    Abstract:
    In a double-blind, placebo-controlled trial of recombinant human growth hormone (rhGH) comprising 20 chronic enfeebled haemodialysed patients, the clinical benefit of daily growth hormone treatment for six months was evaluated. Nine patients (five male, four female) were treated with rhGH 4 i.u./m2/day and eleven with placebo (seven male, four female). Their mean age was 46.5 years (range 18-68). No difference in mean age was found between the groups. A significant increase in insulin-like growth factor I (IGF-I) was observed in the rhGH-treated group (200 to 527ng/ml, p = 0.01), while a decrease was noticed in the placebo group (285 to 219ng/ml, p = 0.02). S-GH did not change significantly in either group, and there were no differences between the two groups in terms of weight, haemoglobin, s-albumin, -urea or -creatinine, which all remained unchanged during the trial. Patients' lean body mass, as measured by DXA-scanning, increased significantly in the rhGH-treated group (43.4 to 46.7kg, p = 0.004), while no change was observed in the placebo group (44.9 to 45.2kg, p = 0.76). The changes in lean body mass between the two groups were significant, p = 0.001. Left ventricular muscle mass increased significantly (227 to 286g, p = 0.03) in the rhGH-treated group, but not in the placebo group (292 to 253g, p = 0.3). The changes in left ventricular muscle mass between the two groups were significant (p = 0.02). The maximal working capacity decreased slightly and insignificantly in both groups, when measured by bicycle ergometry. Isometric muscle contraction force and endurance did not change significantly in either group. Patients' opinion about the influence of the treatment on their general well-being and working capacity, evaluated blindly on a subjective scale, improved significantly in the rhGH-treated group (9.7 to 12.6, p = 0.02), while no change was experienced in the placebo group (9.9 to 10.7, p = 0.2). No difference was however demonstrable between the two groups (p = 0.4). Thus we conclude that adult patients in long-term haemodialysis treated with rhGH experienced an increase in their lean body mass and left ventricular muscle mass. This increase in muscle mass did not, however, improve muscle contraction force or endurance when measured objectively. The rhGH-treated patients nevertheless had a subjective feeling of a slight improvement in their general wellbeing.
