Abstract
Objective: To evaluate the efficacy and tolerability of clarithromycin plus rifabutin plus clofazimine for the treatment of disseminated Mycobacterium avium complex (MAC) disease in patients with AIDS.
Design: Prospective, open-label, non-randomised study.
Setting: Tertiary care university hospital.
Patients: Thirty consecutive HIV-infected patients with disseminated MAC disease.
Interventions: Patients received the combination of clarithromycin (1000mg twice daily for the first 2 months and 500mg twice daily thereafter), rifabutin (450mg daily), and clofazimine (100mg daily), and were followed up for up to 1 year microbiologically and clinically.
Results: Among the 30 enrolled patients with a median CD4 count of 15/mm3 (range: 0 to 90/mm3) and a positive blood culture for MAC, 23 patients were evaluable for efficacy with a treatment duration of at least 4 weeks. Clinical improvement occurred in 13 (57%) patients within the first month. During the study duration of up to 12 months, 19 (83%) patients achieved a clinical response that was complete in 11 of them. Sterilisation of blood cultures was accomplished in 15 (65%) of the 23 patients. No cases of uveitis occurred during the total treatment duration of 141 patient months. Resistance to clarithromycin developed after a median time of 5.4 months (range: 3.1 to 10.4 months) in six (50%) of 12 patients who had positive blood cultures during treatment.
Conclusions: Although the combination regimen did not prevent development of clarithromycin resistance over long-term observation, our results confirm the activity of a clarithromycin- and rifabutin-containing regimen for the treatment of disseminated MAC disease in AIDS patients.
