Summary

COVID-19 has spread rapidly and now affects all over the world. On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a global pandemic by the World Health Organization (WHO).

Most of the infected people will develop mild to moderate illness, for example fever, cough, tiredness and joint pain etc. For some older people, and those with comorbidities like cardiovascular disease, diabetes, chronic respiratory disease, and malignancy are more likely to develop serious illness. Also long-term problems such as fatigue, breathlessness and joint pain experienced by survivors of COVID-19 after discharge from hospital.

Some clinical and pharmacological studies have suggested Traditional Chinese Medicine (TCM) has achieved remarkable therapeutic effect for active COVID cases of different severity during SARS epidemic in 2003. Also, some studies shown that using Chinese medicine interventions together with conventional treatment is more effective than using the conventional treatment alone in treating chronic fatigue syndrome.

Traditional Chinese Medicine (TCM) has a long history and played an important role in the prevention and treatment of several epidemic diseases. However, there is a lack of clinical study of using TCM to treat the residue symptom of COVID-19 recovered patients.

COVID-19 recovered patients will be screened and randomized into TCM group or placebo group for 8 weeks and followed by a post-treatment visits at week 12.

Description

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases. A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. COVID-19 has spread rapidly and now affects all over the world. As of 31 Jan 2021, over 100 million COVID-19 confirmed cases were reported worldwide, with more than 2 million related death.

Up to now, most frequently used therapies are corticosteroids, antiviral agents, antiviral/immunomodulatory drugs, serotherapy, anticoagulant and inflammation inhibitors. Recent studies reported that different kinds of residue symptoms were left after patient discharged from the hospital, such as fatigue, breathlessness and joint pain.

During SARS epidemic in 2003, the treatment of Traditional Chinese Medicine (TCM) has achieved remarkable therapeutic effect. Many different types of TCM have been proposed to treat COVID-19, of which the most famous are "three medicines and three formulae": Jinhua Qinggan Granule, Lianhua Qingwen Capsule/Granule, Xuebijing Injection; Lung Cleansing and Detoxifying Decoction, HuaShiBaiDu Formula and XuanFeiBaiDu Formula, which are mainly used for active COVID cases of different severity. Clinical and pharmacological studies have suggested their efficacy, safety and possible mechanisms in treating different stages of COVID-19, either used along with conventional treatment or independently.

For residual symptoms seen in COVID recovered patients, such as fatigue, dyspnoeaand insomnia, there are also studies suggesting that TCM may be helpful. Some studies shown that using Chinese medicine interventions together with conventional treatment is more effective than using the conventional treatment alone in treating chronic fatigue syndrome.

Liujunzhi Decoction (LJZD) and Shashen Maidong Decoction (SSMDD) are classic Chinese medicine formulae that have been used in China for hundreds of years. Their combination is proposed as the intervention of this trial because, from the perspective of Chinese medicine, the residual symptoms of COVID-19 can often be seen as the manifestation of "lung-spleen qi deficiency" or "qi and yin deficiency". ModifiedLJZD and SSMDD are the two most frequently recommended formulae versions in the recovery stage of COVID-19. This study is to evaluate the efficacy of using COVID Rehab Formula "CRF"(LJZD and SSMDD with variations) on the residue symptom of COVID-19 recovered subjects. To evaluate the efficacy of using COVID Rehab Formula "CRF" on the residue symptom of COVID-19 recovered subjects. COVID-19 recovered patients will be randomly assigned to TCM group or placebo group for study treatment 8 weeks and followed by a post-treatment visits at week 12.
