Drug-Resistant tuberculosis in Ethiopia: Characteristics of cases in a referral hospital and the implications

Background: Tuberculosis (TB) programs should design intervention strategies based on the sound knowledge of the existing local epidemiology and sociodemographic characteristics of drug-resistant-TB (DR-TB) cases. The aim of the study was to characterize the pulmonary multidrug-resistant (MDR) and rifampicin-resistant (RR) TB cases enrolled in a referral hospital at Addis Ababa, Ethiopia, called All Africa Leprosy, Tuberculosis, Rehabilitation and Training (ALERT) Hospital. Methods: We conducted a descriptive study based on retrospective review of medical records of 340 pulmonary MDR/RR-TB cases enrolled in ALERT Hospital from November 2011 to December 2016. To characterize the cases, we described the distribution of demographic and clinical characteristics. To compare the distribution of demographic and clinical characteristics between male and female cases, we used Pearson's Chi-squared test. Results: Males accounted for 52.9% of the 340 cases. Nine out of ten cases were in the age group of 15–44 years. Sputum acid-fast bacilli smear-positive and human immunodeficiency virus-coinfected cases constituted 63.7% and 18.1% of cases, respectively. The proportion of new cases increased through the years from nil in 2011 to 21.4% in 2016. Adult males above 24 years constituted more than three quarters (77.2%) of the total male cases, while adult females in this age group constituted 56.9%. The age distribution between male and female cases showed significant differences ( P Conclusion: There is age disparity between male and female cases with high impact of MDR/RR-TB on productive adult male population. The transmission potential for DR-TB is also high in the community.
