Comparison of the efficacy of rituximab injection and splenectomy for the treatment of chronic primary immune thrombocytopenia / 中国基层医药

ABSTRACT

Objective To compare the efficacy and adverse reaction of rituximab injection( Rituximab) and splenectomy in the treatment of adult chronic idiopathic thrombocytopenic purpura ( ITP). Methods From March 2013 to June 2015,105 chronic ITP patients who were treated in the Fifth People＇s Hospital of Datong were divided into rituximab group(n=43) and splenectomy group( n =62).The clinical efficacy,adverse reaction and survival time of the two groups were compared.Results There was no statistically significant difference in baseline character-istics between the two groups. After treatment for 3 months, the response rates of the splenectomy group and the rituximab group were 91. 9%( 57/62 ), 69. 8%( 30/43 ), respectively, the difference was statistically significant between the two groups(χ2 =5.04,P=0.005).After treatment for 12 months,the response rates of the splenectomy group and the rituximab group were 88.7%(55/62),58.1%(25/43),respectively,the difference was statistically significant between the two groups ( χ2 =6. 83, P =0. 001 ), respectively. After treatment for 3,12 months, the complete response rates of the splenectomy group were 82.2%(51/62),80.6%(50/62),respectively,which were higher than those of the rituximab group [39.5%(17/43),34.9%(15/43)] (χ2 =7.25,P＜0.001).There was no statistically significant difference in adverse reactions after treatment for 1 year between the two groups(P>0.05). The survival time of the splenectomy group was longer,but there was no statistically significant difference( t=4.85, P=0.18).Conclusion The curative effect of splenectomy in the treatment of adult ITP is better than rituximab,and the adverse reaction is not obvious between two methods.
