Introduction. Psoriasis is a chronic autoimmune disease of skin which
may affect around 2% of population and 20-40% of psoriatic patients
develops psoriatic arthritis (PsA). It is estimated that cutaneous symptoms
outpace musculoskeletal symptoms for about 10 years. Prompt
diagnosis and implementation of treatment are crucial for the achieving
of remission and better prognosis.
Aim. The aim of the study was to assess the occurrence of PsA among
patients with psoriasis as well as clinical manifestation.
Material and methods. 180 subjects with psoriasis of the skin and/or
nails were enrolled in the study. The screening questionnaire was created
to assess the frequency of musculoskeletal symptoms and their
character. The symptoms reported by the patients were compared
with the CASPAR classification and with screening questionnaire PEST.
Results. More than 90% of responders declared complaints from
musculoskeletal system ever. In 70% of surveyed symptoms were present
during filling up the questionnaire and in 40% reported symptoms
fulfilled the criteria of inflammatory arthritis. About 23% of responders
have never been diagnosed and almost 40% of the responders declared
to be diagnosed to have psoriatic arthritis. Interestingly 27.68%
of patients never diagnosed, fulfilled CASPAR criteria for psoriatic arthritis.
Conclusions. Musculoskeletal complaints are frequent among patients
with psoriasis. The significant percentage of patients treated
by dermatologist doesn’t have any diagnosis of inflammatory joint
disease despite the presented symptoms. These patients should be
referred to rheumatologist for further evaluation.
