Abstract. In recent years, increasing attention has been paid to the index non-high-density lipoprotein cholesterol (non-HDL-cholesterol), an elevated level of which is considered as a factor for the progression of atherosclerotic cardiovascular and renal diseases.
The aim: to assess the incidence and clinical and functional manifestations of elevated non-HDL-cholesterol in patients with chronic kidney disease (CKD).
Material and methods. This retrospective analysis included data from 553 patients with CKD aged 18–70 years (mean age 37.7 ± 12.4 years). All subjects underwent clinical laboratory testing, including a blood lipid profile. Non-HDL-cholesterol level was defined as the difference between total cholesterol and high-density lipoprotein cholesterol; non-HDL-cholesterol was considered as elevated if its level was ≥ 3.7 mmol/L.
Results. Elevated non-HDL-cholesterol was detected in 57.3% of patients with CKD (56.3% in male and 59.2% in female individuals). The average non-HDL-cholesterol level was 4.76 mmol/L (4.84 mmol/L in males and 4.59 mmol/L in females). The highest frequency of this index increase was fixed at CKD stages C3B (70.0%), C2 (68.1%), C3A (65.5%) and C1 (58.5%). In males, its high values were more often recorded at stages C1 (16.8%), C2 (13.2%) and C5 (10.2%), and in females – at stages C2 (14.1%), C5 (11.4%) and C1 (10.8%). Median non-HDL-cholesterol values were statistically significantly higher in the early stages of CKD. Reliable correlations were established between the level of non-HDL-cholesterol and systolic blood pressure (r = -0.099), hemoglobin content (r = 0.266), platelet number (r = 0.235), erythrocyte sedimentation rate (r = 0.370), fibrinogen levels (r = 0.613), total protein (r = -0.575), albumin (r = -0.558), creatinine (r = –0.216), estimated glomerular filtration rate (r = 0.236) and daily proteinuria (r = 0.501).
Conclusion. Patients with CKD often have elevated levels of non-HDL-cholesterol, which likely reflects the activity of the pathological process in renal tissue. The identified associations between non-HDL-cholesterol levels and clinical and laboratory parameters confirm the advisability of their assessment as part of routine follow-up to slow the progression of renal failure and reduce the risk of cardiovascular complications.
