Traditional Chinese Medicine(TCM) Syndrome Classification of Idiopathic Pulmonary Fibrosis(IPF) and Metabolomics

Completed

• Conditions: Idiopathic Pulmonary Fibrosis

• Registration Number: NCT03711435
• Lead Sponsor: Xuzhou Traditional Chinese Medicine Hospital

Brief Summary

The pathogenesis of idiopathic pulmonary interstitial fibrosis is complex, and there is no specific biomarkers, the treatment effect is not such useful. Currently, it is discovered that Chinese medicine treatment may be effective. The investigators select patients with idiopathic pulmonary interstitial fibrosis and healthy controls, use metabolomics to study the biological characteristics of idiopathic pulmonary interstitial fibrosis, screen biomarkers of IPF, and label different TCM syndromes of IPF, explore the biological nature of IPF TCM syndromes, find the biological changes that occur during the development and progression of IPF and explore the metabolite marker clusters of IPF. Furthermore, the results of this study may find its diagnostic significance for IPF and Looking for potential targets for future treatment of IPF.

Primary Outcome Measures

Name	Time	Method
biomarkers detected in metabolites	1 year	Metabolomics of serum based on mass spectrometry.It is non-targeted metabolomics.The study is to find the target metabolite to distinguish IPF.

Secondary Outcome Measures

Name	Time	Method
Pulmonary function Pulmonary function	1 year	Pulmonary function including forced vital capacity(FVC),forced expiratory volume at one second(FEV1),diffusion capacity of lung for carbon monoxide(DLCO)
High-resolution chest CT total score (CT-Tot)	1 year	High-resolution chest CT total score (CT-Tot), which includes the grid shadow and the honeycomb lung. The score range is 0-5, and the larger the score, the more serious the disease.
Six Minute Walk Test(6MWT)	1 year	The six-minute walk test measures the distance an individual is able to walk over a total of six minutes on a hard, flat surface.It is a simple objective indicator for evaluating cardiopulmonary function
St. George's Respiratory Questionnaire	1 year	St. George's Respiratory Questionnaire is measuring impaired health and perceived well-being ('quality of life') in airways disease. the score is 0 to 100，the higher the score is，the worse life quality the patients has.
