We describe a case of multidrug and class resistant HIV in a patient with psychological issues affecting his adherence. The complexities involved in subsequent treatment decisions when resistance interpretation algorithms are discordant are discussed.

Additional keywords: adherence factors, interpretive algorithms, multi-drug resistance, raltegravir resistance.


We thank the Signe Fransen and scientists at Monogram Biosciences for their help with performing the PhenoSense GT assay and for advice and intellectual input on the assay performance. The method for VIDRL’S in-house integrase genotyping assay is available on request.
