Abstract:
Objective To investigate the chanegs and correla iton between IL-17 and MMP-9 in c hildren of henoch-schonlein purpura,and to explore the pathogenesis of teh IL-17 and MMP-9 in henoch-schonlein pur-pura /henoch-schonlein purpura nephritis.Methods The level of serum IL-17 andMMP-9 in 74 henoch-schon-lein purpura childr en in initial stage and 30 cases of healthy children( control group) were detetced by ELISA. Results (1) The level of plasma IL-17 was significantly higher in children of henoch-schonlein purpura thna tha t foh ealthy control group (86.59 ±35.50) fg/L vs.(62.38 ±14.65)fg/L,P<0.01].(2) The level of plasma MMP-9 was significantly higher in children of henoch-schonlein pupru ar than that o fhealt hy control group [(201.82 ±105.87) fg/L vs(89.27 ±27.99)fg/L,P <0.01].(3) Henoch-schonlein purpura children were followed up for6 months,dependin g on whether the kidney was involved,they were devided into non-he-noch-schonlein purpura nephritsi grou p nad henoch-s chonlein purpura nephritis group.In initial phase of HSP,the level of plasma IL-17 was significant lyhigher in henoch-schonlein purpura nephritis group than non-henoch-schonlein purpura nephrits group [(101.67 ±39.55) fg/L vs.(101.67 ±39.55)fg/L,P<0.05].The level of p lasma MMP-9 was significantly higher in henoch-schonlein purpura nephritsi group than no n-henoc h-schon-lein purpura nephritis group [(249.63 ±97.57) Pg/L vs.(185.30 ±104.39) pg/L,P<0.05 ].(4) IL-17 and MMP-9 correlation aanlysis didn't show sign ificant correlation(r=0.184,P>0.05).Conclusion IL -17 and MMP-9 are involved in the pathogenesis of henohc-schonlein purpura/henoch-schonlein pur pura nephritis.
