Genetic and dental study of patients with celiac disease

Coeliac disease and its implications on the oral health of children: A systematic review

AIM

Apart from various typical gastrointestinal symptoms, coeliac disease may have its clinical manifestations in the oral cavity which is the entrance of the gastrointestinal tract.

METHODS

A systematic review of literature was performed using the following databases: Medline, Scopus, EBSCOhost and Cochrane Library for Systematic Review.

INCLUSION CRITERIA

observational or experimental original studies published in English with full text available between January 2000 and December 2022, regarding children and adolescents under the age of 20. Risk of bias was determined with the use of Risk Of Bias In Non-randomised Studies of Exposure.

RESULTS

Thirty-four studies were included in the review. The analysis confirmed a higher prevalence of numerous oral manifestations in coeliac disease concerning both hard and soft tissues. Our study found the prevalence of dental enamel defects to be at the level of 17.9%-83.5% (P value <0.047) and recurrent aphthous stomatitis of 8.3%-69% (P value <0.039).

CONCLUSION

Oral manifestations may precede gastrointestinal symptoms. Patients presenting such manifestations should be screened for coeliac disease. The cooperation of gastroenterologists and dentists could lead to an increased detectability of coeliac disease.

Oral and dental manifestations of celiac disease in children: a case-control study

Background

Celiac disease (CD) is an immune-mediated enteropathy. CD may also involve complications with the oral cavity, which can result in various dental and oral pathologies. There are currently a limited number of studies on the oral manifestation of CD. This study aims to compare the oral manifestations of children with CD against healthy controls in Saudi Arabia.

Materials and methods

This study includes 208 children aged 6–14 years, distributed equally into CD patients and healthy controls. A parent completed and validated the interview questionnaire, which included the child's personal information and medical history. A dental examination was undertaken to measure possible recurrent aphthous stomatitis (RAS), dental enamel defects (DEDs), dental caries experience, and dental malocclusion. Data were analyzed using descriptive statistics and bivariate and multivariate analysis.

Results

Two hundred and eight participants were included (104 CD patients and 104 controls). The mean age for CD patients was 10.67 ± 2.39 years and 10.69 ± 2.36 for the healthy controls. CD children had more RAS than controls (42.3% vs. 15.4%, P < 0.001) (OR = 4.03, 95% CI = 2.09–7.81) and more DEDs than healthy controls (70.2% vs. 34.6%, P < 0.001) (OR = 4.45, 95% CI = 2.48–7.97). No significant difference was found in the frequency of malocclusion between cases and controls.

Conclusion

Saudi Arabian children with CD had a greater number of clinical findings of RAS and DEDs than healthy controls. Pediatric dentists should consider the possibility of CD in child patients presenting with RAS or DEDs.

Clinical manifestations of gastrointestinal diseases in the oral cavity

Aim

In this review, several gastrointestinal diseases that dentists may encounter in practice are highlighted and discussed.

Materials and methods

Using MEDLINE (PubMed), a comprehensive review of gastrointestinal diseases and their oral cavity manifestations was performed.

Results

Many gastrointestinal diseases present with oral symptoms that are detectable by dentists and dental hygienists. Often, oral manifestations of the disease may appear before systemic signs and symptoms. Managing patients with these conditions requires dentists to adjust their treatment and/or involve other health professionals.

Conclusion

Care must be taken when providing periodontal therapy or dental implants to patients suffering gastrointestinal diseases who are at high risk of bleeding, infection, or malnutrition, for example. Also, pharmacological therapy for these patients may need to be customized.

Clinical evaluation of dental enamel defects and oral findings in coeliac children

Purpose

To examine dental hard and soft tissue changes of coeliac children in order to increase the awareness of the pediatric dentists in prediagnosis of especially undiagnosed coeliac disease.

Materials and methods

Sixty children, 28 (46.7%) boys and 32 (53.3%) girls whose ages were between 6 to 16 years were included in the present study. Thirty children who had undergone endoscopy and diagnosed with the coeliac disease in the Şişli Hamidiye Etfal Hospital, İstanbul, Turkey, formed the study group. Also, thirty children clinically suspected of having the coeliac disease with the same gastrointestinal complaints had undergone endoscopy and proven not coeliac were chosen as the control group. Oral examination involved assessment of dentition and specific and unspecific dental enamel defects. Also, soft tissue lesions, clinical delay of the dental eruption, salivary flow rate, pH, and buffering capacity were examined.

Results

Twenty coeliac patients had enamel defects, however none in the control subjects. In the coeliac group, all enamel defects were diagnosed in permanent teeth and as specific in all children. Grade I dental enamel defects found mainly in the incisors. The clinical delayed eruption was observed in 10 (33.3%) of 30 coeliac children and none of the children in the control group. While the level of DMFT/S numbers and stimulated salivary flow rate were found significantly lower in the coeliac group, pH was found significantly higher.

Conclusion

Oral cavity may be involved in coeliac disease and pediatric dentists can play an important role in the early diagnosis of the coeliac disease.

Association between developmental defects of enamel and celiac disease: A meta-analysis

OBJECTIVES

Studies have observed the presence of extra-intestinal manifestations of celiac disease (CD), including involvement of the oral cavity, such that developmental defects of enamel (DDE) occur. Thus, the aim of this review was to access the polled prevalence of DDE in individuals with CD, and to establish the strength of the association between these two variables.

METHODS

To carry out the systematic review, four electronic databases and the Grey Literature were searched, complemented by a manual search of reference lists within the selected articles. Two pairs of independent reviewers selected the articles, and perform the data extractions and bias risk assessment Studies evaluating the presence of DDE in individuals with CD as well as in healthy individuals and which performed the DDE diagnosis by direct visualization of tooth enamel changes and the CD diagnosis were included. Meta-analyses were performed using the software R.

RESULTS

Of 557 studies, 45 were selected for review, encompassing 2840 patients. The prevalence of DDE in people with CD was 50% (95% CI 0.44-0.57, I² = 88%). In a general analysis, it was observed that patients with CD had a significantly higher prevalence of enamel defects compared to healthy people (RR: 2.31, 95% CI: 1.71-3.12, I² = 98%). Only developmental defects of enamel diagnosed using Aine's method were associated with the disease (RR: 3.30, 95% CI 2.39-4.56, I² = 75%). In a sensitivity analysis involving the deciduous, mixed and permanent dentitions, only individuals with deciduous dentition were observed to have association with the disease (RR: 2.34, 95% CI 1.25-4.39, I² = 39%).

CONCLUSIONS

Patients with enamel developmental defects should be screened for the possibility of their having celiac disease.

Spectrum of Celiac disease in Paediatric population: Experience of Tertiary Care Center from Pakistan

Objective:

To determine clinical features and relevant laboratory investigations of patient with celiac disease (CD) and comparing classical celiac disease (CCD) with Non-diarrheal celiac disease (NDCD).

Methods:

This is a five years retrospective study conducted at The Aga Khan University Hospital Karachi, Pakistan from January 2010 to December 2015, enrolling children from one year to 15 years of either gender diagnosed as celiac disease in accordance with revised ESPGHAN criteria. Biopsy samples with grade 2 or more on Modified Marsh Classification were considered as consistent with celiac disease. Celiac patients were categorized into Classical celiac disease (with Chronic Diarrhea) and non-diarrheal celiac disease (Atypical celiac) and their clinical features and relevant laboratory investigations were documented.

Results:

Total 66 patients were selected with celiac disease according to inclusion criteria, 39 (59.09%) patients were labeled as CCD and 27 (40.91%) patients were labeled as NDCD. Marsh grading 3a and above were more marked in CCD as compared to NDCD. Mean titer for Tissue transglutaminase antibodies (TTG) were higher in CCD group in comparison to NDCD group. In CCD, the most common clinical presentations were abdominal distension whereas in NDCD, the most remarkable features were recurrent abdominal pain (62.9%). Frequency of failure to thrive is significantly high in CCD (82.05%) but patients merely with short stature were more common in NDCD (33.3%). Refractory anemia was present in 66.6% patients in NDCD group and 41.1% patients in CCD group. 74.3% patients in CCD group were vitamin D deficient whereas 85% patient had vitamin D deficiency in NDCD group (p= 0.03).

Conclusion:

NDCD is not uncommon in our population. Recurrent abdominal pain, failure to thrive or patients only with short stature and refractory anemia are prominent features in NCDC group whereas abdominal distension, failure to thrive and recurrent abdominal pain were noticeable features in CCD. High grade histopathology and raised antibodies titer is hallmark of CCD. Vitamin D deficiency is almost equally present in both groups.

Celiac disease-related osteopathy among Saudi celiac patients: Are we adherent to recommendations?

BACKGROUND/AIMS

There are no reports from Saudi Arabia documenting the picture of osteopathy in celiac disease (CD) and the adherence of physicians to the guidelines and recommendations to screen for bone disease. We conducted this study to document the prevalence of CD-related osteopathy and the Saudi physicians' adherence to the screening recommendations.

PATIENTS AND METHODS

We identified the biopsy proven CD cases diagnosed between 2003 and 2012. In addition to demographic data, we collected laboratory (serum calcium, phosphate, alkaline phosphatase, 25-dihydroxy vitamin D, and parathyroid hormone levels) and imaging [Dual-energy X-ray absorptiometry (DEXA)] data. Vitamin D levels of <50 nmol/L and 50-<75 nmol/L defined deficiency and insufficiency, respectively. T score (of lumbar spine and femoral neck) of ≤-2.5 defined osteoporosis and a score of ≤-1 and >-2.5 defined osteopenia.

RESULTS

We identified 80 children and 128 adults with CD. Only 42% of children and 67% of adults had their serum vitamin D level measured. DEXA was ordered in 7% of children and 36% of adults. Vitamin D deficiency was widely prevalent and significantly higher in adults (95.3%) than children (76.3%). Low bone mass density (BMD) in adults was 86.9% (45.6% with osteopenia and 41.3% with osteoporosis).

CONCLUSIONS

We document low adherence of physicians to recommended guidelines to recommendations to screen for osteopathy in CD. Vitamin D deficiency and low BMD are highly prevalent among Saudi CD patients. This may be a reflection of the low vitamin D stores in the Saudi general population.

Consanguinity and inflammatory bowel diseases: is there a relation?

OBJECTIVE

The aim of the present study was to investigate the relation between consanguinity and inflammatory bowel diseases (IBD).

METHODS

Review of the medical records of children with a final diagnosis of IBD to determine age, sex, and type of IBD, supplemented by information on consanguinity and family history (FH) of IBD in relatives. There were 138 children, ages 1.4 to 19.3 years, and 50% were girls.

RESULTS

The prevalence of consanguinity was 50%, 53%, 39% and 60% in IBD, Crohn disease (CD), ulcerative colitis (UC), and controls, respectively. There was a significantly higher prevalence of consanguinity in controls than in patients with IBD and UC (P = 0.02 and 0.026, respectively), whereas the difference between CD patients and controls was not significant (P = 0.20). The prevalence of first cousin consanguinity was 71%, 73.2%, 61.5% and 70.5% in patients with IBD, CD, UC, and controls, respectively, indicating no significant difference between these conditions and controls (P = 0.95, P = 0.78, P = 0.33, respectively). There was no significant difference in the prevalence of consanguinity in the parents of children with or without a FH of either CD (P = 0.89) or UC (P = 0.32).

CONCLUSIONS

There is no significant relation between parental consanguinity and IBD in this population, especially when there is no FH of disease, suggesting reduced genetic susceptibility; however, further studies including larger sample size and details of FH of consanguinity and IBD in multiple generations are needed for further definitions of the role of consanguinity.
