[Current standard of antibiotic prophylaxis in esophageal varices bleeding in Germany]

Antibiotic prophylaxis in patients with liver cirrhosis and upper gastrointestinal bleeding significantly reduces the risk of concomitant bacterial infections and early mortality. The goal of our study was to determine the current status of antibiotic prophylaxis in departments of gastroenterology in Germany.

Representatives of gastroenterology departments were asked to provide data about indication for, and duration of, antibiotic prophylaxis and choice of antibiotic in esophageal varices bleeding in patients with liver cirrhosis.

326 of 779 contacted departments of gastroenterology participated in the study. Whereas antibiotic prophylaxis is used in 98.5 % (n = 321/326) of cases, it is used only in 7.1 % (n = 23/322) depending on the Child-Pugh-Score. In 19.4 % (n = 62/320), a prophylaxis is given even to patients with an elective banding of esophageal varices without bleeding. Third generation cephalosporins are used most frequently (66.5 %; n = 248/373) followed by fluoroquinolones (19.9 %; n = 74/373). The duration of prophylaxis was 3 days in most cases (32.3 %; n = 104/322), 1 day in 9.3 % (n = 30/322) and 7 days as recommended by German treatment guidelines in 24.8 % (n = 80/322). A standard of procedure (SOP) for antibiotic prophylaxis in esophageal varices bleeding is available in 45.1 % (n = 147/326).

Our study shows that the applied standards for antibiotic prophylaxis in esophageal varices bleeding varies greatly in Germany. Future studies about the necessary duration of prophylaxis and its dependency from the Child-Pugh-Score are needed so that unnecessary antibiotic prescriptions can be avoided. The avoidance of antibiotic prophylaxis in elective banding of non-bleeding esophageal varices, which is not recommended by guidelines and was used by about 20 % of participants in our study, can already reduce antibiotic use.
