muramidase and Angina--Unstable

Coronary heart disease (CHD) is a major killer worldwide. Atherosclerosis, which is the basis of CHD, is believed to be an inflammatory disorder. Though various aspects of atherosclerosis are extensively studied, leukocytic hydrolytic enzymes are not studied very well with respect to CHD.. This study was planned to assess changes associated with leukocytic hydrolases in CHD patients.. A tertiary care hospital; case-control study.. 106 patients with acute myocardial infarction, 60 patients with unstable angina and 45 healthy controls were included in the study. Acid phosphatase, lysozyme, adenosine deaminase (ADA) and cathepsin-G levels were estimated from leukocytes. Reduced glutathione (GSH) and malondialdehyde (MDA) levels were measured.. Statistical comparison of data was done using student's t-test (unpaired). Correlation difference was calculated by using Pearson correlation coefficient.. Significantly higher levels of acid phosphatase, lysozyme, ADA with lower levels of cathepsin G in leukocytes were observed in CHD group. We also found significantly higher levels of serum MDA with lower concentrations of blood GSH in CHD group. In diabetic CHD group, significantly higher levels of leukocytic acid phosphatase, lysozyme, ADA and serum MDA with lower levels of cathepsin G and blood GSH were observed.. Our study indicates that leukocyte hydrolytic enzymes, mainly acid phosphatase, lysozyme and ADA were more active in CHD patients and may contribute to inflammation related with CHD. Its also indicates that leukocyte cathepsin-G may have antiinflammatory role.

Changes of systemic immune status, involved in the immunopathogenesis of atherosclerosis, have been identified in patients with unstable angina pectoris. The developing acute myocardial infarction is accompanied by the formation of a myocardial aseptic inflammatory focus, from which biologically active products are absorbed, resulting in additional immunologic shifts. A differential diagnosis algorithm has been evolved on the basis of the comparison of a series of biochemical and immunologic parameters in patients with unstable angina, investigated at the peak of its clinical manifestations, and those with acute myocardial infarction.

A comparative study of biochemical and immunologic patterns showed lipostabil treatment to be effective in less than half of the patients with unstable angina. A method is developed for in vitro testing of individual blood mononuclear sensitivity to lipostabil effects. The proposed set of biochemical and immune assays allows the selection of patients subject to lipostabil treatment and provides additional criteria for the assessment of its efficiency.
