Central expression and peripheral levels of MMP-9 and TIMP-1 in patients with temporal lobe epilepsy.

Purpose: Thirty percent of epilepsy patients are drug-resistant (DR) and, in adults, temporal lobe epilepsy (TLE) is the most common form of DR- epilepsy. Patients with TLE exhibit a neuroinflammatory response associated with blood-brain barrier dysfunction. In this context, the main aim of our study was to evaluate peripheral levels and central expression of MMP-9 and TIMP-1 in TLE patients and assess their association with drug resistance and inflammatory markers.

The performance of a point-of-care test for the diagnosis of Neurocysticercosis in a resource-poor community setting in Zambia - a diagnostic accuracy study.

Background: Neurocysticercosis (NCC) is the main cause of epilepsy in endemic rural communities. NCC diagnosis is difficult due to unavailability and unaffordability of serologic assays and neuroimaging. This study aimed to assess the performance of a cheap, novel lateral-flow point-of-care (TS POC) test for the diagnosis of NCC in a community setting.

Disseminated Intracranial and Spinal Neurenteric Cysts: A Case Report and Literature Review.

Neurenteric cysts (NECs) are rare congenital, benign lesions of the central nervous system (CNS), predominantly located within the spinal cord. However, they may also occur less frequently within the brainstem, fourth ventricle, or cerebellopontine angle (CPA). Originating from anomalous interactions between embryonic layers, NECs are recognized for their potential to compress adjacent structures.

Oxidative Stress in the Murine Model of Extraparenchymal Neurocysticercosis.

Oxidative stress is associated with several infectious diseases, as well as the severity of inflammatory reactions. The control of inflammation during parasite destruction is a target of neurocysticercosis treatment, as inflammation is strongly related to symptom severity. In this study, we investigated the presence of malondialdehyde and protein carbonyl, two by-products of reactive oxygen species (ROS), in an experimental model of extraparenchymal neurocysticercosis.

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.

Current Role of Surgery in the Treatment of Neurocysticercosis.

Neurocysticercosis (NCC) is a common parasitic disease of the central nervous system (CNS) in low- and middle-income countries. The infection is pleomorphic, caused by the larval form of the cestode, , and part of the heterogeneity of its clinical presentations is associated with the localization of the parasite within the CNS. Changes in the current epidemiological trends of NCC indicate that extra-parenchymal NCC is proportionally becoming more frequent.

Causes and prognosis of adults experiencing a first seizure in adulthood: A pilot cohort study conducted in five countries in Latin America.

There are limited data on first seizure (FS) among adults in low and middle-income countries. We describe findings from a prospective cohort study involving 180 adults presenting with seizures in emergency departments in five Latin American countries. Overall, 102 participants (56.

Neurocysticercosis: The duration of its preclinical phase relies on the parasite location.

Objectives: Neurocysticercosis (NC) is a heterogeneous disease particularly in terms of response to treatment and prognosis. Parasite localization is one of the main factors involved in this heterogeneity. In this study we aim to determine whether differences in the duration of the preclinical phase associated with parasite location, could contribute to said heterogeneity.

Epidemiology of swine cysticercosis in two rural communities of Zacapa, Guatemala.

Taeniasis/cysticercosis complex caused by Taenia solium, is a serious public health problem and causes major economic losses to swine producers in developing countries in Asia, Africa and the Americas. Despite scarce epidemiological data, Guatemala is considered endemic for T. solium.

Can sPD-1 and sPD-L1 Plasma Concentrations Predict Treatment Response among Patients with Extraparenchymal Neurocysticercosis?

Extraparenchymal neurocysticercosis (EP-NC) is a chronic, potentially life-threatening disease that responds poorly to initial anthelmintic drug therapy. A depressed specific reactivity of peripheral lymphocytes and an increased level of specific Tregs accompanies EP-NC. The immune checkpoint pathway PD-1 and its ligand PD-L1 downregulates effector T cells, causing specific immune suppression in chronic diseases.

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.

Sexual dimorphism in the murine model of extraparenchymal neurocysticercosis.

Neurocysticercosis is a heterogeneous disease, and the patient's sex seems to play a role in this heterogeneity. Hosts' sexual dimorphism in cysticercosis has been largely explored in the murine model of intraperitoneal Taenia crassiceps cysticercosis. In this study, we investigated the sexual dimorphism of inflammatory responses in a rat model of extraparenchymal neurocysticercosis caused by T.

Low responsiveness of peripheral lymphocytes in extraparenchymal neurocysticercosis.

Background: The morbidity and mortality of extraparenchymal neurocysticercosis (EP-NC) remain high and effectiveness of current medical treatment is suboptimal. Various factors have been implicated in the severity of EP-NC and in the poor response to treatment, but the possible role of host immune and endocrine systems has not yet been examined thoroughly.

Methodology/principal Findings: 42 participants with EP-NC before receiving standard treatment and 25 healthy controls were included in the study.

Neurocysticercosis and hydrocephalus: the value of ventriculoperitoneal shunting in its management.

Background: Hydrocephalus is the main complication of extraparenchymal neurocysticercosis (EP-NC). Its symptomatic management relies mainly on the placement of a ventriculoperitoneal shunt (VPS). Previous studies have shown that this surgical procedure is associated with a poor prognosis, but current information is lacking.

Consensus Competencies for Postgraduate Fellowship Training in Global Neurology.

Background And Objectives: Use a modified Delphi approach to develop competencies for neurologists completing ≥1 year of advanced global neurology training.

Methods: An expert panel of 19 United States-based neurologists involved in global health was recruited from the American Academy of Neurology Global Health Section and the American Neurological Association International Outreach Committee. An extensive list of global health competencies was generated from review of global health curricula and adapted for global neurology training.

Pharmacokinetic Study of Intranasal Dexamethasone and Methylprednisolone Compared with Intravenous Administration: Two Open-Label, Single-Dose, Two-Period, Two-Sequence, Cross-Over Study in Healthy Volunteers.

Dexamethasone (DXM) and methylprednisolone (MEP) are potent glucocorticoids used to control several inflammatory conditions. Evidence of delayed DXM reaching the central nervous system (CNS) as well as tachyphylaxis and systemic, undesirable side effects are the main limitations of peripheral delivery. Intranasal administration offers direct access to the brain as it bypasses the blood-brain barrier.

Neurocysticercosis: A Review into Treatment Options, Indications, and Their Efficacy.

Neurocysticercosis, due to the localization of larvae in the Central Nervous System, is a neglected tropical disease still endemic in much of Latin America, Asia and sub-Saharan Africa. The therapeutic management of NC has gradually improved with the establishment of neuroimaging studies (CT and MRI) in endemic countries and with the demonstration of the efficacy of albendazole and praziquantel in the 1980s. But the morbidity and mortality of this preventable disease remain an unacceptable fact.

Neurocysticercosis in Latin America: Current epidemiological situation based on official statistics from four countries.

Background: Neurocysticercosis (NC) is one of the major parasitic diseases affecting the central nervous system and is endemic in much of Asia, sub-Saharan Africa, and Latin America. Its epidemiology is difficult to assess, although official registries are available in Brazil, Colombia, Ecuador, and Mexico.

Methodology/principal Findings: Using official statistics, we assessed trends in NC hospitalization rates during 1998-2019 in Brazil and Ecuador, during 2004-2019 in Mexico, and during 2009-2019 in Colombia.

taeniasis/cysticercosis in Guatemala: a prevalent public health problem?

In Guatemala, neurocysticercosis (NCC) was first recognized in 1940; since then, cases of NCC have been reported in all Guatemalan departments. However, epidemiological studies on infections are scarce and most information remains unpublished. This study aims to provide evidence of infections as a public health problem in Guatemala.

Multiple-bead assay for the differential serodiagnosis of neglected human cestodiases: Neurocysticercosis and cystic echinococcosis.

Background: Neurocysticercosis (NCC), and cystic echinococcosis (CE) are two neglected diseases caused by cestodes, co-endemic in many areas of the world. Imaging studies and serological tests are used in the diagnosis of both parasitic diseases, but cross-reactions may confound the results of the latter. The novel multiplex bead-based assay with recombinant antigens has been reported to increases the diagnostic accuracy of serological techniques.

Evaluation of recombinant glutathione transferase 26 kDa, thioredoxin-1, and endophilin B1 of Taenia solium in the diagnosis of human neurocysticercosis.

Neurocysticercosis caused by Taenia solium larvae is a neglected disease that persists in several countries, including Mexico, and causes a high disability-adjusted life year burden. Neuroimaging tools such as computed tomography and magnetic resonance imaging are the most efficient for its detection, but low availability and high costs in most endemic regions limit their use. Serological methods such as lentil lectin-purified glycoprotein enzyme-linked immunoelectrotransfer blot antibody detection and monoclonal antibody-based enzyme-linked immunosorbent assays for HP10 antigen detection have been useful in supporting the diagnosis of this disease.

Temporal lobe epilepsy: Evaluation of central and systemic immune-inflammatory features associated with drug resistance.

Neuroinflammation is probably one of the factors involved in drug resistance in people with epilepsy. Finding peripheral markers reflecting the intensity of neuroinflammation could be of great help to decide for which patients anti-inflammatory treatment might be an option. In this context, peripheral cytokines levels and lymphocyte phenotypes were assessed by ELISA and flow cytometry in 3 groups of subjects: drug resistant patients with temporal lobe epilepsy (DR-TLE), non DR-TLE patients and healthy controls.
