Chronic kidney disease (CKD) is associated with a higher risk of new-onset dyslipidemia, including high triglycerides, low high-density lipoprotein cholesterol, and high triglycerides/high-density lipoprotein cholesterol ratios, in the general population. These specific lipid abnormalities in CKD patients may contribute to the increased risk of cardiovascular disease.
Background and aims: Dyslipidemias are common among patients with chronic kidney disease (CKD) and are a major risk factor for cardiovascular disease. This study aimed to investigate the association between early-stage CKD and new-onset dyslipidemia for each lipid profile. Methods: This nationwide longitudinal study included data from the Japan Specific Health Checkups (J-SHC) Study. New-onset dyslipidemia was indicated by hypertriglyceridemia (High-TG; >150 mg/dL), hyper-LDL cholesterolemia (High-LDL-C; >140 mg/dL), or hypo-HDL chelesterolemia (Low-HDL-C; <40 mg/dL) levels according to the guideline of Japan Atherosclerosis Society, or High-TG/HDL-C ratio (>3.5) which was a good predictor of atherosclerosis. The incidence of new-onset dyslipidemia was compared between participants with and without CKD. Survival curves were used to analyze the incidence of each dyslipidemia. Results: Of 289,462 participants with a median follow-up period of 3 years, the incidence of High-TG, High-LDLC, Low-HDL-C, and High-TG/HDL-C ratios were 64.4/1000 person-years, 83.1/1000 person-years, 14.5/1000 person-years, and 39.6/1000 person-years, respectively. The adjusted hazard ratios (95% confidence intervals) for High-TG, High-LDL-C, Low-HDL-C, and High-TG/HDL-C ratio were 1.09 (1.05-1.13), 0.99 (0.95-1.04), 1.12 (1.05-1.18), and 1.14 (1.09-1.18), respectively, in CKD participants as compared to non-CKD participants. Decreased eGFR and presence of proteinuria were independently associated with higher risks for new-onset of High-TG, Low-HDL-C, and High-TG/HDL-C ratios. Conclusions: CKD was associated with a higher risk of new-onset High-TG, Low-HDL-C, and High-TG/HDL-C ratios, but not High-LDL-C, in the general population. These CKD-specific lipid abnormalities may explain the residual risk for CKD-related cardiovascular disease.
