Abstract:
Summary: Psoriatic arthritis is an inflammatory arthritis that is associated with psoriasis. Early
objectification joint pathology and conditioning treatment, slows progression of the disease and its
unfavorable prognosis. Clinicians pay great attention to psoriatic arthritis, which is motivated by certain
tendencies within global growth over the past three decades between 0.3 - 1% in population in general.
The aim of this research was to assessment the correlation between pain intensity, functional disability
and disease activity in psoriatic arthritis (PsA) patients with axial involvement. There were examined 47
patients suffering from psoriatic arthritis, with average age of 43.8 ± 1.6 years.
Material and Methods: The study included a cohort of patients selected according to the ASAS
criteria for PsA. The pain intensity was assessed by Visual Analog Scale (VAS) for pain. The disease
activity was estimated using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and
the functional disability was evaluated by Bath Ankylosing Spondylitis Functional Index (BASFI)
Results: We studied 47 patients, 44.1% females with mean age o f± SD 43.8 ± 1.6 years, and
disease duration of ± SD 11.0 ± 1.2 years. The pain intensity by VAS and functional disability by
BASFI was 6.7 ± 2.4 and respectively 5.4 ± 1.2 points. The disease activity was estimated at 5.7 ± 0.8 points, being appreciated as moderate-severe.
Was established a strong significance positive correlation between VAS and BASDAI
(p 0.0001), BASDAI and BASFI (p 0.0001). The VAS and BASFI had a moderate positive
interdependence, as shown in the table.
Conclusion: The Pain Intensity and Functional Disability Index have a high significance
positive correlation with the disease activity while between VAS and BASFI was revealed a
moderate positive correlation in psoriatic arthritis patients with axial involvement.
