Usefulness of a genotypic resistance test using dried blood spot specimens in African HIV-infected children with virological failure according to the 2010-revised WHO criteria

Usefulness of a genotypic resistance test using dried blood spot specimens in African... We compared paired plasma and dried blood spot (DBS) samples from 54 HIV-1-treated children living in Bangui, Central African Republic, for antiretroviral-resistance-associated mutations. All children displayed virological failure (HIV-1 RNA >3.70 log 10 copies/ml). Testing for resistance genotype was carried out in a reference laboratory in Paris, France. A successful test result was obtained in 54 (100%) plasmas and 25 DBSs (46%). Among the 732 resistance-associated mutations analyzed, 718 were identical, leading to a high concordance rate of 98.1%. Genotypic resistance tests on DBS samples were found to be highly feasible and accurate in a foreign reference laboratory, but with additional costs for shipping and decreased sensitivity. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
