Syphilis continues to be an important epidemiologic problem. For a few years a steady increase in the incidence of this sexually transmitted disease has been observed. Advances in medical science obligate the doctor to use only such diagnostic and therapeutic approaches that are scientifically proven. Based on the European (IUSTI) and U.S. (CDC) guidelines, in this manuscript, we present some selected practical issues concerning diagnosis and treatment of syphilis. We truly hope that the present review will help all doctors taking care of syphilitic patients to systematize the current knowledge.

Purpose of review

People are living longer and healthier lives. In recent years, there has been a focus on recognition of ongoing sexual activity among older adults and leading from this, the potential for an increase in diagnoses of sexually transmitted infections (STIs). Data on STI rates, sexual behaviour and factors affecting susceptibility to STIs are discussed.

Recent findings

There is limited published literature in this field and few recent longitudinal studies of STI acquisition in people older than 50 years. Although there is evidence of an increase in incidence, STIs remain rare in older compared with younger populations. Compared with their heterosexual counterparts, older men who have sex with men are at higher risk of incident HIV and some other STIs. The HIV epidemic is ageing as a result of increasing life span and acquisition of HIV at older ages. Improved longevity, evolving societal norms and physiological changes may place older people at risk of HIV and other STIs.


Routine STI screening is not warranted in all older people. Education and prevention strategies for all people at greater risk of HIV, regardless of age are required. Age-appropriate interventions designed to impart knowledge and provide the requisite skills needed to reduce STI risk in older age would be beneficial.

Syphilitic Gumma

N Engl J of Medic Aug.14, 2014 V.371 P.667-667



  1. Cherniak and M. Silverman

A 45-year-old woman presented to an outreach clinic in rural Uganda with a 1-year history of a progressively enlarging ulcerated mass on the hard palate (Panel A). The mass had initially been painless but more recently had become painful and was causing difficulty in speaking and swallowing. She had received a diagnosis of cancer and was attempting to sell her home to pay for surgical resection. She had no history of syphilitic symptoms or treatment. The results on Treponema pallidum hemagglutination assay were positive for syphilis; nontreponemal testing was not locally available. Serologic analysis for human immunodeficiency virus was negative. Tertiary syphilis with an oral gumma was diagnosed. The patient was treated with three intramuscular injections of 2.4 million units of penicillin G benzathine at 1-week intervals. At follow-up 2 months after the end of treatment, there was resolution of the mass and symptoms (Panel B). In the oral cavity, gummas may occur as masses on the hard palate or tongue that frequently ulcerate….

Syphilis infection may potentiate transmission of human immunodeficiency virus (HIV). We sought to determine the extent to which HIV acquisition was associated with syphilis infection within an HIV preexposure prophylaxis (PrEP) trial and whether emtricitabine/tenofovir (FTC/TDF) modified that association.


The Preexposure Prophylaxis Initiative (iPrEx) study randomly assigned 2499 HIV-seronegative men and transgender women who have sex with men (MSM) to receive oral daily FTC/TDF or placebo. Syphilis prevalence at screening and incidence during follow-up were measured. Hazard ratios for the effect of incident syphilis on HIV acquisition were calculated. The effect of FTC/TDF on incident syphilis and HIV acquisition was assessed.


Of 2499 individuals, 360 (14.4%) had a positive rapid plasma reagin test at screening; 333 (92.5%) had a positive confirmatory test, which did not differ between the arms (FTC/TDF vs placebo, P = .81). The overall syphilis incidence during the trial was 7.3 cases per 100 person-years. There was no difference in syphilis incidence between the study arms (7.8 cases per 100 person-years for FTC/TDF vs 6.8 cases per 100 person-years for placebo, P = .304). HIV incidence varied by incident syphilis (2.8 cases per 100 person-years for no syphilis vs 8.0 cases per 100 person-years for incident syphilis), reflecting a hazard ratio of 2.6 (95% confidence interval, 1.6–4.4; P < .001). There was no evidence for interaction between randomization to the FTC/TDF arm and incident syphilis on HIV incidence.


In HIV-seronegative MSM, syphilis infection was associated with HIV acquisition in this PrEP trial; a syphilis diagnosis should prompt providers to offer PrEP unless otherwise contraindicated.

Worsening Epidemic of HIV and Syphilis Among Men Who Have Sex With Men in Jiangsu Province, China

Epidemics of human immunodeficiency virus (HIV) and syphilis among men who have sex with men (MSM) are major public health concerns in most parts of China. A dearth of information regarding the current trend of HIV in this hard-to-reach population in several regions including Jiangsu, coupled with the reemergence of syphilis, calls for an effort to understand the dynamics of the dual epidemic in this province.


To estimate the occurrence and burden of these 2 sexually transmitted diseases and the distribution of their potential sociobehavioral correlates among MSM in Jiangsu, 2 cohort studies were conducted in Yangzhou and Changzhou cities.


Among 839 participants, 48% were married, 51.7% had sex with women in the last 6 months, and 25.5% did not use condoms during their last anal intercourse. The observed incidence of HIV was 13.59 and 12.62 and that of syphilis was 7.33 and 13.25 per 100 person-years among the participants of Yangzhou and Changzhou, respectively. The baseline prevalence of HIV and syphilis was 16.0% and 29.9% in Yangzhou and 13.6% and 14.9% in Changzhou, respectively.


Considerably high incidence and prevalence of HIV and syphilis among participants and their potential bridging role in transmitting these infections to the general population in Yangzhou and Changzhou cities calls for urgent effective intervention strategies.

The Next Tsunami? HIV Spread in Asian Men Who Have Sex With Men

Over the past few years, human immunodeficiency virus (HIV) incidence has appreciably decreased in several countries [1]. However, in many parts of the world, HIV is spreading increasing rapidly among men who have sex with men (MSM) [2]. This trend of the epidemic becoming increasingly concentrated among MSM has been particularly marked in several urban epicenters throughout Asia in recent years, and in the current issue of Clinical Infectious Diseases, Yang et al describe a worsening epidemic of HIV and syphilis among MSM in 2 cities in Jiangsu Province in eastern China [3] . The authors found that HIV prevalence initially ranged between 13.6% and 16%, with syphilis prevalence ranging between 14.9% and 29.9%, but subsequent annualized HIV incidence was >12.5%. These rates are extremely high, and portend a worsening HIV/AIDS epidemic among Chinese MSM. Similar findings have been noted in several other recent studies from China [4–9] and nearby countries [10, 11], and contribute to a growing worrisome body of literature suggesting that AIDS in Asia is disproportionately becoming an MSM epidemic. The rapid spread of HIV among Asian MSM is particularly concerning because the majority of the world’s population lives in Asia, with an increasing number of individuals living in urban epicenters. Some MSM have female, as well as male partners, and/or inject drugs, so transmission outside their core group is highly likely. The potential for amplified transmission in these densely …

Sexually transmitted infections – Controversies and conundrums in screening, treatment and stigma

The five review topics in this issue highlight some of the key controversies in sexually transmitted infections (STIs), and their control.

The authors are from all corners of the world and work in different healthcare systems, but all have an awareness of the internationality of STIs, which do not conform to national boundaries.

A problem in one country can rapidly spread to other continents, requiring a world view of STI treatment and control, and international collaboration and support.

There are some major areas of concern: in men who have sex with men (MSM), there is a resurgent syphilis epidemic, hepatitis C in HIV-positive men has an annual incidence of transmission of 2–4% [1], and there is no decrease in HIV incidence in MSM; gonorrhoea has increased globally by 21% over 3 years [2] and multidrug, extensively drug-resistant and potentially untreatable
