Foi observado uma incidência maior para sífilis adquirida entre homens em comparação com mulheres tanto no estado do Rio de Janeiro (62.719 versus 42.346) quanto no município de Seropédica (110 versus 77). Houve um aumento nas taxas de incidência de sífilis no estado do Rio de Janeiro e no município de Seropédica ao longo dos anos. Conclusão: a sífilis segue sendo uma doença com alta incidência no território do Rio de Janeiro. Nesse sentido, é importante elaborar estratégias em saúde pública mais efetivas às pessoas acometidas por tal infecção.

Syphilis is a sexually transmitted infection (STI) that signals the need for effective public policies due to the increase in cases in the last decade. Thus, the aim of this study is to describe the incidence of syphilis in the state of Rio de Janeiro and in the municipality of Seropédica. Methods: a descriptive study with a quantitative approach was carried out. Data collection was performed through the Sistema de Informação de Agravos de Notificação (Sinan), referring to the municipality of Seropédica and the state of Rio de Janeiro, from 2010 to 2022. Results: overall, 105.138, 79.609 and 42.819 cases of acquired syphilis, in pregnant women, and congenital syphilis, respectively, were identified in the state of Rio de Janeiro, and 187, 140, and 79 cases of acquired syphilis, in pregnant women, and congenital syphilis, respectively, were identified in the municipality of Seropédica. A higher incidence of acquired syphilis was observed among men compared to women both in the state of Rio de Janeiro (62.719 versus 42.346) and in the municipality of Seropédica (110 versus 77). There has been an increase in the incidence rates of syphilis in the state of Rio de Janeiro and the municipality of Seropédica over the years. Conclusion: syphilis continues to be a disease with a high incidence in the territory of Rio de Janeiro. In this sense, it is important to develop more effective public health strategies for people affected by this infection.

Successful open repair of syphilitic thoracoabdominal aneurysm.

Most syphilitic aneurysms involve the ascending aorta. Those involving the descending aorta are less common, and those involving the abdominal aorta are unusual. Rarer yet, we present the case of a 40-year-old man with HIV and a history of syphilis with a thoracoabdominal aneurysm. The patient underwent antiretroviral therapy before elective open repair. His postoperative course was uneventful, and he was discharged home. Pathology demonstrated medial necrosis. Postoperatively, he was seen well in our multidisciplinary aorta center clinic. Today's vascular surgeons should be cognizant of cardiovascular syphilis. Successful care requires awareness of atypical presentations in addition to multispecialty care.

Syphilis Clinical Complexity: A Dual-Case Study Illustrating Diagnostic Dilemmas and Management Strategies.

Syphilis, a bacterial sexually transmitted infection, poses diagnostic challenges due to its diverse clinical manifestations. This report presents two distinctive cases illustrating the diagnostic dilemmas and management strategies associated with syphilis. The first case describes a male in his early 30s presenting with secondary syphilis and condyloma lata, illustrating the atypical genital lesions that can arise. The second case involves a male in his late 40s with late latent syphilis exhibiting unusual cutaneous manifestations, underscoring the diagnostic complexities of the disease. These cases underscore the importance of healthcare providers remaining vigilant in identifying unusual presentations of syphilis to ensure timely intervention and prevent transmission and complications.

Molluscum contagiosum is associated with atopic dermatitis and sexually transmitted infections in a matched case-control study using a national database.

BACKGROUND: Molluscum contagiosum (MC) is a poxvirus that manifests as firm, smooth, dome-shaped, umbilicated, flesh-colored papules. In adults, MC is commonly spread by sexual contact, and is self-limited in patients with intact immune systems but more widely distributed and difficult to treat in immunocompromised persons. We analyzed cases of adult MC for associations with immunosuppression, lifestyle risk factors, and sexually transmitted infections (STIs). METHODS: Using the All of Us Research Program database, adults with MC were identified and matched with controls 1:10 based on demographic factors. Comorbidities, lifestyle risk factors, and medication exposures were analyzed. Odds ratios were calculated using logistic regression. RESULTS: Our analysis included 146 cases of adults with MC and 1460 demographic-matched controls. Patients with MC were 48 years old on average, 59% female, and majority White (82.5%). Controls were similar for all demographic features. Adults with MC were more likely to have syphilis (odds ratio (OR) 16; 95% confidence interval (CI) 2.57-99.5), human immunodeficiency virus (HIV) (OR 9.54; 95% CI 3.95-23.0), chlamydia (OR 6.24; 95% CI 2.38-16.4), condyloma acuminata (OR 13.9; 95% CI 7.36-26.2), genital herpes (OR 4.13; 95% CI 1.87-9.15), or atopic dermatitis (AD) (OR 2.85; 95% CI 1.5-5.4) (all p < .01). There were no differences in prevalence of other comorbidities, lifestyle risk factors, nor medication exposures (all p > .05). CONCLUSIONS: We showed that adult MC is associated with AD and STIs, including HIV, chlamydia, condyloma acuminata, genital herpes, and syphilis. Sexually active adolescents and adults and those diagnosed with AD may be screened for MC and counseled on their potentially increased risk.

Feasibility and Acceptability of a Motivational Interviewing-Based Telehealth Intervention for Bacterial Sexually Transmitted Infection Screening: Protocol for a Sequential Explanatory Mixed Methods Study.

BACKGROUND: Gay, bisexual, and other men who have sex with men living with HIV (GBMSM-LWH) in the United States bear a heavy burden of bacterial sexually transmitted infections (STIs). Timely diagnosis and treatment are key to prevention. Only a few studies have combined home specimen self-collection for bacterial STI screening with live audio and video (AV) conferencing. None have focused on GBMSM-LWH or incorporated motivational interviewing (MI), a client-centered, strengths-based counseling approach that seeks to support individuals to create positive behavioral change. OBJECTIVE: Our study seeks to investigate the feasibility and acceptability of an MI-based telehealth intervention that integrates home specimen self-collection from different anatomical sites of possible exposure and MI delivered via live AV conferencing to engage sexually active GBMSM-LWH in bacterial STI screening. METHODS: Participants are being recruited from across the United States via advertising on mobile dating apps and social networking sites and via peer referral. Phase 1 involves piloting the delivery of an innovative telehealth intervention for bacterial STI screening to 75 GBMSM-LWH. Our intervention includes three components: (1) a pretest live AV conferencing session involving an MI-guided discussion to elicit awareness of bacterial STIs; fill any knowledge gaps; bolster the perceived importance of regularly testing for gonorrhea, chlamydia, and syphilis; and build self-efficacy for specimen self-collection; (2) home self-collection and return via mail of a urine sample (for gonorrhea and chlamydia testing), a throat swab (for gonorrhea and chlamydia testing), a rectal swab (for gonorrhea and chlamydia testing), and a finger-stick blood sample (for syphilis testing); and (3) a posttest live AV conferencing session involving an MI-guided discussion to prepare participants for receiving test results and formulate personalized action plans for seeking treatment (if warranted) and repeat testing. Descriptive statistics and progression ratios will be calculated, and potential variations in our intervention's feasibility and acceptability will be numerically summarized and graphically visualized. Phase 2 involves elucidating attitudes, facilitators, and barriers related to engaging in each intervention component via semistructured in-depth interviews with a purposive subsample of 20 participants who complete progressively smaller subsets of the pretest session, specimen return for bacterial STI testing, and the posttest session. Thematic analysis will be used to identify, analyze, and report patterns in the data. Quantitative and qualitative data will be integrated at the design, methods, interpretation, and reporting levels. RESULTS: Study procedures were approved by the Institutional Review Board at the University of Michigan in September 2023. Participant recruitment began in April 2024. CONCLUSIONS: Our study will advance multiple goals of the STI National Strategic Plan for the United States for 2021 to 2025, specifically those pertaining to preventing new STIs; accelerating progress in STI research, technology, and innovation; and reducing STI-related health disparities.

Primary Rectal Syphilis Mimicking Lymphoma: A Case Report and Literature Review.

Primary rectal syphilis is a rare disease that can be misdiagnosed as lymphoma or other rectal cancers on sigmoidoscopy or CT. Here, we report a case of primary rectal syphilis mimicking rectal malignancy in a 23-year-old male who presented with a rectal mass and multiple lymphadenopathies. In this case report and literature review, we focused on the CT findings and endoscopic observations of primary rectal syphilis. Infectious diseases, such as rectal syphilis, should be considered in the differential diagnosis of young patients with unusual rectal lesions and disproportionately extensive lymphadenopathies.

Actinic Granuloma Complicated by Secondary Syphilis: A Case Report.

Introduction: Actinic granuloma (AG) is a rare skin eruption thought to result from a sun-induced inflammatory response attracting giant cells, which are large, multinucleated, and inflammatory, to form granulomas and degrade surrounding elastic material. Clinically, lesions begin on sun-exposed skin as pink papules and nodules that coalesce into demarcated annular plaques with a hypopigmented center. Histologically, actinic elastosis surrounds the outer annulus ring, with histiocytes and giant cells within the raised border, and the innermost central zone is filled with minimal to absent elastic fibers. Case Presentation: We present a middle-aged female with a pruritic eruption of diffuse erythematous macules and papules coalescing into plaques with mild scale involving the scalp, face, neck, torso, and upper and lower extremities, including the palms and soles, but sparing the ears, bilateral axillae, elbows, and knees. Skin biopsies revealed solar elastosis and abundant multinucleated foreign body giant cells with ingested elastic fibers. The patient's clinical presentation and histopathology were consistent with a diagnosis of AG. Furthermore, spirochete immunostaining of the specimens revealed multiple Treponema pallidum spirochetes throughout the epidermis and dermis. Secondary syphilis with primary chancre was added to the diagnosis. Treatment included oral and topical steroids followed by intravenous penicillin G. After 1 month, all lesions had resolved with post-inflammatory erythema. Conclusion: Our patient differs from the typical presentation in describing intense pruritus with her eruption. This interesting collision reminds clinicians to retain a high index of suspicion for multiple diagnoses in a single patient.

Novel and characteristic radiological features of neurosyphilis: a case series.

BACKGROUND: Treponema pallidum can invade the central nervous system (CNS) early in its infection, causing neurosyphilis. Neurosyphilis typically presents with meningovasculitis in the acute or subacute phase, while tabes dorsalis and dementia paralytica are classical conditions in the later stages. However, syphilis is often misdiagnosed as other conditions such as tumors or autoimmune diseases including vasculitis and encephalitis, which is why the condition is known as "The Great Mimicker." The increasing incidence of syphilis in recent years emphasizes the importance of early diagnosis and treatment; however, its multiple clinical manifestations impose diagnostic challenges for clinicians because it resembles other diseases. In this case series, we present the impressive manifestations of neurosyphilis through three unique radiological presentations. CASE PRESENTATION: Case 1 details optic nerve involvement in an HIV-positive male, where MRI and fundoscopic findings confirmed syphilitic optic neuritis. Case 2 describes a patient in her pregnancy initially suspected of acoustic neuroma on MRI, later diagnosed with syphilitic gumma affecting the inner ear canal. Case 3 is a young male with clinical features mimicking temporal arteritis, ultimately identified as skull osteomyelitis secondarily causing inflammation of the musculus temporalis and meningitis. CONCLUSIONS: These cases underscore the necessity of considering syphilis in differential diagnoses, given the diversity of its clinical presentations. Radiology plays an important role in avoiding unnecessary interventions. The increasing prevalence of recurrent syphilis imposes diagnostic challenges, emphasizing the importance of the early diagnosis and treatment of neurosyphilis by clinicians.

Sexually transmitted infections among active component members of the U.S. Armed Forces, 2015-2023.

This report summarizes incidence rates and trends of sexually transmitted infections (STIs) from 2015 through 2023 among active component service members of the U.S. Armed Forces. The data compiled for this report are derived from the medical surveillance of chlamydia, gonorrhea, and syphilis as nationally notifiable diseases. Case data for 2 additional STIs, human papilloma virus (HPV) and genital herpes simplex virus (HSV), are also presented. The crude total case rates of chlamydia and gonorrhea initially rose by an average of 6.7% and 9.8% per year, respectively, until 2019. From 2020 onwards, rates steadily declined. By 2023, chlamydia rates had dropped by approximately 39%, while gonorrhea rates had fallen by more than 40% for female, and 19% for male, service members. Initially syphilis increased, on average, 10% annually from 2015 to 2019, then declined in 2020, but resumed its upward trend through 2023, nearly doubling the 2015 rate in 2023. The total crude annual incidence rates of genital HPV and HSV exhibited downward trends in general over the surveillance period, decreasing by 30.7% and 24.7%, respectively. Age- and gender-adjusted case rates for chlamydia, gonorrhea, and syphilis remain elevated within the U.S. Armed Forces compared to the general U.S. population, which may be due to factors that include mandatory STI screening, more complete reporting, incomplete adjustment for age distribution, and inequitable comparisons between the military active duty and general U.S. populations. Social restrictions enacted during the COVID-19 pandemic may have contributed to declines in true case rates and screening coverage.

Severe Cutaneous Manifestation of Malignant Syphilis in a Patient with Behçet's Uveitis: A Case Report.

Introduction: Syphilis exhibits a wide range of clinical presentations, mimicking various systemic and ocular diseases. Ocular syphilis, in particular, manifests with multiple presentations, ranging from anterior uveitis to panuveitis, making it a potential differential diagnosis for Behçet's uveitis. Here, we present a unique case of Behçet's panuveitis that was undergoing immunomodulatory therapy and was complicated by ocular syphilis. Notably, this case also featured rare cutaneous manifestations associated with secondary syphilis, commonly known as malignant syphilis. Case Presentation: A 38-year-old Thai man with refractory end-stage Behçet's panuveitis reported a maculopapular rash accompanied by increased intraocular inflammation. The escalation of immunomodulatory therapy, intended to manage the provisional diagnosis of active ocular and cutaneous Behçet's disease, resulted in clinical deterioration, with the rash transforming into multiple noduloulcerative lesions. Despite negative serologic tests for syphilis at baseline before initiating immunomodulatory therapy, syphilis infection was eventually diagnosed following reevaluation and the observation of spirochetes in a skin biopsy specimen. The patient was treated with intravenous penicillin G, resulting in an improvement in intraocular inflammation and resolution of noduloulcerative rashes. Conclusion: Intraocular inflammation and mucocutaneous lesions in syphilis can mimic the presentation of Behçet's disease. The introduction of immunomodulatory therapy may alter the clinical picture, leading to a severe and atypical presentation. A high index of suspicion for reevaluating serologic tests or performing tissue biopsies is warranted for an accurate diagnosis.

Improved efficiency using sequential automated immunoassays for syphilis screening in blood donors.

Using sequential immunoassays for the screening of blood donors is well described for viral serology testing but not for the screening of syphilis. In this study, we report the evaluation results and 2-year sequential testing data using two highly sensitive automated serology assays, the Alinity s Syphilis chemiluminescent immunoassay for screening, with all repeatedly reactive samples then tested on the Elecsys Syphilis electrochemiluminescence immunoassay. We screened 1,767,782 blood donor samples between 7 July 2021 and 6 July 2023 and found the Alinity false-positive rate to be low at 0.08% (1,456/1,767,782). The common false-positive rate between the two assays was also low (3.83%, 58/1,514). Concordantly reactive samples were further tested using a Treponema pallidum particle agglutination test, a rapid plasma reagin test, and a fluorescent treponemal antibody absorption test. There were 262/1,376 concordantly reactive Alinity and Elecsys blood donor samples with reactivity on one or more of the confirmatory tests. A total of 26/1,376 donors had a current syphilis infection, 152/1,376 reported a past history of syphilis and had been treated, and 84/1,376 did not report a past history of syphilis. We suggest that future studies could explore the use of sequential immunoassays to aid in the serodiagnosis for syphilis. IMPORTANCE: The serodiagnosis for syphilis usually follows two methodologies-a "traditional" algorithm using a non-treponemal test followed by confirmation using a treponemal test, or a "reverse" algorithm using a treponemal test followed by a non-treponemal test. There are limited reports in the literature of using a modified reverse algorithm (treponemal test followed by a second treponemal test), and to the best of knowledge, there are currently no published articles using two highly sensitive automated immunoassays to aid the serodiagnosis of syphilis. In addition, the Treponema pallidum particle agglutination (TPPA) assay is commonly used as a confirmatory test for the diagnosis of syphilis. With the withdrawal of the TPPA assay from Australia and presumably from the global market also, alternative testing algorithms are now required. This study provides proof of concept for using sequential immunoassays in the diagnosis of syphilis.

Ulcerative erythematous papules and plaques on the face and lower legs of a man living with HIV: a clinicopathological challenge.

A 44-year-old male presented with a 2-month history of erythematous ulcerative papules and plaques on the scalp, face, and bilateral lower legs. He had a 5-year history of well-controlled HIV on antiretroviral therapy and recurrent syphilis infections. His face had violaceous plaques, while bilateral ankles and calves had ulcerative lesions with necrotic centers and purple borders. The morphologies clinically mimicked pyoderma gangrenosum on the lower extremities and cutaneous lymphoma on the face. Biopsy and reactive rapid plasma reagin confirmed a diagnosis of lues maligna, and the patient was successfully treated with penicillin G benzathine.

A Case of Perianal Annular Rash: Atypical Presentation of Recurrent Secondary Syphilis.

Syphilis is a complex, systemic infectious disease caused by Treponema pallidum subspecies pallidum. Secondary syphilitic lesions typically manifest within 3 months following initial exposure to T. pallidum. The predominant cutaneous manifestations of secondary syphilis are macula and papule. Certain individuals with syphilis may present with an atypical rash during the secondary stage owing to immunosuppression and other factors. Herein, we report a rare case of atypical recurrent secondary syphilis around the anus in a 65-year-old woman. Based on cerebrospinal fluid findings and skin biopsy results, the patient was ultimately diagnosed as neurosyphilis and recurrent secondary syphilis. Following intravenous antibiotic therapy, the patient's rash improved significantly. This case underscores the importance for physicians to remain vigilant regarding the possibility of syphilis when encountering cases exhibiting unusual clinical manifestations, as a definitive diagnosis necessitates a comprehensive evaluation.

Clinic-based evaluation of point-of-care dual HIV/syphilis rapid diagnostic tests at primary healthcare antenatal facilities in South Africa and Zambia.

BACKGROUND: Southern African countries have the largest global burden of HIV and syphilis, with a high prevalence among women of reproductive age. Although antenatal screening is standard of care, syphilis screening has generally lagged behind HIV screening. We aimed to evaluate the performance and operational characteristics of two commercial dual HIV/syphilis point-of-care tests (POCTs) for simultaneous maternal HIV/syphilis screening. METHODS: A clinic-based evaluation of dual HIV/syphilis POCTs (SD Bioline and Chembio) was conducted at five primary healthcare centres (PHCs) in South Africa and Zambia. POCT results using capillary fingerprick blood were compared to reference laboratory syphilis and HIV serological assays. RESULTS: Three thousand four hundred twelve consenting pregnant women aged ≥ 18 years were enrolled. The prevalence of treponemal antibody seropositivity and HIV infection ranged from 3.7 to 9.9% (n = 253) and 17.8 to 21.3% (n = 643), respectively. Pooled sensitivity for syphilis compared to the reference assay was 66.0% (95%CI 57.7-73.4) with SD Bioline and 67.9% (95%CI 58.2-76.3) with Chembio. Pooled specificity for syphilis was above 98% with both POCTs. The sensitivities of SD Bioline and Chembio assays were 78.0% (95%CI 68.6-85.7) and 81.0% (95%CI 71.9-88.2), respectively compared to an active syphilis case definition of treponemal test positive with a rapid plasma reagin titre of ≥ 8. The negative predictive values (NPVs) based on various prevalence estimates for syphilis with both assays ranged from 97 to 99%. The pooled sensitivity for HIV was 92.1% (95%CI 89.4-94.2) with SD Bioline; and 91.5% (95%CI 88.2-93.9) with Chembio. The pooled specificities for HIV were 97.2% (95%CI 94.8-98.5) with SD Bioline and 96.7% (95%CI 95.1-97.8) with Chembio. The NPV based on various prevalence estimates for HIV with both assays was approximately 98%. Most participating women (91%) preferred dual POCTs over two single POCTs for HIV and syphilis, and healthcare providers gave favourable feedback on the utility of both assays at PHC level. CONCLUSIONS: Based on the need to improve antenatal screening coverage for syphilis, dual HIV/syphilis POCTs could be effectively incorporated into antenatal testing algorithms to enhance efforts towards elimination of mother-to-child transmission of these infections.

Is syphilis infection a risk factor for cervicovaginal HPV occurrence? A case-control study.

BACKGROUND: Syphilis and human papillomavirus (HPV) are sexually transmitted infections affecting women in the same risk group. Thus, the main objective of the present study was to investigate the prevalence of HPV in a population of women with and without syphilis and observe the characteristics of HPV cervical lesions when coinfection occurs. Sociodemographic factors associated with coinfection were also evaluated. METHODS: This case-control study was conducted at a Brazilian HIV/STD testing and training center. Study groups were composed of women with (case) and without syphilis (control), paired by age. The presence of HPV, HPV subtype, and lesion severity were investigated. All women were subjected to a sociodemographic interview, clinical data collection, cell collection for cytopathological analysis, and a hybrid capture test for HPV diagnosis. The chi-square test was used for statistical analysis. RESULTS: The sample consisted of 176 women, 88 in each group. The prevalence of HPV was 14.8 % in the case (n = 13) and 18.1 % in the control group (n = 16), and there was no statistically significant difference between them. Illiterate individuals were more prevalent in the control group (p = 0.023). Considering women with suggestive signs of STIs, 30 % (6) of the patients and controls had high-risk HPV, and 15 % (3) had coinfection. The cytopathological assessment showed no differences between the groups concerning cellular atypia. However, ASC-US and ASC-H (atypical squamous cells of undetermined significance and high-grade) were only found in women with coinfections, with 75 % of these patients testing positive for high-risk HPV. Considering the distribution of lesions on the cervix, the HSIL (high-grade intraepithelial lesion) was assessed in high-risk HPV patients, both cases and controls. CONCLUSIONS: The prevalence of HPV was not increased in patients infected with syphilis. In addition, coinfection does not seem to be an aggravating factor for the presence of precursor lesions of cervical cancer.

Condyloma lata of the umbilicus: A case report highlighting the present syphilis emergency.

Syphilis is an ancient sexually transmitted infection that plagues communities across the United States and the world. Cutaneous syphilis has a wide variety of manifestations and presentations, and is notoriously difficult to identify clinically as a result. In this report, we describe the case of a 30-year-old patient with condyloma lata on the umbilicus, an extremely rare site for the presentation of these lesions. With the recent surge in syphilis infections nationwide, including congenital infections, this case underscores the urgent necessity for heightened syphilis awareness and suspicion among clinicians.

Ocular Syphilis as a Primary Manifestation of Neurosyphilis: A Case Report.

Sexually transmitted infectious diseases could affect a variety of organs, generating significant symptomatology. In the elderly population, infectious causes for vision problems are not generally considered. We present the case of an elderly patient with blurred vision and darkening of visual fields. He underwent an unsuccessful biopsy of the temporal artery as his vision disturbances presented also with episodic headaches. He was found to have an elevated rapid plasma reagin (RPR) and venereal disease research laboratory (VDRL) test in his cerebrospinal fluid (CSF) analysis. He was treated for ocular syphilis with a total resolution of his vision loss.

An Exuberant Case of Ulceronodular-Rupioid (Malignant) Syphilis in an HIV Patient: A Proposal for New Diagnostic Criteria.

We report the case of a 28-year-old male with uncontrolled human immunodeficiency virus (HIV) infection who presented with extensive ulcerated lesions with dark lamellated crusting on his face, torso, and limbs. The patient had a rapid plasma reagin (RPR) titer of 1:512, indicative of syphilis. A skin biopsy revealed granulomata surrounded by lymphocytes, histiocytes, and plasma cells, with spirochetes visible on immunohistochemical staining. The patient's rash resolved with hyperpigmented scarring after penicillin and doxycycline treatment. This severe form of secondary syphilis has been termed malignant syphilis, lues maligna, ulceronodular syphilis, or rupioid syphilis. We propose a single descriptive name for this entity, ulceronodular-rupioid syphilis. In 1969, Fisher proposed criteria for malignant syphilis based on lesion appearance, histopathologic findings, high RPR values, and rapid response to treatment. We found that the Fisher criteria were imprecise with respect to specific histopathologic findings, the quantitation of RPR values, and what constitutes rapid response to treatment. Thus, we examined an additional 74 cases from the literature and propose new diagnostic criteria based on rash appearance, histopathologic characteristics, non-treponemal and treponemal test positivity, and response to therapy. We also found that uncontrolled viremia, and not a low CD4 count, is a major risk factor for ulceronodular-rupioid syphilis in HIV patients.
