The effectiveness of bisphosphonate treatment for post-menopausal osteoporosis depends on patients adhering to the therapeutic regimen. We previously showed that patients prefer a once-monthly regimen and the present follow-up study aimed to analyse patients' motivation for this preference. Women with post-menopausal osteoporosis (n = 2035) completed a(More)
OBJECTIVES To evaluate the function of the hypothalamic-pituitary-adrenal axis and sympathoadrenal system in premenopausal women with rheumatoid arthritis (RA). METHODS Insulin-induced hypoglycaemia (0.1 IU/kg) was produced in 15 glucocorticoid-naive patients with long term RA with low disease activity and in 14 healthy women matched for age and body mass(More)
INTRODUCTION Vitamin K-dependent posttranslational modification of glutamate to gamma-carboxyglutamate is a biochemical feature of the vertebrate blood-clotting cascade. This conversion activates clotting factors and bone proteins, including osteocalcin, a widely accepted marker of osteoblastic activity. Vitamin K antagonists, such as warfarin, inhibit this(More)
OBJECTIVE There is a high prevalence of low bone mineral density (BMD) among patients with inflammatory bowel disease (IBD) although there is a lack of clinical data on the impact of IBD specific medications and recommended vitamin D (VD) and calcium (Ca) supplements on it. DESIGN The cohort consisted of 150 IBD patients. The average change in BMD at the(More)
Articular involvement in acromegaly is one of the most frequent clinical complications and may be present as the earliest symptom in a significant proportion of patients. The involvement of other organs may be of clinical importance and contribute to increased morbidity and mortality of patients suffered from acromegaly. Early diagnosis and proper treatment(More)
OBJECTIVES The aim of our study was to evaluate the relationship between bone mineral density (examined by DXA - dual energy x-ray absorptiometry), vitamin D3 levels and the signs of metabolic syndrome. METHODS We examined 55 subjects (37 women, 18 men, age median 67.8 years) with no history of osteoporosis, suffering from metabolic syndrome (defined as(More)
Inadequate production of cortisol related to inflammation and decrease in adrenal androgen production are hallmarks of hypothalamic-pituitary-adrenal (HPA)-related endocrine findings in rheumatoid arthritis (RA). In particular, lower dehydroepiandrosterone sulfate (DHEAS) levels were consistently found in a subset of premenopausal RA females. Recently,(More)
BACKGROUND Therapeutic adherence determines the efficacy of treatments in the clinical practice. Especially in chronic asymptomatic diseases large differences exist between therapeutic success in clinical studies and clinical practice. The treatment of osteoporosis using bisphosphonates is considerably influenced by the low adherence of patients due to the(More)
Acromegaly is caused by hypersecretion of growth hormone (GH) and consequently of insulin-like growth factor-I (IGF-1) due to pituitary tumor. Other causes, such as increased growth-hormone releasing hormone (GHRH) production, ectopic GHRH production, and ectopic GH secretion, are rare. Growth hormone and IGF-1 play a role in the regulation of bone(More)
Vitamin D deficiency may be one reason for the onset and development of osteoporosis. The aim of the present study was to determine the occurrence rates of hypovitaminosis D in an unselected group of individuals presenting with common medical conditions and hospitalized for long periods. Concentrations of 1,25-(OH)2 D3 were measured in 89 patients (38 males(More)
