Etiological Profile of First Episode Seizures in Paediatric Patients at a Tertiary Care Centre: A Descriptive Cross-sectional Study.

INTRODUCTION: Seizures are the most common neurological emergency and one of the most common reasons for paediatrics hospital admissions. This study aimed to identify the etiology, clinical profile, and immediate outcome of children with the first episode of seizure in Eastern Nepal. METHODS: This was a prospective descriptive study carried out in the Tertiary Care Centre from September 2022 to August 2023. Ethical clearance was taken from the Institutional Review Committee (Ref no:654/2022). Convenience sampling was done to include 170 children presenting with the first episode of seizure at age 6 months to 15 years. Variables collected were demographics, clinical presentations, family history, trauma history, laboratory tests, neuroimaging, EEG, final diagnosis, and immediate outcome. RESULTS: A total of 170 patients were admitted with the first episode of seizure with 123 (72.36%) males and 47 (27.64%) females. The mean age of the patients was 5.13±2.95 years with 104 (61.18%) patients under 5 years of age. The most common seizure was generalized tonic-clonic type in 132 (77.64%) patients. The most common associated symptom was fever in 150 (88.23%) children. Neuroimaging was abnormal in 52 (30.59%) patients, with neurocysticercosis seen in 27 (15.88%). The most common etiology was febrile seizure in 92 (54.17%) patients, neurocysticercosis in 27 (15.88%), and meningitis in 12 (7.05%). CONCLUSIONS: Febrile seizures, neurocysticercosis, infection, and trauma were the major causes of seizures in children. When simple febrile seizures were unlikely, lumbar puncture, neuroimaging, and laboratory tests were useful tools for diagnosing etiologies of seizures.

Refractory singultus and area postrema syndrome as a presentation of neurocysticercosis.

Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system, caused by the pork tapeworm, Taenia solium Common presenting features are seizures, headaches and focal neurodeficits. The present report details the anecdote of a middle-aged Asian man, who presented with subacute onset of persistent nausea, vomiting and hiccups. Following unsuccessful trials with numerous prokinetic, antipsychotic, muscle relaxant and anticonvulsant medications, as well as an uneventful battery of gastrointestinal tests, he was referred for neurological evaluation. The constellation of symptoms was congruent with the diagnosis of area postrema syndrome. Although initial CT scan of brain was normal, MRI with contrast evaluation revealed a circumscribed, ring-enhancing lesion of the dorsal medulla oblongata, reminiscent of colloid vesicular stage of NCC. The patient was successfully treated with steroids and albendazole. The association of refractory singultus, nausea and vomiting and NCC is thus far, not reported in the literature.

Spinal cord compression by cystic IgG4-related spinal pachymeningitis mimicking neurocysticercosis: a case report.

BACKGROUND: To report a case of IgG4-related pachymeningitis presenting with cystic lesions mimicking neurocysticercosis. CASE PRESENTATION: A 40-year-old female patient with tetraparesis, dysphagia and dysphonia was evaluated with clinical examination, magnetic resonance imaging, and meningeal biopsy. Magnetic resonance imaging (MRI) revealed diffuse pachymeningeal enhancement involving the cranial, cervical, thoracic, and lumbar segments with spinal cord compression and cystic lesions. CSF immunology was initially positive for cysticercus cellulosae. After disease progression a meningeal biopsy was compatible with IgG4 related disease. The patient had partial response to rituximab and needed multiple surgical procedures for spinal cord decompression and CSF shunting. CONCLUSIONS: This case highlights the possibility of IgG4-related disease in patients with diffuse pachymeningitis causing spinal cord compression, even with cystic lesions on MRI. Diagnosis of IgG4-related pachymeningitis is paramount due to the possibility of treatment response to immunotherapy, particularly to anti-CD20 agents.

Concordance between a New Rapid Point-Of-Care Assay and Standard ELISA in the Detection of Cysticercosis Antigens in Urine.

Neurocysticercosis is a parasitic disease of major public health importance. Definitive diagnosis requires neuroimaging, which is typically unavailable in rural impoverished regions of endemicity. Screening immunoassays can support diagnosis in this setting by identifying individuals most likely to have severe forms of disease for referral to imaging. Urine sampling is convenient, painless, and generally well accepted. We developed a rapid point-of-care (POC) assay to detect urinary antigens and assessed concordance with a standard antigen ELISA (Ag-ELISA), both using monoclonal antibodies TsW8/TsW5. From 28,145 stored community samples with Ag-ELISA results, we selected 843 for comparison, 281 each from nonreactive (ratio <1), reactive-below-cutoff (ratio 1:3), and positive (ratio ≥3) samples. Overall agreement was 73.6%, with strong agreement observed in the nonreactive (280/281, 99.6%) and positive (255/281, 90.8%) groups. This affordable noninvasive POC test can be applied to identify individuals in the community most at risk of developing severe disease.

Current challenges in neurocysticercosis: recent data and where we are heading.

PURPOSE OF REVIEW: Neurocysticercosis (NCC) is still a significant contributor to neurological disease in vast regions of the world, and increasingly diagnosed in nonendemic countries because of travel and immigration from endemic settings. There is a need for clinicians in endemic and nonendemic regions to understand the complexities of its diagnosis and management. RECENT FINDINGS: Recent information on the performance and use of available imaging and immunodiagnostic tools as well as antiparasitic and anti-inflammatory therapeutic regimes were assessed. SUMMARY: Imaging and serology data should be assessed in the context of the specific type of NCC to improve diagnostic precision. In terms of therapeutic approaches, more controlled data is required on the efficacy and safety of combined antiparasitic therapy, and antiseizure and anti-inflammatory regimes should be optimized to minimize perilesional damage and reduce the risk of epilepsy.

Production and evaluation of a new set of recombinant antigens for the serological diagnosis of human cysticercosis.

Human cysticercosis caused by Taenia soliun (T. soliun) is endemic in certain areas of Latin America, Asia and Sub-Saharan Africa. Neurocysticercosis (NCC) is mainly diagnosed by neuroimaging, which, in most cases, is unavailable in endemic areas. Due to their high sensitivity and specificity, serological tests such as enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) based on the glycosylated fraction of the cyst CS50 are widely used for the detection of the anti-cysticercus IgG antibodies despite their significant cost and the need of cysticercus material. Given their cost-effectivess and simplicity, immunoassays based on recombinant proteins could provide new alternatives for human cysticercosis diagnosis: such tests would be aimed at screening those people living in remote areas who need further examination. To date, however, no test using recombinant antigens is commercially available. Herein, five recombinant proteins (R14, R18, R93.1, R914.1, and R915.2) were produced, three of which (R93.1, R914.1, and R915.2) were newly identified from the cyst fluid. Evaluation of the diagnostic performance of these recombinant antigens by ELISA was done using sera from 200 epileptic and non-epileptic individuals in comparison with the WB-CS50 as the reference serological method. Recombinant proteins-based ELISA showed a level of diagnostic performance that is inferior than the reference serological method, but similar to that of the native antigen ELISA for human cysticercosis (commonly used for screening). Further optimization of expression conditions is still needed in order to improve proteins solubility and enhance diagnostic performance for human cysticercosis detection. However, this preliminary evaluation of the recombinant antigens has shown their potential valuable use for screening cysticercosis in patients with epilepsy attending dispensaries in remote areas. Future studies should be conducted to evaluate our recombinant antigens in a large group of patients with different stages of NCC, and in correlation with imaging findings.

Atypical Presentation of Foster Kennedy Syndrome due to Neurocysticercosis: A Rare Case Report.

This case highlights the atypical presentation of Foster-Kennedy syndrome (FKS) associated with Neurocysticercosis (NCC), a prevalent cause of space-occupying lesions in areas endemic to the parasite. We report a newly diagnosed case of NCC in a 13-year-old boy who presented with a one-day history of abnormal movements of the left side of the body and no ocular complaints. Fundus examination of the patient revealed temporal disc pallor and a cup disc ratio (CDR) of 0.6 in the right eye suggesting unilateral optic disc atrophy and a hyperaemic disc with CDR 0.3 and blood vessel tortuosity in the left eye suggesting contralateral impending disc edema, mimicking the classic triad of FKS. He was diagnosed with NCC based on clinical features and radiological findings and was started on Carbamazepine (400 mg), Prednisolone (60 mg), Albendazole (400 mg), Acetazolamide (750 mg), and Vitamin B12 complex.

Neurocysticercosis Prevalence and Characteristics in Communities of Sinda District in Zambia: A Cross-Sectional Study.

BACKGROUND: This study aimed at describing the epidemiology of (neuro)cysticercosis as well as its clinical and radiological characteristics in a Taenia solium endemic district of Zambia. METHODS: This was part of a cross-sectional community-based study conducted in Sinda district to evaluate an antibody-detecting T. solium point-of-care (TS POC) test for taeniosis and (neuro)cysticercosis. All TS POC cysticercosis positive (CC+) participants and a subset of the TS POC cysticercosis negative (CC-) received a clinical evaluation and cerebral computed tomography (CT) examination for neurocysticercosis (NCC) diagnosis and staging. RESULTS: Of the 1249 participants with a valid TS POC test result, 177 (14%) were TS POC CC+ . Cysticercosis sero-prevalence was estimated to be 20.1% (95% confidence intervals [CI] 14.6-27.0%). In total, 233 participants received a CT examination (151 TS POC CC+ , 82 TS POC CC-). Typical NCC lesions were present in 35/151 (23%) TS POC CC+ , and in 10/82 (12%) TS POC CC- participants. NCC prevalence was 13.5% (95% CI 8.4-21.1%) in the study population and 38.0% (95% CI 5.2-87.4%) among people reporting epileptic seizures. Participants with NCC were more likely to experience epileptic seizures (OR = 3.98, 95% CI 1.34-11.78, p = 0.01) than those without NCC, although only 7/45 (16%) people with NCC ever experienced epileptic seizures. The number of lesions did not differ by TS POC CC status (median: 3 [IQR 1-6] versus 2.5 [IQR 1-5.3], p = 0.64). Eight (23%) of the 35 TS POC CC+ participants with NCC had active stage lesions; in contrast none of the TS POC CC- participants was diagnosed with active NCC. CONCLUSION: NCC is common in communities in the Eastern province of Zambia, but a large proportion of people remain asymptomatic.

Characterization of antigenic proteins of the Taenia solium postoncospheral form.

Neurocysticercosis is the leading cause for acquired epilepsy worldwide, and it is caused by the larval stage of the parasite Taenia solium. Several proteins of this stage have been characterized and studied to understand the parasite-host interaction, however, the proteins from the early cysticercus stages (the postoncospheral form) have not yet been characterized. The study of the postoncospheral form proteins is important to understand the host-parasite relationship in the early stages of infection. The aim of this work was to identify postoncospheral form antigenic proteins using sera from neurocysticercosis patients. T. solium activated oncospheres were cultured in HCT-8 cells to obtain the postoncospheral form. Soluble total and excretory/secretory proteins were obtained from the postoncospheral form and were incubated with both pool sera and individual serum of neurocysticercosis positive human patients. Immunoblotting showed target antigenic proteins with apparent molecular weights of 23 kDa and 46-48 kDa. The 46-48 kDa antigen bands present in soluble total and excretory/secretory postoncospheral form proteins were analyzed by LC-MS/MS; proteins identified were: nuclear elongation factor 1 alpha, enolase, unnamed protein product/antigen diagnostic GP50, calcium binding protein calreticulin precursor and annexin. The postoncospheral form expresses proteins related to interaction with the host, some of these proteins are predicted to be exosomal proteins. In conclusion, postoncospheral proteins are consistent targets of the humoral immune response in human and may serve as targets for diagnosis and vaccines.

Circulating cell-free DNA as a biomarker for molecular diagnosis of Neurocysticercosis.

Taenia solium is a widespread zoonotic tapeworm that predominantly affects regions of Latin America, South and South-East Asia, and Sub-Saharan Africa. Neurocysticercosis (NCC), the presence of T. solium cysts in the brain is associated with diverse clinical manifestations, such as epilepsy, seizures, and neurological deficits. It is a significant cause of preventable epilepsy globally, accounting for approximately 30% of cases in endemic regions. The diagnosis of neurocysticercosis relies on neuroimaging techniques, but these resources are often limited in low-income countries, resulting in an underestimation of the disease burden. The present study enrolled 141 patients who were clinically suspected and radiologically confirmed for NCC at the Neurology OPD of PGIMER, Chandigarh. Additionally, 98 control subjects attending the PGIMER OPD for investigation were also included. Plasma and urine samples were collected from all participants for further analysis. Cell-free DNA extraction was performed using specific kits, and the quality of the extracted DNA was assessed. The RT-LAMP assay targeted the cox1 gene. Real-time RT-LAMP results were evaluated using a fluorescence graph obtained with the Genei III fluorimeter. Among a group of patients diagnosed with NCC, the gene was identified in 74.4% of plasma samples and 67.3% of urine samples. In comparison, the T. solium cox1 gene was found in 6.1% of control subjects in plasma and urine samples using the LAMP assay. In conclusion, the study emphasises the need for improved diagnostic methods for NCC and presents promising alternatives, such as RT-LAMP and urine-based cell-free DNA analysis. These approaches offer advantages in terms of cost-effectiveness, simplicity, and diagnostic accuracy.

Calcified cerebral toxoplasmosis associated with recurrent perilesional edema causing neurological manifestations in an HIV-infected individual: case report with a decade-long follow-up.

Four cases of people living with HIV/AIDS (PLWHA) with calcified cerebral toxoplasmosis associated with perilesional edema causing a single episode of neurological manifestations have recently been reported. Here, we describe the first detailed description of perilesional edema associated with calcified cerebral toxoplasmosis causing three episodes of neurological manifestations in a PLWHA, including seizures in two of them. These recurrences occurred over approximately a decade. Throughout this period, the patient showed immunological and virological control of the HIV infection, while using antiretroviral therapy regularly. This case broadens the spectrum of an emerging presentation of calcified cerebral toxoplasmosis, mimicking a well-described finding of neurocysticercosis in immunocompetent hosts.

Silent Intruder: Unusual Presentation of Neurocysticercosis in an HIV-Infected Patient from the Far Northern Brazilian Amazon.

Neurocysticercosis, a parasitic infection of the central nervous system (CNS), is a significant public health issue globally, including in Brazil. This article presents a case report of a 44-year-old male patient residing in the rural area of Roraima, the northernmost region of Brazil within the Amazon Forest. The patient, with chronic HIV infection, acquired the Taenia solium helminth, resulting in neurocysticercosis development. Remarkably, the diagnosis of neurocysticercosis was not initially apparent but emerged through meticulous analysis following a motorcycle accident. The absence of seizures, a common clinical manifestation, complicated the diagnostic process, making it an uncommon case of NCC, which may be related to co-infection. As the patient's condition progressed, multiple complications arose, requiring additional medical attention and interventions. This case underscores the immense challenges faced by healthcare teams in managing neurocysticercosis effectively. It emphasizes the critical need for a comprehensive, multidisciplinary approach to provide optimal care for such complex cases. The study's findings underscore the importance of raising awareness and implementing improved strategies for tackling neurocysticercosis, particularly in regions where it remains a prevalent concern.

Neurocysticercosis Presenting as Migraine in the United States.

BACKGROUND Cysticercosis is a condition caused by infection with the larval form of Taenia solium, a pork tapeworm that uses pigs as an intermediate host. Humans become infected when they ingest water or food contaminated with tapeworm cysts. Cysticercosis is increasing in frequency in developed countries due to increased access to travel. Neurocysticercosis occurs when Taenia solium cysts embed within the nervous system. The clinical presentation of neurocysticercosis ranges from asymptomatic to life-threatening, largely depending on the brain parenchymal involvement. The diagnosis is typically made with a combination of clinical evaluation, serology, and neuroimaging. Treatment for parenchymal neurocysticercosis may involve anthelmintic agents, symptomatic agents, surgery, or a combination of methods. CASE REPORT A 52-year-old man with a medical history of migraine headaches, complicated type 2 diabetes mellitus, and obesity presented with a 4-month change in his migraines becoming severe, worse over his occiput bilaterally, and unresponsive to abortive therapy. His exposure history was unremarkable except for a habit of eating undercooked bacon, by which he would have developed neurocysticercosis via autoinfection. Neuroimaging and serology confirmed a diagnosis of neurocysticercosis and he was treated accordingly with antiparasitic and anti-inflammatory medications. CONCLUSIONS This presentation is nonspecific and can easily be overlooked, especially if there is an underlying known neurological condition such as migraine. This case illustrates that neurocysticercosis should be considered when an existing neuropathological condition displays a change in presentation or requires a change in therapeutic management, even without obvious risk factors.

INTRODUCTION Neurocysticercosis (NCC), a possible cause of epilepsy with limited epidemiological data in the Dominican Republic, is endemic in four provinces in the country’s south-western region. This study aimed to determine the association between NCC and epilepsy among people living in these endemic regions, and to obtain preliminary data on the prevalence of NCC in these provinces. PATIENTS AND METHODS A case-control design was used, consisting of 111 patients with epilepsy with unknown causes, and 60 controls without epilepsy or NCC. The diagnosis of NCC was based on computed tomography and magnetic resonance imaging of the skull, as well as Western immunoblotting for serum antibodies using Taenia solium, following the criteria of Del Brutto et al. RESULTS NCC was found in 27% of the epileptic patients (n = 30/111) and in 5% of the controls (n = 3/60); the probability of the epileptic patients having NCC was seven times higher than the controls (odds ratio = 7.04, 95% confidence interval: 2.04-24.18; p < 0.001). The participants’ sociodemographic characteristics, including their age, sex, level of education, occupation, and province of residence presented no statistical significance in terms of their association with NCC. CONCLUSIONS This study suggests that NCC is strongly associated with epilepsy in the south-western region of the Dominican Republic, and highlights the need for public health measures to improve the prevention, diagnosis and treatment of both diseases.

Massive neurocysticercosis in a ten-year-old girl: a case report.

BACKGROUND: Massive neurocysticercosis is a rare form of neurocysticercosis, and can lead to serious conditions and even death. CASE PRESENTATION: Here we present a case of ten-year-old Tibetan girl who developed headache and vomiting. Her brain magnetic resonance imaging (MRI) illustrated lots of intracranial cystic lesions, and no obvious extracranial lesions were found. Serum immunoglobulin G antibodies against cysticerci were positive by the use of an enzyme-linked immunosorbent assay (ELISA). These results in combination with her medical history were in line with massive neurocysticercosis. The patients recovered well after supportive management and antiparasitic treatment. CONCLUSIONS: This case provides insights on the diagnosis and treatment of massive neurocysticercosis. The treatment of patients with massive neurocysticercosis should be in an individualized fashion, and the use of antiparasitic drugs in these patients must be decided after carefully weighing the risks and benefits.

Evaluation of a point-of-care test for the diagnosis of Taenia solium neurocysticercosis in rural southern Tanzania: a diagnostic accuracy study.

BACKGROUND: Neurocysticercosis is a common cause of epilepsy in Taenia solium-endemic areas in sub-Saharan Africa but is often undiagnosed because of an absence of affordable diagnostic tools. This study evaluated the diagnostic accuracy of a T solium cysticercosis antibody-detecting lateral-flow point-of-care assay (TS POC test) for the neuroimaging-based diagnosis of neurocysticercosis. METHODS: Patients with epileptic seizures or severe progressive headache were recruited consecutively from three hospitals in southern Tanzania. All patients were tested with the TS POC test. All patients positive for cysticercosis on the TS POC test and every tenth patient who was negative for cysticercosis received a brain CT examination and underwent reference testing for T solium cysticercosis (ie, rT24H-EITB, LLGP-EITB, and antigen ELISA). The primary outcome of the study was the sensitivity of the TS POC test for the diagnosis of neurocysticercosis. FINDINGS: Of the 601 recruited participants, 102 (17%) tested positive for cysticercosis with the TS POC test. Overall, 48 (62%) of the 77 patients positive for cysticercosis and five (17%) of the 29 patients negative for cysticercosis on the TS POC test had CT-confirmed neurocysticercosis. The TS POC test yielded a sensitivity of 49% (uncertainty interval [UI] 41-58) for neurocysticercosis. Sensitivity was similar to that of the rT24H-EITB (44%, UI 37-51) and the antigen ELISA (50%, 43-56). For the subset of neurocysticercosis cases with at least one active (ie, vesicular) lesion, sensitivity was above 98% for the TS POC test, the rT24H-ETIB, and the antigen ELISA. INTERPRETATION: The TS POC test showed promising results for the diagnosis of neurocysticercosis in patients with vesicular lesions, which need to be confirmed in a larger study. This test could be considered to support policies on screening patients with suspected neurocysticercosis in clinical settings, which would allow appropriate referral for neuroimaging and early treatment.
