Background/Aims: Acromegaly is frequently accompanied with impaired glucose tolerance (IGT) and diabetes mellitus ( DM). It remains unclear which factors determine the abnormal glucose tolerance status in acromegaly. In addition, diverse actions of GH and IGF-I in regulating glucose metabolism in acromegaly have not yet been well elucidated. The aim of this study was to investigate the factors associated with abnormal glucose tolerance in acromegaly. Subjects and Study Design: We conducted a retrospective cross-sectional study that included 48 patients with active acromegaly. The subjects were divided into two groups by the results of 75 g OGTT: normal glucose tolerance (NGT) group (n = 19) and IGT+ DM group (n = 29). Results: Systolic blood pressure (SBP) was significantly higher in the IGT+ DM than in the NGT group. Homeostasis model assessment of beta-cell function (HOMA-beta) was significantly decreased in the IGT+ DM group compared with the NGT group. Although serum GH or IGF-I levels were not different between the two groups, the IGF-I/GH ratio in the IGT+ DM group was significantly lower than that in the NGT group. Conclusions: We have shown that a low serum IGF-I/GH ratio was associated with abnormal glucose tolerance in acromegaly. We propose that the IGF-I/GH ratio is a useful marker to understand the metabolic status in acromegaly. Copyright (c) 2008 S. Karger AG, Basel.
