Background: Vibrio species are an uncommon cause of necrotizing
fasciitis and primary septicemia, which are likely to occur in patients with
hepatic disease, diabetes mellitus, adrenal insufficiency, and
immunocompromised conditions. These organisms are found in warm sea waters and
are often present in raw oysters, shellfish, and other seafood. The purposes
of the present report were to describe a series of patients who had this
potentially lethal infection and to identify clinical features associated with
a poor prognosis.
Methods: We retrospectively reviewed the records of thirteen
patients (ten men and three women) who had necrotizing fasciitis and sepsis
caused by Vibrio species. All patients had a history of contact with seawater
or raw seafood. Eight patients had a hepatic disease such as hepatitis or
cirrhosis of the liver, three had diabetes mellitus (without hepatic disease),
and two had chronic renal or adrenal insufficiency (without hepatic
disease).
Results: Twelve patients underwent fasciotomy or limb amputation.
Five patients (38%) died within two to six days after admission, and eight
patients survived. Patients with a systolic blood pressure of =90 mm Hg and
leukopenia in the emergency room had a significantly higher mortality rate (p
< 0.05).
Conclusions: The diagnosis of Vibrio necrotizing fasciitis should be
suspected when a patient has the appropriate clinical findings and a history
of contact with seawater or raw seafood. The treatment should begin as early
as possible, essentially when the patient has symptoms of sepsis. Although
emergency fasciotomy or limb amputation did not reduce the mortality rate in
this series, we consider such operations to be an important aspect of
treatment.
Level of Evidence: Prognostic study, Level IV (case
