Abstract:
Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III. generation cephalosporin. Nosocomial spontaneous bacterial peritonitis often caused by Gram-positive bacteria and multi-resistant pathogens can also be expected thus carbapenem should be the choice of the empiric treatment. Antibiotic prophylaxis should be considered. Norfloxacin is used most commonly, but changes are expected due to increase in quinolone resistance. As a primary prophylaxis, a short-term antibiotic treatment is recommended after gastrointestinal bleeding for 5 days, while long-term prophylaxis is for patients with low ascites protein, and advanced disease (400 mg/day). Secondary prophylaxis is recommended for all patients recovered from spontaneous bacterial peritonitis. Due to increasing antibiotic use of antibiotics prophylaxis is debated to some degree. Orv. Hetil., 2017, 158(2), 50-57.
Insights
Spontaneous bacterial peritonitis (SBP) in cirrhotic patients is diagnosed by high white blood cell counts in ascites fluid. Treatment varies from oral antibiotics for stable patients to intravenous options for severe cases, with prophylaxis strategies evolving due to resistance.
Area of Science:
- Hepatology
- Infectious Diseases
- Gastroenterology
Background:
- Spontaneous bacterial peritonitis (SBP) is a common complication in cirrhotic patients with ascites.
- Intestinal translocation of pathogens leads to SBP, with diagnosis based on elevated ascitic fluid polymorphonuclear leukocyte count (>0.25 G/L).
- Ascites cultures are frequently negative, limiting antibiotic sensitivity data.
Purpose of the Study:
- To review diagnostic criteria for SBP.
- To outline current and evolving treatment strategies for SBP.
- To discuss antibiotic prophylaxis protocols for SBP in cirrhotic patients.
Main Methods:
- Literature review of diagnostic and therapeutic approaches to SBP.
- Analysis of antibiotic choices based on patient stability and pathogen resistance.
- Evaluation of primary and secondary antibiotic prophylaxis guidelines.
Main Results:
- Empiric treatment for SBP includes ciprofloxacin or amoxicillin/clavulanic acid for stable patients, and third-generation cephalosporins for severe cases.
- Nosocomial SBP may require carbapenems due to multi-resistant pathogens.
- Norfloxacin is common for prophylaxis, but quinolone resistance necessitates alternative strategies.
Conclusions:
- Antibiotic prophylaxis for SBP is crucial but debated due to rising resistance.
- Primary prophylaxis involves short-term treatment post-GI bleed or long-term for advanced disease.
- Secondary prophylaxis is recommended for all SBP survivors, though evolving resistance patterns require ongoing reassessment.
