BackgroundEffective Prevention of Mother to child Transmission of HIV (PMTCT) relies heavily on follow-up of HIV-infected women and infants from antenatal, through postnatal, to the end of the breastfeeding period. In Uganda, postnatal (PNC) follow-up remains below 50 % creating a missed opportunity for linkage to comprehensive HIV care and early infant diagnosis (EID). We evaluated the use of HIV infected peer mothers (peers), community lay persons and Village health team (VHT) members to improve PNC follow up and EID in urban and rural health units.MethodsStudy participants were HIV-infected women recruited from antenatal clinics at three urban clinics (Mulago, Rubaga and Mengo hospitals) and one rural health centre (Mpigi Health centre IV) between January and September 2010. The women were followed through delivery and the mother-infant pairs for the 6-week postnatal visit and up to 14 weeks for EID. Peers, community lay persons and VHT members were identified and trained in basic PMTCT and reproductive health (RH). They were then assigned to study clinic to support and follow study participants, their partners and infants through provision of health education, counseling, home visits, and phone call reminders. Six week PNC attendance was measured as a proportion of mother-infant pairs that returned for the 6-week postnatal follow up visit (5–8 weeks) while EID was measured as the proportion of HIV-exposed live birth that had an HIV test done by 14 weeks of age. Data at baseline (one year before the intervention) was compared with that during the one year study period among study participants and HIV infected women and their HIV-exposed infants in the whole clinic population.ResultsA total of 558 HIV-infected pregnant women were recruited for the study, 47 mother-infant pairs were censured before 6 weeks due to stillbirth (14), infant death < 6 weeks (23), death of participant (04) and loss to follow up before delivery (6). 401/511 (78.5 %) of mother-infant pairs returned to the study clinics at six-week, while 441/511 (86.3 %) infants were tested for HIV infection by 14 weeks of age. The baseline six-week PNC follow up was 37.7 % and increased during the study period to 78.5 % and 39.1 % among study participants and whole clinic population respectively, an incremental difference of 39.4 % (P < 0.001). EID increased from a baseline of 53.6 % to 86.3 % and 65.8 % among study and whole clinic population respectively during the study period, an incremental difference of 20.5 % (P < 0.001).ConclusionsUse of peers, community lay persons and VHT members led to a significant increase in six-week postnatal follow up of HIV infected women and EID among HIV exposed infants in the four study clinics. Our study supports the use of peers to improve early postnatal follow up and EID and should be implemented in other health units to support the PMTCT cascade.

Background The ‘Primary HIV Prevention among Pregnant and Lactating Ugandan Women’ (PRIMAL) study aimed to assess the effectiveness of an enhanced HIV counseling intervention for preventing HIV acquisition among HIV-uninfected mothers during pregnancy and throughout the breastfeeding period. Methods We conducted an unblinded randomized control trial between 22 February 2013 and 22 April 2016 to assess the effectiveness of an extended repeat HIV testing and enhanced counseling (ERHTEC) intervention aimed at preventing primary HIV infection among HIV-uninfected pregnant and lactating women in Uganda. HIV-uninfected pregnant women aged 15–49 were enrolled 1:1 individually or in couples together with their partner. Enrolled women and couples were randomized 1:1 to an intervention (ERHTEC) or control (extended repeat HIV testing and standard counseling) group and followed up to 24 months postpartum or six weeks past complete cessation of breastfeeding, whichever came first. Both groups were tested for sexually transmitted infections (STIs) and HIV at enrollment, delivery, 3 and 6 months postpartum and every 6 months thereafter until the end of follow-up. The intervention group received enhanced HIV prevention counseling every 3 months throughout follow-up. The control group received standard counseling at the time of HIV retesting. Both intervention and control couples were offered couple HIV testing and counseling at all study visits. Main outcome measures Frequency of condom use and incidence of HIV, syphilis, gonorrhea, chlamydia and trichomoniasis over follow-up. Results Between February 2013 and April 2014, we enrolled 820 HIV-uninfected pregnant women presenting for antenatal care individually (n = 410) or in couples (n = 410 women and 410 partners) in one urban and one rural public Ugandan hospital. Women’s median age was 24 years (IQR 20–28 years). At baseline, participants did not differ in any socio-demographic, reproductive health, HIV testing history, sexual behavior, medical history or STI status characteristics; 96% (386/402) of couples were tested and counseled for HIV together with their partners at enrolment, 2.1% (7/329) of whom were found to be HIV-infected. Six hundred twenty-five (76%) women completed follow-up as per protocol ( S1 Protocol ). Women were followed for an average of 1.76 years and cumulated 1,439 women-years of follow-up or 81% of the maximum 1,779 women-years of follow-up assuming no dropouts. Men were followed for an average of 1.72 years. The frequency of consistent condom use and the proportion of women who used condoms over the last 3 months or at last vaginal sex increased substantially over follow-up in both arms, but there were no statistically significant differences in increases between the intervention and control arms. During follow-up, on average 42% (range 36%-46%) of couple partners were counseled together. Betwe...

Findings indicate low rates of infant infection for mothers receiving combination ARVs. These findings demonstrate that provision of combination ARV for PMTCT is feasible and effective in busy referral hospital's PMTCT programs in resource-limited settings.

Background Viral load (VL) testing is key in monitoring adherence to antiretroviral therapy (ART) and documenting HIV treatment response. As per HIV treatment guidelines in Uganda, the first VL test is recommended 6 months after initiation of ART. Undetectable VL (uVL) at ART initiation may be helpful in detecting elite controllers in the absence of previous ART use. We investigated viral suppression at ART initiation among a cohort of HIV-positive pregnant women enrolled in the Friends for Life Circles (FLC) for Option B+ randomized controlled trial (RCT). Methods Pregnant women ≥ 18 years of age testing positive for HIV at their first antenatal care visit and starting on ART Option B+ as per the National PMTCT Program guidelines were enrolled into the FLC for Option B+ RCT in urban Kampala and rural Mityana districts of Uganda. Each participant had whole blood samples collected at enrolment to assess baseline VL. Plasma HIV-1 RNA was quantified using COBAS Ampliprep /COBAS Taqman. Baseline VL below 400 RNA copies/ml was considered as viral suppression while baseline VL below 20 RNA copies/ml was considered uVL. Results The mean duration from the date of ART initiation to time of sample collection for baseline VL assessment was 4.4 days (SD 3.6). Of the 532 HIV-positive pregnant women enrolled in the FLC for Option B+ study and newly starting Option B+ without a self-reported history of prior ART use, 29 (5.5%) had uVL and 113 (21.4%) had suppressed VL at baseline. There was no association between participants’ age, gravidity, marital status, mean monthly income, educational level, disclosure of HIV status to partner, and uVL or viral suppression at baseline. However, non-disclosure of HIV status to any other person was associated with decreased odds of viral suppression at baseline (OR 0.640; 0.416–0.982). Conclusion Twenty-one percent of HIV-positive Ugandan pregnant women initiating ART (Option B+) showed virological suppression at baseline and were presumed to be “elite controllers” or to have misreported being ART-naive. Further studies are needed to better understand the biologic mechanisms of elite controllers among pregnant women as well as to differentiate elite controllers from concealed ART use. Trial Registration The trial was registered as NCT02515370 (04/08/2015) on Clinicaltrials.gov.

Background: Over 90% of new paediatric HIV infections are acquired through mother to child transmission. Prevention of mother to child HIV transmission (PMTCT) research in sub-Saharan Africa informed WHO guidelines which enabled implementation of PMTCT programs globally. Objectives: To describe Makerere University-Johns Hopkins University (MU-JHU) perinatal HIV prevention research and implementation of the Mulago National Referral Hospital (MNRH) PMTCT program. Methods: Perinatal HIV prevention studies conducted at MU-JHU between 1997–2016 were summarized. Program aggregated data was extracted and analyzed using STATA 15. Results: In 1999, the HIVNET 012 study demonstrated that single-dose nevirapine (sdNVP) to the mother at onset of labor and to her newborn, reduced MTCT by nearly 50%. In 2016, the PROMISE study documented the safety and efficacy of ART during pregnancy and breastfeeding period. Program implementation at MNRH started in 2000. Uptake of HIV testing increased from 70% to 99% from 2006 onwards. sd NVP was the initial ARV regimen but by 2012, MOH recommended Option B+(triple therapy). MTCT rates reduced from 16.9% in 2001 to 2.3% in 2020. Conclusion: Perinatal HIV prevention clinical trials conducted at MU-JHU provided evidence to inform WHO PMTCT guidelines. MNRH program evaluation demonstrated the significant decline in MTCT rates over the last two decades. Keywords: PMTCT Research; PMTCT Program; sub-Saharan Africa.

BackgroundIn 2012, Makerere University Johns - Hopkins University, and Mulago National Referral Hospital, with support from the National Institute of Health (under Grant number: NOT AI-01-023) undertook operational research at Mulago National Hospital PMTCT/PNC clinics. The study employed Peer Family Planning Champions to offer health education, counselling, and triage aimed at increasing the identification, referral and family planning (FP) uptake among HIV positive mothers attending the clinic.MethodsThe Peer Champion Intervention to improve FP uptake was introduced into Mulago Hospital PMTCT/PNC clinic, Kampala Uganda. During the intervention period, peers provided additional FP counselling and education; assisted in identification and referral of HIV Positive mothers in need of FP services; and accompanied referred mothers to FP clinics. We compiled and compared the average proportions of mothers in need that were referred and took up FP in the pre-intervention (3 months), intervention (6 months), and post-intervention(3 months) periods using interrupted time series with segmented regression models with an autoregressive term of one.ResultsOverall, during the intervention, the proportion of referred mothers in need of FP increased by 30.4 percentage points (P < 0.001), from 52.7 to 83.2 percentage points. FP uptake among mothers in need increased by over 31 percentage points (P < 0.001) from 47.2 to 78.5 percentage points during the intervention. There was a positive non-significant change in the weekly trend of referral β3 = 2.9 percentage points (P = 0.077) and uptake β3 = 1.9 percentage points (P = 0.176) during the intervention as compared to the pre-intervention but this was reversed during the post intervention. Over 57% (2494) mothers took up Depo-Provera injectable-FP method during the study.ConclusionsTo support overstrained health care work force in post-natal clinics, peers in trained effective family planning can be a valuable addition to clinic staff in limited-resource settings. The study provides additional evidence on the utilization of peer mothers in HIV care, improves health services uptake including family planning which is a common practice in many donor supported programs. It also provides evidence that may be used to advocate for policy revisions in low-income countries to include peers as support staff especially in busy clinic settings with poor services uptake.Electronic supplementary materialThe online version of this article (doi:10.1186/s12913-017-2386-x) contains supplementary material, which is available to authorized users.

Abstractobjectives To determine and compare the clinical and immunologic outcomes for HIV-infected women initiated on antiretroviral therapy (ART), with and without previous exposure to single-dose nevirapine in the MTCT-Plus programme -Kampala, Uganda, from 2003 to 2011.methods Retrospective comparison of prospectively collected programmatic data of clinical and immunologic treatment outcomes among HIV-infected Ugandan women, with and without prior exposure to sdNVP, who received NNRTI-based ART for a median follow-up of 6 years.results Of the 408 women in the programme, 289 (70.8%) were started on ART, of whom 205 (70.9%) had prior exposure to sdNVP. Clinical, immunologic and combined (clinical and or immunologic) treatment failure occurred in 29 (10.0%), 132 (45.7%) and 142 (49.1%) women, respectively. There was no significant difference in the distribution of time to immunologic failure for women by exposure to sdNVP (log-rank P = 0.98). In Cox proportional hazard modelling, exposure to sdNVP was not associated with immunologic failure [adjusted hazard ratio (HR) = 0.89, 95% confidence interval (CI): 0.61-1.30]. CD4 count >100 cells/mm 3 at initiation was associated with reduced incidence of immunologic failure in adjusted analyses (HR = 0.32, 95% CI: 0.22-0.48).conclusions HIV-infected Ugandan women initiated on an NVP-based ART regimen had similar immunologic treatment outcomes irrespective of previous NVP exposure. CD4 cell count prior to initiating HAART was a key prognostic factor for successful long-term immunologic treatment outcomes. In poor settings, regular follow-up of patients on HAART with adequate counselling to promote adherence and safe disclosure may promote low clinical failure rates.

Background HIV status awareness is critical for HIV prevention and care but HIV testing rates remain low in Uganda, especially among men. One suggested approach to increase access and utilisation of HIV testing services is HIV self-testing. We explored perceptions of pregnant and lactating women and their male partners who attended antenatal care, and health care providers in a government hospital in Kampala, Uganda, about HIV self-testing for initial or repeat testing for women and their partners during pregnancy and postpartum We draw implications for scaling-up this new testing approach in Uganda. Methods This was a qualitative study conducted at Mulago National Referral Hospital, Kampala, Uganda, between April and December 2017. We conducted in-depth interviews with five pregnant or lactating women and their five male partners; five focus group discussions (two with women, two with health workers and one with male partners of women attending antenatal care) and five key informant interviews with health workers providing prevention of mother-to-child HIV transmission (PMTCT) services. Data were analysed using content thematic approach. Results There was limited awareness about HIV self-testing especially among pregnant or lactating women and their male partners. Study participants mentioned that HIV self-testing would enable people to know their HIV status faster, they thought the approach would be cost- and time-saving compared to health facility-based HIV testing, improve confidentiality and reduce stigma for those who test HIV positive. They expressed however, a general fear that HIV self-testing would lead to harm to self and others in case one tested HIV positive, including suicide, violence among couples, intentional transmission of HIV, and limited linkage to care due to lack of counselling. The likely misinterpretation of HIV test results especially among those with no or limited education, and possible coercion exerted by male partners on their wives were other potential concerns raised about the use of HIV self-testing. Conclusions There was limited knowledge about HIV self-testing among pregnant and lactating women, their partners and health workers. While the self-testing modality was perceived to be critical for helping people, especially those in casual and distant relationships, to know their HIV status and that of their partners, most study participants believed that HIV self-testing could potentially result in a multitude of negative outcomes in the absence of pre- and post-test counselling. Successful scale-up and integration of self-testing in HIV programs requires community education, provision of information materials and making self-test kits accessible and affordable, especially in rural areas.
