Ryu, Yu, Suh, Kim, Ko, Park, and Cho: A Case of Community-Acquired Acinetobacter Meningitis

Abstract

Acinetobacter baumannii infections have become significant pathogen in hospitalized patients, especially in the intensive care unit setting. Community-acquired Acinetobacter meningitis in adults is a very rare infection of the central nervous system. Most community-acquired Acinetobacter infections have been reported from countries with a tropical or subtropical climate. Acinetobacter infections mainly affect patients with some form of comorbidity and are also associated with heavy smoking and excess alcohol consumption. In our case, a 62-year-old male patient with DM, hypertension, and excess alcohol consumption developed meningitis. Bulging membrane and inflammation were observed in the right ear. A. baumannii meningitis was confirmed by blood, CSF, and ear discharge culture. The patient was treated effectively with meropenem for 21 days. After antibiotic treatment, follow-up cultures of CSF, blood, and ear discharge showed a negative result, and the CSF cell profile was normalized. However, the patient died of recurrent pneumonia on hospital day 45. We report on a case of community-acquired Acinetobacter meningitis in an adult in Korea.

N/D, no data

aOne case of Asian Network for Surveillance of Resistant Pathogens (ANSORP) Study Group community-acquired pneumonia caused by gram-negative bacilli.

bThe patient was diagnosed as having multiple rib fractures and hemothorax, and was found dead in his house three days later. At autopsy, the pneumothorax test showed a positive result, due to pleural adhesion and cavitary abscess from A. baumannii pneumonia.
