Abstract
Background Celiac disease (CD) is an immune-mediated enteropathy that has been associated with other immune-related gastrointestinal disorders, such as eosinophilic esophagitis (EoE) and lymphocytic gastritis (LG). To our knowledge, this is the first study in Saudi Arabia that has described such an association. Aim To evaluate the prevalence of EoE and LG in children and adolescents with CD. Methods This was a retrospective cross-sectional study of all pediatric patients (aged 0-18 years) with CD following up at King Abdulaziz University Hospital, between January, 2014, and December, 2021. The study examined clinical, demographic, endoscopic, and histopathological data. Results Seventy-five patients with CD were included in the analysis. The median age was 12 years (range, 2-18 years). Male constituted 54.7% of the overall cohort (n = 41). The most common clinical symptoms were short stature (54.7%), weight loss (34.7%), abdominal pain (33.3%), abdominal distension (29.3%), anorexia (29.3%), diarrhea (24%), and vomiting (21.3%). The esophageal biopsy results reported were basal cell hyperplasia in 24 patients (32.9%), esophageal eosinophilia in 23 patients (31.5%), and EoE in 3 patients (4.1%). The gastric biopsy results were normal in 40 patients (53.3%). The most common abnormality was chronic inactive gastritis with no Helicobacter pylori (HP) infection (16%). LG was found in 3 patients (4%). Conclusions The prevalence of EoE in this cohort of patients with CD was lower than the prevalence recorded in a number of other studies. Further studies are needed to determine the effects of a gluten-free diet (GFD) on EOE and LG.

Abstract
BACKGROUND Autoimmune diseases (AIDs) share a common molecular etiology and often present overlapping clinical presentations. Thus, this study aims to explore the complex molecular basis of AID by whole exome sequencing and computational biology analysis. METHODS Molecular screening of the consanguineous AID family and the computational biology characterization of the potential variants were performed. The potential variants were searched against the exome data of 100 healthy individuals and 30 celiac disease patients. RESULT A complex inheritance pattern of PAK2 (V43A), TAP2 (F468Y), and PLCL1 (V473I) genetic variants was observed in the three probands of the AID family. The PAK2 variant (V43A) is a novel one, but TAP2 (F468Y) and PLCL1 (V473I) variants are extremely rare in local Arab (SGHP and GME) and global (gnomAD) databases. All these variants were localized in functional domains, except for the PAK2 variant (V43A) and were predicted to alter the structural (secondary structure elements, folding, active site confirmation, stability, and solvent accessibility) and functional (gene expression) features. Therefore, it is reasonable to postulate that the dysregulation of PAK2, TAP2, and PLCL1 genes is likely to elicit autoimmune reactions by altering antigen processing and presentation, T cell receptor signaling, and immunodeficiency pathways. CONCLUSION Our findings highlight the importance of exploring the alternate inheritance patterns in families presenting complex autoimmune diseases, where classical genetic models often fail to explain their molecular basis. These findings may have potential implications for developing personalized therapies for complex disease patients.

TagSNP approach for HLA risk allele genotyping of Saudi celiac disease patients: effectiveness and pitfalls. Biosci Rep 2021; 41:BSR20210509.

Abstract
BACKGROUND Celiac disease (CD) is a genetically complex autoimmune disease which is triggered by dietary gluten. Human leukocyte antigen (HLA) class II genes are known to act as high-risk markers for CD, where >95% of CD patients carry (HLA), DQ2 and/or DQ8 alleles. Therefore, the present study was conducted to investigate the distribution of HLA haplotypes among Saudi CD patients and healthy controls by using the tag single nucleotide polymorphisms (SNP). METHODS HLA-tag SNPs showing strong linkage value (r2>0.99) were used to predict the HLA DQ2 and DQ8 genotypes in 101 Saudi CD patients and in 103 healthy controls by using real-time polymerase chain reaction technique. Genotype calls were further validated by Sanger sequencing method. RESULTS A total of 63.7% of CD cases and of 60.2% of controls were predicted to carry HLA-DQ2 and DQ8 heterodimers, either in the homozygous or heterozygous states. The prevalence of DQ8 in our CD patients was predicted to be higher than the patients from other ethnic populations (35.6%). More than 32% of the CD patients were found to be non-carriers of HLA risk haplotypes as predicted by the tag SNPs. CONCLUSION The present study highlights that the Caucasian specific HLA-tag SNPs would be of limited value to accurately predict CD specific HLA haplotypes in Saudi population, when compared with the Caucasian groups. Prediction of risk haplotypes by tag SNPs in ethnic groups is a good alternate approach as long as the tag SNPs were identified from the local population genetic variant databases.

Abstract
BACKGROUND AND STUDY AIMS Autoimmune liver diseases (ALDs) are a clinico-pathologic spectrum of disorders that share some similarities. They are formally classified as autoimmune hepatitis (AIH), isolated autoimmune sclerosing cholangitis (ASC), and the overlap syndrome of these. We describe the clinical, biochemical, and outcomes data of a cohort of autoimmune ALDs patients in a tertiary care centre. PATIENTS AND METHODS This is a cross-sectional study conducted at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Data were collected in 2007-2018. All cases were 18 years old or younger at the time of diagnosis. The data collection comprised clinical, laboratory, imaging, treatment, and longitudinal follow-up data. RESULTS Twenty-five patients were identified; 14 (56%) were females. Twenty-one patients (84%) had AIH-1,1 patient (4%) had AIH-2, and 3 patients (12%) had autoimmune sclerosing cholangitis (ASC). An insidious course was found in 21 (84%) cases. Acute hepatitis and fulminant hepatic failure was found to be very rare. Eight cases (32%) had cirrhosis at diagnosis. A total of 20 cases (80%) had complete remission following therapy. The median follow-up period was 45 months. There was no mortality, and only one patient was referred for transplant. Thus, the transplant-free survival was 96%. CONCLUSIONS Our study showed predominance of AIH-1 over AIH-2. Response to treatment in our cohort was found to be similar to the results found in some other key studies. Prognosis and transplant-free survival is better than many published paediatric studies.
