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: Adding cystatin C to serum creatinine improves accuracy of estimated glomerular filtration rate (eGFR), but the impact on detection, staging and prognosis of chronic kidney disease (CKD) across diverse populations has not been determined. Methods: Meta-analyses including 11 general population cohorts (N=90,750 participants) and 5 CKD cohorts (N=2,960) with standardized serum creatinine and cystatin C at baseline. We compared associations of baseline GFR estimated by CKD-EPI equations using creatinine (eGFR cr ) vs. cystatin C (eGFR cys ) with mortality (13,202 deaths from 15 cohorts) and incident end-stage renal disease (ESRD) (1,654 cases from 7 cohorts) during mean follow-up of 7.7 years and studied prognostic consequences of reclassification. Results: In the general population cohorts, mean eGFRs were 85 ml/min/1.73m 2 for both equations but prevalence of eGFR<60 ml/min/1.73m 2 was higher for eGFR cys vs. eGFR cr (13.7% vs. 9.7% [12,403 vs. 8,833 of 90,750]). Across all eGFR cr categories (≥90, 60-89, 45-59, 30-44, 15-29, and <15 ml/min/1.73m 2 ), upward and downward reclassification by eGFR cys was associated with lower and higher risk, respectively; net reclassification improvement for eGFR cys compared with eGFR cr was 0.23 (0.18-0.28) for mortality and 0.10 (0.00-0.21) for ESRD. Among participants with eGFR cr 45-59 ml/min/1.73m 2 (N=6,358), ~40% were reclassified to higher eGFR cys categories and had lower risks of mortality (adjusted hazard ratio 0.66; 95% CI 0.57-0.77) and ESRD (0.20; 0.08-0.53) compared to those who were not reclassified. Among participants with eGFR cr 60-89 ml/min/1.73m 2 (N=43,630), ~13% were reclassified to lower eGFR cys categories and had higher risk for mortality (1.57; 1.39-1.78) and ESRD (2.66; 1.52-4.67) compared to no reclassification. The results for CKD cohorts were largely similar. Conclusions: Cystatin C strengthens the association of eGFR with risk across diverse populations providing a potentially useful adjunct to eGFR cr for detection and staging of CKD.

Association of oxidative stress and serum prolidase activity (SPA) has been reported in many chronic diseases. The study was aimed at evaluating the correlation of glucose and creatinine to SPA and oxidative stress in patients with diabetic nephropathy (DN) and end stage renal disease (ESRD) concerned with T2DM. 50 healthy volunteers, 50 patients with T2DM, 86 patients with DN, and 43 patients with ESRD were considered as control-1, control-2, case-1, and case-2, respectively. Blood glucose, creatinine, SPA, total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI) were measured by colorimetric tests. SPA, TOS, and OSI were significantly increased in case-1 and case-2 than control-1 and control-2, while TAS was significantly decreased(P<0.001). Blood glucose was linearly correlated to SPA, TOS, TAS, and OSI in control-2, case-1 and case-2(P<0.001). Serum creatinine was linearly correlated with SPA, TOS, TAS and OSI in control-2 and case-1(P<0.001). In case-2, serum creatinine was significantly correlated with SPA only(P<0.001). Thus, the study concluded that SPA and oxidative stress significantly correlated with blood glucose and creatinine. SPA, TOS, TAS, and OSI can be used as biomarkers for diagnosis of kidney damage.

Abstract Background End-stage renal disease (ESRD) patients are at substantially higher risk for developing cognitive impairment compared with the healthy population. Dialysis is an essential way to maintain the life of ESRD patients. Based on previous research, there did not provide an uncontested result whether cognition was improved or worsened during dialysis. Methods To explore the impact of dialysis treatment on cognitive performance, we recruited healthy controls (HCs), ESRD patients before dialysis initiation (bESRD) and those undergoing maintenance hemodialysis (mESRD). All ESRD patients performed a serious of blood biochemistry tests (hemoglobin, urea, cystatin C, Na+, K + and parathyroid hormone). Neuropsychological tests were used to measure cognitive function. By using diffusion tensor imaging and graph-theory approaches, the topological organization of the whole-brain structural network was investigated. Generalized linear models (GLMs) were performed to investigate blood biochemistry predictors of the neuropsychological tests and the results of graph analyses in mESRD and bESRD groups. Results Neuropsychological analysis showed mESRD exhibited greater cognitive function than bESRD, but both were worse than HCs. Whole-brain graph analyses revealed that increased global efficiency and normalized shortest path length remained in the bESRD and mESRD than the HCs. Besides, lower normalized clustering coefficient was in bESRD relative to the HCs and mESRD. For the GLMs analysis, only the Cystatin C level was significantly associated with the average fiber length of rich club connections in bESRD. Conclusions Our study revealed that dialysis had a limited effect on cognitive improvement. Cystatin C may be a risk feature of cognitive decline of bESRD.
