Purpura fulminans may also lead to severe large vessel venous thrombosis if untreated in its early stages.Purpura fulminans secondary to severe infection is self-limiting. In cases of homozygous protein C deficiency, episodes of purpura fulminans and other thrombotic events are recurrent. Moreover, infant survival due to maintenance replacement therapy is often associated with intellectual disability or visual impairment. For post-infection purpura fulminans, new lesions will occur while neutralising autoantibodies are present (1–2 weeks after presentation).A multi-disciplinary care team is usually required for rehabilitation after purpura fulminans. Epidemiology
Purpura fulminans is rare and most commonly occurs in babies and small children but can also be a rare manifestation in adults when it is associated with severe infections. For example, Meningococcal septicaemia is complicated by purpura fulminans in 10–20% of cases among children. Purpura fulminans associated with congenital (inherited) protein C deficiency occurs in 1:500,000–1,000,000 live births. Research
Due to the rarity of purpura fulminans and its occurrence in vulnerable patient groups like children research on the condition is very limited and evidence based knowledge is scarce. History
Purpura fulminans was first described by Guelliot in 1884. References
