An Open-Label, Pilot Trial of HRG80™ Red Ginseng in Chronic Fatigue Syndrome, Fibromyalgia, and Post-Viral Fatigue

Abstract:

Chronic fatigue syndrome and fibromyalgia (CFS/FMS) affect 2.1% of the world’s population and ~10–25% of people who have had COVID-19. Previous clinical data suggested that a unique Panax ginseng (C.A. Meyer, family Araliaceae) root extract (HRG80™ Red Ginseng) often resulted in marked improvement. We aimed to study this hydroponic form of red ginseng root, containing high levels of rare ginsenosides, for improving energy, cognition, and stamina. This open-label prospective study included participants with severe CFS/FMS who took a daily supplement of HRG80 capsules (200–400 mg) or tablets (100–200 mg) for one month.
A total of 188 subject patients completed the one-month treatment trial. Of these, 60.1% rated themselves as improved, with 13.3% rating themselves as being much better. In this group, the mean composite score improved from 11.9 to 18.8 (p < 0.001), with a 67% average increase in energy, 44% average increase in overall well-being, 48% average improvement in mental clarity, 58% average composite improvement in the previous three measurements (primary outcome measure), 46% average improvement in sleep, 33% average decrease in pain, and 72% average increase in stamina. Our study showed that HRG80 red ginseng root powder resulted in a marked improvement in people with CFS and fibromyalgia. This included the subgroup with post-viral CFS/FMS.

Endothelial Senescence and Chronic Fatigue Syndrome, a COVID-19 Based Hypothesis

Abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome is a serious illness of unknown etiology, characterized by debilitating exhaustion, memory impairment, pain and sleep abnormalities. Viral infections are believed to initiate the pathogenesis of this syndrome although the definite proof remains elusive. With the unfolding of COVID-19 pandemic, the interest in this condition has resurfaced as excessive tiredness, a major complaint of patients infected with the SARS-CoV-2 virus, often lingers for a long time, resulting in disability, and poor life quality.

In a previous article, we hypothesized that COVID-19-upregulated angiotensin II triggered premature endothelial cell senescence, disrupting the intestinal and blood brain barriers. Here, we hypothesize further that post-viral sequelae, including myalgic encephalomyelitis/chronic fatigue syndrome, are promoted by the gut microbes or toxin translocation from the gastrointestinal tract into other tissues, including the brain. This model is supported by the SARS-CoV-2 interaction with host proteins and bacterial lipopolysaccharide. Conversely, targeting microbial translocation and cellular senescence may ameliorate the symptoms of this disabling illness.

COVID-19 and chronic fatigue syndrome: Is the worst yet to come?

Abstract:

There has been concern about possible long-term sequelae resembling myalgic encephalomyelitis/chronic fatigue syndrome in COVID-19 patients. Clarifying the mechanisms underlying such a “post-COVID-19 fatigue syndrome” is essential for the development of preventive and early treatment methods for this syndrome.

In the present paper, by integrating insights pertaining to the glymphatic system and the nasal cerebrospinal fluid outflow pathway with findings in patients with chronic fatigue syndrome, idiopathic intracranial hypertension, and COVID-19, I provide a coherent conceptual framework for understanding the pathophysiology of post-COVID-19 fatigue syndrome. According to this hypothesis, this syndrome may result from damage to olfactory sensory neurons, causing reduced outflow of cerebrospinal fluid through the cribriform plate, and further leading to congestion of the glymphatic system with subsequent toxic build-up within the central nervous system. I further postulate that patients with post-COVID-19 fatigue syndrome may benefit from cerebrospinal fluid drainage by restoring glymphatic transport and waste removal from the brain.

Obviously, further research is required to provide further evidence for the presence of this post-viral syndrome, and to provide additional insight regarding the relative contribution of the glymphatic-lymphatic system to it. Other mechanisms may also be involved. If confirmed, the glymphatic-lymphatic system could represent a target in combating post-COVID-19 fatigue syndrome. Moreover, further research in this area could also provide new insights into the understanding of chronic fatigue syndrome.

Chronic Disease Stakeholders Join SOLVE M.E. in Push for Federally Funded Research into Long COVID

Press Release: LOS ANGELES, Dec. 4, 2020 /PRNewswire/ — Twenty leading chronic disease stakeholders joined the Solve ME/CFS Initiative (Solve M.E.) in authoring a powerful letter urging Congress to fund millions of dollars in new National Institutes of Health (NIH) and Centers for Disease Control and Prevention (CDC) research into the post-viral health complications for long-term COVID-19 (Long COVID) survivors. To view a copy of the letter, click here.

With more than 13.9 million coronavirus infections in the U.S., the letter emphasizes the importance of research into chronic conditions known to be associated with viral triggers, such as: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), Dysautonomia, Mast Cell Activation Syndrome (MCAS), and Postural Orthostatic Tachycardia Syndrome (POTS), among others. Authors of the letter include: Solve ME/CFS Initiative, National Health Council, National Organization for Women, #MEAction, Open Medicine Foundation, Dysautonomia International, The Mast Cell Disease Society, Body Politic, COVID-19 Longhauler Advocacy Project, Hadassah, American Medical Women’s Association, Nurse Practitioners in Women’s Health, HealthyWomen, Bateman-Horne Center, Institute for Neuro-immune Medicine, Pandora.Org, Sex and Gender Health Collaborative, Minnesota ME/CFS Alliance, The Shane Foundation, Massachusetts ME/CFS & FM Association, & The American Dysautonomia Institute.

Letter serves as a warning about the increasing number of COVID-19 patients experiencing post-viral complications.

“Preliminary evidence suggests that nearly five million Americans will experience Long COVID regardless of infection severity, which will likely result in a post-viral chronic fatigue crisis,” said Oved Amitay, CEO of Solve M.E. “Solve M.E. and our stakeholder allies call on Congress to act now to support new NIH and CDC funding for research into the health needs of this rapidly growing patient population.”

The letter cites warnings from leading public health officials — including Dr. Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases — about the estimated 3.2 million Americans that could be temporarily or permanently disabled by Long COVID symptoms. Indeed, studies show that 66 percent of patients with post-viral acute respiratory distress syndrome report experiencing severe fatigue after 12 months, consistent with Dr. Fauci’s analysis that Long COVID symptoms are “highly suggestive” of ME/CFS. These alarming statistics underscore the urgent need for funding, research, diagnostics, and treatment into Long COVID.

Chronic disease experts unanimously agree that in order to adequately address Long COVID complications, Congress must act immediately and appropriate the following funds:

$110 million for the establishment of Long COVID Collaborative Research Centers and Centers of Excellence;
$60 million toward expanding post-viral disease research;
$3.5 million for the development and issuance of medical guidance about Long COVID to medical providers and front-line health professionals; and
$300,000 toward convening experts and stakeholders to establish data harmonization.

“We strongly encourage these funds be allocated to the NIH and CDC by way of the congressional appropriations process or a future COVID-19 relief package so this critically important research can begin immediately,” said Amitay.

The occupational and quality of life consequences of chronic fatigue syndrome/myalgic encephalomyelitis in young people

Abstract:

INTRODUCTION: Chronic fatigue syndrome, termed myalgic encephalomyelitis in the United Kingdom (CFS/ME), is a debilitating condition involving severe exhaustion, cognitive difficulties, educational and vocational losses, and disruption of social activities and relationships. CFS/ME may affect volition (that is, value, interest and sense of competence).

PURPOSE: To test Model of Human Occupation (MOHO) concepts by comparing young people with and without CFS/ME in terms of occupational participation, volition and health-related quality of life during infection and over time.

METHOD: Three hundred and one people (12-18 years old) diagnosed with glandular fever were evaluated at the time of acute infection (baseline). Six months following diagnosis, 39 of them met the criteria for CFS/ME. A further 39 who recovered were randomly selected and matched to CFS/ME participants. Both groups were re-evaluated at 12 months and 24 months. The Occupational Self Assessment and the Child General Health Questionnaire were used to compare occupational participation.

RESULTS: Those with CFS/ME reported lower levels of perceived competency, more difficulties with physical functioning and poorer general health status than those who recovered.

CONCLUSION: Those with CFS/ME report lower perceived competency, and compromises in physical functioning, school performance, social activities, emotional functioning and general health. This supports the MOHO assertion that impairments affect volition and quality of life.

Chronic widespread musculoskeletal pain, fatigue, depression and disordered sleep in chronic post-SARS syndrome; a case-controlled study

Abstract:

BACKGROUND: The long term adverse effects of Severe Acute Respiratory Syndrome (SARS), a viral disease, are poorly understood.

METHODS: Sleep physiology, somatic and mood symptoms of 22 Toronto subjects, 21 of whom were healthcare workers, (19 females, 3 males, mean age 46.29 yrs.+/- 11.02) who remained unable to return to their former occupation (mean 19.8 months, range: 13 to 36 months following SARS) were compared to 7 healthy female subjects. Because of their clinical similarities to patients with fibromyalgia syndrome (FMS) these post-SARS subjects were similarly compared to 21 drug free female patients, (mean age 42.4 +/- 11.8 yrs.) who fulfilled criteria for fibromyalgia.

RESULTS: Chronic post-SARS is characterized by persistent fatigue, diffuse myalgia, weakness, depression, and nonrestorative sleep with associated REM-related apneas/hypopneas, an elevated sleep EEG cyclical alternating pattern, and alpha EEG sleep anomaly. Post- SARS patients had symptoms of pre and post-sleep fatigue and post sleep sleepiness that were similar to the symptoms of patients with FMS, and similar to symptoms of patients with chronic fatigue syndrome. Both post-SARS and FMS groups had sleep instability as indicated by the high sleep EEG cyclical alternating pattern rate. The post-SARS group had a lower rating of the alpha EEG sleep anomaly as compared to the FMS patients. The post-SARS group also reported less pre-sleep and post-sleep musculoskeletal pain symptoms.

CONCLUSIONS: The clinical and sleep features of chronic post-SARS form a syndrome of chronic fatigue, pain, weakness, depression and sleep disturbance, which overlaps with the clinical and sleep features of FMS and chronic fatigue syndrome.

Serum Cytokine Levels in Postinfective Fatigue Syndrome

TO THE EDITOR—Previous studies have sought evidence for a role of abnormal cytokine activity in patients with chronic fatigue syndrome and have had conflicting results [1–3]. These ambiguous results may reflect heterogeneity in groups of patients considered to have chronic fatigue syndrome and variations in assay systems.

We established postinfective fatigue syndrome as the only well-characterized model of the onset and evolution of chronic fatigue syndrome in a prospective cohort of individuals followed up from the onset of acute infection (Dubbo Infection Outcomes Study [DIOS]) [4]. Longitudinally collected clinical data and blood samples from participants in DIOS provide a unique opportunity for nested case-control studies examining the pathophysiology of chronic fatigue syndrome.

We previously reported the lack of association between cytokine production from cultured peripheral blood mononuclear cells and the postinfective fatigue syndrome- related illness in participants in DIOS [5]. We now report a masked analysis of a longitudinal case-control series from DIOS that extended the number of cytokines tested and focused on serum levels.

Twenty patients with acute infection were selected, including 5 patients with serologically confirmed acute Epstein-Barr virus (EBV) infection followed by postinfective fatigue syndrome lasting ⩾6 months, 5 patients with acute infection (not primary EBV but seropositive for EBV) followed by postinfective fatigue syndrome, and 10 matched control subjects with acute EBV infection followed by prompt recovery. Serum samples and clinical data from baseline and from 3–6 months and 9–12 months after onset of infection were analyzed. Serum samples were coded according to case-control status before transfer to the cytokine analysis laboratory.

Thirty-five analytes were measured in serum samples with use of amultiplex immunoassay, including the chemokines leptin, epithelial cell-derived neutrophil-activating peptide 78, eotaxin, growth-regulated oncogene α, interleukin (IL)-8, interferon (IFN)-inducible protein 10, monocyte chemotactic protein 3, monokine induced by gamma IFN, macrophage inflammatory protein 1α, macrophage inflammatory protein 1β, and regulated upon activation normal T cell expressed and secreted; the cytokines IFN-γ, IL-1α, IL-1β, IL-1Ra, IL-4, IL-5, IL-6, IL-7, IL-2, IL-10, IL-12p40, IL-12p70, IL-13, IL-15, IL-17, IL-17F, tumor necrosis factor α, tumor necrosis factor β; and the growth factors nerve growth factor, plate-let-derived growth factor β, transforming growth factor β, vascular endothelial growth factor, fibroblast growth factor β, granulocyte colony-stimulating factor, and granulocyte-macrophage colony-stimulating factor.

All of the study groups were predominantly female and were matched for both sex distribution (by χ2 test, P = .670) and age (by analysis of variance, P = .597). Cytokine data were analyzed by 2-way analysis of variance examining the effects of time and type of case (EBV postinfective fatigue syndrome, non-EBV postinfective fatigue syndrome, or control) and by Spearman’s correlation between symptom scores and cytokine levels. Because of the number of parameters tested, a conservative threshold for statistical significance (P < .005) was used. Results are shown in Table 1

Chronic fatigue syndrome after infectious mononucleosis in adolescents

Abstract:

OBJECTIVE: The goal was to characterize prospectively the course and outcome of chronic fatigue syndrome in adolescents during a 2-year period after infectious mononucleosis.

METHODS: A total of 301 adolescents (12-18 years of age) with infectious mononucleosis were identified and screened for nonrecovery 6 months after infectious mononucleosis by using a telephone screening interview. Nonrecovered adolescents underwent a medical evaluation, with follow-up screening 12 and 24 months after infectious mononucleosis. After blind review, final diagnoses of chronic fatigue syndrome at 6, 12, and 24 months were made by using established pediatric criteria.

RESULTS: Six, 12, and 24 months after infectious mononucleosis, 13%, 7%, and 4% of adolescents, respectively, met the criteria for chronic fatigue syndrome. Most individuals recovered with time; only 2 adolescents with chronic fatigue syndrome at 24 months seemed to have recovered or had an explanation for chronic fatigue at 12 months but then were reclassified as having chronic fatigue syndrome at 24 months. All 13 adolescents with chronic fatigue syndrome 24 months after infectious mononucleosis were female and, on average, they reported greater fatigue severity at 12 months. Reported use of steroid therapy during the acute phase of infectious mononucleosis did not increase the risk of developing chronic fatigue syndrome.

CONCLUSIONS: Infectious mononucleosis may be a risk factor for chronic fatigue syndrome in adolescents. Female gender and greater fatigue severity, but not reported steroid use during the acute illness, were associated with the development of chronic fatigue syndrome in adolescents. Additional research is needed to determine other predictors of persistent fatigue after infectious mononucleosis.

Neuropsychiatric sequelae of Nipah virus encephalitis

Abstract:

The authors followed nine patients with Nipah virus encephalitis over the course of 24 months. Eight of the nine developed psychiatric features assigned to the encephalitis. Three patients developed major depressive disorder immediately after recovering from the encephalitis, and two developed depression approximately 1 year after the outbreak. Two patients developed personality changes, and two suffered chronic fatigue syndrome.

Neuropsychological testing was accomplished in eight of the nine patients. Deficits in attention, verbal, and/or visual memory were substantial in seven of the eight patients tested. Verbal memory was more impaired than visual memory in these patients. Comparison between psychiatric and cognitive impairment and total number of brain lesions showed no discernible trends.

Recovery from infectious mononucleosis: a case for more than symptomatic therapy? A systematic review

Abstract:

Infectious mononucleosis is usually an acute, transiently incapacitating condition, but for some sufferers it precipitates chronic illness. It is unclear which patients are at risk of a prolonged state of illness following onset of infectious mononucleosis and if there are any useful preventive measures that would facilitate recovery. The aim of this study was to review all cohort studies and intervention trials that provide information on: (a) the longitudinal course of ill health subsequent to the onset of infectious mononucleosis; (b) the relationship between psychosocial and clinical factors and recovery rate; and (c) the effect of interventions on recovery.

A systematic review was conducted, based on a search of the PSYCHINFO, MEDLINE, EMBASE and CINHAL databases up to October 2001, and ISI Science and Social Sciences Citation Indices up to 22 November 2001. Eight papers were identified that gave data on illness following onset of infectious mononucleosis. The best evidence concluded that there is a distinct fatigue syndrome after infectious mononucleosis. Eight papers explored risk factors for prolonged illness following acute infectious mononucleosis.

Results varied on the association of acute illness characteristics and psychological features with prolonged ill health. Poor physical functioning, namely lengthy convalescence and being less fit or active, consistently predicted chronic ill health. Three trials reported on interventions that aimed to shorten the time taken to resolve symptoms after uncomplicated infectious mononucleosis. None of the drug trials found any evidence that drug therapy shortens recovery time. The trial that compared the effect of activity with imposed bed rest, found that those patients allowed out of bed as soon as they felt able reported a quicker recovery. More information is needed on the course of ill health subsequent to the onset of infectious mononucleosis. Certain risk factors associated with delay may be amenable to a simple intervention in primary care.
