Helicobacter pylori on oral mucosa - topographic distribution

Abstract

Svrha rada bila je ispitati topografsku distribuciju bakterije Helicobacter pylori na oralnoj sluznici u upalnim, ulceroznim i keratotičnim lezijama, kandidijazi i sindromu pečenja usta i usporediti s nalazom na zdravoj sluznici. Primijenili smo nested PCR na citološkim uzorcima uzetim s 9 topografski različitih mjesta oralne sluznice i s različitih oralnih lezija. Od ukupno 426 ispitanika njih 66 (15,49 %) imalo je pozitivan nalaz H. pylori na oralnoj sluznici, bez predilekcije po spolu, ali s većom čestoćom nalaza u starijih ispitanika u usporedbi s mlađima te gotovo jednakom distribucijom na svim ispitanim topografskim stranama oralne sluznice. H. pylori otkriven je u svim ispitanim lezijama i sindromu pečenja usta osim u kandidijazi s većom prevalencijom na sluznici dorzuma jezika i u ulceroznim lezijama, premda bez statistički znatne razlike između lezija i zdrave sluznice (p = 0,059). H. pylori nije patogen za oralnu sluznicu jer kolonizira gotovo s istom čestoćom zdravu i oboljelu oralnu sluznicu. Također ne postoje preferirana mjesta na oralnoj sluznici za naseljavanje H. pylori.The purpose of this study was to examine the topographic distribution of Helicobacter pylori on oral mucosa in various oral lesions such as inflammation, oral ulceration, keratosis, candidiasis and burning mouth syndrome in comparison with healthy oral mucosa. We applied nested PCR on cytologic specimens collected from 9 topographic sites of the healthy oral mucosa and from various oral lesions. Of a total 426 patients 66 (15.49 %) were positive for H. pylori,with no predilection for sex but with higher frequency in older patients, and with almost equal distribution on all examined topographic sites of the oral mucosa. H. pylori was detected in all examined diseases, except in candidiasis, with prevalence on tongue mucosa and in ulcerous lesions although without significant differences between lesions and healthy oral mucosa (p = 0.059). H.pylori is non-pathogenic for oral mucosa since it colonizes almost with the same frequency healthy and diseased oral mucosa. There is no preferential oral site or lesion for colonization of H. pylori
