title: [Importance of age and other risk factors in NSAID-induced gastropathy].
abstract: OBJECTIVE
  It is clinically important to analyze the risk factors of NSAID-induced gastropathy because there could be no symptoms. Age is the most important risk factor according to previous reports. The aim of this study was to find risk factors of NSAID-induced gastropathy and to confirm the association between NSAID-induced gastropathy and age.
  
  
  METHODS
  We retrospectively assessed 300 patients who conducted an upper gastroscopy during the course of chronic NSAID treatment.
  
  
  RESULTS
  Median age of patients group is 51.4 +/- 12.2 years. In multivariate analysis, age and ulcer history are two significant risk factors. Median age is 46.7 +/- 10.7 years for the patients with nonspecific gastroscopic finding, 53.0 +/- 12.5 for those with erosion, 57.6 +/- 10.0 for those with ulcer, and 63.2 +/- 8.9 for those with hemorrhage. The proportion of ulcer patients is as follows: 6% in the patients of under 40 years old, 14.9% in patients of the 40s, 20% in patients of the 50s, 30.9% in patients of the 60s, 33.3% in patients over 70 years. The proportion of nonspecific findings is 62.2% in patients of the 40s, 37.8% in patients of the 50s, and 29% in patients over 60 years.
  
  
  CONCLUSIONS
  Age is the most important risk factor of the NSAID-induced gastrointestinal mucosal injury. A larger randomized prospective control study will be required in the future for more conclusive results.
