[Genotype of hepatitis C virus in hemophiliacs]

Testing of blood sera of 63 hemophiliacs revealed markers of hepatitides B and C in 97 and 98% cases, respectively. Polymerase chain reaction confirmed the presence of hepatitis C virus (HCV) RNA in 31 (94%) out of 33 sera tested which contained antibodies to HCV. Gene typing of the isolated strains revealed the presence of three types of HCV: 1b (94%), 2a (3%), and 3a (3%). Similar distribution of HCV genotypes was revealed in the blood sera of 39 patients with chronic hepatitis C.
