What causes purpura fulminans?
The most common cause of acute infectious purpura fulminans is meningococcus, though streptococci, varicella-zoster virus, Gram-negative bacilli, staphylococci, Rickettsia species, and measles virus have also been associated with this form of purpura fulminans.
Can purpura fulminans be cured?
Purpura fulminans with disseminated intravascular coagulation should be urgently treated with fresh frozen plasma (10–20 mL/kg every 8–12 hours) and/or protein C concentrate to replace pro-coagulant and anticoagulant plasma proteins that have been depleted by the disseminated intravascular coagulation process.
Are purpura fulminans fatal?
Purpura fulminans (PF) is a unique and devastating thrombotic disorder, often acute and fatal, that manifests as large irregular areas of blue-black cutaneous bleeding that rapidly progress to necrosis of superficial skin and deeper soft tissues.
What is Fulminans?
Purpura fulminans is a disorder where your skin bleeds and dies rapidly (skin necrosis). The bleeding is caused by blood clots in the dermal layer (skin layer under the top layer or epidermis). The blood vessels in your skin also collapse and the proteins that cause your blood to clot become overactive.
How common is purpura fulminans?
Each form of purpura fulminans has a different prevalence. The hereditary neonatal form with severe protein C deficiency occurs in about 1:1,000,000 live births. [2]Acute infectious purpura fulminans can be seen in up to 10% to 20% of patients who develop meningococcal septicemia.
What is meningococcal purpura fulminans?
Purpura fulminans is a cutaneous manifestation of disseminated intravascular coagulation. It presents as a purpuric rash and symmetric gangrene that often necessitates amputation. It can accompany infections with meningococcus, varicella, Staphylococcus aureus, streptococcus and Hemophilus influenzae.
How is purpura fulminans diagnosed?
Specific levels of antithrombin III, free protein C, and free and total protein S may help confirm the diagnosis especially in the neonatal form of the disease. Otherwise, the evaluation of patients with purpura fulminans mimics the evaluation of the underlying cause.
What causes meningococcal disease?
Meningococcal disease is caused by bacteria called Neisseria meningitidis. It can lead to serious blood infections. When the linings of the brain and spinal cord become infected, it is called meningitis. The disease strikes quickly and can have serious complications, including death.
Is HSP serious?

What are the signs of meningococcal?
Symptoms of meningococcal disease are non-specific but may include sudden onset of fever, headache, neck stiffness, joint pain, a rash of red-purple spots or bruises, dislike of bright lights nausea and vomiting. Not all of the symptoms may be present at once. Young children may have less specific symptoms.
Is HSP an autoimmune disease?
