[Disturbances of lipid exchange and peroxidation system in patients with chronic pyelonephritis].

The aim of the study was to evaluate the lipid parameters of blood in patients with total or partial clinico-laboratory remission of chronic pyelonephritis (CP), and the role of these parameters in their metabolic status. The subjects were 93 CP patients (mean age 47.4 +/- 0.8 years). The metabolic status of each patient was evaluated according to the activity of the inflammatory reaction, glomerular filtration, and reabsorption, as well as indices of lipid exchange, lipid peroxidation (LPO), and antioxidative protection (AOP). Factor analysis revealed that lipid exchange and LPO-AOP system disturbances played a significant role in the metabolic status of CP patients with total or partial clinico-laboratory remission. There were three variants of these disturbances: an increased serum level of cholesterol (CS) of very low-density lipoproteins (VLDLP), and LPO-AOP disbalance; light hypercholesterinemia, an increased level of VLDLP CS, low-density lipoproteins (LDLP) CS, and a decreased level of LPO-AOP parameters; an increased level of total CS, VLDLP CS, LDLP CS, apoprotein B, and a prominent depression of AOP.
