AIM: Although perihepatic lymph node enlargement (PLNE) is reportedly associated with the negative outcome of interferon therapy for chronic hepatitis C, there were limitations in that the results were obtained in patients with various genotypes, viral loads and treatment regimens. We aimed to precisely clarify the significance of PLNE in interferon therapy for chronic hepatitis C.
METHODS: Between December 2004 and June 2005, 112 patients with hepatitis C virus (HCV) genotype 1 and HCV RNA of more than 100 KIU/mL were enrolled, who underwent pegylated interferon-α plus ribavirin therapy thereafter. PLNE was defined as a perihepatic lymph node of more than 1 cm in the longest axis by ultrasonography.
RESULTS: The sustained virological response (SVR) rate was lower in patients with PLNE (4/22, 18.2%) than in those without (37/90, 41.1%; P = 0.045) and viral load decline was smaller in patients with PLNE than in those without (P = 0.028). The proportion of PLNE positive patients was the smallest in the SVR group (P = 0.033) among the patient groups divided by the treatment outcome. PLNE was retained as a negative predictor for SVR by multivariate logistic regression analysis (P = 0.012). Furthermore, PLNE was not significantly associated with the mutations at HCV core protein and at interferon sensitivity-determining region, or interleukin-28B polymorphism in 45 patients with HCV genotype 1, enrolled between December 2011 and March 2012.
CONCLUSION: PLNE is a negative predictor for SVR in patients with HCV genotype 1 and HCV RNA of more than 100 KIU/mL treated with pegylated interferon-α plus ribavirin, independent of other known predictors for SVR.
