IMPACT OF TUBERCULOSIS AND ANTITUBERCULOUS CHEMOTHERAPY ON LIPID COMPOSITION OF THE BLOOD PLASMA

Abstract

Tuberculosis is an infectious disease caused by tuberculosis mycobacteria of human or bovine types and is characterized by multiple organs failure and chronic recurrent course. The blood plasma lipid spectrum state is one of the antituberculous chemotherapy toxic effect markers. The important role of the ratio of various fractions of general and blood phospholipids for the evaluation of the state of the organism in infectious pathology is proved. The purpose of this work is to study the features of the lipid spectrum of blood plasma in patients with pulmonary tuberculosis prior to treatment and at the end of the intensive phase of antituberculous chemotherapy. Three hundred and eight young and middle-aged patients with pulmonary tuberculosis were examined. The lipid and phospholipid spectrum of blood was determined prior to initiating the antituberculous chemotherapy and after the end of the intensive phase. The absolute content of general lipids and total phospholipids of blood plasma, as well as all their fractions, in patients with pulmonary tuberculosis were higher than in healthy volunteers. In this regard, the representation of the lipid spectrum in absolute units does not reflect all the features of lipid metabolism disruption, which is primarily manifested in the plasma lipids main classes ratio violation. It is shown that the spectrum of lipid and phospholipid composition of blood plasma in patients with pulmonary tuberculosis differs significantly from the spectrum in healthy people. Antituberculous chemotherapy with bactericidal and bacteriostatic action comes with normalization of a number of lipid metabolism indicators such as free fatty acids, triglycerides, cholesterol esters and phosphatidylserine. However, such indicators as total phospholipids, free cholesterol and lysophospholipids show negative dynamics, which is probably caused by the antituberculous drug’s effect.
