Research: Dysautonomia disorders and related chronic illnesses


The University of Alberta and McGill University released their findings for a new therapeutic agent that may hold the potential for the prevention of MS.

 In the new study, according to the synopsis published in Medical News Today, the researchers examined tissues from donated human brains.  They found that the brains of people with MS had very high levels of a protein called calnexin compared with the brains of people who did not have MS.

The team then used mice that had been bred to model human MS to examine the influence of calnexin in living creatures.

The study authors were very surprised to find that mice that did not have calnexin seemed to be “completely resistant” to MS.

Marek Michalak, from the University of Alberta said that he and his colleagues believe that these findings have identified a potentially vital target for developing future MS therapies.

Neuroprotective Diet for MSA Patients (Multiple System Atrophy)
Information from the MSA Coalition says that although the causes of MSA are still not known, daily food choices can influence certain components of the disease process - slowing or speeding up inflammation, degenerative protein accumulation, nerve cell destruction and decreased neurotransmitter levels.

The diet focuses on calorie restriction, low- protein and protein redistribution combined with an anti-inflammatory diet that includes high antioxidant foods.

FDA Authorizes Marketing of First Blood Test to Aid in the Evaluation of Concussion in Adults

The FDA approved the first blood test to evaluate mild traumatic brain injury (mTBI) commonly referred to as concussion in adults.  The test called the Banyan Brain Trauma Indicator, is expected to be released for use in less than 6 months as a part of the FDA’s Breakthrough Devices Program.  

The test promises to be a better indicator of trauma citing that most people with suspected concussion are examined and given a CT Scan to test intracranial lesions and tissue damage.  However, in the majority of people evaluated, the CT Scan can not detect intracranial lesions. The blood test would give physicians a clear marker to indicate the need for a CT Scan, saving the patient needless exposure to radiation and saving the healthcare system millions of dollars.

Could Targeting Gut Bacteria Prevent Autoimmunity?

Researchers from Yale University in New Haven, CT discovered that bacteria in the small intestine can travel to other organs and induce an autoimmune response.  By administering an antibiotic or vaccine, the scientists found that they could suppress the autoimmune reaction in mice, reversing the effect of this bacteria on autoimmunity.

A few of the illnesses that may benefit most from this research are Type 1 Diabetes,Systemic Lupus, Autoimmune Liver Disease and other autoimmune diseases linked to this bacteria.

The new study complements prior studies that uncovered a link between gut bacteria and autoimmune diseases.One of those studies published in the journal Applied and Environmental Microbiology, showed that species of Lactobacillus in the gut of a lupus mouse were linked to a reduction of symptoms.

Postural Tachycardia in Hypermobile Ehlers-Danlos Syndrome:  A distinct Subtype?

A study was done to determine is patients with POTS and EDS differ from patients with POTS from other etiologies.  The comparison of autonomic testing results along with healthcare utilization in POTS patients with and without EDS was examined.

Results:  The study concluded that while autonomic testing results did not differ dramatically between groups, the patients with POTS and EDS took more medications and had greater markers of healthcare utilization as well as chronic pain playing a prominent role.
