Introduction[edit | edit source]
It is a life threatening syndrome that results from sudden release of basophil derived mediators and mast cells into blood circulation.
However, no universally accepted clinical definition has been found. According to some clinicians it is defined as a syndrome of one or more than one systemic signs and symptoms but does not identify the specific features alone or in combination.
French physiologist Charles Robert Richet in 1913 was awarded with Nobel prize in Medicine and Physiology for his collaborative research with Paul Portier on anaphylaxis. [1]
Classification[edit | edit source]
It has been classified into 3 categories on basis of severity of symptoms.
- Severe Reactions: It includes clinical features such as confusion, incontinence, collapse and unconsciousness and are associated with hypotension and hypoxia.
- Moderate Reactions: Diaphoresis, presyncope, dyspnea, vomiting, stridor, wheeze, chest tightness, nausea and abdominal pain has weak but significant association and is used to define moderate reactions.
- Mild Reactions: It includes reactions which are limited to skin such as urticaria, erythema, and angioedema. [2]
