Increased plasma histamine levels in uraemic pruritus.
1. We determined plasma levels of histamine in uraemic patients and examined their correlation with the presence of pruritus. 2. In 27 patients with chronic renal failure, plasma histamine levels were analysed by radioimmunoassay and were compared with those of 40 healthy adult subjects. The control population showed plasma histamine concentrations of 185 +/- 33 pg/ml, which were significantly ...
متن کاملCowhage-Induced Itch as an Experimental Model for Pruritus. A Comparative Study with Histamine-Induced Itch
BACKGROUND Histamine is the prototypical pruritogen used in experimental itch induction. However, in most chronic pruritic diseases, itch is not predominantly mediated by histamine. Cowhage-induced itch, on the other hand, seems more characteristic of itch occurring in chronic pruritic diseases. OBJECTIVES We tested the validity of cowhage as an itch-inducing agent by contrasting it with the ...
متن کاملTopical aprepitant in clinical and experimental pruritus.
Comment. While privately insured patients enjoyed a 91% acceptance rate and relatively shorter wait times, the publicly insured patients faced significantly lower acceptance rates and longer appointment wait times. Despite making up less than 20% of the workforce, academic dermatologists provide most of the care for Medicaid patients in Ohio. Not only does this limit access to care for the publ...
متن کاملTopical surfactant-induced pruritus: involvement of histamine released from epidermal keratinocytes.
Surfactants, an important component of cleansers, often cause itch in humans. Topical application of sodium laurate and N-lauroylsarcosine sodium salt to the skin of mice immediately (for 1-1.5 hours) increased scratching, and the former increased scratching again between 2 and 3 hours after application. Thus, we examined the mechanisms of sodium laurate-induced delayed scratching. Sodium laura...
متن کاملSurfactant-induced chronic pruritus: Role of L-histidine decarboxylase expression and histamine production in epidermis.
Shampoo and cleansers containing anionic surfactants including sodium dodecyl sulphate (SDS) often cause pruritus in humans. Daily application of 1-10% SDS for 4 days induced hind-paw scratching (an itch-related behaviour) in a concentration-dependent manner, and 10% SDS also caused dermatitis, skin dryness, barrier disruption, and an increase in skin surface pH in mice. SDS-induced scratching ...
