The scalp microbiota

The aim of this study is to compare the scalp microbiota of psoriasis vulgaris and seborrheic dermatitis both the lesion and lesion-free parts and also the control group and to assess their role on etiopathogenesis. Determining the microbiota of this region which is frequently involved and resistant to treatment may change the treatment approach. In addition, scalp microbiome of seborrheic dermatitis may be a causal factor of rapid relapse after treatment.

The similarities between the microbiota of the psoriasis vulgaris and seborrheic dermatitis cases with only scalp involvement can guide us not only for the diagnosis but also the treatment. There are a few reports about the role of Malassezia subgroups in the pathogenesis, but it is known that there are many different flora members on the scalp. Exposing these can change both our diagnosis and treatment options.

Does the microbiota of the patients change between the countries? To our knowledge, there is no similar studies in present. Presenting the scalp microbiome of Turkish population can be a start to understand whether there is a difference in terms of the countries.
