A poster just presented at CROI 2022 from the CHARTER study reported that TAF was associated with telomere shortening, but not tenofovir disoproxil. [1]This was in 121 HIV positive people initialling assessed from 2003–7 and again a median of 12 years later, but this had the significant limitation that baseline samples were not available on TAF because it was not yet available.Last month a prospective 17-year study from the Swiss HIV Cohort reported that untreated HIV was associated with significant reductions in telomere length (TL) but that effective ART stopped further damage. This study did not find any association with individual HIV drugs. [2, 3]By Simon Collins, HIV i-Base
