Ulcer is a common gastrointestinal disorder which is seen among many people. It is basically an inflamed break in the skin or the mucus membrane lining the alimentary tract. Ulceration occurs when there is a disturbance of the normal equilibrium caused by either enhanced aggression or diminished mucosal resistance. It may be due to the regular usage of drugs, irregular food habits, stress, and ...

The formation of new blood vessels seen in conditions commonly associated with Helicobacter pylori (H. pylori) infection, including gastritis, peptic ulcer, and gastric carcinoma, prompts consideration of a potential relationship between mucosal colonization by this organism and the angiogenic process. H. pylori directly or indirectly damages endothelial cells, which induces a number of changes...

BACKGROUND Virulence factors of Helicobacter pylori are associated with peptic ulcer disease and may be also associated with the efficacy of treatment. AIMS To determine the relation between the vacA and the cagA status of H pylori, clinical disease, and treatment outcome. PATIENTS 121 patients with H pylori infection and peptic ulcer disease or functional dyspepsia were treated by quadrupl...

Despite the decreasing frequency of Helicobacter pylori-induced peptic ulcers, peptic ulcer disease remains a major clinical problem partly because nonsteroidal anti-inflammatory drug ulcers have increased in frequency. The reduction in nonsteroidal anti-inflammatory drug ulcers by use of selective cyclooxygenase-2 inhibitors will not eliminate the problem because of increased use of aspirin fo...

Antibiotics, commonly amoxycillin, tetracycline, metronidazole and clarithromycin, are presently used in combination with anti-ulcer agents such as omeprazole, colloidal bismuth subcitrate, and sucralfate to treat Helicobacter pylori infection in patients with peptic ulcer, and compelling evidence has accumulated that eradication of the organism prevents duodenal ulcer relapse. The latest combi...

BACKGROUND It is not yet known which types of Toll-like receptors (TLRs) are most effective in Helicobacter pylori (H. pylori) recognition. It is also not known which gastric zones have the most prominent roles in TLR-mediated bacterial recognition. The aim of this work was to analyze the expression of TLR2 and TLR4 in biopsy specimens from H. pylori-infected patients. METHODS Thirty-eight pa...

The relationship between the secretion of pepsin 1 (the most electronegative of the pepsins), and the smoking habits of 219 patients has been investigated. Significantly more cigarette smokers with peptic ulceration (72.5%) secreted pepsin 1 in greater than trace amounts after pentagastrin or histamine than did non-smokers with ulceration (51.2%). Differences of a similar order were found for m...

In a prospective study designed to assess the effect of Helicobacter pylori eradication on peptic ulcer healing, 85 consecutive patients with H. pylori-positive peptic ulcer disease were treated with a triple therapy regimen consisting of colloidal bismuth subcitrate 120 mg four times daily for 28 days, with metronidazole 400 mg three times daily and tetracycline 500 mg three times daily for th...

A peptic ulcer in a child looks the same as it does in an adult, and many of the aetiologies of peptic ulcer disease in children are similar to those in adults. However, there are many differences between children and adults, especially in the areas of clinical presentation, the prevalences of different types of ulcer disease, and the prevalence of complications of ulcer disease. Therefore the ...
