什么是暴发性紫癜?
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. This is called disseminated intravascular coagulation (DIC).
DIC causes your body to create too many blood clots, followed by periods of bleeding. This clotting and bleeding can interfere with blood vessels bringing oxygen to your tissues. If your tissues and organs can’t get enough oxygen, they will shut down.
暴发性紫癜的原因?
暴发性紫癜有多种原因. 它们是以下细菌感染：
脑膜炎球菌: The bacteria neisseria meningitidis that causes meningococcal meningitis. This is an infection of the thin lining that surrounds the brain and spinal cord.
革兰氏阴性杆菌或革兰氏阴性细菌：引起肺炎的细菌, 血液感染, 伤口或手术部位感染, 和脑膜炎.
葡萄球菌：皮肤或鼻子里的细菌. 大多数时候, these bacteria cause no problems or minor skin infections (called staph infections). But staph infections can turn deadly if the bacteria invade deeper into your body or into your bloodstream.
链球菌一种引起链球菌感染的细菌, 比如链球菌性喉炎, 猩红热, 脓疱病, 和其他人.
立克次氏体生物: A type of bacteria found in ticks, lice, fleas, mites, chiggers, and mammals. They can cause Rocky Mountain spotted fever, rickettsialpox, and other fevers.
While purpura fulminans is rare, it is important that you get treatment as quickly as possible.
暴发性紫癜的症状
With purpura fulminans, your skin begins dying in the dermal layer. This causes a rash that can rapidly progress to blood filled blisters.
This process generally affects the skin and tissues—not the muscle. This symptom is an early sign of the disease process.
Doctors use a skin biopsy to diagnose purpura fulminans. A skin biopsy removes a small section of skin cells to examine them in a laboratory. If the specialists determine you have purpura fulminans, they will immediately start treatment.
