Abstract Background Guidelines recommend use of fluoroquinolones and sulfamethoxazole-trimethoprim (SMX-TMP) for spontaneous bacterial peritonitis (SBP) prophylaxis based on data demonstrating a decrease in one-year incidence of SBP. Our institution frequently utilizes cefpodoxime for its favorable safety profile despite the lack of robust clinical experience. We sought to compare rates of breakthrough SBP with the use of cefpodoxime compared to previously reported incidence rates with the use of SMX-TMP and fluoroquinolones. Methods This is an IRB-approved, retrospective, single-center cohort analysis. The electronic medical record at the Hospital of the University of Pennsylvania was utilized to identify cirrhotic patients newly started on cefpodoxime for SBP prophylaxis from March 1, 2016, to December 31, 2020. The primary endpoint was the incidence of breakthrough infections within 1 year in patients who received cefpodoxime for primary or secondary SBP prophylaxis. Secondary endpoints included 1-year all-cause mortality and any microbiologic data from suspected or confirmed SBP during the study timeframe. Descriptive statistics were utilized to analyze baseline characteristics and collected data points. Results Overall, 90 patients met inclusion criteria within our timeframe. The study population consisted of mostly men (65.6%) with a mean age of 59 years. The majority of patients were taking cefpodoxime for primary prophylaxis (66.7%). A large proportion of the patients...
