ABSTRACT
Objective:
To investigate if there is a difference in response to tuberculosis treatment between HIV-Seropositive and HIV-seronegative patients in South-Eastern Uganda.Design:
Prospective cohort study.Setting:
St. Francis Leprosy Centre; south-East Uganda.Subjects:
four hundred fifty seven patients with never previously treated sputum smear-positive tuberculosis admitted during a two-year period in 1991/1993. Intervention Intensive phase treatment with streptomycin; isoniazid; rifampicin and pyrazinamide. Main outcomemeasures:
Sputum conversion from a positive to a negative smear at eight weeks of treatment.Results:
HIV seropositivity prevalence was 28among HIV seronegative patients; conversion to a negative smear status occurred in 76 persons compared to 78 in HIV seropositive patients.This difference was not statistically significant (OR=0.9; 95CI; 0.6-1.5). HIV seropositive patients; however; were more likely to die (p=0.017). A high prevalence or resistance to isoniazid and streptomycin was found. Isoniazid restance was more likely in HIV seronegative patients with M.tuberculois strains compared to HIV seropositive persons (p0.005). Initial resistance to antituberculosis drugs did not have a significant effect on smear conversion.Conclusion:
This study demonstrates that HIV-seropositive status is not a principal factor in delaying sputum conversion among patients receiving intensive phase tuberculosis treatment
