Complementary and Alternative Medicine for Long COVID: Scoping Review and Bibliometric Analysis

Abstract:

Prolonged symptoms after the clearance of acute coronavirus disease 2019 (COVID-19) infection, termed long COVID, are an emerging threat to the post-COVID-19 era. Complementary and alternative medicine (CAM) interventions may play a significant role in the management of long COVID. The present study aimed to identify published studies on the use of CAM interventions for long COVID and provide an overview of the research status using bibliometric analysis.

The present scoping review searched MEDLINE, Embase, and Cochrane Library from inception until November 2021 and identified published studies on CAM interventions for long COVID. A narrative analysis of the study types and effectiveness and safety of the CAM interventions are presented and a bibliometric analysis of citation information and references of the included publications were analyzed using the Bibliometrix package for R. An electronic database search identified 16 publications (2 clinical studies and 14 study protocols of systematic reviews or clinical studies) that were included in the present study. Dyspnea or pulmonary dysfunction, quality of life, olfactory dysfunction, and psychological symptoms after COVID-19 infection were assessed in the included publications.

The two clinical studies suggested that Chinese herbal medications were effective in relieving symptoms of pulmonary dysfunction. Bibliometric analysis revealed the current trend of research publication in this area was driven by study protocols written by Chinese, Korean, and Indian authors. Thus, the present scoping review and bibliometric analysis revealed that there are few studies published about the use of CAM for long COVID and long-term management for COVID-19 survivors. Original studies on CAM interventions, including randomized controlled trials and systematic reviews, are required to actively support evidence for their use in the management of long COVID. PROSPERO registration: this trial is registered with CRD42021281526.

Mechanism of acupuncture and moxibustion in treatment of chronic fatigue syndrome from perspective of intestinal flora

Abstract:

Intestinal flora dysbiosis may play an important role in the occurrence and development of chronic fatigue syndrome (CFS), which may induce the inflammatory response and metabolic disturbance of patients with CFS. Acupuncture and moxibustion may achieve anti-fatigue effect by affecting the diversity and quantity of intestinal flora, improving intestinal barrier function, and regulating brain-gut peptides.

Effects of the Prolong Life With Nine Turn Method (Yan Nian Jiu Zhuan) Qigong on Brain Functional Changes in Patients With Chronic Fatigue Syndrome in Terms of Fatigue and Quality of Life

Abstract:

Background: Chronic fatigue syndrome (CFS) is characterized by persistent fatigue, which often leads to physical and psychological damage. The Prolong Life with Nine Turn method (PLWNT) Qigong is considered as one of the complementary treatments for improving symptoms in patients with CFS. In this study, we used functional magnetic resonance imaging (fMRI) to explore the effects of PLWNT intervention on the subjects with CFS.

Methods: Thirty four CFS patients were randomly divided into PLWNT group and cognitive behavioral therapy (CBT) group. Both groups were taught by a highly qualified professor at the Shanghai University of Traditional Chinese Medicine once a week and were supervised online during the remaining 6 days at home, over 12 consecutive weeks. We calculated the regional rs-fMRI index amplitude of low-frequency fluctuations (ALFF) for all subjects. To study the changes of the brain network, we used the brain regions with significant differences in ALFF as the regions of interest for whole-brain functional connectivity (FC) analysis. The Multi-dimensional Fatigue Inventory 20 (MFI-20) and Short Form 36-item Health Survey (SF-36) were used for clinical symptom assessment to explore the possible correlation between the rs-fMRI indicators and clinical variations.

Results: The ALFF values of the right superior frontal gyrus (SFG), and left median cingulate gyrus (DCG) were increased, whereas those of the left middle occipital gyrus (OG), right middle OG and left middle temporal gyrus (MTG) were decreased in PLWNT group. The FC values between the DCG and middle temporal gyrus (MTG), and those between the left OG and the right OG were enhanced. In addition, the SF-36 were positively with the left OG (r = 0.524), SFG (r = 0.517), and DCG (r = 0.533), MFI-20 were negatively with the SFG (r = -0.542) and DCG (r = -0.578). These results were all corrected by FWE (voxel level p < 0.001, cluster level p < 0.05).

Conclusion: CFS patients have abnormal regional spontaneous neuronal activity and abnormal functional connections between regions after PLWNT intervention. PLWNT can relieve the fatigue symptoms of CFS patients and improve their quality of life. The study was registered in the American Clinical Trial Registry (12/04/2018). Registration Number is NCT03496961.

Improvement in Long-COVID Symptoms Using Acupuncture: A Case Study

Abstract:

Background: The long-COVID syndrome (LCS), defined by residual symptoms from acute COVID-19 for <60 days, affects about one-third of all COVID survivors and is an emerging public health challenge. Empirical data about the range of symptoms or the utility of acupuncture alone for the LCS are very limited.

Case: This observational case study of a 46-year-old male with LCS was conducted to preliminarily define the range of symptoms, a Traditional Chinese Medicine (TCM) diagnostic structure, and evaluate the potential utility of prescribed acupuncture for LCS.

Results: The primary TCM diagnostic patterns from this patient’s LCS presentation included Lung Qi and Yin Deficiency, Qi and Blood Stagnation, and Spleen Qi Deficiency with dampness. Acupuncture for this patient was associated with reduced symptoms and signs of LCS.

Conclusion: A preliminary TCM diagnostic structure for LCS was defined. Acupuncture appears to have been helpful for a patient with LCS. Further research is needed to demonstrate the efficacy of acupuncture and/or other TCM modalities for LCS.

The Role of Acupuncture for Long COVID: Mechanisms and Models

Abstract:

Objective: To establish an evidence-based role for acupuncture as a safe and effective treatment for managing Long COVID in the integrative medical setting.

Background: COVID-19 progresses to a chronic state, termed Long COVID, in about 30% of cases with estimates as high as 40% for prolonged illness. Symptoms are diverse and range over several body systems, including unrelenting fatigue, persistent malaise, chronic pain, and mood changes. Early clinical reports suggest acupuncture can effectively address both symptoms and the underlying causes of Long COVID.

Evidence: Historically, acupuncture is well defined in Traditional Chinese Medicine writings to treat influenza-like febrile illnesses. Contemporary scientific literature and case studies support the value of acupuncture for symptoms associated with acute and chronic respiratory viral infections, such as influenza, including SARS and COVID-19. Recent reports provide early evidence of acupuncture’s effectiveness in managing Long COVID symptoms and may also have disease-modifying benefits.

Conclusion: Acupuncture is a viable adjunctive health care modality as part of a multidisciplinary approach for symptom control and disease management to improve quality of life in Long COVID patients. Since acupuncture may favorably modify the length and outcome of this condition, the model of acupuncture presented in this article warrants broader use in the integrative clinical setting and for further research.

Conceptualizing a Traditional Chinese Medicine and Pathology of Arousal Diagnostic and Pathophysiological Framework for Postacute Sequelae of COVID-19

Abstract:

Introduction: The postacute sequelae of COVID-19 (PASC) is a serious heterogeneous condition that affects a significant minority of those who endured COVID-19. PASC involves multiple body systems and an illness trajectory that has stages now being identified in medical research.

Objective: Traditional Chinese Medicine (TCM) and acupuncture are well suited to conceptualize and treat PASC and other postviral conditions. No description of TCM theory and its relationship with modern medical theory about PASC and its illness trajectory currently exists.

Conclusion: The authors provide an overview of the potential value of TCM for conceptualizing and treating PASC with a few examples and clarify directions for research.

The Qigong of Prolong Life With Nine Turn Method Relieve Fatigue, Sleep, Anxiety and Depression in Patients With Chronic Fatigue Syndrome: A Randomized Controlled Clinical Study

Abstract

Background: Chronic fatigue syndrome (CFS) is a complex disease of unknown etiology and mechanism. The purpose of this study was to investigate the effect of Prolong Life with Nine Turn Method (PLWNT) Qigong exercise on CFS focusing on fatigue, sleep quality, depression, and anxiety.

Methods: A total of 90 participants diagnosed with CFS were randomly assigned into two parallel groups: PLWNT and cognitive behavioral therapy (CBT). The participants in the PLWNT or CBT group participated in qigong exercise or cognitive behavior education program, respectively, once a week in-person and were supervised online during the remaining 6 days at home, over 12 consecutive weeks. The primary outcome was fatigue (Multi-dimensional Fatigue Inventory 20 [MFI-20]), and secondary outcomes were sleep quality (Pittsburgh Sleep Quality Index [PSQI]), anxiety, depression (Hospital Anxiety and Depression Scale [HADS]), and changes in the Neuropeptide Y (NPY) of peripheral blood.

Results: The within-group comparisons of the PLWNT and CBT groups revealed significant improvement in both groups in MFI-20, PSQI, and HADS scores (P < 0.05). No significant difference were found between the PLWNT and CBT groups, even though the effective rate of the PLWNT group was 62.22%, which is slightly than 50.00% of the CBT group. The fatigue scores in the PLWNT group were positively correlated with sleep degree (r = 0.315) and anxiety degree (r = 0.333), only anxiety degree (r = 0.332) was found to be positively correlated with fatigue in the CBT group. The analysis of peripheral blood showed that NPY decreased after PLWNT intervention but increased significantly in the CBT.

Conclusion: The PLWNT qigong exercise has potential to be an effective rehabilitation method for CFS symptoms including fatigue, sleep disturbance, anxiety, and depression. Future studies should expand study sample size for in-depth investigation to determine the optimal frequency and intensity of PLWNT qigong intervention in CFS patients. The study was registered in the ClinicalTrials.gov database on April 12, 2018, with registration number NCT03496961.

Dietary supplements, daily nutrient intake, and health-related quality of life among people with myalgic encephalomyelitis/chronic fatigue syndrome

There remains ambiguity surrounding the role of dietary supplementation and nutrient intake on the health status of myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) patients, yet supplement use and dietary modification appear to be common among people with the condition. This pilot cross-sectional study aimed to investigate if supplement use or nutrient intake was associated with self-reported health-related quality of life (HRQoL) scores among Australians with ME/CFS.

The eligibility criteria for this study included being a resident of Australia, being aged between 18 and 65 years, and having received a formal diagnosis of ME/CFS from a physician. Participants completed a series of self-administered questionnaires querying sociodemographic information, symptom presentation, HRQoL, routine supplement use, and nutrient intake. The 36-item Short-Form Health Survey version 2 (SF-36) was employed to assess participants’ HRQoL. Daily nutrient intake was estimated from participants’ responses to the Dietary Questionnaire for Epidemiological Studies (Cancer Council Victoria, Australia). Multiple linear regression analysis was performed for each of the eight SF-36 domains. Age, gender, body mass index, employment, education were controlled variables in each model, with supplement and nutrient variables entered in a stepwise manner.

Twenty-four Australians with ME/CFS, 54.2% of which met the International Consensus Criteria case definition for ME/CFS, participated in the study. Three of the eight regression models were statistically significant, being the ‘role limitations due to physical health problems’ (adjusted R 2 = 0.733, P < 0.001), ‘bodily pain’ (adjusted R 2 = 0.544, P = 0.004), and ‘general health perceptions’ (adjusted R 2 = 0.743, P < 0.001) SF-36 domains. Positive associations were observed between HRQoL and the routine use of vitamin C (ß = 0.300, P = 0.042) and herbal supplements (ß = 0.618, P < 0.001), as well as daily saturated fat (ß = 0.860, P < 0.001), total folate (ß = 0.710, P < 0.001), and calcium intake (ß = 0.897, P = 0.003). However, the routine use of evening primrose oil supplements (ß = -0.385, P = 0.006) and daily intakes of alpha-linolenic acid (ß = −0.543, P = 0.001), long chain omega-3 fatty acids (ß = −0.431, P = 0.017), and iodine (ß = −0.602, P = 0.034) were negatively associated with HRQoL scores. None of the supplements or nutrients studied had consistent associations with HRQoL across the three significant regression models.

The findings of this pilot study suggest that there may be links between dietary supplementation and nutrient intake with HRQoL among people with ME/CFS. Future studies should investigate supplement use, daily nutrient intake, and their relationships with HRQoL and symptom presentation among people with ME/CFS longitudinally and compared with healthy controls to further elucidate the role of supplements and nutrient intake in the management of ME/CFS.

Semen raphani weakened the action of ginseng under chronic fatigue condition

Abstract:

Ethnopharmacological relevance: Fatigue is a kind of subhealth status and people paid much more attention on it. Ginseng is used to treating fatigue as a kind of qi -tonifying drug in Chinese medicine. In the traditional applications, there is a viewpoint that ginseng could not be used with semen raphani and supposed that semen raphani is a kind of qi regulating drug, which will reduce the qi invigorating effect of ginseng. However, the underlying combination mechanism of the two drugs remained unclear.

Aim of the study: The aim of this study is to explore whether ginseng can be used with semen raphani or not to remedy acute and chronic fatigue conditions.

Methods: We used normal and weight-bearing swimming method combined with appetite control animals. The biochemical indexes in energy metabolism, antioxidant, regulating endocrine system and immunity capacities were performed to explore the antagonism effect of semen raphani on ginseng under acute and chronic fatigue conditions. The serum and urine metabolomics were investigated using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF/MS). Fecal flora was analyzed via 16S rRNA amplicon sequencing.

Results: The combination of ginseng with semen raphani have no influence on acute fatigue effect compared with ginseng alone. Both can improve the exhausted swimming time, the activity of GSH-Px, LDH and Na+-K+-ATPase. Furthermore, the combination of ginseng with semen raphani can increase the urine volume of rats and down-regulate the content of AQP-3, which can alleviate the “fireness” side-effect of ginseng. But the abundance and diversity of bacterial are decreased under acute fatigue experiment. Both the combination of ginseng with semen raphani and ginseng alone can remedy chronic-fatigue. They can also regulate the endocrine system, immune system, citric acid cycle metabolism, tryptophan metabolism, fatty acid metabolism, glycolysis/gluconeogenesis, etc. Furthermore, they can promote substance metabolism and energy metabolism in qi deficiency rats, and increase the abundance and diversities of the flora. While with the increased content of semen raphani, the combination of ginseng and semen raphani weaken the capacity of antioxidant, lactic acid metabolism, energy metabolism, flora diversity and regulation of endocrine system.

Conclusion: Compared with ginseng alone, the combination of ginseng with semen raphani can weaken the qi invigorating ability under chronic fatigue condition. The more ratios of semen raphani is in the combination of the two drugs, the less the power of treating chronic fatigue is. Compared with ginseng alone, the combination of ginseng with semen raphani have no influence on the qi invigorating ability under actue fatigue experiment. But the combination of ginseng with semen raphani will benefit for the “fireness” side-effect of ginseng.
