Cholemic or bile cast nephropathy is an under-reported entity characterized by acute renal dysfunction in patients with hepatic insult. Limited literature is available regarding its clinical presentation, pathogenesis and prognosis. We hereby present a pediatric case who presented with acute on chronic liver failure with renal dysfunction secondary to cholemic nephropathy.

Importance: Cast nephropathy is the main cause of acute kidney injury in multiple myeloma and persistent reduction in kidney function strongly affects prognosis. Strategies to rapidly remove nephrotoxic serum-free light chains combined with novel antimyeloma agents have not been evaluated prospectively. Objective: To compare the hemodialysis independence rate among patients newly diagnosed with myeloma cast nephropathy treated with hemodialysis using a high-cutoff dialyzer (with very large membrane pores and high permeability to immunoglobulin light chains) or a conventional high-flux dialyzer (with small pores and lower permeability)...

Evans syndrome (ES) is a rare autoimmune disorder whose exact pathophysiology is unknown. It is characterized by the simultaneous or subsequent development of autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). Intravascular hemolysis, with hemoglobinemia, is known to produce acute kidney injury; however, the development of intratubular hemoglobin casts (hemoglobin cast nephropathy) in the setting of acute hemolysis is uncommon. Likewise, the association of ES and acute renal failure is equally uncommon...

Acid-base regulation is essential to maintain homeostasis in humans. Carbonic acid/bicarbonate (H2CO3/HCO3(-)) couple is the most predominant extracellular buffer to keep plasma pH within a physiological range. The ability to (re)generate such a buffer is a key milestone that necessitates to understand a precise physiology of both renal tubule and digestive tract. Here, we first reviewed renal and digestive cycles of bicarbonate in physiology. We also reviewed pathological findings where acid-base disequilibrium is involved and nutritional and/or alkali therapy could be necessary...

Renal impairment (RI) is a common complication of multiple myeloma (MM), which is presented as chronic kidney disease (CKD) or acute kidney injury (AKI). The typical pathological feature is cast nephropathy. Presently international system staging (ISS) is used in evaluating MM. Although the classic Durie-Salmon staging system could be still used in clinical practice, it may miss out some patients with renal impairment. For evaluations of RI in MM patients with CKD, it's recommended to assess the estimated glomerular filtration rate (eGFR) by creatinine based formula CKD-epidemiology collaboration (EPI) or modification of diet in renal disease(MDRD) and to stage the renal injuries according to 2013 Kidney Disease Improving Global Outcomes (KDIGO) CKD guidelines...

Light chain cast nephropathy is the most common form of kidney disease in patients with multiple myeloma. Light chain casts may occasionally show amyloid staining properties, that is, green birefringence after Congo red staining. The frequency and clinical significance of this intratubular amyloid are poorly understood. Here, we retrospectively assessed the clinicopathological features of 60 patients with histologically proven light chain cast nephropathy with a specific emphasis on intratubular amyloid, especially, its association with extrarenal systemic light chain amyloidosis...

An 83-year-old Japanese man had a history of chronic heart failure due to bradycardia-tachycardia syndrome. He was admitted to our hospital because of macrohematuria and acute kidney injury (AKI), which were detected by an urologist at an outpatient visit. He had a history of recurrent macrohematuria and transurethral resection of bladder tumors twice in the preceding 2 years. He had been on warfarin for 12 years, with a stable international normalized ratio (INR) that was usually less than 2.1. Urinalysis revealed numerous red blood cells (RBCs) and mild proteinuria without RBC casts...

BACKGROUND: In patients with cast nephropathy and acute kidney injury (AKI) requiring dialysis, the reduction of serum free light chains (FLC) using chemotherapy and intensive hemodialysis (IHD) with a high cut-off filter may improve renal and patient outcomes. We evaluated the effectiveness of a combination of chemotherapy and IHD with an adsorbent polymethylmethacrylate membrane (IHD-PMMA) on renal recovery and survival. METHODS: A single-center retrospective cohort-study was conducted...

Kidney diseases affect many hospitalized patients and contribute to morbidity and mortality. Therefore, kidney disease should be prevalent, but the frequency and spectrum of medical renal pathology in autopsy specimens has not been well documented. We sought to determine the spectrum of medical renal pathology in adult autopsy specimens and the frequency of overlooked diagnoses. We reviewed the hematoxylin- and eosin-stained kidney sections from 140 adult autopsies performed at a large teaching hospital over a 2-year period...

Acute kidney injury is common in patients with liver disease and associated with significant morbidity and mortality. Besides bacterial infections, fluid loss, and use of nephrotoxic drugs AKI in liver disease may be triggered by tubular toxicity of cholephiles. Cholemic nephropathy, also known as bile cast nephropathy, supposedly represents a widely underestimated but important cause of renal dysfunction in cholestasic or advanced liver diseases with jaundice. Cholemic nephropathy describes impaired renal function along with characteristic histomorphological changes consisting of intratubular cast formation and tubular epithelial cell injury directed towards distal nephron segments...

Myeloma cast nephropathy is an obstructing disorder of renal tubules, caused by precipitation of Bence Jones proteins. Myeloma-like cast nephropathy (MLCN) has been reported in the literature to occur in various primary renal and nonrenal diseases. We present a series of three rare cases of cast nephropathy, two of which are HIV patients, and the third patient is receiving cisplatin-based chemotherapy. However, in all three patients plasma cell dyscrasia has been ruled out. A 30-year-old male was admitted to the hospital with facial cellulitis...

A 30-year-old female was symptomatic with headache, fatigue, and weakness since October 2011 and was told to have anemia. In January 2012, she was admitted outside with pulmonary edema. Investigations revealed advanced azotemia, anemia, and hypercalcemia. Urine showed 2 + proteins and 30-35 red blood cells. There was no history of oral ulcers, rash, Raynaud's phenomenon, or hemoptysis. She was evaluated for causes of rapidly progressive "renal failure." Hemolytic work-up; antinuclear antibody, double-stranded DNA, and anti-neutrophil cytoplasmic antibody were negative...
