MTE #28: Spontaneous Bacterial Peritonitis (Ticketed)
Primary and secondary prophylaxis for spontaneous bacterial peritonitis (SBP) has been a cornerstone of cirrhosis management for decades, informed by early studies suggesting a survival benefit and reduced infectious complications. As a result, long-term antibiotic prophylaxis has become routine practice for many persons with advanced liver disease. Emerging evidence, however, is challenging this paradigm. Recent randomized controlled trials have failed to demonstrate clear survival benefits in selected populations while analyses of large retrospective cohorts raise concerns regarding limited effectiveness in real-world settings. Further, increasing antibiotic resistance, shifts in bacterial epidemiology, and unintended consequences of prolonged antibiotic exposure have brought renewed scrutiny to SBP prophylaxis strategies.
Experts critically review the evolving evidence base for SBP prophylaxis, examine discrepancies between historical assumptions and contemporary data, and explore how new findings should inform patient selection, risk stratification, and future clinical guidelines.
