Improved thymic function has been suggested as the main factor associated with CD4+ T cell restoration after HAART. This work was undertaken to determine, among host factors, the predictor variable at baseline involved in the magnitude of short- and long-term recovery of CD4+ T cells after HAART. HIV-RNA levels and CD4+ T cell numbers were determined in 54 HIV-infected adults at baseline and at weeks 4, 12, 48 and 96 after HAART. T cell subpopulations were determined by flow cytometry, thymic volume by computed tomography, T cell receptor excision circle (TREC)-bearing cells by quantitative polymerase chian reaction (PCR) and interleukin (IL)-7 levels by enzyme linked immunosorbent assay at baseline. The phenotype of patients\u2019 isolates was determined by infecting GHOST cells expressing CCR5 and CXCR4. The possible interference of phenotype with thymic function was also analysed. Baseline thymic volume was associated independently with the magnitude of short- and long-term recovery of CD4+ T cells after HAART, despite the patients\u2019 viral phenotype. The measurement of thymic volume before therapy may predict the magnitude of T cell increase. This result could have important clinical implications not only in HIV-infected patients, but also in other scenarios of T cell depletion such as bone marrow transplantation and chemotherapy.<\/jats:p>","DOI":"10.1111\/j.1365-2249.2004.02474.x","type":"journal-article","created":{"date-parts":[[2004,5,14]],"date-time":"2004-05-14T14:46:12Z","timestamp":1084545972000},"page":"501-506","source":"Crossref","is-referenced-by-count":37,"title":["Thymic
