Increased HDAC in association with decreased plasma cortisol in older adults with chronic fatigue syndrome

Abstract:

Hypocortisolism is a frequent finding in individuals with chronic fatigue syndrome (CFS) with other research findings implying potential dysregulation of glucocorticoid signaling. Glucocorticoid signaling is under the influence of several pathways, several of which are of interest in the study of CFS. Oxidative stress and decreased antioxidant capacity are known to disrupt the hypothalamic-pituitary-adrenal (HPA) axis (Epel et al., 2004) and the presence of histone deacetylases (HDAC) could also impact glucocorticoid signaling.

The intent of this pilot study was to investigate the relationship among oxidative stress elements, select HDAC’s (2/3) and glucocorticoid receptor signaling in an elderly sample with CFS. Findings suggest increased histone deacetylase activity, lower total antioxidant power, in the context of decreased plasma cortisol and increased plasma dehydroepiandrosterone concomitant with decreased expression of the encoding gene for the glucocorticoid receptor. These findings support the presence of HPA axis dysregulation in elderly individuals with CFS.

Prospective observational study of treatments for unexplained chronic fatigue

Abstract:

BACKGROUND: Unexplained chronic fatigue is a frequent complaint in primary care. A prospective observational study design was used to evaluate whether certain commonly used therapies for unexplained chronic fatigue may be effective.

METHOD: Subjects with unexplained chronic fatigue of unknown etiology for at least 6 months were recruited from the Wisconsin Chronic Fatigue Syndrome Association, primary care clinics, and community chronic fatigue syndrome presentations. The primary outcome measure was change in a 5-question fatigue score from 6 months to 2 years. Self-reported interventions tested included prescribed medications, non-prescribed supplements and herbs, lifestyle changes, alternative therapies, and psychological support. Linear regression analysis was used to test the association of each therapy with the outcome measure after adjusting for statistically significant prognostic factors.

RESULTS: 155 subjects provided information on fatigue and treatments at baseline and follow-up. Of these subjects, 87% were female and 79% were middle-aged. The median duration of fatigue was 6.7 years. The percentage of users who found a treatment helpful was greatest for coenzyme Q10 (69% of 13 subjects), dehydroepiandrosterone (DHEA) (65% of 17 subjects), and ginseng (56% of 18 subjects). Treatments at 6 months that predicted subsequent fatigue improvement were vitamins (p = .08), vigorous exercise (p = .09), and yoga (p = .002). Magnesium (p = .002) and support groups (p = .06) were strongly associated with fatigue worsening from 6 months to 2 years. Yoga appeared to be most effective for subjects who did not have unclear thinking associated with the fatigue.

CONCLUSION: Certain alternative therapies for unexplained chronic fatigue, especially yoga, deserve testing in randomized controlled trials.

The clinical course of interstitial pneumonia alias chronic fatigue syndrome under the control of megadose vitamin C infusion system with dehydroepiandrosterone-cortisol annex

Abstract:

The year 1995 marked the onset of interstitial pneumonia spread in Nagoya, Japan. For the last 9 years, we have been accumulating clinical experience with the disease control using the combination of prophylactic use of anti-biotics and regular practice of megadose vitamin C infusion with either dehydroepiandrosterone-annex or dehydroepiandrosterone-cortisol annex. The purpose of this study is to assess the usefulness of our new treatment system for the control of interstitial pneumonia alias chronic fatigue syndrome.

The results obtained are given as follows:

i) The long-term maintenance of the above treatment system was effective not only for decreasing the risk for recurrence of active form pneumonia, but also for prevention of malignancy emergence in aged patients with interstitial pneumonia.

ii) Evidence is presented to indicate that interstitial pneumonia was associated with increased risk for depression of which the emergence is a candidate subject causally related to the long-term use of glucocorticoid.

iii) A patient with both interstitial pneumonia and depression was found to be less responsive to our treatment system. It is suggested that the use of more dehydroepiandrosterone at the sacrifice of cortisol in the infusion annex may be a choice for the control of both interstitial pneumonia and depression.

iv) The description of chronic fatigue syndrome as regards the endocrinological, epidemiological and psychiatric characteristics are in good agreement with our experience on patients having interstitial pneumonia, evidence in support of our proposal that there is no convincing reasoning to separate chronic fatigue syndrome from interstitial pneumonia.

v) The long-term practice of our treatment system for the control of interstitial pneumonia (an autoimmune disease) was found to suppress the inflammatory process but not the fibrotic process in the long run. vi) A few innovations were made in our treatment system to reduce the risk of bleeding or thrombosis–vascular complications of pneumonia.

vii) The merit of our treatment system is to create a new hormonal environment to improve the state of immunodeficiency by use of a non-steroid substance–vitamin C which encounters little resistance from the feedback mechanism of steroid metabolism in the in vivo system.

Levels of DHEA and DHEAS and responses to CRH stimulation and hydrocortisone treatment in chronic fatigue syndrome

Abstract:

BACKGROUND: An association between chronic fatigue syndrome (CFS) and abnormalities of the hypothalamo-pituitary-adrenal axis has been described, and other adrenal steroid abnormalities have been suggested. Dehydroepiandrostenedione (DHEA) and its sulphate (DHEA-S), apart from being a precursor of sex steroids, have other functions associated with memory, depression and sleep. It has been suggested that CFS may be associated with a state of relative DHEA(-S) deficiency. Therefore we investigated basal levels of DHEA(-S), the cortisol/DHEA molar ratio and the responsiveness of DHEA to stimulation by corticotrophin-releasing hormone (CRH). Recent studies have also suggested that low dose hydrocortisone may be effective at reducing fatigue in CFS. We therefore also assessed these parameters prior to and following treatment with low dose oral hydrocortisone.

METHODS: Basal levels of serum DHEA, DHEAS and cortisol were measured in 16 patients with CFS without depression and in 16 controls matched for age, gender, weight, body mass index and menstrual history. CRH tests (1 g/kg i.v.) were carried out on all subjects and DHEA measured at 0, +30 and +90 min. In the patient group, CRH tests were repeated on two further occasions following treatment with hydrocortisone (5 or 10 mg, p.o.) or placebo for 1 month each in a double-blind cross over study protocol.

RESULTS: Basal levels of DHEA were higher in the patient, compared to the control, group (14.1+/-2.2 vs. 9.0+/-0.90 ng/ml, P=0.04), while levels of DHEAS in patients (288.7+/-35.4 microg/dl) were not different from controls (293.7+/-53.8, P=NS). Higher DHEA levels were correlated with higher disability scores. Basal cortisol levels were higher in patients, and consequently the cortisol/DHEA molar ratio did not differ between patients and controls. Levels of DHEA (8.9+/-0.97 ng/ml, P=0.015) and DHEAS (233.4+/-41.6 microg/dl, P=0.03) were lower in patients following treatment with hydrocortisone. There was a rise in DHEA responsiveness to CRH in the patients after treatment but this did not attain significance (AUCc: 2.5+/-1.7 ng/ml h pre-treatment vs. 6.4+/-1.2 ng/ml h post-hydrocortisone, P=0.053). However, those patients who responded fully to hydrocortisone in terms of reduced fatigue scores did show a significantly increased DHEA responsiveness to CRH (AUCc: -1.4+/-2.5 ng/ml h at baseline, 5.0+/-1.2 ng/ml h after active treatment, P=0.029).

CONCLUSIONS: DHEA levels are raised in CFS and correlate with the degree of self-reported disability. Hydrocortisone therapy leads to a reduction in these levels towards normal, and an increased DHEA response to CRH, most marked in those who show a clinical response to this therapy.

Serum concentrations of some metals and steroids in patients with chronic fatigue syndrome with reference to neurological and cognitive abnormalities

Abstract:

Chronic fatigue syndrome is defined by the Atlanta Centers for Disease Control (Atlanta, GA, USA) as debilitating fatigue lasting for longer than 6 months. Symptoms include disturbances of cognition. Certain factors have in the past been shown to influence cognition, including metals such as aluminum, iron, and zinc; and steroids such as dehydroepiandrosterone.

In the present study, concentrations of these factors were determined in the serum and plasma of patients and their age- and gender-matched healthy controls (10 women and 5 men in each group). In addition, copper, dehydroepiandrosterone sulphate, cortisol, cholesterol, hemoglobin, ferritin and transferrin concentrations, as well as transferrin genetic subtypes were determined in both groups.

The results indicate that patients had significantly increased serum aluminum and decreased iron compared to controls. In the females, serum iron and dehydroepiandrosterone sulphate were significantly decreased and correlated. Total cholesterol was significantly increased, and significantly negatively correlated with dehydroepiandrosterone sulphate. There were no differences in zinc, copper, cortisol, hemoglobin, transferrin and ferritin concentrations, or in transferrin genetic subtypes.

Differences in adrenal steroid profile in chronic fatigue syndrome, in depression and in health

Abstract:

BACKGROUND: Hyperactivity and hypoactivity of the HPA have been forwarded as of pathophysiological relevance in major depressive disorder and chronic fatigue syndrome (CFS), respectively.

METHODS: This study examines cortisol levels in the two disorders, and also assesses levels of the adrenal androgens, dehydroepiandrosterone (DHEA) and its sulphate derivative (DHEA-S), and 17-alpha-hydroxyprogesterone; 15 subjects with CFS diagnosed according to CDC criteria, 15 subjects with DSM III-R major depression and 11 healthy subjects were compared.

RESULTS: DHEA and DHEA-S levels were significantly lower in the CFS compared to the healthy group; DHEA-S levels, but not DHEA, were lower in the depressives; cortisol and 17-alpha-hydroxyprogesterone did not differ between the three groups.

CONCLUSIONS: A potential role for DHEA, both therapeutically and as a diagnostic tool, in CFS, is suggested.

Dehydroepiandrosterone (DHEA) response to i.v. ACTH in patients with chronic fatigue syndrome

Abstract:

Previous studies have demonstrated concentrating neuroendocrinological disturbances in chronic fatigue syndrome (CFS) patients, concentrating in particular on low cortisol levels and a hypothalamic deficiency.

In order to investigate the dynamic response of the adrenal glands, we measured dehydroepiandrosterone (DHEA) in serum after adreno-corticotropic hormone (ACTH) stimulation during 60 minutes in 22 CFS-patients and 14 healthy controls.

We found normal basal DHEA levels, but a blunted serum DHEA response curve to i.v. ACTH injection. This observation adds to the large amount of evidence of endocrinological abnormalities in CFS. Relative glucocorticoid deficiency might contribute to the overall clinical picture in CFS, and could explain some of the immunological disturbances observed in this syndrome.

The value of the dehydroepiandrosterone-annexed vitamin C infusion treatment in the clinical control of chronic fatigue syndrome (CFS). I. A Pilot study of the new vitamin C infusion treatment with a volunteer CFS patient

Abstract:

A series of publications from our laboratory have indicated that the practice of megadose vitamin C drip infusion treatment enhanced the activity of endogenous glucocorticoids in such a way as to improve the clinical course of allergy and autoimmune disease-a disease entity that is known to respond to the therapeutic effect of glucocorticoids. The present paper represents an extention of our vitamin C studies, and intends to investigate the problem whether or not chronic fatigue syndrome (CFS), an acquired immunodeficiency disease, can also be counted as one of the candidate diseases for the vitamin C infusion treatment.

We prepared two kinds of vitamin C infusion sets for the clinical use: the dehydroepiandrosterone-annexed vitamin C infusion set (the new set) and the annex-free vitamin C infusion set (the old set). The new set was expected to enhance the endogenous activities of both glucocorticoids and gonadal steroids.

We followed the clinical course of a male CFS patient using the old and new vitamin C infusion sets, and with and without the oral intake of erythromycin and chloramphenico. Results obtained are as follows:

a) the observation period of a study subject covered a period of August 1995 to May 1996. Combination of pneumonia signs and dermatomyositis signs marked the onset of his CFS.

b) Old infusion treatment together with the short term antibiotics treatment was found effective for the control of pneumonia in the first stage of the disease (from August to October, 1995).

c) Signs of pneumonia recurrence gradually became eminent in the second stage of disease (from November, 1995, to January, 1996) in spite of the moderate frequency of the old treatment together with stepwise prolongation of the antibiotics treatment.

d) The alternate practice of the old and new infusion treatments together with the long-term antibiotics treatment, as conducted in the 3rd stage of disease (from February to May, 1996) led to substantial extinction of pneumonia signs (leucocytosis, tachycardia etc).

e) The practice of the new infusion treatment markedly increased the excretion of both 17-ketosteroids and 17-hydroxycorticosteroids in the urine. Evidence was also available to indicate that the dehydroepiandrosterone annex was converted to testosterone, which in turn made a contribution to the control of CFS.

f) The immunological survey of lymphocyte subsets including NK cell percent failed to find a coherent change in a study subject with CFS.

In conclusion, the above results could be taken as evidence to indicate that the new vitamin C infusion treatment effectuates the clinical control of CFS by fortifying the endogenous activities of both cortisol and testosterone. The significance of parallelism between pulmonary infection and CFS, as observed in the clinical course of the test subject, was discussed in the light of the focal infection theory of nephritis.
