"Results of large surface hemodialysis (LSH): a shorter and cheaper treatment".

A surface area of 5 m2, a QB of 500 ml/min and a QD of 1000 ml/min reduces the time of hemodialysis to just 6 hours per week. All the patients had been in a conventional dialysis program for at least 2 years. These patients have now been in LSH for a period of between 2 and 3 years. Most patients have no appreciable residual function, they follow a free diet, living a normal life, and weigh between 51 and 88 Kg, ranging in ages from between 26 and 69 years. We use this technique with 3 schedules: Schedule I) 2 hours/3 days/week; Schedule II) 3 hours/2 days/week; Schedule III) 6 hours/1 day/week. In the 3 schedules the clinical and biochemical results have been the same as with conventional dialysis. With this technique the patients have greater freedom and comfort because they avoid 312 hours per year connected to the artificial kidney. The patients in Schedule II also avoid 52 dialysis sessions and 104 trips to the dialysis center per year. And the patients in Schedule III also avoid 104 dialysis sessions and 208 trips to the center per year. Furthermore, the cost savings in Schedule II is $2,500 per year/patient and in Schedule III $8,500 per patient/year.

High-density lipoproteins in untreated idiopathic nephrotic syndrome without renal failure.

Serum apoprotein A-I and lipid composition of high-density lipoproteins in 14 adults and 9 children with idiopathic untreated nephrotic syndrome without renal failure were studied. Serum apoprotein A-I in adults was significantly raised compared to a control group (1.72 +/- 0.49 and 1.45 +/- 0.15 g/l, Mean +/- SD, respectively); a similar trend was observed in children (1.88 +/- 0.62 and 1.52 +/- 0.21 g/l, respectively). High-density lipoprotein cholesterol was normal in both groups of patients (1.19 +/- 0.30 and 1.50 +/- 0.48 mmol/l in adults and in children, respectively), whereas high-density lipoprotein phospholipids were decreased in adults and increased in children. In addition, apoprotein A-I: high-density lipoprotein cholesterol ratios in both groups of patients were significantly increased with respect to their control groups. These alterations suggest the existence of qualitative changes in high-density lipoprotein composition. Despite other associated risk factors, and particularly from the point of view of the 'high-density lipoprotein hypothesis', our patients with untreated nephrotic syndrome without renal failure seem not to be at a higher coronary risk.
