Psychological Comorbidities in Childhood Celiac Disease: A Systematic Review

Long-term physical health conditions and youth anxiety and depression: Is there a causal link?

BACKGROUND

The prevalence of youth anxiety and depression has increased globally, with limited causal explanations. Long-term physical health conditions (LTCs) affect 20-40% of youth, with rates also rising. LTCs are associated with higher rates of youth depression and anxiety; however, it is uncertain whether observed associations are causal or explained by unmeasured confounding or reverse causation.

METHODS

Using data from the Norwegian Mother, Father, and Child Cohort Study (MoBa) and Norwegian National Patient Registry, we investigated phenotypic associations between childhood LTCs, and depression and anxiety diagnoses in youth (<19 years), defined using ICD-10 diagnoses and self-rated measures. We then conducted two-sample Mendelian Randomization (MR) analyses using SNPs associated with childhood LTCs from existing genome-wide association studies (GWAS) as instrumental variables. Outcomes were: (i) diagnoses of major depressive disorder (MDD) and anxiety disorders or elevated symptoms in MoBa, and (ii) youth-onset MDD using summary statistics from a GWAS in iPSYCH2015 cohort.

RESULTS

Having any childhood LTC phenotype was associated with elevated youth MDD (OR = 1.48 [95% CIs 1.19, 1.85], p = 4.2×10-4) and anxiety disorder risk (OR = 1.44 [1.20, 1.73], p = 7.9×10-5). Observational and MR analyses in MoBa were consistent with a causal relationship between migraine and depression (IVW OR = 1.38 [1.19, 1.60], pFDR = 1.8x10-4). MR analyses using iPSYCH2015 did not support a causal link between LTC genetic liabilities and youth-onset depression or in the reverse direction.

CONCLUSIONS

Childhood LTCs are associated with depression and anxiety in youth, however, little evidence of causation between LTCs genetic liability and youth depression/anxiety was identified from MR analyses, except for migraine.

Physical and psychological symptoms and survey importance in celiac disease

Celiac disease is an autoimmune condition that affects approximately 1% of the worldwide community. Originally thought to be confined mostly to the small intestine, resulting in villous atrophy and nutrient malabsorption, it has more recently been implicated in systemic manifestations as well, particularly when undiagnosed or left untreated. Herein, the physical and psychological symptoms of celiac disease are described and explored. An emphasis is placed on efforts to query prospective and confirmed celiac disease patients via the use of surveys. Suggestions are made regarding the development of efficacious surveys for the purpose of screening for celiac disease in undiagnosed persons, and monitoring efficacy of the gluten-free diet in persons diagnosed with celiac disease. There are broad categories of physical and psychological symptoms associated with celiac disease. There is also an essential interaction between such physical and the psychological symptoms. It is important to capture the association between symptoms, via queries directed toward suspected and confirmed persons with celiac disease. The use of anonymous online surveys can be helpful to determine the qualities and characteristics which may be associated with this condition. It is suggested that personal surveys should be given a greater role in screening and to lessen the time for diagnosis. Querying the subject directly via a survey can provide clues as to the types of symptoms being experienced by those with celiac disease currently, as well as to determine the salient aspects of the symptomatology, which will be useful for rapid screening and monitoring in future work.

Coeliac Disease in Children-A Clinical Review Including Novel Treatment Agents

Coeliac disease (CD) affects almost of 1% of the population, yet remains undiagnosed in the majority. Though the demonstration of enteropathy in duodenal biopsy was traditionally the essential criterion for the diagnosis of coeliac disease, the guidelines published by the European Society of Paediatric Gastroenterology and Nutrition (ESPGHAN) in 2012, and revised in 2020, paved the way to a no-biopsy approach to diagnosis. In a select group of children meeting certain criteria, a definitive diagnosis of CD can now be made without the need for duodenal biopsies. This is being increasingly applied in clinical practice. It is well established that untreated coeliac disease is associated with several chronic adverse health conditions. At present, a strict gluten-free diet remains the only effective treatment for CD. The advances in our understanding of the pathogenesis of CD have led to a search for alternative treatment agents. Several investigational agents are in various phases of clinical trials at present. In this review, we outline the clinical aspects of coeliac disease and summarise various investigational treatment agents.

Love beyond gluten: self-esteem, illness identity, and social support in romantic rejection concerns among adolescents with celiac disease

Introduction

Fear of stigmatization, high perceived partner burden, or refraining from self-disclosure may manifest in romantic rejection concerns among adolescents with celiac disease (CD), potentially impacting their health-related quality of life (HRQOL). This study examined the prevalence, predictors, and consequences of romantic rejection concerns among adolescents and young adults with CD.

Methods

A cross-sectional online survey was conducted among 165 German adolescents and young adults (aged 14-22) with self-reported CD. Participants completed measures of romantic rejection concerns, illness identity, self-esteem, peer support, and CD-specific HRQOL.

Results

Participants reported moderate levels of concerns about the impact of CD on their romantic relationships, with no significant gender differences. Participants involved in romantic relationships expressed lower concerns of rejection, but similar preference for a "gluten-free partner." Hierarchical regression analysis revealed that higher illness acceptance and peer support predicted lower rejection concerns. Significant interactions emerged between self-esteem and illness acceptance, and between self-esteem and peer support. Higher illness acceptance predicted fewer rejection worries only among those with high self-esteem, while peer support played a mitigating role only for those with low self-esteem. Romantic rejection concerns significantly predicted lower CD-specific HRQOL across all domains.

Discussion

Anxieties about CD's impact on romantic relationships are prevalent among adolescents and may hinder their HRQOL. The findings highlight the complex interplay between self-esteem, illness identity, and social support in shaping romantic concerns. Targeted interventions focusing on peer support and fostering positive illness identity are recommended to alleviate rejection fears and improve HRQOL among youth with CD.

A Clinical Investigation on ADHD-Traits in Childhood Celiac Disease

OBJECTIVE

There are no definitive results about either the presence of exact comorbidity between celiac disease (CD) and attention-deficit/hyperactivity disorders (ADHD) or etiology. We intend to screen ADHD-related cognitive and behavioral traits in children with biopsy-proven CD and investigate the possible association of these traits with certain vitamin levels, body-mass index, and gluten-free diet (GFD) compliance.

METHOD

A total of 85 children with biopsy-proven CD (the ages of 8-18 years) were compared with age and sex-matched 72 healthy controls in terms of demographics, psychiatric symptoms, certain vitamin levels, and anthropometric measurements.

RESULTS

ADHD-like cognitive issues, such as inattention and learning difficulties, as well as psychosomatic symptoms and poor prosocial behavior, were all associated with GFD noncompliance in childhood CD.

CONCLUSION

Untreated CD may predispose to ADHD-resembling symptoms. Physicians should be aware of the probability of ADHD misdiagnosing due to ADHD-resembling cognitive and behavioral traits in untreated CD.

Examining the Psychosocial Well-Being of Children and Adolescents With Coeliac Disease: A Systematic Review

This review aimed to synthesize the available literature regarding the psychosocial well-being of children and adolescents with coeliac disease (CD). Research on psychosocial well-being outcomes in children and adolescents with CD under the age of 18 were identified through a systematic search in the PsychInfo, Medline, Embase, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases in July 2021. Outcomes, including health-related quality of life (HRQOL), psychological adjustment, mental health, and social functioning were examined. Changes in outcomes over time and the geographic representation of the included studies were also analyzed. A total of 43 studies were included. Mixed results were found in the domain of HRQOL and mental health. Both challenges with psychological adjustment and adaptive coping strategies were identified. Social functioning was found to be an area of difficulty for children and adolescents with CD. However, there was high heterogeneity in methodology and participant characteristics between studies. This review concluded there were mixed findings regarding the HRQOL and mental health of young people with CD. However, CD and the gluten-free diet initiates a need for psychological adjustment and impacts on social functioning. The review highlights the need for the integration of physical and psychosocial care, and further research to determine the most appropriate screening measures, and the most efficacious psychological interventions for this group. Future research should continue examining changes in psychosocial outcomes over time given the increase in the availability of gluten-free foods and changes in food labeling policies.

Psychological Considerations for Food Intolerances: Celiac Sprue, Eosinophilic Esophagitis, and Non-Celiac Gluten Sensitivity

Several chronic digestive conditions are physiologically based on food intolerance, including celiac disease, nonceliac gluten sensitivity, and eosinophilic esophagitis. Patients are expected to follow medically prescribed diets to eliminate identified food triggers to control symptoms. However, the psychological impacts of these dietary approaches are largely unaddressed in clinical practice. Hypervigilance and anxiety regarding food and symptoms, and disordered eating, may emerge and negatively affect outcomes. Clinicians working with pediatric and adult populations with food intolerances should be aware of these psychological comorbidities, and equally emphasize effective ways to help patients manage the mental and physical aspects of their condition.

"I sort of never felt like I should be worried about it or that I could be worried about it'" an interpretative phenomenological analysis of perceived barriers to disclosure by young people with coeliac disease

OBJECTIVES

There has been little research in the United Kingdom regarding young people's experiences of disclosure of psychological difficulties relating to coeliac disease (CD) to others, particularly healthcare professionals. This study sought to address this systematically with a focus on the lived experiences of young people with CD. This study aimed to gain insight into how paediatric gastroenterology services could improve the patient experience for those with CD and support the identification of patients who may benefit from further psychological support.

DESIGN

This study used interpretive phenomenological analysis (IPA) of patient accounts.

METHODS

Seven young people with CD (aged 11-16 years) were recruited from a UK hospital paediatric gastroenterology service. Semi-structured interviews were carried out and verbatim transcripts were analysed using IPA to explore young people's experiences of CD and why they might feel able or unable to disclose psychological difficulties associated with their condition to clinicians.

RESULTS

Three superordinate themes were interpreted from the data. The first encapsulated experiences of adjusting to the diagnosis within a developmental context, including the role of adults in information provision and the importance of peer support. The second outlined experiences of managing perceived or actual stigma regarding others' perceptions of the condition and themselves. The third incorporated perceived barriers to disclosure relating to power, safety, and beliefs about the role of medical professionals.

CONCLUSIONS

Findings highlight the importance of clinicians continually providing developmentally appropriate information to young people and actively breaking down barriers to disclosure through body language and the use of clear questions regarding emotional experiences.

Anxiety and Depression in Pediatric Patients with Celiac Disease: A Large Cross-Sectional Study

Mental health is a growing concern in pediatric celiac disease (CD). This study utilized the Revised Children's Anxiety and Depression Scale (RCADS) to investigate anxiety and depression symptom rates. Participants were children ages 8 to 17 years (M = 11.7, SD = 2.7; N = 175) with biopsy-proven CD (Median = 1.1 years post-diagnosis, IQR = 0-4) categorized into groups based on the child's age, caregiver or child respondent, presence or absence of comorbidities, and gluten-free diet duration. Self-reported RCADS scores showed 39% of children having clinically significant concerns for anxiety or depression ( P < 0.0001) but only 7% of caregiver-proxy RCADS scores indicated significant concerns for the child's anxiety and 14% for the child's depression. Rates of child-reported anxiety and depression symptoms were significantly higher for those without medical comorbidities than those with ( P = 0.04). Therefore, screening for mental health concerns, particularly anxiety and depression, should be routinely performed in pediatric patients with CD.

Follow-up practices for children and adolescents with celiac disease: results of an international survey

Adequate follow-up in celiac disease is important to improve dietary compliance and treat disease-related symptoms and possible complications. However, data on the follow-up of celiac children is scarce. We aimed to assess current pediatric celiac follow-up practices across Europe. Pediatricians and pediatric gastroenterologists from 35 countries in Europe, Israel, Turkey, and Russia completed an anonymous survey which comprised a 52-item questionnaire developed by the ESPGHAN Special Interest Group on Celiac Disease. A total of 911 physicians, the majority of whom exclusively worked in pediatric care (83%) and academic institutions (60%), completed the questionnaire. Mean age and mean experience with celiac care were 48.7 years (± 10.6) and 15.7 years (± 9.9), respectively. The vast majority (≥ 92%) always assessed anthropometry, dietary adherence, and tissue-transglutaminase IgA-antibodies at every visit, with the first visit being between 3 and 6 months after diagnosis. Other parameters (% always tested) were as follows: complete blood count (60%), iron status (48%), liver enzymes (42%), thyroid function (38%), and vitamin D (26%). Quality of life was never assessed by 35% of the responding physicians. Transition to adult care was mostly completed via a written transition report (37%) or no formal transition at all (27%).Conclusions: Follow-up of celiac children and adolescents in Europe may be improved, especially regarding a more rational use of (laboratory) tests, dietary and QoL assessment, and transition to adult care. Evidence-based advice from international scientific societies is needed. What is Known: • Follow-up in celiac disease is important to treat disease-related symptoms, improve dietary compliance, and prevent possible complications. • There is a lack of consensus about the appropriate follow-up. What is New: • Almost all European physicians assess anthropometry, tissue-transglutaminase IgA-antibodies, and dietary adherence at every visit, but there are large variations in other follow-up aspects. • Follow-up could be improved by a more rational use of (laboratory) tests, increased intention to dietary compliance, and quality of life together with transition programs to adult care.

Different Clinical Features of Celiac Disease in Children, Adolescents, and Adults; a Cross-sectional Study

BACKGROUND

Celiac disease is a common disorder but there are few studies comparing the clinical features of the disease in adults, adolescents and children.

METHODS

Demographic and clinical characteristics of all patients with celiac disease referred to the Celiac Clinic were evaluated and compared in different age groups.

RESULTS

Of 3416 participants, 473 patients were included. 302 (63.8%) were women and 171 (36.2%) were men. Overall, 325 (68.7%) and 411 (86.9%) patients had gastrointestinal (GI) and non-GI manifestations, respectively. The most common symptom in adults was psychiatric problems (66.5%), while abdominal discomfort was the most common symptom in adolescents (45.2%) and children (53.8%). According to age groups, GI manifestations were seen in 79 (66.4%), 119 (59.8%), and 127 (81.9%) children, adolescents, and adults, respectively. Adults had significantly more GI manifestations than the other groups (PR 1.167; 95% CI: 1.094- 1.244; p < 0.001). Non-GI manifestations were seen in 90 (75.6%), 174 (87.4%), and 147 (94.8%) children, adolescents, and adults, respectively. Adults had significantly more non-GI manifestations than the other groups (PR 1.112; 95% CI: 1.060-1.168; p < 0.001).

CONCLUSION

Our study showed that there were significant differences in the clinical features of celiac disease between the different age groups. Considering these results may help plan for future studies.

Celiac Disease Management in the United Kingdom Specialist Pediatric Gastroenterology Centers-A Service Survey

OBJECTIVES

The 2012 European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines on celiac disease (CD) recommended a no-biopsy pathway (NBP) for symptomatic children with high immunoglobin A (IgA)-based anti-tissue transglutaminase (TGA-IgA) titers, positive anti-endomysial antibody and human leukocyte antigen (HLA)-DQ2/DQ8 status. We aimed to understand variations in practice amongst specialist pediatric gastroenterology centers (SPGIC) in the United Kingdom (UK).

METHODS

A survey questionnaire was sent to all UK SPGIC (n = 29) providing endoscopy services for CD diagnosis. It was divided into four main subgroups: analyzing diagnosis of CD through adherence to the ESPGHAN (2012) guidelines, post-diagnosis care and long-term follow-up and discharge from pediatric services.

RESULTS

All 29 responded. NBP was implemented in 28 of 29 centers. Five of 29 centers had already stopped HLA-DQ2/DQ8 testing for NBP diagnosis. Twenty six of 29 centers were performing endoscopy on screening-identified children (mostly asymptomatic, "at-risk" patients). Diagnosis was communicated by a doctor in 65% SPGIC (n = 19). Most centers (n = 23) waited 6-12 months post-diagnosis to start gluten-free oats. Routine vitamin D supplementation was commenced by 4 of 29 centers. All centers repeated TGA-IgA to assess normalization but at varying times post-GFD. Follow-up was with a combination of doctors/dieticians (n = 26). Eleven of 29 centers discharged their patient to primary care.

CONCLUSIONS

There was excellent uptake of ESPGHAN guidelines (2012) in the UK and adherence to guidelines is generally good. Despite published evidence and pragmatic advice from the British Society of Paediatric Gastroenterology Hepatology and Nutrition and National Institute for Health and Care Excellence, significant differences remain in diagnostic and ongoing management practice and are opportunities for research and directive evidence-based follow-up guidance.

Illness Identity in Adolescents With Celiac Disease

OBJECTIVES

The aim was to examine the reliability and validity of the Illness Identity Questionnaire (IIQ) among adolescents with celiac disease (CD), to describe their illness identity characteristics, and to examine relationships between illness identity and self-reported participation in food-related activities and quality of life.

METHODS

Adolescents with CD (n = 91) were recruited for this cross-sectional study via social media interest groups. Participants completed online questionnaires: the IIQ, the CD Children's Activities Chart (CD-Chart), and the Pediatric Quality of Life Inventory (PedsQL).

RESULTS

Internal reliability was established for IIQ items (α = 0.87) and for its 4 components (α = 0.75--0.90). The positive components (acceptance, enrichment) significantly differed from the negative components (rejection, engulfment), t(90) = 11.45, P < 0.001, d = 1.98. Feelings were more positive (M = 3.48, SD = 0.67) than negative (M = 2.06, SD = 0.76). The total IIQ was positively associated with the CD-Chart amount of activities (r = 0.30, P < 0.01) and enjoyment (r = 0.34, P < 0.001) and with the PedsQL social scale (r = 0.53, P < 0.001).

CONCLUSIONS

The IIQ established acceptable reliability and validity. In all, the adolescents with CD exhibited an illness identity profile that was more positive and adaptive than negative. The IIQ can contribute to understanding the developmental status of illness identity during the critical transition process from adolescence to adulthood.

Behavioral and emotional problems in adolescents with constipation and their association with quality of life

Objectives

To assess behavioral and emotional problems in children and adolescents with functional constipation and their relationship with psychological maladjustment and health-related quality of life (HRQoL).

Design

A school-based cross-sectional survey conducted in 8 randomly selected schools from 4 randomly selected districts in Sri Lanka. A previously validated questionnaire was used for data collection. Behavioral and emotional problems were assessed using the Sinhala version of the Child Behavior Check List (CBCL-S/4-18). Constipation was diagnosed by applying the Rome III criteria.

Results

A total of 1000 questionnaires were distributed, and 913 completed questionnaires were included in the analysis. Sixty adolescents (6.5%) had functional constipation. Scores obtained for isolated psychological problems such as withdrawal (3.1 [3.1] vs. 1.9 [2.4], p<0.001), somatic complaints (3.2 [2.8] vs. 2.3 [2.5], p<0.05) anxiety/depression (5.8 [2.5] vs. 3.9 [3.6], p<0.001), social problems (3.0 [2.7] vs. 2.2 [1.9] p<0.001) and attention problems (5.4 [4.1] vs. 3.9 [3.4], p<0.001), and broadband scale of internalization (12.1 [8.4] vs. 8.3 [7.2], p<0.05) and mean total CBCL-S/4-18 score (29.4 [19.5] vs. 23.2 [17.0], p<0.001) were higher in adolescents with functional constipation. Clinical characteristics, socio-demographic and family factors and psychological maladjustment had no relationship with externalization, internalization and total CBCL-S/4-18 score. Internalization (-0.49, p<0.0001), externalization (-0.30, p<0.05), and total CBCL-S/4-18 (-0.44, p<0.001) scores had a negative impact on HRQoL of adolescents with functional constipation.

Conclusions

Adolescents with functional constipation are suffering from significant behavioral and emotional problems. These problems negatively affect their HRQoL.

Update on celiac disease

PURPOSE OF REVIEW

The purpose of this review is to describe current updates in celiac disease.

RECENT FINDINGS

Recent developments in the understanding of the pathogenesis of celiac disease continue to emerge that may implicate the role of gluten exposure. Several studies have shown that the amount of gluten consumed by the infant may affect the age of onset of celiac disease in genetically predisposed individuals. New guidelines from the European Society of Paediatric Gastroenterology, Hepatology and Nutrition allow serology-based celiac diagnosis, omitting endoscopic biopsies, in children. Recent data and updated guidelines in adults no longer support biopsies in all patients who are genetically susceptible with celiac disease who have been identified by serology with clinical signs and symptoms of celiac disease. A new assay was identified in the immune response to epitopes of the tissue transglutaminase-deamidated gliadin peptide complex. In addition, a recent study shows that serum IL-2 elevations correlate with timing and severity of symptoms after gluten ingested in celiac disease patients. Measuring gluten immunogenic peptides (GIPs) in the stool of celiac patients may help monitor adherence to a gluten-free diet (GFD). Of importance, we should be aware that the quality of life is affected in celiac disease patients. During adolescence, the education on the importance of long-term follow-up with an adult gastroenterologist is associated with more successful rates of medical care transition for young adults with celiac disease. Latiglutenase, an orally administered mixture of two gluten-specific recombinant proteases that degrades gluten proteins into small physiologically irrelevant fragments, is currently in a phase 2 trial. Latiglutenase has shown to be safe and effective in reducing symptoms of celiac disease patients upon a GFD with improvement of quality of life. Lastly, a recent study describes a mouse model that is characteristic of celiac disease.

SUMMARY

Our knowledge of celiac disease continues to grow with increasing evidence of contributory factors to its pathogenesis. There is some evidence that the quantity ingested of gluten by the infant effects the age of onset of celiac disease in genetically susceptible patients. Changes have been made to the guidelines in the diagnosis of celiac disease proposed by new studies. Recent studies have shown the significant effects on quality of life for celiac patients. As improved laboratory methods continue to be developed, these tests can have utility in both diagnosis of celiac disease and monitoring adherence to the GFD. Current therapeutic trials offer promising nondietary treatment for celiac patients. The development of an animal model can provide a better understanding of the pathogenesis of celiac disease.

Mental Health Disorders and Psychosocial Distress in Pediatric Celiac Disease

OBJECTIVES

Celiac disease (CeD) has been associated with increased mental health disorders (MHD) and psychosocial distress in children, which may complicate treatment with the gluten-free diet (GFD). This single-center cross-sectional study examined psychological comorbidities in children with CeD to assess psychological needs in CeD care.

METHODS

Participants were 73 parents (95% mothers) of children (ages 3-18) attending a multidisciplinary celiac disease clinic. Parents completed electronic surveys about their child's MHD history, psychological symptoms, and GFD experiences. Rates of MHD were calculated and compared with National Institute of Mental Health population-level data. Differences in psychosocial symptoms and GFD experiences were examined based on child age, time since CeD diagnosis, and MHD.

RESULTS

Thirty-four percentage of children had at least 1 MHD; anxiety disorders (16%, P < 0.001) and attention-deficit/hyperactivity disorder (ADHD; 16%, P = 0.01) were more common than general population rates. More than 1 quarter of parents reported current child psychosocial distress (28%-39%), and approximately half reported parent stress (51%) and financial burden (46%) associated with the GFD. Parents of children with new CeD diagnoses reported lower confidence in the GFD (P < 0.01) but MHD, stress, and financial burden did not differ by time since CeD diagnosis. Children with MHD had more anxiety, anger, overall distress, and parent distress than those without MHD (Ps < .05).

CONCLUSIONS

Comorbid CeD and MHD was common and was associated with increased child and parent psychosocial distress. Our findings emphasize the importance of psychological screening and services to assess for and treat comorbid MHD and to mitigate psychosocial distress associated with the GFD.

The Impact of Celiac Disease on Caregivers' Well-being: An Integrative Review

OBJECTIVES

A diagnosis of celiac disease (CD) requires individuals to adopt a strict gluten-free diet. As children with CD must rely on their caregivers for guidance and support with managing the gluten-free diet, CD may challenge the caregiver's emotional and social well-being. The primary objective of this mixed-methods systematic review was to synthesize research investigating the impact of CD on caregiver's well-being.

METHODS

Five databases were systematically searched from 1990 to 2018 to identify all empirical studies that assessed well-being in caregivers of children (0-18 years) with CD. Qualitative and quantitative data were extracted separately before being integrated to explore key themes across the studies.

RESULTS

Twelve studies were identified that explored the well-being of caregivers of children with CD (3 qualitative, 9 quantitative), reporting on 665 caregivers. The quality of evidence was limited across studies. Synthesis of results revealed 3 themes (Caregiver Responsibility, Caregiver Well-Being and Concern for Child's Health, Implications for the Family) describing the impact of a child with CD on caregiver well-being.

CONCLUSIONS

Caregivers of children with CD may experience difficulties that impact their well-being; specific difficulties identified included the impact of caregivers' social activities, finances, and anxiety. The findings detailed in this review point toward factors that may guide health care personnel to provide support for the caregivers of children with CD.
