(If you have received this via email, the following post contains a slideshow and a video, which can be viewed on the Wheelchair Kamikaze website. Please (click here) to view the multimedia content on your web browser.)

Gadzooks! Zounds! Great Gooble Gobble! Late last week Wheelchair Kamikaze received its one millionth page view. 1,000,000! I’m absolutely gob smacked, even though I’m pretty sure about half a million of those page views can be directly attributed to my mother.

In the nomenclature of the Internet, each page view is just what it sounds like, an instance when somebody finds their way to a specific website through a search engine or link and gives it a peek. So, in the four years and 11 months since its inception, my modest little abode on the Internet has been looked at by folks 1,000,000 times, a figure which truly boggles my mind. People from all over the world have visited this place; the stats provided to me by Google show that in the last month alone Wheelchair Kamikaze has been frequented by people in (in alphabetical order): Australia, Belgium, Canada, China, Costa Rica, The Czech Republic, France, Germany, Iraq, Israel, Luxembourg, Malaysia, Mexico, The Netherlands, New Zealand, Norway, Poland, Saudi Arabia, Serbia, Spain, Sweden, Switzerland, Ukraine, United Arab Emirates, United Kingdom, The United States, and Venezuela. Holy crap!

In all honesty, I never expected more than a couple of dozen people to ever look at this thing, as when I started Wheelchair Kamikaze I wasn’t even all that sure of what a blog actually was. I’d been quite active on several online MS forums for a number of years, and during that time several fellow forum members intermittently urged me to start writing a blog, a notion to which I wasn’t all that favorable. I’d never really ventured into the “blogosphere”, and my conception of what a blog could be was fairly limited. In my mind a blog was pretty much just a sort of online diary, and I really didn’t think that what I did or thought would be of interest to anybody outside of the small sphere of human beings who actually knew me.

It wasn’t until my sorry ass landed in a wheelchair, and, at my wife’s urging, I attached a camera to that wheelchair and made a few videos of my wheelchair rides through Manhattan – which friends and family found amusing – that the idea of staking out my own virtual homestead took hold. Okay, I thought, a blog could provide me a place to house the videos and photos I took from my wheelchair, and maybe the occasional scribble or two, in a spot that would be easily accessible to the relatively few people who knew I existed. Never in my wildest dreams did I imagine that this site would provide a conduit through which a part of me could reach out and touch people all over the world, and that in turn these virtual connections would enrich my life in ways that are literally beyond words.

Wheelchair Kamikaze has provided a kind of method to the madness of my being stricken ill, and has many a time proven to be a lifeboat of sorts, helping me keep my head above the churning, tempestuous psychological waters of dealing with my chronic progressively disabling disease. For that I am more than grateful, and to all of the wonderful people who have contributed to those 1,000,000 page views I offer my most humble gratitude, which hardly seems sufficient given the remarkably positive impact creating this blog and interacting with those who view it has had on my life. It may be overstating it to say that Wheelchair Kamikaze has been my salvation, but it wouldn’t be overstating it by much. So, thank you, thank you, thank you.

Okay, with that bit of mushiness done with, let’s get to the business at hand, a rundown of various pieces of MS related news that have garnered my attention over the last few months or so. As usual, these pieces range from the sublime to the ridiculous, and I hope you’ll find them pertinent, useful, interesting, and/or amusing. On with the show…

♦ A new MS drug called Lemtrada has been approved for use in Canada (click here), Australia (click here), and the European Union (click here), but, surprisingly, not here in the United States, where the FDA rejected Lemtrada’s application for approval (click here). The FDA’s rejection comes as something of a shock, as it was widely expected that Lemtrada would receive the FDA’s authorization, despite the problematic side effect profile of the drug.

Lemtrada isn’t actually a new drug; in a previous incarnation, when it was called Campath, it had been used successfully to treat leukemia and lymphoma since 2001. The drug is a monoclonal antibody, a member of the same family of drugs as Tysabri, and works by dramatically depopulating immune system cells in treated patients. Lemtrada is so effective in wiping out its immune cell targets that it in effect prompts the body to “reboot” the immune system, much the same way that certain stem cell therapies attempt to do. The idea is relatively straightforward – wipe clean a person’s immune system, in the hopes that when that immune system is reconstituted it will no longer have an appetite for the patient’s own central nervous system cells. This relatively straightforward concept has proven somewhat tricky to pull off in practice, but Lemtrada does seem to accomplish this feat over an extended period of time.

When used to treat MS, Lemtrada is given intravenously in five day courses two or three times over a 12 month period. After this initial one-year period of dosing, clinical trials have shown Lemtrada to be remarkably effective when given to relapsing remitting patients with active disease. One study (click here) showed that five years after treatment 65 percent of such patients were free of clinically active disease, 72 percent were relapse free, and 87 percent of Lemtrada treated subjects were free of sustained accumulation of disability. In other words, five years after treatment, well over half of the patients given Lemtrada showed virtually no signs of multiple sclerosis activity – they were, for all intents and purposes, MS free.

What then, is the problem? Unfortunately, Lemtrada’s effectiveness comes at a price. Approximately 30 percent of Lemtrada treated patients develop autoimmune thyroid disease, which, though not to be pooh-poohed, can be effectively treated using conventional therapies. More disturbingly, some patients develop an autoimmune blood disease called immune thrombocytopenia (ITP), which, if not caught in time, is often fatal. Patients can be effectively monitored for ITP, but the fact that Lemtrada leaves patients susceptible to the potentially deadly disease is problematic, to say the least.

In those places where it has been approved for use, Lemtrada poses RRMS patients quite a dilemma. Is the prospect of being disease-free five years after treatment worth the risks associated with autoimmune thyroid disease and ITP? Quite the conundrum, but I would think that at least some folks being ravaged by highly active MS, experiencing relapse after crippling relapse, would certainly be willing to take the risk. As we’ve seen with Tysabri, patients can be quite tolerant of risk when a drug dramatically increases their quality of life. It will certainly be interesting to watch as the Lemtrada saga plays out in the regions that have given it approval.

Just as a side note, Genzyme, the drug company that manufactures Lemtrada, engaged in some sleazy activity several years ago by pulling Campath off the shelves when it appeared that the drug – newly named Lemtrada – would sail through the approval process for use as an MS therapy (click here). Why pull Campath off the shelves? Because Genzyme planned to dramatically hike the price of the drug when they changed its name from Campath to Lemtrada and switched focus from leukemia/lymphoma patients to those suffering from MS. When used to treat leukemia or lymphoma, a typical course of Campath treatment cost about $60,000. Since MS patients would need a far lesser dose of the drug, the cost for a course of multiple sclerosis treatment would only be about $6000. So, Genzyme made Campath unavailable and only planned to reintroduce it as Lemtrada once it was approved for use in MS patients, at a dramatically higher price, of course. 

Although the drug has been approved in Canada, Australia, and EU, those places restrict the price of drugs, something that is unheard of in the US, where drug companies can pretty much charge whatever they please. And now the FDA has failed to approve Lemtrada, foiling Genzyme’s Machiavellian business plans. What goes around comes around, as they say…

♦ Having mentioned Tysabri and the fact that it improves the quality of life for many of those taking it, here are two studies that illustrate just that. One study (click here) shows that Tysabri treated patients require less sick leave from work 12 months after initiating treatment. This retrospective study demonstrates that one year after initiating Tysabri treatment, MS patients required 33 percent less sick leave than before they started on the drug. Another study looked at MS patients requiring inpatient hospital stays, and found that Tysabri treated patients exhibited “significant reduction in the percentage of patients with MS related inpatient stays, MS related inpatient costs, and length of stay” (click here).

Most MS patients know that taking Tysabri carries with it the risk of developing a potentially deadly brain infection called PML. Now that Tysabri has been on the market for a considerable amount of time, we have reliable figures as to just what the risks are of developing PML while on the drug. The latest figures indicate that patients who are JC virus negative (JC virus is the pathogen that causes PML) have very little risk of developing the infection, about a 1 in 10,000 chance.

For patients who test positive for the JC virus, two factors come into play in determining their risk of developing PML. The first is whether or not they’ve previously been treated with immunosuppressive drugs, and the second is the amount of time they’ve been on Tysabri. JC virus positive patients who have been treated with prior immunosuppressants have a 1 in 556 chance of developing PML during the first two years of treatment, and a 1 in 89 chance in years two to four.

JC positive patients who have not been treated with prior immunosuppressants need to keep a careful eye on the amount of JC virus antibodies present in their blood, which can now be checked by blood tests. Depending on these levels, the chance of developing PML for these patients in the first year of Tysabri treatment ranges from 1 in 1000 to 1 in 10,000, in years two through four from 1 in 123 to 1 in 3333, and in years four through six from 1 in 118 to 1 in 2500.

The above figures can be viewed nicely in the slideshow below. Click the symbol in the lower right-hand corner of the slideshow to view fullscreen (if that doesn't work, right-click on the symbol and choose "open in new tab"). I’d advise all Tysabri patients to familiarize themselves with these numbers, and make risk/reward calculations based on their individual circumstances, in conjunction with their neurologists. Knowledge is power, people; arm yourselves accordingly.




♦ One of the big problems I have with all of the currently available MS treatments is that they don’t do anything at all to address the root cause of the disease. How can they, since the root cause of MS remains completely unknown? Several recent discoveries may shed some light on that elusive cause, which increasingly appears to be at least partially infectious in nature. In one study, researchers found evidence that a soil-based bacteria, which has rarely if ever previously been found in humans, may be prevalent in MS patients (click here). Researchers reported that “that we identified this bacterium in a human is important enough, but the fact that it is present in MS patients is truly significant because the toxin targets the exact tissues damaged during the acute MS disease process.”

Another study found toxins secreted by bacteria associated with sinus infections in the cerebrospinal fluid of MS patients (click here). This is important because most blood-borne bacteria are blocked from entering the central nervous system by the blood brain barrier, nature’s way of keeping the brain and spinal cord isolated from the nasties that can infect other parts of the body. Infections in the sinuses, though, can circumvent the blood brain barrier by leaking directly from the sinuses into the central nervous system, opening up the possibility that nose to brain transport of bacterial toxins may play a key role in the MS disease process.

Though studies such as these are far from definitive, they do at least attempt to answer THE key question regarding MS: what in heaven’s name causes the freaking disease? There will never be a cure for the MS until that query is answered, and far too little time, effort, and money is currently being spent attempting to unravel this all-important mystery. One would think that such inquiries would be at the forefront of MS research, but instead, because most research is funded by pharmaceutical companies who must turn a profit to survive, the majority of MS research is currently targeted at finding new and better ways to suppress the immune system, resulting in ridiculously expensive drugs that may tame the disease but will never cure it. I’ll practice some self-restraint and stop this line of argument now, before I start ranting and raving and giving myself and my readers a migraine. Arghhh!

♦ Okay, on to one of my favorite subjects, the wonderful world of asinine research. Crack researchers in Germany have determined that spasticity is a problem for MS patients (click here). When I say “crack researchers”, I mean that the researchers must have been smoking crack. How else to explain them wasting time and precious research money conducting a study that confirms what is obvious to anybody suffering from MS spasticity, or anybody observing, even from a distance, somebody suffering from MS spasticity? The researchers could have spared themselves a lot of effort by just asking me or some of my MS buddies about spasticity. Spasticity sucks. End of study.

For those who are blissfully unaware of MS spasticity, the phrase refers to muscles that are rendered stiff and nonfunctional because they receive nerve signals to contract but not the requisite impulses to relax due to the fracked up nature of the MS ridden central nervous system, replete with faulty wiring and short-circuits. Spasticity can afflict almost any muscle in the body, and often causes considerable disability and pain. In fact, many MS patients consider spasticity their most troublesome symptom.

Now, through their earthshaking work, German researchers have, after fastidious and meticulous investigation, determined that “MS patients with spasticity suffer a significant burden because of resulting disabilities and reduced quality of life, especially in cases of severe spasticity”.

HOLD EVERYTHING!!! LIGHT MY PANTS ON FIRE!!! Do they mean to tell me that my twisted and clublike right arm and my clawlike right hand are not doing me any favors, and are in fact a “burden”? That my quality of life might be better if putting on a shirt, sweater, or jacket didn’t require my gimpified body to attempt the moves of a circus contortionist? That the “burden” of my disease would be less if I – gasp – didn’t have any spasticity? And all this time I’ve been gazing upon my twisted and useless appendages with such warmth and affection. Stupid me!

Let me save any researchers currently working on similar studies a lot of sweat and elbow grease. Not only does spasticity decrease quality of life, but weakness and paralysis can also be quite “burdensome”. Yup, arms and legs possessing all of the strength of a fart in a hurricane should not be counted as one of the pleasures of life. Also, bladder and bowel issues are not nearly as much fun as a night at the GiggleSnort Motel. That’s right, contrary to popular belief, urinary frequency and urgency don’t make for a whooping good time. Yes, I’d like to down a couple of pints of icy cold beer as much as the next guy, but I’d better be sitting on a toilet when I do so, because you could calculate the time it takes for the liquid to go from mouth to urethra with a stopwatch. Now, that might be the subject for some fascinating research.

Good grief…

♦ Being “retired” and grappling with a chronic debilitating illness leaves one with plenty of time to contemplate the mysteries of life, wondering just what the hell it’s all about. Gratefully, I came across the following video, in which Father Guido Sarducci (comic Don Novello) explains The Secret of Life. I actually recall the good Father doing this bit on Saturday Night Live back in the late 1970s, when the cast included such greats as John Belushi, Gilda Radnor, and Dan Aykroyd. I remember loving this monologue back then, and the intervening decades have done nothing to diminish its effect on my funny bone. Yup, life is a job, we’re all just here collecting our paychecks, hoping that our balance sheet comes out in the black when all is said and done…


Ciao for now…

Bits and Pieces: Pharmaceutical Follies Edition

Ritalin
Oh, those pharmaceutical companies, always generating such tremendous tidings of joy and overwhelming warm and fuzzy feelings in the hearts of their adoring public. They’ve cured almost every disease that has ever plagued mankind, urged doctors to only prescribe their products when absolutely necessary, kept the price of medicine low enough so that even the most unfortunate can afford their wares, and have conducted their beneficent and altruistic research in a transparent, above the board manner that engenders absolute trust in all of their findings. How lucky we are to…

Whoops! Sorry, I started writing the above paragraph during a brief visit to an alternate universe, one much more to my liking, in which vintage Godzilla movies keep winning Oscars decades after they were made, bacon is a health food, blithering idiots are scorned rather than given their own reality TV shows, and I’m fluent in 10 languages, drive a mint condition 1956 Ford Thunderbird, and am a world-class triathlete. But, since I appear to have suddenly shifted back to this reality, I guess I’ll have to change the tenor of this blog post. Bummer.

I haven’t done a “Bits and Pieces” post in a while, because, well, it’s my blog and I’ll scribble what I want to. There’s been lots of stuff happening in the world of MS, and in the world in general, so in order to limit this post to a length not exceeding War and Peace, I’ll judiciously pick just which bits and pieces of info to highlight. Not that I’ve ever been willy-nilly about picking bits and pieces in previous posts, but I needed an excuse to use the expression willy-nilly, due to an obligation made in an alternate universe. We all must do our part to keep the cosmos in order, you know…

So, presented for your review are the following tidbits of mostly MS related news items, most of them having to do with pharmaceutical companies and their products, with a liberal dose of my take on things thrown in. Bon appétit…

♦ A study which throws into question the efficacy of the interferon drugs (Rebif, Avonex, and Betaseron) to alter the course of MS disease progression (click here) has caused quite a bit of hubbub on numerous Internet MS related forums, blogs, websites, and Facebook pages, and rightfully so. This retrospective study looked at three groups of MS patients, and tracked the course of their disease over a ten-year period. One group was comprised of patients who were treated with the interferon drugs, another of MS patients that were left untreated, and a third was comprised of patients from before the days that the interferon drugs were first made available (they arrived on the scene in the mid-1990s). The study found that patients treated with interferon were no less likely than untreated patients to experience disease progression leading to significant disability.

However, another study, which received much less play in the Internet MS universe, came to the exact opposite conclusion, finding that the interferon drugs do significantly reduce the risk of progression for multiple sclerosis patients across the board (click here).

So what’s going on here? Obviously, it’s hard to say, but, as this article points out (click here), the study that found the interferons ineffective had some possible methodological flaws. One might assume that the population of patients in the untreated group was left untreated because their disease was generally less severe and aggressive than those who were in the treated group, which would invalidate a direct comparison between these two patient populations. If this were the case, the study’s findings would actually show the interferons were effective, because they kept patients with more severe disease from progressing more quickly than those with less severe disease.

Whatever the case, the situation remains as clear as mud. The interferon drugs are much disparaged among many MS patients, because they obviously do not cure MS, cost a fortune, have very unpleasant side effects, don’t work at all for many who try them, and, to top it off, are injectables, and nobody relishes the idea of giving themselves a shot several times a week. What does seem clear, though, is that, at the very least, these drugs do offer some patients relief from debilitating relapses, even if they don’t ultimately alter the course of their disease. Many patients report a severe curtailing of their relapse rates once on the interferon drugs, which amounts to a significant uptick in their quality of life. This benefit cannot be discounted, even if interferons ultimately do prove to be worthless in stopping disease progression, which of course would be disappointing. I’m not one to defend the pharmaceutical companies, but the interferons were never approved under the auspices of stopping disease progression; rather, their approval was based on their ability to reduce relapse rates and the amount of enhancing lesions as seen on MRIs. It was hoped that these two effects would translate into a lessening of disease progression, but that was always just an assumption, a point never tested in clinical trials.

An interesting window into the opinions of patients about this issue is the comments that appear after a piece Julie Stachowiak wrote about the negative study in her always excellent Ask.com MS column (click here). I expected to see a fusillade of outrage voiced by the commenters, but surprisingly, a preponderance of the comments are from patients who say they’ve benefited from the interferons and intent to stay on them because of their increased quality of life. I guess the bottom line is that, drugs or no drugs, MS sucks, and will continue to suck for the foreseeable future. Actually, that’s pretty much the bottom line about everything related to MS…

♦ Here’s an example of a pharmaceutical company snatching victory from the jaws of defeat. The FDA recently warned about seizures associated with the MS drug Ampyra (click here), made by Acorda pharmaceuticals, which is supposed to improve the ability to walk in some MS patients. Much to the chagrin of investors, this warning caused a marked decrease in Acorda’s stock price. Ampyra is given in 10 mg doses, and the FDA asked Acorda to conduct trials to see if a 5 mg dose would be as effective as a 10 mg dose while cutting the risk of seizures.

The results of this follow-up study showed that both the 5 mg and 10 mg doses of Ampyra failed to demonstrate any efficacy in regards to increased walking ability (click here). Acorda claims that this is because the methodology used in this study was different than that of the original studies. Regardless, Ampyra remains on the market in 10 mg doses, since it was previously approved by the FDA based on prior clinical study results. In a happy twist for the drug company and its investors, even though the drug failed the follow-up study, the fact that the 5 mg dose was ineffective means that Acorda retains its long-term patent rights on the 10 mg dose, whereas if the 5 mg dose have been effective copycat drugs could have been manufactured and placed on the market as soon as 2017 (click here). Acorda’s stock price rose on this news, so all is well in investor land, despite the fact that the drug can cause seizures and may be largely ineffective. So, bad news for MS patients, good news for those making money through the marketing of a drug whose efficacy is highly suspect. Talk about alternate universes…

♦ In a case that didn’t work out quite as well for the drug company, Genzyme submitted the drug Lemtrada (formally known as Campath) to the FDA, fully expecting an approval. The company was so confident that the drug would be approved that they started pulling Campath, which had been marketed for years as a treatment for leukemia, off the shelves to keep it from being used off label to treat MS. This was done so that Genzyme could hike the price of the renamed drug to fully take advantage of the more lucrative multiple sclerosis market (click here). After all, MS patients need to take their drugs for years on end, but victims of leukemia either go into remission or die, limiting their necessity to consume drugs. But, ha ha on Genzyme, the FDA turned around and requested that the company resubmit their application (click here), asking the company to change the presentation of the data so the agency can “better navigate the application”, whatever that means. The FDA didn’t order any additional trials of studies to be run.

While it feels good to see a case of corporate greed smacked back, even if only a little, Lemtrada is an interesting MS drug. It is a powerful immunosuppressant, but has been shown in studies to actually decrease the amount of disability seen in patients, even five years after they stopped taking it (click here). This is a result previously unseen with any other MS drug, and may be due to the fact that Lemtrada is such a strong immunosuppressant that it forces the body to rebuild its immune system. This is a similar mechanism to some autologous stem cell treatments, in which a patient’s immune system is completely wiped out with very potent chemotherapy drugs, and then “rebooted” through the use of an infusion of bone marrow stem cells. The effectiveness of the drug does come at a price, though, as 30% of those taking it develop autoimmune thyroid disease, and a smaller percentage develop a serious blood disorder. Unlike Tysabri, though, for some reason the risk of serious infection seems to be quite low, despite the powerful immunosuppressive characteristics of Lemtrada. For patients willing to take the risk, Lemtrada, if and when it is eventually approved, may be the most effective MS drug available. Of course, it only works for RRMS patients; those with SPMS or PPMS are, as usual, left to flap in the breeze…

Having said all that, it sure would be nice if researchers would concentrate their efforts on finding ways to combat MS that don’t tinker with the immensely complex human immune system, since this approach clearly leaves patients open to potentially lethal side effects while doing nothing to actually cure the disease. Perhaps trying to figure out why the immune system goes bonkers in MS patients would be a good place to start…

♦ Just to bolster your confidence that science is aggressively attacking some of the most important issues facing mankind, a cure for baldness appears to be closer than ever (click here). Apparently, Vitamin D holds the key, and researchers around the world are scrambling to finally solve the horrendously tragic and heartbreaking epidemic of typical male pattern baldness, which has brought frustration and shame to men longing to be hairy since time immemorial. Just think about how much time and money is being spent chasing this cherished dream, and how many brilliant minds are dedicated to it. Forget about cancer, heart disease, ALS, and even MS – rejoice, for soon baldness may be cured! I know that I, for one, even with my head full of thick, voluminous hair, will celebrate mightily when the cure for baldness is finally announced. I’ll sit in my wheelchair and feebly raise a pathetically weakened fist as high in the air as my ever more afflicted muscles will allow, reveling in the knowledge that some perfectly healthy bald men will soon be able to proudly make appointments at barbershops and hair salons the world over. It’s all about priorities, people, and mine are definitely in order.

♦ This little bit of news is funny and sad at the same time. Seems an MS suffering grandfather in Scotland forgot he was married and wed his girlfriend, getting into all kinds of trouble due to the fact that he is now a bigamist (click here). The 50-year-old claims he thought his first wife had signed divorce papers, but he apparently forgot that she hadn’t.

In all fairness to the gent, he’d been separated from his first wife for several years, and MS does cause cognitive and memory issues in many who suffer from it. Furthermore, his second wife left him a few months after they were married, and the stress ensuing from this whole mess triggered a relapse, leaving him using two crutches. I’ve had women leave me emotionally crippled before, but this guy really got the short end of the stick. Or, in his case, sticks. In related news, a new study found that ginkgo biloba, an herbal remedy purported to improve cognitive function, had no effect on the cognitive abilities of MS patients (click here).

♦ If you’re in need of a little inspiration, this (click here) infographic about the Paralympics can provide plenty of it. Recently completed in London, this international sporting event for disabled athletes embodies the best of the human spirit. Though the bodies of participating athletes may not fit the standard definition of perfect, their hearts certainly defy definition.

I’ll leave you with the following video, in which a noted brain researcher recounts her experiences during and after suffering a stroke. These experiences provided her with startling and fascinating insights into not only the workings of the human brain, but of the universe and our place in it as well. I have an endless fascination for the mysterious place where science gently kisses spirituality, and this talk navigates that enigmatic realm as well as any I’ve ever heard. It’s 20 minutes long, but I guarantee it’s time well spent, and will provide you fodder for much contemplation…

Bits and Pieces: CCSVI, MS Meds, The Scum of the Earth, and More…

Hula GirlImage by Marie Carter via Flickr

I'll start out with some shameless self-promotion, because it's my blog and I can do anything I want with it. So there.

On Wednesday, April 20, from 8 PM-10 PM, I'll be a guest on the Internet radio show "MSLOL-Radio: "It's All about the Blog" (click here). Hosted by the ever affable Amy Gurowitz (click here), I'll be joined on the show by Lisa Emrich, MS blogger extraordinaire (click here). Listeners will be able to ask questions via phone or instant message, so you'll be able to join in on the fun. Please tune in, if only to hear how many times I can say "um" in a single sentence…

The MS universe was dominated this past week by news coming out of the annual meeting of the American Association of Neurology, this year held in Honolulu, Hawaii. Yes, those neurologists have it rough. There were lots of presentations given on a slew of drugs currently making their way through the research trial pipeline (no shock there), and some controversial reports on CCSVI (no shock there, either). I'll also throw in a few other items of interest (at least my interest), so hopefully you'll find this edition of Bits and Pieces worthy of your time and attention…

  • First, The CCSVI Department: the big CCSVI buzz out of Honolulu was the publication of a paper detailing the results of the Buffalo Neuroimaging Analysis Center's Doppler ultrasound study of MS patients and healthy controls. The initial results from the study were first released over a year ago, but this is the first time they were published in a medical journal (click here).

    The Buffalo researchers found that about 55% of MS patients tested positive for CCSVI, as did about 22% of healthy control subjects. Additionally, about 45% of patients with other neurologic diseases also tested positive for CCSVI. While there is some dispute over the accuracy of the numbers, especially those of the healthy control subjects, some of whom were family members of the MS patients tested (though not all blood relatives), the real ruckus was started by the conclusions of the lead researcher, Dr. Robert Zivadinov, who stated that CCSVI was likely not a cause of MS, but rather appeared to be caused by the disease. This conclusion set off a frenzy of news reports screaming that the entire CCSVI hypothesis had been thrown into doubt (click here and here), and the usual shit storm of debate on Internet MS forums and Facebook pages.

    To my mind, at least, the question of cause and effect is secondary to inquiries as to whether or not treating the venous abnormalities now known as CCSVI actually help the symptoms of MS patients. This can only be ascertained by doing robust treatment trials of CCSVI venoplasty, some of which are already underway, with more coming (click here). The study does show that there is a high correlation between venous blockages and MS, a finding that alone warrants much more study. For some very good reporting on the Buffalo study, please watch the two videos at the top of this article (click here), produced by CTV of Canada. The second contains a substantive interview with Dr. Zivadinov himself, who clearly thinks that his findings do not invalidate the CCSVI hypothesis, but instead beg for robust follow-up studies.

  • The MS Meds Department: predictably, since almost all MS research is funded by big pharmaceutical companies, the MS portion of the AAN meetings was dominated by progress reports on new MS drugs working their way to the market. Two new oral drugs, Biogen's BG-12 (click here) and Teva's Laquinimod (click here) both showed positive results, although the Laquinimod results were found by some (investors) to be disappointing (click here). Interestingly, BG-12 appears to work, at least in part, by being a neuroprotective agent (click here), unlike most other MS drugs, which are designed to primarily suppress or modulate the immune system.

    The MS vaccine Tovaxin, once given up for dead (click here), has apparently risen from the grave, as its manufacturer, Opexa, released positive test result data (click here). According to the research, Tovaxin works best on patients who have had no previous exposure to any other MS disease modifying drugs. Not surprisingly, the price of Opexa stock went through the roof on the news (click here). I'll refrain from making my usual snarky comment about the crass commercialization of disease, and how much it makes me want to vomit. Whoops, looks like I didn't do such a good job at refraining…

    The most dramatic pharmaceutical findings involve a drug known as Campath, produced by Genzyme, which appears to be startlingly effective in eliminating MS symptoms in patients, even for years after they've stopped taking the drug (click here). Campath is a drug given by infusion two or three times a year, and the recently released findings, which involved patients who had taken the drug for three years, showed that after five years 65% of treated patients were free of clinically active disease, and 87% were free of accumulated disability. The drug is not without its downside, though, as 30% of treated patients developed autoimmune thyroid disease. Campath is also associated with a potentially serious blood clotting disorder, and an increased incidence of respiratory and other infections.

    The problem, of course, is that none of these drugs address the underlying cause of MS, which remains unknown. Drug companies are making so much money by finagling with patients' immune systems, and turning those patients into customers for life, that very little research into the mysterious disease trigger, or, more likely, triggers, has been funded and undertaken in the 20 or so years that the autoimmune theory has reigned supreme. This should have every MS patient outraged. Unlike some other MS activist, I can't condemn the current MS drugs en masse, since they do increase the quality of life of a proportion of patients taking them, but the lack of research into the roots of the disease does make my head explode.

  • This brings us to The Root Cause Department: a recent look at disease clusters in the US found an MS cluster in the small town of Wellington, Ohio, in which 25 cases of MS were reported within the six block radius (click here). This would seem to point to some kind of environmental factor (something infectious or toxic) being involved in triggering MS, at least in some patients. There have been quite a few MS clusters identified through the years, but none has ever yielded answers as to what created it (click here). Though these clusters don't prove anything, they do provide plenty of food for thought.

    In my opinion, what we call multiple sclerosis could very likely be a collection of similar diseases, with a wide variety of causes and triggers. Certainly, a genetic predisposition appears necessary, and from patient to patient the trigger that sets off that predisposition very likely varies. Possible triggers could include vascular problems, infectious agents, toxins, dietary and vitamin deficiencies, or a combination of factors. I think it very likely that future MS therapies will need to be tailored to each individual's particular disease characteristics. Of course, the problem lies in sorting all of this out, a process to which tragically few resources are currently being devoted. Too much money to be made figuring out new and better ways of stomping on the human immune system…

  • The What the Fuck Is Wrong with the World Department: I have recently been coming across way too many accounts of crimes being committed against MS patients. From scooters and wheelchairs being stolen (click here and here and here), to MS patients being robbed and assaulted (click here and here) to people masquerading as MS patients in order to make off with donations to MS nonprofits (click here), it's enough to shake my already fragile faith in humanity. I suppose we live in desperate times, but preying on the infirm should warrant some kind of extraordinary punishment. I know that we have supposedly evolved past a simple "eye for an eye" system of justice, but it would be extremely satisfying if the scumbags perpetrating these acts could somehow be given an extremely aggressive form of Multiple Sclerosis. It kills me to watch the nightly news and see a literal parade of the deranged and demented marching past the cameras, walking with ease despite having their hands cuffed behind their backs and hoodies pulled over their heads. I've learned not to expect a whole lot of justice out of the universe, and the notion that life is fair was long ago rendered laughable (even before my diagnosis), but the sight of rapists, murderers, and child molesters sauntering off to jail without so much as a limp calls into question a wide variety of belief systems…

  • The Do You Really Want to Know Department: the Mayo Clinic has developed a test which could indicate how fast a patient who has progressed from RRMS to SPMS will accumulate disability (click here). I certainly understand the practicality of possessing this knowledge, as it would allow for planning and preparation, but I'm really not sure I'd want to know. In some cases, ignorance is still bliss. How about you? Would you want to know?

  • The Eye Candy Department: one of the unexpected pleasures I've had in writing this blog is getting to meet (even if only through e-mail) interesting people from all over the world. WK reader Paulien Bats, from Groningen, the Netherlands, is an illustrator with MS who recently created the image below. I really like it, and not only because Albert Einstein is one of my main men. It's copyrighted and all that stuff, so please don't steal it. Thanks, Paulien…

Inside my head it's a mess
