Abstract | Background
Listeria monocytogenes is an uncommon but important cause of bacteremia and
meningitis in Hong Kong. Our aim is to study the local epidemiology, clinical
features, antibiotic susceptibility pattern and outcome of Listeriosis in Hong Kong.
Methods
A retrospective study was carried out in two local microbiology laboratories in Hong
Kong. All patients with positive Listeria monocytogenes isolates in any clinical
specimens over the past 10 years were included.
Results
A total of 31 patients with 41 Listeria monocytogenes isolates were identified in our
series. Fever was the most common presentation (80% of patients). There were 20
cases of bacteremia, 3 cases of meningitis and 3 cases of bacteremic meningitis. In
non-perinatal cases, most of the patients had underlying medical conditions. The most
common associated co-morbidity was underlying malignancy. The mortality of
Listeria monocytogenes infection was 24%. The stillbirth rate in pregnant women was
40%. 27% of patients were documented to have consumed dairy products or other
high-risk foods. There were 2 isolates intermediate sensitivity to penicillin while all
tested isolates were 100% sensitive to ampicillin, Septrin and vancomycin. Mortality
was not associated with appropriate antibiotic use, use of immunosuppressants or
advanced age.
Conclusions
Human Listeriosis is a rare but important infection in Hong Kong. It particularly
affects newborns, pregnant women and immunocompromised hosts, and carries a high
risk of mortality and stillbirth. |
