PsA are included in the group of HLA-B27-associated joint diseases, united in the group of seronegative spondylitis (SSA). At the same time, this disease differs from ankylosing spondylitis and other spondylitis with a particularly diverse clinical picture and the existence of only the syndromes inherent in it, for example, intermittent synovitis, palindromic rheumatism or mutilating arthritis.
Purpose of the study
Research of clinical heterogeneity of early psoriatic arthritis and the possibility of early diagnosis.
The current study included 104 patients with PsA who were admitted to the rheumatology and arthrology departments of the IMSP Republican Clinical Hospital „Timofei Moşneaga” from 2003 to October 2021.
The frequency of expression of individual clinico-anatomical variants of joint syndrome was different in patients with PsA-e and PsA-t (in PsA-e compared to PsA-t, the oligoarticular variant was significantly more likely to be observed (43.1% and 19%, respectively, p=0.01) and less often the variant of spondyloarthritis (7.8% and 19%, p=0.1), while the variant of polyarthritis (33.3% and 38%, p = 0,6) and distal interphalangeal (15,7% and 15%, p=0,9) were detected with the same frequency, as regards the mutilating variant, this was observed only in PsA-t.
The early stage of psoriatic arthritis is characterized by pronounced heterogeneity of manifestations of joint syndrome and damage to the tendon-ligament apparatus. In PsA-e oligoarthritis and polyarticular variants are the most common, less often - distal interphalangeal and spondyloarthritic. In the first 3 months after the onset of clinical manifestations of PsA, oligoarthritis was observed in 75.4% of patients and polyarthritis in 14% (p=0.0001), and after 6 months - 63% and 26.6% respectively (p=0.001). With a progression of the duration of the disease, the number of patients with arthritis increased, and by the end of the 2nd year was determined in 47.6% of patients, and oligoarthritis - in 28.6%.
