IN DEPTH: Research On Progressive Multiple Sclerosis in 2012

_**As many of us know, the neurological disease Multiple Sclerosis (MS)  has multiple forms **_[1]:

* **_Relapsing-Remitting_  (RRMS)**:    Unpredictable attacks (relapses) followed by periods of relative remission with no new signs of disease activity
* **_Secondary Progressive (SPMS)_** :     Neurologic decline without acute relapses: A sign that one is evolving from RRMS to SPMS is that the baseline drugs[ CRABT]  work less well (Copaxone, Rebif, Avonex, Betaseron and Tysabri); Disability has progressed. _This group is fairly large : about 50 % of RRMS evolves into SPMS within age 40._
* **_Progressive Relapsing (PRMS)_** :     Steady neurologic decline and superimposed attacks.
* **_Primary Progressive  (PPMS)_** :    Decline from the beginning without attacks; problems walking, which gradually get worse; slowly worsening tremor; problems with balance.

_**This still could boil down to two overarching types: Relapsing Remitting and Progressive**_

Most Multiple Sclerosis (MS) new drugs, (See for example, our post on Alemtuzumab [2]), apply primarily  to the Relapsing Remitting Multiple Sclerosis form.

We have posted through the year on the Progressive forms of MS [4-8], and  checking on current research, we gathered the following.

First we bring you, through YouTube, a presentation by Dr Yaung Mao-Drayer, U. Of Michigan [3]. This is a good summary of the challenges of treating progressive MS.

 The most important Chart of this presentation is below. Progressive MS according to Dr Mao-Draayer

Here you would have it, most , if not all the MS big guns address the inflammation phase of RRMS, as opposed to the Neuro-Degenerative phase of the progreesive types of MS.

_**Is it really that simple?**_

* Another study from Denmark [10],  shows that inflammation and neurodegeneration go and progress hand in hand :  "…emphasise a relationship between inflammation, axonal damage and demyelination…"
* From Austria [11]: "..**_.In progressive MS, as in relapsing-remitting MS, active tissue injury is associated with inflammation, but the inflammatory response in the progressive phase occurs at least partly behind the blood-brain barrier, which makes it more difficult to treat_**.  

We did publish about attempts to bring drugs to bear behind the Blood Brain Barrier [6]. intranasal delivery, is being studied for that purpose. Other methods use "…biodegradable polymeric nanoparticles…" [12]

_**Other research avenues against Progressive MS include:** A_ttacking the free radicals oxidation process [a nutraceutical favorite], by administration of oral treatments with Fumaric Esters [13]. Fumaric esters can be found in "…Fumaric acid is found in fumitory (Fumaria officinalis), bolete mushrooms (specifically Boletus fomentarius var. pseudo-igniarius), lichen, and Iceland moss…" (Wikipedia).

Problem Dimethyl fumarate is a potent irritant. Look before you jump…

Other methods we discussed in previous posts are

* Stem Cells:  Stem cells that can differentiate into a variety of cell types, including blood cells [4]
* Masitinib   [5]"… Masitinib, a selective oral tyrosine kinase inhibitor, effectively inhibits the survival, migration and activity of mast cells…"
* Statins: Usually for cholesterol concerns,  Zocor  (Simvastatin)   [7]

Discuss with your Doctor…
