More infoSpontaneous bacterial peritonitis (SBP) increases mortality, making it relevant to evaluate factors that negatively impact the outcome of patients who develop SBP. This study aimed to evaluate SBP as a risk factor in the outcome of patients with cirrhosis.
Materials and MethodsA retrospective and analytical study was conducted on patients with cirrhosis who developed SBP. The cause of cirrhosis, Child-Pugh score, Model for End-Stage Liver Disease (MELD) score, and MELD-Na score were evaluated. They were classified into early responders (ER) (more than 25% decrease in polymorphonuclear cells on the second day of effective antibiotic treatment), development of renal injury (RI), acute-on-chronic liver failure (ACLF), and 28-day mortality. Statistical analysis included evaluating the mortality rate using the Kaplan-Meier curve, log-rank test, considering significance at p 0.05. RI, ACLF, and non-early responders were independently compared.
ResultsA total of 79 patients were included, 40 males (50.63%). The most common etiology was alcohol-related in 39 cases (49.36%), and Child-Pugh class C was observed in 67 cases (84.81%). Cephalosporins were used in 66 cases (83.54%), and carbapenems in 13 cases (16.45%). There were 6 deaths among early responders and 29 deaths among non-early responders, with a mean survival of 25.76 days for early responders versus 9.78 days for non-early responders, p < 0.001 (fig1). There were 2 deaths without ACLF and 33 deaths with ACLF, with a mean survival of 26.93 days without ACLF versus 14.6 days with ACLF, p < 0.001. There were 3 deaths without renal injury and 32 deaths with RI, with a mean survival of 25.65 days without RI versus 16.17 days with RI, p < 0.001.
ConclusionsSBP is associated with a high mortality rate. However, treatment response, the presence of ACLF, and RI have a significant impact on patient survival.
