Clinical observation of treatment with interleukin2( IL-2) in recurrent respiratory tract infection

Objective To observe the clinical efficacy of interleukin2 (IL-2 ) in the treatment of children with recurrent respiratory tract infection( RRTI). Methods 160 children with RRTI from Mar 2005 to June 2008 in our hospital were divided into experimental group (n =80) and control group (n =80) randomly. IL-2 was given by hypodermic injection in experimental group and the other was treated with oral transfer factor. Then the clinical efficacy in two.groups was observed. Results The effects in the experimental group were superior to those in the control group(P <0.01). Conclusion IL-2 could enhance immunity and reduce the incidence rate of RRTI in children patients. The effects were superior to those patients treated with oral transfer factor.
