ObjectivesThe aim of the study was to determine whether it is safe to stop secondary prophylaxis in patients with talaromycosis after immune reconstitution with a sustained increase in CD4 count to ≥ 100 cells/µL after antiretroviral therapy (ART).MethodsA retrospective cohort analysis was performed in HIV-infected patients treated for talaromycosis between June 2009 and June 2017 in Medical Action Myanmar (MAM) clinics.ResultsAmong a cohort of 5466 HIV-infected patients, 41 patients were diagnosed with and treated for clinical talaromycosis. All the patients were on ART and had a CD4 count 100 cells/µL for at least 1 year. Throughout the duration of follow-up post itraconazole cessation, the observed incidence of relapse was zero with a total follow-up of 93.8 person-years (95% confidence interval 0-4 per 100 person-years). The median (25th, 75th percentile) duration of follow-up post-prophylaxis discontinuation was 2.8 (2.1, 6.3) years.ConclusionsSecondary prophylaxis can be safely stopped in patients with talaromycosis after immune reconstitution with a sustained increase in CD4 count to ≥ 100 cells/µL after highly active antiretroviral therapy.
