The HI V O pen Call on I nformed C onsent and E thics in Research (VOICE) for Adolescents and Young Adults: A Digital Crowdsourcing Open Call in Low- and Middle-Income Countries.

BACKGROUND: Many adolescents and young adults (AYAs; 10-24 years old) are excluded from HIV research because of social, ethical, and legal challenges with informed consent, resulting in limited AYA-focused data. We use a participatory approach to identify strategies for improving AYA consent processes in HIV research in low- and middle-income countries (LMICs). METHODS: We conducted a digital crowdsourcing open call for ideas to improve AYA consent to HIV research in LMICs. Crowdsourcing involves engaging a group of people in problem-solving, then sharing emergent solutions. Submissions were evaluated by 3 independent judges using predefined criteria, with exceptional strategies receiving prizes. Demographic data were collected, and textual data were qualitatively analyzed for emergent themes in barriers and facilitators for improving AYA consent in HIV research, guided by a socioecological model. RESULTS: We received 110 strategies total; 65 were eligible for evaluation, 25 of which were identified as finalists. Fifty-eight participants from 10 LMICs submitted the 65 eligible submissions, of which 30 (52%) were 18 to 24 years old. Thematic analysis identified 10 barriers to AYA consent, including HIV stigma, limited education, and legal/regulatory barriers. Strategies for improving AYA consent processes revealed 7 potential facilitators: enhancing AYA engagement in research, involving parents/guardians, improving education/awareness, improving institutional practices/policy, making research participation more AYA-friendly, enhancing engagement of other key communities of interest, and empowering AYA. CONCLUSIONS: Diverse communities of interest in LMICs developed compelling strategies to enhance informed consent that may improve AYA inclusion in HIV research. These data will be used to develop practical guidance on improving AYA consent processes.

An Unstructured Supplementary Service Data System to Verify HIV Self-Testing Among Nigerian Youths: Mixed Methods Analysis of Usability and Feasibility.

BACKGROUND: Mobile health (mHealth) interventions among adolescents and young adults (AYAs) are increasingly available in African low- and middle-income countries (LMICs). For example, the unstructured supplementary service data (USSD) could be used to verify HIV self-testing (HIVST) among AYAs with poor bandwidth. OBJECTIVE: The aim of this study is to describe the creation of an USSD platform and determine its feasibility and usability to promote the verification of HIVST results among AYAs in Nigeria. METHODS: We developed and evaluated a USSD platform to verify HIVST results using a user-centered approach. The USSD platform guided AYAs in performing HIVST, interpreting the result, and providing linkage to care after the test. Following the usability assessment, the USSD platform was piloted. We used a mixed methods study to assess the platform's usability through a process of quantitative heuristic assessment, a qualitative think-aloud method, and an exit interview. Descriptive statistics of quantitative data and inductive thematic analysis of qualitative variables were organized. RESULTS: A total of 19 AYAs participated in the usability test, with a median age of 19 (IQR 16-23) years. There were 11 females, 8 males, and 0 nonbinary individuals. All individuals were out-of-school AYAs. Seven of the 10 Nielsen usability heuristics assessed yielded positive results. The participants found the USSD platform easy to use, preferred the simplicity of the system, felt no need for a major improvement in the design of the platform, and were happy the system provided linkage to care following the interpretation of the HIVST results. The pilot field test of the platform enrolled 164 out-of-school AYAs, mostly young girls and women (101, 61.6%). The mean age was 17.5 (SD 3.18) years, and 92.1% (151/164) of the participants reported that they were heterosexual, while 7.9% (13/164) reported that they were gay. All the participants in the pilot study were able to conduct HIVST, interpret their results, and use the linkage to care feature of the USSD platform without any challenge. A total of 7.9% (13/164) of the AYAs had positive HIV results (reactive to the OraQuick kit). CONCLUSIONS: This study demonstrated the usability and feasibility of using a USSD system as an alternative to mobile phone apps to verify HIVST results among Nigerian youth without smartphone access. Therefore, the use of a USSD platform has implications for the verification of HIVST in areas with low internet bandwidth. Further pragmatic trials are needed to scale up this approach.

A multicenter survey of asymptomatic cryptococcal antigenemia among patients with advanced HIV disease in Nigeria.

As of 2018, cryptococcal antigen (CrAg) screening in patients with advanced human immunodeficiency virus (HIV) disease (AHD) was not routinely implemented in Nigeria despite being recommended in the national HIV treatment guidelines. Our aim was to determine the prevalence and risk factors for asymptomatic cryptococcal antigenemia in adult people living with HIV (PLHIV) in Nigeria to advocate for the implementation of routine CrAg screening. A descriptive cross-sectional study and CrAg screening of consecutive adult PLHIV with CD4 counts ≤200 cells/µL was conducted from April 2018 to April 2019 at HIV clinics in eleven tertiary hospitals spread across Nigeria's six geopolitical regions. Prevalence of asymptomatic cryptococcal antigenemia was estimated by facility and geopolitical zone. Logistic regression was conducted to identify risk factors for cryptococcal antigenemia. In total, 1,114 patients with AHD were screened. The overall prevalence of asymptomatic cryptococcal antigenemia was 3.9% with wide variation across facilities (range: 0/75 [0%]- 15/122 [12.3%]) and geopolitical zones (range: 0/75 [0%]-19/279 [6.8%]). Prevalence of antigenemia was highest in the South-West (19/279 [6.8%]) and lowest in the North-East (0/75 [0%]). Prevalence was 5.2% (26/512) and 3.2% (18/561) in patients with CD4<100 and CD4 of 101-200, respectively. Of all patients with antigenemia, 50% were on antiretroviral therapy (ART) at the time of having a positive CrAg test. In adjusted analysis, cryptococcal antigenemia was significantly less in patients on ART and patients who had completed any formal education. The survey showed a high overall burden of cryptococcal antigenemia in Nigeria, with variable prevalence across geopolitical regions. We provided valuable evidence for implementing routine CrAg screening of AHD patients in Nigeria which has commenced in selected centres.

Factors influencing the integration of evidence-based task-strengthening strategies for hypertension control within HIV clinics in Nigeria.

BACKGROUND: Evidence-based task-strengthening strategies for hypertension (HTN) control (TASSH) are not readily available for patients living with HIV in sub-Saharan Africa where the dual burden of HTN and HIV remains high. We are conducting a cluster randomized controlled trial comparing the effectiveness of practice facilitation versus a self-directed control (i.e., receipt of TASSH with no practice facilitation) in reducing blood pressure and increasing the adoption of task-strengthening strategies for HTN control within HIV clinics in Nigeria. Prior to implementing the trial, we conducted formative research to identify factors that may influence the integration of TASSH within HIV clinics in Nigeria. METHODS: This mixed-methods study was conducted with purposively selected healthcare providers at 29 HIV clinics, followed by a 1-day stakeholder meeting with 19 representatives of HIV clinics. We collected quantitative practice assessment data using two instruments: (a) an adapted Service Availability and Readiness Assessment (SARA) tool to assess the capacity of the clinic to manage NCDs and (b) Implementation Climate Scale to assess the degree to which there is a strategic organizational climate supportive of the evidence-based practice implementation. The quantitative data were analyzed using descriptive statistics and measures of scale reliability. We also used the Consolidated Framework for Implementation Research (CFIR), to thematically analyze qualitative data generated and relevant to the aims of this study. RESULTS: Across the 29 clinics surveyed, the focus on TASSH (mean=1.77 (SD=0.59)) and educational support (mean=1.32 (SD=0.68)) subscales demonstrated the highest mean score, with good-excellent internal consistency reliability (Cronbach's alphas ranging from 0.84 to 0.96). Within the five CFIR domains explored, the major facilitators of the intervention included relative advantage of TASSH compared to current practice, compatibility with clinic organizational structures, support of patients' needs, and intervention alignment with national guidelines. Barriers included the perceived complexity of TASSH, weak referral network and patient tracking mechanism within the clinics, and limited resources and diagnostic equipment for HTN. CONCLUSION: Optimizing healthcare workers' implementation of evidence-based TASSH within HIV clinics requires attention to both the implementation climate and contextual factors likely to influence adoption and long-term sustainability. These findings have implications for the development of effective practice facilitation strategies to further improve the delivery and integration of TASSH within HIV clinics in Nigeria.

The 4 Youth By Youth mHealth Photo Verification App for HIV Self-testing in Nigeria: Qualitative Analysis of User Experiences.

BACKGROUND: Despite the global expansion of HIV self-testing (HIVST), many research studies still rely on self-reported outcomes. New HIVST verification methods are needed, especially in resource-limited settings. OBJECTIVE: This study aims to evaluate the user experience of a mobile health (mHealth) app to enhance HIVST result reporting and verification. METHODS: Semistructured, in-depth interviews were used to evaluate the user experience of the 4 Youth By Youth mHealth photo verification app for HIVST. We used a think-aloud approach, and participants performed usability tasks and completed a qualitative exit interview. The app included HIV educational resources, step-by-step video instructions for performing HIVST, a 20-minute timer, a guide on interpreting results with linkages to care, an offline version, and a photo verification system. Demographic characteristics were reported by using descriptive statistics. Qualitative data were analyzed by using thematic analysis. RESULTS: A total of 19 users-12 women and 7 men-with a mean age of 22 years, participated in the study. The users completed the usability tasks and successfully uploaded a photo of their test results by using the app without assistance. Four main themes were identified in the data. First, in terms of user-friendly design, the participants noted the user-friendly features of the offline version and the app's low data use. However, some wanted the app to work in the background when using their mobile phone, and the font used should be more youth friendly. Second, in terms of ease of use, participants remarked that the app's self-explanatory nature and instructions that guided them on how to use the app enhanced its use. Third, in terms of a user's privacy, many participants reinforced the importance of privacy settings and tools that protect confidentiality among users. Finally, in terms of linkage to care, participants noted that the app's linkage to care features were useful, particularly in relation to referrals to trained counselors upon the completion of the test. All the participants noted that the app provided a convenient and private means of verifying the HIV test results. CONCLUSIONS: Our findings demonstrated the importance of engaging end users in the development phase of health technology innovations that serve youth. Clinical trials are needed to determine the efficacy of using an mHealth app to verify HIVST results among young people.

Designing HIV Testing and Self-Testing Services for Young People in Nigeria: A Discrete Choice Experiment.

BACKGROUND AND OBJECTIVE: A third of new human immunodeficiency virus (HIV) infections occur among young people and the majority of young people living with HIV are in sub-Saharan Africa. We examined the strength of Nigerian youth preferences related to HIV testing and HIV self-testing (HIVST). METHODS: Discrete choice experiments were conducted among Nigerian youth (age 14-24 years). Participants completed one of two discrete choice experiments: (1) preferred qualities of HIV testing (cost, location of test, type of test, person who conducts the test, and availability of HIV medicine at the testing site) and (2) preferred qualities of HIVST kits (cost, test quality, type of test, extra items, and support if tested positive). A random parameter logit model measured the strength of preferences. RESULTS: A total of 504 youth participated: mean age 21 years (standard deviation 2 years), 38% male, and 35% had a higher than secondary school education. There was a strong preference overall to test given the scenarios presented, although male individuals were less likely to test for HIV or use HIVST kits. Youth preferred HIV testing services (with attributes in order of importance) that are free, blood-based testing, available in private/public hospitals or home, for HIV medications to be available in the same location as testing, and a doctor conducts the test. Participants preferred HIVST kits (with attributes in order of importance) that are available from community health centers, free, approved by the World Health Organization, include other sexually transmitted infection testing, have the option of an online chat, and oral-based HIVST. CONCLUSIONS: The HIV home testing was equally preferred to testing in a hospital, suggesting a viable market for HIVST if kits account for youth preferences. Male youth were less likely to choose to test for HIV or use HIVST kits, underscoring the need for further efforts to encourage HIV testing among young male individuals.

"Their place is beyond the town's border": A qualitative exploration of stigma associated with tuberculosis in rural and urban areas of Lagos, Nigeria.

Tuberculosis (TB) remains a major public health challenge in Nigeria with a minimum yield of various TB control efforts due to sociocultural determinants of health including TB-associated stigma. Therefore, to achieve the Sustainable Development Goal targets for TB control, an understanding and reduction in TB-associated stigma is necessary. The study aims to explore the perspective of community members and investigate the possible ways of mitigating TB-associated stigma in rural and urban areas in Lagos State, Nigeria. Eight focus group discussions (FGD) were conducted among eight homogenous groups of participants living in the community in rural and urban areas of Lagos state who were stratified by gender, between July and November 2017. Analysis of data was done using the modified grounded theory. A total of 86 participants took part in the FGDs. There were various stigmatising behaviours towards people infected with TB in rural and urban communities studied. This includes: Not willing to eat with people suffering from TB, withdrawal from TB patients in social gatherings, verbal abuse of TB patients and refusing to visit their houses because of their illness. There were also misconceptions about the cause of TB in our study which includes spiritual attack, ingestion of cat hair and inhalation of dust. However, participants in the study believed that mitigating the effect of TB-associated stigma will require adequate community education on TB, provision of financial and emotional support to the patients, as well as the involvement of community leaders in TB control activities and stigma reduction interventions. TB-associated stigma exists in rural and urban communities, with a lack of appropriate knowledge of TB and fear of infection as a major determinant in rural and urban areas respectively. Health education and sensitisation about TB, with community leaders as champions could help to mitigate the effect of TB-associated stigma.

Young people's preferences for HIV self-testing services in Nigeria: a qualitative analysis.

BACKGROUND: HIV self-testing (HIVST) provides young people with a convenient, discreet, and empowering way to know their HIV status. However, there is limited knowledge of young people's preferences for HIVST services and potential factors that may influence the uptake of HIVST among this population. The purpose of this research was to use qualitative methods to examine HIVST preferences among Nigerian youth. METHODS: Semi-structured in-depth interviews with a purposive sample of young people 14-24 years old were conducted in Lagos, Nigeria. Data were analyzed thematically to identify themes and domains related to preferences and factors influencing the use of HIV self-testing. RESULTS: A total of 65 youth with mean age of 21 years, were interviewed, and the majority were females (56%). Four themes emerged as the most important characteristics that may influence young people's preferences for HIV self-testing: 1) Cost (i.e. majority of participants noted that they would pay between NGN500 to NGN1,500 naira (USD1.38-USD4.16) for oral HIV self-testing kits); 2) Testing method (i.e. although blood-based sample kits were more popular than oral-based self-testing kits, most preferred the oral-based option due to its perceived benefits and for some, phobia of needles); 3) Access location (i.e. participants suggested they preferred to obtain the HIVST kits from youth-friendly centers, pharmacies, private health facilities, and online stores); and 4) Continuing care and support (i.e. participants highlighted the importance of linkage to care with trained youth health workers for positive or negative test results or toll-free helpline). CONCLUSION: HIV self-testing preferences among Nigerian youth appear to be influenced by several factors including lower cost, less invasive testing method, location of testing, and linkage to care and support post testing. Findings underscore the need to address young people's HIV self-testing preferences as a foundation for implementing programs and research to increase the uptake of HIVST.

Addressing Stroke Literacy in Nigeria Through Music: A Qualitative Study of Community Perspectives.

BACKGROUND: The incidence of stroke in Nigeria is unknown, but stroke literacy, defined here as awareness of stroke warning symptoms and risk factors may be poor in high-risk communities. Although there is growing recognition of the use of music as a conduit to promote health literacy, African music is often overlooked as a source of health information. We sought to understand community-level perspectives on using African music to promote acute stroke literacy. METHODS: A purposive sample of education, health and music professionals, high school and university students were recruited to participate in the qualitative study. Study participants completed a brainstorming exercise that elicited their perceptions of potential barriers and facilitators to the use of music to promote acute stroke literacy in Nigeria. Content analysis was used to identify key themes emerging from the brainstorming exercise. RESULTS: A total of 44 individuals, comprising of 25 students with a mean age of 15.9 ± 1.6 years (52% females) and 19 professionals with a mean age of 39 ± 7.7 years (57.9% males) participated in the brainstorming exercise. Facilitators to the use of music to promote acute stroke literacy in Nigeria include the cultural relevance of music, the ubiquity of music, and government involvement. Key barriers include religious beliefs that discourage the use of "secular" music, cost-related barriers, and limited government support. CONCLUSIONS: Findings from this study provide guidance aimed at improving acute stroke literacy in Nigeria, particularly the importance of government involvement in the development and implementation of stroke literacy interventions guided by African music. Future work should consider implementing interventions that leverage the cultural elements of African music and further assess the extent to which these identified facilitators and/or barriers may influence stroke literacy.

Nurses' perceptions on implementing a task-shifting/sharing strategy for hypertension management in patients with HIV in Nigeria: a group concept mapping study.

BACKGROUND: People living with HIV (PWH) in Africa have higher burden of cardiovascular diseases (CVD) compared to the general population, probably due to increased burden of hypertension (HTN). In this study, we explored nurses' perceptions of factors that may influence the integration of an evidence-based task-shifting/sharing strategy for hypertension control (TASSH) into routine HIV care in Lagos, Nigeria. METHODS: Using group concept mapping, we examined the perceptions of 22 nurses from HIV clinics in Lagos. Participants responded to a focused prompt on the barriers and facilitators of integrating TASSH into HIV care; next, separate focus groups generated relevant statements on these factors; and statements were then sorted and rated on their importance and feasibility of adoption to create cluster maps of related themes. The statements and cluster maps were categorized according to the Consolidated Framework for Implementation Research (CFIR) domains. RESULTS: All study participants were women and with 2 to 16 years' experience in the provision of HIV care. From the GCM activities, 81 statements were generated and grouped into 12 themes. The most salient statements reflected the need for ongoing training of HIV nurses in HTN management and challenges in adapting TASSH in HIV clinics. A synthesis of the cluster themes using CFIR showed that most clusters reflected intervention characteristics and inner setting domains. The potential challenges to implementing TASSH included limited hypertension knowledge among HIV nurses and the need for on-going supervision on implementing task-shifting/sharing. CONCLUSIONS: Findings from this study illustrate a variety of opinions regarding the integration of HTN management into HIV care in Nigeria. More importantly, it provides critical, evidence-based support in response to the call to action raised by the 2018 International AIDS Society Conference regarding the need to implement more NCD-HIV integration interventions in low-and middle-income countries through strategies, which enhance human resources. This study provides insight into factors that can facilitate stakeholder engagement in utilizing study results and prioritizing next steps for TASSH integration within HIV care in Nigeria.

Capabilities, opportunities and motivations for integrating evidence-based strategy for hypertension control into HIV clinics in Southwest Nigeria.

BACKGROUND: Given the growing burden of cardiovascular diseases in sub-Saharan Africa, global donors and governments are exploring strategies for integrating evidence-based cardiovascular diseases prevention into HIV clinics. We assessed the capabilities, motivations and opportunities that exist for HIV clinics to apply evidence-based strategies for hypertension control among people living with HIV (PLHIV) in Nigeria. METHODS: We used a concurrent Quan-Qual- study approach (a quantitative first step using structured questionnaires followed by a qualitative approach using stakeholder meetings).We invited key stakeholders and representatives of HIV and non-communicable disease organizations in Lagos, Nigeria to 1) assess the capacity of HIV clinics (n = 29) to, and; 2) explore their attitudes and perceptions towards implementing evidence-based strategies for hypertension management in Lagos, Nigeria (n = 19)The quantitative data were analyzed using SPSS whereas responses from the stakeholders meeting were coded and analyzed using thematic approach and an implementation science framework, the COM-B (Capabilities, Opportunities, Motivations and Behavior) model, guided the mapping and interpretation of the data. RESULTS: Out of the 29 HIV clinics that participated in the study, 28 clinics were public, government-owned facilities with 394 HIV patients per month with varying capabilities, opportunities and motivations for integrating evidence-based hypertension interventions within their services for PLHIV. Majority of the clinics (n = 26) rated medium-to-low on the psychological capability domains, while most of the clinics (n = 25) rated low on the physical capabilities of integrating evidence-based hypertension interventions within HIV clinics. There was high variability in the ratings for the opportunity domains, with physical opportunities rated high in only eight HIV clinics, two clinics with a medium rating and nineteen clinics with a low rating. Social opportunity domain tended to be rated low in majority of the HIV clinics (n = 21). Lastly, almost all the HIV clinics (n = 23) rated high on the reflective motivation domain although automatic motivations tended to be rated low across the HIV clinics. CONCLUSION: In this study, we found that with the exception of motivations, the relative capabilities whether physical or psychological and the relative opportunities for integrating evidence-based hypertension intervention within HIV clinics in Nigeria were minimal. Thus, there is need to strengthen the HIV clinics in Lagos for the implementation of evidence-based hypertension interventions within HIV clinics to improve patient outcomes and service delivery in Southwest Nigeria.

Child sexual abuse and disclosure in South Western Nigeria: a community based study.

INTRODUCTION: The true burden of child sexual abuse in Nigeria is not known as most reports are institutional based. This study was designed to determine population level data on the burden and pattern of child sexual abuse among adolescents in South Western Nigeria. METHODS: A community based study among adolescents in SouthWestern Nigeria. Semi- structured interviewer administered questionnaire was used to collect data from respondents selected through a multistage sampling technique. Analysis was with SPSS version 20. RESULTS: 398 adolescents (314 females and 84 males) aged 10-19 years with a mean age of 15.6 ± 2.0 years participated in the study. Most were single (90.7%), in school (84.2%), and lived with their parents/guardians (89.4%). The prevalence of CSA was 25.7%. Penetrative abuse occurred in 7.5%, and forced abuse in 46.2% of cases. Perpetrators were mostly boyfriends (31.2%) and neighbours (16.1%). Intra-familial abuse occurred in 7.5% of cases. Only 34.4% of cases ever disclosed the abuse. CONCLUSION: CSA is common in the community, with perpetrators majorly persons known to the adolescents. A large number of cases are not reported. Efforts should be made to educate children and their parents on various ways to reduce child sexual abuse and its consequences.

Prevalence and impact of sickle cell trait on the clinical and laboratory parameters of HIV infected children in Lagos, Nigeria.

INTRODUCTION: sickle cell disease and HIV infection are prevalent in sub-Saharan Africa. While Haemoglobin S (HbS) contributes to significant morbidity and mortality in the homozygous or double heterozygous states, in the carrier state it confers a survival advantage in disease conditions such as malaria. However the interaction between sickle haemoglobin and HIV infection, especially in children remains largely unknown. This study aimed to assess the prevalence and impact of sickle cell trait on the clinical and laboratory parameters of HIV infected children in Lagos, Nigeria. METHODS: a cross-sectional study among HIV infected children in an HIV treatment centre in Lagos, Nigeria. Socio-demographic and clinical characteristics were obtained and blood sample collected for haemoglobin electrophoresis, HIV RNA viral load and haematologic profile. Data was analysed with SPSS version 20. RESULTS: the prevalence of sickle cell trait was 18.8% among the 208 study participants, with none having sickle cell disease (SCD). Participants with SCT were significantly younger (OR = 4.0 95% CI (1.74-9.24)), more likely to be from the Yoruba ethnic group (OR = 3.3 95% CI [1.45-7.52)), had more opportunistic infections (OR = 2.4 95% CI (1.18-5.03), and lower mean HIV RNA viral load (p = 0.05) at baseline. However response to HIV care and treatment was similar in both groups of participants. CONCLUSION: the finding of absence of SCD, low prevalence of SCT, and lower HIV viraemia in HIV infected children with SCT may have implications for childhood survival which requires further clarification in future studies.

Trends and patterns of sexual assaults in Lagos south-western Nigeria.

INTRODUCTION: Sexual assault is a severely traumatic experience that disproportionally affects women and girls. Yet there is limited information on the subject in our environment. This study was conducted to determine the trend and pattern of sexual assault among Nigerians. METHODS: A retrospective study of sexual assault victims managed at a large clinic in south west Nigeria. Victims were identified from the programme data base and case files retrieved from medical records department. Relevant information was extracted and managed with SPSS for windows version 19. RESULTS: Steady increase in the proportion of reported cases of sexual violence over the years (P < 0.0001) was observed. Sexual assaults were recorded among the males (6.1%), although female victims were in the majority (93.9%). Sexual assault was found to be higher in person's <20 years and the unmarried. Most sexual assault occurred during the day time. Assailants were mostly persons known to the victim (52.0%) and the assault occurred mostly in the assailants' house or office (48.5%). Sexual assault through vaginal route only (87.2%) was the most common route of sexual assault. Threat of violence (31.1%) and physical force (29.6%) was the common methods for overcoming the victims. Follow up was completed by 75.0% of the victims. CONCLUSION: Sexual assault is common in our environment, with increasing prevalence and change in pattern. Young persons aged less than 20 years constitutes the majority of victims and assailants were mostly persons known to them. The current public education on the evils of sexual violence should be intensified.

Evaluation of Direct Visual Inspection of the Cervix in Detecting Cytology Diagnosed Squamous Intraepithelial Lesion in Women of known HIV Status. A Randomized Trial (CANHIV Study).

A two-arm, open label, randomized study, evaluated the test characteristics of visual inspection of cervix with Acetic acid(VIA) and Lugol?s Iodine(VILI) in detecting cytology diagnosed squamous intraepithelial lesion(SIL) in 1160 women of known HIV status in southwestern Nigerian. Using SIL as reference standard and the HIV status masked, VIA and VILI had similar test characteristics except for the positive predictive value in which VIA value of 91.5% was significantly higher than 77.7% for VILI ( p=0.01). Among HIV positive women, VILI performed poorly across all the 4 test characteristics compared to VIA. Among severely immuno-compromised HIV positive participants VILI performance was consistently below 80% across all test characteristics (sensitivity-70.0%; specificity-66.9%; positive predictive value-46.7%; negative predictive value(NPV)-50.0%) compared to VIA (Senstivity-71.3%; specificity-88.2%; positive predictive value-83.3%; negative predictive value -88.2). Our study shows that VILI is insufficiently sensitive and specific in the presence of HIV infection especially in those with severe immunosuppression. Based on VIA?s acceptable sensitivity and NPV in all situations, it is recommended for cervical cancer screening in HIV positive women and in settings of high HIV burden.

Predictors of default from follow-up care in a cervical cancer screening program using direct visual inspection in south-western Nigeria.

BACKGROUND: Increasingly evidence is emerging from south East Asia, southern and east Africa on the burden of default to follow up care after a positive cervical cancer screening/diagnosis, which impacts negatively on cervical cancer prevention and control. Unfortunately little or no information exists on the subject in the West Africa sub region. This study was designed to determine the proportion of and predictors and reasons for default from follow up care after positive cervical cancer screen. METHOD: Women who screen positive at community cervical cancer screening using direct visual inspection were followed up to determine the proportion of default and associated factors. Multivariate logistic regression was used to determine independent predictors of default. RESULTS: One hundred and eight (16.1%) women who screened positive to direct visual inspection out of 673 were enrolled into the study. Fifty one (47.2%) out of the 108 women that screened positive defaulted from follow-up appointment. Women who were poorly educated (OR: 3.1, CI: 2.0 - 5.2), or lived more than 10 km from the clinic (OR: 2.0, CI: 1.0 - 4.1), or never screened for cervical cancer before (OR: 3.5, CI:3:1-8.4) were more likely to default from follow-up after screening positive for precancerous lesion of cervix . The main reasons for default were cost of transportation (48.6%) and time constraints (25.7%). CONCLUSION: The rate of default was high (47.2%) as a result of unaffordable transportation cost and limited time to keep the scheduled appointment. A change from the present strategy that involves multiple visits to a "see and treat" strategy in which both testing and treatment are performed at a single visit is recommended.

Pattern, challenges and correlates of condom use among Nigerians living with HIV infection

<p><b>OBJECTIVE</b>To determine the pattern, challenges and correlates of condom use among Nigerians living with HIV Infection.</p><p><b>METHODS</b>A cross sectional questionnaire study among HIV positive adults attending an HIV treatment centre in Lagos, Nigeria. Data entry and analysis were done with Epi-info version 3.5.1.</p><p><b>RESULTS</b>The mean age of respondents was 35 (SD=7.7; range: 17-58 years) and mean age at sexual debut was 20 years old (range: 7-37 years). Majority were women (66.6%), had at least secondary school education(91.1%), married (68.2%)), on ART (50.7%) and knew their partners HIV status(60.9%). The rate of condom use at last sex act was 65.9%, but only 48.8% used condom consistently. Factors associated with condom use were male gender (OR=2.43, CI=1.35-4.33, P=0.002), less than secondary school education (OR=3.12, CI=1.04-9.28, P=0.05) and Not knowing partner's HIV status (OR=1.90, CI=1.04-3.80, P=0.04). Refusal to use condom (28.4%) were as a result of pregnancy intention, undesirability of condom in marriage and decreased sexual pleasure.</p><p><b>CONCLUSION</b>There is low consistent condom use rate of 48.8% among this cohort despite their exposure to behavioural change messages. A review of the present counselling strategy and combination prevention is therefore advocated.</p>

Incidence of and socio-biologic risk factors for spontaneous preterm birth in HIV positive Nigerian women.

BACKGROUND: Recent studies have identified HIV as a leading contributor to preterm delivery and its associated morbidity and mortality. However little or no information exists in our sub-region on this subject. Identifying the factors associated with preterm delivery in HIV positive women in our country and sub-region will not only prevent mother to child transmission of HIV virus but will also reduce the morbidity and mortality associated with prematurity and low birth weight. This study was designed to determine the incidence and risk factors for preterm delivery in HIV positive Nigerians. METHOD: The required data for this retrospective study was extracted from the data base of a cohort study of the outcome of prevention of mother to child transmission at the Nigerian Institute of Medical Research, Lagos. Only data of women that met the eligibility of spontaneous delivery after 20 weeks of gestation were included. Ethical approval was obtained from the Institution's Ethical Review Board. RESULTS: 181 women out of the 1626 eligible for inclusion into the study had spontaneous preterm delivery (11.1%). The mean birth weight was 3.1 ± 0.4 kg, with 10.3% having LBW. Spontaneous preterm delivery was found to be significantly associated with unmarried status (cOR: 1.7;1.52-2.57), baseline CD4 count <200 cells/mm(3) (cOR: 1.8; 1.16-2.99), presence of opportunistic infection at delivery (cOR: 2.2;1.23-3.57), multiple pregnancy (cOR 10.4; 4.24 - 26.17), use of PI based triple ARV therapy (eOR 10.2; 5.52 - 18.8) in the first trimester (cOR 2.5; 1.77 - 3.52) on univariate analysis. However after multivariate analysis controlling for potential confounding variables including low birth weight, only multiple pregnancy (aOR: 8.6; CI: 6.73 - 12.9), presence of opportunistic infection at delivery (aOR: 1.9; CI: 1.1 - 5.7), and 1st trimester exposure to PI based triple therapy (aOR: 5.4; CI: 3.4 - 7.8) retained their significant association with preterm delivery. CONCLUSION: The spontaneous preterm delivery rate among our cohort was 11.1%. HIV positive women with multiple pregnancies, symptomatic HIV infection at delivery and first trimester fetal exposure to PI based triple therapy were found to be at risk of spontaneous preterm delivery. Early booking and non-use of PI based triple therapy in the first trimester will significantly reduce the risk of preterm delivery.
