Psychosocial functioning and health-related quality of life in paediatric inflammatory bowel disease

Gastrointestinal Disorders in Adolescents and Young Adults: Preparing for a Smooth Transition to Adult-Centered Care

Chronic gastrointestinal disorders are prevalent in youth worldwide. The chronicity of these conditions often results in their persistence into adulthood. Challenges typically faced by young people transitioning to adulthood are often exacerbated in those with chronic gastrointestinal disease. Increased awareness of these challenges among health care professionals and appropriate policies and procedures for health care transition are critical. This article summarizes research on the challenges faced by emerging adults with the gastrointestinal disease during the transition to adult care. Barriers to optimal transitional care and current guidelines are discussed and used to offer practical recommendations for health care professionals working with this population.

Illness stigma, body image dissatisfaction, thwarted belongingness and depressive symptoms in youth with inflammatory bowel disease

BACKGROUND

Elevated depressive symptoms are observed in a significant number of youth with inflammatory bowel disease (IBD) and have been linked to illness stigma and social isolation. Body image dissatisfaction is an understudied variable in the pediatric IBD literature that may be related to both stigma and social difficulties. It is suspected that, due to the stigmatizing nature of IBD, some youth may feel self-conscious about their body image, which contributes to decreased feelings of social belongingness and ultimately depressive symptoms. The current study tested an illness stigma→ body image dissatisfaction→ thwarted belongingness→ depressive symptoms serial mediation model, in which IBD stigma was hypothesized to indirectly influence youth depressive symptoms through the sequential effects of stigma on body image dissatisfaction and thwarted social belongingness.

METHODS

Youth with IBD (N = 75) between 10 and 18 years old were recruited from a pediatric gastroenterology clinic and completed psychosocial measures. Disease severity was assessed by a physician global assessment. Current medications and BMI data were collected.

RESULTS

Analyses revealed significant direct effects among the modeled variables and a significant serial indirect path for illness stigma→ body image dissatisfaction→ thwarted belongingness→ depressive symptoms, controlling for sex, BMI and prednisone medication.

CONCLUSIONS

Youth who perceive greater IBD stigma are more likely to experience increased body image dissatisfaction due to their IBD, which may engender feelings of social estrangement and ultimately elevated depressive symptoms. Depressive symptoms and the psychosocial challenges faced by youth should be routinely monitored as part of comprehensive IBD management.

Paediatric Inflammatory Bowel Disease and its Relationship with the Microbiome

Paediatric inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the digestive tract, comprising of Crohn's disease (CD), ulcerative colitis (UC), and, where classification is undetermined, inflammatory bowel disease unclassified (IBDU). Paediatric IBD incidence is increasing globally, with prevalence highest in the developed world. Though no specific causative agent has been identified for paediatric IBD, it is believed that a number of factors may contribute to the development of the disease, including genetics and the environment. Another potential component in the development of IBD is the microbiota in the digestive tract, particularly the gut. While the exact role that the microbiome plays in IBD is unclear, many studies acknowledge the complex relationship between the gut bacteria and pathogenesis of IBD. In this review, we look at the increasing number of studies investigating the role the microbiome and other biomes play in paediatric patients with IBD, particularly changes associated with IBD, varying disease states, and therapeutics. The paediatric IBD microbiome is significantly different to that of healthy children, with decreased diversity and differences in bacterial composition (such as a decrease in Firmicutes). Changes in the microbiome relating to various treatments of IBD and disease severity have also been observed in multiple studies. Changes in diversity and composition may also extend to other biomes in paediatric IBD, such as the virome and the mycobiome. Research into biome differences in IBD paediatric patients may help progress our understanding of the aetiology of the disease.

Determinants of quality of life and psychosocial adjustment to pediatric inflammatory bowel disease: A systematic review focused on Crohn's disease

BACKGROUND

Crohn's disease is a chronic and unpredictable inflammatory bowel disease that leads to important psychosocial difficulties especially during sensitive developmental stages such as childhood and adolescence. While risk factors for mood disorders have been identified in the literature, those for quality of life and psychosocial functioning have not.

OBJECTIVE

This systematic review explored the determinants of quality of life and psychosocial adjustment to pediatric Crohn's disease.

METHOD

Four international databases were consulted in March 2020: PubMed, PsychInfo, PubPsych and Cochrane Library. A series of keywords were entered in each database to identify the most recent relevant studies.

RESULTS

One hundred and sixty-eight articles were identified, of which twenty-nine met the inclusion criteria. The majority explored the determinants of quality of life, depression and anxiety, with a few focusing on psychosocial functioning. Consistently with the literature on psychological morbidity, disease activity and parental stress were also strong predictors of quality of life and psychosocial functioning. New evidence showed that abdominal pain, negative illness perceptions and internalizing symptoms were also common predictors of these outcomes.

CONCLUSIONS

Some risk factors of quality of life, distress and psychosocial functioning are similar, which could indicate that some patients could be at risk of presenting an accumulation of difficulties adjusting to the disease. The identification of these risk factors is fundamental to propose appropriate interventions. Therapeutic education, therapies focused on pain management or on the parent-child relationship can be considered to allow a better adjustment or prevent difficulties.

The Contributions of Illness Stigma, Health Communication Difficulties, and Thwarted Belongingness to Depressive Symptoms in Youth with Inflammatory Bowel Disease

OBJECTIVE

Youth with inflammatory bowel disease (IBD) often experience difficulties communicating about their disease. It is suspected that the stigmatizing nature of IBD symptoms contributes to youths' health communication difficulties, leaving youth feeling disconnected from their social environment and potentially resulting in decreased social belongingness and poorer emotional functioning. In this study, we tested an illness stigma → health communication difficulties → thwarted belongingness → depressive symptoms serial mediation model. It was anticipated that youth illness stigma would confer a serial indirect effect on youth depressive symptoms through the sequential effects of stigma on health communication difficulties and thwarted social belongingness.

METHODS

Seventy-five youth with IBD between the ages of 10 and 18 completed measures of perceived illness stigma, health communication difficulties, thwarted belongingness, and depressive symptoms.

RESULTS

Results indicated a significant illness stigma → thwarted belongingness → depressive symptoms simple mediation path. Importantly, findings also revealed a significant serial mediation path for illness stigma → health communication difficulties → thwarted belongingness → depressive symptoms.

CONCLUSIONS

Youth who perceive greater IBD stigma appear to experience increased difficulty communicating about their IBD with others, which in turn is associated with feelings of thwarted social belongingness and ultimately elevated depressive symptoms. These findings suggest that difficulty communicating about IBD is one potential route by which illness stigma has a negative impact on youth adjustment outcomes. Results could also inform clinical interventions to address IBD stigma and health communication difficulties associated with the social and emotional challenges in youth with IBD.

Psychological Outcomes of a Cognitive Behavioral Therapy for Youth with Inflammatory Bowel Disease: Results of the HAPPY-IBD Randomized Controlled Trial at 6- and 12-Month Follow-Up

Youth with inflammatory bowel disease (IBD) often experience psychological difficulties, such as anxiety and depression. This randomized controlled study tested whether a 3-month disease-specific cognitive behavioral therapy (CBT) in addition to standard medical care versus standard medical care only was effective in improving these youth's psychological outcomes. As this study was aimed at prevention, we included 70 youth (10-25 years) with IBD and symptoms of subclinical anxiety and/or depression, and measured psychological outcomes at 6- and 12-month follow-up. In general, participants in both groups showed improvements in anxiety, depression, health-related quality of life, social functioning, coping, and illness perceptions, sustained until 12 months follow-up. Overall, we found no differences between those receiving additional CBT and those receiving standard medical care only. We assume that this can be explained by the perceived low burden (both somatically and psychologically) or heightened awareness of psychological difficulties and IBD. ClinicalTrials.gov NCT02265588.

Body Image Dissatisfaction among Pediatric Patients with Inflammatory Bowel Disease

OBJECTIVES

To determine risk factors for body image dissatisfaction among pediatric patients with inflammatory bowel disease (IBD).

STUDY DESIGN

We performed a cross-sectional study of children aged 9-18 years in the IBD Partners Kids & Teens cohort. Participants completed surveys including demographics, disease characteristics and activity indices, and psychosocial outcomes measured by IMPACT-III questionnaires. We defined body image dissatisfaction if participants answered "I look awful" or "I look bad." Bivariate analyses assessed associations between body image dissatisfaction and demographic, disease-related and psychosocial factors; logistic regression models evaluated associations between risk factors and body image dissatisfaction.

RESULTS

IMPACT-III was completed by 664 patients, with 74 (11.1%) reporting body image dissatisfaction. Patients with body image dissatisfaction were more likely to be female (P < .01), older (median age 15 vs 13 years, P < .01), and diagnosed with IBD at an older age (12 vs 10 years, P < .01). Those with body image dissatisfaction had greater body mass index percentile (P = .02), more active disease (P < .01), more current steroid use (P < .01), and more depression and anxiety (P < .01). Female sex (OR 2.31; 95% CI 1.22-4.39), depression (OR 4.73; 95% CI 2.41-9.26), and anxiety (OR 5.42; 95% CI 2.48-11.80) were independently associated with body image dissatisfaction.

CONCLUSIONS

In this cohort, risk factors for body image dissatisfaction include female sex, older age at diagnosis, active disease, current steroid use, greater body mass index, and comorbid mood disorder. Interventions targeting modifiable risk factors for body image dissatisfaction may improve quality of life in pediatric patients with body image dissatisfaction.

Quality of Life in Children and Adolescents with Inflammatory Bowel Disease: Impact and Predictive Factors

PURPOSE

Inflammatory bowel disease (IBD) in children and adolescents is associated with high morbidity and possibly has a significant negative impact on their quality of life. This study aimed to evaluate the quality of life of children and adolescents with IBD and define the variables that impact these individuals.

METHODS

We administered the Pediatric Quality of Life Questionnaire (PedsQL) to 35 children and adolescents diagnosed with IBD and with available quantitative data from clinical records on epidemiology, clinical evolution, complementary tests, medical interventions, and disease activity. Data were evaluated according to the IBD type and compared with a control group of healthy children.

RESULTS

The study group showed a significantly lower PedsQL score than the control group (p<0.01). Significant factors contributing to poor overall quality of life included female sex, Crohn's disease, surgery, and food restrictions. Symptoms such as diarrhea and the fear of using public toilets were associated with low physical scores. Feeling sick had a negative impact on the emotional PedsQL scores. Patients with a fear of using public toilets, anthropometric scores below the 3rd percentile, and greater disease activity scored lower in the social domain. Regarding school and psychosocial evaluations, younger children with symptom onset after the age of 2 years had lower scores than younger children with symptom onset before the age of 2 years.

CONCLUSION

IBD negatively affects the quality of life of children and adolescents based on its impact on the physical, emotional, social, and psychosocial statuses of these patients.

Predicting the development of psychological morbidity in inflammatory bowel disease: a systematic review

BACKGROUND

Psychological morbidity in inflammatory bowel disease is common with significant impact on quality of life and health outcomes, but factors which predict the development of psychological morbidity are unclear.

AIM

To undertake a systematic literature review of the predictors of psychological morbidity in patients with inflammatory bowel disease.

METHODS

Electronic searches for English-language articles were performed with keywords relating to psychological morbidity according to the Diagnostic and Statistical Manual of Mental Disorders IV and subsequent criteria, and inflammatory bowel disease; in MEDLINE, PsychInfo, Web of Science and EMBASE for studies published from January 1997 to 25 January 2019.

RESULTS

Of 660 studies identified, seven met the inclusion criteria. All measured depression, with three also measuring anxiety. Follow-up duration was variable (median of 18 months range 6-96 months). Risk factors identified for development of psychological morbidity included physical factors: aggressive disease (HR 5.77, 95% CI 1.89 to 17.7) and greater comorbidity burden (OR 4.31, 95% CI 2.83 to 6.57) and psychological risk factors: degree of gratitude (r=-0.43, p<0.01) and parenting stress (R-change=0.03, F(1,58)=35.6, p<0.05). Age-specific risk was identified with young people (13-17 years) at increased risk.

CONCLUSIONS

Identifiable risks for the development of psychological morbidity in inflammatory bowel disease include physical and psychological factors. Further research is required from large prospective studies to enable early interventions in those at risk and reduce the impact of psychological morbidity.

Illness Perceptions and Depression Are Associated with Health-Related Quality of Life in Youth with Inflammatory Bowel Disease

BACKGROUND

In youth with inflammatory bowel disease (IBD), health-related quality of life (HRQOL) has been shown to be affected by individual disease factors and specific psychological factors. The innovative aim of this study is to examine the combined impact of psychological factors (illness perceptions, cognitive coping, anxiety, and depression) on HRQOL, over and above the associations of demographic and disease factors with HRQOL in youth with IBD.

METHOD

Data on clinical disease activity, illness perceptions, cognitive coping, anxiety, depression, and HRQOL were prospectively collected in 262 consecutive youth (age 10-20, 46.6% male) with confirmed IBD. Multiple linear regression analyses tested the associations of demographic, disease, and psychological variables with HRQOL in separate groups for Crohn's disease (CD; N = 147) and ulcerative colitis and IBD unclassified (UC/IBD-U; N = 115), using age-specific validated instruments.

RESULTS

In both disease groups, more negative illness perceptions (ß = - .412; ß = - .438, p < .001) and more depression (ß = - .454; ß = - .279, p < .001) were related to lower HRQOL. In the UC/IBD-U group, more anxiety was related to lower HRQOL (ß = - .201, p = .001). The model with the psychological variables explained a large and significant amount of variance in both groups: 74% and 83%, respectively (p < .001).

CONCLUSION

In 10-20-year-old IBD patients, negative illness perceptions and depression were significantly and more strongly associated with lower HRQOL than demographic and disease factors. Thus, it is important to integrate psychological factors in the treatment for IBD patients. To improve HRQOL in young IBD patients, psychological interventions should be targeted at negative illness perceptions and depression.

The incidence of cancer and mortality in paediatric onset inflammatory bowel disease in Denmark and Finland during a 23-year period: a population-based study

BACKGROUND

Recent studies report increased risks of both cancer and mortality in paediatric onset inflammatory bowel disease (pIBD) but the reproducibility of this is unknown.

AIM

To estimate the risk of cancer and mortality in the Danish and Finnish pIBD population in a 23-year period compared to the general population.

METHODS

The pIBD population was defined as individuals registered in the national patient registries with a diagnosis of Crohn's disease (CD), ulcerative colitis (UC) or IBD-unclassified before their 18th birthday from 1992 to 2014. This cohort was cross referenced with the national cancer and mortality registries identifying all pIBD patients who subsequently developed cancer and/ or died and followed up to the end of 2014. Risk estimates are presented as standardised incidence ratios calculated based on incidence figures from the populations.

RESULTS

Six thousand six hundred and eight-nine patients with pIBD were identified (median age at follow-up 22.3 years; median follow-up: 9.6 years [interquartile range: 4.8-16.0]). Seventy-two subsequently developed cancer and 65 died. The standardised incidence ratio of cancer in general was 2.6 (95% CI: 1.8-3.7) and 2.5 (95% CI: 1.8-3.4) in CD and UC, respectively. The standardised mortality ratios were 2.2 (95% CI: 1.4-3.4) and 3.7 (95% CI: 2.7-5.0) in CD and UC, respectively. The leading causes for mortality were cancer, suicide and infections.

CONCLUSIONS

We found an increased risk of cancer and mortality in pIBD. This underlines the importance of cancer surveillance programs and assessment of mental health in the standard of care in adolescent pIBD patients.

European Crohn's and Colitis Organisation Topical Review on Complementary Medicine and Psychotherapy in Inflammatory Bowel Disease

Patients with inflammatory bowel disease [IBD] increasingly use alternative and complementary therapies, for which appropriate evidence is often lacking. It is estimated that up to half of all patients with IBD use various forms of complementary and alternative medicine during some point in their disease course. Considering the frequent use of such therapies, it is crucial that physicians and patients are informed about their efficacy and safety in order to provide guidance and evidence-based advice. Additionally, increasing evidence suggests that some psychotherapies and mind-body interventions may be beneficial in the management of IBD, but their best use remains a matter of research. Herein, we provide a comprehensive review of some of the most commonly used complementary, alternative and psychotherapy interventions in IBD.

Fatigue in children and adolescents with inflammatory bowel disease

AIM

To identify factors other than active disease and anemia that contribute to fatigue in pediatric inflammatory bowel disease (IBD).

METHODS

We performed an electronic search in Medline and EMBASE from their inception to May 2017 using the search term "fatigue" or the related keywords "physical impairment" and "inflammatory bowel disease" with the filter "child" (age 0-18 years). Cross-sectional and case-control studies were included. We restricted our search to studies published in English. We used the PRISMA checklist and flow diagram. Duplicate articles were manually deleted in End Note. To identify further relevant studies, we checked the reference lists of the selected articles.

RESULTS

We identified 149 papers, of which 19 were retrieved for full text review. Eleven studies were subsequently excluded because fatigue was not evaluated as an outcome measure. Eight papers focused on the desired topic and were discussed in the final analysis. A lack of uniformity of outcome measures made the pooling of data impossible. In all but one study, questionnaires were used to evaluate fatigue. In the remaining study, an accelerometer was used to measure daily activities, sleeping time and their relationships with fatigue in a more quantifiable manner. Adolescents with IBD are significantly more fatigued than healthy controls. In addition to active disease, increased anxiety or depression and disturbed family relationships were frequently reported predictors of fatigue. Quantitative measurement of physical activity in patients with Crohn's disease showed a reduction in the number of steps per day, and patients with ulcerative colitis had a shorter duration of physical activity during the day.

CONCLUSION

Fatigue in pediatric IBD is related to a combination of biological, functional and behavioral factors, which should all be taken into account when managing fatigue.

Swedish Children's Lived Experience of Ulcerative Colitis

Inflammatory bowel disease (IBD) is increasing in children. When this lifelong illness is diagnosed in childhood, especially during adolescence, it may have a negative impact on children's quality of life. The aim of the present study was to illuminate the meaning of children's lived experience of ulcerative colitis. Seven children aged between 10 and 18 years were recruited from University Hospital South Sweden and interviewed about the phenomenon under scrutiny. Data were analyzed by means of a phenomenological hermeneutical method. The meaning of the children's lived experience of ulcerative colitis was summed up as a main theme. A daily struggle to adapt and be perceived as normal consisted of 4 subthemes: being healthy despite the symptoms, being healthy despite being afraid, being healthy despite a sense of being different, and being healthy despite needing support. The children strove to perceive themselves as healthy, and they needed to be perceived as healthy, especially when experiencing symptoms of inflammatory bowel disease. Children with inflammatory bowel disease confront various problems, such as ambitions and goals that are hard to achieve, due to reduced abilities as a result of the illness or an insufficiently adapted environment.

Systematic review with meta-analysis: anxiety and depression in children and adolescents with inflammatory bowel disease

BACKGROUND

The co-existence of psychological problems and paediatric inflammatory bowel disease (IBD) is receiving increasing attention. Most studies investigated anxiety and depression, with prevalence rates varying from 0% to 50%. A systematic review is necessary to provide clear insight into the prevalence of anxiety and depression in paediatric IBD.

AIM

To systematically evaluate available data on the prevalence of anxiety and depressive symptoms and disorders in paediatric IBD (aged 6-18 years).

METHODS

Comprehensive searches were performed in Embase, Medline Ovid, Web of Science, Cochrane, PubMed, PsychInfo Ovid, and Google scholar for studies published from 1994 to 2017. Pooled prevalence rates were calculated using inverse variance heterogeneity models. Meta-regression was used to study if disease type, disease activity and gender influence prevalence.

RESULTS

Twenty-eight studies (N = 8107, mean age: 14.3) were identified. Pooled prevalence estimates were 16.4% (95% confidence interval [CI] 6.8%-27.3%) for anxiety symptoms and 4.2% (95% CI 3.6%-4.8%) for anxiety disorders. Pooled prevalence estimates were 15.0% (95% CI 6.4%-24.8%) for depressive symptoms and 3.4% (95% CI 0%-9.3%) for depressive disorders. Meta-regression showed no influence of disease type or gender on these prevalence rates, but studies with a higher percentage of active disease had a higher rate of depressive symptoms.

CONCLUSIONS

The described pooled prevalence of anxiety and depressive symptoms is lower than in adult IBD. However, due to varying instruments/cut-offs for measuring symptoms and few studies investigating disorders, the results should be interpreted with caution. Cross-cultural use of the same instruments is needed to gain better insight into prevalence rates.

Management of Paediatric Ulcerative Colitis, Part 1: Ambulatory Care-An Evidence-based Guideline From European Crohn's and Colitis Organization and European Society of Paediatric Gastroenterology, Hepatology and Nutrition

BACKGROUND

The contemporary management of ambulatory ulcerative colitis (UC) continues to be challenging with ∼20% of children needing a colectomy within childhood years. We thus aimed to standardize daily treatment of pediatric UC and inflammatory bowel diseases (IBD)-unclassified through detailed recommendations and practice points.

METHODS

These guidelines are a joint effort of the European Crohn's and Colitis Organization (ECCO) and the Paediatric IBD Porto group of European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). An extensive literature search with subsequent evidence appraisal using robust methodology was performed before 2 face-to-face meetings. All 40 included recommendations and 86 practice points were endorsed by 43 experts in Paediatric IBD with at least an 88% consensus rate.

RESULTS

These guidelines discuss how to optimize the use of mesalamine (including topical), systemic and locally active steroids, thiopurines and, for more severe disease, biologics. The use of other emerging therapies and the role of surgery are also covered. Algorithms are provided to aid therapeutic decision-making based on clinical assessment and the Paediatric UC Activity Index (PUCAI). Advice on contemporary therapeutic targets incorporating the use of calprotectin and the role of therapeutic drug monitoring are presented, as well as other management considerations around pouchitis, extraintestinal manifestations, nutrition, growth, psychology, and transition. A brief section on disease classification using the PIBD-classes criteria and IBD-unclassified is also part of these guidelines.

CONCLUSIONS

These guidelines provide a guide to clinicians managing children with UC and IBD-unclassified management to provide modern management strategies while maintaining vigilance around appropriate outcomes and safety issues.

IMPACT-III is a valid and reliable questionnaire for assessing health-related quality of life in Swedish children with inflammatory bowel disease

AIM

This study examined the reliability, validity and factor structure of the Swedish version of the IMPACT-III questionnaire for assessing health-related quality of life in children with inflammatory bowel disease.

METHODS

We recruited 202 participants aged eight to 18 years, who were enrolled from 16 of the 23 paediatric gastroenterology clinics across Sweden during 2010-2013. This cross-sectional study compared two versions of the IMPACT-III questionnaire - one with six factors and 35 items and one with four factors and 19 items - plus the Paediatric Quality of Life Inventory 4.0 Generic Core Scale. Disease activity was assessed and defined as active or inactive.

RESULTS

The mean total score for the six-factor IMPACT-III scale was 143.7/175, with a standard deviation (SD) of 17.9. There was a significant difference in mean total scores between the 133 children with inactive disease (147.8, SD: 14.9) and the 52 with active disease (133.0, SD: 20.3). Confirmatory factor analysis showed that the four-factor scale was more robust than the original six-factor scale. Concurrent validity and discriminant validity were high for both versions.

CONCLUSION

The Swedish version of the IMPACT-III questionnaire was valid and reliable, but the shorter, four-factor version is quicker and may be more convenient in clinical settings.

Psychological wellbeing and physical activity in children and adolescents with inflammatory bowel disease compared to healthy controls

BACKGROUND

Children and adolescents with inflammatory bowel disease (IBD) report impairments in daily activities, social interactions and coping. Findings regarding psychological functioning are inconsistent, while limited information is available on objectively assessed physical activity (PA). The aims of the present study were therefore to compare anthropometric dimensions, blood values, psychological functioning and PA of children and adolescents with IBD with healthy controls.

METHODS

Forty-seven children and adolescents took part in the study. Of these, 23 were diagnosed with IBD (mean age: 13.88 years, 44% females). The IBD group was divided into a medically well adjusted "remission-group" (n = 14; IBD-RE) and a group with an "active state" of disease (n = 8; IBD-AD). Healthy controls (n = 24; HC) were age- and gender-matched. Participants' anthropometric data, blood values and objective PA were assessed. Further, participants completed questionnaires covering socio-demographic data and psychological functioning.

RESULTS

Participants with IBD-AD showed higher erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) values, haemoglobin, and leukocyte values. IBD-AD had poorer psychological functioning and lower PA (average steps per day) compared to IBD-RE and HC. No mean differences were found between IBD-RE and HC.

CONCLUSIONS

The pattern of results suggests that effective medical treatment of IBD in children and adolescents is associated with favorable physiological parameters, psychological dimensions and PA. Psychological counselling of children and adolescents in an active state of IBD seem to be advised in addition to standard treatment schedules.

Long-term outcomes of pediatric inflammatory bowel disease

The incidence and prevalence of childhood-onset inflammatory bowel diseases (IBD), including subtypes Crohn's disease and ulcerative colitis, have risen dramatically in recent years, and have emerged globally as important pediatric chronic diseases. Therefore, health care providers are more frequently encountering very young children with IBD, a chronic and incurable condition requiring life-long therapy. These children are living long lives with IBD and therefore knowledge of long-term outcomes is increasingly important to better counsel families and determine the best course of treatment. This review summarizes the current knowledge and literature surrounding long-term outcomes of pediatric IBD, with emphasis on the following areas: need for surgery due to complicated disease behavior, risk of disease remission and recurrence, mental health and psychosocial well-being, educational outcomes, linear growth impairment, cancer risk, and mortality. In addition, we review recent research about predicting negative long-term outcomes in children with IBD.

Education, Employment, Income, and Marital Status Among Adults Diagnosed With Inflammatory Bowel Diseases During Childhood or Adolescence

BACKGROUND & AIMS

We aimed to assess levels of education attained, employment, and marital status of adults diagnosed with inflammatory bowel diseases (IBD) during childhood or adolescence, compared with healthy individuals in Canada.

METHODS

We performed a cross-sectional study of adults diagnosed with IBD in childhood or adolescence at Children's Hospital in Winnipeg, Manitoba from January 1978 through December 2007. Participants (n = 112) answered a semi-structured questionnaire on educational achievements, employment, and marital status. Patients were matched for age and sex with random healthy individuals from the 2012 Canadian Community Health Survey (controls, 5 per patient). Conditional binary logistic regression and random-effects ordinal logistic regression models were used for analysis.

RESULTS

Patients were followed for a mean duration of 14.3 years (range, 3.1-34.5 years). Persons with IBD were more likely to earn more money per annum and attain a post-secondary school degree or receive a diploma than controls (odds ratio, 1.72; 95% confidence interval, 1.13-2.60; P < .01 and odds ratio, 2.73; 95% confidence interval, 1.48-5.04; P < .01, respectively). There was no significant difference between patients and controls in employment or marital status.

CONCLUSIONS

Adults diagnosed with IBD during childhood seem to achieve higher education levels than individuals without IBD. This observation should provide reassurance to children with IBD and their parents. ClinicalTrials.gov number: NCT02152241.

Systematic review: psychological morbidity in young people with inflammatory bowel disease - risk factors and impacts

BACKGROUND

Psychological morbidity in young people aged 10-24 years, with inflammatory bowel disease (IBD) is increased, but risk factors for and impacts of this are unclear.

AIM

To undertake a systematic literature review of the risk factors for and impact of psychological morbidity in young people with IBD.

METHODS

Electronic searches for English-language articles were performed with keywords relating to psychological morbidity according to DSM-IV and subsequent criteria; young people; and IBD in the MEDLINE, PsychInfo, Web of Science and CINAHL databases for studies published from 1994 to September 2014.

RESULTS

One thousand four hundred and forty-four studies were identified, of which 30 met the inclusion criteria. The majority measured depression and anxiety symptoms, with a small proportion examining externalising behaviours. Identifiable risk factors for psychological morbidity included: increased disease severity (r(2) = 0.152, P < 0.001), lower socioeconomic status (r(2) = 0.046, P < 0.001), corticosteroids (P ≤ 0.001), parental stress (r = 0.35, P < 0.001) and older age at diagnosis (r = 0.28, P = 0.0006). Impacts of psychological morbidity in young people with IBD were wide-ranging and included abdominal pain (r = 0.33; P < 0.001), sleep dysfunction (P < 0.05), psychotropic drug use (HR 4.16, 95% CI 2.76-6.27), non-adherence to medication (12.6% reduction) and negative illness perceptions (r = -0.43).

CONCLUSIONS

Psychological morbidity affects young people with IBD in a range of ways, highlighting the need for psychological interventions to improve outcomes. Identified risk factors provide an opportunity to develop targeted therapies for a vulnerable group. Further research is required to examine groups under-represented in this review, such as those with severe IBD and those from ethnic minorities.

Effectiveness of disease-specific cognitive-behavioural therapy on depression, anxiety, quality of life and the clinical course of disease in adolescents with inflammatory bowel disease: study protocol of a multicentre randomised controlled trial (HAPPY-IBD)

Introduction

Adolescents with inflammatory bowel disease (IBD) show a higher prevalence of depression and anxiety, compared to youth with other chronic diseases. The inflammation-depression hypothesis might explain this association, and implies that treating depression can decrease intestinal inflammation and improve disease course. The present multicentre randomised controlled trial aims to test the effectiveness of an IBD-specific cognitive–behavioural therapy (CBT) protocol in reducing symptoms of subclinical depression and anxiety, while improving quality of life and disease course in adolescents with IBD.

Methods and analysis

Adolescents with IBD (10–20 years) from 7 hospitals undergo screening (online questionnaires) for symptoms of depression and anxiety. Those with elevated scores of depression (Child Depression Inventory (CDI) ≥13 or Beck Depression Inventory (BDI) II ≥14) and/or anxiety (Screen for Child Anxiety Related Disorders: boys ≥26, girls ≥30) receive a psychiatric interview. Patients meeting criteria for depressive/anxiety disorders are referred for psychotherapy outside the trial. Patients with elevated (subclinical) symptoms are randomly assigned to medical care-as-usual (CAU; n=50) or CAU plus IBD-specific CBT (n=50). Main outcomes: (1) reduction in depressive and/or anxiety symptoms after 3 months and (2) sustained remission for 12 months. Secondary outcomes: quality of life, psychosocial functioning, treatment adherence. In addition, we will assess inflammatory cytokines in peripheral blood mononuclear cells and whole blood RNA expression profiles. For analysis, multilevel linear models and generalised estimating equations will be used.

Ethics and dissemination

The Medical Ethics Committee of the Erasmus MC approved this study. If we prove that this CBT improves emotional well-being as well as disease course, implementation is recommended.

Trial registration number

NCT02265588.

Adherence to Oral Maintenance Treatment in Adolescents With Inflammatory Bowel Disease

OBJECTIVES

The aim of this study was to systematically review the rates of nonadherence to oral maintenance treatment in adolescents with inflammatory bowel disease (IBD), and to describe perceived barriers to adherence and psychosocial factors involved.

METHODS

The article considered studies published in MEDLINE, Embase, and PsycINFO up to March 2015. Studies that had collected data on adherence to thiopurines or aminosalicylates in a cohort of adolescents with IBD. Case reports and case series were excluded.

RESULTS

A total of 25 studies were included. Lack of uniformity of outcome measures made pooling of data impossible. Rates of medication nonadherence ranged from 2% to 93%. The most frequently reported barriers were "just forgot," "wasn't home," and "interferes with activity." Family dysfunction, peer victimization, poor health-related quality of life, poor child-coping strategies, anxiety, and depressive symptoms were associated with medication nonadherence.

CONCLUSIONS

Nonadherence to oral maintenance therapy in adolescents with IBD is a significant health care problem and can lead to unnecessary escalation in therapy. Difficulties in family and social interactions, and psychosocial dysfunction can jeopardize IBD treatment outcome and should receive attention early in the course of the disease.

Psychological status in Iranian patients with ulcerative colitis and its relation to disease activity and quality of life

BACKGROUND

Psychological profile of inflammatory bowel disease patients is not well studied in Iran. We investigated the psychological status of Iranian patients with ulcerative colitis (UC) and its relationship with disease activity and quality of life (QOL).

MATERIALS AND METHODS

A cross-sectional study was conducted on adult UC patients. The Lichtiger Colitis Activity Index, Hospital Anxiety and Depression Scale, General Health Questionnaire-12, and WHOQOL-BREF, were completed by the patients.

RESULTS

From 120 studied patients, 35 (29.2%), 48 (40.0%), and 46 (38.3%) had significant anxiety, depression, and psychological distress, respectively. Anxiety, depression, and psychological distress were strongly correlated with disease activity (r = 0.357 to 0.439, P < 0.01). Disease activity was negatively correlated with all QOL dimensions (r = -0.245 to -0.550, P < 0.01). Anxiety, depression, and psychological distress were also negatively correlated with all QOL domains (r = -0.356 to -0.789, P < 0.01). In the regression models, anxiety was independently associated with active disease (β = 4.150, P = 0.049). Furthermore, disease activity was associated with the physical health (β = -0.371, P < 0.001). For almost all of the QOL domains, depression and psychological distress were independent predictors (β = -0.296 to -0.453, P < 0.001).

CONCLUSION

Anxiety, depression, and psychological distress are highly frequent in UC patients of our society and are strongly associated with disease activity. Depression and psychological distress are important predictors of poor QOL in these patients. Further prospective studies, as well as clinical trials, are warranted in this regard.

Development of a self-efficacy scale for adolescents and young adults with inflammatory bowel disease

BACKGROUND

Pediatric inflammatory bowel disease (IBD) self-management fits well within a social-cognitive framework. At the heart of social-cognitive theory is self-efficacy, a set of beliefs about one's ability to perform certain tasks. Self-efficacy is a strong predictor of health outcomes in chronic diseases and could serve as an intermediary outcome measure of self-management for pediatric IBD. The aim of this preliminary study was to develop items for the design of a self-efficacy scale specifically for adolescents and young adults with IBD.

METHODS

Survey development is an iterative process. As defined by the US Food and Drug Administration guidelines for developing a patient-reported outcome measurement, the first step of this process is to obtain patient input. Using qualitative research methods, adolescents and young adults were recruited from an outpatient pediatric gastroenterology clinic to participate in a semistructured interview. Transcriptions of the recorded interviews were reviewed for themes related to self-efficacy around disease management. A consensus panel of gastroenterologists and health psychologists reviewed the initially constructed items. Those specific items were then reviewed and adjusted by a panel of participants for content and understandability using cognitive interview methods. The resulting 13-item scale is presented here.

RESULTS

Nineteen patients and 5 parents participated in the study. The study sample was 42% girls, 79% whites, 74% had Crohn disease, and 79% had not required surgery. Median age was 15 years (range 10-22 years). Theme analysis and expert review yielded 13 items across 4 theoretical domains: managing medical care, managing daily life with IBD, managing emotions, and managing the future with IBD.

CONCLUSIONS

A 13-item disease-specific scale has been developed based on patient input to assess self-efficacy around self-management in adolescents with IBD. Efforts to validate this newly designed scale are presently under way.

Correlation of health-related quality of life in children with inflammatory bowel disease, their parents, and physician as measured by a visual analog scale

BACKGROUND AND AIMS

Inflammatory bowel disease has been shown to affect children's health-related quality of life (HRQOL) through the use of lengthy questionnaires. We examined whether a pediatric patient's HRQOL, measured by a rapid visual analog scale ("feeling thermometer"), correlates with the perceptions of the HRQOL as determined by the patient's pediatric gastroenterologist and parent(s). Additionally, we attempted to determine whether the HRQOL correlates with the patient's disease activity as determined by validated activity indices.

METHODS

A cross-sectional study of pediatric patients (ages 7-21 years) who were diagnosed as having Crohn disease, ulcerative colitis, or indeterminate colitis was conducted from January 2011 to May 2011. Each participant (patient, parent(s), and treating pediatric gastroenterologist) completed feeling thermometers to determine the symptom burden as well as therapeutic burden of the patient. The parent(s) and doctor were blinded to the patient's results. Pediatric Ulcerative Colitis Activity Index or a Short Pediatric Crohn Disease Activity Index (S-PCDAI) was calculated. Correlations between the participant's perceived burdens as well as their calculated disease activity were determined.

RESULTS

Sixty-seven children and their families participated, resulting in 101 visits. Patients had a mean age of 15.0 years, and there were 38 boys. There was a strong significant correlation between the patient's perceived symptom burden and that of the parent's (ρ 0.59, P < 0.001) and physician (ρ 0.48, P < 0.001). Similarly, there was a strong significant correlation between patient's perceived treatment burden and that of the parent treatment burden (ρ 0.49, P < 0.001) and, to a lesser degree, the physician (ρ 0.29, P < 0.003). The correlation coefficient was strongest between the physician's perception of the patient's symptom burden against the standard disease activity indices Pediatric Ulcerative Colitis Activity Index (ρ 0.69, P < 0.001) and Short Pediatric Crohn Disease Activity Index (ρ 0.65, P < 0.001).

CONCLUSIONS

The patient's HRQOL was highly correlated to both the physician's and parent's perceptions as well as their disease activity. The feeling thermometer is a quick, easy-to-use, visual analog scale that can be implemented in everyday practice to measure a pediatric patient's HRQOL.

Psychosocial dysfunction in children and adolescents with eosinophilic esophagitis

OBJECTIVE

Children with eosinophilic esophagitis (EoE) experience daily challenges related to coping with symptoms and the psychosocial effect of this chronic disease. The aim of this study was to identify features of psychosocial dysfunction experienced by children with EoE who were evaluated in a tertiary care program.

METHODS

We performed a retrospective review of EoE patients and their families' psychosocial evaluations performed in a tertiary care EoE program. Consecutive evaluations were analyzed to document reports of patients' disease-related pain/discomfort; feeding/appetite symptoms; sleep, social, and school problems; depression, anxiety; and overall psychological adjustment.

RESULTS

Sixty-four patients received psychosocial evaluation during an 18-month period and were analyzed. Sixty-nine percent of children evaluated experienced some form of psychosocial problems, including social difficulties (64%), anxiety (41%), sleep difficulties (33%), depression (28%), and school problems (26%). Adjustment problems were identified in 44% of the sample. Older children experienced more adjustment difficulties than younger children (P = 0.05). Sleep disturbances and feeding problems predominated in the younger children. Anxious behavior and depressive feelings increased with age. Children with gastrostomy tubes (G-tubes) had more social, school, and psychological adjustment problems than those without.

CONCLUSIONS

The majority of children with EoE who underwent health and behavior evaluation in a tertiary care program experienced psychosocial adjustment and coping problems. Evaluation and management by mental health professionals would likely benefit a majority of patients with this chronic disease.

Inflammatory bowel disease: an expanding global health problem

This review provides a summary of the global epidemiology of inflammatory bowel diseases (IBD). It is now clear that IBD is increasing worldwide and has become a global emergence disease. IBD, which includes Crohn’s disease (CD) and ulcerative colitis (UC), has been considered a problem in industrial-urbanized societies and attributed largely to a Westernized lifestyle and other associated environmental factors. Its incidence and prevalence in developing countries is steadily rising and has been attributed to the rapid modernization and Westernization of the population. There is a need to reconcile the most appropriate treatment for these patient populations from the perspectives of both disease presentation and cost. In the West, biological agents are the fastest-growing segment of the prescription drug market. These agents cost thousands of dollars per patient per year. The healthcare systems, and certainly the patients, in developing countries will struggle to afford such expensive treatments. The need for biological therapy will inevitably increase dramatically, and the pharmaceutical industry, healthcare providers, patient advocate groups, governments and non-governmental organizations should come to a consensus on how to handle this problem. The evidence that IBD is now affecting a much younger population presents an additional concern. Meta-analyses conducted in patients acquiring IBD at a young age also reveals a trend for their increased risk of developing colorectal cancer (CRC), since the cumulative incidence rates of CRC in IBD-patients diagnosed in childhood are higher than those observed in adults. In addition, IBD-associated CRC has a worse prognosis than sporadic CRC, even when the stage at diagnosis is taken into account. This is consistent with additional evidence that IBD negatively impacts CRC survival. A continuing increase in IBD incidence worldwide associated with childhood-onset of IBD coupled with the diseases’ longevity and an increase in oncologic transformation suggest a rising disease burden, morbidity, and healthcare costs. IBD and its associated neoplastic transformation appear inevitable, which may significantly impact pediatric gastroenterology and adult CRC care. Due to an infrastructure gap in terms of access to care between developed vs. developing nations and the uneven representation of IBD across socioeconomic strata, a plan is needed in the developing world regarding how to address this emerging problem.

Psychosocial developmental trajectory of adolescents with inflammatory bowel disease

BACKGROUND AND OBJECTIVES

Inflammatory bowel disease (IBD) is a chronic, debilitating disorder occurring in young patients in the most productive period of their lives. Little is known about the effect on the developmental trajectory of adolescents growing up with IBD. The purpose of this study was to assess the psychosocial developmental trajectory ("course of life") and sociodemographic outcomes in adolescents with IBD compared with peers from the general population.

METHODS

A total of 62 adolescents (response rate 74%, boys 51.6%, mean age 18.6 years) completed the course of life questionnaire.

RESULTS

Patients with IBD achieved fewer milestones on the domains of autonomy and social and psychosexual development compared with their healthy peers. They went less frequently on holidays without adults, had fewer jobs during secondary school, were less frequently going out to a bar/disco during secondary school, and were older when falling in love for the first time. After secondary school, patients with IBD were more often unemployed.

CONCLUSIONS

Negative consequences in terms of psychosocial development are prevalent in adolescents with IBD. Physicians should be attentive to these consequences and provide additional support if necessary. During transition to adult clinic, these topics are of major importance and should be an integral component of the comprehensive care of chronically ill adolescents and young adults.

Risk of inflammatory bowel disease according to self-rated health, pregnancy course, and pregnancy complications: a study within the Danish National Birth Cohort

BACKGROUND

Poor self-rated health (SRH) has been connected to immunological changes, and pregnancy complications have been suggested in the etiology of autoimmune diseases including inflammatory bowel disease (IBD). We evaluated the impact of self-rated pre-pregnancy health and pregnancy course, hyperemesis, gestational hypertension, and preeclampsia on risk of IBD.

METHODS

Information was collected by questionnaires from The Danish National Birth Cohort (enrolment 1996-2002) at 16(th) and 30(th) week of pregnancy and 6 months postpartum. A total of 55,699 women were followed from childbirth until development of IBD (using validated National Hospital Discharge Register diagnoses), emigration, death, or end of follow-up, 31(st) of October, 2011. Hazard ratios (HR) with 95% confidence intervals (CI) were calculated using Cox proportional hazards models adjusting for age and evaluating pre-pregnancy BMI, parity, alcohol and tobacco consumption, and socio-occupational status as potential confounders.

RESULTS

Risk of IBD increased with decreasing level of self-rated pre-pregnancy health (p = 0.002) and was elevated in women with poor self-rated pregnancy course (HR, 1.61, 95% CI 1.22-2.12). Associations persisted for more than 5 years postpartum. Hyperemesis and preeclampsia were not significantly associated with risk of IBD.

CONCLUSIONS

This is the first prospective observational study to suggest that poor self-rated health--in general and in relation to pregnancy--is associated with increased risk of IBD even in the long term though results needs further confirmation. Symptoms of specific pregnancy complications were, on the other hand, not significantly associated with risk of IBD.

Health-related quality of life in patients with inflammatory bowel disease: a single-center experience

BACKGROUND

Inflammatory bowel disease (IBD) has a negative impact on health-related quality of life (HRQoL). The aim of the study was to assess HRQoL of IBD patients in South-Western Greece.

METHODS

89 IBD patients [38 (42.7%) Crohn's disease (CD), 51 (57.3%) ulcerative colitis (UC)] were included. HRQoL was assessed using IBD questionnaire (IBDQ), which tests four health domains: bowel symptoms (BS), systemic symptoms (SS), emotional function (EF) and social function (SF). Total score (TS) ranges from 32 to 224. Disease activity was measured using Crohn's Disease Activity Index (CDAI) (CD), and Truelove and Witts classification (UC). The impact of epidemiological and disease-specific characteristics on IBDQ was studied.

RESULTS

No statistically significant difference was found in all IBDQ scores between UC and CD patients. No correlation was found regarding age, sex, smoking, anemia, disease duration and use of corticosteroids, 5-aminosalicylates or immunosuppressives with HRQoL. The factors found to have a major negative impact on all IBDQ scores was disease severity both in CD and UC, and education on bowel symptoms in CD. On multivariate analysis, only high disease activity had significant effects on total and dimensional scores of IBDQ in UC (TS, P=0.005; BS, P<0.001; SS, P=0.004; EF, P=0.05; SF, P=0.001), whereas in CD, only CDAI (TS, P=0.001; BS, P=0.004; SS, P=0.001; EF, P=0.003; SF, P=0.003) and education (TS, P=0.047; BS, P=0.004; SS, P=0.03) had significant effects.

CONCLUSIONS

IBD patients in remission experience better HRQoL than patients with active disease. Induction of remission should become the mainstay of care regarding improvement in HRQoL.

Psychosoziale Beratung

Die Verbesserung der medizinischen Versorgung in den vergangenen Jahrzehnten hat auch in der Kinder- und Jugendmedizin zu einer Erweiterung des Aufgabenfeldes geführt. Neben der organmedizinisch orientierten Behandlung hat die psychosoziale Beratung zunehmend an Bedeutung gewonnen. Hierfür scheinen zwei Entwicklungen relevant zu sein: – Die verbesserte Behandlung schwerer Erkrankungen wie z. B. der zystischen Fibrose oder chronischer Hepatopathien führt zu einer Verlängerung der Lebenserwartung der Patienten, wodurch verschiedene psychosoziale Aspekte der Erkrankung wie Berufswahl oder Partnerschaft erst relevant werden. – In den vergangenen Jahren hat sich die Struktur der Arzt- Patienten-Beziehung verändert: Der Patient bzw. die Eltern der behandelten Kinder ist bzw. sind nicht mehr nur passive(r) Empfänger ärztlicher Verordnungen, sondern Partner in einer Beziehung, in der der Arzt beratende und aufklärende Funktion hat. In dieser Beziehung wird vom betreuenden Arzt nicht nur erwartet, dass er über die Erkrankung, ihre Behandlung und über mögliche Nebenwirkungen seiner Behandlungsmethoden aufklärt, sondern auch über psychosoziale Folgen und Rahmenbedingungen sowie die Prognose informiert.

The organisation and structure of inflammatory bowel disease services for children and young people in the UK in 2010: significant progress but still room for improvement

BACKGROUND

Inflammatory bowel disease (IBD) is becoming more common in children. While treatment options remain limited the appropriate organisation and delivery of services are an integral part of good care.

METHODS

All eligible UK paediatric sites were invited to submit data for organisation of paediatric IBD services as of 1 September 2010. Comparison, when relevant, was made with the previous paediatric audit (2008) and the concurrently running adult audit.

RESULTS

24/25 (96%) of sites submitted data. The median number of patients managed and the median number of new IBD (ulcerative colitis and Crohn's disease only) cases per annum was 178 (IQR 136-281) and 32 (IQR 23-50), respectively. There was an increase in the IBD workforce including whole-time equivalent (WTE) IBD nurses (1.0 vs 1.5 WTE nurses, p=0.02). 1023 patients 16 years and younger were looked after in the 202 adult sites who submitted data; only 78/202 sites indicated they cared for 16-year-old and younger children; approximately half of these 78 sites had age-appropriate support facilities. Most paediatric sites have access to urgent endoscopy (83%), telephone advice (100%) and urgent clinic appointments (91%). Most sites did not have: shared care pathways with primary care (74%), annual reviews (71%), real time patient management systems (83%) and research network trial participation (78%).

CONCLUSIONS

Many aspects of paediatric IBD care in the UK are good and have shown significant improvement over recent years. There are areas in need of further change and specific regional and national action plans should address identified deficiencies before any future audit of paediatric and adult IBD services.

Management of pediatric ulcerative colitis: joint ECCO and ESPGHAN evidence-based consensus guidelines

BACKGROUND AND AIMS

Pediatric ulcerative colitis (UC) shares many features with adult-onset disease but there are some unique considerations; therefore, therapeutic approaches have to be adapted to these particular needs. We aimed to formulate guidelines for managing UC in children based on a systematic review (SR) of the literature and a robust consensus process. The present article is a product of a joint effort of the European Crohn's and Colitis Organization (ECCO) and the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN).

METHODS

A group of 27 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to ESPGHAN and ECCO members. A list of 23 predefined questions were addressed by working subgroups based on a SR of the literature.

RESULTS

A total of 40 formal recommendations and 68 practice points were endorsed with a consensus rate of at least 89% regarding initial evaluation, how to monitor disease activity, the role of endoscopic evaluation, medical and surgical therapy, timing and choice of each medication, the role of combined therapy, and when to stop medications. A management flowchart, based on the Pediatric Ulcerative Colitis Activity Index (PUCAI), is presented.

CONCLUSIONS

These guidelines provide clinically useful points to guide the management of UC in children. Taken together, the recommendations offer a standardized protocol that allows effective, timely management and monitoring of the disease course, while acknowledging that each patient is unique.
