Late latent mucinous syphilis mimicking connective tissue disease

As evidenced by the Centers for Disease Control and Prevention (CDC) statistics, syphilis is yet again on the rise. It is known as the great mimicker because of its variable symptoms and how frequently it can be confused with other diseases. The different stages of syphilis (primary, secondary, latent, late latent and tertiary) are discussed. We describe a new histopathologic pattern of syphilis, one that mimics connective tissue disease and can represent a diagnostic pitfall. In this time and age, when syphilis is rising especially among the men who have sex with men subgroup, it is important to keep a high index of suspicion of syphilis even when clinically and histopathologically the findings on first glance may not appear characteristic.     

Estimates of primary and secondary syphilis rates in persons with HIV in the United States, 2002

BACKGROUND: In the United States, there is a high rate of HIV coinfection in persons with syphilis. GOAL: The goal of this study was to estimate the rate of primary and secondary (P&S) syphilis in persons living with HIV in the United States in 2002. STUDY: We approximated the number of new cases of P&S syphilis in HIV-infected persons and divided this by the estimated number of persons living with HIV. Values for the calculations were obtained from national syphilis and HIV/AIDS surveillance reports and other published sources. RESULTS: We estimated the rate of new cases of P&S syphilis at 186 per 100,000 persons living with HIV in 2002, 25 per 100,000 HIV-infected women, 60 per 100,000 HIV-infected men who have sex with women only, and 336 per 100,000 HIV-infected men who have sex with men. Of the 6862 reported cases of P&S syphilis in 2002, an estimated 1718 (25%) occurred in persons coinfected with HIV. CONCLUSIONS: The estimated rate of P&S syphilis in persons with HIV is considerably higher than that of the general population. These findings highlight the importance of providing sexually transmitted disease prevention and control services to HIV-infected persons.     

An outbreak of early syphilis: cases from North Manchester General Hospital

OBJECTIVES: To describe the features of an outbreak of early syphilis in North Manchester. METHODS: Retrospective KC60 and case note review. RESULTS: In a 25 month period, 10 cases of primary, 22 of secondary, and nine cases of early latent syphilis were diagnosed. 39 were homosexual or bisexual men, 20 being co-infected with HIV. Most infections were acquired locally and in 19/41 cases oral sex was the only risk factor. High rates of unprotected anal sex were reported among the homosexual men and co-infection with other STIs was common. CONCLUSION: This outbreak will facilitate the spread of HIV in the homosexual male population. Unsafe sexual practice is common and the perception that oral sex is "safe" needs revisiting. Delays in accessing GUM clinic appointments must be addressed as part of the control strategy.     

Surfing with spirochaetes: an ongoing syphilis outbreak in Brighton

BACKGROUND/OBJECTIVES: There has been a recent shift in the epidemiology of early syphilis in the developed world with sporadic outbreaks on a historic low level of background disease. Here we describe an ongoing outbreak of syphilis in Brighton. METHODS: Data collected on all patients with a diagnosis of early infectious syphilis at Brighton GUM clinic. RESULTS: 30 cases of early syphilis were diagnosed over a 25 month period beginning in July 1999. 28 were homosexual or bisexual men, giving a rate of 134 cases per 100 000 homosexual men. The cases reported a median of three sexual contacts (range 1-50) in the preceding 6 months and 77% had concurrent regular and casual partners. 83% of contacts were casual and untraceable. Over one third (11) of these cases reported oral sex as their only risk factor for syphilis acquisition and were unaware of this transmission route. 70% were diagnosed with primary or secondary infection, the remaining 30% being asymptomatic with early latent infection. Eight of the cases were HIV positive and a further eight remain untested for HIV. At least one concurrent STI was found in 40% of cases. Regular outbreak control meetings, involving relevant healthcare professionals, were held to plan appropriate interventions. CONCLUSION: The high rate of casual and untraceable contacts in this outbreak suggest that alternative control measures are necessary, including on-site testing and further health education regarding the oral transmission of syphilis. Continued vigilance for syphilis is essential, especially in those patients who are HIV positive.     

Mucocutaneous manifestations of congenital syphilis in the neonate: A review of a surging disease

Syphilis is an infection caused by Treponema pallidum. It is most commonly acquired through sexual transmission, although it can also be transmitted vertically across the placenta, resulting in congenital syphilis. Even with improved public health measures, testing, and treatment capabilities, primary, secondary, and congenital syphilis have all surged since 2012. Given this marked increase in both incidence and prevalence, here we present a comprehensive review of the clinical presentation, treatment, and management of congenital syphilis, with particular consideration given to the mucocutaneous manifestations of the disease in neonates.     

Late syphilis mimicking a pseudolymphoma of the skin

After a period of declining incidence of syphilis in most of Western Europe until the late 1990s, reports about an increasing trend have been published recently. In contrast to the rising incidence of early syphilis, cases of late (tertiary) syphilis are rarely seen in developed countries. In this report, we describe a 54-year-old patient with infiltrated erythematous plaques on his forehead and neck that histologically revealed a dense lymphocytic cell infiltrate with numerous plasma cells. The serologic examination was characteristic of syphilis and in conjunction with the clinical presentation and the patient's history led to the diagnosis of tertiary syphilis. The diagnosis of this late stage of syphilis can be difficult as clinical pictures can be misleading. Peculiar skin lesions should always remind clinicians of this infectious disease which has still to be considered in differential diagnoses in dermatology.     

HIV prevalence in patients with syphilis, United States

BACKGROUND: Among persons with a sexually transmitted disease (STD), the proportion who are also infected with HIV is a major factor influencing the public health impact of that STD on HIV transmission. GOAL: To assess HIV infection in persons with syphilis in the United States. STUDY DESIGN: A systematic literature review was conducted of U.S. studies with HIV seroprevalence data in patients with syphilis. RESULTS: Thirty studies were identified and analyzed. The median HIV seroprevalence in men and women infected with syphilis was 15.7% (interquartile range [IQR]: 13.6-21.8%), among men was 27.5% (23.1-29.6%), and among women was 12.4% (8.3-20.5%). Median odds ratios for men and women, men only, and women only were 4.5, 8.5, and 3.3, respectively. Seroprevalences among men who have sex with men (MSM) and injecting drug users (IDU) ranged from 64.3-90.0% and 22.5-70.6%, respectively. CONCLUSIONS: Despite substantial variability, HIV seroprevalence is high among patients with syphilis in the United States, identifying them as a critical target group for HIV prevention efforts.     

A consequence of the syphilis epidemic among men who have sex with men (MSM): neurosyphilis in Los Angeles, 2001-2004

OBJECTIVES: To describe the epidemiology and clinical findings of neurosyphilis (NS) cases diagnosed during the current syphilis epidemic occurring predominantly among men who have sex with men. METHODS: Syphilis cases reported to the health department were reviewed for diagnosis of NS, cerebrospinal fluid venereal disease research laboratory results, and/or treatment for NS. RESULTS: During 2001-2004, 7083 cases of syphilis were diagnosed in Los Angeles. One hundred nine cases of confirmed or probable NS occurring among persons aged 19 to 65 years were identified during this period (1.5%). Symptomatic NS was present in 1.2% of reported syphilis cases (86 of 7083). NS cases were inclusive of 71 (65%) men who have sex with men. Forty-two (49%) of the symptomatic NS cases occurred during secondary (N = 28) or early latent (N = 14) syphilis. Sixty-eight percent (N = 74) of the NS cases were human immunodeficiency virus (HIV)-positive. The estimated incidence of symptomatic NS among HIV-infected persons with early syphilis was 2.1% as compared with 0.6% among HIV-negative persons. CONCLUSION: Providers should maintain a high index of suspicion for NS among patients with syphilis, particularly those with HIV infection.     

Rapid public health interventions in response to an outbreak of syphilis in Los Angeles

BACKGROUND: Despite national ambitions to eliminate syphilis, occasional outbreaks continue to occur in many areas of the United States. GOAL: The goal of the study was to describe and evaluate the public health interventions in response to an outbreak of syphilis in Los Angeles County among men who have sex with men. STUDY DESIGN: Reported cases of primary, secondary, and early latent syphilis that occurred during an outbreak period from December 1999 to September 2000 were included in the study. The outbreak components of provider awareness, active surveillance, community-based organization recruitment, media campaign, community-outreach education and screening, and a correctional facility intervention were described. Screening results were reviewed, sexually transmitted disease (STD) hotline calls were counted, and a street-intercept survey was conducted. RESULTS: A multifaceted outbreak response was initiated in March 2000. Of the 89 outbreak cases identified, 40% were detected by HIV/AIDS early intervention providers and 26% by private clinicians or health maintenance organizations. Other case identification sources included public STD clinics (10%), STD program case-management contacts (7%), mobile van screening (7%), and correctional facility screening (10%). Screening at high-risk venues detected a syphilis prevalence of <1% and an HIV prevalence of 6%. Weekly calls to the STD hotline increased 600% during the outbreak, and 80% of surveyed individuals cited the media as the source of their awareness of syphilis. CONCLUSIONS: A multifaceted outbreak response was launched to react to an outbreak of syphilis among men who have sex with men. Prompt provider awareness and a preexisting network of HIV/AIDS providers aided case detection. Although the effectiveness of the response could not be scientifically determined, the diverse components of the response were associated with a faster decline in the outbreak than would have been expected. After 3 months, 89 cases had been identified. Outbreak preparedness should include a focus on communities of men who have sex with men, because the reintroduction of syphilis in this population may threaten national efforts toward syphilis elimination.     

Seronegative secondary syphilis in an HIV-infected patient

Recently, increased rates of syphilis among gay men have been observed in American and European cities. It is important to establish the diagnosis because syphilis facilitates HIV transmission during the primary and secondary stages when sores are open on the skin. However the diagnosis can present a dilemma as negative reactions to serological tests may be observed in AIDS patients. We report here such a case in which the diagnosis was established on dark field examination.     

Contact-tracing outcomes among male syphilis patients in Fulton County, Georgia, 2003

OBJECTIVES: Contact tracing may be less effective in populations with casual sex partners such as male syphilis patients who report sex with men; this opinion is widely held, but few quantitative comparisons are available. GOAL: The goal of this study was to compare contact-tracing outcomes among male syphilis patients reporting sex with men (MSM) or with women only (MSWO). STUDY DESIGN: The authors conducted a record review of cases of early syphilis among MSM and MSWO comparing contact-tracing outcomes. RESULTS: Interviews of MSM case-patients resulted in higher mean numbers of contacts named and located per case than interviews of MSWO. Mean numbers of contacts of MSM and MSWO diagnosed with syphilis per case were not significantly different. The mean number of unlocatable sex partners per case was slightly higher for MSM than MSWO. CONCLUSION: This study comparing contact tracing by the same trained health department personnel demonstrated that outcomes of contact tracing were similar for MSM and MSWO.     

An epidemiological study of syphilis incognito, an emerging public health problem in Greece

BACKGROUND: Syphilis incognito is a subtype of latent syphilis (early or late) characterized by no signs or symptoms of primary or secondary syphilis and diagnosed by positive serologic results for syphilis during routine screening. OBJECTIVE: To study the epidemiological characteristics, causes, and implications of syphilis incognito in Greece. PATIENTS AND METHODS: All new adult patients diagnosed as having syphilis in Andreas Sygros Hospital for Skin and Venereal Diseases, Athens, Greece, from 1989 through 1996 were studied prospectively and retrospectively (history, physical examination, serologic tests, cerebrospinal fluid examination, and imaging) to determine the stage of their disease. The epidemiological, clinical, and serologic characteristics of patients with syphilis incognito were recorded and analyzed. RESULTS: During the 8-year period, 711 new syphilis cases were detected; of these, 480 cases (67.5%) fulfilled the definition criteria of syphilis incognito. The male-female ratio was 1.8:1. Patients with syphilis incognito were most commonly heterosexual, had a median socioeconomic status, and were aged 20 to 39 years, and their conditions were diagnosed during routine screening for syphilis (prenatal care, hospital admission, or blood donation). However, the number of syphilis incognito cases appeared to decline during the period studied. CONCLUSIONS: The incidence of syphilis in Greece has decreased dramatically, following the trends in western Europe. The most common form of syphilis is syphilis incognito, affecting adults who are older and have a higher socioeconomic status than those in the past. Improved hygiene and wide use of antibiotics that minimize or abolish symptoms of early disease may have contributed to the frequency of syphilis incognito in recent years. Screening of asymptomatic persons, especially those at high risk, should continue and be reenforced to prevent the devastating consequences of unrecognized and untreated syphilis.

The erythrocyte sedimentation rate in syphilis.

The erythrocyte sedimentation rate was studied in 520 men and 202 women with syphilis. It was raised in 66-6 per cent. of sero-negative primary cases, 80 per cent. of sero-positive cases, 100 per cent. of secondary cases, 80 per cent. of early latent cases, and 73-9 per cent. of late latent cases. It was also raised in sixteen out of seventeen cases of neurosyphilis and in all eleven cases of cardiovascular syphilis. It was concluded that the ESR had little place in the management of syphilis in general, but could be helpful in the post-treatment follow-up of late syphilis.     

AIDS mortality may have contributed to the decline in syphilis rates in the United States in the 1990s

BACKGROUND: The mortality associated with AIDS among men may have had an influence on primary and secondary syphilis trends among men in the United States, through the loss of men at high risk for acquisition or transmission of syphilis in this population and/or by prompting safer sexual behaviors in response to the threat of AIDS. GOAL: The goal of this study was to examine the association between AIDS mortality rates and primary and secondary syphilis incidence rates among men in the United States from 1984 to 1997. STUDY DESIGN: We used a fixed-effects regression analysis of state-level AIDS mortality rates and primary and secondary syphilis incidence rates for men. RESULTS: Our analysis showed a significant association between higher AIDS mortality and lower rates of syphilis incidence, after we controlled for confounding factors. Our model estimates suggested that every 20 AIDS deaths per 100,000 adult men are associated with declines of about 7% to 12% in syphilis incidence rates among men. CONCLUSION: Increases in AIDS-associated mortality may have accounted for one-third to one-half of the decline in syphilis rates among men in the early 1990s. Recent declines in AIDS mortality in the United States may have contributed to the recent outbreaks of syphilis, particularly among men who have sex with men. Our findings underscore the importance of providing STD prevention services to men with HIV infection and the need for STD surveillance in communities at risk for syphilis outbreaks.     

Female-to-female transmission of syphilis: a case report

BACKGROUND: The rate of transmission of HIV and other sexually transmitted infections from female to female is a matter of debate. Sexually transmitted disease among lesbians and female bisexuals is usually associated with sexual contact with men or intravenous drug use. There is little evidence that female-to-female transmission of syphilis can occur. GOALS: To demonstrate that female-to-female transmission of syphilis can occur through oral-genital sex. STUDY DESIGN: Case report of syphilis transmission from one female to another through oral-genital sex. CONCLUSION: Female-to-female transmission of syphilis can occur through oral-genital sex.     

Online syphilis testing--confidential and convenient

OBJECTIVE: In response to the current syphilis epidemic among men who have sex with men, the San Francisco Department of Public Health sought to increase syphilis testing by offering testing in nonclinical settings. GOAL: The goal of this study was to collaborate with a community-based organization, Internet Sexuality Information Services, Inc. (ISIS), to design an innovative, confidential, online testing service for syphilis. STUDY: The service, called STDTest.org, was launched in June 2003. The web site allows people to print out a laboratory requisition slip, have their blood drawn, and receive their test results online. RESULTS: During the first year, 218 tests were performed and 13 persons had reactive serologies. Six patients were diagnosed with a new syphilis infection and treated. CONCLUSIONS: Online syphilis testing offers a free and convenient alternative to getting tested at the San Francisco municipal sexually transmitted disease clinic and an additional means for detecting syphilis cases.     

Evaluation of syphilis reactor grids: optimizing impact

BACKGROUND: A syphilis reactor grid (SRG) is an administrative tool based on the sex, age, and serologic titer of persons with reactive serologic tests for syphilis (reactors) that is used by Sexually Transmitted Disease program staff to prioritize follow-up investigations of persons who may have syphilis. The National Plan to Eliminate Syphilis from the United States recommends that state and local health departments regularly evaluate the effectiveness of their SRGs. However, there are limited methods for SRG evaluation that are feasible for sexually transmitted disease programs. GOAL: To evaluate the sensitivity and predictive value of five currently used SRGs. STUDY DESIGN: Comparative evaluation of five SRGs in four different populations. RESULTS: The percentage of true syphilis cases not assigned to an investigation by an SRG (missed cases) was dependent on syphilis prevalence among reactors and on the SRG. The percentage of reactors assigned to an investigation by an SRG that were not true cases was primarily dependent on syphilis prevalence among reactors, not SRG design. Cases missed by SRGs were predominantly men aged 30 to 50 years and women aged 20 to 40 years who had low or intermediate serologic titers. CONCLUSION: Monitoring the prevalence of syphilis among reactors is critical because in areas with high prevalence, most SRGs miss a substantial number of cases, and in areas with low prevalence, some SRGs can reduce unnecessary investigations.
