Abstract

Aim: Chronic gastritis (CG), being one of the most common digestive diseases, is frequently underestimated both by patients and clinicians. However, CG developed as early as in childhood, and often accompanied by Helicobacter pylori contamination of antral mucus, has a persistent recurrent course in adult patients, complicated by mucosal transformations in the form of atrophy, metaplasia and dysplasia. CG can appear as an early stage in the morphogenesis of tumor growth. From this point of view, CG is worth noticing.Materials and Methods: A complex morphological study of antral mucosa in school children with atrophic gastritis has been performed using histochemistry, immunohistochemistry and a morphometric methods. Results: In atrophic gastritis we have revealed the decrease in the number of functionally mature cells responsible for the production of extracellular matrix and basal membrane components, the lack of which in paraepithelial localization results in the change of their special properties. In addition, sulphomucins, non-characteristic of stomach, overlapped on mucosa and in single foveolae have been found in atrophic gastritis.Conclusion: Permanent impairment in the conjugation of cell and tissue components in mucosa accompanied by the change of an epithelial layer synthetic function with the impaired physicochemical properties of gastric mucin results in intestinal metaplasia as early as in childhood.

Özet

Amaç: Çocukluk çağının en sık görülen sindirim sistemi problemlerinden olan kronik gastrit (KG) çoğu kez hastalar ve klinisyenler tarafından küçümsenmektedir. Halbuki çocuklukta başlayıp sıklıkla antral mukusun Helicobacter pylori ile bulaşının eşlik ettiği KG, erişkin dönemde atrofi, metaplazi ve displazi gibi mukoza değişiklikleriyle komplike olan kalıcı, yineleyen bir seyir izlemektedir. KG tümör gelişimi morfogenezinin erken bir evresi olarak ortaya çıkabilir. Bu bakış açısıyla, KG dikkate alınması gereken bir patolojik durumdur.Gereç ve Yöntemler: KG'li okul çocuklarında, histokimyasal, immünohistokimyasal ve morfometrik yöntemlerle antral mukozanın ayrıntılı morfolojik değerlendirilmesi gerçekleştirilmiştir.Bulgular: Atrofik gastritte, paraepitelyal bölgedeki yoklukları, kendilerine özgül özelliklerin değişimiyle sonuçlanan ekstraselüler matriks ve bazal membran bileşenlerinin üretiminden sorumlu fonksiyonel yönden matür hücrelerin sayısında azalma saptadık. Buna ek olarak, yine atrofik gastrik örneklerinde midenin karakteristik bileşeni olmayan sülfomüsinlerin mukoza ve tekli foveolalarda birikimi saptandı.Sonuç: Hücre ve doku bileşenlerinin bağlanımındaki kalıcı hasar ve buna eşlik eden epitelyal tabakanın sentetik fonsiyonunun değişimiyle birlikte gastrik müsinin bozulmuş fizikokimyasal özellikleri, çocukluk çağı gibi çok erken bir dönemde intestinal metaplaziye yol açmaktadır.
