Primary caregivers, healthcare workers, teachers and community leaders\u2019 perceptions and experiences of their involvement, practice and challenges of disclosure of HIV status to children living with HIV in Malawi: a qualitative study

BackgroundThe World Health Organisation has recommended that healthcare workers, teachers and community leaders work with parents to support children living with HIV. The aim of this study was to assess the perceptions and experiences of primary caregivers and other care providers such as healthcare workers, teachers, and community leaders regarding their involvement, practice and challenges of HIV disclosure to children aged between 6 and 12 years living with HIV in Malawi.MethodsTwelve focus group discussions and 19 one-on-one interviews involving a total of 106 participants were conducted in all three administrative regions of Malawi. The interviews and focus group discussions explored perceptions and experiences regarding involvement, practice and challenges of disclosure of HIV status to children. Data were analysed using thematic analysis.ResultsPrimary caregivers, healthcare workers, teachers, and community leaders all reported that the disclosure of HIV status to children was not well coordinated because each of the groups of participants was working in isolation instead of working as a team. A “working together” model emerged from the data analysis where participants expressed the need for them to work as a team in order to promote safe and effective HIV status disclosure through talking about HIV, sharing responsibility and open communication. Participants reported that by working together, the team members would ensure that the prevalence of HIV disclosure to young children increases and that there would be a reduction in any negative impact of disclosure.ConclusionGlobal resources are required to better support children living with HIV and their families. Healthcare workers and teachers would benefit greatly from training in working together with families living with HIV and, specifically, training in the disclosure process. Resources, in the form of books and other educational materials, would help them explain HIV and its effective management to children and families.

Design and protocol for a pragmatic randomised study to optimise screening, prevention and care for tuberculosis and HIV in Malawi (PROSPECT Study)

Background: Adults seeking diagnosis and treatment for tuberculosis (TB) and HIV in low-resource settings face considerable barriers and have high pre-treatment mortality. Efforts to improve access to prompt TB treatment have been hampered by limitations in TB diagnostics, with considerable uncertainty about how available and new tests can best be implemented. Design and methods: The PROSPECT Study is an open, three-arm pragmatic randomised study that will investigate the effectiveness and cost-effectiveness of optimised HIV and TB diagnosis and linkage to care interventions in reducing time to TB diagnosis and prevalence of undiagnosed TB and HIV in primary care in Blantyre, Malawi. Participants (≥ 18 years) attending a primary care clinic with TB symptoms (cough of any duration) will be randomly allocated to one of three groups: (i) standard of care; (ii) optimised HIV diagnosis and linkage; or (iii) optimised HIV and TB diagnosis and linkage. We will test two hypotheses: firstly, whether prompt linkage to HIV care should be prioritised for adults with TB symptoms; and secondly, whether an optimised TB triage testing algorithm comprised of digital chest x-ray evaluated by computer-aided diagnosis software and sputum GeneXpert MTB/Rif can outperform clinician-directed TB screening. The primary trial outcome will be time to TB treatment initiation by day 56, and secondary outcomes will include prevalence of undiagnosed TB and HIV, mortality, quality of life, and cost-effectiveness. Conclusions: The PROSPECT Study will provide urgently-needed evidence under “real-life” conditions to inform clinicians and policy makers on how best to improve TB/HIV diagnosis and treatment in Africa.

Adaptation and delivery of a motivational interviewing-based counseling program for persons acutely infected with HIV in Malawi: Implementation and lessons learned

ObjectiveIndividuals diagnosed with acute HIV infection (AHI) are highly infectious and require immediate HIV prevention efforts to minimize their likelihood of transmitting HIV to others. We sought to explore the relevance of Motivational Interviewing (MI), an evidence-based counseling method, for Malawians with AHI. MethodsWe designed a MI-based intervention called “Uphungu Wanga” to support risk reduction efforts immediately after AHI diagnosis. It was adapted from Options and SafeTalk interventions, and refined through formative research and input from Malawian team members and training participants. We conducted qualitative interviews with counselors and participants to explore the relevance of MI in this context. ResultsIntervention adaptation required careful consideration of Malawian cultural context and the needs of people with AHI. Uphungu Wanga's content was relevant and key MI techniques of topic selection and goal setting were viewed positively by counselors and participants. However, rating levels of importance and confidence did not appear to help participants to explore behavior change as intended. ConclusionUphungu Wanga may have provided some added benefits beyond “brief education” standard of care counseling for Malawians with AHI. Practice implicationsMI techniques of topic selection and goal setting may enhance prevention education and counseling for Malawians with AHI.

High self-reported non-adherence to antiretroviral therapy amongst adolescents living with HIV in Malawi: barriers and associated factors.

Introduction: Globally adolescents and young adults account for more than 40% of new HIV infections, and HIV-related deaths amongst adolescents increased by 50% from 2005 to 2012. Adherence to antiretroviral therapy (ART) is critical to control viral replication and preserve health; however, there is a paucity of research on adherence amongst the growing population of adolescents living with HIV/AIDS (ALHIV) in Southern Africa. We examined levels of self-reported ART adherence, barriers to adherence, and factors associated with non-adherence amongst ALHIV in Malawi.Methods: Cross-sectional study of 519 ALHIV (12–18 years) attending two large HIV clinics in central and south-eastern Malawi. Participants self-reported missed doses (past week/month), barriers to adherence, and completed questionnaires on past traumatic events/stressors, disclosure, depression, substance use, treatment self-efficacy, and social support. Biomedical data were retrieved from existing medical records. Multivariate logistic regression was performed to identify factors independently associated with self-reported ART adherence (7 day recall).Results: The mean age of participants (SD) was 14.5 (2) years and 290 (56%) were female. Of the 519 participants, 153 (30%) reported having missed ART doses within the past week, and 234 (45%) in the past month. Commonly reported barriers to adherence included forgetting (39%), travel from home (14%), busy with other things (11%), feeling depressed/overwhelmed (6%), feeling stigmatized by people outside (5%) and within the home (3%). Factors found to be independently associated with missing a dose in the past week were drinking alcohol in the past month (OR 4.96, 95% CI [1.41–17.4]), missed clinic appointment in the past 6 months (OR 2.23, 95% CI [1.43–3.49]), witnessed or experienced violence in the home (OR 1.86, 95% CI [1.08–3.21]), and poor treatment self-efficacy (OR 1.55 95% CI [1.02–2.34]). Sex and age were not associated with adherence.Conclusions: In our study, nearly half of all ALHIV reported non-adherence to ART in the past month. Violence in the home or alcohol use in the past year as well as poor treatment self-efficacy were associated with worse adherence. Sub-optimal adherence is a major issue for ALHIV and compromise treatment outcomes. Programmes specifically tailored to address those challenges most pertinent to ALHIV may help improve adherence to ART.

Persistent misconceptions about HIV transmission among males and females in Malawi.

BackgroundThe prevalence of HIV in Malawi is one of the highest in sub-Saharan Africa, and misconceptions about its mode of transmission are considered a major contributor to the continued spread of the virus.MethodsUsing the 2010 Malawi Demographic and Health Survey, the current study explored factors associated with misconceptions about HIV transmission among males and females.ResultsWe found that higher levels of ABC prevention knowledge were associated with lower likelihood of endorsing misconceptions among females and males (OR = 0.85, p < 0.001; OR = 0.85, p < 0.001, respectively). Compared to those in the Northern region, both females and males in the Central (OR = 0.54, p < 0.001; OR = 0.53, p < 0.001, respectively) and Southern regions (OR = 0.49, p < 0.001; OR = 0.43, p < 0.001, respectively) were less likely to endorse misconceptions about HIV transmission. Moreover, marital status and ethnicity were significant predictors of HIV transmission misconceptions among females but not among males. Also, household wealth quintiles, education, religion, and urban–rural residence were significantly associated with endorsing misconceptions about HIV transmission.ConclusionBased on our findings, we recommend that education on HIV transmission in Malawi should integrate cultural and ethnic considerations of HIV/AIDS.

Comparative cost-effectiveness of Option B+ for prevention of mother-to-child transmission of HIV in Malawi.

To estimate the cost-effectiveness of prevention of mother-to-child transmission (MTCT) of HIV with lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women ('Option B+') compared with ART during pregnancy or breastfeeding only unless clinically indicated ('Option B'). Mathematical modelling study of first and second pregnancy, informed by data from the Malawi Option B+ programme. Individual-based simulation model. We simulated cohorts of 10 000 women and their infants during two subsequent pregnancies, including the breastfeeding period, with either Option B+ or B. We parameterized the model with data from the literature and by analysing programmatic data. We compared total costs of antenatal and postnatal care, and lifetime costs and disability-adjusted life-years of the infected infants between Option B+ and Option B. During the first pregnancy, 15% of the infants born to HIV-infected mothers acquired the infection. With Option B+, 39% of the women were on ART at the beginning of the second pregnancy, compared with 18% with Option B. For second pregnancies, the rates MTCT were 11.3% with Option B+ and 12.3% with Option B. The incremental cost-effectiveness ratio comparing the two options ranged between about US$ 500 and US$ 1300 per DALY averted. Option B+ prevents more vertical transmissions of HIV than Option B, mainly because more women are already on ART at the beginning of the next pregnancy. Option B+ is a cost-effective strategy for PMTCT if the total future costs and lost lifetime of the infected infants are taken into account.

Group B streptococcus vaccination in pregnant women with or without HIV in Africa: a non-randomised phase 2, open-label, multicentre trial

SummaryBackgroundNeonates born to women infected with HIV are at increased risk for invasive group B streptococcus (GBS) disease. We aimed to compare safety and immunogenicity of trivalent glycoconjugate GBS vaccine in pregnant women with and without HIV in Malawi and South Africa.MethodsIn our non-randomised phase 2, open-label, multicentre study, we recruited pregnant women attending two antenatal clinics, one in Blantyre, Malawi, and one in Soweto, Johannesburg, South Africa. Participants were divided into three groups on the basis of their HIV infection status (no infection, infection and high CD4 cell count [>350 cells per μL], and infection and low CD4 cell count [>50 to ≤350 cells per μL]) and received a 5 μg dose of glycoconjugate GBS vaccine (serotypes Ia, Ib, and III, with CRM197 [Novartis Vaccines, Siena, Italy]) intramuscularly at 24–35 weeks' gestation. GBS serotype-specific antibody concentrations were measured before vaccination (day 1), day 15, day 31, and at delivery, and in infants at birth and day 42 of life. The primary outcomes were safety in mothers and infants and the amount of placental transfer of GBS serotype-specific antibodies from mothers to their infants. All immunogenicity and safety analyses were done on the full analysis set, including participants who, or whose mother, correctly received the vaccine and who provided at least one valid assessable serum sample. This study is registered with ClinicalTrials.gov, number NCT01412801.Findings270 women and 266 infants were enrolled between Sept 26, 2011, and Dec 4, 2012 (90 women and 87 infants without HIV, 89 and 88 with HIV and high CD4 cell counts, and 91 and 91 with HIV and low CD4 cell counts, respectively). Seven women were lost to follow-up, six withdrew consent, one died, and two relocated. Eight infants died or were stillborn and two were lost to follow-up. Across serotypes, fold change in antibody concentrations were higher for the HIV-uninfected group than the HIV-infected groups. Transfer ratios were similar across all three groups (0·49–0·72; transfer ratio is infant geometric mean antibody concentration in blood collected within 72 h of birth divided by maternal geometric mean antibody concentration in blood collected at delivery); however, at birth, maternally derived serotype-specific antibody concentrations were lower for infants born to women infected with HIV (0·52–1·62 μg/mL) than for those born to women not infected with HIV (2·67–3·91 μg/mL). 151 (57%) of 265 women reported at least one solicited adverse reaction: 39 (45%) of 87 women with HIV and low CD4 cell counts, 52 (59%) of 88 women with HIV and high CD4 cell counts, and 60 (67%) of 90 women in the HIV-uninfected group. 49 (18%) of 269 women had at least one adverse event deemed possibly related to the vaccine (six [7%] in the HIV and low CD4 cell count group, 12 [13%] in the HIV and high CD4 cell count group, and 21 [23%] in the HIV-uninfected group), as did three (1%) of 266 neonates (zero, two [1%], and one [1%]); none of these events was regarded as serious.InterpretationThe vaccine was less immunogenic in women infected with HIV than it was in those not infected, irrespective of CD4 cell count, resulting in lower levels of serotype-specific maternal antibody transferred to infants, which could reduce vaccine protection against invasive GBS disease. A validated assay and correlate of protection is needed to understand the potential protective value of this vaccine.FundingNovartis Vaccines and Diagnostics division (now part of the GlaxoSmithKline group of companies), Wellcome Trust UK, Medical Research Council: Respiratory and Meningeal Pathogens Research Unit.

Self-efficacy in protecting oneself against HIV transmission

This article deals with the complexity of health behaviour from a self-efficacy perspective, and shows the naivety in assuming knowledge as the main guide to better protection against HIV. The authors accentuate the importance of local knowledge when developing health strategies as in the case of protection against HIV, in this case for female university students in Malawi. Being part of a transition period, these students have to handle complex and at times opposing expectations. This makes HIV protection into a complex social- and health issue. However, the close association between universities and rational thinking has for long made public health see self-efficacy as one of the main determinants in general health behaviour. By seeing health behaviour as complex, this study explores into how female university students perceive their own self-efficacy in protecting themselves against HIV in Malawi with a HIV score of approximately 12%. The study is based on data from Chancellor College in Zomba, Malawi. The authors point to the potential of a closer collaboration between social work and public health in issues of both a social and a health nature, as in the case of HIV protection.

Factors associated with depression among adolescents living with HIV in Malawi.

BackgroundPrior research suggests that a high prevalence of depression, with a detrimental impact on treatment outcomes exists among HIV-infected youth. Data on potential risk factors of depression among HIV-infected youth in sub-Saharan Africa are scarce. This cross-sectional study aimed to identify contributory/protective factors associated with depression in Malawian adolescents 12–18 years old living with HIV.MethodsDepression was measured by a validated Chichewa version of the Beck Depression Inventory version-II (BDI-II) and the Children’s Depression Rating Scale-Revised (CDRS-R). Data on variables thought to potentially be contributory/protective were collected and included: socio-demographics, past traumatic events/stressors, behavioural factors/social support, and bio-clinical parameters. Chi-square test or two-sample t-test was used to explore associations between factors and depression. Additional testing via linear/logistic regression, adjusting for age and sex, identified candidate variables (p < 0.1). Final regression models included variables with significant main effects and interactions.ResultsOf the 562 participants enrolled (mean age, 14.5 years [SD 2.0]; 56.1 % female), the prevalence of depression was 18.9 %. In multivariate linear regression, the variables significantly associated with higher BDI-II score were female gender, fewer years of schooling, death in the family/household, failing a school term/class, having a boyfriend/girlfriend, not disclosed or not having shared one’s HIV status with someone else, more severe immunosuppression, and bullied for taking medications. Bullying victimization was reported by 11.6 % of respondents. We found significant interactions: older participants with lower height-for-age z-scores and dissatisfied with their physical appearance had higher BDI-II scores. In multivariate logistic regression, factors significantly associated with depression were: older age, OR 1.23 (95 % CI 1.07-1.42); fewer years of schooling, OR 3.30 (95 % CI 1.54-7.05); and bullied for taking medications, (OR 4.20 (95 % CI 2.29-7.69).ConclusionHaving fewer years of schooling and being bullied for taking medications were most clearly associated with depression. Programmes to support the mental health needs of HIV-infected adolescents that address issues such as disclosure, educational support, and, most notably, bullying may improve treatment outcomes and are recommended.

Evaluation of postpartum HIV superinfection and mother-to-child transmission.

This study examined HIV superinfection in HIV-infected women postpartum, and its association with mother-to-child transmission (MTCT). Plasma samples were obtained from HIV-infected women who transmitted HIV to their infants after 6 weeks of age (transmitters, n = 91) and HIV-infected women who did not transmit HIV to their infants (nontransmitters, n = 91). These women were originally enrolled in a randomized trial for prevention of MTCT of HIV in Malawi (Post-Exposure Prophylaxis of Infants trial in Malawi). Two HIV genomic regions (p24 and gp41) were analyzed by next-generation sequencing for HIV superinfection. HIV superinfection was established if the follow-up sample contained a new, phylogenetically distinct viral population. HIV superinfection and transmission risk were examined by multiple logistic regression, adjusted for Post-Exposure Prophylaxis of Infants study arm, baseline viral load, baseline CD4 cell count, time to resumption of sex, and breastfeeding duration. Transmitters had lower baseline CD4 cell counts (P = 0.001) and higher viral loads (P < 0.0001) compared with nontransmitters. There were five cases of superinfection among transmitters (rate of superinfection = 4.7/100 person-years) compared with five cases among the nontransmitters (rate of superinfection = 4.4/100 person-years; P = 0.78). HIV superinfection was not associated with increased risk of postnatal MTCT of HIV after controlling for maternal age, baseline viral load, and CD4 cell count (adjusted odds ratio = 2.32, P = 0.30). Longer breastfeeding duration was independently associated with a lower risk of HIV superinfection after controlling for study arm and baseline viral load (P = 0.05). There was a significant level of HIV superinfection in women postpartum, but this was not associated with an increased risk of MTCT via breastfeeding.

Drug resistance mutations 18 months after discontinuation of nevirapine-based ART for prevention of mother-to-child transmission of HIV in Malawi.

The objective of this study was to determine the prevalence of drug resistance mutations among HIV-positive women in Malawi 18 months after discontinuing nevirapine-based ART for the prevention of mother-to-child transmission. HIV-infected antiretroviral-naive (except for single-dose nevirapine) pregnant Malawian women receiving a nevirapine-based triple antiretroviral regimen from Week 25 of gestation until 6 months of breastfeeding were included in this analysis. Drug resistance was assessed in HIV-DNA 24 months post-partum and at baseline (before the initiation of treatment). In patients with resistance, the presence of mutations was also evaluated in the corresponding plasma samples. Seven out of 42 (16.7%) women studied had archived drug resistance at Month 24 [six cases had NNRTI-associated mutations and two cases the M184I mutation]. In four cases, resistance mutations were already present at baseline (all NNRTI mutations). In three cases, there was an emergence of 'new' resistance (also present in the plasma in one case). Of the 35 women without resistance mutations at Month 24, only one subject had resistance mutations at baseline. Baseline resistance was significantly more common among women with mutations at 24 months compared with those harbouring a WT virus (4/7 versus 1/35, P < 0.001). Among women who had discontinued drugs 6 months post-partum, only 3/42 (7.1%) had accumulated new resistance mutations in HIV-DNA 2 years after delivery. These findings are reassuring in terms of the safety of the Option B strategy for the prevention of HIV mother-to-child transmission.

Preferences for food and nutritional supplements among adult people living with HIV in Malawi.

To elucidate the factors influencing food intake and preferences for potential nutritional supplements to treat mild and moderate malnutrition among adult people living with HIV (PLHIV). Qualitative research using in-depth interviews with a triangulation of participants and an iterative approach to data collection. The study was conducted in a health clinic of rural Chilomoni, a southern town of Blantyre district, Malawi. Male and female participants, aged 18-49 years (n 24), affected by HIV; health surveillance assistants of Chilomoni clinic (n 8). Six themes emerged from the in-depth interviews: (i) PLHIV perceived having a poor-quality diet; (ii) health challenges determine the preferences of PLHIV for food; (iii) liquid-thick, soft textures and subtle natural colours and flavours are preferred; (iv) preferred organoleptic characteristics of nutritional supplements resemble those of local foods; (v) food insecurity may contribute to intra-household sharing of nutritional supplements; and (vi) health surveillance assistants and family members influence PLHIV's dietary behaviours. No differences by sex were found. The emergent themes were corroborated by health surveillance assistants through participant triangulation. In this setting, a thickened liquid supplement, slightly sweet and sour, may be well accepted. A combination of quantitative and qualitative methods for data collection should follow to further develop the nutritional supplement and to fine tune the organoleptic characteristics of the product to the taste and requirements of PLHIV. Results of the present study provide a first approach to elucidate the factors influencing food intake and preferences for potential nutritional supplements among adult PLHIV.

Profiles of Risk for HIV/AIDS Among Young Malawian Adults: Understanding Behavioral Intentions

Young adults are especially vulnerable to HIV and engage in sexual activities that expose them to the HIV virus. Although into a third decade of HIV/AIDS epidemic, few studies have examined the heterogeneity in the population of young adults at risk for HIV in Malawi. This study utilizes a Latent Class Analysis method to identify profiles of young adults at most risk for contracting HIV/AIDS to include: High Risk and At-Risk. A Chi squared test was used to determine whether class membership was associated with reported changes in sexual behavior to avoid HIV. The results indicate that of young adults who report to change their behaviors, 61.4 % were in the At-Risk Group, whereas 38.6 % were in the High Risk Group. We conclude that practice and policy measures that involve High Risk Group would be beneficial. This group would benefit from additional interventions encouraging them to change their sexual behaviors. Results from this study highlight the importance of identifying profiles of culturally formed attitudes, beliefs, and norms as a step towards targeting interventions that may decrease the prevalence of HIV/AIDS among young adults.

The information experience and learning needs of couples living with HIV in Malawi.

In this feature, guest writer Kondwani Wella presents an overview of his PhD - a study which investigated the information experience of serodiscordant couples with HIV and AIDS in Malawi. In particular, for this article, he considers the information behaviour of people who need HIV- and AIDS-specific information and the role of the librarian in helping to deliver what is needed to support engagement in relevant learning.

Mental health of carers of children affected by HIV attending community-based programmes in South Africa and Malawi

There is strong evidence that both adults and children infected with and affected by HIV have high levels of mental health burden. Yet there have been few studies investigating carer mental health outcomes in the context of HIV in Malawi and South Africa. The objective of this study was to assess the mental health of carers of children affected by HIV as a part of the Child Community Care study, which aims to generate evidence on the effectiveness of community-based organisation (CBO) services to improve child outcomes. In a cross-sectional study, we interviewed 952 carers of children (aged 4–13 years) attending 28 randomly selected CBOs funded by 11 major donors in South Africa and Malawi. Psychological morbidity was measured using the Shona Symptom Questionnaire and suicidal ideation was measured using an item from the Patient Health Questionnaire. Carers were asked about care-seeking for emotional problems. Overall, 28% of carers scored above the clinical cut-off for current psychological morbidity and 12.2% reported suicidal ideation. We used logistic regression models to test factors associated with poor outcomes. Household unemployment, living with a sick family member and perceived lack of support from the community were associated with both psychological morbidity and suicidal ideation in carers. Reported child food insecurity was also associated with psychological morbidity. In addition, carers living in South Africa were more likely to present with psychological morbidity and suicidal ideation than carers in Malawi. Rates of help-seeking for mental health problems were low. Carers of children affected by HIV are at risk for mental health problems as a result of HIV, socio-economic, care-giving and community factors. We call for increased recognition of the potential role of CBOs in providing mental health care and support for families as a means to improve equity in mental health care. Specifically, we highlight the need for increased training and supervision of staff at CBOs for children affected by HIV, and the inclusion of CBOs in broader efforts to improve population mental health outcomes.

“Without the grandparents, life is difficult”: Social hierarchy and therapeutic trajectories for children living with HIV in rural Northern Malawi

Since 2008 children infected with HIV in Malawi have had access to free adult fixed-dose combination antiretroviral treatment (ART). After four years, more than 33,000 children now have access to these life-saving medicines and the chance to transition into adolescence. However, little is known about the lived reality of growing up HIV positive in resource poor contexts and the long term therapeutic efficacy of ART regimens remain mostly speculative (Mills et al., 2011). Drawing on two years of ethnographic fieldwork conducted at a rural hospital and with HIV positive children on treatment in Malawi, I examine the daily grind within households trying to raise healthy children in precarious circumstances. While most service delivery organizations base their understandings of children's care on the model of the “family” or the “household”, I argue that they need to consider more seriously the ways that everyday social relationships in specific contexts shape long term treatment success for children. To that end, I propose that Janzen's (1978) concept of the “therapy management group” (TMG), is a more accurate, fluid and inclusive way to think about the care and treatment of children living with HIV. By drawing on specific treatment trajectories I explore how gendered and intergenerational dynamics influence the timing of HIV treatment initiation, the ability to find “good food” for children on treatment and how high mortality rates among elderly and HIV positive caregivers can both impede and promote early diagnosis and treatment adherence. Findings from this research will help pediatric and adolescent HIV care and treatment services develop community based approaches to the long term care and treatment of infected children by highlighting how important it is to avoid preconceived conceptions about how child care works in specific settings.

Maternal Antiretroviral Therapy for the Prevention of Mother-To-Child Transmission of HIV in Malawi: Maternal and Infant Outcomes Two Years after Delivery

BackgroundOptimized preventive strategies are needed to reach the objective of eliminating pediatric AIDS. This study aimed to define the determinants of residual HIV transmission in the context of maternal antiretroviral therapy (ART) administration to pregnant women, to assess infant safety of this strategy, and to evaluate its impact on maternal disease.Methodology/Principal FindingsA total of 311 HIV-infected pregnant women were enrolled in Malawi in an observational study and received a nevirapine-based regimen from week 25 of gestation until 6 months after delivery (end of breastfeeding period) if their CD4+ count was > 350/mm3 at baseline (n = 147), or indefinitely if they met the criteria for treatment (n. 164). Mother/child pairs were followed until 2 years after delivery. The Kaplan-Meier method was used to estimate HIV transmission, maternal disease progression, and survival at 24 months. The rate of HIV infant infection was 3.2% [95% confidence intervals (CI) 1.0-5.4]. Six of the 8 transmissions occurred among mothers with baseline CD4+ count > 350/mm3. HIV-free survival of children was 85.8% (95% CI 81.4-90.1). Children born to mothers with baseline CD4+ count < 350/mm3 were at increased risk of death (hazard ratio 2.6, 95% CI 1.1-6.1). Among women who had stopped treatment the risk of progression to CD4+ count < 350/mm3 was 20.6% (95% CI 9.2-31.9) by 18 months of drug discontinuation.ConclusionsHIV transmission in this cohort was rare however, it occurred in a significative proportion among women with high CD4+ counts. Strategies to improve treatment adherence should be implemented to further reduce HIV transmission. Mortality in the uninfected exposed children was the major determinant of HIV-free survival and was associated to maternal disease stage. Given the considerable proportion of women reaching the criteria for treatment within 18 months of drug discontinuation, life-long ART administration to HIV-infected women should be considered.

P6.039 Why Did Plausible Research Evidence Fail to Inform Policy? A Lesson from Male Circumcision Evidence on Efficacy For the Prevention of HIV in Malawi

<h3></h3> On the basis of three randomised controlled trials showing that male circumcision (MC) is effective in reducing HIV transmission, WHO/UNAIDS recommend that high HIV prevalence countries include MC in their HIV prevention programmes. Malawi delayed to adopt such a policy. This study examines evidence-to-policy processes in Malawi, using MC as a case study. Separate but similar semi-structured interviews were conducted with national health policy decision-makers, researchers, politicians and traditional leaders regarding the decision-making processes concerning the adoption of MC and, as a comparison, to the adoption of acyclovir for management of STIs and nevirapine for PMTCT. We observed that although policy-makers are aware of the evidence in Sub-Saharan Africa that MC reduces the risk of HIV acquisition among circumcised men, the adoption of a MC policy is resisted. Policy-makers and international actors are embroiled in policy controversies that have historical resonance in Malawi; MC is perceived as something that comes from outside-–a Western ‘imposition’ is being forced onto Malawians. Malawi was settled by Muslims and by non-circumcised Christians; ethnic and religious rivalries have characterised politics since Independence. Thus, politicians have framed MC in-terms of tribal and religious identities. In contrast, acyclovir and nevirapine were perceived as culturally neutral, and were accepted without debate. The call for evidence-based policy is likely to be received as unproblematic when, as with acyclovir and nevirapine, the issue does not touch controversies especially those related to religion and ethnic politics. But, when a core issue that identifies ethnicities is at the centre of controversy and it threatens what powerful local actors consider being in their best interest – there is invariably opposition. Thus <i>reframing </i>a new policy to minimise controversy – and in the case of MC, from “MC” to “voluntary medical MC” might result in actors’ reflection and thus provide a path towards resolution.
