Active clinical trials for "Polyneuropathies"

Chronic inflammatory demyelinating polyradiculoneuritis (CIDP) is an autoimmune disorder of the peripheral nervous system, most commonly affecting the myelin sheath. The pathophysiology of CIDP is not completely understood, but both humoral and cellular immunity appear to be involved in the genesis of this disease. Some diseases are particularly associated with CIDP such as diabetes, monoclonal gammopathies and hematological diseases. CIDP can occur before, after or simultaneously with the onset of systemic diseases. The systemic diseases most often seen in association with polyneuropathies are lupus, Gougerot-Sjögren's syndrome and sarcoidosis. Ultrasound of peripheral nerves is a useful and accessible tool. In CIDP, this examination can reveal diffuse or segmental nerve hypertrophy. In addition to the size of the nerve, this exploration analyzes the echogenicity and the aspect of the different fascicles within the nerve. S. Goedee et al have shown that nerve ultrasound has very good diagnostic parameters and low interobserver variability in the diagnosis of CIDP. F. Härtig et al suggests that nerve ultrasound can predict the therapeutic response and describes 3 main patterns: hypoechoic enlargement (active inflammation), nerve enlargement with hyperechoic add-on fascicles (axonal degeneration) and almost no enlargement ("cured" CIDP).

In this mono-center pilot trial, surgical patients who are at high risk to be admitted to intensive care will be screened and asked for participation. We are going to take blood and muscle samples at respecified time points to do metabolic, histological and molecular testing. Aim of the study is to investigate (1) changes of the blood metabolome in patients with ICUAW (intensive care unit acquired weakness) and (2) identify metabolic components who are responsible for ICUAW or can be used as marker for ICUAW.

The goal of this observational study is to learn about the role of Time-in-Range to stratify the risk of micro vascular complications in adults with type 2 diabetes. The main questions it aims to answer are: Is a lower Time-in-Range associated with a higher risk of diabetes microvascular complications, independent of HbA1c? Is Time-in-Range lower among sulfonylurea and premixed insulin therapy users compared to non-sulfonylurea and non-premixed insulin therapy users, respectively.

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.

In the present study the investigators will search for new genetic variants relevant for the development of neuropathic pain.

National, multicenter, epidemiological, longitudinal protocol to investigate the hATTR prevalence in an at-risk population for Hereditary Transthyretin Amyloidosis (hATTR) and subjects diagnosed with hATTR, to monitor the clinical status in TTR positive subjects and to establish hATTR biomarker/s

The primary aim is to establish a prospective cohort of patients with plasma cell disorders (PCDs). All of the hospitalized PCD patients who are willing to sign the informed consent form (ICF) will be included in this study. Clinical characteristics, treatment options and responses will be collected. Peripheral blood, bone marrow aspirate and urine samples before and after the treatment will banked for future research. Our team will focus on the clinical and pathological features of PCDs, the correlation between the minimal residual disease (MRD) status and prognosis, and the role of Tumor Microenvironment (TME) in the pathogenesis and progress of PCDs.

The primary purpose of this protocol is to create a registry of patients with plasma cell disorders (PCDs), including for example the cancer multiple myeloma (MM), who complete the assessment, previously known as a "geriatric assessment," as is outlined in this protocol. Secondary objectives include measuring the response rate to participation of patients in this study, assessing patient satisfaction with the questionnaire, and gathering information that would lend support for future research into these types of assessments in patients with PCDs. Additionally the study offers an optional blood draw to look at a genetic marker of aging called p16INK4a (IRB 15-1899, IRB 15-0244).

The purpose of this study is to collect and evaluate pregnancy outcomes, pregnancy complications, and fetal/neonatal/infant outcomes in women exposed to patisiran-LNP.

Since the onset of the Coronavirus pandemic disease 2019 (COVID-19), the Lombardy region and in particular the territory of the province of Brescia has been heavily affected. Current data show that the total number of confirmed cases in Italy of COVID-19 due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) exceeds 3.9 million cases, with more than 120 thousand deaths. As the COVID-19 epidemic continues to spread globally, more and more evidence is being gathered about the presence of neurological manifestations and symptoms associated with it. With the growing understanding of the disease, many non-pulmonary symptoms have been recognized, including neurological complications such as acute cerebrovascular disease, meningitis, encephalitis, and peripheral nervous system disease. The main objective of this study is to analyze the clinical and functional conditions of COVID-19 patients with an associated diagnosis of polyneuropathy who were admitted for rehabilitation in the rehabilitation centers of Brescia.
