[more ▼] Abstract Background: Vitamin D insufficiency has deleterious consequences on health outcomes. In elderly or postmenopausal women, it may exacerbate osteoporosis. Scope: There is currently no clear consensus on definitions of vitamin D insufficiency or minimal targets for vitamin D concentrations and proposed targets vary with the population. In view of the potential confusion for practitioners on when to treat and what to achieve, the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) convened a meeting to provide recommendations for clinical practice, to ensure the optimal management of elderly and postmenopausal women with regard to vitamin D supplementation. Findings: Vitamin D has both skeletal and extra-skeletal benefits. Patients with serum 25-hydroxyvitamin D (25-(OH)D) levels <50 nmol/L have increased bone turnover, bone loss, and possibly mineralization defects compared with patients with levels >50 nmol/L. Similar relationships have been reported for frailty, nonvertebral and hip fracture, and all-cause mortality, with poorer outcomes at <50 nmol/L. Conclusion: The ESCEO recommends that 50 nmol/L (i.e. 20 ng/mL) should be the minimal serum 25-(OH)D concentration at the population level and in patients with osteoporosis to ensure optimal bone health. Below this threshold, supplementation is recommended at 800 to 1000 IU/day. Vitamin D supplementation is safe up to 10,000 IU/day (upper limit of safety) resulting in an upper limit of adequacy of 125 nmol/L 25-(OH)D. Daily consumption of calcium- and vitamin-D-fortified food products (e.g. yoghurt or milk) can help improve vitamin D intake. Above the threshold of 50 nmol/L, there is no clear evidence for additional benefits of supplementation. On the other hand, in fragile elderly subjects who are at elevated risk for falls and fracture, the ESCEO recommends a minimal serum 25-(OH)D level of 75 nmol/L (i.e. 30 ng/mL), for the greatest impact on fracture.

[more ▼] This paper provides recommendations for fair and unbiased relationship between academic scientists and the pharmaceutical industry. INTRODUCTION: Real or perceived problems in the relationship between academics and the industry have been the subject of much recent debate. It has been suggested that academic clinicians should sever all links with the industry-a view that is rarely challenged. METHODS: Academic experts and members of the pharmaceutical industry were invited to an expert consensus meeting to debate this topic. This meeting was organized by the Group for the Respect of Ethics and Excellence in Science. Conflict of interest, competing interest, right and duties of academic scientist, authorship, and staff and student education were discussed. RESULTS: Guidelines for a transparent, ethical, strong, and successful partnership between the academic scientist and the pharmaceutical industry have been provided. CONCLUSIONS: The Group support interactions between the industry and clinicians provided that it is transparent and ethical.

[more ▼] We compared the systemic and clinical effects of ciclesonide (CIC) and fluticasone propionate (FP) administered, in addition to CIC 160 microg x day(-1) and salmeterol 50 microg twice daily, in 32 patients with persistent asthma using a randomised double-blind, placebo-controlled, double-dummy, five-period crossover design. All patients exhibited a provocative concentration leading to a 20% decrease in forced expiratory volume in 1 s (PC(20)) methacholine <8 mg x mL(-1) and a PC(20) adenosine <60 mg x mL(-1). Primary outcome was 24-h serum cortisol suppression after 7 days. Secondary outcomes were changes in PC(20) methacholine and adenosine after 9 days. FP 500 microg x day(-1) and 1,000 microg x day(-1) significantly suppressed cortisol secretion versus placebo by -46.2 (95% confidence interval (CI) -83.8- -8.5) nmol x L(-1) and by -76.1 (95% CI -112.9- -39.3) nmol x L(-1), respectively. Neither dose of CIC (320 nor 640 microg x day(-1)) had a significant suppressive effect (-28.2 (95% CI -65.5-9.2) nmol x L(-1) and -37.3 (95% CI -74.7-0.0) nmol x L(-1), respectively). Differences between FP 1,000 microg x day(-1) and both CIC treatments were statistically significant (CIC 320 microg x day(-1): -48.0 (95% CI -84.8- -11.1) nmol x L(-1); CIC 640 microg x day(-1): -38.8 (95% CI -75.7- -1.9) nmol x L(-1)). Compared with placebo, the increase in PC(20) adenosine after the four treatments was small, but significant. Greater improvements in PC(20) adenosine were seen with FP 500 microg x day(-1) (1.8 (95% CI 1.0-2.6) doubling concentrations) compared with CIC 320 microg x day(-1) (0.9 (95% CI 0.1-1.7) doubling concentrations). No significant difference was seen between CIC 640 microg x day(-1) and FP 1,000 microg x day(-1). For a similar decrease in hyperresponsiveness, cortisol secretion was suppressed significantly with moderate-to-high doses of fluticasone propionate, but not with ciclesonide.

[more ▼] Paget's disease of bone (PDB) is a potentially crippling condition. Pain, fracture, spinal stenosis, nerve entrapment, vascular steal syndrome, secondary osteoarthritis, bone deformity, dental problems, deafness, excessive bleeding during orthopaedic surgery, rare sarcomatous degeneration, and hypercalcaemia constitute complications that may impair the quality of life. The therapeutic approach varies from symptomatic (analgesics, anti-inflammatory drugs) to more specific drugs such as increasingly potent bisphosphonates. Studies such as the PRISM study should in the future help to determine the superiority or not of aggressive treatment over symptomatic treatment in the prevention of complications. Various oral and/or intravenous (i.v.) bisphosphonates have been tested and are currently on the market. The most recently available nitrogen-containing bisphosphonate, i.v. zoledronic acid, is the most potent therapy available for the treatment of PDB. Its therapeutic efficacy, its long-term effect on biologic activity and its good tolerance currently supports its use as a first-line therapeutic option in patients suffering from PDB.
