Vitamin D levels and associated factors: a population-based study in Switzerland.

QUESTIONS UNDER STUDY: To update the prevalence of vitamin D insufficiency and to identify factors associated with vitamin D status in the Swiss adult population. METHODS: Data from the 2010-2011 Swiss Study on Salt intake, a population-based study in the Swiss population, was used. Vitamin D concentration in serum was measured by liquid chromatography- tandem mass spectrometry. Major factors that influence vitamin D levels were taken into account. Survey statistical procedures were used to estimate means and prevalences of vitamin D levels and status. Monthly-specific tertiles of vitamin D and ordinal logistic regression were used to determine the associations of covariates of interest with vitamin D status. RESULTS: The prevalences of vitamin D insufficiency (serum 25-hydroxyvitamin D: 20-29.9 ng/ml) and deficiency (<20 ng/ml) were the highest in the January-March period; 26.4% (95%CI: 21.6-31.7) and 61.6% (95%CI: 56.0-67.0), respectively. In the same period, more than 9 of ten men were vitamin D insufficient or deficient. Each unit increase of Body Mass Index was associated with an 8% decreased likelihood of being in a higher vitamin D tertiles. Oral contraceptive, altitude, urinary excretion of calcium, use of vitamin D supplement or treatment, high wine consumption, physical activity were associated with vitamin D tertiles. Compared to the French-speaking region, the Italian-speaking region was independently associated with a higher likelihood of being in higher vitamin D tertiles (OR: 1.66, 95%CI: 1.14-2.43). CONCLUSIONS: Low levels of vitamin D are common among Swiss adults, in particular during winter months and outside the Italian-speaking region.

Acute life-threatening presentation of vitamin d deficiency rickets.

Context: Clinical manifestations of vitamin D deficiency rickets are widely described; however cardiorespiratory arrest is an extremely rare presentation. Objective: The aim of this paper is to present the symptoms of severe vitamin D deficiency rickets and to highlight the importance of vitamin D prophylaxis in infants. Results: We report a case of a 16-month-old infant who presented to emergency room with a stridor that evolved into a full cardiorespiratory arrest secondary to hypocalcemia. Medical history revealed that the infant was exclusively breastfed without vitamin D supplementation until the age of 10 months. Due to cultural habits, his diet was also grossly deficient in dairy products. Physical exam revealed clinical signs of rickets. Laboratory test showed severe hypocalcemia, elevated alkaline phosphatase, normal serum phosphorous, decreased 25(OH) cholecalciferol, increased intact parathyroid hormone level, and normal urine calcium excretion. The radiography of the wrist showed evidence of cupping, fraying, metaphyseal widening, and demineralization of the distal radial and ulnar metaphyses. The bone mineral density of the lumbar spine measured by dual x-ray absorptiometry showed a Z-score below -2 SD. His cardiorespiratory arrest secondary to hypocalcemia was therefore attributed to severe nutritional rickets. Conclusion: Vitamin D deficiency rickets can be life threatening. Vitamin D supplementation is therefore crucial, especially in breastfed infants and some ethnic minorities (dark-skinned people, poor sun exposure), more at risk for developing severe rickets if not supplemented.

Quantitative distribution of parvalbumin, calretinin, and calbindin D-28k immunoreactive neurons in the visual cortex of normal and Alzheimer cases.

The distribution of parvalbumin (PV), calretinin (CR), and calbindin (CB) immunoreactive neurons was studied with the help of an image analysis system (Vidas/Zeiss) in the primary visual area 17 and associative area 18 (Brodmann) of Alzheimer and control brains. In neither of these areas was there a significant difference between Alzheimer and control groups in the mean number of PV, CR, or CB immunoreactive neuronal profiles, counted in a cortical column going from pia to white matter. Significant differences in the mean densities (numbers per square millimeter of cortex) of PV, CR, and CB immunoreactive neuronal profiles were not observed either between groups or areas, but only between superficial, middle, and deep layers within areas 17 and 18. The optical density of the immunoreactive neuropil was also similar in Alzheimer and controls, correlating with the numerical density of immunoreactive profiles in superficial, middle, and deep layers. The frequency distribution of neuronal areas indicated significant differences between PV, CR, and CB immunoreactive neuronal profiles in both areas 17 and 18, with more large PV than CR and CB positive profiles. There were also significantly more small and less large PV and CR immunoreactive neuronal profiles in Alzheimer than in controls. Our data show that, although the brain pathology is moderate to severe, there is no prominent decrease of PV, CR and CB positive neurons in the visual cortex of Alzheimer brains, but only selective changes in neuronal perikarya.
