Long-chain acylcarnitine deficiency in patients with chronic fatigue syndrome. Potential involvement of altered carnitine palmitoyltransferase-I activity

Abstract:

OBJECTIVE: The underlying aetiology of chronic fatigue syndrome is currently unknown; however, in the light of carnitine’s critical role in mitochondrial energy production, it has been suggested that chronic fatigue syndrome may be associated with altered carnitine homeostasis. This study was conducted to comparatively examine full endogenous carnitine profiles in patients with chronic fatigue syndrome and healthy controls.

DESIGN: A cross-sectional, observational study.

SETTING AND SUBJECTS: Forty-four patients with chronic fatigue syndrome and 49 age- and gender-matched healthy controls were recruited from the community and studied at the School of Pharmacy & Medical Sciences, University of South Australia.

MAIN OUTCOME MEASURES: All participants completed a fatigue severity scale questionnaire and had a single fasting blood sample collected which was analysed for l-carnitine and 35 individual acylcarnitine concentrations in plasma by LC-MS/MS.

RESULTS: Patients with chronic fatigue syndrome exhibited significantly altered concentrations of C8:1, C12DC, C14, C16:1, C18, C18:1, C18:2 and C18:1-OH acylcarnitines; of particular note, oleyl-L-carnitine (C18:1) and linoleyl-L-carnitine (C18:2) were, on average, 30-40% lower in patients than controls (P < 0.0001). Significant correlations between acylcarnitine concentrations and clinical symptomology were also demonstrated.

CONCLUSIONS: It is proposed that this disturbance in carnitine homeostasis is reflective of a reduction in carnitine palmitoyltransferase-I (CPT-I) activity, possibly a result of the accumulation of omega-6 fatty acids previously observed in this patient population. It is hypothesized that the administration of omega-3 fatty acids in combination with l-carnitine would increase CPT-I activity and improve chronic fatigue syndrome symptomology.

High cocoa polyphenol rich chocolate may reduce the burden of the symptoms in chronic fatigue syndrome

Abstract:

BACKGROUND: Chocolate is rich in flavonoids that have been shown to be of benefit in disparate conditions including cardiovascular disease and cancer. The effect of polyphenol rich chocolate in subjects with chronic fatigue syndrome (CFS) has not been studied previously.

METHODS: We conducted a double blinded, randomised, clinical pilot crossover study comparing high cocoa liquor/polyphenol rich chocolate (HCL/PR) in comparison to simulated iso-calorific chocolate (cocoa liquor free/low polyphenols(CLF/LP)) on fatigue and residual function in subjects with chronic fatigue syndrome. Subjects with CFS having severe fatigue of at least 10 out of 11 on the Chalder Fatigue Scale were enrolled. Subjects had either 8 weeks of intervention in the form of HCL/PR or CLF/LP, with a 2 week wash out period followed by 8 weeks of intervention with the other chocolate.

RESULTS: Ten subjects were enrolled in the study. The Chalder Fatigue Scale score improved significantly after 8 weeks of the HCL/PR chocolate arm [median (range) Exact Sig. (2-tailed)] [33 (25 – 38) vs. 21.5 (6 – 35) 0.01], but that deteriorated significantly when subjects were given simulated iso-calorific chocolate (CLF/CP) [ 28.5 (17 – 20) vs. 34.5 (13-26) 0.03]. The residual function, as assessed by the London Handicap scale, also improved significantly after the HCL/PR arm [0.49 (0.33 – 0.62) vs. 0.64 (0.44 – 0.83) 0.01] and deteriorated after iso-calorific chocolate [00.44 (0.43 – 0.68) vs. 0.36 (0.33 – 0.62)0.03]. Likewise the Hospital Anxiety and Depression score also improved after the HCL/PR arm, but deteriorated after CLF/CP. Mean weight remained unchanged throughout the trial.

CONCLUSION: This study suggests that HCL/PR chocolate may improve symptoms in subjects with chronic fatigue syndrome.

The search for pain relief in people with chronic fatigue syndrome: a descriptive study

Abstract:

The purpose of this study was to investigate the use and perceived benefit of complimentary and alternative medicine (CAM) and physiotherapy treatments tried by people with chronic fatigue syndrome (CFS) to ease painful symptoms. This study used a descriptive, cross-sectional design.

People with CFS who experienced pain were recruited to this study. Participants were asked during a semistructured interview about the treatments they had tried to relieve their pain. Each interview was conducted in the home of the participant. Fifty participants were recruited, of which, 10 participants were severely disabled by CFS. Eighteen participants were trying different forms of CAM treatment for pain relief at the time of assessment. Three participants were currently receiving physiotherapy.

Throughout the duration of their illness 45 participants reported trying 19 different CAM treatments in the search for pain relief. Acupuncture was reported to provide the most pain relief (n=16). Twenty-seven participants reported a total of 16 different interventions prescribed by their physiotherapist. The results of this study suggest some physiotherapy and CAM treatments may help people manage painful CFS symptoms. Future research should be directed to evaluating the effectiveness of interventions such as acupuncture or gentle soft tissue therapies to reduce pain in people with CFS.

Will vitamin D supplementation ameliorate diseases characterized by chronic inflammation and fatigue?

Abstract:

Chronic NF-κB activation has been supposed as a key event in chronic fatigue syndrome (CFS) and many other better-defined pro-inflammatory diseases. Knowledge about the impact of deficiency vitamin D on chronic NF-κB activation could open a new disease approach. Whereas NF-κB activation leads at first to a pro-inflammatory immune response, later on a vitamin D-dependent anti-inflammatory response ensues. Binding of the active vitamin D metabolite 1,25(OH)(2)D(3) to vitamin D receptor (VDR) yields a transcription factor which represses NF-κB activation, and additionally modulates and down-regulates adaptive, but enhances innate immune responses, and improves redox balance, thus counterbalancing inflammation on multiple levels. However, this built-in late counterbalance against inflammation works only when stores of calcium and 25(OH)D(3) are abundant. Therefore a connection between lowered vitamin D-metabolism and persistent NF-κB activation, augmented nitrosative-oxidative stress, redox imbalance, chronic inflammation, and concomitant fatigue can be postulated. In order to confirm this hypothesis, randomized controlled clinical studies about the clinical effects of supplementation of calcium and vitamin D(3) would be necessary in diseases characterized by persistent NF-κB activation and chronic inflammation and fatigue.

Randomized controlled study on acupuncture treatment for chronic fatigue syndrome

Abstract:

OBJECTIVE: To observe the therapeutic effect of acupuncture treatment for chronic fatigue syndrome (CFS).

METHODS: Ninety cases of CFS were randomly divided into an observation group and a control group, 45 cases in each group. The observation group was treated with acupuncture at Renying (ST 9), Fengfu (GV 16), Baihui (GV 20); the control group was treated with 250 mL 5% Glucose injection combined with 20 mL Shenmai injection. Fatigue Scale (FS) was used to compare the scores between the two groups after treatment.

RESULTS: The total scores in the observation group were 9.37 +/- 2.33 and 5.41 +/- 1.96 before and after treatment respectively, and in the control group, they were 9.08 +/- 2.27 and 7.34 +/- 2.03 respectively. FS brainwork integral, physical fatigue integral, and total integral all decreased after treatment in two groups (all P < 0.001), and it decreased much more obviously in the observation group (P < 0.05, P < 0.01).

CONCLUSION: Both of the acupuncture treatment and Shenmai injection are able to decrease fatigue scale score, improve the fatigue symptoms of CFS patients, and the effect of acupuncture treatment is obviously superior to that of Shenmai injection.

Effect of electroacupuncture at Shenshu (BL 23) and Zusanli (ST 36) on the event-related potentials of chronic fatigue syndrome

Abstract:

OBJECTIVE: To observe the effective mechanism of electroacupuncture for chronic fatigue syndrome (CFS).

METHODS: The dynamic detection of chronobiology was used to test the event-related potentials in 20 healthy subjects and 20 CFS patients. P3a and P3b latencies at 4 equidistant time points (8:00, 14:00, 20:00, 2:00) within 24 hours were collected and analyzed.

RESULTS: (1) Latency of P3a in CFS group was obviously prolonged at 14:00 compared to health group with statistical significance (P < 0.05), latency of P3b was decreased at 14:00 after electroacupuncture treatment with statistical significance compared to that of pre-treatment (P < 0.01). (2) There were obviously circadian rhythm in latency of P3a and P3b in health group (P < 0.05), which were not seen in CFS group (P > 0.05); the circadian rhythm latency of P3b restored after treatment (P < 0.05). (3) The latency acrophase of P3a and P3b pre-treatment obviously shifted backward compared to that of healthy subjects (P < 0.05), shifted forward after electroacupuncture treatment (P < 0.05).

CONCLUSION: The event-related potential circadian rhythms are lost in CFS patients. Electroacupuncture at Shenshu (BL 23) and Zusanli (ST 36) can regulate the circadian rhythm of P3a and P3b latency and improve the cognition of the patients in daytime.

Possible role of oxidative stress and immunological activation in mouse model of chronic fatigue syndrome and its attenuation by olive extract

Abstract:

Various putative theories involved in the development of chronic fatigue syndrome revolve around the role of stress, infection and oxidative stress. Scientific evidence highlighting the protective role of nutritional supplements in chronic fatigue syndrome is lacking.

Based on these assumptions, the present study was designed to evaluate the effect of olive extract in a mouse model of immunologically-induced fatigue, wherein purified lipopolysaccharide (LPS) and Brucella abortus (BA) antigen were used as immunogens. The assessment of chronic fatigue syndrome was based on immobility period during chronic water-immersion stress test for 10 min daily. The stress-induced hyperalgesia was measured by tail withdrawal latency.

Mice challenged with LPS or BA for 19 days showed significant increase in the immobility time, hyperalgesia and oxidative stress on the 19th day. Serum tumor necrosis factor-alpha (TNF-α) levels were also markedly increased with LPS or BA challenge.

Concurrent treatment with olive extract resulted in a significant decrease in the immobility time as well as hyperalgesia. There was significant attenuation of oxidative stress as well as serum TNF-α levels. The results of the present study strongly indicate the role of oxidative stress and immunological activation in the pathophysiology of chronic fatigue syndrome and highlight the valuable role of olive extract in combating chronic fatigue syndrome.

Nicotinamide adenine dinucleotide (NADH) in patients with chronic fatigue syndrome

Abstract:

BACKGROUND: Nicotinamide adenine dinucleotide (NADH) may be depleted in chronic fatigue syndrome (SFC). The purpose of the study was to evaluate the efficacy of supplementation with NADH in these patients.

MATERIAL AND METHODS: A double blind, placebo controlled, 3 month long clinical trial was conducted. The patients were randomized to oral NADH oral 20mg or placebo during the first two months. The intensity of the fatigue, functional performance, mood state, functional impact of the fatigue, quality of life, sleep quality, exercise capacity and functional reserve as well as the investigator’s and patient’s opinion on the efficacy of the intervention prior to and at 30, 60 and 90 days of the onset of the treatment were evaluated. A stress test was performed in the baseline visit and at 60 days (last day of the double blind treatment).

RESULTS: A total of 86 patients, 77 of whom completed the study (mean age, 47 years, 72 women) were enrolled. No significant differences were found in most of the variable studied at the end of the study. Administration of NADH was associated to a decrease in anxiety condition of -1.0 points (p<0.05) and of -0.2 points (p=NS) in the placebo assigned group. Maximum heart rate after the stress test decreased a mean of -8.1l/min (p<0.05) in the NADH group and increased by +1.7l/min in the placebo group (p=0.73). No differences were found in the perception of efficacy with NADH and placebo, by the investigator and patients.

CONCLUSIONS: Administration of oral NADH was associated to a decrease in anxiety and maximum heart rate, after a stress test in patients with CFS. On the contrary, this treatment did not modify other clinical variables and the global functional performance.

A meta analysis on randomized controlled trials of acupuncture treatment of chronic fatigue syndrome

Abstract:

OBJECTIVE: To assess the effectiveness of acupuncture treatment of chronic fatigue syndrome (CFS).

METHODS: According to the requirement of evidence-based medicine, CFS, fatigue syndrome, acupuncture and moxibustion, acupuncture, electroacupuncture, auricular acupuncture, auricular pellet pressure, plum-blossom needle, intradermal needle, moxibustion, three edged needle, cupping, cup-moving, acupoint injection, etc. were selected as the subject words for retrieving the related papers form domestic and foreign medical databases. The RCT was used as the enrolled criteria, and the clinical cure rate, markedly effective rate, total effective rate, and the scores of the Fatigue Assessment Instrument Questionnaire (FAI) and fatigue scale (FS) were used as the assessment indexes. The statistical package (RevMan 4.2) was used to review management and analysis of 13 papers.

RESULTS: A total of 28 papers were enrolled. Logistic regression analysis showed that the total odds ratio (OR) was 4.56, with 95% confidence interval (CI) [2.84, 7.33] for the total effective rate in 10 studies, the total OR was 2.07 with 95% CI [1.49, 2.88] for the markedly effective rate in 8 studies, and the total OR was 2.51 with 95% CI [1.64, 3.85] for the clinical cure rate in 8 studies. The weighted mean difference (WMD) was -29.52 with 95% CI [-36.17, -22.88] for the FAI score in 3 studies, and the WMD -1.22 with 95% CI [-1.77, -0.67] for the FS score in 4 studies. The therapeutic effect in the treatment group of CFS was superior to that in the control group (P<0.01).

CONCLUSION: Acupuncture therapy is effective for CFS, but still needs being confirmed by more high-quality studies.

Alternative medical interventions used in the treatment and management of myalgic encephalomyelitis/chronic fatigue syndrome and fibromyalgia

Abstract:

BACKGROUND: There have been several systematic reviews attempting to evaluate the efficacy of possible treatments for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and fibromyalgia (FM). However, information regarding the efficacy of complementary and alternative medicine (CAM) has not been comprehensively or systematically covered in these reviews, despite its frequent use in the patient community.

PURPOSE: The purpose of this study was to systematically review and evaluate the current literature related to alternative and complementary treatments for ME/CFS and FM. It should be stressed that the treatments evaluated in this review do not reflect the clinical approach used by most practitioners to treat these illnesses, which include a mix of natural and unconventionally used medications and natural hormones tailored to each individual case. However, nearly all clinical research has focused on the utility of single CAM interventions, and thus is the primary focus of this review.

METHODS: Several databases (e.g., PubMed, MEDLINE,((R)) PsychInfo) were systematically searched for randomized and nonrandomized controlled trials of alternative treatments and nonpharmacological supplements. Included studies were checked for references and several experts were contacted for referred articles. Two leading subspecialty journals were also searched by hand. Data were then extracted from included studies and quality assessments were conducted using the Jadad scale.

RESULTS: Upon completion of the literature search and the exclusion of studies not meeting criterion, a total of 70 controlled clinical trials were included in the review. Sixty (60) of the 70 studies found at least one positive effect of the intervention (86%), and 52 studies also found improvement in an illness-specific symptom (74%). The methodological quality of reporting was generally poor.

CONCLUSIONS: Several types of alternative medicine have some potential for future clinical research. However, due to methodological inconsistencies across studies and the small body of evidence, no firm conclusions can be made at this time. Regarding alternative treatments, acupuncture and several types of meditative practice show the most promise for future scientific investigation. Likewise, magnesium, l-carnitine, and S-adenosylmethionine are nonpharmacological supplements with the most potential for further research. Individualized treatment plans that involve several pharmacological agents and natural remedies appear promising as well.
