We wanted to test the hypotheses that blood pressure level was lower, that the variability of blood pressure and blood glucose was reduced, and that quality of life was improved when glucose was added to the dialysis fluid.

The purpose of the study was to determine the effect of glucose added to the dialysis fluid on 1.blood pressure and variation in blood pressure, 2.blood glucose and variation in blood glucose, and 3.quality of life in patients treated with chronic maintenance hemodialysis in a randomized, placebo-controlled, unblinded cross-over study.

Inclusion Criteria:

• age more than 18 years, both men and women, and hemodialysis treatment for more than three months

Exclusion Criteria:

• treatment with hemodiafiltration, change to another dialysis modality, renal transplantation, alcohol abuse defined as more than 21 drinks a week for men and more than 14 drinks a week for women, and unwillingness to participate.
