上转换发光技术侧流免疫夹心法检测麻风患者和家庭接触者PGL-I抗体水平

         

摘要

Objective:To evaluate the value of lateral flow immuno-sandwich assay using up-converting phosphor reporter particles ( UCP-LFA) in predicting the risk of leprosy contacts by detecting PGL-I antibod-y. Methods:The PGL-I IgM levels were measured by UCP-LFA in 59 leprosy patients, 87 household con-tacts and 55 healthy controls in Guizhou. Results:The positivity rates of anti-PGL-I IgM in leprosy patients, household contacts and healthy controls were 81. 4%, 5. 7% and 1. 8%, with significant differences between them ( P<0. 005 ) . The positivity rates of anti-PGL-I IgM in patients with paucibacillary ( PB ) and multibacillary leprosy ( MB) were 45.5% and 89.4%, with a significant difference ( P<0.005) . The positivity rates of anti-PGL-I IgM in the patients with BI+and BI-were 83% and 0%, with a significant difference ( P<0.005) . Conclusion:PGL-I IgM antibody can predict the risk of leprosy.%目的:评估上转换发光技术侧流免疫夹心法(UCP-LFA)检测PGL-I抗体对麻风接触者发病风险预测的价值.方法:采用UCP-LFA方法检测贵州59例麻风患者、87例家庭接触者和55例健康对照者的PGL-I抗体水平.结果:麻风患者中PGL-I抗体阳性率为81.4%、麻风接触者为5.7%、健康对照人群为1.8%,差异有统计学意义(P<0.005).少菌型和多菌型PGL-I抗体阳性率分别为45.5%和89.4%,差异有统计学意义(P<0.005).BI阳性和BI阴性患者的PGL-I抗体阳性率分别为83%和0%,差异有统计学意义(P<0.005).结论:PGL-I IgM抗体水平对麻风发病风险有一定的预测作用.
