RESUMEN
Objective To investigate the changes of serum procalcitonin (PCT), interleukin-6 (IL-6) and C reactive protein (CRP) in children with Henoch-Sch?nlein purpura (HSP) combined with surgical complications. Methods From January 2010 to June 2013, 48 children with HSP combined surgical complications were enrolled, the fasting venous blood were obtained in day 1, 3, 5 of admission and before discharge. Meanwhile, 30 healthy children were selected as control. Results Compared with the control group, the levels of serum PCT and IL-6 in day 1, 3, 5 of admission, and the levels of serum CRP in day 1, 3 of admission were higher in children with HSP combined with surgical complications (all P<0.01). The differences of levels of serum PCT, CRP and IL-6 in day 1, 3, 5 of admission and before discharge were statistically signiifcant between surgical group and non-surgical group. All these indicators showed a gradual downward trend. Compared with surgical group, the levels of serum PCT and IL-6 in day 3, 5 of admission and serum CRP in day 5 of admission were signiifcantly lower in non-surgical group (P<0.05). There were positive linear correlations between the level of serum PCT and IL-6, and between the level of PCT and CRP (r=0.48, 0.62, P<0.01). Conclusions The changes of serum PCT, IL-6 and CRP may be associated with the occurrence of surgical complications in children with HSP, monitor these indicators may help to assess the condition and to guide the treatment.
