Intracellular Nutritional Biomarker Differences in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Subjects and Healthy Controls

Abstract:

Objectives

A comparison of the nutritional biomarkers between ME/CFS subjects and healthy controls (HC) was undertaken on secondary data collected from an IRB approved cross-sectional study in ME/CFS patients.

Methods

ME/CFS participants were recruited per the 2018 revised Canadian Clinical Case Definition for ME/CFS along with age matched HCs. Self-reported information on demographics and supplement use was collected, and body mass index calculated. HEI was calculated from Willet FFQ and multiple day 24-hour recall data, and severity of fatigue measured by Multidimensional Fatigue Inventory (MFI). Lymphocyte transformation assay by SpectraCell Lab (Houston, TX) was employed for intracellular micronutrient status. A series of two-tailed Mann-Whitney U tests (ɑ = 0.05) were performed for the non-parametric data expressed as mean ± standard error of the mean. All statistical analyses were conducted in IBM SPSS Statistics version 25 (Armonk, NY).

Results

Out of the 21 participants (11 ME/CFS and 10 HC), 82% of ME/CFS and 50% of HC were female. Higher fatigue scores were observed in ME/CFS (16.64 ± 1.36) than HC (10.78 ± 2.14). ME/CFS had better HEI scores (63.36 ± 13.44) than the HC (38.55 ± 12.29). However, despite better diet quality and supplementation, ME/CFS group showed lower intracellular Vitamin B3 and manganese (Mn) (86.3 ± 2.42 and 53.6 ± 2.81 respectively) but higher calcium (Ca) (57.5 ± 3.55) as compared to HC (97.2 ± 2.31, 64.5 ± 1.87 and 46.5 ± 0.96 respectively).

Conclusions

The results align with the current literature on indications of mitochondrial dysfunction in ME/CFS. Reduced intracellular vit B3 provides suboptimal production of the NAD(P)(H)-cofactor family, thus affecting mitochondrial function and consequently energy production. The aberration in energy metabolism is compounded by other factors, such as reduced Mn but higher Ca intracellular levels seen in this study indicating disruptions in oxidative stress pathways, resulting in debilitating fatigue experienced by individuals with ME/CFS.

Dietary Recommendations for Post-COVID-19 Syndrome

Abstract:

At the beginning of the coronavirus disease (COVID-19) pandemic, global efforts focused on containing the spread of the virus and avoiding contagion. Currently, it is evident that health professionals should deal with the overall health status of COVID-19 survivors. Indeed, novel findings have identified post-COVID-19 syndrome, which is characterized by malnutrition, loss of fat-free mass, and low-grade inflammation. In addition, the recovery might be complicated by persistent functional impairment (i.e., fatigue and muscle weakness, dysphagia, appetite loss, and taste/smell alterations) as well as psychological distress.

Therefore, the appropriate evaluation of nutritional status (assessment of dietary intake, anthropometrics, and body composition) is one of the pillars in the management of these patients. On the other hand, personalized dietary recommendations represent the best strategy to ensure recovery. Therefore, this review aimed to collect available evidence on the role of nutrients and their supplementation in post-COVID-19 syndrome to provide a practical guideline to nutritionists to tailor dietary interventions for patients recovering from COVID-19 infections.

The Role of Nutrients in Prevention, Treatment and Post-Coronavirus Disease-2019 (COVID-19)

Abstract:

SARS-CoV-2 virus, infecting human cells via its spike protein, causes Coronavirus disease 2019 (COVID-19). COVID-19 is characterized by shortness of breath, fever, and pneumonia and is sometimes fatal. Unfortunately, to date, there is still no definite therapy to treat COVID-19. Therefore, the World Health Organization (WHO) approved only supportive care. During the COVID-19 pandemic, the need to maintain a correct intake of nutrients to support very weakened patients in overcoming disease arose. The literature available on nutrient intake for COVID-19 is mainly focused on prevention. However, the safe intake of micro- and/or macro-nutrients can be useful either for preventing infection and supporting the immune response during COVID-19, as well as in the post-acute phase, i.e., “long COVID”, that is sometimes characterized by the onset of various long lasting and disabling symptoms. The aim of this review is to focus on the role of nutrient intake during all the different phases of the disease, including prevention, the acute phase, and finally long COVID.

Role of Creatine Supplementation in Conditions Involving Mitochondrial Dysfunction: A Narrative Review

Abstract:

Creatine monohydrate (CrM) is one of the most widely used nutritional supplements among active individuals and athletes to improve high-intensity exercise performance and training adaptations. However, research suggests that CrM supplementation may also serve as a therapeutic tool in the management of some chronic and traumatic diseases. Creatine supplementation has been reported to improve high-energy phosphate availability as well as have antioxidative, neuroprotective, anti-lactatic, and calcium-homoeostatic effects. These characteristics may have a direct impact on mitochondrion’s survival and health particularly during stressful conditions such as ischemia and injury.

This narrative review discusses current scientific evidence for use or supplemental CrM as a therapeutic agent during conditions associated with mitochondrial dysfunction. Based on this analysis, it appears that CrM supplementation may have a role in improving cellular bioenergetics in several mitochondrial dysfunction-related diseases, ischemic conditions, and injury pathology and thereby could provide therapeutic benefit in the management of these conditions. However, larger clinical trials are needed to explore these potential therapeutic applications before definitive conclusions can be drawn.

Does Dietary Coenzyme Q10 plus Selenium Supplementation Ameliorate Clinical Outcomes by Modulating Oxidative Stress and Inflammation in Individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome?

Abstract:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a neuroinflammatory, multifaceted chronic disorder of unknown cause. Accumulating data indicates a link between a redox imbalance, mitochondrial dysfunction, and inflammation status in ME/CFS. CoQ10 and selenium as effective antioxidant and anti-inflammatory agents have shown potential clinical implications in chronic diseases; however, their therapeutic benefits on ME/CFS remain elusive.

This open-label exploratory study aimed to evaluate the effectiveness of combined CoQ10 plus selenium supplementation on clinical features and circulating biomarkers in ME/CFS. Twenty-seven ME/CFS patients received an oral combination of 400 mg of CoQ10 and 200 µg of selenium daily for 8-weeks. The primary endpoint was patient-reported changes in outcome measures from baseline to 8 weeks post-intervention.

Secondary endpoint included changes in circulating biomarkers from baseline to each participant. After an 8-week intervention, a significant improvement was found for overall fatigue severity (p = 0.021) and global quality of life (p = 0.002), while there was no significant effect on the sleep disturbances (p = 0.480) among participants. After 8-weeks’ intervention, there was significantly increased total antioxidant capacity, and there were reduced lipoperoxides levels from the participants (p < 0.0001 for both). Circulating cytokine levels decreased significantly (p < 0.01 for all), but with no significant changes on the CRP, FGF21, and NT-proBNP biomarkers after supplementation.

Based on these findings, we hypothesized that long-term supplementation of combined CoQ10 and selenium may indicate a potentially beneficial synergistic effect in ME/CFS.

Role of Nutritents for COVID-19 recovery: an integrative approach

Introduction: Many patients (“long-haulers”) suffer lingering illness following COVID-19. The aim of this presentation is to evaluate the evidence of nutrient deficiencies affecting immune function and chronic symptoms from covid19 infection in a subgroup of patients. We will discuss the potential benefit of supplementing with multi-nutrients as an integrative approach to reducing long-hauler symptoms.

Methods: A narrative review followed a search of Medline/Pubmed, CINAHL, Google Scholar for studies published between January 2000 and March 2021, using key terms “coronavirus”, “COVID-19”, “immune system”, “inflammation”, “microbiome”, “oxidative stress”, “mitochondrial function”, “micronutrients”, “vitamin”, “minerals”, and “antioxidants”. Six reviews were selected which examined on the role of nutrients in immune and neurological function, including inflammatory processes, microbiome homeostasis, and mitochondrial function.

Results: Symptoms of long-haulers may be similar to myalgic encephalomyelitis/chronic fatigue syndrome associated with mitochondria dysfunction due to oxidative stress. Similar findings of chronic inflammation and microbiome dysbiosis associated with mood disorders also suggest the association between nutrient deficiencies and immuno-neurological functions. Nutrients required for optimal immune function included: antioxidants such as CoQ10 is required for mitochondrial function and is depleted quickly during acute immune response. Vitamins C and E and selenium also have antioxidant properties that can decrease proinflammatory cytokines and increase leukocyte and NK cell function. The B vitamins are involved in decrease pro-inflammatory cytokines and increase NK cell activities. Similarly, these nutrients are required for optimal neurological functioning in the CNS.

Conclusion: Initial evidence suggests chronic inflammatory processes in the CNS may contribute to the symptoms of covid-19 long-haulers. Given the complementary roles of different nutrient in immune response and CNS pathways, integrating multiple nutrients as treatment for long-haulers warrants further study.

Physiological predictors of long-term effects of covid-19 in patients with sars-cov-2: focus on lymphocyte proliferation-improving micronutrients

Abstract

Patients with long-term effects of coronavirus disease, the so-called “long-term COVID-19 syndrome” (long-COVID-19) after SARS-CoV-2 infection, have a postponed recovery lasting from 4 weeks and up to six months, spread worldwide.

Physiological predictors based on human blood biomarkers and host-virus responses to SARS-CoV-2 are still unknown. There is growing evidence about the impact of micronutrients on improving lymphocyte proliferation and their essential roles for a functioning human immune system and regulating metabolic health. This paper aims to review information about micronutrients in patients with SARS-CoV-2 infection that determines long-COVID-19 outcomes and highlight the importance of diagnostics in predictors of long-COVID-19.

We reviewed articles returned from searches on PubMed/SCOPUS/Web of Science/ EMBASE databases using a combination of terms “long COVID-19”, “long-term effects of COVID-19”, “post-COVID-19 symptoms”, “COVID-19 associated stress”, “micronutrients”. Evidence indicates the relationship between lymphocyte proliferation improving micronutrient level and long-COVID-19 induction. Zinc, selenium, iron, manganese have an immunomodulatory function in innate and adaptive immune responses to viral infection. Anti-inflammatory functions of Vits A and B groups include the regulation of lymphocyte proliferation and metabolic health. Further research using sampling and artificial intelligence-assisted algorithms could assist in the recognition of the correlation of micronutrients and long-COVID-19 clinical outcomes.

Proposal of a food supplement for the management of post-COVID syndrome

Abstract:

A vast majority of COVID-19 patients experience fatigue, extreme tiredness and symptoms that persist beyond the active phase of the disease. This condition is called post-COVID syndrome. The mechanisms by which the virus causes prolonged illness are still unclear. The aim of this review is to gather information regarding post-COVID syndrome so as to highlight its etiological basis and the nutritional regimes and supplements that can mitigate, alleviate or relieve the associated chronic fatigue, gastrointestinal disorders and continuing inflammatory reactions. Naturally-occurring food supplements, such as acetyl L-carnitine, hydroxytyrosol and vitamins B, C and D hold significant promise in the management of post-COVID syndrome. In this pilot observational study, we evaluated the effect of a food supplement containing hydroxytyrosol, acetyl L-carnitine and vitamins B, C and D in improving perceived fatigue in patients who recovered from COVID-19 but had post-COVID syndrome characterized by chronic fatigue. The results suggest that the food supplement could proceed to clinical trials of its efficacy in aiding the recovery of patients with long COVID.

Boosting Health Recovery by Food Supplements: The Case of ME/CFS versus Post-Covid-19 Syndrome

Abstract:

Background and objectives: Other than the direct impact of cardiopulmonary sequelae, COVID-19 disease may cause persistent signs and symptoms describes as post-COVID syndrome or long COVID. The clinical presentation and neuroimaging aspects of patients suffering from this condition are remarkably similar to those seen in patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Inflammation, immune disorder and oxidative damage have been documented to cause metabolic deregulation with decreased glycolysis and impaired mitochondrial function.

Purpose of the study: It is suggested that these alterations may be improved by the oral administration of a nutraceutical, Meldonium and sodium dichloroacetate (group designated as “oral treatment”; n=79) or intermittent intravenous infusions of magnesium sulphate together with multivitamins and essential amino acids (group designated as “infusion treatment”, n=18).

Materials and methods: 97 patients suffering from ME/CFS (n=79) or post-COVID syndrome (n=9) were included in a pragmatic prospective open-label trial using either oral or infusion therapy for 1 month, and the effect of treatment was assessed by the Fatigue Severity Scale (FSS).

Results: Upon interim analysis of 97 cases of ME/CFS and/or Post-COVID-19 syndrome therapeutic approach by either the oral or the infusion therapy was found to result in a reduction of the Fatigue Severity Scale (FSS) in two thirds of patients. The quotient of FSS after treatment divided by the FSS before treatment decreased by an average for all 97 cases by 14% within one month, with no difference between oral and infusion therapy (P=0.70), nor between the ME/CFS patient (mean quotient: 0.85, SD: 0.16) and the post-COVID cases (quotient: 0.87, SD: 0.16). Among the successful cases the FSS decreased by an average of 31%.

Conclusion: Preliminary results of the oral and the infusion therapy suggest a similar beneficial effect on fatigue in a substantial proportion of patients suffering from ME/CFS or Post-COVID syndrome. The result should be confirmed in a controlled trial, while the long-term efficacy is presently being investigated in a larger group of patients.

Effect of Dietary Coenzyme Q10 Plus NADH Supplementation on Fatigue Perception and Health-Related Quality of Life in Individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Prospective, Randomized, Double-Blind, Placebo-Controlled Trial

Abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex, multisystem, and profoundly debilitating neuroimmune disease, probably of post-viral multifactorial etiology. Unfortunately, no accurate diagnostic or laboratory tests have been established, nor are any universally effective approved drugs currently available for its treatment. This study aimed to examine whether oral coenzyme Q10 and NADH (reduced form of nicotinamide adenine dinucleotide) co-supplementation could improve perceived fatigue, unrefreshing sleep, and health-related quality of life in ME/CFS patients.
A 12-week prospective, randomized, double-blind, placebo-controlled trial was conducted in 207 patients with ME/CFS, who were randomly allocated to one of two groups to receive either 200 mg of CoQ10 and 20 mg of NADH (n = 104) or matching placebo (n = 103) once daily. Endpoints were simultaneously evaluated at baseline, and then reassessed at 4- and 8-week treatment visits and four weeks after treatment cessation, using validated patient-reported outcome measures.
A significant reduction in cognitive fatigue perception and overall FIS-40 score (p < 0.001 and p = 0.022, respectively) and an improvement in HRQoL (health-related quality of life (SF-36)) (p < 0.05) from baseline were observed within the experimental group over time. Statistically significant differences were also shown for sleep duration at 4 weeks and habitual sleep efficiency at 8 weeks in follow-up visits from baseline within the experimental group (p = 0.018 and p = 0.038, respectively).
Overall, these findings support the use of CoQ10 plus NADH supplementation as a potentially safe therapeutic option for reducing perceived cognitive fatigue and improving the health-related quality of life in ME/CFS patients. Future interventions are needed to corroborate these clinical benefits and also explore the underlying pathomechanisms of CoQ10 and NADH administration in ME/CFS.
