High rates of undiagnosed and uncontrolled hypertension upon a screening campaign in rural Rwanda: a cross-sectional study.

Background: Hypertension remains the major risk factor for cardiovascular diseases (CVDs) worldwide with a prevalence and mortality in low- and middle-income countries (LMICs) among the highest. The early detection of hypertension risk factors is a crucial pillar for CVD prevention.

Design And Method: This cross-sectional study included 4284 subjects, mean age 46 ± 16SD, 56.

Exploring contextual factors influencing the implementation of evidence-based care for hypertension in Rwanda: a cross-sectional study using the COACH questionnaire.

Importance: Hypertension is the largest contributor to the Global Burden of Disease. In Rwanda, as in most low-income and middle-income countries, an increasing prevalence of hypertension and its associated morbidity and mortality is causing major healthcare and economic impact. Understanding healthcare systems context in hypertension care is necessary.

The TDR MOOC training in implementation research: evaluation of feasibility and lessons learned in Rwanda.

Background: Hypertension (HTN) affects nearly 1 billion people globally and is a major cause of morbidity and mortality. In low- and middle-income countries (LMICs), HTN represents an unmet health care gap that can be addressed by strengthening national health care systems. The National Heart, Lung, and Blood Institute recently funded the T4 Translation Research Capacity Building Initiative in Low Income Countries (TREIN) program to build capacity in dissemination and implementation (D&I) research in HTN in LMICs.

Knowledge about modifiable risk factors for non-communicable diseases adults living with HIV in Rwanda.

Background: Non-communicable diseases (NCD) are of international public health concern. Of more concern are people living with HIV (PLHIV), who have the increased risk of developing NCDs, such as hypertension, stroke and diabetes. Research has revealed that there is a relationship between knowledge of NCD risk factors and risk perceptions in the general population.

Dissemination and Implementation Program in Hypertension in Rwanda: Report on Initial Training and Evaluation.

Background: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide and in low- and middle-income countries, and hypertension (HTN) is a major risk factor for CVD. Although effective evidence-based interventions for control of HTN in high-income countries exist, implementation of these in low- and middle-income countries has been challenging due to limited capacity and infrastructure for late-phase translational research. In Rwanda, the 2015 STEPS NCD (STEPwise Approach to Surveillance of Noncommunicable Diseases) risk survey reported an overall prevalence of HTN of 15% (95% confidence interval [CI]: 13.

Health-related quality of life and associated factors in adults living with HIV in Rwanda.

In Rwanda, as in other sub-Saharan African (SSA) countries, life expectancy of people living with HIV (PLWH) has increased dramatically as a result of combined antiretroviral therapy (cART). People living with HIV can now live longer but with increasing rates of non-communicable diseases (NCDs). Thus, prevention of NCD comorbidities in PWLHI is crucial to maintain and gain health-related benefits and to maximise the health-related quality of life (HRQOL) in the long-term management of PLWH.

HIV treatment is associated with a two-fold higher probability of raised triglycerides: Pooled Analyses in 21 023 individuals in sub-Saharan Africa.

Background: Anti-retroviral therapy (ART) regimes for HIV are associated with raised levels of circulating triglycerides (TG) in western populations. However, there are limited data on the impact of ART on cardiometabolic risk in sub-Saharan African (SSA) populations.

Methods: Pooled analyses of 14 studies comprising 21 023 individuals, on whom relevant cardiometabolic risk factors (including TG), HIV and ART status were assessed between 2003 and 2014, in SSA.

Use of Traditional Botanical Medicines During Pregnancy in Rural Rwanda.

Objective: To evaluate the perceptions of healthcare and traditional medicine providers regarding the type, indications, side effects, and prevalence of traditional medicine use amongst pregnant women in a rural Rwandan population.

Methods: Six focus groups with physicians, nurses, and community health workers and four individual in-depth interviews with traditional medicine providers were held. Qualitative data was gathered using a structured questionnaire querying perceptions of the type, indications, side effects, and prevalence of use of traditional medicines in pregnancy.

HIV Malaria Co-Infection Is Associated with Atypical Memory B Cell Expansion and a Reduced Antibody Response to a Broad Array of Plasmodium falciparum Antigens in Rwandan Adults.

HIV infected individuals in malaria endemic areas experience more frequent and severe malaria episodes compared to non HIV infected. This clinical observation has been linked to a deficiency in antibody responses to Plasmodium falciparum antigens; however, prior studies have only focused on the antibody response to <0.5% of P.

Association of Abnormal Liver Function Parameters with HIV Serostatus and CD4 Count in Antiretroviral-Naive Rwandan Women.

We determined the associations of HIV infection/CD4 count with markers of hepatocellular damage [elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT)] and liver synthetic function (decreased albumin) in HIV-infected (HIV(+)) antiretroviral therapy (ART)-naive and uninfected (HIV(-)) Rwandan women. In 2005, 710 HIV(+) ART-naive and 226 HIV(-) women enrolled in the Rwanda Women's Interassociation Study and Assessment. Liver enzymes were measured with abnormality defined as either AST or ALT ≥1.

The T-Cell Inhibitory Molecule Butyrophilin-Like 2 Is Up-regulated in Mild Plasmodium falciparum Infection and Is Protective During Experimental Cerebral Malaria.

Plasmodium falciparum infection can result in severe disease that is associated with elevated inflammation and vital organ dysfunction; however, malaria-endemic residents gain protection from lethal outcomes and manifest only mild symptoms during infection. To characterize host responses associated with this more effective antimalarial response, we characterized whole-blood transcriptional profiles in Rwandan adults during a mild malaria episode and compared them with findings from a convalescence sample. We observed transcriptional up-regulation in many pathways, including type I interferon, interferon γ, complement activation, and nitric oxide during malaria infection, which provide benchmarks of mild disease physiology.

Insulin resistance change and antiretroviral therapy exposure in HIV-infected and uninfected Rwandan women: a longitudinal analysis.

Background: We longitudinally assessed predictors of insulin resistance (IR) change among HIV-uninfected and HIV-infected (ART-initiators and ART-non-initiators) Rwandan women.

Methodology: HIV-infected (HIV+) and uninfected (HIV-) women provided demographic and clinical measures: age, body mass index (BMI) in Kg/(height in meters)2, Fat-Mass (FMI) and Fat-Free-Mass (FFMI) index, fasting serum glucose and insulin. Homeostasis Model Assessment (HOMA) was calculated to estimate IR change over time in log10 transformed HOMA measured at study enrollment or prior to ART initiation in 3 groups: HIV- (n = 194), HIV+ ART-non-initiators (n=95) and HIV+ ART-initiators (n=371).

Prevalence of shingles and its association with PTSD among HIV-infected women in Rwanda.

Objective: To examine the prevalence of reported shingles in the last 6 months and its association with post-traumatic stress disorder (PTSD), depression and severity of HIV disease in Rwandan women with HIV.

Settings: This cross-sectional study was conducted as part of the Rwanda Women's Interassociation Study and Assessment (RWISA), an observational cohort study designed to assess the impact of HIV and residual factors from experiencing rape in the 1994 genocide in Rwandan women. Participants were recruited through grassroots women's associations of people living with HIV infection and clinical care sites for HIV infection.

Plasmodium falciparum Infection Does Not Affect Human Immunodeficiency Virus Viral Load in Coinfected Rwandan Adults.

Background: Plasmodium falciparum infection has been reported to increase human immunodeficiency virus (HIV) viral load (VL), which can facilitate HIV transmission. We prospectively studied the impact of mild P falciparum coinfection on HIV VL in Rwanda.

Methods: We measured plasma HIV VL at presentation with malaria infection and weekly for 4 weeks after artemether-lumefantrine treatment in Rwandan adults infected with HIV with P falciparum malaria.

Decentralizing Maternity Services to Increase Skilled Attendance at Birth and Antenatal Care Utilization in Rural Rwanda: A Prospective Cohort Study.

To evaluate the effectiveness of decentralizing ambulatory reproductive and intrapartum services to increase rates of antenatal care (ANC) utilization and skilled attendance at birth (SAB) in Rwanda. A prospective cohort study was implemented with one control and two intervention sites: decentralized ambulatory reproductive healthcare and decentralized intrapartum care. Multivariate logistic regression analysis was performed with primary outcome of lack of SAB and secondary outcome of ≥3 ANC visits.

Trends in and correlates of CD4+ cell count at antiretroviral therapy initiation after changes in national ART guidelines in Rwanda.

Background: Initiation of antiretroviral therapy (ART) in the advanced stages of HIV infection remains a major challenge in sub-Saharan Africa. This study was conducted to better understand barriers and enablers to timely ART initiation in Rwanda where ART coverage is high and national ART eligibility guidelines first expanded in 2007-2008.

Methods: Using data on 6326 patients (≥15 years) at five Rwandan clinics, we assessed trends and correlates of CD4 cell count at ART initiation and the proportion initiating ART with advanced HIV disease (CD4 <200 cells/μl or WHO stage IV).

Sexual Behavior and Risk Practices of HIV Positive and HIV Negative Rwandan Women.

It is not well understood how infection with HIV and prior experience of sexual violence affects sexual behavior in African women. We describe factors influencing current sexual practices of Rwandan women living with or without HIV/AIDS. By design, 75 % of participants were HIV positive and ~50 % reported having experienced genocidal rape.

Building clinical trial priorities at the University of Rwanda.

After the genocide in Rwanda, the country's healthcare system collapsed. Remarkable gains have since been made by the state to provide greater clinical service capacity and expand health policies that are grounded on locally relevant evidence. This commentary explores the challenges faced by Rwanda in building an infrastructure for clinical trials.

Effect of deworming on disease progression markers in HIV-1-infected pregnant women on antiretroviral therapy: a longitudinal observational study from Rwanda.

Background: Deworming human immunodeficiency virus (HIV)-infected individuals on antiretroviral therapy (ART) may be beneficial, particularly during pregnancy. We determined the efficacy of targeted and nontargeted antihelminth therapy and its effects on Plasmodium falciparum infection status, hemoglobin levels, CD4 counts, and viral load in pregnant, HIV-positive women receiving ART.

Methods: Nine hundred eighty HIV-infected pregnant women receiving ART were examined at 2 visits during pregnancy and 2 postpartum visits within 12 weeks.

Association of HIV and ART with cardiometabolic traits in sub-Saharan Africa: a systematic review and meta-analysis.

Background: Sub-Saharan Africa (SSA) has the highest burden of HIV in the world and a rising prevalence of cardiometabolic disease; however, the interrelationship between HIV, antiretroviral therapy (ART) and cardiometabolic traits is not well described in SSA populations.

Methods: We conducted a systematic review and meta-analysis through MEDLINE and EMBASE (up to January 2012), as well as direct author contact. Eligible studies provided summary or individual-level data on one or more of the following traits in HIV+ and HIV-, or ART+ and ART- subgroups in SSA: body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TGs) and fasting blood glucose (FBG) or glycated hemoglobin (HbA1c).

Prevalence and risk factors for High-Risk Human Papillomavirus (hrHPV) infection among HIV-infected and Uninfected Rwandan women: implications for hrHPV-based screening in Rwanda.

Background: New World Health Organization guidelines recommend high-risk human papillomavirus (hrHPV) screen-and-treat strategies for cervical cancer prevention. We describe risk of, and risk factors for, testing hrHPV positive in a pilot study of hrHPV screen-and-treat conducted in Rwanda.

Methods: A total of 2,964 women, 1,289 HIV-infected (HIV [+]) and 1,675 HIV-uninfected (HIV [-]), aged 30-60 years and living in Rwanda were enrolled in 2010.

Associations of HIV infection with insulin and glucose levels in antiretroviral-naive Rwandan women: a cross-sectional analysis.

Objectives: The purpose of these analyses was to determine the associations of HIV infection and related immune dysfunction with a glucose homeostasis in the population of antiretroviral-naïve HIV-infected and uninfected Rwandan women. We hypothesise that insulin resistance and its consequences in the developing countries may be further elevated with HIV infection itself regardless of antiretroviral therapy.

Study Design: Cross-sectional analysis of a longitudinal cohort.

Helminthic infections rates and malaria in HIV-infected pregnant women on anti-retroviral therapy in Rwanda.

Background: Within sub-Saharan Africa, helminth and malaria infections cause considerable morbidity in HIV-positive pregnant women and their offspring. Helminth infections are also associated with a higher risk of mother-to-child HIV transmission. The aim of this study was to determine the prevalence of, and the protective and risk factors for helminth and malaria infections in pregnant HIV-positive Rwandan women receiving anti-retroviral therapy (ART).

The impact of HIV status, HIV disease progression, and post-traumatic stress symptoms on the health-related quality of life of Rwandan women genocide survivors.

Purpose: We examined whether established associations between HIV disease and HIV disease progression on worse health-related quality of life (HQOL) were applicable to women with severe trauma histories, in this case Rwandan women genocide survivors, the majority of whom were HIV-infected. Additionally, this study attempted to clarify whether post-traumatic stress symptoms were uniquely associated with HQOL or confounded with depression.

Methods: The Rwandan Women's Interassociation Study and Assessment was a longitudinal prospective study of HIV-infected and uninfected women.
