Effect of natural and synthetic antioxidants in a mouse model of chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS) is an illness characterized by persistent and relapsing fatigue, often accompanied by numerous symptoms involving various body systems. The etiology of CFS remains unclear; however, a number of studies have shown that oxidative stress may be involved in its pathogenesis. In the present study, a mouse model of CFS was used in which mice were forced to swim for one 6-minute session on each day for 15 days and the immobility period was recorded.

There was a significant increase in immobility period in saline-treated mice on successive days. Intraperitoneal treatment with the potent antioxidants carvedilol (5 mg/kg) and melatonin (5 mg/kg) produced a significant reduction in immobility period. Similar results were observed with herbal preparations administered orally: Withania somnifera (100 mg/kg), quercetin (50 mg/kg), and St. John’s wort (Hypericum perforatum L., 10 mg/kg). Biochemical analysis revealed that chronic swimming significantly induced lipid peroxidation and decreased glutathione (GSH) levels in the brains of mice. The rats also showed decreased levels of antioxidant defense enzymes, superoxide dismutase (SOD), and catalase. Co-administration of antioxidants carvedilol, melatonin, W. somnifera, quercetin or St. John’s wort significantly reduced lipid peroxidation and restored the GSH levels decreased by chronic swimming in mice. Further, the treatment increased levels of SOD in the forebrain and of catalase.

The findings strongly suggest that oxidative stress plays a significant role in the pathophysiology of CFS and that antioxidants could be useful in the treatment of CFS.

Relationship between musculoskeletal symptoms and blood markers of oxidative stress in patients with chronic fatigue syndrome

Abstract:

In 21 patients with chronic fatigue syndrome (CFS) versus 20 normal subjects, we investigated the oxidant/antioxidant balance and its correlation with muscle symptoms. Patients versus controls showed significantly: lower Lag Phase and Vitamin E (Vit E) concentrations in plasma and low-density lipoproteins (LDL), higher LDL thiobarbituric acid reactive substances (TBARS), higher fatigue and lower muscle pain thresholds to electrical stimulation.

A significant direct linear correlation was found between fatigue and TBARS, thresholds and Lag Phase, thresholds and Vit E in plasma and LDL. A significant inverse linear correlation was found between fatigue and Lag Phase, fatigue and Vit E, thresholds and TBARS. Increased oxidative stress and decreased antioxidant defenses are related to the extent of symptomatology in CFS, suggesting that antioxidant supplementation might relieve muscle symptoms in the syndrome.

Therapy of circadian rhythm disorders in chronic fatigue syndrome: no symptomatic improvement with melatonin or phototherapy

Abstract:

BACKGROUND: Patients with chronic fatigue syndrome (CFS) show evidence of circadian rhythm disturbances. We aimed to determine whether CFS symptoms were alleviated by melatonin and bright-light phototherapy, which have been shown to improve circadian rhythm disorders and fatigue in jet-lag and shift workers.

DESIGN: Thirty patients with unexplained fatigue for > 6 months were initially assessed using placebo and then received melatonin (5 mg in the evening) and phototherapy (2500 Lux for 1 h in the morning), each for 12 weeks in random order separated by a washout period. Principal symptoms of CFS were measured by visual analogue scales, the Shortform (SF-36) Health Survey, Mental Fatigue Inventory and Hospital Anxiety and Depression Scale. We also determined the circadian rhythm of body temperature, timing of the onset of melatonin secretion, and the relationship between these.

RESULTS: Neither intervention showed any significant effect on any of the principal symptoms or on general measures of physical or mental health. Compared with placebo, neither body temperature rhythm nor onset of melatonin secretion was significantly altered by either treatment, except for a slight advance of temperature phase (0.8 h; P = 0.04) with phototherapy.

CONCLUSION: Melatonin and bright-light phototherapy appear ineffective in CFS. Both treatments are being prescribed for CFS sufferers by medical and alternative practitioners. Their unregulated use should be prohibited unless, or until, clear benefits are convincingly demonstrated.

The treatment of small intestinal bacterial overgrowth with enteric-coated peppermint oil: a case report

Abstract:

Recent investigations have shown that bacterial overgrowth of the small intestine is associated with a number of functional somatic disorders, including irritable bowel syndrome (IBS), fibromyalgia, and chronic fatigue syndrome.

A number of controlled studies have shown that enteric-coated peppermint oil (ECPO) is of benefit in the treatment of IBS. However, despite evidence of strong antimicrobial activity, ECPO has not been specifically investigated for an effect on small intestinal bacterial overgrowth (SIBO).

A case report of a patient with SIBO who showed marked subjective improvement in IBS-like symptoms and significant reductions in hydrogen production after treatment with ECPO is presented. While further investigation is necessary, the results in this case suggest one of the mechanisms by which ECPO improves IBS symptoms is antimicrobial activity in the small intestine.

Intravenous nutrient therapy: the “Myers’ cocktail”

Abstract:

Building on the work of the late John Myers, MD, the author has used an intravenous vitamin-and-mineral formula for the treatment of a wide range of clinical conditions. The modified “Myers’ cocktail,” which consists of magnesium, calcium, B vitamins, and vitamin C, has been found to be effective against acute asthma attacks, migraines, fatigue (including chronic fatigue syndrome), fibromyalgia, acute muscle spasm, upper respiratory tract infections, chronic sinusitis, seasonal allergic rhinitis, cardiovascular disease, and other disorders. This paper presents a rationale for the therapeutic use of intravenous nutrients, reviews the relevant published clinical research, describes the author’s clinical experiences, and discusses potential side effects and precautions.

Homeopathic treatment of Chronic Fatigue Syndrome: three case studies using Jan Scholten’s methodology

Abstract:

This paper explores the treatment of Chronic Fatigue Syndrome following a viral infection in young people. The methodology is based on that of Dr Jan Scholten, Holland, who has systematically described the homeopathic themes of all elements in the periodic table. Three case studies are presented, Cobaltum Phosphoricum, Calcium Phosphoricum and Cadmium Phosphoricum were prescribed. The common themes and the differentiating features of these Phosphate salts are described in detail to show how the homeopathic similimum is found and cure achieved.

The effect of a polynutrient supplement on fatigue and physical activity of patients with chronic fatigue syndrome: a double-blind randomized controlled trial

Abstract:

BACKGROUND: The efficacy of dietary supplements in chronic fatigue syndrome (CFS) is uncertain, with conflicting evidence.

AIM: To assess the effect of a polynutrient supplement on fatigue and physical activity of patients with CFS.

DESIGN: Prospective randomized placebo-controlled, double-blind trial.

METHODS: Fifty-three patients (16 males, 37 females) fulfilling the CDC criteria of CFS. The entry criteria were a score on the Checklist Individual Strength subscale fatigue severity (CIS fatigue) >or=40 and a weighted sum score of >or=750 for the eight subscales of the Sickness Impact Profile (SIP8) and no use of nutritional supplements in the 4 weeks prior to entry. The exclusion criteria were pregnancy and lactose intolerance. The intervention-a polynutrient supplement containing several vitamins, minerals and (co)enzymes, or placebo, twice daily for 10 weeks-was preceded by 2 weeks of baseline measurements. Outcome measurements took place in week 9 and 10 of the intervention. Five participants dropped out (4 supplement, 1 placebo). The main outcome measures were CIS fatigue score, number of CDC symptoms and SIP8 score. Efficacy analyses were performed on an intention-to-treat basis.

RESULTS: No significant differences were found between the placebo and the treated group on any of the outcome measures: CIS fatigue +2.16 (95%CI -4.3 to +4.39, p=0.984); CDC symptoms +0.42 (95%CI -0.61 to +1.46, p=0.417); SIP8 +182 (95%CI -165 to +529, p=0.297). No patient reported full recovery.

DISCUSSION: The findings do not support the use of a broad-spectrum nutritional supplement in treating CFS-related symptoms.

Treatment of chronic fatigue syndrome by dietary supplementation with omega-3 fatty acids–a good idea?

Abstract:

Minor alterations of immune, neuroendocrine, and autonomic function may be associated with the chronic fatigue syndrome. omega-3 fatty acids decrease the production of putative mediators of inflammation, including interleukin-1, and tumor necrosis factor. Since interleukin-1 and tumor necrosis factor are the principal polypeptide mediators of immunoregulation, reduced production of these cytokines by dietary supplementation with omega-3, may be a possible mechanism for the treatment of chronic fatigue syndrome.

Treatment of chronic fatigue with neurofeedback and self-hypnosis

Abstract:

A 21 year old patient reported a relatively rapid onset of serious chronic fatigue syndrome (CFS), with her worst symptoms being cognitive impairments. Congruent with research on rapid onset CFS, she had no psychiatric history and specialized testing did not suggest that somatization was likely. Neuroimaging and EEG research has documented brain dysfunction in cases of CFS. Therefore, a quantitative EEG was done, comparing her to a normative data base. This revealed excessive left frontal theta brainwave activity in an area previously implicated in SPECT research.

Therefore, a novel treatment approach was utilized consisting of a combination of EEG neurofeedback and self-hypnosis training, both of which seemed very beneficial. She experienced considerable improvement in fatigue, vigor, and confusion as measured pre-post with the Profile of Mood States and through collaborative interviews with both parents. Most of the changes were maintained at 5, 7, and 9 month follow-up testing.

Cognitive behavioral therapy and fasting therapy for a patient with chronic fatigue syndrome

Abstract:

Cognitive behavioral therapy temporarily alleviated symptoms of a chronic fatigue syndrome patient but the anxiety about rehabilitation into work became stronger and his symptoms worsened. This patient was successfully rehabilitated by fasting therapy. Natural killer cell activity and serum acylcarnitine levels recovered after fasting therapy. Though fasting therapy transiently increased physical and mental subjective symptoms, the patient gained self-confidence by overcoming difficulties after fasting therapy. A combination of cognitive behavioral therapy and fasting therapy is promising as a treatment for chronic fatigue syndrome.
