Lipoprotein profiles at different stages of chronic renal insufficiency.
BACKGROUND
Lipoprotein abnormalities characteristic of renal dyslipoproteinemia are significantly associated with different stages of chronic renal insufficiency. The renal dyslipoproteinemia may contribute not only to accelerated development of atherosclerosis but also to progression of human chronic renal insufficiency.


METHODS
The purpose of the studies was to estimate the lipid and lipoprotein profiles in 52 not dialysed patients with various renal insufficiency advancement. Basing on creatinine level the patients were divided into 3 groups. CR1-A--serum creatinine 2-5 mg/dL (n = 16), CR1-B--serum creatinine 5-10 mg/dL (n = 19), CR1-C--serum creatinine > 10 mg/dL (n = 17).


RESULTS
In CR1-A and CR1-B dyslipoproteinemia was found at different stages of renal insufficiency which was manifested by the significant increase of TG, TC, LDL-C, apo B levels and TC/HDL-C, LDL-C/HDL-C ratios and significant decrease of HDL-C level and apo AI/apoB, HDL-C/apoAI ratios in comparison with controls. We also observed decreased TG, TC, LDL-C, apo AI, apo B levels and TC/HDL-C, LDL-C/HDL-C ratios and unchanged HDL-C level and apo AI/apoB, HDL-C/apoAI ratios in cm-c in comparison to CR1-A. The decrease of the lipoprotein parameters in CR1-C might result from malnutrition (statistically decreased albumin level) and metabolism disturbances connected with the renal insufficiency advancement. Negative correlation between IG, HDL-C levels (r = -0.43, p < 0.001) and TG, IIDL-C/apoAI (r = -0.56; p < 0.001) were found, which confirmed the abnormal composition of HDL molecules and indicated a high risk of atherosclerosis.


CONCLUSIONS
Our results may indicate that of atherosclerosis in CR1 patients is connected with dyslipoproteinemia and disturbances in HDL molecular composition and with different stages of chronic renal insufficiency.
