Abstract BACKGROUND The effects of vitamin D2 and D3 supplementation on circulating concentrations of 25(OH)D3 require reliable analytical tools for specific determination of 25(OH)D3 and 25(OH)D2. We have developed a highly specific 25-OH Vitamin D3 ELISA with negligible cross-reactivity towards 25(OH)D2. METHODS 25(OH)D3 concentrations were measured in several study participants; 1) 641 healthy men and […]

Abstract AIMS To investigate the influence of food intake on the bioavailability and pharmacodynamic effects of salmon calcitonin (sCT). METHODS A single-blind, randomized, partly placebo-controlled study was conducted in 36 healthy postmenopausal female volunteers aged 62-74 years. The influence of food intake on oral dosing with 0.8 mg of sCT at 22.00 h was evaluated […]

Abstract OBJECTIVE Osteoarthritis (OA) is characterized by increased bone and cartilage metabolism leading to joint damage. The urinary excretion of C-telopeptides of type II collagen (CTX-II) has earlier predicted progression in radiographic OA (ROA)–useful for participant selection in clinical studies of potential disease modifying OA drugs (DMOADs). We investigated the longitudinal interrelationship between CTX-II and […]

Abstract The aim of this study was to assess the bioavailability and pharmacodynamic efficacy of synthetic salmon calcitonin (ssCT) and recombinant salmon calcitonin (rsCT) in healthy postmenopausal women. The study was a single-blind, randomized study. Participants were 36 postmenopausal women 62 to 74 years old, randomly assigned to a comparison of dosing with ssCT (n […]

Abstract BACKGROUND Bone resorption displays marked diurnal variation. Reversible inhibition of bone resorption may result in best possible efficacy when bone resorption peaks. The aim of the study was to assess the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of 0.8 mg of oral salmon calcitonin (sCT) and the effect of timing of drug intake. METHODS […]

Abstract BACKGROUND Osteoarthritis is associated with increased bone resorption and increased cartilage degradation in the subchondral bone and joint. The objective of the present study was to determine whether Tibolone, a synthetic steroid with estrogenic, androgenic, and progestogenic properties, would have similar dual actions on both bone and cartilage turnover, as reported previously with some […]

Abstract BACKGROUND To investigate the influence of water intake and dose timing on the pharmacokinetic and pharmacodynamic parameters of an oral formulation of salmon calcitonin (sCT). METHODS The study was a randomized, partially-blind, placebo-controlled, single dose, exploratory crossover phase I study. 56 healthy postmenopausal women were randomly assigned to receive five treatments. The treatments comprised […]

Abstract UNLABELLED Anti-resorptive strategies may affect bone collagen maturation differently depending on the mode of action. Orally administrated calcitonin resulted in a dose dependent inhibition of bone resorption but did not change bone collagen maturation. This may reflect aspects of bone quality. INTRODUCTION The aim of the present study was to evaluate the effect of […]

Abstract The aim of the present study was to compare a novel marker for high bone turnover with two routine markers for screening in prostate cancer patients. The markers were evaluated in two studies: (a) a cross-sectional study of 170 prostate cancer patients with local disease stratified by +/-lymph node metastases (N 0, N1) compared […]

Abstract UNLABELLED Bone collagen maturation may be important for anti-fracture efficacy as the reduction in risk is only partly explained by a concomitant increase in BMD during anti-resorptive therapy. Different treatments caused diverse profiles in bone collagen degradation products, which may have implications for bone quality. INTRODUCTION The aim of the present study was to […]
