Renal safety of tenofovir in HIV-infected children: a prospective, 96-week longitudinal study.

Background: The renal safety of tenofovir in HIV-infected children has not been well studied. In paediatrics, prediction of glomerular filtration rate (GFR) is usually obtained by the Schwartz equation; the Cockcroft-Gault equation is considered more appropriate in children aged >12 years, but can be misleading in younger children. The aims of this study were to assess renal safety and GFR changes as estimated by the Schwartz and Cockcroft-Gault equations in HIV-infected children treated with tenofovir for 96 weeks.
