Acute phase proteins in male Chinese schizophrenic patients in Singapore

Abstract

Changes in the concentration of some serum acute phase proteins ( α 1-antitrypsin, α 2-macroglobulin, complement C 3, haptoglobin, ceruloplasmin, transferrin, albumin and hemopexin), thyroxine-binding globulin, retinol-binding globulin, plasminogen and Gc-globulin are reported in two separate series of Chinese, male schizophrenic patients and healthy controls. In the first series, 41 healthy blood donors and 98 schizophrenic patients in different stages of the disease were investigated. The second series consists of a random sample of 50 acutely ill schizophrenic patients and a second group of healthy subjects. The concentrations of these serum proteins were measured by rocket immunoelectrophoresis in agarose gel. Increased levels of serum α 1-antitrypsin, α 2-macroglobulin, haptoglobin, ceruloplasmin, and thyroxine-binding globulin were observed in both series of patients when compared to their respective controls. Albumin, transferrin and retinol-binding protein levels were reduced in patients in both series. Hemopexin levels were increased only in the acutely ill patients while complement C3 was decreased in the chronically ill patients. No changes were observed in the Gc-globulin levels of all groups of patients. With the exception of complement C3, the changes observed in the levels of these serum proteins were appropriate for that of an acute phase response.
