Renal Volume in ADPKD Patient Evaluation.

The clinical manifestations of ADPKD are related to the growth of renal cysts. Renal volume has been recognised as the biomarker that is able to identify those patients at risk of complications (hypertension and haematuria) and at risk of progression to End Stage Renal Disease (ESRD). Recently, several scores have been introduced to predict the evolution of ADPKD.

[ADPKD treatment: Tolvaptan and Octreotide].

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most frequent monogenic hereditary disease as well as the most studied inherited kidney disease. Two drugs have recently been authorized that can slow down the progression of the disease: Tolvaptan (vasopressin receptor antagonist) and Octreotide-LAR (long-acting somatostatin analogue); they both are able to reduce the activity of cyclic adenosine monophosphate (cAMP) and therefore have anti-proliferative and anti-secretory effects. This review analyzes the main trials published to date demonstrating the effects on disease progression in patients with ADPKD and illustrates the indications for identifying subjects eligible for therapy.

[Renal manifestation of Autosomal Dominant Polycystic Kidney Disease].

Autosomal dominant polycystic kidney disease affects over 12 million people in the world and is the fourth cause of ESRD. It is the main monogenic kidney disease and causes the progressive formation of cysts leading to renal failure after a few decades. The main manifestations of the disease are observed even at a young age.

Nonvitamin K-dependent oral anticoagulants (NOACs) in chronic kidney disease patients with atrial fibrillation.

Atrial fibrillation (AF) represents the most common arrhythmia in patients with chronic kidney disease (CKD). As in the general population, in CKD patients AF is associated with an increased risk of thromboembolism and stroke. However, CKD patients, especially those on renal replacement therapy (RRT), also exhibit an increased risk of bleeding, especially from the gastrointestinal tract.

Continuous veno-venous hemofiltration using a phosphate-containing replacement fluid in the setting of regional citrate anticoagulation.

Purpose: The need for prolonged anticoagulation and the occurrence of hypophosphatemia are well known drawbacks of continuous renal replacement therapies (CRRT). The aim was to evaluate the effects on acid-base status and serum phosphate of a regional citrate anticoagulation (RCA) protocol for continuous veno-venous hemofiltration (CVVH) combining the use of citrate with a phosphate-containing replacement fluid.

Methods: In a small cohort of heart surgery patients undergoing CRRT for acute kidney injury, we adopted an RCA-CVVH protocol based on a commercially available citrate solution (18 mmol/l) combined with a recently introduced phosphate-containing replacement fluid (HCO3 -30 mmol/l, phosphate 1.
