Active clinical trials for "Peripheral Nervous System Diseases"

In order to clarify the normal components of thermal and painful evoked potentials by heat in normal subjects of both genders and different age group, to clarify the effect of specific anatomy in pain transduction, transmission and modification, and to establish the effect of peripheral nerve and their terminal free ending on the nociceptive transduction, the investigators will use heat stimulation on normal controls and patients with neurological diseases to clarify such issues.

Background and objective The introduction of a proteasome inhibitor bortezomib has significantly improved response rates and overall survival in patients with multiple myeloma (MM), and it has soon become the cornerstone of treatment in both newly diagnosed and relapsed/refractory settings. However, the incidence of peripheral neuropathy related to bortezomib (BiPN) is unignorable and which becomes an obstacle during treatment with bortezomib, either alone or in combination. Until now, there are no consistent findings regarding the risk factors that may cause BiPN. There is either lack of large scale study of BiPN in Taiwan. This study aims to clarify risk factors of BiPN using retrospective analysis in a large cohort with longer observation period as well as the relations between BiPN and gene polymorphisms, and to compare different routes in the incidence of BiPN. Methods This is a retrospective cohort study with a sample size of about 400 MM patients treated ever with at least one full cycle of bortezomib in the institution. All the patients enrolled need to be adults (≧20 years ) with measurable M-component in either blood or urine. The investigators will perform a retrospective chart review to collect clinical data, including anti-MM and concomitant medications, to evaluate the incidence and severity of BiPN in this cohort, as well as any meaningful risk factors contributed to BiPN. The investigators also plan to perform genotyping for the possible genetic factors associated with development of BiPN. Expected contributions The successful collaboration between clinical hematologist-oncologist and biopharmaceutical researcher would result in the concrete evidence of efficacy and safety of bortezomib in Taiwanese patients with MM. The findings in this large cohort study will unveil the risk factors of BiPN, including the administration routes and ethnicity. As results, the investigators would be able to provide the precision medicine-based bortezomib treatment strategy to MM patients in Taiwan.

This project intends to use high-throughput sequencing, molecular biology and bioinformatics technology to clarify the role of target lncrnas in the inflammatory response of DPN, to explore the correlation between target lncrnas and DPN pathogenesis, and to clarify the feasibility of target lncrnas as a marker of DPN cycle.

The goal of this research study is to learn more about pain and other symptoms that patients may experience while receiving chemotherapy treatment with platinum agents, taxanes, and/or bortezomib.

Development of a new MS-based biomarker for the early and sensitive diagnosis of Metachromatic Leu-kodystrophy disease from blood (plasma)

The primary purpose of this study is to determine the degree of loss of epidermal nerve fibers near a foot wound in patients with diabetic foot ulcers. The secondary purpose will be to determine whether the degree of epidermal nerve fiber loss, the clinical examination, nerve conduction studies or the molecular profile correlates with appearance of lower extremity ulcers in patients with diabetes.

This study evaluates peripheral nervous system function using Multiple Excitability Measures (MEM) to obtain "electrophysiological pain phenotypes"

Painful Diabetic peripheral Neuropathy Study of Chinese OutPatiEnt (PDN-SCOPE): a multi-center cross-sectional registry study of clinical characteristics and treatment survey of PDN in China

Exploring the relationship between serum VAP-1 and cardiovascular autonomic neuropathy in subjects with type 2 diabetes mellitus

This study will be an observational study in which patients who have been prescribed Metanx® are invited to participate in surveys regarding their experiences with Metanx®. The purpose of this study is to increase the understanding of the role of Metanx® in managing diabetic neuropathy, provide patients with personalized education and support, and contribute to the overall understanding of the needs and concerns of patients being treated for diabetic neuropathy.
