A Study to Assess Monoclonal B-cell Lymphocytosis in Individuals with Chronic Hepatitis C


About this study

The purpose of this study is to:

  1. To determine the prevalence of MBL in patients with chronic hepatitis C who are to begin therapy with DAA, and compare with clinic controls who are seen in the general medicine clinic at Mayo Clinic

  2. To determine the correlation between the specific subtype of MBL (CD5- MBL, atypical CLL-phenotype MBL and CLL-phenotype MBL) relative to the HCV genotype

  3. To assess the proportion of individuals with MBL who have an improvement in the circulating monoclonal B-cell population following therapy with DAA
