CRP and Behcet disease: The mean values of ANC (P = 0.010 < 0.05), CRP (P < 0.001) and SAA (P < 0.001) in disease episodes were found to be significantly lower in BD compared with PFAPA patients, while the difference in fibrinogen (P = 0.056 > 0.05) and procalcitonin (P = 0.756 > 0.05) values was not statistically significant (Table 2).
