Cryptogenic acute cholangitis--association with toxic shock syndrome

Area of Science:

• Hepatology
• Gastroenterology
• Pathology

Background:

• Cryptogenic acute cholangitis is a severe biliary tract disease.
• Toxic shock syndrome (TSS) can present with jaundice and hyperbilirubinemia.
• The pathogenesis of cryptogenic cholangitis in the context of TSS is not well understood.

Purpose of the Study:

• To report the clinical and pathologic findings of eight patients with cryptogenic acute cholangitis.
• To investigate the potential link between acute cholangitis and TSS.
• To explore the pathogenetic mechanisms of cryptogenic acute cholangitis.

Main Methods:

• Case series review of eight patients with cryptogenic acute cholangitis.
• Clinical and pathologic data analysis, including postmortem examination.
• Bacteriologic cultures of blood and postmortem tissues.

Main Results:

• Six of eight patients presented with TSS; mortality was high (7/8).
• No patients had pre-existing liver or gallbladder disease; biliary and pancreatic systems were grossly normal.
• Histologic findings revealed acute cholangitis with minimal cholestasis, alongside systemic organ changes. Blood cultures were largely negative; Staphylococcus aureus was isolated in two postmortem samples.

Conclusions:

• Cryptogenic acute cholangitis may contribute to jaundice in TSS patients.
• Circulating toxins, rather than bacterial infection, are implicated in the pathogenetic mechanism of bile duct damage.
• Further research is needed to elucidate the role of toxins in acute cholangitis.
