dc.description.abstractIntroduction: From 2019, South African antiretroviral therapy (ART) guidelines for first-line therapy in adolescents over 10 years of age, weighing more than 35 kilograms, contains tenofovir (TDF) which has been reported to impact on kidney function. Objectives: We assessed the change in estimated glomerular filtration rate (eGFR) over time in adolescents aged 10-19 years that were ever exposed to TDF at Harriet Shezi Children’s Clinic, Chris Hani Baragwanath Academic Hospital, from 01 January 2010 to 31 December 2015. Results: Of the 346 adolescents receiving TDF-containing ART regimens during the study period, 117 (33.8%) met study inclusion criteria. Twenty (17.1%) developed sustained kidney dysfunction, contributing 246.0 person-years of follow-up; incidence of sustained kidney dysfunction was 8.1 per 100 person-years (95% confidence interval (CI):5.2, 12.6). Those with sustained kidney dysfunction on TDF-containing ART had significantly (P<0.001) lower baseline eGFR compared to adolescents with normal kidney function at last visit (108.56 mL/min/1.73m2 and 133.77 mL/min/1.73m2, respectively). One (0.9%) adolescent required referral to the paediatric nephrology clinic for evaluation of their kidney dysfunction. Conclusions: TDF appears safe in HIV-infected adolescents, however more studies are needed. Closer attention to monitoring of serum creatinine according to guideline recommendations is needed, particularly at TDF initiationand in older adolescents.
