Abstract
- Objective: So far, high prevalence of metabolic symptoms accompanying diffuse idiopathic skeletal hyperostosis (DISH) appears not definitely elucidated because of their possible origin from other disorders such as diabetes and/or body mass differences. From such reasons this study was aimed to compare non-diabetic DISH patients to a group of age and BMI matched controls in order to distinguish the influence of DISH proper on metabolic parameters free of additional metabolic effects caused by diabetes and/or body weight differences.<br />Methods: Both groups of patients were subjected to oral glucose tolerance test (OGTT) and fasting serum levels of glucose, insulin, C-peptide, growth hormone, insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGF-BP3) were assayed. Fasting serum total cholesterol, HDL cholesterol, triglycerides, non-esterified fatty acids (NEFA) and uric acid were determined as well. The indices of insulin sensitivity and insulin secretion were calculated.<br />Results: With the exception of decreased NEFA serum level and decreased insulinogenic index and insulin/C-peptide ratio in DISH patients any other significant differences in serum parameters and indices of insulin sensitivity were not found.<br />Conclusions: The data obtained suggest impaired beta-cell pancreatic stimulation and increased insulin hepatic extraction in DISH. It is assumed that the above mentioned conditions, if persisting for a long time, might lead to decreased ability of insulin to maintain normal serum glucose level and consequently to insulin resistance which is highly prevalent in symptomatic DISH patients.
