AIDS Res Ther 2024; 21:39. [PMID: 38849895 PMCID: PMC11157738 DOI: 10.1186/s12981-024-00623-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 05/20/2024] [Indexed: 06/09/2024] Open
Abstract
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.

Abstract
BACKGROUND Mother-To-Child-Transmission (MTCT) of Human Immunodeficiency Virus (HIV) occurs during pregnancy, delivery and breastfeeding, and cause infection among several new-borns. However, there is limited recent evidence on the burden of MTCT of HIV in Ethiopia from a large-scale data. Thus, this study aimed to determine the positivity rate, trend and associated risk factors of MTCT among HIV-exposed infants. METHODOLOGY A cross-sectional study was conducted among 5,679 infants whose specimen referred to Ethiopian Public Health Institute HIV referral laboratory for Early Infant Diagnosis (EID) from January 01, 2016, to December 31, 2020. Data were extracted from the national EID database. Frequencies and percentages were used to summarize the data on characteristics of infants. Logistic regression analysis was employed to identify factors associated with positivity rate of MTCT of HIV. Level of significance was set at 5%. RESULTS The mean age of the infants was 12.6 (± 14.6) weeks with an age range of 4 to 72 weeks. Half of the infants (51.4%) were female. The positivity rate of MTCT decreased from 2.9% in 2016 to 0.9% in 2020 with five-year average positivity rate of 2.6%. HIV test after six weeks (Adjusted odds ratio (AOR) = 2.7; 95% confidence interval (CI): (1.8-4.0,)); p < 0.001), absence of prevention of mother-to-child-transmission (PMTCT) service (AOR = 4.6; 95% CI: (2.9-7.4)); p = 0.001), nevirapine prophylaxis not received (AOR = 2.0; 95% CI: (1.3-3.2)); p < 0.001), and unknown ART status of the mother at delivery (AOR = 11; 95% CI: (5.5-22.1)); p < 0.001) were significantly associated with MTCT of HIV. CONCLUSION The positivity rate of MTCT of HIV was showing declining tendency gradually in the study period. Strengthening PMTCT service, early HIV screening and starting ART for pregnant women, and early infant diagnosis are required to reduce the burden of HIV infection among infants exposed to HIV.

Adherence to option B+ and its association with disclosure status and counseling among HIV-positive pregnant and lactating women in Ethiopia: systematic review and meta-analysis. Public Health 2022; 211:105-113. [PMID: 36058198 DOI: 10.1016/j.puhe.2022.07.016] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 05/22/2022] [Accepted: 07/20/2022] [Indexed: 10/14/2022]
Abstract
OBJECTIVES This systematic review and meta-analysis aimed to assess the pooled estimate of option B+ level of adherence and its association with disclosure status and counseling among pregnant and lactation women in Ethiopia after option B+ implementation. STUDY DESIGN Systematic review and meta-analysis. METHODS We searched Web of Science, MEDLINE, PUBMED, Scopus, Embase, CINAHL, and Google Scholar databases for studies reporting adherence to option B+ and its association with disclosure status and counseling among pregnant and lactating women in Ethiopia. Heterogeneity was assessed by forest plot, Cochran's Q test, and I2 test. A random effects model was calculated to estimate the pooled prevalence of adherence toward option B+. RESULTS We included eight studies, which gives a total of 1852 pregnant and lactating women in this systematic review and meta-analysis. The overall pooled estimate of good adherence toward option B+ antiretroviral therapy (ART) drug among pregnant and lactating women in Ethiopia was 84.23% (95% confidence interval [CI]: 80.79-87.66). Women who have disclosed their HIV status to their partner (adjusted odds ratio = 4.48, 95% CI: 1.86-10.76) and got counseling during the antenatal period (adjusted odds ratio = 5.02, 95% CI: 2.43-10.34) had a positive association with good adherence to option B+ ART drugs. CONCLUSION Four of five pregnant and lactating women have good adherence to option B+ ART drugs in Ethiopia. Therefore, promoting HIV disclosure status to partners and enhancing counseling services should be strengthened to improve adherence toward option B+ among pregnant and lactating women.

Abstract
Objective In 2015, the WHO released new guidelines to reduce mother‐to‐child transmission (MTCT) of HIV. The recommendations, known as Option B+, included initiation of lifelong highly active antiretroviral therapy regardless of CD4 count for all HIV‐positive pregnant and breastfeeding mothers. For infants, exclusive breastfeeding for 6 months and antiviral therapy were sanctioned. Targets of <5% transmission in breastfeeding populations and <2% in non‐breastfeeding populations were set. This review evaluated the impact of Option B+ on MTCT in African countries. Methods Using the PRISMA guidelines, a systematic search of PubMed and Google Scholar databases was conducted to identify relevant studies published between 2015 and 2021. All studies meeting inclusion criteria were evaluated. Results Of the 687 references screened, 22 studies from 11 countries (Cameroon, Ethiopia, Lesotho, Malawi, Rwanda, South Africa, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe) met inclusion criteria. Six studies reported MTCT rates of <2%, 16 studies reported rates of 2–5% and two studies (Uganda and Zambia) reported 6% or more. Rates varied within the same study at different time points postpartum and amongst studies from the same country. Overall, reported MTCT rates appear to be close to WHO targets. However, diverse study designs, selection bias, extensive loss to follow‐up and undocumented adherence rates to Option B+ protocols may significantly underestimate MTCT rates of HIV in Africa. Conclusions Standardised protocols for impact evaluation must be established to provide evidenced‐based data on the efficacy of Option B+ in Africa.

Final HIV status outcome for HIV-exposed infants at 18 months of age in nine states and the Federal Capital Territory, Nigeria. PLoS One 2022; 17:e0263921. [PMID: 35157737 PMCID: PMC8843197 DOI: 10.1371/journal.pone.0263921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Accepted: 01/29/2022] [Indexed: 11/23/2022] Open
Abstract
Introduction While antiretroviral therapy (ART) coverage for pregnant women has undergone steady scale-up, Nigeria’s final mother- to-child transmission of HIV (MTCT) rate remains unacceptably high at 10%. This study aimed to determine final outcomes (MTCT rates) and their correlates among HIV-exposed infants (HEI) in nine states and the Federal Capital Territory, Nigeria. Methods This retrospective, cross-sectional study was conducted at 96 primary, secondary and tertiary health facilities supported by the Institute of Human Virology Nigeria. Data was abstracted for a birth cohort of HEI born between October 30, 2014 and April 30, 2015 whose 18–24 month final outcome was assessed by October 30, 2016. Only infants with a six-week first DNA PCR result, and a rapid HIV antibody test result at age 18 to 24 months were included. Multivariate logistic regression (adjusted odds ratios [aORs]) evaluated for predictors of HIV positivity at ≥18 months. Results After testing at ≥18 months, 68 (2.8%) of the 2,405 exposed infants in the birth cohort were HIV-positive. After a minimum of 18 months of follow-up, 51 (75%) HIV-positive infants were alive on ART; 7 (10%) had died, 5 (7.3%) were lost to follow-up and 5 (7.3%) were transferred out. Rural maternal residence, lack of maternal ART/ARV prophylaxis, mixed infant feeding and infant birth weight less than 2.5 kg correlated with an HIV-positive status for infant final outcomes. Conclusion The final HIV positivity rate of 2.8% is encouraging, but is not population-based. Nevertheless, supported by our findings, we recommend continued programmatic focus on early access to quality prenatal care and maternal ART for pregnant women, especially for women living with HIV in rural areas. Furthermore, implementation of nationwide sensitization and education on six-months’ exclusive infant breastfeeding with concurrent maternal ART should be strengthened and sustained to reduce MTCT rates.

The perceived determinants and recommendations by mothers and healthcare professionals on the loss-to-follow-up in Option B+ program and child mortality in the Amhara region, Ethiopia. BMC Infect Dis 2020; 20:876. [PMID: 33228559 PMCID: PMC7686694 DOI: 10.1186/s12879-020-05583-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 11/03/2020] [Indexed: 11/13/2022] Open
Abstract
Background The third United Nations Sustainable Development Goal includes a commitment to end AIDS-related death by 2030. In line with the Goal, Option B+ programs hold a great promise for eliminating vertical transmission of HIV. Option B+ was introduced in 2013 in Ethiopia. The Global Plan identified Ethiopia as one of 22 high priority countries requiring improvement in prevention of mother to child HIV transmission services. Despite HIV treatment being free in Ethiopia, only 59% of children are on treatment. The discrepancies in high uptake of Option B+ and low numbers of children in Ethiopia can be attributed to Loss-to-follow-up, which is estimated from 16 to 80%. While LFTU is expected in the region, no-to-minimal evidence exists on the magnitude and its determinants, which hampers the development of interventions and strategies to reduce LFTU. The purpose of this study is to explore perception of mothers and healthcare providers on determinants of and recommendations to reduce LTFU and HIV exposed infants’ mortality. Method Explorative, descriptive qualitative study conducted in five zones of Amhara region. The sample consisted of mothers enrolled to the option B+ programs at the five referral hospitals PMTCT departments, nurses and midwives working in those departments, and HIV officers in zonal departments. Data were collected in 2019 using in-depth interviews. Data were analyzed using content analysis and deduced to themes. Results Overall, nine themes were identified from the interviews. Five themes represented the determinants of LTFU and mortality while four themes addressed the recommendations to reduce LFTU among mothers and their infant mortality. The determinants themes centered on apathy, stigma and discrimination, poor access to services, healthcare providers behavior and attitudes, and social determinants of health. While recommendations themes suggested that improving access, capitalizing on psychosocial support, education and awareness, and empowerment. Conclusions Social and structural issues are major contributors to low retention of mothers and death of children due to HIV. A multi-stakeholder approach, including structural changes, are required to support women and their children to ensure that individuals, communities and country enjoy the full benefits of option B+ and lead to an HIV free generation.
