Transition from childhood to adulthood in coeliac disease: the Prague consensus report

Frequency and Predictors of Successful Transition of Care for Young Adults With Childhood Celiac Disease

OBJECTIVES

Transition from pediatric to adult care for individuals with chronic conditions is important to prevent gaps in care, though this has not been well-studied in celiac disease (CD). The aim of this study was to discern rates and predictors of successful transition of care for young adults with childhood-diagnosed CD.

METHODS

An anonymous 21-question online survey was sent to individuals on our center's email contact list seeking responses from those ages 18 to 25 years diagnosed with CD before age 18 years. Information collected included method of diagnosis, demographics, CD-related care, reasons for not seeking care, and symptoms.

RESULTS

Respondents (n = 98), 70% women, had a median age of 21 years (IQR 19--23 years). The majority were full or part-time students (67%; 95% CI 59%-77%). Only 31% of respondents had successfully transitioned to an adult CD provider. Some 37% (95% CI 29%-48%) were not receiving any CD medical care. An older age at diagnosis was associated with successful transition to adult gastroenterology (P = 0.002) as well as with greater symptom scores (P = 0.002). Receiving a referral for ongoing adult CD care predicted successful transition to an adult provider (odds ratio [OR] 3.92, 95% CI 1.58-9.72).

CONCLUSIONS

Transition of care for young adults with CD is inconsistent, particularly among asymptomatic patients. Receipt of a referral for an adult provider significantly improves follow-up rates.

Current Evidence in the Diagnosis and Treatment of Children With Celiac Disease

Recent statistics report that 3 million people, or 1% of the population in the United States (U.S.), are affected by celiac disease (CD). In addition, in the U.S., as many as 1 in 80 children is affected with CD. However, CD can be challenging to diagnose and many children are not correctly diagnosed or live without a diagnosis for several years. Symptoms, if present, are often nonspecific and may be common manifestations of many pediatric illnesses. The purpose of this review is to examine the current evidence regarding incidence, pathophysiology, diagnosis, and treatment of a child with CD. Clinical implications for nurses caring for children and families are discussed.

Celiac Dietary Adherence Test simplifies Determining Adherence to a Gluten-free Diet in Swedish Adolescents

OBJECTIVES

The aims of the study were to ascertain whether the Celiac Dietary Adherence Test (CDAT) could contribute in determining adherence to a gluten-free diet in patients with celiac disease and to evaluate the diet adherence and well being of a study population 5 years after a celiac disease screening known as "Exploring the Iceberg of Celiacs in Sweden."

METHODS

Through the screening, 90 adolescents (born 1997) were diagnosed with biopsy-proven celiac disease at 12 years of age. Of them, 70 (78%) came to a 5-year follow-up where anti-tissue transglutaminase antibodies 2 was tested and a questionnaire was filled in, including CDAT, which consists of 7 questions related to adherence. Nonparametrical tests were used to determine associations between adherence measures.

RESULTS

Among the adolescents, 86% were adherent to a gluten-free diet 5 years after screening, 38% reported their general well being as excellent, 50% very well, and 12% well. Statistically significant associations were seen between anti-tissue transglutaminase antibodies 2 and the CDAT score (P = 0.033), and the self-reported adherence question and the CDAT score (P < 0.001).

CONCLUSIONS

The screening-detected adolescents reported a high level of well being and adherence to a gluten-free diet 5 years after screening. We conclude that the CDAT can be used in clinical practice as an estimation of adherence to a gluten-free diet. It would be most suitable to use in conjunction with currently used adherence measures, but can also be used as a stand-alone method when others are not accessible.

Diagnosing Celiac Disease: Towards Wide-Scale Screening and Serology-Based Criteria?

Celiac disease is one of the most common food-related chronic disorders in children. Unfortunately, this multifaceted disease is challenging to recognize and remains markedly underdiagnosed. Screening of either known at-risk groups or even the whole population could increase the suboptimal diagnostic yield substantially. Many recent guidelines recommend screening of at least selected risk groups, but more wide-scale screening remains controversial. The increasing prevalence of celiac disease and the development of autoantibody assays have also led to a gradual shift in the diagnostics towards less invasive serology-based criteria in a subgroup of symptomatic children. The main open questions concern whether these criteria are applicable to all countries and clinical settings, as well as to adult patients. On the other hand, widening screening and the mistaken practice of initiating a gluten-free diet before the appropriate exclusion of celiac disease increase the number of borderline seropositive cases, which may also challenge the classical histopathological diagnostics. Sophisticated diagnostic methods and a deeper understanding of the natural history of early developing celiac disease may prove useful in these circumstances.

Psychological Comorbidities in Childhood Celiac Disease: A Systematic Review

OBJECTIVES

Mental health disorders comorbid to chronic illness are associated with higher medical care utilization and costs for adults and children. Celiac disease (CD) has a substantial perceived treatment burden and is associated with higher rates of psychopathology in adults. However, establishing the risk for psychological comorbidities in children with CD is still needed. This study aimed to review existing research on mental health concerns in pediatric CD and propose an initial psychosocial research and clinical agenda.

METHODS

Databases, including Scopus and PubMed. Additional publications were accessed and reviewed from the references provided by initially identified publications. Two investigators screened studies using predetermined criteria (peer-reviewed, published in English, electronically available, inclusive of child participants, and examining CD). One investigator initially extracted data, with subsequent review by the second investigator.

RESULTS

Twenty-six publications met criteria for the current review (16 case-control, 9 observational, and 1 clinical trial). Publications were heterogeneous in symptoms examined, methodology, and population characteristics. Several studies found elevated risk for psychological comorbidities and poorer quality of life in children with CD. However, many studies were limited by small sample sizes and inconsistent or nonvalidated approaches to measuring psychological symptoms.

CONCLUSIONS

Many existing studies have found increased prevalence of comorbid CD and psychological symptoms or diagnoses. Therefore, screening for psychological symptoms in CD and also screening for CD in psychological clinic populations is needed. We have identified the importance for further study of mechanisms and risk, and identify preliminary priorities for psychosocial research and clinical care in pediatric CD.

Daily Life Restrictions are Common and Associated with Health Concerns and Dietary Challenges in Adult Celiac Disease Patients Diagnosed in Childhood

The prevalence and associated factors of daily life restrictions due to a gluten-free diet in adult celiac disease patients diagnosed in childhood are poorly known. We investigated these issues by collecting the medical data of 955 pediatric patients and sending questionnaires evaluating various health outcomes to the 559 patients who had reached adulthood. Of the 231 respondents, 46% reported everyday life restrictions caused by dietary treatment. Compared with those without restrictions, they more often had anemia at diagnosis (37% vs. 22%, p = 0.014), but the groups were comparable in other diagnostic features. In adulthood, patients with restrictions reported more overall symptoms (32% vs. 17%, p = 0.006), although the symptoms measured with the Gastrointestinal Symptom Rating Scale questionnaire were comparable. Despite strict dietary adherence in both groups, the experience of restrictions was associated with dietary challenges (34% vs. 9%, p < 0.001), health concerns (22% vs. 13%, p = 0.050), and lower vitality scores in the Psychological General Well-Being questionnaire. The groups did not differ in their current age, socioeconomic status, family history of celiac disease, general health or health-related lifestyle, the presence of co-morbidities, or regular follow up. Our results encourage healthcare professionals to discuss the possible health concerns and dietary challenges with patients to avoid unnecessary daily life restrictions, especially when young patients start to take responsibility for their treatment.

Diminished quality of life among adolescents with coeliac disease using maladaptive eating behaviours to manage a gluten-free diet: a cross-sectional, mixed-methods study

BACKGROUND

Certain approaches to managing a strict gluten-free diet (GFD) for coeliac disease (CD) may lead to impaired psychosocial well-being, a diminished quality of life (QOL) and disordered eating. The present study aimed to understand adolescents' approaches to managing a GFD and the association with QOL.

METHODS

Thirty adolescents with CD (13-17 years old) following the GFD for at least 1 year completed the Celiac Dietary Adherence Test (CDAT) and QOL survey. Their approaches to GFD management were explored using a semi-structured interview, where key themes were developed using an iterative process, and further analysed using a psychosocial rubric to classify management strategies and QOL. CDAT ratings were compared across groups.

RESULTS

Gluten-free diet management strategies were classified on a four-point scale. Adaptive eating behaviours were characterised by greater flexibility (versus rigidity), trust (versus avoidance), confidence (versus controlling behaviour) and awareness (versus preoccupation) with respect to maintaining a GFD. Approximately half the sample (53.3%) expressed more maladaptive approaches to maintaining a GFD and those who did so were older with lower CD-Specific Pediatric Quality of Life (CDPQOL) scores, mean subscale differences ranging from 15.0 points for Isolation (t = 2.4, P = 0.03, d.f. = 28) to 23.4 points for Limitations (t = 3.0, P = 0.01, d.f. = 28).

CONCLUSIONS

Adolescents with CD who manage a GFD with maladaptive eating behaviours similar to known risk factors for feeding and eating disorders experience diminished QOL. In accordance with CD management recommendations, we recommend ongoing follow-up with gastroenterologists and dietitians and psychosocial support referrals, as needed.

Follow-up of Celiac Disease

Currently, the only effective treatment for celiac disease is complete removal of gluten from the diet. However, patients need to follow a strict gluten-free diet that results in symptomatic, serologic, and histologic remission in most patients. Histologic remission is usually complete in children, but recovery is slower and more frequently incomplete in adults. When remission has been achieved, yearly follow-up is recommended for adults, children, and adolescents. This article deals with conventional strategies used in order to follow-up patients on treatment and aiming to obtain the best clinical outcome.

Synthetic Neoepitopes of the Transglutaminase-Deamidated Gliadin Complex as Biomarkers for Diagnosing and Monitoring Celiac Disease

BACKGROUND & AIMS

Celiac disease (CeD) has characteristics of an autoimmune disease, such as increased antibody levels to tissue transglutaminase (tTG). However, assays to measure these biomarkers in blood samples do not identify patients with sufficient accuracy for diagnosis or monitoring of CeD. We aimed to discover biomarkers of CeD derived from neoepitopes of deamidated gliadin peptides (DGP) and tTG fragments and to determine if immune reactivity against these epitopes can identify patients with CeD with mucosal healing.

METHODS

We analyzed serum samples from 90 patients with biopsy-proven CeD and 79 healthy individuals (controls) for immune reactivity against the tTG-DGP complex (discovery cohort). A fluorescent peptide microarray platform was used to estimate the antibody-binding intensity of each synthesized tTG-DGP epitope. We validated our findings in 82 patients with newly diagnosed CeD and 217 controls. We tested the ability of our peptide panel to identify patients with mucosal healing (based on the histologic analysis) using serum samples from patients with treated and healed CeD (n = 85), patients with treated but unhealed CeD (n = 81; villous atrophy despite a adhering a gluten-free diet), patients with untreated CeD (n = 82) and disease controls (n = 27), villous atrophy without CeD), and healthy controls (n = 217). Data were analyzed using principal component analysis followed by machine learning and support vector machine modeling.

RESULTS

We identified 172 immunogenic epitopes of the tTG-DGP complex. We found significantly increased immune reactivity against these epitopes vs controls. In the both cohort, the set of neoepitopes derived from the tTG-DGP complex identified patients with CeD with 99% sensitivity and 100% specificity. Serum samples from patients with untreated CeD had the greatest mean antibody-binding intensity against the tTG-DGP complex (32.5 ± 16.4). The average antibody-binding intensity was significantly higher in serum from patients with treated but unhealed CeD mucosa (15.1 ± 7.5) than in patients with treated and healed CeD mucosa (5.5 ± 3.4) (P < .001). The assay identified patients with mucosa healing status with 84% sensitivity and 95% specificity.

CONCLUSIONS

We identified immunogenic epitopes of the tTG-DGP complex, and found that an assay to measure the immune response to epitopes accurately identified patients with CeD, as well as patients with mucosal healing. This biomarker assay might be used in detection and monitoring of patients with CeD.

Coeliac disease: factors affecting the transition and a practical tool for the transition to adult healthcare

Background

As of now, no established model for the transition from childhood to adulthood in coeliac disease exists. We aim to describe the dietary compliance and the quality of life of a population of young coeliac disease patients around transition age and to develop a practical tool (TRANSIT-CeD disk) which can be used during the transition process effectively to transmit young adults to the adult healthcare giver.

Methods

We consecutively recruited all coeliac disease patients with a paediatric diagnosis (≤16 years) and aged between 9 and 20 years at the time of the study. The patients were asked to answer some questions concerning their adherence to a gluten-free diet, knowledge about coeliac disease, relationship with healthcare givers and quality of life.

Results

We included 58 subjects, mean age 14.5 ± 3.6 years, of which 62% were girls/young women. We observed that dietary compliance was independently and positively related to age at diagnosis and coeliac disease knowledge, while quality of life was only independently and positively related to coeliac disease knowledge.

Conclusion

A good coeliac disease knowledge is positively related to dietary compliance and quality of life. With the help of the TRANSIT-CeD disk we proposed, paediatricians and adult gastroenterologists can follow the patients during the transition and identify some points to work on.

Creation of Experience-based Celiac Benchmarks: The First Step in Pretransition Self-management Assessment

OBJECTIVES

Transition planning for children with chronic disease includes the development of independence in many self-management tasks. Conditions that depend on diet have distinct skill sets not well assessed by the traditional transition-readiness tools. There has been literature that describes age-appropriate skill acquisition for diabetes and food allergy patients. There are, however, no age-appropriate benchmarks established for celiac disease (CD).

METHODS

CD experts (including physician, nurse, dietician, social worker, patient, and parent) created a list of celiac-related tasks, which formed the basis of the survey. Patients with CD, and their parents, were recruited from outpatient celiac clinic and support groups, and invited to report the age each task was mastered.

RESULTS

Respondents included 204 patients and 155 parents. Mean age was 12 years (standard deviation 4.6) with average of 4 years since diagnosis. The earliest tasks were mastered by a median age of 8 years, such as recognizing GF as gluten-free, eating safely in a shared space and recognizing basic unsafe foods. Describing the effects of eating gluten or explaining CD to a friend or stranger occurred around age 10. Asking about gluten-free preparation in a restaurant, and identifying gluten-free medications or vitamins was mastered around age 12, whereas tasks involved with safe domestic travel or assessing risk in a job environment occurred between 14 and 16. The interquartile range was about 4 years for each question. No significant difference seen between patient and parent reports.

CONCLUSIONS

This novel patient-centered celiac skill list may improve anticipatory guidance and accelerate self-management skills.

The Health Care Transition of Youth With Liver Disease Into the Adult Health System: Position Paper From ESPGHAN and EASL

BACKGROUND

Medical advances have dramatically improved the long-term prognosis of children and adolescents with once-fatal hepatobiliary diseases. However, there is no generally accepted optimal pathway of care for the transition from paediatric care to the adult health system.

AIM

The purpose of this position paper is to propose a transition process for young people with paediatric onset hepatobiliary diseases from child-centred to adult-centred healthcare services.

METHODS

Seventeen ESPGHAN/EASL physicians from 13 countries (Austria, Belgium, France, Germany, Hungary, Italy, the Netherlands, Norway, Poland, Spain, Sweden, Switzerland, and United Kingdom) formulated and answered questions after examining the currently published literature on transition from childhood to adulthood. PubMed and Google Scholar were systematically searched between 1980 and January 2018. Quality of evidence was assessed by the Grading of Recommendation Assessment, Development and Evaluation (GRADE) system. Expert opinions were used to support recommendations whenever the evidence was graded weak. All authors voted on each recommendation, using the nominal voting technique.

RESULTS

We reviewed the literature regarding the optimal timing for the initiation of the transition process and the transfer of the patient to adult services, principal documents, transition multi-professional team components, main barriers, and goals of the general transition process. A transition plan based on available evidence was agreed focusing on the individual young people's readiness and on coordinated teamwork, with transition monitoring continuing until the first year of adult services.We further agreed on selected features of transitioning processes inherent to the most frequent paediatric-onset hepatobiliary diseases. The discussion highlights specific clinical issues that will probably present to adult gastrointestinal specialists and that should be considered, according to published evidence, in the long-term tracking of patients.

CONCLUSIONS

Transfer of medical care of individuals with paediatric onset hepatobiliary chronic diseases to adult facilities is a complex task requiring multiple involvements of patients and both paediatric and adult care providers.

Contributions of HLA haplotypes, IL8 level and Toxoplasma gondii infection in defining celiac disease's phenotypes

BACKGROUND

It is not clear why some patients with coeliac disease (CD) present with severe symptoms and small intestinal mucosal damages while others present with milder symptoms and no frank enteropathy. There is no study to assess the associated factors with mild/severe symptoms and enteropathy. The terminologies like latent, silent and potential are difficult to use and are unrepresentative. In the present study we describe coeliac disease's phenotypes based on HLA haplotypes, IL8 production and past infection with Toxoplasma gondii (T. gondii) infection.

METHODS

In this case-control study, sera originating from 150 healthy subjects and 150 patients diagnosed with CD during the years 2013-14 were analyzed for the presence of antibodies specific T. gondii of the IgG and IgM subclasses. The level of IL8 were measured and HLA-DQ2 and HLA-DQ8 alleles were genotyped. The correlation between these parameters and the damages in intestinal mucosal were assessed using an accepted histopathological classification.

RESULTS

High levels of IgG antibodies against T. gondii were found in the sera of control group compared to the CD group (52.6% vs. 39.4%, P = 0.02). Mean serum levels of IL8 was significantly higher in CD patients compared with control (P ≤ 0.05). By comparing the level of anti- T. gondii IgG and mucosal damage in celiac disease, we found a significant relationship between the severity of mucosal damages and anti- T. gondii IgG level (P = 0.02). No correlation was detected between Toxoplasma gondii infection and types of HLA (P > 0.05). However, patients with severely abnormal histology carried HLA-DQ2 risk alleles (92 patients (61%)) more often than the controls and those with mild histological abnormalities.

CONCLUSIONS

CD patients with severe histological changes had more often Toxoplasma gondii infection than those affected with mild histological features. This suggests that CD's phenotypes are correlated to additional factors like infections and to particular HLA DQ2 alleles that may need additional investigations and potentially will require additional treatment.

Coeliac disease

Coeliac disease occurs in about 1% of people in most populations. Diagnosis rates are increasing, and this seems to be due to a true rise in incidence rather than increased awareness and detection. Coeliac disease develops in genetically susceptible individuals who, in response to unknown environmental factors, develop an immune response that is subsequently triggered by the ingestion of gluten. The disease has many clinical manifestations, ranging from severe malabsorption to minimally symptomatic or non-symptomatic presentations. Diagnosis requires the presence of duodenal villous atrophy, and most patients have circulating antibodies against tissue transglutaminase; in children, European guidelines allow a diagnosis without a duodenal biopsy provided that strict symptomatic and serological criteria are met. Although a gluten-free diet is an effective treatment in most individuals, a substantial minority develop persistent or recurrent symptoms. Difficulties adhering to a gluten-free diet have led to the development of non-dietary therapies, several of which are undergoing trials in human beings.

Coeliac disease: to biopsy or not?

Coeliac disease is increasingly recognized as a global problem in both children and adults. Traditionally, the findings of characteristic changes of villous atrophy and increased intraepithelial lymphocytosis identified in duodenal biopsy samples taken during upper gastrointestinal endoscopy have been required for diagnosis. Although biopsies remain advised as necessary for the diagnosis of coeliac disease in adults, European guidelines for children provide a biopsy-sparing diagnostic pathway. This approach has been enabled by the high specificity and sensitivity of serological testing. However, these guidelines are not universally accepted. In this Perspective, we discuss the pros and cons of a biopsy-avoiding pathway for the diagnosis of coeliac disease, especially in this current era of the call for more biopsies, even from the duodenal bulb, in the diagnosis of coeliac disease. In addition, a contrast between paediatric and adult guidelines is presented.

Development and Validation of the Celiac Disease-Children's Activities Report (CD-Chart) for Promoting Self-Management among Children and Adolescents

Adherence to a restrictive gluten-free diet is the only known treatment for celiac disease (CD). Children and adolescents with CD encounter challenges while managing the diet in daily activities. Understanding their participation characteristics is lacking. The aim was to describe the development and validation process of the Celiac Disease-Children's Activities Report (CD-Chart). The final CD-Chart includes nine food-related activities that are measured by six core dimensions: frequency, preference, preparation, involvement, help, and self-determination. Participants were 126 children (8-11 years) and adolescents (12-18 years) with CD, and 30 healthy matched controls. Factor analysis was performed and psychometric properties were measured. Content and face validity was established and the CD-Chart showed adequate internal consistency as measured by the preference dimension (α = 0.81). Factor analysis revealed two distinct factors, social environment and close family environment. Construct validity demonstrated that the group with CD required significantly more pre-preparation for food-related activities than controls, (t(38) = 76.25, p < 0.001) and further differences as well as similarities were found between groups. Primary results indicate that the CD-Chart may serve as a practical tool for acquiring information about participation characteristics in food-related activities, strengths and challenges of children and adolescents with CD, to promote self-management, diet adherence, and well-being.

Activities, Participation and Quality of Life Concepts in Children and Adolescents with Celiac Disease: A Scoping Review

Celiac disease (CD) is a food-related chronic condition and adherence to a strict gluten-free diet is the only available treatment. Adherence to the restrictive diet is challenging among children, especially adolescents. The aim was to describe existing knowledge about food-related activities, participation, and quality of life in daily life among children and adolescents with CD and to illuminate gaps in knowledge. The scoping review methodology was applied and literature searches were conducted in electronic databases. Twenty-three articles met the inclusion criteria. Food-related activities were identified, classified, and coded under the International Classification of Functioning, Disability, and Health adapted for children and youth (ICF-CY) concepts of activities and participation. A wide variety of study populations, objectives, methods, and tools involving 55 different food-related activities were found. Incorporation of the ICF-CY concepts and quality of life captures new insights into everyday challenges. Reviewing the CD literature using this different lens reveals areas yet to receive sufficient attention. Further research can deepen the understanding of daily functioning of children with CD and the underlying skills required to participate in daily food-related activities while adhering to the diet. This can lead to the development of standardized disease-specific assessment tools and suitable intervention programs.

Coeliac disease: review of diagnosis and management

Coeliac disease is an immune-mediated systemic disease triggered by exposure to gluten, and manifested by small intestinal enteropathy and gastrointestinal and extra-intestinal symptoms. Recent guidelines recommend a concerted use of clear definitions of the disease. In Australia, the most recent estimated prevalence is 1.2% in adult men (1:86) and 1.9% in adult women (1:52). Active case finding is appropriate to diagnose coeliac disease in high risk groups. Diagnosis of coeliac disease is important to prevent nutritional deficiency and long term risk of gastrointestinal malignancy. The diagnosis of coeliac disease depends on clinico-pathological correlation: history, presence of antitransglutaminase antibodies, and characteristic histological features on duodenal biopsy (when the patient is on a gluten-containing diet). Human leucocyte antigen class II haplotypes DQ2 or DQ8 are found in nearly all patients with coeliac disease, but are highly prevalent in the general population at large (56% in Australia) and testing can only exclude coeliac disease for individuals with non-permissive haplotypes. Adhering to a gluten free diet allows duodenal mucosal healing and alleviates symptoms. Patients should be followed up with a yearly review of dietary adherence and a health check. Non-coeliac gluten or wheat protein sensitivity is a syndrome characterised by both gastrointestinal and extra-intestinal symptoms related to the ingestion of gluten and possibly other wheat proteins in people who do not have coeliac disease or wheat allergy recognised by diagnostic tests.

Increased risk of herpes zoster in patients with coeliac disease - nationwide cohort study

BACKGROUND AND AIMS

Clinical experience suggests that patients with coeliac disease (CD) are more prone to develop herpes zoster (HZ), but robust studies are lacking.

METHODS

We identified 29,064 patients with CD 1969-2008 using biopsy report data from Sweden's 28 pathology departments. CD was equalled to villous atrophy (Marsh histopathology grade III). Each patient was matched on age, sex, calendar year and county of residence to up to five reference individuals ( n=144,342) from the general population. We then used Cox regression to estimate hazard ratios (HRs) for future HZ (defined as having a hospital-based inpatient or outpatient record of this diagnosis in the Swedish Patient Register).

RESULTS

During follow-up, 154 (0.53%) individuals with CD and 499 (0.35%) reference individuals developed HZ. Among individuals aged ≥60 years, 1.06% of CD individuals and 0.85% of reference individuals had a lifetime record of HZ. Overall, CD was associated with a 1.62-fold increased risk of HZ (95% CI=1.35-1.95), and was seen also when we considered comorbidity with lymphoproliferative disease, systemic lupus erythematosus, type 1 diabetes, thyroid disease, rheumatoid disease and excluded individuals with a record of dermatitis herpetiformis. The increased risk remained significant after more than five years of follow-up (1.46; 1.16-1.84) Conclusions: CD is associated with HZ, the increased relative risk persists over time from celiac diagnosis but the absolute risk is small.

UK guideline on transition of adolescent and young persons with chronic digestive diseases from paediatric to adult care

The risks of poor transition include delayed and inappropriate transfer that can result in disengagement with healthcare. Structured transition care can improve control of chronic digestive diseases and long-term health-related outcomes. These are the first nationally developed guidelines on the transition of adolescent and young persons (AYP) with chronic digestive diseases from paediatric to adult care. They were commissioned by the Clinical Services and Standards Committee of the British Society of Gastroenterology under the auspices of the Adolescent and Young Persons (A&YP) Section. Electronic searches for English-language articles were performed with keywords relating to digestive system diseases and transition to adult care in the Medline (via Ovid), PsycInfo (via Ovid), Web of Science and CINAHL databases for studies published from 1980 to September 2014. The quality of evidence and grading of recommendations was appraised using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The limited number of studies in gastroenterology and hepatology required the addition of relevant studies from other chronic diseases to be included.These guidelines deal specifically with the transition of AYP living with a diagnosis of chronic digestive disease and/or liver disease from paediatric to adult healthcare under the following headings;1. Patient populations involved in AYP transition2. Risks of failing transition or poor transition3. Models of AYP transition4. Patient and carer/parent perspective in AYP transition5. Surgical perspective.

The Transition of the Gastrointestinal Patient from Pediatric to Adult Care

Transition is the long process of developing independent self-management skills whereas transfer is the actual move from pediatric to adult-centered provider. Structured anticipated transition works best with timelines of tasks to master and discussion of the stylistic differences between pediatric and adult practices. Disease-specific issues need to be addressed, such as earlier timelines for diet-based therapies, parental support for critical illnesses, and differences in therapeutic strategies.

Challenges in gluten-free diet in coeliac disease: Prague consensus

BACKGROUND

New treatments in coeliac disease are being vigorously pursued to either replace or facilitate the difficult-tofollow gluten-free diet.

DESIGN

The present review intends to summarise the challenges in gluten-free diet adherence during the transitional period, as reflected in the last Prague consensus, published in 2016.

RESULTS

The honourable panel members recommended that dietary adherence and the consequences of nonadherence represent key components for discussion in the transitional period setting.

CONCLUSIONS

There are numerous difficulties in adhering to gluten withdrawal, but the transition period from adolescence to young adulthood is considered a fragile and high-risk period for intentional and unintentional gluten intake.
