Syphilis is a sexually transmitted disease caused by Treponema pallidum. The signs and symptoms of syphilis vary depending on which of the four stages it presents. The primary stage of syphilis classically presents with a painless ulcer (chancre). We report a case of the extragenital chancre on the nipple which is examined from skin biopsy and immunohistochemistry. This case showed that it is important to identify the special site’s pruritus erythema by pathology and serological examination.

AbstrakSifilis adalah penyakit menular seksual yang sangat infeksius, disebabkan oleh bakteri berbentuk spiral, Treponema pallidum subspesies pallidum. Penyebaran sifilis di dunia telah menjadi masalah kesehatan yang besar dengan jumlah kasus 12 juta pertahun. Infeksi sifilis dibagi menjadi sifilis stadium dini dan lanjut. Sifilis stadium dini terbagi menjadi sifilis primer, sekunder, dan laten dini. Sifilis stadium lanjut termasuk sifilis tersier (gumatous, sifilis kardiovaskular dan neurosifilis) serta sifilis laten lanjut. Sifilis primer didiagnosis berdasarkan gejala klinis ditemukannya satu atau lebih chancre (ulser). Sifilis sekunder ditandai dengan ditemukannya lesi mukokutaneus yang terlokalisir atau difus dengan limfadenopati. Sifilis laten tanpa gejala klinis sifilis dengan pemeriksaan nontreponemal dan treponemal reaktif, riwayat terapi sifilis dengan titer uji nontreponemal yang meningkat dibandingkan dengan hasil titer nontreponemal sebelumnya. Sifilis tersier ditemukan guma dengan pemeriksaan treponemal reaktif, sekitar 30% dengan uji nontreponemal yang tidak reaktifKata kunci: sifilis, Treponema pallidum, serologiAbstractSyphilis is a sexually transmitted disease that is highly infectious, caused by a spiral -shaped bacterium, Treponema pallidum subspecies pallidum. The spread of syphilis in the world has become a major health problem and the common, the number of 12 million cases per year. Infectious syphilis is divided into early and late-stage syphilis. Early-stage syphilis is divided into primary, secondary, and early latent. Advanced stage of syphilis include tertiary syphilis (gumatous, cardiovascular syphilis, and neurosyphilis) and late latent syphilis. Primary syphilis is diagnosed by clinical symptoms of the discovery of one or more chancre (ulcer). Secondary syphilis is characterized by the finding of localized mucocutaneous lesions or with diffuse lymphadenopathy. Latent syphilis without clinical symptoms of syphilis with a nontreponemal and treponemal reactive examination, history of syphilis therapy in nontreponemal test titer increased compared with the results of previous nontreponemal titers. Tertiary syphilis is found guma with reactive treponemal examination, approximately 30% of the non- reactive nontreponemal testKeywords: syphilis, Treponema pallidum, serologi

ABSTRACTSyphilis rates in much of the world are now at their highest levels in almost three decades, and new approaches to controlling syphilis, including diagnostic tests with shorter window periods, are urgently needed. We compared the sensitivity of syphilis serological testing using the rapid plasma reagin (RPR) test with that of the combination of serological testing and an experimental 23S rRNATreponema pallidumreal-time transcription-mediated amplification (TMA) assay performed on rectal and pharyngeal mucosal swabs.T. pallidumPCR assays for thetpp47gene were performed on all TMA-positive specimens, as well as specimens from 20 randomly selected TMA-negative men. A total of 545 men who have sex with men (MSM) who were seen in a sexually transmitted disease clinic provided 506 pharyngeal specimens and 410 rectal specimens with valid TMA results. Twenty-two men (4%) were diagnosed with syphilis on the basis of positive RPR test results and clinical diagnoses, including 3 men with primary infections, 8 with secondary syphilis, 9 with early latent syphilis, 1 with late latent syphilis, and 1 with an unstaged infection. Two additional men were diagnosed based on positive rectal mucosal TMA assay results alone, and both also tested positive by PCR assay. At least 1 specimen was TMA positive for 12 of 24 men with syphilis (sensitivity, 50% [95% confidence interval [CI], 29 to 71%]). RPR testing and clinical diagnosis were 92% sensitive (95% CI, 73 to 99%) in identifying infected men. Combining mucosal TMA testing and serological testing may increase the sensitivity of syphilis screening in high-risk populations.

A rapid test based on an immunochromatography assay - Determine™ Syphilis TP (Abbott Lab.) for detecting specific antibodies to Treponema pallidum was evaluated against serum samples from patients with clinical, epidemiological and serological diagnosis of syphilis, patients with sexually transmitted disease other than syphilis, and individuals with negative serology for syphilis. The Determine™ test presented the sensitivity of 93.6%, specificity of 92.5%, and positive predictive value and negative predictive value of 95.2% and 93.7%, respectively. One serum sample from patient with recent latent syphilis showed a prozone reaction. Determine™ is a rapid assay, highly specific and easy to perform. This technique obviates the need of equipment and its diagnostic features demonstrate that it may be applicable as an alternative assay for syphilis screening under some emergency conditions or for patients living in remote localities.

Abstract Syphilis is a systemic infection caused by Treponema Pallidum spirochete, which is considered to be the main sexually transmitted disease. The genital ulcerations and local inflammation found in syphilis are favouring factors involved in transmitting the HIV infection. Recent data suggests that individuals suffering from other sexually transmitted diseases are 3 to 5 times more exposed to developing HIV infection. On the other hand, simultaneous HIV infection may worsen the syphilis evolution. In the light of this data we present the case of a patient with syphilis-HIV coinfection recently diagnosed and we will summarize the clinical and evolutive features of the syphilis-HIV coinfection.

This study evaluated the performance characteristics of a new research use transcription-mediated amplification (TMA) assay for detection of ribosomal RNA from Treponema pallidum (Tp). Analytical sensitivity determined using dark field quantitated Tp was 1.4 organisms/ml (95% CI: 0.7-6.33). Dilution of Tp IVT RNA in STM yielded 100% positivity (n=3) at 10 copies/ml (4 copies/reaction). Analytical specificity testing of non-target microorganisms (N=59), including the closely related non-syphilis treponemes T. denticola and T. phagedenis, yielded 0% positivity. TMA testing of mucosal swab specimens collected from men who have sex with men (MSM) attending a sexually transmitted disease clinic yielded 1.8% (17/944) TMA positive results. A collection of 56 serum specimens obtained from a separate cohort of patients with known rapid plasma reagin (RPR) status and syphilis clinical diagnosis were 19.6% (11/56) TMA positive overall, 29.7% (11/37) positive among subjects with syphilis diagnosis, including 8 (36.3%) of 22 persons with primary or secondary syphilis, 2 (20%) of 10 persons with early latent syphilis and 1 (20%) of 5 persons with late latent or unstaged syphilis. None (0%) of 18 RPR positive sera from patients with a history of treated syphilis was TMA positive. These results show TMA is an analytically sensitive and specific method for detection of Tp rRNA and is compatible with serum specimens in addition to pharyngeal and rectal mucocutaneous swab specimens. Automated real time TMA testing for T. pallidum may be useful as an adjunctive method with serology for screening and diagnostic testing of selected patient populations for syphilis.
