The aim of this study is to study the natural history of the ulcer healing while on proton pump inhibitors (PPI) and the ulcer recurrence without acid suppression therapy of Non-steroidal Anti-inflammatory Drugs (NSAID), non-Helicobacter pylori (HP) bleeding ulcer patients.

Peptic Ulcer

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective Cohort Study to Study the Natural History and Ulcer Recurrence Without Acid Suppression of Non-NSAID, Non-HP Bleeding Peptic Ulcer Patients

Further study details as provided by Francis KL Chan, Chinese University of Hong Kong:

Primary Outcome Measures:
  • Recurrent ulcer bleeding [ Time Frame: During the observation period ]
    Hematemesis or melena documented by the admitting physician, or a decrease in the hemoglobin level of at least 2 g/dL, with ulcers or bleeding erosions confirmed on endoscopy.

Secondary Outcome Measures:
  • All-cause mortality [ Time Frame: During the observation period ]
    The secondary endpoint is recurrent lower gastrointestinal (GI) bleeding, which was defined as recurrent overt bleeding (melena or hematochezia without an upper GI source) or a drop in hemoglobin >2 g/dL, without an upper GI source or other non-GI causes of anemia. We excluded hemorrhoidal bleeding and colorectal cancer as lower GI outcomes.

Enrollment: 391
Study Start Date: August 2002
Study Completion Date: July 2009
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Non NSAID non-Hp
Patient of history of peptic ulcer bleeding with Hp-ve and without prior history of taking NSAID or Aspirin within 30 days
Helicobacter pylori +ve
Patient with Hp+ve at peptic ulcer bleeding

Detailed Description:
Non-steroidal Anti-inflammatory Drugs (NSAID), Non-Helicobacter pylori (HP) bleeding peptic ulcers are relatively common in the West (11%-44%). It is uncommon in Hong Kong (4%). Significant number of these patients with non-NSAID, non-Hp bleeding ulcers had co-morbid illness and many had life-threatening conditions. Our recent study showed that there is an increasing incidence of non-steroidal anti-inflammatory drugs (NSAID), non-Helicobacter pylori (Hp) bleeding peptic ulcers. There is no datum on the natural course of these patients and this is our aim to have this observational study.
