Article Synopsis
  • The study aimed to assess the safety and effectiveness of caprylate/chromatography-purified intravenous immunoglobulin (IGIV-C) in patients with generalized myasthenia gravis (MG) compared to a placebo.
  • A total of 62 patients participated in a randomized trial, where IGIV-C showed a numerical improvement in certain outcomes like activities of daily living, although most primary and secondary outcomes did not reach statistical significance.
  • While IGIV-C was generally well-tolerated, the small size of the study suggests the need for further research to better understand its potential as a maintenance therapy for MG.

Introduction: Subtle abnormalities in the preclinical stage of Huntington's Disease (HD) can be detected using saccadic eye movement assessment reflecting disease progression. This study was aimed to evaluate abnormalities in saccade parameters in asymptomatic carriers and symptomatic HD patients at various stages of HD.

Material And Methods: The study enrolled 104 participants, including 14 asymptomatic carriers of HTT mutations, 44 symptomatic HD patients, and 46 control subjects.

Multiplex arrays designed for enzyme-linked immunosorbent assays (ELISAs) are robust and cost-effective for profiling biomarkers. Identification of relevant biomarkers in biological matrices or fluids helps in the understanding of disease pathogenesis. Here, we describe a sandwich ELISA-based multiplex assay to assess growth factor and cytokine levels in cerebrospinal fluid (CSF) samples derived from multiple sclerosis patients, amyotrophic lateral sclerosis patients, and control subjects without any neurological disorder.

Background And Objectives: Myasthenia gravis (MG) is an autoimmune disease characterized by dysfunction at the neuromuscular junction. Treatment frequently includes corticosteroids (CSs) and IV immunoglobulin (IVIG). This study was conducted to determine whether immune globulin (human), 10% caprylate/chromatography purified (IGIV-C) could facilitate CS dose reduction in CS-dependent patients with MG.

Objective: To investigate safety and explore efficacy of efgartigimod (ARGX-113), an anti-neonatal Fc receptor immunoglobulin G1 Fc fragment, in patients with generalized myasthenia gravis (gMG) with a history of anti-acetylcholine receptor (AChR) autoantibodies, who were on stable standard-of-care myasthenia gravis (MG) treatment.

Methods: A phase 2, exploratory, randomized, double-blind, placebo-controlled, 15-center study is described. Eligible patients were randomly assigned (1:1) to receive 4 doses over a 3-week period of either 10 mg/kg IV efgartigimod or matched placebo combined with their standard-of-care therapy.

Objective: There is no existing standard, evidence-based, scientific model for motor ability improvement in Huntington's Disease (HD) patients aimed at maintaining independent gait for as long as possible, or performing activities of daily living, the effectiveness of which would be supported by the results of studies using objective research tools. Under these circumstances, the aim of this study was to analyze the influence of motor ability rehabilitation on the spatial-temporal parameters of gait in HD patients.

Design: It was an experimental trial.

Objective: To evaluate the effectiveness of reinforced feedback in virtual environment (RFVE) treatment combined with conventional rehabilitation (CR) in comparison with CR alone, and to study whether changes are related to stroke etiology (ie, ischemic, hemorrhagic).

Design: Randomized controlled trial.

Setting: Hospital facility for intensive rehabilitation.

Introduction: Parkinson disease (PD) is the common neurodegenerative disease. α-Synuclein (ASN), main aggregating protein in neural cells of CNS in PD, was found in peripheral fluids. Testing ASN in plasma is potential test for diagnose PD, but previous studies are controversial.

Objective: Genetic background of cryptogenic ischemic stroke (IS) and transient ischemic attack (TIA) remains uncertain. Alpha-2-antiplasmin (α2AP) Arg407Lys polymorphism has been shown to be less common in patients with abdominal aortic aneurysm (AAA) compared with healthy controls. We investigated associations of α2AP Arg407Lys polymorphism with cryptogenic IS and TIA.

A number of studies on gait disturbances have been conducted, however, no clear pattern of gait disorders was described. The aim of the study was to characterize the gait pattern in HD patients by conducting analysis of mean angular movement changes the lower limb joints and trunk (kinematics parameters). The study group consisted of 30 patients with HD (17 women and 13 men).

Unlabelled: Apart from intention tremor essential tremor (ET) patients may display other cerebellar signs, like dysmetria or tandem gait disturbances as well as parkinsonian signs like resting tremor, cogwheel sign, subtle bradykinesia. Previous reports claimed the occurrence of the eye movement abnormalities characteristic for dysfunction of cerebellar dorsal vermis in ET patients with concomitant cerebellar signs. There are no previous reports evaluating the eye movement abnormalities in ET patients with concomitant parkinsonian signs.

Objective: To assess the effects of l-dopa and deep brain stimulation of the subthalamic nucleus (DBS-STN) on saccadic eye movements in patients with Parkinson's disease (PD).

Methods: Visually and internally guided horizontal saccades were evaluated using a saccadometer in 64 patients with advanced PD and 48 healthy controls. Forty-four pharmacologically treated patients were assessed in their "med-off" (OFF) and "med-on" (ON) status, whereas 20 DBS-STN treated patients were assessed in their "med-off, stim-off" (OFF) and "med-off, stim-on" (ON) status.

Essential tremor (ET) is the most prevalent movement disorder, characterized mainly by an action tremor of the arms. Only a few studies published as yet have assessed oculomotor abnormalities in ET and their results are unequivocal. The aim of this study was to assess the oculomotor abnormalities in ET patients compared with the control group and to find the relationship between oculomotor abnormalities and clinical features of ET patients.

Computational approaches for modelling the central nervous system (CNS) aim to develop theories on processes occurring in the brain that allow the transformation of all information needed for the execution of motor acts. Computational models have been proposed in several fields, to interpret not only the CNS functioning, but also its efferent behaviour. Computational model theories can provide insights into neuromuscular and brain function allowing us to reach a deeper understanding of neuroplasticity.

Objectives: The published data on the relation between arterial hypertension (AH) and hemifacial spasm (HFS) are controversial. The aim of the study was to determine the prevalence of AH in HFS patients and the relation of AH and compression of the brainstem at the region of vasomotor center.

Materials And Methods: The study included 60 of primary HFS patients and 60 healthy controls matched by age.

Stiff person syndrome (SPS) is a rare autoimmune neurological disorder with antibodies against antigens involved in neurotransmission of gamma-aminobutyric acid (GABA). About 10% of patients with SPS may develop ataxia. This cerebellar variant is a distinct subset of SPS with more severe and complex clinical phenotype.

Neuropathic pain may be caused by a variety of lesions or diseases of both the peripheral and central nervous system. The most common and best known syndromes of peripheral neuropathic pain are painful diabetic neuropathy, trigeminal and post-herpetic neuralgia, persistent post-operative and post-traumatic pain, complex regional pain syndrome, cancer-related neuropathic pain, HIV-related neuropathic pain and pain after amputation. The less common central pain comprises primarily central post-stroke pain, pain after spinal cord injury, central pain in Parkinson disease or in other neurodegenerative diseases, pain in syringomyelia and in multiple sclerosis.
