BACKGROUND Few effective community-based interventions exist to increase HIV testing and uptake of antiretroviral therapy (ART) in pregnant women in hard-to-reach resource-limited settings. We assessed whether delivery of an intervention through churches, the Healthy Beginning Initiative, would increase uptake of HIV testing in pregnant women compared with standard health facility referral. METHODS In this cluster randomised trial, we enrolled self-identified pregnant women aged 18 years and older who attended churches in southeast Nigeria. We randomised churches (clusters) to intervention or control groups, stratified by mean annual number of infant baptisms (<80 vs ≥80). The Healthy Beginning Initiative intervention included health education and on-site laboratory testing implemented during baby showers in intervention group churches, whereas participants in control group churches were referred to health facilities as standard. Participants and investigators were aware of church allocation. The primary outcome was confirmed HIV testing. This trial is registered with ClinicalTrials.gov, identifier number NCT 01795261. FINDINGS Between Jan 20, 2013, and Aug 31, 2014, we enrolled 3002 participants at 40 churches (20 per group). 1309 (79%) of 1647 women attended antenatal care in the intervention group compared with 1080 (80%) of 1355 in the control group. 1514 women (92%) in the intervention group had an HIV test compared with 740 (55%) controls (adjusted odds ratio 11·2, 95% CI 8·77-14·25; p<0·0001). INTERPRETATION Culturally adapted, community-based programmes such as the Healthy Beginning Initiative can be effective in increasing HIV screening in pregnant women in resource-limited settings.

BackgroundA total of 22 priority countries have been identified by the WHO that account for 90% of pregnant women living with HIV. Nigeria is one of only 4 countries among the 22 with an HIV testing rate for pregnant women of less than 20%. Currently, most pregnant women must access a healthcare facility (HF) to be screened and receive available prevention of mother-to-child HIV transmission (PMTCT) interventions. Finding new approaches to increase HIV testing among pregnant women is necessary to realize the WHO/ Presidents Emergency Plan for AIDS Relief (PEPFAR) goal of eliminating new pediatric infections by 2015.MethodsThis cluster randomized trial tests the comparative effectiveness of a congregation-based Healthy Beginning Initiative (HBI) versus a clinic-based approach on the rates of HIV testing and PMTCT completion among a cohort of church attending pregnant women. Recruitment occurs at the level of the churches and participants (in that order), while randomization occurs only at the church level. The trial is unblinded, and the churches are informed of their randomization group. Eligible participants, pregnant women attending study churches, are recruited during prayer sessions. HBI is delivered by trained community health nurses and church-based health advisors and provides free, integrated on-site laboratory tests (HIV plus hemoglobin, malaria, hepatitis B, sickle cell gene, syphilis) during a church-organized ‘baby shower.’ The baby shower includes refreshments, gifts exchange, and an educational game show testing participants’ knowledge of healthy pregnancy habits in addition to HIV acquisition modes, and effective PMTCT interventions. Baby receptions provide a contact point for follow-up after delivery. This approach was designed to reduce barriers to screening including knowledge, access, cost and stigma. The primary aim is to evaluate the effect of HBI on the HIV testing rate among pregnant women. The secondary aims are to evaluate the effect of HBI on the rate of HIV testing among male partners of pregnant women and the rate of PMTCT completion among HIV-infected pregnant women.DiscussionResults of this study will provide further understanding of the most effective strategies for increasing HIV testing among pregnant women in hard-to-reach communities.Trial RegistrationClinicaltrials.gov, NCT01795261

Background:Although used globally, little data exist on the efficacy of nevirapine (NVP) used in combination with tenofovir (TDF)/emtricitabine or lamivudine (XTC), and no large randomized prospective control trials exists comparing this combination with efavirenz (EFV)/TDF/(XTC). Methods:As part of the AIDSRelief program, a retrospective review of patient medical chart information along with a cross-sectional viral load, and adherence measurement was conducted between 2004 and 2009. An on-treatment analysis excluded patients who died, transferred out of care, or were lost to follow-up. A switch of antiretrovirals for any reason was considered a failure in the intent-to-treat analysis. Patients with only clinically relevant reasons for switching such as toxicity, adverse effects, viral failure or clinical/immunological failure, lost to follow-up, and death were considered failures as part of the modified-intent-to-treat analysis. Step-wise multiple regression analysis was used to identify variables that were associated with viral suppression. Results:A random sample of 3862 patients met criteria and were included in this analysis. In the on-treatment analysis, older age (P < 0.004) and baseline CD4 <100 cells per cubic millimeter (P < 0.021) were the most significant variables impacting viral load. Patients on TDF/XTC/EFV achieved higher rates of viral suppression compared with patients on TDF/XTC/NVP or azidothymidine (AZT)/lamivudine (3TC)/NVP. Conclusion:Our data show that patients on TDF/XTC/EFV had better outcomes than patients on TDF/XTC/NVP, AZT/3TC/EFV, or AZT/3TC/NVP. High rates of virologic suppression seen in patients on this regimen are consistent with previous studies and indicate the need to increase use of this regimen in HIV programs to promote sustainable viral suppression over time.

BackgroundCurrently, Nigeria alone accounts for 30% of the burden of mother-to-child transmission of HIV. This review explores the socio-cultural factors influencing prevention of mother-to-child transmission of HIV (PMTCT) service uptake in Nigeria.MethodsUsing the PEN-3 cultural model as a guide, we searched electronic databases and conducted a synthesis of empirical studies conducted from 2001 to 2013 that reported the perceptions people have towards PMTCT, the enablers/resources that influence PMTCT service uptake, and the role of nurturers/family or community in shaping actions and decisions towards PMTCT service uptake.ResultsA total of 42 articles meeting the search criteria were retained in this review. Thirty-six (36) were quantitative cross-sectional surveys; three were mixed methods, while three were qualitative studies. The findings highlight that there are perceptions, ranging from positive to negative that influence PMTCT service uptake in Nigeria. Furthermore, lack of available, accessible, acceptable, and affordable resources negatively influence decisions and actions towards PMTCT. Finally, family contexts matter with decisions and actions towards PMTCT service uptake in Nigeria particularly with disclosure and non-disclosure of sero-positive status, fertility intentions and infant feeding choices.ConclusionAs ambitious goals are established and unprecedented resources deployed towards the elimination of mother-to-child transmission of HIV globally by 2015, there is clearly a need to develop effective family-oriented, culture-centered community-based PMTCT programs in Nigeria so as to improve the low uptake of PMTCT services.

To combat morbidity and mortality from the worldwide epidemic of the human immunodeficiency virus (HIV), the United States Congress implemented a Presidents Emergency Plan for AIDS Relief (PEPFAR) in 30 resource-limited countries to integrate combination antiretroviral therapy (ART) for both prevention and cure. Over 35% of eligible persons have been successfully treated. Initial legislation cited palliative care as an essential aspect of this plan but overall health strengthening became critical to sustainability of programing and funding priorities shifted to assure staffing for care delivery sites; laboratory and pharmaceutical infrastructure; data collection and reporting; and financial management as individual countries are being encouraged to assume control of in-country funding. Given infrastructure requisites, individual care delivery beyond ART management alone has received minimal funding yet care remains necessary for durable viral suppression and overall quality of life for individuals. Technical assistance staff of one implementing partner representing seven African countries met to clarify domains of palliative care compared with the substituted term “care and support” to understand potential gaps in on-going HIV care. They prioritized care needs as: 1) mental health (depression and other mood disorders); 2) communication skills (age-appropriate disclosure of HIV status); 3) support of care-providers (stress management for sustainability of a skilled HIV workforce); 4) Tied Priorities: symptom management in opportunistic infections; end-of-life care; spiritual history-taking; and 5) Tied Priorities: attention to grief-related needs of patients, their families and staff; and management of HIV co-morbidities. This process can inform health policy as funding transitions to new priorities.

Siberry

Background:In 2013, Nigeria accounted for 15% of the 1.3 million pregnant women living with HIV in sub-Saharan Africa and 26% of new infections among children worldwide. Despite this, less than 20% of pregnant women in Nigeria received an HIV test during pregnancy, and only 23% of HIV-infected pregnant women received appropriate intervention following HIV diagnosis. This article reports findings from 2 structured group exercises conducted at the first Nigeria Implementation Science Alliance Conference to identify (1) barriers and research gaps related to prevention of mother-to-child transmission (PMTCT) and (2) potential strategies and interventions that could address PMTCT challenges. Methods:Two 1-hour structured group exercises were conducted with 10 groups of 14–15 individuals (n = 145), who were asked to brainstorm barriers and strategies and to rank their top 3 in each category. Data analysis eliminated duplicate responses and categorized each of the priorities along the HIV care continuum: HIV diagnosis, linkage to care, or retention in care. Results:Participating stakeholders identified 20 unique barriers and research gaps related to PMTCT across the HIV continuum. Twenty-five unique interventions and implementation strategies were identified. Similar to the barriers and research gaps, these interventions and strategies were distributed across the HIV care continuum. Conclusions:The barriers and strategies identified in this study represent important pathways to progress addressing MTCT. The deliberate involvement of state and federal policy makers, program implementers, and researchers helps ensure that they are relevant and actionable.

Common mental disorders are prevalent in Nigeria. Due to stigma and a limited number of trained specialists, only 10% of adults with mental illness in Nigeria receive any care. The Healthy Beginning Initiative is a community-based maternal/child health program that includes screening for perinatal depression and was implemented by lay, volunteer, church-based health advisors (CHAs). The aim of the study was to assess the beliefs and attitudes about mental illness among the CHAs. The study used a cross-sectional survey of 57 CHAs, who completed a 43-item, self-administered questionnaire that assessed their beliefs and attitudes about mental illness. The response rate was 71%. Respondents were mostly female (79%), married (83%) and aged 40–49 years (M = 41.16 SD = 10.48). Most endorsed possession by evil spirits (84%), traumatic events (81%) and witchcraft (60%) as causes of mental illness. A majority (69%) believed that people with mental illness were a nuisance, and less than half (46%) believed that mental disorders were illnesses like any other illness. It is concluded that stigmatizing attitudes and beliefs about mental illness are common among the CHAs. Training for lay health workers in Nigeria should include education on the known bio-psycho-social basis of mental disorders and the role of social inclusion in recovery.

Background:In 2014, Nigeria accounted for 33% of all new childhood HIV infections that occurred among the 22 Global Plan priority countries where 80% of HIV-infected women reside. Even with a vertical HIV transmission rate of 27%, only 6% of infants born to HIV-infected women in Nigeria receive early infant diagnosis (EID). This article reports rates of antiretroviral prophylaxis, EID, and mother-to-child transmission in a congregation-based Healthy Beginning Initiative (HBI) designed to increase HIV testing among pregnant women in southeast Nigeria. Methods:This is a nested cohort study of HIV-exposed infants (HEI) within the HBI trial originally designed as a 2-arm cluster randomized trial. HIV-infected mothers and infants were followed between January 2013 and August 2014. Results:Across both arms of the study, 72 HIV-infected women delivered 69 live infants (1 set of twins) and 4 had miscarriages. Of the 69 live-born HEI, HIV status was known for 71% (49/69), 16% (11/69) died before sample collection, and 13% (9/69) were lost to follow-up. Complete information was available for 84% of HEI (58/69), of which 64% (37/58) received antiretroviral prophylaxis. Among the 49 infants tested for HIV, 88% (43/49) received EID within 2 months and 12% (6/49) received antibody testing after 18 months. The mother-to-child transmission rate was 8.2% (4/49). Conclusions:EID was higher and HIV transmission rate was lower among the HBI participants compared to reported rates in 2014. However, further progress is needed to achieve goals of elimination of infant HIV infection.

In many low-income countries, volunteer health advisors (VHAs) play an important role in disseminating information, especially in rural or hard-to-reach locations. When the world’s largest outbreak of Ebola virus disease (EVD) occurred in 2014, a majority of cases were concentrated in the West African countries of Guinea, Liberia, and Sierra Leone. Twenty cases were reported in Nigeria initially and there was a need to rapidly disseminate factual information on Ebola virus. In southeast Nigeria, a group of VHAs was being used to implement the Healthy Beginning Initiative [HBI], a congregation based intervention to increase HIV testing among pregnant women and their male partners. The purpose of this study was to assess the baseline and post EVD training knowledge of VHAs during the outbreak in Nigeria. In September 2014, 59 VHAs attending a HBI training workshop in the Enugu State of Nigeria participated in an Ebola awareness training session. Participants completed a 10-item single-answer questionnaire that assessed knowledge of Ebola epidemiology, symptoms, transmission, prevention practices, treatment and survival prior to the Ebola awareness training. After the training, the VHAs repeated the questionnaire. Answers to pre and post questionnaires were analyzed using paired t-tests. Multiple linear regression was used to examine the relationship between pre and post total questionnaire scores and age, education, current location and employment. The average pre-test score was 7.3 and average post-test score was 7.8 which was a significant difference (t=-2.5, p=0.01). Prior to the training, there was a significant difference in Ebola knowledge based on the VHAs education only (p<0.01). After training, education was no longer significant for Ebola knowledge. Existing community health programs can be used as a platform to train VHAs in times of epidemics for quick dissemination of vital health information in areas lacking adequate health infrastructure and personnel.

Nigeria is second in the world for the number of people with HIV and has a high rate of mother-to-child transmission (MTCT). Over 60% of births in Nigeria occur outside of health care facilities, and because of this, Traditional Birth Attendants (TBAs) play a significant role in maternal and child health. It is important that TBAs be knowledgeable about HIV prevention. The purpose of this study was to determine the impact of HIV testing and counseling (HTC) knowledge on the HIV prevention practices among TBAs in Nigeria. Five hundred TBAs were surveyed. Chi-square and logistic regression were used to assess differences in HIV prevention practices between TBAs with and without HTC knowledge. TBAs with HTC knowledge are significantly more likely to engage in HIV prevention practices than TBAs without HTC. Prevention practices included: wearing gloves during delivery (p < 0.01), sterilization of delivery equipment (p < 0.01), participation in blood safety training (p < 0.01), and disposal of sharps (p < 0.01). As long as a high percent of births occur outside health care facilities in Nigeria, there will be a need for TBAs. Providing TBAs with HTC training increases HIV prevention practices and can be a key to improve maternal and child health.
