Serum level of soluble intercellular adhesion molecule-1(sICAM-1) and soluble vascular cell adhesion molecular-1(sVCAM-1) and its clinical significance in patients with viral hepatitis B / 中国免疫学杂志

ABSTRACT

Objective:To further explore the relationship between Type Ⅰ hypersensitivity reaction and the mechanism of the viral hepatitis B through the research of soluble intercellular adhesion molecular-1(sICAM-1) and soluble vascular cell adhesion molecular-1(sVCAM-1) levels in serum in patients with viral hepatitis B related to Type Ⅰ hypersensitivity reaction and the damage of liver cells, and therefore, provide new theory for the perfection of the immunological mechanism of hepatitis B, especially acute hepatitis B.Methods:Serum sICAM-1 and sVCAM-1 levels were measured in 45 patients with viral hepatitis B and 15 normal cases using double antibody sandwich ELISA method. ALT and AST levels were studied using omni automatic biochemistry analyzer and its correlation with sICAM-1 and sVCAM-1 were observed.Results:The sICAM-1 and sVCAM-1 levels of 7 acute hepatitis B were significantly higher than that of the normal cases. ②The sICAM-1 and sVCAM-1 levels of 38 chronic hepatitis B were also significantly higher than that of the normal cases. ③The sICAM-1 and sVCAM-1 levels of 13 cases moderate chronic hepatitis B were significantly higher than that of 16 cases mild chronic hepatitis B. ④The sICAM-1 and sVCAM-1 levels of 9 serious chronic hepatitis B were significantly higher than that of the group of mild chronic hepatitis B. ⑤Levels of sICAM-1 were significantly positively correlated with serum ALT and AST. ⑥sVACM-1 levels were significantly positively correlated with serum ALT and AST. In conclusion, sICAM-1 and sVCAM-1 levels in patients with acute hepatitis B were most remarkably increased, and then serious chronic hepatitis B, moderate chronic hepatitis B, light chronic hepatitis B in sequence.Conclusion:Serum sICAM-1 and sVCAM-1 levels in patients with viral hepatitis B may reflect the damage of liver. ②Examination of serum sICAM-1 and sVCAM-1 levels in patients with hepatitis B can be used to judge the patient’s condition and to diagnose. ③As an important indication of the inflammatory in Type Ⅰ hypersensitivity reaction, sICAM-1 and sVCAM-1 may interfere the appearence of hepatitis B and the procedure of immunological damage of liver cells.
