Q fever is a worldwide-occurring zoonosis caused by Coxiella burnetii. There are various clinical manifestations of acute Q fever, of which acute cholecystitis is a very rare clinical presentation. This study reports seven cases of acute cholecystitis associated with Coxiella burnetii and reviews two other cases from the literature. All patients were admitted to hospital for fever and abdominal pain in the right upper quadrant. Abdominal echography showed a distended gallbladder with biliary sludge without concrements in eight cases and with a single stone in one case. Diagnosis was made by specific serological investigation (microimmunofluorescence assay) for Coxiella burnetii. All nine patients were cured, six after laparoscopic cholecystectomy and three with antibiotics only. Histological examination of the gallbladders showed inflammation in five cases, although Coxiella burnetii was not detected by immunohistochemistry. The results show that laboratory investigations in patients admitted to hospital for symptoms consistent with acute acalculous cholecystitis should include a systematic search for Coxiella burnetii.

PMID:Acute acalculous cholecystitis associated with Q fever: report of seven cases and review of the literature. 1268 14

Acute acalculous cholecystitis is a very rare clinical presentation of Q fever. We report the case of a 38-year-old man who presented with fever associated with elevation of liver enzyme levels and thickening of the gallbladder wall on abdominal ultrasonography and who was initially diagnosed with acute acalculous cholecystitis. Due to the persistence of fever and transaminase elevation despite antibiotic treatment, a liver biopsy was performed. Characteristic "doughnut" epithelioid granulomas were observed, suggesting a diagnosis of granulomatous hepatitis caused by Q fever, which was confirmed by serological methods. Treatment with doxycycline was commenced and the patient subsequently showed rapid clinical improvement, with disappearance of fever and normalization of liver enzyme levels. We review 8 cases of acute cholecystitis associated with Q fever published in the literature and stress the importance of liver biopsy in the etiological diagnosis of patients with prolonged fever and abnormal liver function tests.

Q fever is an emerging infectious disease among US soldiers serving in Iraq. Three patients have had atypical manifestations, including 2 patients with acute cholecystitis and 1 patient with acute respiratory distress syndrome. Providers must be aware of Q fever's signs and symptoms to avoid delays in treatment.
