Abstract:
Objective To explore the significance of RPR te st and Tp -IgM-Capture -ELISA in fol-lowing-up of early syphilis.Methods Sixty-one cases of primary syphilis with less than one-year course and 77cases of secondary syphilis were enr olled into the study.The patients we re followed up by RPR test and Tp -IgM-Capture -ELISAat intervals of three months for two years after treatment .Results By the end of 3,6,9,12,15,18,21and 24months,RPRtest became negative in 6.2%,31.5%,61.5%,83.8%,90.7%,92.3%,94.6%,and95.3%of patients,respectively.By the end of 3,6,9,12and 15months,Tp -IgM-Capture -ELISA became negative in 25.4%,56.5%,86.2%,97.1%and 100.0%of patients,respectiv ely.In primary syphilis the RPR test became nonreactive in 8.2%(3months after treatment ),31.1%(6months),57.4%(9months),75.4%(12months),83.6%(15months),85.2%(18months),and 100.0%(21months)of patients,and Tp -IgM-Cap-ture -ELISA in 45.9%(3months),85.2%(6months),98.4%(9months),100.0%(12months)of patients.In secondary syphilis RPRtest became n onreactive in 2.6%(3months after treatment ),28.6%(6months),58.4%(9months),81.8%(12months),84.4%(15months),88.3%(18months),90.9%(21months)and 92.2%(24months)of patients,and Tp -IgM-Capture -ELISAin 9.1%(3months),33.8%(6months),71.4%(9months),94.8%(12months)and 100.0%(15months)of patients.Tp -IgM-Capture -ELISA was found to be negative earlier than that of RPR test in all ca ses.No sero-resistant was shown in T p -IgM-Capture -ELISA.Conclusions Tp -IgM turns to negative in 12months after treatment for nearly all patie nts with early syphilis.Tp -IgM-Cap-ture -ELISA may be served as a useful t ool to follow up early syphilis patie nts after treatment.[
