Haematinic deficiencies and patient clinical profiles in Polish patients with recurrent aphthous stomatitis (RAS)

Abstract

Background

RAS is a common ulcerative disorder of the oral mucosa, where the immune impairment may develop in genetically predisposed subjects exposed to certain environmental factors. The aim of the study was to investigate the frequency of anaemia, iron and vitamin B12 deficiency in RAS and to explore its impact on the clinical presentation of RAS.

Methods

A total of 141 adults including: 71 subjects with RAS and 70 controls were enrolled in the study. A detailed dental and haematological assessment, including full blood count, serum iron and vitamin B12 evaluation was performed in all study participants. The results were statistically analysed with Mann-Whitney, Kruskal-Wallis, χ2 and Fisher tests with p<0.05 designated as a significance level.

Results

RAS patients were found to suffer anaemia, iron and vitamin B12 deficiency more frequently than the controls. The mean serum iron levels were also significantly lower in RAS subjects than in controls, although still within the norm. The lowest mean serum iron levels were observed in patients with a mild course of RAS. No significant differences in mean serum iron and vitamin B12 levels were revealed as a function of stratification according to the number of lesions per single flare-up.

Conclusions

The results of our study indicate an association between iron and vitamin B12 deficiency and RAS in a Polish population. However, as the haematinic deficiencies did not significantly modify the course and clinical phenotype of the disease, further studies to explore their role in RAS aetiology are required.
