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.
METHODS: A total of 135 acute schistosomiasis inpatients were selected from 2001 to 2006. They all received the IHA antibody titer detection, and the correlation among the age, incubation period, and hospitalization days was calculated.
RESULTS: The antibody titers of IHA were higher than 1:320 in all the cases. The percentages of 1:640, 1:1 280, 1:2 560, 1:5 120 and 1:10 240 were 1.48%, 28.15%, 35.56%, 20.00%, and 14.81% respectively. The mean age was (47.70 ± 14.58) years, average incubation period was (38.03 ± 4.59) days and mean hospital stay time was (15.08 ± 3.79) days. The antibody titer value had no correlation with the age distribution (r = 0.109, P > 0.05). There was a negatively correlation between the antibody titer value and incubation 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 1:640 and above. There is no correlation between the antibody titer value and age, but the antibody titer value is higher, the incubation period is shorter and hospitalization time is longer.
