INTRODUCTION: Hypertriglyceridemia, a component of the metabolic syndrome, is a known independent predictor of albuminuria and chronic kidney disease (CKD) in the general population. Previous studies have shown that the relationship of triglycerides (TGs) with outcomes changes across stages of CKD. Our objective was to examine the association of TG independent of other metabolic syndrome components with renal outcomes in diabetic patients with or without CKD.

METHODS: This retrospective cohort study included diabetic US veteran patients with valid data on TGs, estimated glomerular filtration rate (eGFR), and albuminuria (urinary albumin/creatinine ratio) between fiscal years 2004 and 2006. Using Cox models adjusted for clinical characteristics and laboratory markers, we evaluated the relationship of TG with incident albuminuria (stratified by eGFR category) and based on eGFR (stratified by baseline albuminuria categories). To evaluate the relationship of TG with time to end-stage renal disease (ESRD), we stratified models by baseline CKD stage (eGFR category) and baseline albuminuria stage ascertained at time of TG measurement.

RESULTS: In a cohort of 138,675 diabetic veterans, the mean ± SD age was 65 ± 11 years old and included 3% females and 14% African Americans. The cohort also included 28% of patients with non-dialysis-dependent CKD (eGFR <60 mL/min/1.73 m2), as well as 28% of patients with albuminuria (≥30 mg/g). The median (IQR) of serum TG was 148 (100, 222) mg/dL. We observed a slight positive linear association between TG and incident CKD after adjustment for Case-Mix and Laboratory variables among non-albuminuric and microalbuminuric patients. The relationship of high TG trended towards a higher risk of ESRD in CKD 3A non-albuminuric patients and in CKD 3A and 4/5 patients with microalbuminuria.

CONCLUSION: In a large cohort, we have shown that elevated TGs are associated with all kidney outcomes tested independently of other metabolic syndrome components in diabetic patients with normal eGFR and normal albumin excretion rate, but the association is weaker in some groups of diabetic patients with preexisting renal complications.
