Psoriatic rheumatism has seen many recent therapeutic advances, as well as new recommendations highlighting the importance of specifying certain prognostic factors in order to manage this condition early. To this end, 63 patients were studied for psoriatic rheumatism, comparing those with clinical and/or radiographic progression of the disease with those whose rheumatism is in a state of so-called minimal activity. A significant correlation was found with the extent of cutaneous psoriasis, polyarticular involvement and biological inflammatory syndrome. Our results were then compared with those in the literature.
