Human Immunodeficiency Virus–Infected Persons with Mutations Conferring Resistance to Zidovudine Show Reduced Virologic Responses to Hydroxyurea and Stavudine‐Lamivudine

Abstract
The baseline predictors of poor virologic response (P = .02) for use of lower dose hydroxyurea (500 mg/day) and 14.7 (95% CI, 1.1–200; P = .04) for the presence of a zidovudine-related mutation. For the stavudine-lamivudine study, the OR of failure to achieve a virologie response at 4 weeks in a multivariate logistic regression model was 23 (95% CI, 2.7–199; P = .004) for the presence of a mutation at codon 215.
