[Prognostic factors in psoriatic arthritis]. / Factores pronóstico en la artritis psoriásica.

ABSTRACT

Peripheral psoriatic arthritis is an inflammatory and progressive disease; its burden, either at the structural level or the function and quality of life, is similar to other chronic poliarthritidies. In spite of treatment with synthetic or biologic DMARDs, remission is only achieved in about 30% of the patients. From a clinical point of view, persistent joint activity (tender and swollen joints) is a factor leading to joint damage progression. These data indicate the need for a tight follow up and treatment of the patients.
