title: [Incremental approach to hemodialysis: twice a week, or once weekly hemodialysis combined with low-protein low-phosphorus diet?].
abstract: The start of dialysis treatment is a critical step in the care management of chronic renal failure patients. When hemodialysis is performed three times a week, rapid loss of kidney function and of urine volume output generally occur and this represents an unfavorable prognostic factor. Instead, reducing frequency of hemodialysis sessions, as well as peritoneal dialysis, can contribute to a lesser decrease of residual renal function. Unfortunately, the existing protocols for an incremental hemodialysis approach are not particularly common and they are generally limited to a twice a week hemodialysis schedule. In addition to clinical and economic reasons, an incremental approach to ESRD also contributes to better social and psychological adaptation by the patients to the dramatic change in living conditions linked to the maintenance dialysis treatment. In patients who have attitude for low-protein nutritional therapy, a once weekly dialysis schedule combined with low-protein, low-phosphorus, normal to high energy diet in the remaining six days of the week can be implemented in selected patients. In our experience, this kind of program produced important clinical results and reduction in costs and hospitalization. When compared with a three times a week dialysis schedule, a greater protection of residual renal function and of urine volume output, lower increase in 2 microglobulin, better control of phosphorus and less consumption of phosphate binders and erythropoietin were observed. Careful clinical monitoring and nutrition is essential for the safety and optimization of infrequent hemodialysis. Long-term follow-up analysis shows favorable effects on the overall survival. Furthermore, twice a week hemodialysis is not the only option for an incremental approach of dialysis commencing. In patients who have a good attitude for low-protein nutritional therapy, its arrangement with a program of once weekly dialysis represents a real and effective alternative.
