ABSTRACT
Background: Recurrent aphthous stomatitis (RAS) is one of the most frequent inflammatory disorders of theoral mucosa. Cytokines, which play an important role in RAS pathogenesis, participate directly or indirectly innormal, immunological and inflammatory processes and are secreted from cells belonging to innate and adaptiveimmunity as a consequence of microbial and antigenic stimuli. Gene polymorphisms in specific cytokines maypredispose to RAS development. The aim of this study was the investigation and association of IL-10 and TGF-β1gene polymorphisms with RAS.Material and Methods: Studys cohort consisted of 60 Greek patients diagnosed with RAS, including 40 patientswith minor, 10 patients with major and 10 with herpetiform aphthous ulcers. Forty age- and sex-matched controlsubjects were included in this study. DNA was extracted from whole blood samples of all patients and sequencespecific primers (SSP)-based polymerase chain reaction (PCR) was used for genotyping. Gene polymorphisms forcytokines IL-10 at loci -592 and -819 and for TGF-β1 at codon 10 were detected.Results: Significant differences between patients with minor RAS and healthy controls were recorded for IL-10genotypes distribution at position -592 (p=0.042) and -819 (p=0.045) with predominance of C/A and C/T genotypes in RAS patients, respectively. Also, in patients with minor and herpetiform aphthous ulcerations, heterozygousTGF-β1 genotype C/T at codon 10 was associated with increased risk of RAS (p=0.044 and p=0.020, respectively).Conclusions: These data provide evidence that genetic predisposition for RAS and possibly its specific clinical variants is related with the presence of gene polymorphisms for specific cytokines, including IL-10 and TGF-β1, which,in turn, may vary according to geographic origin and genetic background.
