Background

Serum cystatin C level is a more sensitive marker of renal dysfunction than serum creatinine level. Serum cystatin C level was recently reported to predict the development of cardiovascular disease. This study was performed to evaluate whether the cystatin C level is associated with coronary artery disease (CAD), independent of diabetic nephropathy.

Methods

We conducted a case-control study to assess the relationship between serum cystatin C level and coronary artery disease in diabetic patients. Among 460 diabetic patients, 38 diabetic patients had CAD. The control group consisted of 38 diabetic patients who were matched to cases by age, sex, and presence/absence of diabetic nephropathy. Serum cystatin C level was measured in stored samples.

Results

Serum cystatin C level was significantly higher in patients with diabetic nephropathy, both in CAD and non-CAD patients. However, serum cystatin C level did not differ between CAD and non-CAD patients, regardless of diabetic nephropathy.

Conclusion

Serum cystatin C level is a marker of renal dysfunction, but not coronary artery disease, in diabetic patients.

Abstract PDF

BACKGROUND
Accumulating evidence has suggested that nitric oxide (NO) is involved in the regulation of insulin sensitivity in skeletal muscle. Recent studies also suggested NO as an important molecule regulating mitochondrial biogenesis. This study examined the effect of the NO donor, 3-morpholinosydnonimine (SIN-1), on glucose metabolism in skeletal muscle and tested the hypothesis that NO's effect on glucose metabolism is mediated by its effect on mitochondrial function. METHODS: In Sprague-Dawley (SD) rats treated with SIN-1 for 4 weeks, insulin sensitivity was measured by a glucose clamp study. Triglyceride content and fatty acid oxidation were measured in the skeletal muscle. In addition, mitochondrial DNA content and mRNA expression of mitochondrial biogenesis markers were assessed by real-time polymerase chain reaction and expression of insulin receptor substrate (IRS)-1 and Akt were examined by Western blot analysis in skeletal muscle. In C2C12 cells, insulin sensitivity was measured by 2-deoxyglucose uptake and Western blot analysis was used to examine the expression of IRS-1 and Akt. RESULTS: SIN-1 improved insulin sensitivity in C2C12 cells and skeletal muscles of SD rats. In addition, SIN-1 decreased triglyceride content and increased fatty acid oxidation in skeletal muscle. Mitochondrial DNA contents and biogenesis in the skeletal muscle were increased by SIN-1 treatment. Moreover, SIN-1 increased the expression of phosphor-IRS-1 and phosphor-Akt in the skeletal muscle and muscle cells. CONCLUSION: Our results suggest that NO mediates glucose uptake in skeletal muscle both in vitro and in vivo by improving mitochondrial function and stimulating insulin signaling pathways.
