OBJECTIVETo explore the effect of composite salvia injection (CSI) on platelet parameters in children with anaphylactoid purpura (AP) and its clinical significance.

METHODSOne hundred and fifty children with AP were assigned to two groups, 80 in Group A and 70 in Group B. They were treated, respectively, with conventional therapy only or conventional therapy combined with CSI. Their platelet parameters, including blood platelet count (BPC), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) were determined at the acute stage and convalescent stage, respectively.

RESULTSAt the acute stage, the BPC in AP children of both groups was in the normal range, but significant abnormality was shown in the levels of MPV, PDW and PCT. As for comparisons of these parameters at the convalescent stage, significant difference between the two groups was also shown in terms of MPV, PDW and PCT (P<0.05 or P<0.01).

CONCLUSIONAlthough platelet shows no quantitative change in the pathogenic process of AP, important functional changes are surely existent. CSI could promote the normalization of platelet function.
