    Abstract:
    BACKGROUND/AIMS: Bleeding from esophagogastric varices is a life-threatening complication of chronic liver disease. As compared with esophageal varices (EV), the risk factors for bleeding from gastric varices remain unclear. This study examined interactions between anti-ulcer drugs and non-steroidal anti-inflammatory drugs (NSAIDs) as related to bleeding esophagogastric varices in cirrhotic patients. METHODOLOGY: Eighty-eight cirrhotic patients with an initial episode of bleeding esophagogastric varices who had not received prior treatment studied. The patients were divided 3 groups: 58 with bleeding from EV, 13 with bleeding from cardiac varices (CV), and 17 with bleeding from cardiofundic or fundic varices (FV). The use of "standard" NSAIDs on 4 or more of the last 7 days before the initial episode of bleeding was defined as "regular" use; all other use was considered "occasional". RESULTS: The number of anti-ulcer drug users was 16 (27.6%) in the EV group, 4 (30.8%) in the CV group, and 5 (29.4%) in the FV group. The number of NSAID users was 9 (15.5%) in the EV group, 4 (30.8%) in the CV group, and 11 (64.7%) in the FV group. The proportion of NSAID users was significantly higher in the FV group than in the EV group (p < 0.0001). All 16 users of anti-ulcer drugs who were nonusers of NSAIDs had varices with red color signs. All NSAID users had used NSAIDs orally within a day before the initial episode of bleeding. All "regular" NSAID users were nonusers of anti-ulcer drugs. All anti-ulcer drug users without red color signs were "occasional" NSAID users. CONCLUSIONS: "Occasional" oral NSAID use is an important step leading to variceal hemorrhage, especially in FV, even if the mucosa is protected by anti-ulcer drugs. The ability to use NSAIDs for several days without variceal bleeding in some patients with esophagogastric varices who are concurrently receiving anti-ulcer drugs suggests that such drugs might protect the esophagogastric mucosa.
