In search of potential predictors of erythropoiesis-stimulating agents (ESAs) hyporesponsiveness: a population-based study.

Background: Evidences show that around 20% of biosimilar or originator erythropoiesis-stimulating agents (ESAs) users are hyporesponsive. Controversial post-marketing data exist on the predictors of ESA hyporesponsiveness. The aim of this study was to identify predictors of ESA hyporesponsiveness in patients with chronic kidney disease (CKD) or cancer in clinical practice.

The Myth of Water and Salt: From Aquaretics to Tenapanor.

The impact of water intake has been studied in several renal diseases. For example, increasing water intake is useful to prevent primary and secondary nephrolithiasis. In autosomal dominant polycystic kidney disease, arginine vasopressin (AVP) is involved in the progression of the disease, and water intake could play a therapeutic role by inhibiting the synthesis of AVP, but its efficacy is still controversial.

Novel avenues for treating diabetic nephropathy: new investigational drugs.

At present, treatment of diabetic kidney disease (DKD) is still mainly based on drugs acting on glycemic and blood pressure control, as there is no validated therapy able to halt the progression of renal failure. Because of the high incidence of DKD, due to the increase of diabetes mellitus in general population, new therapeutic strategies are needed. Areas covered: We analysed ongoing and already completed clinical trials, from clinicaltrials.

Pruritus and quality of life in renal transplant patients.

Background: Pruritus has a negative impact on quality of life (QoL) in dialysis patients. The reversibility of this symptom after renal transplantation and its impact upon QoL has scarcely been studied in these patients.

Methods: Pruritus was evaluated by the Visual Analogue Scale (VAS), the Visual Rating Scale (VRS), and the Numerical Rating Scale (NRS) in 133 unselected renal transplant patients, 62 healthy subjects, and 29 hemodialysis patients.

Renal biopsy: Still a landmark for the nephrologist.

Renal biopsy was performed for the first time more than one century ago, but its clinical use was routinely introduced in the 1950s. It is still an essential tool for diagnosis and choice of treatment of several primary or secondary kidney diseases. Moreover, it may help to know the expected time of end stage renal disease.

Role of Vitamin D in Vascular Complications and Vascular Access Outcome in Patients with Chronic Kidney Disease.

Vitamin D has been known for a long time as a major factor involved in the calcium- phosphate balance and homeostasis, along with parathyroid hormone (PTH). While vitamin D effects on calcium and phosphate are fully known, recent studies attempted to link vitamin D status and cardiovascular diseases. The involvement of vitamin D on vascular remodeling is mediated by several mechanisms such as activation of renin-angiotensin-aldosterone system (RAAS), cell proliferation and anti-apoptotic cell pathways.

The Management of Diabetes Mellitus in Patients with Chronic Kidney Disease: A Population-Based Study in Southern Italy.

Background And Objectives: Diabetes mellitus in patients with chronic kidney disease (CKD) is known as diabetic kidney disease (DKD). Pharmacological management of DKD is challenging due to reduced renal excretion of some antidiabetic drugs. The aim of this population-based study was to explore antidiabetic drug use in DKD patients from Southern Italy.

[Periorbital purpura: a pathognomonic but late sign of AL amyloidosis].

Introduction: AL amyloidosis is the most common type of systemic amyloidosis and is caused by the deposition of an amyloidogenic protein composed of immunoglobulin light chains produced by a clonal population of plasma cells.

Case Report: We report the case of a 77-year-old woman with arterial hypotension, peripheral edema and renal failure. Electrocardiogram reveals low voltage on peripheral leads.

Nephro-oncology: a link in evolution.

A multidisciplinary approach represents the best method to interact with patients. Neoplastic and renal diseases are closely related to each other because of an increased risk of cancer among individuals with end-stage renal disease and because of the high prevalence of renal failure in cancer patients. Physicians should be able to know how to prevent and treat the possible complications which may appear during the course of neoplastic disease that may lead to kidney damage such as the Acute Tumor Lysis Syndrome, disorders of hydroelectrolitic balance, metabolic alterations in the calcium-phosphorus, anemia, interstitial and glomerular impairment due to chemotherapy.
