Adolescent offspring of mothers with chronic fatigue syndrome

Abstract:

PURPOSE: The goal of this study was to determine whether adolescent offspring of mothers with chronic fatigue syndrome(CFS) have higher prevalence of CFS and report more fatigue, greater pain sensitivity, more sleep problems, and poorer cardiopulmonary fitness in comparison with offspring with no exposure to maternal CFS.

METHODS: A total of 26 adolescent offspring of 20 mothers diagnosed with CFS were compared with 45 adolescent offspring of 30 age-matched healthy control mothers. Study measures included structured interviews and medical and laboratory examinations for CFS; tender point examination; maximum oxygen uptake and perceived exertion; dolorimetry pain ratings; and questionnaires on fatigue severity and sleepiness.

RESULTS: In comparison with offspring of healthy mothers, those exposed to mothers with CFS reported higher prevalence of fatigue of at least 1-month duration (23% vs. 4%), fatigue of 6 months or longer (15% vs. 2%), and met criteria for CFS (12% vs. 2%), although these differences only approached statistical significance. CFS and healthy mothers differed on almost all study outcomes, but offspring groups did not differ on measures of current fatigue severity, pain sensitivity, sleep, mean number of tender points, and cardiopulmonary fitness.

CONCLUSIONS: The higher prevalence of fatiguing states in offspring of CFS mothers, despite the lack of statistical significance, suggests that familial factors may potentially play a role in developing chronically fatiguing states. Alternately, perturbations in pain sensitivity and cardiopulmonary fitness may be consequences of CFS. Future studies should focus on examining the impact of maternal CFS and associated disability on psychosocial functioning of offspring.

Family-focused cognitive behaviour therapy versus psycho-education for chronic fatigue syndrome in 11- to 18-year-olds: a randomized controlled treatment trial

Abstract:

BACKGROUND: Only one previous randomized controlled trial (RCT) has examined the efficacy of cognitive behaviour therapy (CBT) for chronic fatigue syndrome (CFS) in children. The aim of this study was to compare family-focused CBT with psycho-education for CFS in adolescents.

METHOD: Sixty-three 11- to 18-year-olds (43 girls, 20 boys) with CFS were randomly assigned to either family-focused CBT or psycho-education delivered over 6 months. School attendance was the main outcome, which was assessed at the end of treatment and at 3, 6 and 12 months follow-up.

RESULTS: At the main outcome point (the 6-month follow-up) both groups had improved similarly. However, although those who received family-focused CBT were attending school for longer than those who received psycho-education, at discharge from treatment and at 3 months follow-up, they improved less quickly across the follow-up period.

CONCLUSIONS: Adolescents with CFS get back to school more quickly after family-focused CBT. This is important as they are at a crucial stage of their development. However, the finding that psycho-education was as effective as family-focused CBT at 6 and 12 months follow-up has important implications for health service delivery.

Chronic fatigue syndrome in adolescents: do parental expectations of their child’s intellectual ability match the child’s ability?

Abstract:

OBJECTIVE: This cross-sectional study aimed to measure the discrepancy between actual and perceived IQ in a sample of adolescents with CFS compared to healthy controls. We hypothesized that adolescents with CFS and their parent would have higher expectations of the adolescent’s intellectual ability than healthy adolescents and their parent.

METHODS: The sample was 28 CFS patients and 29 healthy controls aged 11-19 years and the parent of each participant. IQ was assessed using the AH4 group test of general intelligence and a self-rating scale which measured perceived IQ.

RESULTS: Parents’ perceptions of their children’s IQ were significantly higher for individuals with CFS than healthy controls.

CONCLUSIONS: High expectations may need to be addressed within the context of treatment.

Chronic fatigue syndrome after infectious mononucleosis in adolescents

Abstract:

OBJECTIVE: The goal was to characterize prospectively the course and outcome of chronic fatigue syndrome in adolescents during a 2-year period after infectious mononucleosis.

METHODS: A total of 301 adolescents (12-18 years of age) with infectious mononucleosis were identified and screened for nonrecovery 6 months after infectious mononucleosis by using a telephone screening interview. Nonrecovered adolescents underwent a medical evaluation, with follow-up screening 12 and 24 months after infectious mononucleosis. After blind review, final diagnoses of chronic fatigue syndrome at 6, 12, and 24 months were made by using established pediatric criteria.

RESULTS: Six, 12, and 24 months after infectious mononucleosis, 13%, 7%, and 4% of adolescents, respectively, met the criteria for chronic fatigue syndrome. Most individuals recovered with time; only 2 adolescents with chronic fatigue syndrome at 24 months seemed to have recovered or had an explanation for chronic fatigue at 12 months but then were reclassified as having chronic fatigue syndrome at 24 months. All 13 adolescents with chronic fatigue syndrome 24 months after infectious mononucleosis were female and, on average, they reported greater fatigue severity at 12 months. Reported use of steroid therapy during the acute phase of infectious mononucleosis did not increase the risk of developing chronic fatigue syndrome.

CONCLUSIONS: Infectious mononucleosis may be a risk factor for chronic fatigue syndrome in adolescents. Female gender and greater fatigue severity, but not reported steroid use during the acute illness, were associated with the development of chronic fatigue syndrome in adolescents. Additional research is needed to determine other predictors of persistent fatigue after infectious mononucleosis.

Promising outcomes of an adolescent chronic fatigue syndrome inpatient programme

Abstract:

INTRODUCTION: Chronic fatigue syndrome (CFS) is a condition of prolonged and disabling fatigue, which is accompanied by characteristic constitutional and neuropsychiatric symptoms. In children and adolescents, this condition occurring at a developmentally vulnerable time adds to the disability affecting self-concept, autonomy, body image, socialisation, sexuality and academic problems. This case series looks at the effects of a graded exercise programme on physical outcomes, fatigue and mental state in an adolescent population.

METHODS: Data sets from 16 adolescents who completed combined exercise training as part of the 4-week inpatient intensive CFS programme at the Austin Hospital, Melbourne were analysed. All patients completed an exercise assessment and three questionnaires before beginning any training. A paediatrician (LL) confirmed the diagnosis according to the Fukuda criteria in all patients. Exercise was carefully supervised and prescribed daily by an exercise physiologist (BG) according to each individual’s ability and response with the basic aim of increasing exercise tolerance and improving muscle strength and endurance.

RESULTS: There was an 18% improvement in volitional time to fatigue (P= 0.02) and 17% improvement in peak oxygen uptake (VO(2peak)) (P= 0.01). Upper body strength and function improved with a remarkable 70% increase in the number of push-ups. Fatigue severity was reported to improve by 13% (P= 0.01) and depression index improved significantly by 42% (P= 0.02).

CONCLUSIONS: The significance of these improvements cannot be underestimated as an improvement in physical capacity through increased time to fatigue and less severe fatigue allows adolescents to resume school, social and family activities.

Anxiety in children with CFS/ME

Abstract:

Anxiety symptoms are commonly described in children with chronic fatigue syndrome or myalgic encephalopathy (CFS/ME) but to date there has been little information on the type of anxiety children experience or the relationship between anxiety and school attendance, disability or fatigue.

The aim of this study was to first describe the prevalence and type of anxiety symptoms in children with CFS/ME compared with a normal European population, and secondly to investigate the association of anxiety symptoms with age, gender, school attendance, fatigue, and physical function in paediatric CFS/ME.

Data were prospectively collected on children and young people with CFS/ME referred to a large specialist CFS/ME service. One hundred and sixty-four children with CFS/ME had complete data for the Spence Children’s Anxiety Scale. Teenage girls had the highest rates of total anxiety symptoms with 38% (95% CI 27-49) over the cut off (top 10% of normal European population) and significantly higher rates of symptoms in each subscale.

Younger girls were more likely to score over the cut off in separation anxiety (37%, 19-40) and social phobia (39%, 25-47). There was no evidence of association between total anxiety symptoms and: time at school, time to assessment, pain or age. Associations with fatigue and physical function were attenuated when adjusted for other variables. Although anxiety symptoms are high in CFS/ME, particularly in teenage girls, it does not appear to be associated with school attendance or other measures of disability. Separation anxiety and social phobia were the most clearly elevated in paediatric CFS/ME.

Vaccination as teenagers against meningococcal disease and the risk of the chronic fatigue syndrome

Abstract:

The etiology of chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) is unknown. In Norway, a vaccine against Neisseria meningitides group B was administered to teenagers in 1988–1989 in a protection trial. In order to estimate the relative risk of CFS/ME according to vaccine history, we conducted a case-control study in 2007, with 201 cases diagnosed at one of two hospitals and 389 controls. The adjusted odds ratio for CFS/ME was 1.06 (95% CI: 0.67-1.66) for subjects who received the active vaccine contrasted to subjects who did not. Using this design, no statistically significant association between vaccination against meningococcal disease in teenagers and occurrence of CFS/ME could be observed.

Efficacy of cognitive behavioral therapy for adolescents with chronic fatigue syndrome: long-term follow-up of a randomized, controlled trial

Abstract:

OBJECTIVES: The purpose of this work was to assess the long-term outcome of adolescents with chronic fatigue syndrome who received cognitive behavioral therapy and to determine the predictive value of fatigue severity and physical impairments of the adolescent and the fatigue severity of the mother at baseline for the outcome of the treatment at follow-up.

PATIENTS AND METHODS: Sixty-six adolescent patients with chronic fatigue syndrome who previously participated in a randomized, controlled trial that showed that cognitive behavioral therapy was more effective than a waiting-list condition in reducing fatigue and improving physical functioning were contacted for a follow-up assessment. Fifty participants of the follow-up study had received cognitive behavioral therapy for chronic fatigue syndrome (32 formed the cognitive behavioral therapy group in the original trial, and 18 patients received cognitive behavioral therapy after the waiting period). The remaining 16 patients had refused cognitive behavioral therapy after the waiting period. The main outcome measures were fatigue severity (Checklist Individual Strength), physical functioning (Short-Form General Health Survey), and school attendance.

RESULTS: Data were complete for 61 patients at follow-up (cognitive behavioral therapy group: 47 patients; no-treatment group: 14 patients). The mean follow-up time was 2.1 years. There was no significant change in fatigue severity between posttreatment and follow-up in the cognitive behavioral therapy group. There was a significant further increase in physical functioning and school attendance (10% increase). The adolescents in the cognitive behavioral therapy group were significantly less fatigued and significantly less functionally impaired and had higher school attendance at follow-up than those in the no-treatment group. Fatigue severity of the mother was a significant predictor of treatment outcome.

CONCLUSIONS: The positive effects of cognitive behavioral therapy in adolescents with chronic fatigue syndrome are sustained after cognitive behavioral therapy. Higher fatigue severity of the mother predicts lower treatment outcome in adolescent patients.

Enhanced vagal withdrawal during mild orthostatic stress in adolescents with chronic fatigue

Abstract:

BACKGROUND: Hemodynamic abnormalities have been documented in the chronic fatigue syndrome (CFS), indicating functional disturbances of the autonomic nervous system responsible for cardiovascular regulation. The aim of this study was to investigate autonomic heart rate control during mild orthostatic stress in adolescents with CFS.

METHODS: A total of 14 CFS patients and 56 healthy controls having equal distribution of age and gender underwent lower body negative pressure (LBNP) of horizontal line 20 mmHg. The RR interval (RRI) was recorded continuously, and spectral power densities were computed in the low-frequency (LF) band (0.04-0.15 Hz) and the high-frequency (HF) band (0.15-0.50 Hz) from segments of 120-second length, using an autoregressive algorithm. In addition, the time-domain indices SDNN, pNN50, and r-MSSD were computed.

RESULTS: At rest, CFS had lower RRI than controls (P < 0.05), but indices of variability were similar in the two groups. During LBNP, compared to controls, CFS patients had lower normalized and absolute HF power and r-MSSD (P < 0.05), and higher RRI (P < 0.001), normalized LF power and LF/HF (P < 0.05).

CONCLUSIONS: During mild orthostatic stress, adolescents with CFS appear to have enhanced vagal withdrawal, leading to a sympathetic predominance of heart rate control compared to controls. Possible underlying mechanisms include hypovolemia and abnormalities of reflex mechanisms.
