Propósito del estudio

To determine if anti-mycobacterial therapy can be withdrawn from patients who meet the following conditions: prior treatment with macrolide-based therapy over 12 months; asymptomatic for Mycobacterium avium complex (MAC) for at least 16 weeks; CD4+ counts of at least 100 cells/mm3; receipt of antiretroviral therapy for 16 weeks. To estimate the duration of time patients remain free of MAC infection.

Detalles del estudio

A growing body of evidence suggests AIDS-related morbidity and mortality significantly decrease where potent antiretroviral therapies are used. HAART (highly active antiretroviral therapy) seems to significantly reduce the incidence of MAC. This study tests the validity of those observations.Peripheral blood cultures and bone marrow (aspirate) samples from 50 eligible patients previously diagnosed with disseminated Mycobacterium avium complex (DMAC) are assessed for microbiologic sterilization of MAC at the time of study entry. If either bone marrow or blood cultures test positive for MAC, patients are discontinued from study. If cultures prove sterile, patients receive 6 weeks of treatment and then discontinue MAC therapy at Week 6 (entry into Step 2 of study). They are then monitored for clinical signs and symptoms of MAC recurrence and for the presence of mycobacteria in blood cultures. In cases of increased viral load during study, modification of antiretroviral therapy is allowed at the discretion of the patient's provider.

Criterios de exclusión

    Patients will not be eligible for this study if they: Have any active infection (unless they have been on stable chronic suppressive therapy for at least 3 months). Are pregnant.
