Filter by:Distal symmetric polyneuropathy, also known as diabetic neuropathy, is the most common neurological complication of diabetes and a main cause of morbidity. The condition leads to gradual loss of function of the longest nerve fibers that limits function and decreases quality of life. Symptoms present distally and symmetrically in toes and feet. Symptoms of the neurologic disability include sensory loss, risk of foot ulcers and limb amputations and pain. The condition is not generally considered reversible, and condition management aims to slow progression and prevent complications. According to estimates from the International Diabetes Federation, diabetic neuropathy affected approximately 425 million people in 2017, with projections indicating a rise to 628 million by 2045. Despite the high prevalence of this condition, it is commonly misdiagnosed and has limited treatment options. There are multiple phenotypes of diabetic neuropathy, with the most common form being distal symmetric sensorimotor polyneuropathy, which is what we will be focusing on in this study. The proposed study seeks to evaluate the effectiveness of a non-compressive therapeutic socks throughout a 12-week course of rehabilitation for managing distal symmetric polyneuropathy. Outcome measures will be collected at standard intervals and compared with pre-treatment measures to evaluate effectiveness of treatment.
Intensive care unit (ICU) acquired weakness is a common complication associated with long-term physical impairments in survivors of a critical illness. The Chelsea Critical Care Physical Assessment tool (CPAx) is a valid and reliable instrument for physical function and activity in critically ill patients at risk for muscle weakness. However, its ability to measure change over time (responsiveness) and the minimal clinically important difference (MCID) have not yet been rigorously investigated. This multi-centre, mixed-methods, longitudinal cohort study therefore aims to establish responsiveness and the MCID of the CPAx in the target population from ICU baseline to ICU and hospital discharge. The study uses routine data from standard physiotherapy sessions like mobility, function and activity with no additional burden for critically ill adults. The investigators expect the CPAx to be responsive allowing its use as a primary outcome in future effectiveness trials for the treatment of ICU-acquired weakness using the newly established MCID for sample size calculation. A high quality, rigorously tested measurement tool for physical function and activity in the ICU should benefit researchers, clinicians and patients.
The main goal of this trial is to establish recommendations for clinical practice that enhance the reliability, accessibility and convenience of sheer wave elastography as a routine diagnostic test for diverse peripheral neuropathies.
The aim of this study is to show how whole body vibration training practiced for 12 weeks affects the levels of inflammatory biomarkers such as C reactive protein (CRP) and, interleukin-6 (IL-6), in Type 2 diabetic patients (T2DM) with and without peripheral neuropathy.
To describe the demographics, clinical characteristics, treatment patterns and clinical outcomes of chronic inflammatory demyelinating polyneuropathy (CIDP), Guillain-Barre Syndrome (GBS), and heredofamilial amyloidosis (hATTR) adult patients at a single U.K. centre.
The objective of this investigator-initiated phase II single-arm open-label clinical trial is to investigate neurological response rate, safety and tolerability of Zanubrutinib 320 mg daily in combination with Rituximab 375 mg/m2 (standard therapy) for the treatment of immunoglobulin M monoclonal gammopathy of unknown significance (IgM MGUS) related polyneuropathy with Myelin Associated Glycoprotein antibodies (anti-MAG). 42 adult patients will be included in two Dutch hospitals (University Medical Center Utrecht and Amsterdam University Medical Center). This trial consists of a 6-month treatment period, after which the hematological response will be evaluated. Adequately responding participants (at least partial response) will be treated for an additional 6 months, after which hematological response will be re-evaluated. Participants with at least a very good partial response will remain on treatment. Non-responding participants will be followed for clinical outcomes only. The total study period per participant will be 36 months.
Chronic dysimmune neuropathies (CDN) are a heterogenous group of acquired inflammatory demyelinating neuropathies including chronic inflammatory demyelinating polyneuropathies (CIDP), Lewis-Sumner Syndrome (LSS), multifocal motor neuropathy (MMN) and other rare entities. Despite their relatively low prevalence, CDN lead to substantial costs for patients and society. CDN are usually misdiagnosed due to progressive nature of the disease with little known data regarding disease activity and treatment response
This study aims to evaluate the safety, tolerance, pharmacokinetics/pharmacodynamics and efficacy of SYHA1402 tablets for the treatment of patients with diabetic peripheral neuropathy (DPN) in China.
The goal of the present study is to determine the occurrence of wild-type and hereditary transthyretin amyloidosis cardiomyopathy among patients with the diagnosis of idiopathic peripheral neuropathy in the setting of a state-of-the-art diagnostic work-up; the investigators believe that the identification of patients with ATTR-CM in this setting can contribute to the early diagnosis of a largely underrecognized condition and, therefore, offer conditions to timely initiation of appropriate therapy with impact on prognosis of patients.
The use of neuroimaging in the evaluation of neuromuscular pathologies is a promising and rapidly expandinf field. Among the different imaging techniques employed, nerve ultrasound is of particular interest given it's non invasivity, lack of side effects, accesibility and low cost. This exam provides complementary data to electroneuromyography (ENMG), enabeling the physician to visualise the morphological correspondents of electrophysiological abnormalities with a spatial resolution at least as good as MRI. Chronic Inflammatory Demyelinating Polyradiculoneuritis (CIDP), Multifocal Motor Neuropathy with Conduction Blocks (MMNBC), Lewis and Sumner syndrome (L-S syndrome) and anti-MAG antibody-associated neuropathies (anti-MAG) are among the main chronic inflammatory neuropathies of autoimmune etiology. The diagnosis of these diseases is based on clinical, paraclinical and ENMG examinations. Several recent studies have highlighted the valuable role of ultrasound not only in the diagnosis but also for follow up of patients afflicted by this group of diseases. However, the current ultrasound imaging techniques does not allow for a detailed study of the internal structure of the nerves. The developement of technologies with improved resolution contribute to further the knowledge in this innovative field and to better understand the pathophysiological mechanisms responsible for initiation and progression of inflammatory nerve disorders.In the Department of Ultrasound at the Nice University Hospital in France the team have at its disposal a high frequency untrasound that the team use to explore the peripheral nervous system. The scientific hypothesis of this pilot study rests on the premise that demyelinationg neuropathies are a heterogenous group where different types present with different morphological characteristics not only at the level of the nerve as a whole, but also at the level of the nerve fascicles and of the peri- and intra-neural vascular structures. In this respect, high frequency ultrasound allows us to visualise different segments of affected nerves and to obtain morphological details which the team then compare with existing ultrasound data in the literature (high frequency ultrasound: 10-20 MHz). Thanks to this non-invasive and painless technique, the nerve can be rapidly visualised along its entire length in static and dynamic mode. In addition, high frequency ultrasound will give us access to complementary data on the morphology of the soft tissues and the peri- and intra-neural vascular structures which may be useful in shedding light on the underlying pathophysiologycal processes. Another important aspect is the opportunity to make electromyographic and clinical correlations The main parameter The team will study in ultrasound will be hypertrophy, corresponding to an increase in the cross-sectional area of the nerve. the team will also conduct analysis on other less codified parameters, such as epineural and endoneural vascularisation (using the Doppler mode), as well as nerve fascicles anatomy (size, organisation). Identification of different characteristics may be of diagnostic interest in cases where the clinical, paraclinical and ENMG examinations do not allow us to make a diagnostic and therapeutic decision, but it can also prove useful in the follow-up of patients and response to treatment. This is a descriptive, pilot, mono-centric, multiparametric and retrospective analysis study on patients followed in our centre with a diagnosis of CIDP, NMMBC, L-S syndrom and anti-MAG
