Background Spontaneous bacterial peritonitis (SBP) is a common and potentially fatal complication of liver cirrhosis. This study aims to analyze the prevalence of SBP among liver cirrhotic patients according to geographical location and income level, and risk factors and outcomes of SBP. Methods A systematic search for articles describing prevalence, risk factors and outcomes of SBP was conducted. A single-arm meta-analysis was performed using generalized linear mix model (GLMM) with Clopper-Pearson intervals. Results 99 articles, comprising a total of 5,861,142 individuals with cirrhosis were included (IDDF2021-ABS-0019 Figure 1. Summary of Findings). Pooled prevalence of SBP was found to be 17.12% globally (CI: 13.63% - 21.30%), highest in Africa (68.20%; CI: 12.17% - 97.08%), and lowest in North America (10.81%; CI: 5.32% - 20.73%; IDDF2021-ABS-0019 Figure 2. Summary of SBP prevalence by region). The summary of the global prevalence is found in figure 1. Prevalence of community-acquired SBP was 6.05% (CI: 4.32% - 8.40%), and 11.11% (CI: 5.84% - 20.11%,) for healthcare-associated SBP. Antibiotic-resistant microorganisms were found in 11.51% (CI: 7.28% - 17.74%) of SBP patients. Of which, methicillin-resistant Staphylococcus aureus was most common (6.23%; CI: 3.83% – 9.97%), followed by extended-spectrum beta-lactamase producing organisms (6.19%; CI: 3.32% - 11.26%), and lastly vancomycin-resistant enterococci (1.91%; CI: 0.41% - 8.46%). A subgroup analysis was conducted to compare the rate of resistant SBP based on continent and summarized in figure 2. Subgroup analysis comparing prevalence, antibiotic resistance and outcomes between income groups. Conclusions SBP remains a frequent complication of liver cirrhosis worldwide. The drawn link between income level and SBP in liver cirrhosis may enable further insight on actions necessary to tackle the disease on a global scale. |
