A rare case of hemolytic-uremic syndrome due to a Capnocytophaga canimorsus sepsis: Case report

TMA secondary to C canimorsus bacteremia is exceptionally rare (<20 cases reported). Because the organism grows slowly, clinicians should maintain a high index of suspicion in septic patients with recent dog exposure - especially when TMA is present on admission - and start appropriate empiric therapy while cultures are pending. Early distinction between primary thrombotic thrombocytopenic purpura/hemolytic-uremic syndrome and infection-associated TMA is essential to guide management.
