Abstract:
Spontaneous bacterial peritonitis (SBP) is defined as bacterial infections that occur in patients with cirrhosis and ascites without any significant intraperitoneal infection, accounting for approximately 10-30% of bacterial infections in hospitalized patients. SBP develops in patients with liver cirrhosis because bacterial translocations are increased by changes in the intestinal bacteria and mucosal barriers. In addition, the decreased host immune response cannot remove the bacteria and their products. The most common cause of SBP is Gram-negative bacteria, such as Escherichia coli and Klebsiella species, and infections by Gram-positive bacteria are increasing. SBP is diagnosed by the presence of >250 polymorphonuclear leukocyte/mm3 in ascites after paracentesis. If SBP is diagnosed, empirical antibiotic therapy should be started immediately. Empirical antibiotic treatment should distinguish between community acquired infections and nosocomial infections. Cirrhotic patients with gastrointestinal bleeding or low ascitic protein concentrations should consider primary prevention and those who recover from SBP should consider secondary prevention. This review describes the pathophysiology, diagnosis, treatment, and prevention of SBP.
Insights
Spontaneous bacterial peritonitis (SBP) is a serious infection in cirrhosis patients. Early diagnosis and prompt antibiotic treatment are crucial for managing SBP and preventing complications.
Area of Science:
- Hepatology
- Infectious Diseases
- Gastroenterology
Background:
- Spontaneous bacterial peritonitis (SBP) affects 10-30% of hospitalized patients with cirrhosis and ascites.
- Bacterial translocation and impaired immune response contribute to SBP development in liver cirrhosis.
- Gram-negative bacteria are common culprits, but Gram-positive infections are rising.
Purpose of the Study:
- To review the pathophysiology, diagnosis, treatment, and prevention strategies for spontaneous bacterial peritonitis.
- To highlight the importance of timely intervention in managing SBP in cirrhotic patients.
Main Methods:
- Literature review of spontaneous bacterial peritonitis.
- Analysis of diagnostic criteria and treatment guidelines for SBP.
- Examination of primary and secondary prevention strategies for SBP.
Main Results:
- SBP diagnosis relies on ascitic fluid analysis showing >250 polymorphonuclear leukocytes/mm³.
- Immediate empirical antibiotic therapy is essential upon SBP diagnosis.
- Prevention strategies are recommended for high-risk cirrhotic patients.
Conclusions:
- Effective management of SBP requires prompt diagnosis and appropriate antibiotic treatment.
- Primary and secondary prevention are vital for reducing SBP incidence and recurrence in cirrhotic patients.
- Understanding SBP pathophysiology aids in developing targeted interventions.
