Abstract

Methods Major enrollment criterion was the administration of maraviroc, enfuvirtide, raltegravir, etravirine, darunavir/r or tipranavir/r, alone or in combination, in the latest antiretroviral regimen, decided upon the last genotypic RNA resistance test. This allowed us to assess the genotypic sensitivity score (GSS) at the same time. We also recorded previous presence of specific mutations in all available genotypic resistance tests, their persistence in time and their correlation to the last GSS.

  • R PI: 10FIRVC, 36ILV, 41L, 46IL, 54VLAMTS, 71OVT, 82AFTSLI, 90M and 63P in almost 70–80% of all cases

  • Undetectable viral load was obtained in 64% of patients without difference between genotypic sensitivity score (GSS) classes (HIV-RNA median value
