Objectives: Validation of the Architect 25-OH vitamin D assay. Design and methods: Determination of repeatability, reproducibility, accuracy profile and 25(OH)-vitamin D2 recovery on native samples. Comparison with DiaSorin Liaison and RIA. Results and conclusion: Coefficients of variation: b6% (13.6 ng/mL) and 2.2% (78.1 ng/mL). Functional sensitivity: 5 ng/mL. Accuracy profile shows that the method is validated between 13.6 and 78.1 ng/mL. Recovery of 25(OH)D2: 75,8%( 95% CI: 61.9–89.7%). Good correlation with DiaSorin RIA and Liaison b50 ng/mL; above this threshold a systematic positive bias was observed. [less ▲]

A poor vitamin D status, i.e. low serum levels of 25-hydroxyvitamin D (25[OH]D), is common in the general population. This finding is of concern not only because of the classic vitamin D effects on musculoskeletal outcomes, but also because expression of the vitamin D receptor (VDR) and vitamin D metabolizing enzymes in the heart and blood vessels suggests a role of vitamin D in the cardiovascular system. VDR-knockout mice suffer from cardiovascular disease (CVD) and various experimental studies suggest cardiovascular-protection by vitamin D, including anti-atherosclerotic, anti-inflammatory and direct cardio-protective actions, beneficial effects on classic cardiovascular risk factors as well as suppression of parathyroid hormone (PTH) levels. In epidemiological studies, low levels of 25(OH)D are associated with increased risk of CVD and mortality. Data from randomized controlled trials (RCTs) are sparse and have partially, but not consistently, shown some beneficial effects of vitamin D supplementation on cardiovascular risk factors (e.g. arterial hypertension). We have insufficient data on vitamin D effects on cardiovascular events, but meta-analyses of RCTs indicate that vitamin D may modestly reduce all-cause mortality. Despite accumulating data suggesting that a sufficient vitamin D status may protect against CVD, we still must wait for results of large-scale RCTs before raising general recommendations for vitamin D in the prevention and treatment of CVD. In current clinical practice the overall risks and costs of vitamin D supplementation should be weighed against the potential adverse consequences of untreated vitamin D deficiency [less ▲]

We report the case of a patient with severe muscular and articular tenderness that caused almost complete immobility. This subject had severe hypophosphatemia due to hyperphosphaturia. Fibroblast growth factor 23 (FGF-23) was abnormally high and the diagnostic of tumor-induced osteomalacia was made. Despite multiple tests, the tumor was not localized. In this report, we discuss different possible investigations to localize the tumor. Lastly, we review the potential therapy available when tumor is not found and can thus not be excised. [less ▲]
