Peritoneal dialysis complication

Introduction:
Several randomised controlled trials have demonstrated that novel oral anticoagulants (NOACs) are safer compared to vitamin K antagonists for the management of non valvular atrial fibrillation (NVAF) to prevent thromboembolic events, in the general population. There is a growing interest in the use of apixaban in patients with End-Stage Renal-Disease (ESRD) undergoing peritoneal dialysis but there is a lack of randomised data in this population.
Design: APIDP2 is a prospective parallel randomised, open-label, blinded endpoint trial.
Participants: Patients with ESRD undergoing chronic Peritoneal Dialysis who have NVAF.
Setting: A total of 178 participants will be recruited from 20 French peritoneal dialysis centers.
Intervention: Eligible patients will be randomly assigned to receive either apixaban at a reduced dose 2.5mg twice daily (dose determined with the previous pharmacokinetic study APIDP1 of apixaban in PD patients) or dose-adjusted to INR target [2-3] coumadin therapy. Anticoagulation to prevent thromboembolic events will be initiated or changed according to the randomisation for a duration of one year.
The primary outcome is a major or clinically relevant non-major bleeding from randomisation up to Month 12, assessed according to ISTH score. Secondary outcomes encompass an efficacy composite criterion combining stroke or TIA, cardiovascular death, and thrombosis including myocardial infarction cumulated at 12 months. Bleeding events will be also classified according to GUSTO and TIMI criteria and pharmacodynamics outcomes will evaluate the time within the INR target range of [2-3] in the warfarin arm over one year, and AntiXa apixaban activity in case of bleeding events and at 1, 6, and 12 months of follow-up in the apixaban arm.
Primary outcome analysis: To demonstrate that apixaban is safer than warfarin at one year, assuming two interim analyses after 60 and 118 patients, a bilateral alpha risk of 5% and a power of 80%, 178 patients are needed in this randomised trial (effect size found in the ARISTOTLE study among patients with CrCl [25-30]ml/min), i.e. 89 patients per group.

Empagliflozin, a new class of diabetes medication, has demonstrated a reduction in renal function decline among patients with chronic kidney disease, regardless of their diabetes status. However, all previous studies excluded dialysis patients. Patients starting dialysis may still produce a certain amount of urine. Importantly, patients with better preserved residual kidney function tend to have better control of blood pressure and volume status, improved nutrition status, higher quality of life and reduced mortality rate.
The purpose of this study is to learn about the safety of empagliflozin in patients on peritoneal dialysis, in preparation for a future large clinical trial. Participants who newly initiate peritoneal dialysis will be randomly allocated to either empagliflozin on top of standard of care, or standard of care alone. Over a follow-up period of six months, the investigators will collect information on urine volume, blood pressure and glucose control. Safety, tolerability and drug compliance of empagliflozin will also be evaluated. If empagliflozin is found to be safe and well tolerated in patients on peritoneal dialysis, further large-scale randomized controlled trial may be conducted to evaluate its impact on residual kidney function and other relevant clinical outcomes.
