A Continuous Oral Regimen of High-Dose Cromolyn Sodium Is Effective for Some Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Patients With Mast Cell Activation Syndrome

Abstract:

Our clinical experience in the last four years using oral cromolyn in patients with mast cell activation syndrome (MCAS) suggests that a continuous oral regimen of high-dose cromolyn may enhance compliance with the medication. The five patients described in this retrospective case series were given instructions to take oral cromolyn using a continuous dosing regimen, placing the entire day’s dose in an opaque bottle that is then filled with water, and sipping the solution throughout the day. If a conventional maximum dose of eight vials daily (800 mg) was tolerated but ineffective after a week, the patients were instructed to increase to 1600-2400 mg daily until reaching an optimal effect.

We report that a cromolyn dose of 1600-2400 mg daily, administered using the continuous oral dosing regimen during the day, was effective in controlling signs and symptoms of mast cell activation. All five patients benefitted from a dose of cromolyn that is higher than usual and customary recommendations, but within the safety guidelines of the original Food and Drug Administration (FDA) application. The continuous oral regimen has some theoretical advantages over four discrete doses per day, though further study is needed.

Vitamin D in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome After COVID-19 or Vaccination: A Randomized Controlled Trial

Abstract:

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) can develop as post-vaccination syndrome (PVS) or Post-Acute Sequelae of SARS-CoV-2 infection (PASC). In our prior retrospective study, most patients with PVS who developed ME/CFS had vitamin D insufficiency or deficiency. We evaluated the efficacy of vitamin D replacement therapy guidance for ME/CFS symptom improvement in patients with vitamin D insufficiency or deficiency.

Methods: This open-label randomized controlled trial enrolled 91 participants with ME/CFS as PVS or PASC and serum 25(OH) vitamin D < 30 ng/mL across five clinical sites. Participants were randomized 1:1 to intervention (active vitamin D preparation plus vitamin D replacement therapy guidance: 25 μg daily supplementation, dietary counseling, sun exposure, and exercise) or control (active vitamin D preparation alone) for 12 weeks. The primary endpoint was the change in ME/CFS symptom count from screening to Week 12.

Results: Mean symptom change was -6.7 in the intervention group versus -1.2 in the control group (between-group difference -5.6; 95% CI: -7.2, -3.9; p < 0.001). Serum 25(OH) vitamin D improved from 18.6 to 27.1 ng/mL in the intervention group, while the control group showed a decreasing trend (between-group difference 10.2 ng/mL; 95% CI: 7.9, 12.5). Achievement of <8 symptoms (i.e., no longer meeting ME/CFS diagnostic criteria) was significantly higher in the intervention group, with 16 participants achieving this threshold compared to 1 in the control group (p < 0.001). Subgroup analyses showed consistent benefit in both PVS (n = 56) and PASC (n = 29) cohorts.

Conclusions: Vitamin D replacement therapy guidance significantly reduced ME/CFS symptoms along with improvement of serum 25(OH) vitamin D levels in patients with vitamin D insufficiency or deficiency who developed ME/CFS as PVS or PASC.

Potential application of brain-gut axis-based treatments in Long COVID and ME/CFS: a case-based systematic review

Abstract:

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and Long COVID share clinical features including persistent fatigue, post-exertional malaise (PEM), and gastrointestinal (GI) dysfunction. Growing evidence implicates brain-gut axis dysregulation, characterized by dysbiosis, neuroinflammation within the central nervous system (CNS), increased intestinal permeability, and microbial translocation in their pathophysiology. However, therapeutic strategies targeting these pathways remain poorly defined.

Methods: We report a case of post-COVID ME/CFS successfully treated with electroacupuncture (EA)-based deep peroneal nerve stimulation which was employed to potentiate the vagal reflex. Fatigue trajectories were assessed using the Multidimensional Fatigue Inventory over 12 weeks. Based on the case, a systematic review of randomized controlled trials (RCTs) evaluating brain-gut axis-modulating interventions in ME/CFS or Long COVID was conducted.

Results: The patient exhibited a significant reduction in total fatigue, with early improvements in motivation and mental fatigue, and delayed improvement in physical fatigue following transient systemic symptom flares. Across included RCTs (n = 8, 790 participants), four investigated gut microbiome-modulating therapies and four employed nerve stimulation. Synbiotic and herbal interventions demonstrated benefits for fatigue or PEM, accompanied by alterations in specific bacterial populations or CNS metabolisms. Regarding nerve stimulation, transcranial direct current stimulation (tDCS) combined with exercise program improved fatigue, whereas standalone tDCS, auricular or peripheral TENS showed limited efficacy.

Conclusion: Brain-gut axis-based interventions may alleviate fatigue in ME/CFS and Long COVID by potentially modulating neuroinflammation, restoring microbiome balance, and improving epithelial barrier function. EA-based vagal stimulation represents a feasible option for patients with severe or treatment-resistant symptoms. Larger mechanistic studies and rigorously designed RCTs are needed to establish therapeutic targets and optimize intervention strategies.

No consistent evidence for the anti-inflammatory effect of vagus nerve stimulation in humans: A systematic review and meta-analysis

Abstract

Vagus nerve stimulation (VNS) has been identified as an innovative immunosuppressive treatment strategy in rodent studies. However, its’ clinical potential is still unclear. Therefore, we aimed to assess whether VNS can reduce inflammatory proteins and/or immune cells in humans, through a pre-registered systematic review and meta-analysis according to PRISMA guidelines. The databases Cochrane, Pubmed and World of Knowledge were searched in duplicate up to the 3rd of March 2022 and publications from identified clinical trial registrations were identified until 20th of August 2023. Studies were included if they provided peer-reviewed data for humans who received VNS as short-term (<=1 day) or long-term (>=2 days-365 days) stimulation and reported at least one cytokine or immune cell after treatment.

Screening of title, abstract, full text, and data extraction was performed in duplicate by two independent reviewers. Data were pooled using a random-effects model and meta-regression was performed for moderating factors. Reporting bias was assessed. The standardized mean difference (Hedge’s g) was used to indicate overall differences of cytokine data (mean and standard deviation or median and interquartile range at the study level) to test our a-priori hypothesis.

The systematic review of 36 studies with 1135 participants (355 receiving a control/sham condition and 780 receiving VNS) revealed anti-inflammatory effects of VNS for cytokines in several reports, albeit often in subgroup analyses, but our meta-analyses of 26 studies did not confirm these findings. Although most cytokines were numerically reduced, the reduction did not reach statistical significance after VNS: not in the between-group comparisons (short-term: TNF-α: g = -0.21, p = 0.359; IL-6: g = -0.94, p = 0.112; long-term: TNF-α: g = -0.13, p = 0.196; IL-6: g = -0.67, p = 0.306); nor in the within-study designs (short-term: TNF-α: g = -0.45, p = 0.630; IL-6: g = 0.28, p = 0.840; TNF-α: g = -0.53, p = 0.297; IL-6:g = -0.02, p = 0.954). Only the subgroup analysis of 4 long-term studies with acute inflammation was significant: VNS decreased CRP significantly more than sham stimulation. Additional subgroup analyses including stimulation duration, stimulation method (invasive/non-invasive), immune stimulation, and study quality did not alter results. However, heterogeneity was high, and most studies had poor to fair quality. Given the low number of studies for each disease, a disease-specific analysis was not possible.

In conclusion, while numeric effects were reported in individual studies, the current evidence does not substantiate the claim that VNS impacts inflammatory cytokines in humans. However, it may be beneficial during acute inflammatory events. To assess its full potential, high-quality studies and technological advances are required.

From tradition to healing: the promise of acupuncture in managing chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS) is a global public health problem affecting more than 65 million patients worldwide. The combined prevalence rate of CFS was 45.2% after 4 weeks in patients with novel coronavirus. Women, people over 40 years of age, and low-income people are susceptible groups, which have a significant impact on immune, nervous, endocrine, and other system functions.

First, from the perspective of epidemiology, this paper reviews the global epidemic trend of CFS, the differences in incidence and prevalence in different regions and populations, and risk factors such as heredity, infection, and childhood trauma. Second, the development of diagnostic techniques for CFS, including the evolution of clinical diagnostic criteria, research progress on immune and metabolic biomarkers, and the application of MRI and other imaging techniques in the diagnosis of CFS, is described, followed by an in-depth discussion of the genetics of CFS, including genetic susceptibility, genomic association, and familial aggregation. The pathophysiological mechanism of CFS was also analyzed, revealing abnormalities in NK cell function and immune factors in the immune system, dysfunction of the hypothalamic-pituitary-adrenal axis in the neuroendocrine system, and disorders of energy and lipid metabolism in the metabolic system.

This paper focuses on the study of acupuncture and moxibustion treatment of CFS, traces back to the historical application of acupuncture and moxibustion treatment of CFS, analyzes the relationship between the pathological mechanism of CFS and acupuncture and moxibustion intervention, expounds the theoretical basis of traditional Chinese medicine and modern mechanism of action of acupuncture and moxibustion treatment, and introduces the results of clinical trials, efficacy evaluation methods, and individualized treatment strategies for acupuncture and moxibustion treatment of CFS.

The innovative application of acupuncture techniques, such as electroacupuncture and acupoint catgut embedding, as well as the synergistic effect of acupuncture combined with traditional Chinese medicine and psychotherapy, are shown. At the same time, disputes and challenges in the efficacy, safety, and ethics of acupuncture treatment for CFS were pointed out, and future research directions, potential breakthroughs, and international cooperation opportunities of acupuncture treatment for CFS are discussed. This study provides a comprehensive reference for clinical treatment and research on CFS.

Use and Perceived Helpfulness of Different Intervention Strategies in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome and Depression

Abstract:

Background: Patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) or depression both frequently report debilitating exhaustion, yet the two conditions differ in their etiological and diagnostic clarity, and clinical management. This study aimed to examine differences in the use and perceived helpfulness of a broad range of conventional treatments and complementary interventions, including nutritional approaches, between patients with ME/CFS and depression.

Methods: A cross-sectional online survey was conducted in 2024. A total of 819 participants self-identified as having either ME/CFS (n = 576) or depression (n = 243). Participants (80% female) reported their use and perceived helpfulness of 52 treatments and interventions, encompassing behavioral therapies, medications, and dietary supplements. Group differences were examined using multivariate analyses of variance and covariance (MANOVA/MANCOVA). Open-ended responses were analyzed descriptively using thematic grouping and frequency counts.

Results: Participants with depression most commonly reported the use of psychotherapy (M = 2.49, SD = 1.00) and antidepressant medication (M = 2.44, SD = 2.30), and they rated fewer interventions as helpful compared to participants with ME/CFS. In contrast, participants with ME/CFS reported a significantly broader engagement with diverse intervention modalities, particularly pacing (M = 2.73, SD = 0.80) and dietary supplements (M = 2.43, SD = 1.09), and perceived many of them as helpful. Group differences remained significant after controlling for age, gender, and whether treatment was medically recommended. Supplements targeting energy metabolism (e.g., CoQ10, NADH) were especially favored among ME/CFS participants.

Conclusions: Findings suggest that participants with ME/CFS tend to adopt an exploratory and expansive intervention approach, potentially reflecting the lack of standardized guidelines and limited effectiveness of available treatment options. Participants with depression, in contrast, appeared to follow more guideline-concordant, evidence-based treatment pathways. Taken together, the findings point to a need for further development and evaluation of empirically supported, patient-centered treatment and intervention strategies for ME/CFS and suggest differences in clinical care structures between ME/CFS and depression.

Effects of recumbent isometric yoga on the daily functioning level of patients with myalgic encephalomyelitis/chronic fatigue syndrome: a randomized, controlled trial

Abstract:

Background: Although seated isometric yoga has been shown to reduce the fatigue and pain of patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), some patients who are for the most part bedridden have difficulty practicing it. Many patients with this disease also suffer from fibromyalgia (FM). We developed a recumbent isometric yoga program for patients who were for the most part bedridden, including patients with comorbid FM. The aim of this study was to investigate the effect of this recumbent isometric yoga intervention with such patients.

Methods: This was a randomized, controlled trial of 48 adult patients (7 male, 41 female, age 20-70 years) with ME/CFS without satisfactory improvement after ≥ 3 months of conventional therapy. They were divided randomly into a yoga group (n = 24) and a control group (n = 24). The yoga group received conventional therapy with recumbent isometric yoga practice for ~ 12 weeks (25-min sessions with a yoga instructor at hospital visits and daily in-home sessions). The control group received conventional therapy alone. The effect of recumbent isometric yoga on the level of functioning was assessed by measuring Performance Status (PS). Fatigue was assessed with self-rated questionnaires, including the Chalder Fatigue Scale (FS) and Profile of Mood States (POMS). Adverse events and benefits were recorded for the yoga group.

Results: After the intervention period, the PS score of the yoga group was significantly lower than that of the control group (P < 0.001), suggesting an improvement in functioning level. The Chalder FS score decreased in both groups, but the decrease was greater in the yoga group than in the control group (P < 0.01). Subgroup analysis showed that the Chalder FS score was reduced significantly only in the yoga group in patients with severe disease (P < 0.001) and those with comorbid FM (P < 0.01), although the PS scores did not differ significantly. In the yoga group, a single practice session with a yoga instructor significantly reduced fatigue and increased vigor in patients with severe disease and patients with comorbid FM. Patients reported no serious adverse effects and many benefits of recumbent isometric yoga, including improvements in physical symptoms and brain fog, enhanced awareness of their limits to activities that cause post-exertional malaise, and promotion of behavioral changes to live better within their limits.

Conclusions: Recumbent isometric yoga is an effective adjunctive therapy for patients with ME/CFS, including those for the most part bedridden and those who have FM.

The potential therapeutic approaches targeting gut health in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS): a narrative review

Abstract:

Background: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex disorder characterized by persistent fatigue and cognitive impairments, with emerging evidence highlighting the role of gut health in its pathophysiology. The main objective of this review was to synthesize qualitative and quantitative data from research examining the gut microbiota composition, inflammatory markers, and therapeutic outcomes of interventions targeting the microbiome in the context of ME/CFS.

Methods: The data collection involved a detailed search of peer-reviewed English literature from January 1995 to January 2025, focusing on studies related to the microbiome and ME/CFS. This comprehensive search utilized databases such as PubMed, Scopus, and Web of Science, with keywords including “ME/CFS,” “Gut-Brain Axis,” “Gut Health,” “Intestinal Dysbiosis,” “Microbiome Dysbiosis,” “Pathophysiology,” and “Therapeutic Approaches.” Where possible, insights from clinical trials and observational studies were included to enrich the findings. A narrative synthesis method was also employed to effectively organize and present these findings.

Results: The study found notable changes in the gut microbiota diversity and composition in ME/CFS patients, contributing to systemic inflammation and worsening cognitive and physical impairments. As a result, various microbiome interventions like probiotics, prebiotics, specific diets, supplements, fecal microbiota transplantation, pharmacological interventions, improved sleep, and moderate exercise training are potential therapeutic strategies that merit further exploration.

Conclusions: Interventions focusing on the gut-brain axis may help reduce neuropsychiatric symptoms in ME/CFS by utilizing the benefits of the microbiome. Therefore, identifying beneficial microbiome elements and incorporating their assessments into clinical practice can enhance patient care through personalized treatments. Due to the complexity of ME/CFS, which involves genetic, environmental, and microbial factors, a multidisciplinary approach is also necessary. Since current research lacks comprehensive insights into how gut health might aid ME/CFS treatment, standardized diagnostics and longitudinal studies could foster innovative therapies, potentially improving quality of life and symptom management for those affected.

Recovery from Myalgic Encephalomyelitis/Chronic Fatigue syndrome developed after severe acute respiratory syndrome coronavirus 2 vaccination: A case report

Abstract:

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a neurological adverse effect after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations. However, clinicians do not recognize the condition well, and no case report has shown a full recovery.

Case presentation: We present a 65-year-old Japanese female who experienced severe fatigue, postexertional malaise, orthostatic intolerance, and various symptoms after her third SARS-CoV-2 vaccination. Following thorough examinations and excluding other potential diagnoses, she met the diagnostic criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The symptoms persisted for 30 months and improved ultimately with comprehensive treatment and a self-management strategy, including pacing management, pharmacological treatments, and psychiatric interventions to support those struggling with the despair over the devastating symptoms.

Conclusion: This case report describes ME/CFS following the SARS-CoV-2 vaccination and its full recovery. It illustrates the importance of considering the differential diagnosis of psychiatric disorders and addressing the condition through psychiatric interventions. Our findings provide new insights into treating ME/CFS and the vaccination-related adverse effects.
