Filter by:The aim of work is to study the clinical, electrodiagnostic and neurosonographic characteristics of diabetic patients with small fiber neuropathy in the Egyptian population, and to evaluate both the diagnostic and the prognostic impact of the studied factors on the neuropathy severity and quality of life.
Primary Sjögren's syndrome (pSS) is a chronic, immune-mediated inflammatory disease mainly characterized by exocrine gland involvement. Beyond the wide heterogeneity in clinical presentation, neurological manifestation is one of the important systemic involvement of pSS. The prevalence of neurological involvement varies widely from 10% to 60% in different series. Small fiber neuropathy (SFN) as a popular clinical entity in recent years targets nociceptive thinly myelinated A-delta and unmyelinated C-fiber nerves and is frequently associated with burning and allodynic pain. Previous studies have demonstrated that SFN is frequently seen in patients with pSS and has an important clinical importance because it cannot be detected by routine electrophysiological studies. Various methods can be used in the detection of SFN, and cutaneous silent period (CSP) measurement is gaining popularity recently due to its non-invasiveness and practical fashion. In this study, the investigators aimed to compare CSP parameters as an indicator of SFN in patients with pSS and in the healthy population and to reveal its relationship with clinical parameters.
The investigators will treat patients (targeting enrollment of n=20) who suffer from trigeminal or glossopharyngeal nerve pain in the context of painful small fiber neuropathy. The primary pain-related objective is reduction of pain and reduced use of rescue and other anti-pain medications. Another goal is to monitor and confirm the safety profile established in the migraine population, during previous Phase 3 trials.
This study will evaluate the effects of a nutritional supplement called nicotinamide riboside in preventing small fiber nerve degeneration that is experimentally induced by applying capsaicin to skin in otherwise healthy study participants. Furthermore, the effects on nerve regeneration will also be evaluated. The results will be compared to a placebo control drug.
Xanamem™ is being developed as a potential drug for Alzheimer's disease. This study drug has been designed to change the cortisol levels in the brain. Cortisol is a naturally occurring hormone in the body. It is believed that reducing the level of cortisol will be a benefit in the treatment of Alzheimer's disease. The XanaHES study is testing the safety and tolerability of Xanamem. It is planned to enrol approximately 84 participants, male and female aged from 50 to 75 who are in good health, in the study at 1 centre in Australia. The XanaHES Phase I study is a single-blind study. Subjects will be randomised to receive either 20mg once daily Xanamem or Placebo in cohort 1. Once all subjects have completed the study treatment of 12 weeks, a dose escalation committee will decide if a new cohort, cohort 2, with 30mg once daily vs placebo is started.
This study is designed to identify a titration regimen of ABX-1431 in adults with neuropathic pain with satisfactory tolerability to central nervous system (CNS) adverse events (AEs). During the course of this study, each participant will take a daily dose of ABX-1431 or a matching placebo for 28 days.
The objective of this study is to develop a rationale for the selective treatment of small fiber neuropathy with immune globulin (IVIG) in the appropriate patients. The investigators hypothesize that individuals with auto-antibodies targeting neuronal antigens (TS-HDS and FGFR3) and confirmed evidence of small fiber neuropathy (by skin biopsy analysis of intra-epidermal nerve fiber density) will have an improvement in both nerve fiber density and pain after treatment with immune globulin. The co-primary endpoints will be a change in neuropathic pain (by VAS pain score) and a change in intra-epidermal nerve fiber density (by punch skin biopsy). The data gained from this pilot study will establish a rationale, with an appropriate screening test, for the use of immune globulin for the treatment of small fiber neuropathy.
This is a Phase 2, randomized, double-blind, placebo-controlled, parallel-group, multicenter study evaluating the efficacy of VX-150 for the treatment of pain caused by small fiber neuropathy.
FD is pan-ethnic. Its reported annual incidence of 1 in 100,000 may underestimate the true prevalence of the disease. Indeed, recently, in addition with affected males FD developing a "classic" phenotype, " cardiac variant " and " renal variant " have been reported for FD patients with predominant or exclusive cardiac or renal involvement. " Neurologic variant " could exist. Nervous system can be affect by FD leading to cerebrovascular diseases (ischemic or haemorrhagic strokes, TIA (Transient Ischemic Attacks) or peripheral neuropathy (acroparesthesias and pain). Aims will be to determine the prevalence of Fabry disease in patients with stroke or small fiber neuropathy, and their characteristics
Sudoscan™ (Impeto Medical, Paris France) uses electrochemical skin conductance as a novel noninvasive method to detect sudomotor dysfunction. Several small studies have recently shown that Sudoscan use in the assessment of small fiber polyneuropathy (in diabetes mellitus) can be performed non-invasively, quickly and effectively. The investigators aim to study the use of Sudoscan in rare disease condition associated with small fiber polyneuropathy.
