Adherence to the Gluten-free Diet and Health-related Quality of Life in an Ethnically Diverse Pediatric Population With Celiac Disease

School Experiences in the Disease Management of Children With Celiac Disease: A Qualitative Study

BACKGROUND

This study was conducted to examine in depth the disease management experiences of school-age children with celiac disease and the effects of family, friends, and teachers on disease management at school.

METHODS

The study employed a qualitative research method using the phenomenology design. Face-to-face, semi-structured, in-depth interviews were conducted with children (n = 14) with celiac disease. The transcripts were analysed using a phenomenological approach and an inductive process.

RESULTS

Three main themes were identified: Individual, Institutional, and Environmental. It was observed that children adapted better to the celiac diet as they got older, but they had difficulty adjusting to the diet in the school environment. In addition, it was found that school-age children had challenges in diagnosing the disease and finding products suitable for the diet in a rural city with limited facilities. It was determined that the approaches of peers and teachers throughout the child's school life affected the disease management levels of children.

CONCLUSION

The study reveals the emotional, cognitive, and behavioural difficulties that children face while adapting to celiac disease and diet, especially in the school environment. The results emphasize that school-age children with celiac disease should not be ignored and that the school nurse plays an essential role in this process.

Are Infants and Children at Risk of Adverse Health Effects from Dietary Deoxynivalenol Exposure? An Integrative Review

Deoxynivalenol (DON) is a foodborne mycotoxin produced by Fusarium molds that commonly infect cereal grains. It is a potent protein synthesis inhibitor that can significantly impact humans' gastrointestinal, immune, and nervous systems and can alter the microbiome landscape. Low-dose, chronic exposure to DON has been found to stimulate the immune system, inhibit protein synthesis, and cause appetite suppression, potentially leading to growth failure in children. At higher doses, DON has been shown to cause immune suppression, nausea, vomiting, abdominal pain, headache, diarrhea, gastroenteritis, the malabsorption of nutrients, intestinal hemorrhaging, dizziness, and fever. A provisional maximum tolerable daily intake (PMTDI) limit of 1 µg/kg/body weight has been established to protect humans, underscoring the potential health risks associated with DON intake. While the adverse effects of dietary DON exposure have been established, healthcare communities have not adequately investigated or addressed this threat to child health, possibly due to the assumption that current regulatory exposure limits protect the public appropriately. This integrative review investigated whether current dietary DON exposure rates in infants and children regularly exceed PMTDI limits, placing them at risk of negative health effects. On a global scale, the routine contamination of cereal grains, bakery products, pasta, and human milk with DON could lead to intake levels above PMTDI limits. Furthermore, evidence suggests that other food commodities, such as soy, coffee, tea, dried spices, nuts, certain seed oils, animal milk, and various water reservoirs, can be intermittently contaminated, further amplifying the scope of the issue. Better mitigation strategies and global measures are needed to safeguard vulnerable youth from this harmful toxicant.

Psychological, Psychiatric, and Organic Brain Manifestations of Celiac Disease

INTRODUCTION

Celiac disease is an autoimmune condition that affects approximately 1% of the population worldwide. Although its main impact often concerns the small intestine, resulting in villous atrophy and nutrient malabsorption, it can also cause systemic manifestations, particularly when undiagnosed or left untreated.

METHOD

Attention is directed to the possible psychological, psychiatric, and organic brain manifestations of celiac disease. Specific topics related to the influence and risk of such manifestations with respect to celiac disease are defined and discussed. Overall, eighteen main topics are considered, sifted from over 500 references.

RESULTS

The most often studied topics were found to be the effect on quality of life, organic brain dysfunction and ataxia, epilepsy, Down syndrome, generalized psychological disorders, eating dysfunction, depression, and schizophrenia. For most every topic, although many studies report a connection to celiac disease, there are often one or more contrary studies and opinions. A bibliographic analysis of the cited articles was also done. There has been a sharp increase in interest in this research since 1990. Recently published articles tend to receive more referencing, up to as many as 15 citations per year, suggesting an increasing impact of the topics. The number of manuscript pages per article has also tended to increase, up to as many as 12 pages. The impact factor of the publishing journal has remained level over the years.

CONCLUSION

This compendium may be useful in developing a consensus regarding psychological, psychiatric, and organic brain manifestations that can occur in celiac disease and for determining the best direction for ongoing research focus.

A Look Into the Future: Are We Ready for an Approved Therapy in Celiac Disease?

As it appears that we are currently at the cusp of an era in which drugs that are new, re-purposed, or "supplements" will be introduced to the management of celiac disease, we need to reflect on whether the framework is set for celiac disease to be treated increasingly with pharmaceuticals as well as diet. This refers to reflecting on the rigor of current diagnostic practices; the limitations of the current standard of care, which is a gluten-free diet; and that we lack objective markers of disease severity. Investigating these issues will help us to identify gaps in technology and practices that could be critical for selecting patients with a well-defined need for an improved or alternative treatment. Both aspects, circumscribed limitations of the gluten-free diet and diagnostics helping to define celiac disease target groups, together with the guiding requirements by the responsible regulatory authorities, will contribute to defining the subgroups of patients with confirmed celiac disease eligible for distinct pharmacologic strategies. Because many patients with celiac disease are diagnosed in childhood, these aspects need to be differentially discussed for the pediatric setting. In this perspective, we aimed to describe these contextual issues and then looked ahead to the future. What might be the major challenges in celiac disease clinics in the coming years once drugs are an option alongside diet? And what will be the future objectives for researchers who further decipher the mucosal immunology of celiac disease? Speculating on the answers to these questions is as stimulating as it is fascinating to be part of this turning point.

Factors Associated With Adherence to a Low Fermentable Carbohydrate Diet in Children With Functional Gastrointestinal Disorders

BACKGROUND

The low-fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet (LFD) has been associated with reduced symptomology in pediatric functional gastrointestinal disorders (FGIDs). The LFD is a complex dietary intervention that may be difficult to follow; thus, there is great interest in determining factors that contribute to adherence.

OBJECTIVE

To examine whether baseline abdominal pain, emotional/behavioral problems, or quality of life predict adherence to the LFD in children with FGIDs.

DESIGN

This was a single-group pre-post intervention design within a larger randomized controlled trial.

PARTICIPANTS/SETTING

Thirty 7- to 12-year-old children with FGIDs were recruited from pediatric gastrointestinal and primary care settings throughout Texas from 2019 to 2021. Evaluated participants were randomized to an LFD intervention as part of a larger randomized controlled trial.

INTERVENTION

Participants received dietary counseling and followed the LFD for 3 weeks.

MEASURES

Emotional or behavioral problems and quality of life were obtained via parent report, and abdominal pain was measured via child report. Adherence was assessed by using diet records and computed by a decrease in consumption of overall FODMAP intake.

STATISTICAL ANALYSES PERFORMED

A hierarchical generalized linear mixed regression model examined factors associated with adherence.

RESULTS

Greater baseline quality of life was associated with better adherence to the LFD (beta coefficient β = -.02, P = 0.03), and baseline emotional/behavioral problems and abdominal pain complaints were not significantly associated with adherence (all Ps > 0.28).

CONCLUSIONS

Higher child quality of life as reported by parents was related to increased adherence to this complex dietary intervention.

Obsessive-Compulsive Symptomatology and Disgust Propensity in Disordered Eating Behaviors of Adolescents with Celiac Disease

BACKGROUND

Considering the importance of underlying psychopathological mechanisms that mediate maladaptive eating behaviors in celiac disease (CD) in the determination of cognitive-behavioral therapeutic approaches, we investigated the impact of obsessive-compulsive symptomatology and disgust propensity on disordered eating attitudes (DEA) and poor gluten-free diet (GFD) compliance in adolescents with CD.

METHOD

Adolescents with biopsy-proven CD (n = 148, aged 12-18 years) were compared with age- and sex-matched controls (n = 104) in terms of eating attitudes/behaviors, obsessive-compulsive symptoms, and disgust propensity, as well as depression and anxiety to rule out depression- and anxiety-related covariates. The clinical implications associated with poor GFD compliance were determined using between-subgroup analysis. Multivariate linear regression and multiple logistic regression were used to identify predictors of DEA and GFD noncompliance, respectively.

RESULTS

In adolescents with CD, DEA was remarkably associated with obsessive-compulsive symptom severity and disgust propensity, especially in contamination and core disgust sub-dimensions. Obsessionality and disgust propensity were independent predictors of DEA, of which the obsessive-compulsive symptom severity was the most decisive predictor of DEA. Higher DEA severity and lower body mass index were independent predictors of poor GFD compliance.

CONCLUSION

Higher obsessionality, accompanied by disgust-related evaluative conditioning processes, may contribute to constructing a cognitive network consisting of hypervigilance and catastrophic interpretations towards benign somatic stimulations, food-related preoccupations, and avoidant behaviors in the disordered eating of adolescents with CD. The reciprocal relationship between lifelong GFD and DEA, mediated by obsessionality and disgust propensity, was supported by current findings that could guide clinicians in the management of maladaptive eating behaviors in adolescents with CD.

Health-related quality of life in children with coeliac disease and in their families: A long-term follow-up study

OBJECTIVES

The aim of the study was to assess long-term health-related quality of life (HRQoL) in children and adolescents with coeliac disease (CD), and their parents.

METHODS

We re-evaluated prospectively the HRQoL and clinical characteristics of 80 families, assessed 5 years earlier, using a disease-specific questionnaire, the CD Dutch Questionnaire (CDDUX), and a generic questionnaire, the Paediatric Quality of Life Inventory (PedsQL).

RESULTS

After a 10-year follow-up, there was no significant change in the total CDDUX and PedsQL scores in children and their parents when compared to the evaluation conducted 5 years earlier. The total CDDUX score reflected a neutral QoL, while for the generic PedsQL was good-very good. The only significant decrease after 5 years was the PedsQL subdomain Emotional functioning. Patients who admitted voluntarily eating gluten reported lower score in CDDUX Diet. Lower scores in subdomain "Physical functioning" (PedsQL) were reported in patients with positivity of TTG or associated diseases.

CONCLUSIONS

The CDDUX score indicated a consistently stable and neutral QoL perception among coeliac patients and caregivers, even after 10-year postdiagnosis, suggesting minimal fluctuations in the impact of CD on disease-specific health domains over time. Furthermore, the consistently good PedsQL score could be a reflection of the resilience of coeliac families in coping with this chronic condition. Gluten-free diet compliance was confirmed to be determinant of HRQoL in the long term. The study confirms the importance of extending surveillance on these patients, possibly using different questionnaires, to assess QoL from different perspectives.

The effect of anxiety and depression levels of children with celiac disease on quality of life

PURPOSE

This study was conducted to examine the effect of anxiety and depression levels on quality of life in children with celiac disease.

DESIGN AND METHOD

This descriptive and correlational study was conducted with 98 children diagnosed with celiac disease who applied to the pediatric outpatient clinic of a university hospital in Eastern Anatolia between September 2021 and August 2022. Data were collected using the State-Trait Anxiety Scale, Depression Scale, and Quality of Life Scale through face-to-face interviews conducted by the researchers. Percentage distribution, mean, independent samples t-test, Pearson correlation analysis and regression analysis were used to analyze the data.

RESULTS

It was found that 62% of the participant children were female and their mean age was 11.69 ± 4.15 years. The mean scores of state anxiety, trait anxiety, depression and quality of life of children with celiac disease were 42.46 ± 5.42 (high), 43.83 ± 7.08 (high), 23.37 ± 4.79 (high) and 43.67 ± 19.67 (low), respectively. Regression analysis revealed that anxiety had a statistically significant relationship with quality of life.

CONCLUSIONS

It was found that children with celiac disease experienced high levels of depression and anxiety along with physical functionality and psychosocial health problems and this negatively affected their quality of life. It is recommended that children with celiac disease should be followed up and supported psychosocially.

PRACTICE IMPLICATIONS

That healthcare professionals can contribute to reducing the depression and axienty and improving the quality of life by strengthening the social support systems of childrens with celiac disease.

Not Quite Meeting the Mark: College Experiences for Patients With Celiac Disease

Strict adherence to a gluten-free diet (GFD), the current treatment for celiac disease (CD), is socially challenging for adolescents, especially in the college setting. We conducted a survey of factors contributing to GFD adherence during college among patients meeting the ESPGHAN criteria for CD. One-hundred-one young adults (18 years and older) were contacted; 59 completed the survey, of which 47 were enrolled or had attended college. The survey was developed by the study team. Most patients were able to maintain strict adherence to the GFD, whereas at college and reported that GF food was available and consistent with expectations. Nearly all participants reported a lack of resources for students with CD. Strong family support helped, and school stress and lack of peer support impeded diet adherence. Although colleges may meet the basic needs of celiac students, the availability and quality of gluten-free options, and improved campus resources are needed.

Cross-Cultural Participation in Food-Related Activities and Quality of Life among Children with Celiac Disease

Children with celiac disease may face challenges in managing a gluten-free diet during their daily interactions and activities. The objective of this study was to compare how children with celiac disease manage their gluten-free diet and participate in food-related activities in Italy and Israel and to assess their quality of life. The previously validated Children's Activities Report (CD-Chart) and the Disease-specific Health-Related Quality of Life Questionnaire for Children with Celiac Disease (CDDUX) were administered in Italy to children aged 8-16 diagnosed with CD (n = 39). The results were compared to data that had been previously gathered from Israeli children with CD (n = 106). The CD-Chart demonstrated satisfactory internal reliability within each cultural group (Italy: α = 0.82; Israel: α = 0.76). Mann-Whitney U-tests indicated significant differences between the two groups. The Italian children exhibited a significantly higher preference for participating in the activities compared to the Israelis (U = 3283.50, p < 0.001). Nonetheless, the Italian children displayed a notable decrease in their level of involvement in the preparation required before engaging in different activities (U = 760.50, p < 0.001). Moreover, they exhibited significantly lower self-determination in this preparatory process compared to the Israeli children (U = 726.00, p < 0.001). Significant group differences were found between the CDDUX children's self-reports and parents' proxy reports in the Israeli group but not in the Italian group. The CD-Chart revealed both shared and distinct participation characteristics in daily food-related activities across different cultural contexts. By incorporating the CD-Chart and the CDDUX, healthcare professionals can emphasize crucial aspects of day-to-day health management and guide them in establishing suitable intervention objectives to enhance effective health self-management.

Health utilities and willingness to pay in adult patients with coeliac disease in Hungary

BACKGROUND

Coeliac disease (CD) is a life-long food-related disorder with a global prevalence of approximately 1%. Patients with CD often experience reduced health-related quality of life that could improve with a strict adherence to a gluten-free diet (GFD).

OBJECTIVES

To obtain visual analogue scale (VAS), time trade-off (TTO) and willingness-to-pay (WTP) values amongst patients with CD.

METHODS

In 2020-2021, a cross-sectional online survey was conducted amongst 312 adult CD patients in Hungary. Patients completed the Gastrointestinal Symptom Rating Scale (GSRS) and evaluated their current health and three hypothetical health state vignettes defined based on dietary adherence using VAS, conventional 10-year TTO and WTP. Multivariate regressions were used to explore the effect of patients' demographic and clinical characteristics on utility and WTP values.

RESULTS

Mean VAS values for current health and 'CD with strict adherence to GFD', 'CD with loose adherence to GFD' and 'CD without GFD' hypothetical health states were 79.69 ± 18.52, 85.36 ± 16.18, 62.44 ± 19.91 and 36.69 ± 25.83, respectively. Corresponding mean TTO utilities were: 0.90 ± 0.19, 0.91 ± 0.20, 0.87 ± 0.23 and 0.76 ± 0.29. Mean annual WTP values for returning to full health were: €845 ± 1077, €648 ± 1002, €862 ± 1135 and €1251 ± 1496. Older age at diagnosis, male sex, more severe gastrointestinal symptoms (GSRS) and having comorbidities were associated with lower VAS and TTO or higher WTP values for current own health (p < 0.05).

CONCLUSION

This is the first study to report TTO utilities for CD health states. Strict adherence to the GFD may result in substantial health gains in symptomatic patients. Utilities and WTP results can be used to estimate benefits of GFD in cost-utility and cost-benefit analyses.

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.

ESPGHAN Position Paper on Management and Follow-up of Children and Adolescents With Celiac Disease

OBJECTIVES

To gather the current evidence and to offer recommendations for follow-up and management.

METHODS

The Special Interest Group on Celiac Diseases of the European Society of Paediatric Gastroenterology Hepatology and Nutrition formulated ten questions considered to be essential for follow-up care. A literature search (January 2010-March 2020) was performed in PubMed or Medline. Relevant publications were identified and potentially eligible studies were assessed. Statements and recommendations were developed and discussed by all coauthors. Recommendations were voted upon: joint agreement was set as at least 85%.

RESULTS

Publications (n = 2775) were identified and 164 were included. Using evidence or expert opinion, 37 recommendations were formulated on: The need to perform follow-up, its frequency and what should be assessed, how to assess adherence to the gluten-free diet, when to expect catch-up growth, how to treat anemia, how to approach persistent high serum levels of antibodies against tissue-transglutaminase, the indication to perform biopsies, assessment of quality of life, management of children with unclear diagnosis for which a gluten-challenge is indicated, children with associated type 1 diabetes or IgA deficiency, cases of potential celiac disease, which professionals should perform follow-up, how to improve the communication to patients and their parents/caregivers and transition from pediatric to adult health care.

CONCLUSIONS

We offer recommendations to improve follow-up of children and adolescents with celiac disease and highlight gaps that should be investigated to further improve management.

Predictors of Compliance to Gluten-Free Diet in Children with Celiac Disease

Background: Celiac disease (CD) is a common autoimmune disorder that presents intestinal and extra-intestinal symptoms. It is also associated with cardiovascular diseases and malignancies, and mortality risk. The only way to control the disease is to follow a strict gluten-free diet (GFD) for the rest of life. Objectives: This survey aimed to investigate GFD non-adherence and causes in the pediatric setting. Methods: In this study, 187 children aged between 2.5 to 14 years old with a confirmed diagnosis of CD at least for a year were studied using a questionnaire-based interview in a census study between 2018 to 2019 in a referral center in southern Iran. Results: About 40% of children adhered to a GFD poorly. This group significantly complained of more symptoms than the group with high adherence. Improper access was the most important cause of non-adherence to a GFD. The mean current weight and at the time of diagnosis as well as the mean current BMI and at the time of diagnosis in the non-adherent group were significantly lower than the adherent group. However, IgA anti-transglutaminase antibodies and histopathologic examination did not change remarkably. Furthermore, no significant relationship was found between following a GFD and age, age at the time of diagnosis, gender, and parental educational status. Conclusions: According to our results, inaccessibility, high costs, and lack of food labeling were the primary reasons for non-adherence to GDF. Therefore, to increase compliance, easy access to GFD with proper food labeling and suitable price should be implemented.

Review on pediatric coeliac disease from a clinical perspective

Coeliac disease is an immune-mediated condition characterized by chronic inflammation of the small bowel with villous atrophy driven by gluten ingestion in genetically predisposed individuals. It occurs frequently in both children and adults, affecting 1-4% of the population. The disease is associated with both gastrointestinal and extra-intestinal symptoms related to malabsorption and/or immune activation, and autoantibodies to tissue transglutaminase. Removal of gluten from the diet results in resolution of symptoms and enteropathy in the majority of patients. A good diagnostic work-up is important to avoid unnecessary restrictive diets in children. In this review on pediatric coeliac disease, we address epidemiology including predisposing environmental factors and possible preventive strategies, as well as the clinical presentation, diagnosis and follow-up. What is Known: •Primary prevention of coeliac disease is not possible; however, secondary prevention by targeting high-risk groups is recommended. •The diagnosis is safe without duodenal biopsies if specific conditions are met, also in asymptomatic children. What is New: •HLA-DQ typing is not routinely required for the diagnosis, whereas it can rule out coeliac disease if HLA-DQ2 and HLA-DQ8 are absent. •Follow-up could be improved by a more rational use of (laboratory) tests, increased intention to dietary compliance and quality of life.

Family ties: the impact of celiac disease on children and caregivers

PURPOSE

To evaluate the impact of celiac disease (CD) and the gluten-free diet (GFD) on the health-related quality of life (HRQoL) in children with CD in the United States using validated measures. We hypothesize that CD negatively impacts the child and caregivers' HRQoL.

METHODS

Participants included children with a confirmed diagnosis of CD and their caregivers (n = 246) seen in a CD multidisciplinary clinic. Caregivers completed the Pediatric Quality of Life (PedsQL) parent-proxy scale to report on their child's HRQoL and the Family Impact Module (FIM), which assesses the impact of caring for a child with a chronic illness. Their children completed the age-appropriate PedsQL. PedsQL and FIM results were compared to published data for children with gastroenterological conditions and a healthy cohort using non-parametric tests.

RESULTS

Children with CD reported significantly lower HRQoL than reports from healthy controls across all PedsQL domains (P < 0.001, Cohen d = 0.8), and lower compared to children with other organic gastrointestinal conditions in Social Functioning (P < 0.001, Cohen d = 0.5) and overall Psychosocial Functioning (P < 0.001, Cohen d = 0.3) domains. Results from the caregiver's report on their own HRQoL were significantly worse than that reported by historical controls in the domains of Communication (P < 0.001, Cohen d = 0.3) and Worry (P < 0.001, Cohen d = 0.8), yet similar on all other domains.

CONCLUSIONS

In our population, CD is associated with low HRQoL scores for both children and their caregivers. Screening children and families for HRQoL can identify patients and families in need of additional support in this higher-risk population.

Effect of lactose intolerance severity on food intake and quality of life in adults with lactose intolerance in Turkey

Purpose

Lactose intolerance is lactose digestive disorder due to lactase enzyme deficiency. This can affect the quality of life by restricting the intake of certain foods. The aim of this study is to show the lactose intolerance to the restriction in food intake and quality of life.

Design/methodology/approach

This study was conducted with adults aged 18–60 years. A survey was used to gather information on the demographic characteristics of the patients and their symptoms related to lactose intolerance. In addition, the Visual Analog Scale was administered to identify common symptoms and the World Health Organization Quality of Life (WHOQOL)-Bref Quality of Life Scale to determine their quality of life.

Findings

The average quality of life subscale scores was 56.25 ± 14.06 for physical, 58.29 ± 11.72 for mental, 63.28 ± 21.35 for social and 62.36 ± 16.37 for environmental. When VAS scores obtained for the common digestive system symptoms in lactose intolerance were compared with Quality of Life scores; it was found that physical life quality scores decreased (r = −0.239, p = 0.030) as the complaints of diarrhea increased and physical and environmental life quality decreased (r = −0.316, p = 0.004/r = −0.277, p = 0.012, respectively) as abdominal pain increased.

Originality/value

People reduce dairy consumption due to digestive system complaints. Therefore, it is important to inform the people about the effects of lactose intolerance because discomfort caused by intolerance can affect nutrient intake and lower the quality of life.

Nutritional considerations of a paediatric gluten-free food guide for coeliac disease

The gluten-free (GF) diet is the only treatment for coeliac disease (CD). While the GF diet can be nutritious, increased reliance on processed and packaged GF foods can result in higher fat/sugar and lower micronutrient intake in children with CD. Currently, there are no evidence-based nutrition guidelines that address the GF diet. The objective of this cross-sectional study was to describe the methodological considerations in forming a GF food guide for Canadian children and youth (4–18 years) with CD. Food guide development occurred in three phases: (1) evaluation of nutrient intake and dietary patterns of children on the GF diet, (2) pre-guide stakeholder consultations with 151 health care professionals and 383 community end users and (3) development of 1260 GF diet simulations that addressed cultural preferences and food traditions, diet patterns and diet quality. Stakeholder feedback identified nutrient intake and food literacy as important topics for guide content. Except for vitamin D, the diet simulations met 100 % macronutrient and micronutrient requirements for age–sex. The paediatric GF plate model recommends intake of >50 % fruits and vegetables (FV), <25 % grains and 25 % protein foods with a stronger emphasis on plant-based sources. Vitamin D-fortified fluid milk/unsweetened plant-based alternatives and other rich sources are important to optimise vitamin D intake. The GF food guide can help children consume a nutritiously adequate GF diet and inform policy makers regarding the need for nutrition guidelines in paediatric CD.

FODMAP intake in children with coeliac disease influences diet quality and health-related quality of life and has no impact on gastrointestinal symptoms

Children with coeliac disease (CD) following the gluten-free diet may experience ongoing gastrointestinal symptoms despite strict adherence. The study objective was to evaluate the association between foods high in fermentable oligo/di/monosaccharides, and polyols (FODMAP) and gastrointestinal symptoms, and the potential implications to diet quality and health-related quality of life in CD children. Dietary intake was studied in age-sex matched children 5-18 years (CD, n = 46; non-coeliac mild chronic gastrointestinal complaints [GIC], n = 46; healthy controls [HC], n = 46). CD children consumed fewer foods high in FODMAPs compared to GIC and HC (p < .0001). FODMAP intake was not related to gastrointestinal symptoms in CD children (p > 0.05) but was positively associated with child health-related quality of life (p < 0.05). FODMAP intake from fruits and vegetables was positively associated with diet adequacy and total diet quality in CD children (p < 0.05). FODMAP intake may influence diet quality and health-related quality of life but has no impact on gastrointestinal symptoms in CD children.

Factors Affecting Compliance to a Gluten-Free Diet in Pediatric Populations with Celiac Disease

Celiac disease (CD) is a multisystemic autoimmune disorder triggered by gluten, and the only known remedy available for this malady is a gluten-free diet (GFD). Therefore, we performed a systematic review to correlate the influence of different factors in compliance to a GFD. We searched PubMed database, from inception to April 2019. As inclusion criteria we considered population under 18 years, confirmed diagnosis of CD without related comorbidities and the study objective being the factors affecting compliance to a GFD. The variables compared were age, parent's education level, parental knowledge about CD, family type, celiac association membership, quality of life, and perception of difficulties in maintaining a GFD. We identified 1,414 articles, 35 articles were eligible for full text assessment and 12 were included in the study since they studied similar variables. Our work has found some limitations namely a variety of methods to assess GFD compliance, a limiting definition of compliance, a parental bias in data, an absence of standardization in age categories, and a majority of studies being observational in their nature. Age as well as parental knowledge of CD and family type are key factors in pediatric GFD compliance. Nevertheless environmental, social, and family factors were also related with compliance. Further studies are needed to fully disclose the causality relation between these factors and compliance.

Health-Related Quality of Life 10 Years after Liver Transplantation: A Longitudinal Retrospective Review

As survival post-liver transplantation (LTx) improves, it becomes increasingly important to understand how long-term health-related quality of life (HRQOL) is impacted. This was a longitudinal review examining HRQOL measured by Pediatric Liver Transplant Quality of Life (PeLTQL) in children between 8-17 years who underwent LTx (1.4 [0.8–3.3] years) at least one year prior to assessment. Demographic, medical, anthropometric, and HRQOL data (self-reported and parent proxy) were retrospectively collected over four years (2014–2017) at annual LTx clinic visits. The study included 35 patients (18M, 17F) and their parents/guardians. Parent-proxy and child PeLTQL scores (total, subdomain) showed good to excellent agreement (p > 0.05) and did not change over four years (p > 0.05). Younger age (<12 years) and Caucasian ancestry were associated with higher parental and self-reported perceptions of HRQOL, respectively (future health, coping and adjustment, total scores). Parent perceived lower HRQOL in social–emotional sub-domain (p = 0.03) and the child reported lower sub-domain scores related to coping and adjustment (p = 0.04) when the child was noted to have co-morbid conditions related to mental health and neurocognitive development (25.7%). While child–parent perceptions of HRQOL in a multi-ethnic population of pediatric LTx recipients remain unchanged 10 years post-LTx, adolescents of non-Caucasian ancestry remain a population at risk for lower HRQOL.

Health-related quality of life using specific and generic questionnaires in Spanish coeliac children

Background

We aimed to compare the perception of health-related quality of life (HRQOL) and related factors in Spanish coeliac children and their parents, using two questionnaires, the generic KIDSCREEN-52 and the specific the Celiac Disease DUX (CDDUX), and to assess the correlation between them.

Methods

Coeliac children, aged 8-18, who are members of the Madrid Coeliac Association (MCA) and their parents, answered the Spanish version of the CDDUX and KIDSCREEN-52 questionnaires via e-mail. CDDUX was answered by 266 children and 428 parents and KIDSCREEN-52 by 255 children and 387 parents. Linear regression models were fitted to evaluate the association of demographic and clinical factors with HRQOL scores. CDDUX scores were compared with the subjective perception of health status assessed by the first question of KIDSCREEN-52. The correlation between the questionnaires was analysed.

Results

We found that the main factors that negatively affected HRQOL were having social or economic difficulties associated with following the diet and having transgression-related symptoms. The maximum correlation between the questionnaires was 0.309 and − 0.254 in parents and children respectively.

Conclusions

Although there is a poor correlation between the two questionnaires, both agreed that the main concerns of the respondents were related to the social and economic difficulties of following the diet. It would be interesting to use both types of questionnaires in order to perform a more complete assessment of HRQOL in coeliac children.

Systematic Review With Meta-analysis of the Health-related Quality of Life in Children With Celiac Disease

OBJECTIVES

The aim of this article is to systematically review and meta-analyze the published data on the comparison of the health-related quality of life (HRQOL) in children and adolescents with celiac disease (CD) and healthy children. Moreover, the meta-analysis was performed to compare the parent proxy-report and child self-report of HRQOL.

METHODS

The databases of PubMed, Embase, Scopus, and Cochrane library were searched from inception to April 2019 to identify observational studies that evaluated the HRQOL in children with CD. Studies comparing the HRQOL in celiac patients and healthy children, and also comparing the parent's proxy-report and child self-report of HRQOL were included. Comprehensive meta-analysis software was used for statistical analysis.

RESULTS

Through our systematic search, 26 articles met our predefined inclusion criteria. The result of our meta-analysis on studies using the PedsQL questionnaire showed that the total score of HRQOL was not significantly different between celiac patients and healthy controls (SMD (95% confidence interval; CI]: -0.11[-0.45 to 0.23], P = 0.52). The result of our meta-analysis showed that the parents reported the child's diet and communication scores lower than that of children. Only 4 out of 11 studies showed a significant correlation between HRQOL and gluten-free diet (GFD) compliance and 2 of 4 studies showed a significant negative association between HRQOL and age at diagnosis.

CONCLUSIONS

The results of the present study showed that there was no significant difference between children with CD and healthy controls regarding HRQOL. Moreover, the parental perception of their children's HRQOL was lower than the children's perception.

Literature Review: Dietary Intervention Adherence and Adherence Barriers in Functional Gastrointestinal Disorder Studies

Dietary management is key in controlling functional gastrointestinal disorders (FGIDs) symptoms. However, the degree to which patients with FGIDs in clinical studies adhere to dietary recommendations is unknown. Our aim was to evaluate adherence, dietary education, and adherence-related factors in FGIDs dietary intervention trials. A literature search was performed using MEDLINE, Google Scholar, and SCOPUS for clinical trials evaluating dietary management of FGIDs. Full manuscripts published from January 2000 through August 2018 were reviewed. Data including definitions of adherence and rates, study design, dietary education, use of a dietitian, provision of study foods, potential adherence barriers, and dropouts were captured. A total of 21 publications were included. Fifteen (67%) focused on the low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet, 5 (24%) on fiber supplementation, and 1 (9%) on a low carbohydrate diet. Fifteen (71%) were randomized controlled trials. Meals/supplements were provided to the study participants in 27%, 80%, and 100%, of the low FODMAP, fiber, and low carbohydrate studies, respectively, which appeared to significantly enhance adherence (P<0.03). Eighteen studies (81%) provided either written or oral diet information to study participants. Overall, only 10 publications (48%) provided adherence data. Nine (60%) of the low FODMAP studies provided adherence data (range, 30% to 100%); ranges could not be calculated for the other dietary trials. The most common method to measure adherence was via food diaries. Therefore, adherence is not often measured in FGIDs dietary intervention clinical trials; when reported, rates of adherence range widely. Studies providing food had the highest adherence rates.

Rate, Risk Factors, and Outcomes of Nonadherence in Pediatric Patients With Celiac Disease: A Systematic Review

BACKGROUND AND AIMS

The only treatment for celiac disease is strict adherence to a gluten-free diet (GFD). We performed a systematic review to investigate the rate of adherence to a GFD in children with celiac disease, risk factors that affect adherence, and outcomes of non-adherence.

METHODS

We searched PubMed, Cochrane Library, EBSCO, and Scopus for studies through January 2019. We included observational studies of ≥50 children diagnosed with celiac disease and recommended for placement on a GFD. We collected data on adherence assessment (self-report, serology tests, structured dietary interview, biopsies, or assays for gluten immunogenic peptides), risk factors, and outcomes related to adherence. Findings were presented with medians, range, and a narrative synthesis.

RESULTS

We identified 703 studies; of these, 167 were eligible for full-text assessment and 49 were included in the final analysis, comprising 7850 children. Rates of adherence to a GFD ranged from 23% to 98%. Comparable rates (median rates of adherence, 75%-87%) were found irrespective of how assessments were performed. Adolescents were at risk of non-adherence and children whose parents had good knowledge about celiac disease adhered more strictly. Non-adherence associated with patient growth, symptoms, and quality of life.

CONCLUSION

In a systematic review of 49 studies of children with celiac disease, we found substantial variation in adherence to a GFD among patients. Rate of adherence was not associated with method of adherence measurement, so all methods appear to be useful, with lack of consensus on the ideal metric. Studies are needed to determine the best method to ensure adherence and effects on long-term health.

Health-related Quality of Life in Newly Diagnosed Pediatric Patients With Celiac Disease

OBJECTIVES

Celiac disease (CD) is a common chronic condition with potential adverse physical and psychosocial implications for affected children. The study purpose was to characterize health-related quality of life (HRQOL) in a large sample of pediatric patients with newly diagnosed CD using the PedsQL 4.0 Generic Core Scales, and compare it to that of healthy children and children with nonceliac gastrointestinal (GI) conditions using historic data.

METHODS

The PedsQL was administered to 159 children with newly diagnosed CD and their parents at either the time of diagnostic esophagogastroduodenoscopy or before their initial dietitian appointment for gluten-free diet teaching. Mean parent-report and self-report PedsQL summary and subscale scores were calculated, then compared to published means from a sample of healthy children and a sample of children with nonceliac GI symptoms using 1-sample t tests.

RESULTS

Compared to the healthy children, those with newly diagnosed CD had lower Total Scores, Physical Health, Psychosocial Health, Emotional Functioning, and School Functioning on parent report (P < 0.008) with similar findings on self-report. Within the CD sample, clinically significant scores were found in 55.9% for School Functioning, 62.7% for Physical Health, 54.4% for Emotional Functioning, 43.7% for Social Functioning, and 49% for Total Score.

CONCLUSIONS

Children and adolescents with newly diagnosed CD had lower HRQOL than healthy children and similar HRQOL to that of patients with nonceliac GI conditions. Patients with deficits in domains such as school or emotional functioning may benefit from early interventions including a Section 504 plan or meeting with a psychologist or social worker.

Measuring Quality of Life in Parents or Caregivers of Children and Adolescents with Celiac Disease: Development and Content Validation of the Questionnaire

Celiac disease (CD) is an autoimmune disorder triggered by the ingestion of gluten and affects approximately 1% of the global population. Currently, the only treatment available is lifelong strict adherence to a gluten-free diet (GFD). Chronic diseases such as CD affect patients and their family members’ quality of life (QoL); particularly parents and caregivers who play an essential role in the child’s care and treatment. A higher level of psychological distress has been found in the parents of children with chronic ailments due to limited control over the child’s daily activities and the child’s illness. In this context, the validation of a specific questionnaire of QoL is a valuable tool to evaluate the difficulties faced by parents or caregivers of children with this chronic illness. A specific questionnaire for this population can elucidate the reasons for stress in their daily lives as well as the physical, mental, emotional, and social impact caused by CD. Therefore, this study aimed to develop and validate a specific questionnaire to evaluate the QoL of parents and caregivers of children and adolescents with CD. Overall results showed that a higher family income resulted in a higher score of the worries domain. In addition, having another illness besides CD decreased the QoL (except in the worries domain). The other variables studied did not present a statistically significant impact on the QoL, which was shown to be low in all aspects. Knowledge of the QoL is important to help implement effective strategies to improve celiac patients’ quality of life and reduce their physical, emotional, and social burden.

Health related quality of life among Saudi children and adolescents with celiac disease

BACKGROUND/AIMS

Celiac disease (CD) is an immune-mediated enteropathy triggered by gluten ingestion in genetically susceptible individuals. This study reports on the quality of life (QOL) of Saudi children and adolescents with CD.

PATIENTS AND METHODS

This is a case control study that included Saudi patients with CD, aged 9-18 years, who attended CD Clinic at KAU between February 2017 and July 2018. The study was conducted using the Short-Form (SF-36) questionnaire for all candidates, CD-specific QOL questionnaire for the CD patients group, and CD screen questionnaire for the control group.

RESULTS

Overall, 354 subjects were studied (111 CD patients and 243 control). Female subjects constituted 56.8% of both patient and control groups. In the generic SF-36 questionnaire, QOL was comparable between patients and controls in all domains except for the general health domain, which showed difference in favor of the controls (55.01 ± 26.41 and 62.96 ± 18.16, P = 0.005). We also found that males have lower QOL scores in the domains comprising health change (P = 0.02), physical functioning (P = 0.04, role functioning/emotional and emotional well-being (P = 0.049). The CD-specific QOL showed excellent and good scores for 79.3% of patients overall in the tested domains. Patients with poor adherence showed poor QOL in all generic (SF-36) domains but not in CD-specific domains.

CONCLUSION

The HRQOL for Saudi CD children on GFD is generally comparable to the healthy control with exception of the general health domain. Adherence to the GFD improves the generic (SF-36) QOL domains.

Impact on Health-Related Quality of Life in Adults with Eosinophilic Gastritis and Gastroenteritis: A Qualitative Assessment

BACKGROUND

Eosinophilic gastritis (EG) and eosinophilic gastroenteritis (EGE) are chronic immune-mediated conditions of the digestive tract, which affect the stomach only, or the stomach and small intestines, respectively. Though these disorders are uncommon, they are being increasingly recognized and diagnosed. While health-related quality of life (HRQOL) has been evaluated in other eosinophilic gastrointestinal diseases, this study is the first to describe HRQOL impacts unique to EG/EGE.

AIMS

This study aims to qualitatively describe experiences of adults diagnosed with EG and EGE. We aim to identify impacts on HRQOL in this population in order to inform clinical care and assessment.

METHODS

Seven patients diagnosed with EG or EGE participated in semi-structured interviews assessing common domains of HRQOL.

RESULTS

Four distinct themes emerged from qualitative analyses, which represent impacts to HRQOL: the psychological impact of the diagnosis, impact on social relationships, financial impact, and impact on the body. These generally improved over time and with effective treatment.

CONCLUSIONS

This study demonstrated that patients with EG/EGE experience impacts to HRQOL, some of which differ from HRQOL of other eosinophilic gastrointestinal diseases. These results support the development of a disease-specific measure, or adaptation of an existing measure, to assess HRQOL in EG/EGE.
