Study of expression level of acute lower respiratory tract Boka virus infectecd children with serum specific antibody / 国际检验医学杂志

ABSTRACT

Objective To discuss the clinical value of the expression level of acute lower respiratory tract Boka virus (HBoV)in‐fectecd children whose detection serum specific antibody .Methods 904 cases of children with acute lower respiratory tract Boka vi‐rus infection hospitalized from March 2011 to July 2014 who were selected as study objects ,serum ,sputum ,bronchoalveolar lavage fluid HBoV DNA positive were as the gold standard for diagnosis of acute lower respiratory tract infection in HBoV ,the positive serum HBoV antibody of HBoV in children with acute lower respiratory tract infection was defined as the observation group ,serum HBoV antibody negative acute lower respiratory tract infection in children with HBoV was defined as the control group ,the correla‐tion between serum HBoV antibody and acute lower respiratory tract HBoV infection children whose clinical characteristics were analyzed .Results Serum HBoV antibody in the diagnosis of acute lower respiratory tract infection of HBoV whose sensitivity ,spe‐cificity ,positive predictive value ,and negative predictive value ,accuracy of diagnosis were separately 60 .32% 、90 .25% 、31 .67% 、96 .81% 、88 .16% .In the general data ,between the observation group and the control group in gender ,age ,hospitalization time , there were no significant differences(P>0 .05) .In the clinical manifestations ,nasal congestion and runny nose ,cough ,fever ,vomi‐ting and diarrhea ,shortness of breath ,breathing difficulties whose occur rates had no significant differences between the observation group and the control group(P>0 .05) ,the incidence of wheezing of the observation group was significantly higher than that of the control group ,the difference had statistical significance (P0 .05) .Conclusion Serum HBoV antibody is in favor of acute lower respiratory tract infection of HBoV in the diagnosis of exclusion ,and the serum HBoV antibody positive and acute lower respiratory tract infection of HBoV have a certain relationship in children with wheezing symptoms .
