Abstract

Background and Design: Atopic dermatitis (AD) is a multifactorial disease in which Malassezia species are also considered to be one of the factors that exacerbate AD. We have developed a culture-independent method for analyzing cutaneus Malassezia load in patients with atopic dermatitis. Materials and Methods: The diversity of Malassezia flora in Turkish patients with atopic dermatitis of three different clinical severities (mild, moderate, and severe) were compared using quantitative real time polymerase chain reaction (qRT-PCR) method. Fourthy-seven individuals with AD and seventy-five adult healthy individuals were sampled in this study. Skin samples were collected by stripping the face and neck of each subject. Fungal DNA extraction was performed and the detection of Malassezia DNA by real-time PCR was conducted. Results: Total number of patients was 122, including 47 patients and 72 healthy controls (62 female, 60 male). Quantitative analysis of Malassezia colonization in the AD group and healthy control group was not significantly different between the AD and healthy control groups. In patients with severe AD, Malassezia colonization was not different that in mild and moderate AD patients and healthy individuals, and the differences among them were not statisticaly significant (p=0.409). Conclusion: We could not find any difference in our patient group in terms of Malassezia colonization rate, although we had hypothesized. We could not show a fungal factor for the severity of the disease in AD patients. Japanese authors showed such a kind of relationship in the past. Besides, skin diseases should be evaluated carefully for the presence of microorganisms as an important factor of pathogenesis of the disease. (Turk derm 2011; 45: 206-9)

Özet

Amaç: Atopik dermatit (AD) etyolojisinde ve hastalık alevlenmesinde Malassezia cinsi mayaların rolü olduğu bildirilmektedir. Bu çalışmada atopik dermatitli hastalarda derideki Malassezia yükünü göstermek için geliştirilen, kültürden bağımsız bir moleküler yöntem sunulmaktadır. Gereç ve Yöntem: Üç farklı (hafif, orta, ciddi) klinik evredeki atopik dermatitli hastaların Malassezia kolonizasyon oranları, kantitatif gerçek zamanlı polimeraz zincir reaksiyonu (kGZ-PZR) kullanılarak incelenmiştir. Kırk-yedi (47) atopik dermatitli hasta, ve 75 erişkin sağlıklı birey çalışmaya dahil edilmiştir. Hastaların ve sağlıklı grubun yüz ve boyunda lezyon olan ve olmayan bölgelerinden deri kepek örnekleri flastere yapıştırılarak alınmıştır. Flastere yapışan kepek örneklerinden fungal DNA izole edilmiş ve Malassezia DNA’sının gösterilmesi için GZ-PZR işlemine alınmıştır. Bulgular: Olgu sayısı 47 hasta, 75 sağlıklı birey olmak üzere (62 kadın, 60 erkek) 122’dir. Kantitatif analizlere göre Malassezia kolonizasyonu AD ve sağlıklı grup arasında farklı bulunmamıştır. Ciddi AD’i olan grup ile orta veya hafif AD’i olan gruplar arasında Malassezia yükü açısından bir fark gösterilememiştir (p=0,409). Sonuç: Çalışmamızın başında, daha önceki Japon çalışmalarında gösterilen Malassezia yükü ile AD arasındaki ilişkiyi bulmayı amaçlamamıza rağmen, çalışma sonunda Türk AD grubunda sağlıklı gruptan farklı bir fungal yük bulunmamıştır. Ancak, deri hastalıklarının patogenezinde mikroorganizmaların rolü konusunda çalışmalara devam edilmelidir. (Türk derm 2011; 45: 206-9)
