Abstract

INTRODUCTION: Multidrug-resistant tuberculosis (MDR-TB) is a significant public health challenge in Rwanda.

METHODS: This retrospective study aimed to describe the epidemiological characteristics, diagnostic approaches, and treatment outcomes of MDR-TB cases between July 1, 2019 and June 30, 2023.

RESULTS: Among 23,476 tuberculosis cases diagnosed in Rwanda, 227 (0.96&#xa0;%) were confirmed as MDR-TB. Key findings include male predominance (80.6&#xa0;%) and a mean age of 39.6&#xa0;years. Pulmonary tuberculosis accounted for 96.9&#xa0;% of cases, and 20.3&#xa0;% of patients were co-infected with HIV. The GeneXpert molecular diagnostic test - the first-line diagnostic tool - demonstrated a sensitivity of 92.9&#xa0;% for detecting resistance to rifampicin and isoniazid. The overall therapeutic success rate was 93.5&#xa0;%, with a mortality rate of 5.3&#xa0;% in evaluable cases (82.4&#xa0;%). Risk factors for mortality included HIV co-infection and malnutrition (BMI < 18.5&#xa0;kg/m).

CONCLUSION: These findings underscore the importance of robust diagnostic and treatment strategies to control MDR-TB in Rwanda.
