OBJECTIVE: We evaluated metabolic and cardiac parameter changes with GH-therapy. DESIGN: Sixteen adults with childhood-onset hypopituitarism receiving pituitary hormone replacement, except GH-replacement, were assessed at baseline and after 6 and 12 months of GH-replacement. Sixteen healthy adults matched for sex, age, weight, height, body mass index, and body surface area served as the control group to compare cardiac function in both groups. RESULTS: All patients had GH-deficiency. After 12 months, serum insulin-like growth factor-1 levels normalized. Basal glucose or insulin levels had no alterations. The low/high density lipoprotein-cholesterol ratio decreased (3.18+/-1.32 x 2.17+/-0.8, p<0.001). Percent lean body mass increased (69.9+/-5.5 x 78.4+/-8.1%), and percent fat body mass decreased (30.1+/-5.5 x 21.6+/-8.1%) (both, p<0.001). Before treatment, patients had decreased left ventricular (LV) echocardiographic morphologic indexes, which were corrected (initial versus 12 months): interventricular septal thickness (0.68+/-0.06 x 0.78+/-0.06 cm), LV posterior wall thickness (0.69+/-0.07 x 0.78+/-0.05 cm), and LV mass index (58.9+/-11.0 x 71.1+/-9.4 g/m(2)) (all, p<0.001). Exercise capacity improved, as assessed by oxygen consumption (7.84+/-1.44 x 9.67+/-1.74 METS, p<0.001). CONCLUSIONS: GH-replacement seems to reduce cardiovascular risks in adults with childhood-onset GH-deficiency.
