Neurosyphilis Presenting as Syndrome of Limbic Encephalitis Mimicking Herpes Simplex Virus Neuro-Infection Diagnosed Using CXCL13 Point-of-Care Assay—Case Report. Brain Sci 2023; 13:brainsci13030503. [PMID: 36979313 PMCID: PMC10046340 DOI: 10.3390/brainsci13030503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 03/14/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023] Open
Abstract
The syndrome of limbic encephalitis is a severe clinical condition with heterogenous aetiopathogenesis. A common pathogen causing the infectious syndrome of limbic encephalitis is herpes simplex virus (HSV), but rare cases caused by Treponema pallidum have also been reported. We present the case of a 46-year-old man who presented with sudden onset of headaches, nausea, vomiting, and short-term loss of consciousness with clonic convulsions and subsequent disorientation and aphasia. Examination of the cerebrospinal fluid (CSF) revealed lymphocytic pleocytosis and magnetic resonance of the brain revealed bilateral temporal lesions. Clinical, radiologic, and biochemical examinations of CSF suggested encephalitis caused by HSV. However, the positivity of CXCL-13 chemokine in the CSF by a rapid point-of-care assay suggested active spirochetal infection and led to further serologic investigation. The definitive diagnosis of neuro-syphilis was concluded by positive intrathecal synthesis of immunoglobulins against Treponema pallidum. Penicillin therapy led to a rapid improvement, and the patient was discharged home after three weeks. Due to memory problems and irritability, after eighteen months, he came for a follow-up neurological and psychological examination. The psychological examination revealed a significant deficit in executive functions and behavioural changes. Neurosyphilis should be considered in the differential diagnosis of limbic encephalitis with lymphocytic pleocytosis in cerebrospinal fluid, and CXCL-13 may help to achieve diagnosis.

Abstract
A 52-year-old male was carried to hospital by ambulance, because of an abrupt abnormal behavior and impaired consciousness. Soon after the arrival, the patient started a generalized seizure. Although the seizure was stopped by Midazolam, amnesia were observed. With meningeal irritation signs, in addition to the clinical course, the patient was thought to develop limbic encephalitis. The cause of the encephalitis was diagnosed as neurosyphilis because of the positive serum and CSF syphilis reactions, and the patient was treated with penicillin G from the first admission day on. Steroid pulse therapy was also conducted, followed by acyclovir since herpes encephalitis could not be ruled out; the brain MRI showed left-side dominant T2/FLAIR high intensity lesions in the bilateral temporal lobes and left hippocampus. With the treatment progression, the amnestic syndrome improved and the patient returned to work. Although neurosyphilis is a rare cause of acute onset limbic encephalitis, it is important to keep the possibility of this disease in mind in making a treatment plan.

Abstract
We present the case of a man exhibiting a clinical phenotype of behavioral variant of frontotemporal dementia (bvFTD). The man had developed psychiatric disturbances with verbal aggressiveness over a few months, followed by cognitive and frontal behavioral disorders, fulfilling the clinical criteria for bvFTD. Atrophy and hypometabolism in frontotemporal regions were consistent with the diagnosis. However, serum-screening exams for syphilis infection were positive, and CSF analysis, despite a negative Venereal Disease Research Laboratory Test, suggested the diagnosis of neurosyphilis. After specific antibiotic therapy, the man's behavioral abnormalities and cognitive deficits notably improved, confirming neurosyphilis as the cause of the clinical phenotype. The cognitive deficits completely recovered 1 year post therapy and remained stable for 2 years. After ∼2½ years from the first treatment, the man's behavioral disorders mildly worsened, at which time we re-evaluated him. His cognition was stable, and a positive Venereal Disease Research Laboratory Test confirmed the diagnosis of neurosyphilis. With this case, we demonstrated that in some instances, neurosyphilis can mimic frontotemporal dementia. As a cause of treatable dementia, it should be considered in the differential diagnosis of bvFTD, particularly when psychiatric symptoms and a rapid cognitive decline are noted, even in the presence of brain atrophy and/or hypometabolism.

Abstract
Neurosyphilis is a rare but life-threatening complication of syphilis that can develop even decades after the primary infection and can be unrecognized. Seizures and status epilepticus (SE) may represent the first manifestation in a previously undiagnosed syphilitic patient. We present an exemplification case of a new onset refractory status epilepticus caused by neurosyphilis and we reviewed the existing literature. We selected all studies reporting cases of SE in the context both of patients with a known diagnosis of syphilis and as the first manifestation of neurosyphilis. We identified 50 patients, mostly composed of immunocompetent, middle-aged males. Thirty-nine patients (83%) presented a new onset SE. A history of subtle and rapidly progressive mood and/or cognitive impairment suggesting a limbic encephalitis-like presentation was frequently observed. Focal frontal or temporal SE was reported in 26. Brain MRI frequently showed T2/FLAIR hyperintensities widely involving the medial temporal structures and the frontal lobes. This review should increase the clinician’s awareness of neurosyphilis as a possible etiology of a new onset SE of unknown etiology, especially in the context of a “limbic encephalitis”-like clinical presentation. Prompt recognition and treatment for neurosyphilis partially or completely reverse neurologic sequelae, changing the natural history of the disease.

Abstract
BACKGROUND Epileptic seizures were noted as one of the most overlooked manifestations in syphilis; therefore a few clinicians are concerned about the relationship between epilepsy and syphilis. Our study sought to clarify the prevalence and clinical features of epileptic seizures in patients with syphilis. METHODS We retrieved relevant articles from different databases, using the keywords "syphilis and epilepsy" and then performed statistical analysis to characterize the relationship between these diseases. RESULTS Forty one articles were included in this study: eight described the prevalence of syphilis and epilepsy and the remaining 33 were case reports on syphilis with epileptic seizures. The meta-analysis included 1252 patients with syphilis. The pooled estimate of proportion of prevalence (95% confidence interval) was 0.1384 (0.0955-0.2005), and the proportion and heterogeneity showed different degrees of change among three subgroups. The systematic review included 46 cases of syphilis with epileptic seizures. Thirty two (80%) patients had motor seizures, among whom 20 (62.5%) had tonic-clonic seizures. In addition, 30 (75%) patients had impaired awareness and 18 (45%) had status seizures. Twenty five (62.5%) patients were 35-55 years of age, and 77.5% of the included patients were men. Thirty seven (97.4%) patients were seizure-free after anti-syphilis treatment. LIMITATIONS Research in this field has been conducted for a relatively short period and publication bias may exist. Furthermore, some patients with syphilis and epileptic seizures may not have received a clear diagnosis. CONCLUSION The proportion of prevalence was 0.1384. Most of the included patients were 35-55 years of age and had impaired awareness and motor seizures. Many patients with syphilis and epileptic seizure showed full recovery or the development of minor neurological sequelae, and nearly all patients were seizure-free after timely anti-syphilis treatment.

Neurosyphilis in Africa: A systematic review. PLoS Negl Trop Dis 2017; 11:e0005880.

Abstract
Introduction Neurological involvement is one of the most important clinical manifestations of syphilis and neurological disease occurs in both early and late syphilis. The impact of HIV co-infection on clinical neurosyphilis remains unclear. The highest prevalence of both syphilis and HIV is in Africa. Therefore it might be expected that neurosyphilis would be an important and not uncommon manifestation of syphilis in Africa and frequently occur in association with HIV co-infection; yet few data are available on neurosyphilis in Africa. The aim of this study is to review data on neurosyphilis in Africa since the onset of the HIV epidemic. Methods We searched the literature for references on neurosyphilis in Africa for studies published between the 1st of January 1990 and 15th February 2017. We included case reports, case series, and retrospective and prospective cohort and case-control studies. We did not limit inclusion based on the diagnostic criteria used for neurosyphilis. For retrospective and prospective cohorts, we calculated the proportion of study participants who were diagnosed with neurosyphilis according to the individual study criteria. Depending on the study, we assessed the proportion of patients with syphilis found to have neurosyphilis, and the proportion of patients with neurological syndromes who had neurosyphilis. Due to heterogeneity of data no formal pooling of the data or meta-analysis was undertaken. Results Amongst patients presenting with a neurological syndrome, three studies of patients with meningitis were identified; neurosyphilis was consistently reported to cause approximately 3% of all cases. Three studies on stroke reported mixed findings but were limited due to the small number of patients undergoing CSF examination, whilst neurosyphilis continued to be reported as a common cause of dementia in studies from North Africa. Ten studies reported on cases of neurosyphilis amongst patients known to have syphilis. Studies from both North and Southern Africa continue to report cases of late stage syphilis, including tabes dorsalis and neurosyphilis, in association with ocular disease. Discussion This is the first systematic review of the literature on neurosyphilis in Africa since the beginning of the HIV epidemic. Neurosyphilis continues to be reported as a manifestation of both early and late syphilis, but the methodological quality of the majority of the included studies was poor. Future well-designed prospective studies are needed to better delineate the incidence and clinical spectrum of neurosyphilis in Africa and to better define interactions with HIV in this setting. Involvement of the central nervous system is an important manifestation of syphilis which may be more common in patients co-infected with HIV. As most cases of syphilis and HIV are seen in Africa it might be anticipated that neurosyphilis was common there. We reviewed all published material on neurosyphilis in Africa since 1990. There were few well designed studies of neurosyphilis. A small number of studies suggested that syphilis remains a cause of meningitis in Africa. Our data suggest that neuosyphilis remains an important disease in Africa but better prospective studies are needed to understand its epidemiology.

Abstract
Although neurosyphilis (NS) keeps plaguing worldwide, often with oligosymptomatic and atypical manifestations, the most recent reports fail to provide useful information, like details of the clinical history and even of the previous early therapy. We conducted a survey of the literature of the last 5 years on the clinical presentation of NS, recording the aforementioned inaccuracies. One hundred and thirty-seven articles were collected, reporting on 286 patients. General paresis was the commonest form (49%), often manifesting with cognitive impairment and psychiatric symptoms. Syphilitic meningitis was found in 63 patients (22%), mainly with ocular or auditory involvement. Meningovascular and tabetic form were both found in 12% of cases. Gummatous and epileptic manifestations were rare. Perusal of the literature confirms that NS prevalence is increasing, often with manifestations that are atypical for timing and type of lesions. Unfortunately, many articles are lacking of critical information, like an accurate clinical history and timing of the therapy making difficult to assess the effectiveness of penicillin in preventing NS.

Abstract
BACKGROUND It was observed that a good number of patients presenting with psychiatric manifestations when investigated later because of unresponsiveness to treatment or late development of organic features turned out to be treatable limbic syndromes. INTRODUCTION The aim of this study is to assess the patients presenting with new onset neuropsychiatric symptoms satisfying the criteria for probable limbic encephalitis. PATIENTS AND METHODS Patients referred to neurology department following a period of treatment for neuropsychiatric symptoms, which did not respond to conventional treatment were analyzed using Electroencephalography (EEG), magnetic resonance imaging, cerebrospinal fluid, screening for malignancy Vasculitic work-up, histopathology and autoantibody done when feasible. RESULTS There were 22 patients satisfying criteria for probable limbic encephalitis. Their mean age was 34.5 years. Symptoms varied from unexplained anxiety, panic and depression, lack of inhibition, wandering, incontinence, myoclonus, seizures and stroke like episodes. Three had systemic malignancy, 10 had chronic infection, one each with vasculitis, acute disseminated encephalomyelitis, Hashimoto encephalitis and two each with non-convulsive status, cryptogenic and Idiopathic inflammation. CONCLUSION All patients who present with new onset neuropsychiatric symptoms need to be evaluated for sub-acute infections, inflammation, autoimmune limbic encephalitis and paraneoplastic syndrome. A repeated 20 minute EEG is a very effective screening tool to detect organicity.
