0001). Fasting lipids
did not change in either treatment group from baseline to week 40, and did not differ between groups. Fasting plasma glucose increased to a significantly greater extent in the GH group (0.4 mM; IQR 0.1, 0.8 mM) than in the placebo group (0.0 mM; IQR −0.2, 0.2 mM) (P=0.008). Homeostasis model assessment insulin resistance (HOMA-IR) did not change in the GH or placebo group, and did not differ significantly between groups. The 2-h plasma glucose level during an oral glucose tolerance test did not change in either treatment group. The number of patients displaying impaired glucose tolerance (IGT) (defined as 2-h plasma glucose in oral glucose tolerance test ≥7.8 but <11.1 mM) was eight patients (29%) in the GH group vs. five patients (28%) in the PFT�� placebo group at baseline, and seven patients (29%) in the GH group vs. six patients (33%) in the placebo group at 40 weeks, with no significant difference between groups. The physical ACP-196 chemical structure health score and mental health score at baseline were high in both study groups, at 58 (52, 60) and 55 (53, 59) in the placebo group
and 57 (53, 60) and 56 (47, 62) in the GH group, respectively, and remained unchanged during the study period. At baseline, VO2max was 2712 mL O2/min (2569, 2992 mL O2/min) in the placebo group and 2277 mL O2/min (1902, 2661 mL O2/min) in the GH group. VO2max increased significantly in the GH group (by a median of 85 mL O2/min; IQR −17, 307 mL O2/min; P=0.04) while it remained unchanged in the placebo group, the difference between study groups being significant (P=0.033). A significant reduction in abdominal visceral fat in HIV-infected patients receiving a fixed dose of 0.7 mg/day of rhGH for 40 weeks, administered during the afternoon, was demonstrated in this double-blind placebo-controlled study. The net treatment effect of rhGH administration on VAT area
was a reduction of 17% and trunk fat mass decreased by 15%, while no concomitant changes in measures of peripheral Gefitinib price fat were observed in the GH group compared with the placebo group. Glucose tolerance was preserved during treatment. The data presented show that the lipolytic effects of rhGH observed previously at pharmacological doses [5,6,10] also operate at the much lower high physiological dose of rhGH used in the current study. However, in contrast to the previously reported deterioration in glycaemic measures associated with a supra-physiological dosage of rhGH, a high physiological dose of rhGH was accompanied by no clinically relevant deterioration in glucose metabolism. In a previous pilot study of 1 mg rhGH/day in five patients for 6 months, a 2-kg mean reduction in trunk fat mass was observed, and in another pilot study of 0.7 mg rhGH/day in six patients for 16 weeks, a nonsignificant reduction in mean trunk fat mass of 400 g was found [16,17]. A crossover study with a mean dose of 0.
