Prevalence of Hepatitis C Virus Infection in Patients with Lymphoproliferative Disorders

    Summary

    Background: Epidemiological studies in different parts of the world have revealed controversial results on the association between hepatitis C virus infection and non-Hodgkin’s lymphoma. This discrepancy suggests that HCV[1] lymphotropism or its effect on host lymphocytes may be influenced by regional and racial factors, as well as by genomic variations.

    Objective: To determine the prevalence of HCV infection in patients with lymphoproliferative disorders diagnosed and treated in our institute in Israel.

    Methods: A total of 212 consecutive patients (95 males and 117 females) treated in our hematology outpatient clinic between August 1997 and September 1999 was screened for anti-HCV antibodies and hepatitis B surface antigen. HCV infection was confirmed by the presence of HCV RNA in the serum. The prevalence of HCV in patients with lymphoproliferative disorders was compared to a control group of patients with myeloproliferative disorders and myelodysplastic syndromes.

    Results: HCV infection was more prevalent in the group of LPD[2] patients than in the control group, but this finding was not statistically significant. The prevalence of HCV among LPD patients was 7.8%, while that in the group with myeloproliferative and myelodysplastic disorders was 1.19% and in the general population 0.64%. Among the different classes of LPD, a significant association with HCV infection was established only in patients with diffuse large B cell lymphoma. Furthermore, HCV infection was significantly more prevalent than HBV infection in the LPD group, but not in the myeloproliferative and myelodysplastic disorders group.

    Conclusions: Our finding of a significant association between HCV infection and diffuse large B cell lymphoma leads us to suggest that anti-HCV antibodies be performed routinely in such subjects.
