ABSTRACT
Objective To investigate the corelation between neutropenia (ANC) incidence and infection during treatment with peginterferon alfa and ribavirin for chronic hepatitis C.Methods A retrospective cohort study of 399 patients treated with peginterferon and ribavirin derived from database of Department of Infectious Diseases, the Second Affiliated Hospital, Harbin Medical University was conducted.The incidence of infections and their relation with ANC were investigated.Potential risk factors for infection were identified by multivariate analysis.Results During treatment,neutropenia (ANC < 1.50 ×109/L) occurred in 251 patients.Among which,mild neutropenia [ANC ( > 0.75-< 1.50) x 109/L],moderate neutropenia [ANC ( 0.50-0.75 ) × 109/L]and severe neutropenia ( ANC < 0.50 × 109/L)occurred in 132 patients,103 patients and 16 patients,respectively.A total of 80 infections (20.1% )occurred,among which,14 infections were defined as severe.There was no significant difference in infection rate between patients with and without neutropenia ( 19.9%,50/251 vs 20.3%,50/251 ; x2 =0.007,P =0.933).There was no significant difference in infection rate between patients with and without peginterferon dose reduction ( 21.5%,31/144 vs 19.2%,49/255 ; x2 =0.307,P =0.580 ).In multivariate logistic regression analysis,the independent factors associated with infection were age (P =0.021),diabetes (P =0.004) and cirrhosis (P =0.012).Conclusions Infections during treatment with peginterferon alfa and ribavirin for chronic hepatitis C are irrelevant to neutropenia.The independent factors associated with infection are age,diabetes and cirrhosis.
