Bacterial infection and neutropenia during peginterferon plus ribavirin combination therapy in patients with chronic hepatitis C with and without baseline neutropenia in clinical practice

Summary Background Peginterferon-α–based therapy frequently leads to neutropenia. It remains unclear whether neutropenia is associated with bacterial infection in chronic hepatitis C (CHC). Aim To evaluate the risk of bacterial infection and neutropenia in patients with CHC treated with peginterferon-α/ribavirin. Methods In all, 207 patients with CHC with (group A, n = 30) and without (group B, n = 177) baseline neutropenia were treated with peginterferon-α/ribavirin. Results Group A had significantly higher rates of moderate (
