Abstract:
Spontaneous bacterial peritonitis (SBP) is a severe complication of cirrhosis, occurring in approximately 15 % of cirrhotic patients. The most common causative pathogens of SBP are Escherichia coli and Klebsiella pneumoniae. Although brucellosis can cause various complications, it is a rare cause of peritonitis. Herein, we report a case of a 30-year-old male with chronic hepatitis B who presented with fever, night sweats, weight loss, abdominal pain, and distension. Brucella spp. was isolated from blood and peritoneal fluid cultures. The patient fully recovered following six weeks of treatment with oral doxycycline (100 mg twice daily) and rifampicin (600 mg/day). No relapses or complications were observed during follow-up.
Insights
Brucellosis is a rare cause of spontaneous bacterial peritonitis (SBP) in cirrhotic patients. This case highlights successful treatment of Brucella-induced SBP with doxycycline and rifampicin.
Area of Science:
- Infectious Diseases
- Hepatology
- Microbiology
Background:
- Spontaneous bacterial peritonitis (SBP) is a serious complication in cirrhosis patients.
- Escherichia coli and Klebsiella pneumoniae are the most frequent pathogens causing SBP.
- Brucellosis is an uncommon etiology for peritonitis.
Observation:
- A 30-year-old male with chronic hepatitis B presented with symptoms suggestive of SBP.
- Blood and peritoneal fluid cultures identified Brucella species.
- The patient experienced fever, night sweats, weight loss, abdominal pain, and distension.
Findings:
- Brucella spp. was successfully isolated from blood and peritoneal fluid.
- The patient achieved full recovery after a six-week course of doxycycline and rifampicin.
- No recurrence or complications were noted during the follow-up period.
Implications:
- Brucellosis should be considered in the differential diagnosis of SBP, especially in endemic areas.
- Effective antibiotic regimens including doxycycline and rifampicin can successfully treat Brucella-induced SBP.
- This case underscores the importance of microbiological diagnosis for guiding appropriate therapy in complex cirrhotic patients.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
