Clinical Insights into Brucella Peritonitis: A Comprehensive Analysis of Four Cases.

ABSTRACT

INTRODUCTION: Brucellosis, a globally distributed zoonotic disease, exhibits diverse clinical manifestations, with Brucella peritonitis being a rare but consequential complication. METHODS: Analyzing the medical records of four patients with Brucella peritonitis admitted to the First People's Hospital of Kashi Region from January 2022 to November 2023. A retrospective approach was used to analyze the general data, epidemiological history, clinical features, laboratory tests, and efficacy. All four patients with Brucella peritonitis were farmers. RESULTS: All of them were combined with decompensated stage of liver cirrhosis. The main manifestations were poor appetite, fatigue, bloating. Two patients were accompanied by moderate-high fever. All patients presented with mildly elevated C-reactive protein and procalcitonin < 0.25ng/ml. Brucella was cultured from blood in 2 cases, from pleural fluid in 1 case, and from ascitic fluid in another case. All patients had moderate-to-large amounts of ascites with elevated leukocytes in the ascites, predominantly mononuclear cells. Symptoms of the above patients were reduced or disappeared after effective anti-infection. CONCLUSION: When patients with decompensated cirrhosis present with exudative ascites dominated by elevated mononuclear cells, the possibility of Brucella peritonitis should also be considered in areas where brucellosis is endemic.
