血吸虫病患者治疗前后特异性IgG4抗体的观察

[目的 ]观察血吸虫病患者治疗前后特异性IgG4抗体的变化。[方法 ]ELISA法。 [结果 ]2 7例血吸虫病患者治疗前SEA IgG4和AWA IgG4阳性率分别为 96 3%和 10 0 % ,平均OD值分别为 1 6 2和 0 72。治疗后 6月复查 18例 ,阳性率分别为 94 4%和 10 0 % ,平均OD值分别为 1 0 6和 0 5 6。治疗后 12月复查 2 7例 ,阳性率分别为 96 3%和 92 6 % ,平均OD值分别为 0 99和 0 5 8。 [结论 ]2 7例血吸虫病患者SEA IgG4和AWA IgG4治疗前后阳性率无明显变化 ,但抗体水平有所下降。

OBSERVATION ON SPECIFIC IgG4 ANTIBODY OF SCHISTOSOMIASIS PATIENTS BEFORE AND AFTER TREATMENT

OBJECTIVE: To observe the alteration of specific IgG4 antibody of schistosomiasis patients before and after treatment. METHODS: ELISA. RESULTS: The SEA-IgG4 and AWA-IgG4 positive rates of 27 schistosomiasis cases were 96.3% and 100%, respectively, their average OD values were 1.62 and 0.72. 6 months post treatment 18 cases were followed up, the positive rates were 94.4% and 100%, respectively, their average OD values were 1.06 and 0.56, respectively. 12 months post treatment all cases were followed up, the positive rates of SEA-IgG4 and AWA-IgG4 were 96.3% and 92.6%, respectively, their average OD values were 0.99 and 0.58, respectively. CONCLUSION: No obvious changes were found in the SEA-IgG4 and AWA-IgG4 positive rates of 27 schistosomiasis cases before and after treatment, whereas the antibody level of specific IgG4 was decreased.
