Abstract

Abstract: Background: High serum uric acid (SUA) is associated with the dyslipidemia, but whether hyperuricemia predicts an increase in serum low-density lipoprotein (LDL) cholesterol is unknown. This study is to evaluate whether an elevated SUA predicts the development of high LDL cholesterol as well as hypertriglyceridemia. Methods: This is a retrospective 5-year cohort study of 6476 healthy Japanese adults (age, 45.7 ± 10.1 years; 2.243 men) who underwent health examinations at 2004 and were reevaluated in 2009 at St. Luke's International Hospital, Tokyo, Japan. Subjects were included if at their baseline examination they did not have hypertension, diabetes mellitus, dyslipidemia, chronic kidney disease, or if they were on medication for hyperuricemia and/or gout. The analysis was adjusted for age, body mass index (BMI), smoking and drinking habits, baseline estimated glomerular filtration rate (eGFR), baseline SUA and SUA change over the 5 years. Results: High baseline SUA was an independent risk for developing high LDL cholesterol both in men (OR: 1.159 per 1 mg/dL increase, 95% CI:1.009–1.331) and women (OR: 1.215, 95% CI:1.061–1.390). Other risk factors included a higher baseline LDL cholesterol, higher BMI, and higher baseline eGFR (the latter two in women only). Increased SUA over 5 years were also independent risks for developing high LDL cholesterol and hypertriglyceridemia, but not for low high-density lipoprotein (HDL) cholesterol. Conclusions: This is the first study to report that an elevated SUA increases the risk for developing high LDL cholesterol, as well as hypertriglyceridemia. This may shed light into the role of SUA in cardiovascular disease. Highlights: This study clarified the relationship between serum uric acid (SUA) and lipid. High baseline SUA is an independent risk for developing high LDL cholesterol. Increased SUA over 5 years is also a risk for developing high LDL cholesterol. Increased SUA is a risk for hypertriglyceridemia, but not for low HDL cholesterol. It shows a potential mechanism in which high SUA may cause cardiovascular disease.
