Article Synopsis
  • Rwanda's Hepatitis C elimination campaign focused on mass screenings, but considering a "micro-elimination" strategy targeting specific groups, like non-communicable disease (NCD) patients, might be more effective.
  • A study involving over 7,600 NCD patients revealed a 6.7% prevalence rate for Hepatitis C antibodies and 2.0% for Hepatitis B, with higher rates among older individuals, particularly those over 70 years.
  • While many patients screened positive, only a small percentage were successfully linked to care, highlighting the need for improved identification and management strategies for those co-infected with Hepatitis C and NCDs.

Introduction: To combat poor clinical outcomes among HIV-positive youth, Partners In Health/Inshuti Mu Buzima (PIH/IMB) implemented Adolescent Support Groups (ASGs), which combined peer support and group-based economic incentives to promote treatment adherence, economic empowerment, and viral suppression. This study assesses the association between ASG membership and clinical outcomes among HIV-positive youth living in rural Rwanda.

Methods: We constructed a retrospective cohort using PIH/IMB's electronic medical record (EMR) system.

Introduction: In sub-Saharan Africa, youth living with HIV, especially those who have lost one or both parents, face economic, socially and psychological challenges that hinder adherence to ART, ultimately leading to poor health outcomes. Partners In Health/Inshuti Mu Buzima implemented an Adolescent Support Group (ASG) to support HIV-positive youth aged 15-25 years. During the evaluation of the ASG program, we sought to better understand youths' lived experiences to improve our delivery of HIV care.

Background: In 2016 Rwanda adopted "treat all" where all patients with HIV are immediately eligible for ART regardless of disease progression. Despite widespread availability of treatment, it is unknown whether presentation with advanced HIV persists.

Methods: We conducted a retrospective cohort among patients aged ≥ 15 who enrolled in care between July 2016 and July 2018 in three rural Rwandan districts.

Background: Malaria is a potentially fatal disease spread by the bites of Plasmodium-infected Anopheles mosquitoes. Despite long-term efforts to control malaria in Rwanda, malaria incidence increased from 48 to 403 cases/1000 individuals between 2012 and 2016. The diagnosis and treatment of malaria occurs at multiple levels, but the costs of these activities are not well understood.

Introduction: The World Health Organization has called for the elimination of hepatitis B virus (HBV) and hepatitis C virus (HCV) as public health threats by 2030. In response to the United Nations High Commissioner for Refugees requests, Rwanda became the first country to include refugees in its national viral hepatitis prevention and management program in 2019. We used secondary data to describe the implementation of the first HBV and HCV screening program among refugees in Rwanda.

Article Synopsis
  • - The study evaluated the progression of individuals who tested positive for hepatitis C virus (HCV) during a mass screening in rural Rwanda, focusing on how well they moved through the healthcare system from diagnosis to treatment success.
  • - Among 666 HCV positive participants, the majority were female (68.1%) with a median age of 61; while most received viral load results, only a little over half achieved sustained virological response (SVR12), which indicates successful treatment.
  • - Timely care was a significant issue, with only 66% receiving their initial viral load results within 30 days and a median total time of 437 days from screening to SVR12 assessment, suggesting delays in the treatment process in these low

Youth living with HIV in rural Rwanda experience poor clinical outcomes. In 2017, we implemented Adolescent Support Groups (ASGs), which provided economic incentives and peer support to youth aged 15-25. We assessed the ASG program using programmatic and electronic medical records.

Article Synopsis
  • A mass screening campaign for hepatitis B and C was conducted among Burundian refugees in Rwanda to understand the viral hepatitis epidemiology in the region.
  • The study involved screening 26,498 refugees, finding a seroprevalence of 3.8% for hepatitis B and 1.1% for hepatitis C, with certain age and sex trends noted.
  • Key risk factors for hepatitis B and C included household contact history, diabetes, family history, heart disease, and previous surgeries, revealing similarities in prevalence compared to the broader Rwandan population.

Article Synopsis
  • Curative direct-acting antiviral treatment (DAA) can help eliminate hepatitis C, but a lack of patient knowledge poses a challenge for effective screening and treatment.
  • *In a study of 333 rural Rwandan patients starting DAA, pre-treatment knowledge showed that many were unaware of critical information about hepatitis C, such as its curability and potential health risks.
  • *Post-treatment, while knowledge improved significantly, misconceptions about transmission routes remained common, highlighting the need for targeted public education efforts.*

Background: To eliminate hepatitis C, Rwanda is conducting national mass screenings and providing to people with chronic hepatitis C free access to Direct Acting Antivirals (DAAs). Until 2020, prescribers trained and authorized to initiate DAA treatment were based at district hospitals, and access to DAAs remains expensive and geographically difficult for rural patients. We implemented a mobile clinic to provide DAA treatment initiation at primary-level health facilities among people with chronic hepatitis C identified through mass screening campaigns in rural Kirehe and Kayonza districts.

Tenofovir disoproxil fumarate (TDF) genotypic resistance defined by K65R/N and/or K70E/Q/G occurs in 20% to 60% of individuals with virological failure (VF) on a WHO-recommended TDF-containing first-line regimen. However, the full spectrum of reverse transcriptase (RT) mutations selected in individuals with VF on such a regimen is not known. To identify TDF regimen-associated mutations (TRAMs), we compared the proportion of each RT mutation in 2873 individuals with VF on a WHO-recommended first-line TDF-containing regimen to its proportion in a cohort of 50,803 antiretroviral-naïve individuals.

Objective: To evaluate HIV drug resistance (HIVDR) and determinants of virological failure in a large cohort of patients receiving first-line tenofovir-based antiretroviral therapy (ART) regimens.

Methods: A nationwide retrospective cohort from 42 health facilities was assessed for virological failure and development of HIVDR mutations. Data were collected at ART initiation and at 12 months of ART on patients with available HIV-1 viral load (VL) and ART adherence measurements.

Background: Studies of patients failing second-line antiretroviral therapy (ART) in resource-limited settings (RLS) are few. Evidence suggests most patients who appear to be virologically failing do so not due to drug resistance but to poor adherence, which, if properly addressed, could allow continued use of less expensive first- and second-line regimens. Drug resistant mutations (DRMs) were characterized among patients virologically failing second-line ART in Rwanda.

Article Synopsis
  • A study in Kigali, Rwanda, assessed the prevalence of transmitted drug resistance (TDR) among young adults newly diagnosed with HIV due to concerns about increasing drug resistance from wider ART use.
  • The research, conducted between May and July 2011, involved genotyping blood samples from 68 participants, predominantly female, aged 15 to 21 years.
  • Results showed a low TDR prevalence of 3.5% for non-nucleoside reverse transcriptase inhibitors (NNRTI) and 1.8% for protease inhibitors (PI), indicating that current ART regimens remain effective but highlight the need for ongoing surveillance as ART scaling continues.

Article Synopsis
  • Delayed initiation of antiretroviral therapy (ART) for HIV patients is a significant issue in resource-limited countries, prompting a study analyzing data from 31,033 patients in Rwanda from 2005-2010.
  • The study found that 32.7% were eligible for ART at enrollment, with higher rates of ART initiation (77.2%) within three months for those eligible at that time compared to those who became eligible later (67.9% for initially ineligible and 63.8% for indeterminate).
  • Improved program quality from 2006 to 2011 contributed to faster ART initiation, highlighting the importance of early eligibility assessment and prompt treatment access.
