Description
Psoriatic arthritis (PsA) is a heterogeneous chronic inflammatory disease which shares characteristic clinical features, genetic markers and family history with the larger group of seronegative spondyloarthopathies. The diverse clinical picture of PsA, including joint involvement, dactylitis, enthesitis, skin lesions of psoriasis and uveitis, indicates a need to identify suitable therapies to address different combinations of these manifestations.
