Introduction: Serum lipocalin 2 serve as a marker for kidney function. Lipocalin 2 is found in both CKD and kidney injury and it rises in acute kidney injury (AKI) and in patients have faster decline in kidney function. Aims And Objectives: To nd out correlation and assess of serum Neutrophil gelatinase-associated lipocalin 2 (NGAL 2) in patients with stages 2 to 4 of Chronic Kidney disease. The aim of the study was NGAL could represent a novel, sensitive marker of kidney function in adult patients with CKD. Material And Methods: Study involved 120 patients divided in Case group (60 patients) attended medical/ urology OPD or admitted in medical/urology ward of CKD2 – CKD4 while control group – age and sex matched healthy individuals/ stage I CKD patients was taken as control. The plasma/ serum were used for serum urea, creatinine, Cystatin C and lipocalin 2 under all aseptic precaution on receiving consent. Result:The patients of CKD included in study were having glomerulonephritis (46.7%), pyelonephritis (21.7%), diabetic kidney disease (13.3%), polycystic kidney disease (1.7%) and other causes (16.7%). CKD patients demonstrated elevated serum NGAL 159.14 ± 48.73 ng/ml, together with a rise in urea 59.9 ± 17.6 mg/dL, serum creatinine 1.56 ± 0.97 mg/dL and Cystatin C 199 ± 113 ng/ml as compared to control have serum NGAL 76.31 ± 26.34 ng/ml, urea 22.3 ± 5.7 mg/dL, serum creatinine 0.75 ± 0.14 mg/dL and Cystatin C 76 ± 17 ng/ml (P value <0.05). Conclusion: Serum NGAL closely correlates with serum Cystatin C, creatinine, and eGFR, and serve as a potential early and sensitive marker of impaired kidney function/ kidney injury.

Introduction: Most genetic variants for chronic kidney disease (CKD) have been identified in non-coding regions, with functional roles that are difficult to interpret. Hypothesis: A whole exome sequencing study focusing on coding variants will reveal novel mechanisms of kidney function and CKD. Methods: We performed whole exome sequencing analyses of cystatin C among 29,789 UK Biobank (UKB) participants with further confirmation among 4,297 white and 607 African American participants of the Health and Retirement Study (HRS). Conditional analyses for loci achieving exome-wide significance ( P <3.5х10 -7 ) were conducted in UKB using both the exome (n=29,789) and imputed GWAS data (n=295,122). Genomic findings were tested for relevance to baseline estimated glomerular filtration rate (eGFR) and stringently adjudicated CKD progression events among participants of the Chronic Renal Insufficiency Cohort (CRIC) by race and smoking status, using a base model and a full model ( Table ). Results: We identified a common missense variant, CST9 rs2983640, in a previously reported locus ( CST3 intron rs13038305), of which the minor G allele was associated with lower serum cystatin C level (UKB: beta=-0.03 mg/L, P =7.64х10 -92 ; HRS whites: beta=-0.05 mg/L, P =4.71х10 -6 ; HRS African Americans: beta=-0.03 mg/L, P =0.64; and multi-ethnic meta-analysis beta=-0.03 mg/L, P =2.46х10 -91 ). After controlling for the CST3 variant, the G allele was associated with higher cystatin C level (UKB exome: beta=0.003 mg/L, P =0.04; UKB GWAS: beta=0.003 mg/L, P =1.47х10 -10 ). Similar associations were identified in white CRIC participants (direct effect: beta=-0.05 mg/L, P =0.005; conditional effect: beta=0.004 mg/L, P =0.86). The CST9 rs2983640 G allele was associated with lower baseline eGFR (base model beta=-0.33 ml/min/1.73 m 2 , P =1.98х10 -6 ) and higher hazard of developing CKD progression independent of the reported CST3 variant ( Table ). Conclusions: We identified a novel missense variant influencing cystatin C level and CKD progression.

Introduction: Chronic kidney disease (CKD) progression assessed by estimated GFR from creatinine (eGFR-Cr) is a risk factor for cardiovascular disease and end-stage renal disease (ESRD) and has been proposed as a surrogate endpoint for clinical trials. It is unclear if CKD progression assessed by change in different filtration markers has similar risk associations with ESRD. Hypothesis: We hypothesized that percent change in novel kidney filtration markers (β 2 -microglobulin and cystatin C) over a 6-year period would be independently associated with increased risk of ESRD during 15 years of follow-up, similar to the risk seen with change in eGFR-Cr. Methods: We conducted prospective analyses of the ARIC study (N=9,703). β 2 -microglobulin, cystatin C, and creatinine were measured at study visits 1 (1990-92) and 2 (1996-98). Incident ESRD (kidney dialysis or transplant) was defined as entry into the U.S. Renal Data System registry between study visit 2 and September 30, 2011. Cox proportional hazards regression was used to estimate the association between percent change in filtration marker and incident ESRD, adjusting for demographics, kidney disease risk factors, and 1 st measurement of the filtration marker. Results: During a median follow-up of 13.1 years, there were 142 incident ESRD cases. Median eGFR-Cr was 97.3 mL/min/1.73 m 2 at 1 st measurement and 89.0 mL/min/1.73 m 2 at 2 nd measurement. Percent change in eGFR-Cr was moderately correlated with percent change in the inverse of β 2 -microglobulin (r = 0.34) and the inverse of cystatin C (r = 0.36). Progression of CKD (10-25% and >25% decline in filtration function) was associated with increased ESRD risk, with novel markers (β 2 -microglobulin, cystatin C) showing an association at least as strong as the creatinine and eGFR-Cr estimates (Table). Conclusions: CKD progression assessed using novel filtration markers is independently associated with ESRD risk, suggesting the potential utility of measuring change in β 2 -microglobulin and cystatin C in clinical trials.
