Pruritus and Atopic Dermatitis.
Summary of "Pruritus and Atopic Dermatitis."
Atopic eczema is one of the most pruritic skin diseases. Mediators of atopic eczema itch in the skin are still mostly unknown, but recent studies showed that the histamine 4 receptor plays an important role in itch pathophysiology; tryptase and interleukin-31 are also involved. Differences in itch perception and itch kinetics between healthy volunteers and eczema patients point towards an ongoing central nervous inhibitory activity in patients. Questionnaire studies reported comparatively higher loads in affective items chosen by patients with atopic eczema. In the concept of patient management, the therapy of clinical pruritus has to consider origin and perception of itch, namely the skin and the central nervous system, by combining topical and systemic treatment.

Medical and Biotech [MESH] Definitions
Dermatitis, Exfoliative
The widespread involvement of the skin by a scaly, erythematous dermatitis occurring either as a secondary or reactive process to an underlying cutaneous disorder (e.g., atopic dermatitis, psoriasis, etc.), or as a primary or idiopathic disease. It is often associated with the loss of hair and nails, hyperkeratosis of the palms and soles, and pruritus. (From Dorland, 27th ed)
Kaposi Varicelliform Eruption
A disseminated vesicular-pustular eruption caused by the herpes simplex virus (HERPESVIRUS HOMINIS), the VACCINIA VIRUS, or Varicella zoster (HERPESVIRUS 3, HUMAN). It is usually superimposed on a preexisting, inactive or active, atopic dermatitis (DERMATITIS, ATOPIC).
Dermatitis, Atopic
A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.
Antigens, Dermatophagoides
Antigens from the house dust mites (DERMATOPHAGOIDES), mainly D. farinae and D. pteronyssinus. They are proteins, found in mite feces or mite extracts, that can cause ASTHMA and other allergic diseases such as perennial rhinitis (RHINITIS, ALLERGIC, PERENNIAL) and atopic dermatitis (DERMATITIS, ATOPIC). More than 11 groups of Dermatophagoides ALLERGENS have been defined. Group I allergens, such as Der f I and Der p I from the above two species, are among the strongest mite immunogens in humans.
Netherton Syndrome
Rare autosomal recessive disease with variable expressions. Clinical features of the disease include variable ICHTHYOSIFORM ERYTHRODERMA, CONGENITAL; bamboo hair (trichorrhexis invaginata); and ATOPIC DERMATITIS. The disease is caused by mutations in the SPINK5 gene.
