Vitamin D Deficiency and Effect of Its Supplementation on Interstitial Lung Diseases(ILD).

2019-09-27 06:30:45 | BioPortfolio


This study evaluates serum level of Vitamin D in Interstitial Lung Diseases in patients with Interstitial Lung Diseases other than connective tissue diseases associated-Interstitial Lung Diseases and effects of its supplementation.

All patients will receive the standard regimen of treatment (corticosteroids and immunosuppressive drugs)and will be randomly assigned to either Group 1:who will receive Vitamin D supplementation (Interventional group)or Group 2:who will not receive Vitamin D supplementation(Control group).


Pulmonary fibrosis was due to chronic inflammation and disordered wound healing in response to damage induced by a variety of agents such as viral infection and radiotherapy or environmental is characterized by accumulation of myofibroblasts and excessive deposition of the extracellular matrix.Epithelial cells undergoes epithelial mesenchymal transition (EMT).

Supplementation with vitamin D or its analogs suppresses lung fibrosis via triggering anti-fibrotic effect through attenuation of transforming growth factor beta (TGF-B).vitamin D can reduce TGF-B expression and attenuate TGF-B induced epithelial mesenchymal transition in lung fibroblast and epithelial cells.

The interstitial lung disease-gender-age-physiology (ILD-GAP) index and staging system have been reported as a clinical prognostic factor for ILD, including all ILD subtypes.

High Diagnostic Accuracy of Transbronchial Cryobiopsy in Fibrotic Interstitial Lung Diseases Compared to Final Explant Diagnosis.

A diagnostic lung biopsy may be required in some cases of fibrotic interstitial lung diseases (ILD). Transbronchial cryobiopsy has been suggested as a possible alternative to surgical lung biopsy. How...

Medical and Biotech [MESH] Definitions

A diverse group of lung diseases that affect the lung parenchyma. They are characterized by an initial inflammation of PULMONARY ALVEOLI that extends to the interstitium and beyond leading to diffuse PULMONARY FIBROSIS. Interstitial lung diseases are classified by their etiology (known or unknown causes), and radiological-pathological features.

A cytochrome P-450 enzyme that has specificity for CHOLECALCIFEROL (Vitamin D3). It hydroxylates the molecule at carbon position 24.

A group of interstitial lung diseases with no known etiology. There are several entities with varying patterns of inflammation and fibrosis. They are classified by their distinct clinical-radiological-pathological features and prognosis. They include IDIOPATHIC PULMONARY FIBROSIS; CRYPTOGENIC ORGANIZING PNEUMONIA; and others.

Hydroxy analogs of vitamin D 3; (CHOLECALCIFEROL); including CALCIFEDIOL; CALCITRIOL; and 24,25-DIHYDROXYVITAMIN D 3.

A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
