title: Serum concentration of TNF-alpha and IL-1 beta in patients with chronic hepatitis C treated with interferon alpha--a preliminary report.
abstract: The aim of the study was to evaluate the concentration of TNF-alpha and IL-1 beta in 14 chronic hepatitis C patients during interferon treatment in a correlation with biochemical indicators of hepatic cell damage, AspAT and ALAT activity. The study included the sera obtained every month (10-12 measurements) during 48-week therapy. IL-1 beta and TNF-alpha concentrations were determined by ELISA method. Statistic analysis were performed with AnStat program. The wide range of IL-1 beta and TNF-alpha concentration values may prove a differentiated response to immunomodulating treatment with INF-alpha. Concentrations of TNF-alpha, IL-1 beta, show decreasing tendency during therapy. A positive correlation between proinflammatory cytokines (IL-1 beta and TNF-alpha), ALAT and AspAT indicates the role of these cytokines and their relation to a necrotic-inflammatory process demonstrated by aminotransferases concentration.
