1/128. Eradication of helicobacter pylori heals atrophic corpus gastritis caused by long-term treatment with omeprazole.Long-term treatment with proton pump inhibitors in patients with helicobacter pylori gastritis can lead to atrophic changes in the corpus mucosa. What is still unclear, however, is whether this atrophy can regress in response to helicobacter pylori eradication. We report on a male patient with helicobacter pylori gastritis receiving long-term treatment (4 years) with omeprazole for gastrooesophageal reflux disease, who developed autoaggressive gastritis with progressive atrophy, hypochlorhydria, hypergastrinaemia and nodular ECL-cell hyperplasia. To determine whether these changes might be induced to regress, helicobacter pylori eradication therapy was administered. Ten months after helicobacter pylori eradication autoaggressive lymphocytic infiltrates were no longer detectable, and the glands in the corpus mucosa had normalised despite continued treatment with omeprazole - a finding that was confirmed at two further follow-up surveys performed at 6-month intervals. This case report shows that atrophy of the corpus mucosa developing under long-term treatment with a proton pump inhibitor can be cured by eradicating helicobacter pylori.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
2/128. multiple myeloma involving the stomach with vitamin B12 deficiency.Involvement of the gastrointestinal tract by plasmocytoma is rare. In a 78-year-old man with IgA lambda multiple myeloma stage IIIB, the evaluation of a megaloblastic anaemia revealed a subnormal vitamin B12 level. Urinary excretion of isotope-labelled vitamin B12 was reduced. Tests for gastric parietal cell and intrinsic factor antibodies were negative. There were no clinical signs of an insufficient absorption in the ileum. biopsy specimens of the stomach showed a dense, diffuse infiltrate of malignant plasma cells in the lamina propria of fundus and corpus. A urease test for helicobacter pylori was positive. There was a minor haematological improvement when vitamin B12 was given parenterally. Several combinations of cytostatic drugs had no effect on the manifestations of the multiple myeloma. In our patient the vitamin B12 deficiency may be related to a displacement or destruction of parietal cells by malignant plasma cells.- - - - - - - - - - ranking = 1.2346911329828keywords = lamina propria, propria, lamina (Clic here for more details about this article) |
3/128. Simultaneous MALT-type lymphoma and early adenocarcinoma of the stomach associated with helicobacter pylori gastritis.We report about two cases of combined gastric lymphoma and gastric carcinoma with one of them representing a case of early gastric high grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) with co-existing early gastric adenocarcinoma. In contrast to most previously reported similar cases, in both of our cases the definitive diagnosis of gastric lymphoma and carcinoma was obtained preoperatively. This, however, seems to be in future times an essential prerequisite for employing minimal invasive methods such as eradication therapy in the case of diagnosed early lymphoma and endoscopic treatment for early gastric carcinomas. These methods have been proven to be an effective and beneficial alternative treatment especially with regard to the life quality of the patients.- - - - - - - - - - ranking = 0.33333333333333keywords = mucosa (Clic here for more details about this article) |
4/128. Eradication of helicobacter pylori infection did not lead to cure of duodenal mucosa-associated lymphoid tissue lymphoma.Duodenal mucosa-associated lymphoid tissue (MALT) lymphoma is very rare, and little is known about its clinical course or association with helicobacter pylori infection. This report describes the case of a 76-year-old man with a polypoid mass in the duodenal bulb, diagnosed as low-grade MALT lymphoma. H. pylori infection in the duodenal mucosa was confirmed by histology with silver stain. Endoscopic examination showed that the gross lesion regressed after the eradication of H. pylori despite its histopathologic persistence. Ten months later, however, cervical and intraperitoneal lymphadenopathy and bone marrow involvement was observed, and the pathologic diagnosis of the cervical lymph node was identical with that of the duodenal lesion.- - - - - - - - - - ranking = 2keywords = mucosa (Clic here for more details about this article) |
5/128. helicobacter heilmannii associated erosive gastritis.The spiral bacteria, helicobacter heilmannii (H. heilmannii), distinct from helicobacter pylori (H. pylori), was found in the gastric mucosa of a 71-year-old man without clinical symptoms. The endoscopic examination revealed erosive gastritis. Rapid urease test from the antral specimen was positive, but both culture and immunohistological staining for H. pylori were negative. touch smear cytology showed tightly spiral bacteria, which were consistent with H. heilmannii. At the second endoscopy after medication regimen for eradication of H. pylori, inflammation was decreased and the rapid urease test was negative. The second cytology showed no evidence of H. heilmannii. Anti-H. pylori therapy may be a useful medication for H. heilmannii.- - - - - - - - - - ranking = 0.33333333333333keywords = mucosa (Clic here for more details about this article) |
6/128. Successful symptomatic management of a patient with Menetrier's disease with long-term antibiotic treatment.We present the case of a 79-year-old female patient with criteria typical for Menetrier's disease, i.e. enlargement of the gastric folds due to foveolar hyperplasia associated with severe protein-loss along with epigastric pain, nausea, vomiting and weight loss. Gastrin levels were within the normal range, but elevated helicobacter pylori antibody titers (83 microg/ml) were indicative of a recent infection. Histologic examination of a gastric polyp, which was removed in toto, revealed the presence of early gastric cancer of the mucosal type. After initiation of antibiotic treatment with clarithromycin (3 x 250 mg/day) and metronidazole (2 x 500 mg/day) in combination with lansoprazole (30 mg/day), the patient's condition improved rapidly along with abrogation of protein loss. Under maintenance treatment as indicated above, the patient has been free of symptoms now for a period of more than 2 years. On repetitive endoscopic follow-up, there was no change in gastric mucosa morphology either endoscopically or histologically, and also no evidence of recurrence of a malignant lesion. We conclude that this therapeutic regimen represented an effective alternative to surgical intervention in this patient and should be considered in similar cases.- - - - - - - - - - ranking = 0.66666666666667keywords = mucosa (Clic here for more details about this article) |
7/128. angioedema due to acquired C1-esterase inhibitor deficiency in a patient with helicobacter pylori infection.The first component of the classical pathway of the complement system, C1 is regulated by a serum protein, the C1-esterase inhibitor (C1-INH). Deficiency of this protein leads to the release of vasoactive mediators (C2 kinin and bradykinin) that increase vascular permeability and can induce edema formation in subcutaneous and submucosal tissues. The genetic variant of C1-INH deficiency is inherited as an autosomal dominant trait and causes hereditary angioneurotic edema. The acquired form of C1-INH deficiency is characterized by similar manifestations and can occur in association with lymphoproliferative diseases, malignancy, immune disorders, and infections. The authors present a case of acquired C1-INH deficiency in a patient with helicobacter pylori infection. Complete eradication of this pathogen was followed by the resolution of symptoms and normalization of serum complement levels. It seems therefore probable that in this patient, acquired C1-INH deficiency was related to helicobacter pylori infection. To our best knowledge, no similar observations have been published so far. Specific immune reactions are important contributing factors in H. pylori. Excessive consumption of complement by antibodies directed against H. pylori is a potential cause of C1-INH deficiency observed in our case.- - - - - - - - - - ranking = 0.33333333333333keywords = mucosa (Clic here for more details about this article) |
8/128. A case of prurigo and lichenified plaques successfully treated with proton pump inhibitor.A case of prurigo and lichenified plaques successfully treated with proton pump inhibitor is presented. She presented with pruritic eruptions, which showed marked lichenification and prurigo nodules, on her trunk and extremities. She had been treated with steroid ointment and H1-histamine receptor antagonist without success. Laboratory examinations revealed increased eosiophils and elevated lactate dehydrogenase. The skin biopsy specimen showed moderate acanthosis with spongiosis and lymphocytic and eosinophilic infiltration into the upper dermis. Because of vomiting and epigastralgia, endoscopical examination was performed, and an ulcer was found at the angle of her ventricle. A biopsy specimen disclosed a benign gastric mucosa with moderate inflammation within the lamina propria, and organisms consistent with helicobacter pylori. Treatment for gastric ulcer with proton pump inhibitor (omeprazole) and aluminium hydroxide gel improved her eruptions and her pruritus resolved. She was discharged with complete cure of her eruption and ventricular ulcer. Our case indicates that gastric lesions induced by helicobacter pylori infection may play an important role in dermatological diseases. proton pump inhibitors including omeprazole are one of the choices for the treatment of some dermatological diseases including prurigo and lichenified plaques.- - - - - - - - - - ranking = 1.5680244663161keywords = lamina propria, mucosa, propria, lamina (Clic here for more details about this article) |
9/128. Spontaneous regression of malignant lymphoma of the stomach.We report a case of complete and spontaneous regression of malignant lymphoma of the stomach. A submucosal tumor with central ulceration was detected on the greater curvature of the stomach in a 63-year-old woman. The tumor was diagnosed histopathologically as a diffuse large B-cell lymphoma (REAL classification). The tumor disappeared 18 days later without chemotherapy. Examination at that stage showed helicobacter pylori (H. pylori), which was later treated with antibiotics. There was no evidence of recurrence of the malignant lymphoma at the last follow-up conducted at the time of preparation of this report, 13 months after the initial diagnosis. Spontaneous regression of an intermediate and high-grade non-Hodgkin's lymphoma is uncommon. We discuss the possible role of H. pylori in the regression of gastric malignant lymphomas.- - - - - - - - - - ranking = 0.33333333333333keywords = mucosa (Clic here for more details about this article) |
10/128. Rapidly growing primary gastric B-cell lymphoma after eradication of helicobacter pylori.helicobacter pylori (H. pylori) infection plays a decisive role in primary gastric B-cell lymphoma especially of mucosa-associated lymphoid tissue (MALT)-type. We treated a 47-year-old male patient with primary gastric B-cell lymphoma associated with H. pylori infection. Although antibiotic therapy for eradication of H. pylori caused great improvement in the low-grade MALT lymphoma-like lesion, the small areas of high-grade lesion rapidly formed a new bulky mass in only 8 weeks. This suggests that eradication of H. pylori is not effective for high-grade lymphoma.- - - - - - - - - - ranking = 0.33333333333333keywords = mucosa (Clic here for more details about this article) |
