Rwanda 20 years on: investing in life

Two decades ago, the genocide against the Tutsis in Rwanda led to the deaths of 1 million people, and the displacement of millions more. Injury and trauma were followed by the effects of a devastated health system and economy. In the years that followed, a new course set by a new government set into motion equity-oriented national policies focusing on social cohesion and people-centred development. Premature mortality rates have fallen precipitously in recent years, and life expectancy has doubled since the mid-1990s. Here we reflect on the lessons learned in rebuilding Rwandas health sector during the past two decades, as the country now prepares itself to take on new challenges in health-care delivery.

Shared learning in an interconnected world: innovations to advance global health equity

The notion of “reverse innovation”--that some insights from low-income countries might offer transferable lessons for wealthier contexts--is increasingly common in the global health and business strategy literature. Yet the perspectives of researchers and policymakers in settings where these innovations are developed have been largely absent from the discussion to date. In this Commentary, we present examples of programmatic, technological, and research-based innovations from Rwanda, and offer reflections on how the global health community might leverage innovative partnerships for shared learning and improved health outcomes in all countries.

HIV-free survival among nine- to 24-month-old children born to HIV-positive mothers in the Rwandan national PMTCT programme: a community-based household survey

BackgroundOperational effectiveness of large-scale national programmes for the prevention of mother to child transmission (PMTCT) of HIV in sub-Saharan Africa remains limited. We report on HIV-free survival among nine- to 24-month-old children born to HIV-positive mothers in the national PMTCT programme in Rwanda.MethodsWe conducted a national representative household survey between February and May 2009. Participants were mothers who had attended antenatal care at least once during their most recent pregnancy, and whose children were aged nine to 24 months. A two-stage stratified (geographic location of PMTCT site, maternal HIV status during pregnancy) cluster sampling was used to select mother-infant pairs to be interviewed during household visits. Alive children born from HIV-positive mothers (HIV-exposed children) were tested for HIV according to routine HIV testing protocol. We calculated HIV-free survival at nine to 24 months. We subsequently determined factors associated with mother to child transmission of HIV, child death and HIV-free survival using logistic regression.ResultsOut of 1448 HIV-exposed children surveyed, 44 (3.0%) were reported dead by nine months of age. Of the 1340 children alive, 53 (4.0%) tested HIV positive. HIV-free survival was estimated at 91.9% (95% confidence interval: 90.4-93.3%) at nine to 24 months. Adjusting for maternal, child and health system factors, being a member of an association of people living with HIV (adjusted odds ratio: 0.7, 95% CI: 0.1-0.995) improved by 30% HIV-free survival among children, whereas the maternal use of a highly active antiretroviral therapy (HAART) regimen for PMTCT (aOR: 0.6, 95% CI: 0.3-1.07) had a borderline effect.ConclusionsHIV-free survival among HIV-exposed children aged nine to 24 months is estimated at 91.9% in Rwanda. The national PMTCT programme could achieve greater impact on child survival by ensuring access to HAART for all HIV-positive pregnant women in need, improving the quality of the programme in rural areas, and strengthening linkages with community-based support systems, including associations of people living with HIV.

High Risk of ART Non-Adherence and Delay of ART Initiation among HIV Positive Double Orphans in Kigali, Rwanda

Background To reduce HIV/AIDS related mortality of children, adherence to antiretroviral treatment (ART) is critical in the treatment of HIV positive children. However, little is known about the association between ART adherence and different orphan status. The aims of this study were to assess the ART adherence and identify whether different orphan status was associated with the child’s adherence. Methods A total of 717 HIV positive children and the same number of caregivers participated in this cross-sectional study. Children’s adherence rate was measured using a pill count method and those who took 85% or more of the prescribed doses were defined as adherent. To collect data about adherence related factors, we also interviewed caregivers using a structured questionnaire. Results Of all children (N = 717), participants from each orphan category (double orphan, maternal orphan, paternal orphan, non-orphan) were 346, 89, 169, and 113, respectively. ART non-adherence rate of each orphan category was 59.3%, 44.9%, 46.7%, and 49.7%, respectively. The multivariate analysis indicated that maternal orphans (AOR 0.31, 95% CI 0.12–0.80), paternal orphans (AOR 0.35, 95% CI 0.14–0.89), and non-orphans (AOR 0.45, 95% CI 0.21–0.99) were less likely to be non-adherent compared to double orphans. Double orphans who had a sibling as a caregiver were more likely to be non-adherent. The first mean CD4 count prior to initiating treatment was 520, 601, 599, and 844 (cells/ml), respectively (p<0.001). Their mean age at sero-status detection was 5.9, 5.3, 4.8, and 3.9 (year old), respectively (p<0.001). Conclusions Double orphans were at highest risk of ART non-adherence and especially those who had a sibling as a caregiver had high risk. They were also in danger of initiating ART at an older age and at a later stage of HIV/AIDS compared with other orphan categories. Double orphans need more attention to the promote child’s adherence to ART.

Effect of selenium supplementation on CD4+ T-cell recovery, viral suppression and morbidity of HIV-infected patients in Rwanda: a randomized controlled trial

Objective:To examine the effect of selenium supplementation on CD4+ T-cell counts, viral suppression, and time to antiretroviral therapy (ART) initiation in ART-naive HIV-infected patients in Rwanda. Methods:A multicenter, double-blinded, placebo-controlled, randomized clinical trial was conducted. Eligible patients were HIV-infected adults (≥21 years) who had a CD4+ cell count between 400 and 650 cells/&mgr;l (ART eligibility was ⩽350 cells/&mgr;l throughout the trial), and were willing to practice barrier methods of birth control. Patients were randomized to receive once-daily 200 &mgr;g selenium tablets or identical placebo. They were followed for 24 months with assessments every 6 months. Declines in CD4+ cell counts were modeled using linear regressions with generalized estimating equations and effect modification, and the composite outcome (ART eligible or ART initiation) using Cox proportional-hazards regression, both conducted with intention to treat. Results:Of the 300 participants, 149 received selenium, 202 (67%) were women, and median age was 33.5 years. The rate of CD4+ depletion was reduced by 43.8% [95% confidence interval (CI) 7.8–79.8% decrease] in the treatment arm – from mean 3.97 cells/&mgr;l per month to mean 2.23 cells/&mgr;l per month. We observed 96 composite outcome events – 45 (47%) in the treatment arm. We found no treatment effect for the composite outcome (hazard ratio 1.00, 95% CI 0.66–1.54) or viral suppression (odds ratio 1.18, 95% CI 0.71–1.94). The trial was underpowered for the composite outcome due to a lower-than-anticipated event rate. Adverse events were comparable throughout. Conclusions:This randomized clinical trial demonstrated that 24-month selenium supplementation significantly reduces the rate of CD4+ cell count decline among ART-naive patients.

What makes orphans in Kigali, Rwanda, non-adherent to antiretroviral therapy? Perspectives of their caregivers

Every year, approximately 260,000 children are infected with HIV in low‐ and middle‐income countries. The timely initiation and high level of maintenance of antiretroviral therapy (ART) are crucial to reducing the suffering of HIV‐positive children. We need to develop a better understanding of the background of childrens ART non‐adherence because it is not well understood. The purpose of this study is to explore the background related to ART non‐adherence, specifically in relation to the orphan status of children in Kigali, Rwanda.

Effect of selenium supplementation on CD4 T-cell recovery, viral suppression, morbidity and quality of life of HIV-infected patients in Rwanda: study protocol for a randomized controlled trial

BackgroundLow levels of serum selenium are associated with increased risk of mortality among HIV+ patients in East Africa. We aim to assess the effect of selenium supplementation on CD4 cell count, HIV viral load, opportunistic infections, and quality of life in HIV-infected patients in Rwanda.Methods and DesignA 24-month, multi-centre, patient and provider-blinded, randomized, placebo-controlled clinical trial involving 300 pre-antiretroviral therapy (ART) HIV-infected patients will be carried out at two sites in Rwanda. Patients ≥ 21 years of age with documented HIV infection, CD4 cell count of 400-650 cells/mm3, and not yet on ART will be recruited. Patients will be randomized at each study site using a randomized block design to receive either the selenium micronutrient supplement or an identically appearing placebo taken once daily. The primary outcome is a composite of time from baseline to reduction of CD4 T lymphocyte count below 350 cells/mm3 (confirmed by two measures at least one week apart), or start of ART, or the emergence of a documented CDC-defined AIDS-defining illness. An intention-to-treat analysis will be conducted using stepwise regression and structural equation modeling.DiscussionMicronutrient interventions that aim to improve CD4 cell count, decrease opportunistic infections, decrease HIV viral load, and ultimately delay initiation of more costly ART may be beneficial, particularly in resource-constrained settings, such as sub-Saharan Africa. Additional trials are needed to determine if micro-supplementation can delay the need for more costly ART among HIV-infected patients. If shown to be effective, selenium supplementation may be of public health importance to HIV-infected populations, particularly in sub-Saharan Africa and other resource-constrained settings.Trial RegistrationNCT01327755

How do you circumcise a nation? The Rwandan case study

Voluntary medical male circumcision has been conclusively demonstrated to reduce the lifetime risk of male acquisition of HIV. The strategy has been adopted as a component of a comprehensive strategy towards achieving an AIDS-free generation. A number of countries in which prevalence of HIV is high and circumcision is low have been identified as a priority, where innovative approaches to scale-up are currently being explored. Rwanda, as one of the priority countries, has faced a number of challenges to successful scale-up. We discuss here how simplifications in the procedure, addressing a lack of healthcare infrastructure and mobilizing resources, and engaging communities of both men and women have permitted Rwanda to move forward with more optimism in its scale-up tactics. Examples from Rwanda are used to highlight how these barriers can and should be addressed.

Design, testing, and scale-up of medical devices for global health: negative pressure wound therapy and non-surgical male circumcision in Rwanda

Products with high efficacy and low cost are desirable in all market sectors and environments, particularly in settings where resources are limited. The health sectors of developing nations are an example of this basic economic principle as constrained financial and human resources must be budgeted toward large (and often, growing) populations’ health needs. However, the cost and quality characteristics that are absolutely necessary in resource-limited settings (RLS) remain highly desirable in wealthy markets as well. Consequently, technologies and strategies designed in RLS are frequently adopted by high-income nations, a process termed “reverse innovation” [1-4]. In recent years, some medical and surgical devices designed for RLS have been adopted by high-income nations. These reverse innovations have simultaneously overcome historical barriers to medical device deployment in RLS and challenged previously held assumptions regarding the direction of information transfer between high- and low-income nations. The potential for reverse innovation has subsequently been proposed as a reason in and of itself to develop products for RLS [4]. Products that result in reverse innovation offer improved care quality and treatment outcomes at lower costs to health care systems, expand markets for manufacturers, promote bidirectional transfer of information, and strengthen global partnerships for health equity [1-4]. One country that has made investments in myriad health innovations is Rwanda, a landlocked East African nation of approximately 12 million. Within the past two decades, Rwanda’s limited resources and diverse health care needs have combined to produce health care innovations ranging from community-based service delivery pathways to novel vaccine roll-out strategies [5-10]. Rwanda’s innovative approaches to seemingly insurmountable health challenges, and the nation’s resounding successes in these initiatives, have been described in a previous article in this Globalization and Health special series [2]. In the present article, we describe our experience with medical device innovation in Rwanda through two case studies, highlighting approaches taken to accelerate development and facilitate bidirectional flow of information. We also discuss ongoing challenges to progress in the field of health technology innovation for RLS. In sharing our experiences, we add our voices to the call for health technology innovation for low- and middle-income countries (LMICs).

Caring for perinatally HIV-infected children: call for mental care for the children and the caregivers

ABSTRACT Antiretroviral therapy has dramatically improved the survival rate of perinatally HIV-infected children. For them to thrive, it is necessary to understand better their mental health issues. Caregivers play an important role in children’s daily care and caregiver mental health may relate to children’s mental health. However, this association has rarely been studied. Accordingly, the present study examined the associations between depression of caregivers and that of perinatally HIV-infected children in Kigali, Rwanda. We conducted a cross-sectional study of 475 perinatally HIV-infected children aged 7–14 years and their caregivers. We collected children’s depression score data via face-to-face interviews with children using the Beck Depression Inventory for Youth. We also collected sociodemographic data using a semi-structured questionnaire with caregivers. In addition, we measured children’s weight, height, and collected their clinical records. Data were analyzed via linear and logistic regression analyses. Of all children, 22% had symptoms of depression. Among those who had depressive symptoms (n= 105), 49% had never received psychological support. In both the linear and logistic regression analysis, caregiver’s high depression scores were positively associated with children’s higher depression scores (AOR: 3.064, 95% CI: 1.723, 4.855, and AOR: 1.759, 95% CI: 1.129, 2.740, respectively). Taking Efavirenz and low height-for-age were also positively associated with higher depression scores among HIV-infected children. Mental health needs to be addressed to improve quality of life of perinatally HIV-infected children. Caregiver’s depression was positively associated with children’s depressive symptoms. Caring for both children and the caregivers’ mental health may prevent the mutual fostering of depression.
