Introduction: Determination of renal function is particularly important when prescribing antibiotics to elderly patients. This study aims to determine the correlation between estimated creatinine clearance and the estimated glomerular filtration rate, for a hospitalized population of very elderly patients, and to audit antibiotic prescribing errors.Material and Methods: Retrospective cohort study of all patients ≥ 80 years hospitalized with antibiotic. Creatinine clearance was calculated using Cockcroft-Gault equation and estimated glomerular filtration rate by Modification of Diet in Renal Disease Study and Chronic Kidney Disease Epidemiology Collaboration equations. Dosing errors were determined through adjustment of daily define dose to renal function.Results: The study included 589 patients. The correlation of Cockcroft-Gault with Modification of Diet in Renal Disease and Chronic Kidney Disease Epidemiology Collaboration was r = 0.98 and 0.96 for the minimum serum creatinine, and 0.97 and 0.93 for the maximum serum creatinine. Based on Cockcroft-Gault, there were errors in the daily defined dose in 45% in the minimum serum creatinine, and 52% in the maximum serum creatinine day. There was a discrepancy in the recording of errors of 14% to 16% when Cockcroft-Gault was compared with Modification of Diet in Renal Disease and Chronic Kidney Disease Epidemiology Collaboration.Discussion: There was a good correlation of Cockcroft-Gault with the estimated glomerular filtration rate by Modification of Diet in Renal Disease or Chronic Kidney Disease Epidemiology Collaboration. Regardless of the equation used to estimate renal function there was a high rate of antibiotic dosing errors documented in this population.Conclusion: This study supports the maintenance of the Cockcroft-Gault equation for drug dosing in the very elderly population. Further studies are needed to investigate underlying causes of prescribing errors.

Abstract BACKGROUND Our objective of this study was to determine if rate of estimated glomerular filtration rate (eGFR) decline and its intensity was associated with cardiovascular risk and death in patients with hypertension whose baseline eGFR was higher than 60 ml/minute/1.73 m2. METHODS This study comprised 2,516 patients with hypertension who had had at least 2 serum creatinine measurements over a 4-year period. An eGFR reduction of ≥10% per year has been deemed as high eGFR and a reduction in eGFR of less than 10% per year as a low decline. The end points were coronary artery disease, stroke, transitory ischemic accident, peripheral arterial disease, heart failure, atrial fibrillation, and death from any cause. Cox regression analyses adjusted for potentially confounding factors were conducted. RESULTS A total of 2,354 patients with low rate of eGFR decline and 149 with high rate of eGFR decline were analyzed. The adjusted model shows that a −10% rate of eGFR decline per year is associated with a higher risk of the primary end point (HR 1.9; 95% CI 1.1–3.5; P = 0.02) and arteriosclerotic vascular disease (HR 2.2; 95% CI 1.2–4.2; P < 0.001) in all hypertensive groups. The variables associated to high/low rate of eGFR decline in the logistic regression model were serum creatinine (OR 3.35; P < 0.001), gender, women (OR 15.3; P < 0.001), tobacco user (OR 1.9; P < 0.002), and pulse pressure (OR 0.99; P < 0.05). CONCLUSIONS A rate of eGFR decline equal to or higher than −10% per year is a marker of cardiovascular risk for patients with arterial hypertension without chronic kidney disease at baseline. It may be useful to consider intensifying the global risk approach for these patients.

Although the important role of fibroblast growth factor (FGF)23 on cardiac remodeling has been suggested in advanced chronic kidney disease (CKD), little is known about serum (s)FGF23 levels in patients with heart failure (HF) due to nonischemic cardiac disease (NICD) and early CKD. The present study aimed to investigate sFGF23 levels in NICD patients and identify the responsible factors for the elevation of sFGF23 levels. We prospectively measured sFGF23 levels in consecutive hospitalized NICD patients with early CKD (estimated glomerular filtration rate ≥ 40 ml·min−1·1.73 m−2) and analyzed the data of both echocardiography and right heart catheterization. Of the 156 NICD patients (estimated glomerular filtration rate range: 41–128 ml·min−1·1.73 m−2), the most severe HF symptom (New York Heart Association class III-IV, 53% vs. 33%, P = 0.015) was found in the above median sFGF23 (39.1 pg/ml) group compared with the below median sFGF23 group. sFGF23 levels were higher in patients with HF hospitalization history compared with those without HF [median: 46.8 (interquartile range: 38.8–62.7) vs. 34.7 (interquartile range: 29.6–42.4) pg/ml, P < 0.0001]. In the multivariate analysis, HF hospitalization was independently related to elevated sFGF23 levels ( P = 0.022). Both systolic dysfunction and high plasma aldosterone concentration were identified as predictors of high sFGF23 levels ( P < 0.05). Among the neurohormonal parameters, elevated sFGF23 levels were the only factor to predict a declining left ventricular ejection fraction ( P = 0.001). These findings suggest that the progression of HF per se contributes to the elevation of sFGF23 levels even in the early stages of CKD, which leads to further myocardial dysfunction, potentially creating a vicious cycle.
