The effective mechanism of the polysaccharides from Panax ginseng on chronic fatigue syndrome

Abstract:

Ginseng acidic polysaccharide WGPA isolated from the root of Panax ginseng C. A. Meyer was fractionated into WGPA-A and WGPA-N by anion-exchange chromatography. The antifatigue activity of ginseng acidic polysaccharide WGPA has been reported in our previous research. This present study was designed to identify its active component and elucidate the mechanism for preventing chronic fatigue syndrome (CFS).

WGPA, WGPA-A and WGPA-N were orally administered to mice once daily for 15 days. The effects of these compounds on physiological biomarkers of oxidative stress and on the morphology of the mitochondria in striated skeletal muscle were assessed. The results of forced swimming test-induced indicated that WGPA and WGPA-A could lengthen the swimming time, while WGPA-N could not. In addition, malondialdehyde and lactate dehydrogenase levels in serum were enhanced; while those of superoxide dismutase and glutathione peroxidase were lowered. Interestingly, the structural degeneration of mitochondria were all ameliorated.

These findings suggested that WGPA-A is the active component of WGPA, it might have potential therapeutic effects for CFS and the oxidative stress might be involved in the pathogenesis. Our results also provided essential data for a better understanding of the antifatigue effects of P. ginseng extracts.

Bifidobacterium infantis 35624 modulates host inflammatory processes beyond the gut

Abstract:

Certain therapeutic microbes, including Bifidobacteria infantis (B. infantis) 35624 exert beneficial immunoregulatory effects by mimicking commensal-immune interactions; however, the value of these effects in patients with non-gastrointestinal inflammatory conditions remains unclear.

In this study, we assessed the impact of oral administration of B. infantis 35624, for 6‒8 weeks on inflammatory biomarker and plasma cytokine levels in patients with ulcerative colitis (UC) (n = 22), chronic fatigue syndrome (CFS) (n = 48) and psoriasis (n = 26) in three separate randomized, double-blind, placebo-controlled interventions. Additionally, the effect of B. infantis 35624 on immunological biomarkers in healthy subjects (n = 22) was assessed.

At baseline, both gastrointestinal (UC) and non-gastrointestinal (CFS and psoriasis) patients had significantly increased plasma levels of C-reactive protein (CRP) and the pro-inflammatory cytokines tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) compared with healthy volunteers. B. infantis 35624 feeding resulted in reduced plasma CRP levels in all three inflammatory disorders compared with placebo.

Interestingly, plasma TNF-α was reduced in CFS and psoriasis while IL-6 was reduced in UC and CFS. Furthermore, in healthy subjects, LPS-stimulated TNF-α and IL-6 secretion by peripheral blood mononuclear cells (PBMCs) was significantly reduced in the B. infantis 35624-treated groups compared with placebo following eight weeks of feeding.

These results demonstrate the ability of this microbe to reduce systemic pro-inflammatory biomarkers in both gastrointestinal and non-gastrointestinal conditions. In conclusion, these data show that the immunomodulatory effects of the microbiota in humans are not limited to the mucosal immune system but extend to the systemic immune system.

An open-label study of effects of acupuncture on chronic fatigue syndrome and idiopathic chronic fatigue: study protocol for a randomized controlled trial

Abstract:

BACKGROUND: Even though chronic fatigue syndrome and idiopathic chronic fatigue are quite common, there are no clearly known causes. Most treatments are therefore symptomatic in nature, and chronic fatigue syndrome and idiopathic chronic fatigue patients are highly interested in using oriental medicine or complementary and alternative medicine treatment. Acupuncture, one of the major treatments used in oriental medicine, is effective in treating various diseases. This study will attempt to analyze the effectiveness and safety of acupuncture in the treatment of chronic fatigue by comparing the two treatment groups (body acupuncture, Sa-am acupuncture) and the control group (usual care).

METHODS/DESIGN: This study consists of a four-center, three-arm, randomized, controlled, and open-label trial. One hundred and fifty participants are randomly divided into treatment groups A and B and a control group. The treatment groups will receive acupuncture treatments either two or three times per week for a total of 10 sessions over a period of 4 weeks. The control group will not receive acupuncture treatments and will continue their usual care during this period. The primary outcome variable is the Fatigue Severity Scale, which will be utilized 5 weeks after randomization. Secondary outcome variables are the Fatigue Severity Scale at 13 weeks, a short form of the Stress Response Inventory, the Beck Depression Inventory, the Numeric Rating Scale, and the EuroQol-5 Dimension at 5 and 13 weeks after randomization.

DISCUSSION: This study will provide evidence with high external validity on the effectiveness and safety of acupuncture as a treatment for chronic fatigue syndrome and idiopathic chronic fatigue.

The efficacy of hyperbaric oxygen therapy in the management of chronic fatigue syndrome

Erratum in: Undersea Hyperb Med. 2013 May-Jun;40(3):312.

Abstract:

OBJECTIVE: Chronic fatigue syndrome (CFS) is a chronic disease with social components that ensue secondary to the incapacity of the person to fulfill work, social and family responsibilities. Currently, there is no consensus regarding its treatment. The aim of this study was to determine the efficacy of hyperbaric oxygen (HBO2) therapy in CFS.

DESIGN: Sixteen patients included in the study were diagnosed with CFS according to the Fukuda criteria. Patients received 15 treatment sessions of HBO2 therapy over a period of three consecutive weeks (five days per week). The outcome measures (visual analog fatigue scale (VAFS). Fatigue Severity Scale (FSS) and Fatigue Quality of Life Score (FQLS) were assessed before the treatment and after completion of the 15 sessions.

RESULTS: HBO2 therapy was well tolerated, with no complications. After treatment, patients’ scores were found to have improved with respect to VAFS, FSS and FQLS (all p<0.005).

CONCLUSIONS: We may infer that HBO2 therapy decreases the severity of symptoms and increases the life quality of CFS patients. It may be a new treatment modality for the management of CFS. However, further studies with larger sample sizes and control groups are definitely awaited.

Immunostimulation in the treatment for chronic fatigue syndrome/myalgic encephalomyelitis

Abstract:

Chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) has long been associated with the presence of infectious agents, but no single pathogen has been reliably identified in all patients with the disease. Recent studies using metagenomic techniques have demonstrated the presence of thousands of microbes in the human body that were previously undetected and unknown to science. More importantly, such species interact together by sharing genes and genetic function within communities. It follows that searching for a singular pathogen may greatly underestimate the microbial complexity potentially driving a complex disease like CFS/ME. Intracellular microbes alter the expression of human genes in order to facilitate their survival.

We have put forth a model describing how multiple species-bacterial, viral, and fungal-can cumulatively dysregulate expression by the VDR nuclear receptor in order to survive and thus drive a disease process. Based on this model, we have developed an immunostimulatory therapy that is showing promise inducing both subjective and objective improvement in patients suffering from CFS/ME.

Shilajit attenuates behavioral symptoms of chronic fatigue syndrome by modulating the hypothalamic-pituitary-adrenal axis and mitochondrial bioenergetics in rats

Abstract:

ETHNOPHARMACOLOGICAL RELEVANCE: Shilajit has been used as a rejuvenator for ages in Indian ancient traditional medicine and has been validated for a number of pharmacological activities.

AIM OF THE STUDY: The effect of processed shilajit which was standardized to dibenzo-α-pyrones (DBPs;0.43% w/w), DBP-chromoproteins (DCPs; 20.45% w/w) and fulvic acids (56.75% w/w) was evaluated in a rat model of chronic fatigue syndrome (CFS). The mitochondrial bioenergetics and the activity of hypothalamus-pituitary-adrenal (HPA) axis were evaluated for the plausible mechanism of action of shilajit.

MATERIALS AND METHODS: CFS was induced by forcing the rats to swim for 15mins for 21 consecutive days. The rats were treated with shilajit (25, 50 and 100mg/kg) for 21 days before exposure to stress procedure. The behavioral consequence of CFS was measured in terms of immobility and the climbing period. The post-CFS anxiety level was assessed by elevated plus maze (EPM) test. Plasma corticosterone and adrenal gland weight were estimated as indices of HPA axis activity. Analysis of mitochondrial complex chain enzymes (Complex I, II, IV and V) and mitochondrial membrane potential (MMP) in prefrontal cortex (PFC) were performed to evaluate the mitochondrial bioenergetics and integrity respectively.

RESULTS: Shilajit reversed the CFS-induced increase in immobility period and decrease in climbing behavior as well as attenuated anxiety in the EPM test. Shilajit reversed CFS-induced decrease in plasma corticosterone level and loss of adrenal gland weight indicating modulation of HPA axis. Shilajit prevented CFS-induced mitochondrial dysfunction by stabilizing the complex enzyme activities and the loss of MMP. Shilajit reversed CFS-induced mitochondrial oxidative stress in terms of NO concentration and, LPO, SOD and catalase activities.

CONCLUSION: The results indicate that shilajit mitigates the effects of CFS in this model possibly through the modulation of HPA axis and preservation of mitochondrial function and integrity. The reversal of CFS-induced behavioral symptoms and mitochondrial bioenergetics by shilajit indicates mitochondria as a potential target for treatment of CFS.

A randomized controlled trial of qigong exercise on fatigue symptoms, functioning, and telomerase activity in persons with chronic fatigue or chronic fatigue syndrome

Abstract:

BACKGROUND: Chronic fatigue is common in the general population. Complementary therapies are often used by patients with chronic fatigue or chronic fatigue syndrome to manage their symptoms.

PURPOSE: This study aimed to assess the effect of a 4-month qigong intervention program among patients with chronic fatigue or chronic fatigue syndrome.

METHODS: Sixty-four participants were randomly assigned to either an intervention group or a wait list control group. Outcome measures included fatigue symptoms, physical functioning, mental functioning, and telomerase activity.

RESULTS: Fatigue symptoms and mental functioning were significantly improved in the qigong group compared to controls. Telomerase activity increased in the qigong group from 0.102 to 0.178 arbitrary units (p < 0.05). The change was statistically significant when compared to the control group (p < 0.05).

CONCLUSION: Qigong exercise may be used as an alternative and complementary therapy or rehabilitative program for chronic fatigue and chronic fatigue syndrome.

Patterns of food avoidance in chronic fatigue syndrome: is there a case for dietary recommendations?

Abstract:

OBJECTIVES: To assess the dietary habits and food avoidance-behavior in patients with Chronic Fatigue Syndrome (CFS).

METHODS: Cross-sectional pilot study with 28 patients diagnosed with severe CFS. Eating habits were assessed with a food frequency questionnaire and 3-day food records. We analyzed variables related to dietary restrictions induced by symptoms or external information.

RESULTS: The most prevalent restrictions were for dairy products and gluten-containing grains, with 22 and 15 restricting patients, respectively. Patients reported different digestive symptoms, which did not improve with the use of exclusion diets. Thirteen patients had received information against the intake of certain foods through different sources. Six cases of grains restriction and 11 of dairy were compatible with a counseling-induced pattern of exclusion.

CONCLUSIONS: There is not a homogeneous pattern of food avoidance. Dietary restrictions should be based on a proven food allergy or intolerance. Dietary counseling should be based on sound nutritional knowledge.

Effects of tuina on the mechanical properties of skeletal muscles of four limbs in patients with chronic fatigue syndrome

Abstract:

OBJECTIVE: To study the effects of tuina on the mechanical properties of skeletal muscles of four limbs in patients with chronic fatigue syndrome (CFS).

METHODS: Thirty CFS patients were recruited as the test group, while another 30 healthy volunteers were recruited as the healthy control group. Patients in the test group received tuina therapy, 30 min each time, once every other day, for totally 10 times. Isokinetic testing technology was used to compare peak torque (PT), total watt (TW), average power (AP), and flexor/extensor (F/E) ratio in the elbow and knee muscles of CFS patients before and after treatment. The Functional Assessment of Chronic Illness Therapy (FACIT) fatigue scale was used to evaluate the fatigue degree before and after treatment, and compared with the healthy control group.

RESULTS: After treatment the FACIT fatigue scale score decreased significantly in the test group when compared with before treatment (27.5 +/- 9.1 vs 42.5 +/- 11.2), showing statistical difference (P < 0.05). The pre-treatment PT, TW, AP, and F/E ratio in the skeletal muscle were all lower in the test group than in the healthy control group. Compared with before treatment in the test group, patients’ elbow 60 degrees/s angular velocity values during exercise extensor PT and TW, knee 60 degrees/s and 180 degrees/s angular velocity values during exercise flexor PT and TW increased significantly; elbow extensor and knee extensor, flexor AP was significantly elevated; knee in 180 degrees/s angular velocity of movement F/E ratio significantly increased, and all the differences were statistically significant (P < 0.05). The improvement of the fatigue degree in CFS patients and elbow in 60 degrees/s angular velocity values under the flexor and extensor TW, and flexor AP value of the degree of improvement were negatively correlated (r = -0.282, -0.482, -0.285, P < 0.05, P < 0.01). Meanwhile, the muscles with the knee in 180 degrees/s angular velocity was negatively correlated with the F/E ratio of the degree of improvement (r = -0. 330, P < 0.05).

CONCLUSIONS: CFS patients have lowered mechanical properties of four limbs. Tuina therapy can improve the biomechanical properties of limb skeletal muscle and reduce the overall degree of fatigue in patients. The changes of limb skeletal muscle and mechanical properties can provide objective reference for the clinical diagnosis and assessment of CFS.

Effect of acupuncture on serum malonaldehyde content, superoxide dismutase and glutathione peroxidase activity in chronic fatigue syndrome rats

Abstract:

OBJECTIVE: To study the effect of acupuncture on blood oxygen free radical metabolism in rats with chronic fatigue syndrome (CFS).

METHODS: Thirty male SD rats were randomly divided into control group (n = 10), model group (n = 10) and acupuncture group (n = 10). CFS model was established by repeated suspension (1.0-2.5 h) and forced cold water swimming (7 min), once daily continuously for 12 days. For rats in the acupuncture group, bilateral “Zusanli” (ST 36) and “Sanyinjiao” (SP 6) were stimulated by manipulating the acupuncture needles intermittently for 20 min, once daily, and with 7 days being a treatment course. The treatment was conducted for three courses with an interval of 3 days between two courses. Serum malonaldehyde (MDA) content, superoxide dismutase (SOD) activity, and glutathione peroxidase (GSH-PX) activity were detected by thiobarbituric acid chromatometry (TBA), xanthine oxidase (XOD) and dithio-bis-nitrobenzoic acid (DTNB), respectively.

RESULTS: In comparison with the control group, serum MDA content was up-regulated significantly, while serum SOD activity and GSH-PX activity were decreased considerably in the model group (P < 0.01). Compared with the model group, serum MDA level was down-regulated apparently, and serum SOD activity and GSH-PX activity were up-regulated remarkably in the acupuncture group (P < 0.01).

CONCLUSION: Acupuncture can adjust metabolism of serum oxygen free radicals in CFS rats, which probably contributes to its effect in relieving CFS in clinic.
