Cognitive behaviour therapy for adolescents with chronic fatigue syndrome: data are insufficient and conclusion inappropriate

Comment on: Cognitive behaviour therapy for adolescents with chronic fatigue syndrome: randomised controlled trial. [BMJ. 2005]

 

Editor—I have concerns about the design and interpretation of the study reported by Stulemeijer et al on cognitive behaviour therapy for adolescents with chronic fatigue syndrome.1 The trial arms were not matched for the number of contacts with healthcare professionals. Experience from larger and more carefully controlled randomised interventional trials of patients with chronic fatigue syndrome has clearly shown that short term improvement in symptoms is related directly to the maintenance of regular contacts with healthcare professionals rather than the therapeutic effect of the intervention itself and consequently, the improvement is not sustained once the contact is lost.2

The authors did not offer patients in their waiting list the opportunity to meet therapists regularly for five months but without having cognitive behaviour therapy. Few follow up data on patients in the intervention arm show that the specific treatment benefit was carried forward without regular contacts with the therapists. A cautious approach is essential in inferring direct benefit from cognitive behaviour therapy in the intervention arm (as opposed to short term benefit from close contact with therapists). The level of activity in some of their participants whom the authors considered to be passive remained unclear.

A feasibility study comparing two treatment approaches for chronic fatigue syndrome in adolescents

Chronic fatigue syndrome (CFS) involves severe disabling fatigue that affects physical and mental functioning.1 Reported prevalence varies between 0.05% and 2% depending on definitions and methodologies.2 3 There are significant short and long term effects on young people and their families, including long term school non-attendance.4 5 Most reported studies are not randomised, are from a variety of different clinical settings, and show variable outcomes: 5–20% being seriously incapacitated in the longer term, with larger numbers having residual symptoms.2 6–9

Family health and characteristics in chronic fatigue syndrome, juvenile rheumatoid arthritis, and emotional disorders of childhood

Abstract:

OBJECTIVE: To compare family health and characteristics in children with chronic fatigue syndrome (CFS), in juvenile rheumatoid arthritis (JRA), and emotional disorders.

METHOD: Parents of 28 children and adolescents aged 11 to 18 years with CFS, 30 with JRA, and 27 with emotional disorders (i.e., anxiety and/or depressive disorders) were recruited from specialty clinical settings and completed interviews and questionnaires assessing family health problems, parental mental distress, illness attitudes, and family burden of illness.

RESULTS: Parents of children with CFS were significantly more likely than those of children with JRA to report a history of CFS-like illness, high levels of mental distress, and a tendency to experience functional impairment in response to physical symptoms. Families of children with CFS were characterized by significantly greater emotional involvement and reported greater family burden related to the child’s illness in comparison with families of children with JRA.

CONCLUSIONS: CFS in childhood and adolescence is associated with higher levels of parental CFS-like illness, mental distress, emotional involvement, and family illness burden than those observed in association with JRA, a chronic pediatric physical illness.

Cognitive behaviour therapy for adolescents with chronic fatigue syndrome: randomised controlled trial

Erratum in: BMJ. 2005 Apr 9;330(7495):820.

 

Abstract:

OBJECTIVE: To evaluate the efficacy of cognitive behaviour therapy for adolescents aged 10-17 years with chronic fatigue syndrome.

DESIGN: Randomised controlled trial.

SETTING: Department of child psychology.

PARTICIPANTS: 71 consecutively referred patients with chronic fatigue syndrome; 36 were randomly assigned to immediate cognitive behaviour therapy and 35 to the waiting list for therapy.

INTERVENTION: 10 sessions of therapy over five months. Treatment protocols depended on the type of activity pattern (relatively active or passive). All participants were assessed again after five months.

MAIN OUTCOME MEASURES: Fatigue severity (checklist individual strength), functional impairment (SF-36 physical functioning), and school attendance.

RESULTS: 62 patients had complete data at five months (29 in the immediate therapy group and 33 on the waiting list). Patients in the therapy group reported significantly greater decrease in fatigue severity (difference in decrease on checklist individual strength was 14.5, 95% confidence interval 7.4 to 21.6) and functional impairment (difference in increase on SF-36 physical functioning was 17.3, 6.2 to 28.4) and their attendance at school increased significantly (difference in increase in percentage school attendance was 18.2, 0.8 to 35.5). They also reported a significant reduction in several accompanying symptoms. Self reported improvement was largest in the therapy group.

CONCLUSION: Cognitive behaviour therapy is an effective treatment for chronic fatigue syndrome in adolescents.

Sociodemographic and symptom correlates of fatigue in an adolescent primary care sample

Abstract:

PURPOSE: To describe the prevalence of prolonged fatigue, chronic fatigue syndrome (CFS)-like illness, and associated symptom patterns in adolescents attending primary care.

METHODS: The design was cross-sectional. A questionnaire designed by the authors assessing fatigue and associated symptoms was administered to 901 adolescents (aged 11-18 years) attending 12 primary care clinics in the Chicago area. Prevalence rates for prolonged fatigue and CFS-like illness were calculated. Univariate comparisons involving sociodemographic data and fatigue severity were made between adolescents with and without prolonged fatigue, and sociodemographic and symptom predictors of prolonged fatigue were identified using logistic regression analysis.

RESULTS: Prolonged fatigue (> or = 1 month) occurred at a rate of 8.0% and CFS-like illness occurred at a rate of 4.4%. Adolescents with prolonged fatigue were significantly older and also reported greater fatigue severity than those without fatigue. Findings from logistic regression indicated that, in addition to increasing age, headaches, muscle pains, fever, and fatigue made worse by exercise were significantly associated with prolonged fatigue.

CONCLUSIONS: Abnormal fatigue is a disabling and prevalent condition in adolescents in primary care. It is associated with a number of additional symptoms, many of which may have viral origins.

Outpatient rehabilitative treatment of chronic fatigue syndrome (CFS/ME)

Abstract:

AIMS: To assess the outcome of outpatient multidisciplinary rehabilitative treatment (graded activities/exercise programme, family sessions, and supportive care) compared with supportive care alone for children and adolescents with chronic fatigue syndrome (CFS/ME).

METHODS: Fifty six young people (aged 9-17 years) with CFS/ME by standard criteria were followed up for 3-24 months. All subjects received supportive care. Families additionally opted to either enter the rehabilitation programme (supportive care plus graded activities/exercise programme and family sessions) or have no additional treatment.

RESULTS: Twenty two (39%) subjects had supportive care alone and 26 (46%) entered the programme. Treatment groups were comparable at baseline in terms of age, severity and duration of illness, Wellness score, and school attendance. At end of follow up, those in the programme group had significantly higher Wellness score and school attendance than those having supportive care alone. The programme significantly reduced the overall severity of illness: after the programme, 43% had complete resolution of CFS/ME compared to only 4.5% of those having supportive care alone. The presence of depressed mood and family beliefs about the aetiology of CFS/ME were not significantly associated with outcomes.

CONCLUSIONS: Outpatient rehabilitative treatment offers significant potential to improve the prognosis of CFS/ME in childhood and adolescence.

Chronic fatigue syndrome and other fatiguing illnesses in adolescents: a population-based study

Abstract:

PURPOSE: To estimate the prevalence of chronic fatigue syndrome (CFS) and describe characteristics of other fatiguing illnesses in adolescents (aged 12 through 17 years).

METHODS: We conducted a random digit dialing survey of the residents of Wichita, Kansas. Adults identified fatigued adolescents in the household and answered questions relating to the child’s health. Selected adolescents were invited to attend a clinic with a parent/guardian. After clinical evaluation they were classified as CFS or another fatigue state as defined in the 1994 CFS definition. Annual telephone interviews and clinical evaluations monitored subjects’ fatigue status. Data were analyzed using the Kruskal-Wallis test, the Mantel-Haenszel test, and the exact McNemar test.

RESULTS: The survey contacted 34,018 households with 90,316 residents. Of 8586 adolescents, 138 had fatigue for > or =1 month and most (107 or 78%) had chronic fatigue (> or =6 months) at some point during the 3-year follow-up. Twenty-eight had exclusionary diagnoses. Thirty-one were considered to have a CFS-like illness and were invited for clinical evaluation. Eleven agreed to participate and none met the CFS case definition. The baseline weighted prevalence of CFS-like illness was 338 per 100,000. Significant differences existed between parental and adolescents’ descriptions of illness.

CONCLUSIONS: The prevalence of CFS among adolescents was considerably lower than among adults. Evaluation of CFS in adolescents must consider both parent and patient perception of fatigue and other illnesses that might explain the symptom complex.

Prevalence of chronic disabling fatigue in children and adolescents

Abstract:

BACKGROUND: The epidemiology of chronic fatiguing illnesses in young people is poorly understood.

AIMS: To estimate the lifetime prevalence of different definitions of chronic fatigue in 8- to 17-year-olds.

METHOD: Participants came from two population-based twin series. Parents completed self-report questionnaires that inquired whether either child had ever experienced more than a few days of disabling fatigue. Telephone interviews were undertaken for individuals who had experienced such an episode.

RESULTS: Questionnaires were returned by 1468 families (65% response rate) and telephone interviews were undertaken regarding 99 of the 129 subjects (77%) who had experienced fatigue. The lifetime prevalence estimates ranged from 2.34% (95% CI 1.75-2.94) for disabling fatigue lasting 3 months to 1.29% (95% CI 0.87-1.71) for a disorder resembling adult operationally defined chronic fatigue syndrome.

CONCLUSIONS: From the age of 11 years, young people have similar rates and types of chronic fatiguing illnesses to adults.

Impairment and coping in children and adolescents with chronic fatigue syndrome: a comparative study with other paediatric disorders

Abstract:

BACKGROUND: Functional impairment is a key feature of chronic fatigue syndrome (CFS) of childhood.

AIM: To compare impairment, illness attitudes and coping mechanisms in childhood CFS and in other paediatric disorders.

METHOD: Participants were 28 children and adolescents with CFS, 30 with juvenile idiopathic arthritis (JIA) and 27 with emotional disorders (ED). The measures used were interviews with children and parents, with detailed enquiry on impairment, including the Functional Disability Inventory (FDI), Illness Attitudes Scales (IAS), and Kidcope to measure coping styles in relation to common problems, illness and disability.

RESULTS: Children with CFS reported significantly more illness impairment, especially in school attendance, than those with JIA and ED. They had higher ‘worry about illness’ scores on the IAS. On the Kidcope they named school issues (work, expectations, attendance) as illness- or disability-related problems more than the other two groups. Fewer CFS participants reported using problem solving as a strategy to cope with illness and disability than with other problems in their lives. More in the CFS than in the JIA group used emotional regulation to cope with illness and disability. Fewer in the CFS than in the ED groups used social withdrawal to cope with illness and self-criticism for disability, but more used resignation to cope with disability.

CONCLUSION: Severe illness-related impairment, particularly through school non-attendance, and high levels of illness-related school concerns appear specific to CFS. CFS may also have characteristically high levels of generalised illness worry and particular styles of coping with illness and disability.

Chronic fatigue syndrome in adolescents: a follow-up study

Abstract:

OBJECTIVES: To compare the frequency of persistent symptoms up to 8 years after illness onset in adolescents diagnosed as having chronic fatigue syndrome, idiopathic chronic fatigue, and unexplained fatigue for less than 6 months, and to determine if hospital admission is associated with outcome.

DESIGN: A cohort study using questionnaire follow-up.

SETTING: A tertiary referral hospital.

PATIENTS: Consecutive adolescents referred for assessment of persistent fatigue were identified and retrospectively divided into 3 groups according to the diagnostic criteria for chronic fatigue syndrome and idiopathic chronic fatigue.

INTERVENTION: A questionnaire was designed and administered by telephone at a mean of 4.57 years after the initial examination.

MAIN OUTCOME MEASURE: The persistence of self-reported symptoms was compared with respect to patient group and admission.

RESULTS: Outcome data were obtained for 34 (69%) of the 49 eligible subjects. Twenty-five percent of the chronic fatigue syndrome group showed near to complete improvement, 31% showed partial improvement, and 44% showed no improvement. The idiopathic chronic fatigue group had near to complete recovery in 50%, partial in 10%, and no improvement in 40%. Those with unexplained fatigue for less than 6 months had all recovered. There was no difference between the outcome of the subjects admitted to the hospital and those managed as outpatients.

CONCLUSIONS: Adolescents with less than 6 months of fatigue have a good outcome. Unexplained fatigue lasting more than 6 months has a similar outcome regardless of the presence of minor criteria for chronic fatigue syndrome.
