Abstract. To examine the response of growth hormone (GH) to growth hormone releasing factor (GHRF) in patients on haemodialysis, we performed the acute G H R F test (50 \x% administered intravenously as a bolus) in 10 uraemic male patients on haemodialysis and eight normal controls. Each patient was tested before and after a haemodialysis session (at 08.30 and 12.30). Controls were tested on the same time schedule. At 08.30, patients had significantly greater basal and peak GH values (2.5 ±0.6 and 27.8 ± 5.5 ug/1) than controls (0.68 ±0.1 and 11.5 ± 4 ug/1). After the haemodialysis session, basal and peak values declined significantly (/ ) the urea kinetic model, showed a mean Kt V value of 1.12 ±0.1 (range 0.9-1.4). There were no undernourished patients and all had protein catabolic rates < 0.9 g kg day. All patients received aluminium hjdroxide, calcium supplementation and multivitamins (complex B plus C); none was treated with beta-blocking or other antihypertensive drugs. The control group consisted of eight healthy males (mean age 39.1 ±2.7 years, range 28-55 years). All subjects were informed of the nature of the study and consent was obtained. The study conformed to accepted ethical standards and legal regulation.

Patients showed significantly greater pre-haemodialysis growth hormone values (2.82*0.6 £g 1) than did healthy controls at 08.30 (0.67±0.1 ug 1) (P
