Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Participants will be the patients aged 18-65 years old who have been previously diagnosed to be infected with COVID-19 and discharged from local hospitals after treatment with western medicines, and with negative results from COVID-19 virus detection. The subjects will be evaluated for potential pulmonary fibrosis and those who present with the condition resulting from COVID-19 infection will be included.
Exclusion Criteria:
- Participants will be excluded if they have one or more of the followings: 1) inability to communicate (e.g. cognitive impairment); 2) history of Chinese medicine allergies; 3) incompetent in giving consent.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Resveratrol group
Resveratrol group (treatment group) will be instructed to consume with capsules (1.0 g, orally once a day) for six months.
|
Resveratrol has been used as a food supplement.
Its antiviral properties have been well studied including its inhibitory effect against the coronavirus MERS-CoV.
Our previous in vitro and in vivo studies found that the compound had other health benefits such as anti-fibrotic effect.The anti-fibrotic effect will add an extra benefit for resveratrol to fight against COVID-19 as lungs are the most affected organs by the coronavirus, which may result in prolonged fibrotic damage of the lungs even when a patient is recovered from the COVID-19 disease.

PLACEBO_COMPARATOR: Placebo group
Placebo group (control group) will be instructed to orally take placebo (edible paraffin, 1.0) once a day.
|
The placebo consist of mainly starch and microcrystalline cellulose, the usage and dosage are the same as the investigational drug.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The handheld basic spirometry
Time Frame: 9 months
|
Lung function will be assessed by the handheld basic spirometry (forced expiratory volume, FEV and forced vital capacity, FVC).
FEV is the parameter to measure how much air the participants can force from their lungs in one second.
Lower FEV-1 readings indicate more significant obstruction.
FVC is the largest amount of air that the participants can forcefully exhale after breathing in as deeply as they can.
A lower than normal FVC reading indicates restricted breathing.
The participants will be trained to check these measurements at home and record the data in the patient diary.
|
9 months
|
PRO scores
Time Frame: 9 months
|
All the symptoms will be measured by PRO scores according to the clinical symptoms of COVID-19 rehabilitation patients.
The scores will be ranged from 0-4: "0" indicates none; "1" indicates mild; "2" indicates moderate; "3" indicates moderately severe; and '4" indicates severe.

Borg Category-Ratio 0-10 Scale
Time Frame: 9 months
|
We will also use Borg Category-Ratio 0-10 Scale (Borg CR10 Scale) to measure dyspnea as recommended by the American College of Sports Medicine (ACSM) guidelines for patients with pulmonary diseases (Asha et al., 2012). The Borg Category Ratio 10 (CR10) Scale® (Borg Dyspnea Scale), will be used to rate the patients' dyspnea and overall fatigue level. Scale: 0=Rest; 0.5=Really Really Easy; 1=Really Easy; 2=Easy; 3=Moderate; 4=Sort of Hard; 5,6=Hard; 7,8,9=Really Hard; 10=Maximal |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Lung Function Questionnaire with 6-min walk-test
Time Frame: 9 months
|
Lung Function Questionnaire is a simple, brief, self-administered instrument to identify patients appropriate for lung function evaluation by 5 items about the breathing problems and/or frequent cough.
It was validated in Chinese and widely used in primary care (Hanania et al., 2010).
|
9 months
|
the World Health Organization Quality of Life Brief Assessment [WHOQOL-BREF (HK)]
Time Frame: 9 months
|
WHOQOL-BREF (HK) (Leung, K F., et al., 2005) was validated in Hong Kong and widely use in academia and clinicians since 1997.
This is a 5-point Likert scale with a total of 28 Questions to identify the perceived QOL of the participants.
There are four domains namely Physical Health, Psychological, Social and Environment domains with a maximum of 100.

Body constitution questionnaires
Time Frame: 9 months
|
In 2009, the classification of body constitutions into nine specific types has been recognized by China Association of Chinese Medicine as the standard of body constitution (China Association of Chinese Medicine, 2009).
Our research team also validated this questionnaire in Cantonese.
The related version of questionnaire will be applied in this study.
It is a self-rating scale with good reliability and validity.
It contains nine subscales: gentleness, qi-deficiency, yang-deficiency, yin-deficiency, phlegm-dampness, dampness-heat, blood-stasis, qi-depression, and special diathesis.
Score of each subscale is standardized from 0 to 100.
Gentleness type is a balanced one with higher score indicating a better constitution status, while the other eight types are pathological types with higher score indicating worse constitution status.
