Prevalence and correlates of prenatal HIV testing among female sex workers in Nigeria.

BACKGROUND: Female sex workers (FSWs) face a significant and persistent risk of contracting HIV. While evidence indicates high rates of pregnancy among FSWs in sub-Saharan Africa, studies on the coverage of HIV testing during pregnancy among them are sparse. The objective of this study was to estimate the prevalence of prenatal HIV testing and determine the associated factors among FSWs in Nigeria. METHODS: This study was a secondary data analysis of the 2020 Integrated Biological & Behavioural Surveillance Survey (IBBSS) among key populations in Nigeria. We performed weighted descriptive statistics and multivariable binary logistic regression to assess the associations between prenatal HIV testing and sociodemographic characteristics, risk behaviours, HIV knowledge and risk awareness, stigma, and access to healthcare. RESULTS: Of the 1598 FSWs included in the study, 71.0% (95%CI = 68.7%-73.1%) had HIV testing during their last pregnancy. In the regression model, tertiary education (aOR = 2.98, 95%CI = 1.48-6.01), consistent condom use (aOR = 1.95, 95%CI = 1.39-2.75), and receipt of antenatal care (aOR = 35.52, 95%CI = 23.40-53.92) were associated with higher odds of prenatal HIV testing. Compared with the South South geopolitical zone, FSW residing in South East (aOR = 3.38, 95%CI = 1.80-6.35), South West (aOR = 2.97, 95%CI = 1.88-4.68), North Central (aOR = 4.43, 95%CI = 2.80-7.01), North East (aOR = 4.22, 95%CI = 1.64-10.34), North West (aOR = 4.40, 95%CI = 2.59-7.48) had higher odds of reporting prenatal HIV testing. However, being a non-brothel-based FSW (aOR = 0.66, 95%CI = 0.47-0.92), and engaging in sex work during pregnancy (aOR = 0.45, 95%CI = 0.31-0.66) were significantly associated with lower odds of prenatal HIV testing. CONCLUSIONS: The prenatal HIV testing among FSWs in this study was suboptimal. The results highlight the need to improve access to antenatal care and implement regional and typology-specific interventions to bridge the gap in prenatal HIV testing among FSWs.

Antiretroviral therapy adherence among peripartum women with HIV in Kenya: an explanatory mixed methods study using dry blood spot measures and narrative interviews.

ABSTRACTAdherence to antiretroviral therapy (ART) remains sub-optimal among pregnant and postpartum women with HIV (PPWH) in high HIV prevalence low resource settings with few effective behavioral interventions. A large body of qualitative literature has established general barriers and facilitators to ART adherence in PPWH at various levels (individual, interpersonal, structural). However, research exploring the underlying behavioral mechanisms of ART adherence in PPWH with objectively verified adherence biomarkers is extremely limited. We conducted 24 in-depth interviews with postpartum women in western Kenya who had linked ART drug concentrations obtained from three dried blood spot samples across the peripartum period. Among PPWH with a low drug concentration (n = 13) compared to those with continuously high drug concentrations (n = 11), distinct themes emerged related to HIV status disclosure, social support, interactions with the health system, and health beliefs. By combining ART biomarkers with patient reported challenges, there is the potential for real-time interventions to support sustained ART adherence among PPWH and improve maternal and infant health outcomes.

Understanding Women's Preferences for Prevention of Mother-to-Child HIV Transmission Services in Kenya.

Background and Objective: Understanding the preferences of women living with HIV (WLH) for the prevention of mother-to-child HIV transmission (PMTCT) services is important to ensure such services are person-centered. Methods: From April to December 2022, we surveyed pregnant and postpartum WLH enrolled at five health facilities in western Kenya to understand their preferences for PMTCT services. WLH were stratified based on the timing of HIV diagnosis: known HIV-positive (KHP; before antenatal clinic [ANC] enrollment), newly HIV-positive (NHP; on/after ANC enrollment). Multivariable logistic regression was used to determine associations between various service preferences and NHP (vs. KHP) status, controlling for age, facility, gravidity, retention status, and pregnancy status. Results: Among 250 participants (median age 31 years, 31% NHP, 69% KHP), 93% preferred integrated versus non-integrated HIV and maternal-child health (MCH) services; 37% preferred male partners attend at least one ANC appointment (vs. no attendance/no preference); 54% preferred support groups (vs. no groups; 96% preferred facility - over community-based groups); and, preferences for groups was lower among NHP (42%) versus KHP (60%). NHP had lower odds of preferring support groups versus KHP (aOR 0.45, 95% CI 0.25-0.82), but not the other services. Conclusion and Global Health Implications: Integrated services were highly preferred by WLH, supporting the current PMTCT service model in Kenya. Further research is needed to explore the implementation of facility-based support groups for WLH as well as the reasons underlying women's preferences.

Resistance Mutation Patterns among HIV-1-Infected Children and Features of the Program for Prevention of Mother-to-Child Transmission in Vietnam's Central Highlands and Southern Regions, 2017-2021.

The Vietnam Ministry of Health (MOH) has intensified efforts in its aim to eliminate AIDS by 2030. Expanding the program for prevention of mother-to-child transmission (PMTCT) is a significant step towards achieving this goal. However, there are still HIV-exposed children who do not have access to PMTCT services, and some who have participated in the program but still contracted HIV. This study focused on assessing the prevalence and profile of HIV mutations among children under 18 months of age who had recently tested positive for HIV, while gaining insights into the implementation of early infant diagnostic (EID) tests. Between 2017 and 2021, 3.43% of 5854 collected dry blood spot (DBS) specimens from Vietnam's Central and Southern regions showed positive EID results. This study identified a high prevalence of resistance mutations in children, totaling 62.9% (95% CI: 53.5-72.3). The highest prevalence of mutations was observed for NNRTIs, with 57.1% (95% CI: 47.5-66.8). Common mutations included Y181C and K103N (NNRTI resistance), M184I/V (NRTI resistance), and no major mutations for PI. The percentage of children with any resistance mutation was significantly higher among those who received PMTCT interventions (69.2%; 95% CI: 50.5-92.6%) compared with those without PMTCT (45.0%; 95% CI: 26.7-71.1%) with χ2 = 6.06, p = 0.0138, and OR = 2.75 (95% CI: 1.13-6.74). Mutation profiles revealed that polymorphic mutations could be present regardless of whether PMTCT interventions were implemented or not. However, non-polymorphic drug resistance mutations were predominantly observed in children who received PMTCT measures. Regarding PMTCT program characteristics, this study highlights the issue of late access to HIV testing for both mothers and their infected children. Statistical differences were observed between PMTCT and non-PMTCT children. The proportion of late detection of HIV infection and breastfeeding rates were significantly higher among non-PMTCT children (p < 0.05). Comparative analysis between children with low viral load (≤200 copies/mL) and high viral load (>200 copies/mL) showed significant differences between the mothers' current ART regimens (p = 0.029) and the ARV prophylaxis regimen for children (p = 0.016). These findings emphasize the need for comprehensive surveillance to assess the effectiveness of the PMTCT program, including potential transmission of HIV drug-resistance mutations from mothers to children in Vietnam.

Hepatitis B Virus Prevalence and Transmission in the Households of Pregnant Women in Kinshasa, Democratic Republic of Congo.

Background: The World Health Organization Africa region has high regional hepatitis B virus (HBV) prevalence, and evidence suggests more frequent horizontal HBV transmission than other regions. Context-specific epidemiological studies are needed to inform additional HBV prevention measures. Methods: In the cross-sectional Horizontal and Vertical Transmission of Hepatitis B (HOVER-HBV) study, we introduced HBV surface antigen (HBsAg) screening alongside existing HIV screening as part of routine antenatal care in high-volume maternity clinics in Kinshasa, Democratic Republic of Congo. We recruited households of pregnant women ("index mothers") who were HBsAg-positive and HBsAg-negative, defining households as index-positive and index-negative, respectively. Household members underwent HBsAg testing and an epidemiological survey. We evaluated HBsAg prevalence and potential transmission correlates. Results: We enrolled 1006 participants from 200 households (100 index-positive, 100 index-negative) across Kinshasa. HBsAg-positivity prevalence was more than twice as high in index-positive households (5.0% [95% confidence interval {CI}, 2.8%-7.1%]) as in index-negative households (1.9% [95% CI, .6%-3.2%]). HBsAg-positivity prevalence was 3.3 (95% CI, .9-11.8) times as high among direct offspring in index-positive versus index-negative households. Factors associated with HBsAg positivity included older age, marriage, and having multiple recent partners or any new sexual partners among index mothers; and older age, lower household wealth, sharing nail clippers, and using street salons among offspring in index-positive households. Conclusions: Vertical and horizontal HBV transmission within households is ongoing in Kinshasa. Factors associated with infection reveal opportunities for HBV prevention efforts, including perinatal prevention, protection during sexual contact, and sanitation of shared personal items.

Efficacy of mobile phone intervention to increase male partner antenatal care attendance for HIV testing in Moshi municipal, Tanzania: a randomized controlled trial.

BACKGROUND: HIV partner counselling and testing in antenatal care (ANC) is a crucial strategy to raise the number of males who know their HIV status. However, in many settings like Tanzania, male involvement in antenatal care remains low, and there is a definite need for innovative strategies to increase male partner involvement. This study was designed to evaluate the efficacy of mobile phone intervention increase male partner ANC attendance for HIV testing in Moshi municipal, Tanzania. METHODS: Between April and July 2022, we enrolled pregnant women presenting to a first ANC visit at Majengo and St. Joseph reproductive health facilities without their male partners. Eligible pregnant women were randomly assigned to invitation of their male partners either via phone calls, text messages from clinic staff and verbal invites from pregnant partners (intervention arm) or verbal invites only from the pregnant partners (control arm). Neither healthcare provider nor participant were blinded. The primary outcome was the proportion of male partners who attended ANC with their pregnant partners during a follow-up period of two consecutive visits. The secondary outcome measure was HIV testing among male partners following the invitation. Participants were analyzed as originally assigned (intention to treat). RESULTS: A total of 350 pregnant women presenting to ANC for the first time were enrolled, with 175 women enrolled in each arm. The efficacy of male attendance with their pregnant women following the invitations was 83.4% (147/175) in the intervention arm and 46.3% (81/175) in the control arm. Overall, the results suggest a positive and statistically significant average treatment effect among men who received mobile phone intervention on ANC attendance. For the secondary outcome, the percent of male partners who accepted HIV counselling and testing was 99.3% (146/147) in the intervention arm and 93.8% (76/81) in the control arm. Married men were having higher odds of ANC attendance compared with single men (aOR:6.40(3.26-12.56), Males with multigravida women were having lower odds of ANC attendance compared with primigravida women (aOR:0.17(0.09-0.33). CONCLUSION: The study demonstrates that supplementing verbal invitations with mobile phone calls and text messages from clinic staff can significantly increase male partner ANC attendance and HIV testing. This combined approach is recommended in improving ANC attendance and HIV testing of male partners who do not accompany their pregnant partners to antenatal clinics in the first visits.

HIV seroconversion and associated factors among seronegative pregnant women attending ANC in Ethiopia: an institution-based cross-sectional study.

Background: In countries with limited resources, including Ethiopia, HIV is diagnosed using a rapid serological test, which does not detect the infection during the window period. Pregnant women who test negative for HIV on the first test may seroconvert throughout pregnancy. Women who are seroconverted during pregnancy may not have received interventions, as they are considered HIV-negative unless they are retested for HIV at the end of their pregnancy. Due to limited data on HIV seroconversion, this study aimed to measure the extent of HIV seroconversion and to identify associated factors among seronegative pregnant women attending ANC in Ethiopia. Methods: Institution-based cross-sectional study was conducted among HIV-negative pregnant women attending the ANC in Ethiopia between June and July 2020. Socio-demographic, clinical, and behavioral data were collected through face-to-face questionnaires and participants' records review. HIV retesting was performed to determine the current HIV status of pregnant women. The data collected were entered into Epi data version 4.4.1 and were exported and analyzed by SPSS version 25. A p-value < 0.25 in the bivariate analysis was entered into multivariable logistic regression analysis and a p-value of < 0.05 was considered statistically significant. Result: Of the 494 pregnant women who tested negative for HIV on their first ANC test, six (1.2%) tested positive on repeat testing. Upon multivariable logistic regression, pregnant women who have had a reported history of sexually transmitted infections [AOR = 7.98; 95% CI (1.21, 52.82)], participants' partners reported travel history for work frequently [AOR = 6.00; 95% CI (1.09, 32.99)], and sexually abused pregnant women [AOR = 7.82; 95% CI (1.194, 51.24)] were significantly associated with HIV seroconversion. Conclusion: The seroconversion rate in this study indicates that pregnant women who are HIV-negative in early pregnancy are at an ongoing risk of seroconversion throughout their pregnancy. Thus, this study highlights the benefit of a repeat HIV testing strategy in late pregnancy, particularly when the risk of seroconversion or new infection cannot be convincingly excluded. Therefore, repeated testing of HIV-negative pregnant women in late pregnancy provides an opportunity to detect seroconverted pregnant women to enable the timely use of ART to prevent mother-to-child transmission of HIV infection.

Efficacy of antiviral therapy for the prevention of mother-to-child transmission of hepatitis B virus and the risk of postpartum hepatitis flare after discontinuation of antiviral therapy.

The use of nucleos(t)ide analogs (NAs) is recommended for mothers with a high viral load of hepatitis B virus (HBV) during the second or third trimester of pregnancy. However, postpartum hepatitis flares can occur in some cases. We examined the efficacy of NA administration for the prevention of mother-to-child transmission of hepatitis B virus, and evaluated the risk of postpartum hepatitis flares in mothers after NA discontinuation. Nine pregnant women with a high viral load (HBV DNA ≥5.3 log IU/mL) received tenofovir disoproxil fumarate (TDF) at approximately 28 weeks of gestation, and TDF was discontinued at 4-10 weeks after delivery. We evaluated the virological and biochemical parameters in mothers after TDF discontinuation. Hepatitis flares in mothers were defined as alanine transaminase level ≥60 U/L. None of the infants developed any congenital anomaly or acquired HBV infection during infancy. Hepatitis flares occurred within 6 months after TDF discontinuation in five of seven cases, whereas two cases were lost to follow-up. Furthermore, three cases required the resumption of NA use. NA administration was highly effective against mother-to-child-transmission of HBV in pregnant women with high HBV DNA levels. However, hepatitis flares were commonly observed after NA discontinuation in the postpartum period. Patients should be followed up carefully after NA discontinuation, and NA resumption should be considered based on a comprehensive assessment of virological and biochemical parameters.

Effects of the COVID-19 pandemic on early infant diagnosis of HIV in Cape Town, South Africa.

Background: In South Africa, infants who are HIV-exposed are tested for HIV at birth and 10 weeks of age. The COVID-19 pandemic lockdown restrictions resulted in reduced access to healthcare services and uncertain impact on early infant HIV testing. Objectives: To describe the effects of the COVID-19 pandemic lockdown restrictions on early infant HIV testing and diagnosis in Cape Town, South Africa. Method: This retrospective cohort study compares HIV-exposed infants born during the first COVID-19 pandemic lockdown (2020) to those born in the same period the year before (2019). Laboratory and other data were abstracted from the Provincial Health Data Centre. Results: A total of 2888 infants were included: 1474 born in 2020 and 1413 in 2019. Compared to 2019, there was an increase in the 10-week HIV polymerase chain reaction (PCR) uptake in 2020 (71% vs. 60%, P < 0.001). There was also an increase in the proportion of infants who demised without 10-week testing or were lost to follow-up in 2020 compared to 2019 (8% vs. 5%, P = 0.017). Differences detected in birth HIV PCR positivity rates between the two groups (1.1% vs. 0.5%, P = 0.17) did not reach statistical significance; however, a significant increase in vertical transmission of HIV by 10 weeks old was found in the 2020 cohort (1.2% vs. 0.5%. P = 0.046). Conclusion: Vertical transmission of HIV at 10 weeks increased in the Cape Town Metropolitan during the initial COVID-19 lockdown. There was also an increase in the proportion of deaths without testing by 10 weeks in the 2020 group.

Effectiveness of telemedicine for the prevention of mother-to-child transmission of HIV in low-income and middle-income countries: a systematic review and meta-analysis.

OBJECTIVES: We aimed to estimate the effectiveness of telemedicine for the prevention of mother-to-child transmission (PMTCT) program of HIV in low- and middle-income countries (LMICs). METHODS: We did a systematic literature search of 15 databases for articles published from database inception to October 26, 2022, and performed meta-analyses to estimate the pooled risk ratio of intervention effect (RR) and its 95% confidence interval (CI). We used subgroup analyses and meta-regressions to explore variation in the RRs. Funnel plots and Egger regression tests were also performed to assess publication bias. RESULTS: Seventeen studies were included in the systematic review, with a total sample size of 9118 participants. We found that telemedicine was beneficial for early infant diagnosis (EID) in the sixth week (RR 1.04 [95% CI 1.00-1.09]), exclusive breastfeeding (RR 1.12 [95% CI 1.01-1.24]) and PMTCT retention (RR 1.34 [95% CI 1.16-1.55]). However, we did not find a significant effect of telemedicine on infant prophylaxis, HIV transmission, and ART adherence. Besides, the heterogeneity of ART adherence was associated with enrollment time, while retention was related to ART initiation. CONCLUSIONS: Our meta-analysis demonstrated the benefits of telemedicine in improving PMTCT, especially for EID, exclusive breastfeeding, and PMTCT retention.

Effects of Maternal Health During Pregnancy and Child Immunization on Mother-to-Child Transmission of Hepatitis B Virus: A Multicentre, Large-Sample Study in Southeast China.

Purpose: High hepatitis B infection rates in China are a major public health issue, and mother-to-child transmission (MTCT) is a significant risk factor. Patients and Methods: This study was conducted with a prospective multicentre design from January 2021 to December 2022 in 245 hospitals providing midwifery services in southeastern China. The participants were pregnant women who were positive for hepatitis B surface antigen (HBs Ag) and their children. The HBs Ag concentration was tested in children aged 8-12 months. The odds ratio for each risk factor was calculated by logistic regression analysis, and the decision tree model was used. Results: A total of 5369 children born to hepatitis B-infected mothers between 8 and 12 months of age were enrolled, among whom 81 (1.51%) were positive for HBsAg. The risk factors for hepatitis B infection in 5369 children under one-year-old were a high intrauterine hepatitis B exposure level, a history of hepatitis B immunoglobulin (HBIG) delay beyond 12 hours after birth, and lack of full hepatitis B vaccine (HepB), with risks of 3.356 (1.223~9.209), 5.691 (1.931~16.773), and 5.137 (2.265~11.650), respectively. The discrimination accuracy of the decision tree was 98.5%. The risk factors for hepatitis B infection in 4542 children under one year old with high exposure risk were nonstandard treatment by the mother during pregnancy, HBIG delay beyond 12 hours after birth, and no complete HepB administration, with risks of 2.925 (1.063-8.047), 5.354 (1.806-15.871) and 5.147 (2.258-11.733), respectively. The discrimination accuracy of the decision tree was 98.3%. Conclusion: To prevent mother-to-child transmission of hepatitis B, it is necessary to standardize the treatment of pregnant women with a high exposure risk of hepatitis B, implement combined vaccination within 12 hours of birth, and standardise the full course of HepB.

Correlates of early breastfeeding cessation and breastmilk expression in Uganda: a case-control study.

OBJECTIVE: To identify the correlates of early breastfeeding (BF) cessation and breastmilk expression (BE) among mothers 12 months after childbirth. METHODS: We used a case-control study design to compare characteristics between mothers who stopped BF and expressed breastmilk 12 months after childbirth in Uganda. BF practices were determined in 12-month follow-up interviews using an adapted World Health Organization infant feeding questionnaire. Univariate and bivariate logistic regression models identified correlates of early BF cessation and BE as distinct but related outcomes. RESULTS: The odds of early BF cessation were higher among mothers who expressed breastmilk irrespective of maternal age (adjusted odds ratio: 2.82; 95% confidence interval: 1.39, 5.68). Mothers who stopped BF and did not express breastmilk were more likely to be older than those who continued BF and did not express breastmilk during the first 12 postpartum months. CONCLUSION: Mothers living with human immunodeficiency virus infection have disproportionately high odds of early BF cessation that may contribute to disparities in child health outcomes. Promotion of safe BF practices coupled with family and social support could be a viable preventive strategy for attenuating such disparities, especially among young mothers at risk of early BF cessation.

Assessing COVID-related concerns and their impact on antenatal and delivery care among pregnant women living with HIV in Kenya: a brief report.

BACKGROUND: Some studies indicate that pregnant Kenyan women were concerned about Coronavirus disease 2019 (COVID-19) exposure during maternity care. We assessed concern regarding COVID-19 exposure and any impact on antenatal care (ANC) enrollment and/or hospital delivery among pregnant women living with human immunodeficiency virus (HIV) in Kenya. METHODS: Data were collected from 1,478 pregnant women living with HIV enrolled in prevention of mother to child transmission of HIV (PMTCT) care at 12 Kenyan hospitals from October 2020 to July 2022. Surveys were conducted when women first presented for PMTCT services at the study hospital and asked demographic questions as well as items related to concerns about COVID-19. A 5-point Likert scale (strongly disagree to strongly agree) assessed concerns about COVID-19 exposure and travel challenges. Gestational age at PMTCT enrollment, number of ANC appointments attended, and delivery location were compared among women who expressed COVID-19 concerns and those who did not. RESULTS: Few women reported delaying antenatal care (4.7%), attending fewer antenatal care appointments (5.0%), or having concerns about a hospital-based delivery (7.7%) because of COVID-19. More (25.8%) reported travel challenges because of COVID-19. There were no significant differences in gestational age at enrollment, number of ANC appointments, or rates of hospital-based delivery between women with concerns about COVID-19 and those without, CONCLUSION: Few pregnant women living with HIV expressed concerns about COVID-19 exposure in the context of routine ANC or delivery care. Women with and without concerns had similar care seeking behaviors. The recognized importance of routine ANC care and facility-based deliveries may have contributed to these positive pregnancy indicators, even among women who worried about COVID-19 exposure.

Money, chores and emotional support: Kenyan and Zambian fathers' perceptions of male partner involvement in maternal and infant health within the context of HIV.

In sub-Saharan Africa, involving male partners in the prevention of mother-to-child transmission of HIV improves maternal and infant outcomes. Male involvement is typically conceptualised as male partners attending antenatal care, which is difficult for many men. Little is known about how men view their involvement in family health within the context of HIV, particularly outside of clinic attendance. Through interviews with 35 male partners of pregnant or postpartum women living with HIV in Kenya and Zambia, this study elicited perceptions of male involvement in maternal and infant health in families affected by HIV. Men supported the importance of clinic attendance but reported conflicts with the need to work and fulfil their role as the family's financial provider. Providing money for necessities was deemed more critical for their family's health than clinic attendance. Men's involvement was conveyed through various other supportive actions, including helping with household chores and providing emotional support (showing love and reducing women's stress). Future strategies to promote male partner involvement in the prevention of mother-to-child transmission of HIV and maternal and child health should build upon the actions men view as most meaningful to promote their family's health within their real-world life circumstances and cultural context, particularly their role as financial providers.

Availability and readiness of the health facilities to provide HIV counseling and testing and prevention of mother-to-child transmission services in Burkina Faso: a trend analysis from 2012 to 2018.

BACKGROUND: Provider-Initiated HIV Testing and Counseling (PITC) and Prevention of Mother-To-Child Transmission (PMTCT) are key services for achieving the goal of complete elimination of HIV. However, there is limited evidence on the ability of health facilities to provide these services in Burkina Faso. Therefore, we aimed to assess the trends and disparities in the availability and readiness of health facilities to provide PITC and PMTCT services in Burkina Faso between 2012 and 2018. METHODS: We performed a secondary analysis of facility-level data from the World Health Organization's Service Availability and Readiness Assessment (SARA) surveys conducted in 2012, 2014, 2016, and 2018 in Burkina Faso. The availability and readiness of health facilities were assessed using SARA's manual, and linear regressions were used to examine trends. RESULTS: Between 2012 and 2018, the mean proportion of health facilities providing PITC services increased, but not significantly, from 82.9% to 83.4% (p = 0.11), with the mean readiness index significantly decreasing from 71.5% to 65.4% (p < 0.001). This decrease concerned the staff and guidelines (73.8% to 50.5%; p < 0.001), equipment (79.0% to 77.4%; p < 0.001), and medicines and commodities (54.2% to 45.2%; p < 0.001) domains. Regarding the PMTCT services, the mean proportion of health facilities globally providing the service significantly decreased from 83.7% in 2012 to 67.7% (p = 0.030) in 2018, and the mean readiness significantly decreased from 53.2% in 2012 to 50.9% in 2018 (p = 0.004). This decreasing trend was related to the staff and training (80.3% to 57.6%; p < 0.001) and medicines and commodities (9.2% to 6.5%; p < 0.001) domains. The global significant negative trend of readiness was mainly observed at the primary level of healthcare (52.7% to 49.4%; p = 0.030). Four regions experienced a significant decrease in the readiness index of health facilities to provide PMTCT services: Cascades, Centre, Centre-Sud, and Sud-Ouest, while Haut-Bassins and Nord regions showed increasing trends. CONCLUSION: Availability and readiness of health facilities to provide PITC and PMTCT remain suboptimal in Burkina Faso. Actions to strengthen the skills of professionals and enhance the availability of medicines and commodities while focusing more on health regions with significant decreasing trends are urgently needed to improve the quality of services for HIV.

Midwives' perceptions of and attitudes towards prevention of mother-to-child-transmission of HIV.

BACKGROUND: Prevention of mother-to-child transmission (PMTCT) of HIV services has become an integral part of antenatal services. Prevention of mother-to-child transmission was introduced in all the regions of Ghana, but mother-to-child transmission (MTCT) continued to increase. OBJECTIVES: To explore and describe midwives' perceptions and attitudes towards PMTCT of HIV services. METHOD: Quantitative research approach and descriptive cross-sectional design were used. The population includes all midwives between the ages of 21 and 60 years who work in antenatal care (ANC) clinics in 11 district hospitals in the Central Region of Ghana where the study was conducted. Forty-eight midwives were interviewed using a census sample process. Data were analysed using the Statistical Package for the Social Sciences version 21. Correlation analysis was performed to find the relationships between the attitudes and the perceptions of the midwives on PMTCT of HIV services. RESULTS: Seventy percent of midwives had positive perceptions of PMTCT of HIV services and 85% had positive attitudes towards the provision of PMTCT of HIV services. Midwives were screening all pregnant women who visited the ANCs and referring those who tested positive to other institutions where they can be monitored. Some of the concerns considered were views on retesting HIV-infected pregnant women throughout their pregnancy. There was a positive correlation between attitudes and perceptions of midwives on PMTCT of HIV services. CONCLUSION: Midwives had positive perceptions and positive attitudes towards the PMTCT of HIV services that they were providing to antenatal attendees. Also, as the attitudes of the midwives towards PMTCT of HIV services improved, their perceptions of PMTCT services also improved.Contribution: Decentralisation of PMTCT of HIV services to community-based health facilities is appropriate to enable sub-district health facilities to test for HIV and provide counselling services to pregnant women.

Resistance rates among antiretroviral regimens in pregnant people living with HIV.

OBJECTIVES: To update nucleoside reverse transcriptase inhibitor (NRTI), nonnucleoside reverse transcriptase inhibitor (NNRTI) and protease inhibitor (PI) resistance rates and describe the frequency of HIV subtypes in a cohort of pregnant people living with HIV (PPLH) at a national Prevention of Mother-To-Child HIV Transmission (PMTCT) centre. METHODS: We evaluated genotypic resistance among PPLH during prenatal care who were antiretroviral therapy-naïve or experienced. We determined mutations by the Surveillance of Drug Resistance Mutations (SDRM) dataset and also focused on studying participants with intermediate or high resistance defined through the Stanford score. RESULTS: From 2018 to 2021, 1170 PPLH received prenatal care at the centre and 550 were genotyped. Among the 295 SDRMs, with respect to NRTI resistance mutations, there were 27/295 (9.2%) M184V/I, 14/295 (4.7%) T215Y/C/D/E/F/V/I/S and 12/295 (4.1%) M41L. For NNRTI, there were 75/295 (25.4%) K103N, 18/295 (6.1%) M230L and 14/295 (4.7%) G190A/E/S mutations. For PI, the most frequent mutations were 13/295 (4.4%) V82A/S/F/T, 12/295 (4.1%) M46I/L and 10/295 (3.4%) D30N. Based on the Stanford score, 36/224 (16%) naïve participants had one or more antiretroviral resistance mutations, 81% of whom had NNRTI resistance. In the treatment-experience group, 108/326 (33%) had one or more mutations, 91% of whom had NNRTI resistance. The most frequent HIV subtype was B (82.5%). CONCLUSIONS: Our findings suggest that continuous surveys of HIV genotype appear to be important tools to map the distribution and evolution of HIV subtypes and resistance to provide information to support treatment policies. Furthermore, concerns about the use of rilpivirine-containing regimens underscore the importance of resistance surveillance.

The effects of revised peer-counselor support on the PMTCT cascade of care: results from a cluster-randomized trial in Kenya (the EMMA study).

BACKGROUND: This study evaluated the effect of revisions to existing peer-counselor services, called Mentor Mothers (MM), at maternal and child health clinics on medication adherence for women living with HIV (WLWH) in Kenya and on early infant HIV testing. METHODS: The Enhanced Mentor Mother Program study was a 12-site, two-arm cluster-randomized trial enrolling pregnant WLWH from March 2017 to June 2018 (with data collection through September 2020). Six clinics were randomized to continued MM-supported standard care (SC). Six clinics were randomized to the intervention arm (INT = SC plus revised MM services to include more one-on-one interactions). Primary outcomes for mothers were defined as: (PO1) the proportion of days covered (PDC) with antiretroviral therapy (ART) ≥ 0.90 during the last 24-weeks of pregnancy; and (PO2) ≥ 0.90 PDC during the first 24-weeks postpartum. Secondary outcomes were infant HIV testing according to national guidelines (at 6, 24, and 48 weeks). Crude and adjusted risk differences between study arms are reported. RESULTS: We enrolled 363 pregnant WLHV. After excluding known transfers and subjects with incomplete data extraction, data were analyzed for 309 WLWH (151 SC, 158 INT). A small share achieved high PDC during the prenatal and postnatal periods (0.33 SC/0.24 INT achieved PO1; 0.30 SC/0.31 INT achieved PO2; crude or adjusted risk differences were not statistically significant). In addition, ~ 75% in both study arms completed viral load testing during year two after enrollment, with > 90% suppressed in both arms. For infants, ≥ 90% in both arms had at least one HIV test through study follow up (76 weeks) but testing on schedule according to PMTCT guidelines was uncommon. CONCLUSIONS: While national guidelines in Kenya recommended that all HIV-infected pregnant women take a daily antiretroviral regimen for life following a HIV diagnosis, results presented here indicate that a minor share achieved high medication coverage during the prenatal and postnatal periods analyzed. In addition, adjustments to Mentor-Mother services showed no improvement in study outcomes. The lack of effect for this behavioral intervention is relatively consistent with the existing literature to improve mother-infant outcomes along the PMTCT care cascade.

Factors associated with lifetime HIV testing among women in four Southeast Asian countries: Evidence from the demographic and health surveys.

BACKGROUND: Southeast Asian countries have been trying to increase HIV testing coverage of women since awareness of HIV status is essential to eliminate mother-to-child transmission of HIV. This study determined factors related to lifetime HIV testing uptake among women aged 15-49 years in four Southeast Asian countries: Myanmar, Cambodia, the Philippines and Timor-Leste. METHODS: This study used cross-sectional data from the 2015-16 Myanmar Demographic and Health Survey (DHS), the 2014 Cambodia DHS, the 2017 Philippines National DHS and the 2016 Timor-Leste DHS. We conducted multivariable logistic regression analyses to identify factors associated with lifetime HIV testing among women aged 15-49 years who completed the surveys in each country and ran a fixed effects logistic regression model using pooled data. RESULTS: The proportions of lifetime HIV testing uptake among women aged 15-49 years were 42.1% in Cambodia, 19.5% in Myanmar, 4.6% in the Philippines, and 3.7% in Timor-Leste. Marital status, age, education, and wealth were significantly associated with lifetime HIV testing uptake among women in all four countries. Other factors (e.g., comprehensive knowledge of HIV, rural/urban residence, positive attitudes towards negotiation for safer sex) were also significant determinants of HIV testing uptake among women in some of these countries. CONCLUSIONS: A multi-sectoral collaboration of related sectors and organizations is necessary to increase access to HIV testing and HIV knowledge of women to overcome the barriers to HIV testing. It is critical to make HIV testing services available and accessible to women, especially in rural areas.

Now is the Time to Scale Up Birth-Dose Hepatitis B Vaccine in Low- and Middle-Income Countries.

Fewer than half of the world's infants have access to the birth dose of hepatitis B vaccine (HBV), which prevents mother-to-child transmission of HBV and subsequent liver cancer. Now is the time to expand access for infants born in low-resource settings.
