Importance: Rheumatic heart disease (RHD) remains a public health issue in low- and middle-income countries (LMICs). However, there are few large studies enrolling individuals from multiple endemic countries.

Objective: To assess the risk and predictors of major patient-important clinical outcomes in patients with clinical RHD.

Article Synopsis
  • Chronic kidney disease (CKD) is a significant health issue in Zambia, with a notable increase in its burden, as measured by disability-adjusted life years (DALYs), from 39.42 million in 1990 to 76.03 million in 2019.
  • Major contributing factors to CKD include hypertension (18.7%), diabetes (22.7%), and glomerulonephritis (33%), primarily affecting adolescents and young adults.
  • The findings stress the urgent need for an effective action plan to raise public awareness and improve prevention and treatment strategies for kidney disease in Zambia.

Background: The genetics of rheumatic heart disease (RHDGen) Network was developed to assist the discovery and validation of genetic variations and biomarkers of risk for rheumatic heart disease (RHD) in continental Africans, as a part of the global fight to control and eradicate rheumatic fever/RHD. Thus, we describe the rationale and design of the RHDGen study, comprising participants from 8 African countries.

Methods: RHDGen screened potential participants using echocardiography, thereafter enrolling RHD cases and ethnically-matched controls for whom case characteristics were documented.

Background: Testing of factor Xa inhibitors for the prevention of cardiovascular events in patients with rheumatic heart disease-associated atrial fibrillation has been limited.

Methods: We enrolled patients with atrial fibrillation and echocardiographically documented rheumatic heart disease who had any of the following: a CHADSVASc score of at least 2 (on a scale from 0 to 9, with higher scores indicating a higher risk of stroke), a mitral-valve area of no more than 2 cm, left atrial spontaneous echo contrast, or left atrial thrombus. Patients were randomly assigned to receive standard doses of rivaroxaban or dose-adjusted vitamin K antagonist.

Background: Rheumatic heart disease (RHD) remains a major source of morbidity and mortality in developing countries. A deeper insight into the pathogenetic mechanisms underlying RHD could provide opportunities for drug repurposing, guide recommendations for secondary penicillin prophylaxis, and/or inform development of near-patient diagnostics.

Methods: We performed quantitative proteomics using Sequential Windowed Acquisition of All Theoretical Fragment Ion Mass Spectrometry (SWATH-MS) to screen protein expression in 215 African patients with severe RHD, and 230 controls.
