This study aimed to evaluate the relationships between C-reactive protein (CRP)/albumin ratio (CAR), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and Disease Activity in Psoriatic Arthritis (DAPSA) and Psoriatic Arthritis Impact of Disease 12-item-questionnaire (PsAID 12) scores in patients with psoriatic arthritis (PsA). The results showed that CAR can be useful as a simple and quick assessment method to evaluate disease impact in PsA.
Aim To evaluate the relationships between the C-reactive protein (CRP)/albumin ratio (CAR), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and Disease Activity in Psoriatic Arthritis (DAPSA) and Psoriatic Arthritis Impact of Disease 12-item-questionnaire (PsAID 12) scores in patients with psoriatic arthritis (PsA). Methods This cross-sectional study involved 160 (121 female) patients with PsA who were >18 years old and treated in the rheumatology clinic of Di5kapi Yddmm Beyazit Education and Research Hospital between January 2020 and January 2021. Demographic and clinical data, PsAID 12 and DAPSA scores, CRP, erythrocyte sedimentation rate (ESR), albumin level, neutrophil, lymphocyte, and platelet counts were recorded. Results The mean age was 46.49 +/- 711.12 years; median (min-max) disease duration was 2 years (0.5-34). The PsAID score was >= 4 (high disease impact) in 74.4% of patients. Patients with high disease impact had significantly higher CRP, ESR, CAR, NLR, PLR, neutrophil counts, and DAPSA scores (P<0.001). PsAID scores significantly highly correlated with CRP (rho 0.864, P<0.001), DAPSA significantly highly correlated with the CAR (rho 0.890, P<0.001). Receiver operating characteristic curve analysis showed that the CAR (area under the curve [AUC] 0.901, P<0.05, 95% confidence interval [Cl] 0.855-0.94/, NLR (AUC 0.759, P < 0.05, 95% CI 0.680-0.838), and PLR (AUC 0.686, P < 0.05, 95% CI 0.591-0.782) predicted high disease impact. The cut-off value for the CAR was 0.98. Conclusion The CAR can be useful in daily practice as a simple and quick assessment method to evaluate disease impact in PsA.
