Background: Uganda has successfully reduced pediatric HIV infections through prevention of mother-to-child transmission of HIV (PMTCT) programs, yet little is known about adherence to infant-specific components of interventions. We hypothesized that infants born to mothers receiving the WiseMama (WM) electronic drug monitoring (EDM)-based adherence intervention would have increased uptake of six-week post-natal nevirapine (NVP) infant prophylaxis and better adherence to six-week early infant diagnosis (EID) HIV testing. Methods: At two sites in Uganda, the Wise Infant Study (WIN) prospectively followed an infant cohort. Infants were born to women enrolled in an RCT testing the effect of real-time reminders delivered via EDM on maternal adherence to antiretroviral therapy. We assessed intrapartum and discharge receipt of NVP prophylaxis using pharmacy and infant HIV DNA testing laboratory data. Results: Of 121 women eligible for WIN, 97 (80%) consented and enrolled; 46 had been randomized to control and 51 to intervention. There were no differences in receipt of a six-week NVP supply (control 87%, intervention 82%, p = 0.53). Receipt of any NVP prophylaxis did not vary by delivery location (p = 0.35), and although 12% of infants were delivered at non-study health facilities, they were not less likely to receive NVP at discharge (p = 0.37). Among infants with a completed HIV test, there was no difference in mean time to first test (control 52 days (SD 18), intervention 51 days (SD 15), p = 0.86). Only one infant, in the control group, tested positive for HIV. Conclusion and Global Health Implications: We found no significant differences in adherence to infant PMTCT practices between intervention and control infants with relatively high rates of NVP receipt albeit with suboptimal adherence to six-week EID testing. Further work is needed to ensure improved access, uptake, and follow-up of HIV-exposed infants in the Option B+ era.

Background: The success of any prevention of mother-to-child transmission (PMTCT) program is assessed by the proportion of HIV-exposed infants that sero-convert at the end of all risk exposures. Although adopting the best feeding option for HIV-exposed infants is one of the factors that impact PMTCT outcomes, there is limited data on the assessment of PMTCT success rates based on antiretroviral interventions and feeding options. This study assesses the success rate of PMTCT service based on antiretroviral interventions and feeding options. Methods: Eighty-five HIV-infected mothers previously in care were enrolled in a prospective cohort study. Folders and structured questionnaires were used to extract data on mother-infant pair and the first CD4, count of infected mothers on enrolment at PMTCT clinic. Dry blood spot samples were obtained from exposed infants for early infant diagnosis. Results were analyzed using the SPSS software. Results: The mean age of enrolled mothers was 31.3 ± 4.4 years, and an average CD4+ T-lymphocyte count of 368.6 ± 216.2 cells/µl. Seven (8.2%) of the HIV-exposed infants were positive for HIV-1 based on early infant diagnosis results. Overall PMTCT success rate (PMTCTSR) was 91.8%. HIV-1 prevalence of 5.0%, 0% and 21.1% was found among infants of patients who opted for breastfeeding, replacement feeding, and mixed feeding respectively thus yielding PMTCT success rates of 95%, 100% and 78.9%. Pediatric antiretroviral interventions success rates in HIV-exposed infants was 95.8%, 80.0% and 66.7% based on age groups ≤ 6 months, > 6 ≤ 12 months, and > 12 ≤ 18 months respectively. Conclusion and Global Health Implications: Quality PMTCT service is vital for successful prevention of mother-to-child transmission of HIV. Implementation of more dynamic approaches such as adherence to option B+ guidelines in PMTCT service in our settings can further reduce mother-to-child transmission of HIV and improve outcomes.

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%.

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.

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.

Background: In line with global standards and progress made in Prevention of Mother-to-Child Transmission (PMTCT), an assessment of the outcome of Early Infant Diagnosis in northern Nigeria is necessary to evaluate progress towards a zero Human immunodeficiency Virus (HIV) infection rate among children. Objectives: This study assessed the infection rate and risk factors for mother-to-child HIV transmission among HIV-exposed children in Kano, northwest Nigeria. Method: Using a retrospective cohort design, pregnant HIV-positive women and their exposed infants were recruited over a period of six years (2010 to 2016). Participants were enrolled during pregnancy or at delivery from the PMTCT clinic of a tertiary health facility in Kano, Nigeria. The main observations of the study were Early infant diagnosis positivity for HIV at 6 weeks and the risk factors for positivity. Results: Of the 1,514 infants studied, Early Infant Diagnosis was positive for HIV among 13 infants (0.86%). Infants whose mothers did not have antiretroviral therapy (adjusted Prevalence Ratio aPR = 2.58, 95%CI [1.85- 3.57]); who had mixed feeding (aPR = 12.06, 95%CI [9.86- 14.70]) and those not on antiretroviral prophylaxis (aPR = 20.39, 95%CI [16.04- 25.71]) were more likely to be infected with HIV. HIV-exposed infants on nevirapine and zidovudine prophylaxis accounted for 95% and 74%, respectively, and were less likely to be infected with HIV. Conclusion: HIV infection rate remains high among HIV-exposed infants whose mothers did not receive PMTCT services. Scaling up proven interventions of early commencement of antiretroviral treatment for mothers, adherence to antiretroviral prophylaxis and avoidance of mixed feeding among HIV-exposed infants would protect future generations from HIV infection.

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.
