BackgroundEarly diagnosis of HIV in infants provides a critical opportunity to strengthen follow-up of HIV-exposed children and assure early access to antiretroviral (ARV) treatment for infected children. This study describes findings from an Early Infant Diagnosis (EID) program and the effectiveness of a prevention of mother-to-child transmission (PMTCT) intervention in six health facilities in Cross-River and Akwa-Ibom states, south-south Nigeria.MethodsThis was a retrospective study. Records of 702 perinatally exposed babies aged six weeks to 18 months who had a DNA PCR test between November 2007 and July 2009 were reviewed. Details of the ARV regimen received to prevent mother-to-child transmission (MTCT), breastfeeding choices, HIV test results, turn around time (TAT) for results and post test ART enrolment status of the babies were analysed.ResultsTwo-thirds of mother-baby pairs received ARVs and 560 (80%) babies had ever been breastfed. Transmission rates for mother-baby pairs who received ARVs for PMTCT was 4.8% (CI 1.3, 8.3) at zero to six weeks of age compared to 19.5% (CI 3.0, 35.5) when neither baby nor mother received an intervention. Regardless of intervention, the transmission rates for babies aged six weeks to six months who had mixed feeding was 25.6% (CI 29.5, 47.1) whereas the transmission rates for those who were exclusively breastfed was 11.8% (CI 5.4, 18.1). Vertical transmission of HIV was eight times (AOR 7.8, CI: 4.52-13.19) more likely in the sub-group of mother-baby pairs who did not receive ARVS compared with mother-baby pairs that did receive ARVs. The median TAT for test results was 47 days (IQR: 35-58). A follow-up of 125 HIV positive babies found that 31 (25%) were enrolled into a paediatric ART program, nine (7%) were known to have died before the return of their DNA PCR results, and 85 (67%) could not be traced and were presumed to be lost-to-follow-up.ConclusionReduction of MTCT of HIV is possible with effective PMTCT interventions, including improved access to ARVs for PMTCT and appropriate infant feeding practices. Loss to follow up of HIV exposed infants is a challenge and requires strategies to enhance retention.

In December 2016, the Nigerian Federal Ministry of Health updated its HIV guidelines to a Treat All approach, expanding antiretroviral therapy (ART) eligibility to all individuals with HIV infection, regardless of CD4+ cell count, and recommending ART be initiated within two weeks of HIV diagnosis (i.e., the Test and Treat strategy). The Test and Treat policy was first piloted in 32 local government areas (LGAs). The primary objective of this study was to evaluate the clinical outcomes of adult patients initiated on ART within two weeks of HIV diagnosis during this pilot. We conducted a retrospective cohort analysis of patients who initiated ART within two weeks of new HIV diagnosis between October 2015 and September 2016 in eight randomly selected LGAs participating in the Test and Treat pilot study. 2,652 adults were newly diagnosed and initiated on ART within two weeks of HIV diagnosis. Of these patients, 8% had documentation of a 12-month viral load measurement, and 13% had documentation of a six-month viral load measurement. Among Test and Treat patients with a documented viral load, 79% were suppressed (≤400 copies/ml) at six months and 78% were suppressed at 12 months. By 12 months post-ART initiation, 34% of the patients who initiated ART under the Test and Treat strategy were lost to follow-up. The median CD4 cell count among patients initiating ART within two weeks of HIV diagnosis was 323 cells/mm 3 (interquartile range, 161–518). While randomized controlled trials have demonstrated that Test and Treat strategies can improve patient retention and increase viral suppression compared to standard of care, these findings indicate that the effectiveness of Test and Treat in some settings may be far lower than the efficacy demonstrated in randomized controlled trials. Significant attention to the way Test and Treat strategies are implemented, monitored, and improved particularly related to early retention, can help expand access to ART for all patients.

BackgroundThe Nigerian Antiretroviral therapy (ART) program started in 2004 and now ranks among the largest in Africa. However, nationally representative data on outcomes have not been reported.MethodsWe evaluated retrospective cohort data from a nationally representative sample of adults aged ≥15 years who initiated ART during 2004 to 2012. Data were abstracted from 3,496 patient records at 35 sites selected using probability-proportional-to-size (PPS) sampling. Analyses were weighted and controlled for the complex survey design. The main outcome measures were mortality, loss to follow-up (LTFU), and retention (the proportion alive and on ART). Potential predictors of attrition were assessed using competing risk regression models.ResultsAt ART initiation, 66.4 percent (%) were females, median age was 33 years, median weight 56 kg, median CD4 count 161 cells/mm3, and 47.1% had stage III/IV disease. The percentage of patients retained at 12, 24, 36 and 48 months was 81.2%, 74.4%, 67.2%, and 61.7%, respectively. Over 10,088 person-years of ART, mortality, LTFU, and overall attrition (mortality, LTFU, and treatment stop) rates were 1.1 (95% confidence interval (CI): 0.7–1.8), 12.3 (95%CI: 8.9–17.0), and 13.9 (95% CI: 10.4–18.5) per 100 person-years (py) respectively. Highest attrition rates of 55.4/100py were witnessed in the first 3 months on ART. Predictors of LTFU included: lower-than-secondary level education (reference: Tertiary), care in North-East and South-South regions (reference: North-Central), presence of moderate/severe anemia, symptomatic functional status, and baseline weight <45kg. Predictor of mortality was WHO stage higher than stage I. Male sex, severe anemia, and care in a small clinic were associated with both mortality and LTFU.ConclusionModerate/Advanced HIV disease was predictive of attrition; earlier ART initiation could improve program outcomes. Retention interventions targeting men and those with lower levels of education are needed. Further research to understand geographic and clinic size variations with outcome is warranted.

Background:Human immunodeficiency virus positive (HIV+) women have a higher risk of developing invasive cervical cancer compared with uninfected women. This study aims to document programmatic experience of integrating cervical cancer screening using Visual Inspection and Acetic Acid (VIA) into HIV care as well as to describe patients’ characteristics associated with positive VIA findings amongst HIV+ women.Materials and Methods:A cross-sectional study analysed routine service data collected at the antiretroviral therapy (ART) and cervical cancer screening services. Our program integrated screening for cervical cancer using VIA technique to HIV care and treatment services through a combination of stakeholder engagement, capacity building for health workers, creating a bi-directional referral between HIV and reproductive health (RH) services and provider initiated counselling and screening for cervical cancer. Information on patients’ baseline and clinical characteristics were captured using an electronic medical records system and then exported to Statistical Package for the Social Sciences (SPSS). Logistic regression model was used to estimate factors that influence VIA results.Results:A total of 834 HIV+ women were offered VIA screening between April 2010 and April 2011, and 805 (96.5%) accepted it. Complete data was available for 802 (96.2%) women. The mean age at screening and first sexual contact were 32.0 (SD 6.6) and 18.8 (SD 3.5) years, respectively. VIA was positive in 52 (6.5%) women while 199 (24.8%) had a sexually transmitted infection (STI). Of the 199 who had a STI, eight (4.0%) had genital ulcer syndrome, 30 (15.1%) had lower abdominal pain syndrome and 161 (80.9%) had vaginal discharge syndrome. Presence of lower abdominal pain syndrome was found to be a significant predictor of a positive VIA result (P = 0.001). Women with lower abdominal pain syndrome appeared to be more likely (OR 47.9, 95% CI: 4.8-480.4, P = 0.001) to have a positive VIA result.Conclusion:The high burden of both HIV and cervical cancer in developing countries makes it a necessity for integrating services that offer early detection and treatment for both diseases. The findings from our study suggest that integrating VIA screening into the package of care offered to HIV+ women is feasible and acceptable.
