Canine atopic dermatitis: systemic immunomodulatory protocol based on clinical phenotype
ABSTRACT: Canine atopic dermatitis (cAD) is a multifactorial allergic disease associated with immune dysfunction and abnormal skin barrier. Several immunological mediators play a role in its pathogenesis. Such molecules are produced by the activation of T helper lymphocytes (Th) through polarization to Th1 and/or Th2, which contributes to different lesion patterns. Acute lesions are mediated by an activation of the Th2 cytokine axis, which clinically induces erythema and pruritus. Conversely, in chronic injuries a mixed immune response of Th1/Th2 cytokines occurs, leading to hyperpigmented and lichenified skin. The clinical understanding of these patterns and the mode of action of immunomodulators are crucial for the best clinical management of the atopic patient. In this context, this review discussed the role of the immune response and the immunomodulatory drugs in dogs with atopic dermatitis and suggested a therapeutic protocol based on clinical phenotype. Based on the evidences showed in this review, it is considered appropriate to use immunomodulatory drugs that target cytokine spectrum related with the clinical phenotype of cAD.
期刊介绍:
The purpose of Ciência Rural is to publish the results of original research, note and reviews which contribute significantly to knowledge in Agricultural Sciences. Preference will be given to original articles that develop news concepts or experimental approaches and are not merely repositories of scientific data. The decison of acceptance for publication lies with the Editors and is based on the recommendations of Editorial Comission, Area Committee and/ or ad hoc reviewers. The editors and reviewers are external to the institution.
