A two-year follow-up study of chronic fatigue syndrome comorbid with psychiatric disorders

Abstract:

AIMS: Chronic fatigue syndrome patients often have comorbid psychiatric disorders such as major depressive disorders and anxiety disorders. However, the outcomes of chronic fatigue syndrome and the comorbid psychiatric disorders and the interactions between them are unknown. Therefore, a two-year prospective follow-up study was carried out on chronic fatigue syndrome patients with comorbid psychiatric disorders.

METHODS: A total of 155 patients who met the Japanese case definition of chronic fatigue syndrome were enrolled in this study. Comorbid psychiatric disorders were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders 4th edition criteria. Patients with comorbid psychiatric disorders received psychiatric treatment in addition to medical therapy for chronic fatigue syndrome. Seventy patients participated in a follow-up interview approximately 24 months later.

RESULTS: Of the 70 patients with chronic fatigue syndrome, 33 patients were diagnosed as having comorbid psychiatric disorders including 18 major depressive disorders. Sixteen patients with psychiatric disorders and eight patients with major depressive disorders did not fulfill the criteria of any psychiatric disorders at the follow up. As for chronic fatigue syndrome, nine out of the 70 patients had recovered at the follow up. There is no significant influence of comorbid psychiatric disorders on the outcome of chronic fatigue syndrome.

CONCLUSIONS: Chronic fatigue syndrome patients have a relatively high prevalence of comorbid psychiatric disorders, especially major depressive disorders. The outcomes of chronic fatigue syndrome and psychiatric disorders are independent. Therefore treatment of comorbid psychiatric disorders is necessary in addition to the medical treatment given for chronic fatigue syndrome.

Cognitive behavioural therapy and psycho-education for chronic fatigue syndrome in young people: reflections from the families’ perspective

Abstract:

OBJECTIVES: Recent trials have produced optimistic results for family-focussed cognitive behavioural therapy (CBT) for chronic fatigue syndrome (CFS) in young people. This study sought to examine the under-researched question of the views and experiences of patients and families who take part.

DESIGN: Semi-structured interviews and qualitative analysis were chosen in order to address clients’ perspectives in depth.

METHODS: Sixteen young people and sixteen parents who participated in a trial of CBT versus psycho-education (PE) for CFS were interviewed. Key themes were discerned using inductive thematic analysis.

RESULTS: Most families had low expectations of a cure but hope for improvement. Generally speaking, participants found both CBT and PE acceptable and helpful. Behavioural aspects of CBT (e.g. goal-setting, graded activity) were found helpful. The opportunity to gain support, recognition and validation was important. Cognitive elements of therapy were sometimes deemed inappropriate and some felt emotional aspects of CFS were not adequately addressed. Participants were ambivalent towards the extent of family involvement. Negative experiences related to the therapy setting and feeling inappropriately labeled. Most participants felt therapy was a stepping-stone towards normal life, although many felt recovery was incomplete. Very few differences were found between themes from CBT and PE participants. A notable exception was that every young person who experienced CBT described therapy as helpful, whereas the participants who strongly opposed the therapy approach had all experienced PE.

CONCLUSIONS: The detailed insights regarding families’ therapy experiences suggest areas of improvement for service delivery and topics for further investigation.

Psychiatric comorbidity in persons with chronic fatigue syndrome identified from the Georgia population

Abstract:

OBJECTIVE: To compare the prevalence of psychiatric disorders in persons with chronic fatigue syndrome (CFS) identified from the general population and a chronically ill group of people presenting with subsyndromic CFS-like illness (“insufficient symptoms or fatigue” (ISF)). Previous studies in CFS patients from primary and tertiary care clinics have found high rates of psychiatric disturbance, but this may reflect referral bias rather than true patterns of comorbidity with CFS.

METHODS: We used random digit dialing to identify unwell individuals. A detailed telephone interview identified those with CFS-like illness. These individuals participated in a 1-day clinical evaluation to confirm CFS or ISF status. We identified 113 cases of CFS and 264 persons with ISF. To identify current and lifetime psychiatric disorders, participants completed the Structured Clinical Interview for DSM-IV.

RESULTS: Sixty-four persons (57%) with CFS had at least one current psychiatric diagnosis, in contrast to 118 persons (45%) with ISF. One hundred one persons (89%) with CFS had at least one lifetime psychiatric diagnosis compared with 208 persons (79%) with ISF. Of note, only 11 persons (9.8%) with CFS and 25 persons (9.5%) with ISF reported having seen a mental healthcare specialist during the past 6 months.

CONCLUSIONS: Our findings indicate that current and lifetime psychiatric disorders commonly accompany CFS in the general population. Most CFS cases with comorbid psychiatric conditions had not sought appropriate help during the past 6 months. These results demonstrate an urgent need to address psychiatric disorders in the clinical care of CFS cases.

Use of the Temperament and Character Inventory (TCI) for assessment of personality in chronic fatigue syndrome

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) is characterized by severe and prolonged fatigue, along with a set of nonspecific symptoms and signs, such as sore throat, muscle pain, headaches, and difficulties with concentration or memory.

OBJECTIVE: The study examined whether CFS is associated with specific dimensions of Cloninger’s psychobiological model of personality.

METHOD: Personality profiles were compared between 38 CFS patients and 42 control subjects by means of the Temperament and Character Inventory (TCI).

RESULTS: The CFS group showed significantly higher scores on Harm-Avoidance and Persistence.

CONCLUSION: The current study shows a significant association between specific personality characteristics and CFS. These personality traits may be implicated in the onset and/or perpetuation of CFS and may be a productive focus for psychotherapy.

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.

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.

Change in grey matter volume cannot be assumed to be due to cognitive behavioural therapy

Comment on: Can CBT substantially change grey matter volume in chronic fatigue syndrome? [Brain. 2009]

Sir, In their reply to Dr Bramsen, De Lange et al. (2008) use a type of circular reasoning: cognitive behavioural therapy (CBT), they say, has previously been shown to be ‘effective’ for chronic fatigue syndrome (CFS) so the change they measured must be due to CBT.

First, it needs to be pointed out that CBT is far from a panacea for CFS. A recent meta-analysis (Malouff et al., 2008) of the efficacy of CBT in treating CFS found an effect size of d = 0.48 (95% CI 0.27–0.69).

In their letter, De Lange et al. (2008) refer to a review by Whiting et al. (2001) as part-evidence for their claim that CBT is effective for CFS. However, this review recommended the use of objective outcome measures e.g.

Outcomes such as ‘improvement,’ in which participants were asked to rate themselves as better or worse than they were before the intervention began, were frequently reported. However, the person may feel better able to cope with daily activities because they have reduced their expectations of what they should achieve, rather than because they have made any recovery as a result of the intervention. A more objective measure of the effect of any intervention would be whether participants have increased their working hours, returned to work or school, or increased their physical activities’.

Given one of the aims of CBT (for CFS) has been said to be ‘increased confidence in exercise and physical activity’ (O’Dowd et al.), we cannot have complete confidence that the improvements recorded in CBT trials thus far represent objective improvements [such as improvements in grey matter volume (GMV)], rather than simply being due to altering how patients answer questionnaires. An INAMI report (2006) on the use of CBT (combined with GET) in over 600 CFS patients in Belgium found that while patients reported improvements on their fatigue scores, there was negligible change on the tests of exercise capacity and there was actually a worsening of their employment status (as measured by the amount of hours worked per week), both at the end of the intervention and at follow-up.

Association of chronic fatigue syndrome and acute psychotic episode: is it coincidental?

Sir: We present a case of a woman who had suffered from chronic fatigue syndrome (CFS) for several years and was admitted for an acute psychotic episode. This association has rarely been described.

Case report. Ms. A, a 43-year-old mother of 2 children, was admitted in January 2006 with delusion and hallucinations following a period of exacerbated fatigue. She was afraid that her children would be abducted by the devil and tried to protect them. She begged her children not to get near the walls of her house for fear that the devil could erupt from the walls and take them.

Ms. A first experienced persistent fatigue 3 years before admission. Prior to this, she had been a very active woman. She had to stop working and was able to participate in only very few activities during the day. She attributed her fatigue to the overwhelming task of educating her hyperkinetic 9-year-old son.

She had a depressive episode of several months’ duration 10 years before admission, following an abortion of a pregnancy involving a malformed child. This episode had subsided without relapse. She had infectious mononucleosis 20 years before admission. A polysomnographic test 2 years before admission showed many awakenings interrupting Ms. A’s sleep pattern. She was then diagnosed with chronic fatigue syndrome according to the criteria of Holmes1 and Fukuda.2 Antidepressive medication was prescribed; it alleviated the secondary depressive symptoms but had no impact on her fatigue complaint.

During Ms. A’s hospitalization, her blood analysis results were unremarkable, excluding common organic causes of fatigue. Results of her neurologic examination at admission were normal. Her brain computed tomography (CT) scan showed frontal cortical atrophy, but neuropsychological tests failed to show major cognitive impairments.

Olanzapine was prescribed at the dosage of 15 mg/day, and her symptoms gradually subsided. She was discharged 1 month after admission, totally free of her psychotic symptoms. Her neuroleptic treatment was changed to 10 mg of aripiprazole because of excessive weight gain. Aripiprazole was as effective as olanzapine but allowed her to return to her usual weight. The treatment was gradually stopped after 1 year, with no recurrence of psychotic symptoms.

The association between CFS and psychosis has rarely been described. We are aware of only 2 other case reports. The first describes a 28-year-old man who developed CFS after mononucleosis and suffered afterward from a manic episode with psychotic characteristics.3

Neuropsychological functioning, illness perception, mood and quality of life in chronic fatigue syndrome, autoimmune thyroid disease and healthy participants

Abstract:

BACKGROUND: This study attempted to longitudinally investigate neuropsychological function, illness representations, self-esteem, mood and quality of life (QoL) in individuals with chronic fatigue syndrome (CFS) and compared them with both healthy participants and a clinical comparison group of individuals with autoimmune thyroid disease (AITD).

METHOD: Neuropsychological evaluation was administered at two time points, five weeks apart. Twenty-one individuals with CFS, 20 individuals with AITD and 21 healthy participants were matched for age, pre-morbid intelligence, education level and socio-economic status (SES). All groups also completed measures of illness perceptions, mood, self-esteem and QoL at both time points.

RESULTS: The CFS group showed significantly greater impairment on measures of immediate and delayed memory, attention and visuo-constructional ability, and reported significantly higher levels of anxiety and depression. After controlling for the effects of mood, the CFS group still demonstrated significant impairment in attention. The CFS group also reported significantly lower self-reported QoL than the AITD and healthy participants. In terms of illness perceptions, the AITD group believed that their condition would last longer, that they had more treatment control over their condition, and reported less concern than the CFS group.

CONCLUSIONS: These results suggest that the primary cognitive impairment in CFS is attention and that this is not secondary to affective status. The lower treatment control perceptions and greater illness concerns that CFS patients report may be causally related to their affective status.

Childhood trauma and risk for chronic fatigue syndrome: association with neuroendocrine dysfunction

Abstract:

CONTEXT: Childhood trauma appears to be a potent risk factor for chronic fatigue syndrome (CFS). Evidence from developmental neuroscience suggests that early experience programs the development of regulatory systems that are implicated in the pathophysiology of CFS, including the hypothalamic-pituitary-adrenal axis. However, the contribution of childhood trauma to neuroendocrine dysfunction in CFS remains obscure.

OBJECTIVES: To replicate findings on the relationship between childhood trauma and risk for CFS and to evaluate the association between childhood trauma and neuroendocrine dysfunction in CFS.

DESIGN, SETTING, AND PARTICIPANTS: A case-control study of 113 persons with CFS and 124 well control subjects identified from a general population sample of 19 381 adult residents of Georgia.

MAIN OUTCOME MEASURES: Self-reported childhood trauma (sexual, physical, and emotional abuse; emotional and physical neglect), psychopathology (depression, anxiety, and posttraumatic stress disorder), and salivary cortisol response to awakening.

RESULTS: Individuals with CFS reported significantly higher levels of childhood trauma and psychopathological symptoms than control subjects. Exposure to childhood trauma was associated with a 6-fold increased risk of CFS. Sexual abuse, emotional abuse, and emotional neglect were most effective in discriminating CFS cases from controls. There was a graded relationship between exposure level and CFS risk. The risk of CFS conveyed by childhood trauma further increased with the presence of posttraumatic stress disorder symptoms. Only individuals with CFS and with childhood trauma exposure, but not individuals with CFS without exposure, exhibited decreased salivary cortisol concentrations after awakening compared with control subjects.

CONCLUSIONS: Our results confirm childhood trauma as an important risk factor of CFS. In addition, neuroendocrine dysfunction, a hallmark feature of CFS, appears to be associated with childhood trauma. This possibly reflects a biological correlate of vulnerability due to early developmental insults. Our findings are critical to inform pathophysiological research and to devise targets for the prevention of CFS.
