Characteristics, management and outcome of patients with recurrent tuberculosis under routine programme conditions in Malawi
Abstract:SETTING: All 43 non-private hospitals in Malawi, which registered TB cases between 1 July 1999 and 30 June 2000.
OBJECTIVES: To determine 1) the characteristics, management and treatment outcome, 2) timing of the previous episode of TB, and 3) pattern of drug resistance in patients registered with recurrent smear-positive pulmonary TB.
DESIGN: Retrospective data collection using TB registers and laboratory culture and drug sensitivity registers.
RESULTS: There were 748 recurrent patients; data were available for 747. Of these, 487 (65%) successfully completed a re-treatment regimen, 185 (25%) died and the remainder had another outcome. Information about previous TB was recorded for 491 (66%) patients. In 286 (58%) there were 2 years or less between completing and re-starting treatment. Only 307 (41%) patients had sputum sent for culture and drug sensitivity tests. In 164 patients with cultures of Mycobacterium tuberculosis, 122 (81%) were fully sensitive, 25 (15%) had resistance to isoniazid and/or streptomycin, and 6 (4%) had resistance to isoniazid and rifampicin (MDR-TB).
CONCLUSION: Patients with recurrent TB had acceptable treatment outcomes, and most had fully sensitive organisms. Over half had recurrent TB 2 years or less after completing treatment. Ways to prevent recurrence need to be investigated and implemented in the field.
