GH secretion in normal subjects is periodic, with pulses prevailing during sleep. During the day (basal secretion), GH levels are, in general, undetectable. We studied GH secretion by cluster analysis, collecting samples every 20 min for 24 h in 44 subjects: 11 patients with active acromegaly; 16 "cured" acromegalics, and 17 normal subjects. The purpose of this study was to compare GH secretion between patients with active acromegaly and "cured" patients and between "cured" acromegalic patients and normal controls. The number of pulses detected through the 24-h GH profile was not different between acromegalic patients regardless of disease activity (17.5 +/- 4.4 vs. 15.0 +/- 6.0, respectively), but was different when active acromegalic patients and normal controls were compared (8.1 +/- 1.0; P < 0.05) and when cured acromegalic patients and normal controls were compared (P < 0.05). The GH pulsatile secretion/total GH secretion ratio was higher in normal controls than in acromegalic patients regardless of disease activity. We concluded that 1) the increases in GH pulsatility in active and cured acromegalic patients are similar, but most of the 24-h GH secretion is nonpulsatile; 2) half of the GH secretion in normal subjects occurs during pulses; 3) cured acromegalic patients, even those with normal GH and insulin-like growth factor I levels, do not recover a normal GH secretory pattern.
