Abstract
Aims
To investigate the associations between baseline/changes in serum uric acid (sUA) and the risks for cardiovascular/microvascular outcomes and mortality in a type 2 diabetes cohort.
Methods
Baseline sUA was measured in 685 individuals, and 463 had a second sUA measurement during follow-up; sUA was analyzed as a continuous variable and categorized into sex-specific tertile subgroups and low/high levels (>4.5 mg/dl women; >5.5 mg/dl men). The risks associated with baseline sUA and its changes were examined by Cox analyses for all outcomes.
Results
Median follow up was 10.7 years, there were 173 major cardiovascular events (MACEs), 268 all-cause deaths, 127 microalbuminuria, 104 renal failure, 160 retinopathy and 178 peripheral neuropathy outcomes. Baseline sUA was predictor of all outcomes, except all-cause mortality and retinopathy. In tertile and high/low sUA analyses, the hazard ratios (HRs) varied from 1.6 (microalbuminuria development) to 2.4 (MACEs; cardiovascular mortality). There was interaction with sex for MACEs, an increased risk was observed in women (HR: 2.6), but not in men (HR: 1.2). Changes in sUA were associated with the renal failure (HR: 2.4).
Conclusions
In a prospective cohort, high baseline sUA was a predictor of cardiovascular, renal and peripheral neuropathy. However, sUA changes were only predictor of renal failure.
期刊介绍：
Journal of Diabetes and Its Complications (JDC) is a journal for health care practitioners and researchers, that publishes original research about the pathogenesis, diagnosis and management of diabetes mellitus and its complications. JDC also publishes articles on physiological and molecular aspects of glucose homeostasis.
The primary purpose of JDC is to act as a source of information usable by diabetes practitioners and researchers to increase their knowledge about mechanisms of diabetes and complications development, and promote better management of people with diabetes who are at risk for those complications.
Manuscripts submitted to JDC can report any aspect of basic, translational or clinical research as well as epidemiology. Topics can range broadly from early prediabetes to late-stage complicated diabetes. Topics relevant to basic/translational reports include pancreatic islet dysfunction and insulin resistance, altered adipose tissue function in diabetes, altered neuronal control of glucose homeostasis and mechanisms of drug action. Topics relevant to diabetic complications include diabetic retinopathy, neuropathy and nephropathy; peripheral vascular disease and coronary heart disease; gastrointestinal disorders, renal failure and impotence; and hypertension and hyperlipidemia.
