Objective: To evaluate the performance of interferon gamma release assays and tuberculin skin test in HIV-infected children and adolescents with immune reconstitution. Methods: A cross-sectional study was conducted in HIV-infected patients aged 5-18 years receiving antiretroviral treatment with CD4 T-lymphocytes >25% or >500 cells/mm3 for at least 6 months. QuantiFERON-TB Gold, T-SPOT.TB, and tuberculin skin test were performed in each patient. Results: A total of 50 patients were enrolled with median age of 13.7 years, CD4 counts of 753 (IQR: 587-989) cells/mm3. Among 27 patients with tuberculosis (16) or tuberculosis exposure (11), 8 (29.6%) were positive to at least one test, 2 (7.4%) were positive QuantiFERON-TB Gold, 3 (11.1%) positive T-SPOT.TB, and 7 (25.9%) had tuberculin skin test ≥5 mm. Among 23 patients without history of tuberculosis or exposure, all had negative interferon gamma release assays, while 2 (8.7%) had positive tuberculin skin test. Conclusions: All tests had low sensitivity despite immune reconstitution.
