Fourteen (17.5%) controls with HCV(-)/RPR(+) had a non-reactive TPHA test. These represented 1.1% of all HCV-positive and 0.3% of all HCV-negative subjects (P<0.001). A significantly increased prevalence shown by false-positive tests for syphilis was observed in elderly HCV-seropositive ...
Dunseth et al. underlined the necessity of differentiation between analytical false-positive results of lues tests from clinical false-positive results. A positive syphilis IgG screen with negative RPR and T. pallidum particle agglutination assay (TP-PA) confirmatory testing could be considered an analy...

The RPR and TPHA remained negative in all patients throughout the follow up period. The results indicate that when the FTA ABS test is performed by the standard technique using a commercially prepared sorbent it may occasionally be reactive in patients with genital herpes. It is conceivable that...
RPR test.In this study BFPs were significantly more common in HCV positive patients compared to HCV-negative ones.Eosinophil abnormality can be considered as a predictor for BFP.Excessive BFPs must be considered in assessing the frequency of syphilis in a HCV-positive population and the importance...
Results of their serological follow-up were compared with those of HIV-negative clinic patients at the time of syphilis treatment. Failure was defined as lack of a fourfold drop in rapid plasma reagin (RPR) titre by 400 days after treatment or a fourfold increased titre between 30 and 400 ...

pallidum DNA and/or RNA were negative.A lack of demonstrable T. pallidum DNA or RNA suggests that blood donors with confirmed-positive results in STS are unlikely to have circulating T. pallidum in their blood and that that their blood is unlikely to be infectious for syphilis....
