Background:
Upper gastrointestinal bleeding that is related with older patients and NSAIDs use. The frequency of peptic ulcer bleeding varies of 15% to 30% of cases.
Objective:
To determine the gastropathy features of patients who receive nonsteroidal anti-inflammatory drug, and its relation with Helicobacter pylori (Hp).
Methods:
Men and women with GU or DU with or without haemorrhage, were included into two groups, NSAIDs users and non users. We determined the incidence rate of peptic ulcer and the frequencies of risk factors as tobacco use, previous peptic ulcer or haemorrhage, concomitant disease presence and its association with Hp infection.
Results:
We included 434 (67.5%) patients that used NSAIDs and 209 (32.5%) non NSAIDs users control subjects. The average was 62.5 +/- 17.2 years and 49.5 +/- 19.4 years respectively. The annual incidence rate of peptic ulcer in NSAIDs users was 17.5%. Gastrointestinal bleeding was more frequent in NSAIDs users and its relations with Hp infection (23.5%) was smaller than patients without NSAIDs user (47.7%) (OR 0.39 p = 0.0000).
Conclusions:
The GU was highly frequent in the older people who using NSAIDs. The Hp infection shows lower incidence of gastrointestinal bleeding NSAIDs users.

Gastritis II: Pathophysiology
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
