Oedeme angioneurotique bradykinique

Morbidity and mortality from bradykinin-mediated BK angioedema AE are considerable. If the upper respiratory tract is involved, this is associated with emergency treatment and admission to the intensive care department. Laryngeal oedema and macroglossia are more common in patients presenting with an AE as an effect of taking converting enzyme inhibitors ACE inhibitors than in hereditary forms, where abdominal pain is more common.

Involvement of the larynx and the progressive nature of the oedema are risk factors for admission to hospital for an AE attack following a reaction to ACE inhibitors. Emergency-specific treatments primarily include a C1 inhibitor concentrate and icatibant. They must be administered as early as possible given that anti-allergy treatments are ineffective.

Specialist advice, including in the emergency department, appears to be required for the appropriate care of patients. Treatment of these patients was recently changed, with the development of links between doctors specialising in emergency medicine and referring physicians at the bradykinin-mediated angioedema reference centre.

An appropriate treatment pathway and multidisciplinary management are vital in providing the correct care for these patients, with a view to ensuring emergency-specific treatments are available.

It is most often characterised by an abrupt and short-lived swelling of the skin and mucous membranes. All parts of the body may be affected but swelling most often occurs around the eyes and lips.

In severe cases, the internal lining of the upper respiratory tract and intestines may also be affected. Angioedema Image provided by Dr Janjua. Angioedema and urticaria are very similar in many ways and can co-exist and overlap.

Urticaria occurs more commonly and is less severe than angioedema as it only affects the skin layers whereas angioedema affects the tissues beneath the skin subcutaneous tissue.

The main differences between urticaria and angioedema are shown in the following table. The causes of angioedema depend on the type of angioedema a patient has. Angioedema can be classified into at least four types, acute allergic angioedema, non-allergic drug reactions, idiopathic angioedema, hereditary angioedema HAE and acquired C1 inhibitor deficiency.

Whatever the cause of angioedema, the actual mechanism behind the swelling is the same in all cases. This same mechanism occurs in urticaria but just closer to the skin surface.

Symptoms and signs of angioedema may vary slightly between the different types of angioedema but in general, some or all of the following occur. Skin prick testing may be performed to try and identify any allergens.

Treatment of angioedema depends on the severity of the condition. In cases where the respiratory tract is involved the first priority is to secure the airway. Patients may need emergency hospital care and require intubation placement of a tube in the throat to keep the airway open. In many cases, the swelling is self-limiting and resolves spontaneously after a few hours or days.

In more severe cases where there is persistent swelling, itchiness or pain the following medications may be used. Chronic angioedema with chronic autoimmune or chronic idiopathic urticaria is often difficult to treat and response to medication variable.

The following treatment steps are recommended. Each step is added to the previous one if an inadequate response is obtained. Omalizumaban anti-IgE monoclonal antibodyhas been reported to be effective in some refractory cases of angioedema.

The goal of treatment for chronic angioedema is to reduce itch, swelling, tenderness and pain to a tolerable level to maintain function eg, at work, school, and during sleep.

Acute episodes of hereditary angioedema do not respond to adrenaline, antihistamine and corticosteroids. Most acute episodes of Type I and II hereditary angioedema are not life-threatening.

Angio oedema, Angioneurotic oedema. Reaction to external agent, Genetic disorder. Hereditary angioedema. References Book: Textbook of Dermatology. Fourth edition.Hereditary angioedema Mechanisms, diagnosis, and management Hereditary angioedema HAE is caused by a heterozygous deficiency of C1-inhibitor. HAE patients have intermittent cutaneous or mucosal swellings because of a failure to control local production of bradykinin.

Swellings typically evolve in several hours and persist for a few days. In addition to orofacial angioedema, painless swellings affect the extremities, leading to disfigurement or interference with work and other daily activities. Angioedema affecting the gastrointestinal tract or abdominal viscera is responsible for severe pain, often associated with vomiting due to edematous bowel obstruction.

Swellings may involve the larynx and be fatal, if untreated. In this paper, we review the clinical features, diagnosis, and management of HAE, with specific emphasis on the new therapeutic agents and treatment modalities such as self-treatment at home and prolonged prophylaxis. Les patients peuvent rapporter une sensation de tiraillement, de douleur, de tension voire de chaleur.

Ils ne sont pas inflammatoires. Sur le plan biologique, il y a donc un taux bas de C1-INH. La seule distinction est biologique. Dans ces contextes physiologiques, le taux de C4 est normal. Les formes acquises surviennent plus volontiers chez la personne de plus de 60 ans, sans contexte familial.

Angioedemas associated with urticaria are usually caused by histamine release and respond to anti-histamines and adrenalin.

They include allergic angioedemas, anaphylactoid reactions mostly drug-induced, e. NSAIDphysical angioedemas and recurrent idiopathic angioedema. Bradykinin probably plays a causative role in the pathogenesis of ACE-inhibitor or angiotensin II receptor blocker related angioedemas, as well as in the pathogenesis of the rare hereditary or acquired C1-inhibitor deficiency angioedemas. Urticaria is then typically absent and anti-histamines, as well as adrenalin, are ineffective. Rev Med Suisse ; volume 4.

Angio-œdème héréditaire

Hereditary angioedema is most frequently inherited, though it can also result from spontaneous defects during fetal development of certain genes, and has to do with dysfunction of a protein present in the body called C1 inhibitor. Both types of this condition may result in swelling of the face, lips, throat, and genitals, and the hereditary form can further cause extreme swelling in the abdomenhands and feet; it should also be stated that either form can be a medically serious condition that might require emergency medical attention.

With the exception of hereditary, common types of triggers that might cause angioneurotic edema include exposure to allergens, chemicals, medications, insect bites, or blood transfusions.

In fact angioedema can be a symptom associated with development of severe allergy or anaphylactic shock, and swelling of throat, lips and tongue must be taken very seriously. Typical treatments given for this condition could include antihistamines, but those who have frequent swelling may also need to carry injectable epinephrine.

These treatments only work for the non-hereditary form of angioneurotic edema. Moreover, anytime swelling is severe, people are advised to get medical help immediately, and not try to treat the condition on their own. Hereditary angioneurotic edema has some different symptoms. Before swelling in the face, mucus membranes and in other areas occurs, a person might have a flat rash for several days. The areas of the body that are swollen might differ with each person.

Great discomfort can occur when the abdomen swells, as this may result in pain, diarrhea, and vomiting or nausea. Swelling of the throat and larynx is very serious too, since it can impede breathing. There aren't always triggers for the hereditary form of this disease. Sometimes people note it occurs in association with certain times in the menstrual cycle, or right after dental work.
