Helicobacter pylori Associated Lymphocytic Gastritis in a Child / 대한소아소화기영양학회지

Lymphocytic gastritis (LG) is a rare subtype of chronic gastritis. It is defined as dense proliferation of intraepithelial lymphocytes (IELs) more than 25 lymphocytes per 100 epithelial cells. The known major causes of LG are celiac disease and Helicobacter pylori infection. H. pylori associated LG (HpLG) has more enhanced cytotoxic and apoptotic tendencies than chronic H. pylori gastritis. A 12-year-old girl with postprandial epigastric pain was diagnosed HpLG on endoscopic biopsy. After the 1st eradication therapy, H. pylori bacilli were still found, and urea breathing test was positive. Although the endoscopic finding was partially improved, clinical symptoms and histologic finding were persisted. We could achieve the improvement of clinical symptoms and disappearance of IELs after the 2nd eradication. The discordant of histopathologic and endoscopic improvement occurred after the 1st eradication therapy of HpLG. Therefore the clinical and histopathologic evaluation should be considered as well as endoscopic findings.

Linfoma MALT gástrico, gastritis linfocitaria y enfermedad celíaca: caso clínico con seguimiento a largo plazo, post erradicación de Helicobacter pylori y regresión del MALT. Correlación Clínico-Endoscópica-Patológica / Gastric MALT lymphoma, lymphocytic gastritis and celiac disease: case report with long-term follow-up post helicobacter pylori eradication and regression of MALT: clinical-pathological and endoscopic correlation

A case report of 61 year old female patient with diarrhea syndrome, whose study showed the presence of low-grade MALT gastric lymphoma associated with lymphocytic gastritis and celiac disease. During a six-year period of follow-up, the eradication of Helicobacter pylori determined the remission of the gastric lymphoma and lymphocytic gastritis; celiac disease showed variable activity according to their adherence to dietary treatment. We discuss possible associations and etiology of MALT lymphoma and lymphocytic gastritis, and of the latter with celiac disease.

Se presenta caso de paciente mujer de 61 años con cuadro de síndrome diarreico, cuyo estudio demuestra la presencia de linfoma MALT de bajo grado asociado a gastritis linfocitaria y enfermedad celíaca. Durante su seguimiento de 6 años, la erradicación de Helicobacter pylori, determinó la remisión del linfoma y gastritis linfocitaria, mientras la enfermedad celíaca mostró actividad variable de acuerdo con su adherencia al tratamiento dietético. Se discuten las posibles asociaciones y etiología de linfoma MALT y gastritis linfocitaria, y de esta última con enfermedad celíaca.

Gastritis colágena: presentación de un caso clínico y revisión de la literatura / Collagenous gastritis: presentation of a clinical case and review of the literature

Collagenous gastritis (CG) is an exceptional disease characterized by the deposition of subepithelial collagen band thicker than 10 tm in association with increased inflammatory cell infiltrate of the lamina propria. These histological features seem to overlap with other "collagenous enterocolitides". The pathogenesis and prognosis of CG still remains unclear. CG presentation is seen completely different in two major subsets of patients, children and adults. We report a 38 year-old man with abdominal pain and chronic diarrhea. The upper endoscopy showed a severe gastritis with biopsies that revealed CG, and the colonoscopy was normal with biopsies indicative of collagenous colitis. This characteristic form of clinical presentation in adult patients suggests that subepithelial collagen deposition may be a generalized disease affecting different areas of the gastrointestinal tract. The patient was treated with proton-pump-inhibitors and budesonide, with clinical improvement.

La gastritis colágena (GC) es una enfermedad poco frecuente caracterizada por el depósito subepitelial de colágeno de grosor mayor de 10 um asociado a infiltrado inflamatorio en la lámina propia. Estos hallazgos histológicos son similares a los encontrados en la enterocolitis colágena. La patogénesis y pronóstico de la GC permanece aún desconocida. La presentación clínica de la GC se observa de manera diferente en dos subgrupos de pacientes, niños y adultos. Se presenta el caso de un hombre de 38 años con dolor abdominal y diarrea crónica. La endoscopia digestiva alta mostró una gastritis severa con biopsias que revelaron la presencia de GC y la colonoscopia fue normal con biopsias que mostraron una colitis colágena. Esta forma de presentación clínica en el paciente adulto sugiere que el depósito de colágena subepitelial corresponde a una enfermedad generalizada que puede afectar a diferentes áreas del tracto gastrointestinal. El paciente fue tratado con inhibidores de la bomba de protones y budesonida con mejoría clínica.

Lymphocytic Gastritis in Helicobacter pylori-positive Gastric MALT Lymphoma: Report of Two Cases / 대한소화기학회지

Both lymphocytic gastritis and gastric mucosa associated lymphoid tissue (MALT) lymphoma are associated with Helicobacter pylori (H. pylori) infection. However, this association has not been fully elucidated. We report two cases of lymphocytic gastritis in 57-year-old male and 47-year-old female patients which were diagnosed after the H. pylori eradication to treat gastric MALT lymphoma. MALT lymphoma was successfully treated in case 1, but residual MALT lymphoma remained in case 2. During the follow-up endoscopic examinations, several elevated erosions in case 1 and irregular mucosal atrophy in case 2 were newly detected. Biopsy specimens showed marked infiltration of lymphocytes in the surface epithelium (56.6+/-15.9 intraepithelial lymphocytes (IELs)/100 epithelial cells in case 1 and 40.5+/-9.3 IELs/100 epithelial cells in case 2), which were exclusively CD8-positive T lymphocytes. These findings suggest that H. pylori infection may cause a monoclonal proliferation of B lymphocytes, leading to MALT lymphoma as well as polyclonal proliferation of T lymphocytes which subsequently infiltrated into the surface epithelium as a host immune reaction, resulting in lymphocytic gastritis.

Incidence of Lymphocytic Gastritis in Endoscopic Corporeal Varioliform Gastritis / 대한소화기내시경학회지

BACKGROUND/AIMS: Lymphocytic gastritis is characterised by the accumulation of small lymphocytes in the surface and foveolar epithelium. It is a common finding in a subtype of gastritis characterized by the presence of nodules and erosions in the body, relative to which the antrum was spared-'varioliform gastritis'. Lymphocytic gastritis usually follows a chronic course and presents severe clinical symptoms including hypoproteinemia. The aim of this study was to investigate the incidence and clinical manifestations of lymphocytic gastritis in patients who showed endoscopic apprearance of enlarged folds, erosions, and aphthoid nodules in the body. Materials and METHODS: The clinical and histological findings of varioliform gastritis with presence of nodules and erosions in the body were analyzed. The ratio of 25 lymphocytes/100 epithelial cell was used as the criteria for the diagnosis of lymphocytic gastritis in the study. RESULTS: Twenty nine cases were classified as varioliform gastritis (there were 20 men/9 women and average age was 48.9 years). Among the 29 varioliform gastritis, 9 corresponded to lymphocytic gastritis. H. pylori infection rate was 44% (4/9) in lymphocytic gastritis and 65% in non lymphocytic gastritis. There was no difference in H. pylori infection rate between the lymphocytic gastritis and non lymphocytic gastritis. Clinical laboratory findings of lymphocytic gastritis were normal. The patients with lymphocytic gastritis had absence of mild degree of symptoms. Among 4 patients with follow-up endoscopy, erosions in body were completely disappreared in 3 patients. CONCLUSIONS: Lymphocytic gastritis occurred in about 30% of patients with varioliform gastritis. Most patients with lymphocytic gastritis had no symptoms or only mild symptoms and had no significant abnormality in clinical or laboratory finding.
