Other ethiologies are idiopathic forms or purpura neonatorum, which is marked by deficiency of Protein-C. PF is caused by micro-embolism of the vascular system, followed by quickly spreading necroses of skin and different organs.Modern concepts of intensive care treatment of the acute phase of this disease and early surgical intervention lead to a rising number of surviving patients requiring limb salvage.Aim of this study is to evaluate a possible lower morbidity and the grade of lower loss of function because of early surgical intervention.

Finally, we showed that this ADAM10-mediated shedding of EPCR induced by the meningococcal interaction with endothelial cells was responsible for an impaired activation of Protein C. This work unveils for the first time a direct link between meningococcal adhesion to endothelial cells and a severe dysregulation of coagulation, and potentially identifies new therapeutic targets for meningococcal purpura fulminans.

In this unselected cohort of paediatric patients with symptomatic TE the overall prevalence of PCD was 7·4%; 1·5% presented with neonatal purpura fulminans.

The authors describe a patient heterozygous for prothrombinG20210A who developed purpura fulminans and extensive venous thrombosis secondary to acquired protein S deficiency.
Here the authors report a case of patient with severe PS deficiency associated with the FVL mutation who has had purpura fulminans since the age of 10 days.
The interaction and the contribution of recently described mutations such as factor V Leiden and prothrombin G20210A to the development and progression of postinfectious purpura fulminans and venous thrombosis is not known.
We present 2 children from 2 unrelated Arab families with purpura fulminans who were double heterozygotes for factor V Leiden inherited from their fathers and protein S deficiency inherited from their mothers.
A male patient diagnosed with severe congenital protein C (PC) deficiency during the neonatal period was treated with long-term warfarin but frequently developed purpura fulminans and bleeding.
Protein C (PC) deficiency is a heritable or acquired risk factor for thrombophilia, with presentations varying from asymptomatic to venous thromboembolism to neonatal purpura fulminans, a life-threatening disorder.
Purpura fulminans (PF) is a neonatal presentation of homozygous or compound heterozygous protein C (PC) deficiency; infants who are diagnosed with it are determined to have a major defect in coagulation regulation which is associated with undetectable levels of PC.
This case highlights the course of PF due to acquired PC deficiency in a newborn treated with PC concentrate which is rarely described in the literature.
Sixteen newborns presented with PF (n = 11, 69%), intracranial thromboembolism and hemorrhage (n = 13, 81%), or both (n = 8, 50%), with most showing a plasma PC activity of <10%.
