Vitamin D serum level and chronic obstructive lung disease
متن کاملVitamin D and lung disease.
The classic role of vitamin D in the regulation of calcium and phosphate metabolism, and its effects on bone health, are well established. More recently a critical role in immunity and respiratory health has been proposed. This arises from evidence for the capacity to generate the active metabolite, 1α,25-dihydroxyvitamin D3 (1,25(OH)D3), locally in many tissues beyond the kidney; expression of...
متن کاملVitamin D and lung function.
Afzal et al recently reported that low plasma 25-hydroxyvitamin D is associated with a decline in lung function and chronic obstructive pulmonary disease (COPD). While this finding persisted after adjustment for possible confounding variables, and concurs with the findings of others, we believe it might still be spurious. First, we suggest the association between plasma vitamin D and lung funct...
متن کاملAvailability of Vitamin D UV and a “Vitamin D index” for public UV exposure advice
Vitamin D production in the skin by UV exposure is the most promising means of alleviating the worldwide burden of vitamin D deficiency. However, we demonstrate that Vitamin D production cannot be quantified by the current UV Index, which is based on the erythemal action spectrum. Large disagreement was observed when comparing (by computer simulation) the daily levels of erythemal UV and UV wei...
متن کاملLung clearance index in adults with non-cystic fibrosis bronchiectasis
BACKGROUND Lung clearance index (LCI) is a measure of abnormal ventilation distribution derived from the multiple breath inert gas washout (MBW) technique. We aimed to determine the clinical utility of LCI in non-CF bronchiectasis, and to assess two novel MBW parameters that distinguish between increases in LCI due to specific ventilation inequality (LCIvent) and increased respiratory dead spac...
