[The problem of osteopenia in a iodine-deficit area].
The aim of the study was to evaluate the condition of bone system in 335 subjects with thyroid gland dysfunction (TGD), residing in iodine deficit areas. Among the subjects there were 116 individuals with thyrotoxicosis (TT), and 219--with hypothyroidism (HT). The control group included 200 practically healthy people of comparable age and sex. The examination included: evaluation of pain syndrome intensity using a 4-point scale; revealing of atraumatic fracture background; measurement of serum levels of thyroid stimulating hormone (TSH) andfree thyroxin by immune-enzyme assay; measurement of bone mineral density (BMD) by dual-energy x-ray absorptiometry using a Dexa-Scan DX-10 device (Direx, Israel) with evaluation of the results according to 1994 WHO recommendations. 79.3% of TT patients and 68% of HT patients suffered from pain syndrome. The difference in atraumatic fracture rate between the groups was insignificant. The mean BMD values in subjects with TGD dysfunction corresponded to osteopenia, while in the control group they were within normal limits. The difference in osteopenic syndrome rate between TT and HTpatients was insignificant, although osteopenia was revealed in 25% of TT patients. The frequency of BMD decrease grew with age; however, this parameter was higher in all groups of patients with TGD vs. control. The most prone to osteopenia are postmenopausal women regardless of thyroid dysfunction character; difference in BMD decrease frequency between men and women with preserved menstrual function, was insignificant. Osteopenic syndrome was more frequent in men with TGD then in healthy men. Thus, in residents of iodine deficit areas TGD is a factor of BTMD decrease.
