Serum cystatin C is a new promising marker of renal function. The aim of this study was to analyze serum cystatin C as a better predictor of renal function in diabetic nephropathy. In 60 diagnosed diabetic patients, serum cystatin C and serum creatinine were assessed. Glomerular filtration rate was estimated based on the cystatin C concentration according to Cockcroft- Gault formula and based on serum creatinine concentration according to Larsson formula. DTPA-GFR (Diethylenetriamene pentaacetate Renogram) was done as reference standard. The cross tabulation of DTPA-GFR was done with eGFR- creatinine and eGFRcystatin C. The calculated sensitivity, specificity and accuracy of eGFR- creatinine were 85%, 87.2% and 85% respectively. The eGFR- cystatin C showed higher sensitivity, specificity and accuracy than eGFR- creatinine in studied diabetic subjects. The cystatin C showed more significant correlation, r=0.78, p<0.001 than serum creatinine, r=0.59, p<0.001 with DTPA-GFR in diabetic patients. This study demonstrates that serum cystatin C may be used for early prediction for renal function impairment in diabetic kidney disease.

Background: Chronic kidney disease (CKD) is a pathophysiologic process characterised by a decrease in nephron number and function, which often leads to end-stage renal disease (ESRD). Serum plasma cystatin C is a new test for determining kidney function. Its accuracy in determining the efficacy of haemodialysis in patients with end-stage renal disease has yet to be determined. Serum cystatin C, which is formed at a constant rate by all nucleated cells and filtered freely by the glomerulus, is neither secreted nor reabsorbed, and is unaffected by non-renal influences. Materials and Methods: This study was a comparative study, conducted in the nephrology Department at DMMC & SMHRC, Nagpur in collaboration with ABVRH and JNMC Wardha, Sawangi (Meghe) during September 2020 to March 2021. Total 25 patient (End stage renal disease) included for the present study, the age group 30-60 years with 17 male patients and 08 female patients. Result: Serum creatinine concentration in the before hemodialysis with 8.72±3.00 and for the after hemodialysis 3.20±1.18(P < 0.0001). The serum cystatin C concentration in the before hemodialysis 5.50±2.09 and for the after hemodialysis 8.7±1.75(P < 0.0001). the process of hemodialysis leads to a significantly low in a serum creatinine concentration as compared to before hemodialysis. The serum cystatin C concentration significantly increase in the after hemodialysis patient as compared to before hemodialysis. Conclusion: Hemodialysis adequacy cannot be determined using serum cystatin C. It does, however, serve as a surrogate marker of dialysis inadequacy, particularly when low flux membranes are used. Routine examination of serum cystatin C in hemodialysis patients will help in the monitoring of the patient's overall clinical condition.

Background: Diabetic kidney disease is the leading cause of premature death in young diabetic patients. Detection of diabetic kidney disease as early as possible in the disease process currently offers the best chance of delaying or possibly preventing progression to end-stage renal disease. The present study was aimed to evaluate utility of serum cystatin C based eGFR for early diagnosis of diabetic kidney disease.Methods: Diagnosed patients of type 2 diabetes mellitus having frank proteinuria were excluded. Patients without proteinuria were tested for microalbuminuria.  50 patients having microalbuminuria were tested for 24 hour urine creatinine, serum creatinine and serum cystatin C. Both cystatin C based eGFR and eGFR by Cockcroft and Gault equation were compared with standard GFR by 24 hour urine Creatinine clearance respectively.Results: There was statistically significant positive correlation between cystatin C based eGFR and standard GFR by 24 hr Creatinine clearance (r=0.87). For eGFR by Cockcroft-Gault equation, it was 0.36 (r=0.36).Conclusions: The results of this study suggest that serum cystatin C based eGFR  measurement is a useful, practical tool for the evaluation of renal involvement in the course of diabetes. As serum creatinine values are affected by many factors like age, sex, muscle mass and diet, serum cystatin C based eGFR estimation offers a hope that diabetic kidney disease can be well prevented with appropriate interventions.

Objective This study aimed to find the effect of serum Cystatin C in early diabetic nephropathy.Method This study was conducted in Al Kindy Teaching Hospital during the period from December, 2015 to June, 2016. The study included 90 subjects (30 males and 30 females) with diabetic type 2 and 30 healthy control. Age is between 30 and 70 years. Patients were with no history of liver disease, thyroid or other endocrine diseases through clinical interviewing. They were divided in to three groups. 30 healthy controls, 30 patients with type 2 diabetes mellitus with no albuminuria (albumin excretion in urine <30 μg/ml ) and 30 patients with type 2 diabetes mellitus with micro albuminuria (albumin excretion in urine >30 μg/ml ).Results There were no significant differences in age, body mass index (BMI) among the studied groups (p > 0.05). Serum Cystatin C levels showed significant difference (p < 0.001) among studied groups, it was significantly higher in micro albuminuria than the other two groups. There was highly significant positive correlation between Cystatin C and serum creatinine (r = 0.697, p < 0.001), and a significant negative correlation between Cystatin C and GFR (r = − 0.455, p = 0.011) and show significant positive correlation between Cystatin C and urine albumin (r = 0.526, p = 0.003 ) in type 2 diabetic patients with micro albuminuria.Conclusion Cystatin C is negatively correlated with the amount of GFR, so that Cystatin C considered reliable and sensitive marker for identifyingchanges in GFR. In type 2 diabetes mellitus with micro albuminuria serum Cystatin C level considered predict marker for renal failure.
