Abstract Background The use of antiarrhythmic drugs in patients with chronic kidney disease (CKD) is challenging due to issues with renal clearance, drug accumulation and increased proarrhythmic risks. Since CKD is a common comorbidity with atrial fibrillation (AF), it is important to establish the efficacy and safety for antiarrhythmic drug treatment in patients with CKD. Purpose To evaluate the efficacy and safety of dronedarone in patients with AF or atrial flutter (AFL) across different stages of renal impairment. Methods In this post-hoc analysis of ATHENA (NCT00174785), a randomised, double-blind trial of dronedarone 400 mg BID vs placebo in patients with AF or AFL plus additional risk factors for death and a calculated glomerular filtration rate ≥10 mL/min, the primary outcome was time to first cardiovascular (CV) hospitalisation or death. Renal function (estimated glomerular filtration rate [eGFR]) was assessed using CKD Epidemiology Collaboration equation and patients were grouped by eGFR (10–44, 45–59, ≥60 mL/min). Log-rank testing and Cox regression were used to compare time to events between treatment groups. Results In ATHENA, 43.6% of placebo and 42.2% of dronedarone patients had mild-to-moderate CKD (Table). Median time to CV hospitalisation/death was longer in all strata for dronedarone vs placebo, reaching significance in the 45–59 and ≥60 mL/min groups (Figure 1). There was a trend towards more treatment-emergent adverse events (TEAEs), deaths and discontinuations due to TEAEs in patients with eGFR 10–44 mL/min. No clear difference in safety was seen between treatment arms except for discontinuations, which were higher with dronedarone. Conclusions This analysis confirms the efficacy of dronedarone, demonstrated in ATHENA, across different stages of renal impairment. Further assessment of safety will require larger populations of patients with CKD. Figure 1 Funding Acknowledgement Type of funding source: Private company. Main funding source(s): Sanofi

Background. The performance of various equations for estimated glomerular filtration rate (eGFR) in patients with diabetes remains controversial. We aimed to evaluate the performance of equations for eGFR in Chinese patients with diabetic nephropathy (DN). Methods. This is a retrospective study included in 308 patients with type 2 diabetes and biopsy-proven DN who were followed up at least one year. eGFR was calculated using chronic kidney disease epidemiology (CKD-EPI) equations based on serum creatinine (eGFRCKD-EPI-Cr), cystatin C (eGFRCKD-EPI-CysC), and joint equations (eGFRCKD-EPI-Cr-CysC), respectively. End-stage kidney disease was defined by initiation of renal replacement therapy. The eGFR concordance between equations was assessed by Bland-Altman plots. Log-rank and multivariable logistic regression were employed to evaluate the performance of equations. Results. Overall, the proportion of patients with eGFR<60 mL/min/1.73m2 was 53%, 70%, and 61% by the equations of eGFRCKD-EPI-Cr, eGFRCKD-EPI-CysC, and eGFRCKD-EPI-Cr-CysC, respectively. Higher disconcordance was observed between equations when eGFR>60 mL/min/1.73m2. Compared with eGFRCKD-EPI-Cr, 39% of patients were reclassified (reclassified group) from CKD 1-2 stages to CKD 3-5 stages by eGFRCKD-EPI-CysC and they presented significantly longer diabetic duration, heavier proteinuria, advanced pathological lesions, and poorer kidney outcomes. Multivariable logistic regression indicated cystatin C was independently associated with advanced glomerular classifications. Conclusion. eGFR equations incorporating cystatin C are superior to eGFR based on creatinine alone for detecting kidney injury in the early stage. The independent association between cystatin C and glomerular classifications might contribute to it.

Abstract Background Direct oral anticoagulants (DOACs) pharmacokinetics depends on estimated glomerular filtration rate (eGFR), whose estimation is crucial for optimal risk/benefit balance. Aims To assess the concordance among different eGFR formulas and the potential impact on DOACs prescription appropriateness and bleeding risk in oldest hospitalized patients. Methods Post hoc analysis of a single-centre prospective cohort study. eGFR was calculated by creatinine-based (MDRD, CKD-EPICr, BIS1) and creatinine–cystatin-C-based (CKD-EPIComb and BIS2) formulas. Patients were stratified according to eGFR [severely depressed (SD) 15–29; moderately depressed (MD) 30–49; preserved/mildly depressed (PMD): ≥ 50 ml/min/1.73 m2]. Concordance between the different equations was assessed by Cohen’s kappa coefficient. Results Among AF patients, 841 (59.2% women, mean age 85.9 ± 6.5 years) received DOACs. By CKD-EPICr equation, 135 patients were allocated in the SD, 255 in the MD and 451 in the PMD group. The concordance was excellent only between BIS 2 and CKD-EPIComb and MDRD and CKD-EPICr, while was worse (from good to poor) between the other formulas. Indeed, by adding cystatin-C almost over 1/3 of the patients were reallocated to a worse eGFR class. Bleeding prevalence increased by 2–3% in patients with discordant eGFR between formulas, reallocated to a worse chronic kidney disease (CKD) stage, although without reaching statistical significance. CKD-EPIComb resulted the best predictor of bleeding events (AUROC 0.71, p = 0.03). Discussion This study highlights the variability in CKD staging according to different eGFR formulas, potentially determining inappropriate DOACs dosing. Although the cystatin-C derived CKDEPIComb equation is the most accurate for stratifying patients, BIS1 may represent a reliable alternative.

Abstract Objectives Diabetic nephropathy is a serious and a common complication of diabetes that can lead to end stage renal disease among children living with type 1 diabetes, thus an early and accurate method of diagnosis that allows timely intervention is of high importance. This study aimed to evaluate the role of magnetic resonance diffusion weighted imaging in diagnosis of diabetic nephropathy in children with type 1 diabetes. Methods This prospective, observational, case control study included 30 children with type 1 diabetes and 30 matched healthy controls attending the outpatient clinics in Mansoura University Children’s Hospital. All were subjected to magnetic resonance DWI of the renal parenchyma and their glomerular filtration rate (GFR) was estimated, along with micro albumin in 24 h urine collection and HbA1c in patients with diabetes. Results Children with diabetes who were positive for microalbuminuria had significantly lower apparent diffusion coefficient value compared to Children with diabetes who were negative for microalbuminuria (p = 0.034) as well as controls (p = 0.001). Among children with type 1 diabetes, apparent diffusion coefficient had significant positive correlation with estimated glomerular filtration rate (r = 0.491, p = 0.006) and negative correlation with microalbuminuria (r = −0.437, p = 0.016). Conclusion Magnetic resonance DWI of the renal parenchyma is correlated with estimated glomerular filtration rate (eGFR) in children with type 1 diabetes and can detect GFR deterioration even in presence of normal albumin excretion.
