Primary drug-resistance in HIV-positive patients on initiation of first-line antiretroviral therapy in Germany.

Abstract

The prevalence of primary resistant virus strains can be estimated at 14% in chronically infected HAART-naive HIV-patients in Germany. The majority of these cases show NRTI-associated resistance. Resistance against NNRTI or PI as well as multi-class-resistance is of low prevalence. No risk factor of predictive value can be identified for the diagnosis of resistance mutations in the individual. In conclusion, routine genotypic resistance testing in untreated HIV-positive patients should be performed before administration of first-line HAART in this region.
