Clinical Insights: Antimicrobial Therapy for Infectious Uveitis. Ocul Immunol Inflamm 2024:1-21. [PMID: 38759216 DOI: 10.1080/09273948.2024.2345848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 04/16/2024] [Indexed: 05/19/2024]
Abstract
Infectious uveitis is a major global cause of vision impairment. Despite the eye's immune privilege, afforded by the blood-ocular barrier that restricts microbial entry, several pathogens such as bacteria, viruses, fungi, and parasites can still infiltrate and cause ocular infections and complications. Clinicians often encounter significant challenges in treating infectious uveitis due to limited or ineffective treatment options. Modern molecular techniques and imaging can aid in diagnosing and assessing intraocular infections. Various antimicrobial therapies exist, spanning topical and systemic treatments, but these are constrained by issues like drug concentration, penetration, effective duration, toxicity, and side effects. Treatment approaches also differ based on the infection's etiology. This review provides recent updates on antimicrobial therapies from a clinical perspective, covering topical, systemic, and regional treatments for infectious uveitis.

Abstract
We review key concepts in the diagnosis, treatment, and follow-up of individuals with neurosyphilis. We describe the epidemiology of syphilis in the United States, highlight populations that are markedly affected by this infection, and attempt to estimate the burden of neurosyphilis. We describe the cardinal clinical features of early and late (tertiary) neurosyphilis and characterize the clinical significance of asymptomatic neurosyphilis in the antibiotic era. We review the indications for cerebrospinal fluid (CSF) examination and the performance characteristics of different CSF assays including treponemal and lipoidal antibodies, white cell count, and protein concentration. Future biomarkers and the role of imaging are briefly considered. We review preferred and alternative treatments for neurosyphilis and evidence for their use, including evidence for the use of enhanced intramuscular benzathine penicillin G to supplement intravenous penicillin.

Could ceftriaxone be a viable alternative to penicillin for the treatment of ocular syphilis? Antimicrob Agents Chemother 2024:e0008024. [PMID: 38709007 DOI: 10.1128/aac.00080-24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 04/02/2024] [Indexed: 05/07/2024] Open
Abstract
This study was conducted to compare the effectiveness of ceftriaxone with that of aqueous crystalline penicillin G in treating ocular syphilis. We conducted a retrospective study from 2010 to 2021. Syphilis patients were administered either ceftriaxone (2 g intravenously daily for 14 days) or aqueous crystalline penicillin G [4 million units (MU) intravenously every 4 h for 14 days] as therapeutic interventions. Subsequently, we utilized these two groups to assess the serological results, cerebrospinal fluid analysis, and visual acuity at time intervals spanning 3 to 6 months post-treatment. A total of 205 patients were included, with 34 assigned to the ceftriaxone group and 171 to the penicillin group. The median age of patients was 56 years, with an interquartile range of 49-62 years, and 137 of them (66.8%) were male. Between 3 and 6 months after treatment, 13 patients (38.2%) in the ceftriaxone group and 82 patients (48.0%) in the penicillin group demonstrated effective treatment based on the clinical and laboratory parameters. The crude odds ratio (OR) was 0.672 (95% confidence interval [CI]: 0.316-1.428, P = 0.301), indicating no significant difference in effectiveness between the two groups. Thirty patients (17.5%) in the penicillin group and six patients (17.6%) in the ceftriaxone group did not experience successful outcomes. Notably, no serious adverse effects were reported in both the groups. There was no significant difference in the effectiveness of ceftriaxone and aqueous crystalline penicillin G in treating ocular syphilis. The administration of ceftriaxone without requiring hospitalization presents a convenient and safe alternative treatment option for ocular syphilis.

Abstract
Syphilis is a sexually transmitted infection, caused by the spirochete Treponema pallidum, that can lead to multi-organ involvement. In 2020, over 138,000 cases were reported in the United States equating to a case report of 40.8 per 100,000 people. Ocular syphilis is a rare manifestation and is defined as the clinical presentation of ocular disease in a person with laboratory-confirmed syphilis infection of any stage, with estimated incidence of 0.6-2% of all cases. Syphilis is known as "The Great Imitator," and can present as nearly any form of ocular disease, though the most common manifestations are posterior uveitis and panuveitis. The highly variable clinical presentation of ocular syphilis often leads to delayed diagnosis allowing the potential for poor, often preventable outcomes. This highlights the need for providers to have a high level of clinical suspicion and awareness of ocular manifestations of syphilis, especially in high risk populations. We present a case series of five patients diagnosed with ocular syphilis at a military treatment facility. Each patient had different presenting symptoms as well as different ocular manifestations.

Abstract
Importance The number of syphilis cases continues to increase in the US every year since 2001 with a 74% increase observed since 2017. In addition, there remains a national shortage of injectable penicillin G. Despite the increase in reported cases, to the authors' knowledge, there has been no recent nationwide study investigating the trends in incidence of syphilitic uveitis. Objective To evaluate the national and regional incidence of syphilitic uveitis-related hospitalizations in the US. Design, Setting, and Participants This was a retrospective, cross-sectional study. The Nationwide Inpatient Sample was queried to identify all inpatient admissions with a diagnosis of syphilitic uveitis in the US between the years 2010 and 2019. Analyses were performed to determine baseline sociodemographic characteristics and identify national and regional trends in incidence. All patients hospitalized with a diagnosis of syphilis, uveitis, and/or syphilitic uveitis were eligible for inclusion. Statistical analysis of study data took place in June 2023. Exposure Diagnosis of syphilis, uveitis, and/or syphilitic uveitis on inpatient admissions during the years 2010 to 2019 in the Nationwide Inpatient Sample. Main Outcome Measures The primary outcome was to determine trends in the national and regional incidence of syphilitic uveitis-related hospitalizations in the US. Secondary outcome measures included sociodemographic characteristics of patients with syphilitic uveitis, incidence stratified by sex and race and ethnicity, and median charge per syphilitic uveitis hospital admission. Results From the Nationwide Inpatient Sample, inpatient data from 444 674 patients (median [IQR] age, 53 [37-67] years; 54.8% male) were analyzed. There were an estimated 5581 syphilitic uveitis-related hospitalizations during the 10-year study period. The median (IQR) age of individuals with syphilitic uveitis was 45 (35-55) years, and 4395 patients (78.9%) were male. Syphilitic uveitis disproportionately affected African American individuals (1787 patients [32%], although they compose 13.6% of the population) and those belonging to the lowest median household income quartile (2163 [38.8%]). The national incidence was 0.15 per 100 000 population and showed an increasing trend over the years, with the lowest incidence in 2011 (0.08 per 100 000 population) and the highest incidence in 2019 (0.23 per 100 000 population; P = .04). Regional analysis showed an increase in incidence across all 4 US geographical regions. A total of 1293 patients (23.2%) had comorbid AIDS. Conclusion and Relevance Although this cross-sectional study only captured inpatient diagnosis, an increasing incidence of syphilitic uveitis-related hospitalizations was observed in the US between 2010 and 2019. Given the concomitant national shortage of injectable penicillin G, results suggest that clinicians should maintain a high index of suspicion for syphilis when evaluating patients with intraocular inflammation.

Abstract
The ocular and periocular manifestations of sexually transmitted infections are heterogeneous in etiology, manifestations, and complications. Etiologic agents include bacteria, viruses, parasites, and protozoa, which are most frequently transmitted via direct ocular contact with an active lesion or infected bodily fluid, autoinoculation, or dissemination from a distant site. Vertical transmission most commonly occurs perinatally during vaginal delivery. The complications of ophthalmia neonatorum can be severe, with the potential for permanent blindness or life-threatening systemic involvement if untreated. Clinical features, diagnostic modalities, and therapeutic regimens vary based on etiology and are summarized in this review. Prompt diagnosis is imperative, given the severe sequelae that may result from ocular involvement in these infections, including permanent vision loss. A multidisciplinary approach, involving both ophthalmology and dermatology, to diagnosis and management is essential to mitigate the risk of morbidity associated with sexually transmitted infections resulting in eye disease.

Abstract
Untreated syphilis can lead to ocular syphilis, otosyphilis, and neurosyphilis, conditions resulting from Treponema pallidum infection of the eye, inner ear, or central nervous system. During March-July 2022, Michigan public health officials identified a cluster of ocular syphilis cases. The public health response included case investigation, partner notification, dissemination of health alerts, patient referral to a public health clinic for diagnosis and treatment, hospital care coordination, and specimen collection for T. pallidum molecular typing. Five cases occurred among southwest Michigan women, all of whom had the same male sex partner. The women were aged 40-60 years, HIV-negative, and identified as non-Hispanic White race; the disease was staged as early syphilis, and all patients were hospitalized and treated with intravenous penicillin. The common male sex partner was determined to have early latent syphilis and never developed ocular syphilis. No additional transmission was identified after the common male partner's treatment. Due to lack of genetic material in limited specimens, syphilis molecular typing was not possible. A common heterosexual partner in an ocular syphilis cluster has not been previously documented and suggests that an unidentified strain of T. pallidum might have been associated with increased risk for systemic manifestations of syphilis. A high index of clinical suspicion and thorough sexual history are critical to diagnosing ocular syphilis, otosyphilis, and neurosyphilis. Coordination of disease surveillance with disease intervention specialist investigation and treatment referral can interrupt syphilis transmission.

Abstract
PURPOSE To describe features of a syphilitic vascularized iris mass on multimodal imaging and its resolution after penicillin treatment. METHODS Observational case report and literature review of syphilitic iris masses. RESULTS A 43-year-old woman presented with a unilateral vascularized tan iris mass in the setting of bilateral panuveitis that occurred along with bilateral papillitis, cystoid macular edema and retinal vasculitis. Laboratory work-up confirmed a diagnosis of syphilis. Ultrasound biomicroscopy (UBM) of the iris mass showed parapupillary hyperechoic full-thickness iris stromal thickening with small intrinsic circular lumens without cyst or ciliary body extension, while the anterior segment optical coherence tomography (AS-OCT) demonstrated a hyperreflective mass with deep iris extension and partial hyporeflective rim. Following treatment, the mass fully resolved without residual sequela. A review of literature identified 11 additional cases of syphilitic iris masses in the English literature from 1915 to present. Their presentations and clinical courses were reviewed herein. CONCLUSIONS This report characterizes a syphilitic iris mass on slit-lamp photography, iris fluorescein angiography, UBM and AS-OCT; depicts key characteristics of syphilitic iris masses; and highlights the need for close inspection of the iris mass as an uncommon sign of ocular syphilis.

Abstract
Syphilis is a bacterial disease caused by Treponema pallidum and is sexually transmitted via vaginal, anogenital, or orogenital contact. Vertical transmission between mother and unborn child is also possible, but transmission via skin-to-skin or blood contact is rare. The objective of this case is to highlight this rare ocular manifestation of syphilis as it manifests as a multisystemic disease affecting many organ systems. This is a case of a 46-year-old male with vision loss who was referred to the emergency department by an ophthalmologist. Two days before the presentation at the emergency department, the ophthalmologist observed the presence of optic disc edema in the left eye. At the emergency department, he complained of bright light spots in the left eye and complete darkness in the central aspect of the eyes. He reported having a non-pruritic erythematous rash on the anterior abdomen that began one week before his presentation at the emergency department. The patient also reported having multiple sexual partners. Physical examination findings showed a visual field defect in the left eye, normal bilateral eye movement, and a non-tender skin reticulation over the anterior abdominal wall. Lab results showed complete blood count (CBC) and comprehensive metabolic panel (CMP) within normal limits, fluorescent treponemal antibody (FTA) antibody reactive, human immunodeficiency virus (HIV) test and hepatitis panel negative, rapid plasma reagin (RPR) titer 1:64, and imaging results negative for any significant abnormalities. The infectious disease specialists were consulted, and the recommended IV penicillin of four million units every four hours was given. The patient reported an improvement in his blurry vision over three days. By six months, his vision was back to baseline. This case report is significant due to the rare occurrence of ocular complications as an initial presentation of syphilis. Considering the rising cases of syphilis in the United States, it is important to highlight the possibility of this uncommon clinical presentation of syphilis.

Abstract
INTRODUCTION Ocular syphilis is a rare but potentially sight-threatening manifestation of infection with the spirochete Treponema pallidum subspecies pallidum. Molecular strain typing of clinical specimens obtained from patients with syphilis can provide useful epidemiological and clinical information. In this study, we assess the utility of non-ocular clinical samples in strain typing for patients with diagnosed ocular syphilis. METHODS We collected samples of excess blood, serum, and cerebrospinal fluid (CSF) from 6 patients with ocular syphilis treated in 2013-2016. DNA was extracted, purified, and then analyzed using an enhanced molecular typing method including sequence analysis of tp0548, number of repeats in the arp gene, and restriction fragment length polymorphism of the tpr gene. RESULTS Molecular strain typing based on tp0548 gene sequence analysis revealed two cases of type F and two cases of type G in 3 of 6 (50%) cases with CSF samples, 1 of which was obtained after starting antibiotics. In a patient with 2 distinct episodes, the same tp0548 type (type G) was identified in both episodes using different sample types (CSF, whole blood). Serum samples were available in 6 cases, but none were successfully typed with any of the methods. Amplification of the tpr and arp genes was unsuccessful in all cases. Overall, strain types were identified in 4 of the 7 episodes. CONCLUSION Treponema pallidum strain types F and G were detected in CSF or whole blood in 4 of 7 episodes in this series. We demonstrate moderate sensitivity of strain typing in ocular syphilis using non-ocular clinical specimens.

Prognostic effect of HIV on visual acuity in ocular syphilis: a systematic review. Eye (Lond) 2023; 37:3271-3281.

Abstract
BACKGROUND/OBJECTIVES Ocular syphilis is a vision-threatening disease that can lead to permanent blindness if left untreated. The global re-emergence of syphilis warrants greater investigations into the visual prognosis of eyes affected by this potentially devastating disease. This systematic review investigates the impact of HIV on visual acuity (VA) outcomes in ocular syphilis. METHODS A literature search of Medline, PubMed, Embase, Clinicaltrials.gov and Cochrane Reviews was conducted for studies published between 01 January 2011 and 19 March 2022, reporting non-aggregate initial and post-treatment VA data of eyes with ocular syphilis and corresponding HIV status in patients ≥ 18 years. RESULTS A total of 95 studies, including 364 patients and 568 eyes, were evaluated. Among people living with HIV with a diagnosis of ocular syphilis, affected eyes were more likely to have optic nerve involvement and panuveitis. However, HIV status, CD4 cell count, and HIV viral load were not predictive of VA outcomes of treated ocular syphilis. Prognostic factors of final VA worse than 1.00 logMAR were female sex, the presence of macular edema, and VA ≥ 1.00 at presentation. The strongest predictor of a worse final VA was VA ≥ 1.00 at presentation. CONCLUSIONS This systematic review demonstrates that HIV status, CD4 cell count, and HIV viral load are not significant factors impacting VA outcomes of eyes with ocular syphilis. While visual prognosis is generally good, poor visual outcome is most strongly predicted by poor VA at presentation. This underscores the importance of early recognition and treatment prior to permanent vision loss.

Abstract
Ocular and systemic syphilis are well known to mimic other clinical entities making them challenging to diagnose in many cases. Syphilis testing plays an important role in diagnosis and timely treatment. Here we describe a patient with untreated human immunodeficiency virus (HIV) infection who presented with bilateral panuveitis with repeatedly negative syphilis serologies. In light of worsening retinitis while on aggressive anti-viral treatment and in consideration of the clinical suspicion for syphilitic uveitis, intravenous penicillin was initiated empirically. The patient demonstrated significant improvement subjectively and objectively after treatment. We also review and discuss syphilis testing reliability generally and in HIV co-infected patients in particular. Empiric intravenous penicillin should be considered in patients with clinical features of ocular syphilis despite negative serologic testing, especially in those with HIV co-infection.

Abstract
BACKGROUND Interventions to reduce sexually transmitted infections (STIs) among men who have sex with men (MSM) are needed. METHODS We conducted an open-label, randomized study involving MSM and transgender women who were taking preexposure prophylaxis (PrEP) against human immunodeficiency virus (HIV) infection (PrEP cohort) or living with HIV infection (persons living with HIV infection [PLWH] cohort) and who had had Neisseria gonorrhoeae (gonorrhea), Chlamydia trachomatis (chlamydia), or syphilis in the past year. Participants were randomly assigned in a 2:1 ratio to take 200 mg of doxycycline within 72 hours after condomless sex (doxycycline postexposure prophylaxis) or receive standard care without doxycycline. STI testing was performed quarterly. The primary end point was the incidence of at least one STI per follow-up quarter. RESULTS Of 501 participants (327 in the PrEP cohort and 174 in the PLWH cohort), 67% were White, 7% Black, 11% Asian or Pacific Islander, and 30% Hispanic or Latino. In the PrEP cohort, an STI was diagnosed in 61 of 570 quarterly visits (10.7%) in the doxycycline group and 82 of 257 quarterly visits (31.9%) in the standard-care group, for an absolute difference of -21.2 percentage points and a relative risk of 0.34 (95% confidence interval [CI], 0.24 to 0.46; P<0.001). In the PLWH cohort, an STI was diagnosed in 36 of 305 quarterly visits (11.8%) in the doxycycline group and 39 of 128 quarterly visits (30.5%) in the standard-care group, for an absolute difference of -18.7 percentage points and a relative risk of 0.38 (95% CI, 0.24 to 0.60; P<0.001). The incidences of the three evaluated STIs were lower with doxycycline than with standard care; in the PrEP cohort, the relative risks were 0.45 (95% CI, 0.32 to 0.65) for gonorrhea, 0.12 (95% CI, 0.05 to 0.25) for chlamydia, and 0.13 (95% CI, 0.03 to 0.59) for syphilis, and in the PLWH cohort, the relative risks were 0.43 (95% CI, 0.26 to 0.71), 0.26 (95% CI, 0.12 to 0.57), and 0.23 (95% CI, 0.04 to 1.29), respectively. Five grade 3 adverse events and no serious adverse events were attributed to doxycycline. Of the participants with gonorrhea culture available, tetracycline-resistant gonorrhea occurred in 5 of 13 in the doxycycline groups and 2 of 16 in the standard-care groups. CONCLUSIONS The combined incidence of gonorrhea, chlamydia, and syphilis was lower by two thirds with doxycycline postexposure prophylaxis than with standard care, a finding that supports its use among MSM with recent bacterial STIs.

Abstract
Uveitis is one of the most common ocular complications in people living with the Human immunodeficiency virus (HIV) and can be classified into HIV-induced uveitis, co-infection related uveitis, immune recovery uveitis, and drug-induced uveitis. The introduction of antiretroviral therapy has considerably changed the incidence, diagnosis, and treatment of different types of HIV-related uveitis. Furthermore, the specific immune condition of patients infected with HIV makes diagnosing HIV-related uveitis difficult. Recent studies have focused on the growing prevalence of syphilis/tuberculosis co-infection in uveitis. Simultaneously, more studies have demonstrated that HIV can directly contribute to the incidence of uveitis. However, the detailed mechanism has not been studied. Immune recovery uveitis is diagnosed by exclusion, and recent studies have addressed the role of biomarkers in its diagnosis. This review highlights recent updates on HIV-related uveitis. Furthermore, it aims to draw the attention of infectious disease physicians and ophthalmologists to the ocular health of patients infected with HIV.

Abstract
BACKGROUND In accordance with worldwide data, the Robert Koch Institute (RKI) has reported a constant increase of syphilis cases in Germany over the past decade. METHODS We analysed the data of all patients, referred to a Department of Ophthalmology in a tertiary referral centre in Düsseldorf, Germany between 2008 and 2019, who were tested for syphilis. The epidemiologic, demographic, clinical, diagnostic and therapeutic data were retrieved from the records and evaluated in a retrospective, descriptive, non-comparative study. RESULTS Syphilis serology was positive in 32/1840 (1.7%) patients, and was evenly distributed over this period. 26 (81.3%) were male, 19 (59.4%) belonged to a risk group. Ocular syphilis was the primary diagnosis for 29 patients (90.6%). The most frequent manifestation was uveitis (n = 20, 62.5%). By the end of therapy, 19 patients (59.4%) had an improved visual acuity. CONCLUSION The incidence of ocular syphilis cases has remained stable over the last decade.

Clinical features and incidence of visual improvement following systemic antibiotic treatment in patients with syphilitic uveitis. Sci Rep 2022; 12:12553. [PMID: 35869241 PMCID: PMC9307809 DOI: 10.1038/s41598-022-16780-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 07/15/2022] [Indexed: 11/15/2022] Open
Abstract
To describe the clinical features, longitudinal pattern, and incidence rate of improvement of visual acuity (VA) following antibiotic therapy in patients with syphilitic uveitis. A total of 36 patients were included in this retrospective study from 2009 to 2020. The longitudinal patterns of mean VA values during follow-up were analyzed using a linear mixed model. Most patients were men with HIV coinfection (81%) and presented with panuveitis (49%). The mean VA at baseline improved from 0.97 to 0.39 logMAR at 6 months and remained stable thereafter. The cumulative incidence of VA ≥ 20/25 achieved by 2 years was 70%. Receiving antibiotic therapy within four weeks of the onset of ocular symptoms (adjusted hazard ratio [aHR] 3.4, P = 0.012), absence of HIV coinfection (aHR 8.2, P < 0.001), absence of neurosyphilis (aHR 6.5, P = 0.037), better presenting VA (aHR 5.0, P = 0.003), and intermediate uveitis as opposed to panuveitis (aHR 11.5, P = 0.013) were predictive of achieving VA ≥ 20/25. Men with HIV coinfection represented the majority of our patients. Visual outcomes, in response to antibiotics, were favorable. Delayed treatment, poor presenting VA, presence of HIV coinfection, and concomitant neurosyphilis decreased the likelihood of VA restoration.

Abstract
Objectives To define the clinical features of ocular syphilis and analyze the cerebrospinal fluid (CSF) of ocular syphilis patients to determine the co-occurrence of neurosyphilis. Methods This was a retrospective study of 17 patients (23 eyes) with ocular syphilis admitted to the Fifth People's Hospital, Suzhou, China from September 2017 to December 2021. Clinical manifestations, laboratory tests, treatment, and clinical outcomes were analyzed, and a review was conducted. Results Eight males (12 eyes) and nine females (11 eyes) were enrolled. Mean patient age was 49.06 ± 3.47 years. The total manifestation time for ocular symptoms ranged from 10 days to 6 years. The cohort was comprised of three cases of early syphilis, four cases of late syphilis, and ten cases of unknown stage. The primary complaints were decreased visual acuity in 15 cases (21 eyes), ptosis in 1 case (1 eye), and loss of light perception in 1 case (1 eye). Cases were diagnosed as chorioretinitis in 7 cases (8 eyes), optic nerve retinitis in 4 cases (6 eyes), optic neuritis in 4 cases (7 eyes), and oculomotor nerve palsy in 1 case (1 eye), syphilitic stromal keratitis in 1 case (1 eye). Serum HIV antibody was positive in one case(Nos.2). All patients had reactive serum Treponema Pallidum Particle Agglutination (TPPA) and Toluidine Red Unheated Serum Test (TRUST). All patients underwent CSF examination. CSF white blood cell count was ≥5 × 106/L in 13 cases, CSF protein was >500 mg/L in 6 cases, TPPA was reactive in 15 cases, and TRUST was reactive in 5 cases. Eleven cases were also diagnosed with neurosyphilis. Patients were treated with either penicillin G sodium or ceftriaxone sodium. At time of discharge, 12 patients reported improved visual acuity. Abnormal serum or CSF examination improved in ten patients during the 6–12 month follow-up. Conclusion Visual acuity loss is a warning indicator of ocular syphilis. Ocular syphilis primarily manifests as posterior uveitis, involving the choroid, retina, and optic nerve, and often co-occurs with neurosyphilis. Effective treatment should be administered immediately to avoid irreversible visual impairment and other serious adverse outcomes.

Abstract
Ocular syphilis has a wide range of presentations; however, the most common findings are ophthalmalgia, blurry vision, and erythematous conjunctiva. This report presents a case of ocular syphilis in a human immunodeficiency virus-positive patient with an allergy to penicillin. On presentation, the patient was diagnosed using a fluorescent treponemal antibody absorption test, in addition to rapid plasma reagin. In this case, the patient received alternative treatment with doxycycline prior to penicillin desensitization, with marked improvement of his symptoms.

Abstract
AIM To evaluate the clinical characteristics, demographics, and visual outcomes of patients with ocular syphilis at an urban hospital to increase awareness and assist in earlier diagnosis and treatment of the resurgent disease. METHODS A retrospective chart review was performed on patients with ICD-9 and ICD-10 diagnosis codes correlating with syphilis or syphilis-related ocular diseases between 2010 and 2019. Variables evaluated included age, gender, race, vision, ocular findings, human immunodeficiency virus (HIV) status and men who have sex with men status, recreational drug and alcohol use. RESULTS Ocular syphilis was diagnosed in 40 patients (53 eyes) of a total of 229 patients who tested positive for syphilis via serum and/or cerebrospinal fluid treponemal testing from 2010-2019. Among patients with ocular syphilis, most patients were males, aged 45 or above and Black, and had no diagnosed HIV infection. Approximately 50% patients had 20/40 vision or better. Nearly 50% had non-granulomatous anterior uveitis as their initial presentation, and 49% of patients had involvement of the posterior segment. Neovascular glaucoma (5.7%), papillitis (7.5%), vasculitis (5.7%), and retinal detachment (5.7%) were rarer presentations of the disease and were associated with a poorer visual prognosis. CONCLUSION Given the increased prevalence and protean manifestations of syphilis, early diagnosis and treatment are paramount. More studies on ocular syphilis are warranted to understand this resurging disease.

Abstract
PURPOSE To evaluate the clinical characteristics and visual outcomes of ocular syphilis in human immunodeficiency virus (HIV)-positive and negative patients. METHODS We performed a retrospective chart review of all patients with newly diagnosed ocular syphilis between January 2015 and August 2021. RESULTS 68 eyes of 41 patients (22 eyes in 12 HIV-positive patients, 46 eyes in 29 HIV-negative patients) were included. The most common ophthalmic feature was posterior uveitis in HIV-positive and anterior uveitis in HIV-negative patients; 58.3% (7 out of 12 patients) of HIV-positive and 48.2% (14 out of 29 patients) of HIV-negative patients were diagnosed with neurosyphilis. There were no significant differences in laterality, presence of concurrent rash, rapid plasma reagin (RPR) titers, presenting, and final corrected visual acuity between both groups. CONCLUSION Nearly one-fifth of eyes may suffer from severe visual loss of ≤ 20/200. HIV co-infection may not result in visual outcomes in syphilis.

Abstract
Objectives: This study aims to describe the demographic features, clinical profile, Human Immunodeficiency Virus (HIV) status, and visual outcome after completing treatment in patients diagnosed with uveitic syphilis. Methods: A retrospective review was conducted of all cases diagnosed with ocular syphilis from January 2014 to December 2019 at the ophthalmology clinic of Selayang Hospital, Selangor, Malaysia. A total of 31 cases were reviewed, and the collected data included demographic features, history of high-risk behavior, ocular symptoms and signs, visual acuity at presentation and after completing treatment, treatment received, complications, and HIV status. Serology tests to confirm the diagnosis were also included, such as the rapid plasma reagin (RPR), venereal disease research laboratory test (VDRL) titer, and treponema pallidum hemagglutination (TPHA) tests, and some cases also included the VDRL cerebrospinal fluid (CSF) test. Results: A total of 31 patients with ocular syphilis were identified within the study period. Male patients comprised the majority with 27 cases. Nineteen patients were below the age of 50. The majority were ethnic Malay (21 patients). Seventeen patients were identified to have HIV co-infection. Twenty patients reported high-risk behaviors, and among them, six cases were HIV-infected homosexuals. The commonest symptom was blurring of vision (61%), followed by eye redness (16%), floaters (13%), and incidental findings (10%). There were 18 bilateral cases and 13 unilateral cases. The larger share presented as panuveitis (14 cases), followed by intermediate uveitis (nine cases), anterior uveitis (four cases), posterior uveitis (two cases), endophthalmitis (one case), and branch retinal vein occlusion (one case). RPR and TPHA tests were done for all patients. Only 12 patients consented to lumbar puncture for a CSF VDRL test, and one tested positive. All patients received intravenous (IV) administration of 3.0 to 4.0 million units of benzylpenicillin every four hours for 14 days. All cases reported a good outcome with an improvement in visual acuity of at least two Snellen lines after treatment. Conclusion: Early detection and treatment of ocular syphilis will usually preserve visual acuity and ocular function. This study highlights the need for a high degree of suspicion of HIV co-infection, as the majority of our patients were discovered to be HIV-seropositive. Thus, HIV screening is mandatory in all patients presenting with syphilitic uveitis.

Abstract
PURPOSE We describe the development and management of choroidal neovascularization (CNV) in a patient with acute syphilitic posterior placoid chorioretinitis (ASPPC). METHODS A retrospective case review is presented. RESULTS A 66-year-old man presented with unilateral blurry vision. He had a history of systemic syphilis infection twice, the last diagnosed 15 years before presentation and treated with intravenous ceftriaxone, resulting in seroreversion of an initially positive rapid plasma reagin (RPR). Examination revealed ASPPC with subfoveal CNV. Repeat testing revealed an RPR titer of 1:16 384. He was treated with 6 monthly intravitreal injections of bevacizumab and systemic antibiotics, resulting in resolution of his ASPPC and regression of his CNV. CONCLUSIONS CNV is a rare complication of ASPPC. Multimodal imaging can be useful to suggest the diagnosis, and prompt treatment with systemic antibiotics and intravitreal anti-vascular endothelial growth factor agents can lead to resolution of ASPPC and regression of CNV, respectively.

Abstract
A panel of experts generated 5 "key questions" in the management of adult syphilis. A systematic literature review was conducted and tables of evidence were constructed to answer these questions. Available data suggest no clinical benefit to >1 dose of benzathine penicillin G for early syphilis in human immunodeficiency virus (HIV)-infected patients. While penicillin remains 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 are very limited data regarding the impact of additional antibiotic doses on serologic responses in serofast patients and no data on the impact of additional antibiotic courses on long-term clinical outcomes. In patients with isolated ocular or otic signs and symptoms, reactive syphilis serologic results, and confirmed ocular/otic abnormalities at examination, a diagnostic cerebrospinal fluid (CSF) examination is not necessary, because up to 40% and 90% of patients, respectively, would have no CSF abnormalities. Based on the results of 2 studies, repeated CSF examinations are not necessary for HIV-uninfected patients or HIV-infected patients on antiretroviral therapy who exhibit appropriate serologic and clinical responses after treatment for neurosyphilis. Finally, several important gaps were identified and should be a priority for future research.

Abstract
BACKGROUND Syphilis is a systemic, infectious disease caused by Treponema pallidum and is notorious for the variety of its clinical presentations. OBJECTIVE We report a case of secondary syphilis with thyroid gland and ocular involvement in a human immunodeficiency virus (HIV) negative patient. METHODS We present the patient's history, clinical findings, laboratory test results, imaging and management. RESULTS A 39-year-old Caucasian, HIV unaffected woman presented with acute midline neck swelling, dyspnea and difficulty to talk or swallow. Serologic tests for syphilis were positive. PCR performed on a thyroid fine needle aspiration cytology (FNAC) aspirate was positive for Treponema pallidum. Skin lesions and unilateral loss of vision were present. Treatment with intravenous benzyl-penicillin showed a good regression of symptoms. CONCLUSION We report an unusual case of thyroid swelling in a secondary syphilis infection. Awareness of syphilis as a differential diagnosis is important in a risk population.

Abstract
Syphilis, a sexually transmitted infection caused by the spirochete Treponema pallidum, generally presents in distinct stages that sequentially progress in a predictable pattern. However, in the case of syphilis and HIV coinfection, the progression of the disease may be atypical, and syphilis may be the initial presentation of an underlying HIV infection in an undiagnosed patient. These patients can initially present with symptoms of secondary syphilis and can have a rapid and aggressive initial course. Here we describe a case of syphilis in a patient who presented in the secondary stage with a diffuse maculopapular rash, who was later found to have an underlying HIV coinfection.

Abstract
BACKGROUND In the era of the re-emergence of syphilis, ocular syphilis has gained attention because its prevalence has increased and it can cause blindness and disability. OBJECTIVES To investigate the clinical presentation and prognosis of ocular syphilis. METHODS Prospective study on 53 patients (90 eyes) with ocular syphilis diagnosed at the Santa Casa of Belo Horizonte, Brazil. The diagnosis was based on clinical manifestations of the disease and on serological markers (positive serum treponemal and non-treponemal tests or two positive treponemal tests). RESULTS Thirty-five eyes (66%) were from men and the mean age was 45.3 ± 12.0 years. HIV coinfection was confirmed in 10 patients (18.9%). Forty-four (84.9%) had VDRL titers ≥ 1:32. Bilateral ocular involvement occurred in 68%. Optic neuritis was diagnosed in 51.7% of the eyes and uveitis in 48.2%. Regarding visual acuity, the median baseline logarithm of the minimum angle of resolution (logMAR) was 1 (20/200 Snellen), while after antibiotic therapy, the median was 0.2 (20/30 Snellen). Poor visual acuity after treatment, defined as the best-corrected visual acuity (BCVA; logMAR 1; 20/200 Snellen) or worse, was associated with severe BCVA at presentation (below logMAR 1.3; 20/400 Snellen) (p = 0.001) and age over 50 years (p = 0.001). CONCLUSIONS This study confirms the wide spectrum of clinical manifestations of ocular syphilis. The most frequent form was optic neuritis, an important differential diagnosis from other causes of inflammatory neuritis. Early diagnosis is essential, given that this is a treatable condition with excellent visual recovery in most cases.

Abstract
PURPOSE To determine classification criteria for syphilitic uveitis. DESIGN Machine learning of cases with syphilitic uveitis and 24 other uveitides. METHODS Cases of anterior, intermediate, posterior, and panuveitides were collected in an informatics-designed preliminary database, and a final database was constructed of cases achieving supermajority agreement on the diagnosis, using formal consensus techniques. Cases were analyzed by anatomic class, and each class was split into a training set and a validation set. Machine learning using multinomial logistic regression was used on the training set to determine a parsimonious set of criteria that minimized the misclassification rate among the different uveitic classes. The resulting criteria were evaluated on the validation set. RESULTS Two hundred twenty-two cases of syphilitic uveitis were evaluated by machine learning, with cases evaluated against other uveitides in the relevant uveitic class. Key criteria for syphilitic uveitis included a compatible uveitic presentation (anterior uveitis; intermediate uveitis; or posterior or panuveitis with retinal, retinal pigment epithelial, or retinal vascular inflammation) and evidence of syphilis infection with a positive treponemal test. The Centers for Disease Control and Prevention reverse screening algorithm for syphilis testing is recommended. The misclassification rates for syphilitic uveitis in the training sets were as follows: anterior uveitides 0%, intermediate uveitides 6.0%, posterior uveitides 0%, panuveitides 0%, and infectious posterior/panuveitides 8.6%. The overall accuracy of the diagnosis of syphilitic uveitis in the validation set was 100% (99% confidence interval 99.5, 100)-that is, the validation set's misclassification rates were 0% for each uveitic class. CONCLUSIONS The criteria for syphilitic uveitis had a low misclassification rate and seemed to perform sufficiently well for use in clinical and translational research.

Abstract
Multiple studies around the world suggest that syphilis is re-emerging. Ocular syphilis - with a wide range of presentations, most of which are subtypes of uveitis - has become an increasingly common cause of ocular inflammation over the past 20 years. Its rising incidence, diagnostic complexity, and manifestations that have only recently been characterized make ocular syphilis relevant from the public health, clinical, and scientific perspectives. We review the demographics, epidemiology, clinical features, ocular imaging findings, diagnosis, and medical management of this condition.

Abstract
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.

Abstract
Purpose: To analyse posterior segment optical coherence tomography (OCT) findings in ocular syphilis.Methods: Medical records of 54 patients presenting consecutively with syphilitic uveitis were reviewed. Vitreous, retina and choroid (one eye/patient) were assessed by spectral-domain OCT on presentation (54 eyes) and after treatment (31 eyes). Improvement in signs and associations between presenting signs and final best corrected visual acuity (BCVA) were determined by McNemar's and Fisher's exact tests.Results: Early inner retinal OCT findings included hyperreflective dots (n = 49, 91%), tongue-like projections (n = 44, 81%) and large rounded spots (n = 41, 76%). Common outer retinal findings included thickening, irregularity, elevations and/or detachment of retinal pigment epithelium (n = 46, 85%), and disruption or loss of the ellipsoid zone (n = 33, 61%). Most outer retinal changes resolved with treatment (p < .05), and common presenting signs were not associated with poor final BCVA (p > .05).Conclusion: OCT findings have diagnostic value in ocular syphilis, but do not predict prognosis.

Abstract
Syphilis is a sexually transmitted, systemic, inflammatory disease caused by the spirochaete, Treponema pallidum. The natural history of untreated syphilis progresses through four distinct stages: primary, secondary, latent, and tertiary syphilis. Ocular involvement can occur at any stage of syphilis and any part of the eye can be affected. With the exception of syphilitic posterior placoid chorioretinitis, the diverse manifestations of ocular syphilis have few distinct features that can be used to assist in clinical diagnosis. Therefore, ocular syphilis should always be a part of the differential diagnosis of most, if not all, ocular infectious and inflammatory presentations. Specifically, uveitis presentations, high-risk sexual history, illicit drug use history, treatment failure, prior history of syphilis should prompt further diagnostic workup for ocular syphilis. A presumptive diagnosis of ocular syphilis relies on serological testing, both treponemal and nontreponemal tests. All patients with ocular syphilis should have their cerebrospinal fluids tested for the co-existence of neurosyphilis and their blood tested for human immunodeficiency virus co-infection. In the United States, Centers for Disease Control and Prevention recommend that ocular syphilis be managed according to its treatment guidelines for neurosyphilis, with parenteral aqueous crystalline penicillin G the drug of choice. With the timely diagnosis and appropriate treatment, ocular syphilis is curable. However, delayed diagnosis of ocular syphilis may result in long-term visual impairment. Delayed diagnosis occurs because of its diverse presentations mimicking other ocular diseases, and failure of the clinician to order serological testing. With the recent worldwide resurgence of ocular syphilis, clinicians should be familiar with the manifestation, diagnosis, and treatment of ocular syphilis.

Abstract
BACKGROUND The purpose of this study was to estimate the cost of syphilis in the United States, in terms of the average lifetime direct medical cost per infection. METHODS We used a decision tree model of the natural history of syphilis. The model allowed for numerous possible outcomes of infection, including treatment for syphilis at various stages, inadvertent treatment, and late syphilis outcomes in those who are alive and still infected 30 years after acquisition. Future costs were discounted at 3% annually. Model inputs, such as the cost and probability of each outcome, were based on published sources. The probabilities we applied yielded outcomes consistent with reported cases of syphilis by stage from national surveillance data and number of deaths due to late syphilis from national mortality data. RESULTS The estimated, discounted lifetime cost per infection was $1190 under base case assumptions (2019 dollars). Treatment costs associated with late syphilis outcomes, such as cardiovascular syphilis, accounted for only $26 of the average lifetime cost per infection. Results were most sensitive to assumptions regarding the treatment cost per case of unknown duration or late syphilis. In the probabilistic sensitivity analyses, the 2.5th and 97.5th percentiles of the 10,000 simulations of the lifetime cost per infection were $729 and $1884, respectively. CONCLUSIONS Our estimate of the lifetime cost per infection is about 50% higher than in a previous study, a difference due in large part to our higher cost assumptions for benzathine penicillin G.

Abstract
PURPOSE OF REVIEW In the context of a resurgence of syphilis worldwide, it can be anticipated that a rise in cases of ocular, otic, and neurosyphilis will also be seen. This article reviews the current epidemiology, manifestations, and approach to management and treatment. RECENT FINDINGS Although studies continue investigating alternate approaches and new diagnostic tests for ocular and neurosyphilis, few data exist to change current diagnostic algorithms and approaches to diagnosis, management, or follow up. SUMMARY The diagnosis of neurologic and eye/ear involvement with syphilis may be delayed because of a lack of specificity of findings, low suspicion for syphilis, fluctuation in symptoms, and/or similarities in presentation to other diseases. A high index of suspicion for syphilis and re-education about the protean manifestations of syphilis by all clinicians is required provide timely diagnosis and management of ocular, otic, and neurosyphilis.

Human Immunodeficiency Virus Seropositivity and Early Syphilis Stage Associated With Ocular Syphilis Diagnosis: A Case-control Study in British Columbia, Canada, 2010-2018. Clin Infect Dis 2021; 71:259-266. [PMID: 31420644 DOI: 10.1093/cid/ciz794] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2019] [Accepted: 08/13/2019] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND The incidence of syphilis has been increasing worldwide in the last 20 years, disproportionately impacting those living with human immunodeficiency virus (HIV). Alongside this increase, several jurisdictions have reported increasing incidences of syphilis-related complications, including ocular syphilis. We sought to characterize ocular syphilis cases in British Columbia (BC), Canada. METHODS This case-control study compared ocular syphilis cases, matched (1:4) to syphilis controls, that were diagnosed in BC between January 2010 and December 2018. Multivariable logistic regression was used to identify potential correlates of ocular syphilis, where variables were included in the final model if significant (P ≤ .05). RESULTS During the study period, there were 6716 syphilis diagnoses, including 66 (0.98%) ocular syphilis cases. The median age of cases was 49.5 years (interquartile range 39-59). Most (87.8%) patients were male, where 54.6% identified as men who have sex with men. The most common ophthalmologic diagnosis was panuveitis (42.4%). Of ocular syphilis patients, 48.5% were living with HIV at the time of their syphilis diagnosis, compared to 26.4% of controls (P = .001). The proportion of syphilis cases with ocular syphilis increased from 0.48% in 2010 to 0.83% in 2018. The final multivariable model demonstrated correlates between ocular syphilis and early syphilis stage, including primary/secondary (odds ratio [OR] 4.96, 95% confidence interval [CI] 1.86-13.24) and early latent (OR 4.29, 95% CI 1.62-11.34) stages, and HIV serostatus (OR 2.16, 95% CI 1.14-4.09). CONCLUSIONS Ocular syphilis increased over the study period, both in absolute numbers and as a proportion of all syphilis cases, a finding consistent with other jurisdictions. These findings highlight the importance of vigilance for ocular syphilis, to avoid diagnostic and treatment delays.

Abstract
PURPOSE OF REVIEW Neurosyphilis (NS) and Lyme neuroborreliosis (LNB) are spirochetal diseases with distinct clinical manifestations. The diagnosis of NS remains challenging due to imperfect diagnostic criteria and testing modalities. With LNB, misconceptions about diagnosis and treatment lead to considerable morbidity and drug related adverse effects. RECENT FINDINGS Although studies continue investigating alternate approaches and new diagnostic tests for NS, few data exist to change current approaches to diagnosis, management or follow up. In the diagnosis of LNB, the chemokine CXCL13 shows promising diagnostic accuracy. A systematic review discourages the use of cell-based assays when investigating Lyme disease. Clinical studies show no benefit from extended antibiotic treatment for patients with unspecific symptoms labelled as having Lyme disease. SUMMARY The diagnosis of NS may be delayed due to a lack of specificity of findings, low suspicion for syphilis, and/or similarities in presentation to other diseases. A high index of suspicion for syphilis is required provide timely diagnosis and management of NS. Fortunately, penicillin remains the treatment of choice. Overdiagnosis and overtreatment in patients labelled as having Lyme disease can be avoided by an evidence-based approach towards diagnosis and treatment.

Abstract
In recent years, syphilis (Treponema pallidum) has become increasingly prevalent in Canada, and as a result, rates of ocular syphilis are also rising. Classically, syphilis was seen primarily in men who have sex with men; now, it is increasingly seen in people of all age groups, sexes, and sexual orientations. We present a series of 26 cases of ocular syphilis from London, Ontario, 5 of which are discussed in detail to illustrate the varied presentations and diagnostic challenges of ocular syphilis. The presentations include uveitis, iris granuloma (gumma), retinitis (acute syphilitic posterior placoid chorioretinitis), vasculitis, optic neuritis, and serous retinal detachment. The 5 cases are mostly middle-aged heterosexual men and women without the typical risk factors that would alert the examiner to suspect syphilis. We emphasize the importance of testing for syphilis when assessing and treating inflammatory eye disease, regardless of demographics and known risk factors, given the increasing prevalence of this disease. Diagnosis of syphilis relies on serologic testing, which is complex and has undergone significant changes from historical reliance on the Venereal Disease Research Laboratory test. We provide an overview of the strategy and rationale for modern serologic testing. The mainstay of treatment remains intravenous penicillin G, with alternative antibiotics (e.g., ceftriaxone) being less effective.

Abstract
Purpose: This work describes the characteristics and unique features of ocular syphilis. Methods: Ten serologically proven cases of ocular syphilis were retrospectively analyzed. Results: Eighteen eyes of 10 patients were affected. Nine of 10 patients were male and the mean age was 58 years (range, 36-81 years). HIV antibody testing was positive in 3 patients (30%). Five cases were first diagnosed by an ophthalmologist. One patient presented with a syphilitic rash. The most common ocular findings were panuveitis (n = 6) and cystoid macular edema (n = 4). Ocular involvement was unilateral in 2 cases and bilateral in 8. Best-corrected visual acuity improved in 13 of 18 eyes (72%) after treatment. Three cases developed recurrent retinal detachments that required repair with silicone oil. Conclusions: Most cases were HIV negative. Syphilitic uveitis can be the initial presentation of syphilis without classic systemic manifestation. Ophthalmologists play an important role in the diagnosis and treatment of syphilis.

Abstract
OBJECTIVES Since the 2000s, there has been an increase in prevalence of neurosyphilis (NS) and ocular syphilis (OS). As data about symptomatic NS/OS is limited, this study aims to assess the characteristics of symptomatic NS/OS, according to HIV status. METHODS We compared the clinical and biological presentation of early symptomatic NS/OS and its outcome in HIV-positive and HIV-negative patients. RESULTS Ninety-six patients (93% men, 49% HIV-positive) were included from 2000 to 2016 in two centers, with 67 (69%) having OS, 15 (16%) NS, and 14 (14%) both. HIV-positive patients were younger (P=0.006) and more likely to be males having sex with males (P=0.00048) or to have a history of syphilis (P=0.01). Among 81 OS, there were 43 posterior uveitis (57%), and bilateral involvement was more common in HIV-positive patients (62% versus 38%, P=0.045). Among 29 NS there were 21 cases of cranial nerve involvement (72%), seven meningitis (24%) and 11 paresthesia (38%). Involvement of the VIIIth cranial nerve was the most common (16 cases). Treponemal tests were more commonly found positive in cerebrospinal fluid in HIV-positive patients (88% versus 76%, P=0.04). Visual acuity (VA) always improved after treatment (initial VA logMAR 0.8±0.8 versus 0.1±0.1 at 3 months), but 32% and 18% of the patients still had neurological or ocular impairment respectively six and 12 months after treatment. Non-treponemal serological reversion was observed in 43/50 patients (88%) at six months. CONCLUSION HIV infection has no consequence on the outcome of NS and OS. Sequelae are common, emphasizing the importance of prevention, and screening, and questioning enhanced treatment.

Abstract
Otosyphilis is a serious complication of syphilis.329 participants enrolled in a study of cerebrospinal fluid (CSF) abnormalities in syphilis underwent portable audiometry (250 Hz to 8000 Hz at 5-75 dB); it was repeated in 33 after otosyphilis treatment. Treponema pallidum spp pallidum (T. pallidum) DNA in blood was quantitated by polymerase chain reaction. Odds ratios (ORs) or hazard ratios (HRs) with 95% confidence intervals (CIs) were determined by logistic, ordinal or Cox regression.166 (50.5%) had normal hearing; 15 (4.6%) had low frequency (LF) loss alone, 93 (28.3%) had high frequency (HF) loss alone, and 55 (16.7%) had both. Adjusted odds of any hearing loss were higher with detectable blood T. pallidum DNA (3.00 [1.58-5.69], p = 0.001), CSF pleocytosis (2.02 [1.12-3.66], p = 0.02), and older age (2.22 per 10-year increase, [1.70-2.91], p < 0.001). HRs of normalization of LF and HF loss were lower for older individuals (0.20 [0.07-0.63, p = 0.005] and 0.22 [0.05-0.94, p = 0.04]), and HRs for normalization of HF loss were lower for those with more severe loss (0.09 [0.02-0.43], p = 0.002), and in those with CSF pleocytosis (0.32 [0.11-0.96], p = 0.04).Older age and CSF pleocytosis increase the likelihood of otosyphilis and impair hearing recovery after otosyphilis treatment.

Abstract
Onychoptosis is the periodic shedding and falling of one or more nails, in whole or part. It can be seen after fever, trauma, adverse reaction to medications, and in systemic illnesses including syphilis (syphilitic onychia). We report a case of 38-year-old man presented with subacute bilateral retrobulbar optic neuritis. Physical examination revealed diffuse onychoptosis which lead into the diagnosis of neurosyphilis. Symptoms significantly improved with appropriate treatment with intravenous penicillin G for 14 days.

Abstract
Congenital syphilis (CS) rates reached a 20-year high in the United States in 2018. Unlike previous years, most babies diagnosed with CS were born to mothers who received prenatal care, indicative of the need for better provider education and guideline adherence. Current rates suggest that screening for syphilis should be performed at the first prenatal care visit and twice during the third trimester. There are two diagnostic algorithms available for use in the United States (traditional and reverse) and providers must understand how to perform each algorithm. Treatment should be administered according to stage of syphilis per Centers for Disease Control recommendations with best neonatal outcomes seen when treatment is initiated >30 days before delivery. Benzathine Penicillin G remains the only recommended treatment of syphilis during pregnancy. In viable pregnancies, a pretreatment ultrasound is recommended to identify sonographic evidence of fetal infection and treatment should be initiated with continuous fetal monitoring to evaluate for the Jarisch-Herxheimer reaction which can cause preterm labor and fetal distress. After adequate syphilotherapy, a fourfold decline in maternal nontreponemal titers may not be observed by delivery and does not correlate with rates of CS.
