Abstract: Background: Studies with latest technologies such as endoscopy with magnification and chromoendoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. Aim:To validate the morphologic features of gastric mucosa related to H. pylori infection gastritis allowing predictability of their diagnosis as … Show more

“…59 Flat erosions are generally <5 mm in diameter and <1-mm depth, and contain a fibrin exudate, and sometimes haematin. 19 Previous studies have discovered equivocal results for these findings as predictors of H pylori status, 19,22,42 and the results of this analysis agree with this, suggesting that erosions or haem flecks do not carry predictive significance.…”

“…[12][13][14] In the modern era of high-definition endoscopy, the RAC has been confirmed as an important endoscopic predictor of an H pylori-naïve stomach, which is visible by careful observation without the aid of magnification. 15,16 Further mucosal features, including diffuse erythema, 17,18 linear erythema, 17,19 gastric erosions, 19 mucosal oedema, 20 swollen gastric folds, 20 mosaic appearance of mucosa, 18 fundic gland polyps, 19 mucosal atrophy, intestinal metaplasia 21 and gastric antral nodularity, 22 have been proposed to predict H pylori status. These features, and others, have been investigated to varying degrees, using a variety of endoscopic imaging modalities and study designs, and the Kyoto classification of gastritis divides patients into three groups: H pylori naïve (nongastritis), patients with current infection (active gastritis) and patients with past H pylori infection (inactive gastritis).…”

“…Because HP is the most common infection in humans, and as a consequence of its chronic character, may trigger serious diseases with considerable morbidity 1 , 3 , 4 , 5 , 8 , 13 , 19 , 20 , 30 . Comparative study of its prevalence in distinct regions over the years is of great importance to analyze if the health improvement of population translate into reducing the prevalence, as well as guiding strategies and guidelines for the prevention and specific treatment for each area proportional to the degree of socioeconomic and cultural development 2 , 7 , 11 , 12 , 14 , 20 , 26 , 28 , 29 .…”

“…A single-center study reported that H. pylori -associated gastritis was connected with endoscopic modifications and histopathology in a prospective cohort of children 19 . It was also shown that the conventional endoscopy features can be used to diagnose H. pylori 20 21 22 , but the efficiency of WLE was relatively poor 23 24 . Endocytoscopy may facilitate in vivo gastric mucosal histopathology 25 , but it is time-consuming and some patients cannot tolerate it.…”
