Sequential Increase in Complement Factor I, iC3b, and Cells Expressing CD11b or CD14 in Cutaneous Vasculitis

Table 1

The number of CD11b⁺, CD14⁺, or complement factor I (CFI)⁺ cells and the staining score of iC3b in skin biopsies from patients with immunocomplex-mediated cutaneous small vessel vasculitis.

	CD11b (cells/mm^2)	CD14 (cells/mm^2)	CFI (cells/mm^2)	iC3b (score)
Nonlesional skin ()
Initial petechiae ()		^#	^&
Palpable purpura ()		^##	()

The results are expressed as the . “” denotes and “” when the CD11b⁺ cell numbers in the initial petechial lesion and palpable purpura, respectively, were compared to the corresponding cell numbers in the nonlesional skin (paired -test); “#” denotes and “##” when the CD14⁺ cell numbers in the initial petechial lesion and palpable purpura, respectively, were compared to the corresponding cell numbers in the nonlesional skin (paired -test); “&” denotes when the CFI⁺ cell numbers in the initial petechial lesion were compared to the corresponding cell numbers in the nonlesional skin (paired -test); and “” denotes when the iC3b scores in the palpable purpura were compared to the corresponding scores in the nonlesional skin (mixed model analysis).
