[Renal toxicity of antineoplasic agents].

"Renal toxicity of antineoplasic agents Renal toxicity of antineoplasic agents is a common complication faced by oncologists and nephrologists whose incidence depends on therapeutic classes used and patient's comorbidities. Nephrotoxicity is variable, according to mecanisms, chronology and potential reversibility. Besides acute kidney injury and/or chronic kidney disease, clinical features include several urinary abnormalities (mainly proteinuria).

A new expression of immune checkpoint inhibitors' renal toxicity: when distal tubular acidosis precedes creatinine elevation.

The main manifestation of acute interstitial nephritis (AIN) due to immune checkpoint inhibitors is acute kidney injury. We report here a biopsy-proven AIN revealed by tubular acidosis. This case highlights that immune checkpoint inhibitor prescribers must be aware of electrolytic disorders since tubular dysfunction can precede serum creatinine increase and reveal renal toxicity.

Acute Renal Colic Due to Immunoglobulin Free Light Chain Kidney Stones: A Case Report of an Unusual Complication of Multiple Myeloma.

Kidney failure is common in patients with a monoclonal gammopathy, most frequently due to hypercalcemia or myeloma cast nephropathy. Immunoglobulin crystallization is an uncommon phenomenon that also results in kidney injury. We report the case of a 74-year-old man with recurrent renal colic and acute kidney injury.

Severe tubulointerstitial nephritis: tracking tuberculosis even in the absence of renal granuloma.

Extra-pulmonary tuberculosis is frequently located in the kidneys and, in such cases, could be associated with a granulomatous interstitial nephritis. Granulomas are not always detected, especially in human immunodeficiency virus (HIV)-positive patients. We report here a case of tubulointerstitial nephritis without granulomas in an HIV-negative patient.

Opening an onconephrology clinic: recommendations and basic requirements.

Onconephrology is a rapidly evolving subspeciality that covers all areas of renal involvement in cancer patients. The complexity of the field may benefit from well-defined multidisciplinary management administered by a dedicated team. Since there is an increasing need to address the needs of this population in dedicated outpatient clinics, it is critical to highlight basic characteristics and to suggest areas of development.

Adjunction of a MEK inhibitor to Vemurafenib in the treatment of metastatic melanoma results in a 60% reduction of acute kidney injury.

Introduction: A combined therapy MEK inhibitor, Cobimetinib (CB) and BRAF inhibitor, Vemurafenib (VMF), results in an improvement in progression-free survival among patients with BRAF V600-mutated metastatic melanoma. VMF skin adverse effects attributed to ERK paradoxical activation are decreased by the adjunction of CB. The aim of this study was to determine if this combination also improved the renal side effects of VMF.

New insights into renal toxicity of the B-RAF inhibitor, vemurafenib, in patients with metastatic melanoma.

Purpose: Vemurafenib (VMF) is a B-RAF inhibitor used in the treatment of B-RAF-V600-mutant metastatic melanomas. Reports of acute kidney injury (AKI) in patients treated with VMF are scarce.

Methods: To investigate the incidence and severity of AKI, we conducted a retrospective, observational, monocentric study in the Lyon Sud Hospital University, France, which included 74 patients with metastatic B-RAF-mutated melanomas treated with VMF, between June 2011 and August 2014.

In Hemodialysis Patients, Intradialytic Resistance Exercise Improves Osteoblast Function: A Pilot Study.

Objective: Abnormalities in mineral and bone metabolism are frequent in chronic kidney disease patients. Physical exercise can improve many indicators of physical functioning, and recent studies showed beneficial effects on bone mineral density in the general population. The aim of this study was to evaluate the effects of resistance exercise training on bone markers and body composition in hemodialysis (HD) patients.
