This study will enroll patients with small fiber neuropathy (SFN). The study will look at an intravenous immunoglobulin (IVIG) called Panzyga. Panzyga is approved by the FDA as a therapy for Primary humoral immunodeficiency (PI) in patients 2 years of age and older; Chronic immune thrombocytopenia (ITP) in adults and Chronic inflammatory demyelinating polyneuropathy (CIDP) in adults. It has not been approved by the FDA for use in SFN. There is mounting evidence that Intravenous Immunoglobulin (IVIG) can cause pain reduction and improve objective nerve fiber densities on skin biopsies in great numbers in SFN patients. The primary outcome is quantified improvement in intraepidermal nerve fiber density (IENFD) on repeat skin punch biopsy after 6 months of IVIG treatment.
This is a prospective randomized control trial. Participants enrolled into the study will be randomized into one of three groups, two of which are treatment groups and the third is a control group. A time course of measurements before and after spinal cord stimulation (SCS) treatment (where applicable) will assess pain, DPN severity, small fiber nerve activity, and metabolic health markers.
BACKGROUND Sjögren's syndrome is an autoimmune disease whose prevalence is estimated between 200 and 500 patients per 100,000 persons in France (120 to 500,000 patients). It affects women (90%) between 40 and 60 years of age and main manifestations are generalized sicca syndrome (ocular, oral, cutaneous) and arthralgia. In 20% of cases, Sjögren's syndrome is associated with peripheral neuropathies, and the most common form is painful small fiber neuropathy (SFN). SFNs are mainly featured by neuropathic pain including burns (90%), numbness (87.5%), tingling (72.5%), electric shocks (70%) and tingling (82.5%) and also autonomic disorders (50 to 70%). However, there are still important issues that deserve to be investigated by clinical and basic research. Among these issues, this study will focus on: * The impact of SFN on the quality of life of patients with Sjögren's syndrome. * The medico-economic impact of the SFN taking into account the repercussions on the quality of life, including professional life, usual care cost (analgesics, medical and paramedical consultations, hospitalizations or emergency). EXPECTED RESULTS * Confirmation of the major impairment in the quality of life of patients with Sjogren-associated SFN * Analysis of correlations to highlight or not clinical or biological factors associated with quality of life impairment. * Evaluation of the cost attributed to the presence of an SFN in patients with Sjögren's syndrome and the pharmaco-economic interest of conventional therapeutic management (analgesic treatment, consultation pain) compared to the cost of more aggressive immunomodulatory treatments.
This research is being done to study a possible treatment for refractory pain due to small fiber neuropathy (SFN). ST-503 is intended to deliver a modified copy of the gene which will ideally repress Nav1.7 tissue-related pain signals reaching the brain, which should reduce the refractory pain due to small fiber neuropathy (SFN).
The primary objective of this study will be to assess the proportion of fibromyalgia patients with diffuse small-fiber neuropathy (i.e. in the upper and lower limbs) and compare this proportion to patients with other chronic pains (nociplastic, nociceptive) and with healthy controls. Our analysis will be based on the demonstration of structural abnormalities of small nerve fibers by means of skin biopsy, but also of functional abnormalities using four validated tests commonly used in this field: quantitative sensory testing (QST), laser evoked potential recordings, Sudoscan and confocal corneal microscopy. It will thus be possible to verify whether or not patients with small fiber neuropathy have a particular clinical profile in terms of pain, physical activity, comorbidities or pain impact.
The diagnosis of carpal tunnel syndrome (CTS) is typically based on clinical findings and confirmatory electrodiagnostic testing. However, electrodiagnostic testing can only assess large A-alpha and A-beta nerve fibers. Quantitative sensory testing (QST) is a series of tests used to assess small nerve fiber changes in the A-delta, c-fibers, and A-beta nerve fibers as well. Previous studies have used QST to assess small nerve fiber changes related to carpal tunnel syndrome and found changes compared to controls. This study will utilize a course of standard physical therapy care and assess for any changes to small nerve fiber activity and how those changes may or may not relate to patient outcomes.
Small fiber neuropathy affects millions of peoples worldwide. The neuropathy is causing disabling burning pain and dysautonomia such as dizziness with standing, brain fog, fatigue, constipation, too much or too little sweating. The detection of nerve damage is complicated and not widely available; it requires either skin biopsy or specialized equipment and training. This project utilizes the mathematical processing of skin pictures for the purpose to extract the statistical features related to loss of small fibers. This approach can improve the availability of diagnosis of small fiber neuropathy.
We examine patients with different autonomic neuropathies and Ehlers Danlos syndromes compared to healthy controls at three different points over time (baseline, after 3 months and after 1.5 years) to gain knowledge about the course of this disease and understand its pathophysiology, with a focus on Small Fiber neuropathy. Moreover we will validate the german version of the Malmö POTS Score and establish an easy diagnostic scheme for patients in outpatient care.
The aim of this study is to determinate if therapeutic exercise with blood flow restriction (BFR) during neoadjuvant chemotherapy potentialy neurotoxic could prevent the onset of chemotherapy induced peripheral neuropathy (CIPN) comparing to usual care.
