Pervasive refusal syndrome

Abstract:

We report here on a case of severe pervasive refusal syndrome. This is of interest for three reasons. Firstly, most reported cases are adolescent girls; our case is regarding an adolescent boy. Secondly, he was successfully treated at home and thirdly, the serology showed an apparent infective pre-cursor to the illness with evidence of possible autoimmune serology. A 14-year old boy deteriorated from a picture where diagnosed CFS/ME developed into Pervasive Refusal Syndrome. This included the inability to move or speak, with closed eyes, multiple tics, facial grimacing, heightened sensitivity to noise (hyperacusis) and touch (hyperaesthesia), and inability or unwillingness to eat anything except small amounts of sloppy food. Successful rehabilitation is reported. Finally the issue of nomenclature is discussed, raising the question whether Pervasive Refusal Syndrome would be better renamed in a way that does not imply that the condition is always volitional and oppositional, as this can distract focus away from an alliance between family and clinicians.

Fatigue, depressive symptoms, and anxiety from adolescence up to young adulthood: a longitudinal study

Abstract:

Fatigue is a common complaint among adolescents. We investigated the course of fatigue in females during the transition from adolescence to young adulthood and examined psychological, immunological, and life style risk factors for development of fatigue and chronic fatigue syndrome (CFS)-related symptoms.

Six hundred and thirty-three healthy females (age 14.63±1.37 years) filled out questionnaires measuring fatigue severity, depressive symptoms, anxiety, chronic fatigue syndrome (CFS)-related symptoms, sleep features, and life style characteristics at baseline and 4½ years thereafter.

Of 64 participants LPS- and CD2CD28-induced cytokine data at baseline were available. The best predictor of fatigue in young adulthood was previous fatigue severity. In participants who were non-fatigued during adolescence and who experienced a notable increase in fatigue, fatigue development was preceded by emotional problems and CFS-related complaints during adolescence. Increases as well as decreases in fatigue severity were accompanied by respectively increase and decrease in depressive symptoms and anxiety, suggesting that these symptoms cluster and co-vary over time.

Higher interferon (IFN)-γ, higher IFN-γ/interleukin (IL)-4 ratio, lower tumor necrosis factor-α and lower IL-10 at baseline were related to fatigue severity at follow up. The rise in total number of CFS-related symptoms at follow up was predicted by anxiety and decreased physical activity during adolescence. Sleep and substance use were associated with fatigue severity and anxiety and depression.

In conclusion, vulnerability to develop fatigue and associated symptoms in young adulthood can to a certain extent be identified already years before the manifestation of complaints.

Adolescent chronic fatigue syndrome: prevalence, incidence, and morbidity

Abstract:

OBJECTIVE: To determine nationwide general practitioner (GP)-diagnosed prevalence and pediatrician-diagnosed incidence rates of adolescent chronic fatigue syndrome (CFS), and to assess CFS morbidity.

DESIGN AND SETTING: We collected data from a cross-sectional national sample among GPs and prospective registration of new patients with CFS in all pediatric hospital departments in the Netherlands.

PATIENTS AND METHODS: Study participants were adolescents aged 10 to 18 years. A representative sample of GPs completed questionnaires on the prevalence of CFS in their adolescent patients. Pediatric hospital departments prospectively reported new cases of CFS in adolescent patients. For every new reported case, a questionnaire was sent to the reporting pediatrician and the reported patient to assess CFS morbidity. Prevalence was estimated through the data from GP questionnaires and incidence was estimated on the basis of cases newly reported by pediatricians from January to December 2008.

RESULTS: Prevalence was calculated as 111 per 100 000 adolescents and incidence as 12 per 100 000 adolescents per year. Of newly reported patients with CFS, 91% scored at or above cutoff points for severe fatigue and 93% at or above the cutoff points for physical impairment. Forty-five percent of patients with CFS reported >50% school absence during the previous 6 months.

CONCLUSIONS: Clinically diagnosed incidence and prevalence rates show that adolescent CFS is uncommon compared with chronic fatigue. The primary adverse impact of CFS is extreme disability associated with considerable school absence.

Chronic fatigue syndrome: a qualitative investigation of young patient’s beliefs and coping strategies

Abstract:

PURPOSE: The aim of this pilot study was to explore illness beliefs and coping strategies among adolescent patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), applying a qualitative methodology. Recent studies have explored the illness beliefs and coping strategies of adult patients with CFS/ME as possible contributing factors to the disease aetiology. These studies have mainly used quantitative methods, finding that patients often explain their illness as being due to physical causes, deny psychological causes and make use of passive and avoidant coping strategies.

METHOD:Semi-structured, in-depth interviews were conducted with nine adolescent patients with CFS/ME, thematic analysis was adapted to the material and the results were interpreted in light of theories of attribution and coping.

RESULTS: The qualitative method allowed for more complex and nuanced accounts of illness experience. The findings showed that the adolescents differ from what has previously been reported, applying more varied and flexible illness attributions and coping mechanisms than expected.

CONCLUSIONS: The heterogeneity suggested in the results has implications. We suggest three perspectives should be taken into account, both for further research and in clinical practice: (1) individual differences; (2) a developmental perspective and (3) interactive relational focus.

Fatigue In Teenagers on the interNET–the FITNET Trial. A randomized clinical trial of web-based cognitive behavioural therapy for adolescents with chronic fatigue syndrome: study protocol

Abstract:

BACKGROUND: Chronic Fatigue Syndrome (CFS) is increasingly recognized as a cause of disability and inactivity in adolescents in the Netherlands. CFS is characterized by unexplained fatigue lasting more than 6 months. Cognitive Behavioural Therapy (CBT) has proven to be effective. However, CBT availability for adolescents with CFS is limited and requires special therapeutic skills not always readily available. An alternative to the face-to-face CBT is FITNET, a web-based therapeutic program designed specifically for adolescents diagnosed with CFS, and their parents. This new CBT approach appeals to the modern youth, who grow up with internet as their main source of information. A web-based program offers the opportunity to lower thresholds for the acceptance and realization of healthcare. This treatment can be activated at any chosen time. The communication between patient and therapist can elapse asynchronously. If effective, this web-based program would greatly increase the therapeutic accessibility.

METHODS/DESIGN: A randomized clinical trial is currently conducted. One-hundred-forty adolescents aged 12-18 years diagnosed with CFS will be recruited and randomized to one of two groups: FITNET or usual care. After 6 months, the usual care group will have access to the FITNET program. Outcomes will be assessed at baseline, post intervention, and at 6 months follow-up. Primary outcome measures are school presence, fatigue severity, and physical functioning.

DISCUSSION: The FITNET study is the first randomized clinical trial which evaluates the effect of web-based CBT versus usual care in adolescents with CFS. The intervention is based on a theoretical existing model of CBT for patients with CFS. The results of this study will provide information about the possibility and efficacy of web-based CBT for adolescents with CFS and will reveal predictors of efficacy.

Adolescents with severe chronic fatigue syndrome can make a full recovery

Abstract:

The needs of children and adolescents severely affected by chronic fatigue syndrome, myalgic encephalomyelitis (CFS/ME) are currently inadequately addressed in the UK. Sadly, there are few specialists addressing the needs of these patients who are primarily bed-bound, wheelchair users or who can only leave home on an infrequent basis. Uncertainty about what to offer as well of a lack of funding may play a part. Action for Young people with ME (AYME) suggests that at least 350 severely affected children/adolescents are receiving little or inadequate care to help them overcome this debilitating illness. This case report illustrates how recovery can occur with pragmatic rehabilitation combined with a committed compassionate family based approach.

Elevated nocturnal blood pressure and heart rate in adolescent chronic fatigue syndrome

Abstract:

AIM: To compare ambulatory recordings of heart rate (HR) and blood pressure in adolescents with chronic fatigue syndrome (CFS) and healthy controls. We hypothesized both HR and blood pressure to be elevated among CFS patients.

METHODS: Forty-four CFS patients aged 12-18 years were recruited from our paediatric outpatient clinic. The controls were 52 healthy adolescents having similar distribution of age and gender. 24-h ambulatory blood pressure and HR were recorded using a validated, portable oscillometric device.

RESULTS: At night (sleep), HR, mean arterial blood pressure and diastolic blood pressure were significantly higher in CFS patients as compared with controls (p < 0.01). During daytime, HR was significantly higher among CFS patients (p < 0.05), whereas blood pressures were equal among the two groups.

CONCLUSIONS: The findings support previous experimental evidence of sympathetic predominance of cardiovascular control in adolescent CFS patients. Also, the findings prompt increased focus on cardiovascular risk assessment and suggest a possible target for therapeutic intervention.

Polymorphisms of adrenergic cardiovascular control genes are associated with adolescent chronic fatigue syndrome

Abstract:

AIM: To explore the frequency of polymorphisms in adrenergic cardiovascular control genes in adolescent with chronic fatigue syndrome (CFS) and the relation of such polymorphisms to cardiovascular variables.

METHODS: DNA from 53 patients with CFS, 12-18 years old, was analysed for five single nucleotide polymorphisms (SNPs) in the genes catechol-O-methyltransferase (COMT), the β₂ -adrenergic receptor (two SNPs), the β₁ -adrenergic receptor and the α₂(a) -adrenergic receptor. Frequencies were compared to a reference population constructed from the National Center for Biotechnology Information (NCBI) database, and associations between frequencies and autonomic cardiovascular responses during a 20° head-up tilt-test were explored.

RESULTS: For the COMT SNP Rs4680, patients with CFS had a higher frequency of the AA genotype and a lower frequency of the G containing genotypes (AG and GG), when compared to the reference sample (p = 0.046). Also, the AA genotype was associated with a smaller increase in LF/HF ratio (low-frequency:high-frequency heart rate variability ratio, an index of cardiac sympathovagal balance) during head-up tilt when compared to the AG/GG genotypes. For the β₂ -adrenergic receptor SNP Rs1042714, patients with CFS had a lower frequency of the GG genotype and a higher frequency of the genotypes containing C (CG and CC) (p = 0.044).

CONCLUSIONS: CFS might be related to polymorphisms of COMT and the β₂ -adrenergic receptor. More details of the molecular mechanisms remain to be investigated.

Blood pressure variability and closed-loop baroreflex assessment in adolescent chronic fatigue syndrome during supine rest and orthostatic stress

Abstract:

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 explore blood pressure variability and closed-loop baroreflex function at rest and during mild orthostatic stress in adolescents with CFS. We included a consecutive sample of 14 adolescents 12-18 years old with CFS diagnosed according to a thorough and standardized set of investigations and 56 healthy control subjects of equal sex and age distribution.

Heart rate and blood pressure were recorded continuously and non-invasively during supine rest and during lower body negative pressure (LBNP) of -20 mmHg to simulate mild orthostatic stress. Indices of blood pressure variability and baroreflex function (α-gain) were computed from monovariate and bivariate spectra in the low-frequency (LF) band (0.04-0.15 Hz) and the high-frequency (HF) band (0.15-0.50 Hz), using an autoregressive algorithm.

Variability of systolic blood pressure in the HF range was lower among CFS patients as compared to controls both at rest and during LBNP. During LBNP, compared to controls, α-gain HF decreased more, and α-gain LF and the ratio of α-gain LF/α-gain HF increased more in CFS patients, all suggesting greater shift from parasympathetic to sympathetic baroreflex control. CFS in adolescents is characterized by reduced systolic blood pressure variability and a sympathetic predominance of baroreflex heart rate control during orthostatic stress. These findings may have implications for the pathophysiology of CFS in adolescents.

Effects of an educational video film in fatigued children and adolescents: a randomised controlled trial

Abstract:

BACKGROUND: In many cases standard management for chronic fatigue syndrome (CFS) in children and adolescents is ineffective.

OBJECTIVE: To evaluate the efficacy of a video film intervention in preventing the development of persistent fatigue and significant school absence in fatigued children and adolescents.

DESIGN: Randomised controlled trial.

PARTICIPANTS: 91 patients with fatigue; 50 were randomly assigned to receive the intervention (video film plus usual care) and 41 to usual care only.

INTERVENTION: A video film on CFS and coping behaviour.

MAIN OUTCOME MEASURES: Self-reported fatigue severity, physical activity, motivation, concentration and school absence.

RESULTS: 79 patients had complete data at 12 months (42 in the video film and 37 in the usual care group). Mean fatigue severity and school absenteeism scores did not differ significantly, but in the intervention group the score for reduced motivation was higher (difference 2.9 (CI 0.1 to 5.7), p=0.038). 18% more patients in the intervention compared to the usual care group also had persistent fatigue with significant school absence. The odds of developing persistent fatigue and of missing >50% of school classes was 3.3 times higher in the intervention than in the usual care group (OR 3.3 (CI 1.0 to 11.3), p=0.046).

CONCLUSION:This particular video film intervention plus usual care in children and adolescents with unexplained fatigue did not prevent an unfavourable outcome and possibly had an adverse effect in that it reduced motivation and increased the incidence of persistent fatigue with significant school absence. The use of this particular film is not recommended.
