Risk factors during pregnancy and birth-related complications in HIV-positive versus HIV-negative women in Denmark, 2002-2014

Impact of maternal HIV infection on perinatal outcomes: A systematic review

BACKGROUND

Maternal HIV infection remains a significant global health concern with potential repercussions on perinatal outcomes. Emphasis on early intervention to improve peri- and postnatal outcomes in infected mothers and infants is a valid therapeutic concern.

OBJECTIVES

To comprehensively analyze perinatal outcomes associated with maternal HIV infection and evaluate adverse effects associated with the HIV infection in the existing literature.

SEARCH STRATEGY

A comprehensive search of PubMed, MEDLINE, and Google Scholar was conducted from 2013 to September 2023, using relevant MeSH terms.

SELECTION CRITERIA

The included studies encompassed original studies, cross-sectional, prospective, retrospective studies and observational studies focused on perinatal outcomes in the context of maternal HIV infection.

DATA COLLECTION AND ANALYSIS

The selected studies underwent rigorous data collection and comprehensive quality checks and adhered to the PRISMA guidelines.

MAIN RESULTS

Nine eligible studies from Brazil, China, India, Malawi, Nigeria, Tanzania, the USA, and Canada were included. These studies have consistently demonstrated that maternal HIV infection is associated with adverse perinatal outcomes. The analysis revealed a higher risk of preterm birth (OR 1.57, 95% CI: 1.39-1.78), low birth weight (OR 1.33, 95% CI: 1.18-1.49), and small for gestational age (OR 1.38, 95% CI: 1.24-1.53) among infants born to mothers living with HIV. Notably, the impact of antiretroviral treatment (ART) on these outcomes varied, but maternal HIV infection remained a significant risk factor regardless of income level and geographic region.

CONCLUSION

Maternal HIV infection is consistently associated with adverse perinatal outcomes, emphasizing the need for targeted interventions and improved prenatal care in pregnant women with HIV infection.

Fetal Clinical and Paraclinical Outcomes in HIV-Positive Pregnant Women

Background Adverse pregnancy outcomes in women with human immunodeficiency virus (HIV) infection remain significantly increased. Untreated maternal infection primarily leads to fetal complications, such as intrauterine growth restriction, stillbirth, or preterm birth. Concerning both maternal and fetal complications that can appear in pregnancy associated with HIV infection, the purpose of the study was to determine fetal and maternal demographic characteristics and the correlation between blood count parameters and poor fetal prognosis. Methods We conducted a quantitative study utilizing document review as the data collection method. This study encompassed a cohort of nine HIV-positive pregnant women who delivered at the Obstetrics and Gynecology Department of the University Emergency Hospital in Bucharest from January 1, 2021, to December 31, 2023. A comparative cohort of nine healthy pregnant women who delivered during the same period in the same facility was selected using stratified random sampling. We examined maternal and fetal demographic parameters and neonatal outcomes, reporting them to paraclinical laboratory data. Results The incidence of pregnancy-related HIV infections was 0.16%. The mean age of patients in the selected group was 29.88 ± 5.53. There was no statistically significant correlation between maternal clinical and paraclinical parameters in the HIV-positive and HIV-negative groups. Although there was a slightly negative difference in the fetal weight at birth, the 1-min APGAR (appearance, pulse, grimace, activity, and respiration) score, and the intrauterine growth restriction between the two groups, there was a statistically significant association between admission to the neonatal intensive care unit (NICU) and the neonates from HIV-positive pregnancies. In our study, we observed preterm deliveries in 22.22% of cases, and we did not record any stillbirths. The 1-min APGAR score was correlated with the value of leukocytes in peripheral blood. Vertical transmission was established to be 11.11% independent of maternal blood count parameters. Conclusion HIV infection during pregnancy leads to a higher risk of admission to the NICU. Fetal leukocytosis is indicative of a lower 1-min APGAR score. The primary emphasis of therapeutic intervention during pregnancy should center on vigilant monitoring of maternal viral load and the timely administration of antiretroviral therapy to enhance fetal outcomes.

Reproductive Decision Making of Spanish Women Living With HIV: A Constructivist Grounded Theory Study

ABSTRACT

The process of reproductive decision making among women living with HIV is intricate and multifaceted, influenced by health considerations, societal factors, and personal values. In this study, we employed Charmaz's Constructivist Grounded Theory to understand how Spanish women living with HIV make decisions regarding reproduction. We conducted 26 face-to-face interviews until data saturation was achieved. Findings suggested that social constructs such as femininity and motherhood play a significant role in the reproductive decision-making process for women living with HIV. The women's beliefs about HIV, doubts, marginalizing situations, and health barriers create challenges to making reproductive decisions. These findings provide valuable implications for designing care plans that meet the unique sexual and reproductive health needs of women with HIV. An integrated and comprehensive multidisciplinary counseling approach is necessary to improve the quality of care.

Associations of HIV and antiretroviral therapy with gestational diabetes in South Africa

OBJECTIVE

To estimate associations of HIV status and antiretroviral (ART) regimen with gestational diabetes (GDM) and postpartum glucose metabolism.

DESIGN

Prospective cohort study.

METHODS

We enrolled pregnant persons with HIV (PWH) and without HIV in Cape Town, South Africa who were at least 18 years of age at 24-28 weeks' gestation and followed up to 26 months postpartum. Participants were tested for GDM in pregnancy and for diabetes postpartum using a 75 g 2 h oral glucose tolerance test (OGTT) and diagnosed via WHO criteria. We estimated associations of HIV status and ART regime [efavirenz (EFV) versus dolutegravir (DTG)] with GDM and postpartum impaired glucose metabolism using multivariable log binomial or linear regression models.

RESULTS

Among 397 participants [median age 30 (interquartile range (IQR) 25-34; n  = 198 without HIV, n  = 199 PWH], the prevalence of GDM was 6% (9 PWH versus 3% without HIV). In multivariable analyses, PWH were at higher risk of GDM [risk ratio (RR) 3.9, 95% confidence interval (CI) 1.4-10.7] after adjustment for prepregnancy BMI and other confounders. GDM risk did not differ by ART regimen (unadjusted prevalence 8.1% DTG versus 5.6% EFV, adjusted RR 1.1, 95% CI 0.2-6.6). Few participants had diabetes, impaired glucose tolerance (IGT), or impaired fasting glucose postpartum ( n  = 13, 6%) with no differences by HIV or ART status.

CONCLUSION

In a setting of universal GDM testing, PWH had an increased risk of impaired glucose metabolism during pregnancy but not postpartum. Among PWH, GDM risk was similar regardless of EFV or DTG use. Given concerns about DTG and weight gain, diabetes risk should continue to be monitored.

Adverse perinatal outcomes associated with prenatal exposure to protease-inhibitor-based versus non-nucleoside reverse transcriptase inhibitor-based antiretroviral combinations in pregnant women with HIV infection: a systematic review and meta-analysis

BACKGROUND

About 1.3 million pregnant women lived with HIV and were eligible to receive antiretroviral therapy (ART) worldwide in 2021. The World Health Organization recommends protease inhibitors (PI)-based regimen as second or third-line during pregnancy. With remaining pregnant women exposed to PIs, there is still an interest to assess whether this treatment affects perinatal outcomes. Adverse perinatal outcomes after prenatal exposure to PI-based ART remain conflicting: some studies report an increased risk of preterm birth (PTB) and low-birth-weight (LBW), while others do not find these results. We assessed adverse perinatal outcomes associated with prenatal exposure to PI-based compared with non-nucleoside reverse transcriptase (NNRTI)-based ART.

METHODS

We performed a systematic review searching PubMed, Reprotox, Clinical Trial Registry (clinicaltrials.gov) and abstracts of HIV conferences between 01/01/2002 and 29/10/2021. We used Oxford and Newcastle-Ottawa scales to assess the methodological quality. Studied perinatal outcomes were spontaneous abortion, stillbirth, congenital abnormalities, PTB (< 37 weeks of gestation), very preterm birth (VPTB, < 32 weeks of gestation), LBW (< 2500 grs), very low-birth-weight (VLBW, < 1500 g), small for gestational age (SGA) and very small for gestational age (VSGA). The association between prenatal exposure to PI-based compared to NNRTI-based ART was measured for each adverse perinatal outcome using random-effect meta-analysis to estimate pooled relative risks (RR) and their corresponding 95% confidence intervals (CI). Pre-specified analyses were stratified according to country income and study quality assessment, and summarized when homogeneous.

RESULTS

Out of the 49,171 citations identified, our systematic review included 32 published studies, assessing 45,427 pregnant women. There was no significant association between prenatal exposure to PIs compared to NNRTIs for VPTB, LBW, SGA, stillbirth, and congenital abnormalities. However, it was inconclusive for PTB, and PI-based ART is significantly associated with an increased risk of VSGA (sRR 1.41 [1.08-1.84]; I² = 0%) compared to NNRTIs.

CONCLUSIONS

We did not report any significant association between prenatal exposure to PIs vs NNRTIs-based regimens for most of the adverse perinatal outcomes, except for VSGA significantly increased (+ 41%). The evaluation of antiretroviral exposure on pregnancy outcomes remains crucial to fully assess the benefice-risk balance, when prescribing ART in women of reproductive potential with HIV.

Fetal Growth Restriction and Clinical Parameters of Newborns from HIV-Infected Romanian Women

Background and Objectives: The present study assessed the fetal growth restriction and clinical parameters of both human immunodeficiency virus (HIV)-negative and HIV-positive newborns from HIV-infected mothers in two HIV-acquired immunodeficiency syndrome regional centers (RCs) in Constanta and Craiova, Romania, in order to evaluate the adverse birth-related outcomes. Materials and Methods: These represent a retrospective study conducted between 2008 and 2019, in which 408 pregnant HIV-positive women, 244 from Constanta RC and 164 from Craiova RC, were eligible to participate in the study. Consecutive singleton pregnancies delivered beyond 24 weeks of pregnancy were included. Growth restriction in newborns was defined as the birth weight (BW) being less than the third percentile, or three out of the following: BW < 10th percentile; head circumference (HC) < 10th percentile; birth length (BL) < 10th percentile; prenatal diagnosis of fetal growth restriction; and maternal pregnancy information. Of the 244 newborns delivered in Constanta, RC, 17 were HIV-positive, while in Craiova, RC, of the 164 newborns, 9 were HIV-positive. All HIV-positive women were on combined antiretroviral therapy (cART) during pregnancy, similar to all HIV-positive newborns who received ARTs for the first six weeks. We search for the influence of anthropometrical parameters (i.e., HC, BL, and BW), as well as clinical parameters (i.e., newborn sex and Apgar score) for both HIV-negative and HIV-positive newborns, along with the survival rate of HIV-positive newborns. Results: There were no differences in the sex of the newborns within either group, with more than 50% being boys. Similarly, the Apgar score did not show any statistically significant values between the two groups (i.e., p = 0.544 for HIV-positive newborns vs. p = 0.108 for HIV-negative newborns). Interestingly, our results showed that in Craiova, RC, there was a chance of 2.16 to find an HIV-negative newborn with an HC < 10th percentile and a 2.54 chance to find an HIV-negative newborn with a BL < 10th percentile compared to Constanta, RC, without any significant differences. On the contrary, Constanta, RC, represented a higher risk of death (i.e., 3.049 times, p = 0.0470) for HIV-positive newborns compared to Craiova, RC. Conclusions: Our results support the idea that follow-up of fetal growth restriction should be part of postnatal care in this high-risk population to improve adverse birth-related outcomes.

Epidemiologia do HIV em gestantes e sua relação com o período da pandemia de COVID-19

RESUMO Objetivo: Analisar, à luz da Teoria Social Ecológica, a evolução dos casos notificados de HIV na gestação em um estado brasileiro e sua relação com o início da pandemia de COVID-19. Método: Estudo retrospectivo, com amostra composta por todas as notificações de HIV gestacional do estado do Ceará - Brasil no período de 2017 a 2021, na plataforma IntegraSUS. A coleta de dados foi realizada em janeiro de 2022. As variáveis analisadas foram organizadas de acordo com os níveis teóricos: macrossistema, exossistema, mesossistema e microssistema. Resultados: Foram registrados 1.173 casos de HIV em gestantes. Ao comparar o período pré e pós-pandemia, observou-se redução da taxa de detecção da doença (de 231 para 122,67 gestantes) e 1,82 vezes mais chances de as mulheres não usarem antirretrovirais no parto após o início da pandemia. Houve redução de 55% de partos vaginais e de 39% de cesarianas das mulheres com diagnóstico de HIV após o início da pandemia. Conclusão A pandemia de COVID-19 causou impacto epidemiológico e assistencial, levando a uma redução do número de notificações e taxa de detecção de gestantes que vivem com HIV no estado do Ceará. Logo, reforça-se a necessidade de assegurar a cobertura de atenção à saúde, com ações de diagnóstico precoce, garantia de tratamento e uma assistência pré-natal de qualidade.

Epidemiology of HIV in pregnant women and its relationship with the period of the COVID-19 pandemic

OBJECTIVE

To analyze, in the light of the Social Ecological Theory, the progression of reported cases of HIV during pregnancy in a Brazilian state and their relationship with the onset of the COVID-19 pandemic.

METHOD

Retrospective study, with a sample consisting of all reports of gestational HIV in the state of Ceará - Brazil from 2017 to 2021, on the IntegraSUS platform. Data collection was carried out in January 2022. The analyzed variables were organized according to the theoretical levels: macrosystem, exosystem, mesosystem, and microsystem.

RESULTS

A total of 1,173 cases of HIV in pregnant women were recorded. When comparing the pre- and post-pandemic period, a reduction in the disease detection rate (from 231 to 122.67 pregnant women) was observed, as well as 1.82 times more chances of women not using antiretrovirals during childbirth after the start of the pandemic. There was a 55% reduction in vaginal births and 39% in cesarean sections among women diagnosed with HIV after the start of the pandemic.

CONCLUSION

The COVID-19 pandemic had an epidemiological and care impact, leading to a reduction in the number of notifications and in the detection rate of pregnant women living with HIV in the state of Ceará. Therefore, the need to ensure health care coverage is emphasized, with early diagnosis actions, guaranteed treatment, and quality prenatal care.

Clinical and programmatic outcomes of HIV-exposed infants enrolled in care at geographically diverse clinics, 1997-2021: A cohort study

BACKGROUND

Although 1·3 million women with HIV give birth annually, care and outcomes for HIV-exposed infants remain incompletely understood. We analyzed programmatic and health indicators in a large, multidecade global dataset of linked mother-infant records from clinics and programs associated with the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium.

METHODS AND FINDINGS

HIV-exposed infants were eligible for this retrospective cohort analysis if enrolled at <18 months at 198 clinics in 10 countries across 5 IeDEA regions: East Africa (EA), Central Africa (CA), West Africa (WA), Southern Africa (SA), and the Caribbean, Central, and South America network (CCASAnet). We estimated cumulative incidences of DNA PCR testing, loss to follow-up (LTFU), HIV diagnosis, and death through 24 months of age using proportional subdistribution hazard models accounting for competing risks. Competing risks were transfer, care withdrawal, and confirmation of negative HIV status, along with LTFU and death, when not the outcome of interest. In CA and EA, we quantified associations between maternal/infant characteristics and each outcome. A total of 82,067 infants (47,300 EA, 10,699 CA, 6,503 WA, 15,770 SA, 1,795 CCASAnet) born from 1997 to 2021 were included. Maternal antiretroviral therapy (ART) use during pregnancy ranged from 65·6% (CCASAnet) to 89·5% (EA), with improvements in all regions over time. Twenty-four-month cumulative incidences varied widely across regions, ranging from 12·3% (95% confidence limit [CL], 11·2%,13·5%) in WA to 94·8% (95% CL, 94·6%,95·1%) in EA for DNA PCR testing; 56·2% (95% CL, 55·2%,57·1%) in EA to 98·5% (95% CL, 98·3%,98·7%) in WA for LTFU; 1·9% (95% CL, 1·6%,2·3%) in WA to 10·3% (95% CL, 9·7%,10·9%) in EA for HIV diagnosis; and 0·5% (95% CL, 0·2%,1·0%) in CCASAnet to 4·7% (95% CL, 4·4%,5·0%) in EA for death. Although infant retention did not improve, HIV diagnosis and death decreased over time, and in EA, the cumulative incidence of HIV diagnosis decreased substantially, declining to 2·9% (95% CL, 1·5%,5·4%) in 2020. Maternal ART was associated with decreased infant mortality (subdistribution hazard ratio [sdHR], 0·65; 95% CL, 0·47,0·91 in EA, and sdHR, 0·51; 95% CL, 0·36,0·74 in CA) and HIV diagnosis (sdHR, 0·40; 95% CL, 0·31,0·50 in EA, and sdHR, 0·41; 95% CL, 0·31,0·54 in CA). Study limitations include potential misclassification of outcomes in real-world service delivery data and possible nonrepresentativeness of IeDEA sites and the population of HIV-exposed infants they serve.

CONCLUSIONS

While there was marked regional and temporal heterogeneity in clinical and programmatic outcomes, infant LTFU was high across all regions and time periods. Further efforts are needed to keep HIV-exposed infants in care to receive essential services to reduce HIV infection and mortality.

Use of antiretroviral therapy in pregnancy and association with birth outcome among women living with HIV in Denmark: A nationwide, population-based cohort study

Objective

To describe antiretroviral therapy (ART) regimens during pregnancy among women living with HIV (WLWH) in Denmark and to examine the association between ART use in pregnancy and adverse birth outcomes.

Methods

A population‐based cohort study including all pregnancies among WLWH in Denmark between 2000 and 2019. Data were collected through national registries. Temporal trends of ART use in pregnancy were evaluated. Logistic regression models were used to examine the association of ART use in pregnancy and other risk factors with adverse birth outcomes.

Results

In total, 589 pregnancies were included. Combination treatment with a nucleoside reverse transcriptase inhibitor (NRTI) and a protease inhibitor (PI) was the most common ART regimen (96%). ART regimen, PI use in pregnancy and timing of ART initiation were not significantly associated with increased odds of preterm birth, small for gestational age or low birth weight. First‐trimester initiation of ART was significantly associated with increased odds of intrauterine growth restriction in the multivariate analysis [adjusted odds ratio (aOR) = 3.78, 95% confidence interval (CI): 1.23–11.59], while first trimester PI use was associated with increased odds of IUGR in the univariate analysis only [OR = 3.24, 95% CI: 1.13–9.30]. Smoking, comorbidity, and maternal HIV RNA ≥ 50 copies/mL were independently associated with increased odds of adverse birth outcomes.

Conclusions

Pregnant WLWH living in Denmark are generally well treated with HIV RNA < 50 copies/mL at delivery and NRTI + PI as the most common ART regimen used in pregnancy. Initiation of ART in the first trimester may be associated with poor fetal growth. The association between ART use in pregnancy and adverse birth outcomes may partly be explained by maternal risk factors.

Associations between HIV, antiretroviral therapy and preterm birth in the US Women's Interagency HIV Study, 1995-2018: a prospective cohort

OBJECTIVE

To evaluate the associations of HIV infection with preterm birth (PTB), and of HIV antiretroviral therapy (ART) with PTB.

METHODS

We analysed singleton live-born pregnancies among women from 1995 to 2019 in the Women's Interagency HIV Study, a prospective cohort of US women with, or at risk for, HIV. The primary exposures were HIV status and ART use before delivery [none, monotherapy or dual therapy, or highly active antiretroviral therapy (HAART)]. The primary outcome was PTB < 34 weeks, and, secondarily, < 28 and < 37 weeks. We analysed self-reported birth data, and separately modelled the associations between HIV and PTB, and between ART and PTB, among women with HIV. We used modified Poisson regression, and adjusted for age, race, parity, tobacco use and delivery year, and, when modelling the impact of ART, duration from HIV diagnosis to delivery, nadir CD4 count, and pre-pregnancy viral load and CD4 count.

RESULTS

We analysed 488 singleton deliveries (56% exposed to HIV) to 383 women. The risk of PTB < 34 weeks was similar among women with and without HIV, but the risk of PTB < 37 weeks was higher [32% vs. 23%; adjusted risk ratio (aRR) = 1.43; 95% confidence interval (CI): 1.07-1.91] among women with HIV. The risk of PTB < 34 weeks was lower among women with HIV receiving HAART than among those receiving no ART (7% vs. 26%; aRR:0.19; 95% CI: 0.08-0.44). The associations between HAART and PTB < 28 and < 37 weeks were similar.

CONCLUSIONS

Antiretroviral therapy exposure was associated with a decreased risk of PTB among a US cohort of women with HIV. Given the growing concerns about ART and adverse pregnancy outcomes, this finding that ART may be protective for PTB is reassuring.

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.

In utero exposure to antiretroviral drugs and pregnancy outcomes: Analysis of the French ANRS pharmacovigilance database

AIMS

In 2018, 1.07 million pregnant women received antiretroviral drugs, raising whether this affects pregnancy outcomes. We assessed the adverse pregnancy outcomes associated with prenatal antiretroviral drug exposure, notified to the French ANRS pharmacovigilance system.

METHODS

An exhaustive case report series has been performed using the ANRS pharmacovigilance database. All ANRS-sponsored HIV clinical research studies using antiretroviral drugs either in pregnant women or women of childbearing age were eligible from 2004 to 2019. We analysed the following pregnancy outcomes: abortion, ectopic pregnancy, stillbirth, prematurity (<37 weeks of gestational age), low birth weight (<2500 g) and congenital abnormalities. A logistic regression was performed to assess the odds ratio (OR) for each outcome separately (if occurrence >50) compared to the outcome observed when exposed to non-nucleoside-reverse-transcriptase-inhibitor (NNRTI)-based regimen as the reference.

RESULTS

Among the 34 studies selected, 918 deliveries occurred, of whom 88% had pregnancy outcomes documented. Pregnant women were mainly exposed to PI (n = 387, 48.6%), NNRTI (n = 331, 41.5%) and INI-based combinations (n = 40, 5.0%, 18 on dolutegravir). Compared to NNRTI-based combinations, there was no significant association observed with exposure to other antiretroviral combination for spontaneous abortion, prematurity or low birth weight, except an increased risk of low birth weight in new-born exposed to exclusive nucleoside-reverse-transcriptase-inhibitor (NRTI) combinations (n = 4; OR 7.50 [1.49-37.83]).

CONCLUSIONS

Our study, mainly based on protease inhibitor (PI) and NNRTI-based regimens, is overall reassuring on the risk of adverse pregnancy outcomes, except for NRTI which should be interpreted cautiously (small number, indication bias). In this study, the number of integrase inhibitor (INI)-based combinations was too low to draw any conclusions.

The Danish HIV Birth Cohort (DHBC) - a nationwide, prospective cohort

PURPOSE

The purpose of the Danish HIV Birth Cohort (DHBC) is to investigate the significance of HIV-1 infection in pregnancy and after delivery in women living with HIV (WLWH) in Denmark and their children, in the era of antiretroviral therapy and other interventions for treatment and prophylaxis.

PARTICIPANTS

All WLWH giving birth to one or more children in Denmark after 31 December 1999 are included, with consecutive ongoing enrolment, if they are living with HIV and pregnant, or if they are diagnosed with HIV in relation to pregnancy, delivery or shortly after delivery.

FINDINGS TO DATE

DHBC has been used to describe trends in the management of pregnancies in WLWH and their outcomes on a nationwide basis, mode of delivery and predictors of emergency caesarean section as well as risk factors during pregnancy in WLWH for birth-related complications compared with women from the general population (WGP). We have found that HIV-exposed, but uninfected (HEU) children born to WLWH had a lower median birth weight and gestational age and were at higher risk of intrauterine growth retardation than children born to WGP. We have investigated risk of in-hospital admission and use of antibiotics during the first 4 years of life among HEU children and showed that HEU children had an increased risk of overall hospital admission compared with a matched control group of unexposed children.Further, we compared anthropometric outcomes in children with a matched control group of children not exposed to HIV.

FUTURE PLANS

To continuously investigate the significance of HIV infection and antiretroviral therapy in pregnancy and after delivery in WLWH in Denmark and their HEU children and compare these findings with children born to WGP.
