MS news notes: Diagnosing PPMS, NB-4746, Neubie stimulation

Welcome to “MS News Notes,” a column where I comment on multiple sclerosis (MS) news stories that caught my eye last week. Here’s a look at what’s been happening:

PPMS is difficult to diagnose, report says

Most people who have multiple sclerosis start out with a diagnosis of relapsing-remitting MS, but a small number begin with a primary-progressive MS (PPMS) diagnosis. That’s when symptoms gradually worsen over time right from the start.

There are guidelines, called the McDonald criteria, that determine MS type using time of progression, MRIs, and lab tests. But as the MS News Today article “Diagnosing primary progressive MS difficult, despite guidelines” reports, it’s still a tough call to make.

The story looks at a study in the Netherlands that reviewed data from 322 people diagnosed with PPMS between 1974 and 2019. The researchers found that only 228 of them actually met the criteria for a PPMS diagnosis. According to the study, some had other health problems that may have affected the diagnosis. For more than 100 others, it was unclear whether the progression started at disease onset, meaning it’s possible they could’ve had a relapsing form of MS.

This problem doesn’t only concern PPMS. Many people with MS have told me they’re unclear about when their disease status changed from relapsing to secondary-progressive MS. That was certainly the case for me. But does it really matter what your MS is labeled — except to insurance companies that determine which treatments they’ll cover based on the diagnosis?

Multiple sclerosis makes it tough to deal with the heat of the dog days

Patient testing begins on experimental treatment for nerve damage

Clinical testing is starting for an investigational treatment that aims to block an enzyme contributing to the damage of axons, the long fibers that connect nerve cells. The study is important for people with MS because, as the article “Experimental MS therapy NB-4746 to be tested in healthy volunteers” reports, if axons are damaged, the result can be problems with senses, motor functions, and cognition — all typical MS symptoms.

In this Phase 1 clinical trial, only healthy people will be trial subjects. But Nura Bio, the company sponsoring the NB-4746 trial, expects to begin clinical trials using MS patients sometime in 2024.

An electronic device that aides physical therapy

I’m currently in the middle of twice-weekly physical therapy sessions. I have periods of it a couple times a year to loosen my stiff legs and back muscles and to improve my core strength.

As reported in “Neubie electrical stimulation device found to help in progressive MS,” using an electronic device that stimulates nerves and muscles as an add-on to physical therapy could improve strength, range of motion, and spasticity in people with MS — all things that I need. The stimulation essentially works to reeducate, or reboot, the neuromuscular system and restore it to more normal functioning.

The Neubie — which stands for “neuro-bio-electric stimulator” — is cleared by the U.S. Food and Drug Administration, but not specifically for treating people with MS. It’s made by the company Neufit.

Courtney Ellerbusch, a physical therapist in Colorado who spearheaded the effort to further test the Neubie device on MS patients, says she did it “for the individuals who face a daily reality in MS that has changed everything about their lives.”

MS hasn’t changed everything about my life over the past 40 years, but thank you for your efforts, Ms. Ellerbusch. Every little bit helps.
