Background
Vibrio vulnificus is typically present in seawater, fish, and shellfish, and is known to cause severe sepsis, particularly in patients with liver diseases such as cirrhosis. V. vulnificus is one of the most dangerous waterborne pathogens, and infection mainly occurs in western Japan during the summer, with an increased fatality rate. Herein, we report the case of a patient with primary biliary cholangitis and sepsis caused by V. vulnificus infection sustained through shrimp shelling.
Case presentation
An 82-year-old Japanese Asian woman with no medical history or underlying disease developed redness, swelling, and pain, which extended from the right fingers to the upper arm. A diagnosis of sepsis due to cellulitis was made. Blood culture detected V. vulnificus; thus, minocycline was administered in addition to meropenem. The disease course was uneventful, and the patient was discharged on day 28 of hospitalization. Symptoms in the right upper arm developed 1 day after the patient shelled a large number of shrimp; therefore, the infection route was assumed to be through wounds sustained during shrimp shelling. We suspected liver disease and measured serum anti-mitochondrial M2 antibody levels, leading to the diagnosis of primary biliary cholangitis.
Conclusions
As in this case, small wounds caused by handling fish and shrimp are a potential source of infection. Patients with severe V. vulnificus infection should be thoroughly assessed for the presence of liver diseases such as primary biliary cholangitis.
