Malignant syphilis in an immunocompetent female patient

Malignant syphilis is an uncommon manifestation of secondary syphilis, in which necrotic lesions may be associated with systemic signs and symptoms. Generally it occurs in an immunosuppressed patient, mainly HIV-infected, but might be observed on those who have normal immune response. Since there is an exponential increase in the number of syphilis cases, more diagnoses of malignant syphilis must be expected. We report a case in an immunocompetent female patient.

Oral syphilis: report of three cases and characterization of the inflammatory cells

Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum. This study reports 3 cases of syphilis and highlights the importance of identifying oral lesions for its final diagnosis. Case 1: a 48-year-old male patient presented with a bleeding ulcer in the lower lip. Overall clinical examination revealed patchy alopecia and skin target lesions. Case 2: a 61-year-old male patient presented with white spots on the lateral tongue and nodules on the dorsum of the tongue. Overall clinical examination showed erythematous target lesions on the abdomen, forearm, palms of the hand, and soles of the feet. Case 3: a 17-year-old male patient presented with an ulcerated lesion on the tongue and lymph node involvement. The following serologic tests were requested: Venereal Disease Research Laboratory, fluorescent treponemal antibody-absorption, anti-HIV-1 and anti-HIV-2, and anti-hepatitis C virus. An incisional biopsy revealed epithelial hyperplasia associated with intense and diffuse mononuclear inflammatory cell infiltration consisting mainly of plasma cells, in a perivascular and perineural distribution. The final diagnosis in the 3 patients was syphilis. Treatment consisted of 1 weekly dose of penicillin (2.4 million units, intramuscular) for 2 or 3 weeks. Immunohistochemical reactions for XIIIa, CD3, CD20, CD68, CD163, S100, CD1a, CD11c, CD83, CD138, and CD208 were performed. Clinicians should be familiarized with oral syphilis lesions in order to be able to diagnose this emerging infectious disease of variable clinical presentation.

Oropharyngeal lesions and cervical lymphadenopathy: syphilis is a differential diagnosis that is still relevant

Syphilis (lues), a chronic infectious disease caused by Treponema pallidum, has been increasing in incidence during the last few years. Therefore, while clinically it is often not suspected, syphilis is increasingly becoming a differential diagnosis in routine pathology.

Occurrence, risk factors, diagnosis and treatment of syphilis in the prospective observational Swiss HIV Cohort Study

Background: Annual syphilis testing was reintroduced in the Swiss HIV Cohort Study (SHCS) in 2004. We prospectively studied occurrence, risk factors, clinical manifestations, diagnostic approaches and treatment of syphilis. Methods: Over a period of 33 months, participants with positive test results for Treponema pallidum hemagglutination assay were studied using the SHCS database and an additional structured case report form. Results: Of 7244 cohort participants, 909 (12.5%) had positive syphilis serology. Among these, 633 had previously been treated and had no current signs or symptoms of syphilis at time of testing. Of 218 patients with newly detected untreated syphilis, 20% reported genitooral contacts as only risk behavior and 60% were asymptomatic. Newly detected syphilis was more frequent among men who have sex with men (MSM) [adjusted odds ratio (OR) 2.8, P < 0.001], in persons reporting casual sexual partners (adjusted OR 2.8, P < 0.001) and in MSM of younger age (P = 0.05). Only 35% of recommended cerebrospinal fluid (CFS) examinations were performed. Neurosyphilis was diagnosed in four neurologically asymptomatic patients; all of them had a Venereal Disease Research Laboratory (VDRL) titer of 1:≥32. Ninety-one percent of the patients responded to treatment with at least a four-fold decline in VDRL titer. Conclusion: Syphilis remains an important coinfection in the SHCS justifying reintroduction of routine screening. Genitooral contact is a significant way of transmission and young MSM are at high risk for syphilis. Current guidelines to rule out neurosyphilis by CSF analysis are inconsistently followed in clinical practice. Serologic treatment response is above 90% in the era of combination antiretroviral therapy.

Effectiveness of interventions to improve screening for syphilis in pregnancy: a systematic review and meta-analysis

About 2·1 million pregnant women have active syphilis every year. Without screening and treatment, 69% of these women will have an adverse outcome of pregnancy. The objectives of this study were to review the literature systematically to determine the effectiveness of screening interventions to prevent congenital syphilis and other adverse pregnancy outcomes.

Assessment of a real-time PCR test to diagnose syphilis from diverse biological samples

OBJECTIVES: To investigate the contribution of a real-time PCR assay for the detection of Treponema pallidum in various biological specimens with the secondary objective of comparing its value according to HIV status. METHODS: Prospective cohort of incident syphilis cases from three Swiss hospitals (Geneva and Bern University Hospitals, Outpatient Clinic for Dermatology of Triemli, Zurich) diagnosed between January 2006 and September 2008. A case-control study was nested into the cohort. Biological specimens (blood, lesion swab or urine) were taken at diagnosis (as clinical information) and analysed by real-time PCR using the T pallidum 47 kDa gene. RESULTS: 126 specimens were collected from 74 patients with primary (n = 26), secondary (n = 40) and latent (n = 8) syphilis. Among primary syphilis, sensitivity was 80% in lesion swabs, 28% in whole blood, 55% in serum and 29% in urine, whereas among secondary syphilis, it was 20%, 36%, 47% and 44%, respectively. Among secondary syphilis, plasma and cerebrospinal fluid were also tested and provided a sensitivity of 100% and 50%, respectively. The global sensitivity of T pallidum by PCR (irrespective of the compartment tested) was 65% during primary, 53% during secondary and null during latent syphilis. No difference regarding serology or PCR results was observed among HIV-infected patients. Specificity was 100%. CONCLUSIONS: Syphilis PCR provides better sensitivity in lesion swabs from primary syphilis and displays only moderate sensitivity in blood from primary and secondary syphilis. HIV status did not modify the internal validity of PCR for the diagnosis of primary or secondary syphilis.

Cochleovestibular Deficit as First Manifestation of Syphilis in a HIV-Infected Patient

We report the detailed documented case of a 57-year-old homosexual HIV-positive man with bilateral cochleovestibular deficits as a first symptom of syphilis infection in early stage II disease. As a morphological substrate, a strong enhancement of both inner ears and vestibulocochlear nerves were found on gadolinium-enhanced MR scans. The serological tests identified an active infection with Treponema pallidum. After a high-dose treatment with penicillin G and prednisolone, the auditory and vestibular functions and the MR morphology of the vestibulocochlear nerves and inner ears on both sides returned to normal.

Congential syphilis in Harris County, Texas, 1993--1996

The specific aims of this study were to: (1) To determine the incidence of congenital syphilis (CS) for the 1993-96 birth cohorts in Houston/Harris County, based on the newly revised 1989 CS surveillance definition in Houston/Harris County, Texas; (2) To study the distribution of selected variables listed in the Centers for Disease Control and Prevention (CDC) Congenital Syphilis Case Investigation and Report Form for the reported cases of CS; (3) To ascertain the relationships of maternal demographic factors, geographic distribution, and provision and utilization of prenatal care, associated with reported congenital syphilis delivery.^ This was a descriptive study analyzing reported cases of congenital syphilis in Houston/Harris, County, TX during the years 1993-96 using the data recorded on the CDC's Congenital Syphilis Case Investigation and Report forms. The population included infants delivered during 1993-96 who were diagnosed with congenital syphilis, using the revised 1990 criteria of the CDC. This study examined the risk factors associated with the occurrence of congenital syphilis in Harris County where the prevalence of maternal syphilis infection (13.7/100,000/1995) is high.

Oral syphilis: a series of 5 cases.

Syphilis is an infectious, usually sexually transmitted, disease caused by Treponema pallidum, subspecies pallidum. Because of the increasing prevalence in Europe during the past few years, dentists could be confronted with patients with oral manifestations of syphilis. Because oral lesions are highly contagious, it is vital to make the correct diagnosis quickly to initiate the proper therapy and to interrupt the chain of infection. We present the cases of 5 patients with syphilis-related oral lesions. These cases are representative because of their clinical presentation, age, and gender distribution and the diagnostic approach. The aim of the present report is to emphasize the importance of the dentist knowing and identifying syphilis in different stages to diagnose the disease and institute treatment at an early stage.

Case control study identifying the maternal risk factors for congenital syphilis in Texas: 1998--2001

Background. Congenital syphilis (CS) is the oldest recognized congenital infection in the world. CS infection can affect multiple organs and can even cause neonatal death. CS is largely preventable when maternal syphilis is treated in an adequate and timely manner. During the decade of the nineties, rates of CS in Texas have often exceeded the overall US rate. Few studies, with adequate sample sizes, have been conducted to determine the risk factors associated with CS while controlling for factors associated with adult (maternal) syphilis infection. Objective. To determine the current maternal risk factors for CS infection in Texas from 1998–2001. Methods. A total of 1083 women with positive serological tests for syphilis during pregnancy or at delivery were reported to, and assessed by, health department surveillance staff. Mothers delivering infants in Texas between January 1, 1998 and June 30, 2001 comprised the study population. Mothers of infants diagnosed with confirmed or presumptive CS (N = 291) were compared to mothers of infants diagnosed as non-cases (N = 792) to determine the risk factors for vertical transmission (while controlling for risk factors of horizontal transmission). Logistic regression analyses were conducted to determine the associated odds between selected maternal variables and the outcome of CS. Results. Among 291 case infants, 5 (1.7%), 12 (4.1%), 274 (94.2%) were classified as confirmed cases, syphilitic stillbirths, and presumptive cases, respectively. Lack of maternal syphilis treatment was the strongest predictor of CS: odds ratio (OR) = 199.57 (95% CI 83.45–477.25) compared to those receiving treatment before pregnancy, while women treated during their pregnancies were also at increased risk (OR = 6.67, 95% CI 4.01–11.08). Women receiving no prenatal care were more likely (OR = 2.77, 95% CI 1.60–4.79) to have CS infants than those receiving prenatal care. Single women had higher odds (OR = 1.90, 95% CI 1.10–3.26) than ever-married women. African-Americans (OR 0.91, 95% CI 0.37–2.23) and Hispanics (OR = 1.66, 95% CI 0.68–4.05) may be more likely to have a CS infant than non-Hispanic Whites. Conclusions. The burden of CS in Texas can be alleviated through the provision of quality health care services, particularly prenatal care and treatment for sexually transmitted diseases. ^
