Evaluation of malignant and benign gastric biopsy specimens by mRNA expression profile and multivariate statistical methods

CYTOMETRY, Issue 5 2007
Orsolya Galamb
Abstract Background: mRNA expression array and multivariate statistical analysis of gastric biopsies can yield insight into the molecular biology basis of local alterations, supporting expression-based identification of morphological alterations. Methods: From 11 patients with erosive gastritis(EG), 5 with adenocarcinoma (GC), 11 with atrophic gastritis (AG) gastric biopsies were collected, total RNA isolated, T7 amplification and expression analysis of 1047 mRNAs was performed using commercial glass arrays (Clontech, USA). After microarray quality control, applicable data were available from 7 EG, 4 GC, and 5 AG. Multivariate statistical and cell functional analysis were performed. Real-time RT-PCR and immunohistochemistry were used for validation. Results: GC was characterized by overregulated v-raf, v-erb-a, BCL2-associated- athanogene, immediate-early-response-3, Polo-like kinase, CDK-2, cyclin-C, Pin1 genes, and downregulated ADP-ribosyltransferase, sialophorin and DCC. AG cases had increased PDGF-receptor, TGF-,-receptor-3, and decreased death-associated-protein-3, ,-1-catenin, topoisomerase-1 levels. In EG upregulation of IGF-receptor-1, CD9, transferrin receptor, integrins, and underexpression of keratin-5, caspase-4 was found. Discriminant analysis could reclassify all samples correctly using four parameters. Conclusions: mRNA expression array analysis of gastric biopsies yields previously known and new data in the evaluation of local gastric alterations. © 2007 Clinical Cytometry Society [source]


Endoscopic classification of chronic gastritis based on a pilot study by the research society for gastritis

DIGESTIVE ENDOSCOPY, Issue 4 2002
Michio Kaminishi
Background:,Various types of classification of gastritis have been proposed, but no plausible classification has been available until now. The Research Society for Gastritis performed a pilot study to establish an endoscopic classification, taking into consideration the following: (i) ease of use; (ii) permitting everyone the common image; and (iii) presence of histopathological evidence. Methods:,One hundred and fifty-five patients were enrolled and underwent gastroscopy. Eight basic endoscopic and histological types of gastritis (superficial, hemorrhagic, erosive, verrucous, atrophic, metaplastic, hyperplastic and special types) were defined. Gastritis was endoscopically diagnosed according to the definition of the endoscopic types of gastritis. Four or more biopsy specimens were obtained from the lesser and the greater curvatures of the antrum and the corpus of each patient, and the histological findings of gastritis and Helicobacter pylori infection were assessed. The histological diagnosis of gastritis was made according to the definition of histology types of gastritis. The endoscopic and the histological diagnoses were then compared in a blinded fashion. Results:,Endoscopic diagnosis was 62% as sensitive as histological diagnosis for erosive gastritis, 67% for verrucous gastritis and 84% for atrophic gastritis in the antrum. In superficial gastritis, sensitivity was approximately 25% in the corpus, but only 8% in the antrum. Metaplastic and hyperplastic gastritis were correctly diagnosed only in severe cases. Conclusion:,Five basic types of gastritis (superficial, erosive, verrucous, atrophic and special types) should be employed for the new endoscopic gastritis classification. Metaplastic and hyperplastic gastritis are considered to be subtypes of atrophic gastritis and they should be excluded from the basic endoscopic classification. A new definition of gastritis in the antrum accompanied by redness still remains to be investigated. [source]


Helicobacter pylori infection in patients with haemophilia in Poland: prevalence and risk of upper gastrointestinal bleeding

HAEMOPHILIA, Issue 4 2005
A. B. Szczepanik
Summary., Infection with Helicobacter pylori is the main aetiological factor for erosive gastritis and duodenal or gastric peptic ulcers often complicated with life-threatening bleeding in patients with coagulation disorders. The aim of this prospective study was to evaluate the prevalence of Helicobacter pylori infection in haemophilia patients, and to assess the risk of gastrointestinal bleeding associated with this infection. From 2000 to 2002, 146 patients with haemophilia (129, haemophilia A; 13, haemophilia B), mean age, 39.9 years (±7.3), were investigated for H. pylori infection using IgG and IgA latex serological test. The control group included 100 men with no coagulation disorders, mean age, 40.9 years (±9.2). For 72 (49.3%) patients with haemophilia and 39 controls (39.0%) serological tests were positive indicating the presence of H. pylori infection (P =0.1112). A history of gastrointestinal bleeding was reported in 46 patients (31.5%) with haemophilia and in two control group patients (2.0%) (P < 0.0001). Gastrointestinal bleeding was significantly more frequent in patients with haemophilia infected with H. pylori (33/46; 71.7%) than in patients with no H. pylori infection (13/46; 28.3%; P = 0.0002). In conclusion, the prevalence of H. pylori infection in haemophilic patients in Poland is comparable with that in patients with no coagulation disorders. Helicobacter pylori infection is a risk factor for duodenal and gastric ulcer bleeding in haemophilia patients. In view of the high frequency of upper gastrointestinal bleeding associated with H. pylori infection, we believe that screening and eradication therapy are appropriate in haemophilia patients.

An unusual cause of dizziness in bulimia nervosa: A case report

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 4 2005
Randy A. Sansone MD
Abstract Objective The current article describes the case of a 23<->year<->old female with purging<->type bulimia nervosa who was evaluated by her primary care physician for dizziness and lightheadedness. Methods After laboratory studies were performed by her primary care physician, the patient was admitted to the hospital because of severe anemia. The patient had been taking nonsteroidal antiinflammatory drugs <(>NSAIDS<)> at prescribed doses for shin splints that were secondary to jogging and developed gastric erosion. Results Endoscopic examination showed that she had diffuse gastritis with linear, streaky ulcerations throughout the body of the stomach. Discussion Lightheadedness is a common clinical symptom among individuals with eating disorders, but is typically related to dehydration, malnutrition, hypometabolism, andor combinations of these factors. Clinicians need to consider NSAID use, which may cause erosive gastritis, blood loss, and lightheadedness. © 2005 by Wiley Periodicals, Inc. [source]


GASTROENTEROLOGY: Prospective evaluation of a clinical guideline recommending early patients discharge in bleeding peptic ulcer

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 9 2010
Marķa Chaparro
Abstract Background and Aim:, To validate an early discharge policy in patients admitted with upper gastrointestinal bleeding (UGIB) due to ulcers. Methods:, Patients with gastroduodenal ulcer or erosive gastritis/duodenitis were included in a previous study aiming to develop a practice guideline for early discharge of patients with UGIB. Variables associated with unfavorable evolution were analyzed in order to identify patients with low-risk of re-bleeding. After that, a one-year prospective analysis of all UGIB episodes was carried out. Results:, A total of 341 patients were identified in the retrospective study. Variables associated with unfavorable evolution were: systolic blood pressure , 100 mmHg, heart rate , 100 bpm, and a Forrest endoscopic classification of severe. 10% of patients were immediately discharged; however, if predictive variables obtained in the multivariate analysis had been used, hospitalization could have been prevented in 34% of patients. A total of 77 patients were included in the prospective analysis. Although only 19.5% of patients were immediately discharged without complications, 29 patients (37.7%) were theoretically suitable for early discharge. Conclusions:, Patients with UGIB who have clean-based ulcers and are stable on admission can be safely discharged immediately after endoscopy. Implementation of the clinical practice guideline safely reduced hospital admission for those patients. [source]
