CRP and Sjogren syndrome: The serum concentrations of PFNA (2.0 (1.4, 3.3) ng/mL vs. 1.7 (1.2, 4.0) ng/mL; p = 0.4173), PFDA (1.7 (1.1, 2.9) ng/mL vs. 1.6 (0.5, 3.1) ng/mL; p = 0.2804), PFUdA (1.3 (0.8, 2.0) ng/mL vs. 1.2 (0.3, 2.8) ng/mL; p = 0.5290) and PFHxS (1.9 (1.0, 3.8) ng/mL vs. 2.2 (0.8, 5.0) ng/mL; p = 0.6361) were found to be higher in Sjogren’s syndrome patients with normal serum CRP (CRP ≤ 8 mg/L) than in those with high serum levels of CRP (CRP > 8 mg/L), but the difference did not reach statistical significance.
