Data on hepatitis B (HBV) and c (HCV) viruses interference in hematological patients are described. Patients with a hematological malignancy are at high risk of HBV and HCV infection as recipients of multiple transfusions. Results of the laboratory testing of 339 blood samples of patients treated at the National Research center for Hematology, Russian Federation, were studied. Among these patients, HBV/HCV coinfection markers were observed in 153 patients; HBV markers only, in 76 patients; HCV markers only, in 110 patients. The vast majority of coinfected patients had HBV DNA in blood (significantly more in HBsAg-negative patients: 100% vs. 82.8%, p = 0. 0005). HBsAg-negative coinfected patients had low HBV DNA levels (102-103ME/ml) and reduced (or completely absent) HCV RNA levels. The virus interference leads to a decrease in the viral nucleic acid concentrations. Thus, virus detection should include implementation of high sensitive molecular techniques (such as real-time PCR), and an enhanced set of serological HBV markers along with routine screening methods (HBsAg, anti-HCV).
