Administration of a corticosteroid with minor osteopenic effects is considered an effective prevention of glucocorticoid osteoporosis. Deflazacort, an oxazolinic derivative of prednisolone, is reported to be less harmful to cancellous bone mass than other equally effective corticosteroids. However, comparative long-term studies, particularly on trabecular(More)
A number of studies have shown that an excess of glucocorticoids induces osteoporosis, but the mechanism(s) and the time course of the reduction of bone mass remain uncertain. In order to clarify this issue we carried out a longitudinal clinical and histomorphometric study of patients requiring long-term glucocorticoid treatment. In 23 patients (9 men, 10(More)
Transforming growth factor beta1 (TGF-beta1) is abundant in bone and is an important regulator of the osteoclastic-osteoblastic interaction (coupling). The sequence variation, 713-8delC in the TGF-beta1 gene has previously been found to be associated with very low bone mass in osteoporotic women and with increased bone turnover in both osteoporotic and(More)
The synthesis of the active form of vitamin D, 1,25-dihydroxyvitamin D (1,25-(OH)2D), is thought to be relatively insensitive to the serum concentration of its precursor, 25-hydroxyvitamin D (25-OH-D). We compared the effect of oral administration of 25-OH-D3 (50 micrograms per day for one month) on serum concentrations of calcium, phosphate, parathyroid(More)
The effect of a single intravenous (i.v.) infusion of 5 mg alendronate was studied in ten patients with Paget's disease, six patients with primary hyperparathyroidism and ten osteopenic postmenopausal women. Urinary hydroxyproline excretion significantly decreased within few days in all patients (from 113 +/- 67.9 to 58 +/- 35 mmol/mol Cr in Paget's(More)
The delayed cutaneous hypersensitivity to seven ubiquitous antigens (Multitest CMI, Istitute Mĕrieux) was evaluated in normal healthy volunteers before and at the time of intramuscular administration of 50 (12 subjects) or 50 + 50 (nine subjects) units of salmon calcitonin or 2 ml of saline (eight subjects). The delayed cutaneous hypersensitivity, in terms(More)
Hypertension and coronary artery disease are intimately connected. The migration of circulating monocytes into the subendothelial occurs through the expression of some adhesion molecules on endothelial cells. The nuclear factor (NF)-kappaB, a redox-sensitive element, plays a key role in adhesion molecule gene induction. In this study we have compared the(More)
Deflazacort (DF) has been claimed to be provided with a reduced distribution into the central nervous system, therefore it is conceivable that this glucocorticoid holds a lower inhibitory effect on GH secretion. To test this hypothesis we studied the GH response to insulin tolerance test (ITT) in two matched groups of patients given equivalent doses of DF(More)
BACKGROUND Implantable cardioverter defibrillators (ICDs) are increasingly employed in patients affected by congestive heart failure (CHF) and sleep disordered breathing (SDB) is frequent in this population. HYPOTHESIS To investigate SDB prevalence and influence on appropriate ICD discharges in CHF patients. METHODS A total of 22 consecutive ICD(More)
