TCM Cohort for Elderly COPD

A Prospective Traditional Chinese Medicine Cohort Study of Chronic Obstructive Pulmonary Disease in the Elderly

This study evaluates the real-world clinical efficacy of traditional Chinese medicine (TCM) in elderly Chronic obstructive pulmonary disease (COPD) patients and explores syndrome characteristics and their associations with biomarkers.

Studieoversikt

Detaljert beskrivelse

This prospective cohort study, with TCM as the exposure, will enroll 2,386 elderly COPD patients for a 1-year follow-up. The primary evaluation uses the annual acute exacerbation rate as the outcome to evaluate the clinical efficacy of TCM. In addition, the study will investigate the characteristics of TCM syndromes.

Based on the cohort, we will collect peripheral blood, exhaled breath condensate, sputum, and tongue coating samples from 200 elderly COPD patients with four typical TCM syndromes, 200 non-elderly COPD patients with corresponding syndromes, and 50 healthy volunteers. Multi-omics approaches will be used to identify TCM syndrome-related biomarkers.

Designdetaljer

Kohorter og intervensjoner

Gruppe / Kohort
Intervensjon / Behandling
Traditional Chinese Medicine cohort
Regulated use of Chinese medicine treatment protocols is included as an exposure factor.
According to the standardised use of TCM protocols, the group is divided into an exposed group (TCM cohort) and an unexposed group (non-TCM cohort).
Non-Traditional Chinese Medicine cohort
Other elderly COPD patients who do not meet the inclusion criteria for traditional Chinese medicine cohort, are classified into the non-traditional Chinese medicine cohort.
Alle intervensjonstiltak som ikke oppfyller kriteriene for TCM-eksponering, blir sett på som ikke-TCM-eksponering.

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Annual acute exacerbation rate
Tidsramme: Up to week 52.
The annual acute exacerbation rate will be calculated in each group at the end of the trial.
Up to week 52.

Sekundære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Forced Vital Capacity (FVC)
Tidsramme: Evaluate the FVC at weeks 26 and 52.
FVC will be applied to assess pulmonary function.
Evaluate the FVC at weeks 26 and 52.
Forced Expiratory Volume in One Second (FEV1)
Tidsramme: Evaluate the FEV1 at weeks 26 and 52.
FEV1 will be applied to assess pulmonary function.
Evaluate the FEV1 at weeks 26 and 52.
FEV1/FVC Ratio
Tidsramme: Evaluate the FEV1/FVC Ratio at weeks 26 and 52.
FEV1/FVC Ratio will be applied to assess pulmonary function.
Evaluate the FEV1/FVC Ratio at weeks 26 and 52.
6-Minute Walk Distance (6MWD)
Tidsramme: Evaluate the 6MWD at weeks 26 and 52.
The 6MWD will be applied to evaluate the exercise capacity. The higher values indicate the better exercise capacity.
Evaluate the 6MWD at weeks 26 and 52.
COPD Assessment Test (CAT) Score
Tidsramme: Evaluate the CAT Score at weeks 13, 26, 39 and 52.
The CAT score is a questionnaire used to evaluate the impact of COPD on patients' health status, which includes eight items: cough, phlegm, chest tightness, breathlessness, activity limitation, confidence in leaving home, sleep, and energy. The total CAT score ranges from 0 to 40, with higher scores indicating a greater disease burden and poorer health status.
Evaluate the CAT Score at weeks 13, 26, 39 and 52.
Modified Medical Research Council (mMRC) Dyspnea Scale
Tidsramme: Evaluate the mMRC at weeks 13, 26, 39 and 52.
The mMRC is a scale used to evaluate the severity of dyspnea in patients, which consists of a single item with five grades ranging from 0 to 4. Higher grades indicate more severe dyspnea and greater limitations in daily activities.
Evaluate the mMRC at weeks 13, 26, 39 and 52.
St. George's respiratory questionnaire (SGRQ) total scores
Tidsramme: Evaluate the SGRQ Score at weeks 13, 26, 39 and 52.
The SGRQ is a scale used to evaluate the quality of life of patients, which includes three dimensions: symptoms, mobility, and the impact of disease on daily life, with a total of 50 items. The total score range of SGRQ is usually between 0 and 100, with higher scores leading to poorer quality of life.
Evaluate the SGRQ Score at weeks 13, 26, 39 and 52.
