Telomerase Expression in Peripheral Blood Mononuclear Cells in Children with Acute Kawasaki Disease / 实用儿科临床杂志

ABSTRACT

Objective To study the telomerase expression in peripheral blood mononuclear cells(PBMCs) in children with acute Kawasaki disease(KD) and its clinical significance.Methods The PBMCs of 64 children with acute KD [25 cases of them with coronary artery lesions(CAL),while the rest without] from 2 months to 6 years old admitted into Jiangxi Children's Hospital from Mar.2005 to Dec.2008 and those of 52 sex-age-matched healthy children (healthy control group) from 5 months to 7 years old were all assayed by Roche telomerase polymerase chain reaction enzymelinked immunosorbent assay(PCR ELISA).WBC,ESR and CRP were also detected.SPSS 11.0 software was used to analyze the data.Results The telomerase expression frequency of PBMCs in children with KD was 32.8%(21/64 cases),while that in healthy control group was only 15.4%(8/52 cases),the difference between the 2 groups was significant (?2= 4.65,P0.05).There were no significant difference of WBC,ESR and CRP between the telomerase of PBMCs positive group and negative group.Conclusions The higher frequency of telomerase expression in peripheral blood lymphocytes might be related to the development and progression of KD.
