Diseases of the immune system (immunology)

Eosinophilic fasciitis

Eosinophilic fasciitis is a rare disease characterized by symmetrical and painful inflammation, swelling, and induration of the skin of the lower and upper extremities. Diagnosis is made by skin and fascia biopsy.

Mastocytosis: causes, symptoms, diagnosis, treatment

Mastocytosis is the infiltration of mast cells into the skin and other tissues and organs.

Hypersensitivity to medicines: causes, symptoms, diagnosis, treatment

Drug hypersensitivity is an immune-mediated reaction.

Autoimmune conditions: causes, symptoms, diagnosis, treatment

In autoimmune conditions, antibodies are produced to endogenous antigens.

Anaphylaxis

Anaphylaxis is an acute, life-threatening, IgE-mediated allergic reaction that occurs in previously sensitized patients upon re-exposure to a familiar antigen.

Allergic rhinitis

Allergic rhinitis causes itching, sneezing, rhinorrhea, nasal congestion, and sometimes conjunctivitis due to contact with pollen or other allergens seasonally or year-round.

Atopic and allergic conditions: causes, symptoms, diagnosis, treatment

Type I hypersensitivity reactions include atonic and many allergic disorders.

Latex allergy: causes, symptoms, diagnosis, treatment

Latex sensitivity is an exaggerated immune response to water-soluble proteins contained in latex items (such as rubber gloves, dental dam rubber, condoms, intubation tubes, catheters, enema tips with an inflatable latex cuff), which leads to urticaria, angioedema, and anaphylaxis.

Congenital angioedema: causes, symptoms, diagnosis, treatment

Hereditary angioedema is a consequence of deficiency (type 1, in 85% of cases) or dysfunction (type 2, in 15% of cases) of the C1 protein inhibitor, which regulates complement activation via the classical pathway.

Angioedema

Angioedema is swelling of the deep layers of the dermis and subcutaneous tissues. It can be caused by drugs, poison (especially animal), food or extracted allergens.
