title: Continuous evidence of fast HIV disease progression related to class-wide resistance to antiretroviral drugs: a 6 year follow-up analysis of a large observational database.
abstract: Class-wide resistance (CWR) was increasingly associated with a higher risk of HIV progression after 72 months of follow-up among 1392 patients genotypic-tested after failure (AIDS risk 13% for no CWR to 34% for three CWR; AIDS/death risk 21-54%). At multivariate analysis, the detection of two and three CWR was significantly associated with a two and threefold increased risk, respectively, of death and AIDS/death, suggesting that extended resistance is a marker of disease progression in long-term observation.
