Background: Mother-to-child transmission (MTCT) of HIV, has been a major global public health burden. Despite the use of antiretroviral prophylaxis by HIV-positive pregnant women and their infants, safe obstetric practice and safe infant feeding habits in the prevention of MTCT of HIV, the prevalence of HIV among HIV-exposed infants is still high in Cameroon.Objective: Our objectives were to determine the prevalence, assess the predictors and determine the effect of combination antiretroviral therapy (cART) on MTCT of HIV at the regional hospital in Bamenda, Cameroon.Methods: This was a retrospective study. Secondary data from 877 HIV-exposed infants aged ≤ 72 weeks were extracted from the records between January 2008 and December 2014. The predictors and effect of cART on MTCT of HIV were analysed using a multivariable logistic regression model and risk analysis, respectively.Results: Out of 877 HIV-exposed infants, 62 were positive for HIV, giving a prevalence of 7.1%. Maternal antiretroviral intervention and infant age group were statistically significant predictors of MTCT of HIV. HIV-positive mothers who were on cART were 2.49 times less likely to transmit HIV than those who were not on cART.Conclusion: In order to reduce the prevalence of HIV among HIV-exposed infants, maternal antiretroviral intervention should be targeted and the use of cART by HIV-positive pregnant women should be encouraged.

Background: This observational study describes implementation of HIV retesting of HIV-negative women in prevention of mother-to-child transmission (PMTCT) services in Zambia. Methods: Uptake of retesting and PMTCT services were compared across age, parity, and weeks of gestation at the time of the first HIV test, antiretrovirals regime, and HIV early diagnosis results from infants born to HIV-positive mothers. Results: A total of 19 090 pregnant women were tested for HIV at their first antenatal visit, 16 838 tested HIV-negative and were offered retesting 3 months later: 11 339 (67.3%) were retested; of those, 55 (0.5%) were HIV positive. Uptake of the PMTCT package by women HIV positive at retest was not different but HIV-exposed infants born to women who retested HIV positive were infected at a higher rate (11.1%) compared to those born to women who tested HIV positive at their initial test (3.2%). Conclusion: We suggest rigorously (1) measuring the proportion of MTCT attributable to women who seroconvert during pregnancy and possibly adjust PMTCT approaches and (2) addressing the substantial loss to follow-up of HIV-negative pregnant women before HIV retesting.

Since the scale-up for prevention of mother-to-child transmission (PMTCT) services, rates of HIV infection among exposed infants have significantly declined. However, current achievements fell short of achieving the target sets. We investigated mother-to-child transmission (MTCT) of HIV infection and its determinants among HIV-exposed infants on care at Dilchora Referral Hospital in Dire Dawa City Administration. A retrospective institutional cohort study was conducted by reviewing follow-up records of HIV-exposed infants who were enrolled into care. Infants’ HIV serostatus was the outcome measure of the study. Bivariate and multivariate logistic regressions were employed to identify significant determinants. Of the 382 HIV-exposed infants enrolled into care, 60 (15.7%) became HIV positive. Rural residence (AOR: 3.29; 95% CI: 1.40, 7.22), home delivery (AOR: 3.35; 95% CI: 1.58, 8.38), infant not receiving ARV prophylaxis at birth (AOR: 5.83; 95% CI: 2.84, 11.94), mixed feeding practices (AOR: 42.21; 95% CI: 8.31, 214.38), and mother-child pairs neither receiving ARV (AOR: 4.42; 95% CI: 2.01, 9.82) were significant independent determinants of MTCT of HIV infection. Our findings suggest additional efforts to intensify scale-up of PMTCT services in rural setting and improve institutional delivery and postnatal care for HIV positive mothers and proper follow-up for HIV-exposed infants.

Objective: To characterize human immunodeficiency virus (HIV)-positive infants among HIV-exposed infants (HEIs) in Nairobi County for public health action. Methods: We conducted a retrospective review of records of HEIs’ HIV polymerase chain reaction (PCR) results in Nairobi County in 2015, excluding confirmatory PCR-positive results. HIV-exposed infant registry data were entered into Microsoft Excel and descriptive and associative statistics were calculated with OpenEpi software. Results: A total of 5802 HEI records were analyzed, with a median age of 4.5 (interquartile range, 8.5) months; 342 (5.9%) tested positive, 51% were female, and 4420 (76.2%) were seen at maternal and child health clinics. Standard highly active antiretroviral therapy intervention was given to 184 (60.3%) of the mothers of exposed infants, and 178 (53%) of the HIV-positive infants received active antiretroviral therapy. A total of 3464 (59.7%) HEIs had PCR done within the first 2 months, and 119 (3.4%) tested positive. The average turnaround time for PCR samples was 28 ± 22 days, and a total of 191 (3.3%) HIV-positive HEIs were exclusively breastfed for the first 6 months of life. Conclusion: The recorded mother-to-child transmission (MTCT) rate of 5.9% in Nairobi County is lower than the 2015 national rate, which suggests the Nairobi prevention of mother-to-child transmission efforts are moderately effective. However, results from this study show that Kenya will struggle to meet the MTCT 2020 target rate of <5%.

Background: The Mahalapye district health management team (DHMT) conducts regular audits to evaluate the standard of services delivered to patients, one of which is the prevention of mother-to-child-transmission (PMTCT) programme. Xhosa clinic is one of the facilities in Mahalapye which provides a PMTCT programme.Aim: This audit aimed to identify gaps between the current PMTCT clinical practice in Xhosa clinic and the Botswana PMTCT national guidelines.Setting: This audit took place in Xhosa clinic in the urban village of Mahalapye, in the Central District of Botswana.Methods: This was a retrospective audit using PMTCT Xhosa clinic records of pregnant mothers and HIV-exposed babies seen from January 2013 to June 2013.Results: One hundred and thirty-three pregnant women registered for antenatal care. Twenty-five (19%) knew their HIV-positive status as they had been tested before their pregnancy or had tested HIV positive at their first antenatal clinic visit. More than two-thirds of the 115 pregnant women (69%) were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67%) took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89%) were HIV DNA PCR negative at 6 weeks. Thirty-two (73%) children were given cotrimoxazole prophylaxis between 6 and 8 weeks.Conclusion: The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.

Many HIV-positive pregnant women and infants are still not receiving optimal services, preventing the goal of eliminating mother-to-child transmission (MTCT) and improving maternal child health overall. A Rapid Results Initiative (RRI) approach was utilized to address key challenges in delivery of prevention of MTCT (PMTCT) services including highly active antiretroviral therapy (HAART) uptake for women and infants. The RRI was conducted between April and June 2011 at 119 health facilities in five districts in Nyanza Province, Kenya. Aggregated site-level data were compared at baseline before the RRI (Oct 2010–Jan 2011), during the RRI, and post-RRI (Jul–Sep 2011) using pre-post cohort analysis. HAART uptake amongst all HIV-positive pregnant women increased by 40% (RR 1.4, 95% CI 1.2–1.7) and continued to improve post-RRI (RR 1.6, 95% CI 1.4–1.8). HAART uptake in HIV-positive infants remained stable (RR 1.1, 95% CI 0.9–1.4) during the RRI and improved by 30% (RR 1.3, 95% CI 1.0–1.6) post-RRI. Significant improvement in PMTCT services can be achieved through introduction of an RRI, which appears to lead to sustained benefits for pregnant HIV-infected women and their infants.

Despite the availability of efficacious prevention of mother-to-child transmission (PMTCT) interventions and improved access to preventive services in many developing countries, vertical HIV transmission persists. A matched case–control study of HIV-exposed infants between January and June 2012 was conducted at 20 clinics in Kenya. Cases were HIV-infected infants and controls were exposed, uninfected infants. Conditional logistic regression analysis was conducted to determine characteristics associated with HIV infection. Forty-five cases and 45 controls were compared. Characteristics associated with HIV-infection included poor PMTCT service uptake such as late infant enrollment (odds ratio [OR]: 7.1, 95% confidence interval [CI]: 2.6–16.7) and poor adherence to infant prophylaxis (OR: 8.3, 95%CI: 3.2–21.4). Maternal characteristics associated with MTCT included lack of awareness of HIV status (OR: 5.6, 95%CI: 2.2–14.5), failure to access antiretroviral prophylaxis (OR: 22.2, 95%CI: 5.8–84.6), and poor adherence (OR: 8.1, 95%CI: 3.7–17.8). Lack of clinic-based HIV education (OR: 7.7, 95%CI: 2.0–25.0) and counseling (OR: 8.3, 95%CI: 2.2–33.3) were reported by mothers of cases. Poor uptake of PMTCT services and a reported absence of HIV education and counseling at the clinic were associated with MTCT. More emphasis on high-quality, comprehensive PMTCT service provision are urgently needed to minimize HIV transmission to children.

Abstract Background : Failure to retain HIV-positive pregnant women on antiretroviral therapy (ART) leads to increased mortality for the mother and her child. This study evaluated different retention measures for women’s engagement along the continuum of care for prevention of mother-to-child transmission (PMTCT) option B+ services in Mozambique. Methods : We compared ‘point’ retention (patient’s presence in care 12-month post-ART initiation or any time thereafter) with the following definitions: alive and in care 12 month post-ART initiation (Ministry of Health; MOH); attendance at a health facility up to 15-month post-ART initiation (World Health Organization; WHO); alive and in treatment at 1-, 2-, 3-, 6-, 9-, and 12-month post-ART initiation (Inter-Agency Task Team; IATT); and alive and in care 12-month post-ART initiation with ≥75% appointment adherence during follow-up (i.e. ‘appointment adherence’ retention) or with ≥75% of appointments met on time during follow-up (i.e. ‘on-time adherence’ retention). Kaplan-Meier survival curves were produced to assess variability in retention rates. We used ‘on-time adherence’ retention as our reference to estimate sensitivity, specificity, and proportion of misclassified patients. Results : Considering the ‘point’ retention definition, 16,840 HIV-positive pregnant women enrolled in option B+ PMTCT services were identified as ‘retained in care’ 12-month post-ART initiation. Of these, 60.3% (95% CI 59.6–61.1), 84.8% (95% CI 84.2–85.3), and 16.4% (95% CI 15.8–17.0) were classified as ‘retained in care’ using MOH, WHO, and IATT definitions, respectively, and 1.2% (95% CI 1.0–1.4) were classified as ‘retained in care’ using the ‘≥75% on-time adherence’ definition. All definitions provided specificity rates of ≥98%. The sensitivity rates were 3.0% with 78% of patients misclassified according to the WHO definition and 4.3% with 54% of patients misclassified according to the MOH definition. The ‘point’ retention definition misclassified 97.6% of patients. Using IATT and ‘appointment adherence’ retention definitions, sensitivity rates (9.0% and 11.7%, respectively) were also low; however, the proportion of misclassified patients was smaller (15.9% and 18.3%, respectively). Conclusion : More stringent definitions indicated lower retention rates for PMTCT programs. Policy makers and program managers should include attendance at follow-up visits when measuring retention in care to better guide planning, scale-up, and monitoring of interventions.
