Clinical characteristics and outcomes of people living with HIV and ocular syphilis during the COVID-19 health emergency.

BACKGROUND: The global shift in healthcare during the COVID-19 pandemic led to challenges in the care of people living with HIV. METHODS: We conducted a retrospective study that aimed to delineate sociodemographic, clinical characteristics and outcomes, of people living with HIV diagnosed with ocular syphilis. RESULTS: Fifty-three people living with HIV were identified with ocular syphilis. Thirty-eight (71.6%) presented ocular symptoms. Twenty-three (43.3%) underwent lumbar puncture, 5 (9.4%) were positive for neurosyphilis. Forty-seven (88.6%) received treatment, 32 (68%) received standard treatment with aqueous crystalline penicillin G, and 15 (31.9%) were treated with alternative regimens due to the impossibility of hospitalization. Six (11.3%) individuals were lost to follow-up and/or did not receive treatment. Eighteen (56.2%) out of 32 individuals in the aqueous crystalline penicillin G group experienced serological response, 5 (15.6%) experienced treatment failure, and 9 (28.1%) were lost to follow-up. In the alternative therapy group, 12 out of 15 individuals (80%) experienced serological response. One (6.7%) experienced treatment failure, and 2 (13.3%) were lost to follow-up. CONCLUSIONS: During the COVID-19 health emergency in Mexico, alternative treatments for ocular syphilis demonstrated favorable clinical outcomes amid challenges in accessing hospitalization.

Optic neuritis secondary to syphilis.

Optic neuritis is a rare manifestation of syphilis, and the involvement of the central nervous system should be considered synonymous with neurosyphilis. This infectious disease, well known as the great imitator, can affect any structure and produce multiple clinical symptoms. Here, we report a case of a 62- year-old male patient who presented to our service with decreased vision and myodesopsias in right eye. The posterior segment showed a hyperemic nerve with peripapillary hemorrhages and retinal pigment epithellium hyperplasia. The patient was recently diagnosed with HIV. Serology for syphilis was positive with posterior decreased levels of nontreponemal test following treatment with ceftriaxone. Optic neuritis can occur at any stage of syphilis and must always be considered a differential diagnosis.

Psychiatric manifestations of neurosyphilis over past two decades: Findings from a tertiary care neuropsychiatric hospital in south India.

OBJECTIVE: To assess presentation of neurosyphilis with a focus on the psychiatric aspects. METHOD: File review of the cases with a positive cerebrospinal fluid venereal disease research laboratory test between 1999 to 2020. RESULTS: Medical records of 143 neurosyphilis patients were analysed. Hallucinations, delusions, and catatonia were the commonest psychiatric symptoms. Brain atrophy was the commonest neuroimaging finding. The number of neurosyphilis patients and the proportion with delirium or catatonia declined during the second decade (2010-2020). CONCLUSION: Atypical presentation of psychiatric symptoms around the fifth decade, with associated neurological symptoms or brain imaging changes, should prompt evaluation for neurosyphilis.

Enhancing clinical awareness: retrospective analysis of neurosyphilis cases and diagnostic predictors for early recognition and treatment.

OBJECTIVE: This is a retrospective analysis of clinical data from individuals diagnosed with neurosyphilis, aiming to enhance healthcare professionals' understanding of the disease and expedite early diagnosis and intervention. METHODS: A retrospective analysis was conducted on the clinical records of 50 patients who received a diagnosis of symptomatic neurosyphilis and were admitted to the Neurology Department during the period spanning January 2012 to December 2022. RESULTS: Clinical manifestations encompassed diverse phenotypes, with syphilitic meningitis accounting for 16% of cases, characterized by symptoms such as headache, blepharoptosis, paralysis, blurred vision, and tinnitus. Meningovascular syphilis presented in 36% of cases, exhibiting episodic loss of consciousness, limb numbness, and limb convulsion. Paralytic dementia manifested in 36% of cases, featuring symptoms such as memory loss, sluggish response, and slow movement. Tabes dorsalis was observed in 12% of cases, presenting with weakness, numbness, and staggering. Routine cerebrospinal fluid (CSF) analysis indicated abnormal white blood cell counts in 60% of patients, while biochemical testing revealed abnormal protein content in 52% of patients. Notably, statistically significant differences were observed between patients with interstitial and parenchymatous neurosyphilis (Z = 2.023, P = 0.044) in terms of CSF protein content. Electroencephalogram (EEG) results were abnormal in six patients, and imaging studies unveiled diverse findings in 46 patients. CONCLUSION: The study highlights the importance of neurological and/or ocular symptoms in diagnosing symptomatic neurosyphilis. Individuals with hypomnesia should be closely monitored for potential neurosyphilis. Integrating clinical manifestations, laboratory tests, EEG, and imaging can reduce misdiagnosis. This comprehensive approach shows promise in improving early identification and management of neurosyphilis.

Epstein-Barr virus-positive monoclonal lymphoplasmacytic proliferation associated with neurosyphilis in an immunocompetent patient: A case report.

Syphilis is an infectious disease caused by the spirochete bacterium Treponema pallidum. Neurosyphilis results from the infection of the nervous system with Treponema pallidum, which can occur at any stage of syphilis. Neurosyphilis is often overlooked because of its rarity. Early-stage neurosyphilis with brain mass formation is rare. We present a case of early-stage neurosyphilis with prominent Epstein-Barr virus (EBV)-positive monoclonal lymphoplasmacytic proliferation in an immunocompetent patient. A 36-year-old man presented with a chief complaint of a progressively worsening headache, a newly developed skin rash, and a fever. Magnetic resonance imaging showed a mass lesion, which measured 18 mm in diameter, in the left frontal lobe of the cerebrum. The patient underwent an emergency operation to remove the abscess. A pathological investigation revealed complex findings. There was an abscess in the cerebrum. Lymphoplasmacytic meningitis was also noted. In addition, a vaguely nodular lesion, which was composed of plasmacytoid and lymphoid cells, was observed around the abscess. Immunohistochemically, an anti-Treponema pallidum antibody revealed numerous Treponemas around the abscess. In situ hybridization revealed that the plasmacytoid and lymphoid cells were Epstein-Barr encoding region (EBER)-positive; κ-positive cells were significantly more prevalent than λ-positive cells, suggesting light-chain restriction. Postoperatively, parenteral antibiotics were administered for four weeks. The patient has been free of recurrence for two years since the surgery. No association between neurosyphilis and EBV-positive lymphoplasmacytic proliferation has ever been reported. Mass formation in early-stage neurosyphilis is an exceptionally rare event. The present case indicates that in syphilis patients, lymphoproliferative disorders that lead to mass formation may be caused by concomitant EBV reactivation. Furthermore, when treating patients with mass lesions of the central nervous system, it is important to check their medical history and perform laboratory screening for infectious diseases to avoid overlooking syphilis infections.

Neurosyphilis presenting as limbic encephalitis.

A man in his 50s presented with focal seizures and was found to have an inflammatory cerebrospinal fluid (CSF) with bilateral mesiotemporal lobe hyperintensity on magnetic resonance imaging (MRI) of the brain. Corticosteroid treatment was initiated for management of limbic encephalitis. Focal seizures, imaging abnormalities and inflammatory CSF persisted despite treatment and the patient was found to have neurosyphilis after developing neuropsychiatric symptoms. Syphilis is a sexually transmitted bacterial infection with multisystem involvement including neurological and psychiatric manifestations. Case reports have emerged of neurosyphilis presenting as limbic encephalitis with CSF pleocytosis and temporal lobe hyperintensity on MRI of the brain. Persistence of CSF or MRI abnormalities despite immunosuppressive therapy for limbic encephalitis should prompt investigation for alternate causes of chronic meningoencephalitis, which can occasionally include neurosyphilis.

Neurosyphilis presenting with Guillain-Barre syndrome: a case report.

BACKGROUND: Syphilis is associated with a wide variety of systemic presentations, earning it the moniker "The great mimicker". Neurosyphilis is classically associated with meningovasculitis in the acute-subacute stage and tabes dorsalis and dementia paralytica in later stages. However, one of the less well described presentations include Guillain-Barre Syndrome. This case presents a patient with an ascending polyneuropathy suspicious for Guillain-Barre Syndrome who also had other atypical findings including a truncal sensory loss, optic disc swelling, and rash ultimately found to have neurosyphilis. Electrodiagnostic testing was consistent with demyelination, supporting a diagnosis of neurosyphilis associated Guillain-Barre Syndrome. CASE PRESENTATION: A 37-year-old female presented to the emergency department with a weakness and difficulty swallowing. She described a three-month history of symptoms, initially starting with a persistent headache followed by one month of a pruritic rash on her chest, palms, and soles. Two weeks prior to presentation, she developed progressive weakness in her arms, numbness in her arms and chest, and difficulty swallowing. Neurological exam was notable for multiple cranial neuropathies, distal predominant weakness in all extremities, length-dependent sensory loss, and hyporeflexia. Investigation revealed a positive Venereal Disease Research Laboratory in her cerebrospinal fluid without significant pleocytosis, contrast enhancement in cranial nerves V, VII, and VIII on MRI, and a demyelinating polyneuropathy on electrodiagnostic testing. She was diagnosed with Guillain-Barre syndrome, secondary to neurosyphilis. The patient acutely declined and required intubation, and ultimately made a full recovery after treatment with plasmapheresis and penicillin. CONCLUSIONS: This case describes a clinical entity of syphilitic Guillain-Barre Syndrome and highlights the importance of including syphilis in the differential of any patient presenting with ascending polyradiculopathy, especially given the resurgence of syphilis.

A Cluster of Ocular Syphilis Cases with a Common Sex Partner - Southwest Michigan, 2022.

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.

Neurological manifestations of syphilis-HIV coinfection in South Africa.

OBJECTIVE: Syphilis and HIV coinfection is highly prevalent in South Africa, and both can cause neurological complications. We describe the clinical presentation and outcome of neurosyphilis in patients with and without HIV coinfection diagnosed at a tertiary facility, Groote Schuur Hospital (GSH), in South Africa. METHODS: We retrospectively analyzed folders of adults with positive cerebrospinal fluid (CSF) fluorescent treponemal antibody absorption test in 2018 and 2019, with follow-up data collected until 2022. RESULTS: HIV-coinfection was identified in 35% of the 69 included patients. Patients with HIV-coinfection were more likely to be female (58% vs 25% female, p < 0.01), and present earlier (median age = 31 years vs. 40 years, p < 0.001). Neuropsychiatric manifestations (confusion, dementia, psychosis), and strokes were the commonest clinical presentations in both groups. Those with HIV-coinfection were significantly less likely to be diagnosed with neurosyphilis by the treating clinician (71% vs. 91%, p < 0.05), as were those with a negative CSF Venereal Disease Research Laboratory (74% vs. 94%, p < 0.05). Accurate diagnosis of neurosyphilis was associated with an increased 12-month survival (alive: N = 36 [63%]) relative to those who did not receive an accurate diagnosis (alive: N = 2 [17%], p < 0.05). Those who were optimally treated with antibiotics had significantly higher 12-month survival (alive: N = 33, 63%) compared to those with suboptimal treatment (alive: N = 5, 29%), p < 0.01. CONCLUSION: Neurosyphilis presented similarly in those with and without HIV-coinfection. Accurate identification and optimal antibiotic treatment of neurosyphilis, particularly in CSF VDRL negative patients and those with HIV-coinfection, is necessary to improve patient survival.

[Neurosyphilis or not - a case of a differential diagnostic challenge]. / Neurosyphilis vagy nem ­ egy differenciáldiagnosztikai kihívás esete.

We report the case of a 42-year-old woman with paraparesis associated with transverse myelitis. For differential diagnostics detailed microbiological, cerebrospinal fluid (CSF) and neuroimaging examinations were performed. Syphilis was confirmed, but diagnosis of neurosyphilis was only probable based on the CSF microbiological test results. The beneficial treatment response to application of the therapeutic protocol for syphilis supported the supposed diagnosis of syphilis-associated myelitis in our case. In this case report we reviewed the differential diagnostic tools of myelopathies/myelitis.
Nowadays regarding to growing prevalence of syphilis worldwide physicians should face on its presence and medical consequences.

Neurosyphilis in a young man having HIV infection, blurring of vision and skin rash.

We report a 22-year-old homosexual man, a known case of HIV-1 infection but non-compliant to medications, who presented with a 5-month history of progressive painless non-pruritic coin-shaped skin lesions and recent gradual bilateral blurring of vision. His history divulged a primary syphilitic event 1 year prior to the present clinical manifestations. Investigation led to the diagnosis of neurosyphilis with ocular involvement with concurrent signs of secondary syphilis. Treatment with aqueous crystalline penicillin G, ophthalmic steroid and tropicamide drops, and topical emollients resulted in significant clinical improvement of ocular symptoms and skin lesions. The diagnosis of neurosyphilis requires a high degree of clinical suspicion and should be included in the differential diagnosis of unexplained ocular symptoms, particularly in men who have sex with men and HIV-infected patients. This is necessary for the early diagnosis, appropriate management, and good outcome of these patients.

A Rare Case of Blindness Caused by Syphilis with Malignant Hypertensive Nephropathy.

The number of patients with syphilis has been rapidly increasing. Without treatment, syphilis can damage various organs and become life-threatening. We herein report a 29-year-old woman diagnosed with neurosyphilis, acute hydrocephalus, syphilitic uveitis combined with hypertensive retinopathy, and malignant hypertensive nephropathy. To our knowledge, this is the first report of syphilis complicated with malignant hypertensive nephropathy proven by a renal biopsy. Neurosyphilis was successfully treated with intravenous penicillin G, and severe hypertension subsequently resolved. However, delayed medical examinations and complications of syphilitic uveitis and hypertensive retinopathy resulted in irreversible visual loss. To prevent irreversible organ damage, early treatment is essential.

[A case of neurosyphilis presenting as bilateral temporal, cortical and subcortical encephalitis].

A 37-year-old man who had a low grade fever for 5 days admitted to our hospital due to disturbance of consciousness and seizure. Brain MRI showed abnormal hyperintensity in the bilateral temporal lobes, cortical and subcortical lesions on fluid-attenuated inversion recovery image. Treponemal and non-treponemal specific antibodies were positive in serum and cerebrospinal fluid, therefore he was diagnosed as having neurosyphilis. Treatment with intravenous penicillin G and metylpredonisolone improved his clinical symptons, imaging abnormalities and CSF findings. Patients of neurosyphilis with mesiotemporal encephalitis show common features such as young age, HIV-negative, subacute cognitive impairment and seizure, as seen in our case. Early diagnosis of neurosyphilis and appropriate treatment make clinical improvement, however the clinical diagnosis of neurosyphilis is sometime difficult because most patients present with disturbance of consciousness or seizure. The possibility of neurosyphilis should be considered when MRI results indicate temporal abnormalities.

Neurosyphilis among people with and without HIV infection: A Danish nationwide prospective, population-based cohort study 2015-2021.

BACKGROUND: Comparative data on clinical presentation, laboratory characteristics, treatment, and outcome of neurosyphilis (NS) in people living with HIV (PLWH) and NS patients without HIV are scarce. METHODS: Nationwide, population-based, prospective cohort study on all adults with NS diagnosed between 2015 and 2021 at departments of infectious diseases in Denmark. RESULTS: We identified 108 patients with NS, which equals a yearly incidence of 0.3/100,000 adults. The median age was 49 years, 85 (79%) were male, 43 (40%) were men having sex with men and 20 (22%) were PLWH. Ninety-five (88%) had early NS, 37 (34%) had ocular or ocular and otogenic NS, and 27 (25%) had symptomatic meningitis. Most common symptoms were visual disturbance (44%), skin rash (40%), fatigue (26%) and chancre (17%). Median CSF leukocyte count was 27 × 106 cells/L. PLWH less often had neurological deficits (p = 0.02). Unfavorable outcome was observed in 23 (21%) at discharge of whom 0 were PLWH (p = 0.01). Among the 88 NS patients without HIV a CSF leukocyte count of ≥ 30 × 106 cells/L was associated with unfavorable outcome (OR = 3.3 (95% confidence interval: 1.1-10.4)). CONCLUSIONS: PLWH with NS have better outcomes than NS patients without HIV infection.
