Rhinosinusitis in hiv-infected children undergoing antiretroviral therapy

SummaryThe association of protease inhibitors (PI) to antiretroviral therapy has generated sensible changes in morbidity and mortality of HIV-infected patients. Aim: Aims at evaluating the impact of this association on the prevalence of rhinosinusitis (RS) and CD4+ lymphocyte count in HIV-infected children. Methods: Retrospective cross-sectional study of the medical charts of 471 HIV-infected children. In 1996, protease inhibitors were approved for use as an association drug in antiretroviral therapy. Children were divided into two groups: one which did not receive PI and another which received PI after 1996. The prevalence of RS and CD4+ lymphocyte counts were compared between these groups. Results: 14.4% of HIV-infected children had RS. Chronic RS was more prevalent the its acute counterpart. Children under 6 years old who were taking protease inhibitors presented with a significant higher prevalence of acute RS. The association of PI with the antiretroviral regimen was associated to higher mean CD4+ lymphocyte count and lower prevalence of chronic RS. Conclusions: The use of protease inhibitors was associated to higher mean CD4+ lymphocyte count. Children under 6 years of age in antiretroviral therapy associated with PI presented a lower likelihood of developing chronic RS.
