Abstract
OBJECTIVES Recurrent aphthous ulcer (RAU) is a prevalent oral mucosal disease, affecting around 20% of the global population. It can greatly impair the quality of life for affected individuals. However, the exact etiology of RAU remains unknown. SUBJECTS AND METHODS 16S rRNA sequencing (16S rRNA-seq) and non-targeted liquid chromatography-mass spectrometry (LC-MS) were employed to investigate the salivary microbiota and metabolic phenotype between RAU patients (N = 61) and healthy controls (HCs) (N = 105). RESULTS Findings from 16S rRNA -seq indicated reduced oral microbial diversity in RAU patients compared to HCs, but increased interactions. Clinical variables did not show any significant association with the overall diversity of oral microbiota in RAU patients. However, significant correlations were observed between specific microorganisms and clinical variables. LC-MS results revealed dysregulation of amino acid, lipid, nucleotide, and caffeine metabolism in RAU patients. Furthermore, correlation analysis of 16S rRNA-seq and LC-MS data revealed a significant association between salivary microbiota and metabolites in RAU patients. CONCLUSIONS Our study revealed notable differences in salivary microbiota and metabolic profiles between RAU patients and HCs, indicating a strong link between oral microbiota dysbiosis, metabolic disturbances, and the onset and progression of RAU.

Abstract
Oral mucosal disease (OMD), which is also called soft tissue oral disease, is described as a series of disorders or conditions affecting the mucosa and soft tissue in the oral cavity. Its etiology is unclear, but emerging evidence has implicated the influence of the composition of the oral mucosa and saliva-resident microbiota. In turn, this dysbiosis effects the immune response balance and epithelial barrier function, followed by the occurrence and progression of OMD. In addition, oral microbial dysbiosis is diverse in different types of diseases and different disease progressions, suggesting that key causal pathogens may exist in various oral pathologies. This narrative literature review primarily discusses the most recent findings focusing on how microbial dysbiosis communicates with mucosal adaptive immune cells and the epithelial barrier in the context of five representative OMDs, including oral candidiasis (OC), oral lichen planus (OLP), recurrent aphthous ulcer (RAU), oral leukoplakia (OLK), and oral squamous cell carcinoma (OSCC), to provide new insight into the pathogenetic mechanisms of OMDs.

Abstract
OBJECTIVE The aim of this study was to assess the HLA haplotype frequencies and genetic profiles of the Kuwaiti population. MATERIALS AND METHODS Whole venous blood was obtained from 595 healthy, unrelated Kuwaiti volunteers. The study population was genotyped for HLA class I (HLA-A, HLA-B, and HLA-C) and class II (HLA-DRB1 and HLA-DQB1) loci using sequence-specific oligonucleotide (SSO) probe-based hybridization and high-resolution HLA genotyping. Haplotype frequencies were estimated using an implementation of the expectation maximization algorithm that resolves both phase and allelic ambiguity. The Kuwaiti population was compared with other populations from the US National Marrow Donor Program (NMDP), by running a principal component analysis (PCA) on the relevant haplotype frequencies. RESULTS The most common HLA class I alleles in Kuwait were HLA-A*02:01g, HLA-C*06:02g, and HLA-B*50:01g with frequencies of 16, 14, and 12%, respectively. The most common HLA class II alleles in Kuwait were HLA-DQB1*02:01g and HLA-DRB1*07:01 with frequencies of 29.7 and 16.5%, respectively. The most common Kuwaiti haplotype observed was HLA-A*02:01g∼HLA-C*06:02g∼HLA-B*50:01g∼HLA-DRB1*07:01∼HLA-DQB1*02:01g at a frequency of 2.3%. The PCA demonstrated close genetic proximity of the Kuwaiti population with Middle Eastern, Southeast Asian, and North African populations in the NMDP. CONCLUSION Identifying the haplotype diversity in the Kuwaiti population will contribute to the selection of an HLA-match for HSCT, disease associations, pharmacogenomics, and knowledge of pop-ulation HLA diversity.
