Three cases of fulminant cellulitis caused by non-O1, non-O139 Vibrio cholerae in Southern Finland

Abstract

Background: Non-O1, non-O139 Vibrio cholerae is endemic in temperate waters. Most often encountered as the pathogen in transient gastroenteritis, it can also cause severe soft tissue infections. While normally a rare pathogen in Finland, we observed seven cases of non-O1, non-O139 V. cholerae infections in Helsinki University Hospital during the hot summer of 2018. Here we present three of these cases with fulminant V. cholerae cellulitis in detail.

Methods: Patients with tissue culture positive soft tissue infections between 2017 and 2019 were identified using a local laboratory database. Patients with severe infections requiring surgical revision were included in this series.

Results: Three patients with tissue culture positive non-O1, non-O139 V. cholerae cellulitis were identified. All were treated in the summer of 2018 for fulminant lower leg cellulitis. Two patients were febrile and hemodynamically unstable at presentation. One had septicaemia. Surgical revisions were done within the first week of admission, and defects covered with partial-thickness skin grafts several weeks later. Antibiotic treatment varied and continued until the wounds were healed, between one and over two months in total.
