Proton Pump Inhibitor Associated Multiple Gastric Hyperplastic Polyps With Uncontrollable Bleeding: A Case Report. In Vivo 2024; 38:1465-1469. [PMID: 38688629 PMCID: PMC11059861 DOI: 10.21873/invivo.13592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 03/07/2024] [Accepted: 03/08/2024] [Indexed: 05/02/2024]
Abstract
BACKGROUND/AIM The long-term use of proton pump inhibitors (PPIs) has been reported to be strongly associated with the development of fundic gland polyps (FGPs). Conversely, a few cases of gastric hyperplastic polyps (GHPs) associated with PPI use have been reported. We experienced a case of PPI-associated multiple GHPs with uncontrollable bleeding. CASE REPORT A 64 year old man with a history of rheumatoid arthritis presented to the hospital with complaints of vertigo and black stools. Blood tests revealed anemia and hypoproteinemia. Esophagogastroduodenoscopy (EGD) showed blood and black residue accumulated in the stomach. The source of the bleeding was multiple hyperplastic polyps. Bleeding could be stopped even with fasting, and total blood transfusions amounted to 28 units of RBCs were required in 18 days. After the cessation of PPI, EGD showed that the polyps had almost disappeared. Pathological diagnosis of resected polyp was hyperplastic polyp, which was characterized by capillary hyperplasia and edema. Gastrin receptors were over-expressed in the foveolar epithelium and not in the capillaries. Methotrexate (MTX)-induced portal hypertensive gastroenteropathy was revealed during follow-up. We consider that the effect of portal hypertension may have caused the capillary hyperplasia. CONCLUSION Although PPI-related polyps are usually fundic gland polyps and do not cause life-threatening adverse events, we experienced PPI-related GHPs in which hemostasis was difficult to control.

Abstract
Several features of drug-induced mucosal alterations have been observed in the upper gastrointestinal tract, i.e., the esophagus, stomach, and duodenum. These include pill-induced esophagitis, desquamative esophagitis, worsening of gastroesophageal reflux, chemotherapy-induced esophagitis, proton pump inhibitor-induced gastric mucosal changes, medication-induced gastric erosions and ulcers, pseudomelanosis of the stomach, olmesartan-related gastric mucosal inflammation, lanthanum deposition in the stomach, zinc acetate hydrate tablet-induced gastric ulcer, immune-related adverse event gastritis, olmesartan-asso-ciated sprue-like enteropathy, pseudomelanosis of the duodenum, and lanthanum deposition in the duodenum. For endoscopists, acquiring accurate knowledge regarding these diverse drug-induced mucosal alterations is crucial not only for the correct diagnosis of these lesions but also for differential diag-nosis of other conditions. This minireview aims to provide essential information on drug-induced mucosal alterations observed on esophagogastroduodenoscopy, along with representative endoscopic images.

Morphological change of foveolar-type gastric adenocarcinoma after proton pump inhibitor discontinuation in a short time period: A case report. DEN OPEN 2024; 4:e293.

Abstract
A 37-year-old man with systemic lupus erythematosus underwent esophagogastroduodenoscopy as a screening examination for anemia and bloody stool. A semi-pedunculated edematous lobular polyp of 25 mm in size was detected in the greater curvature of the upper gastric body. At that time, a definitive diagnosis of cancer could not be made based on a biopsy specimen from the lesion. Since the patient was on proton pump inhibitor (PPI) for a long time to prevent peptic ulceration due to prolonged prednisolone administration for systemic lupus erythematosus, we diagnosed the lesion as a PPI-associated hyperplastic polyp and switched lansoprazole to famotidine. Two months later, esophagogastroduodenoscopy revealed that the polyp had decreased in size to 8 mm, whereas the biopsy specimen led to a histological diagnosis of gastric cancer. The polyp was removed by endoscopic submucosal dissection. Immunohistochemistry revealed that the tumor cells were positive for MUC5AC, but negative for MUC2 and MUC6, leading to a final diagnosis of foveolar-type gastric adenocarcinoma. In conclusion, we may suggest that PPI induces reversible morphological changes in foveolar-type gastric adenocarcinoma. Furthermore, short-term follow-up of polypoid lesions should be prepared, considering tumor comorbidity with morphological changes during long-term PPI usage.

Abstract
BACKGROUND/AIMS Multiple white and flat elevated lesions (MWFL) that develop from the gastric corpus to the fornix may be strongly associated with oral antacid intake. Therefore, this study aimed to determine the association between the occurrence of MWFL and oral proton pump inhibitor (PPI) intake and clarify the endoscopic and clinicopathological characteristics of MWFL. METHODS The study included 163 patients. The history of oral drug intake was collected, and serum gastrin levels and anti-Helicobacter pylori immunoglobulin G antibody titers were measured. Upper gastrointestinal endoscopy was performed. The primary study endpoint was the association between MWFL and oral PPI intake. RESULTS In the univariate analyses, MWFL were observed in 35 (49.3%) of 71 patients who received oral PPIs and 10 (10.9%) of 92 patients who did not receive oral PPIs. The occurrence of MWFL was significantly higher among patients who received PPIs than in those who did not (p<0.001). Moreover, the occurrence of MWFL was significantly higher in patients with hypergastrinemia (p=0.005). In the multivariate analyses, oral PPI intake was the only significant independent factor associated with the presence of MWFL (p=0.001; odds ratio, 5.78; 95% confidence interval, 2.06-16.2). CONCLUSION Our findings suggest that oral PPI intake is associated with the presence of MWFL (UMINCTR 000030144).

Long-term vonoprazan administration causes gastric fundic gland-type hyperplastic polyps and chronic bleeding. Clin J Gastroenterol 2022; 16:159-163. [PMID: 36586091 DOI: 10.1007/s12328-022-01751-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 12/26/2022] [Indexed: 01/01/2023]
Abstract
A patient experienced gastric fundic gland-type hyperplastic polyps, consisting of foveolar epithelium and parietal cells, complicated with chronic bleeding due to long-term treatment with vonoprazan. The patient had progressive anemia, probably caused by bleeding from the polyps. After switching from vonoprazan to a histamine-2 (H2) receptor antagonist, the polyps markedly shrank and the anemia improved. Vonoprazan can produce reversible hyperplastic polyps and anemia. In case of anemia in patients receiving long-term vonoprazan, it is important to consider drug cessation or change to an H2 blocker.

Abstract
The incidence of gastrointestinal (GI) mucosal diseases, including various types of gastritis, ulcers, inflammatory bowel disease and GI cancer, is increasing. Therefore, it is necessary to identify new therapeutic targets. Ion channels/transporters are located on cell membranes, and tight junctions (TJs) affect acid–base balance, the mucus layer, permeability, the microbiota and mucosal blood flow, which are essential for maintaining GI mucosal integrity. As ion channel/transporter dysfunction results in various GI mucosal diseases, this review focuses on understanding the contribution of ion channels/transporters to protecting the GI mucosal barrier and the relationship between GI mucosal disease and ion channels/transporters, including Cl−/HCO3− exchangers, Cl− channels, aquaporins, Na+/H+ exchangers, and K+ channels. Here, we provide novel prospects for the treatment of GI mucosal diseases.

Gastroprotective Effect of Enteral Nutrition Formula in Mice Injected Subcutaneously with Indomethacin. Nutrients 2021; 13:nu13093297.

Abstract
We have previously shown that two enteral nutrition formulas suppressed gastric lesions induced by the oral administration of indomethacin (IND) in mice. However, the mechanism of their protective effect is unknown. In this study, the effect of the two enteral nutrition formulas on gastric lesions induced by subcutaneous IND injection was investigated, with the objective of exploring the possibility that they may interact directly with IND in the gastrointestinal tract. Ten-week-old, male, ICR mice were fasted, then orally given either purified water, Mermed® One, or 2-fold diluted Terumeal® 2.0α as enteral nutrition formula (25 mL/kg). IND was injected subcutaneously at 20 mg/kg after 30 min, and the stomach was removed 6 h later and fixed in formalin. The number and area of lesions in the stomachs of mice given enteral nutrition formula was reduced to 56–89% and 34–61%, respectively, compared with the mice given purified water. The time courses of plasma IND concentrations were comparable among the three groups. These results suggested that the effect of these enteral nutrition formulas on gastric lesions did not originate from their direct interaction with IND in the gastrointestinal tract or their effect on the disposition of IND.

Abstract
Pseudopolyps, a type of remnant oxyntic mucosa on a background of corpus-restricted mucosal atrophy, are a characteristic endoscopic finding in autoimmune gastritis (AIG). Linear or nodular enterochromaffin-like (ECL) cell hyperplasia, a characteristic histopathological finding of AIG, is not generally found in pseudopolyps. We report a case of AIG with fundic gland polyp (FGP)-like pseudopolyps containing nodular ECL cell hyperplasia. A 64-year-old man underwent esophagogastroduodenoscopy, which revealed atrophic changes limited to the corpus, with a normal antrum. The greater curvature was less atrophic than the lesser curvature. Sessile or semipedunculated polypoid lesions were observed on the greater curvature and on the anterior and posterior walls of the corpus. The polypoid lesions resembled FGPs, although some were larger than FGPs generally are. Histologically, non-atrophic fundic glands with parietal cell pseudohypertrophy were observed in the upper regions of the polypoid lesions. By contrast, at the base of the lesions, where linear and nodular ECL cell hyperplasia was identified by immunohistochemical staining, destruction of fundic glands with lymphocytic infiltration, loss of parietal cells, and pseudopyloric metaplasia was observed. Anti-parietal cell antibody positivity and hypergastrinemia confirmed the diagnosis of AIG with pseudopolyps. FGP-like pseudopolyps can, therefore, be present with nodular ECL cell hyperplasia in AIG.

Abstract
Hyperplastic polyps are the second most common type of gastric polyp in the United States with equal incidence in both genders, usually found incidentally during endoscopic examinations. It is a well-known fact that they are associated with iron-deficiency anemia due to chronic blood loss. We present a case of a 69-year-old man with a relatively small hyperplastic gastric polyp with acute upper gastrointestinal bleeding, presenting with melena and acute blood loss anemia requiring admission to intensive care unit and urgent endoscopic intervention with hot snare removal of the polyp and cautery of surrounding area with excellent hemostasis. The pathology revealed focal intestinal metaplasia and low-grade dysplasia with no evidence of malignancy. He was subsequently discharged with outpatient follow-up with gastroenterology.

Abstract
We investigated the effects of enteral nutrition formula on non-steroidal anti-inflammatory drug (NSAID)-induced gastric lesions in mice. Male ICR mice aged 7–9 weeks old were fasted, then orally given either purified water, Mermed® One, or 2-fold diluted Terumeal® 2.0α as enteral nutrition (25 or 50 mL/kg each). Indomethacin (IND) was orally administered at 20 mg/kg after 30 min, and the stomach was removed 6 h later and fixed in formalin. The number and area of lesions in the stomachs of the mice given enteral nutrition showed a significant, dose-dependent decrease compared to the purified water-treated group, and no significant difference was seen between the two enteral nutrition-treated groups. Comparable time courses of plasma IND concentrations suggest that enteral nutrition does not inhibit gastrointestinal absorption of IND. Our findings indicate that administering enteral nutrition could inhibit the onset of NSAID-induced gastric ulcers.

Abstract
Background/Aims: While the occurrence of multiple whitish flat elevated lesions (MWFL) was first reported in 2007, no studies on MWFL have been published to date. The present retrospective observational study aimed to clarify the endoscopic findings and clinicopathological features of MWFL.
Methods: Subjects were consecutive patients who underwent upper gastrointestinal endoscopy as part of routine screening between April 2014 and March 2015. The conventional white-light, non-magnifying and magnifying narrow-band images were reviewed. Clinical features were compared between patients with and without MWFL.
Results: The conventional endoscopic findings of MWFL include multiple whitish, flat, and slightly elevated lesions of various sizes, mainly located in the gastric body and fundus. Narrow-band imaging enhanced the contrast of MWFL and background mucosa, and magnifying narrow-band imaging depicted a uniformly long, narrow, and elliptical marginal crypt epithelium with an unclear microvascular pattern. Histopathological findings revealed hyperplastic changes of the foveolar epithelium, and parietal cell protrusions and oxyntic gland dilatations were observed in the fundic glands, without any intestinal metaplasia. The rate of acid-reducing drug use was significantly higher in patients with MWFL than in those without (100% [13/13] vs. 53.7% [88/164], p<0.001).
Conclusions: The present study indicated a relationship between the presence and endoscopic features of MWFL and history of acidreducing drug use.
