Peritoneal ultrafiltration in refractory heart failure: a cohort study.

Introduction: Acutely decompensated heart failure (HF) in patients with diuretic resistance is often treated with extracorporeal ultrafiltration. Peritoneal ultrafiltration (PUF) has been proposed for the long-term management of severe HF after resolution of the acute episode. The aim of the present study was to evaluate the use of PUF in the treatment of chronic refractory HF in patients without end-stage renal disease.

COL4A3/COL4A4 mutations: from familial hematuria to autosomal-dominant or recessive Alport syndrome.

Unlabelled: COL4A3/COL4A4 mutations: From familial hematuria to autosomal-dominant or recessive Alport syndrome.

Background: Mutations of the type IV collagen COL4A5 gene cause X-linked Alport syndrome (ATS). Mutations of COL4A3 and COL4A4 have been reported both in autosomal-recessive and autosomal-dominant ATS, as well as in benign familial hematuria (BFH).
