Comparison of Malassezia Spp Proportions in Inflammatory and Non Inflammatory Facial Acne Vulgaris...
Acne VulgarisAcne vulgaris (AV) is a common inflammatory condition involving pilosebaceous unit. The pathogenesis of acne is multifactorial and skin microbiome is considered to be one of the key factors that aggravate inflammation. Malassezia spp is normal flora on the skin and several studies have reported its corelation with inflammatory AV lesion. Malassezia have higher lipase activity compared to Propionibacterium acnes which triggers an increase in free fatty acid and glycerol, the chemotactic factors towards neutrophils and inducing inflammation in AV. Malassezia folliculitis (MF) is sometimes confused with and may present together with AV. Pruritus usually presents in MF but some studies also reported itching as common symptom in AV. The objectives of this study were to identify the presence and the distribution of Malassezia spp. in facial AV lesions, to compare the distribution of Malassezia spp. between inflammatory and non-inflammatory lesions and to identify the association between Malassezia spp in acne lesions and pruritus symptom.
