Background:Combination therapy with isosorbide dinitrate (ISD) and hydralazine (HY) reduces heart failure mortality. The safety and tolerability in individuals requiring maintenance hemodialysis (HD) is unknown. Methods:., requiring hospitalization or emergency room visit), and recurrent intra-dialytic hypotension. Efficacy signals included change in mitral annular E' velocity by tissue Doppler echocardiography and change in left ventricular coronary flow reserve on positron emission tomography. Results:=0.19. Conclusions:ISD/HY appears to be well tolerated in patients being treated with maintenance HD, but headache and gastrointestinal side effects occur more frequently with ISD/HY compared with placebo.

Background:The COVID-19 pandemic strained hospital resources in New York City, including those for providing dialysis. New York University Medical Center and affiliations, including New York City Health and Hospitals/Bellevue, developed a plan to offset the increased needs for KRT. We established acute peritoneal dialysis (PD) capability, as usual dialysis modalities were overwhelmed by COVID-19 AKI. Methods:Observational study of patients requiring KRT admitted to Bellevue Hospital during the COVID surge. Bellevue Hospital is one of the largest public hospitals in the United States, providing medical care to an underserved population. There were substantial staff, supplies, and equipment shortages. Adult patients admitted with AKI who required KRT were considered for PD. We rapidly established an acute PD program. A surgery team placed catheters at the bedside in the intensive care unit; a nephrology team delivered treatment. We provided an alternative to hemodialysis and continuous venovenous hemofiltration for treating patients in the intensive-care unit, demonstrating efficacy with outcomes comparable to standard care. Results:From April 8, 2020 to May 8, 2020, 39 catheters were placed into ten women and 29 men. By June 10, 39% of the patients started on PD recovered kidney function (average ages 56 years for men and 59.5 years for women); men and women who expired were an average 71.8 and 66.2 years old. No episodes of peritonitis were observed; there were nine incidents of minor leaking. Some patients were treated while ventilated in the prone position. Conclusions:Demand compelled us to utilize acute PD during the COVID-19 pandemic. Our experience is one of the largest recently reported in the United States of which we are aware. Acute PD provided lifesaving care to acutely ill patients when expanding current resources was impossible. Our experience may help other programs to avoid rationing dialysis treatments in health crises.

We aimed to assess the efficacy and safety of canagliflozin in patients with type 2 diabetes and nephropathy according to prior history of heart failure in the Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation (CREDENCE) trial. We found that participants with a prior history of heart failure at baseline (15%) were more likely to be older, female, white, have a history of atherosclerotic cardiovascular disease, and use diuretics and beta blockers (all P < .001), and that, compared with placebo, canagliflozin safely reduced renal and cardiovascular events with consistent effects in patients with and without a prior history of heart failure (all efficacy P interaction >.150). These results support the efficacy and safety of canagliflozin in patients with type 2 diabetes and nephropathy regardless of prior history of heart failure.

BACKGROUND:The association between early changes in albuminuria and kidney and cardiovascular events is primarily based on trials of renin-angiotensin system blockade. It is unclear whether this association occurs with sodium-glucose cotransporter 2 inhibition. METHODS:analysis assessed canagliflozin's effect on albuminuria and how early change in albuminuria (baseline to week 26) is associated with the primary kidney outcome (ESKD, doubling of serum creatinine, or kidney death), major adverse cardiovascular events, and hospitalization for heart failure or cardiovascular death. RESULTS:<0.001). Residual albuminuria levels at week 26 remained a strong independent risk factor for kidney and cardiovascular events, overall and in each treatment arm. CONCLUSIONS:In people with type 2 diabetes and CKD, use of canagliflozin results in early, sustained reductions in albuminuria, which were independently associated with long-term kidney and cardiovascular outcomes.

Background: SGLT2 inhibitors have been shown to reduce hospitalization for heart failure (HHF). We sought to determine independent baseline predictors for HHF specifically in a population with type 2 diabetes and chronic kidney disease (CKD).
Method(s): CREDENCE randomized 4401 participants with type 2 diabetes and CKD to canagliflozin 100 mg versus placebo. We evaluated the baseline clinical and demographic factors using multivariate regression modeling to identify the independent predictors of HHF.
Result(s): Overall, 230 participants (89 canagliflozin; 141 placebo) had at least 1 HHF event. Canagliflozin reduced the incidence of HHF compared with placebo (4.0% vs 6.4%; HR 0.61; 95% CI 0.47-0.80). Participants with HHF events postrandomization were older (65.8 vs 62.9 y), and had a longer duration of diabetes (17.4 vs 15.7 y), higher prevalence of prior HF (30.4% vs 14.0%), higher urinary albumin:creatinine ratio (1347 vs 904 mg/g), lower estimated glomerular filtration rate (51.5 vs 56.4 mL/min/1.73m²), and higher prevalence of prior cardiovascular disease (65.7% vs 49.6%) compared to those without HHF. Independent predictors of HHF are shown in the Table.
Conclusion(s): HHF is common in patients with type 2 diabetes and CKD. Canagliflozin reduces HHF by 39% compared with placebo. Higher urinary albumin:creatinine ratio was the most potent predictor of HHF and should be part of patient risk assessment. (Table Presented)

OBJECTIVES:To estimate the incidence, risk factors, and outcomes associated with in-hospital cardiac arrest and cardiopulmonary resuscitation in critically ill adults with coronavirus disease 2019 (covid-19). DESIGN:Multicenter cohort study. SETTING:Intensive care units at 68 geographically diverse hospitals across the United States. PARTICIPANTS:Critically ill adults (age ≥18 years) with laboratory confirmed covid-19. MAIN OUTCOME MEASURES:In-hospital cardiac arrest within 14 days of admission to an intensive care unit and in-hospital mortality. RESULTS:67 (14) years). The most common rhythms at the time of cardiopulmonary resuscitation were pulseless electrical activity (49.8%, 199/400) and asystole (23.8%, 95/400). 48 of the 400 patients (12.0%) who received cardiopulmonary resuscitation survived to hospital discharge, and only 7.0% (28/400) survived to hospital discharge with normal or mildly impaired neurological status. Survival to hospital discharge differed by age, with 21.2% (11/52) of patients younger than 45 years surviving compared with 2.9% (1/34) of those aged 80 or older. CONCLUSIONS:Cardiac arrest is common in critically ill patients with covid-19 and is associated with poor survival, particularly among older patients.

PURPOSE OF REVIEW/OBJECTIVE:Direct oral anticoagulants (DOACs) are variably eliminated by the kidneys rendering their use potentially problematic in patients with chronic kidney disease (CKD) or necessitating appropriate dose adjustment. RECENT FINDINGS/RESULTS:Both observational and limited randomized trial data for DOACs compared with no treatment or with warfarin for patients with atrial fibrillation on maintenance dialysis were recently published. In a randomized trial in patients on hemodialysis, there was no significant difference in vascular calcification between patients who received rivaroxaban with or without vitamin K2 or vitamin K antagonists. A randomized trial of apixaban versus warfarin was terminated owing to poor enrollment and preliminary results identified no difference in clinical outcomes between groups. However, valuable pharmacodynamic data will be forthcoming from that trial. In observational research, among patients newly diagnosed with atrial fibrillation, there were opposing trends in the associations of apixaban initiation versus no oral anticoagulation with ischemic versus hemorrhagic stroke and no association was present with the overall risk of stroke or embolism. In another study comparing apixaban with warfarin initiation, apixaban was associated with less bleeding. Regular-dose apixaban (5 mg twice daily) associated with reduced rates of ischemic stroke or systemic embolism, whereas no such association was present for those prescribed the reduced dose (2.5 mg twice daily). SUMMARY/CONCLUSIONS:DOACs may be used after appropriate dose adjustment for an established clinical indication in patients with advanced CKD. Quality evidence for oral anticoagulation, with any specific agent or dose, for stroke prevention in hemodialysis continues to be lacking.
