	△CRP	56.10 ± 60.76	36.18 ± 46.19	<0.001
Neutrophil (%)	Before therapy	63.10 ± 16.06	60.57 ± 45.41	0.052
	After therapy	45.06 ± 15.51	37.99 ± 15.22	<0.001

Data are expressed as mean ± SD. IVIG = intravenous immunoglobulin; WBC = white blood cells; CRP = C-reactive protein; before therapy: value 1 d before IVIG treatment; after therapy: values 24 hours after IVIG treatment. △: the mean differences in laboratory data were calculated using the following equation: value 1 d before IVIG treatment minus values 24 hours after IVIG treatment.
