Psoriasis and Malassezia Yeasts
نویسنده
چکیده
Currently, the genus Malassezia includes 14 species, which have been identified traditionally based on their morphology and biochemical features (Cafarchia et al., 2011). Since the description of new species a number of studies have evolved to elucidate the role of the different species in the ecology and pathogenicity in a range of dermatoses, in which variable results have been reported from different geographical regions.

Psoriasis and infestation with Malassezia
Psoriasis is a chronic proliferative disease with a reported 0.3-4.8% prevalence in different resources. Its etiology is still undetermined, but interfering genetic and environmental factors in its pathogenesis are known to be substantial [1]. One of the considered environmental factors is infestation with malassezia yeast. Malassezia’s role in psoriasis is still not determined, yet several stu...
متن کاملScalp psoriasis: synergy between the Malassezia yeasts and skin irritation due to calcipotriol.
To investigate if there is a synergy between the presence of the Malassezia yeasts and the adverse reaction during treatment of scalp psoriasis with calcipotriol scalp solution, patients were treated with itraconazole to reduce the number of Malassezia yeasts. This study was a double-blind, placebo-controlled parallel group study between oral itraconazole or placebo for 8 weeks in patients with...
متن کاملSkin diseases associated with Malassezia species.
The yeasts of the genus Malassezia have been associated with a number of diseases affecting the human skin, such as pityriasis versicolor, Malassezia (Pityrosporum) folliculitis, seborrheic dermatitis and dandruff, atopic dermatitis, psoriasis, and--less commonly--with other dermatologic disorders such as confluent and reticulated papillomatosis, onychomycosis, and transient acantholytic dermat...
متن کاملSkin diseases associated with Malassezia yeasts: facts and controversies.
The implication of the yeast genus Malassezia in skin diseases has been characterized by controversy, since the first description of the fungal nature of pityriasis versicolor in 1846 by Eichstedt. This is underscored by the existence of Malassezia yeasts as commensal but also by their implication in diseases with distinct absence of inflammation despite the heavy fungal load (pityriasis versic...
متن کاملPsoriasis and infestation with Malassezia
Abstract Background: Psoriasis is a chronic proliferative condition of the skin. Its accurate pathogenesis has not been known yet, but interactions between genes and environmental factors have been implicated in its initiation. The role of malassezia in psoriasis is still undetermined, but several reports have associated these lipophilic yeasts with the development of skin lesions in psoriasis...
