HLA class II DRB1 polymorphism in Argentinians undergoing chronic Trypanosoma cruzi infection.

DNA typing of human lymphocyte antigen (HLA)-dicloro-1-[beta]-D-ribofuranosyl-benzimidazole 1 (DRB1) alleles in 35 individuals serologically positive for T. cruzi and in 41 healthy controls was performed. DRB1*0409 allele was significantly more prevalent in seropositive individuals, with a trend being also observed for the DRB1*0701 and DRB1*1503 alleles. Although statistically insignificant, the latter was found more frequent in cases with cardiomyopathy.

[Alloimmunization to a high frequency Rh antigen].

We report the case of a pregnant woman sensitized with a panreactive anti-Rh17 alloantibody. Patient's red blood cells showed a partial deletion of Rh antigens, which was responsible for the alloimmunization. An autotransfusion program was instrumented so as to cover possible demands. Molecular analysis of the RH locus showed the presence of a hybrid RHCE-D(5-7)-CE allele that gave origin to the deleted phenotype.
