Abstract

Background/aims: It has been reported that cases of Helicobacter pylori (H. pylori) gastritis, those with epithelial hyperproliferation, have potential for malignant transformation. This study was planned to determine the effects of H. pylori on gastritis and the gastric epithelial cell proliferation. Methods: In this study, we re-evaluated biopsy samples obtained from 331 cases of chronic gastritis according to Sydney criteria, retrospectively. We examined the gastric epithelial cell proliferation with proliferating cell nuclear antigen in the proliferating zone, in the whole mucosa of intestinal metaplasia and in areas of regenerative atypia, separately. Results: The relationship between H. pylori colonization density and chronic active gastritis was statistically significant. We did not see any relationship between the presence and density of H. pylori in gastric mucosa via proliferating cell nuclear antigen indices. In the presence of lymphoid follicles, we noted a significant expression of proliferating cell nuclear antigen in the areas of whole gastric mucosa and regenerative atypia. Conclusions: In the presence of lymphoid follicles, proliferating cell nuclear antigen expression was observed in the areas of whole gastric mucosa and regenerative atypia, but we did not see any relationship between the presence and density of H. pylori in gastric mucosa via proliferating cell nuclear antigen indices. This observation suggests the role of chronic inflammatory cells in gastric epithelial cell proliferation rather than the bacterium itself.

Özet

Amaç: Helicobacter pylori'nin mide epitelinde hiperproliferasyona yol açarak malign değişikliklere neden olabileceği bildirilmektedir. Bu çalışma Helicobacter pylori'nin gastrit bulguları ile ilişkisini ve mide epiteli proliferasyonundaki rolünü araştırmak için planlandı. Yöntem: Histopatolojik olarak kronik gastrit tanısı almış 331 olgudan elde edilen endoskopik biyopsi materyalleri çalışmaya alındı ve Sydney kriterlerine göre tekrar değerlendirildi. Gastrik hücre proliferasyonunu değerlendirmek için normal proliferatif zon, intestinal metaplazi ve reaktif atipi gösteren alanlarda PCNA ekspresyonu araştırıldı. Bulgular: Helicobacter pylori kolonizasyon yoğunluğu ile kronik aktif gastrit arasında anlamlı bir ilişki saptandı. Helicobacter pylori kolonizasyon yoğunluğu ve varlığı ile proliferasyon indeksleri karşılaştırıldığında anlamlı bir ilişki gözlenmedi. Ayrıca lenfoid folikül izlenen olgularda PCNA tüm katlarda ve rejeneratif atipinin izlendiği alanlarda anlamlı pozitişik gösteriyordu. Sonuç: Lenfoid foliküllerin varlığında, tüm katlarda ve rejeneratif atipinin izlendiği alanlarda PCNA expresyonu gözlendi. Ancak Helicobacter pylori'nin varlığı ve yoğunluğu ile gastrik epiteliyal proliferasyon arasında anlamlı bir ilişki saptanmadı. Bu bulgular gastrik epiteliyal proliferasyon üzerinde Helicobacter pylori'nin kendisinden ziyade kronik inflamatuar hücrelerin gastrik hücre proliferasyonunu uyardığını düşündürmüştür.
