Active clinical trials for "Polyneuropathies"

This study compares the efficacy of the ultrasound with fluoroscope in guidance of lumbar sympathetic block (LSB). The goals of the study are; 1) To show that US-guided LSB results in shorter performance time compared to fluoroscope-guided LSB, 2) To evaluate the efficacy and safety of US-guided LSB, and 3) To verify that US-guided LSB has similar success rates to fluoroscope-guided LSB. 50 patients who are supposed to undergo LSB due to sympathetically maintained pain, satisfy criteria of inclusion and exclusion, and voluntarily sign the informed consent will be enrolled.

Background: Distal symmetric polyneuropathy (DSPN) is the most common complication of type 2 diabetes mellitus (T2DM) and the most common form of peripheral neuropathy. DSPN increases the risk of foot ulceration up to seven-fold, and is a significant risk factor in more than 60% of the amputations of the lower limbs in patients with T2DM. Reportedly, TCM may have some advantages in relieving symptoms and reducing the incidence of DSPN exacerbations.We postulate that patients with DSPN will benefit from therapy with TCM treatment according to syndrome differentiation. Methods and design: A randomized, double-blind, placebo-controlled and multi-centric clinical trial design was used on the basis of a co-regimen of mecobalamin. Subjects who met the inclusion criteria were randomly divided into two groups. The patients in the study group were treated with Tangbi prescription, and the patients in the control group were treated with placebo. Treatment was scheduled for 24 weeks. The sample size was 188 cases.Major evaluation indicators: Changes in Clinical Symptoms and Signs in Distal Symmetrical Polyneuropathy patients.The clinical symptoms and signs of patients were recorded by Michigan Diabetic Neuropathy Score(MDNS), and the changes of Michigan Diabetic Neuropathy Score(MDNS) were compared between the two groups before and after medication. Secondary Evaluation Indicators:① nerve conduction velocity changes, The changes in nerve conduction velocity of each nerve were compared before and after taking medicine.② Clinical symptoms and signs change, The clinical symptoms and signs of the patients were compared before and after taking the medicine. Discussion: We postulate that patients with DSPN will benefit from therapy with TCM treatment.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a chronic demyelinating polyneuropathy of autoimmune origin with a progressive or relapsing course. Diagnosis is based on clinical presentation and electrophysiological findings in accordance with the EFNS/PNS consensus guidelines. IVIg is the first line treatment witch has been shown to be effective in several placebo-controlled trials. Once IVIg therapy produces a response and is well tolerated, some patients are able to continue their treatment in the home setting. The HOME LINK system offers an integrated, global solution based on telemonitoring technology providing continuous, remote monitoring of Privigen® infusions administered at home.

Transthyretin amyloid polyneuropathy (ATTR-PN) is a fatal illness resulting from autosomal dominantly inherited single-point mutations on the transthyretin gene. Tafamidis is a specific stabilizer of both variant and wild-type TTR. Tafamidis binds to TTR at the thyroxine binding sites and inhibits TTR tetramer dissociation, the rate limiting step in the amyloidogenic process. The result disrupts the amyloid cascade and fibril formation and interrupts disease progression. This study provides the basis for the study of the effect of tafamidis on the stability of transthyretin and its safety, tolerance and efficacy in patients with transthyretin amyloid polyneuropathy.

Even 20-50% of patients under sedation and mechanical ventilation develops myopathy and / or neuropathy which difficulties both the process of extubation and the functional recovery. The objective of this project is to analyze the effect of muscle electrostimulation (ESM) on muscle weakness acquired in Intensive Care Unit (ICU) and its consequences. Study design: a single center, prospective, randomized trial to be held in the ICU of " Universitarian hospital La Fe" in collaboration with the service of Neurophysiology of the hospital. All patients undergoing sedation and mechanical ventilation (with an expected duration longer than 48h) and without any of the exclusion criteria detailed in the Methodology section will be included in the study. The intervention will consist of a muscular electrostimulation with the Super Pro Excel 70,UltratoneTM. The stimulation will be performed in 10 muscle groups (5 per side) following established protocols, at least 5 days a week. We will evaluate muscle strength by Medical Research Council scale, functional capacity by Barthel scale and Neurophaty Disability Scale, all clinical events will be collected and electrophysiologic, echographic and histologic parameters will be measured. The process of extubation will be performed following an established protocol, the duration will be collected as the same manner as ICU.

This clinical trial is to determine an effective dosage and to study the safety of an investigational drug -lidorestat (IDD-676)- which is intended to stop or slow the progression of diabetic peripheral neuropathy.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a treatable form of peripheral neuropathy with suspected autoimmune cause. The current first-line treatment is IVIG (immune globulin), which is infused in a set regimen that requires 4-5 hours in a hospital day unit, taking up resources such as nursing time and hospital space. Chronic treatment is required in most cases.

The purpose of this study is to determine whether intravenous immunoglobulin (IVIg) is an effective intervention for patients with diabetes, peripheral neuropathy, and demyelination on nerve conduction studies. All patients will receive both IVIg and placebo for 3 months each, with a 3 month washout period in between.

Neuromuscular stimulation (NMES) has been used for several years in the rehabilitation of COPD (chronic obstructive pulmonary disease) patients (among others) to improve their resistance to efforts in everyday life. In patients in intensive care, it seems to improve strength, reduce the loss of muscle mass, prevent the development of CIP / CIM (Critical illness polyneuropathy / critical illness myopathy) and perhaps even reduce ventilation days, with expected effects on the duration of hospitalization and the long-term functional outcome. Although its use could sometimes be limited by the development of peripheral edema and use of vasoconstrictors, the main advantage of this technique is the possibility of being used very early, even in patients that require deep sedation . This is extremely important given that the muscular atrophy process already starts 18h after the onset of invasive ventilation and as signs of impaired nerve transmission are developed in one third of patients at risk within 72 hours. The purpose of the study is to assess the effects, in the short and medium term, of early neuromuscular stimulation in patients who are at higher risk of developing a critical illness polyneuropathy (CIP) / critical illness myopathy (CIM) spectrum disease. This is a randomized controlled single-blind study comparing a group of patients submitted to NMES early (up to 5 days after admission) versus a control group unstimulated.

The researchers intend to investigate possible anabolic effects of bi-weekly exogenous testosterone administration during intensive care unit (ICU) stay for up to 8 weeks. Control group will receive standard ICU management and will also be followed during ICU stay.
