Definition Hypersensitivity vasculitis is an extreme reaction to a drug, infection, or foreign substance. It leads to inflammation and damage to blood vessels, mainly in the skin. The term is not used much currently because more specific names are considered more precise Sometimes, vasculitis causes an aneurysm — a bulge or ballooning in the wall of a blood vessel. This bulge may need surgery to reduce the risk of it rupturing. Blocked arteries also may require surgical treatment to restore blood flow to the affected area. Request an Appointment at Mayo Clini Overview Vasculitis involves inflammation of the blood vessels. The inflammation can cause the walls of the blood vessels to thicken, which reduces the width of the passageway through the vessel. If blood flow is restricted, it can result in organ and tissue damage Hypersensitivity vasculitis is an extreme reaction to a drug, infection, or foreign substance. It leads to inflammation and damage to blood vessels, primarily in the skin Hypersensitivity ('allergic') vasculitis, which is less used now, is a generic term for small vessel cutaneous vasculitis affecting capillaries, venules, or arterioles. It includes mainly.

Hypersensitivity (Allergic) Vasculitis: Symptoms

  1. al pain, swollen and painful joints, and blood in urine. Most common in children between 2 and 11 years old
  2. Hypersensitivity vasculitis (HV, cutaneous small-vessel vasculitis, cutaneous leukocytoclastic vasculitis, cutaneous leukocytoclastic angiitis) is a term used to denote a leukocytoclastic vasculitis involving primarily the skin, and in most cases, secondary to a drug ingestion or infectious process
  3. Abstract. We describe clinical and pathological features of kidney and skin involvement in a patient with hypersensitivity vasculitis associated with dapsone. Although visceral damage occurs rarely, similar skin and kidney histopathologic and immunohistochemical findings indicate that this organ is a target for type IV cell-mediated dapsone.
  4. Hypersensitivity vasculitis or allergic vasculitis does not have any cure as such. The aim of treatment is to manage and alleviate the patient's symptoms.If a medication is causing the hypersensitivity vasculitis or allergic vasculitis, the patient is told to stop taking that medication after appropriate doctor's recommendation
  5. Hypersensitivity vasculitis is an extreme reaction to a drug, infection, or foreign substance that leads to inflammation and damage to blood vessels of the skin. Signs and symptoms may include purple-colored spots and patches on the skin; skin lesions on the legs, buttocks,.
  6. Allopurinol hypersensitivity syndrome (AHS) is a spectrum of reactions that includes SJS and TEN, and also systemic disease with eosinophilia, vasculitis, rash, and major end-organ disease. There is a reported mortality of 20% to 25% for AHS

  3. Leukocytoclastic vasculitis is also referred as hypersensitivity vasculitis or hypersensitivity angiitis.The disease is presented by small spots of discolorations known as purpura. The spot is caused by the bleeding beneath the skin which in turn causes the reddish or purplish discoloration of the skin
  4. In type III hypersensitivity reactions, the persistence of antigen from chronic infection or autoimmune diseases can develop complex immune diseases, including vasculitis and glomerulonephritis. Penicillin as an antigen can produce any hypersensitivity reaction, e.g., anaphylactic shock, hemolytic anemia, and serum sickness

Our immune system works continuously to keep us healthy and protect us against bacteria, viruses, and other germs.Sometimes, however, this system becomes too sensitive, causing hypersensitivity reactions that can be harmful or even deadly. These reactions are the result of exposure to some type of foreign antigen either on or in the body vasculitis [vas″ku-li´tis] inflammation of a blood or lymph vessel; see arteritis, lymphangitis, and phlebitis. Called also angiitis. Churg-Strauss vasculitis churg-strauss syndrome. hypersensitivity vasculitis a group of systemic necrotizing vasculitides thought to represent hypersensitivity to an antigenic stimulus, such as a drug, infectious agent. Hypersensitivity vasculitis, as traditionally classified , is best encompassed under the broad categories of either single organ vasculitis and named as cutaneous arteritis or cutaneous leukocytoclastic angiitis (eg, skin limited and without glomerulonephritis) or alternatively under the category of vasculitis associated with probable. HSP may be misdiagnosed as another form of vasculitis - most commonly hypersensitivity vasculitis - because of the frequent failure to perform direct immunofluorescence (DIF) testing on skin biopsy and the consequent failure to detect IgA. Treatment and Course of Henoch-Schönlein Purpura Hypersensitivity vasculitis (HV) is a term often used to describe many different conditions. Most commonly the term is applied to a vasculitic skin rash caused by sensitivity to a drug although it may be seen in association with several other conditions. Most commonly only the skin is affected although the bowels, kidneys and joints may also be.

However, hypersensitivity vasculitis is sometimes used to refer to CSVV caused by a known drug or infection. Symptoms and Signs of Cutaneous Vasculitis Patients may present with skin symptoms such as lesions, including palpable purpura, petechiae, urticaria, ulcers, livedo reticularis, and nodules Hypersensitivity vasculitis (HV), or cutaneous vasculitis, is characterized by inflammation of the small vessels of the skin with resultant ischemia to the distally supplied areas. To our knowledge, this is the first reported case of presumed hypersensitivity vasculitis following Prolastin infusion

Hypersensitivity vasculitis. Hypersensitivity vasculitis results in palpable purpura with or without systemic involvement (kidney, muscles, joints, GI tract, peripheral nerves). It is thought to be due to the deposition of circulating immune complexes, and is associated with the release of vasoactive amines and complement activation Hypersensitivity vasculitis is known by other names. It is also called cutaneous vasculitis, allergic vasculitis and leukocytoclastic vasculitis. As already alluded to earlier, hypersensitivity vasculitis is caused by an allergic reaction or hypersensitivity to a drug or another foreign substance. However, even with a complete medical history. Vasculitis is the inflammation (swelling) of the body's blood vessels. The condition occurs if your immune system attacks your blood vessels by mistake. Vasculitis can affect very small blood vessels (capillaries), medium-size blood vessels, or large blood vessels such as the aorta (the main blood vessel that leaves the heart) Overview. Hypersensitivity vasculitis is inflammation of the vessel wall which is usually due to a hypersensitivity reaction to a known drug, auto-antigens or infectious agents such as bacteria.. Pathophysiology. Immune complexes lodge in the vessel wall, attracting polymorphonuclear leukocytes who in turn release tissue-degrading substances leading to an inflammatory process

However, in most cases, vasculitis is thought to be due to disturbances of the body's immune system. Some forms of vasculitis may be due to allergic reactions or hypersensitivity to certain medications such as sulfur drugs, penicillin, propylthiouracil, other drugs, toxins, or other inhaled environmental irritants Hypersensitivity vasculitis may present clinically as cutaneous disease only or it may be a cutaneous manifestation of systemic disease. The internal organs most commonly affected in hypersensitivity vasculitis are the joints, gastrointestinal tract, and kidneys.
