Function Assessment

Background: Renal dysfunction negatively impacts survival in acute coronary syndrome patients. The Berlin Initiative Study creatinine-based (BIScrea) equation has recently been proposed for renal function assessment in older persons. However, up to now it is unknown if the superiority of the new BIScrea equation, with respect to the most recommended chronic kidney disease epidemiology collaboration creatinine-based (CKD-EPIcrea) formula, would translate into better risk prediction of adverse events in older patients with acute coronary syndrome. Objectives: To study the impact of using estimated glomerular filtration rate calculated according to the BIScrea and CKD-EPIcrea equations on mortality in acute coronary syndrome patients aged 70 years and over. Methods: Retrospectively, between 2011 and 2016, a total of 2008 patients with acute coronary syndrome (64% men; age 79±7 years) were studied. Follow-up was 18±10 months. Measures of performance were evaluated using continuous data and stratifying patients into three estimated glomerular filtration rate subgroups: ≥60, 59.9–30 and <30 mL/min/1.73 m2. Results: The two formulas afforded independent prognostic information over follow-up. However, risk prediction was most accurate using the BIScrea formula as evaluated by Cox proportional hazards models (hazard ratio (for each 10 mL/min/1.73 m2 decrease) 1.47 vs. 1.27 with the CKD-EPI equation; P<0.001 for comparison), c-statistic values (0.69 vs. 0.65, respectively; P=0.04 for comparison) and Bayesian information criterion. Net reclassification improvement based on the estimated glomerular filtration rate categories significantly favoured BIScrea +9 (95% confidence interval 2–16%; P=0.02). Conclusions: Our findings suggest that the BIScrea formula may improve death risk prediction more than the CKD-EPIcrea formula in older patients with acute coronary syndrome.

Background: Persons with morbid obesity are at increased risk for end-stage kidney disease, and prior studies have shown an association between bariatric surgery and improvements in creatinine-based estimated glomerular filtration rate (eGFR cr ). However, eGFR cr could be biased by loss of muscle mass after surgery, and creatinine-cystatin C estimated glomerular filtration rate (eGFR cr-cyc ) has been shown to be more accurate in this setting. Methods: We matched 144 patients who underwent bariatric surgery on pre-surgery age, sex, race, body mass index (BMI), and eGFR cr with 144 morbidly obese non-surgery patients at Geisinger with serial biobanked serum samples. We measured filtration markers (creatinine, cystatin C, beta-2 microglobulin [B2M] and beta-trace protein [BTP], and calculated eGFR cr-cyc using the CKD-EPI combined equation. Using mixed effects models with random intercepts, we compared changes in filtration markers and eGFR cr-cyc between surgery and non-surgery groups. Results: Mean (SD) values for age, BMI, and eGFR cr were 48.2 (10.4) years, 45.2 (6.3) kg/m 2 , and 91.7 (17.5) ml/min/1.73m 2 ; 87.5% were female, 0.7% were black, 50.3% had hypertension, and 41.0% had type 2 diabetes. Mean eGFR cr-cyc slope in the surgery group was -0.41 ml/min/1.73m 2 /yr (95% CI: -0.74, -0.08) over a mean follow-up of 9.2 (1.4) years, compared to -1.43 ml/min/1.73m 2 /yr in the non-surgery group over a mean follow-up of 8.2 (1.1) years. Bariatric surgery was associated with a 1.02 ml/min/1.73m 2 /yr slower decline in eGFR cr-cyc , and smaller increase in all 4 filtration markers (p< 0.02 for all comparisons). Conclusions: Bariatric surgery is associated with slower decline in kidney function, as assessed by eGFR cr-cyc , B2M and BTP.

ObjectiveVariability in estimated glomerular filtration rate (eGFR) has been associated with adverse outcomes in patients with diabetes or chronic kidney disease (CKD). However, no previous study has explored the relationship between eGFR variability and type 2 diabetes incidence.Research design and methodsIn this nationwide, longitudinal, cohort study, we investigated the association between eGFR variability and type 2 diabetes risk using the Korean National Health Insurance Service datasets from 2002 to 2017. eGFR variability was calculated using the variability independent of the mean (eGFR-VIM), coefficient of variation (eGFR-CV), standard deviation (eGFR-SD) and average real variability (eGFR-ARV).ResultsWithin 7 673 905.58 person-years of follow-up (mean follow-up: 3.19 years; n=2 402 668), 11 981 cases of incident type 2 diabetes were reported. The HRs and 95% CIs for incident type 2 diabetes increased according to advance in quartiles of eGFR-VIM (HR (95% CI): Q2, 1.068 (1.009 to 1.130); Q3, 1.077 (1.018 to 1.138); Q4, 1.203 (1.139 to 1.270)) even after adjusting for confounding factors including mean eGFR and mean fasting plasma glucose levels. The subgroup analyses according to risk factors as well as analyses using eGFR-CV, eGFR-SD and eGFR-ARV showed consistent results. The association between increased eGFR variability and type 2 diabetes risk was more prominent in men, individuals with dyslipidemia and those with CKD as shown in the subgroup analysis (p for interaction <0.001).ConclusionsIncreased eGFR variability may be an independent predictor of type 2 diabetes and might be useful for risk stratification of individuals without diabetes.

Abstract Cognitive dysfunction is closely related to aging and chronic kidney disease (CKD). However, the association between renal function changes and the risk of developing cognitive impairment has not been elucidated. This longitudinal cohort study was to determine the influence of annual percentage change in estimated glomerular filtration rate (eGFR) on subsequent cognitive deterioration or death of the elderly within the community. A total of 33,654 elders with eGFR measurements were extracted from the Taipei City Elderly Health Examination Database. The Short Portable Mental Status Questionnaire was used to assess their cognitive progression at least twice during follow-up visits. Multivariable Cox regression models were used to estimate the hazard ratio (HR) for cognitive deterioration or all-cause mortality with the percentage change in eGFR. During a median follow-up of 5.4 years, the participants with severe decline in eGFR (>20% per year) had an increased risk of cognitive deterioration (HR, 1.33; 95% confidence interval [CI], 1.08–1.72) and the composite outcome (HR, 1.17; 95% CI, 1.03–1.35) when compared with those who had stable eGFR. Severe eGFR decline could be a possible predictor for cognitive deterioration or death among the elderly. Early detection of severe eGFR decline is a critical issue and needs clinical attentions.

Objectives: Our objectives were to evaluate the long-term renal function after radical cystectomy (RC) and ileal conduit diversion (ICD) and to analyze year-by-year the estimated glomerular filtration rate (eGFR) and morphologic upper urinary tract changes. Materials and Methods: We retrospectively identified 214 patients who had undergone RC and ICD from 2012 to 2018, with regular postoperative follow-up visits. The eGFR was calculated using the Modification of Diet in Renal Disease equation at baseline and during follow-up. A renal function decrease was defined as a greater than 10 mL/min/1.73 m2 reduction in the estimated glomerular filtration rate. Results: The median follow-up period after RC was 24 months (range, 6-60 months). The median eGFR decreased from 64 mL/min/1.73 m2 (range, 9-125 mL/min/1.73 m2) to 61.5 mL/min/1.73 m2 (range, 8-125 mL/min/1.73 m2). A decline in renal function occurred during the first postoperative years (2.74 mL/ min/1.73 m2 and 3.95 mL/min/1.73 m2 in the first and second year, respectively), with a slight decrease in the subsequent years. The strongest predictor of an eGFR decline was CKD stage 1 or 2 (> 60 mL/min/1.73 m2). Urinary obstruction was diagnosed in 6 patients (2.8%). Among the patients who underwent prompt interventional treatment, we did not find any association with the eGFR decline. Conclusion: Patients with urinary ICD have a lifelong risk of chronic kidney disease. Regular monitoring of renal function and the morphologic upper urinary tract will permit early diagnosis and treatment of modifiable factors, avoiding irreversible kidney damage.
