Cognitive impairment in patients on dialysis: can we prevent it?

Chronic kidney disease (CKD) is among the leading causes of morbidity and mortality as it affects more than 10% of the global adult population. Cognitive impairment has a positive correlation with the stage of CKD. It has been recorded in more than half of CKD patients undergoing kidney replacement therapy.

Mineralocorticoid receptor antagonists in kidney transplantation.

Background: The fundamental role of the renin-angiotensin-aldosterone system in the pathophysiology of chronic kidney disease, congestive heart failure, hypertension and proteinuria is well established in pre-clinical and clinical studies. Mineralocorticoid receptor antagonists are among the primary options for renin-angiotensin-aldosterone system blockage, along with angiotensin-converting enzyme inhibitors and angiotensin receptor blockers.

Methods: In this narrative review, we aim to evaluate the efficiency and safety of mineralocorticoid receptor antagonists in kidney transplant recipients, including the potential underlying pathophysiology.

Intravenous fluid therapy in accordance with kidney injury risk: when to prescribe what volume of which solution.

Acute kidney injury (AKI) is common in hospitalized patients while common risk factors for the development of AKI include postoperative settings, patients with baseline chronic kidney disease (CKD) or congestive heart failure. Intravenous (IV) fluid therapy is a crucial component of care for prevention and treatment of AKI. In this narrative review, we update the approach to IV fluid therapy in hospitalized patients including the timing of fluid prescription, and the choice of fluid type, amount and infusion rate along with the potential adverse effects of various crystalloid and colloid solutions, addressing specifically their use in patients with acute kidney disease, CKD or heart failure, and their potential impact on the risk of hospital-acquired AKI.
