BACKGROUND: Treponema pallidum subsp. pertenue (TPE) is the causative agent of yaws, a multi-stage disease, endemic in tropical regions of Africa, Asia, Oceania, and South America. To date, four TPE strains have been completely sequenced including three TPE strains of human origin (Samoa D, CDC-2, and Gauthier) and one TPE strain (Fribourg-Blanc) isolated from a baboon. All TPE strains are highly similar to T. pallidum subsp. pallidum (TPA) strains. The mutation rate in syphilis and related treponemes has not been experimentally determined yet...

A syphilis diagnosis is often aided by the detection of treponemal and non-treponemal antibodies. Automated treponemal antibody detection systems enable high-volume clinical laboratories to perform syphilis screening at a faster pace with lower labor costs. The Lumipulse G TP-N chemiluminescent immunoassay is an automated system that qualitatively detects IgG and IgM antibodies against Treponema pallidum antigens in human serum and plasma. To assess performance characteristics and workflow efficiency, the Lumipulse G TP-N assay was compared to the Bioplex 2200 Syphilis IgG multiplex flow immunoassay...

Syphilis is an infection caused by Treponema pallidum, mainly transmitted by sexual contact. Since 2001, primary and secondary syphilis rates started to rise, with an epidemic resurgence. The authors describe an exuberant case of secondary syphilis, presenting with annular and lichen planus-like lesions, as well as one mucocutaneous lesion. Physicians must be aware of syphilis in daily practice, since the vast spectrum of its cutaneous manifestations is rising worldwide.

A 44-year-old man with human immunodeficiency virus positivity developed cerebral gumma 6 months after appropriate therapy for secondary syphilis. It was surgically resected and histologically, Treponema pallidum (14b/f, a relatively rare strain type) was proven. A complete set of modern techniques was performed to depict rare complication of this classic disease.

This study aimed to determine whether a serological response could predict the normalization of cerebrospinal fluid (CSF) abnormalities at 6 months after treatment in human immunodeficiency virus (HIV)-negative neurosyphilis patients. A total of 123 neurosyphilis patients were recruited at baseline, 58 of these patients undergoing treatment, repeated CSF examinations and serological tests for syphilis at 6 months after treatment were included in the follow-up study. Before treatment, the CSF rapid plasma reagin (RPR) titer, CSF Treponema pallidum particle agglutination (TPPA) titer, CSF leukocyte count, and CSF protein concentration were correlated with both serum RPR and TPPA titers...

We compared the performance and ease of use for three high-throughput treponemal immunoassays: Phoenix Biotech Trep-Sure Total Antibody EIA, Siemens ADVIA® Centaur Syphilis Assay, and DiaSorin LIAISON® Treponema Assay. One thousand serum samples submitted for routine screening were used in this study. Each assay demonstrated comparable sensitivity, specificity, and percent agreement (98-100%) compared with Treponema pallidum particle agglutination (TP-PA). Thus, treponemal immunoassays are an acceptable alternative for syphilis screening or confirmatory testing...

BACKGROUND: Congenital syphilis (CS) is an infectious disease resulting from transplacental transmission of Treponema pallidum spirochetes from an infected mother to fetus during pregnancy. While uncommon, CS has shown an increased incidence in Canada and the United States since 2001 and 2012, respectively. CASE REPORT: We present the case of a 5-week-old female infant with blistering rash on the palms and soles. The infant displayed decreased movement of the left upper extremity, clinically consistent with Parrot pseudoparalysis...

The number of new syphilis cases in Brazil has risen alarmingly in recent years. However, there is limited data regarding syphilis prevalence in the Brazilian prison population. To facilitate the development of effective interventions, a cross-sectional study was undertaken to determine the prevalence of Treponema pallidum infection, active syphilis, and associated risk factors among Brazilian prisoners. We administered a questionnaire to a population-based sample of prisoners from 12 prisons in Central-West Brazil and collected sera for syphilis testing, from January to December 2013...

In 2015, the Centers for Disease Control and Prevention (CDC) and the American Academy of Ophthalmology (AAO) released clinical advisories on rising cases of ocular syphilis. We examined the association between eye disease and syphilis infection among primary care and sexually transmitted infection (STI) clinic patients attending an urban lesbian, gay, bisexual, transgender (LGBT) health center. We conducted a retrospective medical record review of all patients who underwent syphilis testing at Howard Brown Health between 1 January 2010 and 31 December 2015...

We are currently facing a worldwide epidemic of syphilis. Clinical manifestations that are rarely seen have been encountered, leading the dermatologist to confront unusual clinical conditions in daily practice. Erythema multiforme triggered by syphilis is very rare and is also seldom reported in the literature. We report a case of secondary syphilis in an HIV-positive patient, whose clinical, pathologic and serologic features were consistent with the diagnosis of erythema multiforme triggered by syphilis.

The incidence of co-infection with Treponema pallidum and human immunodeficiency virus (HIV) is increasing in developing and developed countries. The neurological complications of both infections occasionally occur simultaneously during a clinical course. We herein report the case of an HIV carrier with syphilitic meningomyelitis and subclinical optic neuropathy. The patient presumably had latent syphilis and slowly developed longitudinally extensive transverse myelitis (LETM). A cerebrospinal fluid examination confirmed the diagnosis of active neurosyphilis based on an elevated T...

BACKGROUND: The incidence of tertiary syphilis involvement in the spinal column with destructive bone lesions is very rare. It is difficult to establish the correct diagnosis from radiographs and histological examination alone. Limited data are available on surgical treatment to tertiary syphilitic spinal lesions. In this article, we report a case of tertiary syphilis in the lumbar spine with osteolytic lesions causing cauda equina compression. CASE PRESENTATION: A 44-year-old man who suffered with low back pain for 6 months and progressive radiating pain at lower extremity for 1 week...

Currently, there are three algorithms for screening of syphilis: traditional algorithm, reverse algorithm and European Centre for Disease Prevention and Control (ECDC) algorithm. To date, there is not a generally recognized diagnostic algorithm. When syphilis meets HIV, the situation is even more complex. To evaluate their screening performance and impact on the seroprevalence of syphilis in HIV-infected individuals, we conducted a cross-sectional study included 865 serum samples from HIV-infected patients in a tertiary hospital...
