The recombinant DNA-derived Treponema pallidum membrane protein TmpA, purified from Escherichia coli K-12, was used in an enzyme-linked immunosorbent assay (ELISA) to evaluate its suitability in a screening test for syphilis and to monitor the effect of antibiotic treatment. The sensitivity of the TmpA ELISA was 76% for primary syphilis, 100% for secondary syphilis, and 98% for early latent syp...

BACKGROUND The epidemiology of incident syphilis infection among HIV-1-infected men who have sex with men (MSM) largely remains unknown. METHODS The incidence and risk factors for incident syphilis (positive TPHA and RPR> = 1:8) among HIV-1-infected MSM who visited a large HIV clinic in Tokyo for the first time between 2008 and 2013 were determined, using clinical data and stored blood sample...

INTRODUCTION The aim of this study was to determine factors associated with lack of serological response (LSR) to treatment of syphilis among HIV-infected subjects. MATERIALS AND METHODS Retrospective, longitudinal study on HIV-infected subjects diagnosed and treated for syphilis and with an assessable serological response between 1 January 2004 and 15 September 2013. LSR was defined as a <4-...

Two new enzyme-linked immunosorbent assays (ELISA), one for the measurement of immunoglobulin G (IgG) (Captia Syphilis-G) and one for the measurement of IgM (Captia Syphilis-M), were evaluated for detecting antibodies to Treponema pallidum. Serum samples from 169 patients, 96 with various stages of untreated syphilis, 63 with treated syphilis, and 10 who were noninfected, were investigated. All...

The question whether third-generation syphilis does occur has in the past been the subject of much debate and controversy. The following criteria laid down by Fournier (1891) and Finger (1900) still provide the yardstick by which third-generation syphilis is judged: (1) Acquired syphilis must be demonstrated in the grandmother and preferably also in the grandfather. (2) Pre-natal as distinguish...

BACKGROUND Concomitant syphilis and human immunodeficiency virus (HIV) infection is increasingly frequent in industrialized countries. METHODS From a large hospital cohort of HIV-infected patients followed up in the Paris area between 1998 and 2006, we examined the effect of early syphilis on plasma HIV-1 RNA levels and CD4 cell counts. We compared 282 HIV-1-infected men diagnosed as having i...

Abstract The recent resurgence of infectious syphilis across many high-income countries has been accompanied by a shift in demographics, including infections increasing among women reproductive age. Consequently, several are reporting cases congenital syphilis, disease associated with range health and social consequences that is treatable, preventable, could be eliminated. To prevent the large ...

As of late, the incidence of congenital syphilis in the United States is increasing. Each new case represents a failure of preventing, diagnosing, and treating syphilis in pregnant women. Pediatricians should confirm that all women have received adequate screening for and management of syphilis during pregnancy. Congenital syphilis is easily treatable but may be a diagnostic challenge with high...

Endemic (nonvenereal) syphilis is relatively common in nonindustrialized regions of the world. We describe a case of local transmission in Canada and review tools available for confirming a diagnosis. Improved molecular tools and global clinical awareness are needed to recognize cases of endemic syphilis imported to areas where it is not normally seen.
