    Abstract:
    The effect of a regular haemodialysis session on the plasma concentrations of beta-endorphin, ACTH and cortisol was investigated in 14 patients with end-stage renal disease and 20 healthy controls. Blood for analysis of beta-endorphin, ACTH and cortisol was sampled before and immediately after haemodialysis. In four patients the dialysate was studied for presence of these hormones, but showed no specific activity. The predialysis beta-endorphin, ACTH and cortisol levels did not differ significantly from the control values. The postdialysis levels were significantly higher than the predialysis. Significant linear correlation was found between plasma ACTH and beta-endorphin values in the postdialysis samples. The similarity of plasma beta-endorphin, ACTH and cortisol levels in patients with end-stage renal disease before dialysis and in normal controls indicated integrity of the hypothalamic pituitary-adrenal axis. The significantly increased levels after the dialysis session and the significant correlation between postdialysis plasma beta-endorphin and ACTH suggest that the haemodialysis session was a stressful event.
