Hepatitis C virus (HCV) infection is associated with immune-complex mediatcd disorders, including type II mixed cryoglobulinaemia.
Mixed cryoglobulinaemia is itself low-grade 13-cell lymphoproliferative disorder which may progress to non-Hodgkin's lymphoma (NHL).
Studies from Europe and Asia have found a prevalence of hepatitis C virus infection in non-liodgkin's lymphoma patients as high as 34%. 0ther viral infections are also associated with non-Hodgkin's lymphoma.
We speculated that non-Hodgkin's lymphoma patients in the midwestern USA would have an increased prevalence of hepatitis C infection.
We tested 73 patients with NHL and 20 controls with Hodgkin's disease for anti-HCV antibodies by EIA-2.
Only 1/73 patients and no control subject was positive for anti-HCV.
The anti-HCV positive patient had no identifiable risk factors for hepatitis C, and Al/r was persistently normal.
HCV-RNA testing by RT-PCR was negative.
Thus, none of 73 non-Hodgkin's lymphoma patients could be confirmed to have hepatitis C infection.
In a second part of the study. of 41 patients with HCV infcction followed an average of 28.1 months, only one patient developed non-Hodgkin's lymphoma.
We conclude that in our population, non-Hodgkin's lymphoma is not associated with hepatitis C virus infection.
Based on these results and review of the literature, there are marked regional differences in the prevalence of hepatitis C infection in Non-Hodgkin's lymphoma.
