Type A gastritis is associated with reverse atrophy of the corpus and type B with progressive atrophy extending from the antrum to the corpus. Diffuse or spotty redness in the corpus together with high serum pepsinogen (PG) II levels and a low PG I/II ratio are observed in patients with H. pylori infection when secretory capacity of the stomach is intact. Diffuse-type gastric cancer may develop near the gastric folds, which is a rare site of atrophy. Low serum PG I levels are associated with progressive gastric corpus atrophy and intestinal metaplasia in patients with chronic and previous H. pylori infections. This clinical scenario predisposes patients to intestinal-type gastric cancer, which originates in the atrophic and metaplastic gastric mucosa. Conversely, a high PG I/II ratio is observed in patients without H. pylori infection. Serum PG I levels and the PG I/II ratio are high in patients with acute H. pylori-negative gastritis, including drug-induced gastritis but are significantly low in autoimmune gastritis. Gastric neuroendocrine tumors may develop in patients with autoimmune gastritis or in those with long-term acid suppressant use. Fasting serum gastrin levels and the risk of neuroendocrine tumors are high in both cases. In this review, types of gastritis are summarized along with evaluation performed to determine the secretory capacity of the background gastric mucosa.","PeriodicalId":22895,"journal":{"name":"The Korean Journal of Helicobacter and Upper Gastrointestinal Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44868565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AIG may progress to severe atrophic gastritis secondary autoimmune-mediated parietal cell destruction in the stomach. AIG can be diagnosed based on anti-parietal cell antibody tests and endoscopy, which reveals widespread gastric corpus atrophy in patients with low serum pepsinogen I levels, a low pepsinogen I/II ratio, and elevated serum gastrin levels on serological testing. Tissue biopsy findings, which include mucosal atrophy and lymphocytic infiltration of the lamina propria may be useful for diagnostic confirmation. Decreased gastric acid secretion causes hypergastrinemia and enterochromaffin-like (ECL) cell proliferation, which can lead to neuroendocrine tumor development. Additionally, an autoimmune response results in parietal and chief cell injury, and proliferating ECL cells are detected in the deep mucosal layers in patients with AIG. Therefore, this condition may easily be misdiagnosed as a subepithelial tumor, and establishing a differential diagnosis for other types of subepithelial tumor accompanied by AIG is challenging. We present the case of a 54-year-old woman who was diagnosed with AIG with a concomitant subepithelial tumor based on serologic tests and biopsy findings and underwent wedge resection, which confirmed diagnosis of a schwannoma.","PeriodicalId":22895,"journal":{"name":"The Korean Journal of Helicobacter and Upper Gastrointestinal Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47503112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we compared treatment success rates of tailored therapy (TT) using real-time polymerase chain reaction (RT-PCR) and empirical STT. Methods: This retrospective study included 650 patients with H. pylori infection, who visited Eunpyeong St. Mary’s Hospital in Korea; 343 patients received TT based on RT-PCR assays, and 307 patients received STT. Eradication success was defined as a negative 13 C-urea breath test result 4~8 weeks after treatment completion. Patients who failed first-line therapy and those with clari-thromycin resistance received bismuth-containing quadruple therapy (BQT; PPI+bismuth+metronidazole+tetracycline). Results: Intention-to-treat analysis showed that H. pylori eradication rates were higher in patients who received RT-PCR – based TT than in those who were treated using empirical STT (80.5% [190/236] vs. 70.4% [216/307], P =0.069). Per-protocol (PP) analysis showed similar results (84.4% [190/225] vs. 74.7% [216/289], P =0.007). PP analysis showed that 7-day TT treatment was associated with a higher eradication rate than that observed with 10-to 14-day STT (85.2% [178/209] vs. 73.8% [59/80], P =0.029). The clarithromycin resistance rate was 27.9% (87/312). The eradication success rate was 89.2% (74/83) in patients with clari-thromycin resistance, who received BQT as first-line therapy. Conclusions: The treatment success rate was higher in patients who received 7-day RT-PCR – based TT than in those who were administered 10-to 14-day empirical treatment.

Endoscopic findings are nonspecific and variable; therefore, differentiation of this malignancy from early gastric cancer is challenging during endoscopy. Although an endoscopic biopsy is the gold standard for diagnosis, a biopsy may not conclusively establish the diagnosis in all cases. Diagnostic confirmation requires interpretation of the biopsy specimen findings by an experienced histo-pathologist, and an additional immunoglobulin heavy chain (IgH) rearrangement test may aid with accurate diagnosis. We present a case of gastric MALT lymphoma that histopathologically mimicked signet ring cell carcinoma (SRCC) on evaluation of repeat endoscopic biopsies. Following endoscopic submucosal dissection (ESD), we confirmed the final diagnosis of gastric MALT lymphoma based on histopathological findings of prominent lymphoid infiltrates accompanied by lymphoepithelial lesions and results of the monoclonal IgH rearrangement test. Notably, a few carcinoma-like signet ring cells (SRCs) in the specimen were attributed to a reactive change. Clinicians should be mindful of possible SRCs in gastric MALT lymphoma specimens to avoid misdiagnosis of SRCC in patients with gastric MALT lymphoma. Confirmatory ESD may be useful for accurate diagnosis and appropriate management of such lesions.
