Attrition from care and its predictors among women exposed to dolutegravir- and efavirenz-based first-line antiretroviral therapy in Ethiopia: a before-and-after study.

Background: The effect of dolutegravir (DTG)-based regimens on reducing attrition from care among women enrolled in the prevention of mother-to-child transmission (PMTCT) care program is unknown. Therefore, this study aimed to compare the incidence of attrition among women exposed to DTG-based with those exposed to efavirenz (EFV)-based first-line antiretroviral therapy (ART) in Ethiopia. Methods: An uncontrolled before-and-after study was conducted involving 932 women (with 466 on EFV-based and 466 on DTG-based regimens) who were enrolled in the PMTCT care program from September 2015 to February 2023. The outcome variable was attrition (i.e., maternal death or loss to follow-up before their infants' final HIV status was determined). A Kaplan-Meier estimator was employed to estimate the probability of attrition. The Cox proportional hazards regression model was fitted to identify predictor variables. The adjusted hazard ratio (aHR) with the corresponding 95% confidence interval (CI) was calculated to examine the risk difference in the comparison groups. Results: The cumulative incidence of attrition among women was 5.2% (3.0% for those placed in the DTG-based regimen arm and 7.3% for those placed in the EFV-based regimen arm). Women on DTG-based regimens had a 57% (aHR: 0.43; 95% CI: 0.23-0.80) lower risk of attrition from care compared to those on EFV-based regimens. Women who delivered their infants at home (aHR: 2.35; 95% CI: 1.14-4.85), had poor/fair adherence (aHR: 3.23; 95% CI: 1.62-6.45), had unsuppressed/unknown viral load status (aHR: 2.61; 95% CI: 1.42-4.79), and did not disclose their status to partners (aHR: 2.56; 95% CI: 1.34-4.92) had a higher risk of attrition from PMTCT care compared to their counterparts. Conclusion: The cumulative incidence of attrition among women receiving PMTCT care is optimal. In addition, the risk of attrition among women receiving DTG-based regimens is lower than that among women receiving EFV-based regimens. Thus, DTG-based first-line ART regimen supplementation should be sustained to achieve a national retention target of 95% and above.

Group B streptococci in newborns in the first three months of life.

Group B Streptococcus (GBS) disease in neonates occurs in two forms: early-onset disease (EOD), (day 0-6), and late-onset disease (LOD), (day 7-90). This review investigates that risk-based intrapartum screening and antibiotics have reduced the incidence of EOD, but not LOD, in Denmark. No clinical or laboratory tests can rule out GBS disease at symptom onset. Thus, a high proportion of uninfected infants receive antibiotics, although this varies widely, and may be reduced by strategies of antibiotic stewardship. A future GBS vaccine for pregnant women may potentially reduce disease burden and antibiotic exposure.

Evaluating the performance of a risk assessment score tool to predict HIV acquisition among pregnant and postpartum women in Kenya.

BACKGROUND: Clinical risk score tools require validation in diverse settings and populations before they are widely implemented. We aimed to externally validate an HIV risk assessment tool for predicting HIV acquisition among pregnant and postpartum women. In the context of prevention of mother-to-child transmission programs, risk score tools could be used to prioritize retesting efforts and delivery of pre-exposure prophylaxis (PrEP) to pregnant and postpartum women most at risk for HIV acquisition while minimizing unnecessary perinatal exposure. METHODS: Data from women enrolled in a cross-sectional study of programmatic HIV retesting and/or receiving maternal and child health care services at five facilities in Western Kenya were used to validate the predictive ability of a simplified risk score previously developed for pregnant/postpartum women. Incident HIV infections were defined as new HIV diagnoses following confirmed negative or unknown status during pregnancy. Predictive performance was assessed using the area under the receiver operating characteristic curve (AUC) and Brier score. RESULTS: Among 1266 women with 35 incident HIV infections, we found an AUC for predicting HIV acquisition of 0.60 (95% CI, 0.51, 0.69), with a Brier score of 0.27. A risk score >6 was associated with a 2.9-fold increase in the odds of HIV acquisition (95% CI, 1.48, 5.70; p = 0.002) vs scores ≤6. Women with risk scores >6 were 27% (346/1266) of the population but accounted for 52% of HIV acquisitions. Syphilis, age at sexual debut, and unknown partner HIV status were significantly associated with increased risk of HIV in this cohort. CONCLUSION: The simplified risk score performed moderately at predicting risk of HIV acquisition in this population of pregnant and postpartum women and may be useful to guide PrEP use or counseling.

Proportion of HIV exposed infants aged 0-6 months that missed nevirapine prophylaxis in Mulago National Referral Hospital, Uganda: a cross-sectional study.

BACKGROUND: Nevirapine prophylaxis has been found to lower the risk of HIV transmission in breastfed infants. While about 95% of HIV positive pregnant and lactating mothers use Antiretroviral therapy in Uganda, a smaller percentage of HIV exposed infants (HEI) receive nevirapine (NVP) prophylaxis. This study aimed to determine the proportion of HEI who missed NVP prophylaxis and associated factors. METHODS: This was a cross-sectional study done using quantitative methods, conducted at Mulago National Referral Hospital (MNRH). A total of 228 mother-infant pairs were enrolled. The proportion of HEI who missed NVP, maternal, infant and health facility factors associated were determined using a pre-tested questionnaire. Bivariate analysis and binary logistic regression model were used to determine the proportion and factors associated with missing NVP prophylaxis. RESULTS: The proportion of HEI who missed NVP prophylaxis was 50/228 (21.9%). Factors significantly associated with HEI missing NVP prophylaxis included delivery from outside government health facilities (AOR = 8.41; P = 0.001), mothers not undergoing PMTCT counselling (AOR = 12.01; P = 0.001), not on ART (AOR = 8.47; P = 0.003) and not having disclosed their HIV status to their partners (AOR = 2.80; P = 0.001). The HEI that missed nevirapine and were HIV positive were 35 (70.0%). The HEI that were HIV infected despite receiving nevirapine prophylaxis were 5 out of 40(12.5%). CONCLUSION: One in five HEI missed NVP prophylaxis and nearly three quarters of those who missed NVP prophylaxis were HIV infected. Improving uptake of nevirapine by HEI will require interventions that can aid to strengthen PMTCT counselling.

Congenital CMV in the Neonate: A Primer.

Cytomegalovirus, one of the most common congenital viruses in neonates, is represented within the TORCH acronym, which signifies its ability to be transmitted vertically to the fetus during maternal infection. Despite advances in prenatal diagnostics, CMV is still the leading cause of congenital infection in neonates, with a 0.64% prevalence. Additionally, the virus causes the majority of non-genetic hearing deficits, abnormal neurologic development, and other permanent disabilities seen in neonates. This primer describes the presentation, diagnosis, and treatment of congenital infection to benefit providers who work with women during the perinatal period as well as neonates and pediatric patients.

Coincidental discovery of HIV and pregnancy positive status in primary healthcare facilities.

BACKGROUND:  HIV-positive and pregnancy diagnosis is a traumatic, shocking, and distressing experience for women. Adoption of routine HIV counselling and testing in the antenatal programme aimed to increase the uptake and the early diagnosis of HIV among pregnant women to prevent maternal HIV transmission to unborn babies and neonates. OBJECTIVES:  The study aimed to explore the psychological reaction of women coincidentally discovering their HIV-positive status and pregnancy while seeking medical care in primary healthcare facilities in the Tshwane district. METHOD:  Descriptive phenomenology involving a semi-structured in-depth interview was used to collect data. The sample was purposively selected. Twenty-eight women participated in the research project. Face-to-face in-depth audio recorded interviews were used to gain a full understanding of the experiences and feelings of the participants. RESULTS:  Reason for the uptake of pregnancy and HIV testing, reactions upon discovering HIV and pregnancy-positive status, emotions arising from the pregnancy and HIV-positive diagnosis, understanding HIV infection in pregnancy, and transitions to acceptance and coping with the HIV-positive diagnosis were themes that emerged from this study. CONCLUSION:  It is crucial that responsible healthcare workers consider this psychological imbalance during their offering of antenatal and postnatal care services so that the pregnant women living with HIV can accept and cope with the situation.Contribution: This study accounts to support other studies that offer intense counselling for women coincidentally discovering their positive HIV status and pregnancy. It is important to remedy the acceptance of the situation and to promote HIV prevention and family planning for women of childbearing age.

Examining barriers to antiretroviral therapy initiation in infants living with HIV in sub-Saharan Africa despite the availability of point-of-care diagnostic testing: a narrative systematic review.

INTRODUCTION: Antiretroviral therapy (ART) initiation in infants living with HIV before 12 weeks of age can reduce the risk of mortality by 75%. Point-of-care (POC) diagnostic testing is critical for prompt ART initiation; however, despite its availability, rates of ART initiation are still relatively low before 12 weeks of age. This systematic review describes the barriers to ART initiation in infants before 12 weeks of age, despite the availability of POC. METHODS: This systematic review used a narrative synthesis methodology. We searched PubMed and Scopus using search strategies that combined terms of multiple variants of the keywords "early infant initiation on antiretroviral therapy," "barriers" and "sub-Saharan Africa" (initial search 18th January 2023; final search 1st August 2023). We included qualitative, observational and mixed methods studies that reported the influences of early infant initiation on ART. We excluded studies that reported influences on other components of the Prevention of Mother to Child Transmission cascade. Using a deductive approach guided by the updated Consolidated Framework of Implementation Research, we developed descriptive codes and themes around barriers to early infant initiation on ART. We then developed recommendations for interventions for the identified barriers using the action, actor, target and time framework from the codes. RESULTS: Of the 266 abstracts reviewed, 52 full-text papers were examined, of which 12 papers were included. South Africa had most papers from a single country (n = 3) and the most reported study design was retrospective (n = 6). Delays in ART initiation beyond 12 weeks in infants 0-12 months were primarily associated with health facility and maternal factors. The most prominent barriers identified were inadequate resources for POC testing (including human resources, laboratory facilities and patient follow-up). Maternal-related factors, such as limited male involvement and maternal perceptions of treatment and care, were also influential. DISCUSSION: We identified structural barriers to ART initiation at the health system, social and cultural levels. Improvements in the timely allocation of resources for POC testing operations, coupled with interventions addressing social and behavioural barriers among both mothers and healthcare providers, hold a promise for enhancing timely ART initiation in infants. CONCLUSIONS: This paper identifies barriers and proposes strategies for timely ART initiation in infants.

Comprehensive knowledge of mother-to-child HIV/AIDS transmission, prevention, and associated factors among reproductive-age women in East Africa: insights from recent demographic and national health surveys.

BACKGROUND: More than 90% of babies acquire HIV/AIDS through vertical transmission, primarily due to low maternal comprehensive knowledge about Mother-To-Child Transmission (MTCT) of HIV/AIDS and its prevention, which is a cornerstone for eliminating MTCT of HIV/AIDS. However, there are limitations in terms of population data and literature evidence based on recent Demographic and Health Surveys (DHS) reports in East Africa. Therefore, this study aims to assess the comprehensive knowledge and PMTCT of HIV/AIDS among women, as well as the associated factors in East Africa. METHODS: Our data was obtained from the most recent DHS conducted in East African countries between 2011 and 2022. For our research, we included DHS data from ten nations, resulting in a total weighted sample of 133,724 women for our investigation. A generalized linear model (GLM) with a log link and binomial family to directly estimate prevalence ratios (PR) and 95% confidence intervals (CI) for the association between the independent variables, and the outcome variable. Finally, we reported the adjusted prevalence ratios along with their corresponding 95% CIs. Factors with p-values ≤ 0.2 for univariate logistic regression and < 0.05 were considered statistically significant factors of HIV/AIDS knowledge and prevention in the final model. RESULTS: In this study, 59.41% (95% CI: 59.15-59.67) of respondents had a comprehensive knowledge about MTCT of HIV/AIDS and its prevention among reproductive-age women in East Africa. Being in the older age group, better education level, being from a rich household, employment status, having ANC follow up, institutional delivery, and modern contraception usage were associated with higher prevalence ratios of comprehensive knowledge about MTCT of HIV/AIDS and its prevention. However, being single in marital status, rural women, and traditional contraception utilization were associated with lower ratios of comprehensive knowledge about MTCT of HIV/AIDS and its prevention. CONCLUSION: Our findings indicate a significant deficiency in comprehensive knowledge and prevention of HIV/AIDS MTCT among women in East Africa. These results emphasize the need for significant improvements in maternal-related health services. It is crucial to effectively target high-risk populations during interventions, raise awareness about this critical public health issue, and address the catastrophic consequences associated with MTCT. By implementing these measures, we can make substantial progress in reducing the transmission of HIV/AIDS from mother to child and ensuring better health outcomes for both mothers and their children.

Partner-Based HIV Treatment for Seroconcordant Couples Attending Antenatal and Postnatal Care in Rural Mozambique: A Cluster Randomized Controlled Trial.

INTRODUCTION: There is evidence that a supportive male partner facilitates maternal HIV testing during pregnancy, increases maternal antiretroviral therapy initiation and adherence, and increases HIV-free infant survival. Most male partner engagement clinical strategies have focused on increasing uptake of couple-based HIV testing and counseling. We delivered a couple-based care and treatment intervention to improve antiretroviral therapy adherence in expectant couples living with HIV. METHODS: We implemented a cluster randomized controlled trial for seroconcordant couples living with HIV, comparing retention (using a patient's medication possession ratio) in HIV care for a couple-based care and treatment intervention vs. standard of care services in rural Mozambique. The intervention included couple-based treatment, couple-based education and skills building, and couple-peer educator support. RESULTS: We recruited 1080 couples to participate in the study. Using a linear mixed effect model with a random effect for clinic, the intervention had no impact on the medication possession ratio among women at 12 months. However, the intervention increased men's medication ratio by 8.77%. Our unadjusted logistic regression model found the odds of an infant seroconverting in the intervention group was 30% less than in the control group, but the results were not statistically significant. DISCUSSION: Our study found no difference in maternal outcomes by study arm, but our intervention resulted in an improved medication possession ratio among male partners. We provide a community/clinic-based treatment framework that can improve outcomes among male partners. Further work needs to be done to improve social support for pregnant women and to facilitate prevention of vertical transmission to infants among couples living with HIV.

Cardioprotective effects of early versus late initiated antiretroviral treatment in adolescents with perinatal HIV-1 infection.

Whether, and how, cardioprotective effects of antiretroviral treatment (ART) in adolescents with perinatal HIV infection (APHIV) vary with age at treatment initiation is unknown. We used magnetic resonance imaging to compare cardiac status between APHIV initiated on ART at < 5 years of age (early ART, n = 37) and ≥ 5 years of age (delayed ART, n = 34) versus HIV-uninfected peers (n = 21), reporting z-score mean differences adjusted for confounders. Relative to HIV-uninfected adolescents, APHIV with early ART had higher left ventricular (LV) global circumferential strain (GCS) [adjusted mean (95%CI) z-score: 0.53 (0.13, 0.92)] and maximum indexed left atrium volume (LAVi) [adjusted z-score: 0.55 (0.08, 1.02)]. In contrast, APHIV with delayed ART had greater indexed LV end-diastolic volume (LVEDVi) [adjusted z-score: 0.47 (0.09, 0.86)] and extracellular volume fraction [adjusted z-score: 0.79 (0.20, 1.37)], but lower GCS [adjusted z-score: -0.51 (-0.91, -0.10)] than HIV-uninfected peers. APHIV had distinct albeit subclinical cardiac phenotypes depending on ART initiation age. Changes in early ART suggested comparatively worse diastology with preserved systolic function while delayed ART was associated with comparatively increased diffuse fibrosis and LV dilatation with reduced systolic function. The long-term clinical significance of these changes remains to be determined.

'The tablets make a certain noise': uncovering barriers and enablers related to providing PMTCT services to adolescents and young women living with HIV in Zimbabwe.

BACKGROUND: Zimbabwe antenatal HIV prevalence rate is 16.1%. HIV-positive pregnant adolescent girls and young women (AYW) are at high risk to experience perinatal mental health challenges, attributed to a combination of factors including HIV status, stigma and perinatal depression. Perinatal depression and stigma among AYW is understudied in Zimbabwe and may affect short- and long-term health of HIV positive mothers and their children, and can impact treatment adherence. METHODS: Qualitative data was gathered from four focus group discussions with (2 urban and 2 rural) PMTCT providers (N = 17). Focus group discussions were also conducted among AYW clients (N = 20) from two clinics in Mashonaland East. RESULTS: Qualitative analyses identified patterns related to: (1) drop out and loss to follow up, (2) retention and adherence, (3) recurring feelings of internalized stigma; and (4) acceptability of potential MH interventions. MH services are not available and AYW have limited access to adherence counseling (1-2 times at onset). Psychological support was not available at either clinic, despite both providers and clients perceiving high rates of stigma, discrimination, and challenges with disclosure. Challenges related to long waits for ART distribution and gaps in disclosure support emerged as barriers. Providers noted that AYW present as anxious (non-diagnosed), and attribute depression to those clients who are lost to follow up, stating lack of time to screen for MH related issues or actively refer them for services. Challenges related to the ability to provide strong advice and support for disclosure also emerged among providers. CONCLUSIONS: This study can contribute to policy and practice recommendations to better integrate MH into HIV services and develop person-centered service models for HIV positive AYW. HIGHLIGHTSPerinatal adolescents and young women (AYW) living with HIV have gaps in retention and care in the current Zimbabwe PMTCT service model.Mental health stigma must be addressed to integrate mental health into HIV services.HIV providers are aware of the need to provide mental health support to reduce loss to follow-up.Mental health screening and referrals for services are not part of standard care for perinatal HIV positive AYW in Zimbabwe.Linkages between disclosure and AYW mental health was identified as a challenge by HIV providers.Context responsive interventions can support integration of mental health screening, services, and referrals.

Assessment of the effect of pre-conception care on preventing mother-to-child transmission of HIV in Nyeri County.

Introduction: the provision of essential preconception care services for HIV-positive pregnant women is crucial to prevent HIV transmission to infants. This includes pregnancy intention screening services, adequate viral load monitoring and suppression before conception, and necessary nutritional support. In Nyeri County, the prevalence of Mother-to-Child Transmission (MTCT) of HIV is 5.3%, which is higher than the global threshold of 5%. This study aims to evaluate the impact of pre-conception care services in preventing HIV transmission to infants in Nyeri County. The study objectives are to assess the utilization of pre-conception care services among HIV-positive women, specifically focusing on pregnancy intention screening, viral load monitoring and suppression, and access to nutritional assessment services before pregnancy. Additionally, the study aims to investigate the relationship between the provision of pre-conception care services and infant HIV outcomes. Methods: this cross-sectional retrospective descriptive study employed stratified sampling to select eight level 4 and level 5 hospitals in Nyeri County. The target population consisted of HIV-infected women seeking postnatal care in these facilities, with a sample size of 252 women who had HIV-exposed infants under two years old and were receiving post-natal care at the respective hospitals. Sociodemographic characteristics, including age, marital status, and education level, were collected. Data analysis involved both descriptive and inferential statistics. Results: our findings revealed that only 34.2% of HIV-positive women seeking postnatal care had received information or services related to pregnancy intention screening, a crucial aspect of pre-conception care. Almost half (46.4%) of the women who participated in the study had undergone viral load measurements before pregnancy, which is another critical component of preconception care. Additionally, 85.6% of these women had received nutritional services during pregnancy from their healthcare providers. Interestingly, all women who received any pre-conception care services reported that their infants were alive and tested HIV-negative. Conclusion: preconception care is crucial in preventing mother-to-child transmission of HIV. Efforts should be made to ensure that all HIV-infected women planning to conceive have access to preconception care services.

Feeding modalities, HIV transmission and its predictors among HIV-exposed infants visited Gamo and Gofa zones public health facilities, Southern Ethiopia: a retrospective follow up study.

BACKGROUND: Despite the highest (88%) Prevention of Mother-To-Child Transmission (PMTCT) of HIV coverage in Eastern Africa, 50% of new HIV infections in children aged 0-14 years occur in the region. OBJECTIVE: The aim of this study was to assess the feeding modalities, the rate of HIV transmission and its predictors among HIV exposed infants (HIV-EIs) visited Gamo and Gofa Zones public health facilities, Southern Ethiopia from January 2013 to February 2019. METHOD AND MATERIALS: Institution-based retrospective follow up study was employed among 450 HIV-EIs having DNA/PCR test results. All infant-mother pair records in selected health facilities were reviewed using a standard data extraction tool from March to July 2019. HIV transmission probabilities were assessed by Kaplan-Meier time-to-event analysis method and log-rank tests were used to compare the risk among different groups. The Cox-proportional hazards model, adjusted on infant feeding modalities and other co-variants was used to identify predictors of HIV transmission, and statistical significance was declared at a p-value of < 0.05. RESULTS: In total, 383 complete records were analyzed. In the study, 85.6% (95%CI: 81.6%, 89.1%) of HIV-EIs were exclusively breastfed in the first six months. The 18 months probability of infant HIV transmission was 64 (16.7%) (95%CI: 13.1%-20.8%). The risk of HIV-transmission was higher among infants who were delivered at the hospital than health centers/health posts (AHR = 3.07; 95%CI: 1.19, 7.95); discontinued Cotrimoxazole prophylaxis in at least one visit (AHR = 6.32; 95%CI: 3.35, 11.94); did not exclusively breastfeed (AHR = 3.07; 95%CI: 1.72, 5.47) and came from urban areas (AHR = 5.90; 95%CI: 1.40, 24.85). CONCLUSIONS: The study showed that HIV-EIs had a greater rate of 18 months HIV transmission than the national pooled prevalence. The risk of transmission is higher among infants who do not breastfeed exclusively for the first 6 months, and the risk increases with the number of months spent by breastfeeding. Therefore, strengthening counselling on safer feeding options and Cotrimoxazole prophylaxis use; provision of quality PMTCT service with special focus in hospitals and urban residents were recommended.

Magnitude and risk factors of mother-to-child transmission of HIV among HIV-exposed infants after Option B+ implementation in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Mother-to-child transmission (MTCT) of the human immunodeficiency virus (HIV) remains a major public health challenge in Ethiopia. The objective of this review was to assess the pooled magnitude of MTCT of HIV and its risk factors among mother-infant pairs who initiated antiretroviral therapy (ART) after Option B+ in Ethiopia. METHODS: A systematic search of literature from PubMed, Hinari, African Journals Online (AJOL), Science Direct, and Google Scholar databases was conducted from June 11, 2013 to August 1, 2023. The authors used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to guide the article selection process and reporting. Observational studies that reported the magnitude and/or risk factors on MTCT of HIV among mother-infant pairs who initiated ART after the implementation of Option B+ in Ethiopia were included. We applied a random-effect model meta-analysis to estimate the overall pooled magnitude and risk factors of MTCT of HIV. A funnel plot and Egger's regression test were employed to check publication bias, and heterogeneity was assessed using I2 statistics. The protocol was registered in the PROSPERO database with registration ID number CRD42022325938. RESULT: Eighteen published articles on the magnitude of MTCT and 16 published articles on its risk factors were included in this review. The pooled magnitude of MTCT of HIV after the Option B+ program in Ethiopia was 4.05% (95% CI 3.09, 5.01). Mothers who delivered their infants at home [OR: 9.74; (95% CI: 6.89-13.77)], had not been on ART intervention [OR: 19.39; (95% CI: 3.91-96.18)], had poor adherence to ART [OR: 7.47; (95% CI: 3.40-16.45)], initiated ART during pregnancy [OR: 5.09; (95% CI: 1.73-14.97)], had WHO clinical stage 2 and above [OR: 4.95; (95% CI: 1.65-14.88]], had a CD4 count below 350 at enrolment [OR: 5.78; (95% CI: 1.97-16.98], had no or low male partner involvement [OR: 5.92; (95% CI: 3.61-9.71]] and whose partner was not on ART [OR: 8.08; (95% CI: 3.27-19.93]] had higher odds of transmitting HIV to their infants than their counterparts. CONCLUSION: This review showed that the pooled magnitude of MTCT of HIV among mother-infant pairs who initiated ART after the Option B + program in Ethiopia is at the desired target of the WHO, which is less than 5% in breastfeeding women. Home delivery, lack of male partner involvement, advanced HIV-related disease, lack of PMTCT intervention, and poor ARV adherence were significant risk factors for MTCT of HIV in Ethiopia.

COVID-19 therapeutics for the pregnant patient.

SARS-CoV-2 infection can cause severe disease among pregnant persons. Pregnant persons were not included in initial studies of therapeutics for COVID-19, but cumulative experience demonstrates that most are safe for pregnant persons and the fetus, and effective for prevention or treatment of severe COVID-19.
