The significance of allergen-specific IgE as marker for severity of atopic dermatitis is controversial. The aim of this study was to determine the frequency of IgE-mediated sensitisation to food and environmental allergens in 132 children and 67 adults with atopic dermatitis, and its correlation to severity of atopic dermatitis (SCORAD). Total IgE was elevated (> 100 kU/l) in 79.7% of adults an...
Despite being considered an emerging yeast related to immunocompromised individuals, severe infections by Malassezia furfur have not been evaluated. During a one-year survey on yeasts fungemia, 290 neonatal and 17 pediatric patients with intravascular catheters, lipid parenteral nutrition, prolonged ward stay, and surgery were enrolled. In addition, the origin of the infection was investigated ...
Malassezia spp. are a component of the cutaneous microflora that colonizes lipid-rich areas, especially the head and neck, because the microorganisms require a lipid for its growth. An antiMalassezia-specific immunoglobulin E antibody is produced in patients with atopic dermatitis who have disrupted skin barrier function, while healthy subjects do not produce the immunoglobulin E antibody. In a...
During anti-Malassezia screening of plants by CLSI broth microdilution method, Cladia aggregata (Swartz) Nyl. (family Cladoniaceae), a fruticose lichen from Sikkim (northeast Himalayan region), has been found effective at minimum inhibitory concentrations (mg/mL) of 2.72, 0.63, and 1.28 against yeast-like fungi namely, M. furfur, M. globosa and M. sympodialis, respectively. These test pathogens...
Malassezia is a unique lipophilic genus in class Malasseziomycetes in Ustilaginomycotina, (Basidiomycota, fungi) that otherwise consists almost exclusively of plant pathogens. Malassezia are typically isolated from warm-blooded animals, are dominant members of the human skin mycobiome and are associated with common skin disorders. To characterize the genetic basis of the unique phenotypes of Ma...
TO THE EDITOR Seborrheic dermatitis (SD) is a chronic inflammatory disease that compromises skin areas rich in sebaceous glands, such as the face, scalp, and upper trunk. The condition is frequently observed in acquired immune deficiency syndrome patients (30–85% compared with 3–5% of immunocompetent adults). Its appearance is considered to be an early marker of the evolutionary trend of HIV in...
Background and purpose: Seborrhoeic dermatitis (SD) is a common skin disorder. Malassezia yeasts have an important role in the etiology of SD. Since anti-fungal agents, especially in azoles are effective for treating SD, in this study, the effect of ketoconazole 2% solution on clinical signs and Malassezia in SD patients were assayed. Materials and methods: 100 patients with SD were enro...
The in vitro activity of a new triazole R126638 against Malassezia yeasts was compared with that of ketoconazole. With the agar dilution technique, minimal inhibitory concentrations were lower for R126638 compared with ketoconazole against Malassezia globosa, M. obtusa, M. slooffiae, M. restricta and two strains of M. sympodialis. On human stratum corneum in vitro, both R126638 and ketoconazole...
materials and methods in total, among 134 patients clinically suspected of having pityriasis versicolor, attending the department of mycology, boali sina hospital and referral laboratory of the mazandaran university of medical sciences, 116/134 (86.5%) positive patients for malassezia elements, namely, yeast cells and short hyphae in microscopic examination, were included in the study. all 116 ...
