Vitamin D deficiency causes pulmonary disease

New research shows that vitamin D deficiency is widespread among patients with interstitial lung disease, most prevalent in patients with connective tissue diseases.

Researchers at the Medical colleges of the University of Cincinnati analyzed vitamin D levels in 67 patients with interstitial lung disease and diseases of connective tissue from51 patients with other forms of connective tissue disease. The results showed that the frequency of complete lack of vitamin D were 38% and its failure in 59%.

Those patients with interstitial lung disease and connective tissue diseases are a farbetter chance of vitamin D deficiency (52 percent v. 20 percent) and its failure (79percent v. 31 percent) compared to other forms of interstitial lung disease. In patientswith interstitial lung disease and connective tissue diseases, reduced levels of vitamin Dis strongly associated with reduced lung function. The researchers conclude that vitaminD plays a role in the pathogenesis of interstitial lung disease.
