Abstract

PURPOSE
Vibrio vulnificus, one of the most invasive and rapidly fatal human pathogens known is a free-living inhabitant of estuarine and marine environments throughout the world. Vibrio septicemia usually present with a sudden onset of fever, chills, vomiting, diarrhea, abdominal pain, pain in the extremities, and cutaneous lesions. There are many microbiologic studies of V. vulnificus, but few clinical and prognostic studies are reported. We performed a study in 81 clinically suspected V. vulnificus cases to analyze the clinical characteristics of and the prognosis for V. vulnificus septicemia.
METHODS
The study included 81 clinically suspected cases V. vulnificus septicemia at the emergency department from 1997 to 2003. We retrospectively analyzed the clinical features and the laboratory data, and measured the simplified acute physiologic score (SAPS II).
RESULTS
The overall fatality was 39.5%. The monthly incidence was high in July and August. Almost all cases were primary septicemia (92.6%). Many patients had underlying disease; such as liver disease (66.6%), and diabetes mellitus (18.5%). Alcohol drinking habits were observed in 61.7% of the cases. There were significant difference between non-survivors and survivors in the extent of skin manifestations, respiration rate, leukocyte count, platelet count, albumin, PT, PTT, creatinine, pH, HCO(3-), and SAPS II.
CONCLUSION
The platelet count, PT, PTT, creatinine, pH, H CO3-, the leukocyte count, albumin, SAPS II, and the extent of skin manifestations can be used as severity indicators in V. vulnificus septicemia. Especially, the SAPS II on hospital day 2 and the extent of skin manifestations can be used as prognostic factors.
