DETECTION OF PLASMA SOLUBLE INTERLEUKIN-2 RECEPTOR IN PATIENTS WITH SEVERE AND CHRONIC ACTIVE HEPATITIS B

Plasma levels of soluble interleukin-2 receptor (sIL-2R) in patients with chronic active hepatitis B (CAHB) or severe hepatitis B (SHB) were measured quantitatively by "sandwich" ELISA with monoclonal antibodies in order to explore the change of sIL-2R levels, its clinical significance,and its relation to liver damage. The results showed that the plasma sIL-2R levels in patients with CAHB and SHB were much higher than those in normal controls (P < 0. 01 ), and the level ofplasma sIL-2R in patients with SHB was greatly higher than that in patients with CAHB. These results suggest that there is close relation between plasma level of sIL-2R, the clinical types of hepatitis B,and the severity of liver damage. In addition, there is no significant difference in plasma levels of sIL-2R between acute severe hepatitis B (ASHB), subacute severe hepatitis B (SASHB), and chronic severe hepatitis B (CSHB). No relation was found between sIL-2R level and hepatitis B virusreplication activity.
