摘要: We evaluated zidovudine-experienced patients for whom treatment with indinavir, lamivudine, and zidovudine failed, indinavir-resistant minority variants. Of 10 plasma human immunodeficiency virus type 1 RNA suppression subsequent rebound, 6 without primary indinavir-resistance mutations underwent clonal analysis. One had evidence of V82A in 9 30 clones at week 24, no increase 40. The dominant week-40 82V-M184V changes protease codons 62-64, compared all 24 Resistance to indinavir can emerge during failure nucleoside-experienced but may be missed by routine sequence Selection variants on occur slowly, depending the genetic context which they arise.
