Brief Summary

The objectives of this study are to evaluate Efficacy and safety of beta-glucan supplement in chronic obstructive pulmonary disease patients.

Detailed Description

There are 72 patients in this study. They are randomly divided into 2 groups which are beta-glucan supplement group and placebo group. The supplement will be taken 1 capsule/day for 12 weeks. Forced expiratory volume in 1 second/Forced vital capacity, Modified Medical Research Council Dyspnea Score, Breathlessness, Cough, and Sputum Scale, 6 Minute Walk Test, Diffusing capacity for carbon monoxide, Tumor necrosis factor alpha, Interleukin-6, C-reactive protein, glutathione, aspartate transaminase, alanine transaminase, alkaline phosphatase, creatinine, and blood urea nitrogen are assessed before and after taking supplement 6 and 12 weeks.

Primary Outcome Measures
NameTimeMethod
Forced expiratory volume in 1 second/Forced vital capacity12 weeks

Forced expiratory volume in 1 second/Forced vital capacity in % (high value means better pulmonary function)

Secondary Outcome Measures
NameTimeMethod
Aspartate transaminase12 weeks

Aspartate transaminase refers to liver function (U/L)

6-minute walk test12 weeks

6-minute walk test in walking distance in 6 minutes (meters) (high value means better performance)

Interleukin-612 weeks

Interleukin-6 is a biomarker of inflammation (picogram/ml) (high value means high risk of inflammation)

Creatinine12 weeks

Creatinine refers to renal function (mg/dl)

Breathlessness, Cough, and Sputum Scale12 weeks

Breathlessness, Cough, and Sputum Scale shows in severity scale (scale 0 to 4 means no symptom to high severity)

Chronic obstructive pulmonary disease assessment test12 weeks

Chronic obstructive pulmonary disease assessment test in scale 0 to 5 (high value means better quality of life)

C-reactive protein12 weeks

C-reactive protein refers to inflammation (mg/ml) (high value means high risk of inflammation)

Alanine transaminase12 weeks

Alanine transaminase refers to liver function (U/L)

Blood urea nitrogen12 weeks

Blood urea nitrogen refers to renal function (mg/dl)

Modified Medical Research Council Dyspnea Score12 weeks

Modified Medical Research Council Dyspnea Score shows in dyspnea score (score 0 to 4 means low dyspnea to high severity).

Tumor necrosis factor alpha12 weeks

Tumor necrosis factor alpha is a pro-inflammatory cytokine (picogram/ml) (high value means high risk of inflammation)

Alkaline phosphatase12 weeks

Alkaline phosphatase refers to liver function (U/L)
