The Relationship between Plasma Pentraxin 3 and Serum Amyloid P Levels and Disease Activity in Ankylosing Spondylitis

Table 3

Distribution of pentraxin 3 and serum amyloid P according to the ankylosing spondylitis disease activity score C-reactive protein.

ASDAS-CRP	Inactive (n = 22)	Low (n = 34)	High (n = 40)	Very high (n = 4)
PTX3, pg/mL, median (min-max)	3103.5 (10–7485.2)	2713.7 (10–12882)	2844.2 (10–20000)	2828.7 (1102.5–5989.3)	0.920
SAP, pg/mL, median (min-max)	61.7 (42.5–300)	84.2 (37.4–300)	57.8 (40.7–303.7)	50.9 (45.2–54.7)	0.673

ASDAS: ankylosing spondylitis disease activity score, CRP: C-reactive protein, PTX3: pentraxin 3, and SAP: serum amyloid P.
