Abstract:

Background and purpose : The objective of this study was to evaluate the role of several risk factors in upper gastrointestinal bleeding (ÜGÏB) from peptic ulcers. Materials and methods : Patients with acute ÜGÏB due to peptic ulcers and control patients with peptic ulcer disease without bleeding were enrolled. Üpper GÏ endoscopy and rapid urease test for evaluation of Helicobacter pylori infection were performed in both groups. The relation of the following variables with the risk of ÜGÏB were assessed: sex, age, smoking, previous history of bleeding, non-steroidal anti-inflammatory drugs (NSÂÏD) use, ulcer size, ulcer location, duration of acid-peptic disease and Helicobacter pylori status. Multivariate logistic regression analysis was performed to identify independent risk factors. Results : Â total of 161 cases of ÜGÏB and 287 patients with non-bleeding peptic ulcer were enrolled in the study. Ünivariate analysis showed that smoking and duration of acid-peptic disease were not different in the case and control groups. The odds for the following factors were resulted in the logistic regression analysis: gastric ulcer / duodenal ulcer 11.90 (95% ÇÏ: 4.04-35.03), previous GÏ bleeding 7.72 (95% ÇÏ: 4.39-13.58), ulcer size 2.63 (95% ÇÏ: 1.20-5.77), NSÂÏD-use 2.21 (95% ÇÏ: 1.17-4.20), male sex 1.71 (95% ÇÏ: 1.01-2.89) and age by increasing the risk as 1.03 for every year increase in age (95% ÇÏ: 1.01-1.04). H. pylori was not an independent factor in the multivariate analysis (ÔR=0.49, 95% ÇÏ: 0.23-1.04). Çonclusion : The risk of ÜGÏB is strongly related to gastric ulcer, previous history of bleeding, ulcer size, and NSÂÏD use. Ïn an area with high prevalence of H. pylori infection, this infection may not be a risk factor for bleeding from peptic ulcers.

بررسی پلی مورفیسم ژن کاتالاز در بیماران دچار زخم پپتیک

چکیده مقدمه: بیماری زخم پپتیک (PUD)، نماینده گروهی از زخم‌های بخش بالایی دستگاه گوارشی، در معده و دوازدهه است. استرس اکسیداتیو و رادیکال‌های آزاد، از عوامل دخیل در پاتوژنز این بیماری است. سلول‌ها برای از بین بردن گونه‌های فعال اکسیژن از چندین آنزیم با فعالیت آنتی‌اکسیدانی استفاده می‌کنند. یکی از این آنزیم‌های، کاتالاز است که پراکسید هیدروژن را به آب و اکسیژن تبدیل می‌کند. هدف: بررسی ارتباط پلی‌...

آنتی‌بادی ضد CagA، روش جدید تشخیص بیماری زخم پپتیک از دیس‌پپسی بدون زخم: مطالعه مورد شاهدی

Background: Helicobacter pylori is a gram negative microaerophilic spiral bacilli, which causes duodenal and gastric ulceration. Also this organism cause distal gastric adenocarcinoma and primary gastric lymphoma. The most important Helicobacter pylorus virulence factor is cytotoxin associated gene A (cagA) Pathogenicity Island that cause secretion of antibody by stimulation of immune system. M...

بررسی شیوع حذف قطعه bp4977 از ژنوم میتوکندریایی در بیماران مبتلا به زخم پپتیک

Background and Aim: A peptic ulcer is a breach in the gastric or duodenal mucosa down to the submucosa. There is evidence concerning the role of Reactive Oxygen Species (ROS) in the genesis of such ulcers production of intracellular ROS along mitochondria oxidative phosphorylation (OXPHOS) predisposes the deletion of 4977 bp mtDNA. The aim of the present study was to evaluate the association of...
