RESUMO

BACKGROUND: The World Health Organization (WHO) recommends that women with HIV breastfeed for a minimum of one year. In contrast, across high-income countries, HIV and infant-feeding guidelines recommend exclusive formula feeding if parents want to avoid all risk of postpartum transmission. However, recently these guidelines (including in the United Kingdom (UK)) increasingly state that individuals with HIV should be supported to breast/chest feed if they meet certain criteria; such as an undetectable maternal HIV viral load and consent to additional clinical monitoring. Between 600 and 800 pregnancies are reported annually in women with HIV in the UK, with low rates of vertical transmission (0.22%). Informed infant-feeding decision-making requires clinical support. Currently, little research addresses how individuals with HIV in high-income countries navigate infant-feeding decisions with their clinical teams and familial and social networks, and the resources needed to reach an informed decision. METHODS: Semi-structured remote interviews were conducted between April 2021 - January 2022 with UK-based individuals with a confirmed HIV diagnosis who were pregnant or one-year postpartum. Using purposive sampling, pregnant and postpartum participants were recruited through NHS HIV clinics, community-based organisations and snowballing. Data were analysed thematically and organised using NVivo 12. RESULTS: Of the 36 cisgender women interviewed, 28 were postpartum. The majority were of Black African descent (n = 22) and born outside the UK. The majority of postpartum women had chosen to formula feed. Women's decision-making regarding infant-feeding was determined by (1) information and support; (2) practicalities of implementing medical guidance; (3) social implications of infant-feeding decisions. CONCLUSION: The evolution of UK HIV and infant-feeding guidelines are not reflected in the experiences of women living with HIV. Clinicians' emphasis on reducing the risk of vertical transmission, without adequately considering personal, social and financial concerns, prevents women from making fully informed infant-feeding decisions. For some, seeking advice beyond their immediate clinical team was key to feeling empowered in their decision. The significant informational and support need among women with HIV around their infant-feeding options must be addressed. Furthermore, training for and communication by healthcare professionals supporting women with HIV is essential if women are to make fully informed decisions.

RESUMO

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.

RESUMO

Although a combination of immunoprophylaxis and antiviral therapy can effectively prevent mother-to-child transmission (MTCT) of hepatitis B virus (HBV), a considerable number of infants born to highly viremic mothers still develop occult HBV infection (OBI). To uncover the virological factor and risk predictor for OBI in infants, we found that the diversity and complexity of maternal HBV quasispecies in the case group were lower than those in the control group. Mutations with significant differences between the two groups were most enriched in the NTCPbd and PreC regions. Genetic distance at the amino-acid level of the PreC region, especially the combination of three amino-acid mutations in the PreC region, could strongly predict the risk of OBI in infants. HBV quasispecies in OBI infants were highly complex, and the non-synonymous substitutions were mainly found in the RT and HBsAg regions. The sK47E (rtQ55R) and sP49L mutations in OBI infants might contribute to OBI through inhibiting the production of HBV DNA and HBsAg, respectively. This study found the potential virological factors and risk predictors for OBI in infants born to highly viremic mothers, which might be helpful for controlling OBI in infants.

RESUMO

Background & Aims: In 2020, the World Health Organization (WHO) recommended peripartum antiviral prophylaxis (PAP) for pregnant women infected with hepatitis B virus (HBV) with high viremia (≥200,000 IU/ml). Hepatitis B e antigen (HBeAg) was also recommended as an alternative when HBV DNA is unavailable. To inform policymaking and guide the implementation of prevention of mother-to-child transmission strategies, we conducted a systematic review and meta-analysis to estimate the proportion of HBV-infected pregnant women eligible for PAP at global and regional levels. Methods: We searched PubMed, EMBASE, Scopus, and CENTRAL for studies involving HBV-infected pregnant women. We extracted proportions of women with high viremia (≥200,000 IU/ml), proportions of women with positive HBeAg, proportions of women cross-stratified based on HBV DNA and HBeAg, and the risk of child infection in these maternal groups. Proportions were pooled using random-effects meta-analysis. Results: Of 6,999 articles, 131 studies involving 71,712 HBV-infected pregnant women were included. The number of studies per WHO region was 66 (Western Pacific), 21 (Europe), 17 (Africa), 11 (Americas), nine (Eastern Mediterranean), and seven (South-East Asia). The overall pooled proportion of high viremia was 21.27% (95% CI 17.77-25.26%), with significant regional variation: Western Pacific (31.56%), Americas (23.06%), Southeast Asia (15.62%), Africa (12.45%), Europe (9.98%), and Eastern Mediterranean (7.81%). HBeAg positivity showed similar regional variation. After cross-stratification, the proportions of high viremia and positive HBeAg, high viremia and negative HBeAg, low viremia and positive HBeAg, and low viremia and negative HBeAg were 15.24% (95% CI 11.12-20.53%), 2.70% (95% CI 1.88-3.86%), 3.69% (95% CI 2.86-4.75%), and 75.59% (95% CI 69.15-81.05%), respectively. The corresponding risks of child infection following birth dose vaccination without immune globulin and PAP were 14.86% (95% CI 8.43-24.88%), 6.94% (95% CI 2.92-15.62%), 7.14% (95% CI 1.00-37.03%), and 0.14% (95% CI 0.02-1.00%). Conclusions: Approximately 20% of HBV-infected pregnant women are eligible for PAP. Given significant regional variations, each country should tailor strategies for HBsAg screening, risk stratification, and PAP in routine antenatal care. Impact and implications: In 2020, the WHO recommended that pregnant women who test positive for the hepatitis B surface antigen (HBsAg) undergo HBV DNA testing or HBeAg and those with high viremia (≥200,000 IU/ml) or positive HBeAg receive PAP. To effectively implement new HBV PMTCT interventions and integrate HBV screening, risk stratification, and antiviral prophylaxis into routine antenatal care services, estimating the proportion of HBV-infected pregnant women eligible for PAP is critical. In this systematic review and meta-analysis, we found that approximately one-fifth of HBV-infected pregnant women are eligible for PAP based on HBV DNA testing, and a similar proportion is eligible based on HBeAg testing. Owing to substantial regional variations in eligibility proportions and the availability and costs of different tests, it is vital for each country to optimize strategies that integrate HBV screening, risk stratification, and PAP into routine antenatal care services. Systematic review registration: This study was registered with PROSPERO (Protocol No: CRD42021266545).

RESUMO

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.

RESUMO

BACKGROUND: Birth-dose (Hep-BD) followed by three additional doses (Hep-B3) of hepatitis B virus (HBV) vaccine are key to eliminating HBV by 2030. Unfortunately, Hep-BD and Hep-B3 coverage in our country is poor. AIM: To studied the parent's knowledge and awareness about HBV infection, its prevention, consequences and vaccination. METHODS: Parents of 6 months to 8 years old children were interviewed to assess their knowledge & awareness about hepatitis B, its transmission, prevention, illness caused by this, and vaccination. Eighteen close-ended questions were administered, and responses were recorded as 'yes', 'no', or 'not sure'. HBV knowledge score was calculated based on the sum of correct answers. Each correct response scored one point and incorrect, missing or 'not sure' responses received no points. Categorical data are presented as number (%) and numerical data are expressed as median. Data were compared using Chi2 tests and level of significance was kept as P < 0.05. RESULTS: Parents (58.3% mothers) of 384 children (89.9% age < 5 years; 82% age-appropriately vaccinated) were included. Three hundred and twenty-two (83.9%) children were Hep-B3 vaccinated. 94.3%, 87.5%, and 29.2% parents knew about polio, tetanus, and hepatitis B vaccine. Overall, 41.2%, 15.8%, and 23% parents knew about hepatitis B transmission, consequences of infection, and prevention respectively. Only 7.6% parents knew about three-dose schedule of hepatitis B vaccination. Only 23% parents believed that vaccine could prevent HBV, 15.7% knew that HBV affects liver. Parents of Hep-B3 vaccinated children were significantly more aware about HBV than the parents of unvaccinated children (P < 0.05 for 17/18 questions). CONCLUSION: The knowledge and awareness among the parents about hepatitis B is poor. The Increasing knowledge/awareness about HBV among parents may improve Hep-B3 vaccination coverage.

RESUMO

INTRODUCTION: This study aimed to investigate the differences between pregnant women with chronic hepatitis B virus (HBV) infection and intrafamilial infection and those without intrafamilial infection. METHODS: HBV-DNA was extracted from the sera of 16 pregnant women with chronic hepatitis B (CHB) and their family members for gene sequencing and phylogenetic analyses. A total of 74 pregnant women with CHB were followed up from the second trimester to 3 months postpartum. Viral markers and other laboratory indicators were compared between pregnant women with CHB with and without intrafamilial infection. RESULTS: The phylogenetic tree showed that HBV lines in the mother-spread pedigree shared a node, whereas there was an unrelated genetic background for HBV lines in individuals without intrafamilial infection. From delivery to 3 months postpartum, compared with those without intrafamilial infection, pregnant women with intrafamilial infection were related negatively to HBV-DNA (ß = -0.43, 95% confidence interval [CI]: -0.76 to -0.12, p = 0.009), HBeAg (ß = -195.15, 95% CI: -366.35 to -23.96, p = 0.027), and hemoglobin changes (ß = -8.09, 95% CI: -15.54 to -0.64, p = 0.035) and positively to changes in the levels of alanine aminotransferase (ß = 73.9, 95% CI: 38.92-108.95, p < 0.001) and albumin (ß = 2.73, 95% CI: 0.23-5.23, p = 0.033). CONCLUSION: The mother-spread pedigree spread model differs from that of non-intrafamilial infections. Pregnant women with intrafamilial HBV infection have less hepatitis flares and liver damage, but their HBV-DNA and HBeAg levels rebound faster after delivery, than those without intrafamilial infection by the virus.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Introduction: Mother-to-child transmission of hepatitis B infection is one of the major routes of hepatitis B virus (HBV) infection in Africa. Amusingly, Africa is the only region yet to meet the World Health Organization's target of reducing the prevalence of HBV infection to less than 1% among children under 5 years of age by 2020. In Ghana, little has been documented about midwives' views on the factors impacting the successful implementation of mother-to-child transmission via HBV prevention programs. Objective: This study explored midwives' views on the challenges associated with the prevention of mother-to-child transmission of HBV infection in the La-Nkwantanang municipality. Methods: The study adopted an exploratory descriptive qualitative design and involved 14 midwives who were purposively recruited from a primary-level health facility in the La-Nkwantanang Municipality, Accra. Individual face-to-face interviews were conducted using an in-depth interview guide. The data were content analyzed using the six steps recommended by Braun and Clark. Results: Three main themes, namely, health professional or midwife factors and patient and health facility factors, negatively impacted the prevention of maternal-to-child transmission program. The five subthemes identified in this study included lack of awareness, financial constraints, and unavailability of logistics and protocols. The study recognized that midwives face many challenges even though they have a strong desire to prevent vertical transmission of HBV. Conclusion: The implementation of a mother-to-child transmission program is negatively impacted by many intrinsic, client, and health facility factors. Midwives who act as major stakeholders need to be periodically trained on the components and protocols for managing pregnant women living with HBV. The necessary logistics and management protocols need to be urgently provided. The skills and education obtained from the training will empower midwives to be knowledgeable about how to deliver quality care and provide education and support for HBV-infected pregnant women. The provision of logistics needed for the successful implementation of the program could avert delays associated with the administration of the hepatitis B birth dose vaccine and immunoglobulin to exposed newborns.

RESUMO

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.

RESUMO

Hepatitis B core-related antigen (HBcrAg) reflects the activity of intrahepatic covalently closed circular DNA. HBcrAg can be detected even in chronic hepatitis B patients in whom serum HBV DNA or hepatitis B surface antigen is undetectable. The HBcrAg measurement system was developed based on two concepts. One is a fully-automated and highly-sensitive HBcrAg assay (iTACT-HBcrAg) and the other is a point-of-care testing (POCT) that can be used in in resource-limited areas. iTACT-HBcrAg is an alternative to HBV DNA for monitoring HBV reactivation and predicting the development of hepatocellular carcinoma. This validated biomarker is available in routine clinical practice in Japan. Currently, international guidelines for the prevention of mother-to-child transmission recommend anti-HBV prophylaxis for pregnant women with high viral loads. However, over 95% of HBV-infected individuals live in countries where HBV DNA quantification is widely unavailable. Given this situation, a rapid and simple HBcrAg assay for POCT would be highly effective. Long-term anti-HBV therapy may have potential side effects and appropriate treatment should be provided to eligible patients. Therefore, a simple method of determining the indication for anti-HBV treatment would be ideal.

RESUMO

Viral hepatitis during pregnancy is common globally. In this review, we focus on the antenatal screen for hepatitis A, B, C and E, the prevention of mother-to-child transmission (MTCT) of hepatitis B and C, and the management of hepatitis A, B, C and E during pregnancy. Neonatal timely administration of hepatitis B immunoglobulin and hepatitis B vaccine is the cornerstone for preventing MTCT of hepatitis B virus (HBV), and perinatal antiviral prophylaxis with tenofovir disoproxil fumarate in mothers with positive HBeAg or HBV DNA >2 × 105 IU/ml also plays important roles in further reducing MTCT. Avoidance of risk practices in managing labor and delivery process of women with HCV infection may be useful to reduce MTCT of HCV. Early recognition of severe hepatic injury or liver failure associated with hepatitis viruses by regular liver function tests is critical to prevent maternal mortality associated with hepatitis.

RESUMO

Background: Syphilis, a prevalent sexually transmitted infection, poses severe risks, especially during pregnancy. This study aimed to elucidate the trends and impacts of syphilis in Guangxi, China, focusing on prevalence, clinical manifestations, and treatment outcomes in pregnant women and newborns. The objectives included understanding the demographic characteristics of affected pregnant women, analysing the clinical manifestations in newborns, and assessing the effectiveness of the treatment protocol. Methods: Conducted in adherence to ethical guidelines, a retrospective cohort study from January 2013 to December 2023 included 54,048 pregnant women tested for T. pallidum. Diagnosis involved a comprehensive approach, utilizing tests like the Toluidine Red Unheated Serum Test (TRUST) and the Treponema pallidum Particle Agglutination (TPPA) assay. Infant diagnosis and clinical manifestations were evaluated through a decade-long follow-up. Treatment protocols, including Benzathine penicillin, were implemented. Statistical analyses were conducted using SAS version 9.4. Results: Among 54,048 pregnant women, 0.10% were syphilis positive, correlating with a rise in hospitalizations. Newborns exhibited varied clinical manifestations, with neonatal pneumonia and jaundice being prevalent. The treatment protocol, especially with Benzathine penicillin, achieved a remarkable 100% cure success rate. The study noted a significant reduction in mother-to-child transmission. Syphilis in mothers and babies was diagnosed at different clinical stages, including primary, secondary, latent, and tertiary. Conclusion: This study underscores the escalating impact of syphilis on pregnant women and newborns in Guangxi, China. The findings highlight the necessity for robust preventive measures, early diagnosis, and effective treatment strategies. The observed 100% cure success rate with Benzathine penicillin emphasizes the importance of strict treatment protocols in mitigating the adverse effects of congenital syphilis and reducing its transmission.

RESUMO

BACKGROUND: Nigeria has the largest global burden of HIV new infections in children despite global and national concerted efforts at the reduction of mother-to-child transmission of HIV. The goal of this study was to determine the associations between maternal characteristics, practices and mother-to-child transmission of HIV infection among mothers living with HIV. METHODS: This is a hospital-based descriptive cross-sectional study. Information was obtained using interviewer-administered questionnaire from the 240 participants. Data were analyzed with SPSS version 26, and P < 0.05 was considered statistically significant. RESULTS: Out of the 240 mothers recruited, 129 (53.8%) were within 25-35 years of age, with a mean age of 31.08 ± 5.65. A total of 35 (14.6%) of the participants had at least a child with HIV infection. Maternal ART status before childbirth (AOR = 0.02, 95%CI = 0.01-0.05, P = < 0 .001) was the singular determinant of having a child with HIV infection. Mothers who delivered outside the health facility were about four-fold at risk of having an infected child (AOR = 3.89, 95%CI = 1.82-8.50, P = 0.070). CONCLUSION: The prevalence rate of mother-to-child transmission of HIV is high. Routine HIV testing services and the provision of accessible and affordable reproductive health services are recommended for all women of childbearing age.

RESUMO

In May 2024, the Swedish Reference Group on Antiviral Therapy updated the guidelines on management of HIV infection in pregnancy. The most important recommendations and revisions were: (i) ART during pregnancy should be started as early as possible and continue after delivery; (ii) Suppressive ART should normally not be modified; (iii) The treatment target of HIV RNA <20 copies/ml remains; (iv) Dolutegravir/emtricitabine/tenofovir DF is the first-line drug combination also in pregnant women and women planning pregnancy; (v) There is no evidence of an increased risk of neural tube defects associated with dolutegravir; (vi) Mode of delivery for women with effective ART and HIV RNA <200 copies/ml should follow standard obstetric procedures; (vii) Caesarean section is recommended if HIV RNA ≥200 copies/ml; (viii) Scalp electrode, foetal blood sampling and/or vacuum delivery should be used on strict indications, but does not necessitate intensified infant prophylaxis; (ix) Management and mode of delivery in case of premature or full-term rupture of membranes should follow standard obstetric procedures; (x) Recommended infant antiretroviral prophylaxis has been updated; (xi) The duration of infant antiretroviral prophylaxis (gestational age ≥35 weeks and mother on effective ART and HIV RNA <200 copies/ml) has been changed from 4 to 2 weeks; (xii) Infants born to women with HIV RNA ≥200 copies/ml should receive 4 weeks of combination prophylaxis; (xiii) Fertility evaluation and assisted reproduction should be offered to women on suppressive ART according to the same principles as for other women; (xiv) Women living with HIV should still be advised against breastfeeding; (xv) Women who nevertheless opt to breastfeed should be offered intensified support and follow-up.

RESUMO

Background: Currently, Dolutegravir (DTG)-based regimens are administered to women on Option B plus to prevent mother-to-child transmission (MTCT) of the virus. However, its effect on reducing MTCT of human immunodeficiency virus (HIV) among HIV-exposed infants over the previously used Efavirenz (EFV)-based regimen is unknown. Objective: This study aimed to compare the effects of DTG-based and EFV-based regimens on the MTCT of HIV among HIV-exposed infants in Ethiopia. Methods: An uncontrolled before-and-after study design was conducted among 958 mother-infant pairs (479 on EFV-based and 479 on DTG-based regimens) enrolled in the prevention of mother-to-child transmission (PMTCT) care from September 2015 to February 2023. The outcome variable was the HIV infection status among the exposed infants. A log-binomial model was employed, and the proportion was computed to compare the incidence of MTCT of HIV in both groups. The risk ratio (RR) with a 95% confidence interval (CI) was calculated to assess the predictor variables. Results: Mothers on DTG-based regimens were approximately 44% (adjusted risk ratio (aRR): 0.56; 95% CI: 0.44, 0.70) less likely to transmit HIV to their infants than those on EFV-based regimens. In addition, poor or fair adherence to antiretroviral therapy (ART) (aRR: 5.82; 95% CI: 3.41, 9.93), home delivery (aRR: 3.61; 95% CI: 2.32, 5.62), mixed feeding practice (aRR: 1.83; 95% CI: 1.45, 2.3) and not receiving antiretroviral prophylaxis (aRR: 3.26; 95% CI: 1.6, 6.64) were found to increase the risk of MTCT of HIV infection, whereas older maternal age (aRR: 0.93; 95% CI: 0.9, 0.96) was a protective factor. Conclusion: Mother-to-child transmission of HIV was less frequently observed in mother-infant pairs exposed to the DTG-based regimens as compared to those exposed to the EFV-based regimens. Thus, DTG-based first-line ART regimens supplementation should be sustained to achieve global and national targets for zero new infections in HIV-exposed infants.

RESUMO

Mother-to-child transmission (MTCT) of HIV-1 and associated mortality continue to occur at unacceptably high rates, despite the extensive rollout and implementation of Prevention of Mother-to-Child Transmission (PMTCT) Programs, including the modified versions of Option B and B+ in 2010 and 2012, respectively. Maternal HIV viral load (VL) and socio-behavioral factors sustaining MTCT in Rwanda remain largely unexplored. The study examined the effects of socio-behavioral factors on maternal VL and their contribution to in utero transmission of HIV-1 in the context of Rwanda's HIV epidemic. A prospective cohort study was conducted in 862 mother-baby pairs enrolled in 10 PMTCT clinics in Rwanda. VL was determined on plasma and Dried Blood Spots samples, whereas HIV DNA PCR was performed to determine in utero MTCT of HIV of the babies immediately at birth and then at 3 weeks, 4 weeks, 6 months, and 18 months, together with HIV antibody testing to determine other forms of MTCT of HIV. Quantitative data on socio-behavioral factors were collected through a structured questionnaire. Linear regression and univariate analysis of variances using SPSS 25.0 were used to test the hypotheses. We found 22/862 (2.55%) cases of in utero transmission and a total of 32/862 (3.7%) cases of MTCT of HIV-1 over 18 study months. Maternal VL at delivery was significantly associated with the risk of in utero transmission of HIV-1. Socio-behavioral factors associated with elevated maternal VL at delivery included alcohol, smoking, multiple sexual partners, mothers' income, being a casual laborer, and distance to health care services. We report an MTCT rate of 3.7% in our study population over the 18 months, higher than the national average of 1.5%, the majority of which occurred in utero. MTCT cases were attributable to failure to suppress maternal VL.

RESUMO

In 2022, 54% of 1.5 million children (age 0-14) living with HIV had access to anti-retroviral medication (ART). Adherence to ART for pregnant or breastfeeding HIV + women is critical for maintaining their personal health and to prevent mother-to-child-transmission (MTCT). For HIV + infants, adherence is essential to establish early viremic control and is contingent on caregiver administration. We conducted a scoping review to systematically identify and categorize the influences on ART adherence for pregnant or breastfeeding HIV + women and their HIV + infants. We searched databases in June 2023 and employed the Social-Ecological Model (SEM) to organize facilitators and barriers to adherence referenced in published articles. All articles published before 2016 were excluded due to updated guidelines from WHO on MTCT and ART. Our analysis included 52 articles. 50/52 took place in Africa and used cross-sectional and mixed-methods design. Barriers to adherence for pregnant or breastfeeding HIV + women included maternal education, self-efficacy, social support, and social/economic context. Barriers to infant adherence included development, nutrition, age of treatment initiation, disclosure, and ART side effects. Additional facilitators and barriers to adherence are presented at family, extra-familial, and socio-cultural SEM levels. Stigma was the most salient barrier referenced across the entire continuum of HIV care and all SEM levels. This review revealed a dearth of literature focusing on HIV + infants who are dependent on their caregivers for ART adherence and lack of a standard adherence measure. We identified multi-leveled influences on adherence impacting both the mother and infant and are amenable to public health intervention.
