The aim of the present study was to evaluate the role of soluble interleukin 2 receptor (sIL2R) and soluble tumor necrosis factor a receptor (sTNFaR) in patients with chronic hepatitis B in assessment of the severity of the disease. Sixty-three patients with different stages of chronic hepatitis B were investigated. Serum sIL2R and sTNFaR were determined by ELISA and compared with those of 20 healthy normal controls. The levels of sIL-2R and sTNFaR were significantly higher in the diseased group (P< 0.001). In addition, these markers showed linear increase in relation to the severity of the disease, and was more obvious with sTNFaR than IL-2R.. Liver function tests as well as sTNFaR were correlated with liver biopsy by means of discriminant analysis. Soluble TNFaR was found to be a better predictor for the histologic staging of chronic hepatitis B. It is concluded that, sTNFaR together with some liver function tests could be used as a predictor for the histologic progress of chronic hepatitis B.
