Although the incidence of pediatric IBD in Saudi Arabian children is lower than suggested in the Western literature, there is a significantly increasing trend over time. However, decreased trend in the younger age group over time is identified. Prospective studies will be important to identify the risk factors for IBD in different age groups.

PurposeTo describe the clinical characteristics of celiac disease (CD) among Saudi children and to determine the adherence rate to gluten free diet (GFD) and its determinant factors among them.MethodsA cross-sectional study was conducted, in which all the families registered in the Saudi Celiac Patients Support Group were sent an online survey. Only families with children 18 years of age and younger with biopsy-confirmed CD were included.ResultsThe median age of the 113 included children was 9.9 years, the median age at symptom onset was 5.5 years and the median age at diagnosis was 7 years, the median time between the presentation and the final diagnosis was 1 year. Sixty two of the involved children were females. Ninety two percent of the patients were symptomatic at the diagnosis while eight percent were asymptomatic. The commonest presenting symptoms included: chronic abdominal pain (59.3%), poor weight gain (54%), abdominal distention, gases, bloating (46.1%) and chronic diarrhea (41.6%). Sixty percent of the involved children were reported to be strictly adherent to GFD. Younger age at diagnosis and shorter duration since the diagnosis were associated with a better adherence rate.ConclusionCD has similar clinical presentations among Saudi children compared to other parts of the ward; however, the adherence to GFD is relatively poor. Younger age at diagnosis and shorter duration since the diagnosis were associated with a better adherence rate.

PurposeTo determine the socio-economic impact of gluten free diet (GFD) on Saudi children and their families.MethodsA cross-sectional study was conducted in which an online questionnaire was sent to all families registered in the Saudi celiac patients support group. We included only children (age 18 years of age and younger) with biopsy-confirmed celiac disease (CD).ResultsA total of 113 children were included in the final analysis, the median age was 9.9 years; 62.8% were females. One hundred (88.5%) of the participating families reported that GFD food was not easily available in their areas, 17% of them reported that it was not available at all in their area. One hundred and six (93.8%) reported that the price of GFD food was very expensive and 70 (61.9%) families that the diet was heavily affecting their family budget. Significant social difficulties were reported among the participating families and their children including interference with the child's interaction with other children (49.6%), the families' ability to attend social gatherings (60.2%), the families' ability to eat in restaurants (73.5%), and the families' ability to travel (58.4%).ConclusionThere is significant negative socio-economic impact of GFD on children with CD & their families. Health care providers should be aware of these psycho-social difficulties and be well trained to provide a proper education and psychological support for these patients and their families.

Celiac disease (CD), a gluten intolerance disorder, was implicated to have 57 genetic susceptibility loci for Europeans but not for culturally and geographically distinct ethnic populations like Saudi Arabian CD patients. Therefore, we genotyped Saudi CD patients and healthy controls for three polymorphisms, that is, Phe196Ser in IRAK1, Trp262Arg in SH2B3, and Met518Thr in MMEL1 genes. Single locus analysis identified that carriers of the 518 Thr/Thr (MMEL1) genotype conferred a 1.6-fold increased disease risk compared to the noncarriers (OR = 2.6; 95% CI: 1.22–5.54; P < 0.01). This significance persisted even under allelic (OR = 1.55; 95% CI: 1.05–2.28; P = 0.02) and additive (OR = 0.35; 95% CI: 0.17–0.71; P = 0.03) genetic models. However, frequencies for Trp262Arg (SH2B3) and Phe196Ser (IRAK1) polymorphisms were not significantly different between patients and controls. The overall best MDR model included Met518Thr and Trp262Arg polymorphisms, with a maximal testing accuracy of 64.1% and a maximal cross-validation consistency of 10 out of 10 (P = 0.0156). Allelic distribution of the 518 Thr/Thr polymorphism in MMEL1 primarily suggests its independent and synergistic contribution towards CD susceptibility among Saudi patients. Lack of significant association of IRAK and SH2B3 gene polymorphisms in Saudi patients but their association in European groups suggests the genetic heterogeneity of CD.
