The complex interaction between H. pylori and NSAIDs implies that it is over simplistic to conclude that their relationship is independent, synergistic, or antagonistic without considering the influence of other factors. Factors such as previous exposure to NSAIDs, a history of ulcer complication, concurrent use of acid-suppressant therapy, and the difference between NSAIDs and low-dose aspirin all affect the outcome. Several recommendations can be made with regard to the indications of H. pylori eradication for patients requiring NSAIDs. First, patients taking NSAIDs who have ulcers or previous ulcer disease should be tested for the bacterium, and it should be eradicated if present because it is impossible to determine whether the ulcers are caused by H. pylori or NSAIDs or both. Antiulcer drugs should be prescribed to prevent ulcer recurrence for patients who continue to require NSAIDs. Although the efficacy of omeprazole is enhanced by H. pylori infection, it is not justified to leave a pathogen in the stomach in exchange for a modest therapeutic gain. Second, for patients who take low-dose aspirin, eradication of H. pylori substantially reduces the risk of ulcer bleeding. It is advisable that patients taking low-dose aspirin who are at risk of ulcer bleeding should be tested for H. pylori and treated for it if the infection is found. Third, for patients who are about to start NSAIDs, screen-and-treat H. pylori has the potential of reducing the ulcer risk at an affordable incremental cost. It might be argued that any interaction between H. pylori and NSAIDs would become irrelevant in the era of COX-2-selective NSAIDs. Even among patients who are receiving a COX-2-selective NSAID, however, a large-scale study showed that the ulcer risk is significantly higher in H. pylori-positive patients than in uninfected patients. This finding suggests that the relative importance of H. pylori in ulcer development might increase with a reduced toxicity of COX-2-selective NSAIDs. With an increasing use of low-dose aspirin for cardiovascular prophylaxis, the problem of aspirin-related ulcer disease is expected to rise. Given the significant role of H. pylori in the latter condition, screen-and-treat H. pylori might be a useful strategy for the prevention of ulcer complications in high-risk patients receiving low-dose aspirin in the future.
