Efficacy and safety of anti-tuberculosis drugs in HIV-positive patients: a prospective study

To assess the efficacy and safety of anti-tuberculosis drugs in HIV-positive patients at a tertiary care teaching hospital.

As a part of an ongoing study of opportunistic infections (OIs) in HIV-positive patients, drug treatment in patients suffering from tuberculosis was assessed to determine its efficacy and safety. Based on prevalence data for last three years, a purposive sampling of study population was carried out in this observational, prospective, single centre study. Tuberculosis (TB) was the most common OI observed. The selected patients were followed up for a period of one year to evaluate the clinical course and outcome of OIs, and the efficacy and safety of drugs used was checked.

Tuberculosis was observed in 89 out of 134 enrolled patients. These included 79 adults and 10 children. Males (66.2%) were commonly affected. Extra pulmonary TB (73%) was the most common manifestation with abdominal TB observed in 55 (61.7%) patients. All patients were treated in accordance with the Revised National Tuberculosis Control Programme (RNTCP) guidelines as recommended by National AIDS Control Organization (NACO), India. Outcome of TB was assessable in 70 patients. Majority (82.8%) of the patients were cured, while 12 patients (17.1%) died during the course of treatment. A total of 149 ADRs were observed in 67 (75.2%) patients. Majority of ADRs (n = 147) were non-serious and did not warrant a change in therapy. Discoloration of urine was the most common ADR observed.

TB is the most common opportunistic infection in HIV-positive patients with abdominal TB being the most common manifestation. RNTCP and NACO guidelines are adhered to in these patients. Anti-tuberculosis drugs are well tolerated and effective in majority of the patients.
