WebCo-receptor tropism testing is also recommended for patients who exhibit virologic failure on a CCR5 inhibitor (BIII). A phenotypic tropism assay (e.g., Trofile) is preferred to determine HIV-1 co-receptor usage (AI). A genotypic tropism assay should be considered as an alternative test to predict HIV-1 co-receptor usage (BII). WebHIV tropism testing may include phenotype testing or genotyping assays. When to test HIV tropism testing should be performed before Maraviroc therapy is initiated. Maraviroc should only be used in adults with CCR5-tropic HIV-1 infections based on those results.2,4 Testing may also be considered for patients with treatment failure on Maraviroc.

WebRecent findings: Most commercially available HIV-1 tropism assays are cell-based (phenotypic) tests, which use different methodologies to generate env-recombinant viruses and distinct detection systems. On the other hand, a large effort is being devoted to develop more robust bioinformatic (genotypic) tools that may expedite HIV-1 tropism ... WebThis assay has not been validated in a clinical trial setting or against the Trofile assay. Two DNA-based tropism assays are also available.
