CRP and primary ciliary dyskinesia: The clinical characteristics, levels of inflammatory indicators, pathogens, and imaging features of the lungs were compared between the two groups.<h4>Results</h4>The PCD group had higher levels of lymphocytes (42.80% versus 36.00%, <i>p</i> = 0.029) and eosinophils (2.40% versus 1.25%, <i>p</i> = 0.020), but lower neutrophil counts (3.99 versus 5.75 × 10<sup>9</sup>/L, <i>p</i> = 0.011), percentages of neutrophils (46.39% versus 54.24%, <i>p</i> = 0.014), CRP (0.40 versus 4.20 mg/L, <i>p</i> < 0.001) and fibrinogen (257.50 versus 338.00 mg/dL, <i>p</i> = 0.010) levels.
