Abstract

BackgroundThe Interleukin 28B IL28B rs12979860 polymorphisms was recently reported to be associated with the human T-cell leukemia virus type 1 HTLV-1 proviral load PvL and the development of the HTLV-1-associated myelopathy-tropical spastic paraparesis HAM-TSP.

MethodsIn an attempt to examine this hypothesis, we assessed the association of the rs12979860 genotypes with HTLV-1 PvL levels and clinical status in 112 unrelated Brazilian subjects 81 HTLV-1 asymptomatic carriers, 24 individuals with HAM-TSP and 7 with Adult T cell Leukemia-Lymphoma ATLL.

ResultsAll 112 samples were successfully genotyped and their PvLs compared. Neither the homozygote TT nor the heterozygote CT mutations nor the combination genotypes TT-CT were associated with a greater PvL. We also observed no significant difference in allele distribution between asymptomatic carriers and patients with HTLV-1 associated HAM-TSP.

ConclusionsOur study failed to support the previously reported positive association between the IL28B rs12979860 polymorphisms and an increased risk of developing HAM-TSP in the Brazilian population.
