was made. Once-weekly injections of penicillin G benzathine were given for 3 weeks. Two weeks after the patient began treatment, his symptoms had abated. Four months after the completion of treatment, repeat testing showed that the RPR titer had decreased to 1:4, and a repeat endoscopy showed...
AreactiveRPR test result is considered abnormal because antibodies were detected. This could either indicate a current syphilis infection, or the presence of a past infection that has been successfully treated. If an RPR test comes back as abnormal, a quantitative titer test will then be performed...
Patients with neurosyphilis without HIV infection or those with HIV infection who are on effective ART and who exhibit serologic (normalization of the serum RPR titer) and clinical responses after treatment do not need repeated CSF examinations. In HIV-infected patients, persisting CSF pleocytosis ma...
The RPR titer decreased more than twofold in 26.5% (18/68) and more than fourfold in 10.3% (7/68) before treatment. In the multivariable analysis, higher age (predicted monthly RPR relative change on the log2 scale 0.23/10 years [95% confidence interval [CI], 0.090–0.37]), history ...
Bei etwa 15% der Patienten mit primärer oder sekundärer Syphilis, die wie empfohlen behandelt werden, kommt es nicht zu einem 4-fachen Reagintiterabfall - das Kriterium, das verwendet wird, um die Reaktion 1 Jahr nach der Therapie zu definieren. Diese Patienten sollten klinisch und se...
Mother’s nontreponemal serologic titer remained low and stable (ie, serofast) before and during pregnancy and at delivery (VDRL <1:2; RPR <1:4) No evaluation is recommended in these cases. For more information, see the 2015 CDC guidelines for congenital syphilis treatment. ...
these assays may occasionally be positive in other disease states and are less specific than treponemal tests. These assays are also more likely than treponemal tests to be negative in primary syphilis and thus should not be used to rule out a diagnosis of primary syphilis. TheRPRtiter does, ...

Nontreponemal serology titer (VDRL, RPR) fails to decrease by at least 75% or more after 1 year RPR titer of greater than 1:32. Monitoring is recommended for RPR titers of 1:32 or less[115][126] Neurosyphilis and HIVhave a strong and close association with each other. CSF abnormalities...
