A tale of 100 kidney stones

Materiale supplpementare. Crohn’s disease with diarrhea predisposes to calcium oxalate stones primarily because of enteric hyperoxaluria from fat malabsorption and saponification resulting in usage of calcium and less formation of insoluble calcium oxalate salts in the intestinal lumen.

A tale of 100 kidney stones

Crohn’s disease with diarrhea predisposes to calcium oxalate stones primarily because of enteric hyperoxaluria from fat malabsorption and saponification resulting in usage of calcium and less formation of insoluble calcium oxalate salts in the intestinal lumen. There is thus increased gastrointestinal oxalate absorption leading to increased urinary oxalate excretion. Other factors include increased oxalate colonic mucosa permeability and gastrointestinal tract decolonization of the … Leggi tutto

Primary and secondary hyperoxaluria: Understanding the enigma

Hyperoxaluria is characterized by an increased urinary excretion of oxalate. Primary and secondary hyperoxaluria are two distinct clinical expressions of hyperoxaluria. Primary hyperoxaluria is an inherited error of metabolism due to defective enzyme activity. In contrast, secondary hyperoxaluria is caused by increased dietary ingestion of oxalate, precursors of oxalate or alteration in intestinal microflora. Clinical … Leggi tutto

Secondary Oxalate Nephropathy: A Systematic Review

Little is known of the clinical outcomes of secondary oxalate nephropathy. To inform clinical practice, we performed a systematic review of case reports and case series to examine the clinical characteristics and outcomes of patients with secondary oxalate nephropathy. Secondary oxalate nephropathy is a rare but potentially devastating condition. Renal replacement therapy is required in … Leggi tutto

Risk Factors for Kidney Stone Formation following Bariatric Surgery

Kidney stones are painful, common, and increasing in incidence. Obesity and bariatric surgery rates are also on the rise in the United States. Although bariatric surgery is associated with improvements in metabolic outcomes, malabsorptive bariatric surgery procedures are also associated with increased risk of kidney stones. Restrictive bariatric surgeries have not been associated with kidney-stone … Leggi tutto

A Prospective, Double-Blind, Randomized, Placebo-Controlled, Crossover Study Using an Orally Administered Oxalate Decarboxylase (OxDC)

Hyperoxaluria is typically associated with excessive oxalate intake in the diet, decreased dietary calcium, hyperabsorption of oxalate, or increased endogenous production of oxalate. The disorder spectrum extends from recurrent kidney stones to ESKD. This clinical trial sought to evaluate the effectiveness of an acid stable oxalate decarboxylase (OxDC) to reduce urinary oxalate in healthy subjects … Leggi tutto

Oxalate Nephropathy Associated with Chronic Pancreatitis

Enteric overabsorption of oxalate may lead to hyperoxaluria and subsequent acute oxalate nephritis (AON). AON related to chronic pancreatitis is a rare and poorly described condition precluding early recognition and treatment. AON is an under-recognized severe crystal-induced renal disease with features of tubulointerstitial nephritis that may occur in patients with a long history of chronic … Leggi tutto
