If the TPPA/TPHA remains nonreactive more than 90 days after exposure to a known syphilis case (and no other exposures since that date) you can consider the CMIA to be a false positive. The presence of actual syphilis would have caused the TPHA to be reactive by now. thab July 9, 202...
All neonates with a reactive nontreponemal test should be followed serologically to monitor its resolution. If the nontreponemal test is nonreactive by the age of 6 months, no further evaluation or treatment is needed. If the neonate still has a reactive nontreponemal test, he is likely to be...
However, the RPR result was non-reactive when he retested a week later and therefore was not diagnosed with syphilis and did not get treated at that time. His most recent RPR titer was 1:16. HIV serology and other STD tests were all negative. His wife and his 3 kids were negative for...
Although her RPR test was nonreactive, she had positive confirmatory treponemal tests with reactive FTA-AB and TPPA, which support the diagnosis of syphilis. Ultimately, when presented with a high-risk patient with neurologic signs and symptoms and positive confirmatory syphilis testing, which are ...

Malignant syphilis is a rare presentation of secondary syphilis, originally described by Bazin in 1859 as a nodular variant of syphilis. With the increase in the incidence of HIV infection, the morbidity as well as the frequency of this disease has increased[12]. It usually occurs from 6 weeks...
Independent of the HIV status, 30.5% (61/200) of the TP antibody positive samples were not detected by at least one of the assays after first testing, of which 42 were discrepant from the reference result (false non-reactive or indeterminate) in two or more assays (21%). Fourteen of th...

46 In this analysis, we rigorously defined neurosyphilis as a reactive CSF-VDRL, and syphilis without neurosyphilis as a nonreactive CSF-VDRL and CSF WBC≤5/μL. Participants were categorized as neurologically symptomatic if they complained of at least new mild photophobia, vision loss or gait ...
become non-reactive. After treatment, titres generally decline and in most immunocompetent individuals become non-reactive within 6 months. However, up to 20% of individuals infected and correctly treated show persistently reactive NTTs low titre results.53,54False-positive results with this test can...
