Abstract:
Abstract- Sensitisation to the house dust mite, Dermatophagoides farinae, was demonstrated by skin testing and allergen-specific IgG determination in 15 out of 20 dogs in which a definitive diagnosis of sarcoptic mange was made following recovery of Sarcoptes scabiei mites on skin scrapings. After therapy, no dogs exhibited clinical signs of atopic dermatitis. Intradermal skin testing and 40 per cent of specific IgG assays for Dermatophagoides farinae were negative 90-180 DAys after the original diagnosis. Résumé- Une sensibilisation a l'acarien de la poussière de maison, Dermatophagoides farinae, est demontrée par tests cutanés et dosage d'immunoglobulines IgG specifiques d'allergenes sur 15/20 chiens atteints de gale sarcoptique prouvée par la presence de nombreux sarcoptes aux raclages cutanés. Après traitement, aucun chien n'a présenté des signes cliniques de dermatite atopique. Les tests cutanés intradermiques et 40 plus des posages IgG pour Dermatophagoides farinae sont negatifs 90 à 180 jours après le diagnostic initial. [Prélaud, P., Guaguère, E.

Allergic Reactions
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
