Objectives: The aim of this study was to determine the prevalence of bile cast nephropathy (BCN) in autopsied cirrhotic patients and to correlate BCN with clinical and laboratory data to direct attention to this underrecognized renal complication of liver failure. Methods: We assessed 114 autopsy cases of cirrhosis for the presence of renal intratubular bile casts using Hall stain for bile. Presence of bile casts was correlated with etiology of cirrhosis, clinical and laboratory data, and histologic findings...

Light chain deposition disease (LCDD) is characterized by monotypic immunoglobulin depositions which will eventually lead to loss of organ function if left untreated. While the kidney is almost always affected, the presence and degree of LCDD in other organs vary. Ten to 30% of LCDD patients have underlying Multiple Myeloma (MM), yet outcome and prognostic markers in this particular patient group are still lacking. Here, we analyzed 69 patients with MM and biopsy proven LCDD and report on renal and extra-renal involvement and its impact on prognosis as well as renal response depending on hematologic response...

Over the past four years, all patients with unexplained rapid progression of their renal disease were subjected to kidney biopsy, despite their small size (<9 cm), to define its etiology. Children, pregnant women, morbidly obese patients, and those with an unstable cardiovascular state, septicemia, bleeding diathesis as well as those kidney size with size <6 cm were excluded from the study. Doppler ultrasound was used to exclude renovascular/ischemic nephropathy. The procedure was performed by an interventional radiologist using a biopsy gun technique and under ultrasound guidance...

Anticoagulant-related nephropathy is a type of acute kidney injury caused by overcoagulation. We describe a case of an 84-year-old man with arterial hypertension, coronary heart disease and atrial fibrillation treated with acenocoumarol, who presented with haematoproteinuria and acute kidney injury during a phase of excessive anticoagulation. In addition to IgA nephropathy, renal biopsy also revealed acute tubular necrosis, red blood cell casts and positive iron staining in tubular cells. After this acute episode, renal function improved and proteinuria decreased below the nephrotic range...

Warfarin is an oral anticoagulant used extensively in clinical practice; However, its side-effect of causing renal damage has been recently detected. The mechanism leading to renal damage is glomerular hemorrhage and red blood cell tubular casts prothrombin time. Recently, it was found that warfarin causes renal damage in patients with chronic kidney disease and is also associated with progression of renal disease. Warfarin causing acute kidney injury in patients with normal renal function is a rare manifestation...

Treatment with oral anticoagulants has been associated with worsening kidney function in patients with chronic kidney disease (CKD) as well as among patients without underlying CKD. Thus, anticoagulant-related nephropathy (ARN) is an increasingly recognized entity nowadays, mainly associated with warfarin anticoagulation. Recent evidence indicates that patients treated with the direct anticoagulants may also be at risk of ARN. However, the true incidence of anticoagulant-related nephropathy is difficult to determine...

INTRODUCTION: High cut-off dialysis, increasingly used in multiple myeloma patients, is susceptible to influence anticancer drug elimination. We report about lenalidomide disposition in a patient on high cut-off dialysis for renal failure secondary to myeloma cast nephropathy. METHODS: The patient received a higher dosage of lenalidomide (5 mg b.i.d.), owing to concerns about a potential decrease in lenalidomide exposure during dialysis sessions. A set of blood samples was taken in order to develop a pharmacokinetic model accounting for lenalidomide concentrations in this setting...

A 14-year-old girl was treated for 3 days with tosufloxacin (450 mg twice a day) for acute bronchitis and then developed acute kidney injury. Renal ultrasound showed enlarged kidneys without hydronephrosis. Urinalysis indicated drug crystal casts (2-3/HPF), consistent with drug-induced crystalline nephropathy. The patient recovered gradually with i.v. hydration and discontinuation of tosufloxacin, leading to the diagnosis of tosufloxacin crystalline nephropathy. Medical practitioners should be aware that crystalline nephropathy can occur in pediatric patients receiving tosufloxacin...

Acute kidney injury (AKI) is a major complication in patients with liver disease. Although hepatorenal syndrome is frequently involved, bile cast nephropathy, characterized by tubular bile cast formation, has been scarcely described in the setting of severe liver failure. Few renal histology studies are available in these patients. We describe a case of bile cast nephropathy in a patient with obstructive cholestasis caused by stones in the common bile duct. The kidney biopsy confirmed this diagnosis, with several green casts in tubular lumens, tubular injury, and bilirubin composition of the tubular casts with Hall stain...

Acute kidney injury (AKI) is a frequent complication of multiple myeloma and is associated with increased short-term mortality. Additionally, even a single episode of AKI can eventually lead to end-stage renal disease (ESRD), significantly reducing quality of life and long-term survival. In the setting of multiple myeloma, severe AKI (requiring dialysis) is typically secondary to cast nephropathy (CN). Renal injury in CN is due to intratubular obstruction from precipitation of monoclonal serum free light chains (sFLC) as well as direct tubular toxicity of sFLC via stimulation of nuclear factor (NF)κB inflammatory pathways...

History and admission findings: We report on a 76-year-old man presenting with painless jaundice who developed dialysis-dependent acute kidney injury. Investigations: Biliary tract was examined with endoscopy, in addition kidney biopsy was performed. Diagnosis, treatment and course: A stenosing process could be seen in the biliary tract, leading to stent implantation. However, jaundice did not resolve. Kidney biopsy revealed bile casts indicating cholemic nephropathy. After switch of concomitant medication, hyperbilirubinemia resolved and kidney function was completely restored...

HIV-1 transgenic mice on the FVB/NJ background (TgFVB) represent a validated model of HIV-associated nephropathy (HIVAN). A major susceptibility locus, HIVAN1, was previously mapped to chromosome 3A1-A3 in a cross between TgFVB and CAST/EiJ (CAST) strains, and introgression of a 51.9 Mb segment encompassing HIVAN1 from CAST into TgFVB resulted in accelerated development of nephropathy. We generated three sub-congenic strains carrying CAST alleles in the proximal or distal regions of the HIVAN1 locus (Sub-II, 3...

Renal impairment (RI) is one of the most common complication of multiple myeloma (MM). RI is present in almost 20% of MM patients at diagnosis and in 40%-50% of patients during the course of their disease. Areas covered: Biology along with tools for diagnosis and management of RI are reported in this paper. Papers published in PubMed and reported abstracts up to May 2016 were used. Expert opinion: Moderate and severe RI increases the risk of early death; thus rapid intervention and initiation of anti-myeloma treatment is essential and improves renal outcomes in RI patients...

BACKGROUND: Renal impairment (RI) is a common complication of multiple myeloma (MM). Around 50% of patients with MM have RI at presentation, and up to 5% require dialysis treatment. Severe acute kidney injury (AKI) as a cause of RI is a particular challenge as historically the survival of patients who sustain this complication and require dialysis is very poor. However, in this current period, survival is improving and the focus is on optimum use of novel chemotherapies and the evaluation of extra-corporeal therapies for removal of serum immunoglobulin light chains...

BACKGROUND: Multiple myeloma (MM) is a clonal B-cell malignancy of the bone marrow. Renal impairment is a common complication of MM. So far, there is no systematic overview of MM-induced kidney disease in China. SUMMARY: The incidence of MM is 0.6/100,000 in China. Twenty-four, 19.7, and 30.8% of all patients with MM had renal insufficiency [defined by serum creatinine (Scr) ≥2 mg/dl] at diagnosis in China mainland, Hong Kong and Taiwan, respectively. Novel criteria based on the estimated glomerular filtration rate measurements are recommended for the assessment of renal function in patients with MM with stabilized Scr...

Nearly 50% of patients with multiple myeloma develop renal disease, most commonly from AKI caused by cast nephropathy. Development of AKI is associated with poor 1-year survival and reduces the therapeutic options available to patients. There is a great need for more effective therapies. Cast nephropathy is caused by the interaction and aggregation of filtered free light chains and Tamm-Horsfall protein causing intratubular obstruction and damage. The key to treating cast nephropathy is rapid lowering of free light chains, because this correlates with renal recovery...

Disorders of plasma and B cells leading to paraproteinemias are associated with a variety of renal diseases. Understanding the mechanisms of injury and associated nephropathies provides a framework that aids clinicians in prompt diagnosis and appropriate adjunctive treatment of these disorders. Glomerular diseases that may be associated with paraproteinemias include amyloid deposition, monoclonal Ig deposition disease, proliferative GN with monoclonal Ig deposits, C3 glomerulopathy caused by alterations in the complement pathway, immunotactoid glomerulopathy, fibrillary GN, and cryoglobulinemia...
