Possible ‘cure’ for RA – this one sounds better than the last one …

OK, so I really depressed myself with my last post – what a dumb, trivial thing to get depressed about in the scheme of things,* but that’s the way it is sometimes when you’re an overweight dumpy-frump with curled-up feet and possibly PMT!! So anyway, here’s something potentially more cheerful!

According to The Daily Telegraph this morning, there’s another ‘one-treatment cure for RA’ in the pipeline, and unlike the last one, that needed to be injected into every joint, this really is a one-off treatment that could put patients into remission for years or even a lifetime.

To say it’s early days would be a bit of an understatement, but the good news is that, like most RA drugs, it’s a drug, otelixizumab, that’s already been shown to safe in humans because has already been used ” in much stronger doses to prevent transplant patients rejecting donor organs”. If it works, we’re looking ten years down the line – they’re just about to start the first clinical trial in humans. And if it works the researchers have already said that it might potentially only help people in the early stages; “”However, the chance of this happening in patients who have had the disease for a while is not altogether absent,” says Prof John Isaacs of Newcastle Uni. Oh yes, and at the moment ‘one-off’ is not quite as it sounds – you’re looking at between two and five hours A DAY for FIVE DAYS of intravenous injection. Worse than dialysis. But the point is that unlike dialysis that’s it – you’re cooked. Off you go and hopefully no more RA damage. And also they’re hoping that if they can prove it works, they will be able to produce a different form of the drug that patients can administer themselves (and that presumably will not take ten hours minimum).

This is a nicely balanced article in my opinion – and I rarely say that about medical journalism – it’s not full of the hyperbole that the last one injection cure seemed to bring out and it doesn’t say ‘lots of old people will benefit’ as did the last arthritis article I commented on, although Kate Devlin hasn’t been brave enough to try and say what RA is (probably having seen so many medical journalists shot down when they do that!) The closest she gets is “The condition is different from osteoarthritis, the ‘wear and tear’ form of the disease that typically effects older patients.” Well it doesn’t say much, but you can’t argue with it, really. ;o)

This may not be something that will ever help me (because ten years from now I guess I won’t be considered to be in the early stages of the disease, even if it stays mild), and it probably won’t help you if your’re reading this blog, but anything that really has the potential to ‘cure’ RA (and obviously it won’t undo any joint damage that’s already taken place, but if it stops further damage – great), has got to be good news – and especially good news if you have RA and also have children!

* Not that I’m suggesting your wedding is trivial, Mrs Mooseface!

A ‘one injection’ cure for Arthritis within five years … well, let’s hope so!

Some great news was widely reported yesterday – there might be a cure for rheumatoid arthritis and it could be tested and available within five years. No disputing it, that is great news! But a word or two of caution …

Unlike a drug, this treatment involves taking cells from a patient’s immune system, altering them in the lab and injection them back in to a joint affected by rheumatoid arthritis. However, not only have there been no human trials yet, there have actually been no trials at all. The only work that’s been done so far is on the cells in the laboratory.

The announcement seems a little premature to me because they don’t even know yet whether the re-injection of the cells will cause the ‘fixed’ immune system cells to spread through the body or not.

The injection is likely to cost in the region of £25,000 according to press reports. The cynic in me wonders whether that’s why it’s being billed as a ‘one injection cure’. Because if all it did was halt the disease in one joint, and most RA patients have many joints affected, the cost would be totally prohibitive and perhaps the research would be stopped. According to the Daily Telegraph : ‘The team also hope to find out if the vaccine is effective only in the joints it is injected into, or whether the new cells spread throughout the body.’ So as yet they really have no idea whether it’s a cure or something to help one badly affected joint. And if it affects one joint for £25,000, the ‘National Institute for Clinical Excellence,’ in the UK, (who are the folks that decide whether medication is too expensive to give to patients, and who are often known as NASTY for obvious acronym reasons) certainly won’t be letting us UK folk have this on the NHS!

The BBC’s report quotes Professor Alan Silman, from the Arthritis Research Campaign, who are a charity I hold in great esteem and who are funding this research, as saying that the cells should be ‘reset’ to normal activity, rather than attacking the joints and that ‘The presumption is that they will stay this way, unless the same trigger which is thought to cause the problem in the first place is encountered again. Aye, there’s the rub!!

Not only is this currently nothing more than a presumption, but more importantly we don’t actually know what the trigger is – or I should probably say what the triggers are, as it’s thought that there are many different triggers. So let’s suppose, as has been suggested in the scientific literature, that one of the many triggers is consumption of decaffeinated coffee. If the cell ‘resetting’ is a success and NASTY decides the treatment will be made available an the NHS, then I toddle off for my injection, it works, I feel fantastic for a day or two (and that’s assuming, of course, that it doesn’t have some horrible side effects) and then I have a nice cup of decaffeinated coffee … if that’s my trigger, Wham – flare up – back to square one? I don’t know, but maybe. There isn’t even a comprehensive list of known triggers, so it’s not possible to even avoid them after the injection!

Then there’s the side effect thing – this is, like the current DMARDS and anti-TNFs, something that affects the immune system, stopping it from attacking the joints in error. Again according to the Telegraph article, and they may have got the wrong end of the stick slightly, or I may have, and I haven’t read any scientific paper on this, ‘Using chemicals, steroids and Vitamin D, the team has devised a way to manipulate a patient’s white blood cells so they suppress, rather than activate, the immune system.’ So …where does the immune system go? Is one cured of RA but suddenly unable to leave a big plastic bubble for fear of getting a common cold and dying from it due to lack of immune system? Probably not, because it’s probably very specific cells they’re targeting, but I’d like to understand this a bit better.

Don’t get me wrong, I’m delighted that RA, and cures for it, are being thoroughly researched, and even more glad that there might be a light at the end of the tunnel. As someone said on the NRAS forum yesterday, hope is a good medicine in itself. I’d just have appreciated some slightly more balanced and less gungho reporting.
