors of Pregnancy among Women on ART in Debre Markos Referral Hospital, Northwest Ethiopia: A Five-Year Retrospective Cohort Study

Globally, death of women due to HIV/AIDS related causes during pregnancy or within 42 days after pregnancy was estimated to be 37,000. In Ethiopia, 42,900 pregnant women living with HIV gave birth in the year 2011. This study was aimed to assess incidence and predictors of pregnancy among women on ART in Debre Markos Referral Hospital, Northwest Ethiopia. A retrospective cohort study was conducted using data recorded from September 2011 to August 2015. Data was extracted from February to March, 2016, from 1,239 records and analyzed using SPSS version 16. A Kaplan-Meier survival analysis was used to estimate the probabilities of being pregnant. The Cox proportional hazards model was done and results were expressed using hazard ratios with 95% CI. A total of 1,239 women on ART were included in the study. The incidence of pregnancy was 49.2 per 1,000 person-years. Living in rural, being married, being widowed, being unemployed, and having <2 children at enrollment were found to be positively associated with being pregnant. The incidence of pregnancy among women on ART was found to be considerable. Provision of family planning and other reproductive health interventions have to be coupled with the ART service to address the problem.

Pregnancy and HIV Disease Progression in an Early Infection Cohort from Five African Countries

BACKGROUND

Understanding associations between pregnancy and HIV disease progression is critical to provide appropriate counseling and care to HIV-positive women.

METHODS

From 2006 to 2011, women less than age 40 with incident HIV infection were enrolled in an early HIV infection cohort in Kenya, Rwanda, South Africa, Uganda, and Zambia. Time-dependent Cox models evaluated associations between pregnancy and HIV disease progression. Clinical progression was defined as a single CD4 measurement <200 cells/μl, percent CD4 <14%, or category C event, with censoring at antiretroviral (ART) initiation for reasons other than prevention of mother-to-child transmission (PMTCT). Immunologic progression was defined as two consecutive CD4s ≤350 cells/μl or a single CD4 ≤350 cells/μl followed by non-PMTCT ART initiation. Generalized estimating equations assessed changes in CD4 before and after pregnancy.

RESULTS

Among 222 women, 63 experienced clinical progression during 783.5 person-years at risk (8.0/100). Among 205 women, 87 experienced immunologic progression during 680.1 person-years at risk (12.8/100). The association between pregnancy and clinical progression was adjusted hazard ratio [aHR] = 0.7; 95% confidence interval (CI): 0.2, 1.8. The association between pregnancy and immunologic progression was aHR = 1.7; 95% CI: 0.9, 3.3. Models controlled for age; human leukocyte antigen alleles A*03:01, B*45, B*57; CD4 set point; and HIV-1 subtype. CD4 measurements before versus after pregnancies were not different.

CONCLUSIONS

In this cohort, pregnancy was not associated with increased clinical or immunologic HIV progression. Similarly, we did not observe meaningful deleterious associations of pregnancy with CD4s. Our findings suggest that HIV-positive women may become pregnant without harmful health effects occurring during the pregnancy. Evaluation of longer-term impact of pregnancy on progression is warranted.

Getting pregnant in HIV clinical trials: women's choice and safety needs. The experience from the ANRS12169-2LADY and ANRS12286-MOBIDIP trials

INTRODUCTION

Pregnancy is an exclusion criteria in most clinical trials involving antiretroviral therapy (ART) and modern contraception methods are systematically proposed to women of childbearing age. Nevertheless pregnancies are often observed. Reproductive choices during clinical trials should be understood to adapt interventions to the level of risk for mother and baby safety. Our goal was to describe the reproductive behavior and pregnancy outcomes among HIV-infected women on second-line antiretroviral treatment enrolled in two clinical trials and to compare them with those of HIV-positive women in non-research settings.

METHODS

The number and outcomes of pregnancies were recorded among 281 non menopausal women enrolled in the ANRS 12169-2LADY and ANRS 12286-MOBIDIP clinical trials in Cameroon, Senegal and Burkina Faso. All participants had agreed to use a least one contraceptive method (barrier or non-barrier) which was provided for free during the study. Data were collected through revision of pregnancy notification forms and by data extraction from the study database, regularly updated and checked during the study.

RESULTS

Sixty-six women had 84 pregnancies between January 2010 and July 2015 resulting in a pregnancy rate of 8.0 per 100 women-years (WY) (95% CI 6.5-9.9) which is similar to the ones observed in cohort studies in Sub-Saharan Africa (varying from 2.5 to 9.4 pregnancies per 100 WY). Among 60 live births, 10 (16.6%) were born prematurely and 9 (15%) had a low birth weight. Sixteen miscarriages/stillbirths occurred (19.5%). This percentage is comparable to the one expected in the seronegative population which is reassuring for HIV-positive women considering pregnancy on ART. Only one minor birth defect was diagnosed. In univariate and multivariate analysis, miscarriages/stillbirths were not associated either with age, nadir of CD4 count, duration of ART, CD4 count, or viral load at the beginning of pregnancy.

CONCLUSION

HIV-positive women participating in clinical trials conducted in Sub-Saharan Africa tend to get pregnant as often as seropositive women who received medical care in non-research settings. It is therefore essential to adopt a pragmatic approach by re-evaluating the relevance of the criteria for exclusion of pregnant women according to the risk associated with exposure and to seek more effective and innovating contraceptive strategies when using potentially teratogenic molecules.

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.

Pregnancy rate and birth outcomes among women receiving antiretroviral therapy in Burkina Faso: a retrospective cohort study

INTRODUCTION

In Sub-Saharan Africa, few studies reported pregnancy incidence and outcomes in women taking antiretroviral therapy (ART). This survey aims to estimate the incidence and outcomes of pregnancy in a cohort of HIV positive women initiating ART in Bobo-Dioulasso, Burkina Faso.

METHODS

We carried out a retrospective cohort study. We selected women in childbearing age initiating ART and followed up in Bobo-Dioulasso teaching hospital between January 2005 and June 2011. The incidence of pregnancies during follow-up was calculated. Childbirth was defined by the expulsion of a fetus after 22 weeks of amenorrhea. Before this term, it is an abortion. Childbirth is said premature if it occurs before 37 weeks of gestation, to term if it occurs between the 38th and the 42nd week. The annual age-standardized fertility rates were calculated using the baseline population from the 2010 demographic and health survey (DHS) in Burkina Faso.

RESULTS

A total of 1,763 women of childbearing age under ART were included in the study. They ranged between 18 and 48 years old with a median of 35 years old. A total of 222 pregnancies were observed during 4639 women-years of follow-up, corresponding to an incidence density of 5 pregnancies for 100 women-years (95% CI: 4.2-5.5). Among the 222 pregnancies recorded, 9(4.0%) ended with abortion, 205(92.4%) with childbirth (including 15 premature childbirths); the outcome of 8(3.6%) pregnancies were unknown abortion. Live birth and stillborn rates were 94.0% (193/205) and 6.0% respectively. The standard fertility rate in our cohort was 45 live births for 1,000 women-years. The general decrease in fertility rates was 66.0% among women infected with HIV compared to the overall population.

CONCLUSION

This study shows a low pregnancy incidence among women initiating ART as compared to their peers from the general population. Pregnancies that occurred during ART generally end with live births. Care packages for HIV infected women of childbearing age must include reproductive health services to better address this issue.

Combination Antiretroviral Therapy for HIV in Rwandan Adults: Clinical Outcomes and Impact on Reproductive Health up to 24 Months

Adult women (n = 113) and men (n = 100) initiating combination antiretroviral therapy (cART) and women not yet eligible for cART (n = 199) in Kigali, Rwanda, were followed for 6–24 months between 2007 and 2010. In the cART groups, 21% of patients required a drug change due to side effects and 11% of patients had virological failure (defined as >1,000 HIV RNA copies/mL) after 12 months of cART. About a third of the pregnancies since HIV diagnosis were unintended. The proportion of women in the pre-cART group using modern contraception other than condoms (50%) was similar to women in the general population, but this proportion was only 25% in women initiating cART. Of the women who carried at least one pregnancy to term since having been diagnosed HIV-positive, a third reported to have participated in a prevention-of-mother-to-child-transmission (PMTCT, option A) intervention. Many patients were coinfected with herpes simplex virus type 2 (79–92%), human papillomavirus (38–53%), and bacterial sexually transmitted infections (STIs) with no differences between groups. We applaud the Rwandan government for having strengthened family planning and PMTCT services and for having introduced HPV vaccination in recent years, but additional work is needed to strengthen STI and HPV-related cancer screening and management in the HIV-positive population.
