Abstract
Background
Prospective studies have reported associations among various markers of inflammation and the incidence of diabetes, and it has been proposed that inflammation has a causal role in the development of diabetes. The objective of this study was to investigate the significance of serum and urine neuraminidase activity (NA) and serum and urine sialic acid (SA) level in patients with Diabetic nephropathy.
Methods
In a prospective study, 190 diabetic patients with established diabetic nephropathy, 30 type 2 diabetes patients without any diabetic related nephropathy, and 36 non-diabetic patients with diagnosed nephropathy were enrolled. Two hundred and forty healthy individuals without diabetes or kidney disease were also enrolled as control group. Fasting venous blood samples and urine samples were collected and checked for serum and urine NA and SA level.
Results
In the diabetic nephropathy group, the mean value of serum and urine NA was 64.6 ± 2.6 and 11.7 ± 1.2 mU/ml, respectively, and mean values of serum and urine SA were 93.2 ± 3.6 and 17.7 ± 1.4 mg/dl, respectively. Serum and urine NA and SA levels were significantly higher in patient with diabetic nephropathy when compared to the other groups (P < 0.001).
Conclusions
Our study suggests that there is a strong association between elevated serum and urine NA and serum and urine SA levels with the presence of diabetic nephropathy in type 2 diabetic patients. Further investigations are needed on the diagnostic and prognostic significance of these two inflammatory markers.
