Calciphylaxis responsive to lanthanum carbonate (FOSRENOL) therapy.

Calciphylaxis is a rare and debilitating vasculopathy predominantly seen in patients with renal failure. The proposed mechanism of injury is active vascular calcification with associated elevated parathyroid hormone, hypercalcemia, or hyperphosphatemia. With improved pharmacologic agents including non-calcium containing phosphate binders, vitamin D analogues, calcimimetics, and bisphosphonates, targeted therapy on the mineralization process has been tried with varied success.

Knowledge of phosphorus compared with other nutrients in maintenance dialysis patients.

Objective: This study's objective was to assess knowledge of phosphorus compared with other nutrients in patients undergoing maintenance dialysis (MD).

Design: We compared knowledge of phosphorus vs. other nutrients important to the MD diet (potassium, sodium, and protein) in patients undergoing hemodialysis (HD) and peritoneal dialysis (PD).

Local television news reporting of kidney disease.

Background: Local television is the primary news source for the majority of Americans. This study aims to describe how local news reports on kidney disease.

Methods: Using our searchable database of health-related late local news segments from 2002, we identified stories with the key words kidney, hypertension, blood pressure, or diabetes.

Conflicting dietary advice for adhering to low-sodium and low-phosphorus diets.

Objective: To elucidate conflicts that patients face when advised to limit multiple nutrients in their diet.

Design: We analyzed the phosphorus content of low-sodium foods compared with their regular-sodium content counterparts, and the sodium content of low-phosphorus foods compared with foods containing higher levels of phosphorus. Low-sodium and low-phosphorus foods were identified with the use of recommendations from National Kidney Foundation patient information Web sites.

Karyomegalic tubulointerstitial nephritis--a case report.

Karyomegalic tubulointerstitial nephritis is a rare disease of uncertain etiology, which leads to progressive renal failure. Here, we report on a 39-year-old patient who presented with asymptomatic progressive decline of renal function. Two sequential renal biopsies demonstrated chronic tubulointerstitial nephritis with bizarre and dramatic enlargement of proximal tubule epithelial cell nuclei - the hallmark of karyomegalic nephritis.

Evaluation of eHealth web sites for patients with chronic kidney disease.

Background: Chronic kidney disease (CKD) affects up to 19.2 million Americans, and untreated kidney disease can progress to kidney failure. Patient education is an important part of slowing disease progression, but the ability of health professionals to provide this education is limited by time constraints.
