Neurosyphilis, ocular syphilis, and otosyphilis are serious manifestations that can occur at any stage of infection. Treponemal or nontreponemal serological studies are used for screening, and the diagnosis is typically made based on clinical assessment and the interpretation of syphilis serologies. ...
Here are some examples of common serologic patterns and their interpretation: EIA reactive, RPR reactive, TP-PA reactive This is consistent with syphilis infection. If the patient has previously received treatment and the RPR titre is declining, it may be consistent with treated syphilis. EIA react...
Patienten mit Neurosyphilis ohne HIV-Infektion oder solche mit HIV-Infektion, die eine wirksame ART erhalten und nach der Behandlung ein serologisches (Normalisierung des Serum-RPR-Titers) und klinisches Ansprechen zeigen, benötigen keine wiederholten Liquoruntersuchungen. Bei HIV-infizierten Pa...
there is much difficulty in interpretation ofserologic testsdue to slow reaction, however high levels of relapse are also seen in these patients. It is thus encouraging that recent studies have given us new tools to help in the management of co-infected patients. There is a great importance in...
The patient had false-positive syphilis test results during 2 pregnancies, 25 and 22 years prior, based on a positive blood rapid plasma reagin (RPR) test result (titer, 1:2 [reference, nonreactive]) and negative fluorescent treponemal antibody (FTA-ABS) test result. On current ...

Result Interpretation of Rapid Plasma Reagin (RPR) Test Positive Result (Reactive):Clumping (Characteristic clumping ranging from marked and intense (reactive) to Reactive (R) slight but definite (minimally to moderately) reactive). Negative Result (Non-Reactive):No Clumping or slight roughness. ...
Nontreponemal tests (VDRL or RPR) may be performed on the neonate instead, as they utilize IgM antibodies, which do not cross the placenta.[14][44][64][65]Nontreponemal IgA and IgG maternal antibodies may passively cross the placental barrier, which reduces their sensitivity, but they are ...
Song et al. evaluated diagnostic methods for revealing syphilis in children. False-positive tests for syphilis were higher in the children’s group than in the infant’s group. The high false-positive rate of enzyme-linked immuno-sorbent assay (ELISA) could be caused by hemolysis. The RPR had...
