Analysis of antibody titer value of IHA in 135 acute schistosomiasis patients / 中国血吸虫病防治杂志

ABSTRACT

Objective To analyze the antibody titer value of indirect haemagglutination test(IHA)in 135 confirmed acute schistosomiasis patients,so as to provide the evidence for improving the diagnosis and treatment of acute schistosomiasis. Meth-ods A total of 135 acute schistosomiasis inpatients were selected from 2001 to 2006. They all received the IHA antibody titer de-tection,and the correlation among the age,incubation period,and hospitalization days was calculated. Results The antibody titers of IHA were higher than 1320 in all the cases. The percentages of 1640,11280,12560,15120 and 110240 were 1.48%,28.15%,35.56%,20.00%,and 14.81%respectively. The mean age was(47.70 ± 14.58)years,average incuba-tion period was(38.03 ± 4.59)days and mean hospital stay time was(15.08 ± 3.79)days. The antibody titer value had no corre-lation with the age distribution(r=0.109,P>0.05). There was a negatively correlation between the antibody titer value and in-cubation period,(r=-0.558,P<0.01),there was a positive correlation between the antibody titer value and hospitalization time(r=0.791,P<0.01),and there were significant differences among different groups(F=17.07,64.53,both P<0.01). Conclusions The antibody titer of acute schistosomiasis cases detected by IHA is 1640 and above. There is no correlation be-tween the antibody titer value and age,but the antibody titer value is higher,the incubation period is shorter and hospitalization time is longer.
