[Increased levels of beta 2-microglobulin in peripheral blood mononuclear cells and hepatocytes in patients with chronic hepatitis type B].
The levels of beta 2-microglobulin (beta 2m) in peripheral blood mononuclear cells (PBMC) and livers from patients with chronic liver diseases type B were measured. Beta 2m of liver and PBMC in chronic active hepatitis was higher than those of controls (p less than 0.01, p less than 0.01). beta 2m of PBMC are directly proportional to those of livers (r = 0.746), beta 2m levels of PBMC in patients with chronic active hepatitis during the exacerbation of hepatitis was higher than those of remission of hepatitis. The levels of beta 2m in PBMC in vivo, was significantly increased during either interferon alpha or beta administration. Interferon-gamma positive cells in the liver were exacted in the beta 2m increased group of chronic hepatitis type B. INF-gamma production in the lymphocyte of livers, may play an important role in the occurrence of liver injury in patients with chronic hepatitis type B.
