A nationwide cohort study comparing the effectiveness of diuretics and calcium channel blockers on top of renin-angiotensin system inhibitors on chronic kidney disease progression and mortality.
It is unknown whether initiating diuretics on top of renin-angiotensin system inhibitors (RASi) is superior to alternative antihypertensive agents such as calcium channel blockers (CCBs) in patients with chronic kidney disease (CKD). For this purpose, we emulated a target trial in the Swedish Renal Registry 2007-2022 that included nephrologist-referred patients with moderate-advanced CKD and treated with RASi, who initiated diuretics or CCB. Using propensity score-weighted cause-specific Cox regression, we compared risks of major adverse kidney events (MAKE; composite of kidney replacement therapy [KRT], experiencing over ...

Apixaban for stroke prevention in hemodialysis patients with non-valvular atrial fibrillation
Atrial fibrillation (AF) is a common arrhythmia among patients with kidney failure on maintenance hemodialysis (HD) and is associated with a high incidence of all-cause mortality and stroke in this population.1

Aspirin (ASA) has been postulated to improve cardiovascular outcomes in at-risk individuals, although the extent of protection remains controversial. The effect of ASA on cardiovascular outcomes in patients with chronic kidney disease (CKD) was examined in The International Polycap Study-3 (TIPS-3). Patients were treated with low-dose ASA (75 mg/d) or placebo and stratified by estimated glomerular filtration rate (eGFR). The investigators looked at a composite outcome of nonfatal myocardial infarction, nonfatal stroke, and cardiac death.

Should we liberalize potassium intake in CKD? No, we should not
Although a high dietary sodium (Na) intake has dominated our understanding of pathophysiology of hypertension, the moderating effects of a dietary potassium (K) intake on blood pressure (BP) are less appreciated. K depletion in normotensive men can increase BP,1 supplementation of K among normotensive women can modestly lower 24-hour ambulatory BP,2 and in those with untreated hypertension3 or among those with hypertension and hypokalemia provoked by diuretics, K supplementation can lower BP.4 A cluster randomized trial from 600 villages in China in people with a history of previous stroke (72.6%) or a history of hypertens...

A population cohort analysis of English transplant centers indicates major adverse cardiovascular events after kidney transplantation.
Major adverse cardiovascular event (MACE) rates immediately after kidney transplantation remain uncertain due to heterogeneous reporting in the literature. To clarify this, we retrospectively studied every eligible kidney transplant procedure performed in England between April 1, 2002 and March 31. 2018 with follow-up through August 31, 2019. The primary outcome of interest was MACE broadly defined as any hospital admission with myocardial infarction, stroke, unstable angina, heart failure, any coronary revascularisation procedure and/or any cardiovascular death.

Defective KIM-1 phagocytosis does not predispose to acute graft dysfunction after kidney transplantation in humans
Introduction: Ischemia reperfusion injury (IRI) is common to several pathologic conditions, including myocardial infarction, stroke, acute kidney injury, and delayed graft function after kidney transplantation1. Clearance of apoptotic and necrotic cells by resident immune or epithelial cellsS1,S2 prevents release of harmful intracellular pro-inflammatory mediators, and is thought to represent an important mechanism to dampen secondary tissue damage and promote repair after acute injury including IRI2, 3, S3, S4.

Catastrophic kidney infarction
A 62-year-old man with a history of stroke, ischemic cardiomyopathy, and paroxysmal atrial fibrillation not on anticoagulation presented with left lower extremity weakness and numbness and was found to have left lower extremity ischemia on examination. There was also evidence of acute kidney injury with a serum creatinine level of 2.1 mg/dl from 0.8 mg/dl at baseline. A computed tomography angiogram of the abdomen and pelvis with distal runoff revealed the occlusion of the left common femoral artery and right saphenofemoral artery.

Anticoagulation in patients with kidney failure on dialysis: factor XI as a therapeutic target
Chronic kidney disease (CKD) is present in almost 10% of the world population and is associated with excess mortality and morbidity. Reduced glomerular filtration rate and the presence and extent of proteinuria, key domains of CKD, have both been shown to be strong and independent risk factors for cardiovascular disease. Patients with kidney failure requiring dialysis are at highest risk for cardiovascular events, for example, stroke or myocardial infarction, and of developing chronic cardiovascular conditions, such as heart failure.

Targeting TMEM16A-encoded Ca2+-activated Cl − channels: a new paradigm for antihypertensive therapy?
Hypertension is the leading risk factor for the development of heart diseases and stroke. Many hypertensive patients experience undesirable side effects to conventional antihypertensive pharmacotherapy. Cil et al. documented the antihypertensive profile of a novel molecule, TMinh-23 (2-bromodifluoroacetylamino-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylic acid o-tolylamide), in the spontaneously hypertensive rat model of systemic hypertension. They showed that this agent reduces blood pressu re by inhibiting transmembrane member 16A–encoded calcium-activated chloride channels in vascular myocytes from resistance arteries.

Tubuloreticular inclusions in COVID-19-related collapsing glomerulopathy
A 79-year-old male of African ancestry, with a history of hemorrhagic stroke, monoclonal gammopathy of unknown significance and chronic kidney disease stage 3 due to hypertension was admitted to Bichat hospital on day 1 after the first symptom of COVID-19 (fever). SARS-CoV 2 PCR was positive on nasal swab. At admission urinary dipstick was normal and plasma creatinine was 224 μmol/L. On day 4 plasma albumin was at 29 g/L and proteinuria was 11.4 g per gram of urinary creatinine (80% of albumin).

Prevention and treatment of stroke in patients with chronic kidney disease: an overview of evidence and current guidelines
Chronic Kidney Disease (CKD) is strongly associated with an increased risk of stroke, small vessel disease, and vascular dementia. Common vascular factors for stroke, such as hypertension, diabetes, and atrial fibrillation, are more prevalent in CKD patients, accounting for this association. However, factors unique to these patients, such as uraemia, oxidative stress, mineral and bone abnormalities, as well as dialysis-related factors are also believed to contribute to risk. Despite improvements in stroke treatment and survival in the general population, the rate of improvement in patients with CKD, especially those who ar...
