On the question of infectious aetiologies for multiple sclerosis, schizophrenia and the chronic fatigue syndrome and their treatment with antibiotics

Abstract:

Close similarities in the courses of multiple sclerosis and schizophrenia laid the theoretical ground for attempting to find a common infectious aetiology for the two diseases. Chlamydia pneumoniae, which belongs to the rickettsial family of microorganisms has been linked to both diseases. It is postulated that since rickettsial microorganisms are ubiquitous in human populations they and the human species normally live in peaceful coexistence. In rare cases, for unknown reasons, varieties of them may become aggressive and pathogenic.

The kynurenic acid hypothesis of schizophrenia has attracted much attention. It also seems to have initiated a paradigmatic shift from the hitherto prevailing serological research approach to one which focuses on immunological factors.

An open clinical pilot study in which, during 2006, eight female and five male patients with psychotic symptoms were treated with a combination of antibiotics is presented, to which, in the beginning of 2007 two female patients suffering from severe and long standing chronic fatigue syndrome were added. On one year follow-up, six out of the eight female patients showed stable excellent treatment results, whereas two were rated as showing significant treatment results. Four of the five men who entered the study were suffering from chronic schizophrenia, whereas the fifth, was a case of severe acute catatonic schizophrenia.

Two of the male patients showed significant treatment results, whereas three of them were rated as having had a slight to moderate improvement. No less than three of the women had suffered their first episode of psychosis after giving birth to their first (and only) child. This finding, as these women all responded excellently to treatment with antibiotics, indicates that post partum psychosis could be regarded as an infectious complication of childbirth of, as to the causative agent, unknown aetiology. High priority ought therefore be given to initiate controlled clinical trials with antibiotic treatment of this serious condition. The otherwise promising results of the pilot study seem to warrant further and controlled clinical trials with treatment with antibiotics of patients with psychotic symptoms.

As the second patient with psychotic symptoms to enter the study, had a long standing history of chronic fatigue, where an initial treatment with the antidepressant fluoxetine had only worsened her condition, whereas ninety days of treatment with antibiotics, combined with vitamin B injections, effected a complete recovery, the author decided, when two patients with long standing and incapacitating chronic fatigue syndromes sought the clinic in February and March 2007, to include them in the study. The first of them, after sixty days of treatment with antibiotics showed excellent treatment results on follow-up one year later, whereas the second, who also took the combination of antibiotics for sixty days, was rated as having shown a significant improvement.

Visible and near-infrared spectral changes in the thumb of patients with chronic fatigue syndrome

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) patients show a persistent fatigue condition with muscle pain and impairment of concentration, memory, and sleep. Presently, the physiological basis of CFS remains unclear. In this study, spectroscopic differences in the thumb were compared between 103 CFS patients and 122 healthy controls to examine possible changes of levels of oxygenated or deoxygenated hemoglobin.

METHODS: Visible and near-infrared (Vis-NIR) spectroscopy was used to examine possible changes in the region of 600-1100 nm.

RESULTS: Vis-NIR spectra showed sharp peaks at 694, 970 and 1060 nm and broad peaks in the regions of 740-760 and 830-850 nm. As these peaks are possibly related to oxyhemoglobin, cytochrome c oxidase and water, levels of these factors were compared between the two groups. Statistical analysis of the absorbance of Vis-NIR spectra showed a significant decrease in water content, a significant increase in oxyhemoglobin content, and a significant increase in the oxidation of heme a+a(3) and copper in cytochrome c oxidase in CFS patients.

CONCLUSIONS: These changes imply accelerated blood flow and energy metabolism in the thumbs of CFS patients.

Chronic fatigue syndrome

Comment in: Graded exercise for chronic fatigue syndrome: too soon to dismiss reports of adverse reactions. [J Rehabil Med. 2010]

Comment on: Chronic fatigue syndrome: an approach combining self-management with graded exercise to avoid exacerbations. [J Rehabil Med. 2008]

 

Sir, We read with interest the special report by Nijs et al. (1), entitled “Chronic fatigue syndrome: an approach combining self-management with graded exercise to avoid exacerbations”. The paper proposes to provide an integrated model for graded exercise therapy (GET) in patients with chronic fatigue syndrome (CFS).
The authors state that current GET programmes for people with CFS exacerbate symptoms. This is a familiar and mistaken criticism of GET, often quoted from the 2001 Action for myaligic encephalomyelitis (ME) (AfME) survey, which reported that 50% of patients with CFS/ME who received graded exercise felt worse (2). A follow-up survey reported that, in many cases, exercise was being undertaken independently, without the supervision of a therapist trained to deliver GET to patients with CFS (3). In other words, it was not GET.

Illness intrusiveness in myalgic encephalomyelitis: an exploratory study

Abstract:

This study assessed the relationship between illness intrusiveness, symptoms, disability and depression in patients with myalgic encephalomyelitis (ME). Participants were 16 patients with ME and eight patients with ME plus co-morbid disorders. The patients with co-morbid disorders reported greater illness intrusiveness than the patients with ME alone, but there were no differences between the groups on the other variables. Significant correlations were found between illness intrusiveness on the one hand, and fatigue, cognitive dysfunction, disability and depression, on the other. We conclude that ME is a disabling illness, which has a major impact on various life domains.

Does hypothalamic-pituitary-adrenal axis hypofunction in chronic fatigue syndrome reflect a ‘crash’ in the stress system?

Abstract:

The etiopathogenesis of chronic fatigue syndrome (CFS) remains poorly understood. Although neuroendocrine disturbances – and hypothalamic-pituitary-adrenal (HPA) axis hypofunction in particular – have been found in a large proportion of CFS patients, it is not clear whether these disturbances are cause or consequence of the illness.

After a review of the available evidence we hypothesize that that HPA axis hypofunction in CFS, conceptualized within a system-biological perspective, primarily reflects a fundamental and persistent dysregulation of the neurobiological stress system. As a result, a disturbed balance between glucocorticoid and inflammatory signaling pathways may give rise to a pathological cytokine-induced sickness response that may be the final common pathway underlying central CFS symptoms, i.e. effort/stress intolerance and pain hypersensitivity.

This comprehensive hypothesis on HPA axis hypofunction in CFS may stimulate diagnostic refinement of the illness, inform treatment approaches and suggest directions for future research, particularly focusing on the neuroendocrine-immune interface and possible links between CFS, early and recent life stress, and depression.

Can sustained arousal explain the Chronic Fatigue Syndrome?

Abstract:

We present an integrative model of disease mechanisms in the Chronic Fatigue Syndrome (CFS), unifying empirical findings from different research traditions. Based upon the Cognitive activation theory of stress (CATS), we argue that new data on cardiovascular and thermoregulatory regulation indicate a state of permanent arousal responses – sustained arousal – in this condition.

We suggest that sustained arousal can originate from different precipitating factors (infections, psychosocial challenges) interacting with predisposing factors (genetic traits, personality) and learned expectancies (classical and operant conditioning).

Furthermore, sustained arousal may explain documented alterations by establishing vicious circles within immunology (Th2 (humoral) vs Th1 (cellular) predominance), endocrinology (attenuated HPA axis), skeletal muscle function (attenuated cortical activation, increased oxidative stress) and cognition (impaired memory and information processing). Finally, we propose a causal link between sustained arousal and the experience of fatigue.

The model of sustained arousal embraces all main findings concerning CFS disease mechanisms within one theoretical framework.

Clinical observation on the effects of Bo’s abdominal acupuncture in 40 cases of chronic fatigue syndrome

Abstract:

OBJECTIVE: To observe the curative effect of Bo’s abdominal acupuncture on chronic fatigue syndrome (CFS).

METHODS: Forty cases with CFS were treated by Bo’s abdominal acupuncture at the points for conducting qi back to its origin and 4 points on the abdomen once a day for 2 weeks. Scores for symptoms and scores for fatigue questionnaires were compared before and after treatment.

RESULTS: After treatment, the clinical symptoms of patients were differently alleviated, and scores for symptoms, mental condition and neural feeling in questionnaires on fatigue were obviously reduced (P<0.01-0.05).

CONCLUSION: Bo’s abdominal acupuncture has a good curative effect on general disease with complex symptoms, especially on lassitude, anorexia, insomnia, amnesia, diarrhea, and general pain.

The lifestyle of patients with chronic fatigue syndrome and the effect on fatigue and functional impairments

Abstract:

BACKGROUND: Little is known about the lifestyle of patients with chronic fatigue syndrome (CFS) and its influence on symptoms of CFS. The present study aimed to investigate the lifestyle of patients with CFS, and to assess whether lifestyle factors are related to fatigue and functional impairments.

METHODS: Two hundred and forty-seven patients fulfilling the Center for Disease Control criteria for CFS were included. Validated questionnaires were used to collect data on lifestyle factors, smoking, intake of alcohol, fat, fibres, fruit and vegetables, body mass index (BMI), fatigue severity and functional impairments.

RESULTS: Of the CFS patients, 23% smoked, 32% had an unhealthy BMI, and none had an unhealthy alcohol intake. A majority had an unhealthy food intake: 70% had unhealthy fat, fruit and vegetable intake, and 95% had unhealthy fibre intake. Compared with the general Dutch population, significantly fewer CFS patients were overweight. Significantly more female CFS patients abstained from alcohol, and fewer male CFS patients smoked. Unhealthy lifestyle factors were not significantly associated with fatigue severity or functional impairments.

CONCLUSIONS: CFS patients tend to lead a healthier lifestyle compared to the general Dutch population. However, no relationship was found between lifestyle factors and fatigue severity and functional impairments in CFS.

Cognitive-behavior therapy in chronic fatigue syndrome: is improvement related to increased physical activity?

Abstract:

This multiple case study of cognitive-behavioral treatment (CBT) for chronic fatigue syndrome (CFS) compared self-report and behavioral outcomes. Eleven relatively high-functioning participants with CFS received 6-32 sessions of outpatient graded-activity oriented CBT.

Self-report outcomes included measures of fatigue impact, physical function, depression, anxiety, and global change. Behavioral outcomes included actigraphy and the 6-minute walking test. Global change ratings were very much improved (n=2), much improved (n=2), improved (n=5), and no change (n=2).

Of those reporting improvement, clinically significant actigraphy increases (n=3) and decreases (n=4) were found, as well as no significant change (n=2). The nature of clinical improvement in CBT trials for high-functioning CFS patients may be more ambiguous than that postulated by the cognitive-behavioral model.

Protective effects of antidepressants against chronic fatigue syndrome-induced behavioral changes and biochemical alterations

Abstract:

Chronic fatigue syndrome (CFS) is characterized by profound fatigue, which substantially interferes with daily activities. The aim of this study was to explore the protective effects of antidepressants in an animal model of CFS in mice. Male albino mice were forced to swim individually for a period of 6-min session each for 7 days. Imipramine (10 and 20 mg/kg), desipramine (10 and 20 mg/kg) and citalopram (5 and 10 mg/kg) were administered 30 min before forced swimming test on each day.

Various behavior tests (immobility time, locomotor activity, anxiety-like behavior by plus maze and mirror chamber) followed by biochemical parameters (lipid peroxidation, reduced glutathione, catalase and nitrite level) were assessed in chronic stressed mice. Chronic forced swimming for 7 days significantly caused increase in immobility period, impairment in locomotor activity, anxiety-like behavior, and oxidative stress (raised lipid peroxidation, nitrite activity and reduced glutathione and catalase activity) as compared with naïve mice (P < 0.05).

Seven days of pretreatment with imipramine (10 and 20 mg/kg), desipramine (10 and 20 mg/kg), and citalopram (5 and 10 mg/kg) significantly reduced immobility time, improved locomotor activity and anti-anxiety effect (in both plus maze and mirror chamber test), and attenuated oxidative stress in chronic stressed mice as compared with control (chronic fatigues) (P < 0.05). These results suggested that these drugs have protective effect and could be used in the management of chronic fatigue like conditions.
