Infection is a common complication and leading cause of death in liver cirrhosis patients. In recent years, people gradually recognize the vital impact of infection, especially spontaneous bacterial peritonitis, on the course and prognosis of liver cirrhosis patients. Timely and effective empiric antibiotic therapy is particularly critical for the treatment of liver cirrhosis patients with bacterial infection. However, due to the spread of multidrug resistant bacteria and extensively drug-resistant bacteria, infection in cirrhosis has also become a difficult problem. At the same time, we have a clearer understanding on the pathogenesis of infection in cirrhosis. Novel therapeutic methods, such as intestinal microecological intervention and immunoregulatory therapy, have also become research hotspots recently. Establishing an effective treatment plan for liver cirrhosis patients with bacterial infections is the key to improve the survival rate and quality of life of these patients.
