The Genotyping Resistance Profile of the Pol Gene Detected in Blood of Newly Diagnosed HIV-Positive Men Is Durably Archived in the Gut Whatever the Time of Initiation of cART.

Objective: To evaluate the mutational patterns on the pol gene of the main HIV-1 strain archived in cell genome of 10 chronically infected men according to their clinical and therapeutic history. The genotyping resistance profiles were compared between the first blood plasma available at the time of HIV diagnosis and rectal biopsies and PBMC sampled 1-5 years after the initiation of combined antiretroviral therapy (cART).

Methods: HIV-1 RNA and cell-associated HIV-1 DNA were quantified by Abbott Real-Time HIV-1 and Generic HIV® DNA cell (Biocentric) assays.
