[Therapy of Psoriasis Arthritis Taking into Account New Treatment Options].

Therapy of Psoriasis Arthritis Taking into Account New Treatment Options Abstract. Psoriatic arthritis occurs in about 20-30 % of patients with psoriasis. The disease is heterogeneous and can involve a variety of the distinct anatomical sites. The choice of medication depends on the type and the severity of clinical features. The recommendations of EULAR and GRAPPA serve as a guide for the choice of medication, which is used in sequential treatment steps. This is presented in our review in usable, simplified terms. Potential comorbidities leading to contraindication for certain treatments are considered. We present new and highly effective treatments, based on the pathogenesis of psoriasis and psoriatic arthritis, targeting the IL-23/IL-17 pathway.
