Haemophilus influenzae typically causes illness and infection in the paediatric population. We report a case of a 53-year-old man who developed invasive non-typeable H. influenzae infection associated with purpura fulminans and multiorgan failure. On review of the literature, this is the first reported case of non-typeable H. influenzae causing purpura fulminans. The patient was treated with intravenous ceftriaxone 2 g/day and was eventually discharged from the hospital almost 2 months after admission. We discuss the role that infection/sepsis plays in disturbances to the coagulation cascade leading to purpura fulminans and the virulence factors that make non-typeable H. influenzae unique. Finally, we review other cases of H. influenzae associated with purpura fulminans and discuss the similarities with our case.
