Study Examines Gadolinium Deposits in MS Patients’ Brains, But Still Can’t Determine Relationship with Disease Severity

Here’s some new information about gadodiamide, a contrast dye that is injected during some MRIs. The study confirms that gadolinium, the substance on which gadodiamide is based, builds up in the brain, but the study doesn’t associate that buildup with worsening multiple sclerosis (MS). Missing from this study is whether this buildup affects overall brain health. I think knowing that impact, if there is one, is more important than knowing whether gadolinium affects MS.

The use of gadodiamide, a gadolinium-based contrast agent (GBCA) often used to help clinicians visualize brain structures in magnetic resonance imaging (MRI) scans, leads to the accumulation of gadolinium in certain regions of multiple sclerosis (MS) patients’ brains early in the course of the disease, a study has found.

However, the relationship with disease severity remains unclear.

Those findings, in the study “Cumulative gadodiamide administration leads to brain gadolinium deposition in early MS,” were published recently in Neurology, the medical journal of the American Academy of Neurology (AAN).

UK Researchers Pursuing Breath Test to Diagnose MS

Is it possible that someday breathing into a tube might determine whether or not you have multiple sclerosis, how quickly the disease is progressing, or the efficacy of an MS medication? That idea might sound far-fetched, but it wasn’t that long ago that the idea of wearing a telephone on your wrist was only possible in comic books.

Scientists at the University of Huddersfield, U.K., are trying to develop a breath test to detect volatile molecules exhaled only by people with multiple sclerosis (MS). Doing so might offer a non-invasive and simple way to diagnose the disease.

The research team now plans to undertake a large study involving people with MS to confirm if the breathing test can be a suitable diagnostic tool.

Cannabidiol-based Oral Treatment Seen to Promote Remyelination in Mice, Trial Planned in MS Patients

I usually don’t pay much attention to mouse studies. But this one involves cannabidiol and myelin repair, two subjects of significant interest to people with MS. Also, a clinical trial is planned to begin by the end of this year. So, I’m paying attention to this one.

EHP-101, a cannabidiol-based experimental therapy for multiple sclerosis, was able to recover myelin in damaged nerve fibers and lessen neuroinflammation in a mouse model of MS, data show.

Emerald Health Therapeutics, the manufacturer of EHP-101, also announced plans to open Phase 2 clinical trials in patients by the close of this year.

NervGen to Advance NVG-291 as Potential Remyelination Therapy for MS

Here’s another possibility for repairing damaged myelin. Keep in mind, though, that these researchers are still at least six months away from a Phase 1 clinical trial. 

NervGen wants to advance the development of NVG-291, its lead investigational therapy for spinal cord damage, as a potential remyelination treatment for multiple sclerosis (MS), the company announced.

Following preclinical data showing that NVG-291 promotes myelin repair and regeneration of damaged nerves in animal models of spinal cord injury and MS, the compound has attracted pharma’s attention as a potential therapy for these and other neurodegenerative conditions.

Ed,we are 37 in health care. That is abysmal for what so many people say that we are the "greatest" nation on earth. 37, Ed - 37. I'm appalled at you and this site for leading people on. People - you need HSCT and then get fetal cells. Can you do them in America? No. Why, Ed? You can go anywhere else, but not in America? We are the last nation to do it.
