RESUMEN

Syphilis -the "great simulator" for classical venereologists-is re-emerging in Western countries despite adequate treatment; several contributing factors have been identified, including changes in sexual behaviour, which won't be the topic of this article though. In 2021, a total of 6613 new cases of syphilis were reported in Spain, representing an incidence of 13.9×100 000 inhabitants (90.5%, men). Rates have increased progressively since 2000. The clinical presentation of syphilis is heterogeneous. Although chancroid, syphilitic roseola and syphilitic nails are typical lesions, other forms of the disease can be present such as non-ulcerative primary lesions like Follmann balanitis, chancres in the oral cavity, patchy secondary lingual lesions, or enanthema on the palate and uvula, among many others. Regarding diagnosis, molecular assays such as PCR have been replacing dark-field microscopy in ulcerative lesions while automated treponemal tests (EIA, CLIA) are being used in serological tests, along with classical tests (such as RPR and HAART) for confirmation and follow-up purposes. The interpretation of these tests should be assessed in the epidemiological and clinical context of the patient. HIV serology and STI screening should be requested for anyone with syphilis. Follow-up of patients under treatment is important to ensure healing and detect reinfection. Serological response to treatment should be assessed with the same non-treponemal test (RPR/VDRL); 3-, 6-, 12-, and 24-month follow-up is a common practice in people living with HIV (PLHIV). Sexual contacts should be assessed and treated as appropriate. Screening is advised for pregnant women within the first trimester of pregnancy. Pregnant women with an abortion after week 20 should all be tested for syphilis. The treatment of choice for all forms of syphilis, including pregnant women and PLHIV, is penicillin. Macrolides are ill-advised because of potential resistance.

RESUMEN

BACKGROUND: The global resurgence of syphilis necessitates vaccine development. METHODS: We collected ulcer exudates and blood from 17 primary syphilis (PS) participants and skin biopsies and blood from 51 secondary syphilis (SS) participants in Guangzhou, China for Treponema pallidum subsp. pallidum (TPA) qPCR, whole genome sequencing (WGS), and isolation of TPA in rabbits. RESULTS: TPA DNA was detected in 15 of 17 ulcer exudates and 3 of 17 blood PS specimens. TPA DNA was detected in 50 of 51 SS skin biopsies and 27 of 51 blood specimens. TPA was isolated from 47 rabbits with success rates of 71% (12/17) and 69% (35/51), respectively, from ulcer exudates and SS bloods. We obtained paired genomic sequences from 24 clinical samples and corresponding rabbit isolates. Six SS14- and two Nichols-clade genome pairs contained rare discordances. Forty-one of the 51 unique TPA genomes clustered within SS14 subgroups largely from East Asia, while 10 fell into Nichols C and E subgroups. CONCLUSIONS: Our TPA detection rate was high from PS ulcer exudates and SS skin biopsies and over 50% from SS blood, with TPA isolation in over two-thirds of samples. Our results support the use of WGS from rabbit isolates to inform vaccine development.


The incidence of new cases of syphilis has skyrocketed globally in the twenty-first century. This global resurgence requires new strategies, including vaccine development. As part of an NIH funded Cooperative Research Center to develop a syphilis vaccine, we established a clinical research site in Guangzhou, China to better define the local syphilis epidemic and obtain samples from patients with primary and secondary syphilis for whole genome sequencing (WGS) of circulating Treponema pallidum strains. Inoculation of rabbits enabled us to obtain T. pallidum genomic sequences from spirochetes disseminating in blood, a compartment of immense importance for syphilis pathogenesis. Collectively, our results further clarify the molecular epidemiology of syphilis in southern China, enrich our understanding of the manifestations of early syphilis, and demonstrate that the genomic sequences of spirochetes obtained by rabbit inoculation accurately represent those of the spirochetes infecting the corresponding patients.

RESUMEN

BACKGROUND: Treponema pallidum prevalence and burden at oral and lesion sites in adults with early syphilis were assessed by quantitative polymerase chain reaction (qPCR). Factors associated with oral shedding were also examined. METHODS: Pretreatment oral and lesion swabs were collected from adults with early syphilis in a US multicenter syphilis treatment trial. Oral swabs were collected in the presence and absence of oral lesions. Following DNA extraction, qPCR and whole-genome sequencing (WGS) were performed to assess burden and strain variability. RESULTS: All 32 participants were male, mean age was 35 years, and 90.6% with human immunodeficiency virus (HIV). T. pallidum oral PCR positivity varied by stage: 16.7% primary, 44.4% secondary, and 62.5% in early latent syphilis. Median oral T. pallidum burden was highest in secondary syphilis at 63.2 copies/µL. Lesion PCR positivity was similar in primary (40.0%) and secondary syphilis (38.5%). Age 18-29 years was significantly associated with oral shedding (vs age 40+ years) in adjusted models. WGS identified 2 distinct strains. CONCLUSIONS: T. pallidum DNA was directly detected at oral and lesion sites in a significant proportion of men with early syphilis. Younger age was associated with oral shedding. Ease of oral specimen collection and increased PCR availability suggest opportunities to improve syphilis diagnostic testing. Clinical Trials Registration. NCT03637660.

RESUMEN

Background: Standard therapy for early syphilis involves intramuscular injections of penicillin G, which frequently faces shortages in several countries. Fourteen-day amoxicillin therapy has been suggested as an alternative to benzathine penicillin G, but the optimal duration of amoxicillin therapy remains unclear and could theoretically be shortened to less than 14 days. The aim of this study was to explore the effectiveness of short-term amoxicillin therapy for early syphilis. Methods: We retrospectively explored the effectiveness of short-term amoxicillin therapy for early syphilis. The treatment data of patients who had received amoxicillin therapy for less than 14 days for unintended reasons were reviewed. Diagnosis was confirmed based on either the physician's description or clinical presentation. Successful treatment was defined as a fourfold or greater decline in the rapid plasma reagin titer or sero-reversion to negative within 12 months. Results: Of 295 patients, 8 received short-term amoxicillin treatment. All were men who had sex with men and people living with human immunodeficiency virus. Their median age, CD4 count, and treatment duration were 34 years (range, 26-40), 258/mL (range, 112-930), and 9.5 days (range, 5-11), respectively. One patient had primary syphilis, six had secondary syphilis, and one had early latent syphilis. All patients, except one who showed reinfection, demonstrated a serological response within 4 months. The median time for serological response was 112 days. Conclusion: The results indicate that early syphilis could potentially be treated with 5-11 days of amoxicillin therapy combined with probenecid. This suggests that short-term amoxicillin therapy might be a sufficient treatment for early syphilis instead of the standard 14-day course.

RESUMEN

Background: The widespread occurrence of syphilis remains a global public health problem. Although penicillin has been recommended as the first-line therapy for syphilis for more than 70 years, treatment failure occurs in 10-20% of patients with early syphilis. Recent studies have reported varied single-nucleotide polymorphisms (SNPs) of Treponema pallidum related to penicillin resistance. The clinical relevance of these SNPs to treatment failure in patients with early syphilis is unresolved. In this work, a protocol is developed to evaluate the association between treatment failure in patients with early syphilis and penicillin resistance-related gene mutations of T. pallidum. Methods: A multicentre nested case-control study is designed, and patients who are diagnosed with early syphilis and treated with penicillin will be recruited for the study cohort. Before the first treatment, baseline information and biological specimens will be collected from the subjects, and serological tests for syphilis will be performed. Each participant will be followed up at 1, 3, 6, 9, and 12 months after the first treatment, and the clinical manifestations and serum non-treponemal test titres will be evaluated at each follow-up. Patients who will fail treatment are defined as cases, and those who will respond to treatment are defined as controls. Tests for SNPs related to penicillin-binding proteins and Tp47 will be performed in these cases and controls. Survival analysis is used performed to identify gene mutations of T. pallidum related to penicillin resistance and their combinations associated with treatment failure. Discussion: This protocol provides a practical clinical study design that illustrates the role of gene mutations of T. pallidum related to penicillin resistance in the treatment outcome of patients with early syphilis.

RESUMEN

Background: Starting in 2010, the Chinese government initiated a 10-year syphilis control plan, called the national syphilis control plan (NSCP), to address the emerging threat of syphilis. We aimed to evaluate the effect of the NSCP plan on syphilis control in Jiangsu, China. Methods: The temporal trends of syphilis incidence, prevalence and rate of condom use were estimated by Joinpoint regression with average annual percent change (APC) and average annual percentage (APPC). A Chi-square test was conducted to analyze the outcomes in different subgroups. ArcGIS was used to analyze the spatiotemporal distribution of syphilis incidence. Results: Geographically, early and congenital syphilis incidence decreased significantly in all areas of the province during the period of NSCP. Early syphilis incidence decreased from 21.1 to 8.8 (APC: -7.5, 95%CI: -8.6, -6.5, p < 0.001) per 100,000 people, and congenital syphilis decreased from 63.6 to 4.1 (APC: -14.8, 95%CI: -20.8, -8.4, p < 0.01) per 100,000 newborns from 2010 to 2020. Also, syphilis prevalence reduced from 13.4 to 3.8% (APC: -8.7, 95%CI: -12.1, -5.0, p = 0.001) among men who have sex with men, from 5.3 to 1.7% (APC: -7.9, 95%CI: -11.7, -3.8, p = 0.002) among female sex workers and remained under 1.0% with slight variations among pregnant women (APC: 0.3, 95%CI: -4.3, 5.1, p = 0.877) from 2010 to 2020. 0.2% (2,436) of pregnant women who received free syphilis testing during pregnancy were diagnosed with current syphilis infection, and 97.0% (2,555) of newborns in the province were delivered to women diagnosed with syphilis. 91.8% (2,346) of live babies and about 90% of diagnosed patients received complete standard syphilis diagnosis and treatment services. Conclusion: Trends of early syphilis incidence and syphilis prevalence show a considerable decreasing trend among almost all the key populations after implementing NSCP. Congenital syphilis has significantly decreased as well and hence, the NSCP program should be sustained and strengthened to control the syphilis epidemic in China further.

RESUMEN

A 66-year-old unemployed unmarried male with known men sex men activity since the age of 20 years presented with an erythematous well-defined ulcer on the lower lip and multiple discrete papulo-squamous lesions on the palms, soles, and scrotum. The patient was also in dysphoric mood with grandiose ideas with normal higher function. Knee and ankle jerk reflexes were absent and there was impaired tandem walking. Venereal Disease Research Laboratory (VDRL) and treponema pallidum hemagglutination assay were positive. Cerebrospinal fluid-VDRL was positive with grossly elevated proteins and glucose. HIV test was negative. Magnetic resonance imaging scan of the brain was normal. We made a diagnosis of neurosphilis - General paralysis of insane (GPI) with co-existing early syphilis. The patient was started on crystalline penicillin for 14 days after which there was significant improvement in behavior. We are reporting a rare case of GPI with early syphilis.

RESUMEN

Syphilitic osteitis is one of the rare and often under-reported complications of early syphilis. Recognizing this entity is important as it may mimic other conditions like multiple myeloma, lymphoma, or metastatic malignancies. Misdiagnosis and delayed management can lead to irreversible destructive lesions. We herein report a case of calvaria syphilitic osteitis that was initially investigated for possible lymphoma and later diagnosed as secondary syphilis.

RESUMEN

Safe and efficacious alternative treatment options for syphilis are necessary. This randomized, 2-arm, noncomparative pilot study evaluated the efficacy of oral cefixime 400 mg in achieving a ≥4-fold rapid plasma reagin titer decrease by 3 or 6 months after treatment. The proportion of cefixime arm participants treated successfully was 87% (95% confidence interval, 69%-100%; 13/15). Clinical Trials Registration. NCT03752112.

RESUMEN

BACKGROUND: Neurosyphilis, a complication of syphilis, can occur at any stage of infection. Measuring the prevalence of neurosyphilis is challenging, and there are limited data on the prevalence of neurologic or ocular symptoms among patients with syphilis. We sought to describe the prevalence of neurologic and/or ocular symptoms among early syphilis (ES) cases and the clinical management of symptomatic cases enrolled in the STD Surveillance Network (SSuN) Neuro/Ocular Syphilis Surveillance project. METHODS: Persons diagnosed with ES were selected for interviews based on current health department protocols in 5 participating SSuN jurisdictions from November 2016 through October 2017. All interviewed ES cases were screened for self-reported neurologic and/or ocular symptoms. Additional clinical information on diagnostic testing and treatment for cases concerning for neurosyphilis/ocular syphilis was obtained from providers. RESULTS: Among 9123 patients with ES who were interviewed, 151 (1.7%; 95% confidence interval [CI], 1.4%-1.9%) reported ≥ 1 neurologic or ocular symptom. Of the 53 (35%) who underwent lumbar puncture, 22 (42%) had documented abnormal cerebrospinal fluid, of which 21 (95%) were treated for neurosyphilis/ocular syphilis. Among the remaining 98 symptomatic patients with no documented lumbar puncture (65%), 12 (12%) were treated for and/or clinically diagnosed with neurosyphilis/ocular syphilis. CONCLUSIONS: We observed a low prevalence of self-reported neurologic and/or ocular symptoms in interviewed ES cases. Approximately one-third of ES cases who self-reported symptoms underwent further recommended diagnostic evaluation. Understanding barriers to appropriate clinical evaluation is important to ensuring appropriate management of patients with possible neurologic and/or ocular manifestations of syphilis.

RESUMEN

BACKGROUND: Syphilis rates have been increasing both in the USA and internationally with incidence higher among men-who-have-sex-with-men and people living with human immunodeficiency virus (HIV) infection. Currently, benzathine penicillin is the recommended treatment for syphilis in all patients. Global shortages and cost increases in benzathine penicillin call for alternative treatment options. This study evaluates the efficacy of oral cefixime for the treatment of early syphilis. METHODS: We are conducting a randomized, multisite, open-label, non-comparative clinical trial in Los Angeles and Oakland, CA. Eligible participants are ≥ 18 years old, with primary, secondary, or early latent syphilis (rapid plasma reagin [RPR] titer ≥ 1:8). Patients with HIV infection must have a viral load ≤ 200 copies/mL and CD4+ T cell count ≥ 350 cells/µL during the past 6 months. Participants are randomized to receive either 2.4 M IU benzathine penicillin G intramuscularly once or cefixime 400 mg orally twice a day for 10 days. Participants return at 3, 6, and 12 months post-treatment for follow-up RPR serological testing. The primary outcome is the proportion of participants who achieve ≥ 4-fold RPR titer decrease at 3 or 6 months post-treatment. DISCUSSION: Clinical trials evaluating the efficacy of alternative antibiotics to penicillin are urgently needed. TRIAL REGISTRATION: Clinicaltrials.gov NCT03660488 . Registered on 4 September 2018.

RESUMEN

BACKGROUND: Since 2000, substantial increases in syphilis have been reported in metropolitan areas of Western countries, with increases noted among men who have sex with men (MSM). Clinical manifestations of syphilis might be influenced by concomitant VIH infection and previous episodes of syphilis. The objectives of this study were to describe the epidemiological and clinical characteristics of the cases of syphilis diagnosed in Barcelona. METHODS: Retrospective study of cases with early syphilis diagnosed in the referral STI Unit of Barcelona from January 2003 to December 2013. Revision of medical records with structured collection of epidemiological and clinical data. Univariate and multivariate statistical analyses comparing the characteristics of MSM cases with and without VIH infection and with and without previous syphilis. RESULTS: A total of 1702 cases of syphilis (37% primary, 48% secondary and 14% early latent) were diagnosed, 93% of them in MSM. Among MSM 40% were coinfected with VIH, VIH-positive cases were associated with a previous syphilis (aOR, 5.2 [95% CI, 3.32-8.24]) and with unprotected anal intercourse (aOR, 1.75 [95%CI, 1.17-2.63]). Cases with a history of syphilis presented less often with primary syphilis compared to those without it (27.5% vs. 40%) (aOR, 0.58 [95% CI, 0.44-0.77]). One year after treatment, the clinical and serological evolution were similar between VIH-positive and VIH-negative cases. CONCLUSION: The epidemic of syphilis in Barcelona disproportionately affects MSM and is closelly linked to VIH infection. The presentation of syphilis is influenced by VIH infection and by previous history of syphilis, without significant differences in their evolution after one year of treatment.

RESUMEN

BACKGROUND: Some patients with early syphilis who receive appropriate treatment do not reach a serological cure and have a persistent titer which does not meet the criteria for treatment failure (serofast state). AIMS: This retrospective study aimed to determine the prevalence of serological cure and the serofast state as well as the factors associated with serological cure after treatment of patients with early syphilis. METHODS: A serological cure was defined as occurring when there was a ≥4-fold decrease in nontreponemal titer, whereas patients with a ≥4-fold increase were considered as having either a treatment failure or reinfection. Nontreponemal titers that neither increased nor decreased ≥4-fold after treatment were considered to be in a serofast state. Seroreversion was defined as occurring when there was a negative test within 12 months of treatment. RESULTS: There were 179 patients with a mean age of 31.9 years; 174 (97.2%) were men, and 125 (70%) were HIV patients. Of the total, 174 (98%; 95% confidence interval 94.82-99.42%) patients achieved a serological cure, whereas five were in a serofast state 12 months after treatment. Those five serofast patients were all HIV-positive men, of which 4 (80%) had secondary-stage syphilis, a CD4 count ≤200 cells/µl and a titer <1:8. In a bivariate analysis, a serological cure was associated with a baseline Venereal Disease Research Laboratory >1:16 titers (P = 0.018), and a CD4 cell count >200 cells/µl in 6 months preceding treatment (P = 0.016). The median time to a serological cure was 96 days. Only 22 (12.3%) of the patients achieved seroreversion at 12 months after treatment. LIMITATIONS: A retrospective medical record review is likely to have a selection bias, and in our study, 196 (52%) patients were excluded due to missing information. CONCLUSIONS: Most patients with early syphilis who achieved a serological cure at 12 months after treatment had high baseline Venereal Disease Research Laboratory titers and CD4 cell counts. However, only 22 (12.3%) had a negative Venereal Disease Research Laboratory titer after 1 year of treatment.

RESUMEN

BACKGROUND: Few studies have investigated predictors of serological response to syphilis treatment in people living with HIV (PLWH). METHODS: This was a retrospective, longitudinal study on PLWH who were diagnosed with and treated for syphilis who had an assessable serological response between January 2004 and June 2016. Serological treatment response (TR) was defined as a ≥4-fold decline in rapid plasma reagin (RPR) titers or a reversion to nonreactive (if RPR ≤1:4 at diagnosis) 12 months after treatment for early syphilis and 24 months after treatment for late syphilis. Factors associated with a TR were assessed with multivariate Cox proportional hazard models for recurrent events. RESULTS: A total of 829 episodes of syphilis (686 early, 143 late) in 564 patients were recorded. TR was observed in 732 (88%) syphilis episodes. The proportion of TR differed between early and late syphilis (89% vs 83%, respectively; P = .045). For early syphilis, TR was associated with a higher nadir CD4+ cell count (adjusted hazard ratio [AHR], 1.06; P = .029), an RPR titer >1:32 at diagnosis (AHR, 1.26; P = .009), secondary syphilis (AHR, 1.29; P = .008), and cases of syphilis diagnosed in more recent calendar years (AHR, 1.36; P < .0001). In late syphilis, TR was more likely to occur for first infections (AHR, 1.80; P = .027), for episodes that occurred in more recent years (AHR, 1.62; P = .007), and for RPR titers >1:32 at diagnosis (AHR, 2.04; P = .002). TR was not associated with the type of treatment regimen in early and late syphilis. CONCLUSIONS: Higher RPR titers at diagnosis and a diagnosis of syphilis that was made in more recent years were associated with TR in early and late syphilis.

RESUMEN

INTRODUCTION: The evolution of syphilis after treatment could be affected by different factors, for example HIV. In consequence, HIV positive patients are sometimes treated with more doses of penicillin (PBG). The aim of the study is to describe and compare the serological evolution by different factors in patients with early syphilis in Barcelona. METHODS: The serological control was made over the following year. A time analysis was performed through the study of Kaplan- Meier curves. RESULTS: The serological control was made in 208 patients, 42.5% of whom were HIV-positive. In a Kaplan-Meier curve the median of days needed to observe the cure was 99 [97-105] without differences depending on HIV, previous syphilis, stage or RPR titters. A better evolution was observed in patients treated with doxycycline P=.02. CONCLUSIONS: The serological evolution is similar in HIV-negative and HIV-positive patients treated according to current recommendations, observing the cure at 3 month after treatment.

RESUMEN

@#The objective of this study was to examine the trends of primary and secondary syphilis in Tokyo between 2007 and 2016 using national infectious disease surveillance data. We analysed all 3269 cases reported during these 10 years. A statistically significant increase in cases was observed after 2010 with a more rapid rate of increase after 2014 mainly in urban areas in Tokyo. The notification rates per 100 000 population in 2010, 2014 and 2016 were 0.9 (n = 113), 2.2 (n = 295) and 8.7 (n = 1190), respectively. Domestic syphilis transmission was suspected in 92.6–99.3% of cases during the period 2007–2016. Until 2013, the increase was mainly observed among men who have sex with men (MSM); however, heterosexual transmission became more dominant and eventually surpassed transmission among MSM in 2015. In 2016, the notified cases of infections through heterosexual contact were 22.3 and 40.4 times higher in men and women, respectively, compared to those in 2010. The median ages of affected heterosexual men and women were 37 (interquartile range: 28–46) and 26 (interquartile range: 22–32) years, respectively. Reports of oropharyngeal lesions have been increasing among both men and women with syphilis. The number of congenital syphilis cases reported in Tokyo was 0 to 3 cases per year during the study period. More information and further analysis are needed to explain the reason for this increase.

RESUMEN

BACKGROUND: The aim of this study was to assess the efficacy of ceftriaxone and benzathine penicillin G (BPG) in nonpregnant, immunocompetent adults with early syphilis because there is a lack of clinical evidence supporting ceftriaxone as an alternative treatment for early syphilis without an human immunodeficiency virus coinfection. METHODS: A randomized, open-label controlled study evaluating the efficacy of ceftriaxone and BPG was conducted in 4 hospitals in Jiangsu Province. Treatment comprised either ceftriaxone (1.0 g, given intravenously, once daily for 10 days) or BPG (2.4 million units, given intramuscularly, once weekly for 2 weeks). A serological response was defined as a ≥4-fold decline in the rapid plasma reagin (RPR) titer. RESULTS: In all, 301 patients with early syphilis were enrolled in this study; 230 subjects completed the follow-ups. The serological response at 6 months of follow up was observed in 90.2% in ceftriaxone group and 78.0% in BPG group (P = .01). There was no significant difference between treatment groups in patients with primary or early latent syphilis, but among patients with secondary syphilis the difference was highly significant (95.8% vs 76.2%; P < .01). Moreover, patients exhibiting a Jarisch-Herxheimer reaction after treatment might have a shorter period before a serological response (P = .03). CONCLUSIONS: In this study, ceftriaxone regimen was noninferior to the BPG regimen in nonpregnant, immunocompetent patients with early syphilis. CLINICAL TRIALS REGISTRATION: ChiCTR-TQR-13003624.

RESUMEN

Objective To investigate the clinical efficacy of penicillin combined with ceftriaxone in early syphilis patients.Methods60 patients with early syphilis treated from February 2014 to February 2016 were included in the study,according to the random number table method,the patients were divided into control group (simple penicillin treatment) and treatment group (Penicillin and ceftriaxone sodium), 30 cases in each group.The skin lesions subsided within one week of two groups were recorded.The toluidine red blood serum test (TRUST) was carried out at 3 months, 6 months, 9 months and 12 months after treatment, and the serum fixation rate of the patients in the two groups were observed.ResultsThe rate of pain relief within one week in the treatment group was 90.0% (27/30), which was significantly higher than that in the control group (66.7%, 20/30), (χ2=4.81, P=0.02);TRUST negative rates of the treatment group after treatment for 3 months, 6 months, 9 months and 12 months were 36.7%(11/30), 70.0% (21/30), 86.7% (26/30), 90.0% (27/30),the control group was 13.3%(4/30), 26.7% (8/30), 50.0% (15/30), 63.3% (19/30), [χ2=(4.35,11.27,9.31,5.96), P=(0.00,0.00,0.00, 0.01)].The serum fixation rate in the treatment group was 3.3%(1/30), which was significantly lower than that in the control group (20.0%, 6/30),(χ2=4.04, P=0.04).ConclusionPenicillin combined with ceftriaxone sodium in the treatment of early syphilis patients can help to promote the disappearance of skin lesions, accelerate the patients with syphilis serum negative and reduce serum fixation rate, the effect is significant, to be further studied to promote.
