    The investigators report the case of a 44-year-old man who presented acutely and was found to have saccular aneurysm of the innominate artery, narrowed or totally occluded aortic arch arteries, and marked thickening of the thoracic aorta except for the wall behind the sinuses of Valsalva. The abdominal aorta was entirely normal. Results of the serologic test for syphilis were strongly positive. Because cardiovascular syphilis appears to be a disease that affects the vasa vasora and because these channels are limited to the thoracic aorta, the abdominal aorta is uninvolved, as demonstrated so nicely in the patient described in this case report. Because most patients with cardiovascular syphilis are much older than the patient described, it is unusual to see a perfectly normal abdominal aorta, as in the present patient. In conclusion, syphilis producing aneurysm of the innominate artery is unusual but is always associated with syphilitic involvement of the thoracic aorta.

    Syphilis is back since the beginning of this century. The epidemic affects mainly men having sex with men with a high proportion of HIV-infected patients. The classification of syphilis distinguishes early syphilis where patients are contagious (primary, secondary and early latent of less than one year) and late syphilis where patients are not (or less) contagious (late latent of more than one year and tertiary). The clinical presentation of syphilis has not changed. However, we must insist on the early forms of neurosyphilis, notably ophthalmic syphilis often under-diagnosed, as it affects the treatment. Serologic tests may be improved but are very helpful for the positive diagnosis and the follow-up after treatment. Treatment of early syphilis is based on one injection of benzathine benzyl penicillin G. Patients who have had syphilis must be regularly followed-up after treatment, as re-infections are common and are often asymptomatic.

    1983-01-01

    In recent years, marked increase in incidence of congenital syphilis has occurred throughout the world due to changes in social norms and development of penicillin-resistant strains. Early diagnosis plays an important role in congenital syphilis as the clinical manifestations may simulate many other conditions in the paediatric age group. The authors analyzed 52 cases of congenital syphilis admitted to the department of paediatrics, Chosun University Hospital, clinically and radiologically. Among them, 18 cases were born in this hospital and 34 cases were admitted from OPD, during the period of 8 years from January, 1975 to December, 1982. The results obtained were as follows; 1. In 28 of 34 cases (82%), the first clinical manifestations were below the age of 3 months. 2. Among the 52 cases, a male predominance was observed with a male to female ratio of 2 : 1. 3. The serologic test (VDRL) of the 52 studied cases showed reactive response in 49 cases (94%), and that of syphilitic mothers except 6 cases, reactive in all studied cases. 4. The major manifestations of the 52 cases were bone tenderness (12%) and swelling of the joints (7%) in skeletal system, hepatosplenomegaly (79%) and skin lesions (73%) in extraskeletal one. 5. The radiological skeletal changes were detected in 45 of 52 cases (87%), and the commonest findings were detected in 45 of 52 cases (87%), and the commonest findings were metaphysitis (83%) and periostitis (81%). The most characteristic type of metaphysitis were transverse trophic line (74%) and zone of rarefaction (65%). 6. The commonest bones to be affected were growing metaphyses of the long bones, particulary about the wrist and the knee. The order of frequency were radius (80%), uina (80%), tibia (77%), femur (69%) and humerus (40%)

    Syphilis, caused by the spirochete Treponema pallidum subspecies pallidum, continues to be a globally prevalent disease despite remaining susceptible to penicillin treatment. Syphilis vaccine development is a viable preventative approach that will serve to complement public health-oriented syphilis prevention, screening and treatment initiatives to deliver a two-pronged approach to stemming disease spread worldwide. Areas covered: This article provides an overview of the need for development of a syphilis vaccine, summarizes significant information that has been garnered from prior syphilis vaccine studies, discusses the critical aspects of infection that would have to be targeted by a syphilis vaccine, and presents the current understanding within the field of the correlates of protection needed to be achieved through vaccination. Expert commentary: Syphilis vaccine development should be considered a priority by industry, regulatory and funding agencies, and should be appropriately promoted and supported.

    Full Text Available Syphilis is an infectious disease caused by Treponema pallidum and has high rates of vertical transmission, which can reach 100% depending on the maternal disease and stage of pregnancy. The diagnosis of gestational syphilis is simple and its screening is required during the prenatal period. However, this disease still has a high prevalence, affecting two million pregnant women worldwide. The procedures performed in newborns with congenital syphilis represent costs that are three-fold higher than the ones spent with a baby without this infection. The treatment is generally carried out with penicillin and must be extended to sexual partners. Inadequate or lack of treatment of congenital syphilis can result in miscarriage, premature birth, acute complications and other fetal sequelae. KEYWORDS: Congenital syphilis. Treponema pallidum. Vertical transmission.

    As of late, the incidence of congenital syphilis in the United States is increasing. Each new case represents a failure of preventing, diagnosing, and treating syphilis in pregnant women. Pediatricians should confirm that all women have received adequate screening for and management of syphilis during pregnancy. Congenital syphilis is easily treatable but may be a diagnostic challenge with high morbidity and mortality.

  13. Auckland: city of syphilis?

    2016-12-16

    To briefly report on the large increase in cases of syphilis managed at Auckland Regional Sexual Health Service (ARSHS) in 2015. To raise awareness of syphilis as an emerging significant public health issue in Auckland. A search was conducted of the electronic patient management system at ARSHS for cases of syphilis diagnosed between 1st of January 2015 and 31st of December 2015. Those that fitted the Institute of Environmental Science and Research Ltd (ESR) case definitions for infectious syphilis were included and demographic, clinical and behavioural characteristics were described. One hundred and fifty-two cases of infectious syphilis were managed at ARSHS in 2015, which was a 78% increase from the previous year. The crude incidence rate was 9.5 cases per 100,000 head of population. As in previous years, the majority of cases were male (92%) and most of these were gay or bisexual men (GBM). Thirty-nine percent of cases were asymptomatic and 22% of cases were diagnosed with another STI. Twenty-eight percent of GBM were co-infected with HIV. While the overall number of heterosexual cases was small (n=35); there was a 3.8-fold increase from the numbers diagnosed in 2014 (n=9). The largest number of syphilis cases in recent decades was managed by the Auckland Regional Sexual Health Service in 2015. The increase in numbers is concerning as syphilis can enhance transmission and acquisition of HIV. Furthermore, other countries have noted increases in congenital syphilis cases when incidence in females has increased. It is important that all persons at risk of STI are tested for syphilis and that sexually active GBM in particular are tested regularly. Health professionals need to be made aware of who and when to test, and to refer or discuss any suspected cases with a specialist service as management of syphilis requires significant expertise.

    Full Text Available Joint involvement in syphilis has been considered as casuistry in recent years. At the same time, the high incidence of primary syphilis and the notified cases of late neurosyphilis may suggest that joint involvement in this disease is by no means always verified. Traditionally there are two forms of syphilitic arthritis: primary synovial (involving the articular membranes and sac and primary bone (involving the articular bones and cartilages ones. The paper describes the authors' clinical case of the primary bone form of articular syphilis in a 34-year-old man.

    Full Text Available Late congenital syphilis is a very rare clinical entity, and its early diagnosis and treatment is essential. Dental findings often provide valuable evidence for the diagnosis of late congenital syphilis. It occurs due to the transmission of the disease from an infected mother to her fetus through placenta. This long forgotten disease continues to effect pregnant women resulting in perinatal morbidity and mortality. Congenital syphilis is a preventable disease, and its presence reflects a failure of prenatal care delivery system, as well as syphilis control programs. We are reporting a case of late congenital syphilis with only Hutchinson′s teeth.

We report a case of 2 month old female infant who presented with runny nose, papulosquamous lesions over both palms and soles and perianal erosions since 1 month after birth. Cutaneous examination revealed moist eroded areas in the perianal region and fine scaly lesions over palms and soles. Radiograph of both upper limbs and limbs revealed early periosteal changes in lower end of humerus and lower end of tibia. Diagnosis of early pre-natal syphilis was confirmed by Child′s Serum Rapid Plasma Reagin Antibody test [S.RPR] being positive with 1:64 dilution while that of mother was 1:8.

    The objective of this article was to alert general practitioners (GPs) to the increase in ocular syphilis in the context of a worsening epidemic of syphilis among men who have sex with men (MSM). This study used a retrospective case review of ocular syphilis cases that presented to the Royal Victorian Eye and Ear Hospital from January 2015 to August 2016. Twelve patients (19 eyes) were identified, including 11 males. The mean age was 35 years, and seven men were identified as MSM. Two men were diagnosed with human immunodeficiency virus (HIV) infection at presentation. Blurred vision (n = 10) and/or floaters (n = 9) were the most common presenting symptoms. All patients had uveitis as the manifestation of the ocular involvement; however, redness and pain were not universally reported. GPs should be alert to the possibility of ocular syphilis at the time of syphilis diagnosis, particularly among MSM. Urgent ophthalmic referral is required if the patient is found to have new onset visual symptoms.

  4. Did Adolf Hitler have syphilis?

    Retief, F P; Wessels, A

    2005-10-01

    The evidence that Adolf Hitler might have suffered from incapacitating syphilis is reviewed. Rumors that he acquired syphilis from a prostitute at the age of 20 years, with possible re-infection during World War I, can no longer be verified. Evidence is that he was sexually rather inactive throughout his life. Suggestions that Hitler's cardiac lesion and complaints such as transitory blindness, tremor of his left arm and leg, recurring abdominal pain and a skin lesion of the leg were of syphilitic aetiology cannot be supported. Hitler's progressive mental and physical deterioration after 1942, his growing paranoia, fits of rage, grandiosity and symptoms of possible dementia would fit in neurosyphilis. There are, however, also other explanations for his terminal syndrome, and evidence that repeated clinical examinations did not show the characteristic signs of dementia paralytica or tabes dorsalis, swings the balance of probability away from tertiary syphilis.

    2018-01-01

    Pulmonary involvement in secondary syphilis is considered a rare occurrence; however, the number of cases has increased in the 2000s. This is likely due to the increased use of computed tomography scans and molecular diagnostic testing. We report a case of an HIV-positive man with pleural chest pain and bilateral subpleural nodules on chest computed tomography. His rapid plasma reagin and Treponema pallidum hemagglutination tests were positive, and the specimen of one of the pulmonary nodules obtained by transthoracic biopsy was positive for the polA gene of Treponema pallidum. Since clinical manifestations of syphilis are highly variable, clinicians should bear in mind that pleural chest pain with bilateral subpleural nodules can be caused by pulmonary syphilis.

    2016-05-01

    Although the diversity of the clinical manifestations of syphilis is well-known, atypical presentations can also occur. Such atypical presentations are associated with a high risk of transmission as a result of diagnostic confusion and treatment delays owing to the disease's ability to mimic other common skin diseases, deviate from classic clinical presentations, and adopt unique forms. Cases of atypical syphilis have been described most frequently in patients with concomitant human immunodeficiency virus (HIV) infection. Because the incidence of syphilis has been growing over recent years -particularly in patients with HIV co-infection- dermatologists need to be familiar with the less well-known clinical presentations of this venereal disease.

    Syphilis is still a serious disease with diagnostic difficulties. In the present clinical case a patient had a routine serology screen for syphilis and HIV at a venerology clinic. He had previously presented with anogenital tumors, but the diagnosis was uncertain. A polymerase chain reaction (PCR) analysis was performed in addition to serology, and the diagnosis of syphilis in the secondary stage was confirmed. This case demonstrates how PCR technology can assist in the diagnosis of syphilis at early stages and underlines the importance of syphilis screening in homosexual men presenting with anogenital complaints.

    We present a case of ocular syphilis after a renal transplantation involving progressive vision loss without clinically identifiable ocular disease. Electroretinography showed signs of ischemia, especially in the internal retina. A serological test was positive for syphilis. Lumbar puncture revealed lymphocytic meningitis and a positive serologic test for syphilis in the cerebrospinal fluid. The patient was treated with penicillin, and had a quick vision improvement. In the case of transplant recipients, clinicians should always consider the diagnosis of ocular syphilis in cases with unexplained visual acuity decrement, as this condition may cause serious complications if not treated.

    Syphilis has continuously posed a great challenge to China. However, very little data existed regarding the cost of syphilis. Taking Guangdong Initiative for Comprehensive Control of Syphilis area as the research site, we aimed to comprehensively measure the annual economic burden of syphilis from a societal perspective. Newly diagnosed and follow-up outpatient cases were investigated by questionnaire. Reported tertiary syphilis cases and medical institutions cost were both collected. The direct economic burden was measured by the bottom-up approach, the productivity cost by the human capital method, and the intangible burden by the contingency valuation method. Three hundred five valid early syphilis cases and 13 valid tertiary syphilis cases were collected in the investigation to estimate the personal average cost. The total economic burden of syphilis was US $729,096.85 in Guangdong Initiative for Comprehensive Control of Syphilis sites in the year of 2014, with medical institutions cost accounting for 73.23% of the total. Household average direct cost of early syphilis was US $23.74. Average hospitalization cost of tertiary syphilis was US $2,749.93. Of the cost to medical institutions, screening and testing comprised the largest proportion (26%), followed by intervention and case management (22%) and operational cost (21%). Household average productivity cost of early syphilis was US $61.19. Household intangible cost of syphilis was US $15,810.54. Syphilis caused a substantial economic burden on patients, their families, and society in Guangdong. Household productivity and intangible costs both shared positive relationships with local economic levels. Strengthening the prevention and effective treatment of early syphilis could greatly help to lower the economic burden of syphilis.

    The objective of this study was to investigate if early syphilis infection affects markers of HIV infection; CD4 T cells and viral load (VL). A retrospective study was performed on 160 HIV-positive patients (111 receiving antiretroviral therapy [ART] and 49 without ART). Early syphilis diagnosis was made in HIV patients during their follow-up at the HIV/AIDS Unit at a Greek Dermatology and Venereology Unit. The patients' blood tests were available at the time of diagnosis, as well as before and 12 weeks after early syphilis diagnosis. CD4 T cell counts and VL levels were measured. It was found that syphilis infection had a negative impact on the CD4 T cell counts in both groups, with reduced CD4 T cell counts observed in 84.6% (99/111) and 79.5% (39/49) of patients receiving and not receiving ART, respectively. After treatment for syphilis, CD4 T cell counts returned to pre-treatment levels in most patients, especially those receiving ART. There was a slight and transient VL increase. Patients receiving ART had a 27% increase in VL, compared to 71.4% among patients not receiving ART. Although the VL increase was slight (41-14,000 copies/ml) in the group under treatment, 4-5% (5/111) patients did not return to pre-treatment levels. Moreover, viral mutations associated with treatment resistance were identified in these patients. Early syphilis accelerates and complicates the progression of HIV infection. Early diagnosis and treatment of syphilis may prevent infection-associated complications in most instances. Consequently, prevention of syphilis and other sexually transmitted infections is of great importance for patients infected with HIV. © The Author(s) 2016.

    Syphilis rates have increased markedly among men who have sex with men (MSM) internationally. We examined trends in syphilis testing and detection of early syphilis among MSM in Australia. Serial cross-sectional analyses on syphilis testing and diagnoses among MSM attending a national sentinel network of 46 clinics in Australia between 2007 and 2014. 359313 clinic visits were included. The proportion of MSM serologically tested for syphilis annually increased in HIV-negative (48% to 91%; Ptrend syphilis cases were detected in HIV-negative and HIV-positive MSM, respectively. Among HIV-negative MSM, the proportion of infections that were early latent increased from 27% to 44% (Ptrend syphilis correlated with increasing testing coverage (r = -0.87; P = .005) or frequency (r = -0.93; P = .001). Increases in syphilis screening were associated with increased detection of asymptomatic infectious syphilis and relative falls in secondary syphilis for both HIV-positive and HIV-negative MSM nationally, suggesting interruption of syphilis progression. © The Author 2017.

    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.

    There is a reemergence of syphilis in the Latin American and Caribbean region. There is also very little information about HIV/Syphilis co-infection and its determinants. The aim of this study is to investigate knowledge, attitudes, and practices regarding sexually transmitted infections (STIs), in particular syphilis infection and HIV/Syphilis co-infection, as well as to estimate the prevalence of syphilis among men who have sex with men (MSM) in a city with one of the highest HIV prevalence rates in Ecuador. In this study, questionnaires were administered to 291 adult MSM. Questions included knowledge about STIs and their sexual practices. Blood samples were taken from participants to estimate the prevalence of syphilis and HIV/syphilis co-infection. In this population, the prevalence of HIV/syphilis co-infection was 4.8%, while the prevalence of syphilis as mono-infection was 6.5%. Participants who had syphilis mono-infection and HIV/syphilis co-infection were older. Men who had multiple partners and those who were forced to have sex had increased odds of syphilis and HIV/syphilis co-infection. A high prevalence of syphilis and self-reported STI was observed, which warrants targeted behavioral interventions. Co-infections are a cause for concern when treating a secondary infection in a person who is immunocompromised. These data suggest that specific knowledge, attitudes, and behaviors among MSM are associated with increased odds of STIs (including HIV/syphilis co-infections) in this region of Ecuador.

    Full Text Available Objective. Tenosynovitis, inflammation of a tendon and its synovial sheath, is a rare manifestation of secondary syphilis and if diagnosed early is reversible. Background. A 52-year-old male with past medical history of untreated syphilis presented with gradual onset of swelling and pain of the right fourth metacarpophalangeal joint (MCP. He reported a history of painless penile lesions after having sexual intercourse with a new partner approximately five months ago which was treated with sulfamethoxazole/trimethoprim. An RPR done at that time came back positive with a high titer; however, patient was lost to follow-up. On examination, patient had an edematous, nonerythematous right fourth proximal interphalangeal (PIP joint. Urgent irrigation, debridement, and exploration of the right hand into the tendon sheath were performed. With his history of syphillis, an RPR was done, which was reactive with a titer of 1 : 64. A confirmatory FTA-ABS test was completed, rendering a positive result. Based on his history of untreated syphilis, dormancy followed by clinical scenario of swelling of the right fourth finger, and a high RPR titer, he was diagnosed with secondary syphilis manifesting as tenosynovitis.

    Syphilis cases have risen in many parts of China, with developed regions reporting the greatest share of cases. Since syphilis increases in these areas are likely driven by both increased screening and changes in sexual behaviours, distinguishing between these two factors is important. Examining municipal-level primary syphilis cases with spatial analysis allows a more direct understanding of changing sexual behaviours at a more policy-relevant level. In this study we examined all reported primary syphilis cases from Guangdong Province, a southern province in China, since the disease was first incorporated into the mandatory reporting system in 1995. Spatial autocorrelation statistics were used to correlate municipal-level clustering of reported primary syphilis cases and gross domestic product (GDP). A total of 52,036 primary syphilis cases were reported over the period 1995-2008, and the primary syphilis cases increased from 0.88 per 100,000 population in 1995 to 7.61 per 100,000 in 2008. The Pearl River Delta region has a disproportionate share (44.7%) of syphilis cases compared to other regions. Syphilis cases were spatially clustered (p = 0.01) and Moran's I analysis found that syphilis cases were clustered in municipalities with higher GDP (p = 0.004). Primary syphilis cases continue to increase in Guangdong Province, especially in the Pearl River Delta region. Considering the economic impact of syphilis and its tendency to spatially cluster, expanded syphilis testing in specific municipalities and further investigating the costs and benefits of syphilis screening are critical next steps.

    A panel of experts generated 8 "key questions" in the management of adult syphilis. A systematic literature review was conducted and tables of evidence were constructed to answer these important questions. Penicillin is the drug of choice to treat syphilis. Doxycycline to treat early and late latent syphilis is an acceptable alternate option if penicillin cannot be used. There is no added benefit to enhanced antimicrobial therapy when treating human immunodeficiency virus-infected persons with syphilis. If a patient misses a dose of penicillin in a course of weekly therapy for late syphilis, clinical experience suggests that an interval of 10-14 days between doses might be acceptable before restarting the sequence of injections. Pharmacologic considerations suggest that an interval of 7-9 days between doses, if feasible, may be more optimal. Missed doses are not acceptable for pregnant women. A cerebrospinal fluid examination to diagnose neurosyphilis is recommended in persons diagnosed with tertiary syphilis (eg, cardiovascular syphilis or late benign syphilis), persons with neurological signs or symptoms consistent with neurosyphilis, and asymptomatic persons whose serological titers do not decline appropriately following recommended therapy and in whom reinfection is ruled out. Infection and reinfection rates, particularly among men who have sex with men, are high. Frequent serological screening of this population appears to be the most cost-efficient intervention. The Centers for Disease Control and Prevention continues to recommend the use of the traditional rapid plasma reagin-based screening algorithm. The positive predictive value for syphilis associated with an isolated unconfirmed reactive treponemal chemiluminescence assay or enzyme immunoassay is low if the epidemiological risk and clinical probability for syphilis are low. Among pregnant women with serodiscordant serologies (positive treponemal tests and a negative nontreponemal test), the risk of

    Syphilis has plagued mankind for centuries and is currently resurgent in the Western hemisphere. While there has been a significant reduction of tertiary disease, and recognition of facilitative interactions with HIV infection, the natural history of syphilis has remained largely unchanged; thus, new strategies are required to more effectively combat this pathogen. The immunopathologic features of experimental syphilis in the rabbit; the course, stages, and pathology of human syphilis; and a comparison of human syphilis with leprosy suggest that the clinical course of syphilis and its tissue manifestations are determined by the balance between delayed type hypersensitivity (DTH) and humoral immunity to the causative agent, Treponema pallidum. A strong DTH response is associated with clearance of the infecting organisms in a well-developed chancre, whereas a cytotoxic T-cell response or strong humoral antibody response is associated with prolonged infection and progression to tertiary disease. Many of the protean symptoms/appearances of secondary and tertiary human syphilis are manifestations of immune reactions that fail to clear the organism, due to a lack of recruitment and more importantly, activation of macrophages by sensitized CD4 T-cells. The Bacillus Calmette Guerin (BCG) vaccination can enhance DTH and has been shown to produce a low, but measurable beneficial effect in the prevention of leprosy, a disease that shows a disease spectrum with characteristics in common with syphilis. In the prevention of syphilis, a potential vaccine protective against syphilis should be designed to augment the DTH response. PMID:21694502

    Full Text Available At the beginning of a new millennium, syphilis incidence has been increasing worldwide, occurring primarily among men who have sex with men (MSM. The clinical features of primary syphilis among MSM is described, a case-note review of the primary syphilis (PS patients who attended the Institute of Skin and Venereal Diseases. The diagnosis was assessed based upon the clinical features and positive syphilis serology tests. Among 25 patients with early syphilis referred during 2010, PS was diagnosed in a total of 13 cases. In all patients, unprotected oral sex was the only possible route of transmission, and two out of 13 patients had HIV co-infection. Overall, 77% of men presented with atypical penile manifestation. The VDRL test was positive with low titers. The numerous atypical clinical presentations of PS emphasize the importance of continuing education of non-experienced physicians, especially in countries with lower reported incidence of syphilis.

  18. Current status of syphilis vaccine development: need, challenges, prospects.

    Syphilis is a multistage disease caused by the invasive spirochete Treponema pallidum subsp. pallidum. Despite inexpensive and effective antibiotic therapy, syphilis remains a prevalent disease in developing countries and has re-emerged as a public health threat in developed nations. In addition to the medical burden imparted by infectious syphilis, congenital syphilis is considered the most significant infectious disease affecting fetuses and newborns worldwide, and individuals afflicted with syphilis have an enhanced risk for HIV transmission and acquisition. The global disease burden of syphilis and failure of decades of public health efforts to stem the incidence of disease highlight the need for an effective syphilis vaccine. Although challenges associated with T. pallidum research have impeded understanding of this pathogen, the existence of a relevant animal model has enabled insight into the correlates of disease protection. Complete protection against infection has been achieved in the animal model using an extended immunization regimen of γ-irradiated T. pallidum, demonstrating the importance of treponemal surface components in generation of protective immunity and the feasibility of syphilis vaccine development. Syphilis is a prime candidate for development of a successful vaccine due to the (1) research community's accumulated knowledge of immune correlates of protection; (2) existence of a relevant animal model that enables effective pre-clinical analyses; (3) universal penicillin susceptibility of T. pallidum which enhances the attractiveness of clinical vaccine trials; and (4) significant public health benefit a vaccine would have on reduction of infectious/congenital syphilis and HIV rates. Critical personnel, research and market gaps need to be addressed before the goal of a syphilis vaccine can be realized, including recruitment of additional researchers to the T. pallidum research field with a proportional increase in research funding

  19. Syphilis in the AIDS era: diagnostic dilemma and therapeutic challenge.

    Scythes, John B; Jones, Colman M

    2013-06-01

    This review argues that syphilis has been underdiagnosed and undertreated, a problem that goes back to the beginning of the Wassermann era, and indeed long before. Non-treponemal tests do not detect the larger pool of persons with latent syphilis, the immunological consequences of which have not been systematically investigated in the context of HIV infection and progression to AIDS. Recent efforts to confirm the prevalence of syphilis in high-risk patients by reverse sequence screening, i.e. using a treponemal test first, as the screening test, have revealed untreated syphilis at higher rates than expected. Further testing using PCR discovered even more previously undetected cases. We suggest that latent syphilis is a chronic active immunological condition that drives the AIDS process and cannot be managed with the older Wassermann-based algorithm, and that non-treponemal tests have failed to associate syphilis with immune suppression since this screening concept was developed in 1906. In light of the overwhelming association between a past history of syphilis and HIV seroconversion, more sensitive tools, including recombinant antigen-based immunological tests and direct detection (PCR) technology, are needed to adequately assess the role of latent syphilis in persons with HIV/AIDS. Repeating older syphilis reinoculation studies may help establish a successful animal model for AIDS, and resolve many paradoxes in HIV science.

    Full Text Available Malignant syphilis or Lues maligna, commonly reported in the pre-antibiotic era, has now seen a resurgence with the advent of human immunodeficiency virus (HIV. Immunosuppression and sexual promiscuity set the stage for this deadly association of HIV and Treponema pallidum that can manifest atypically and can prove to cause diagnostic problems. We report one such case in a 30-year-old female who responded favorably to treatment with penicillin.

    To present the findings of the Pan American Health Organization's 2014 survey on syphilis testing policies and practices in the Americas. Representatives of national/regional reference and large, lower-level laboratories from 35 member states were invited to participate. A semi-structured, electronically administered questionnaire collected data on syphilis tests, algorithms, equipment/commodities, challenges faced and basic quality assurance (QA) strategies employed (i.e. daily controls, standard operating procedures, technician training, participating in external QA programmes, on-site evaluations). The 69 participating laboratories from 30 (86%) member states included 41 (59%) national/regional reference and 28 (41%) lower-level laboratories. Common syphilis tests conducted were the rapid plasma reagin (RPR) (62% of surveyed laboratories), venereal disease research laboratory (VDRL) (54%), fluorescent treponemal antibody absorption (FTA-ABS) (41%) and Treponema pallidum haemagglutination assay (TPHA) (32%). Only three facilities reported using direct detection methods, and 28 (41% overall, 32% of lower-level facilities) used rapid tests. Most laboratories (62%) used only traditional testing algorithms (non-treponemal screening and treponemal confirmatory testing); however, 12% used only a reverse sequence algorithm (treponemal test first), and 14% employed both algorithms. Another nine (12%) laboratories conducted only one type of serologic test. Although most reference (97%) and lower-level (89%) laboratories used at least one QA strategy, only 16% reported using all five basic strategies. Commonly reported challenges were stock-outs of essential reagents or commodities (46%), limited staff training (73%) and insufficient equipment (39%). Many reference and clinical laboratories in the Americas face challenges in conducting appropriate syphilis testing and in ensuring quality of testing. © 2017 John Wiley & Sons Ltd The Pan-American Health Organization retains

    In the period from 1891 - 1910, around 2000 patients with syphilis were admitted to the Department of Dermatology, Oslo University Hospital, Rikshospitalet. The head of the department, Cæsar Boeck (1845 - 1917), believed in allowing the disease to take its natural course and withheld treatment. He made detailed notes of the diagnosis and the clinical course of the disease for all his patients. Boeck's material is unique, and forms the basis for our current knowledge about the prognosis and course of syphilis infections. In 1928, the patients were scrutinised by Boeck's successor in the Department of Dermatology, Edvin Bruusgaard (1869 - 1934), and later by Trygve Gjestland (1911 - 1993). Gjestland's doctoral thesis from 1955 has remained as «The Oslo study of untreated syphilis.» This article presents a medical historical background for the study. Bruusgaard's and Gjestland's research was important for the Tuskegee Study in the USA, and the Oslo study gave implicit support to this research project, which posterity has emphatically condemned as ethically unacceptable.

    2016-10-01

    Full Text Available The incidence of syphilis has historically been cyclical in nature, often in relation to the rise and fall of public health initiatives directed toward eradication along with social attitudes toward sexual practices. The incidence of syphilis has increased by 15% in the last 6 years in the United States, with similar increases worldwide. Herein, we present an atypical case of syphilis presenting with severe septic shock and multiple anogenital lesions in an immunocompetent host. A 22-year-old male with no significant past medical history presented with fevers, chills, sore throat, diaphoresis, and diarrhea. He was febrile, tachycardic, hypotensive, and unresponsive to fluid resuscitation requiring short-term vasopressor support. Physical exam revealed diffuse lymphadenopathy; lower extremity macular rash involving the soles of the feet; papular non-pustular lesions on the scrotum; and a 0.5 cm non-tender irregular, healing lesion on the shaft of the penis. Laboratory analysis was significant for leukocytosis and elevated creatinine. Serum screening rapid plasma reagin was positive, and further testing revealed a titer of 1:32, with confirmation via fluorescent treponemal antibody absorption test. The patient was diagnosed with secondary syphilis, which was determined to be the underlying etiology of the sepsis as all other serological evaluations were negative. He was treated with penicillin G benzathine 2.4 million units intramuscular and supportive management, with improvement of symptoms. The patient engaged in high-risk sexual behaviors, including prior unprotected sexual contact with males. New research indicates that up to one-third of patients may present with atypical cutaneous manifestations, as demonstrated by this patient. It is important for physicians to familiarize themselves with the varied clinical presentations of syphilis, which include multiple anogenital lesions and tender primary lesions in primary or secondary syphilis.

    2016-11-01

    With the recent introduction of automated treponemal tests, a new reverse syphilis algorithm has been proposed and now used by many clinical laboratories. We analyzed the impact of instituting the reverse screening syphilis algorithm in a laboratory that serves a geographic area with a moderately high prevalence of syphilis infection. Serum samples sent for syphilis testing were tested using a treponemal enzyme immunoassay (EIA) as the screening assay. EIA reactive samples were tested by rapid plasma reagin (RPR) and titered to end point if reactive. RPR nonreactive samples were analyzed by the Treponema pallidum particle agglutination test (TP-PA). Pertinent medical records were reviewed for false-reactive screens and samples with evidence of past syphilis infection. Among 10,060 patients tested, 502 (5%) were reactive on the initial EIA screen. The RPR was reactive in 150 (1.5%). TP-PA testing determined that 103 (1.0%) were falsely reactive on initial EIA screen. The reverse screening algorithm, however, identified 242 (2.4%) with evidence of latent, secondary, or past syphilis, 21 of whom had no or unknown prior treatment with antibiotics. Despite a 1.0% false-reactive rate, the reverse syphilis algorithm detected 21 patients with possible latent syphilis that may have gone undetected by traditional syphilis screening. © American Society for Clinical Pathology, 2016.

    2017-01-01

    Doxycycline is an alternative antibiotic drug for the treatment of syphilis, but data on its efficacy, especially data on its efficacy against late latent syphilis, are limited. A retrospective study was conducted to evaluate the effectiveness of doxycycline for the treatment of patients with different stages of syphilis. Patients who received doxycycline treatment between June 2011 and June 2014 were involved. The serological response to doxycycline was defined as either a negative toluidine red unheated serum test (TRUST) result or a ≥4-fold decrease in titer at 12 months following the treatment. Univariate and multivariate logistic regression analyses were performed to identify factors associated with the serological response. During the study period, a total of 163 syphilis patients were treated with doxycycline, and 118 patients completed doxycycline treatment and the 12-month follow-up. Among the 118 patients, the serological response rate at 12 months was 100.0% (7/7) in patients with primary syphilis, 96.9% (62/64) in patients with secondary syphilis, 91.3% (21/23) in patients with early latent syphilis, and 79.2% (19/24) in patients with late latent syphilis. The total serological response rates were 92.4% (109/118) for preprotocol (PP) patients and 66.9% (109/163) for all intention-to-treat (ITT) patients. In multivariate analysis, patients who serologically responded at 12 months following treatment were positively associated with a higher baseline TRUST titer and an earlier syphilis stage than nonresponders. Our study showed excellent treatment outcomes in patients with different stages of syphilis. Our data, along with those from other reports, support the usage of doxycycline as a good alternative therapeutic option in the treatment of syphilis.

  6. Economic Disparities and Syphilis Incidence in Massachusetts, 2001-2013.

    Smock, Laura; Caten, Evan; Hsu, Katherine; DeMaria, Alfred

    We used area-level indicators of poverty to describe economic disparities in the incidence rate of infectious syphilis in Massachusetts to (1) determine whether methods developed in earlier AIDS analyses in Massachusetts could be applied to syphilis and (2) characterize syphilis trends during a time of increased rates of syphilis incidence. Using census tract data and population counts from the US Census Bureau and Massachusetts data on syphilis, we analyzed the incidence rate of syphilis infection from 2001 to 2013 by the poverty level of the census tract in which people with syphilis resided, stratified by age, sex, and race/ethnicity. The syphilis incidence rate increased in all census tract groups in Massachusetts from 2001 to 2013, and disparities in incidence rates by area poverty level persisted over time. The overall incidence rate of syphilis increased 6.9-fold from 2001 to 2013 in all census tract poverty-level groupings (from 1.5 to 10.3 per 100 000 population), but the rise in rate was especially high in the poorest census tracts (from 5.6 to 31.0 per 100 000 population) and among men (from 2.2 to 19.4 per 100 000 population). The highest syphilis incidence rate was among non-Hispanic black people. The largest changes in incidence rate occurred after 2010. One region had a disproportionate increase in incidence rates and a disproportionate impact on the statewide trend. Census tract poverty analyses can inform the targeting of interventions that make progress toward reducing disparities in rates of syphilis incidence possible.

    We aimed to asses if there are differences in the clinical presentation and immune response of repeat as compared with initial syphilis. Prospective study: we prospectively recruited all patients with a new diagnosis of syphilis and tested their plasma for a range of cytochemokines and rapid plasma reagin (RPR) at baseline pretreatment and 6 months following therapy. Retrospective study: we compared RPR assay response kinetics between initial and repeat syphilis in persons attending our HIV/STI clinic from 1993 to 2016. Prospective study: a total of 91 individuals, 36 with initial syphilis and 55 with repeat syphilis, were included in the study. At baseline visit, those with initial syphilis were more likely to be symptomatic and have higher levels of interleukin-10 than repeaters. At baseline, median RPR titres were higher in the repeat than the initial infection groups. Repeaters were less likely than those with initial infections to serorevert to a negative RPR and be serofast (<4-fold RPR titre decline) at 6 months.Retrospective study: syphilis was diagnosed in 1027/43 870 individuals tested. At diagnosis, repeaters had higher RPR titres and a stepwise increase in RPR titre with number of syphilis episodes. They had a different RPR test response kinetic: they were less likely to be serofast and to serorevert than initial syphilis at 6 and 12 months. No individuals with four or more previous episodes of syphilis seroreverted. Repeat syphilis has a different clinical presentation and immunological response to initial infection. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Syphilis rates have been rapidly rising in the United States. New technologies, such as social media, might be used to anticipate and prevent the spread of disease. Because social media data collection is easy and inexpensive, integration of social media data into syphilis surveillance may be a cost-effective surveillance strategy, especially in low-resource regions. People are increasingly using social media to discuss health-related issues, such as sexual risk behaviors, allowing social media to be a potential tool for public health and medical research. This study mined Twitter data to assess whether social media could be used to predict syphilis cases in 2013 based on 2012 data. We collected 2012 and 2013 county-level primary and secondary (P&S) and early latent syphilis cases reported to the Center for Disease Control and Prevention, along with >8500 geolocated tweets in the United States that were filtered to include sexual risk-related keywords, including colloquial terms for intercourse. We assessed the relationship between syphilis-related tweets and actual case reports by county, controlling for socioeconomic indicators and prior year syphilis cases. We found a significant positive relationship between tweets and cases of P&S and early latent syphilis. This study shows that social media may be an additional tool to enhance syphilis prediction and surveillance. Copyright © 2017 Elsevier Inc. All rights reserved.

  13. Strong Country Level Correlation between Syphilis and HSV-2 Prevalence

    Science.gov (United States)

    Kenyon, Chris Richard; Tsoumanis, Achilleas

    2016-01-01

    Background. Syphilis is curable but Herpes Simplex Virus-2 (HSV-2) is not. As a result, the prevalence of syphilis but not HSV-2 may be influenced by the efficacy of national STI screening and treatment capacity. If the prevalence of syphilis and HSV-2 is found to be correlated, then this makes it more likely that something other than differential STI treatment is responsible for variations in the prevalence of both HSV-2 and syphilis. Methods. Simple linear regression was used to evaluate the relationship between national antenatal syphilis prevalence and HSV-2 prevalence in women in two time periods: 1990–1999 and 2008. Adjustments were performed for the laboratory syphilis testing algorithm used and the prevalence of circumcision. Results. The prevalence of syphilis was positively correlated with that of HSV-2 for both time periods (adjusted correlations, 20–24-year-olds: 1990–99: R 2 = 0.54, P < 0.001; 2008: R 2 = 0.41, P < 0.001 and 40–44-year-olds: 1990–99: R 2 = 0.42, P < 0.001; 2008: R 2 = 0.49, P < 0.001). Conclusion. The prevalence of syphilis and HSV-2 is positively correlated. This could be due to a common set of risk factors underpinning both STIs. PMID:27069710

    2016-11-01

    Despite the availability of inexpensive antimicrobial treatment, syphilis remains prevalent worldwide, affecting millions of individuals. Furthermore, syphilis infection is suspected of increasing both susceptibility to, and tendency to transmit, HIV. Development of a syphilis vaccine would be a potentially promising step towards control, but the value of dedicating resources to vaccine development should be evaluated in the context of the anticipated benefits. Here, we use a detailed mathematical model to explore the potential impact of rolling out a hypothetical syphilis vaccine on morbidity from both syphilis and HIV and compare it to the impact of expanded 'screen and treat' programmes using existing treatments. Our results suggest that an efficacious vaccine has the potential to sharply reduce syphilis prevalence under a wide range of scenarios, while expanded treatment interventions are likely to be substantially less effective. Our modelled interventions in our simulated study populations are expected to have little effect on HIV, and in some scenarios lead to small increases in HIV incidence, suggesting that interventions against syphilis should be accompanied with interventions against other sexually transmitted infections to prevent the possibility that lower morbidity or lower perceived risk from syphilis could lead to increases in other sexually transmitted diseases.

    BACKGROUND: Little is known about cytokine responses to syphilis infection in HIV-1-infected individuals. METHODS: We retrospectively identified patients with HIV-1 and Treponema pallidum coinfection. Plasma samples from before, during, and after coinfection were analyzed for interleukin (IL)-2, IL......-4, IL-6, IL-8, IL-10, interferon (IFN)-gamma, and tumor necrosis factor (TNF)-alpha. RESULTS: Thirty-six patients were included. IL-10 levels increased significantly in patients with primary or secondary stage syphilis from a median of 12.8 pg/mL [interquartile range (IQR), 11.0-27.8] before...... infection to 46.7 pg/mL (IQR, 28.4-78.9) at the time of diagnosis (P = 0.027) and decreased to 13.0 pg/mL (IQR, 6.2-19.4) after treatment of syphilis (P syphilis in patients with primary or secondary stage syphilis (median 3.9 pg...

    Objective: To investigate the CT features of the central nervous system in congenital syphilis infant. Methods: CT findings of central nervous system in 11 infants with clinically proved congenital syphilis were analyzed retrospectively. Results: CT findings in 10 syphilis neonates were diffuse hypodense lesions in the white matter, with subarachnoid and intra-encephalic hemorrhage in 3 and 1 cases, respectively. One 2-month-old syphilis infant case and 5 cases of follow-up after 45 days to 6 months of treatment demonstrated bilateral widened sulci and cistern with enlarged ventricles in 3 of them. Conclusion: CT findings of the central nervous system in congenital syphilis infant are similar to those of hypoxic-ischemic encephalopathy in neonates, and extra-encephalic hydrocephalus or brain hypogenesis ensues later on.

    2012-01-01

    Objectives. We examined rates of and risk factors for repeat syphilis infection among men who have sex with men (MSM) in California. Methods. We analyzed 2002 to 2006 California syphilis surveillance system data. Results. During the study period, a mean of 5.9% (range: 4.9%–7.1% per year) of MSM had a repeat primary or secondary (PS) syphilis infection within 2 years of an initial infection. There was no significant increase in the annual proportion of MSM with a repeat syphilis infection (P = .42). In a multivariable model, factors associated with repeat syphilis infection were HIV infection (odds ratio [OR] = 1.65; 95% confidence interval [CI] = 1.14, 2.37), Black race (OR = 1.84; 95% CI = 1.12, 3.04), and 10 or more recent sex partners (OR = 1.99; 95% CI = 1.12, 3.50). Conclusions. Approximately 6% of MSM in California have a repeat PS syphilis infection within 2 years of an initial infection. HIV infection, Black race, and having multiple sex partners are associated with increased odds of repeat infection. Syphilis elimination efforts should include messages about the risk for repeat infection and the importance of follow-up testing. Public health attention to individuals repeatedly infected with syphilis may help reduce local disease burdens. PMID:22095364

    To describe the recalled medical history, clinical manifestations, and treatment of yaws and syphilis by syphilis seroreactive blood donors in Kumasi, Ghana. Of the blood donors at Komfo Anokye Teaching Hospital, Kumasi, Ghana tested with the syphilis rapid diagnostic test (RDT) and later by rapid plasma reagin (RPR) test, 526 were seroreactive. Four hundred and seventy-one (89.5%) of these subjects were confirmed with the Ortho-Vitros Syphilis TP test as the gold standard and were interviewed to determine past or present clinical manifestations of yaws and syphilis. Of the 471 respondent donors, 28 (5.9%) gave a history of skin lesions and sores; four (14.3%) of these subjects, who were all male and RPR-positive, recalled a diagnosis of syphilis. All four reported having had skin lesions/bumps with slow-healing sores, but only one of them had had these symptoms before the age of 15 years. A small proportion of confirmed seroreactive donors in this sample had any recall of symptoms or treatment for yaws or syphilis. These data suggest that clinical questioning adds little further information to the current screening algorithm. The relative contribution of yaws and syphilis to frequent positive tests in endemic areas remains speculative. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Full Text Available A comparative analysis of the sensitivity and specificity of immunoblotting against other non-treponemal and treponemal reactions was carried out in 215 patients with early forms of syphilis. A high diagnostic efficiency of immunoblotting in patients with early latent syphilis was established. It was found that only in case of primary syphilis, immunoblotting is inferior to Immunofluorescence reaction; this test can be used for differential diagnosis between hidden syphilis and false positive reactions to syphilis.

    The possibilities of roentgenoendoscopic diagnostics of stomach syphilis are demonstrated by disease cases. Three forms of the stomach syphilis: tumor-like, infiltration and ulcerous ones are identified both roentgenological and endoscopic. Any infiltration process in the stomach of a young patient determined roentgenological should be reasoned as a sign of alterness relative to the syphilis. To perform endoscopic diagnosis of the stomach syphilis is easier than roentgenological one. The final syphilis diagnosis is impossible without blood test [ru

    There are minimal neurodevelopmental follow-up data for infants exposed to syphilis in utero. This is an inception cohort study of infants exposed to syphilis in utero. We reviewed women with reactive syphilis serology in pregnancy or at delivery in Edmonton (Canada), 2002 through 2010 and describe the neurodevelopmental outcomes of children with and without congenital syphilis. There were 39 births to women with reactive syphilis serology, 9 of whom had late latent syphilis (n = 4), stillbirths (n = 2) or early neonatal deaths (n = 3), leaving 30 survivors of which 11 with and 7 without congenital syphilis had neurodevelopmental assessment. Those with congenital syphilis were all born to women with inadequate syphilis treatment before delivery. Neurodevelopmental impairment was documented in 3 of 11 (27%) infants with congenital syphilis and one of 7 (14%) without congenital syphilis with speech language delays in 4 of 11 (36%) with congenital syphilis and 3 of 7 (42%) without congenital syphilis. Infants born to mothers with reactive syphilis serology during pregnancy are at high risk for neurodevelopmental impairment, whether or not they have congenital syphilis, so should all be offered neurodevelopmental assessments and early referral for services as required.

  12. Cytokine profile in patients with early latent syphilis

    Directory of Open Access Journals (Sweden)

    Zakharov S.V.

    2018-03-01

    Full Text Available The purpose of this study was to study the change in the content of the most active cytokines (interleukins 6 and 10 during the formation of the immune response in patients with latent early syphilis, as well as to study the possible relationship between the concentrations of these cytokines and the duration of the disease. In 50 patients with early latent syphilis, the concentration of interleukins 6 and 10 in serum was studied. The serum level of interleukins was studied by the enzyme immunoassay. A statistically significant increase in the concentration of interleukin 6 in the blood of patients with latent syphilis and decrease in the interleukin 10 concentration in comparison with healthy people was established. At the same time, in patients with latent syphilis with term of infection for more than 1 year, interleukin 10 has been expressed, as compared with healthy people and, especially, with patients with syphilis with a duration of infection of up to 1 year. Along with this, a lower degree of increase in the concentration of interleukin 6 in patients with latent syphilis with a duration of infection over 1 year has been established, as compared with patients with latent syphilis with a term of infection up to 1 year, against the background of its increased concentration as compared with a group of healthy individuals.

  13. Serological Tests for Acquired Syphilis in Immuno-competent Patients

    Directory of Open Access Journals (Sweden)

    Golušin Zoran

    2016-06-01

    Full Text Available Serological tests represent a valuable tool for the diagnosis and monitoring the syphilis treatment. Non-treponemal antibodies are nonspecific to detect the infection, but antibody titers are used to monitor the effects of syphilis treatment. A definitive diagnosis of syphilis is made using treponemal tests, because they detect specific antibodies to the treponemal strains or treponemal fragments, which cause syphilis. These tests may remain reactive for years, sometimes for life, regardless of the therapy outcome. Even after successful treatment, approximately 85% of patients remain positive for treponemal antibodies for the rest of their lives. However, treponemal tests cannot differentiate past infections from a current infection. Therefore, we use a combination of specific and non-specific tests, the two most frequently used diagnostic algorithms. The traditional algorithm begins with a non-treponemal assay, and if it is positive, the treponemal test is done. A positive treponemal test indicates syphilis. The reverse serology algorithm detects early, primary, and treated syphilis that may be missed with traditional screening. However, non-treponemal test is necessary to detect patients with active syphilis.

    Objective. The aim of this study was to investigate the epidemiological characteristics and adverse pregnancy outcomes of pregnant women with syphilis infection in China. Methods. Data were from China's Information System of Prevention of Mother-to-Child Transmission of Syphilis Management. Women who were registered in the system and delivered in 2013 were included in the analysis. Results. A total of 15884 pregnant women with syphilis infection delivered in China in 2013. 79.1% of infected women attended antenatal care at or before 37 gestational weeks; however, 55.4% received no treatment or initiated the treatment after 37 gestational weeks. 14.0% of women suffered serious adverse pregnancy outcomes including stillbirth/neonatal death, preterm delivery/low birth weight, or congenital syphilis in newborns. High maternal titer (≥1 : 64) and late treatment (>37 gestational weeks)/nontreatment were significantly associated with increased risk of congenital syphilis and the adjusted ORs were 1.88 (95% CI 1.27 to 2.80) and 3.70 (95% CI 2.36 to 5.80), respectively. Conclusion. Syphilis affects a great number of pregnant women in China. Large proportions of women are not detected and treated at an early pregnancy stage. Burden of adverse pregnancy outcomes is high among infected women. Comprehensive interventions still need to be strengthened to improve uptake of screening and treatment for maternal syphilis.

    2018-01-01

    Ocular syphilis has become rare in the developed world, but is a common presentation to ophthalmology departments in South Africa. We investigated the proportion of patients diagnosed with ocular syphilis who went on to receive lumbar punctures, and determined the fraction of these who had cerebrospinal fluid findings suggestive of neurosyphilis. We aimed to determine whether the use of lumbar punctures in ocular syphilis patients was beneficial in picking up cases of neurosyphilis. Retrospective study of case notes of patients admitted to two district hospitals in Durban, South Africa, with ocular syphilis over a 20-month period. A total of 31 of 68 ocular syphilis patients underwent lumbar puncture, and of these, eight (25.8%) had findings suggestive of neurosyphilis. Lumbar puncture in ocular syphilis patients should continue to be a routine part of the investigation of these patients; a large proportion of ocular syphilis patients show cerebrospinal fluid findings suggestive of neurosyphilis, are at risk of the complications of neurosyphilis, and should be managed accordingly.

    Full Text Available CLINICAL CASE A 43-year-old Romanian woman was referred with the clinical suspicion of gastric lymphoma; she had complained from two months nausea, vomiting and weight loss (7 kg; 3 esophagogastroduodenoscopic examinations had evidenced reduced distensibility of stomach body and antrum, ulcered and congestive mucosa, the histopathological examinations revealed a non specific inflammation. There was no response to therapy with omeprazolo. A computer-assisted tomoghraphy scan of the thorax and abdomen, obtained after the oral and intravenous administration of contrast material, showed diffuse thickening of the gastric wall, lymphadenopathies were seen in the retrocrural space, lesser curvature, and paraaortic region. It was performed another upper endoscopy with “deep” biopsy specimen, comprehensive of spirochetal immunohistochemistry, that was diagnostic for gastric syphilis. DISCUSSION Even though gastritis is a rare clinical manifestations of the secondary stage of syphilis, it must be considered in the differential diagnosis of erosive gastritis unresponsive to medical therapy, especially in young patients; screening tests like VDRL (routinely used until few years ago in internal medicine divisions may be useful to identify those patients needing a further diagnostic evaluation.

    Angelini, Lauretta; Guidi, Enrica; Contini, Carlo

    2009-06-01

    In this article the authors highlight the behaviour of government authorities in the nineteenth century in Italy and especially in Ferrara to implement those measures deemed necessary to stem the spread of syphilis in epidemic form through the control of prostitution. Albeit discontinuously and until 1865, corrupted and infected women in Ferrara were assisted and treated by charitable institutions (Congregation of Charity, the Congregation of the Ladies of St. Vincent and the Sisters of Charity at the complex St. Mary of Consolation) since the Ferrara public hospital (Arcispedale S. Anna) could not accept or treat infected prostitutes for economic reasons and lack of beds. Subsequently, the hospital only treated prostitutes free of charge if they bore a certificate of poverty. The other infected prostitutes were sent to the sifilicomio in Modena. The authors also study mortality from syphilis in Ferrara from 1813 to 1899 in order to detect any significant differences according to age, sex and professional status and attempt to identify the stage of the disease (primary, secondary and tertiary), according to the terminology used by the doctors of that time.

  18. Prevalence and factors associated with syphilis in a Reference Center

    Natália Carolina Rodrigues Colombo Gomes

    Full Text Available Abstract INTRODUCTION: The implementation of the rapid test (RT for syphilis increases access of vulnerable populations to early diagnosis and treatment, impacting the outcomes of infection. We aimed to assess the prevalence of and factors associated with syphilis in a Center for Testing and Counseling (CTC. METHODS: We conducted a cross-sectional study at a Reference Center for sexually transmitted disease (STD and acquired immune deficiency syndrome in Londrina, Northern Paraná State, Southern Brazil. Data regarding the 5,509 individuals who underwent RT from June 2012 to December 2014 were collected from patient records and the CTC Information System and served as the basis to check associations of syphilis cases (346 and cases without syphilis (5,163. Nine patients’ records were not found. OpenEpi was used to perform a prevalence analysis and determine odds ratios to assess the associations between sociodemographic and behavioral variables (independent variables and cases of syphilis (dependent variable. An alpha value <0.05 was considered statistically significant. RESULTS: The prevalence of syphilis was 6.3%; higher in males (7.5% than in females (4.3%, p <0.001. Syphilis was associated with an age of 25-34 years, little education, and single marital status. The main associated behavioral factors were men who have sex with men, drug users, STD patients, and those presenting with an STD in the last year. The use of alcohol, marijuana, cocaine, and crack was significantly associated with syphilis. CONCLUSIONS: Strategies for prevention and control of syphilis should be intensified, especially in populations identified as most vulnerable.

    Kaplan, Robert M

    2010-02-01

    Syphilis has changed the course of history, shaped the path of medicine and had more influence on psychiatry than any other illness. This paper, part two of a two-part series, investigates the historical, social and cultural aspects of the interaction of syphilis and psychiatry. By the end of the 19th century, social changes such as population growth, mass migration from Eastern Europe and technological developments led to a great rise in syphilis. By 1900, it was estimated that 5-20% of the population of Europe and the USA had, or would have, syphilis. By 1914, there were over 100,00 new cases and 3 million cases of syphilis in Great Britain. There was a constant interaction between syphilis, prostitution and sexual crime; it was the likely motivation for the Jack the Ripper murders, if not many in the next century. The idea of hereditary syphilis fitted perfectly into the theory of degeneration and coursed through psychiatry and caught the attention of Adolf Hitler, facilitating his antisemitic paranoia. Psychiatric progress passed to the German school, led by Kraepelin who did his first research into the symptoms and course of neurosyphilis. In 1906, Wasserman's serological test for syphilis showed that latent lesions could be present. Any doubt about the cause of syphilis was finally eliminated when Noguchi and Moore demonstrated the presence of treponema pallidum in paretic brains in 1913. German academic psychiatry defined psychiatric practice for the next century but malariotherapy, the first physical treatment in psychiatry, was announced by Julius Wagner-Juarreg in Vienna in 1917, bringing hope to the incurable and destroying the climate of therapeutic nihilism that haunted psychiatry. The first trial of malariotherapy in Australia was done by Reginald Ellery at Mont Park Hospital In 1927 in Melbourne. The discovery of penicillin was a caesura, ending malariotherapy and leading many to regard syphilis as a night-extinct illness, but this turned out to be

    Syphilis continues to be a significant public health problem among HIV-positive men who have sex with men (MSM) internationally. This study aimed to determine whether the routine inclusion of syphilis serology with every blood test performed as part of HIV monitoring increases the detection of early asymptomatic syphilis among HIV-positive MSM. We examined the effect of this intervention, implemented in January 2007, on the detection of early asymptomatic syphilis among HIV-positive MSM attending the Melbourne Sexual Health Centre, Australia, and compared this with the previous clinic policy of annual syphilis screening. In the 18 months before and after the intervention, the median number of syphilis tests performed per man per year was 1 and 2, respectively. The proportion of MSM diagnosed with early syphilis who were asymptomatic was 21% (3 of 14) and 85% (41 of 48) for the 2 respective periods (P = 0.006). The time between the midpoint since last syphilis serology and diagnosis of syphilis was a median of 107 days (range 9-362) and 45 days (range 23-325) for the 2 periods, respectively (P = 0.018). The inclusion of routine syphilis serology with every blood test performed as part of HIV monitoring in HIV-positive MSM resulted in a large increase in the proportion of men diagnosed with early asymptomatic syphilis. This simple intervention probably also decreased the duration of infectiousness, enhancing syphilis control while also reducing morbidity.

    Full Text Available Syphilis is a rare but increasing disease. Due to changing sexual habits, presentation of oral manifestations may rise. Since syphilis may mimic other oral manifestations, diagnoses can be difficult. Clinicians need to be aware that ambiguous oral manifestations may in fact be caused by oral syphilis. Here, we present a case of extended diagnostic delay highlighting the importance of consulting an expert in infectious diseases in case of obscure oral lesions not responding to standard treatment. Despite seven visits to six different medical doctors, a patient who presented with oral syphilis was continuously misdiagnosed. After 6 months of increasing complaints and deteriorating severity of disease, the patient was referred to an oral and maxillofacial surgeon where the correct diagnosis was determined and proper treatment initiated.

    Full Text Available Presently, the diagnosis of syphilis is dependent mainly on serological tests. The most widely used screening tests for syphilis are the VDRL and the rapid plasma reagin (RPR and for confirmation, the fluorescent treponemal antibody (FTA and the treponema pallidum hemagglutination (TPHA tests. The four alternative modes for diagnosis of syphilis can be a VDRL + FTA, b VDRL + TPHA, c RPR + FTA and d RPR + TPHA. Here the author reports an evaluation of cost utility of these tests in medical practice. It is shown that the cost per accurate diagnosis with VDRL + TPH is the least expensive choice. Therefore, this alternative is the best method for serological diagnosis for syphilis, based on medical laboratory economics principles

    Objective: To explore the method of radiological diagnosis of early attacking congenital syphilis. Methods: Seven cases of early attacking congenital syphilis of bone were retrospectively analyzed, diagnosed serologically, and were taken X-rays of the long bones. Results: Bone radiographs abnormalities were identified in 6 of 7 cases. Five cases suffered periotities, six cases metaphysitis, and three cases combined with diaphysitis. Seven cases had swollen soft tissue. The vertebraes, craniums and epiphysitis were not found abnormal in 7 cases. Diffusion, multiple and symmetric metaphysitis, periosteitis and osteitis were the radiological characters of congenital syphilis of bone. Conclusion: Radiography can affirm the diagnose of early attacking congenital syphilis and definite the arrange and depth. Radiographs of the extremities should be routinely taken in suspected infants. (authors)

    Full Text Available Abstract Background The last decade has seen enormous advances in HIV treatment and care, but how to implement scaled up HIV testing, prevention, and treatment in low-income areas still presents a formidable public health challenge. South China faces expanding syphilis and sexually transmitted HIV epidemics, but health systems characteristics important for scaling up syphilis and HIV testing have not been defined. Methods A purposive sample to ensure public, private, and public-private hybrid STI clinic inclusion was selected in a South China city. Eight key informant interviews were conducted with the STI clinic manager, followed by eight focus group discussions with physicians. Data collection relied on a semi-structured format that included questions in each of the following domains: 1 clinical facilities; 2 laboratory capacity with a focus on syphilis/HIV diagnosis; 3 clinic personnel; 4 physical space with a focus on locations to disclose confidential results; 5 financial support. Results Public STI clinics had free syphilis testing/treatment and laboratory facilities to perform essential syphilis and HIV tests. However, despite serving a large number of STI patients, private STI clinics lacked nontreponemal syphilis testing, HIV testing, and had fewer connections to the public health infrastructure. Formally trained assistant physicians were 2.5 times as common as physicians at STI clinics. Only one of the 8 sites had onsite voluntary counseling and testing (VCT services available. Conclusion These STI case studies reveal the potential for expanding integrated syphilis/HIV services at public STI clinics in China. More health services research is needed to guide scale-up of syphilis/HIV testing in China.

    Full Text Available ABSTRACT Introduction: In 2013, the World Health Organization (WHO reported that 1.9 million pregnant women were infected with syphilis worldwide, of which 66.5% had adverse fetal effects in cases of untreated syphilis. Congenital syphilis contributes significantly to infant mortality, accounting for 305,000 perinatal deaths worldwide annually. Aim: To estimate the prevalence of syphilis in parturients, the incidence of congenital syphilis and the vertical transmission rate. Material and methods: a cross-sectional study with data collected from 2041 parturients who had undergone treatment between 2012 and 2014 in the maternity section of the Pedro Ernesto Hospital of the State University of Rio de Janeiro, in the metropolitan area of Rio de Janeiro. The inclusion criterion was positive VDRL and treponemal test in a hospital environment. Results: the prevalence of syphilis in pregnant women was 4.1% in 2012, 3.1% in 2013 and 5% in 2014, with official reporting of 15.6%, 25.0% and 48.1%, respectively. The incidence of congenital syphilis (CS was 22/1,000 in live births (LB in 2012; 17/1,000 LB in 2013 and 44.8/1,000 LB in 2014. CS underreporting during the period was 6.7%. Vertical transmission occurred in 65.8% of infants from infected mothers. It was concluded that, in 34.6% of the CS cases, maternal VDRL titers were = 1/4. Conclusion: Results demonstrate the magnitude of the disease, fragility of the reporting system in the assessment of the actual prevalence, impact on perinatal outcomes, and they are a warning about the real situation of syphilis, which is still underestimated in the State.

    Full Text Available We present the first reported case of papulonodular secondary syphilis in an HIV-positive transgender female. Syphilis is classified into primary, secondary, latent, and tertiary stages, with secondary syphilis having notably diverse cutaneous manifestations. Our patient presented with diverse lesions throughout her body, all pathologically consistent with papulonodular secondary syphilis. Proper identification of the multiple presentations of syphilis is crucial to early diagnosis and treatment. This report seeks to broaden the scope of dermatological manifestations that arise secondary to papulonodular syphilis in HIV-positive patients.

    U.S. immigration regulations require clinical and serologic screening for syphilis for all U.S.-bound refugees 15 years of age and older. We reviewed syphilis screening results for all U.S.-bound refugees from January 1, 2009 through December 31, 2013. We calculated age-adjusted prevalence by region and nationality and assessed factors associated with syphilis seropositivity using multivariable log binomial regression models. Among 233,446 refugees, we identified 874 syphilis cases (373 cases per 100,000 refugees). The highest overall age-adjusted prevalence rates of syphilis seropositivity were observed among refugees from Africa (1340 cases per 100,000), followed by East Asia and the Pacific (397 cases per 100,000). In most regions, male sex, increasing age, and living in non-refugee camp settings were associated with syphilis seropositivity. Future analysis of test results, stage of infection, and treatment delivery overseas is warranted in order to determine the extent of transmission risk and benefits of the screening program.

    Compare syphilis investigation yield among patient groups using number needed to interview. To increase investigation efficiency. Retrospective review of North Carolina 2015 syphilis investigations, using the number of cases needed to interview (NNTI) and the total number of cases and contacts needed to interview (TNTI) to compare yield of new syphilis and human immunodeficiency virus diagnoses between patient groups. We reviewed 1646 early syphilis cases and 2181 contacts; these yielded 241 new syphilis cases (NNTI, 6.9; TNTI, 16.4) and 38 new human immunodeficiency virus cases (NNTI, 43). Interviews of women (prevalence difference [PD] = 6%, 95% confidence interval [CI], 12-16), patients 1:16 (PD = 5%, 95% CI, 1-9) yielded more new syphilis cases in our adjusted model; no other patient factors increased investigation yield. The NNTI and TNTI are useful measures of efficiency. Prioritizing early syphilis investigation by gender, rapid plasmin reagin titer, and age provides small increases in efficiency; no other factors increased efficiency.

    Full Text Available Abstract Background Recent epidemiological data show an increased trend of official estimates for syphilis infection in the general population. Many of the infected cases remain undetected leaving an underestimation of the true prevalence of syphilis in the general population, but also among subpopulations such as illicit drug users. There is limited epidemiological data published on the proportion and risk factors of syphilis infections associated with illicit drug abuse. Methods Illicit drug addicts (n = 1223 in inpatients units in Germany were screened (2000–01 for syphilis and interviewed regarding patterns of drug use and sexual behaviour. TPHA-test for initial screening and FTA-ABS-IgM test in TPHA-positive patients were used. Results In total, TPHA-tests were positive in 39 (3.3% and 7 patients (0.6% were IgM positive. The prevalence rate for syphilis in males was 1.9% and for women it was 8.5%. Female patients were 4.56 (CI 95% 2.37–8.78 times more likely to have a positive TPHA test than males. Sexual behaviours such as high number of sexual partners, sex for drugs/money, sex on the first day were associated with syphilis infection only in women. Females with frequent sex for drugs or money had 4.31 (CI 95% 2.32–8.52 times more likely a reactive TPHA test than remaining patients. Neither the sociodemographic factors nor sexual behaviour were statistically significant associated with syphilis infection among men at all. Conclusion Our data suggest the need for screening for syphilis among these illicit drug users in inpatient settings, in particular among sexual active women. This conclusion is corroborated by the finding of increasing numbers of syphilis infections in the general population. The identification of syphilis cases among drug addicts would give treatment options to these individuals and would help to reduce the spread of infection in this population, but also a spread into heterosexual populations related to

    Complexities in the diagnosis of syphilis continue to challenge clinicians. While direct tests (e.g., microscopy or PCR) are helpful in early syphilis, the mainstay of diagnosis remains serologic tests. The traditional algorithm using a nontreponemal test (NTT) followed by a treponemal test (TT) remains the standard in many parts of the world. More recently, the ability to automate the TT has led to the increasingly widespread use of reverse algorithms using treponemal enzyme immunoassays (EIAs). Rapid, point-of-care TTs are in widespread use in developing countries because of low cost, ease of use, and reasonable performance. However, none of the current diagnostic algorithms are able to distinguish current from previously treated infections. In addition, the reversal of traditional syphilis algorithms has led to uncertainty in the clinical management of patients. The interpretation of syphilis tests is further complicated by the lack of a reliable gold standard for syphilis diagnostics, and the newer tests can result in false-positive reactions similar to those seen with older tests. Little progress has been made in the area of serologic diagnostics for congenital syphilis, which requires assessment of maternal treatment and serologic response as well as clinical and laboratory investigation of the neonate for appropriate management. The diagnosis of neurosyphilis continues to require the collection of cerebrospinal fluid for a combination of NTT and TT, and, while newer treponemal EIAs look promising, more studies are needed to confirm their utility.

    Researchers have suggested that social media and online search data might be used to monitor and predict syphilis and other sexually transmitted diseases. Because people at risk for syphilis might seek sexual health and risk-related information on the internet, we investigated associations between internet state-level search query data (e.g., Google Trends) and reported weekly syphilis cases. We obtained weekly counts of reported primary and secondary syphilis for 50 states from 2012 to 2014 from the US Centers for Disease Control and Prevention. We collected weekly internet search query data regarding 25 risk-related keywords from 2012 to 2014 for 50 states using Google Trends. We joined 155 weeks of Google Trends data with 1-week lag to weekly syphilis data for a total of 7750 data points. Using the least absolute shrinkage and selection operator, we trained three linear mixed models on the first 10 weeks of each year. We validated models for 2012 and 2014 for the following 52 weeks and the 2014 model for the following 42 weeks. The models, consisting of different sets of keyword predictors for each year, accurately predicted 144 weeks of primary and secondary syphilis counts for each state, with an overall average R of 0.9 and overall average root mean squared error of 4.9. We used Google Trends search data from the prior week to predict cases of syphilis in the following weeks for each state. Further research could explore how search data could be integrated into public health monitoring systems.

    2016-01-01

    Background How can we explain the uneven decline of syphilis around the world following the introduction of penicillin? In this paper we use antenatal syphilis prevalence (ASP) to investigate how syphilis prevalence varied worldwide in the past century, and what risk factors correlate with this variance. Methods 1) A systematic review using PubMed and Google Scholar was conducted to identify countries with published data relating to ASP estimates from before 1952 until the present. Eleven countries were identified (Canada, Denmark, Finland, India, Japan, Norway, Singapore, South Africa, United States of America (USA), United Kingdom (UK) and Zimbabwe). The ASP epidemic curve for each population was depicted graphically. In South Africa and the USA, results are reported separately for the black and white populations. 2) National antenatal syphilis prevalence estimates for 1990 to 1999 and 2008 were taken from an Institute for Health Metrics and Evaluation database on the prevalence of syphilis in low risk populations compiled for the Global Burden of Diseases study and from a recent review paper respectively. National ASPs were depicted graphically and regional median ASPs were calculated for both time periods. 3) Linear regression was used to test for an association between ASP in 1990–1999 and 2008 and four risk factors (efficacy of syphilis screening/treatment, health expenditure, GDP per capita and circumcision prevalence). WHO world regions were included as potential explanatory variables. Results In most populations, ASP dropped to under 1% before 1960. In Zimbabwe and black South Africans, ASP was high in the pre-penicillin period, dropped in the post-penicillin period, but then plateaued at around 6% until the end of the 20th century when ASP dropped to just above 1%. In black Americans, ASP declined in the post penicillin period, but plateaued at 3–5% thereafter. ASP was statistically significantly higher in sub-Saharan Africa in 1990–1999 and 2008

    Syphilis remains an important and preventable cause of stillbirth and neonatal mortality. About 1 million women with active syphilis become pregnant each year. Without treatment, 25% of them will deliver a stillborn baby and 33% a low birth weight baby with an increased chance of dying in the first month of life. Adverse pregnancy outcomes due to syphilis can be prevented by screening pregnant women, and treating those who test positive with a single dose of penicillin before 28 weeks' gestation. Areas covered: This manuscript covers the impact of syphilis on pregnancy outcome, the diagnosis of syphilis, with a special focus on point of care (POC) tests, and challenges to the introduction of POC tests, and their potential impact on the control and prevention of syphilis in resource limited settings. Expert commentary: POC tests for syphilis are available which meet the ASSURED criteria, and could make syphilis screening accessible to all women anywhere in the world who attend an antenatal clinic. High quality dual POC tests for HIV and syphilis could ensure that well-funded programmes for the prevention of mother to child transmission of HIV can contribute towards increased coverage of antenatal syphilis screening, and prevent more than 300,000 adverse pregnancy outcomes due to syphilis annually. Alongside investment to increase availability of syphilis POC tests, operational research is needed to understand how best to improve screening of pregnant women and to translate test availability into improved pregnancy outcomes.

    Awareness of the increased prevalence of syphilis is essential for early diagnosis and treatment, and to prevent the spread of the disease. Although serological studies are the primary tool used to confirm the diagnosis of secondary syphilis, biopsy of unsuspected oral lesions is not uncommon in the routine oral pathology laboratory. In these cases, histopathological characteristics are likely to indicate the possibility of syphilis, and an immunohistochemical reaction can confirm it. The aim of the present study was to highlight the histological features and test the efficacy of immunohistochemistry in the detection of Treponema pallidum in oral lesions biopsied with the assumption of a non-syphilitic disease. Thirty-nine tissue samples from patients for whom the possibility of syphilis was suggested on the basis of histopathological findings, were retrieved from the surgical oral pathology service files and submitted to immunohistochemical staining for T. pallidum. The study was approved by the institutional ethics committee. Eighteen of the tissue samples were positive for T. pallidum. Following this, the contributing clinicians were contacted to check whether they had asked for serological examinations when the diagnostic report was received; for all 18 positive cases, the clinicians confirmed that the patients had tested positive at that time. This study shows the importance of clinical-pathological correlation and the value of immunohistochemistry in the diagnosis of unsuspected syphilis.

    The aim of this study was to examine trends in infectious syphilis epidemiology among women in Winnipeg, Canada. A descriptive study of syphilis among Winnipeg residents between 2003 and 30 June 2015 was undertaken. Adjusted rate ratios (ARR) and 95% confidence intervals (95%CI) from Poisson regression analyses are reported. Characteristics of men and women were compared using logistic regression, with adjusted odds ratios (AOR) reported. Between 2014 and 2015, the rate of syphilis was 1.7/100,000, representing a five-fold increase since 2006-2013. All cases have been heterosexual, 90% 20-39 years of age, and 59% living in Winnipeg's inner core. Approximately 24% were pregnant at diagnosis; no cases of congenital syphilis have been reported. Compared to men, women were more likely to report alcohol use (AOR: 3.8, 95% CI: 1.2-11.9) and co-infection with chlamydia (AOR: 5.0, 95% CI: 1.1-22.9). In conclusion, the rates of infectious syphilis are increasing among women. Prenatal screening and education for inner-core women and the health care providers serving them should be prioritized.

    These guidelines are an update for 2015 of the 2008 UK guidelines for the management of syphilis. The writing group have piloted the new BASHH guideline methodology, notably using the GRADE system for assessing evidence and making recommendations. We have made significant changes to the recommendations for screening infants born to mothers with positive syphilis serology and to facilitate accurate and timely communication between the teams caring for mother and baby we have developed a birth plan. Procaine penicillin is now an alternative, not preferred treatment, for all stages of syphilis except neurosyphilis, but the length of treatment for this is shortened. Other changes are summarised at the start of the guideline. © The Author(s) 2016.

    Leucoderma syphiliticum (LS), originally described as syphilide pigmentaire, encompasses a spectrum of dyschromic lesions that emerge during the course of secondary syphilis. Very few case reports are available in modern biomedical databases. We present the case of a 57-year-old HIV-infected male patient who presented with several round to oval, non-scaling, slightly raised and well-demarcated hypochromic lesions scattered over the trunk, abdomen, dorsum, and arms. Prior non-treponemal tests were negative for syphilis, but novel studies yielded positive results at high titers. Skin lesions slowly regressed and the hypochromic areas repigmented a few weeks after benzathine penicillin G treatment. This is the first report of LS in an HIV-infected patient. A review of modern and ancient literature was performed. The present case report emphasizes the need for clinicians to have a heightened awareness of the varied and unusual clinical phenotypes of syphilis.

    To estimate the rates of syphilis infection in inner-city patients managed by prehospital providers, a convenience sampling of prehospital patients who had intravenous lines initiated was screened for syphilis over a nine-month study period from February 1992 through October 1992. In a university-affiliated inner-city emergency department served by a city ambulance company, patients 18 years of age or older transported via ambulance who had had intravenous lines initiated at the scene or en route had a Venereal Disease Research Laboratory (VDRL) and microhemagglutination-Treponema pallidum (MHA-TP) drawn and performed by the state laboratory as a routine serological test. If the results were reactive with no previous history of syphilis recorded in the state registry, the state health department and/or one of the authors of this study contacted the patient for follow-up treatment. Age, race, sex, and diagnostic category (medical, surgical/obstetric, or neuropsychiatric) were recorded. Results were checked with the state syphilis registry. Latent syphilis was defined as a reactive VDRL and MHA-TP with no prior history of infection or record of infection in the state syphilis registry. Chi-squared test was used in statistical analysis for comparisons among ages, races, and sexes, with P > .05 considered significant. Three hundred two subjects 18 years of age and older consenting to a screening VDRL and MHA-TP had serum drawn. Two hundred seventy-nine patients were enrolled in the study after 23 patients were excluded because of improper data collection or insufficient serum collection. There were 174 men (63%) and 105 women (37%), with 73 white (26%) and 199 African-Americans (71%).(ABSTRACT TRUNCATED AT 250 WORDS)

    Congenital syphilis (CS) is a major global public health problem. Buenaventura, a socioeconomically deprived municipality in the Colombian Pacific Coast, accounts for 6.6% of all CS cases in Colombia. To begin to understand the main reasons for the high rates of the disease in Buenaventura, we conducted a retrospective electronic health record analysis of all infants admitted with CS during the first 7 months of 2011 to the Hospital Departamental de Buenaventura, the city's main birthing hospital. The diagnosis of gestational syphilis and CS was based on a predefined Colombian public health service algorithm. Clinical, laboratory, and sociodemographic parameters for all infants studied, including maternal access to prenatal care, syphilis serologic diagnosis, and adequacy of penicillin treatment, were abstracted and analyzed. A total of 89 infants met the case definition for CS. Most mothers (80%) were affiliated with government-regulated or private health care insurance plans. While 64 (70%) of 92 attended at least 1 antenatal care visit and 59 of these 64 (84%) were screened for syphilis, only 5 (8%) of 59 received appropriate antibiotic therapy. Although most infants were asymptomatic at birth, prematurity (15/82) was common. Two infants died in the neonatal period, and 5 pregnancies ended in stillbirth. Our findings confirm that Buenaventura has a very high incidence of CS and demonstrate that existing antenatal care gestational syphilis programs are flawed. Prevention strategies should emphasize enhanced early syphilis screening in pregnancy, preferably through the implementation of point-of-care testing in the community and same-day treatment with at least 1 dose of penicillin.

    Syphilis is a rare disease in the rectum. It is difficult to diagnose because the characteristics of the rectal syphilis rectal lesion are highly varied. The endoscopic findings of rectal syphilis are proctitis, ulcers, and masses. If rectal syphilis is suspected to be the cause for rectal lesions, it is important for physicians to consider the sexual history and sexual orientation of the patient. We report a case of incidental rectal syphilis in a 41-year-old man diagnosed during a regular medical check-up.

    Syphilis is a fascinating and perplexing infection, with protean clinical manifestations and both diagnostic and management ambiguities. Treponema pallidum subsp. pallidum, the agent of syphilis, is challenging to study in part because it cannot be cultured or genetically manipulated. Here, we review recent progress in the application of modern molecular techniques to understanding the biological basis of this multistage disease and to the development of new tools for diagnosis, for predicting efficacy of treatment with alternative antibiotics, and for studying the transmission of infection through population networks.

    Syphilis can be transmitted by pregnant women to their children and is a public health problem in Africa. A cross-sectional survey was conducted in 24 antenatal clinics from 2002 to 2003 and increased to 30 sites from 2005 to 2011. Participants were tested for syphilis and HIV. Multi-variate logistic regression was performed to identify risks associated with syphilis and its co-infection with HIV. Results showed that syphilis decreased from 3.8% in 2002 to 2.0% in 2011. Syphilis in the HIV-infected participants increased from 6.0% in 2002 to 10.8% in 2011, but decreased from 3.7% to 1.7% in the HIV-negative participants. In 2011, syphilis in urban participants was 2.7% and 1.4% in rural ones. HIV-infected participants screened positive for syphilis more frequently in both rural (aOR = 3.64 [95% CI: 1.56%-8.51%]) and urban areas (aOR = 7.26 [95% CI: 5.04%-10.46%]). Older participants (25-49 years) residing in urban areas (aOR = 0.43[95% CI: 0.32%-0.58%]) and women with secondary or high education (aOR = 0.35[95% CI: 0.20%-0.62%]) were less likely to screen positive for syphilis. HIV-syphilis co-infection was more likely in women residing in urban areas (aOR = 8.32[95% CI: 3.54%-19.56%]), but less likely in women with secondary/high education (aOR = 0.11[95% CI: 0.01%-0.77%]). In conclusion, syphilis increased in HIV-positive pregnant women, but decreased in HIV-negative women. Positive HIV status and young age were associated risks for syphilis. HIV-syphilis co-infection was associated with a lower level of education and urban residence.

    Early diagnosis of syphilis and timely treatment can effectively reduce ongoing syphilis transmission and morbidity. We examined the factors associated with the early diagnosis of syphilis to inform syphilis screening strategic planning. In an observational study, we analyzed reported syphilis cases in Guangdong Province, China (from 2014 to mid-2015) accessed from the national case-based surveillance system. We categorized primary and secondary syphilis cases as early diagnosis and categorized latent and tertiary syphilis as delayed diagnosis. Univariate analyses and multivariable logistic regressions were performed to identify the factors associated with early diagnosis. We also examined the factors associated with early diagnosis at the individual and city levels in multilevel logistic regression models with cases nested by city (n = 21), adjusted for age at diagnosis and gender. Among 83,944 diagnosed syphilis cases, 22% were early diagnoses. The city-level early diagnosis rate ranged from 7 to 46%, consistent with substantial geographic variation as shown in the multilevel model. Early diagnosis was associated with cases presenting to specialist clinics for screening, being male and attaining higher education level. Cases received syphilis testing in institutions and hospitals, and diagnosed in hospitals were less likely to be in early diagnosis. At the city-level, cases living in a city equipped with more hospitals per capita were less likely to be early diagnosis. To enhance early diagnosis of syphilis, city-specific syphilis screening strategies with a mix of passive and client/provider-initiated testing might be a useful approach.

    The infection rate of syphilis in China has increased dramatically in recent decades, becoming a serious public health concern. Early prediction of syphilis is therefore of great importance for heath planning and management. In this paper, we analyzed surveillance time series data for primary, secondary, tertiary, congenital and latent syphilis in mainland China from 2005 to 2012. Seasonality and long-term trend were explored with decomposition methods. Autoregressive integrated moving average (ARIMA) was used to fit a univariate time series model of syphilis incidence. A separate multi-variable time series for each syphilis type was also tested using an autoregressive integrated moving average model with exogenous variables (ARIMAX). The syphilis incidence rates have increased three-fold from 2005 to 2012. All syphilis time series showed strong seasonality and increasing long-term trend. Both ARIMA and ARIMAX models fitted and estimated syphilis incidence well. All univariate time series showed highest goodness-of-fit results with the ARIMA(0,0,1)×(0,1,1) model. Time series analysis was an effective tool for modelling the historical and future incidence of syphilis in China. The ARIMAX model showed superior performance than the ARIMA model for the modelling of syphilis incidence. Time series correlations existed between the models for primary, secondary, tertiary, congenital and latent syphilis.

    Full Text Available Abstract Background Globally syphilis is an important yet preventable cause of stillbirth, neonatal mortality and morbidity. Objectives This review sought to estimate the effect of detection and treatment of active syphilis in pregnancy with at least 2.4MU benzathine penicillin (or equivalent on syphilis-related stillbirths and neonatal mortality. Methods We conducted a systematic literature review of multiple databases to identify relevant studies. Data were abstracted into standardised tables and the quality of evidence was assessed using adapted GRADE criteria. Where appropriate, meta-analyses were undertaken. Results Moderate quality evidence (3 studies supports a reduction in the incidence of clinical congenital syphilis of 97% (95% c.i 93 – 98% with detection and treatment of women with active syphilis in pregnancy with at least 2.4MU penicillin. The results of meta-analyses suggest that treatment with penicillin is associated with an 82% reduction in stillbirth (95% c.i. 67 – 90% (8 studies, a 64% reduction in preterm delivery (95% c.i. 53 – 73% (7 studies and an 80% reduction in neonatal deaths (95% c.i. 68 – 87% (5 studies. Although these effect estimates were large and remarkably consistent across studies, few of the studies adjusted for potential confounding factors and thus the overall quality of the evidence was considered low. However, given these large observed effects and a clear biological mechanism for effectiveness the GRADE recommendation is strong. Conclusion Detection and appropriate, timely penicillin treatment is a highly effective intervention to reduce adverse syphilis-related pregnancy outcomes. More research is required to identify the most cost-effective strategies for achieving maximum coverage of screening for all pregnant women, and access to treatment if required.

    Laboratory diagnosis of syphilis is usually accomplished by serology. There are currently a large number of different commercial treponemal tests available that vary in format, sensitivity and specificity. To evaluate the ID-PaGIA Syphilis Antibody Test as an alternative to other specific treponemal tests for primary screening or confirmation of diagnosis. Serum samples from healthy adults (n = 100) were used for detection of specificity of ID-PaGIA. To evaluate sensitivity of ID-PaGIA serum samples (n = 101) from patients with confirmed or suspected syphilis were tested for syphilis antibodies with FTA-Abs IgM, ID-PaGIA, ELISA IgM and TPHA tests. No false-positive results were found with ID-PaGIA. Sensitivity of various treponemal tests was the following: FTA-Abs IgM: 95.5%, ID-PaGIA and ELISA IgM: 94%, and TPHA 75%. The positive and negative predictive values of ID-PaGIA were 100 and 89.5%, respectively. Compared with other treponemal tests ID-PaGIA has excellent sensitivity and specificity.

    We describe a series of cases of syphilis with atypical extracutaneous clinical presentation diagnosed in HIV-infected patients. Retrospective observational study. All cases of syphilis diagnosed in HIV-infected patients during the period between June 2013 and June 2016 in a tertiary hospital of the Barcelona metropolitan area were analysed. A total of 71 cases of syphilis were diagnosed, 32 of them presenting with clinical signs or symptoms. Seven of these cases (9.8% of the total and 21.8% of the symptomatic cases) had atypical presentations with extracutaneous involvement: ocular (4), gastric (1), multiple hepatic abscesses (1) and generalised adenopathies (1). Patients were treated with intramuscular or intravenous penicillin and the clinical and serological evolution was good in all of them. Extracutaneous atypical clinical presentations were observed in 21.8% of symptomatic cases of syphilis in HIV+ patients with ocular involvement being the most freqent.

    1998-01-01

    Purpose: The participation of minorities in clinical studies is the subject of much discussion and has even become the subject of Federal law. The project known as the Tuskegee Syphilis Study and officially titled 'The Tuskegee Study of Untreated Syphilis in the Negro Male', is one of the great debacles of American medicine and a national shame. Despite the fact that its existence is well known, many do not know the historical facts of the study nor the context of the study. My purpose here is to recount the facts of the study and its historical context. Methods: The history recounted here is taken from documents gathered during a U.S. Senate investigation of the study, original papers located in National Library of Medicine, and books about the trial. Results: The trial began in 1931 as a survey of the natural history of untreated tertiary syphilis in Black men. This study enrolled 399 men with syphilis and 201 uninfected men to serve as controls. All were at least 25 years old at enrollment. The men were told they were in a study, but never educated about the implications. Later, men were not informed that there was a treatment for effective treatment for their disease - a treatment that was being withheld from them. This trial continued till 1972. Conclusion: Many of the issues that led to the study and caused it to continue for 40 years still exist. The lessons of the Public Health Study of Untreated Syphilis in the Untreated Negro include the dangers of paternalism, arrogance, blind loyalty, and misuse of science.

    Full Text Available ABSTRACT OBJECTIVE To determine the sociodemographic, behavioral, and health care factors related to the occurrence of syphilis in women treated at public maternity hospitals. METHODS This is a case-control study (239 cases and 322 controls with women admitted to seven maternity hospitals in the municipality of Recife, Brazil, from July 2013 to July 2014. Eligible women were recruited after the result of the VDRL (Venereal Disease Research Laboratory under any titration. The selection of cases and controls was based on the result of the serology for syphilis using ELISA (enzyme-linked immunosorbent assay. The independent variables were grouped into: sociodemographic, behavioral, clinical and obstetric history, and health care in prenatal care and maternity hospital. Information was obtained by interview, during hospitalization, with the application of a questionnaire. Odds ratios and 95% confidence intervals were estimated using logistic regression to identify the predicting factors of the variable to be explained.

    ABSTRACT OBJECTIVE To determine the sociodemographic, behavioral, and health care factors related to the occurrence of syphilis in women treated at public maternity hospitals. METHODS This is a case-control study (239 cases and 322 controls) with women admitted to seven maternity hospitals in the municipality of Recife, Brazil, from July 2013 to July 2014. Eligible women were recruited after the result of the VDRL (Venereal Disease Research Laboratory) under any titration. The selection of cases and controls was based on the result of the serology for syphilis using ELISA (enzyme-linked immunosorbent assay). The independent variables were grouped into: sociodemographic, behavioral, clinical and obstetric history, and health care in prenatal care and maternity hospital. Information was obtained by interview, during hospitalization, with the application of a questionnaire. Odds ratios and 95% confidence intervals were estimated using logistic regression to identify the predicting factors of the variable to be explained. RESULTS The logistic regression analysis identified as determinant factors for gestational syphilis: education level of incomplete basic education or illiterate (OR = 2.02), lack of access to telephone (OR = 2.4), catholic religion (OR = 1.70 ), four or more pregnancies (OR = 2.2), three or more sexual partners in the last year (OR = 3.1), use of illicit drugs before the age of 18 (OR = 3.0), and use of illicit drugs by the current partner (OR = 1.7). Only one to three prenatal appointments (OR = 3.5) and a previous history of sexually transmitted infection (OR = 9.7) were also identified as determinant factors. CONCLUSIONS Sociodemographic, behavioral, and health care factors are associated with the occurrence of syphilis in women and should be taken into account in the elaboration of universal strategies aimed at the prevention and control of syphilis, but with a focus on situations of greater vulnerability.

    Full Text Available Goal. To conduct a comparative assessment of the results of regulated serological tests obtained as a result of blood tests in patients suffering from latent syphilis. Materials and methods. The authors examined 187 patient medical records with newly diagnosed latent syphilis in FGBU GNTsDK (State Research Center for Dermatology, Venereology and Cosmetology, Health Ministry of the Russian Federation, in 2006-2015. The results of patient blood tests were analyzed with the use of non-treponemal (microprecipitation test/RPR and treponemal (passive hemagglutination test, immune-enzyme assay (IgA, IgM, IgG, IFabs, immunofluorescence test and Treponema pallidum immobilization test serology tests. Results. According to the results of blood tests of latent syphilis patients, the largest number of positive results was obtained as a result of treponemal serology tests such as immune-enzyme assay (100%, passive hemagglutination test (100% and IFabs (100%. The greatest number of negative results was observed in non-treponemal (microprecipitation test/RPR serology tests: in 136 (72.7% patients; evidently positive results (4+ test results were obtained in 8 (4.3% patients only. According to the results of a comparative analysis of blood tests in patients suffering from latent syphilis obtained with the use of treponemal serology tests, the greatest number of evidently positive results (4+ was noted for the passive hemagglutination test (67.9%. Negative treponemal test results were obtained with the use of the immunofluorescence test and Treponema pallidum immobilization test (21.9% and 11.8% of cases, respectively. Moreover, weakly positive results prevailed for the immunofluorescence test: in 65 (34.7% patients. Conclusion. These data confirm that the following treponemal tests belong to the most reliable ones for revealing patients suffering from latent syphilis: immune-enzyme assay, passive hemagglutination test and IFabs.

    Syphilis is a health problem of increasing incidence in recent years that may have severe complications if not diagnosed and treated at an early stage. There are many diagnostic tests available for syphilis, but there is no gold standard, and diagnosis therefore usually relies upon a combination of tests. In this multicenter study, we evaluated the treponemal Elecsys syphilis assay for use in the diagnosis of syphilis in routine samples, i.e., when syphilis is suspected or during antenatal or blood donation screening. The sensitivity and specificity of the Elecsys syphilis assay were compared head to head with those of other treponemal assays used in routine clinical practice and were assessed in potentially cross-reactive samples from patients with Epstein-Barr virus, HIV, and Lyme disease. In a total of 8,063 syphilis-negative samples collected from routine diagnostic requests and blood donations, the Elecsys syphilis assay had a specificity of 99.88%. In 928 samples previously identified as syphilis positive, the sensitivity was 99.57 to 100% (the result is presented as a range depending on whether four initially indeterminate samples are included in the assessment). The specificity of the Elecsys syphilis assay in patients with other infections was 100%; no false-positive samples were identified. Copyright © 2015, American Society for Microbiology.

    Full Text Available How can we explain the uneven decline of syphilis around the world following the introduction of penicillin? In this paper we use antenatal syphilis prevalence (ASP to investigate how syphilis prevalence varied worldwide in the past century, and what risk factors correlate with this variance.1 A systematic review using PubMed and Google Scholar was conducted to identify countries with published data relating to ASP estimates from before 1952 until the present. Eleven countries were identified (Canada, Denmark, Finland, India, Japan, Norway, Singapore, South Africa, United States of America (USA, United Kingdom (UK and Zimbabwe. The ASP epidemic curve for each population was depicted graphically. In South Africa and the USA, results are reported separately for the black and white populations. 2 National antenatal syphilis prevalence estimates for 1990 to 1999 and 2008 were taken from an Institute for Health Metrics and Evaluation database on the prevalence of syphilis in low risk populations compiled for the Global Burden of Diseases study and from a recent review paper respectively. National ASPs were depicted graphically and regional median ASPs were calculated for both time periods. 3 Linear regression was used to test for an association between ASP in 1990-1999 and 2008 and four risk factors (efficacy of syphilis screening/treatment, health expenditure, GDP per capita and circumcision prevalence. WHO world regions were included as potential explanatory variables.In most populations, ASP dropped to under 1% before 1960. In Zimbabwe and black South Africans, ASP was high in the pre-penicillin period, dropped in the post-penicillin period, but then plateaued at around 6% until the end of the 20th century when ASP dropped to just above 1%. In black Americans, ASP declined in the post penicillin period, but plateaued at 3-5% thereafter. ASP was statistically significantly higher in sub-Saharan Africa in 1990-1999 and 2008 than in the other world

    Despite recent technological advances, the diagnosis of syphilis remains a challenging enterprise. Actually, most high-volume laboratories have adopted the "reverse algorithm" due several factors, including the potential to automate testing. Recently, immunoassays processed on random-access systems have been proposed as screening tests. The purpose of this study was to evaluate diagnostic performances of BioPlex 2200 Syphilis IgG and BioPlex 2200 Syphilis IgM, tests based on Multiplex Flow technology, in comparison with the performance of Architect Syphilis TP, a chemiluminescent immunoassay for the detection of IgG and/or IgM anti-Treponema pallidum antibodies. A retrospective study was performed with a panel of 100 blood donor sera, a panel of 350 clinical and laboratory-characterized syphilitic sera, and 170 samples obtained from subjects with potentially interfering conditions. Moreover, 200 unselected samples submitted to the Microbiology Laboratory of St. Orsola Hospital in Bologna for routine screening for syphilis were evaluated. As confirmatory tests, T. pallidum hemagglutination and Western blot assays were used. Considering the IgG Western blot (WB) assay to be the gold standard method, BioPlex 2200 Syphilis IgG specificity was far higher than Architect Syphilis TP specificity (89.7% versus 78.4%, respectively), whereas the sensitivity was 100% for both automated methods. Compared to the IgM WB assay, BioPlex 2200 Syphilis IgM performed with a specificity of 94.9%, whereas the sensitivity was 84.8%. Considering the excellent ease of use and automation, the high sample throughput and its valuable analytical performances, BioPlex Syphilis 2200 IgG could represent a suitable choice for high-volume laboratories. BioPlex Syphilis 2200 IgM could be considered a good addition to IgG testing for uncovering active infections.

    2016-11-01

    Syphilis and human immunodeficiency virus (HIV) coinfection disproportionately affects men who have sex with men (MSM), and the rate of coinfection has been increasing over the last decade. HIV and syphilis coinfection is particularly challenging because the infections interact synergistically thereby increasing the risk of acquisition and transmission as well as accelerating disease progression. Areas covered: This paper reviews and summarizes the epidemiology, pathogenesis, diagnosis, clinical management and prevention of HIV and syphilis coinfection among MSM. Expert commentary: Research does not support a different syphilis treatment for coinfected individuals; however, coinfection may warrant a recommendation for antiretroviral therapy. In order to reverse the epidemic of syphilis and HIV coinfection, there needs to be greater awareness, improved cultural sensitivity among health care providers, improved access to preventative services and increased screening for syphilis and HIV.

    The Treponemal test algorithm for syphilis screening is widely used. A diagnostic challenge between identifying early syphilis versus a false positive signal occurs in cases where the treponemal enzyme immunoassay (EIA) is reactive and confirmatory T. pallidum particle agglutination assay is negative. We investigated the diagnostic outcome of isolated reactive EIA in patients attending a sexual health clinic. Results of syphilis serology tests carried out at Birmingham Whittall Street Clinic between August 10, 2010, and November 31, 2014, were reviewed. Cases with isolated EIA were routinely invited for repeat syphilis serology. Outcomes of patients with isolated EIA were reviewed and the proportion with confirmed positive syphilis serology on their repeat test identified. The number of isolated EIA cases needed to retest to identify 1 case of early syphilis was calculated. A total of 121,724 syphilis screening tests were performed. Among the 1561 individual patients with reactive EIA sera, 316 (20% of total reactive tests) had isolated reactive EIA. Repeat syphilis serology results of 163 patients were reviewed; 106 patients remained with isolated reactive EIA, 50 had negative EIA test and 7 (4.3%) had confirmed reactive EIA. Of the 7 patients, 2 had evidence of early syphilis infection. The number of isolated EIA needed to retest to identify 1 case of early syphilis was 81.5 (95% confidence interval, 22.9-671.4). Routine recall of patients with isolated EIA sera is not warranted. Risk of acquisition or presence of early syphilis should be assessed independently and irrespective of a negative syphilis screening test or isolated EIA.

    Treponema pallidum infections can have severe complications if not diagnosed and treated at an early stage. Screening and diagnosis of syphilis require assays with high specificity and sensitivity. The Elecsys Syphilis assay is an automated treponemal immunoassay for the detection of antibodies against T. pallidum The performance of this assay was investigated previously in a multicenter study. The current study expands on that evaluation in a variety of diagnostic settings and patient populations, at seven independent laboratories. The samples included routine diagnostic samples, blood donation samples, samples from patients with confirmed HIV infections, samples from living organ or bone marrow donors, and banked samples, including samples previously confirmed as syphilis positive. This study also investigated the seroconversion sensitivity of the assay. With a total of 1,965 syphilis-negative routine diagnostic samples and 5,792 syphilis-negative samples collected from blood donations, the Elecsys Syphilis assay had specificity values of 99.85% and 99.86%, respectively. With 333 samples previously identified as syphilis positive, the sensitivity was 100% regardless of disease stage. The assay also showed 100% sensitivity and specificity with samples from 69 patients coinfected with HIV. The Elecsys Syphilis assay detected infection in the same bleed or earlier, compared with comparator assays, in a set of sequential samples from a patient with primary syphilis. In archived serial blood samples collected from 14 patients with direct diagnoses of primary syphilis, the Elecsys Syphilis assay detected T. pallidum antibodies for 3 patients for whom antibodies were not detected with the Architect Syphilis TP assay, indicating a trend for earlier detection of infection, which may have the potential to shorten the time between infection and reactive screening test results.

    Full Text Available Abstract Background Syphilis is a growing public health problem among men who have sex with men (MSM globally. Rapid and accurate detection of syphilis is vital to ensure patients and their contacts receive timely treatment and reduce ongoing transmission. Methods We evaluated a PCR assay for the diagnosis of Treponema pallidum using swabs of suspected early syphilis lesions in longitudinally assessed MSM. Results We tested 260 MSM for T pallidum by PCR on 288 occasions: 77 (26.7% had early syphilis that was serologically confirmed at baseline or within six weeks, and 211 (73.3% remained seronegative for syphilis. Of 55 men with primary syphilis, 49 were PCR positive, giving a sensitivity of 89.1% (95% CI: 77.8%-95.9% and a specificity of 99.1% (95% CI: 96.5%-99.9%. Of 22 men with secondary syphilis, 11 were PCR positive, giving a sensitivity of 50% (95% CI: 28.2%-71.8% and a specificity of 100% (95% CI: 66.4%-71.8%. Of the 77 syphilis cases, 43 (56% were HIV positive and the sensitivity and specificity of the PCR test did not vary by HIV status. The PCR test was able to detect up to five (10% primary infections that were initially seronegative, including one HIV positive man with delayed seroconversion to syphilis (72 to 140 days and one HIV positive man who did not seroconvert to syphilis over 14 months follow-up. Both men had been treated for syphilis within a week of the PCR test. Conclusions T pallidum PCR is a potentially powerful tool for the early diagnosis of primary syphilis, particularly where a serological response has yet to develop.

    Full Text Available Syphilis in the United States during the 1800s and 1900s had a high prevalence rate causing great concern to health officials. Various measures were taken to control its spread. Mercuric treatments were used up until the introduction of penicillin. The aim of this paper is to determine whether dental abnormalities related to congenital syphilis in individuals who died of syphilis or syphilis-related causes, in the Hamman Todd Osteological Collection, occur and whether mercurial treatment was effective. Hutchinson, Moon and Fournier’s works were analyzed to determine dental abnormalities associated with congenital syphilis and its treatments and used as criteria. Hillson et al. (AJPA,107:25-40 standardized method of description of dental changes was used. In the Hamman Todd Osteological Collection in Cleveland, Ohio, 102 individuals had cause of death recorded in the catalogue as syphilis or lues, and 69 had causes of death relating to syphilis which included paresis (53, aortic insufficiency (15 and pericarditis (1. Thus altogether 171 individuals were studied. Dentition was examined to determine if dental abnormalities associated with congenital syphilis and its treatments were present in individuals not recorded as having congenital syphilis. Crania were examined for any osteological changes. One individual (2266 demonstrated dental malformations possibly related to the congenital disease itself, while three demonstrated dental abnormalities associated with mercuric treatments in childhood (2118, 2263 and 3097. No remarkable bone pathologies were evident on any skull. The use of pre-penicillin treatment of congenital syphilis may have been effective to maintain health into adulthood but not always in eradicating the infection. Effects of mercury on enamel formation and bone changes, need to be considered when making a differential diagnosis of syphilis/congenital syphilis.

    Use of treponemal tests to screen for syphilis (caused by Treponema pallidum pallidum) poses challenges with infection status classification, especially in settings where other treponemal infections are endemic. This study aimed to determine the validity of the syphilis surveillance testing strategy implemented since 2004 using two treponemal tests, and estimate the seroprevalence of active syphilis infection in Ghana where yaws (caused by Treponema pallidum pertenue) is endemic. We retested sera from the 2007 HIV sentinel survey (HSS) using a traditional algorithm, quantitative rapid plasma reagin test followed by qualitative Treponema pallidum haemagglutination assay. The adjusted seroprevalence of active syphilis was calculated by applying the proportions of active syphilis within identified categories of HSS samples during the retesting, to the entire population of HSS samples. The 95% confidence intervals (CIs) were calculated for each proportion, and the t-test was used to assess differences in proportions. Of 2,214 samples that were retested, 203 (9.2%) had active syphilis infection, 21 (0.9%) were biological false reactions, 640 (28.9%) were past or treated syphilis infections, and 1,350 (61%) were uninfected. The current syphilis testing strategy overestimated the seroprevalence of active syphilis infection by a third (HSS versus traditional algorithm: 6.0% (95% CI: 5.6-6.3) vs. 4.5% (95% CI: 4.2-4.8); p syphilis infection. More than half (51.9%) of HSS syphilis positive cases were actually past/treated treponemal infections, possibly previous exposure to yaws. There is an urgent need to review the current syphilis sentinel surveillance testing strategy in Ghana in the context of concurrent endemic treponematoses, to better inform policy.

    We describe herein a woman who developed subcutaneous gummas in her trochanteric regions, bilaterally, although she had been treated for syphilis two decades earlier. Evidence of Treponema pallidum latent late infection was the presence of IgG antibodies against T. pallidum and the positive non-treponemal and treponemal tests. Moreover, immunohistochemical staining for T. pallidum detected some spirochetes close to the atrophic adipocytes allowing the diagnosis of lypo-atrophic panniculitis tertiary syphilis. This is the first case of tertiary syphilis presenting as panniculitis in an immunocompetent patient, demonstrating that subcutaneous fat may be another organ infected in tertiary syphilis.

Ses formes cliniques sont polymorphes et orientent a tord vers d�autres pathologies surtout en periode neonatale. Le diagnostic n�est donc pas toujours facile. La revelation d�une syphilis congenitale par une fracture spontanee est exceptionnellement decrite. Nous rapportons dans ce travail le cas d�un nourrisson de 2 mois ramene en consultation pour limitation douloureuse des mouvements du bras droit.

    Full Text Available Syphilis is a venereal disease. Morocco has witnessed syphilis since the fifteenth century and the treatment of this disease remained archaic until the Protectorate was established.With the establishment of the colonial system in Morocco, the phenomenon of prostitution spread. Protectorate authorities designated a particular place in Casablanca for such activity that developed: Bousbir district. The authorities’ efforts failed to regulate and organize such activity because of the development of clandestine prostitution in relation to urban growth and the increase of employed, poor and downgraded urban population, especially among women who practice prostitution, and due to lack of a real social policy of the Protectorate concerning the policy of land-use planning or control that were a priority.

    Full Text Available Here we report the occurrence of pale yellowish perivascular preretinal dots in 12 patients with ocular syphilis. A case series of these patients was examined between March and October 2012 at the Uveitis Sector of Universidade Federal de São Paulo. After diagnostic confirmation of syphilis, fundus photographs and optical coherence tomography (OCT were performed to verify the localization of the dots, and patients were treated with IV crystalline penicillin for 14 days. The study comprised 11 men (91.6%, 19 eyes, median presentation age of 38.1 years, and panuveitis as the main clinical manifestation (seven patients, 58.3%, being bilateral in four. Ten patients were taking oral prednisone (83.3%. Serum panels performed by the Venereal Disease Research Laboratory (VDRL showed positive results in eight patients (66.7%, whereas VDRL cerebrospinal fluid (CSF tests were negative in seven of nine collected (77.8%. However, serum FTA-Abs was positive in 100% of patients, and eight patients (66.7% had HIV infection. The best corrected visual acuity (BCVA presented after treatment improved in 10 eyes (55.6%, did not change in seven eyes (38.9%, and worsened in one eye (5.6%. Although not yet acknowledged in the literature as a typical manifestation of ocular syphilis, these are very common findings in clinical practice. We believe that preretinal dots are due to perivasculitis secondary to treponema infection. It is important recognize them and remember that syphilis can present in several forms, including the one presented in this study.

    Serological tests' limitations in syphilis diagnosis as well as numerous test interpretations mean that patients with discordant serology results can present diagnostic and treatment challenges for clinicians. We analyzed three common diagnostic algorithms for detecting suspected syphilis in high-prevalence populations in Slovenia. The prospective study included a total of 437 clinical serum samples from adults throughout Slovenia tested with Rapid Plasma Reagin (RPR), Treponema pallidum hemagglutination (TPHA), and an automated chemiluminescence immunoassay (CIA) according to the manufacturer's instructions. In addition to percent agreement, kappa coefficients were calculated as a secondary measure of agreement between the three algorithms. Overall, of 183 subjects that had seroreactive results, 180 were seroreactive in both the reverse sequence and the European Centre for Disease Prevention and Control (ECDC) algorithm. The traditional algorithm had a missed serodiagnosis rate of 30.0%, the overall percent agreement between the traditional and the reverse algorithm (or the ECDC algorithm) was 87.6%, and the kappa value was 0.733. However, the reverse and ECDC algorithm failed to detect three subjects with positive serodiagnosis determined by additional confirmative treponemal assays. Our results supported the ECDC algorithm in the serodiagnosis of syphilis in high-prevalence populations and the use of nontreponemal serology to monitor the response to treatment.

    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. A 44-year-old man who suffered with low back pain for 6 months and progressive radiating pain at lower extremity for 1 week. Radiologic findings showed osteolytic lesion and new bone formation in the parts of the bodies of L4 and L5. Serum treponema pallidum hemagglutination (TPHA) test was positive. A surgery of posterior debridement, interbody and posterolateral allograft bone fusion with instrumentation from L3 to S1 was performed. The low back pain and numbness abated after operation. But the follow-up radiographs showed absorption of the bone grafts and failure of instrumentation. A Charcot's arthropathy was formed between L4 and L5. It is challenging to diagnose the tertiary syphilis in the spine. Surgery is a reasonable auxiliary method to antibiotic therapy for patients who suffered with neuropathy. Charcot's arthropathy should be considered as an operative complication.

    Automated Treponema pallidum-specific chemi-luminescence immunoassays (CLIA) run on random-access analyzers allow for rapid diagnosis of syphilis infection. We evaluated the LIAISON Treponema Screen (LIA) and the ARCHITECT Syphilis TP (ARCH) in comparison to the Treponema pallidum particle agglutination (TPPA) test, as a screening test for syphilis. We performed a prospective study using 577 sera submitted for diagnosis of syphilis, including 318 samples from pregnant women. In addition, 42 stored sera from 32 patients with clinically and serologically characterized syphilis infection were investigated. In the prospective study, the sensitivity and specificity of LIA, ARCH, and TPPA were 100% (18/18), 100% (17/17), and 100% (18/18), and 100% (558/558), 99.8% (552/553), and 99.6% (556/558), respectively. In pregnant women, the specificity of LIA and ARCH was 100% (317/317) and of TPPA 99.7% (316/317). One sample from a child with assumed exposure to maternal antitreponemal antibodies was omitted from analysis. LIA, ARCH, and TPPA were also positive in all investigated sera from patients with known syphilis. Both automated CLIA demonstrated excellent diagnostic sensitivity and specificity when evaluated as a screening test for syphilis under routine conditions of a diagnostic laboratory. Thus, these may be used independently as an alternative to the manual TPPA screen.

    Full Text Available Introduction. Undiagnosed and untreated syphilis in pregnancy may result in subsequent complications: early fetal loss, stillbirth, low birth weight of infants and newborns with congenital syphilis. Objective. To analyze diagnostic and therapeutic dilemmas of positive results of serological tests for syphilis (STS in pregnancy. Case reports. We present two cases of pregnant women, hospitalized in our department due to positive results of serological tests for syphilis, performed during the antenatal visit. On the basis of patients' history, physical examination and STS results, early latent syphilis was diagnosed in the first patient; biological false positive reactions were considered in the second one. Both patients received procaine penicillin treatment. Conclusions. Screening for syphilis in pregnancy as a part of antenatal care and appropriate treatment with penicillin are the most effective interventions to prevent complications of syphilis in pregnancy. It is also important to adapt modern European Guidelines for management of syphilis to Polish conditions.

    This study aimed to estimate the prevalence of syphilis and HIV infection during pregnancy, the mother to child transmission of syphilis and the incidence of congenital syphilis in incarcerated women in Brazil; to compare these rates to those observed in pregnant women outside of jail; and to verify the maternal factors associated with syphilis infection during pregnancy in free and incarcerated women. We used data from two nationwide studies conducted during the period 2011-2014. The Birth in Brazil study included 23,894 free women cared for in 266 hospitals. The Maternal and Infant Health in Prisons study included 495 incarcerated pregnant women or mothers living with their children, according to a census conducted in 33 female prisons. The same case definitions and data collection methods were used in both studies. The chi-square test was used to compare the characteristics of incarcerated and free women with a significance of 0.05. For incarcerated women, the estimated prevalence of syphilis during pregnancy was 8.7% (95%CI: 5.7-13.1) and for HIV infection 3.3% (95%CI: 1.7-6.6); the estimated mother to child transmission of syphilis was 66.7% (95%CI: 44.7-83.2) and the incidence of congenital syphilis was 58.1 per 1,000 living newborns (95%CI: 40.4-82.8). Incarcerated women had a greater prevalence of syphilis and HIV infection during pregnancy, lower quality of antenatal care and higher levels of social vulnerability. Syphilis infection showed to be an indicator of social vulnerability in free women, but not in incarcerated women. Health initiatives in prison are necessary to reduce healthcare inequalities and should include adequate antenatal and birth care.

    Full Text Available ABSTRACT OBJECTIVE We aim to analyze trend of syphilis and factors associated with recurrent episodes of syphilis among adults and adolescents attended in a STI/AIDS reference centers in Campinas, state of São Paulo, 2004 to 2012. METHODS Medical records, pharmacy data, and notification database were accessed to analyze trends of syphilis and sociodemographic, epidemiological and clinical variables associated with reinfection of syphilis. After univariate analysis, a hierarchical logistic regression model was adjusted to analyze variables associated with more than one episode of syphilis (dependent variable. First step (sex, age, and years of schooling were tested and in the second, epidemiological and clinical variables. RESULTS A total of 1,009 episodes of syphilis were identified among 860 adolescents and adults, 117 individuals (13.6% presented with more than one episode of syphilis. Factors associated with more than one episode of syphilis were sex (male (OR = 4.28; 95%CI 1.31–14.0, age (OR = 1.02; 95%CI 1.00–1.04, homosexual/bisexual orientation (OR = 2.29; 95%CI 1.22–4.32, HIV coinfection (OR = 3.54; 95%CI 2.22–5.63, and absence of STI symptoms at the time of syphilis diagnostic (OR = 1.70; 95%CI 1.03–2.80. CONCLUSIONS The number of cases of syphilis and proportion in relation to STI increased in recent years in a specific population attended in a STI/AIDS reference centers in Campinas. Association with HIV, homosexual/bisexual orientation and the silent clinical characteristic of cases confirm the necessity to implement more aggressive strategies to prevent the occurrence of syphilis and other STI in specific populations with higher disease risk.

    Full Text Available Abstract Background Early diagnosis of syphilis and timely treatment can effectively reduce ongoing syphilis transmission and morbidity. We examined the factors associated with the early diagnosis of syphilis to inform syphilis screening strategic planning. Methods In an observational study, we analyzed reported syphilis cases in Guangdong Province, China (from 2014 to mid-2015 accessed from the national case-based surveillance system. We categorized primary and secondary syphilis cases as early diagnosis and categorized latent and tertiary syphilis as delayed diagnosis. Univariate analyses and multivariable logistic regressions were performed to identify the factors associated with early diagnosis. We also examined the factors associated with early diagnosis at the individual and city levels in multilevel logistic regression models with cases nested by city (n = 21, adjusted for age at diagnosis and gender. Results Among 83,944 diagnosed syphilis cases, 22% were early diagnoses. The city-level early diagnosis rate ranged from 7 to 46%, consistent with substantial geographic variation as shown in the multilevel model. Early diagnosis was associated with cases presenting to specialist clinics for screening, being male and attaining higher education level. Cases received syphilis testing in institutions and hospitals, and diagnosed in hospitals were less likely to be in early diagnosis. At the city-level, cases living in a city equipped with more hospitals per capita were less likely to be early diagnosis. Conclusions To enhance early diagnosis of syphilis, city-specific syphilis screening strategies with a mix of passive and client/provider-initiated testing might be a useful approach.

    Full Text Available Background: Use of rapid diagnostic tests for HIV and syphilis has increased remarkably in the last decade. As new rapid diagnostic tests become available, there is a continuous need to assess their performance and operational characteristics prior to use in clinical settings. Objectives: In this study, we evaluated the performance of the Chembio Dual Path Platform (DPP® HIV–Syphilis Assay to accurately diagnose HIV, syphilis, and HIV/syphilis co-infection. Method: In 2013, 990 serum samples from the Georgia Public Health Laboratory in Atlanta, Georgia, United States were characterised for HIV and syphilis and used to evaluate the platform. HIV reference testing combined third-generation Enzyme Immunoassay and Western Blot, whereas reference testing for syphilis was conducted by the Treponema pallidum passive particle agglutination method and the TrepSure assay. We assessed the sensitivity and specificity of the DPP assay on this panel by comparing results with the HIV and syphilis reference testing algorithms. Results: For HIV, sensitivity was 99.8% and specificity was 98.4%; for syphilis, sensitivity was 98.8% and specificity was 99.4%. Of the 348 co-infected sera, 344 (98.9% were detected accurately by the DPP assay, but 11 specimens had false-positive results (9 HIV and 2 syphilis due to weak reactivity. Conclusion: In this evaluation, the Chembio DPP HIV–Syphilis Assay had high sensitivity and specificity for detecting both HIV and treponemal antibodies. Our results indicate that this assay could have a significant impact on the simultaneous screening of HIV and syphilis using a single test device for high-risk populations or pregnant women needing timely care and treatment.

    A worldwide syphilis incidence increase was recorded at the beginning of the new millennium, occurring primarily among men who have sex with men (MSM). The aim of this study was to analyse the epidemiological situation of syphilis in the Belgrade population between 2005 and 2014 and to examine the characteristics of an early syphilis outbreak among MSM in Belgrade in 2014. Reporting of syphilis is compulsory in Serbia. Routinely reported data were analysed along with data collected from patients' charts. During the period observed, syphilis incidence increased from 1.07 per 100,000 in 2005 to 4.1 per 100,000 in 2014 (383.2%). From 2005 to 2009, syphilis rates in Belgrade were low, around 1 case per 100,000 people. The first outbreak was registered in 2010. The new incidence increase happened in 2012, and again in 2014 when it was the highest. These incidence changes were registered mainly in men, where the frequency of syphilis was much higher than in women. In 2014, primary syphilis was diagnosed in 20 cases, secondary syphilis in 42, and early latent syphilis in 9 patients. Fifty-seven were MSM, 10 were heterosexual men and 4 were women. Twenty-four cases, all MSM were co-infected with HIV. Majority of patients acquired infection in Belgrade, while in 42/71 cases oral sex was the only risk factor. In comparison with HIV negative, HIV positive syphilis patients were older, more frequently unemployed and MSM. They also more frequently had sex with unknown partners and were diagnosed in the secondary stage of infection. Study results underline the need for coordinated and expeditious surveillance, partner services, enhanced screening of population at risk, health education, as well as early diagnosis and treatment.

    Congenital syphilis is transmitted through the placenta by the infected mother after 16 weeks of gestation. Since the incidence of syphilis is again on the increase, syphilis remains at the present time a public problem of major and increasing proportions. Recently, congenital syphilis has different formas of presentation. The authors observed clinically and radiologically 27 cases of congenital syphilis in the neonates and infants treated at the pediatric ward of Chonnam National University Hospital from Jan. 1977 to Mar. 1982. The results are as follows: 1. The number of observed patients was 27 cases, 22 cases in male, 5 cases in female. 2. Onset of first clinical symptoms and signs was within the 4th week life in 14 cases (52%), 1-2 months in 6 cases (22%), 2-3 months in 4 cases (15%), 3-4 months in 3 cases (11%). All cases was within 6 months. 3. The order of the frequency of common clinical manifestations was hepatomegaly (96%), splenomegaly (78%), skin lesion (63%), anemia (63%), nasal snuffle (56%). 4. Of 11 cases with known birth weight, 10 cases were low birth weight. 5. The serologic test (VDRL slide test) of 27 tested caes revealed reactive response in 26 cases, non-reactive response in 1 case, and that of syphilitic mothers except one revealed reactive in 23 cases, non- reactive in 3 cases. 6. Roentgenographic syphilitic bony changes were detected in 26 cases (96%), of 27 studied cases, osteochondritis was present in 24 cases (89%), periostitis in 21 case (78%), osteomyelitis in 11 cases (41%). 7. The most common sites affected were as follows. Radius and ulna were the most frequently affected, the next were in order of tibia and fibula. Considering osteochondiritis only, the distal end of radius and ulna (78% respectively) and proximal end of tibra (67%) were the most frequently affected sites, the proximal end of femur (33%) was least frequently affected site. 8. On chest films of 27 case, osseous changes (mainly periostitis) of clavicle were noted

    To analyze the midterm evaluation data from the National Syphilis Prevention and Control Plan (2010-2020) and evaluate the current status of syphilis prevention and control in Jiangsu province, China. We collected data via (1) field surveys conducted in 2015 and (2) data recorded in existing syphilis surveillance systems. We conducted descriptive statistical analysis to evaluate the current landscape of syphilis control initiatives and their potential effect in syphilis control. The incidence of all cases of syphilis decreased from 2010 (32.3 per 100,000) to 2015 (30.1 per 100,000), with an annual growth of -1.17% (x2trend = -7.52, Psyphilis and congenital syphilis both decreased significantly from 2010 to 2015. The average awareness rate of syphilis knowledge among professional personnel was 95.4% (3781/3963). Rural residents had the lowest awareness rate (83.5%, 1875/2245) and commercial sex workers had the highest awareness rate (92.1%, 7804/8474) in 2015. Only 47.8% (33908/70894) of patients received provider-initiated syphilis counseling and testing (PISTC) services in sexually transmitted disease (STD) clinics, but 94.5% (87927/93020) of all syphilis patients received free testing for syphilis. Overall, 97.2% (9378/9648) of syphilis reported cases of syphilis at medical institutions were confirmed to be accurate, and 92.2% (5850/6345) of patients diagnosed with syphilis at medical institutions received treatment with penicillin. The syphilis incidence rate in Jiangsu has decreased in recent years, but remains at a high level. It is essential to promote PISTC services to improve knowledge of syphilis and rates of testing and treatment in Jiangsu province.

    The aim of this work was to investigate the application of the nested PCR assay for the detection of Treponema pallidum (TP) DNA from the blood of patients with different stages of syphilis. In this study, a nested PCR method targeting the Tpp47 and polA genes (Tpp47-Tp-PCR and polA-Tp-PCR) was developed to detect TP-DNA in whole blood samples collected from 262 patients with different stages of syphilis (84 primary syphilis, 97 secondary syphilis, and 81 latent syphilis patients). The PCR assay detected T. pallidum DNA in 53.6% and 62.9% of the patients with primary and secondary syphilis, respectively, which was much higher than the detection levels in patients with latent syphilis (7.4%) (both p PCR in the early phase of the latent infection. Thus, blood RPR titers were correlated with the blood T. pallidum burden, but the correlations varied with primary and secondary syphilis. The results indicate that nested PCR is a sensitive method for detecting blood TP-DNA and is especially useful for detecting early syphilis including primary syphilis and secondary syphilis. The findings also suggest that the PCR assay may be used to complement other methods to enhance the diagnosis of syphilis.

    To promote regular syphilis testing among men who have sex with men in San Francisco, a social marketing campaign, Dogs Are Talking, was created. An evaluation of the campaign found no difference in syphilis testing among men who recalled the campaign and those that did not. A significant difference was seen among HIV-infected men.

    Acute periostitis affecting the long bones is a characteristic but uncommon manifestation of syphilis in the adult with an early acquired infection. This report describes the history of a jogger who developed acute localized periostitis of the shaft of both tibiae during the early stage of acquired syphilis. Symptomatology was initially attributed to the medial tibial stress syndrome.

    Conclusions: AIDS mortality may have played an important role in the decline in syphilis in this region. Consequently, with AIDS deaths declining in Sub-Saharan Africa, vigilant surveillance of syphilis prevalence will be necessary to detect a potential re-emergence, as has occurred in high-income countries, and to render a timely public health response.

    To describe the clinical and epidemiological characteristics of syphilis in men who have sex with men (MSM) in an area of Mallorca, Spain. We performed a retrospective analysis of syphilis cases in MSM seen at a hospital in Mallorca between January 2005 and June 2013. Fifty-five cases of syphilis were recorded in MSM during the study period (34.3% of all cases diagnosed), and 74.5% of these patients had human immunodeficiency virus (HIV) coinfection. The two diseases had been diagnosed simultaneously in 70.7% of this population. Patients with HIV coinfection had a median CD4 count of 456cells/μL (range, 29-979 cells/μL). Syphilis was diagnosed clinically in 49.1% of cases and by screening in the remaining 50.9%. The most common form of syphilis was late latent or indeterminate syphilis (41.9% of cases). In the group of men with syphilis, MSM had a higher risk of HIV infection. A majority of MSM with syphilis had HIV coinfection. HIV screening is therefore essential in this population and could even result in early diagnosis. Copyright © 2015 Elsevier España, S.L.U. and AEDV. All rights reserved.

    Full Text Available The World Health Organization initiative to eliminate mother-to-child transmission of syphilis aims for ≥ 90% of pregnant women to be tested for syphilis and ≥ 90% to receive treatment by 2015. We calculated global and regional estimates of syphilis in pregnancy and associated adverse outcomes for 2008, as well as antenatal care (ANC coverage for women with syphilis.Estimates were based upon a health service delivery model. National syphilis seropositivity data from 97 of 193 countries and ANC coverage from 147 countries were obtained from World Health Organization databases. Proportions of adverse outcomes and effectiveness of screening and treatment were from published literature. Regional estimates of ANC syphilis testing and treatment were examined through sensitivity analysis. In 2008, approximately 1.36 million (range: 1.16 to 1.56 million pregnant women globally were estimated to have probable active syphilis; of these, 80% had attended ANC. Globally, 520,905 (best case: 425,847; worst case: 615,963 adverse outcomes were estimated to be caused by maternal syphilis, including approximately 212,327 (174,938; 249,716 stillbirths (>28 wk or early fetal deaths (22 to 28 wk, 91,764 (76,141; 107,397 neonatal deaths, 65,267 (56,929; 73,605 preterm or low birth weight infants, and 151,547 (117,848; 185,245 infected newborns. Approximately 66% of adverse outcomes occurred in ANC attendees who were not tested or were not treated for syphilis.

    Background Syphilis is concentrated among high-risk groups, but the epidemiology of syphilis reinfection is poorly understood. We characterized factors associated with syphilis incidence, including reinfection, in a high-risk cohort in Peru. Methods Participants in the NIMH CPOL trial were assessed at baseline and 2 annual visits with HIV/STI testing and behavioral surveys. Participants diagnosed with syphilis also attended 4- and 9-month visits. All participants underwent syphilis testing with RPR screening and TPPA confirmation. Antibiotic treatment was provided according to CDC guidelines. Reinfection was defined as a 4-fold titer increase or recurrence of seroreactivity after successful treatment with subsequent negative RPR titers. The longitudinal analysis used a Possion generalized estimating equations model with backward selection of variables in the final model (criteria P <0.02). Results Of 2,709 participants, 191 (7.05%) were RPR-reactive (median 1:8, range 1:1–1:1024) with TPPA confirmation. There were 119 total cases of incident syphilis, which included both reinfection and first-time incident cases. In the bivariate analysis, the oldest 2 quartiles of age (incidence ratio (IR) 3.84; P <0.001 and IR 8.15; P <0.001) and being MSM/TW (IR 6.48; P <0.001) were associated with higher risk of incident syphilis infection. Of the sexual risk behaviors, older age of sexual debut (IR 12.53; P <0.001), not being in a stable partnership (IR 1.56, P = 0.035), higher number of sex partners (IR 3.01; P <0.001), unprotected sex in the past 3 months (IR 0.56; P = 0.003), HIV infection at baseline (IR 3.98; P <0.001) and incident HIV infection during the study period (IR 6.26; P = 0.003) were all associated with incident syphilis. In the multivariable analysis, older age group (adjusted incidence ratio (aIR) 6.18; P <0.001), men reporting having sex with a man (aIR 4.63; P <0.001), and incident HIV infection (aIR 4.48; P = 0.008) were significantly associated

    Objective: To estimate HIV seroprevalence among pregnant women with syphilis and evaluate the influence of syphilis infection on mother-to-child-transmission (MTCT) of HIV by meta-analysis. Methods: We conducted a systematic literature search for 1 678 articles related to maternal syphilis and HIV infection published until October 1 st 2015 using the PubMed, Web of Science, Chinese Web of Knowledge, Wanfang, Weipu, and SinoMed databases and evaluated the quality of each papers using the STROBE checklist, and the keywords were " pregnant women/maternal/pregnancy" , "syphilis/AIDS" , "HIV/human immunodeficiency virus" , "mother- to-child transimission/vertical transmission" . Excluding studies with the special subgroups of HIV-positive pregnant women as the research objects, review or meeting abstract, impossibility of full-text acquisition, sample size HIV seroprevalence among pregnant women with syphilis and the RR of MTCT for women infected with both syphilis and HIV. Subgroup analyses were undertaken by study location, sample size, use of anti-retroviral therapy and study quality. Results: Sixteen studies with a combined sample of 110 573 pregnant women were included in the analysis. Of these, ten reported HIV seroprevalences among pregnant women with syphilis and six studies evaluated the influence of syphilis infection on MTCT of HIV. Pooled estimates yielded a HIV seroprevalence of 11.6% (95 % CI : 6.7%-19.5%) among pregnant women with syphilis. We estimated that the risk of MTCT of HIV was 1.86 times ( RR= 1.86, 95 % CI : 0.89%-3.89%) higher among pregnant women with syphilis compared with those only infected with HIV-although this effect was not statistically significant. Cochran's Q test showed a high degree of heterogeneity in estimates of HIV seroprevalence and the effect of syphilis infection on MTCT of HIV across studies ( I 2 =89.4% and 86.2%, respectively, PHIV seroprevalences of 24.9% (95 %CI : 17.4%-34.3%) in Africa, 2.8% (95 % CI : 1.4%-5.6%) in

    Objectives Untreated maternal syphilis leads to adverse pregnancy outcomes. The use of point of care tests (POCT) offers an opportunity to improve screening coverage for syphilis and other aspects of health systems. Our objective is to present the experience of the introduction of POCT for syphilis in Peru and describe how new technology can catalyze health system strengthening. Methods The study was implemented from September 2009–November 2010 to assess the feasibility of the use of a POCT for syphilis for screening pregnant women in Lima, Peru. Outcomes measured included access to syphilis screening, treatment coverage, partner treatment, effect on patient flow and service efficiency, acceptability among providers and patients, and sustainability. Results Before the introduction of POCT, a pregnant woman needed 6 visits to the health center in 27 days before she received her syphilis result. We trained 604 health providers and implemented the POCT for syphilis as the “two for one strategy”, offering with one finger stick both syphilis and HIV testing. Implementation of the POCT resulted in testing and treatment on the first visit. Screening and treatment coverages for syphilis improved significantly compared with the previous year. Implementation of POCT has been scaled up nationally since the study ended, and coverages for screening, treatment and partner treatment have remained over 92%. Conclusions Implementation of POCT for syphilis proved feasible and acceptable, and led to improvement in several aspects of health services. For the process to be effective we highlight the importance of: (1) engaging the authorities; (2) dissipating tensions between providers and identifying champions; (3) training according to the needs; (4) providing monitoring, supervision, support and recognition; (5) sharing results and discussing actions together; (6) consulting and obtaining feedback from users; and (7) integrating with other services such as with rapid HIV

    Diagnosis of syphilis is difficult. Follow-up and therapy evaluation of syphilitic patients are poor. Little is known about positron emission tomography (PET) in syphilis. This review was to systematically review usefulness of PET for diagnosis, disease extent evaluation, follow-up, and treatment response assessment in patients with syphilis. We searched PubMed, EMBASE, SCOPUS, Cochrane Library, Web of Science, ClinicalTrials.gov, and three Chinese databases (SinoMed, Wanfang, and CNKI) for English and Chinese language articles from inception to September 2016. We also collected potentially relevant studies and reviews using a manual search. The search keywords included the combined text and MeSH terms "syphilis" and "positron emission tomography". We included studies that reporting syphilis with a PET scan before and/or after antibiotic treatment. The diagnosis of syphilis was based on serological criteria or dark field microscopy. Outcomes include pre- and post-treatment PET scan, pre- and post-treatment computed tomography, and pre- and post-treatment magnetic resonance imaging. We excluded the articles not published in English or Chinese or not involving humans. Of 258 identified articles, 34 observational studies were included. Thirty-three studies were single-patient case reports and one study was a small case series. All patients were adults. The mean age of patients was 48.3 ± 12.1 years. In primary syphilis, increased fluorodeoxyglucose (FDG) accumulation could be seen at the site of inoculation or in the regional lymph nodes. In secondary syphilis with lung, bone, gastrointestinal involvement, or generalized lymphadenopathy, increased FDG uptake was the most commonly detected changes. In tertiary syphilis, increased glucose metabolic activity, hypometabolic lesions, or normal glucose uptake might be seen on PET. There were five types of PET scans in neurosyphilis. A repeated PET scan after treatment revealed apparent or complete resolution of the

    To examine changes over time in the distribution of primary and secondary syphilis cases across states, using Lorenz curves and Gini coefficients. For each year from 1985 to 2007, the Gini coefficient for the state-level distribution of male and female syphilis cases was calculated. The Gini coefficient can range from 0 (indicating equality in syphilis rates across states) to 1 (indicating complete inequality such that all syphilis cases occur in one state). The Gini coefficients for men are notably lower (indicating more equality in the distribution of syphilis across states) in recent years (in which men who have sex with men (MSM) account for most syphilis cases) than in the heterosexual epidemic of the late 1980s and early 1990s. Although syphilis rates in men were similar in 1995 and 2007 (6.7 and 6.6 per 100,000, respectively), the Gini coefficient for male syphilis decreased from 0.523 in 1995 to 0.333 in 2007. For syphilis in women, Gini coefficients have not shown the same degree of decline. The spread of MSM syphilis cases to urban areas across the nation is likely to be a main cause of the decreased concentration of male syphilis cases across states from 1995 to 2007.

    Congenital syphilis is one of the preventable diseases caused by the gram-negative bacteria Treponema pallidum; yet, it imposes a serious global health and economic burden, with more than half of the cases resulting in serious adverse outcomes, including infant mortality. Mother-to-child transmission (MTCT) of syphilis is estimated at 3.6 million adjusted life years (DALYs) and around $309 million in medical costs. In 2006, an estimated 9.7 million children of age less than five years died in developing countries; almost four million were neonatal deaths. There were 3.2 million stillbirths globally, among whom 95% were in the developing countries. In sub-Saharan Africa, there is an estimated 2.7% (0.1%-10.3%) of pregnant women infected with syphilis, representing more than 900,000 pregnancies at risk each year. There were many non-specific and specific diagnostic tests used in the past, which required laboratory equipment and electricity, but there are many newer tests available now that provide rapid results with high sensitivity and specificity, e.g., the immunochromatographic strip (ICS) and rapid syphilis tests (RST). Early syphilis can be completely eliminated with a single injection of penicillin, which is readily available, cheap, and highly effective, and treating pregnant women with penicillin is 98% effective at preventing congenital syphilis. Targeting women at a high risk of having syphilis makes universal screening in antenatal programs the most efficacious way to prevent syphilis-associated morbidity and mortality. The potential for a program to prevent congenital syphilis in the perinatal, neonatal, and postnatal periods is evident. While considering resource allocation to child survival programs in areas where the prevalence of syphilis is high, officials need to include antenatal syphilis screening, using rapid tests and treatment at the first contact of the mother with the health care system. In countries like Zambia and other resource

    Annual screening for syphilis is indicated for all sexually active men who have sex with men (MSM). Using National HIV Behavioral Surveillance data from 2008, 2011, and 2014, we assessed trends in self-reported syphilis testing and diagnoses in the past 12 months among MSM. We calculated percentages of syphilis screening and diagnosis by selected characteristics for each year. Trends were assessed using Poisson regression models with generalized estimation equations. Analysis of syphilis diagnosis was limited to participants who reported syphilis screening. Analysis included data from 28,295 sexually active MSM. Overall, 49% of MSM interviewed in 2014 reported syphilis screening, a significant increase from 40% in 2011 and 38% in 2008. In 2014, syphilis screening was most commonly reported by MSM who were aged 25-29 years (56%), HIV positive (68%), and had >10 sexual partners in the past 12 months (65%). The largest increases in syphilis screening between 2008 and 2014 were among MSM aged 30-39 years (37%-52%) and MSM who reported >10 sex partners (48%-65%). Among MSM who reported syphilis screening, the diagnoses of syphilis increased from 9% in 2008 to 11% in 2014. Increases in syphilis diagnosis were observed among MSM who were aged 25-29 years (6%-10%), black (9%-14%), HIV positive (15%-21%), and reported >10 sexual partners (11%-17%). Although syphilis screening among MSM increased during 2008-2014, less than half of MSM reported recent syphilis screening in 2014. Given continued increases in syphilis among MSM, innovative interventions are needed to improve compliance with screening recommendations.

    Full Text Available BACKGROUND Syphilis is one of the major sexually transmitted infections, which is showing a raising trend across the globe. The aim of the study is to study the prevalence of syphilis among Sexually Transmitted Infection (STI clinic attendees of a tertiary care hospital of south India. MATERIALS AND METHODS This was a cross-sectional study of one year duration conducted at STI clinic of a government tertiary hospital in South India. Patients who have been diagnosed to have syphilis were analysed with respect to demographic profile and their sexual behaviour pattern. RESULTS 40 were persons diagnosed to have syphilis among a total of 1790 STI clinic attendees. The mean age of patients with syphilis found to be 31 years. Male-to-female ratio is 7:1. 80% of patients with syphilis had higher school level and college level education. Homosexual behaviour pattern was predominant and it was found among 60% of them (p value 0.011. 62.5% of them were alcoholic. Safe sex practices were minimal in spite of knowledge about condom. CONCLUSION There was a raising trend of syphilis among STI clinic attendees during 2016. Early infectious stage of disease is more and was found more commonly among Men Having Sex with Men (MSM.

    To determine the epidemiological profile of gestational syphilis and associated factors in a Peruvian population. The study is a secondary analysis of data obtained from public hospitals in Peru for the 2000-2010 period. 652,636 pregnant women were included from 37 cities and 45 health centers in Peru. The prevalence of gestational syphilis was 0.7%, while 80.7% reported screening for gestational syphilis. The highest prevalence of maternal syphilis is found in the lowland rainforest followed by the highland rainforest. In the three regions of Peru decreased prevalence of gestational syphilis has been seen throughout the years. The prevalence for 2010 are 0.2% on the coast, in the highlands 0.23% and 0.47% in the jungle. The lack of education and prenatal care, high parity, cohabiting or single, and living in the jungle, are associated with having a positive syphilis test. The results suggests that prevalence of gestational syphilis has declined over the decade 2000-2010.

    Although systematic reviews of epidemiologic studies have been conducted for condom use and the risk of several sexually transmitted diseases, there have been no such reviews for condom use and syphilis. A systematic literature review of epidemiologic studies published from 1972 to 2008 was conducted to evaluate study methods and measures of association reported for condom use and risk of syphilis. All 12 included studies had significant methodologic limitations. Nine (75%) studies were cross-sectional. Although 11 (92%) studies assessed consistent condom use, no studies assessed correct use or condom use problems, nor did any document exposure to a partner infected with syphilis. Ten studies had insufficient information to distinguish prevalent from incident infections. Two studies that assessed both incident infection and consistent condom use suggested a reduced risk of syphilis with consistent condom use; 1 study was statistically significant. Significant methodologic limitations exist for all reviewed studies of syphilis and condom use. Among the 2 most rigorously designed studies, both suggested a reduced risk of syphilis with consistent condom use. Additional studies incorporating rigorous methods are needed to further assess the effect of condom use on risk of syphilis.

    During 2012, Christchurch experienced a dramatic increase in cases of infectious syphilis among men who have sex with men. This was accompanied by some novel trends; notably, the acquisition of infection in a younger age group, with local sexual contacts, commonly via the use of social media. This study is a report on an approach to case identification and public health communication as a component of a multifaceted outbreak response. Enhanced syphilis surveillance data on public health responses to outbreaks of sexually transmissible infections was collated and reviewed, alongside clinical records and literature. Reported outbreak response methods were adapted for the Christchurch cohort. A Facebook page was created to raise awareness of infectious syphilis, the importance of screening and where to get tested. Twenty-six males were diagnosed with infectious syphilis in 2012, an increase from previous years, of which 22 reported only male sexual contact. High use of social media used to find potential sexual contacts was reported. Enhanced syphilis surveillance characterised in detail an infectious syphilis outbreak in Christchurch. Index cases were identified, contact tracing mapping was used to identify transmission networks and social media was also used to educate the risk group. There was a decrease in infectious syphilis presentations, with no cases in the last 3 months of 2012.

    The objective of the Syphilis Elimination Project was to decrease the incidence of syphilis in the Hispanic community of Baltimore City through a culturally appropriate health initiative. Both qualitative and quantitative methods were used in the study design. Surveillance data were used to collect testing information. Comparisons at the start and end of the project measured change in individual knowledge about syphilis. Cross-sectional data from interviews with business owners and qualitative comments from outreach workers evaluated perception of program effectiveness. The local health department collected surveillance data. A convenience sample of 63 Hispanic community members, 12 business owners/managers, and 8 outreach workers was utilized throughout the evaluation process. The project was a culturally appropriate approach to health promotion with street and business outreach. Post intervention there was a statistically significant increase in knowledge about syphilis within the Hispanic community and an increase in testing behaviors. The Syphilis Elimination Project was created in response to a marked increase in syphilis in Baltimore among the Hispanic population and a health disparity that existed within the city. It increased community members' knowledge of syphilis and positively influenced testing behaviors.

  2. Current Perspectives on Prevention of Mother-to-Child Transmission of Syphilis

    2016-01-01

    This article aims to provide an update on the prevention of mother-to-child transmission of syphilis by drawing upon some important basic concepts and reviewing the most recent literature on the diagnosis and treatment of syphilis in pregnancy. New technologies, such as automated and point-of-care immunologic tests, are shifting some paradigms, which will certainly be further investigated in the forthcoming years. This is the time to carefully evaluate traditional as well as new strategies to prevent congenital syphilis. Adverse outcomes of mother-to-child transmission of syphilis can be prevented with antenatal screening and penicillin therapy, which proved to have an excellent cost-benefit ratio even in populations with a low prevalence of syphilis. However, syphilis epidemiology is influenced by socioeconomic and cultural factors, and major challenges are faced by poor and developing countries in which the severity of the problem is extremely alarming. On the other hand, the emergence of new technologies has raised doubts about the best algorithm to be used when proper laboratory resources are available. Conditions are quite heterogeneous across populations, and some procedures should not be generalized while there is no evidence that supports some changes and while in-depth studies about local conditions are not conducted. Official organizations need to be alert in order to avoid isolated decisions and ensure that evidence-based guidelines be used in the management of syphilis in pregnancy. PMID:27081586

    to analyse epidemiological, clinical, and analytical features of HIV-infected men who have sex with men (MSM) diagnosed with syphilis in the Infectious Diseases Unit (Hospital Virgen de la Victoria, Málaga, Spain) during 2004-2013. An observational study was conducted on 196 syphilis episodes in 167 MSM infected with HIV (2004-2013). Epidemiological, clinical, and analytical data were collected. Annual syphilis incidence among HIV-MSM is calculated as the number of syphilis episodes among MSM in one year divided by the number of MSM followed up in that year. Incidence ranged from 1.2% (2007) to 7.8% (2012). There were asymptomatic episodes in 42.8% cases, and an HIV-syphilis coincident diagnosis in 28.5%. The annual incidence of syphilis has increased within HIV infected MSM. One third of the syphilis episodes were simultaneous to HIV diagnosis and near half of them were asymptomatic.

    A flocculation reaction employing a cardiolipid antigen was used for syphilis screening on Groupamatic equipment in parallel with conventional screening reactions: Kolmer CF, RPCF, Kahn, Kline, and RPR. The positive samples were confirmed by FTA-200, FTA-ABS, TPI, and in some cases by TPHA. There were 5,212 known samples which had already been tested by all methods and of which 1,648 were positive, and 58,636 screened samples including 65 positives. Half of the samples in the first series were taken without anticoagulant; the remainder were collected in potassium EDTA. The percentage of false positives with the Groupamatic was about 1-4 per cent. The percentage of false negatives among positve (greater than or equal+) samples varied from 0-18 to 1-3 per cent.; on the other hand the sensitivity was less good for samples giving doubtful and/or dissociated reactions in conventional screening reactions. The specificity and sensitivity of this technique are acceptable for a blood transfusion centre. The reproducibility is excellent and the automatic reading of results accurate. Additional advantages are rapidity (340 samples processed per hour); simultaneous performance of eleven other immunohaematological reactions; no contamination between samples; automatic reading, interpretation, and print-out of results; and saving of time because samples are not filed sequentially and are automatically identified when the results are obtained. Although the importance of syphilis in blood transfusion seems small, estimates of the risk are difficult and further investigations are planned. Images PMID:1098731

    Full Text Available 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. Every sample (one per patient was tested with toluidine red unheated serum test (TRUST, T. pallidum particle agglutination assay (TPPA, and Treponema pallidum enzyme immunoassay (TP-EIA according to the manufacturer's instructions. The results of syphilis serological testing were interpreted following different algorithms respectively. We directly compared the traditional syphilis screening algorithm with the reverse syphilis screening algorithm in this unique population. The reverse algorithm achieved remarkable higher seroprevalence of syphilis than the traditional algorithm (24.9% vs. 14.2%, p < 0.0001. Compared to the reverse algorithm, the traditional algorithm also had a missed serodiagnosis rate of 42.8%. The total percentages of agreement and corresponding kappa values of tradition and ECDC algorithm compared with those of reverse algorithm were as follows: 89.4%,0.668; 99.8%, 0.994. There was a very good strength of agreement between the reverse and the ECDC algorithm. Our results supported the reverse (or ECDC algorithm in screening of syphilis in HIV-infected populations. In addition, our study demonstrated that screening of HIV-populations using different algorithms may result in a statistically different seroprevalence of syphilis.

    The objective of this study was to assess the factors associated with methamphetamine (MA) use, syphilis, and unprotected sex among female sex workers from different type of venues in Qingdao City, Shandong Province of China. Three consecutive cross-sectional surveys provided information on demographics, sexual and drug use behaviors, and HIV-related services. Of 1187 participants, 3.0% were infected with syphilis; 30.2% ever used MA; 58.3% ever had unprotected commercial sex in the past month. The prevalence rates of syphilis and MA use were 2.5% and 33.0% for participants recruited from saunas, night clubs, bars or hotels; 2.7% and 28.3% for hair/beauty salon-based participants; and 4.5% and 15.8% for street-based participants. Street-based MA users were more likely to be single, non-Shandong residents, have first lifetime sex act at younger age, and recruited in 2008 (vs. 2006). Saunas, night clubs, bars, or hotels-based MA users were more likely to be younger, sex debut at younger age, have longer duration of sex work, have unprotected commercial sex, and be syphilis-infected. Hair/beauty salon-based MA users were more likely to be non-Shandong residents, younger, and to have unprotected commercial sex. Syphilis among the sauna-, night club-, bar-, or hotel-based participants was associated with MA use and ever receipt of HIV testing. Syphilis among the hair/beauty salon-based participants was associated with longer duration of sex work. MA users who frequent commercial sex venues are engaging in high-risk behaviors and are at risk for syphilis/other sexually transmitted diseases. Better-targeted intervention efforts to curtail the epidemics of MA use and HIV/syphilis should therefore take cognizance of the role of commercial sex venues as focal points of MA use and syphilis/sexually transmitted disease transmission.

    In 2007, the Los Angeles County Department of Public Health launched Check Yourself, a new social marketing campaign, as part of ongoing efforts to address the persistent syphilis epidemic among men who have sex with men (MSM) in the county. The goals of the campaign were to increase syphilis testing and knowledge among MSM. Check Yourself was planned with careful attention to the principles of social marketing, including formative research, market segmentation, and an emphasis on building a strong brand. A cross-sectional survey using a time-location sample was conducted in 2009 for the evaluation. The survey assessed demographics, syphilis knowledge, and recent syphilis testing as well as unaided awareness, aided awareness, and confirmed awareness, meaning that a person had both awareness of the campaign and could correctly identify that the campaign was about syphilis. The total sample size was 306. Unaided awareness for Check Yourself was 20.7%, and aided awareness was 67.5%, bringing total campaign awareness to 88.2%; confirmed awareness was 30.4%. Unaided campaign awareness was associated with syphilis knowledge and important risk behaviors for syphilis, indicating that the campaign reached an appropriate audience. Total awareness was not associated with recent syphilis testing in a multivariate model. However, MSM with confirmed awareness were more than 6 times more likely to have been recently tested. The evaluation of Check Yourself found that the campaign had a very strong brand among MSM. Although total awareness was not associated with syphilis testing, confirmed awareness, a more robust measure, was strongly associated.

  9. Prioritizing congenital syphilis control in south China: a decision analytic model to inform policy implementation.

    Nicholas X Tan

    Full Text Available Syphilis is a major public health problem in many regions of China, with increases in congenital syphilis (CS cases causing concern. The Chinese Ministry of Health recently announced a comprehensive 10-y national syphilis control plan focusing on averting CS. The decision analytic model presented here quantifies the impact of the planned strategies to determine whether they are likely to meet the goals laid out in the control plan.Our model incorporated data on age-stratified fertility, female adult syphilis cases, and empirical syphilis transmission rates to estimate the number of CS cases associated with prenatal syphilis infection on a yearly basis. Guangdong Province was the focus of this analysis because of the availability of high-quality demographic and public health data. Each model outcome was simulated 1,000 times to incorporate uncertainty in model inputs. The model was validated using data from a CS intervention program among 477,656 women in China. Sensitivity analyses were performed to identify which variables are likely to be most influential in achieving Chinese and international policy goals. Increasing prenatal screening coverage was the single most effective strategy for reducing CS cases. An incremental increase in prenatal screening from the base case of 57% coverage to 95% coverage was associated with 106 (95% CI: 101, 111 CS cases averted per 100,000 live births (58% decrease. The policy strategies laid out in the national plan led to an outcome that fell short of the target, while a four-pronged comprehensive syphilis control strategy consisting of increased prenatal screening coverage, increased treatment completion, earlier prenatal screening, and improved syphilis test characteristics was associated with 157 (95% CI: 154, 160 CS cases averted per 100,000 live births (85% decrease.The Chinese national plan provides a strong foundation for syphilis control, but more comprehensive measures that include earlier and more

    Syphilis is the sexually transmitted disease caused by Treponema pallidum, a pathogen highly adapted to the human host. As a multistage disease, syphilis presents distinct clinical manifestations that pose different implications for diagnosis. Nevertheless, the inherent factors leading to diverse disease progressions are still unknown. We aimed to assess the association between treponemal loads and dissimilar disease outcomes, to better understand syphilis. We retrospectively analyzed 309 DNA samples distinct anatomic sites associated with particular syphilis manifestations. All samples had previously tested positive by a PCR-based diagnostic kit. An absolute quantitative real-time PCR procedure was used to precisely quantify the number of treponemal and human cells to determine T. pallidum loads in each sample. In general, lesion exudates presented the highest T. pallidum loads in contrast with blood-derived samples. Within the latter, a higher dispersion of T. pallidum quantities was observed for secondary syphilis. T. pallidum was detected in substantial amounts in 37 samples of seronegative individuals and in 13 cases considered as syphilis-treated. No association was found between treponemal loads and serological results or HIV status. This study suggests a scenario where syphilis may be characterized by: i) heterogeneous and high treponemal loads in primary syphilis, regardless of the anatomic site, reflecting dissimilar duration of chancres development and resolution; ii) high dispersion of bacterial concentrations in secondary syphilis, potentially suggesting replication capability of T. pallidum while in the bloodstream; and iii) bacterial evasiveness, either to the host immune system or antibiotic treatment, while remaining hidden in privileged niches. This work highlights the importance of using molecular approaches to study uncultivable human pathogens, such as T. pallidum, in the infection process. Copyright © 2017 Elsevier Ltd. All rights

    To assess overall adherence to Centers for Disease Control and Prevention and American College of Obstetrics and Gynecology recommended guidelines for syphilis testing among women who delivered a stillbirth and compare it with other tests recommended for stillbirth evaluation. We used MarketScan claims data with 40 million commercially insured and 8 million Medicaid enrollees annually to estimate prenatal care and follow-up testing among women who had stillbirths between January 1, 2013, and December 24, 2013. Stillbirth was identified if women had any International Classification of Disease, Ninth Revision codes related to a stillbirth outcome. Among women with stillbirths, we estimated the proportions of women who received prenatal care and prenatal syphilis testing within 280 days before stillbirth, and testing at the time of stillbirth (syphilis testing, complete blood count, placental examination and autopsy) using Physician's Current Procedural Terminology codes. We identified 3672 Medicaid-insured women and 6023 commercially insured women with stillbirths in 2013. Approximately, 61.7% of Medicaid-insured women and 66.0% of commercially insured women had claims data indicating prenatal syphilis testing. At the time of stillbirth, Medicaid-insured and commercially insured women had similar rates of syphilis testing (6.5% vs 9.3%), placental examination (61.6% vs 57.8%), and complete blood count (31.9% vs 37.6%). Autopsies were too infrequent to be reported. Approximately, 34.6% of Medicaid-insured women and 29.7% of commercially insured women had no syphilis testing either prenatally or at the time of stillbirth. Syphilis testing among women after stillbirth was less than 10%, illustrating limited adherence to Centers for Disease Control and Prevention and American College of Obstetrics and Gynecology recommendations. Such low prenatal and delivery syphilis testing rates may impact the number of stillbirth cases identified as congenital syphilis cases and

    Syphilis has been known to increase the risk of acquiring or transmitting HIV infection. Epidemiologic studies showed that HIV transmission is 3-5 times higher in people with syphilis.Hence, in this current study, the factors associated with syphilis-seropositive and HIV infection were evaluated.This study used cross-sectional study. This study included inmates at Lubuk Pakam prison in November 2016. After interviewing participants’ demographics and risk behaviors, blood samples were obtained to be tested for HIV and syphilis, using the Rapid Test tool of HIV 3 methods and One STEP Syphilis Anti TP-Test. A total number of 1,114 inmates were included in this study, consisted of 1,081 male (97%) and 33female (3%). Ten inmates were HIV-positive (0.9%), whereas 70 inmates were syphilis-seropositive (6.3%).Based on multivariate-analyses, high-risk sexual behaviors associated with the increased risk of syphilis-seropositive of up to 8.31 times (p=0.002). HIV status also portrayed higher risk of syphilis-seropositive compared to non-HIV participants (3.98 fold, p=0.019). In HIV incidence, found that high-risk sexual behaviors also significantly increased the risk of HIV (7.69 fold, p=0.003). Syphilis-seropositive was also highly associated with HIV risk (5.09 fold, p=0.019).Syphilis and HIV showed a close association with several shared contributing factors.

    2014-01-01

    Background. 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. Methods. 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. Results. 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. Conclusions. 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.

    The resurgence of syphilis in recent years has become a serious threat to the public health worldwide, and the serological detection of specific antibodies against Treponema pallidum (TP) remains the most reliable method for laboratory diagnosis of syphilis. The performance of the Elecsys ® Syphilis assay, a brand new electrochemiluminescene immunoassay (ECLIA), was assessed by large amounts of samples in this study. In comparison with InTec assay, the Elecsys ® Syphilis assay was evaluated in 146 preselected samples from patients with syphilis, 1803 clinical routine samples, and 175 preselected samples from specific populations with reportedly increased rates of false-positive syphilis test results. Discrepancy samples must be investigated by Mikrogen Syphilis recomline assay. There was an overall agreement of 99.58% between two assays (Kappa = 0.975). The sensitivity and specificity of the Elecsys ® Syphilis assay were 100.0% (95% CI, 96.8-100.0%) and 99.8% (95% CI, 99.5-100.0%), respectively. The Elecsys syphilis assay displays better sensitivity (100%), specificity (99.8%), PPV (98.7%), and NPV (100%) in 2124 samples enrolled, compared with the InTec assay. Considering the excellent ease of use and automation, high throughput, and its superior sensitivity, especially in primary syphilis, the Elecsys ® Syphilis assay could represent an outstanding choice for screening of syphilis in high-volume laboratories. However, more attention was still needed, or the results must be confirmed by other treponemal immunoassays. The new Elecsys ® Syphilis assay is applied to patients with malignant neoplasm or HIV infection. © 2016 Wiley Periodicals, Inc.

    Few men are tested for syphilis or human immunodeficiency virus (HIV) during their partner's pregnancy, a high-risk period for HIV and syphilis transmission. Offering home-based rapid testing of syphilis to couples during pregnancy can support prevention efforts to reduce transmission of sexually transmitted diseases and adverse pregnancy outcomes. We assessed men's uptake of paired (separate tests, single blood draw) point-of-care syphilis and HIV tests within a randomized controlled trial of pregnant women who received clinic or home partner HIV testing. We evaluated acceptance of paired HIV-syphilis testing during pregnancy or at 6 months postpartum, and evaluated whether addition of syphilis testing affected the uptake of HIV testing among men. Of 601 women, we were unable to meet 101 male partners, and 180 tested before syphilis tests were available. Paired syphilis and HIV testing was offered at home to 80 men during pregnancy and to 230 men postpartum. For syphilis, 93% of men agreed to test during pregnancy and 98% agreed postpartum. For paired syphilis and HIV testing, 91% of men tested for both during pregnancy and 96% tested postpartum. Before syphilis test introduction, 96% of men accepted HIV testing, compared with 95% of men who accepted HIV testing when paired testing was offered. Uptake of syphilis and HIV testing was high among male partners offered couple testing at home. Introducing syphilis testing did not adversely affect HIV testing among men. Point-of-care diagnostics outside facilities can increase testing of male partners who rarely accompany women to antenatal clinics.

    Objectives. After syphilis outbreaks were reported at 3 Alabama State men's prisons in early 1999, we conducted an investigation to evaluate risk factors for syphilis infection and describe patterns of syphilis transmission. Methods. We reviewed medical, patient interview, and prison transfer records and documented sexual networks. Presumptive source cases were identified. Odds of exposure to unscreened jail populations and transfer from other prisons were calculated for case patients at 1 prison. Results. Thirty-nine case patients with early syphilis were identified from 3 prisons. Recent jail exposure (odds ratio [OR] = 8.0, 95% confidence interval [CI] = 0.3, 158.7, P = .14) and prison transfer (OR = 32.0, 95% CI = 1.6, 1668.1, P prisons included mixing of prisoners with unscreened jail populations, transfer of infected inmates between prisons, and multiple concurrent sexual partnerships. Reducing sexual transmission of disease in correctional settings is a public health priority and will require innovative prevention strategies. PMID:11499107

    Despite the new World Health Organization data remind us how syphilis is a disease which affects both sexes equally, this pathology has always been mainly considered a male disease. While several famous men are known to be affected by syphilis, there are very few women affected by this pathology of which we have historical records. Through the lives of Mary Todd Lincoln, Catherine of Aragon, Karen Blixen and Florence Foster Jenkins, this article would like to grant dignity to all the women who contracted syphilis in the wrong historical era where, for a woman, admitting to contracting it was shameful. Through the important women who lived their lives fighting against this disease and its complications, we would like to pay tribute to all those women who still today, in an era of antibiotics and where syphilis is a treatable pathology, they cannot be cured because they are both geographically and socially disadvantaged.

    Full Text Available We report the case of a 44 year-old female, who presented a long-lasting, clinically atypical, secondary syphilis ("malignant syphilis" in the right foot, which started six months before medical evaluation. The patient had a serological diagnosis of HTLV-I infection and syphilis two years before the onset of the skin lesions, following a blood donation. As she believed she was allergic to penicillin, she initially received sulfamethoxazole + trimethoprim, without any improvement of the clinical picture. After failure of this first treatment regimen, she was given penicillin, which promoted complete healing of the lesion. We found evidence that infection by HTLV-I is capable of modifying the clinical course of secondary syphilis.

    This paper is aimed to discuss the involvement of delayed radiation effects of A-bomb exposure in cardiovascular diseases. First, the relationship between radiation and cardiovascular diseases is reviewed in the literature. Animal experiments have confirmed the relationship between ionizing radiation and vascular lesions. There are many reports which describe ischemic heart disease, cervical and cerebrovascular diseases, and peripheral disease occurring after radiation therapy. The previous A-bomb survivor cohort studies, i.e., the RERF Life Span Study and Adult Health Study, have dealt with the mortality rate from cardiovascular diseases, the prevalence or incidence of cardiovascular diseases, pathological findings, clinical observation of arteriosclerosis, ECG abnormality, blood pressure abnormality, and cardiac function. The following findings have been suggested: (1) A-bomb exposure is likely to be involved in the mortality rate and incidence of ischemic heart disease and cerebrovascular diseases; (2) similarly, the involvement of A-bomb exposure is considered in the prevalence of the arch of aorta; (3) ECG abnormality corresponding to ischemic heart disease may reflect the involvement of A-bomb exposure. To confirm the above findings, further studies are required on the basis of more accurate information and the appropriate number of cohort samples. Little evidence has been presented for the correlation between A-bomb exposure and both rheumatic heart disease and congenital heart disease. (N.K.) 88 refs

    The WHO called for the elimination of maternal-to-child transmission (MTCT) of HIV and syphilis, a harmonised approach for the improvement of health outcomes for mothers and children. Testing early in pregnancy, treating seropositive pregnant women and preventing syphilis reinfection can prevent MTCT of HIV and syphilis. We assessed the health and economic outcomes of a dual testing strategy in a simulated cohort of 100 000 antenatal care patients in Malawi. We compared four screening algorithms: (1) HIV rapid test only, (2) dual HIV and syphilis rapid tests, (3) single rapid tests for HIV and syphilis and (4) HIV rapid and syphilis laboratory tests. We calculated the expected number of adverse pregnancy outcomes, the expected costs and the expected newborn disability-adjusted life years (DALYs) for each screening algorithm. The estimated costs and DALYs for each screening algorithm were assessed from a societal perspective using Markov progression models. Additionally, we conducted a Monte Carlo multiway sensitivity analysis, allowing for ranges of inputs. Our cohort decision model predicted the lowest number of adverse pregnancy outcomes in the dual HIV and syphilis rapid test strategy. Additionally, from the societal perspective, the costs of prevention and care using a dual HIV and syphilis rapid testing strategy was both the least costly ($226.92 per pregnancy) and resulted in the fewest DALYs (116 639) per 100 000 pregnancies. In the Monte Carlo simulation the dual HIV and syphilis algorithm was always cost saving and almost always reduced DALYs compared with HIV testing alone. The results of the cost-effectiveness analysis showed that a dual HIV and syphilis test was cost saving compared with all other screening strategies. Updating existing prevention of mother-to-child HIV transmission programmes in Malawi and similar countries to include dual rapid testing for HIV and syphilis is likely to be advantageous.

    The continued occurrence of congenital syphilis is an indictment of the inadequate antenatal care services and poor quality of programmes to control sexually transmitted infections. More than 1 million infants are born with congenital syphilis each year. Despite national policies on antenatal testing and the widespread use of antenatal services, syphilis screening is still implemented only sporadically in many countries, leaving the disease undetected and untreated among many pregnant women. The weak organization of services and the costs of screening are the principal obstacles facing programmes. Decentralization of antenatal syphilis screening programmes, on-site testing and immediate treatment can reduce the number of cases of congenital syphilis. Antenatal syphilis screening and treatment programmes are as cost effective as many existing public health programmes, e.g. measles immunization. Diagnosis of congenital syphilis is problematic since more than half of all infants are asymptomatic, and signs in symptomatic infants may be subtle and nonspecific. Newer diagnostic tests such as enzyme immunoassays, polymerase chain reaction and immunoblotting have made diagnosis more sensitive and specific but are largely unavailable in the settings where they are most needed. Guidelines developed for better-resourced settings are conservative and err on the side of overtreatment. They are difficult to implement in, or inappropriate for, poorly-resourced settings because of the lack of investigative ability and the pressure on health facilities to discharge infants early. This paper offers recommendations for treating infants, including an approach based solely on maternal serological status and clinical signs of syphilis in the infant. PMID:15356934

    Given that syphilis is associated with HIV infection among people who inject drugs (PWID), we examined syphilis incidence among PWID in Tijuana, Mexico. From 2006 to 2007, 940 PWID (142 women and 798 men) were recruited via respondent-driven sampling and followed for 18 months. At semi-annual visits, participants were tested for syphilis and completed surveys, which collected information on socio-demographics, sexual behaviours, substance use and injection behaviours. Poisson regression was used to estimate syphilis incidence rates (IRs), incidence rate ratios (IRRs) and 95% confidence intervals (CIs). Twenty-one participants acquired syphilis during follow-up (IR = 1.57 per 100 person-years, 95% CI: 1.02-2.41). In a multivariate analysis, syphilis incidence was higher among women (IRR = 3.90, 95% CI: 1.37-11.09), HIV-positive participants (IRR = 4.60, 95% CI: 1.58-13.39) and those who reported ever exchanging sex for drugs, money, or other goods (IRR = 2.74, 95% CI: 0.97-7.76), while syphilis incidence was lower among those living in Tijuana for a longer duration (IRR = 0.95 per year, 95% CI: 0.91-1.00) and those reporting at least daily injection drug use (past 6 months) (IRR = 0.22, 95% CI: 0.09-0.54). Our findings suggest interventions that address the destabilising conditions associated with migration and integrate sexual and drug-related risk reduction strategies may help reduce syphilis incidence among PWID along the Mexico-US border. © The Author(s) 2015.

    Sexually transmitted diseases are a significant public health problem. Within the Madrid Autonomous Region, the districts with the highest syphilis and gonorrhea incidences are part of the same Public Health Service (Servicio de Salud Pública del Área 7, SSPA 7). The objective of this study was to identify, by spatial analysis, clusters of syphilis and gonorrhea infections in this SSPA in Madrid. All confirmed syphilis and gonorrhea cases registered in SSPA 7 in Madrid were selected. Moran's I was calculated in order to identify the existence of spatial autocorrelation and a cluster analysis was performed. Clusters and cumulative incidences (CI) per health zone were mapped. The district with most cases was Centro (CI: 67.5 and 160.7 per 100.000 inhabitants for syphilis and gonorrhea, respectively) with the highest CI (120.0 and 322.6 per 100.000 inhabitants) in the Justicia health zone.91.6% of all syphilis cases and 89.6% of gonorrhea cases were among men who have sex with men (MSM). Moran's I was 0.54 and 0.55 (p=0.001) for syphilis and gonorrhea, respectively. For syphilis, a cluster was identified including the six health zones of the Centro district, with a relative risk (RR)of 6.66 (p=0.001). For gonorrhea, a cluster was found including the Centro district, three health zones of the Chamberí district and one of Latina (RR 5.05; p=0.001). Centro was the district with most cases of syphilis and gonorrhea and the most affected population were MSM. For both infections, clusters were found with an important overlap. By identifying the most vulnerable health zones and populations, these results can help to design public health measures for preventing sexually transmitted diseases.

    The treatment failure and reinfection rates among syphilis patients are high, and relevant studies in China are limited. The aim of this study was to detect the rates of treatment failure and reinfection after syphilis treatment and to explore the potential associated factors. We conducted a longitudinal cohort study in a sexually transmitted disease clinic, the Department of Dermatology and Venereology in Nanshan Center for Chronic Disease Control. Serological testing was performed at baseline and throughout the 2-year follow-up for syphilis patients. To identify potential predictors of treatment outcomes, multivariate logistics analyses were utilized to compare the demographic and clinical characteristics of patients with serological failure/reinfection to those with serological cure/serofast. From June 2011 to June 2016, a total of 1133 patients were screened for syphilis. Among the 770 patients who completed the 2-year follow-up, 510 first-diagnosed patients were included in the final analysis. Multivariate logistics analysis revealed the stage of syphilis (secondary syphilis VS. primary syphilis: adjusted odds ratio, 3.50; 95% confidence interval, 1.11-15.47; p = 0.04), HIV status (positive VS. negative: adjusted odds ratio, 3.06; 95% confidence interval, 1.15-8.04; p = 0.02) and frequency of condom use (always use VS. never use: adjusted odds ratio, 0.28; 95% confidence interval 0.08-0.75; p = 0.02) were significantly associated with the serological outcome. The clinical implications of our findings suggest that it is very important to perform regular clinical and serologic evaluations after treatment. Health counseling and safety education on sex activity should be intensified among HIV-infected patients and secondary syphilis patients after treatment.

Herein we describe a cohort of 57 patients (age 18-68 years with secondary syphilis (SS identified through a network of public sector primary health care providers in Cali, Colombia. To be eligible for participation, study subjects were required to have cutaneous lesions consistent with SS, a reactive Rapid Plasma Reagin test (RPR-titer > or = 1 : 4, and a confirmatory treponemal test (Fluorescent Treponemal Antibody Absorption test- FTA-ABS. Most subjects enrolled were women (64.9%, predominantly Afro-Colombian (38.6% or mestizo (56.1%, and all were of low socio-economic status. Three (5.3% subjects were newly diagnosed with HIV infection at study entry. The duration of signs and symptoms in most patients (53.6% was less than 30 days; however, some patients reported being symptomatic for several months (range 5-240 days.

    1985-01-01

    The syphilis bacterium, Treponema pallidum, parasitizes host cells through recognition of fibronectin (Fn) on cell surfaces. The active site of the Fn molecule has been identified as a four-amino acid sequence, arg-gly-asp-ser (RGDS), located on each monomer of the cell-binding domain. The synthetic heptapeptide gly-arg-gly-asp-ser-pro-cys (GRGDSPC), with the active site sequence RGDS, specifically competed with 125 I-labeled cell-binding domain acquisition by T. pallidum. Additionally, the same heptapeptide with the RGDS sequence diminished treponemal attachment to HEp-2 and HT1080 cell monolayers. Related heptapeptides altered in one key amino acid within the RGDS sequence failed to inhibit Fn cell-binding domain acquisition or parasitism of host cells by T. pallidum. The data support the view that T. pallidum cytadherence of host cells is through recognition of the RGDS sequence also important for eukaryotic cell-Fn binding

    Pavia, Charles S.; Folds, James D.; Baseman, Joel B.

    1978-01-01

    Evidence is presented which reinforces the complexity of the host-parasite interaction during the course of syphilis. Infection with Treponema pallidum evokes a complicated antibody response and an assortment of cell-mediated immune reactions in the host. It appears that humoral immunity plays a minor role towards the complete elimination of syphilitic infection while the cellular limb of the immune response may be an important host defence mechanism. Information now available indicates that a state of anergy, or immunosuppression, exists in the early stages of human and experimental rabbit syphilis based upon negative skin reactions to T. pallidum antigen(s), the abnormal histological appearance of lymphoid organs, and impaired in vitro lymphocyte reactivity. It is also evident that in the later stages of the disease cellular immunity becomes activated as delayed type skin reactions can normally be elicited in tertiary syphilitics and lymphocyte behaviour in cell culture appears normal. Several mechanisms have been invoked to explain the delay in an effective immune response against syphilitic infection and the duration of the disease: (1) a capsule-like substance on the outer surface of virulant T. pallidum may act as a barrier against treponemicidal antibody; (2) this material and other biological properties of virulent treponemes could enable spirochaetes to escape being engulfed by macrophages and other phagocytic cells; (3) antigenic competition among different treponemal antigens causing partial tolerance; (4) T. pallidum infection may bring about the elaboration of immunosuppressive substances of host or treponemal origin which inhibit the proper function of lymphocytes, macrophages, and other cell types.

    2016-01-01

    Introduction Syphilis and human immunodeficiency virus (HIV) co-infection disproportionately affects men who have sex with men (MSM), and the rate of co-infection has been increasing over the last decade. HIV and syphilis co-infection is particularly challenging because the infections interact synergistically thereby increasing the risk of acquisition and transmission as well as accelerating disease progression. Areas Covered This paper reviews and summarizes the epidemiology, pathogenesis, diagnosis, clinical management and prevention of HIV and syphilis co-infection among MSM. Expert Commentary Research does not support a different syphilis treatment for co-infected individuals; however, co-infection may warrant a recommendation for antiretroviral therapy. In order to reverse the epidemic of syphilis and HIV co-infection, there needs to be greater awareness, improved cultural sensitivity among health care providers, improved access to preventative services and increased screening for syphilis and HIV.

Patients with early forms use more primitive mechanisms (denial, substitution. Conclusion. The obtained data may be useful in the choice of methods of psychotherapy, the formation of patients more realistic (ADAP-tive installations for the treatment, restoration of family and other social relations, the prevention of distress and improving the quality of life of patients.

    This paper describes the sex work characteristics and factors associated with syphilis among female sex workers (FSWs) in Dimapur district of high HIV prevalence Indian state, Nagaland. The study recruited 426 FSWs in 2006 using respondent-driven sampling. The prevalence of syphilis was 21.1% and HIV prevalence was 11.7%. Approximately half were under 25 years of age. Clients were solicited mainly in public places (32.7%), while hotels/lodges/rented rooms were the most common places of entertainment (57.2%). Condom use during the last sex was 36.5% with occasional and 27% with regular clients. Being married, being widowed/divorced/separated, being illiterate or having a history of drug use increased the likelihood of syphilis infection. Entertaining clients in bars/booze joints decreased the probability of syphilis. FSWs who moved between soliciting in public places or bars/booze joints and then entertaining in hotels/lodges/rented rooms had a higher vulnerability to syphilis. In summary, we found that the vulnerability to syphilis among mostly young FSWs in Dimapur varied according to their sex work characteristics, marital and educational status and drug use habits. They may be more vulnerable to HIV and sexually transmitted infections (HIV/STIs) due to the low rate of condom use. The findings have direct implications for HIV/STI prevention programmes in Northeast India.

    to evaluate the prevalence of maternal syphilis at delivery and neonatal syphilis infection in an Italian urban area, in connection with the increased flow of immigration. A prospective surveillance study was carried out in Bologna, Italy, from November 2000 to March 2006. All pregnant women were screened for syphilis at delivery. Infants born to seropositive mothers were enrolled in a prospective follow-up. During the study period 19,205 women gave birth to 19,548 infants. A total of 85 women were seropositive for syphilis at delivery. The overall syphilis seroprevalence in pregnant women was 0.44%, but it was 4.3% in women from eastern Europe and 5.8% in women from Central-South America. Ten women were first found positive at delivery, as they did not receive any prenatal care. Nine of these were from eastern Europe. All their infants were asymptomatic, but six had both reactive immunoglobulin (Ig)M western blot and rapid plasma reagin tests and were considered prenatally infected. Three of six were preterm (gestational age eastern Europe. Although it is asymptomatic, it could cause premature delivery. Therefore, it is necessary to perform serological tests during the third trimester in mothers coming from endemic areas to adequately treat syphilis in pregnancy and prevent congenital infection. If the mother's test results are not available at delivery, it is necessary to investigate the newborn, especially if it is born prematurely.

    Abstract:
    Background: This work aims to analyze trends of syphilis infections in the Piedmont Region (Italy between 2002 and 2008, and to evaluate risk factors for infection. Methods: Syphilis trends were described according to socio-demographic characteristics, sexual behavior, condom use, number of partners and HIV infection. Independent risk factors for syphilis among men having sex with men (MSM, men having sex with women (MSW, and women were identified through logistic regression comparing cases with 12,773 negative patients. Results: Between 2002 and 2008, 1,046 cases of syphilis were diagnosed, with peaks in 2004 and 2007. The risk of a syphilis diagnosis was independently associated with being older than 24, having a low education level, homosexual behavior, HIV self-reported infection (for MSM and MSW, number of partners (for MSW and women and non- consistent condom use (for women. Conclusions: Recent outbreaks suggest that the attention to syphilis can’t be lowered. Screening, treatment of cases and notification of partners should be reinforced and integrated with sexual health education and counselling in high-risk environments. Surveillance data must be continuously collected.

    Peripartal transmission of human immunodeficiency virus (HIV) and Treponema pallidum, the causative agent of syphilis, leads to severe consequences for newborns. Preventive measures require awareness of the maternal infection. Although HIV and syphilis testing in Madagascar could be theoretically carried out within the framework of the national pregnancy follow-up scheme, the required test kits are rarely available at peripheral health centres. In this study, we screened blood samples of pregnant Madagascan women for HIV and syphilis seroprevalence to estimate the demand for systemic screening in pregnancy. Retrospective anonymous serological analysis for HIV and syphilis was performed in plasma samples from 1232 pregnant women that were taken between May and July 2010 in Ambositra, Ifanadiana, Manakara, Mananjary, Moramanga and Tsiroanomandidy (Madagascar) during pregnancy follow-up. Screening was based on Treponema pallidum haemagglutination tests for syphilis and rapid tests for HIV, with confirmation of positive screening results on line assays. Out of 1232 pregnant women, none were seropositive for HIV and 37 (3%) were seropositive for Treponema pallidum. Our findings are in line with previous studies that describe considerable syphilis prevalence in the rural Madagascan population. The results suggest a need for screening to prevent peripartal Treponema pallidum transmission, while HIV is still rare. If they are known, Treponema pallidum infections can be easily, safely and inexpensively treated even in pregnancy to reduce the risk of transmission. © 2012 Blackwell Publishing Ltd.

    The resurgence of syphilis in recent years has become a serious threat to public health worldwide, and the serological detection of specific antibodies against Treponema pallidum remains the most reliable method for laboratory diagnosis of syphilis. This study examined the performance of the recently launched HISCL anti-Treponema pallidum (anti-TP) assay as a screening test for syphilis in a high-volume laboratory. The HISCL anti-TP assay was tested in 300 preselected syphilis-positive samples, 704 fresh syphilis-negative samples, 48 preselected potentially interfering samples, and 30 "borderline" samples and was compared head to head with the commercially available Lumipulse G TP-N. In this study, the HISCL anti-TP assay was in perfect agreement with the applied testing algorithms with an overall agreement of 100%, comparable to that of Lumipulse G TP-N (99.63%). The sensitivity and specificity of the HISCL anti-TP assay were 100% (95% confidence interval [CI], 98.42% to 100%) and 100% (95% CI, 99.37% to 100%), respectively. Considering the excellent ease of use and automation, high throughput, and its favorable sensitivity and specificity, the HISCL anti-TP assay may represent a new choice for syphilis screening in high-volume laboratories.

    After reaching an all time low in 2000, the rate of syphilis in the United States has been steadily increasing. Parallel benchmarking of the disease's mortality burden has not been undertaken. Using ICD-10 classification, all syphilis-related deaths in the national Multiple Cause of Death dataset were examined for the period 2000-2014. Descriptive statistics and age-adjusted mortality rates were generated. Poisson regression was performed to analyze trends over time. A matched case-control analysis was conducted to assess the associations between syphilis-related deaths and comorbid conditions listed in the death records. A total of 1,829 deaths were attributed to syphilis; 32% (n = 593) identified syphilis as the underlying cause of death. Most decedents were men (60%) and either black (48%) or white (39%). Decedents aged ≥85 years had the highest average mortality rate (0.47 per 100,000 population; 95% confidence interval [CI], 0.42-0.52). For the sampled period, the average annual decline in mortality was -2.90% (95% CI, -3.93% to -1.87%). However, the average annual percent change varied across subgroups of interest. Declines in U.S. syphilis mortality suggest early detection and improved treatment access likely helped attenuate disease progression; however, increases in the disease rate since 2000 may be offsetting the impact of these advancements.

    Many health agencies now recommend routine HIV and syphilis testing for pregnant women and most-at-risk populations such as men who have sex with men. With the increased availability of highly sensitive, low cost rapid point-of-care tests, the ability to meet those recommendations has increased, granting wider access to quick and accurate diagnoses. Using blood specimens collected from a Baltimore City Health Department (BCHD) sexually transmitted infection clinic, we evaluated the SD Bioline HIV/Syphilis Duo, a rapid test that simultaneously detects antibodies to HIV and syphilis and has the potential to further benefit clinics and patients by reducing costs, testing complexity, and patient wait times. SD DUO HIV sensitivity and specificity, when compared to BCHD results, were 91.7 and 99.5%, respectively. SD DUO syphilis sensitivity and specificity, when compared to rapid plasma reagin, were 85.7 and 96.8%, respectively, and 69.7 and 99.7%, respectively, when compared to Treponema pallidum particle agglutination (TPPA). SD DUO syphilis sensitivity and specificity, when compared to a traditional screening algorithm, improved to 92.3 and 100%, respectively, and improved to 72.9 and 99.7%, respectively, when compared to a reverse screening algorithm. The HIV component of the SD DUO performed moderately well. However, results for the SD DUO syphilis component, when compared to TPPA, support the need for further testing and assessment.

    To observe any changes in stria vascularis and cochlear hair cells in patients with syphilis. We examined 13 human temporal bone samples from 8 patients with syphilis (our syphilis group), as well as 12 histopathologically normal samples from 9 age-matched patients without syphilis (our control group). We compared, between the two groups, the mean area of the stria vascularis (measured with conventional light microscopy connected to a personal computer) and the mean percentage of cochlear hair cell loss (obtained from cytocochleograms). In our syphilis group, only 1 (7.7%) of the 13 samples had precipitate in the endolymphatic or perilymphatic spaces; 8 (61.5%) of the samples revealed the presence of endolymphatic hydrops (4 cochlear, 4 saccular). The mean area of the stria vascularis did not significantly differ, in any turn of the cochlea, between the 2 groups (P>0.1). However, we did find significant differences between the 2 groups in the mean percentage of outer hair cells in the apical turn (Psyphilis group, we observed either complete loss of the organ of Corti or a flattened organ of Corti without any cells in addition to the absence of both outer and inner hair cells. In this study, syphilis led either to complete loss of the organ of Corti or to significant loss of cochlear hair cells, in addition to cochleosaccular hydrops. But the area of the stria vascularis did not change. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Syphilis infection in pregnancy is known to cause a number of severe adverse pregnancy outcomes, including second-trimester miscarriage, stillbirth, very pre-term delivery and neonatal death, in addition to congenital syphilis. A retrospective review of women with positive syphilis serology and a pregnancy outcome between 2005 and 2012 in Leeds, UK, was performed. In all, 57 cases of positive syphilis serology in pregnancy were identified: 24 with untreated syphilis treated in the current pregnancy (Group 1); seven with reported but unconfirmed prior treatment who were retreated (Group 2); and 26 adequately treated prior to pregnancy (Group 3). The rate of severe adverse pregnancy outcomes in Group 1 at 21% was significantly higher than the 0% outcome of Group 3 (p = 0.02). The severe adverse pregnancy outcomes were two second-trimester miscarriages, two pre-term births at 25 and 28 weeks and one stillbirth at 32 weeks. There were no cases of term congenital syphilis or term neonatal death, but we observed high rates of other adverse pregnancy outcomes despite treatment during pregnancy. Rapid referral for treatment is needed before 18 weeks in order to minimise adverse pregnancy outcomes. © The Author(s) 2016.

    Full Text Available Background. Syphilis research has neglected the prevalence of the disease among psychiatric patients, and traditional syphilis screening has been reported as inadequate. Objectives. (i To assess the syphilis prevalence among psychiatric patients; (ii to compare psychiatric diagnoses of syphilis-infected and -uninfected patients; (iii to assess self-reported high-risk sexual behaviour; (iv to establish syphilis/HIV co-morbidity; and (v to investigate the performance of the rapid plasma reagin (RPR test in syphilis screening, compared with the Treponema pallidum haemagglutination (TPHA test. Methods. Psychiatric inpatients at Weskoppies Hospital, Pretoria, who consented to participate in the study (N=195 were categorised according to gender and length of admission (long-term or recent. Non-treponemal RPR, confirmatory TPHA, HIV-rapid and HIV enzyme-linked immunosorbent assay (ELISA tests were performed. A reactive TPHA test was used to diagnose syphilis. Results. The estimated prevalence of syphilis was 11.7%. There was no significant association between TPHA sero-positivity and primary psychiatric diagnosis or self-reported high-risk sexual behaviour. Significant co-morbidity existed between syphilis and HIV (p=0.012. Compared with the TPHA test, the RPR test performed poorly, identifying only 2/23 patients who had a sero-positive TPHA test (8.7% sensitivity and 100% specificity. Conclusions. The prevalence of syphilis was higher than anticipated, supporting the need for routine testing. The significant co-morbidity and alarming prevalence of HIV and syphilis warrant testing for both conditions in all psychiatric admissions. Current syphilis screening with a single RPR test is inadequate; both RPR and TPHA tests should be performed.

    Little information is available on the rapid diagnostic testing for syphilis in Burkina Faso. The objectives of the study were (i) to assess the sensitivity and specificity of four on site rapid tests in comparison with Treponema pallidum haemagglutination assay (TPHA) as a gold standard and (ii) to evaluate the operational characteristics of those tests among health workers in a maternity unit. Four rapid syphilis tests commercially available in Burkina Faso were evaluated using archived serum samples and Treponema pallidum hemagglutination assay (TPHA) as the gold standard. Blood samples were collected between November 2011 and June 2012 from blood donors at the Regional Blood Transfusion Center of Ouagadougou. The sensitivity and specificity of the tests were calculated. Evaluation of operational characteristics such as clarity of pamphlet, complexity of technique, duration, was conducted in a first-level healthcare center with health workers in maternity unit. Alere DetermineTM Syphilis was the most sensitive of the four rapid syphilis tests evaluated. It was followed by SD Bioline Syphilis 3.0, Cypress Diagnostics Syphilis Quick test and Accu-Tell ® Rapid Anti-TP, which was the least sensitive. The four tests demonstrated a good diagnostic specificity for syphilis (95-98%), and healthcare workers found them easy to use. The study allowed confirming the good performance of three of four rapid syphilis tests in Burkina Faso. More research will be conducted to assess the feasibility of introducing selected rapid tests for syphilis in antenatal care services.

    Background: Syphilis, a sexually transmitted disease which seemed to have disappeared or had been controlled over the years, has now been re-emerged as a major public health problem in many communities. It can complicate the pregnancies with serious consequences. Appropriate treatment of pregnant women often prevents such complications. Aims: To study the frequency of syphilis in pregnant women attending a tertiary care public sector hospital, and see the positivity for HIV/AIDS among syphilis positive women. Patients and Methods: This cross sectional and interventional study was conducted among pregnant women attending Sir Ganga Ram hospital for antenatal care at PMRC Research Centre, Fatima Jinnah Medical College, Lahore. Blood samples from 2000 women were collected after taking consent. The blood was tested for syphilis by Treponema Pallidum Haemagglutination. History of the subjects for risks factors was also taken. Syphilis positive women were further screened for human immunodeficiency virus positivity. Results: The treponemal antibodies were detected in less than one percent (9) pregnant women. The highest positivity was observed among age group of 21-26 years. Women in third trimester were significantly more infected with syphilis. Risk factors included husband's history with frequent traveling and drug abuse. All husbands of syphilis positive women were also positive. All syphilis positive women and their husbands were negative for Human immunodeficiency virus /Acquired immune deficiency syndrome. Conclusions: Less than 1% of pregnant women were infected with syphilis, and most of the spouses of these positive women were either travelers or drug addicts.(author)

    Between 1999 and 2002, San Francisco experienced a sharp increase in early syphilis among gay and bisexual men. In response, the San Francisco Department of Public Health launched a social marketing campaign to increase testing for syphilis, and awareness and knowledge about syphilis among gay and bisexual men. A convenience sample of 244 gay and bisexual men (18-60 years of age) were surveyed to evaluate the effectiveness of the campaign. Respondents were interviewed to elicit unaided and aided awareness about the campaign, knowledge about syphilis, recent sexual behaviors, and syphilis testing behavior. After controlling for other potential confounders, unaided campaign awareness was a significant correlate of having a syphilis test in the last 6 months (odds ratio, 3.21; 95% confidence interval, 1.30-7.97) compared with no awareness of the campaign. A comparison of respondents aware of the campaign with those not aware also revealed significant increases in awareness and knowledge about syphilis. The Healthy Penis 2002 campaign achieved its primary objective of increasing syphilis testing, and awareness and knowledge about syphilis among gay and bisexual men in San Francisco.

    An unconfirmed positive treponemal enzyme immunoassay (enzyme immunoassay positive, Treponema pallidum particle agglutination negative and rapid plasma reagin negative) presents a clinical challenge to distinguish early syphilis infection from false-positive results. These cases are referred for syphilis line assay (INNO-LIA) and recalled for repeat syphilis serology. We performed a retrospective audit to establish the proportion of HIV-negative cases with unconfirmed positive enzyme immunoassay results, the proportion of these cases that received an INNO-LIA test and repeat syphilis serology testing and reviewed the clinical outcomes; 0.35% (80/22687) cases had an unconfirmed positive treponemal enzyme immunoassay result. Repeat syphilis serology was performed in 80% (64/80) cases, but no additional cases of syphilis were identified. Eighty-eight per cent (70/80) received an INNO-LIA test; 14% (5/37) unconfirmed enzyme immunoassay-positive cases with no prior history of syphilis were confirmed on INNO-LIA assay, supporting a diagnosis of latent syphilis. As a confirmatory treponemal test, the INNO-LIA assay may be more useful than repeat syphilis serological testing. © The Author(s) 2016.

    Background Congenital syphilis continues to be a preventable cause of global stillbirth and neonatal morbidity and mortality. Shortages of injectable penicillin, the only recommended treatment for pregnant women and infants with syphilis, have been reported by high-morbidity countries. We sought to estimate current and projected annual needs for benzathine penicillin in antenatal care settings for 30 high morbidity countries that account for approximately 33% of the global burden of congenital syphilis. Methods Proportions of antenatal care attendance, syphilis screening coverage in pregnancy, syphilis prevalence among pregnant women, and adverse pregnancy outcomes due to untreated maternal syphilis reported to WHO were applied to 2012 birth estimates for 30 high syphilis burden countries to estimate current and projected benzathine penicillin need for prevention of congenital syphilis. Results Using current antenatal care syphilis screening coverage and seroprevalence, we estimated the total number of women requiring treatment with at least one injection of 2.4 MU of benzathine penicillin in these 30 countries to be 351,016. Syphilis screening coverage at or above 95% for all 30 countries would increase the number of women requiring treatment with benzathine penicillin to 712,030. Based on WHO management guidelines, 351,016 doses of weight-based benzathine penicillin would also be needed for the live-born infants of mothers who test positive and are treated for syphilis in pregnancy. Assuming availability of penicillin and provision of treatment for all mothers diagnosed with syphilis, an estimated 95,938 adverse birth outcomes overall would be prevented including 37,822 stillbirths, 15,814 neonatal deaths, and 34,088 other congenital syphilis cases. Conclusion Penicillin need for maternal and infant syphilis treatment is high among this group of syphilis burdened countries. Initiatives to ensure a stable and adequate supply of benzathine penicillin for treatment

    Background Syphilis point-of-care tests may reduce morbidity and ongoing transmission by increasing the proportion of people rapidly treated. Syphilis stage and co-infection with HIV may influence test performance. We evaluated four commercially available syphilis point-of-care devices in a head-to-head comparison using sera from laboratories in Australia. Methods Point-of-care tests were evaluated using sera stored at Sydney and Melbourne laboratories. Sensitivity and specificity were calculated by standard methods, comparing point-of-care results to treponemal immunoassay (IA) reference test results. Additional analyses by clinical syphilis stage, HIV status, and non-treponemal antibody titre were performed. Non-overlapping 95% confidence intervals (CI) were considered statistically significant differences in estimates. Results In total 1203 specimens were tested (736 IA-reactive, 467 IA-nonreactive). Point-of-care test sensitivities were: Determine 97.3%(95%CI:95.8–98.3), Onsite 92.5%(90.3–94.3), DPP 89.8%(87.3–91.9) and Bioline 87.8%(85.1–90.0). Specificities were: Determine 96.4%(94.1–97.8), Onsite 92.5%(90.3–94.3), DPP 98.3%(96.5–99.2), and Bioline 98.5%(96.8–99.3). Sensitivity of the Determine test was 100% for primary and 100% for secondary syphilis. The three other tests had reduced sensitivity among primary (80.4–90.2%) compared to secondary syphilis (94.3–98.6%). No significant differences in sensitivity were observed by HIV status. Test sensitivities were significantly higher among high-RPR titre (RPR≥8) (range: 94.6–99.5%) than RPR non-reactive infections (range: 76.3–92.9%). Conclusions The Determine test had the highest sensitivity overall. All tests were most sensitive among high-RPR titre infections. Point-of-care tests have a role in syphilis control programs however in developed countries with established laboratory infrastructures, the lower sensitivities of some tests observed in primary syphilis suggest these would

    Malignant syphilis or lues maligna is a severe form of secondary syphilis that was commonly reported in the pre-antibiotic era, and has now reemerged with the advent of the human immunodeficiency virus (HIV) epidemic. However, the characteristic histopathological findings of malignant syphilis remain controversial. The aim of this case report was to clarify the clinical and histopathological findings of HIV-positive malignant secondary syphilis. A Japanese man in his forties complained of fever, skin lesions, headache, and myalgia without lymphadenopathy during the previous 4 weeks. The skin lesions manifested as erythematous, nonhealing, ulcerated papules scattered on his trunk, extremities, palm, and face. Although the skin lesions were suspected to be cutaneous T-cell lymphomas on histological analyses, they lacked T-cell receptor Jγ rearrangement; moreover, immunohistochemical analyses confirmed the presence of spirochetes. The patient was administered antibiotics and anti-retroviral therapy, which dramatically improved the symptoms. On the basis of these observations of the skin lesions, we finally diagnosed the patient with HIV-associated secondary syphilis that mimicked cutaneous T-cell lymphoma. The patient's systemic CD4+ lymphocyte count was very low, and the infiltrate was almost exclusively composed of CD8+ atypical lymphocytes; therefore, the condition was easily misdiagnosed as cutaneous lymphoma. Although the abundance of plasma cells is a good indicator of malignant syphilis on skin histological analyses, in some cases, the plasma cell count may be very low. Therefore, a diagnosis of malignant secondary syphilis should be considered before making a diagnosis of primary cutaneous peripheral T-cell lymphoma or lymphoma associated with HIV infection.

    The Jarisch-Herxheimer reaction (JHR) is a febrile inflammatory reaction that may occur in patients after treatment of syphilis. The overall rate is estimated to be 10-25% with broad variations over time. It appears to be related to factors like stage of the disease or reagin titres. In this study we aimed to describe the incidence of and risk factors including strain typing for JHR among patients with syphilis. From January through October 2015, 224 consecutive patients (82 of them with HIV) who were diagnosed with early syphilis were enrolled in this prospective observational study in a referral STI clinic in Barcelona. An appointment was offered to them after 10-14 days of treatment to inquire about the reaction with the use of a standardized form. T. pallidum molecular typing was made to detect a possible strain related to reaction. Overall, 28% of patients developed JHR. This varied from 56% in secondary, 37% in primary to 7% in early latent syphilis. The most frequent types of reaction were fever (57.5%) and worsening of the lesions (31%). The median time to development of JHR was 6 hours [IQR 4-10 hours] and lasted a median of 9 hours [IQR 4-24 hours]. The JHR was less probable in early latent compared to primary/secondary syphilis (P=0.04) and in patients treated with doxycycline compared to those treated with penicillin (P=0.01). No differences were seen regarding reagin titres or HIV status and no association with a specific strain was found. In this study, JHR occurred in a similar frequency as in other contemporary studies. Symptomatic syphilis and treatment with penicillin were associated with an increased risk of JHR, whereas the previous episode of syphilis was associated with a low risk of it. We could not find associations with specific strains of T. pallidum. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

    Full Text Available Sexually transmitted infections (STI have made a resurgence in many rapidly developing regions of southern China, but there is little understanding of the social changes that contribute to this spatial distribution of STI. This study examines county-level socio-demographic characteristics associated with syphilis and gonorrhea in Guangdong Province.This study uses linear regression and spatial lag regression to determine county-level (n = 97 socio-demographic characteristics associated with a greater burden of syphilis, gonorrhea, and a combined syphilis/gonorrhea index. Data were obtained from the 2005 China Population Census and published public health data. A range of socio-demographic variables including gross domestic product, the Gender Empowerment Measure, standard of living, education level, migrant population and employment are examined. Reported syphilis and gonorrhea cases are disproportionately clustered in the Pearl River Delta, the central region of Guangdong Province. A higher fraction of employed men among the adult population, higher fraction of divorced men among the adult population, and higher standard of living (based on water availability and people per room are significantly associated with higher STI cases across all three models. Gross domestic product and gender inequality measures are not significant predictors of reported STI in these models.Although many ecological studies of STIs have found poverty to be associated with higher reported STI, this analysis found a greater number of reported syphilis cases in counties with a higher standard of living. Spatially targeted syphilis screening measures in regions with a higher standard of living may facilitate successful control efforts. This analysis also reinforces the importance of changing male sexual behaviors as part of a comprehensive response to syphilis control in China.

    Data on syphilis seroprevalence among human immunodeficiency virus (HIV)/Acquired immunodeficiency syndrome (AIDS) patients are unavailable in Turkey although they have common transmission routes. Our study is oriented towards the assessment of the seroprevalence of syphilis and the related risk factors in the HIV/AIDS patients followed in our outpatient clinic. Newly diagnosed HIV/AIDS cases (n = 308) who attended our outpatient clinic between January 2006 and April 2013 were included in the study. Patient characteristics, medical history, physical examination findings, CD4+ T lymphocyte count, HIV RNA level, rapid plasma reagent (RPR) and Treponema pallidum hemagglutination (TPHA) test results were analyzed retrospectively. TPHA positivity was considered indicative of syphilis-causing T pallidum exposure. HIV infection was transmitted through heterosexual (n = 176) or homosexual (n =131) contact (266 male, 86.3%; age 38.3 ± 11.7 years; CD4+ T lymphocyte count, 330.6 ± 15.17/mm3). 50.7% of the patients attained only primary education. Out of the 245 cases, who were asked about the number of their sexual partners, 40 patients (26 women) lived in a monogamous relationship. Condom usage was not practiced (57.2%) or was only occasional (34.4% - particularly with their legal spouses and for contraception). Physical exam revealed no signs of syphilis or other STIs. TPHA (+/- RPR) positivity was determined in 40 patients (12.9%), indicating T pallidum exposure. All patients with positive syphilis serology were male (p= 0.0026). T pallidum exposure was determined in 21.3% of homosexual and 6.8% of heterosexual cases (p = 0.0003). Since sexual contact is the most common route of transmission for both infections, syphilis seroprevalence was relatively high in our HIV/AIDS patients. Male and homosexual HIV/AIDS patients constituted a group at the highest risk for syphilis.

    The aim of this study was to determine the prevalence of syphilis and toxoplasmosis infection in pregnant women in the Central African Republic who were and were not HIV-infected, in the framework of HIV surveillance. This case-control study included 270 HIV(+) and 217 HIV(-) pregnant women among 4 750 women who attended prenatal-care clinics throughout the Central African Republic from November 2011 through January 2012. Blood specimens were collected and serological evidence of HIV1/2 was analyzed by ELISA1 and ELISA2. The Toxoplasma gondii antibody was detected with the Toxo-Hai Fumouze(®) diagnostic kit. A VDRL test was performed to screen for syphilis in all study participants. Of the 434 samples tested, 33 (7.60%) were positive for syphilis: 21 (9.7%) among HIV(+) and 12 (5.5%) among HIV(-) women (p = 0.1031); 221 (50.90%) were positive for toxoplasmosis: 117 (53.9%) among HIV(+) and 104 (47.9%) among HIV(-) women (p = 0, 2119). Coinfection with HIV, syphilis, and toxoplasmosis was found in 6.00%. No association was found between coinfection and age, parity, and residence area. The rate of syphilis infection was very high in pregnant women living in rural areas (ORcrude = 4.37; 95% CI = 2,11, 9.05). This study showed a high prevalence of toxoplasmosis and syphilis in pregnant women in the Central African Republic, regardless of their HIV infection status. Sexually transmitted infections (STIs) are common in pregnant women living in rural areas. It may be appropriate to include routine serological screening tests to determine of toxoplasmosis, syphilis and HIV in pregnant women in this country.

    Syphilis has been reinstated on the list of notifiable diseases in Switzerland since 2006 and the active management of sexual partners is encouraged to avoid reinfection. However, contact tracing has yielded unsatisfactory results and the incidence of syphilis remains important, especially in high-risk populations. The aim of this study was to compare the proportions of notified sexual partners of patients diagnosed with syphilis by the laboratories of Geneva University Hospitals (HUG) with those diagnosed in private laboratories (non-HUG) and to assess the risk factors for no notification to sexual partners. All syphilis cases notified to the Office of the Surgeon General in Geneva (Switzerland) between 1 January 2011 and 31 December 2013 were analysed. The proportions of partner notification (PN) between HUG and non-HUG laboratories were compared by Chi square test and the main risk factors for no notification to sexual partners were assessed by binomial log-linear regression. Among a total of 720 notifications reported, 244 cases were diagnosed with contagious syphilis stages and 263 with non-contagious stages (i.e. successfully treated patients with or late latent cases). Overall, PN was higher among contagious than non-contagious cases (58.4% versus 31.0%; p = 0.030) and it was significantly higher in the non-HUG compared to the HUG group (75.9% versus 50.0%, respectively; p 45 years (RR 1.36; 95% CI: 1.05-1.76) and if the patient had received treatment for syphilis (RR 1.91; 95% CI: 1.38-2.66). Our results illustrate the difficulty of contact tracing in syphilis infection and the necessity to improve this crucial part of sexually transmitted infection management.

    National notifications for infectious syphilis in Australia have increased in recent years. Outside of sexual health clinics, junior clinicians seldom encounter this disease in its infectious stage (primary, secondary and early latent). With such a variable clinical presentation, textbook teaching is no substitute for real-life experience. The importance of accurate classification and staging of disease is relevant to the risk of transmission and determines treatment duration. In this article, the authors review the clinical presentation of syphilis over ten years in an urban sexual health clinic with a focus on the clinical presentation and diagnosis of infectious syphilis, in particular secondary syphilis, compared with that outlined in the Australian National Notifiable Diseases Surveillance System guidelines. This retrospective review of all patients diagnosed with syphilis at an urban sexual health clinic showed that between 2005 and 2015, 226 cases of syphilis were diagnosed. Documentation of impression of clinical staging of disease was present in 46% of the cases. Seventeen of these cases were recorded as secondary syphilis. The criteria used by clinicians to diagnose the secondary syphilis cases were consistent with criteria defined by the Australian National Notifiable Diseases Surveillance System. All cases of secondary syphilis had at least one cutaneous manifestation of disease. The demographic of the cohort of syphilis cases was consistent with that recorded in the literature. This review showed that the clinician's diagnosis of secondary syphilis in this service is consistent with the National Notifiable Diseases Surveillance System guidelines. Continuing education of junior medical staff is important to facilitate diagnosis and improve documentation of clinical staging, minimise disease transmission and ensure appropriate treatment. © The Author(s) 2016.

    We evaluated the performance of two immunoblot assays: the INNO-LIA Syphilis Score (LIA) and the MarDx T. pallidum IgG Marblot Test (TWB), as compared with that of the Murex ICE Syphilis enzyme immunoassay (EIA), the Serodia Treponema pallidum particle agglutination (TPPA) assay and the fluorescent treponemal antibody-absorption (FTA-abs) assay, for the serological diagnosis of syphilis using serum samples of 135 attendees of the social hygiene clinics of the Department of Health in Hong Kong newly diagnosed with syphilis and provided with clinical stages (39 in primary, 20 in secondary, 18 in early latent and 58 in latent of unknown duration) and of 43 normal healthy subjects between October and December 2004. The differences in the overall sensitivities of the LIA assay and the EIA/TPPA/FTA-abs assays were not statistically significant (P > 0.05) whereas the overall sensitivity of the TWB assay was significantly lower (P FTA-abs assays. The LIA assay had an overall sensitivity of 94.1% (95% CI 88.7-97.0%) whereas the TWB assay 65.2% (95% CI 56.8-72.7%). Both the LIA and the TWB assays have a specificity of 100%. When consensus results were derived from the most predominant results of the EIA, the TPPA and the FTA-abs assays, the LIA assay had a positive agreement with the consensus results of 98.5% (95% CI 94.5-99.6%) whereas the TWB assay 68.2% (95% CI 59.8-75.6%). Therefore, the LIA assay performed significantly better (P < 0.05) than the TWB assay. The LIA assay can be considered to be a valid alternative confirmatory test for the serological diagnosis of syphilis.

    Full Text Available Abstract Background In recent years, the number of syphilis cases has stabilised in many countries of Western Europe, however several countries have reported increases among men who have sex with men (MSM. The aim of this article was to describe the epidemiology of early syphilis in Norway in 1992-2008. Methods Cases of early syphilis and congenital syphilis reported to the Norwegian Surveillance System for Communicable Diseases (MSIS 1992-2008 were described by route of transmission, gender, age, birthplace, stage of disease, HIV co-infection, source partner and place of infection. Results The incidence of reported syphilis ranged from 0.05 (1992 to 1.50 (2002 per 100 000 person-years. Of 562 cases reported to MSIS during the study period, 62% were men infected by another man. The proportion of those, infected homosexually increased from 0 (1992-1994 to 77% (2008. Most of them were Norwegians (83%. The proportion of HIV co-infection among homosexually infected increased over time and reached 39% in 2008. The majority reported being infected by a casual partner (73% and in the municipality of Oslo (72%. Of 152 heterosexually infected men 64% were Norwegians; 51% were infected by casual contacts and 20% by commercial sex workers; 73% were infected abroad. Among 56 women, 57% were Norwegians, 57% were infected by a steady partner and 40% were infected abroad. Almost half (46% were diagnosed in the early latent stage. Four cases had congenital syphilis, two of whom were adopted from abroad. Conclusions Syphilis is rare in Norway, but MSM represent almost two thirds of cases. The increase of HIV co-infected cases among MSM may enhance transmission of both infections. We recommend sexually active MSM to be tested for syphilis 2-4 times a year. Due to its variable clinical course, syphilis might be difficult to recognise at an early stage among women in a low-prevalence population. We estimate current practice of prenatal screening in Norway as

    Screening for syphilis infection is currently recommended for high-risk individuals, including those with previous syphilis infection, an infected sexual partner, HIV infection, or more than 4 sex partners in the preceding year. To update a 2004 systematic review of studies of syphilis screening effectiveness, test accuracy, and screening harms in nonpregnant adults and adolescents. Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews through October 2015 and Ovid MEDLINE (January 2004 to October 2015), with updated search through March 2016. English-language trials and observational studies of screening effectiveness, test accuracy, and screening harms in nonpregnant adults and adolescents. One investigator abstracted data, a second checked data for accuracy, and 2 investigators independently assessed study quality using predefined criteria. Transmission of disease, including HIV; complications of syphilis; diagnostic accuracy; and harms of screening. No evidence was identified regarding the effectiveness of screening on clinical outcomes or the effectiveness of risk assessment instruments; the harms of screening; or the effectiveness of screening in average-risk, nonpregnant adolescents or adults or high-risk individuals other than men who have sex with men (MSM) or men who are HIV positive. Four non-US studies indicated higher rates of syphilis detection with screening every 3 months vs 6 or 12 months for early syphilis in HIV-positive men or MSM. For example, there was an increased proportion of asymptomatic, higher-risk MSM in Australia (n = 6789 consultations) receiving a diagnosis of early syphilis when tested every 3 months vs annually (53% vs 16%, P = .001), but no difference among low-risk MSM. Treponemal and nontreponemal tests were accurate in asymptomatic individuals (sensitivity >85%, specificity >91%) in 3 studies but required confirmatory testing.

    Background Syphilis is a major public health problem in many regions of China, with increases in congenital syphilis (CS) cases causing concern. The Chinese Ministry of Health recently announced a comprehensive 10-y national syphilis control plan focusing on averting CS. The decision analytic model presented here quantifies the impact of the planned strategies to determine whether they are likely to meet the goals laid out in the control plan. Methods and Findings Our model incorporated data on age-stratified fertility, female adult syphilis cases, and empirical syphilis transmission rates to estimate the number of CS cases associated with prenatal syphilis infection on a yearly basis. Guangdong Province was the focus of this analysis because of the availability of high-quality demographic and public health data. Each model outcome was simulated 1,000 times to incorporate uncertainty in model inputs. The model was validated using data from a CS intervention program among 477,656 women in China. Sensitivity analyses were performed to identify which variables are likely to be most influential in achieving Chinese and international policy goals. Increasing prenatal screening coverage was the single most effective strategy for reducing CS cases. An incremental increase in prenatal screening from the base case of 57% coverage to 95% coverage was associated with 106 (95% CI: 101, 111) CS cases averted per 100,000 live births (58% decrease). The policy strategies laid out in the national plan led to an outcome that fell short of the target, while a four-pronged comprehensive syphilis control strategy consisting of increased prenatal screening coverage, increased treatment completion, earlier prenatal screening, and improved syphilis test characteristics was associated with 157 (95% CI: 154, 160) CS cases averted per 100,000 live births (85% decrease). Conclusions The Chinese national plan provides a strong foundation for syphilis control, but more comprehensive measures

    Full Text Available Introduction. The incidence of syphilis continues to rise in the United States over the past 15 years. This disease process is classified into stages and may present with a coinfection of Human Immunodeficiency Virus (HIV. Case Report. We present a case of a 32-year-old African American male who presented with cutaneous manifestations of secondary syphilis and transaminitis. A workup revealed that the transaminitis was secondary to underlying syphilitic hepatitis in the presence of HIV coinfection. The patient had a reactive rapid plasma reagin (RPR of 1 : 64 TU and reactive Treponema pallidum particle agglutination assay (TPPA. Lab findings showed alkaline phosphate (ALP of 648 unit/L, aspartate aminotransferase (AST of 251 unit/L, and alanine aminotransferase (ALT of 409 unit/L. Conclusion. Syphilitic hepatitis is a recognized entity in the medical literature. It is a manifestation of secondary syphilis and it is more commonly seen in coinfected patients with both syphilis and HIV. Therefore, primary care physicians should keep infectious etiologies (e.g., syphilis and HIV in the differential diagnosis of patients who present with unexplained liver dysfunction in a cholestatic pattern.

    "Probable active syphilis," is defined as seroreactivity in both non-treponemal and treponemal tests. A correction factor of 65%, namely the proportion of pregnant women reactive in one syphilis test type that were likely reactive in the second, was applied to reported syphilis seropositivity data reported to WHO for global estimates of syphilis during pregnancy. To identify more accurate correction factors based on test type reported. Medline search using: "Syphilis [Mesh] and Pregnancy [Mesh]," "Syphilis [Mesh] and Prenatal Diagnosis [Mesh]," and "Syphilis [Mesh] and Antenatal [Keyword]. Eligible studies must have reported results for pregnant or puerperal women for both non-treponemal and treponemal serology. We manually calculated the crude percent estimates of subjects with both reactive treponemal and reactive non-treponemal tests among subjects with reactive treponemal and among subjects with reactive non-treponemal tests. We summarized the percent estimates using random effects models. Countries reporting both reactive non-treponemal and reactive treponemal testing required no correction factor. Countries reporting non-treponemal testing or treponemal testing alone required a correction factor of 52.2% and 53.6%, respectively. Countries not reporting test type required a correction factor of 68.6%. Future estimates should adjust reported maternal syphilis seropositivity by test type to ensure accuracy.

    To systematically review and estimate pooled sensitivity and specificity of the polymerase chain reaction (PCR) technique compared to recommended reference tests in the diagnosis of suspected syphilis at various stages and in various biological materials. Systematic review and meta-analysis. Search of three electronic bibliographic databases from January 1990 to January 2012 and the abstract books of five congresses specialized in the infectious diseases' field (1999-2011). Search key terms included syphilis, Treponema pallidum or neurosyphilis and molecular amplification, polymerase chain reaction or PCR. We included studies that used both reference tests to diagnose syphilis plus PCR and we presented pooled estimates of PCR sensitivity, specificity, and positive and negative likelihood ratios (LR) per syphilis stages and biological materials. Of 1160 identified abstracts, 69 were selected and 46 studies used adequate reference tests to diagnose syphilis. Sensitivity was highest in the swabs from primary genital or anal chancres (78.4%; 95% CI: 68.2-86.0) and in blood from neonates with congenital syphilis (83.0%; 55.0-95.2). Most pooled specificities were ∼95%, except those in blood. A positive PCR is highly informative with a positive LR around 20 in ulcers or skin lesions. In the blood, the positive LR was syphilis diagnosis in lesions. PCR is a useful diagnostic tool in ulcers, especially when serology is still negative and in medical settings with a high prevalence of syphilis.

    To estimate the rate of HIV and syphilis coinfection among pregnant women living in Porto Alegre, Brazil, as well as the association of coinfection with vertical HIV transmission and socioeconomic variables. This analytical retrospective cross-sectional study employed data from the regular epidemiological surveillance system for the period from 2010 to 2013. Data were obtained regarding pregnant women with HIV and exposed children, syphilis in pregnancy, and congenital syphilis. The study population included 1 500 HIV-positive women with deliveries from 2010 to 2013. Of these, 155 (10.3%) were also infected with syphilis, corresponding to an HIV and syphilis coinfection rate of 10.2% (± 1.5%). The coinfected group had lower education levels, higher prevalence of black women, and greater HIV exposure related to drug use by the woman or a partner. Coinfected women had more delayed HIV diagnosis (for example, during childbirth) and greater prevalence of lacking prenatal care (44%). Crude analysis showed an association between vertical HIV transmission and HIV and syphilis co-infection (PR = 2.1; 95%CI: 1.21-3.74; P = 0.01) that persisted in the adjusted analysis. A profile of increased vulnerability was identified among pregnant women with HIV and syphilis coinfection. A positive impact of the treatment to reduce congenital syphilis and eliminate vertical transmission of HIV depends on enhanced access to qualified health care.

    This retrospective study assessed whether Quality Improvement Scotland national standards for the sexual health care offered to HIV-positive individuals are being met by the Edinburgh genitourinary (GU) medicine clinic; specifically whether HIV-positive patients are offered: (a) sexually transmitted infection (STI) screening annually and (b) syphilis testing six-monthly. The study also reviewed what factors were associated with a clinician's offer of STI screening and syphilis testing. Of the 509 patients seen within the study period, case notes documented that 64% were offered STI screens, and 69% were offered syphilis testing, results consistent with audits of services elsewhere. Sexual orientation (P offer of STI screening, while gender (P offer of syphilis testing. Our results suggest that one explanation for clinicians failing to offer STI screens and syphilis serology testing is their (implicit) risk assessment that STI testing is not required in individual patients.

    OBJECTIVE: To implement and describe a novel syphilis screening strategy for blood donors. BACKGROUND: The seroprevalence of syphilis in blood donors is often high in low- and middle-income countries (LMIC) although the proportion of infectious donations is probably low. Syphilis screening may...... not happen at all; or the use of non-specific screening tests, which have high false positive rates, results in many donations being discarded unnecessarily. This can have a critical effect on already inadequate blood supplies. MATERIALS AND METHODS: Blood donors were screened at the time of donation...... negative were released to stock and test-positive units discarded. RESULTS: Of the 2213 blood donors, 182 (8·2%; 182/2213) screened positive by RDT. In addition, 38 out of these 182 (20·9%) were RPR positive on post-donation testing. Over 2 months there was a 79% reduction in blood units discarded due...

    Full Text Available Objective: to investigate the perception of nurses of the Family Health Strategy on the factors that influence adhesion to treatment of sexual partners of pregnant women with syphilis. Methods: it is a qualitative research, made with 10 nurses. To collect data, a semi-structured interview was used. The data were submitted to thematic analysis. Results: the following categories were identified: the approach of the nurses to partners of pregnant women with syphilis; barriers that influence on the adhesion to the treatment; strategies and actions of adhesion of the partners in the treatment; perception of the nurse concerning the responsibility of assistance and effectiveness of the treatment. Conclusion: it was identified that nurses have a wide perception of aspects relating to adhesion to the treatment, but need better scientific and practical basis to perform effectively activities on the management of sexual partners with syphilis.

    Anetoderma is a rare benign condition of diverse etiology whose characteristic is the diminution or absence of the dermal elastic fibers. Classified as primary and secondary, the latter associated with tumors, inflammatory, and infectious diseases. Although the etiology of the lesions is well described in literature, the pathogenesis is still poorly determined. Anetoderma in syphilis is rare, and occurs even in the most uncommon cutaneous manifestations of the disease, such as the nodular form. In order to better understand the changes that lead to elastolysis, we propose a better correlation with the histopathological findings of the lesions that precede it. We present two cases of anetoderma secondary to syphilis, whose clinical aspects resembled the pattern of their initial secondary syphilis rash.

    To study quantitative change of cerebral blood flow (CBF) on patients with early syphilis, the authors have established a method on absolute measurement of rCBF by using SPECT with Ethyl Cysteinate Dimmer (ECD) as imaging agent, and the method was applied to measure rCBF on patients with early syphilis. The rCBF values measured by this method are highly consistent with the values measured by other classical methods such as SPECT ( 123 I-IMP) and PET( 15 O-H 2 O). The rCBF values for early syphilis patients and the normal control show some statistical differences. A routine quantitative absolute measurement of rCBF featured with simple procedures is therefore on the way of maturation. (authors)

  8. Syphilis may be a confounding factor, not a causative agent, in syphilitic ALS.

    2016-01-01

    Based upon a review of published clinical observations regarding syphilitic amyotrophic lateral sclerosis (ALS), I hypothesize that syphilis is actually a confounding factor, not a causative factor, in syphilitic ALS. Moreover, I propose that the successful treatment of ALS symptoms in patients with syphilitic ALS using penicillin G and hydrocortisone is an indirect consequence of the treatment regimen and is not due to the treatment of syphilis. Specifically, I propose that the observed effect is due to the various pharmacological activities of penicillin G ( e.g ., a GABA receptor antagonist) and/or the multifaceted pharmacological activity of hydrocortisone. The notion that syphilis may be a confounding factor in syphilitic ALS is highly relevant, as it suggests that treating ALS patients with penicillin G and hydrocortisone-regardless of whether they present with syphilitic ALS or non-syphilitic ALS-may be effective at treating this rapidly progressive, highly devastating disease.

    Screening for HIV and syphilis in key populations is recommended by the WHO to reduce the morbidity, mortality and transmission associated with undiagnosed and untreated infections. Rapid point-of-care tests that can detect multiple infections with a single fingerprick whole blood specimen using a single device are gaining popularity. We evaluated the field performance of a rapid dual HIV and syphilis test in people at high risk of HIV and syphilis infections. Participants included men who have sex with men and transgender women recruited in Lima, Peru. Reference standard testing for detection of HIV and syphilis infections, conducted using blood samples from venipuncture, included Treponema pallidum particle agglutination and fourth-generation HIV enzyme immunoassay for which positive results had a confirmation HIV Western blot test. For the evaluation test, SD BIOLINE HIV/Syphilis Duo test (Standard Diagnostics, Korea), a fingerprick blood specimen was used. Sensitivity and specificity were calculated and the exact binomial method was used to determine 95% CIs. A total of 415 participants were recruited for the study. The dual test sensitivity for detection of T. pallidum infection was 89.2% (95% CI 83.5% to 93.5%) and specificity 98.8% (95% CI 96.5% to 99.8%). For detection of HIV infection, the sensitivity of the dual test was 99.1% (95% CI 94.8% to 100%) and specificity 99.4% (95% CI 97.7% to 99.9%). This high performing dual test should be considered for the use in clinical settings to increase uptake of simultaneous testing of HIV and syphilis and accelerate time to treatment for those who need it.

    The diagnosis of neurosyphilis (NS) is a challenge, especially in HIV-infected patients, and the criteria for deciding when to perform a lumbar puncture (LP) in HIV-infected patients with syphilis are controversial. We retrospectively reviewed demographic, clinical, and laboratory data from 122 cases of HIV-infected patients with documented early syphilis who underwent an LP to rule out NS, and we evaluated 3 laboratory-developed validated real-time PCR assays, the Treponema pallidum particle agglutination (TPPA) assay, the fluorescent treponemal antibody absorption (FTA-ABS) assay, and the line immunoassay INNO-LIA Syphilis, for the diagnosis of NS from cerebrospinal fluid (CSF) samples of these patients. NS was defined by a reactive CSF-VDRL test result and/or a CSF white blood cell (WBC) count of >20 cells/μl. Thirty of the 122 patients (24.6%) had early NS. Headache, visual symptoms, a CD4 cell count of FTA-ABS, TPPA, and INNO-LIA assays had sensitivities of 58%, 100%, 68%, and 100%, specificities of 67%, 12%, 49%, and 13%, and negative predictive values of 85%, 100%, 84%, and 100%, respectively. Visual disturbances, headache, uncontrolled HIV-1 viremia, and a CD4 cell count of <500 cells/μl were predictors of NS in HIV-infected patients with early syphilis, while blood serum RPR titers were not; therefore, RPR titers should not be used as the sole criterion for deciding whether to perform an LP in early syphilis. When applied to CSF samples, the INNO-LIA Syphilis assay easily helped rule out NS.

    A syphilis diagnosis is often aided by the detection of treponemal and nontreponemal 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. Among the 4,134 routine and HIV samples tested by the two automated assays, the percentage of agreement was excellent at 99.0% (95% confidence interval [CI], 98.6% to 99.2%; κ, 0.89), with the Lumipulse G TP-N having a shorter time to first and subsequent results. All specimens with reactive syphilis screening results were further tested by rapid plasma reagin (RPR) and Treponema pallidum particle agglutination (TP·PA) testing ( n = 231). The results from the RPR-reactive samples ( n = 82) showed complete concordance with the two automated assays, while the TP·PA assay displayed some discrepancies. The positive percent agreement (PPA) and negative percent agreement (NPA) between the TP·PA test and the Lumipulse G TP-N test were 98.9% and 77.3%, respectively. The Bioplex 2200 Syphilis IgG immunoassay displayed a similar PPA (100%) but a substantially lower NPA (15.9%). Patient chart reviews of discrepant results suggested that the Lumipulse G TP-N assay produced 27 fewer falsely reactive results and can reduce the amount of additional confirmatory RPR and TP·PA testing needed. The analogous performance characteristics of the two automated systems indicate that the Lumipulse G TP-N assay is suitable for high-throughput syphilis screening.

    Full Text Available Abstract Background Syphilis causes up to 1,500,000 congenital syphilis cases annually. These could be prevented if all pregnant women were screened, and those with syphilis treated with a single dose of penicillin before 28 weeks gestation. In recent years, rapid point-of-care tests have allowed greater access to syphilis screening, especially in rural or remote areas, but the lack of quality assurance of rapid testing has been a concern. We determined the feasibility of using dried blood spots (DBS as specimens for quality assurance of syphilis serological assays. Methods We developed DBS extraction protocols for use with Treponema pallidum particle agglutination assay (TPPA, Treponema pallidum haemagglutination assay (TPHA and an enzyme immunoassay (EIA and compared the results with those using matching plasma samples from the same patient. Results Since DBS samples showed poor performance with TPHA and EIA (TPHA sensitivity was 50.5% (95% confidence interval: 39.9–61.2% and EIA specificity was 50.4% (95% CI: 43.7–57.1%, only the DBS TPPA was used in the final evaluation. DBS TPPA showed an sensitivity of 95.5% (95% CI: 91.3–98.0% and a specificity of 99.0% (95% CI: 98.1–99.5% compared to TPPA using plasma samples as a reference. Conclusion DBS samples can be recommended for use with TPPA, and may be of value for external quality assurance of point-of-care syphilis testing.

    Syphilis is a resurging sexually transmitted infection linked to Treponema Pallidum. Syphilitic lymphadenitis can be present during the 3 stages of the disease. Its histological diagnosis remains challenging for the pathologist given its possible misleading aspect and its ability to mimic as well as reactional as tumoral conditions. We report the case of an HIV-infected young patient referred for suspicion of an aggressive lymphoma. Histological and immunohistochemical analysis of cervical lymphadenopathy revealed secondary syphilis. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Abstract Background In the past 15 years, a recrudescence of syphilis was observed in Canada, along with a surge in ocular syphilis cases. Without treatment, ocular syphilis can have serious consequences potentially leading to blindness. Our goal was to describe the demographics, clinical presentations, proportion of co-infection with HIV, treatments and visual outcomes of ocular syphilis cases. Methods Patients with a confirmed positive syphilis serology between 2000 and 2015 were identified through the reference laboratory database. A retrospective chart review was performed for those who visited the ophthalmology clinic of Hôpital Maisonneuve-Rosemont or Hôpital Notre-Dame to identify ocular syphilis cases. Results Among the 119 patients (174 eyes) identified (2.5% of the population screened), 80% were male; of which 63% were MSM. Mean presenting logMAR visual acuity was 0.70 (20/100 Snellen) and unilateral ocular involvement occurred in 54%. Ocular manifestations included interstitial keratitis (24 eyes), anterior uveitis (37 eyes), intermediate uveitis (17 eyes), posterior uveitis (31 eyes), panuveitis (27 eyes), isolated optic nerve involvement (25 eyes), and others (12 eyes) including VI nerve palsy, scleritis, and episcleritis. Cerebrospinal fluid (CSF) examination was done in 65 (55%) patients. Of those, VDRL was positive in 14 (22%) patients; white blood cells and proteins were elevated in, respectively, 28 (43%) and 39 (60%) of patients. HIV status was unknown in 39 (33%) patients; among those whose serology were performed (or previous status was known), 38 (48%) were HIV infected. Intravenous aqueous penicillin G was administered in 69 (58%), intramuscular benzathine penicillin in 25 (21%) and other antibiotics, mainly due to allergy, in three (3%) patients. Treatment allowed a visual improvement of –0.22 logMAR (gain of five lines on Snellen chart) after a mean follow-up period of 19 months. Conclusion Syphilis can manifest with a widely

    Anticardiolipin antibodies are produced both in patients with the antiphospholipid syndrome (APS) and in patients with syphilis, but lupus anticoagulant activity has been reported only for the former group. To understand these differences, affinity-purified immunoglobulin G anticardiolipin antibodies from APS (n = 11) and syphilis (n = 5) patients were compared. Only the antibodies from the APS group inhibited prothrombin conversion to thrombin and cross-reacted with phosphatidylserine. These findings may enable better definition of the phospholipid epitopes involved in the hemostatic abnormalities of APS. PMID:8063429

    Objective: To study the clinical value of cerebral blood flow imaging for evaluation of patients with early syphilis. Methods: Fifty-three patients with early syphilis underwent cerebral blood flow imaging using 99 Tc m -ethylenecysteinate dimer(ECD). Regional cerebral blood flow (rCBF) changes were analyzed. Results: The acquired images of 53 patients were graded as 5 types. The rCBF was significantly depressed in 48 of 53 patients mainly in the areas dominated by anterior cerebral artery and middle cerebral artery. Conclusion: Treponema pallidum (TP) could start invading central nervous system at the early stage of infection

    Syphilis in pregnancy is an under-recognized public health problem, especially in sub-Saharan Africa which accounts for over 60% of the global burden of syphilis. If left untreated, more than half of maternal syphilis cases will result in adverse pregnancy outcomes including stillbirth and fetal loss, neonatal death, prematurity or low birth weight, and neonatal infections. Achieving universal coverage of antenatal syphilis screening and treatment has been the focus of the global campaign for the elimination of mother-to-child transmission of syphilis. However, little is known about the availability of antenatal syphilis screening and treatment across sub-Saharan Africa. The objective of this study was to estimate the 'likelihood of appropriate care' for antenatal syphilis screening and treatment by analyzing health facility surveys and household surveys conducted from 2010 to 2015 in 12 sub-Saharan African countries. In this secondary data analysis, we linked indicators of health facility readiness to provide antenatal syphilis detection and treatment from Service Provision Assessments (SPAs) and Service Availability and Readiness Assessments (SARAs) to indicators of ANC use from the Demographic and Health Surveys (DHS) to compute estimates of the 'likelihood of appropriate care'. Based on data from 5,593 health facilities that reported offering antenatal care (ANC) services, the availability of syphilis detection and treatment in ANC facilities ranged from 2% to 83%. The availability of syphilis detection and treatment was substantially lower in ANC facilities in West Africa compared to the other sub-regions. Levels of ANC attendance were high (median 94.9%), but only 27% of ANC attendees initiated care at less than 4 months gestation. We estimated that about one in twelve pregnant women received ANC early (<4 months) at a facility ready to provide syphilis detection and treatment (median 8%, range 7-32%). The largest implementation bottleneck identified was low

    Full Text Available Untreated syphilis in pregnancy is associated with adverse clinical outcomes for the infant. Most syphilis infections occur in sub-Saharan Africa (SSA, where coverage of antenatal screening for syphilis is inadequate. Recently introduced point-of-care syphilis tests have high accuracy and demonstrate potential to increase coverage of antenatal screening. However, country-specific cost-effectiveness data for these tests are limited. The objective of this analysis was to evaluate the cost-effectiveness and budget impact of antenatal syphilis screening for 43 countries in SSA and estimate the impact of universal screening on stillbirths, neonatal deaths, congenital syphilis, and disability-adjusted life years (DALYs averted.The decision analytic model reflected the perspective of the national health care system and was based on the sensitivity (86% and specificity (99% reported for the immunochromatographic strip (ICS test. Clinical outcomes of infants born to syphilis-infected mothers on the end points of stillbirth, neonatal death, and congenital syphilis were obtained from published sources. Treatment was assumed to consist of three injections of benzathine penicillin. Country-specific inputs included the antenatal prevalence of syphilis, annual number of live births, proportion of women with at least one antenatal care visit, per capita gross national income, and estimated hourly nurse wages. In all 43 sub-Saharan African countries analyzed, syphilis screening is highly cost-effective, with an average cost/DALY averted of US$11 (range: US$2-US$48. Screening remains highly cost-effective even if the average prevalence falls from the current rate of 3.1% (range: 0.6%-14.0% to 0.038% (range: 0.002%-0.113%. Universal antenatal screening of pregnant women in clinics may reduce the annual number of stillbirths by up to 64,000, neonatal deaths by up to 25,000, and annual incidence of congenital syphilis by up to 32,000, and avert up to 2.6 million

    Continued surveillance of the HIV epidemic is critical to monitor changes in trends and risk behaviors. A 2005 study in the Cameroonian Armed Forces (CAF) found an HIV prevalence of 11.3% among male and female service members. The purpose of the current study is to determine the 5-year change in the HIV prevalence, estimate the prevalence of syphilis, and examine factors associated with infection in the CAF. Participants were male and female service members 18 years of age or older who were stationed at one of the 10 military garrisons selected for participation. The military garrisons included in this study were proportionally representative of the CAF by geographic region. Military companies and individuals within the selected garrisons were randomly chosen to participate in the study. Demographic and behavioral risk data were collected from September-November 2011 using personal interviews. Blood was collected for HIV and syphilis testing. Of 2,523 participants tested, 6.0% screened positive for HIV [includes 5.3% who screened positive for HIV only and 0.7% who screened positive for both HIV and syphilis], and 3.1% screened positive for syphilis only. Analyses examining risk factors associated with HIV/syphilis infection (i.e., infected with HIV, infected with syphilis, or co-infected with both HIV and syphilis) were restricted to 2,255 men who reported ever having sex. In a multivariate logistic regression model, the odds of testing positive for HIV/syphilis were higher among men who were separated, divorced, or widowed (adjusted odds ratio [AOR]=3.13, 95% confidence interval [CI]: 1.24-7.89), had sex with sex workers (AOR=1.64, 95% CI: 1.19-2.27), and reported a genital sore/ulcer in the past 12 months preceeding the survey (AOR=1.73, 95% CI: 1.05-2.86). Higher HIV knowledge was protective against HIV/syphilis infection (AOR=0.73, 95% CI: 0.54-0.99). While the overall HIV prevalence in this sample of military personnel was lower than previously reported (6

    To determine the diagnostic performance of the SD BIOLINE HIV/syphilis Duo rapid test. A hospital-based cross-sectional study. This evaluation was conducted at one of the largest hospitals in southern Ethiopia. Serum samples obtained from clients attending the antiretroviral therapy and voluntary counselling and testing centres were used. Sera were originally collected for the purpose of investigating syphilis epidemiology. The performance of the test to detect HIV was evaluated using 400 sera (200 HIV positives and 200 HIV negatives). Also, its performance to detect syphilis was evaluated using 85 syphilis positive and 100 syphilis negative serum samples. Individuals tiebreaker to determine the result. We also used ELISA to resolve discordant HIV results. Syphilis serostatus was determined using the Treponema pallidum haemagglutination assay (TPHA). The respective sensitivity, specificity, positive predictive value and negative predictive value of the SD BIOLINE HIV/syphilis Duo test were 100, 99.5, 99.5 and 100% for HIV and 97.6, 96, 95.4 and 98% for syphilis testing, respectively. In reference to TPHA, the test kit reported 4 false positives and 2 false negative results for syphilis. The κ values were 0.99 for HIV testing and 0.94 for syphilis testing. The excellent performance of the SD BIOLINE HIV/syphilis Duo test to detect HIV as well as syphilis facilitates the integration of syphilis testing and treatment to the already established HIV prevention programme, ultimately contributing to the dual HIV and syphilis elimination goal.

    Background The epidemiology of incident syphilis infection among HIV-1-infected men who have sex with men (MSM) largely remains unknown. Methods The incidence and risk factors for incident syphilis (positive TPHA and RPR> = 1:8) among HIV-1-infected MSM who visited a large HIV clinic in Tokyo for the first time between 2008 and 2013 were determined, using clinical data and stored blood samples taken every three months for screening and determination of the date of incident syphilis. Poisson regression compared the incidence of syphilis at different observation periods. Results Of 885 HIV-1-infected MSM with baseline data, 34% either presented with active syphilis at baseline (21%) or became infected with syphilis during follow-up (13%). After excluding 214 patients (MSM with syphilis at baseline (n = 190) and no follow-up syphilis test (n = 24)), of 671 men, 112 (17%) developed incident syphilis with an incidence of 43.7/1,000 person-years [95% CI, 36.5–52.3]. The incidence decreased slightly during observation period although the trend was not significant (2008–2009: 48.2/1,000 person-years, 2010–2011: 51.1/1,000 person-years, 2012–2013: 42.6/1,000 person-years, 2014 to 2015: 37.9/1,000 person-years, p = 0.315). Multivariable analysis identified young age (40, HR 4.0, 95%CI 2.22–7.18, psyphilis at baseline (HR 3.0, 95%CI 2.03–4.47, psyphilis. Incidence of syphilis was particularly high among young patients (age syphilis were asymptomatic. Conclusions Although incidence of syphilis did not increase during the observation period, it was high among HIV-1-infected MSM, especially among young HIV-1-infected MSM and those with history of syphilis, in Tokyo. Regular screening for syphilis needs to be strictly applied to this population. PMID:27992604

    Globally, men who have sex with men (MSM) are disproportionately burdened with syphilis. This review describes the published literature on trends in syphilis infections among MSM in the US and Western Europe from 1998, the period with the fewest syphilis infections in both geographical areas, onwards. We also describe disparities in syphilis trends among various sub-populations of MSM. We searched electronic databases (Medline, Embase, Global Health, PsychInfo, CAB Abstracts, CINAHL, Sociological Abstracts, Web of Science, Cochrane Library, and LILACS) for peer-reviewed journal articles that were published between January 2004 and June 2015 and reported on syphilis cases among MSM at multiple time points from 1998 onwards. Ten articles (12 syphilis trend studies/reports) from the US and eight articles (12 syphilis trend studies/reports) from Western Europe were identified and included in this review. Taken together, our findings indicate an increase in the numbers and rates (per 100,000) of syphilis infections among MSM in the US and Western Europe since 1998. Disparities in the syphilis trends among MSM were also noted, with greater increases observed among HIV-positive MSM than HIV-negative MSM in both the US and Western Europe. In the US, racial minority MSM and MSM between 20 and 29 years accounted for the greatest increases in syphilis infections over time whereas White MSM accounted for most syphilis infections over time in Western Europe. Multiple strategies, including strengthening and targeting current syphilis screening and testing programs, and the prompt treatment of syphilis cases are warranted to address the increase in syphilis infections among all MSM in the US and Western Europe, but particularly among HIV-infected MSM, racial minority MSM, and young MSM in the US.

    Objectives. We examined perceptions of and attitudes toward existing and potential syphilis interventions, including case management and Web-based programs, to increase syphilis testing among high-risk men who have sex with men (MSM). Methods. Between October 2010 and June 2011, we conducted in-depth interviews with 19 MSM in Los Angeles, California, with repeat early syphilis infections (primary, secondary, and early latent syphilis) within the previous 5 years. We analyzed the interviews inductively to determine the most acceptable potential interventions. Results. Experiences with health department and community-based standard of care case management were generally positive. The most popular interventions among respondents included a Web site providing information on syphilis and syphilis testing, automated Web reminders to test, being paid to test, free online home testing kits, and preexposure prophylactic medication. Respondents’ beliefs that they would continue to practice high-risk sexual behaviors reinforced their reasons for wanting increased accessibility and convenient testing strategies. Conclusions. Public health officials should consider participant responses to potential interventions for syphilis, which suggest that high-risk MSM would consider testing more often or using other interventions.

    In Germany, the number of reported syphilis cases increased between 11% and 22% per year between 2010 and 2014. We analysed syphilis surveillance data and data of four behavioural surveys on men who have sex with men (MSM) in Germany (2003, 2007, 2010, 2013) to assess if this rise is ongoing and to find possible explanations for it. Syphilis notifications increased in 2015 by 19% to a total of 6,834. This was mainly due to increasing notifications in MSM of all age groups in larger German cities. Data from the behavioural surveys on MSM in Germany showed a simultaneous increase of selective condom use as HIV-status-bases risk management strategy and the number of syphilis cases. MSM diagnosed with HIV reported condomless anal intercourse with non-steady partners more frequent than MSM not diagnosed with HIV or untested for HIV, but the latter also reported higher frequencies of this behaviour in the more recent surveys. Transmission in HIV-positive MSM probably plays an important, but not exclusive role, for the syphilis dynamics in Germany. A risk adapted routine screening for sexually active MSM and potentially innovative approaches to increase early screening and treatment of syphilis such as internet counselling, home sampling, home testing and broadening venue-based (rapid) testing, should be critically evaluated to effectively reduce syphilis infections.

    To determine the prevalence and correlates of Herpes Simplex Virus-2 (HSV-2) and syphilis infections in the general population in India. 2456 adults were surveyed in Hyderabad, Bangalore and Chandigarh in India. Socio-demographic and lifestyle characteristics were obtained through a questionnaire, and a dried blood spot (DBS) was collected from all individuals aged 18 years and over; sexual behaviour was collected from those aged 18-49 years. DBS samples were tested for HSV-2 and syphilis serology. The association between HSV-2 and syphilis infections with socio-demographic and behavioural variables was analysed using multivariable logistic regression. The prevalence of HSV-2 and syphilis was 10.1% and 1.7%, respectively. Geographic differences in HSV-2 prevalence were significant, while for syphilis it was comparable. Urban-rural differences in prevalence were only seen for syphilis. For both infections, the prevalence between males and females was not significantly different. In males and females, HSV-2 prevalence increased significantly with increasing age; for syphilis, a slight trend was seen only in females. In a multivariable analysis, HSV-2 infection in males and females was associated with site, religion and testing positive for syphilis, in addition to reporting ≥ 2 lifetime partners in the previous year among males and being ever married or having had sex with a non-regular partner in the last year among females. The burden and geographic heterogeneity of HSV-2 and syphilis infections in India are significant. A national household and DBS-based sexually transmitted infection (STI) surveillance system would enable monitoring, especially in relation to the HIV epidemic, and planning of evidence-based prevention and treatment programmes.

    Full Text Available Abstract Background Syphilis has made a dramatic resurgence in China during the past two decades and become the third most prevalent notifiable infectious disease in China. Female sex workers (FSWs have become one of key populations for the epidemic. In order to investigate syphilis infection among different tiers of FSWs, a cross-sectional study was conducted in 8 sites in China. Methods Serum specimens (n = 7,118 were collected to test for syphilis and questionnaire interviews were conducted to obtain socio-demographic and behavioral information among FSWs recruited from different types of venues. FSWs were categorized into three tiers (high-, middle- and low-tier FSWs based on the venues where they solicited clients. Serum specimens were screened with enzyme-linked immunosorbent assay (ELISA for treponemal antibody followed by confirmation with non-treponemal toluidine red unheated serum test (TRUST for positive ELISA specimens to determine syphilis infection. A logistic regression model was used to determine factors associated with syphilis infection. Results Overall syphilis prevalence was 5.0% (95%CI, 4.5-5.5%. Low-tier FSWs had the highest prevalence (9.7%; 95%CI, 8.3-11.1%, followed by middle-tier (4.3%; 95%CI, 3.6-5.0%, P P Conclusions This multi-site survey showed a high prevalence of syphilis infection among FSWs and substantial disparities in syphilis prevalence by the tier of FSWs. The difference in syphilis prevalence is substantial between different tiers of FSWs, with the highest rate among low-tier FSWs. Thus, current surveillance and intervention activities, which have low coverage in low-tier FSWs in China, should be further examined.

    Outbreaks of syphilis have been described among HIV-infected men who have sex with men (MSM) in Western communities, whereas reports in Asian countries are limited. We aimed to characterize the incidence and temporal trends of syphilis among HIV-infected MSM compared with HIV-infected non-MSM in Asian countries. Patients enrolled in the TREAT Asia HIV Observational Database cohort and with a negative non-treponemal test since enrolment were analyzed. Incidence of syphilis seroconversion, defined as a positive non-treponemal test after previously testing negative, was evaluated among patients at sites performing non-treponemal tests at least annually. Factors associated with syphilis seroconversion were investigated at sites doing non-treponemal testing in all new patients and subsequently testing routinely or when patients were suspected of having syphilis. We included 1010 patients from five sites that performed non-treponemal tests in all new patients; those included had negative non-treponemal test results during enrolment and subsequent follow-ups. Among them, 657 patients were from three sites conducting regular non-treponemal testing. The incidence of syphilis seroconversion was 5.38/100 person-years (PY). Incidence was higher in MSM than non-MSM (7.64/100 PY vs. 2.44/100 PY, psyphilis diagnosis (IRR 5.15, 95% CI 3.69-7.17) and younger age (IRR 0.84 for every additional 10 years, 95% CI 0.706-0.997) were significantly associated with syphilis seroconversion. We observed a higher incidence of syphilis seroconversion among HIV-infected MSM and a trend to increasing annual incidence. Regular screening for syphilis and targeted interventions to limit transmission are needed in this population.

    The burden of sexually transmitted infections (STIs), such as syphilis, is higher in low-income countries, with serious consequences and profound impact on sexual and reproductive health and human immunodeficiency virus (HIV) spread. Syphilis prevalence tend to be higher among people who misuse drugs than in the general population. To assess syphilis and associated factors among polydrug users (PDU) in the city of Salvador, Northeast Brazil. A cross-sectional study was conducted in 10 Brazilian cities between September and November 2009 using Respondent Driven Sampling (RDS). Participants answered an Audio Computer-Assisted Self Interview (ACASI) and were rapid tested for HIV and syphilis. We performed multivariable regression models for correlates of syphilis on Stata 10.0. Estimates were weighted by the inverse size of the individual social network size and homophily. Mean age was 29.3 years (range: 18-62), 74.0% were males, and 89.8% were non-white. Syphilis prevalence was 16.6%. Females (adjwOR:2.14; 95%CI:1.09-4.20), individuals over 29 years old (adjwOR:4.44; 95%CI:2.41-8.19), those who exchanged sex for money or drugs (adjwOR:3.51; 95%CI:1.84-6.71), "No/low" self-perceived risk of HIV infection (adjwOR:5.13; 95%CI:1.36-19.37), and having nine or less years of education (adjwOR:2.92; 95%CI:1.08-7.88) were associated with syphilis. One of the most pressing needs for syphilis prevention/control is the availability of rapid point-of-care diagnostic tests and treatment. Interventions should be tailored to PDU needs and their multiple burdens as shown in the present study, that may contribute to future studies aiming to better understand the relationships between drug use and syphilis.

    To measure the determinants of syphilis among female sex workers (FSWs) in the state of Karnataka, South India. During 2004-2006, cross-sectional surveys were administered to 2312 FSWs across 5 districts in the state, in the context of a large-scale HIV preventive intervention program. Demographic and behavioral information, and serum (for syphilis, HSV-2 and HIV) and urine specimens (for Neisseria gonorrhoeae and Chlamydia trachomatis) were obtained. The prevalences of lifetime (TPHA positive) and active (RPR and TPHA positive) syphilis were 25.3% and 9.6%, respectively. There was considerable variation in the prevalence between districts, ranging from 10.9% to 37.4% lifetime, and 3.4% to 24.9% active infection. Factors associated with lifetime syphilis were older age, longer duration of sex work, illiteracy, client volume, practising sex work in >1 city, and sex work typology (public solicitation followed by brothel or lodge-based sex). The same typology, client volume, illiteracy, and having been widowed, divorced or deserted, were predictive of active infection. Of the 976 women who had symptoms of an STI, 78.8% had sought medical treatment, behavior that was protective for both outcomes. HIV infection was strongly associated with lifetime (OR 2.0; 95% CI: 1.6-2.6) and active syphilis (OR 2.1; 95% CI: 1.5-2.9). Despite reasonable treatment-seeking behavior, the high prevalence of syphilis has necessitated enhanced outreach efforts for FSWs and acceleration of the implementation of syphilis screening. Mobilizing resources to enhance syphilis control will not only reduce the burden of syphilis morbidity, but should impact in reducing HIV transmission.

    To determine the laboratory-based performance and operational characteristics of three dual rapid diagnostic tests (RDTs) for testing HIV and syphilis. Three dual RDTs (SD Bioline, Chembio, and MedMira) were evaluated using 1514 serum specimens archived at laboratories or collected from clinics in China and Nigeria to determine sensitivity and specificity, with 95% confidence intervals. Concordance of testing results read by two technicians, stability of testing results read at two time points, and test operation characteristics were also assessed. All three of the evaluated RDTs gave excellent performance with a combined sensitivity ranging from 99.0%-99.6% for HIV and 98.3%-99.0% for syphilis, and a combined specificity ranging from 97.9%-99.0% for HIV and 97.2%-99.6% for syphilis. Concordance of testing results between two technicians and stability of testing results read within and one hour past the recommended reading period showed excellent agreement, with Kappa greater than or equal to 0.98. All the tests were found to be very or fairly easy to use and easy to interpret the results. Further evaluations of these dual RDTs with whole blood in field settings, and more studies on the implication of introduction of these tests in HIV and syphilis control programs are needed.

    Syphilis screening by the nontreponemal rapid plasma reagin (RPR) test is not usually followed up by specific treponemal tests in most of the resource poor healthcare settings of Nepal. We analyzed serum specimens of 504 suspected syphilis cases at the immunology department of the national reference laboratory in Nepal during 2007-2009 using RPR test and Treponema pallidum hemagglutination assay (TPHA). In overall, 35.7% were positive by both methods (combination) while 13.1% were RPR positive and TPHA negative, 8.7% were positive by TPHA only and 42.5% were negative by both methods. Among the RPR reactive (n = 246), 73.2% were positive by TPHA. Non-specific agglutination in RPR testing was relatively higher (26.8%) compared to TPHA (19.6%). Although TPHA was found more specific than RPR test, either of the single tests produced inaccurate diagnosis. Since the single RPR testing for syphilis may yield false positive results, specific treponemal test should be routinely used as confirmatory test to rule out false RPR positive cases. More attention needs to be paid on formulation of strict policy on the implementation of the existing guidelines throughout the country to prevent misdiagnosis in syphilis with the use of single RPR test.

    To examine the distribution of chlamydia, gonorrhoea and syphilis in the USA through the use of Lorenz curves and Gini coefficients. The distribution of three sexually transmitted diseases (STD; chlamydia, gonorrhoea and primary and secondary syphilis) was examined across states and counties in the USA in 2007, based on reported case numbers. Gini coefficients, which can range from 0 (equality in STD rates across geographical units) to 1 (complete inequality such that all STD occur in one geographical unit) were calculated. Overall, chlamydia was the most evenly distributed and syphilis was the most concentrated of the three STD examined. The Gini coefficients for chlamydia, gonorrhoea and syphilis were 0.121, 0.255 and 0.334, respectively, when examined across states, and 0.319, 0.494 and 0.630, respectively, when examined across counties. Differences in Gini coefficients were observed when the STD distributions were examined by sex, race/ethnicity and age group. The use of Lorenz curves and Gini coefficients can help to assess inequalities in the distribution of STD, to gauge the suitability of geographically targeted interventions, and to help in determining the epidemic phase of STD. Having a better understanding of the disparities in the distribution of STD across states and counties by sex, race/ethnicity and age group might help in understanding why disparities in STD rates exist across different groups and in developing interventions to address these disparities.

    To identify the population group in which syphilis increase was concentrated. The information was collected from the Mexico health statistical yearbooks. The information disaggregated by sex, age group and state during the period 2003 to 2013 was used to form different databases. Linear regression analysis with confidence interval at 95% was used to evaluate changes over time in different population groups. An increase of 0.67 cases per 100,000 population (95%CI 0.30-1.04) in men was detected from 2010. The increase was concentrated in each group of 20-24 and 25-44. The highest incidence of acquired syphilis was reported in the last two years: 2012 and 2013. The last year reported a 1.85 times higher incidence than reported in 2003. Aguascalientes, Distrito Federal, Durango, Mexico, Oaxaca, Puebla, Quintana Roo, Yucatan and Zacatecas reported that syphilis increased during the study period. Acquired syphilis may be reemerging in our country among young men; this increase is not uniform across the country, it is necessary to focus intervention measures for this sexually transmitted infection.

    Transfusion Transmissible Infections (TTIs) such as Human Immunodeficiency Virus (HIV), syphilis, hepatitis B virus (HBV) and hepatitis C virus (HCV) are infections which are common in some communities in Southern Africa. It is important to screen blood donations for these infections. This is a retrospective study which involved reviewing of previous blood donation records for the year 2012 in Namibia. The records were analyzed to determine the prevalence of HIV, syphilis, Hepatitis B and C among blood donations with regard to gender, age and geographical region of the donors. The findings indicated a significantly low prevalence of HIV, syphilis, HBsAg and anti-Hepatitis C among the blood donations. A low infection rate of 1.3% by any of the four tested TTIs was found among the blood donations given by the donor population in Namibia in 2012. The blood donations given by the donor population in Namibia has a low infection rate with the HIV, syphilis, HBsAg and anti-HCV. A strict screening regime must continue to be used as the infections are still present albeit in small numbers.

    Ulcer material from consecutive patients attending clinics in Antananarivo, Madagascar, was tested using multiplex polymerase chain reaction (M-PCR) to detect Treponema pallidum, Haemophilus ducreyi, and herpes simplex virus. Sera were tested for syphilis and for IgG and IgM antibodies to Chlamydia trachomatis by microimmunofluorescence testing (MIF). By M-PCR, 33% of 196 patients had chancroid, 29% had syphilitic ulcers, and 10% had genital herpes; 32% of the ulcer specimens were M-PCR negative. Compared with M-PCR, syphilis serology was 72% sensitive and 83% specific. The sensitivity of clinical diagnosis of syphilis, chancroid, and genital herpes was 93%, 53%, and 0% and specificity was 20%, 52%, and 99%, respectively. Less schooling was associated with increased prevalence of syphilitic ulcers (P=.001). Sixteen patients (8%) were clinically diagnosed with lymphogranuloma venereum (LGV); 1 plausible case of LGV was found by MIF. In Madagascar, primary care of genital ulcers should include syndromic treatment for syphilis and chancroid.

    One-step lateral flow test is recommended as the first line screening of syphilis for primary healthcare settings in developing countries. However, it generally shows low sensitivity. We describe here the development of a novel fluorescent POC (Point Of Care) test method to be used for screening for syphilis. The method was designed to combine the rapidness of lateral flow test and sensitiveness of fluorescent method. 50 syphilis-positive specimens and 50 healthy specimens conformed by Treponema pallidum particle agglutination (TPPA) were tested with Quantum Dot-labeled and colloidal gold-labeled lateral flow test strips, respectively. The results showed that both sensitivity and specificity of the quantum dots-based method reached up to 100% (95% confidence interval [CI], 91-100%), while those of the colloidal gold-based method were 82% (95% CI, 68-91%) and 100% (95% CI, 91-100%), respectively. In addition, the naked-eye detection limit of quantum dot-based method could achieve 2 ng/ml of anti-TP47 polyclonal antibodies purified by affinity chromatography with TP47 antigen, which was tenfold higher than that of colloidal gold-based method. In conclusion, the quantum dots were found to be suitable for labels of lateral flow test strip. Its ease of use, sensitiveness and low cost make it well-suited for population-based on-the-site syphilis screening.

    Syphilis is an important cause of morbidity in sub-Saharan Africa, and a cofactor for the sexual transmission of HIV. A better understanding of the prevalence and risk factors of syphilis in African populations would help to formulate effective interventions for its prevention and treatment. The prevalence and incidence of syphilis were obtained from a cohort recruited in Mwanza, Tanzania. Two unmatched case-control studies nested within the cohort provide information on potential risk factors. The prevalence of active syphilis (TPHA positive and RPR positive any titre) was 7.5% in men and 9.1% in women, but in youths (aged 15-19 years) the prevalence was higher in women (6.6%) than in men (2.0%). The incidence of TPHA seroconversion was highest in women aged 15-19 at 3.4% per year, and around 2% per year at all ages among men. A higher prevalence of syphilis was found in those currently divorced or widowed (men: OR=1.61, women: OR=2.78), and those previously divorced or widowed (men: OR=1.51, women: OR=1.85). Among men, prevalence was associated with lack of circumcision (OR=1.89), traditional religion (OR=1.55), and reporting five or more partners during the past year (OR=1.81) while incidence was associated with no primary education (OR=2.17), farming (OR=3.85), and a self perceived high risk of STD (OR=3.56). In women, prevalence was associated with no primary education (OR=2.13), early sexual debut (OR=1.59), and a self perceived high risk of STD (OR=3.57), while incidence was associated with living away from the community (OR=2.72). The prevalence and incidence of syphilis remain high in this rural African population. More effort is needed to promote safer sexual behaviour, and to provide effective, accessible treatment. The high incidence of syphilis in young women calls for sexual health interventions targeted at adolescents.

    HIV and syphilis during pregnancy remain a public health concern especially in developing countries. Pregnant women attending antenatal clinics sites for the first time between September and December 2011 and who accepted to participate in the study were enrolled. The objective was to estimate the syphilis and HIV infection rate in this population. A study was conducted in 44 selected ANCs from 12 departments (5 urban and 7 rural). Pregnant women who accepted to participate in the study, attending selected sentinel ANCs sites for the first time between September and December 2011 were enrolled. To detect HIV antibodies, two consecutive ELISA assays were used (Genscreen Ultra HIV Ag/Ac, (BioRad, France) and Enzygnostic Intergral II (Siemens, GMBH, Marbug-Germany). In case of discordant results, the Western blot test II, HIV1 and 2 (Bio-Rad, Marne la Coquette, France) was used as the reference method. The RPR (Bio-Scan, Karnataka, India) test was performed to detect syphilis infection. The RPR positive results were confirmed using the TPHA test (Biotech, Cambridge, UK). Data were analyzed using SPSS 17.0 software. A total of 2979 pregnant women attending ANCs were enrolled. The global HIV infection rate was estimated to be 3.6% (CI: 95%; 3.0-4.4). As expected, HIV prevalence was significantly higher in women aged above 25 years (4.4% (3.4-5.6), p = 0.026) and those attending urban ANCs (5.04%, p pregnant women (3.92%). The risk for syphilis occurrence was significantly higher among the single women compared to the married ones (4.4% VS 2.7%; p HIV and syphilis coinfection occurred in 22 cases (0.73%). The prevalence's of syphilis and HIV were relatively low. Marital status and sentinel site location were a risk factor associated with HIV and syphilis infections respectively. Therefore, substantial effort is needed to reinforce prevention strategies in this population to prevent mother-to-child and further horizontal transmissions of these infections.

  18. Antigenic variation of TprK facilitates development of secondary syphilis.

    Although primary syphilis lesions heal spontaneously, the infection is chronic, with subsequent clinical stages. Healing of the primary chancre occurs as antibodies against outer membrane antigens facilitate opsonophagocytosis of the bacteria by activated macrophages. TprK is an outer membrane protein that undergoes antigenic variation at 7 variable regions, and variants are selected by immune pressure. We hypothesized that individual TprK variants escape immune clearance and seed new disseminated lesions to cause secondary syphilis. As in human syphilis, infected rabbits may develop disseminated secondary skin lesions. This study explores the nature of secondary syphilis, specifically, the contribution of antigenic variation to the development of secondary lesions. Our data from the rabbit model show that the odds of secondary lesions containing predominately TprK variant treponemes is 3.3 times higher than the odds of finding TprK variants in disseminated primary lesions (odds ratio [OR] = 3.3 [95% confidence interval {CI}, 0.98 to 11.0]; P = 0.055) and that 96% of TprK variant secondary lesions are likely seeded by single treponemes. Analysis of antibody responses demonstrates significantly higher antibody titers to tprK variable region sequences found in the inoculum compared to reactivity to tprK variant sequences found in newly arising secondary lesions. This suggests that tprK variants escape the initial immune response raised against the V regions expressed in the inoculum. These data further support a role for TprK in immune evasion and suggest that the ability of TprK variants to persist despite a robust immune response is instrumental in the development of later stages of syphilis.

    Blood transfusion is one of the most important therapeutic options of life-saving intervention for recipients who are in diseased or non-diseased conditions with severe blood loss. However, it is associated with certain risks which can lead to adverse consequences that may cause acute or delayed complications and bring the risk of transfusion-transmissible infections including HIV, Hepatitis B & C and Syphilis. So, there might be a fatal risk instead of life saving. This paper aims to provide a comprehensive and reliable tabulation of available data on seroprevalence and diagnosis of HIV, HBV, HCV and Syphilis infections among blood donors. We searched studies reporting the prevalence rate of HIV, HBV, HCV and Syphilis infections among blood donors that were published between October 2009 and June 2016, using databases of PubMed, Scopus, MEDLINE, Elsevier, ScienceDirect, EBSCO, Google Scholar, EMBASE, and Web of Science with keywords: ``Hepatitis C Virus'', ``Hepatitis B Virus'', ``HIV'', ``Syphilis'', ``Seroprevalence'', and ``blood donor''. The seroprevalence of HBV and HCV was highest in African countries as compared to others continents, predominantly the West African region with a range of 10.0% to 14.96% and 1.5% to 8.69%, respectively, while the overall seropositivity of HIV and syphilis infection show a significant declining pattern through successive years globally, even though relatively higher prevalence rate was observed among older age and those with low level of education. There is a problem during selection, diagnoses and screening process in developing nations primarily due to shortage of sensitive screening test kits, highly qualified human resource and lack of proper standard operating procedures and hence, the safety of blood and blood products are the primary threats in the region. Proper clinical diagnosis and screening method should be applied during blood donation and therefore, all the donated blood should be screened properly for

  20. Syphilis Networks in Louisiana: An Analysis of Network Configuration and Disease Transmission

    Desmarais, Catherine Theresa

    Background: In 2009, Louisiana had the highest rate of primary and secondary syphilis in the country. Recent partner notification approaches have been insufficient in addressing Louisiana's deeply entrenched areas of syphilis infection. Prior researchers have suggested that surveillance systems may benefit from utilizing social and spatial network analysis in syphilis control efforts. Objective: To expand the understanding of the spread of syphilis in Louisiana, and to add new tools to the state's case finding resources through the description of the characteristics of cases of early syphilis and their partners in Louisiana, the socio-sexual networks of these cases, and the geospatial clustering of cases and partners. Methods: Utilizing state surveillance data, all cases of primary, secondary, and early latent syphilis that were diagnosed in 2009 and data on their sexual or needle sharing partners were analyzed using a combination of descriptive, network, and geospatial measures. Results: In 2009, Louisiana experienced a high rate of heterosexual syphilis transmission. Within syphilis transmission networks, 50.8% of all cases were female and 84.2% of all cases were black. The average and median ages of males with reactive syphilis tests were higher than that of females in Louisiana, and in 88.9% of regions, older individuals were more likely to have a syphilis test than no test. A greater proportion of males (11.4%) refused to discuss partners than females (7.4%) and a greater proportion of males (5.5%) refused testing and prophylactic treatment than females (2.8%). No distinct patterns were seen in disease prevalence between regions based upon demographic data. Classic summary network measures such as density, degree, centrality, and betweenness provided little information on similarities and differences between the different regions in Louisiana. All measures indicated low density and extreme fragmentation of networks in Louisiana. The majority of network

    Repeat syphilis is playing an increasing role in syphilis transmission in several populations. The assessment of repeat syphilis and response to treatment depends on accurately measuring intraindividual changes in non-treponemal tests. For a 0- to 6-month delta rapid plasma reagin (RPR) to be determined by routine individual RPR testing, samples are tested 6 months apart with differences in reagent batches, environmental conditions, and observers all leading to measurement errors. We hypothesized that conducting paired RPR testing (simultaneous testing of acute and convalescent samples) would enable a more accurate determination of delta RPR compared with individual testing. A total of 120 study participants with a new diagnosis of syphilis were followed up at 0, 3, 6, 9, 12, 18, and 24 months, with RPR testing performed via individual testing at each study visit and at any suspected repeat syphilis. Rapid plasma reagin paired testing was performed on samples from 0 and 6 months and at any suspected repeat syphilis. The quantitative agreement ±1 dilution among paired and individual testing was 97.2%. There was no difference in the proportion with serofast status at 6 months: 21 (19.4%) and 19 (17.6%) according to paired and individual testing, respectively (P = 0.726). There was no statistically significant difference between 0- and 6-month delta RPR as determined by paired and individual testing in predicting seroresponse at 12 months (86.1% and 91.6% agreement with 12-month serofast/nonserofast classification, respectively; P = 0.262). In our setting, individual testing performed equally well compared with paired testing. Follow-up of syphilis will remain onerous for the patient and the health care provider until new tests that can more accurately assess the response to therapy and repeat syphilis/treatment failure are developed.

    Full Text Available From the data submitted to the Pan American Health Organization (PAHO by nationwide programs against sexually transmitted diseases (STD, HIV infection, and AIDS (2002, one can estimate the overall prevalence of syphilis among pregnant women to be 3.1% and to range from 1.00% in Peru to 6.21% in Paraguay. According to these data, the incidence of congenital syphilis ranges from 1.4 per 1 000 live births in El Salvador to 12.0 per 1 000 live births in Honduras. Among men who engage in sex with other men, who often classify themselves as heterosexual, as well as in female sex workers, the prevalence of syphilis ranged from 5% to 15%. Factors that determine the persistence of congenital syphilis as a public health problem include a lack of awareness of the seriousness of the problem among politicians, health officials, and health care providers, difficult access to prenatal care and screening services, a low demand for the test among users, and the stigma and discrimination that surround sexually transmitted diseases (STD. This paper seeks to focus the attention of health professionals on maternal and congenital syphilis so they will undertake actions, using an interprogrammatic approach, to eliminate congenital syphilis from Latin America and the Caribbean. Eliminating congenital syphilis will only become possible if interventions targeting vulnerable groups are also implemented. PAHO's role in eliminating congenital syphilis includes determining the baseline situation in the Region as a whole and in each country, developing communication and procurement strategies, supporting nationwide programs, promoting operational research, and facilitating interprogrammatic coordination.

    BACKGRAUND. Treponemal tests based on the detection of antibodies against the Treponema pallidum antigens are the most specific methods for serological diagnosis of syphilis. Due to the inability to cultivate this bacterium in vitro, the most promising sources of antigens for diagnostics are recombinant proteins of T. pallidum. Evaluation of the analytical value of certain T. pallidum proteins is the approach to improve sensitivity, specificity, and reproducibility of syphilis serological tests, including possibilities of differential diagnosis of various forms of the disease. The aim of the research was to evaluate the analytical values (sensitivity and specificity) of recombinant protein Tp0965 of T. pallidum as a candidate antigen for serological diagnosis of syphilis. tp0965 gene was cloned into the expression vector pET28a and the construct was used for the transformation of E. coli BL-21 (DE3) cells and further expression and purification of the recombinant protein. The collected protein was used as T. pallidum antigen for serum analysis (ELISA) of groups of patients with various forms of syphilis (n=84) and the group of healthy donors (n = 25). High frequency of positive ELISA results was shown with serum of patients with syphilis, compared to the group of healthy donors. The sensitivity of serological reactions using recombinant protein Tp0965 was 98.8%, specificity--87.5%. The highest sensitivity (100%) was detected in the groups of patients with primary, secondary and early latent syphilis while in the group of patients with late latent syphilis it decreased to 95.2%. We concluded that due to its specificity T. pallidum recombinant protein Tp0965 can be used as a novel perspective antigen for development of syphilis serological diagnostic assays (for primary and early latent forms).

    Sexually transmitted infections (STIs) are a serious public health problem in low income countries, including Ethiopia. Syphilis caused by Treponema pallidum remains a major cause of reproductive morbidity and poor pregnancy outcomes in low income countries. Stillbirth, perinatal death, serious neonatal infection and low-birth weight babies are common among seropositive mothers. To assess the seroprevalence of syphilis and risk factor correlates of this infection at Gondar University Teaching Hospital, Ethiopia. The study was done on 2385 pregnant women attending the antenatal care clinic (ANC) from January 2009 to December 2011. Data was abstracted from the antenatal care clinic medical database. Chi-square test was used, using SPSS version 16 and significance level was chosen at 0.05 level with a two-tailed test. Of the total, 69(2. 9%) of pregnant women were confirmed as seropositive for syphilis. Pregnant women with an age group of 21-25 years of old were the most seropositive (3.4%), followed by 26-30 years of old (3.1%). The prevalence of syphilis infection was 3.2% in urban and 2.2% in rural pregnant women. Relatively high prevalence of syphilis infection were identified among students (4.2%) followed by governmental employees (3.8%). The seroprevalence of syphilis among pregnant women attending ANC is declining. However, syphilis is more prevalent in the young and urban pregnant women. Emphasis on education to young people on STI risk behavioral change and partner follow up and notification for exposure to syphilis and treatment should be given.

    Syphilis has made a rapid resurgence in China, especially among high-risk groups including female sex workers (FSWs). Two cities in each of 3 provinces in South China were chosen and allocated to intervention or control arms. The intervention consisted of enhancing community-based syphilis screening outreach intervention with comprehensive sexually transmitted infection services at designated clinics while the control maintained routine intervention activities. Generalized linear modeling was used to examine effect of the intervention on incident syphilis infection. A total of 8275 women were eligible, and 3597 women enrolled (n = 2011 in control arm, n = 1586 in intervention arm) in the study. The median follow-up duration was 375 days (interquartile range, 267–475). Syphilis incidence density in the intervention group was reduced by 70% (95% confidence interval, 53%–81%) compared with the incidence in the control arm. The syphilis prevention intervention benefits were robust among FSWs at low-tier venues, individuals with less than high school education, migrants, and women who did not report condom use during the last episode of sex. Integrated sexually transmitted infection and human immunodeficiency virus prevention strategies substantially reduce syphilis incidence among FSWs, especially among those at low-tier venues. This intervention suggests the need for scaling up comprehensive FSW programs in China.

    Reverse sequence screening for syphilis, in which an automatable treponemal assay (enzyme immunoassay [EIA]/chemiluminescence assay [CIA]) is performed first and followed by a nontreponemal test for reactive specimens, has been used increasingly in the United States. The EIA is objective, efficient, and believed to be more sensitive than the rapid plasma reagin (RPR) because treponemal antibodies appear before nontreponemal antibodies. We sought to compare the sensitivity of a commonly used EIA, the Trep-Sure EIA (TS-EIA), to the RPR in cases of suspected primary syphilis infection in our clinic. A retrospective medical record review of patients with sexually transmitted infection clinic visits from January 2009 to December 2011 was conducted, and 52 patients met the following inclusion criteria: suspected primary syphilis symptoms, at least 1 positive syphilis test result at visit, and no history of syphilis. Sensitivity analyses compared the TS-EIA and RPR, using the reference standard of concordantly positive/reactive TS-EIA/RPR or positive fluorescent treponemal antibody absorption test (FTA-ABS) result. We considered equivocal TS-EIA results to be positive for sensitivity calculations because such results typically reflex to additional testing and therefore may still result in identifying new infections. Twenty-eight (53.8%) of the 52 patients had a positive or equivocal TS-EIA. Twenty-five (89.3%) of those were RPR reactive; the remaining 3 (10.7%) were RPR nonreactive, FTA-ABS positive. Forty patients (76.9%) had a positive RPR, including 15 patients (37.5%) with negative TS-EIA results; all 15 were FTA-ABS positive. Nine additional patients were TS-EIA negative and RPR nonreactive but had a positive FTA-ABS result. The RPR was significantly more sensitive than the EIA (76.9% vs. 53.8%, P = 0.005). Trep-Sure EIA positivity was also significantly associated with higher median RPR titer (P = 0.011). Use of the TS-EIA may result in underdetection of primary

    It is not known if there is a difference in the immune response to syphilis between HIV-infected and uninfected individuals. We prospectively recruited all patients with a new diagnosis of syphilis and tested their plasma for IFNα, IFNγ, IL-1β, IL-12p40, IL-12p70, IP-10, MCP-1, MIP-1α, MIP-1β, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10 and IL-17A at baseline pre-treatment and 6 months following therapy. A total of 79 HIV-infected [44 primary/secondary syphilis (PSS) and 35 latent syphilis (LS)] and 12 HIV-uninfected (10 PSS and 2 LS) cases of syphilis and 30 HIV-infected controls were included in the study. At the baseline visit, compared to the control group, concentrations of IL-10 were significantly elevated in the HIV-infected and uninfected groups. The level of IL-10 was significantly higher in the HIV-infected compared to the HIV-uninfected PSS group (25.3 pg/mL (IQR, 4.56-41.76) vs 2.73 pg/mL (IQR, 1.55-9.02), P = 0.0192). In the HIV-infected PSS group (but not the HIV-infected LS or HIV-uninfected PSS groups) the IP-10, MIP-1b, IL-6 and IL-8 were raised compared to the controls. IL-10 levels decreased but did not return to control baseline values by 6 months in HIV infected PSS and LS and HIV uninfected PSS. PSS and LS in HIV-infected individuals is characterized by an increase in inflammatory and anti-inflammatory cytokines such as IL-10. The increase of IL-10 is greater in HIV-infected than uninfected individuals. Further work is required to ascertain if this is part of an immunological profile that correlates with adverse outcomes such as serofast syphilis and neurosyphilis, in HIV-infected individuals.

    Full Text Available Since a proper diagnosis of syphilis is often difficult due to the wide variability of both clinical picture and laboratory test results, early recognition of infection caused by Treponema pallidum is crucial for a timely and effective treatment. In most cases, definitive diagnosis relies upon serological testing. A screening ELISA test, coupled with a quantitative RPR test and specific IgM antibodies detection, is currently regarded as the basic diagnostic procedure. In addition, a quantitative particle agglutination TP-PA test, FTA-abs IgG test and, eventually, a western-blot IgG and IgM test, allow to achieve a whole serological pattern for each patient at the time of first diagnosis. In this study, a group of serum samples (n=107 and cerebro-spinal fluid (n=3 were retrospectively analyzed using the above mentioned tests. A population of 19 patients whose clinical picture was unremarkable for syphilis, showed border-line values at screening and negative results on confirmation tests. Thirty-three out of 91 luetic patients were diagnosed as primary or early secondary syphilis, 36 as latent syphilis, 3 as neurosyphilis, and 3 were neonates with passive specific immunization. Quantitative RPR test and detection of specific IgM antibodies exhibited extremely high values in all 33 primary syphilis patients; a whole positive luetic pattern was also obtained by confirmation tests. Searching for IgM antibodies, a capture elisa test compared with a single device rapid elisa test showed an overall concordance of 98.1%. In luetic patients other than primary syphilis, quantitative RPR test and detection of specific IgM antibodies provided less relevant values and a low prevalence pattern, whereas TP-PA and FTA-abs tests showed persistent positives results. In the follow up of 19 initially treated patients, quantitative RPR values and specific IgM antibodies index showed a slow, progressive decrease until negative. Conclusion: a comprehensive initial

    Syphilis remains the most common congenital infection worldwide and has tremendous consequences for the mother and her developing fetus if left untreated. Recently, there has been an increase in the number of congenital syphilis cases in the United States. Thus, recognition and appropriate treatment of reproductive-age women must be a priority. Testing should be performed at initiation of prenatal care and twice during the third trimester in high-risk patients. There are 2 diagnostic algorithms available and physicians should be aware of which algorithm is utilized by their testing laboratory. Women testing positive for syphilis should undergo a history and physical exam as well as testing for other sexually transmitted infections, including HIV. Serofast syphilis can occur in patients with previous adequate treatment but persistent low nontreponemal titers (Syphilis can infect the fetus in all stages of the disease regardless of trimester and can sometimes be detected with ultrasound >20 weeks. The most common findings include hepatomegaly and placentomegaly, but also elevated peak systolic velocity in the middle cerebral artery (indicative of fetal anemia), ascites, and hydrops fetalis. Pregnancies with ultrasound abnormalities are at higher risk of compromise during syphilotherapy as well as fetal treatment failure. Thus, we recommend a pretreatment ultrasound in viable pregnancies when feasible. The only recommended treatment during pregnancy is benzathine penicillin G and it should be administered according to maternal stage of infection per Centers for Disease Control and Prevention guidelines. Women with a penicillin allergy should be desensitized and then treated with penicillin appropriate for their stage of syphilis. The Jarisch-Herxheimer reaction occurs in up to 44% of gravidas and can cause contractions, fetal heart rate abnormalities, and even stillbirth in the most severely affected pregnancies. We recommend all viable pregnancies receive the first

    Recently, a treponema-specific immunoglobulin G (IgG) enzyme immunoassay (EIA), the CAPTIA Syphilis-G (Trinity Biotech, Jamestown, N.Y.), has become available as a diagnostic test for syphilis. A total of 89 stored sera previously tested by the fluorescent treponemal antibody absorption (FTA-ABS) IgG assay were evaluated by the CAPTIA EIA. The FTA-ABS IgG procedure was performed by technologists unblinded to results of rapid plasmid reagin (RPR) testing of the same specimens. Borderline CAPTIA-positive samples (antibody indices of >/=0.650 and 0.900, the sample was considered positive. Thirteen of 89 (15%) samples had discrepant results. Compared to the FTA-ABS assay, the CAPTIA EIA had a sensitivity and specificity and positive and negative predictive values of 70.7, 97.9, 96.7, and 79.7%, respectively. In another analysis, discrepancies between results were resolved by repeated FTA-ABS testing (technologists were blinded to previous RPR results) and patient chart reviews. Seven CAPTIA-negative samples which were previously interpreted (unblinded) as minimally reactive by the FTA method were subsequently interpreted (blinded) as nonreactive. One other discrepant sample (CAPTIA negative and FTA-ABS positive [at an intensity of 3+], unblinded) was FTA negative with repeated testing (blinded). For the five remaining discrepant samples, chart reviews indicated that one patient (CAPTIA negative and FTA-ABS positive [minimally reactive], blinded) had possible syphilis. These five samples were also evaluated and found to be negative by another treponema-specific test, the Treponema pallidum microhemagglutination assay. Therefore, after repeated testing and chart reviews, 2 of the 89 (2%) samples had discrepant results; the adjusted sensitivity, specificity, and positive and negative predictive values were 96.7, 98.3, 96.7, and 98.3%, respectively. This study demonstrates that the CAPTIA IgG EIA is a reliable method for syphilis testing and that personnel performing tests

    Strengthening current surveillance systems for syphilis is important to track and monitor disease burden. We used routinely collected laboratory information to generate surveillance estimates for syphilis trends among women of reproductive age (12-49 years) in the Northern Cape Province, a high syphilis burden region (2003 [8.6%] to 2011 [3.8%]) in South Africa. We extracted records meeting inclusion criteria from the National Health Laboratory Service electronic database for the period 2003-2012. A total of 286,024 women were included in the analysis. Syphilis seropositivity decreased between 2003 (5.7%) and 2012 (1.8%); p trend = 0.001, which was largely consistent with findings reported in the annual national syphilis and HIV survey from 2003 (8.6%) to 2011 (3.8%). Annually for the period from 2003 to 2012 there was an approximate 14% reduction in the prevalence ratio of syphilis seroprevalence (PR = 0.86, 95% CI = 0.85-0.87, p syphilis seropositivity over this period. There were also declines in prevalence ratios for syphilis seropositivity for the various age groups for the period. This study shows that the national laboratory database in South Africa can be used as a complimentary surveillance tool to describe and understand trends in syphilis seroprevalence in South Africa.

    In Budapest at the end of the 19th century, visiting brothels was an important part of night life, including the risk of some venereal disease (v.d.) like syphilis, the in-vogue illness of the age. The expansion of prostitution could be explained with the continuous growth of economy and social development as a consequence of urbanization. Prostitution has grown in innumerable forms, levels and places in order to meet all requirements since this was the only tolerated form of sexuality "out of homes". The police headquarters' duty was to control the observation of rules prescribed for prostitutes. Data and information were available only on registered "professional" prostitutes because references on hidden prostitution were hard to find. Liberalization of the strict rules and regalements on brothels and "staff" began at the time when the increase of prostitution and simultaneously, of syphilis overreached the capacity of the Police and the Health Care System.

    Full Text Available To estimate probability of adverse pregnancy outcomes (APOs among women with and without syphilis through a systematic review of published literatures.Chinese and English literatures were searched for studies assessing pregnancy outcomes in the presence of maternal syphilis through August 2013. The prevalence estimates were summarized and analyzed by meta-analysis. Fifty-four literatures involving 11398 syphilitic women and 43342 non-syphilitic women were included from 4187 records initially found. Among untreated mothers with syphilis, pooled estimates were 76.8% for all APOs, 36.0% for congenital syphilis, 23.2% for preterm, 23.4% for low birth weight, 26.4% for stillbirth or fetal loss, 14.9% for miscarriage and 16.2% for neonatal deaths. Among syphilitic mother receiving treatment only in the late trimester (>28 weeks, pooled estimates were 64.4% for APOs, 40.6% for congenital syphilis, 17.6% for preterm, 12.4% for low birth weight, and 21.3% for stillbirth or fetal loss. Among syphilitic mothers with high titers (≥1∶8, pooled estimates were 42.8% for all APOs, 25.8% for congenital syphilis, 15.1% for preterm, 9.4% for low birth weight, 14.6% for stillbirth or fetal loss and 16.0% for neonatal deaths. Among non-syphilitic mothers, the pooled estimates were 13.7% for all APOs, 7.2% for preterm birth, 4.5% for low birth weight, 3.7% for stillbirth or fetal loss, 2.3% for miscarriage and 2.0% for neonatal death. Begg's rank correlation test indicated little evidence of publication bias (P>0.10. Substantial heterogeneity was found across studies in the estimates of all adverse outcomes for both women with syphilis (I2 = 93.9%; P<0.0001 and women without syphilis (I2 = 94.8%; P<0.0001.Syphilis continues to be an important cause of substantial perinatal morbidity and mortality, which reminds that policy-makers charged with resource allocation that the elimination of mother-to-child transmission of syphilis is a public health priority.

    The incidence of HIV and syphilis among men who have sex with men (MSM) in Europe has recently increased. Rapid point-of-care tests (POCTs) for syphilis can improve access to screening. The purpose of this study was to evaluate the performance of two syphilis POCTs compared with laboratory tests among MSM. The study was undertaken in Verona, Italy. Asymptomatic MSM, potentially exposed to syphilis, were enrolled prospectively. The POCTs evaluated were SD Bioline Syphilis 3.0 and Chembio DPP Syphilis Screen & Confirm Assay on both serum and fingerprick blood. The results of the POCTs were read by the naked eye by two independent readers and their concordance assessed. A total of 289 MSM were enrolled in the study. Based on laboratory tests, 35 MSM (12.1%) were TPPA-positive alone and 16 (5.5%) were both Treponema pallidum particle agglutination test (TPPA) and rapid plasma reagin (RPR)-positive. The specificities of both POCTs were above 99% on both serum and fingerstick blood specimens, while sensitivities varied considerably. The sensitivity of the SD Bioline test was lower on fingerprick blood (51.4% and 54.3%, readers 1 and 2, respectively) compared with that on serum (80.0% and 82.9%). In contrast, the Chembio test exhibited similar sensitivity values for serum and fingerprick samples (57.7% and 64.0% on serum vs 65.4% and 69.2% on fingerprick for the treponemal component; 63.6% on both samples by both readers for the non-treponemal component). The positive predictive value ranged between 100% and 93.9% for the treponemal component of both syphilis POCTs, but was lower (76.3%-100%)%) for the non-treponemal component of the Chembio POCT. The negative predictive value surpassed 90% for both tests on both samples. The agreement between readers was very high (>99%). The diagnostic performance of the syphilis POCTs was lower than expected; however, considering the prevalence of syphilis among MSM, POCTs should be recommended to improve syphilis detection among MSM

HDP 99m Tc bone scintigraphy showed increased uptake around the right sacro-iliac joint and in the right iliac area due to increased osteoblastic activity, thereby providing functional information about the evolutive nature of the bone lesion. The X-scanner only revealed osteolysis in the same location. A blood test confirmed the diagnosis of tertiary syphilis. (author)

    Although primary syphilis lesions heal spontaneously, the infection is chronic, with subsequent clinical stages. Healing of the primary chancre occurs as antibodies against outer membrane antigens facilitate opsonophagocytosis of the bacteria by activated macrophages. TprK is an outer membrane protein that undergoes antigenic variation at 7 variable regions, and variants are selected by immune pressure. We hypothesized that individual TprK variants escape immune clearance and seed new dissemi...

    Serologic tests are widely used for the diagnosis of syphilis. However, conventional methods require well-trained technicians to produce reliable results. We compared automated nontreponemal and treponemal tests with conventional methods. The HiSens Auto Rapid Plasma Reagin (AutoRPR) and Treponema Pallidum particle agglutination (AutoTPPA) tests, which utilize latex turbidimetric immunoassay, were assessed. A total of 504 sera were assayed by AutoRPR, AutoTPPA, conventional VDRL and FTA-ABS. Among them, 250 samples were also tested by conventional TPPA. The concordance rate between the results of VDRL and AutoRPR was 67.5%, and 164 discrepant cases were all VDRL reactive but AutoRPR negative. In the 164 cases, 133 showed FTA-ABS reactivity. Medical records of 106 among the 133 cases were reviewed, and 82 among 106 specimens were found to be collected from patients already treated for syphilis. The concordance rate between the results of AutoTPPA and FTA-ABS was 97.8%. The results of conventional TPPA and AutoTPPA for 250 samples were concordant in 241 cases (96.4%). AutoRPR showed higher specificity than that of VDRL, while VDRL demonstrated higher sensitivity than that of AutoRPR regardless of whether the patients had been already treated for syphilis or not. Both FTA-ABS and AutoTPPA showed high sensitivities and specificities greater than 98.0%. Automated RPR and TPPA tests could be alternatives to conventional syphilis tests, and AutoRPR would be particularly suitable in treatment monitoring, since results by AutoRPR in cases after treatment became negative more rapidly than by VDRL.

    To determine prevalence of and risk factors associated with HIV and syphilis seropositivity and estimate incidence of HIV infection among Peruvian men who have sex with men (MSM) and characterize behaviors of men who report sex with both men and women ('bridgers'). Cross-sectional study of MSM in Lima, Peru. Four-hundred and fifty-one MSM (of whom 442 responded to the question regarding sexual orientation) recruited through street outreach. Each was interviewed and underwent serologic testing for syphilis and HIV, including the less sensitive enzyme immunoassay test to estimate HIV incidence. Overall, HIV and syphilis prevalence were 18.5% and 16.0%, respectively, with highest prevalence among cross-dressers (33.3% and 51.1%, respectively). The estimated overall HIV seroincidence was 11.2% per year (95% confidence interval, 4.8-23.6). Overall, 47.1% of men reported ever having sex with a woman: 78.6% of men self-identifying as heterosexuals, 85.1% of bisexuals, 35.5% of homosexuals, and 12.5% of cross-dressers. Of these, 26.5% were 'bridgers', of whom 55% reported two or more female partners during the last year. 'Bridgers' were less likely to have always used condoms during the past year for vaginal sex (17%) than for insertive anal sex with men (25.5%). Among MSM in Peru, HIV and syphilis prevalence and HIV incidence were high, especially among cross-dressers. The high prevalence of bisexuality and low rates of consistent condom use, especially with female sexual partners indicates potential HIV transmission into the heterosexual population.

    Syphilis is a major concern to global public health with increasing incidence. So its screening test should have sufficient sensitivity and specificity. We evaluated the performance of the Lumipulse G TP-N assay detection for syphilis screening and compared it with the InTec ELISA test kit for TP, which is widely used. Samples of several patient groups including 133 clinical and serologically characterized syphilitic sera, 175 samples containing potentially interfering agents, and 2290 unselected samples submitted for routine screening were detected by both the Lumipulse G TP-N assay and the InTec ELISA test kit for TP. Inconsistent samples were confirmed by RecomLine Treponema IgG, IgM immunoblot. Coefficient of variations of the Lumipulseo G TP-N assay at both levels were below 5% and of the InTec ELISA test kit for TP both over 5%. The sensitivity of the Lumipulse G TP-N assay and the InTec ELISA test kit for TP were 100% for all stages of syphilis. The two methods had consistent analytical specificity of 100% (95% CI: 97.21 - 100.00), while the clinical specificity was 100% (95% CI: 99.79 - 100.00) and 99.82% (95% CI: 99.51 - 99.94), respectively. Between them, Spearman's correlation coefficient was 0.455 and kappa value was 0.986. The overall sensitivity and specificity of the Lumipulse G TP-N assay was higher than the InTec ELISA test kit for TP (sensitivity: 100.0 versus 99.5, specificity: 100.0 versus 99.8). The automated Lumipulse G TP-N assay demonstrated excellent diagnostic sensitivity and specificity when evaluated as a screening test for syphilis. Thus, it can be an alternative to the treponemal screening test.

    To describe the clinical course and prognosis of ocular syphilis in patients infected with HIV-1 in the antiretroviral therapy (ART) era. We conducted a single-centre retrospective chart review of ocular syphilis in patients infected with HIV-1 diagnosed between August 1997 and July 2015. The prognosis of best-corrected visual acuity (BCVA) was analysed. The study subjects were 30 eyes of 20 men who had sex with men (MSM) (median age, 41). Loss of vision and posterior uveitis were the most common ocular clinical features (43%) and location of inflammation at presentation (50%), respectively. The median baseline BCVA was 0.4 (IQR 0.2-1.2), including three eyes with hand motion. BCVA≤0.4 at diagnosis was significantly associated with posterior uveitis or panuveitis (p=0.044). Seventy-five per cent were treated with intravenous benzylpenicillin and 53% were diagnosed with neurosyphilis. After treatment (median follow-up: 21 months), BCVA improved in 89% of the eyes, including all eyes with hand motion, to a median BCVA of 1.2 (IQR 0.8-1.2). Kaplan-Meier analysis showed that >28 days of ocular symptoms before diagnosis was the only factor associated with poor prognosis of BCVA. Three patients (15%) developed recurrence after treatment. The prognosis of BCVA in HIV-infected patients with ocular syphilis in the ART era was favourable after proper treatment. Having >28 days of ocular symptoms before diagnosis was associated with poor prognosis. Changes in visual acuity in HIV-infected MSM should prompt an immediate assessment for ocular syphilis as delays in diagnosis and therapy can lead to irreversible visual loss.

    Two adult cases, one of secondary syphilis and one of Listeria monocytogenes bacteremia, in which antibiotic desensitization therapy was utilized to assist treatment of active infection in the face of severe penicillin allergy. Clinical considerations are discussed that led to the decision to employ a formal desensitization procedure. Antibiotic desensitization protocols can facilitate optimal and safe antibiotic therapy in the appropriate clinical setting. PMID:22187514

    Full Text Available Three recombinant antigens of Treponema pallidum Nichols strain were fused with GST, cloned and expressed in Escherichia coli, resulting in high levels of GST-rTp47 and GST-rTp17 expression, and supplementation with arginine tRNA for the AGR codon was needed to obtain GST-rTp15 overexpression. Purified fusion protein yields were 1.9, 1.7 and 5.3 mg/l of cell culture for GST-rTp47, GST-rTp17 and GST-rTp15, respectively. The identities of the antigens obtained were confirmed by automated DNA sequencing using ABI Prism 310 and peptide mapping by Finningan LC/MS. These recombinant antigens were evaluated by immuno-slot blot techniques applied to 137 serum samples from patients with a clinical and laboratory diagnosis of syphilis (61 samples, from healthy blood donors (50 samples, individuals with sexually transmitted disease other than syphilis (3 samples, and from individuals with other spirochetal diseases such as Lyme disease (20 samples and leptospirosis (3 samples. The assay had sensitivity of 95.1% (95% CI, 86.1 to 98.7% and a specificity of 94.7% (95% CI, 87.0 to 98.7%; a stronger reactivity was observed with fraction rTp17. The immunoreactivity results showed that fusion recombinant antigens based-immuno-slot blot techniques are suitable for use in diagnostic assays for syphilis.

    Interpret perceptions of Colombian health professionals concerning factors that obstruct and facilitate the introduction of rapid syphilis and HIV testing in prenatal care services. A qualitative study based on semi-structured interviews was carried out. A convenience sample was selected with 37 participants, who included health professionals involved in prenatal care services, programs for pregnant women, clinical laboratories, and directors of health care units or centers, as well as representatives from regional departments and the Ministry of Health. Colombia does not do widespread screening with rapid syphilis and HIV tests in prenatal care. The professionals interviewed stated they did not have prior experience in the use of rapid tests-except for laboratory staff-or in the course of action in response to a positive result. The insurance system hinders access to timely diagnosis and treatment. Health authorities perceive a need to review existing standards, strengthen the first level of care, and promote comprehensive prenatal care starting with contracts between insurers and health service institutional providers. Participants recommended staff training and integration between health-policymaking and academic entities for updating training programs. The market approach and the characteristics of the Colombian health system constitute the main barriers to implementation of rapid testing as a strategy for elimination of mother-to-child transmission of syphilis and HIV. Measures identified include making changes in contracts between insurers and health service institutional providers, adapting the timing and duration of prenatal care procedures, and training physicians and nurses involved in prenatal care.

    In the last few years, Malta has witnessed increasing immigration flows from the Libyan coasts. Public health policies are focused on screening migrants for tuberculosis, whereas no systematic actions against STIs are implemented. The aim of this study is to define the epidemiological profile of asylum seekers in Malta as regards syphilis, hepatitis B, C and latent tuberculosis, thus supporting screening policies. Five hundred migrants living in open centres were screened between December 2010 and June 2011. 83.2% of people was from Somalia, 81.2% males, average age 26.5 years. The tuberculin skin test (TST) was positive in 225 migrants (45%). Latent syphilis was diagnosed in 11 migrants, hepatitis C in 3 and 31 migrants were HBsAg positive. Systematic screening for asymptomatic migrants in Malta is not recommended for hepatitis C and syphilis, given the low prevalence observed. On the contrary, it should be considered for hepatitis B. TST could be indicated as the first step of a two step screening for migrants from countries with high TB incidence. Efficacy and cost-effectiveness could be achieved by further targeting screening to specific subgroups at higher risk of reactivation, such as people living with HIV and subjects affected by chronic diseases.

    Full Text Available The aim of this study was to investigate the prevalence of syphilis and associated factors in inmates of the women's prison of Teresina, Piauí, Brazil. This cross-sectional study was conducted in November 2013. The population consisted of inmates from the referred penitentiary (n=131. Data were collected through a form composed of closed-ended and mixed questions. The mean age was 33.1 years, 60.3% affirmed not having a stable relationship, and 93.1% had children. Alcohol use was reported by 70.8%, and the use of illicit drugs, by 56.2%. It was evidenced that 38.5% of women never use a condom during sexual intercourse, and that 62.2% do not know how the transmission of syphilis happens. The high prevalence of syphilis, 25.2%, is statistically associated with marital status, illicit drug use and their consumption before sex, demonstrating that unfavorable socioeconomic conditions are important risk and vulnerability factors to sexually transmitted diseases.

    Guyana had an estimated HIVprevalence of 1.5% among pregnant women in 2006 (95% confidence interval [CI] = 1.1-1.9). However, a survey of miners in one mine found a 6.5% HIV prevalence in 2002. To determine whether Guyanese miners are at high risk for HIV infection we conducted a HIV and syphilis prevalence survey of miners in several mines. Adult male consenting miners in 45 Guyanese mines were interviewed, counselled, tested for HIV and syphilis with rapid tests and provided onsite test results. The survey was cross-sectional and used a multi-stage cluster sampling design; population estimates were calculated using SUDAAN. Of 651 miners approached, 539 (83%) were interviewed and 509 (78%) tested. The estimated prevalence for HIV was 3.9% (CI = 2.1, 7.1) and for life-time syphilis exposure was 6.4% (CI = 4.5, 9.1). Fifty-four per cent (CI = 41.3, 66.7) of miners had casual sex during the preceding year, of whom 44.4% (CI = 34.3, 55.0) had always used condoms with these partners. The estimated HIV prevalence among Guyanese miners was higher than that of the general population. Targeted interventions including condom promotion are recommended to prevent further spread of HIV and other sexually transmitted infections among miners.

    INTRODUCTION. There are many forms of neuro-ophthalmological involvement secondary to syphilis, and not all of them are well known. Our aim is to determine the clinical and therapeutic differences in these patients. CASE REPORTS. Our sample included eight patients diagnosed with an ocular and neuro-ophthalmological disorder due to syphilis over the years 2012 and 2013. Five of them presented uveitis, pan-eveitis being the most frequent, with three cases. Two cases presented papilloedema and another displayed retrobulbar optic neuropathy. A total of 62.5% were diagnosed with neurosyphilis, the presence of which was related with compromise of the optic nerve (p = 0.035). None of them gave positive for VDRL in cerebrospinal fluid and they were diagnosed by the presence of FTA antibodies together with high protein levels in cerebrospinal fluid, lymphocytic pleocytosis or intrathecal synthesis of antibodies. In the absence of uveitis, diagnosis was delayed by a mean time of 2.6 months (p = 0.047). All the patients, except one who required a vitrectomy, progressed favourably with intravenous antibiotic therapy. CONCLUSIONS. In cases of neuro-ophthalmological compromise, whether inflammatory or non-inflammatory, the physician must bear syphilis in mind as a potential causation in order to avoid delays in the diagnosis, since early well-tailored treatment can prevent permanent loss of sight.

    To analyse the dental remains of an individual with signs of congenital syphilis by using macroscopic observation, CBCT and micro-CT images, and the analysis of the enamel thickness. Anthropological analysis of human skeletal remains from the 16th century archaeological site Park Grič in Zagreb, Croatia discovered a female, 17-20 years old at the time of death, with dental signs supportive of congenital syphilis: mulberry molars and canine defects, as well as non-specific hypoplastic changes on incisors. The focus of the analysis was on three aspects: gross morphology, hypoplastic defects of the molars, canines and incisors, as well as enamel thickness of the upper first and second molars. The observed morphology of the first molars corresponds to the typical aspect of mulberry molars, while that of the canines is characterised by hypomineralisation. Hypoplastic grooves were observed on the incisal edges of all incisors. The enamel of the first molars is underdeveloped while in the second molars a thick-enamelled condition is observed. Our observations for the dental and skeletal evidence are supportive to a diagnosis of congenital syphilis for this specimen from XVI century Croatia. The use of CT imaging helped documenting the diagnostic features and quantifying the effect of the dental stigmata on first molars. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Frequency of syphilis among pregnant women attending Combined Military Hospital Abbottabad Study Design: Descriptive study. Material and Methods: A screening for syphilis of 500 married pregnant women presenting to antenatal clinics was carried out using the qualitative Rapid Plasma Regent (RPR) test/ Venereal Disease Research Laboratory (VDRL) test. The Treponema Palladium Haem-Agglutination Assay (TPHA) test was used as confirmatory test for all Venereal Disease Research Laboratory (VDRL) test positive cases. Results: A total of 8 women (1.6%) were positive for Venereal Disease Research Laboratory (VDRL) test. Out of these 4 (0.8%) were positive for Treponema Palladium Haem-Agglutination Assay (TPHA) test. All of these cases have bad obstetrical history. Conclusion: The sero-positivity of Venereal Disease Research Laboratory (VDRL) test is (1.6%), considered high among pregnant women reporting in obstetrics clinics of Combined Military Hospital Abbottabad. Similarly sero-positivity of Treponema Palladium Haem-Agglutination Assay (TPHA) test is (0.8%) considered high among the Venereal Disease Research Laboratory (VDRL) test population. Therefore Screening of syphilis in pregnancy especially in patients having bad obstetrical history (BOH) should be incorporated into the study. (author)

  19. The trade-off between accuracy and accessibility of syphilis screening assays.

    Directory of Open Access Journals (Sweden)

    Pieter W Smit

    Full Text Available The availability of rapid and sensitive methods to diagnose syphilis facilitates screening of pregnant women, which is one of the most cost-effective health interventions available. We have evaluated two screening methods in Tanzania: an enzyme immunoassay (EIA, and a point-of-care test (POCT. We evaluated the performance of each test against the Treponema pallidum particle agglutination assay (TPPA as the reference method, and the accessibility of testing in a rural district of Tanzania. The POCT was performed in the clinic on whole blood, while the other assays were performed on plasma in the laboratory. Samples were also tested by the rapid plasma Reagin (RPR test. With TPPA as reference assay, the sensitivity and specificity of EIA were 95.3% and 97.8%, and of the POCT were 59.6% and 99.4% respectively. The sensitivity of the POCT and EIA for active syphilis cases (TPPA positive and RPR titer ≥ 1/8 were 82% and 100% respectively. Only 15% of antenatal clinic attenders in this district visited a health facility with a laboratory capable of performing the EIA. Although it is less sensitive than EIA, its greater accessibility, and the fact that treatment can be given on the same day, means that the use of POCT would result in a higher proportion of women with syphilis receiving treatment than with the EIA in this district of Tanzania.

    Full Text Available Context: Syphilis is a transfusion transmissible infections and it is mandatory to do serological test for syphilis (STS on all donor blood samples. STS is usually based on detection of antibodies against the cardiolipin-lecithin antigen or against the Treponema-specific antigen. STS with good sensitivity and specificity helps enhance blood safety and consolidation of STS along with other transfusion transmittable infections such as human immunodeficiency virus, hepatitis-C virus, and hepatitis-B virus helps in reducing the errors and enhances efficiency. Aims: This study was designed to evaluate the performance of newly introduced VITROS ® syphilis Treponema pallidum agglutination (TPA assay based on enhanced chemiluminescence principle for its analytical performance for use as a STS on donor blood samples at a tertiary care health center in National Capital Region, India. Materials and Methods: A total of 108 random blood units collected from the donors (both voluntary and replacement donors and 28 known syphilis sero-reactive samples stored at −20°C, were used to evaluate the performance of VITROS ® syphilis TPA assay based on enhanced chemiluminescence assay on VITROS ® ECiQ immunodiagnostics system along with its analytical performance in terms of its sensitivity, precision, cross-reactivity and interference studies. Results: VITROS ® syphilis TPA showed 100% sensitivity and specificity with precision (20 days study of <10% co-efficient of variation. There was no cross-reactivity with other viral and auto-immune antibodies. No interference was observed from endogenous interfering substances like free hemoglobin or fats. Conclusions: Performance of the VITROS ® syphilis TPA assay meets the requirements for its use as STS in blood bank, thus allowing consolidation with other transfusion transmittable infections screening assay on chemiluminescence platform, which is highly valuable for optimizing workflow and efficiency.

    This study addresses the lack of empirical studies about the epidemic of syphilis among middle-aged female sex workers (FSWs). The objectives of this study were to investigate prevalence of syphilis, and its potential risk factors among middle-aged FSWs in China. A cross-sectional study with respondent-driven sampling (RDS). A multisite study conducted at three Chinese cites (Nanning, Hefei, and Qingdao) with different levels of sexually transmitted diseases in 2014. 1245 middle-aged female sex workers who were over 35 years old (about 400 per study site). Unprotected commercial sex, and syphilis and HIV infection were biologically tested and measured. The RDS-adjusted prevalence of active syphilis was 17.3% in Hefei, 9.9% in Qingdao, and 5.4% in Nanning. The RDS-adjusted prevalence of prevalent syphilis was between 6.8% and 33.6% in the three cities. The proportion of unprotected sex in the past 48 h verified by the prostate-specific antigen test (PSA) was between 27.8% and 42.4%. Multiple log-binomial regression analyses indicate that middle-aged FSWs who had 5 or more clients in the past week prior to interviews and engaged in unprotected sex were more likely to be active syphilitic cases. Middle-aged FSWs who had rural residency were less likely to be active syphilitic cases. In contrast with previous studies that reported low prevalence of syphilis and high prevalence of protected sex among FSWs in China, both the prevalence of syphilis and unprotected sex were high among middle-aged FSWs. Evidence-based intervention programmes should be developed and evaluated among this vulnerable population in China and other countries with similar settings.

    Full Text Available OBJECTIVE: The objective of this study was to identify possible barriers to control vertical transmission of syphilis and HIV through the analysis of the orientation process of pregnant women from prenatal care to the obstetric center at an university hospital in Sao Paulo (Reference and their return (with their exposed babies for follow-up after hospital discharge (counter-reference. METHODS: It is a retrospective cross-sectional study including interviews with healthcare personnel. Pregnant women with syphilis and/or HIV-infection admitted for labor or miscarriage were identified from August 2006 to August 2007. Routine care for mothers and babies were analyzed. RESULTS: 56 pregnant women were identified: 43 were HIV-infected, 11 had syphilis and two were coinfected (syphilis/HIV; 22 health care professionals were interviewed. Prenatal care was identified in 91.1% of these women: 7/11 (63.6% with syphilis; 44/45 (97.8% HIV-infected or coinfected. The reference for delivery was satisfactory for 57.7% of the syphilis-infected women and 97.7% of the HIV-infected ones. The counter-reference was satisfactory for all babies and mothers at hospital discharge, besides the non-adherence to this recommendation. Interviews with health care professionals showed there are better routines for assisting and following-up pregnant women, puerperal women and HIV-infected or exposed babies than for those infected with syphilis. The epidemiological report and surveillance system are also better for HIV-infected patients. CONCLUSION: The difficulties in the reference and counter-reference system of these women and their babies are evident barriers to control the vertical transmission of these infectious diseases.

    Background Syphilis, a sexually transmitted disease caused by spirochetal bacterium Treponema pallidum, can progress to affect the central nervous system, causing neurosyphilis. Accumulating evidence suggest that regulatory T cells (Tregs) may play an important role in the pathogenesis of syphilis. However, little is known about Treg response in neurosyphilis. Methodology/Principal Findings We analyzed Treg frequencies and Transforming Growth Factor-β (TGF-β) levels in the blood and CSF of 431 syphilis patients without neurological involvement, 100 neurosyphilis patients and 100 healthy donors. Suppressive function of Tregs in peripheral blood was also assessed. Among syphilis patients without neurological involvement, we found that secondary and serofast patients had increased Treg percentages, suppressive function and TGF-β levels in peripheral blood compared to healthy donors. Serum Rapid Plasma Reagin (RPR) titers were positively correlated with Treg numbers in these patients. Compared to these syphilis patients without neurological involvement, neurosyphilis patients had higher Treg frequency in peripheral blood. In the central nervous system, neurosyphilis patients had higher numbers of leukocytes in CSF compared to syphilis patients without neurological involvement. CD4+ T cells were the predominant cell type in the inflammatory infiltrates in CSF of neurosyphilis patients. Interestingly, among these neurosyphilis patients, a significant decrease in CSF CD4+ CD25high Treg percentage and number was observed in symptomatic neurosyphilis patients compared to those of asymptomatic neurosyphilis patients, which may be associated with low CSF TGF-β levels. Conclusions Our findings suggest that Tregs might play an important role in both bacterial persistence and neurologic compromise in the pathogenesis of syphilis. PMID:24244772

    Syphilis infection persists globally contributing to preventable and treatable morbidity and mortality. How extensive early syphilis disseminates is unknown. To better understand the relationship between early syphilis infection and inflammation over time, our study enrolled six individuals recently infected with syphilis for sequential positron emission tomography (PET) scans. We evaluated a case series of six individuals with high syphilis titres (two secondary, two early latent and two latent, unknown duration, but with high titre) who received sequential PET scans to assess inflammation over time and its response to treatment. At time of PET scan, four of the six individuals were co-infected with HIV. One of the four was not on antiretroviral therapy and three of the four were not virally suppressed (viral load of >400 copies/mL). Baseline rapid plasma reagin (RPR) titres ranged from 1:64 to 1:256 (four of the six participants had prior non-reactive RPR results). Five of the six participants had mild to intense hypermetabolic PET scan activity consistent with cervical (n=5), axillary (n=4), inguinal (n=5) and retroperitoneal (n=1) adenopathy. Mild hypermetabolic activity in the thoracic aortic wall, suggesting aortitis, was present among the same five participants and resolved within 30 days for four of the five participants and 60 days for the other participant. However, widespread lymphadenopathy remained present in PET scans up to 3 months following treatment in two participants. We did not find any abnormal PET scan activity of the central nervous system. We found abnormal aortic wall PET scan activity suggesting aortitis to be common in a case series of patients with early syphilis. In research settings, PET scans may be a sensitive tool to monitor inflammation associated with syphilis. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    HIV and congenital syphilis are major public health burdens contributing to substantial perinatal morbidity and mortality globally. Although studies have reported on the costs and cost-effectiveness of rapid diagnostic tests (RDTs) for syphilis screening within antenatal care in a number of resource-constrained settings, empirical evidence on country-specific cost and estimates of single RDTs compared with dual RDTs for HIV and syphilis are limited. A cluster randomised controlled study design was used to compare the incremental costs of two testing algorithms: (1) single RDTs for HIV and syphilis and (2) dual RDTs for HIV and syphilis, in 12 health facilities in Bogota and Cali, Colombia. The costs of single HIV and syphilis RDTs and dual HIV and syphilis RDTs were collected from each of the health facilities. The economic costs per woman tested for HIV and syphilis and costs per woman treated for syphilis defined as the total costs required to test and treat one woman for syphilis were estimated. A total of 2214 women were tested in the study facilities. Cost per pregnant woman tested and cost per woman treated for syphilis were US$10.26 and US$607.99, respectively in the single RDT arm. For the dual RDTs, the cost per pregnant woman tested for HIV and syphilis and cost per woman treated for syphilis were US$15.89 and US$1859.26, respectively. Overall costs per woman tested for HIV and syphilis and cost per woman treated for syphilis were lower in Cali compared with Bogota across both intervention arms. Staff costs accounted for the largest proportion of costs while treatment costs comprised <1% of the preventive programme. Findings show lower average costs for single RDTs compared with dual RDTs with costs sensitive to personnel costs and the scale of output at the health facilities. NCT02454816; results.

    Untreated syphilis in pregnancy is associated with adverse clinical outcomes to the infant. The study aimed to estimate the public health burden resulting from adverse pregnancy outcomes due to syphilis infection among pregnant women not screened for syphilis in 43 countries in sub-Saharan Africa. Estimated country-specific incidence of syphilis was generated from annual number of live births, the proportion of women with at least 1 antenatal care (ANC) visit, the syphilis prevalence rate, and the proportion of women screened for syphilis during ANC.Adverse pregnancy outcome data (stillbirth, neonatal death, low birth weight, and congenital syphilis) were obtained from published sources. Disability-adjusted life-year (DALY) estimates were calculated using undiscounted local life expectancy, the neonatal standard loss function, and relevant disability weights. The model assessed the potential impact of raising ANC coverage to at least 95% and syphilis screening to at least 95% (World Health Organization targets). For all 43 sub-Saharan Africa countries, the estimated incidence of adverse pregnancy outcomes was 205,901 (95% confidence interval [CI], 113,256-383,051) per year, including stillbirth (88,376 [95% CI, 60,854-121,713]), neonatal death (34,959 [95% CI, 23,330-50,076]), low birth weight (22,483 [95% CI, 0-98,847]), and congenital syphilis (60,084 [95% CI, 29,073-112,414]), resulting in approximately 12.5 million DALYs. Countries with the greatest burden are (in DALYs, millions) Democratic Republic of the Congo (1.809), Nigeria (1.598), Ethiopia (1.466), and Tanzania (0.961). Attaining World Health Organization targets could reduce the burden by 8.5 million DALYs. Substantial infant mortality and morbidity results from maternal syphilis infection concentrated in countries with low access to ANC or low rates of syphilis screening.

    Substantial increases in syphilis during 2008–2013 were reported in the US Pacific Northwest state of Oregon, especially among men who have sex with men (MSM). The authors aimed to characterize the ongoing epidemic and identify possible gaps in clinical management of early syphilis (primary, secondary, and latent syphilis ≤1 year) among MSM in Multnomah County, Oregon to inform public health efforts. Administrative databases were used to examine trends in case characteristics during 2008–2013. Medical records were abstracted for cases occurring in 2013 to assess diagnosis, treatment, and screening practices. Early syphilis among MSM increased from 21 cases in 2008 to 229 in 2013. The majority of cases occurred in HIV-infected patients (range: 55.6%–69.2%) diagnosed with secondary syphilis (range: 36.2%–52.4%). In 2013, 119 (51.9%) cases were diagnosed in public sector medical settings and 110 (48.0%) in private sector settings. Over 80% of HIV-infected patients with syphilis were in HIV care. Although treatment was adequate and timely among all providers, management differed by provider type. Among HIV-infected patients, a larger proportion diagnosed by public HIV providers than private providers were tested for syphilis at least once in the previous 12 months (89.6% vs. 40.0%; p syphilis in Multnomah County remained largely unchanged during 2008–2013. Syphilis control measures were well established, but early syphilis among MSM continued to increase. The results suggest a need to improve syphilis screening among private clinics, but few gaps in clinical management were identified. PMID:27308806

    Syphilis is a multistage sexually transmitted disease that remains a serious public health concern worldwide. The coexistence of Treponema pallidum with other closely related members of spirochaeta, such as Leptospira spp. and Borrelia burgdorferi, has complicated the serodiagnosis due to cross-reactive antigens. In this study, recombinant Tp0821 protein was expressed in Escherichia coli and purified by metal affinity chromatography. Then enzyme-linked immunosorbent assays (ELISAs) based on Tp0821 for the detection of specific antibodies were established. The relative positive rates of the IgM ELISA and the IgG ELISA were found to be 91·0 and 98·3%, respectively, when screening 578 syphilis specimens. The specificities were 94·3 and 100%, respectively, when cross-checking with serum samples obtained from 30 patients with Lyme disease, five patients with leptospirosis, and 52 uninfected controls. In addition, relative positive rates and specificities of Tp0821 for human sera were all 100% in Western blotting. When compared to the syphilis diagnostic tests commonly used in clinical settings, we found that the results of Tp0821-based ELISAs correlated well with the results of the treponemal tests, specifically the T. pallidum particle agglutination (TP-PA) test and the chemiluminescent immunoassay (CIA). Thus, these findings identify Tp0821 as a novel serodiagnostic candidate for syphilis. In this study, we expressed and purified the Treponema pallidum protein Tp0821 and developed Tp0821-based enzyme-linked immunosorbent assays (ELISAs) for the detection of specific antibodies. The serodiagnostic performance of the recombinant protein was then evaluated. When compared to the results of syphilis diagnostic tests commonly used in clinical settings, we found that the reactivities of syphilitic sera with the recombinant antigen correlated well with the results of the treponemal tests, specifically the T. pallidum particle agglutination (TP-PA) test and the

    Full Text Available OBJECTIVE: The goal of this study was to understand the knowledge about AIDS, identify the correlates and determine the prevalence of HIV infection, syphilis, HCV among migrant workers in Zhejiang, China. METHODS: A cross-sectional study using face-to-face anonymous questionnaire interviews was conducted and blood samples were collected for HIV, syphilis and Hepatitis C infection screening. RESULTS: 17,377 (92.8% of 18,730 migrant workers approached were interviewed. Among 17,377 participants, the HIV/AIDS knowledge rate was 66.2%. A total of 12,694 (73% of the participants reported having ever had sexual intercourse, with 30.1% of single participants reporting having had sexual intercourse. Among those respondents with sexual experiences, 7.5% admitted they had two or more sexual partners and 4.9% reported having had sex with casual (unpaid partners in the previous 12 months, whilst 3.7% had paid for sex. More than half of those who had paid for sex (59.4% had not used a condom every time in their sexual acts with the sex workers. Multiple logistic regression analysis indicated that high risk sexual behavior (defined as sex with a casual or commercial sex partner without using a condom consistently was associated with being divorced or widowed (P<0.05 for single; male gender; shorter duration of stay in Zhejiang; working in factory, market or domestic service (P<0.05 for odd job; having a province of origin inside Zhejiang; and drug use. The prevalence of HIV and HCV infections were 0.02% (95% CI: 0.01%-0.06% and 0.40% (95%CI: 0.31%-0.51%, respectively. The prevalence of syphilis among those who were sexually active was 0.55% (95% CI: 0.43%-0.70%. Risk factors for syphilis included shorter duration of stay in Zhejiang, ethnic minority status, being divorced or widowed and having had multiple sex partners. CONCLUSIONS: Much greater efforts are needed to promote safer sex, and programs for the control of syphilis need to be tailored for migrant

    To determine the performance of the FTA-ABS (IgM) test in congenital syphilis after eliminating interference by IgM rheumatoid factor (RF) and preventing competitive inhibition by IgG. The FTA-ABS (IgM) test was carried out before and after RF removal (achieved by immunoprecipitation of the IgG) in infants with congenital syphilis and controls. Newborns delivered in the Peninsula Maternal and Neonatal Services in Cape Town and infants presenting at Red Cross War Memorial Children's Hospital. Infants with congenital syphilis aged 0-4 months were divided into those with clinical signs at presentation and those who were asymptomatic at delivery. In addition, patients without congenital syphilis but with similar clinical signs at presentation were investigated as were control infants. The diagnosis of congenital syphilis was based on the criteria suggested by Kaufman et al (1977). Amongst symptomatic infants with congenital syphilis the FTA-ABS (IgM) test was positive in 34 (92%) of 37 cases prior to abolishing the RF effect and in 29 (78.4%) of 37 cases afterwards (p = 0.19). In 12 cases of congenital syphilis who were asymptomatic at birth, 10 had positive FTA-ABS (IgM) tests before RF removal and only three had positive tests afterwards (p = 0.006). False positive tests were not found amongst 15 symptomatic infants whose clinical features mimicked those of the infants with congenital syphilis. Among 51 healthy infants the test had a false-positive rate of 2% in newborns and 13% in older infants. The false positive reactions were eradicated by IgG precipitation. Following IgG and RF removal there was an improvement in the specificity of the FTA-ABS (IgM) test but this was at the expense of a loss of sensitivity, particularly in asymptomatic newborns. For newborns, if the FTA-ABS (IgM) test was positive, the patient was likely to require treatment for congenital syphilis, regardless of whether the result was due to the presence of RF or specific IgM.

    HIV and sexually transmitted disease (STD) surveillance patterns in Arizona suggested the need for integrated data analyses to identify trends. We compiled all HIV/AIDS cases diagnosed from 1998 to 2008 that were reported in Arizona and syphilis or gonorrhea cases diagnosed from 1998 to 2008 in Arizona. We used deterministic matching to identify individuals who were diagnosed with HIV and one or more STDs, and calculated time intervals between diagnoses. Of 23,940 people with HIV/AIDS reported from 1998 to 2008, 1,899 (2.6%) had at least one syphilis or gonorrhea diagnosis from 1998 to 2008. Approximately 85% of these cases reported male-to-male sexual contact. Among males with syphilis, HIV coinfection increased from 0.5% in 1998 to 29.1% in 2008. Among males with gonorrhea, HIV coinfection increased from 2.0% in 1998 to 3.1% in 2008. Among HIV cases diagnosed from 2004 to 2008 and reported with at least one syphilis or gonorrhea diagnosis, the majority of syphilis cases (76.1%) were diagnosed at or after HIV diagnosis, whereas a majority of gonorrhea cases (54.9%) were diagnosed prior to HIV diagnosis. Use of the deterministic matching method identified increases in STD infections among HIV-infected people. The routine performance of this cross-matching method may be a useful tool in identifying these high-risk individuals so that targeted partner services and appropriate care referrals may be used in a timely fashion.

    Full Text Available BACKGROUND: Routine surveillance using convenient sampling found low prevalence of HIV and syphilis among female sex workers in China. Two consecutive surveys using respondent driven sampling were conducted in 2008 and 2009 to examine the prevalence of HIV and syphilis among female sex workers in Jinan, China. METHODS: A face-to-face interview was conducted to collect demographic, behavioral and service utilization information using a structured questionnaire. Blood samples were drawn for serological tests of HIV-1 antibody and syphilis antibody. Respondent Driven Sampling Analysis Tool was used to generate population level estimates. RESULTS: In 2008 and in 2009, 363 and 432 subjects were recruited and surveyed respectively. Prevalence of syphilis was 2.8% in 2008 and 2.2% in 2009, while no HIV case was found in both years. Results are comparable to those from routine sentinel surveillance system in the city. Only 60.8% subjects in 2008 and 48.3% in 2009 reported a consistent condom use with clients during the past month. Over 50% subjects had not been covered by any HIV-related services in the past year, with only 15.6% subjects in 2008 and 13.1% in 2009 ever tested for HIV. CONCLUSIONS: Despite the low prevalence of syphilis and HIV, risk behaviors are common. Targeted interventions to promote the safe sex and utilization of existing intervention services are still needed to keep the epidemic from growing.

    The 2008 UK syphilis guideline recommends infants born to women with any positive syphilis serology be followed up until both treponemal and nontreponemal tests are negative to exclude congenital syphilis, whereas Centers for Disease Control and Prevention guidelines recommend using only nontreponemal tests. Historically, we had low infant follow-up rates with no coherent pathways. We initiated a change in multidisciplinary team practice of infant testing for syphilis in 2011 and evaluated the results before and after by retrospective review of testing of infants born to women with positive syphilis serology between 2005 and 2012. A total of 28 infants' mothers were treated in pregnancy (termed 'high risk'); 26 had adequate treatment prior to pregnancy (termed 'low risk'). There was a significant increase in serological testing after 2011 compared with before (83% versus 48%; OR 5.07 [95% CI 1.22-22.77] p = 0.01) but mainly in low risk infants with no significant improvement in high risk infants who are the priority group. Using nontreponemal tests only in the infants would have reduced the tests required by at least 50%, allowing health resources to be concentrated on achieving adequate follow-up for those infants most at risk. © The Author(s) 2015.

    The impact of untreated syphilis during pregnancy on neonatal health remains a major public health threat worldwide. Given the high prevalence of syphilis during pregnancy in Zambia and Democratic Republic of Congo (DRC), the Preventive Congenital Syphilis Trial (PCS Trial), a cluster randomized trial, was proposed to increase same-day screening and treatment of syphilis during antenatal care visits. To design an accepted and feasible intervention, we conducted a qualitative  formative research. Our objective was to identify context-specific  barriers and facilitators to the implementation of antenatal screening and treatment during pregnancy. Qualitative research included in-depth semi-structured interviews with clinic administrators, group interviews with health care providers, and focus groups with pregnant women in primary care clinics (PCCs) in Kinshasa (DRC) and Lusaka (Zambia). A total of 112 individuals participated in the interviews and focus groups. Barriers for the implementation of syphilis testing and treatment were identified at the a) system level: fragmentation of the health system, existence of ANC guidelines in conflict with proposed intervention, poor accessibility of clinics (geographical and functional), staff and product shortages at the PCCs; b) healthcare providers' level: lack of knowledge and training about evolving best practices, reservations regarding same-day screening and treatment; c) Pregnant women level: late enrollment in ANC, lack of knowledge about consequences and treatment of syphilis, and stigma. Based on these results, we developed recommendations for the design of the PCS Trial intervention. This research allowed us to identify barriers and facilitators to improve the feasibility and acceptability of a behavioral intervention. Formative research is a critical step in designing appropriate and effective interventions by closing the "know-do gap".

    We carried out an independent short-term impact evaluation of a social marketing campaign designed to reduce syphilis infections among men who have sex with men in south Florida in 2004. Venue-based surveys were conducted shortly after the campaign began and 6 months later to assess changes in exposure to campaign materials, awareness, knowledge about syphilis, perceptions of risk, sexual behavior, clinic visits, and testing and treatment for syphilis among participants. Exposure to social marketing campaign materials increased from 18.0% at baseline to 36.5% at follow-up (Pcampaign objectives were fully met. The interventions were insufficient to produce a significant impact among men who have sex with men in south Florida.

    The authors have taken the Italian city of Ferrara as an example of the remedies against syphilis, commonly used worldwide in the 1800s. After having identified the terminologies used to diagnose syphilis, they evidence the legislative behaviours of the government authorities in 19th century in Italy and, in particular, the social and sanitary measures taken in Ferrara to limit the spread of the syphilis epidemic. Historical sources permitted description of the remedies employed in Ferrara from the beginning to the end of that century, not only to treat conditions linked directly to the malady itself, but also its complications and secondary pathologies. The pharmacopoeia written for the apothecaries of Ferrara by Antonio Campana, a famous Professor of Pharmaceutical Chemistry and Botany, won a great reputation and distribution in the international medical world not only of the first half of the 1800s. His authoritative work was much appreciated in Italy and abroad.

  1. Postirradiation cardiovascular dysfunction

    Cardiovascular dysfunction may be defined as the inability of any element of the cardiovascular system to perform adequately upon demand, leading to inadequate performance and nutritive insufficiency of various parts of the body. Exposure to supralethal doses of radiation (accidental and therapeutic) has been show to induce significant alterations in cardiovascular function in man. These findings indicate that, after irradiation, cardiovascular function is a major determinant of continued performance and even survival. For the two persons who received massive radiation doses (45 and 88 Gy, respectively) in criticality accidents, the inability to maintain systematic arterial blood pressure (AP) was the immediate cause of death. In a study of cancer patients given partial-body irradiation, two acute lethalities were attributed to myocardial infarction after an acute hypotensive episode during the first few hours postexposure. Although radiation-induced cardiovascular dysfunction has been observed in many species, its severity, duration, and even etiology may vary with the species, level of exposure, and dose rate. For this reason, our consideration of the effects of radiation on cardiovascular performance is limited to the circulatory derangements that occur in rat, dog, and monkey after supralethal doses and lead to radiation-induced cardiovascular dysfunction in these experimental models. The authors consider other recent data as they pertain to the etiology of cardiovascular dysfunction in irradiated animals

    To analyze the results of syphilis specific serological tests among entry personnel in Beijing port during year 2012-2014 in order to provide evidence for the prevention and control of syphilis. Demographics data and syphilis specific test results of entry personnel were obtained from the information system of Beijing International Travel Healthcare Center and input into Excel 2016. Database for entry personnel was built up accordingly and was analyzed by IBM SPSS22.0. The number of entry personnel in Beijing port during year 2012-2014 was 106 302 person-time. According to the evaluation criteria, 71 308 persons were recruited and analyzed, of whom 277 were tested serologically positive and the total prevalence was 0.39% (95% CI: 0.34%-0.43%). The prevalence was highest in the persons aged 40-49 years (0.81%) and was higher in males (0.50%) than in females (0.23%). The persons from Africa held higher prevalence (1.27%) than from other five regions. As multivariate logical regression analysis indicated that the risk of syphilis infection was 10.38 times more in the persons aged 40-49 years than in the persons 0.05). Twenty-seven seropositive cases were found within 6 246 entry persons who were tested repeatedly during the research period, 9 of which were seroconversion cases so that the cumulative conversion rate was 0.14% (9/6 228). The average conversion time was (6.3±3.0) months. There was no statistical significance between the cumulative seroconversion rates of the persons with different genders and nationalities (P of Fisher's exact test>0.05). Serological detection of syphilis for entry personnel in Beijing port and syphilis-related health education should be reinforced to reduce the risk of disease importing and spreading, protect susceptible subjects and promote health.

    To assess the effectiveness of a dual rapid test compared to a single rapid test for syphilis and HIV screening. A cluster-randomized open-label clinical trial was performed in 12 public antenatal care (ANC) centers in the cities of Bogotá and Cali, Colombia. Pregnant women who were over 14 years of age at their first antenatal visit and who had not been previously tested for HIV and syphilis during the current pregnancy were included. Pregnant women were randomized to single HIV and single syphilis rapid diagnostic tests (Arm A) or to dual HIV and syphilis rapid diagnostic tests (Arm B). The four main outcomes measured were: (1) acceptability of the test, (2) uptake in testing, (3) treatment on the same day (that is, timely treatment), and (4) treatment at any time for positive rapid test cases. Bivariate and multivariate analyses were calculated to adjust for the clustering effect and the period. A total of 1 048 patients were analyzed in Arm A, and 1 166 in Arm B. Acceptability of the rapid tests was 99.8% in Arm A and 99.6% in Arm B. The prevalence of positive rapid tests was 2.21% for syphilis and 0.36% for HIV. Timely treatment was provided to 20 of 29 patients (69%) in Arm A and 16 of 20 patients (80%) in Arm B (relative risk (RR), 1.10; 95% confidence interval (CI): (1.00 -1.20). Treatment at any time was given to 24 of 29 patients (83%) in Arm A and to 20 of 20 (100%) in Arm B (RR, 1.11; 95% CI: 1.01-1.22). There were no differences in patient acceptability, testing and timely treatment between dual rapid tests and single rapid tests for HIV and syphilis screening in the ANC centers. Same-day treatment depends also on the interpretation of and confidence in the results by the health providers.

    Currently, the efficacy of syphilis treatment is measured with anti-lipid antibody tests. These can take months to indicate cure and, as a result, syphilis treatment trials require long periods of follow-up. The causative organism, Treponema pallidum (T. pallidum), is detectable in the infectious lesions of early syphilis using DNA amplification. Bacteraemia can likewise be identified, typically in more active disease. We hypothesise that bacterial clearance from blood and ulcers will predict early the standard serology-measured treatment response and have developed a qPCR assay that could monitor this clearance directly in patients with infectious syphilis. Patients with early syphilis were given an intramuscular dose of benzathine penicillin. To investigate the appropriate sampling timeframe samples of blood and ulcer exudate were collected intensively for T. pallidum DNA (tpp047 gene) and RNA (16S rRNA) quantification. Sampling ended when two consecutive PCRs were negative. Four males were recruited. The mean peak level of T. pallidum DNA was 1626 copies/ml whole blood and the mean clearance half-life was 5.7 hours (std. dev. 0.53). The mean peak of 16S rRNA was 8879 copies/ml whole blood with a clearance half-life of 3.9 hours (std. dev. 0.84). From an ulcer, pre-treatment, 67,400 T. pallidum DNA copies and 7.08 x 107 16S rRNA copies were detected per absorbance strip and the clearance half-lives were 3.2 and 4.1 hours, respectively. Overall, T. pallidum nucleic acids were not detected in any sample collected more than 56 hours (range 20-56) after treatment. All patients achieved serologic cure. In patients with active early syphilis, measuring T. pallidum levels in blood and ulcer exudate may be a useful measure of treatment success in therapeutic trials. These laboratory findings need confirmation on a larger scale and in patients receiving different therapies.

    Full Text Available Syphilis co-infection risk has increased substantially among HIV-infected men who have sex with men (MSM. Frequent screening for syphilis and treatment of men who test positive might be a practical means of controlling the risk of infection and disease sequelae in this population.We evaluated the cost-effectiveness of strategies that increased the frequency and population coverage of syphilis screening in HIV-infected MSM receiving HIV care, relative to current standard of care.We developed a state-transition microsimulation model of syphilis natural history and medical care in HIV-infected MSM receiving care for HIV. We performed Monte Carlo simulations using input data derived from a large observational cohort in Ontario, Canada, and from published biomedical literature. Simulations compared usual care (57% of the population screened annually to different combinations of more frequent (3- or 6-monthly screening and higher coverage (100% screened. We estimated expected disease-specific outcomes, quality-adjusted survival, costs, and cost-effectiveness associated with each strategy from the perspective of a public health care payer.Usual care was more costly and less effective than strategies with more frequent or higher coverage screening. Higher coverage strategies (with screening frequency of 3 or 6 months were expected to be cost-effective based on usually cited willingness-to-pay thresholds. These findings were robust in the face of probabilistic sensitivity analyses, alternate cost-effectiveness thresholds, and alternate assumptions about duration of risk, program characteristics, and management of underlying HIV.We project that higher coverage and more frequent syphilis screening of HIV-infected MSM would be a highly cost-effective health intervention, with many potentially viable screening strategies projected to both save costs and improve health when compared to usual care. The baseline requirement for regular blood testing in this

    Full Text Available The aim of this study was to analyze the characteristics and clinical manifestations of secondary syphilis among patients registered at the City Institute for Skin and Venereal Diseases in Belgrade, during the period from 2010 to 2014. The study was designed as a case-note review. In the five-year period, a total of 62 patients with secondary syphilis were registered. The average patient age was 32 years. There were 45 (72.6% HIV-negative, and 17 (27.4% HIV-positive patients. The incidence of HIV–positive patients was significantly different from random distribution (p = 0.016. All HIV-positive patients were unmarried men. A significant percentage of HIV-positive patients were unemployed (p < 0.001, reported unknown source of infection (p = 0.002 and were all homosexuall (p = 0.026. More than 25% of all patients with syphilis had a history of chancres, and it was still present at the time of examination in 11.3% of all patients. The majority of cases (87.1% had a rash, and lymphadenopathy was found in 20% of patients. However, syphilitic alopecia was detected only in HIV-positive cases (p = 0.004. There were no statistically significant differences between HIV-positive and HIV-negative patients in regard to other clinical manifestations, such as mucous patches and condylomata lata. Being a great imitator, secondary syphilis may manifest in a myriad of diverse morphological entities and clinical manifestations. We review a range of cutaneous manifestations of secondary syphilis and skin diseases it may mimic. Clinicians must be vigilant and consider syphilis in differential diagnosis, and maintain a high index of suspicion, especially when assessing vulnerable populations, such as men who have sex with men and HIV-infected individuals.

    Patients coinfected with syphilis and human immunodeficiency virus (HIV) may have a slower decrease in rapid plasma reagin (RPR) titers. Currently a single dose of 2.4 million units of intramuscular benzathine penicillin G (BPG) is recommended for the treatment of early syphilis. Some observational studies have suggested that this regimen may lead to high failure rates in coinfected patients. We conducted an open-label randomized clinical trial to compare the efficacy of single-dose and 3-dose regimens of BPG for the treatment of early syphilis in HIV-infected individuals. RPR titers were monitored every 3 months. Treatment success was defined as a decrease in RPR titers of ≥2 dilutions (4-fold) during a 12-month follow-up period. Sixty-four patients were included. In the intention-to-treat analysis, treatment success rates were 80% (28 of 35 subjects) and 93% (27 of 29 subjects) in the single-dose and 3-dose regimens, respectively (absolute difference, 13% [95% confidence interval {CI}, -5% to 30%; P = .17). In the per-protocol analysis, success rates were 93% (27 of 29) and 100% in the single-dose and 3-dose regimens, respectively (absolute difference, 7% [95% CI, -7% to 22%]; P = .49). CD4 T-cell count, RPR titer and syphilis stage did not affect treatment results. When compared with a single dose of BPG, a 3-dose regimen did not improve syphilis serological outcomes. Our results support the Centers for Disease Control and Prevention recommendation of a single dose of BPG in HIV-infected patients with early syphilis. NCT02611765. © The Author 2017.

    Background Syphilis co-infection risk has increased substantially among HIV-infected men who have sex with men (MSM). Frequent screening for syphilis and treatment of men who test positive might be a practical means of controlling the risk of infection and disease sequelae in this population. Purpose We evaluated the cost-effectiveness of strategies that increased the frequency and population coverage of syphilis screening in HIV-infected MSM receiving HIV care, relative to current standard of care. Methods We developed a state-transition microsimulation model of syphilis natural history and medical care in HIV-infected MSM receiving care for HIV. We performed Monte Carlo simulations using input data derived from a large observational cohort in Ontario, Canada, and from published biomedical literature. Simulations compared usual care (57% of the population screened annually) to different combinations of more frequent (3- or 6-monthly) screening and higher coverage (100% screened). We estimated expected disease-specific outcomes, quality-adjusted survival, costs, and cost-effectiveness associated with each strategy from the perspective of a public health care payer. Results Usual care was more costly and less effective than strategies with more frequent or higher coverage screening. Higher coverage strategies (with screening frequency of 3 or 6 months) were expected to be cost-effective based on usually cited willingness-to-pay thresholds. These findings were robust in the face of probabilistic sensitivity analyses, alternate cost-effectiveness thresholds, and alternate assumptions about duration of risk, program characteristics, and management of underlying HIV. Conclusions We project that higher coverage and more frequent syphilis screening of HIV-infected MSM would be a highly cost-effective health intervention, with many potentially viable screening strategies projected to both save costs and improve health when compared to usual care.

    cholesterol might not cause cardiovascular disease as originally thought has now generated renewed interest in raised concentrations of triglycerides. This renewed interest has also been driven by epidemiological and genetic evidence supporting raised triglycerides, remnant cholesterol, or triglyceride......-rich lipoproteins as an additional cause of cardiovascular disease and all-cause mortality. Triglycerides can be measured in the non-fasting or fasting states, with concentrations of 2-10 mmol/L conferring increased risk of cardiovascular disease, and concentrations greater than 10 mmol/L conferring increased risk...... of acute pancreatitis and possibly cardiovascular disease. Although randomised trials showing cardiovascular benefit of triglyceride reduction are scarce, new triglyceride-lowering drugs are being developed, and large-scale trials have been initiated that will hopefully provide conclusive evidence...

    The province of Manitoba, Canada, with a population of approximately 1.3 million, has been experiencing increased incidence of syphilis cases since 2015. In this study, we examined the detection of Treponema pallidum DNA in 354 clinical samples from 2012 to 2016, and determined molecular types and mutations conferring resistance to azithromycin in the polymerase chain reaction (PCR)-positive samples. T. pallidum DNA detection was done by PCR amplification of tpp47, bmp, and polA genes. Syphilis serology results were reviewed for the PCR-positive cases. Molecular typing of syphilis strains was done by analysis of the T, pallidum arp, tpr, and tp0548 gene targets as well as partial sequencing of the 23S rRNA gene for azithromycin resistance. Of the 354 samples tested, 74 individual cases were PCR positive. A result from the treponemal antibody chemiluminescent microparticle immunoassay test was positive in 72 of these cases and that from the Venereal Disease Research Laboratory testing was positive in 66. Mutations conferring resistance to azithromycin were found in all 74 PCR-positive samples. Molecular typing was completed on 57 PCR-positive samples, and 12 molecular types were identified with 14d/g found in 63.2%. Increased strain diversity was observed with 8 molecular types detected in 2016, whereas only 2 to 3 types were found in 2012 to 2014. A patient with 2 episodes of infection 9 months apart caused by different molecular strain types was also identified. The finding of an increase in genetic diversity in the strains in this study and an increase in macrolide resistance compared with previous Canadian reports highlighted the need for continued surveillance including strain characterization.

    Antenatal care (ANC) is provided to prevent, diagnose early and treat pregnant women for a variety of diseases. The objective of this study was to determine the seroprevalences of syphilis, human immunodeficiency virus (HIV) and hepatitis B virus (HVB) and asymptomatic urinary tract infections and the prevalence of hypertension and anemia among pregnant women attending the antenatal clinic at Gambo Rural Hospital in southern Ethiopia. The following tests were conducted among study subjects: hemoglobin (Hgb) level, rapid plasma reagin (RPR) for syphilis, anti-HIV antibodies, hepatitis B surface antigen (HBsAg) and urine analysis. A total of 574 pregnant women were included in this study. The mean age of the participants was 25.7 (SD: 4.8) years old; 88.2% were living in urban areas and 11.8% in rural areas. Sixty-seven point two percent of participants began their attended care during the second trimester of their pregnancy. Overall, anemia (Hgb urinary tract infection (having ≥10 white blood cells /high power field in the urine) was present in 12.7% of participants (95% CI: 10.0-15.5). The RPR test was positive in two patients (0.3%; 95% CI: 0.1-1.3). The prevalences of positive test for HBsAg and HIV-1 were 2.3% (95% CI: 1.3-3.8) and 0.2% (95% CI: 0.03-0.9), respectively. No HIV-2 cases were detected. Our data show relatively low prevalences of anemia, hypertension, urinary tract infection, syphilis, HIV, and hepatitis B virus infections among study subjects at a rural antenatal clinic in southern Ethiopia.

    Treponema pallidum, the causative agent of venereal syphilis, is a microaerophilic obligate pathogen of humans. As it disseminates hematogenously and invades a wide range of tissues, T. pallidum presumably must tolerate substantial oxidative stress. Analysis of the T. pallidum genome indicates that the syphilis spirochete lacks most of the iron-binding proteins present in many other bacterial pathogens, including the oxidative defense enzymes superoxide dismutase, catalase, and peroxidase, but does possess an orthologue (TP0823) for neelaredoxin, an enzyme of hyperthermophilic and sulfate-reducing anaerobes shown to possess superoxide reductase activity. To analyze the potential role of neelaredoxin in treponemal oxidative defense, we examined the biochemical, spectroscopic, and antioxidant properties of recombinant T. pallidum neelaredoxin. Neelaredoxin was shown to be expressed in T. pallidum by reverse transcriptase-polymerase chain reaction and Western blot analysis. Recombinant neelaredoxin is a 26-kDa alpha(2) homodimer containing, on average, 0.7 iron atoms/subunit. Mössbauer and EPR analysis of the purified protein indicates that the iron atom exists as a mononuclear center in a mixture of high spin ferrous and ferric oxidation states. The fully oxidized form, obtained by the addition of K(3)(Fe(CN)(6)), exhibits an optical spectrum with absorbances at 280, 320, and 656 nm; the last feature is responsible for the protein's blue color, which disappears upon ascorbate reduction. The fully oxidized protein has a A(280)/A(656) ratio of 10.3. Enzymatic studies revealed that T. pallidum neelaredoxin is able to catalyze a redox equilibrium between superoxide and hydrogen peroxide, a result consistent with it being a superoxide reductase. This finding, the first description of a T. pallidum iron-binding protein, indicates that the syphilis spirochete copes with oxidative stress via a primitive mechanism, which, thus far, has not been described in pathogenic

    Full Text Available Abstract Background According to the surveillance system in Turkey, most diseases are notified only by clinicians, without involving laboratory notification. It is assumed that a considerable inadequacy in notifications exists; however, this has not been quantified by any researcher. Our aim was to evaluate the completeness of communicable disease surveillance in the province of Izmir, Turkey for the year of 2003 by means of estimating the incidences of diseases. Methods Data on positive laboratory results for the notifiable and serologically detectable diseases hepatitis A, B, C, brucellosis, syphilis, measles and HIV detected in 2003 in Izmir (population 3.5 million were collected from serology laboratories according to WHO surveillance standards and compared to the notifications received by the Provincial Health Directorate. Data were checked for duplicates and matched. Incidences were estimated with the capture-recapture method. Sensitivities of both notifications and laboratory data were calculated according to these estimates. Results Among laboratories performing serologic tests (n = 158 in Izmir, 84.2% accepted to participate, from which 23,515 positive results were collected. Following the elimination of duplicate results as well as of cases residing outside of Izmir, the total number was 11,402. The total number of notifications was 1802. Notification rates of cases found in laboratories were 31.6% for hepatitis A, 12.1% for acute hepatitis B, 31.8% for brucellosis, 25.9% for syphilis and 100% for HIV confirmation. Conclusions It was discovered that for hepatitis A, B, C, brucellosis and syphilis, there is a considerable under-notification by clinicians and that laboratory data has the potential of contributing greatly to their surveillance. The inclusion of laboratories in the surveillance system of these diseases could help to achieve completeness of reporting.

    In 2012, the WHO estimated that 6 million new cases of syphilis per year would occur worldwide, including 937 000 in Brazil. Early diagnosis and treatment of syphilis are essential to reduce morbidity and prevent transmission. The availability of rapid tests (RTs) for this diagnosis means that testing can be performed more quickly, as a point-of-care test, even in non-laboratory environments and requires only simple technical training to antibodies detection. The objective of this study was to evaluate the performance and operational aspects of seven commercially available RTs for syphilis in Brazil. Seven rapid treponemal tests were evaluated for sensitivity, specificity, accuracy and Kappa value, according to a panel composed of 493 members. The operational performance of the assay was also determined for these tests. The seven RTs showed sensitivity ranging from 94.5% to 100% when compared with the reference tests and specificity of between 91.5% and 100%. All the RTs evaluated presented good operational performance, and only one failed to present the minimum specificity as defined by Brazil's Ministry of Health. All the tests presented good operational performance, and the professionals who performed them considered them to be easy to use and interpret. This evaluation is important for making informed choices of tests to be used in the Brazilian Unified Health System. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Syphilis is a sexually transmitted disease known to present with highly variable manifestations, especially when left untreated. Patients who present to Internal Medicine Departments with fever and a rash are always a diagnostic challenge since mild viral diseases and life-threatening bacterial infections may manifest themselves similarly. In the following case presentation, we describe a patient with 1 month’s duration of fever and rash on the palms of the hand and soles of the feet, in the form of erythema multiforme (EM-like lesions. His disease was diagnosed as secondary syphilis, once again justifying its name: the “great masquerader".

    Abstract Clients of female sex workers (CFSWs) are a bridge population for the spread of HIV and syphilis to low or average risk heterosexuals. Most studies have examined the point prevalence of these infections in CFSWs. Limited evidence suggests that older age CFSWs are at a higher risk of acquiring sexually transmitted diseases compared with younger clients. Thus, we sought to describe long-term trends in HIV, syphilis, and hepatitis C (HCV) to better understand how these infections differ by sex worker classification and client age. We also examined trends in HIV, syphilis, and HCV among categories of female sex workers (FSWs). We conducted serial cross-sectional studies from 2010 to 2015 in Guangxi autonomous region, China. We collected demographic and behavior variables. FSWs and their clients were tested for HIV, syphilis, and HCV antibodies. Positive HIV and syphilis serologies were confirmed by Western blot and rapid plasma regain, respectively. Clients were categorized as middle age (40–49 years) and older clients (≥50 years). FSWs were categorized as high-tier, middle-tier, or low-tier based on the payment amount charged for sex and their work venue. Chi-square test for trends was used for testing changes in prevalence over time. By 2015, low-tier FSWs (LTFSWs) accounted for almost half of all FSWs; and they had the highest HIV prevalence at 1.4%. HIV prevalence declined significantly for FSWs (high-tier FSW, P = 0.003; middle-tier FSWs; P = 0.021; LTFSWs, P HIV prevalence increased for older age clients (1.3%–2.0%, P = 0.159) while syphilis prevalence remained stable. HCV infections were halved among older clients in 3 years (1.7%–0.8%, P sex with men or intravenous drug use. Clients preferred LTFSWs, especially older clients (81.9%). Our results suggest that HIV and syphilis infections are increasing in older clients who prefer LTFSWs. HIV and syphilis are likely increasing in Guangxi Province through heterosexual transmission

    Ocular syphilis is reemerging as an important cause of uveitis in the new era of common co-infection with HIV. This study will reveal the clinical and laboratory characteristics in the group of individuals co-infected with ocular syphilis and HIV compared with HIV-negative individuals. In this retrospective observational case series, medical records of patients diagnosed with ocular syphilis with serologic support from 2008 to 2014 were reviewed. Ocular and systemic manifestation and laboratory profiles were reviewed. Twenty-nine eyes of 16 consecutive patients (10 HIV-positive and 6 HIV-negative) were included. All patients were males, and mean age of onset for ocular syphilis was 43 (mean 42.65 ± 13.13). In both HIV-positive and HIV-negative groups, ocular manifestations of syphilis were variable including anterior uveitis (4 eyes), posterior uveitis (8 eyes), panuveitis (13 eyes), and isolated papillitis (4 eyes). In HIV-positive patients, panuveitis was the most common feature (12/18 eyes, 67 %) and serum rapid plasma reagin (RPR) titers were significantly higher (range 1:64-1:16,348; mean 1:768; p = 0.018) than in HIV-negative patients. Upon the diagnosis of ocular syphilis in HIV-positive patients, HIV-1 viral load was high (median 206,887 copies/ml) and CD4 cell count ranged from 127 to 535 cells/ml (mean 237 ± 142; median 137). Regardless of HIV status, cerebrospinal fluid (CSF) exam was frequently abnormal: positive CSF fluorescent treponemal antibody absorption (FTA-ABS) or Venereal Disease Research Laboratory (VDRL) test results in seven patients or either elevated CSF WBC count or elevated CSF protein in six patients. Our results reveal that the patients with ocular syphilis with high serum RPR titers may have concomitant HIV infection requiring further testing for HIV status and ocular syphilis is likely associated with the central nervous system involvement and therefore needs to be managed according to the treatment recommendations for

    Background Syphilis in pregnancy imposes a significant global health and economic burden. More than half of cases result in serious adverse events, including infant mortality and infection. The annual global burden from mother-to-child transmission (MTCT) of syphilis is estimated at 3.6 million disability-adjusted life years (DALYs) and $309 million in medical costs. Syphilis screening and treatment is simple, effective, and affordable, yet, worldwide, most pregnant women do not receive these services. We assessed cost-effectiveness of scaling-up syphilis screening and treatment in existing antenatal care (ANC) programs in various programmatic, epidemiologic, and economic contexts. Methods and Findings We modeled the cost, health impact, and cost-effectiveness of expanded syphilis screening and treatment in ANC, compared to current services, for 1,000,000 pregnancies per year over four years. We defined eight generic country scenarios by systematically varying three factors: current maternal syphilis testing and treatment coverage, syphilis prevalence in pregnant women, and the cost of healthcare. We calculated program and net costs, DALYs averted, and net costs per DALY averted over four years in each scenario. Program costs are estimated at $4,142,287 – $8,235,796 per million pregnant women (2010 USD). Net costs, adjusted for averted medical care and current services, range from net savings of $12,261,250 to net costs of $1,736,807. The program averts an estimated 5,754 – 93,484 DALYs, yielding net savings in four scenarios, and a cost per DALY averted of $24 – $111 in the four scenarios with net costs. Results were robust in sensitivity analyses. Conclusions Eliminating MTCT of syphilis through expanded screening and treatment in ANC is likely to be highly cost-effective by WHO-defined thresholds in a wide range of settings. Countries with high prevalence, low current service coverage, and high healthcare cost would benefit most. Future analyses can be

    Background To estimate probability of adverse pregnancy outcomes (APOs) among women with and without syphilis through a systematic review of published literatures. Methodology/Principal Findings Chinese and English literatures were searched for studies assessing pregnancy outcomes in the presence of maternal syphilis through August 2013. The prevalence estimates were summarized and analyzed by meta-analysis. Fifty-four literatures involving 11398 syphilitic women and 43342 non-syphilitic women were included from 4187 records initially found. Among untreated mothers with syphilis, pooled estimates were 76.8% for all APOs, 36.0% for congenital syphilis, 23.2% for preterm, 23.4% for low birth weight, 26.4% for stillbirth or fetal loss, 14.9% for miscarriage and 16.2% for neonatal deaths. Among syphilitic mother receiving treatment only in the late trimester (>28 weeks), pooled estimates were 64.4% for APOs, 40.6% for congenital syphilis, 17.6% for preterm, 12.4% for low birth weight, and 21.3% for stillbirth or fetal loss. Among syphilitic mothers with high titers (≥1∶8), pooled estimates were 42.8% for all APOs, 25.8% for congenital syphilis, 15.1% for preterm, 9.4% for low birth weight, 14.6% for stillbirth or fetal loss and 16.0% for neonatal deaths. Among non-syphilitic mothers, the pooled estimates were 13.7% for all APOs, 7.2% for preterm birth, 4.5% for low birth weight, 3.7% for stillbirth or fetal loss, 2.3% for miscarriage and 2.0% for neonatal death. Begg's rank correlation test indicated little evidence of publication bias (P>0.10). Substantial heterogeneity was found across studies in the estimates of all adverse outcomes for both women with syphilis (I 2 = 93.9%; Psyphilis (I 2 = 94.8%; PSyphilis continues to be an important cause of substantial perinatal morbidity and mortality, which reminds that policy-makers charged with resource allocation that the elimination of mother-to-child transmission of syphilis is a public health priority.

  2. A double-edged sword: does highly active antiretroviral therapy contribute to syphilis incidence by impairing immunity to Treponema pallidum?

    Recently, the world has experienced a rapidly escalating outbreak of infectious syphilis primarily affecting men who have sex with men (MSM); many are taking highly active antiretroviral therapy (HAART) for HIV-1 infection. The prevailing hypothesis is that HAART availability and effectiveness have led to the perception among both individuals who are HIV-1 infected and those who are uninfected that HIV-1 transmission has become much less likely, and the effects of HIV-1 infection less deadly. This is expected to result in increased sexual risk-taking, especially unprotected anal intercourse, leading to more non-HIV-1 STDs, including gonorrhoea, chlamydia and syphilis. However, syphilis incidence has increased more rapidly than other STDs. We hypothesise that HAART downregulates the innate and acquired immune responses to Treponema pallidum and that this biological explanation plays an important role in the syphilis epidemic. We performed a literature search and developed a mathematical model of HIV-1 and T. pallidum confection in a population with two risk groups with assortative mixing to explore the consequence on syphilis prevalence of HAART-induced changes in behaviour versus HAART-induced biological effects. Since rising syphilis incidence appears to have outpaced gonorrhoea and chlamydia, predominantly affecting HIV-1 positive MSM, behavioural factors alone may be insufficient to explain the unique, sharp increase in syphilis incidence. HAART agents have the potential to alter the innate and acquired immune responses in ways that may enhance susceptibility to T. pallidum . This raises the possibility that therapeutic and preventative HAART may inadvertently increase the incidence of syphilis, a situation that would have significant and global public health implications. We propose that additional studies investigating the interplay between HAART and enhanced T. pallidum susceptibility are needed. If our hypothesis is correct, HAART should be combined with

    This report evaluates the scientific literature on caffeine with respect to potential cardiovascular outcomes, specifically relative risks of total cardiovascular disease (CVD), coronary heart disease (CHD) and acute myocardial infarction (AMI), effects on arrhythmia, heart failure, sudden cardiac arrest, stroke, blood pressure, hypertension, and other biomarkers of effect, including heart rate, cerebral blood flow, cardiac output, plasma homocysteine levels, serum cholesterol levels, electrocardiogram (EKG) parameters, heart rate variability, endothelial/platelet function and plasma/urine catecholamine levels. Caffeine intake has been associated with a range of reversible and transient physiological effects broadly and cardiovascular effects specifically. This report attempts to understand where the delineations exist in caffeine intake and corresponding cardiovascular effects among various subpopulations. The available literature suggests that cardiovascular effects experienced by caffeine consumers at levels up to 600 mg/day are in most cases mild, transient, and reversible, with no lasting adverse effect. The point at which caffeine intake may cause harm to the cardiovascular system is not readily identifiable in part because data on the effects of daily intakes greater than 600 mg is limited. However, the evidence considered within this review suggests that typical moderate caffeine intake is not associated with increased risks of total cardiovascular disease; arrhythmia; heart failure; blood pressure changes among regular coffee drinkers; or hypertension in baseline populations.

    The competition for public cardiovascular research grants has recently increased. Independent researchers are facing increasing competition for public research grant support and ultimately may need to seek alternative funding sources. Crowdfunding, a financing method of raising funds online by pooling together small donations from the online community to support a specific initiative, seems to have significant potential. However, the feasibility of crowdfunding for cardiovascular research remains unknown. Here, we performed exploratory data analysis of the feasibility of online crowdfunding in cardiovascular research. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although huge and long-lasting research efforts have been spent on the development of new diagnostic techniques investigating cardiovascular diseases, still fundamental challenges exist; the main challenge being the diagnosis of a suspected or known coronary artery disease or its consequences (myocardial infarction, heart failure etc.). Beside morphological techniques, functional imaging modalities are available in clinical diagnostic algorithms, whereas molecular cardiovascular imaging techniques are still under development. This review summarizes clinical-diagnostical challenges of modern cardiovascular medicine as well as the potential of new molecular imaging techniques to face these. (orig.)

    Although detection of Treponema pallidum DNA in whole-blood specimens of syphilis patients has been reported, it is uncertain at what stage of the disease such specimens are most suitable for the molecular diagnosis of syphilis. Also, few studies have directly compared the different gene targets for routine laboratory diagnostic usage in PCR assays. We examined 87 specimens from 68 patients attending two urban sexually transmitted disease clinics in Alberta, Canada. PCR was used to amplify the T. pallidum tpp47, bmp, and polA genes as well as a specific region of the 23S rRNA gene linked to macrolide antibiotic susceptibility. In primary syphilis cases, PCR was positive exclusively (75% sensitivity rate) in ulcerative swabs but not in blood specimens, while in secondary syphilis cases, 50% of the blood specimens were positive by PCR. Four out of 14 (28.6%) of our PCR-positive syphilis cases were found to be caused by an azithromycin-resistant strain(s). Our results confirmed that swabs from primary ulcers are the specimens of choice for laboratory diagnostic purposes. However, further research is required to determine what specimen(s) would be most appropriate for molecular investigation of syphilis in secondary and latent syphilis. PMID:19339468

    To assess the impact of the Avahan HIV prevention programme for female sex workers (FSWs) in south India on reducing syphilis prevalence among their clients, by comparing rates of syphilis over time as reported in two large-scale surveys of FSWs' clients. A random-effect multilevel logistic regression analysis was performed using syphilis as the dependent variable, with individual independent variables (from the two survey rounds) at level 1 and the district-level programme (from the Avahan computerised monitoring and information system) and contextual variables (from Indian government datasets) at level 2. Programme variables included their 2006 value and their difference in value between 2008 and 2006, as well as the interaction between the latter and the study round. The analysis also controlled for baseline syphilis prevalence and its interaction with the study round. Syphilis decreased significantly among FSWs' clients, from 4.8% (round 1) to 2.6% (round 2), p<0.001. The OR of the interaction term between the difference in programme coverage of FSWs and the round was 0.98 (p=0.023), suggesting that increased coverage was associated with a reduced incidence of syphilis. This study suggests that the Avahan intervention programme among FSWs reduced syphilis rates among their clients. Published by the BMJ Publishing Group Limited.

    The availability of simple diagnostic methods may contribute to more efficient control of sexually transmitted diseases (STDs) in developing countries. For the detection of syphilis, a simple rapid plasma reagin (RPR) "teardrop" assay for finger-prick blood samples was developed in 1962. The reliability of this test is compared with RPR, Treponema pallidum hemagglutination assay (TPHA), and fluorescent treponemal antibody absorption (FTA-Abs) assays performed on venous blood samples. To evaluate the potential usefulness of the finger-stick RPR teardrop assay for diagnosis of syphilis in settings with poor medical resources. Pregnant women evaluated at two health centers in Pikine, Senegal were tested for STDs. The RPR teardrop assay was performed on plasma from blood samples obtained by finger prick, and standard RPR, TPHA, and FTA-Abs procedures were performed on serum obtained by vein puncture. The sensitivity and specificity of the finger-prick RPR teardrop assay were 69.7% and 96.5%, respectively, and its reactivity was correlated with RPR serum antibody titer. The finger-prick RPR teardrop assay is not a reliable alternative to the classic serum RPR test.

    In its initial years, the nascent Turkish republic established the Ministry of Health and Social Assistance in order to promote public health. Beyond simply facilitating its modernizing agenda for the emergent nation-state as it sought to define itself against an Ottoman past, this institution was also geared toward remedying a self-defined population crisis by prioritizing and confronting particular diseases and health conditions. One of the maladies of utmost concern was syphilis. Based upon an analysis of official primary sources, this article engages with how the developing republic distinguished and consequently politically constructed-or framed-the syphilis problem from the vantage of its new forward capital, Ankara. Integral to this project of confronting this sexually transmitted disease, public health officials projected upon both this ailment and their understanding of the suitable means for its treatment their own views of what constituted appropriate sexual practices and relations. In doing so, certain subgroups of the population, especially prostitutes, were particularized as targets for surveillance and policing through regimes of licensing and compulsory medical examinations. Stemming from the state's framing of the disease-and its definition of appropriate sexual practices-this article also examines the subsequent legislative and public health education projects that followed.

    Congenital syphilis (CS) is a preventable epidemic disease for which control is hindered by socioeconomic and health system issues. Inadequately treated maternal syphilis (MaS) commonly has serious adverse obstetric outcomes. This study - which is a cross-sectional study in a Brazilian large urban public Mother and Child hospital, making use of secondary data - evaluated the occurrence of treatment of sexual partners (SP) among women with MaS. The results showed that 771 MaS cases were identified from 2007 to 2014. No information on SP treatment was available in 570 (73.9%) cases. Of the 201 cases presenting information, 25 (12.4%) SP were treated. Out of 164 women having six or more prenatal visits, 25 (15.2%) SP received treatment. Data analyzed biennially have shown a growing trend of cases without collected information, ranging from 27.2% in 2007-2008 to 87.5% in 2013-2014. No linear trend in proportions of treated SP (maximum 7.4% SP treated) was found. Thus, in this study, it has been concluded that the proportion of SP adequately treated was consistently low, and the quality of information deteriorated during the studied period. Prenatal care per se, as provided, was not effective in delivering adequate treatment of SP. Creative integrated services with SP active participation are greatly needed if CS is to be controlled.

    Syphilis and HIV infections in pregnancy result in a number of adverse outcomes including neonatal death and vertical transmission. Ethiopia is a country where these infections are highly prevalent. However, data on co-morbidities of syphilis and HIV among pregnant women in Gondar are scarce. Thus, the aim of this study was to determine the seroprevalence of these infections and associated factors among pregnant women attending antenatal care at the University of Gondar teaching hospital, Northwest Ethiopia. A cross sectional study was conducted from February to June 2011. Structured interviews were used to collect socio-demographic and obstetric data. Sera against syphilis were screened by rapid plasma reagin test; and confirmed by Treponema pallidum hemagglutination assay. HIV infection was detected by rapid HIV test kits following the national algorithms for HIV testing. Data were summarized by descriptive statistics and binary logistic regression. Odds ratio (OR) and 95% confidence intervals (CI) were calculated. Of 385 pregnant women, reactive syphilis was noted in 11/385 (2.9%) and seroprevalence of HIV was 43/385 (11.2%). The prevalence of syphilis and HIV co-infection was 2/385(0.5%). High rate of syphilis was observed among the women with above 30 years of age (OR 3.69, 95% CI 0.83 - 16.82). Women with a history of miscarriage and stillbirth were more likely to be infected by syphilis (OR 2.22, 95% CI 0.54-9.60) and (OR 3.24, 95% CI 0.00-17.54), respectively. Our data indicated that syphilis and HIV infections are still important public health concerns among pregnant women in the Gondar area. Hence, we recommend strenuous screening of all pregnant women for these infections during antenatal care. Further, strengthening health education on the mode of transmission and prevention of HIV and syphilis is essential for effective control of these infections.

    Maternal syphilis is a health threat to both the pregnant women and the children. This study aimed to delineate the longitudinal trend of maternal syphilis and burden of associated adverse pregnant outcomes (APOs) in Shanghai from 2001 to 2015; and to evaluate the effects of preventing mother-to-child transmission (PMTCT) of syphilis in Shanghai with regard to service coverage and APOs averted. PMTCT program of syphilis has been implemented since 2001. Municipal and national PMTCT surveillance data were used in analysis. By using WHO estimation model, the burden of associated APOs and APOs averted were estimated. The differences in access to antenatal care and PMTCT services between resident and non-resident pregnant women were analyzed. The prevalence of seropositivity for maternal syphilis in Shanghai ranged from 0.20% to 0.38% during 2001-2015. The treatment rate varied from 69.8% to 96.8% and remained 83.6% in 2015. Under the PMTCT program, 2163 APOs had been averted during the 15-year period, including 852(39.4%) early fetal loss/stillbirth, 356(16.4%) neonatal death, 190(8.8%) prematurity or low birth weight, and 765(35.4%) clinical evidence of congenital syphilis. Compared with the residents, the non-resident pregnant women had a higher prevalence of syphilis (1.2‰ vs. 2.5‰) and contributed to 81.7% of the syphilis associated APOs in 2015. Screening of maternal syphilis has reached a full coverage both in residents and non-residents. Large numbers of APOs has been averted attributing to the PMTCT program. More attentions should be paid to those vulnerable non-resident pregnant women and tailored interventions including health education, PMTCT promotion and point of care should be given to maximize the effects of PMTCT in Shanghai.

    Men who have sex with men (MSM) in the United States experience an approximately 100-fold greater rate of primary and secondary (P&S) syphilis diagnoses compared with men who have sex with women only. As in the general population, racial/ethnic disparities in P&S syphilis diagnosis rates may exist among MSM, but MSM-specific P&S syphilis rates by race/ethnicity are unavailable. We enhanced a published modeling approach to estimate area-level MSM populations by race/ethnicity and provide the first estimates of P&S syphilis among black and white non-Hispanic MSM. We used data from the American Community Survey (ACS), published findings from the National Health and Nutrition Examination Survey (NHANES), and national syphilis surveillance data to estimate state-level rates of P&S syphilis diagnoses among MSM, overall and for black and white non-Hispanic MSM. We also used variability around ACS and NHANES estimates to calculate 95% confidence intervals for each rate. Among 11,359 cases of P&S syphilis among MSM with known race/ethnicity in 2014, 72.5% were among white (40.3%) or black (32.2%) MSM. The national rate of P&S syphilis diagnosis was 168.4/100,000 for white MSM and 583.9/100,000 for black MSM. Regional rates for black MSM ranged from 602.0/100,000 (South) to 521.5/100,000 (Midwest) and were consistently higher than those for white MSM. Although white MSM accounted for more P&S syphilis diagnoses than black MSM in 2014, when evaluating diagnoses based on rate per 100,000, black MSM had consistently and markedly higher rates than white MSM, with the highest impacted states located in the US South.

    The human treponematoses are important causes of disease. Mother-to-child transmission of syphilis remains a major cause of stillbirth and neonatal death. There are also almost 100 000 cases of endemic treponemal disease reported annually, predominantly yaws. Rapid diagnostic tests (RDTs) would improve access to screening for these diseases. Most RDTs cannot distinguish current and previous infection. The Dual Path Platform (DPP) Syphilis Screen & Confirm test includes both a treponemal (T1) and nontreponemal (T2) component and may improve the accuracy of diagnosis. We conducted a metaanalysis of published and unpublished evaluations of the DPP-RDT for the diagnosis of syphilis and yaws. We calculated the sensitivity, specificity, and overall agreement of the test compared with reference laboratory tests. Nine evaluations, including 7267 tests, were included. Sensitivity was higher in patients with higher titer rapid plasma reagin (≥1:16) for both the T1 (98.2% vs 90.1%, P syphilis and yaws, although the sensitivity is decreased at lower antibody titers. © The Author 2016.

    Introduction Syphilis and HIV screening is highly recommended for pregnant women and those at risk for infection. We used conjoint analysis to identify factors associated with testing preferences for HIV and syphilis infection. Methods We recruited 298 men and women 18 years and over seeking testing or care at GHESKIO (Haitian Study Group for Kaposi's Sarcoma and Opportunistic Infections) clinics. We created eight hypothetical dual HIV-syphilis test profiles varying across six dichotomous attributes. Participants were asked to rate each profile using Likert preference scales. An impact score was generated for each attribute by taking the difference between the preference scores for the preferred and non-preferred level of each attribute. Two-sided one-sample t-test was used to generate p values. Results Of 298 study participants, 61 (20.5%) were male. Of 237 females, 49 (20.7%) were pregnant. Cost (free vs. US$4; p syphilis testing preferences for this study sample in Port-au-Prince prioritized cost, single fingerprick, laboratory-based testing and timeliness.

    Full Text Available The current study presents some aspects of syphilis in the Balkan Peninsula from the 19th century until the Interwar. Ever since the birth of modern Balkan States (Greece, Bulgaria, Turkey and Serbia, urbanization, poverty and the frequent wars have been considered the major factors conducive to the spread of syphilis. The measures against sex work and sexually transmitted diseases (STDs were taken in two aspects, one medical and the other legislative. In this period, numerous hospitals for venereal diseases were established in the Balkan countries. In line with the international diagnostic approach and therapeutic standards, laboratory examinations in these Balkan hospitals included spirochete examination, Wassermann reaction, precipitation reaction and cerebrospinal fluid examination. Despite the strict legislation and the adoption of relevant laws against illegal sex work, public health services were unable to curb the spread of syphilis. Medical and social factors such as poverty, citizen’s ignorance of STDs, misguided medical perceptions, lack of sanitary control of prostitution and epidemiological studies, are highlighted in this study. These factors were the major causes that helped syphilis spread in the Balkan countries during the 19th and early 20th century. The value of these aspects as a historic paradigm is diachronic. Failure to comply with the laws and the dysfunction of public services during periods of war or socioeconomic crises are both factors facilitating the spread of STDs.

    In patients with acromegaly, chronic excess of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) leads to the development of acromegalic cardiomyopathy. Its main features are biventricular hypertrophy, diastolic dysfunction, and in later stages, systolic dysfunction and congestive heart failure. Surgical and/or pharmacological treatment of acromegaly and control of cardiovascular risk factors help reverse some of these pathophysiologic changes and decrease the high risk of cardiovascular complications.

    Objective: To investigate the factors associated with syphilis/HIV infection among men who have sex with men (MSM) maintaining a single sexual partner in Shenzhen. Methods: Respondent driven sampling and snowball sampling method were used to recruit MSM receiving voluntary counseling and testing in Shenzhen Rainbow clinic from 2011 to 2016. aged 18 years and above; reported having one or more anal sexual partners in the recent 6 months. A total of 3 109 men who have sex with men (MSM) were involved in the study. Questionnaire-based interviews were conducted on a one-on-one basis. Data were collected including socio-demographic information, human immunodeficiency virus (HIV) testing history, history of blood donation and drug abuse in the recent two years, self-identified sexual orientation, role in homosexual behavior, ever being money boys (MB) and clients of MB, female sexual partners in the recent 6 months. 5 ml blood samples were taken after questionnaires. Syphilis was screened using toluidine red unheated serum test for the antibody of treponema pallidum and then confirmed by treponema pallidum particle assay. The enzyme-linked immunosorbent assay (ELISA) was used for screening HIV and western blot was used to confirm the HIV screening results. The difference of condom use among MSM between female sexual partners and male sexual partners were compared. Multivariate unconditional stepwise logistic regression model was used to analyze factors associated with syphilis infection and HIV positive among MSM. Results: A total of 3 109 eligible participants with mean (SD) age of 31.49 (8.64) years were enrolled in this study. Among them, 565 cases were infected with syphilis (18.17%), 330 cases were infected with HIV (10.61%), and 165 cases (5.31%) were syphilis co-infected with HIV. 791 (25.44%) reported maintaining a single sexual partners in the recent 6 months.

    Although the advantages of introducing point of care testing for syphilis in antenatal care (ANC) are well documented, there is little evidence on how to address structural issues within health systems. A better understanding of how these interventions work in a range of settings and contexts is needed in order to overcome bottlenecks at health system level. To better understand the relationships between implementation and context we developed and implemented an intervention focused on integrating a rapid screening test for syphilis in ANC services in rural primary health care facilities in Burkina Faso. This manuscript describes the intervention and reports on feasibility and acceptability of the intervention, the facilitators and barriers to the implementation of this intervention and the likelihood that point of care test for syphilis will become routinely incorporated in practice. In Kaya Health and Demographic Surveillance System (Kaya HDSS), all 7 primary healthcare facilities were selected for intervention in 2013. A participatory approach was used to design and implement an antenatal syphilis screening intervention. The Normalization Process Model (NPM) proposed by May et al. was adapted in order to identify barriers and facilitators and to explore the likelihood to become routinely incorporated in practice. Registers, Observations (n = 14 ANC 1) of interactions between patients and health workers during ANC and interviews with health workers (n = 14) were our data sources. An intervention that included onsite training, provision of supplies and medicines, quality control and supervision was implemented in 7 health facilities in 2013. Rapid syphilis test and treatment were delivered during ANC within the examination room with no specific additional mechanism regarding staff organization. The perceived barriers were lack of training of all staff, workload, stock-outs of consumables and lack of motivation of staff. Key facilitators included political

    The recent upsurge of syphilis infections among men who have sex with men (MSM) is one of the major challenges facing China. However, the overall burden is still not clear. This study aims to summarize the incidence of syphilis among MSM in China by using meta-analysis. We comprehensively searched PubMed-MEDLINE, China National Knowledge Infrastructure and Chinese Wanfang databases. Articles published between December 2009 and March 2015 that met the inclusion criteria were considerably involved in this meta-analysis. Two reviewers performed a quality assessment of the studies and extracted data for estimating the overall syphilis incidence. STATA 12.0 was used to summarize the overall incidence of syphilis. In all, 14 studies from 13 papers were included in this study. Follow-up duration of these studies ranged from six to 36 months, while drop-out rates ranged from 11.9% to 83.6%. The individual incidence rates of the included studies varied from 3.1/100 person-years (95% CI, 0.8-5.3/100 person-years) to 38.5/100 person-years (95% CI, 28.9-48.1/100 person-years), with a pooled incidence of 9.6/100 person-years (95% CI, 7.0-12.2/100 person-years). The subgroup meta-analysis revealed that incidence estimates were 38.5/100 person-years (95% CI, 28.9-48.1/100 person-years), 12.1/100 person-years (95% CI, 7.0-17.2/100 person-years), 11.2/100 person-years (95% CI, 0.7-23.1/100 person-years), 8.9/100 person-years (95% CI, 6.5-11.2/100 person-years), 5.7/100 person-years (95% CI, 3.4-8.0/100 person-years) and 3.1/100 person-years (95% CI, 0.8-5.3/100 person-years) in Northeast, North, Southwest, East, South and Northwest China, respectively. Syphilis incidence among Chinese MSM is high, and this may increase the spread of other sexually transmitted infections, including human immunodeficiency virus. It is essential to integrate syphilis control programs with HIV control programs. This can be achieved by establishing public health response systems to monitor and control

Sin embargo, no todas las modificaciones presentadas se asocian con deterioro en la función. Entre los cambios a nivel cardiaco se tienen: disminución en el número de miocitos y en las células del sistema de conducción cardiaca, desarrollo de fibrosis, cambios en el transporte de calcio a través de las membranas y disminución del cronotropismo, inotropismo y lusitropismo mediados por estímulo b-adrenérgico. A nivel vascular, hay incremento en la rigidez de la pared de las arterias, con aumento en la velocidad de la onda de pulso, disfunción endotelial y disminución de la vasodilatación mediada por estímulo b-adrenérgico. Durante el reposo el sistema cardiovascular es capaz de desarrollar mecanismos adaptativos eficientes, pero en situaciones de estrés como el ejercicio, los cambios asociados con el envejecimiento se hacen evidentes ya que está disminuida la capacidad para obtener la frecuencia cardiaca máxima, está incrementada la postcarga y hay disminución de la contractilidad intrínseca. Por lo anterior, los ancianos deben utilizar al máximo el mecanismo de Frank-Starling para mantener el gasto cardiaco.

Seu agente etiológico, o Treponema pallidum, nunca foi cultivado e, apesar de descrito há mais de 100 anos e sendo tratado desde 1943 pela penicilina, sua droga mais eficaz, continua como um problema de saúde importante em países desenvolvidos ou subdesenvolvidos. Dadas as características da forma de transmissão, a doença acompanhou as mudanças comportamentais da sociedade e nos últimos anos tornou-se mais importante ainda devido à possibilidade de aumentar o risco de transmissão da síndrome de imunodeficiência adquirida. Novos testes laboratoriais e medidas de controle principalmente voltadas para o tratamento adequado do paciente e parceiro, uso de preservativo, informação à população fazem parte das medidas adotadas para controle da sífilis pelos responsáveis por programas de saúde.Syphilis is an infectious disease transmitted through sex or vertically during pregnancy. It is characterized by periods of activity and latency, disseminated systemic involvement, and progression to acute complications in patients that remain untreated or have been inadequately treated. Syphilis is known since the 15th century and studied by all medical specialties, particularly by Dermatology. The etiologic agent Treponema pallidum has never been cultured and was described over 100 years ago. The disease has been effectively treated with penicillin since 1943, but it remains an important health problem in developed and developing countries. Given its transmission characteristics, the condition has

    The FTA test was developed at a time when immunofluorescence procedures were not well-defined. Through technique control and research, a modification of the FTA test, the FTA-ABS, has attained a position as one of the leading treponemal tests to confirm the reagin tests for syphilis. In this review of the FTA-ABS test, attention has been focused on reagent development, with the anticipation that reagent standardization may soon become a reality. The T. pallidum antigen obtained by extracting infected rabbit testicular tissue has evolved from a preparation in which the treponemes remained in the initial extracting fluid to a reagent that can be free of rabbit tissue and globulin. These washed antigen preparations improve visibility of the treponemes on the microscope slide, reduce background fluorescence, and reduce or prevent from occurring nonspecific reactions that are a result of tissue and globulin components. Both washed and nonwashed antigens are available commercially, and, to date, little differentiation has appeared on the product label. The predominant immunoglobulin that reacts with T. pallidum in the indirect fluorescent antibody tests appears to be IgG. This is the major immunoglobulin detected in the FTA-ABS test. IgM, although increased in early syphilis, is also increased in other clinical conditions. Several reports suggest that adult IgM detection in the present FTA-ABS test would be nonspecific. Until specific IgM antibody in adult syphilis can be detected without a risk to test specificity, the conjugate for the FTA-ABS test should continue to be an anti-IgG reagent. Class-specific, anti-IgG reagents are more expensive than other reagents; however, their use may eliminate the problem of nonspecificity resulting from IgM detection. Additionally, micromethods can be used to reduce cost, and this possibility should be investigated. The sorbent that contains an antigen to the Reiter treponeme may or may not specifically absorb the reactivity that

    Full Text Available Diabetes is a well-known risk factor of cardiovascular morbidity and mortality, and the beneficial effect of improved glycemic control on cardiovascular complications has been well established. However, the rosiglitazone experience aroused awareness of potential cardiovascular risk associated with diabetes drugs and prompted the U.S. Food and Drug Administration to issue new guidelines about cardiovascular risk. Through postmarketing cardiovascular safety trials, some drugs demonstrated cardiovascular benefits, while some antidiabetic drugs raised concern about a possible increased cardiovascular risk associated with drug use. With the development of new classes of drugs, treatment options became wider and the complexity of glycemic management in type 2 diabetes has increased. When choosing the appropriate treatment strategy for patients with type 2 diabetes at high cardiovascular risk, not only the glucose-lowering effects, but also overall benefits and risks for cardiovascular disease should be taken into consideration.

    Full Text Available Untreated syphilis in pregnancy is associated with adverse clinical outcomes to the infant. In low- and middle-income countries in Asia and Latin America, 20%-30% of women are not tested for syphilis during pregnancy. We evaluated the cost-effectiveness of increasing the coverage for antenatal syphilis screening in 11 Asian and 20 Latin American countries, using a point-of-care immunochromatographic strip (ICS test.The decision analytical cost-effectiveness models reported incremental costs per disability-adjusted life years (DALYs averted from the perspectives of the national health care payer. Clinical outcomes were stillbirths, neonatal deaths, and congenital syphilis. DALYs were computed using WHO disability weights. Costs included the ICS test, three injections of benzathine penicillin, and nurse wages. Country-specific inputs included the antenatal prevalence of syphilis and the proportion of women in the antenatal care setting that are screened for syphilis infection as reported in the 2014 WHO baseline report on global sexually transmitted infection surveillance. Country-specific data on the annual number of live births, proportion of women with at least one antenatal care visit, and per capita gross national income were also included in the model.The incremental cost/DALY averted of syphilis screening is US$53 (range: US$10-US$332; Prob<1*per capita GDP=99.71% in Asia and US$60 (range: US$5-US$225; Prob<1*per capita GDP=99.77% in Latin America. Universal screening may reduce the annual number of stillbirths by 20,344 and 4,270, neonatal deaths by 8,201 and 1,721, cases of congenital syphilis by 10,952 and 2,298, and avert 925,039 and 197,454 DALYs in the aggregate Asian and Latin American panel, respectively.Antenatal syphilis screening is highly cost-effective in all the 11 Asian and 20 Latin American countries assessed. Our findings support the decision to expand syphilis screening in countries with currently low screening rates or

    Objective: To understand the prevalence rates of HIV-syphilis and HIV-herpes simplex virus 2 (HSV-2) co-infections and related factors among men having sex with men (MSM) who had visited the voluntary HIV counseling and testing (VCT) clinics in Shanghai, China. Methods: 756 eligible MSM who attended the VCT clinics of Shanghai Municipality and Putuo district during March to August, 2015 were recruited to participate in a cross-sectional survey with questionnaire interview and blood testing for HIV, syphilis and HSV-2. Results: A total of 732 participants completed a valid questionnaire survey. The prevalence rates were 3.3 % (24/732) for HIV/Syphilis co-infection, 1.9 % (14/732) for HIV/HSV-2 co-infection, and 0.7 % (5/732) for HIV/Syphilis/HSV-2 co-infection, respectively. HIV prevalence appeared significantly higher among syphilis-infected participants (45.3 % , 24/53) than those without Syphilis (7.2 % , 61/679) (χ(2)=63.11, P Syphilis co-infection. Those participants who had high middle school or lower levels of education ( OR =6.87, 95 %CI : 1.86-25.42; OR =9.82, 95 %CI : 2.25-42.85) were under risk on HIV and HSV-2 co-infection. Conclusion: HIV/Syphilis and HIV/HSV-2 co-infection were seen among MSM who attended the VCT clinics in Shanghai that called for special attention, especially on migrants, those with low education or illicit drug users.

    Background The HIV-epidemic among MSM in China has worsened. In this key population, prevalence of HSV-2 and syphilis infection and co-infection with HIV is high. Methods A longitudinal study was conducted (n = 962) in Beijing, China, with three overlapping cohorts (n = 857, 757 and 760) consisting of MSM that were free from pairs of infections of concern (i.e. HIV-HSV-2, HIV-syphilis, HSV-2-syphilis) at baseline to estimate incidence of HIV, HSV-2, syphilis, and those of co-infection. Results The incidence of HIV, HSV-2 and syphilis in the overall cohort was 3.90 (95% CI = 2.37, 5.43), 7.87 (95% CI = 5.74, 10.00) and 6.06 (95% CI = 4.18, 7.94) cases per 100 person-years (PYs), respectively. The incidence of HIV-HSV-2, HIV-Syphilis and HSV-2-Syphilis co-infections was 0.30 (95% CI = 0.29, 0.88), 1.02 (95% CI = 0.13, 2.17) and 1.41 (95% CI: 0.04, 2.78) cases per 100 PYs, respectively, in the three sub-cohorts constructed for this study. Conclusions The incidence of HIV, HSV-2 and syphilis was very high and those of their co-infections were relatively high. Such co-infections have negative impacts on the HIV/STI epidemics. Prevention practices need to take such co-infections into account. PMID:26820145

    There is increasing evidence for a protective effect of tea consumption against cardiovascular disease. This review summarizes the available epidemiological data providing evidence for and against such an effect. We also review observational and intervention studies that investigated an effect of tea and tea extracts on cardiovascular risk factors, including blood pressure, serum lipids, diabetes mellitus, and obesity. Finally, we review potential mechanisms of benefit, including anti-inflammatory, anti-oxidant, and anti-proliferative effects, as well as favorable effects on endothelial function. Overall, the observational data suggest a benefit, but results are mixed and likely confounded by lifestyle and background dietary factors. The weight of evidence indicates favorable effects on risk factors and a number of plausible mechanisms have been elucidated in experimental and translational human studies. Despite the growing body evidence, it remains uncertain whether tea consumption should be recommended to the general population or to patients as a strategy to reduce cardiovascular risk.

  14. Making Sense of Pain: Delusions, Syphilis, and Somatic Pain in London County Council Asylums, c. 1900

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available During the late nineteenth century, a high percentage of male deaths in asylums was attributed to various forms of tertiary syphilis, most notably General Paralysis of the Insane (GPI and tabes dorsalis. It was not unusual for patients to present symptoms of both conditions, the latter of which could be agonizingly painful. Some patients also suffered from persecutory delusions, believing that electricity was running through them or that their limbs were gnawed by lions and wolves at night. Drawing on a theory advanced by a number of key alienists and pathologists of the period, I suggest that these delusions were misinterpretations of felt sensations and, as such, illusions rather than delusions. Despite the well-known problems around using these historical sources, I contend that recorded delusions in asylum case notes can be treated as narratives of pain that provide invaluable insights into patients' subjective experiences.

    Full Text Available Miss Evers' Boys (1997 is a movie based on a real fact happened in the State of Alabama (United States, where it was carried out a research work that begun in 1932 and was prolonged up to 1972. It consisted on watching the evolution of syphilis in black male patients, who were not given any anti-syphilitic treatment at any moment. Once the fact was public, a great polemic on the ethics of the research with human fellows was originated and publications dealt with this case. The movie, faithful as for the bottom of the problem, it’s made as a novel about a research team’s nurse and four black participants patients.

    Full Text Available Nonconvulsive status epilepticus (NCSE has been increasingly recognized as a cause of impaired level of consciousness in the ICU and emergency rooms. The confirmation of NCSE is largely based on the EEG, given the nonspecific and pleomorphic clinical manifestations. Debate remains over electroencephalograms (EEG criteria for NCSE. Periodic lateralized epileptiform discharges (PLEDs, have sparked controversy with regard to being part of the ictal vs. interictal spectrum. We report a case of a patient with syphilis who had cognitive decline and damaged consciousness with PLEDs and T2 hyperintensity at temporal and occipital lobe in MRI. After antiepileptic treatment only, his consciousness improved markedly together with the EEG in few days, while the change of MRI was still serious. In this case PLEDs is the sign of NCSE and change of MRI is limbic encephalitis (LE. This report discusses the association of PLEDs and NCSE, and supports the concept of PLEDs as an ictal pattern in some condition.

    Merins, V; Hahn, K

    2015-10-07

    Neurosyphilis might be difficult to diagnose particularly in asymptomatic patients and patients with HIV-coinfection. The objective of this study was to evaluate current diagnostic standards for neurosyphilis in HIV-positive and -negative patients. We studied retrospectively patients with an active syphilis infection who had additionally undergone lumbar puncture. Patients where the criteria for the diagnosis of a definite or probable neurosyphilis were applicable were further analyzed for clinical symptoms, CSF, HIV-status as well as Treponema pallidum testing in serum and CSF. Correlation analysis of categorical variables was done by using the Chi-square test or in cases of small sample sizes the exact test of Fisher. p values ≤0.05 were considered significant. Eighty-nine patients were diagnosed with syphilis. All necessary criteria for the diagnosis of a neurosyphilis were available in 67 of them including 35 HIV-positive and 32 HIV-negative patients. A definite neurosyphilis could be retrospectively diagnosed in 13 and a probable in another 25 cases. Normal CSF results were more likely in HIV-negatives (p = 0.016). A neurosyphilis was correlated to a CSF pleocytosis > 5 cells/µl and to an albumin quotient >7.8 mg/dl regardless of a parallel HIV infection. HIV-positives had more frequently a CSF-RPR titre >1:4 than HIV-negatives (p = 0.031). However, the RPR test in CSF in definite or probable neurosyphilis had a sensitivity of only 21 %. Our data show that a pleocytosis and an elevated albumin quotient correlate with neurosyphilis. However, the CSF-RPR test as gold standard in neurosyphilis diagnostics has a very low sensitivity.

    Penicillin is the gold standard for treating syphilis. However, allergic reactions, poor drug tolerance and limited efficacy in patients remain a challenging problem. The objective of this meta-analysis was to compare the efficacy of ceftriaxone and penicillin based on data obtained from published randomised controlled trials (RCTs). The Cochrane Library, Medline, EBSCO, EMBASE and Ovid databases were searched for RCTs of ceftriaxone vs. penicillin for the treatment of syphilis. Estimated risk ratios (RRs) and 95% confidence intervals (CIs) were used to investigate the following outcome measures: 3-month response rate; 6-month response rate; 12-month response rate; relapse rate; serofast rate; and failure rate. Seven RCTs involving 281 participants (159 patients who received ceftriaxone and 122 patients who received penicillin) were included in the meta-analysis. There were no significant differences in 3-month response rate (RR=1.12, 95% CI 0.89-1.42), 6-month response rate (RR=1.02, 95% CI 0.75-1.38), 12-month response rate (RR=1.04, 95% CI 0.82-1.32), relapse rate (RR=0.91, 95% CI 0.45-1.84), serofast rate (RR=0.69, 95% CI 0.22-2.12) or failure rate (RR=0.66, 95% CI 0.03-15.76) in patients treated with ceftriaxone compared with those treated with penicillin. In conclusion, there is no evidence in the literature that ceftriaxone is less efficient than penicillin. Copyright © 2015 Elsevier B.V. and the International Society of Chemotherapy.

    2003-09-20

    Chlamydia trachomatis (CT) pharyngitis has rarely been described in the literature. Studies in the last decade have shown a prevalence of less than 5%, with more women than men infected in the pharynx. Among homosexual men, only one study, conducted more than 5 years ago, detected the presence of CT in the throat (in one patient out of 13 tested). A 33 year-old homosexual man consulted for cutaneous lesions on the palms and the chest. Infected by HIV, he was taking antiretroviral therapy but no antibiotic prophylaxis. He admitted practising unprotected (insertive and receptive) fellatio with unknown partners. The lesions were those of secondary syphilis but the location of the chancre remained unknown. An enlarged screening for sexually transmitted infections detected the presence, through molecular amplification, of CT in the throat without further localisation (urethra, anus). After intramuscular injection of Extencillin and an 8-day-regimen of cycline, CT was no longer detected in the throat. The course of HIV infection did not appear modified by this infectious episode. According to a review of the literature, the 4 most recent studies have not revealed CT in the throat of homosexuals although the bacteria was detected in the urethra of 3 to 4% of them. Chlamydia trachomatis is more frequently detected in the genital tract rather than the pharynx of women also screened in various localisations. These results must be tempered by the participant recruitment methods, diagnostic methods used, sample size and history of recent antibiotherapy. The pharyngeal mucosa might be less receptive to CT than the urethral mucosa. Association of CT pharyngitis with syphilis or its occurrence during HIV infection are not documented. The molecular amplification technique detects CT in the throat with sensitivity and specificity. A one-week regimen of cycline can cure this pharyngitis. Cost-effectiveness of screening for pharyngeal CT has not yet been assessed in persons 'at risk'.

    Syphilis testing conventionally relies on a combination of non-treponemal and treponemal tests. The primary objective of this study was to describe the positive predictive value (PPV) of a screening algorithm in a combination of a treponemal rapid diagnostic test (RDT) and rapid plasma reagin (RPR) test at Komfo Anokye Teaching Hospital (KATH), Ghana. From February 2014 to January 2015, 5 mL of venous blood samples were taken from 16 016 blood donors and tested with a treponemal RDT; 5 mL of venous blood was taken from 526 consenting initial syphilis sero-reactive blood donors. These RDT reactive samples were confirmed with an algorithm, applying the Vitros ® /Abbott-Architect ® algorithm as gold standard. A total of 478 of 526 RDT reactive donors were confirmed positive for syphilis, making a PPV of 90·9%. Of the 172 (32·7%) donors who were also RPR positive, 167 were confirmed, resulting in a PPV of 97·1%. The PPV of the combined RDT and RPR (suspected active syphilis) testing algorithm was highest among donors at an enhanced risk of syphilis, family/replacement donors (99·9%), and among voluntary donors above 25 years (98·6%). Screening of blood donors by combining syphilis RDT and RPR with relatively good PPV may provide a reasonable technology for LMIC that has a limited capacity for testing and can contribute to the improvement of blood safety with a minimal loss of donors. © 2016 British Blood Transfusion Society.

    The lack of Treponema pallidum-specific antigens with highly accurate diagnosis makes the diagnosis of syphilis challenging. A soluble recombinant version of a new diagnostic protein Tp0663 has been produced. The serodiagnostic potential of this protein was assessed by screening 3326 serum samples simultaneously evaluated by rapid plasma reagin and T. pallidum particle agglutination tests. Kappa (κ) coefficients were used to compare the concordance between clinical diagnosis and the Tp0663-based ELISA or the ARCHITECT Syphilis TP chemiluminescent immunoassay (Abbott GmbH and Co. KG). Using the results of clinical diagnosis as the gold standard, the sensitivity and specificity of Tp0663 were found to be 98.83% (95% confidence interval (CI) 96.61-99.60%) and 100% (95% CI 99.88-100%), respectively. In comparison, the ARCHITECT Syphilis TP assay was found to have a lower sensitivity (97.27%, 95% CI 94.46-98.67%) and specificity (99.61%, 95% CI 99.32-99.78%). In particular, the ARCHITECT Syphilis TP exhibited a false-positive rate of 0.39%. Moreover, the ELISA was in perfect agreement with the gold standard, with a κ value of 0.99, comparable to that of ARCHITECT Syphilis TP (0.96). These results identified Tp0663 as a novel serodiagnostic candidate with great potential for developing novel tests for the diagnosis of syphilis. Copyright © 2015 The Authors.

    2017-10-01

    An article by Darby disparaging male circumcision (MC) for syphilis prevention in Victorian times (1837-1901) and voluntary medical MC programs for HIV prevention in recent times ignores contemporary scientific evidence. It is one-sided and cites outlier studies as well as claims by MC opponents that support the author's thesis, but ignores high quality randomised controlled trials and meta-analyses. While we agree with Darby that risky behaviours contribute to syphilis and HIV epidemics, there is now compelling evidence that MC helps reduce both syphilis and HIV infections. Although some motivations for MC in Victorian times were misguided, others, such as protection against syphilis, penile cancer, phimosis, balanitis and poor hygiene have stood the test of time. In the absence of a cure or effective prophylactic vaccine for HIV, MC should help lower heterosexually acquired HIV, especially when coupled with other interventions such as condoms and behaviour. This should save lives, as well as reducing costs and suffering. In contrast to Darby, our evaluation of the evidence leads us to conclude that MC would likely have helped reduce syphilis in Victorian times and, in the current era, will help lower both syphilis and HIV, so improving global public health.

    Full Text Available Currently, the efficacy of syphilis treatment is measured with anti-lipid antibody tests. These can take months to indicate cure and, as a result, syphilis treatment trials require long periods of follow-up. The causative organism, Treponema pallidum (T. pallidum, is detectable in the infectious lesions of early syphilis using DNA amplification. Bacteraemia can likewise be identified, typically in more active disease. We hypothesise that bacterial clearance from blood and ulcers will predict early the standard serology-measured treatment response and have developed a qPCR assay that could monitor this clearance directly in patients with infectious syphilis. Patients with early syphilis were given an intramuscular dose of benzathine penicillin. To investigate the appropriate sampling timeframe samples of blood and ulcer exudate were collected intensively for T. pallidum DNA (tpp047 gene and RNA (16S rRNA quantification. Sampling ended when two consecutive PCRs were negative. Four males were recruited. The mean peak level of T. pallidum DNA was 1626 copies/ml whole blood and the mean clearance half-life was 5.7 hours (std. dev. 0.53. The mean peak of 16S rRNA was 8879 copies/ml whole blood with a clearance half-life of 3.9 hours (std. dev. 0.84. From an ulcer, pre-treatment, 67,400 T. pallidum DNA copies and 7.08 x 107 16S rRNA copies were detected per absorbance strip and the clearance half-lives were 3.2 and 4.1 hours, respectively. Overall, T. pallidum nucleic acids were not detected in any sample collected more than 56 hours (range 20-56 after treatment. All patients achieved serologic cure. In patients with active early syphilis, measuring T. pallidum levels in blood and ulcer exudate may be a useful measure of treatment success in therapeutic trials. These laboratory findings need confirmation on a larger scale and in patients receiving different therapies.

  7. Comparative effectiveness of single and dual rapid diagnostic tests for syphilis and HIV in antenatal care services in Colombia

    Hernando Guillermo Gaitán-Duarte

    Full Text Available ABSTRACT Objective To assess the effectiveness of a dual rapid test compared to a single rapid test for syphilis and HIV screening. Methods A cluster-randomized open-label clinical trial was performed in 12 public antenatal care (ANC centers in the cities of Bogotá and Cali, Colombia. Pregnant women who were over 14 years of age at their first antenatal visit and who had not been previously tested for HIV and syphilis during the current pregnancy were included. Pregnant women were randomized to single HIV and single syphilis rapid diagnostic tests (Arm A or to dual HIV and syphilis rapid diagnostic tests (Arm B. The four main outcomes measured were: (1 acceptability of the test, (2 uptake in testing, (3 treatment on the same day (that is, timely treatment, and (4 treatment at any time for positive rapid test cases. Bivariate and multivariate analyses were calculated to adjust for the clustering effect and the period. Results A total of 1 048 patients were analyzed in Arm A, and 1 166 in Arm B. Acceptability of the rapid tests was 99.8% in Arm A and 99.6% in Arm B. The prevalence of positive rapid tests was 2.21% for syphilis and 0.36% for HIV. Timely treatment was provided to 20 of 29 patients (69% in Arm A and 16 of 20 patients (80% in Arm B (relative risk (RR, 1.10; 95% confidence interval (CI: (1.00 −1.20. Treatment at any time was given to 24 of 29 patients (83% in Arm A and to 20 of 20 (100% in Arm B (RR, 1.11; 95% CI: 1.01−1.22. Conclusions There were no differences in patient acceptability, testing and timely treatment between dual rapid tests and single rapid tests for HIV and syphilis screening in the ANC centers. Same-day treatment depends also on the interpretation of and confidence in the results by the health providers.

    Full Text Available Abstract Background Prisons are known to be high-risk environments for the spread of bloodborne and sexually transmitted infections. Prison officers are considered to have an intermittent exposure potential to bloodborne infectious diseases on the job, however there has been no studies on the prevalence of these infections in prison officers in Ghana. Methods A national multicenter cross-sectional study was undertaken on correlates of human immunodeficiency virus (HIV, hepatitis B virus (HBV, hepatitis C virus (HCV, and syphilis infections in sample of prison inmates and officers from eight of ten regional central prisons in Ghana. A total of 1366 inmates and 445 officers were enrolled between May 2004 and December 2005. Subjects completed personal risk-factor questionnaire and provided blood specimens for unlinked anonymous testing for presence of antibodies to HIV, HCV and Treponema pallidum; and surface antigen of HBV (HBsAg. These data were analyzed using both univariate and multivariate techniques. Results Almost 18% (1336 of 7652 eligible inmates and 21% (445 of 2139 eligible officers in eight study prisons took part. Median ages of inmates and officers were 36.5 years (range 16–84 and 38.1 years (range 25–59, respectively. Among inmates, HIV seroprevalence was 5.9%, syphilis seroprevalence was 16.5%, and 25.5% had HBsAg. Among officers tested, HIV seroprevalence was 4.9%, HCV seroprevalence was 18.7%, syphilis seroprevalence was 7.9%, and 11.7% had HBsAg. Independent determinants for HIV, HBV and syphilis infections among inmates were age between 17–46, being unmarried, being illiterate, female gender, being incarcerated for longer than median time served of 36 months, history of homosexuality, history of intravenous drug use, history of sharing syringes and drug paraphernalia, history of participation in paid sexual activity, and history of sexually transmitted diseases.

    Syphilis remains as a worldwide public health problem; hence, it is necessary to develop a new diagnostic approach that is easier and faster than conventional tests. A new testing method to detect Treponema pallidum IgM (TP-IgM), named colloidal gold immunochromatography assay (GICA), is presented in place of fluorescent treponemal antibody absorption (FTA-Abs). TP-IgM was detected using GICA developed on syphilis-specific recombinant proteins TPN17 and TPN47. The FTA-Abs IgM test was set as the gold standard. A GICA TP-IgM test was performed to detect syphilis in 1208 patients who received recommended therapy for syphilis for more than 1 year at the Xiamen Center of Clinical Laboratory in China from June 2005 to May 2009. One hundred blood donors were set up as control. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were 98.21%, 99.04%, 93.75%, 99.73%, 102.3, and 0.018, respectively. Detection on 500 interference specimens indicated that the biological false-positive rate of the GICA test was extremely low and was free from other biological and chemical factors. The patients were divided into the following experimental groups based on the results of toluidine red unheated serum test (TRUST) and treponemal pallidum particle agglutination (TPPA): (1) the syphilis serofast reaction (SSR) group consisted of 411 cases with (+) TRUST and (+) TPPA, which exhibited no clinical manifestations of syphilis after 1 year of recommended syphilis treatment; (2) the serum cure group, which was further subdivided into group A, a group that consisted of 251 cases with (-) TRUST and (+) TPPA, and (3) group B, a group that consisted of 546 cases with (-) TRUST and (-) TPPA; and (4) the blood donor control group, which consisted of 100 healthy persons with (-) ELISA-TP and (-) TPPA. We used the FTA-Abs method and the GICA method to detect TP-IgM; the positive rate of TP-IgM in 411 SSR

    One patient complained of persisting diffuse bone pain, with greater intensity in the pelvis. HDP {sup 99m}Tc bone scintigraphy showed increased uptake around the right sacro-iliac joint and in the right iliac area due to increased osteoblastic activity, thereby providing functional information about the evolutive nature of the bone lesion. The X-scanner only revealed osteolysis in the same location. A blood test confirmed the diagnosis of tertiary syphilis. (author)

    A multitude of studies have been published on the relationship between cardiovascular disease risk and a variety of nutrients, foods, and dietary patterns. Despite the well-accepted notion that diet has a significant influence on the development and prevention of cardiovascular disease, the foods considered healthy and harmful have varied over the years. This review aims to summarize the current scientific evidence on the cardioprotective effect of those foods and nutrients that have been considered healthy as well as those that have been deemed unhealthy at any given time in history. For this purpose, we reviewed the most recent literature using as keywords foods and nutrients (ie, meat, omega-3) and cardiovascular disease-related terms (ie, cardiovascular diseases, stroke). Emphasis has been placed on meta-analyses and Cochrane reviews. In general, there is a paucity of intervention studies with a high level of evidence supporting the benefits of healthy foods (ie, fruits and vegetables), whereas the evidence supporting the case against those foods considered less healthy (ie, saturated fat) seems to be weakened by most recent evidence. In summary, most of the evidence supporting the benefits and harms of specific foods and nutrients is based on observational epidemiological studies. The outcome of randomized clinical trials reveals a more confusing picture with most studies providing very small effects in one direction or another; the strongest evidence comes from dietary patterns. The current status of the relationship between diet and cardiovascular disease risk calls for more tailored recommendations based on genomic technologies.

    This history of the disease categories "yaws" and "syphilis" explores the interplay between European and African medical cultures in the early modern Atlantic world. The assertion made by both early modern and modern medical authorities, that yaws and syphilis are the same disease, prompts a case study of the history of disease that reflects on a variety of issues in the history of medicine: the use of ideas about contagion to demarcate racial and sexual difference at sites around the British Empire; the contrast between persistently holistic ideas about disease causation in the Black Atlantic and the growth of ontological theories of disease among Europeans and Euro-Americans; and the controversy over the African practice of yaws inoculation, which may once have been an effective treatment but was stamped out by plantation owners who viewed it as a waste of their enslaved laborers' valuable time.
