NCT04042519

Brief Summary

Targeted metabolomics research was conducted on patients with chronic obstructive pulmonary disease (COPD). The correlation analyst between inflammation-related metabolites and lung function was analyzed by explored the metabolic pathways of inflammation-related omega-6 and omega-3 and combining them with lung function.

Outcome Measures

Primary Outcomes (5)

  • Forced expiratory volume in 1 second (FEV1)

    The FEV1 percentage of predicted value is an important indicator in the diagnosis and treatment of COPD, and plays an important role in the severity rating. * level (mild) : FEV1 / FVC \< 70%, FEV1% pred \> 80%. Ⅱ level (moderate) : FEV1 / FVC \< 70%, 50% ≦ FEV1% pred\< 80%. Ⅲ level (severe) : FEV1 / FVC \< 70%, 30% ≦ FEV1% pred \< 50%. IV level (very severe) : FEV1/FVC\<70%, FEV1% pred \< 30%, or FEV1% pred \<50% with chronic respiratory failure.

    October 1, 2016 to October 1, 2018

  • Forced vital capacity (FVC)

    FVC is an important index to determine the resistance of respiratory tract. FEV1 and FEV1/FVC% in patients with obstructive airway obstruction, such as patients with chronic obstructive pulmonary disease, were reduced due to airway obstruction and prolonged expiratory.

    October 1, 2016 to October 1, 2018

  • FEV1/FVC ratio

    This index is an important basis for the diagnosis of COPD and is crucial in the early stage of the disease to the later stage of the evaluation.

    October 1, 2016 to October 1, 2018

  • The metabolites of Omega-6 inflammatory indicator

    Agilent 1290 Infinity LC system (UHPLC, Santa Clara CA) was used for the targeted determination of metabolites in the serum of subjects. Omega6 metabolites are closely related to inflammation and have been shown to be involved in a variety of diseases such as COPD, rheumatism, cardiovascular disease, et al.

    October 1, 2016 to October 1, 2018

  • The metabolites of Omega-3 inflammatory indicator

    As an important anti-inflammatory factor, omega-3 is widely used in chronic inflammatory diseases, which can fight against the pro-inflammatory metabolites of omega-6.

    October 1, 2016 to October 1, 2018

Secondary Outcomes (2)

  • C-reaction protein

    October 1, 2016 to October 1, 2018

  • Leukocyte Count

Interventions

This Jaeger lung function instrument of Germany is used to test the pulmonary ventilation function of COPD patients. Since the condition requires drug control and treatment, the drug cannot be stopped.

Sampling MethodProbability Sample
Study Population

Based on the global initiative for chronic obstructive pulmonary disease, the 80 confirmed stable COPD patients with mild-to-moderate were involved, 80 COPD patients with severe and very severe, and age, sex, all matching 40 cases without lung disease. The participants information was collected. Whole blood and pulmonary function were examined at three time points: admission, six months and one year, at the same time, targeted metabolomic analysis method are applied to detect serum metabolites, According to the access to assess the different severity of COPD in the stable period and the level of metabolites in different admission periods.
