Adolescent and parent factors related to fatigue in paediatric multiple sclerosis and chronic fatigue syndrome: A comparative study

Abstract:

BACKGROUND: Fatigue is a disabling, poorly understood symptom in children and adolescents with multiple sclerosis (caMS), for which effective treatments are lacking. In paediatric Chronic Fatigue Syndrome (CFS), effective psychological interventions have been developed based on psychosocial factors associated with fatigue. This study aimed to identify potentially modifiable factors of fatigue in caMS by comparing caMS, adolescents with CFS, healthy adolescents and their parents on measures of fatigue, psychosocial factors, and neurocognitive functioning.

METHODS: 175 participants including 30 caMS (15 fatigued, 15 non-fatigued), 30 adolescents with CFS, 30 healthy controls, and their parents were compared on measures of self- and parent-reported fatigue, adolescent and parent cognitive behavioural responses to symptoms, sleep, psychological difficulties, parental distress and objectively measured neurocognitive functioning.

RESULTS: Fatigue severity, functional impairment and cognitive behavioural responses to symptoms were equivalent in fatigued caMS and adolescents with CFS, and were significantly higher than in healthy controls and non-fatigued caMS. Neurocognitive functioning was impaired in both caMS groups, but was normal in adolescents with CFS and healthy controls. No between-group differences were identified in adolescent sleep behaviour or psychological difficulties. Parents of all illness groups had more unhelpful cognitions than parents of healthy controls. Psychological distress was elevated in parents of both fatigued groups.

CONCLUSIONS: Fifty percent of caMS reported clinically significant fatigue. Similarities between adolescent and parent cognitive behavioural factors in fatigued caMS and adolescents with CFS suggest important potential targets for intervention. Both fatigued and non-fatigued caMS had cognitive difficulties, suggesting that fatigue may need targeted intervention.

Associations between clinical symptoms, plasma norepinephrine and deregulated immune gene networks in subgroups of adolescent with Chronic Fatigue Syndrome

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) is one of the most important causes of disability among adolescents while limited knowledge exists on genetic determinants underlying disease pathophysiology.

METHODS: We analyzed deregulated immune-gene modules using Pathifier software on whole blood gene expression data (29 CFS patients, 18 controls). Deconvolution of immune cell subtypes based on gene expression profile was performed using CIBERSORT. Supervised consensus clustering on pathway deregulation score (PDS) was used to define CFS subgroups. Associations between PDS and immune, neuroendocrine/autonomic and clinical markers were examined. The impact of plasma norepinephrine level on clinical markers over time was assessed in a larger cohort (91 patients).

RESULTS: A group of 29 immune-gene sets was shown to differ patients from controls and detect subgroups within CFS. Group 1P (high PDS, low norepinephrine, low naïve CD4+ composition) had strong association with levels of serum C-reactive protein and Transforming Growth Factor-beta. Group 2P (low PDS, high norepinephrine, high naïve CD4+ composition) had strong associations with neuroendocrine/autonomic markers. The corresponding plasma norepinephrine level delineated 91 patients into two subgroups with significant differences in fatigue score.

CONCLUSION: We identified 29 immune-gene sets linked to plasma norepinephrine level that could delineate CFS subgroups. Plasma norepinephrine stratification revealed that lower levels of norepinephrine were associated with higher fatigue. Our data suggests potential involvement of neuro-immune dysregulation and genetic stratification in CFS.

No evidence found for an increased risk of long-term fatigue following human papillomavirus vaccination of adolescent girls

Abstract:

INTRODUCTION: In 2013, the Netherlands Pharmacovigilance Center Lareb published an overview of reports of long-lasting fatigue following bivalent HPV-vaccination (2vHPV). After an update of this overview in 2015, concerns regarding the safety of 2vHPV was picked up by the media, which led to further reports of long-lasting fatigue. Therefore, the Dutch National Institute for Public Health and the Environment (RIVM) investigated a possible association between HPV-vaccination and long-term fatigue.

METHODS: In this retrospective cohort study conducted in the Integrated Primary Care Information database, we investigated the occurrence of chronic fatigue syndrome (CFS), fatigue ≥6 months and 3-6 months in all girls born in 1991-2000 during the follow-up period January 1st 2007-December 31st 2014 (2007-2008 pre-vaccination and 2009-2014 post-vaccination). Patients with certain fatigue ≥6 m were asked for consent to link their primary care information with vaccination data. Incidence rates per 10,000 person years (PY) for 12-16-year-old girls were compared between pre- and post-HPV-vaccine era. A self-controlled case series (SCCS) analysis was performed using consenting vaccinated cases. A primary high-risk period of 12 months after each dose was defined.

RESULTS: The cohort consisted of 69,429 12-16-year-old girls accounting for 2758 PY pre-vaccination and 57,214 PY post-vaccination. Differences between pre- and post-vaccination incidences (CFS: 3.6 (95% CI 0.5-25.7)/10,000 PY and 0.9 (0.4-2.1); certain fatigue ≥6 m: 7.3 (1.8-29.0) and 19.4 (16.1-23.4); certain fatigue 3-6 m: 0.0 and 16.6 (13.6-20.3), respectively) were not statistically significant. SCCS analyses in 16 consenting vaccinated cases resulted in an age-adjusted RR of 0.62 (95%CI 0.07-5.49).

CONCLUSIONS: Fatigue ≥6 m and 3-6 m was frequently found among adolescent girls, but CFS was rarely diagnosed. No statistically significant increased incidence rates were found post-vaccination compared to similar age groups of girls pre-vaccination. The SCCS analysis included a low number of cases but revealed no elevated risk of certain fatigue ≥6 m in the high-risk period.

Predictors of chronic fatigue in adolescents six months after acute Epstein-Barr virus infection: a prospective cohort study

Abstract:

INTRODUCTION: Acute Epstein-Barr virus (EBV) infection is a trigger of chronic fatigue and Chronic Fatigue Syndrome (CFS). This study investigated baseline predictors of chronic fatigue six months after an acute EBV infection.

MATERIALS AND METHODS: A total of 200 adolescents (12-20 years old) with acute EBV infection were assessed for 149 possible baseline predictors and followed prospectively. We performed linear regression to assess possible associations between baseline predictors and fatigue (Chalder Fatigue Questionnaire total score) six months after the acute EBV infection. A total of 70 healthy controls were included for cross-sectional reference. This study is part of the CEBA-project (Chronic fatigue following acute Epstein-Barr virus infection in adolescents).

RESULTS: In the final multiple linear regression model, fatigue six months after acute EBV infection was significantly and independently predicted by the following baseline variables (regression coefficient B[95% CI]): Sensory sensitivity (0.8[0.09 to 1.6]), pain severity (0.2[0.02 to 0.3]), functional impairment (1000 steps/day) (-0.3[-0.5 to -0.08]), negative emotions (anxiety) (0.4[0.2 to 0.6]), verbal memory (correct word recognition) (1.7[0.1 to 3.3]), plasma C-reactive protein (2.8[1.1 to 4.4] for CRP values >0.86) and plasma Vitamin B12 (-0.005[-0.01 to -0.001]).

CONCLUSIONS: Development of fatigue after acute EBV infection is to a larger extent predicted by baseline variables related to symptoms and functions than to baseline variables reflecting infectious and immune processes.

Using the internet to cope with chronic fatigue syndrome/myalgic encephalomyelitis in adolescence: a qualitative study

Abstract:

BACKGROUND: Adolescents are increasingly using online resources for health purposes. Previous studies suggest that online provision of information about chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) is neither balanced nor consistent with evidence-based practice. However, little is known about how adolescents with CFS/ME use the internet for their condition and whether this is helpful or harmful.

METHODS: Nine indepth, semistructured, qualitative interviews were conducted with young people (aged 12-17) recruited from a specialist paediatric CFS/ME service. Interviews explored the types of online resources accessed, motivations for doing so and how resource use related to patterns of coping.

RESULTS: Around the time of diagnosis, participants focused on gathering facts about CFS/ME and therefore used official resources (eg, National Health Service sites) that were considered reliable. This transitioned to exploring patient-led and peer-led spaces: health forums, Facebook and YouTube. Participants accessed these regularly, over the long term, and valued these sites for the personal stories, emotional content and interactive technology. Patient-led and peer-led sites supported coping, encouraging active behavioural management, providing social support and addressing stigmatised aspects of the condition. CFS/ME put a strain on normal adolescent life, such as identity and friendships. Online resources allowed participants to adapt and maintain a sense of normality.

CONCLUSIONS: Adolescents who use the internet find online resources helpful in seeking information and social support for their condition. Healthcare services should improve their online resources to meet the needs of younger users, providing evidence-based content in ways that are relevant to adolescents and that can meet the needs for social support, as well as providing information.

Two-Year Follow-Up of Impaired Range of Motion in Chronic Fatigue Syndrome

Abstract:

OBJECTIVE: To measure changes in range of motion (ROM) over time in a cohort of 55 adolescents and young adults with chronic fatigue syndrome and to determine whether changes in ROM correlated with changes in health-related quality of life.

STUDY DESIGN: Participants underwent a standardized examination of 11 areas of limb and spine ROM at baseline and at 3- to 6-month intervals for 2 years, resulting in a ROM score that ranged from 0 (normal throughout) to 11 (abnormal ROM in all areas tested). We measured the time until the ROM score was ≤2 (the score in healthy age-matched controls). Change in ROM was measured by subtracting the 24-month from the baseline ROM score and by summing the degrees of change in the 10 tests with continuous outcomes. Health-related quality of life was measured using the Pediatric Quality of Life Inventory 4.0 (PedsQL).

RESULTS: The mean age at enrollment was 16.5 years (range 10-23). Two-year follow-up was available for 53 (96%). The proportion with a ROM score of >2 fell gradually over 2 years, from 78% at entry to 20% at 24 months (P < .001). ROM scores improved from a median of 5 at entry to 2 at 24 months (P < .001). The change in the summed degrees of improvement in ROM correlated positively with improvement in the PedsQL physical function subscale (r = 0.30; P < .03).

CONCLUSIONS: In association with multimodal therapy, young people with chronic fatigue syndrome experienced progressively less impairment in ROM over 2 years, correlating with improvements in the physical function subscale of the PedsQL.

SEID diagnostic criteria applied on an adolescent cohort: evaluation of subgroup differences and prognostic utility

Systemic exertion intolerance disease diagnostic criteria applied on an adolescent chronic fatigue syndrome cohort: evaluation of subgroup differences and prognostic utility

Abstract:

OBJECTIVE: Existing case definitions for chronic fatigue syndrome (CFS) all have disputed validity. The present study investigates differences between adolescent patients with CFS who satisfy the systemic exertion intolerance disease (SEID) diagnostic criteria (SEID-positive) and those who do not satisfy the criteria (SEID-negative).

METHODS: 120 adolescent patients with CFS with a mean age of 15.4 years (range 12-18 years) included in the NorCAPITAL project (ClinicalTrials ID: NCT01040429) were post-hoc subgrouped according to the SEID criteria based on a comprehensive questionnaire. The two subgroups were compared across baseline characteristics, as well as a wide range of cardiovascular, inflammatory, infectious, neuroendocrine and cognitive variables. Data from 30-week follow-up were used to investigate prognostic differences between SEID-positive and SEID-negative patients.

RESULTS: A total of 45 patients with CFS were SEID-positive, 69 were SEID-negative and 6 could not be classified. Despite the fact that clinically depressed patients were excluded in the NorCAPITAL project, the SEID-positive group had significantly higher score on symptoms suggesting a mood disorder (Mood and Feelings Questionnaire): 23.2 vs 13.4, difference 9.19 (95% CI 5.78 to 12.6). No other baseline characteristics showed any group differences. When accounting for multiple comparisons, there were no statistically significant differences between the groups regarding cardiovascular, inflammatory, infectious, neuroendocrine and cognitive variables. Steps per day and Chalder Fatigue Questionnaire at week 30 showed no differences between the groups.

CONCLUSION: The findings question the discriminant and prognostic validity of the SEID diagnostic criteria in adolescent CFS, and suggest that the criteria tend to select patients with depressive symptoms.

‘It’s like being a slave to your own body in a way’: a qualitative study of adolescents with chronic fatigue syndrome

Abstract:

BACKGROUND: Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a relatively common disabling illness in adolescents that may limit participation in daily life.

AIM: This study explored interactions between the illness experiences of adolescents with CFS/ME, their occupational lives and expectations for the future.

METHODS: Seven adolescents with CFS/ME were interviewed. The interviews were analyzed using thematic analysis.

RESULTS: Three themes were developed. ‘Being ruled by an unfamiliar and inexplicable body’, which illustrated that altered and strange bodies seemed to separate and disrupt the participants from their former occupational lives. ‘On the sideline of life with peers’, which demonstrated that the informants spent time at home, doing undemanding activities instead of participating in activities with peers. ‘A coherent connection between present and future life’, which was reflected by how the participants eventually accepted their situation and rebuilt a meaningful occupational life and value of self.

CONCLUSION: CFS/ME made the body unfamiliar and disconnected informants from participating in their usual daily occupations. A coherent interaction between body, occupational life and social self was achieved by taking their new body into account and adjusting their occupations accordingly. This practice enabled the participants to hope for a better future life.

Investigating the effectiveness and cost-effectiveness of FITNET-NHS (Fatigue In Teenagers on the interNET in the NHS) compared to Activity Management to treat paediatric chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME): protocol for a randomised controlled trial

Abstract:

BACKGROUND: Paediatric chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) is a relatively common and disabling condition. The National Institute for Health and Clinical Excellence (NICE) recommends Cognitive Behavioural Therapy (CBT) as a treatment option for paediatric CFS/ME because there is good evidence that it is effective. Despite this, most young people in the UK are unable to access local specialist CBT for CFS/ME. A randomised controlled trial (RCT) showed FITNET was effective in the Netherlands but we do not know if it is effective in the National Health Service (NHS) or if it is cost-effective. This trial will investigate whether FITNET-NHS is clinically effective and cost-effective in the NHS.

METHODS: Seven hundred and thirty-four paediatric patients (aged 11-17 years) with CFS/ ME will be randomised (1:1) to receive either FITNET-NHS (online CBT) or Activity Management (delivered via video call). The internal pilot study will use integrated qualitative methods to examine the feasibility of recruitment and the acceptability of treatment. The full trial will assess whether FITNET-NHS is clinically effective and cost-effective. The primary outcome is disability at 6 months, measured using the SF-36-PFS (Physical Function Scale) questionnaire. Cost-effectiveness is measured via cost-utility analysis from an NHS perspective. Secondary subgroup analysis will investigate the effectiveness of FITNET-NHS in those with co-morbid mood disorders.

DISCUSSION: If FITNET-NHS is found to be feasible and acceptable (internal pilot) and effective and cost-effective (full trial), its provision by the NHS has the potential to deliver substantial health gains for the large number of young people suffering from CFS/ME but unable to access treatment because there is no local specialist service. This trial will provide further evidence evaluating the delivery of online CBT to young people with chronic conditions.

Chronic fatigue syndrome in Chinese middle-school students

Abstract:

The objective of the present study was to determine the prevalence of chronic fatigue syndrome (CFS) and its associated factors in middle-school students in Suzhou, China. From September 2010 to January 2011, across-sectional study was conducted in junior- and senior middle-school students aged 10 to 18 years using a battery of confidential questionnaires. Our results indicate that 18,139 completed the questionnaires effectively, of whom 163 (0.9%) met the definition of CFS, with senior high-school students and male students predominating. The prevalence of CFS in the middle-school students increased steadily with age. The main symptoms of CFS in these students included being afraid of going to school, despondency, and irritability in addition to those specified in the Centers for Disease Control and Prevention (CDC). Our study shows that CFS is prevalent among Chinese teenagers, and requiring proper intervention and treatment.
