Current Primary Outcome Measures ICMJE |
the change in symptom severity from 0 to 12 weeks measured by the modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm) [ Time Frame: will be assessed at baseline and 12 weeks. ] Symptom severity is one of the sub-scale of C19-YRSm. Range 0-78, with higher scores indicating greater impact of symptoms. C19-YRSm is the first validated scale describing post-COVID-19 symptoms and grading the severity of symptoms and functional disability.

Original Primary Outcome Measures ICMJE |
the self-declared modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm) [ Time Frame: will be assessed at baseline, 3 months, and 6 months. ] an ordinal patient-reported outcome measure. The scale has been recommended in NHS England Clinical Guidance for PCS services and NICE rapid guidelines. C19-YRSm is the first validated scale describing post-COVID-19 symptoms and grading the severity of symptoms and functional disability The scale's subscales include symptom severity, functional ability, other symptoms, and overall health

Brief Title ICMJE | Examining the Function of Cs4 on Post-COVID-19 Disorders | ||||
Official Title ICMJE | Examining the Immunomodulatory and Health Improving Function of a Chinese Medicine Nutritional Supplement Cs4 on Immunity-related Disorders in the Post-COVID Era | ||||
Brief Summary | Cordyceps is a medicinal Chinese medicine. The benefits of cordyceps-related therapeutic action have been studied due to its anti-inflammation and immunomodulation features. Thus, Cordyceps may have efficacy against health problems in the post-COVID era. the Cs4 is a Chinese medicine nutritional supplement fermented by Cordyceps. This Project conducts a two-stage waitlist-controlled trial to examine the therapeutic effect of the Cs4 on long-COVID patients. 110 Patients will be recruited and divided into two groups. Each group contains 55 patients. In the first-stage clinical trial for 12 weeks, group A will have treatment while group B will have no Cs4 treatment. In the second-stage clinical trial for 12 weeks, group A will have no Cs4 treatment while group B will have Cs4 treatment. A 12-week follow-up will be conducted after the intervention of Cs4 for group A. The primary outcome will be the change from 0 to 12 weeks in symptom severity measured by self-declared modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm). In our study, we intend to analyse the efficacy of Cs4 on the improvement of long Covid symptoms by using a comprehensive measurement to cover most symptoms, and be condition-specific. The secondary outcomes will include the change from 0 to 12 weeks of Insomnia Severity Index (ISI), Brief Fatigue Inventory Form, St. George's Respiratory Questionnaire (SGRQ), Hospital Anxiety and Depression Scale (HADS), and the Short Form 12 (SF12). Blood tests will be assessed for safety study. primary outcomes and secondary outcomes will be assessed at baseline (week 0) and week 12. The anticipated outcome of the study is to provide evidence of Cs4 in the improvement of long COVID symptoms. This project can serve to the development of a nutritional supplement for the management of post-COVID-related health problems. | ||||
Detailed Description | Research Methodologies Participants Setting This is a waitlist-controlled trial to examine the therapeutic effect of Cs4 on long-COVID patients, which are divided into two groups. The study will be conducted in the Specialist Clinical Centre for Teaching and Research (Sassoon Road), School of Chinese Medicine, The University of Hong Kong (HKU). Inclusion Criteria
1. Inability to read and/or write Chinese or English; 2. Inability to communicate (e.g. with cognitive impairment) 3. Allergy to Cordyceps sinensis; 4. Pregnant or lactating women; 5. Impaired hepatic or renal function. Methods Participants will be recruited through the webpage of the School of Chinese Medicine, HKU. Clinical history and comprehensive examination will be performed during the first interview by registered Chinese Medicine practitioners or registered nurses who will be informed about the aims, procedure and nature of the study, and possible side effects of Cs4 and written consent will be obtained from each subject who agrees to get into the study. The participant will be also informed that they have the freedom to withdraw at any time during the study. Study design This will be a waitlist-controlled trial in which participants will alternately receive the intervention of Cs4 for 12 weeks, followed by a 12-week follow-up. 110 long-COVID patients will be randomly divided into two groups (Group A and Group B). Randomisation will be carried out according to the computer- based Excel random number generator. An integer number between 1 and 110 will be assigned to each individual at random. Group A consists of individuals assigned integer numbers between 1 and 55. Group B consists of individuals assigned integer numbers between 56 and 110. Intervention Cs4 will be provided by Chinese Pharm, produced by GMP standard manufacturing. The intervention will be given according to the product instruction. Each capsule is 0.4g. According to the product sheet, adults should take 3-4 capsules daily as a way to nourish and strengthen the lungs and kidneys. In our study, the participants are people with long-COVID symptoms. Therefore, in order to achieve maximum efficacy, we will follow the directions and let participants take the maximum amount allowed by the product which is 4 capsules daily. Participants will take one capsule (each 400mg) 4 times a day, for a total of 1.6g. Treatment will last 12 weeks. |
