Coronary calcification in hemodialysis patients: the contribution of traditional and uremia-related risk factors.

Background: Coronary artery calcification is a common feature of atherosclerosis, occurring in 90% of angiographically significant lesions. There is recent evidence that coronary artery calcification is frequent in hemodialysis patients and it has been suggested that this increased incidence may be associated to uremia-related factors. The development and progression of coronary artery calcification is similar to osteogenesis.

Clinical evaluation of a peritoneal dialysis solution with 33 mmol/L bicarbonate.

Objective: To evaluate the efficacy and safety of a new peritoneal dialysis solution with 33 mmol/L bicarbonate.

Design: In an acute, prospective, randomized cross-over study, 8 patients were randomized in two groups of 4. On the first study day, the first group performed two consecutive 4-hour exchanges with a dialysis solution containing 35 mmol/L lactate: the first exchange with 13.

Clinical evaluation of an optimized 1.1% amino-acid solution for peritoneal dialysis.

A significant percentage of dialysed patients have inadequate protein intake. One strategy for treating the protein malnutrition in peritoneal dialysis patients is to replace glucose in the dialysis solution by amino acids. A new peritoneal dialysis solution containing 1.

[Late revascularization of the renal artery: what are the prognostic criteria?].

Two patients with non functioning silent kidney on excretory urography and renal artery occlusion on angiography, underwent renal artery revascularization without severe hypertension or renal failure. Angiographic appearance of collateral circulation, histologic evidence of intact viable glomeruli and a normal sized kidney are necessary for successful results. Renal blood flow was restored in the two patients but one had slight return of function and the other patient showed no evidence of improvement.

Haemodialysis of pyrazinamide in uraemic patients.

The pharmacokinetics of PZA during haemodialysis were determined in 6 patients with chronic renal impairment after a single oral dose of 25.7 (1.9) mg.

[5 years of continuous ambulatory peritoneal dialysis (CAPD) (multicenter study of 345 patients)].

A retrospective survey has been undertaken in 7 different centers: 345 patients trained to CAPD between 1978 and 1983 were studied: technic success and survival rate were analysed using actuarial methods. Drop-out has dramatically decreased after May 1981 due to a lower mortality whatever the age. For all patients the actuarial survival at two years after 1981 is 87.
