Objective:
To determine the impact of the disease in patients with PsA in daily clinical practice and to evaluate its relationship with its axial activity.
Methods:
A cross-sectional study was conducted in consecutive patients attended from January 2021 to December 2021 who met the CASPAR criteria, with clinical of inflammatory back pain and positive axial imaging, with or without peripheral involvement. Demographic, clinical, analytical data, HAQ index, PsAID12 and activity index (BASDAI and ASDAS-PCR) were also collected. Patients were divided into two groups, those with high impact and those with low impact according to PsAID results. Continuous variables are shown as median (Q1-Q3) and categorical variables as percentages and frequencies.
Results:
Of the 269 patients evaluated with PsA, 72 patients with axial involvement were included, 40 men (55.6%), with a median age of 54.1 years and disease duration of 7 years. 28.3% of the patients were obese and serum CRP level was 0.45 mg/dl (0.08-1.10). BASDAI was 4.2 (2.0-6.2) and ASDAS-PCR was 2.4 (1.5-3.2), which translates into 39.6% of patients in low activity or remission. The median PsAID total score was 3.9 (1.6-5.4), evaluated in 61 patients. The patients who achieved a PsAID12 ≤ 4 were 63%, mostly men and with lower CRP levels than PsAID ≥ 4 patients. In addition, low impact measured by the PsAID12 was associated with low results in BASDAI and ASDAS-PCR.
Conclusions:
Axial involvement reflected lower impact of the disease measured by PsAID12 and it is correlated with low activity measured by BASDAI and ASDAS-PCR.
