Treatment of Complications to Diabetic Autonomic Neuropathy With Vagus Nerve Stimulation

2019-11-03 15:10:58 | BioPortfolio


The purpose of the DAN-VNS study is to investigate the effects of non-invasive vagal nerve stimulation on gastrointestinal symptoms such as nausea, vomiting, bloating, and diarrhea in people with type 2 diabetes.


The study is a randomized, double-blinded, sham-controlled, parallel group clinical trial, which will include participants with type 2 diabetes and gastrointestinal (GI) problems. These problems may be manifestations of diabetic autonomic neuropathy.

Participants are randomised to received either active non-invasive transcutaneous vagal nerve stimulation (tVNS) or inactive sham stimulation. The study period is divided in two phases. The first phase investigates the effects of short-term, high-intensity tVNS treatment on GI symptoms. The second phase investigates the effects of long-term, middle-intensity tVNS treatment. The primary outcome of both phases is subjective patient evaluation of GI symptoms by the use of validated questionnaires.

A third phase, conducted only on participants, who proved to be responsive to tVNS treatment, will investigate the acute endocrine and metabolic response to short-term tVNS in a randomised cross-over design.

Lastly, healthy volunteers will be included in a cross-sectional, descriptive study in order to provide a comparable baseline dataset.

Medical and Biotech [MESH] Definitions

Traumatic injuries to the VAGUS NERVE. Because the vagus nerve innervates multiple organs, injuries in the nerve fibers may result in any gastrointestinal organ dysfunction downstream of the injury site.

An adjunctive treatment for PARTIAL EPILEPSY and refractory DEPRESSION that delivers electrical impulses to the brain via the VAGUS NERVE. A battery implanted under the skin supplies the energy.

The 10th cranial nerve. The vagus is a mixed nerve which contains somatic afferents (from skin in back of the ear and the external auditory meatus), visceral afferents (from the pharynx, larynx, thorax, and abdomen), parasympathetic efferents (to the thorax and abdomen), and efferents to striated muscle (of the larynx and pharynx).

The inferior (caudal) ganglion of the vagus (10th cranial) nerve. The unipolar nodose ganglion cells are sensory cells with central projections to the medulla and peripheral processes traveling in various branches of the vagus nerve.

The 12th cranial nerve. The hypoglossal nerve originates in the hypoglossal nucleus of the medulla and supplies motor innervation to all of the muscles of the tongue except the palatoglossus (which is supplied by the vagus). This nerve also contains proprioceptive afferents from the tongue muscles.
