PMR and non steroids treatments
Posted , 7 users are following.
my father is 88 and has been treated for PMR a for the past 4 years. He is currently on 17 mg of prednisolone after a flared up of his PMR and COPD exacerbation (he has never been a smoker but had chronicasthma), he also had a small MI 10 years ago. At one point his GP had him on 60mg of pred. He sees a rheumatologist(last time it was a specialist nurse) about every 6 months. He also discovered that he had silent bilateral ruptured Achilles tendons! He is mentally very agile and sociable but loves walking and cannot go very far and only on the flat.
He has never been offered any other treatments for the PMR. He has serious proximal leg muscle weakness and therefore struggles with steps and stairs.
I have several questions.
1. Is his weakness due to the steroids?
2. How good is methotrexate (or other treatments for PMR?
3. How dangerous and effective are other treatments?

There are no real alternative treatments for PMR. Pred is the gold standard therapy and if it is just PMR works well. Did the GP suspect he was developing GCA when he had him on 60mg - there is no necessity for a dose that high in PMR, 15-20mg/day is the recommended starting dose. This is not least because only PMR responds so well to a moderate dose like this - other things (such as other inflammatory arthritides) may respond partially to higher doses and that confuses the diagnosis. About 1 in 6 patients initially diagnosed with PMR have their diagnosis changed at some later point, mostly to another form of inflammatory arthritis and most often to LORA (late onset RA).
Methotrexate is NOT a treatment for PMR. The role of MTX in PMR is that it changes the way the body metabolises pred and is thought by some to mean you get the same effect from a lower dose of pred - it is classified as a "steroid-sparer", there are one or two other drugs used in the same way. All are normally used in rheumatoid arthritis (RA) but none have really shown a reliable effect. Three studies were carried out in the past with MTX: one showed it helped, one showed it didn't, one didn't come to a conclusion. I know people who have been put onto MTX who were initially able to reduce their dose of pred considerably but then had major flares, one developing GCA, and had to go back to 15mg and even above. They still wonder whether they would have had the flares had they been on a slightly higher dose of pred because MTX can never replace the pred and only reduces the dose by a small amount, if it does at all. And it has some quite unpleasant side effects for some people, know as the "MTX hangover".
It does appear that in some cases where MTX, azathioprine and other RA drugs appear to work in lowering the pred dose, that it wasn't PMR but another inflammatory arthritis - it is that dramatic response to a moderate dose of pred that is the sign. When that isn't there the question has to be "Is it PMR?"
One drug that showed promise in a pilot study with 23 PMR problem patients was leflunomide - 22 of the 23 achieved remission of their PMR. It is used on occasions where there is a real need to get the patient off pred for various reasons but if it is going to demonstrate side effects then they are dramatic and can be life-threatening.
If I were your father (or is it you who is concerned?) I'd accept the current status quo, especially if he can reduce the dose again somewhat using a slow reduction - there is one on the forum that has worked very well for a lot of people. At his age it is possible he may need a low dose for the rest of his life but it isn't going to do much damage. Once a patient is down to about 8mg they are in the "physiological range", the amount the body would make anyway.
And for going out - get a mobility scooter. I had decided that if things didn't improve a lot within a few months I was getting one. That was at 60. Occasionally when I look at a rather more demanding walk up slopes I wish I had done so! There is a very small folding one that will fit in any car boot, even a Smartx2!

I would love to hear from anyone who has personal experience of using methotrexate to reduce the amount of steroid used. Using Google scholar the last study I can find using MTX for PMR was 2004! You would think that more would be known now but it seems strange that there is no diagnostic test if it is autoimmune.

They most likely gave up the studies with MTX when it became obvious they weren't going to get a clear answer - in fact, personally I think there is a clear answer: no it cannot be relied on to reduce pred dose. Studies cost a lot of money and are only going to be sponsored when a body thinks it will make a difference to their finances. That is not just pharmaceutical companies but also more public bodies like the NHS or other health care providers. Pred is cheap as chips - everything else is going to cost more overall and actually, most options at present have worse potential side effects. Most pred side effects can be managed - unlike many other drug side effects.
How much of your father's high steroid dose is actually the COPD? You must bear that in mind too. And as I say, many 88 year olds who have never been on pred also struggle with stairs.
I will try to get the people I know who have been on MTX to give a personal opinion on this forum - although I doubt they will say much different to what I said. There really aren't that many who have used it who participate in this forum.

Obviously the Lodotra will suffer more if you are sick. I don't think one night taking it without food will hurt too much - it is just that for reliable 4 hour release the gut conditions must be right. They may release early without food but I don't think it would matter very much - better than no dose at all.

Was it food poisoning or norovirus?
Do hope you feel better soon.

Your comments about Leflunomide are interesting. Google scholar has a reference to an RCT published in 2014, but frustratingly Rheumatology Journal is not open access.
14. A double-blind, randomized, placebo-controlled pilot study of leflunomide in polymyalgia rheumatica Rheumatology (2014) 53 (suppl 2): i8
does anyone know what the conclusions were? Or has anyone been tried on this steroid sparing treatment?

You are where you are now - not 3 years ago.
I will try to find out the conclusions of the study - but it won't be for a few days since everyone is on holiday!

"this was merely a proposal for a study, not the study results themselves.
There is still some discussion as to the final protocol for this"
i.e. this is still very much a work in progress and, on that basis, it is unlikely the study will start within the next year or more. Then it will have to run for at least 3 years, probably more, before any results will be available.
I thought I had already mentioned that I know at least 2 people who have been started on leflunomide who have had to have the treatment discontinued because of side effects, in one they were life-threatening.
Care is required in using leflunomide in patients with pre-existing lung disease and it can itself cause lung disease. Care is also required in using it in patients on anticoagulants. Since it can have severe liver effects it is recommended alcohol is restricted.

as for methotrexate, this is a drug that I hear a lot about and some rheumatologists are now prescribing this as a " normal" medication for PMR. At what point rheumatologists decided that this drug should be prescribed I have no idea as it is not put forward as a recommended drug regimen for PMR. so on those grounds I am going to steer as clear away from it for as long as I can and will fight tooth and nail if for any reason my rheumatologist decides that this drug should be my next step.
there is no set recovery rate for PMR, infact if you read some medical information sheets you would be lead to believe that all of us will be free from this condition within 2 years and most of us will never see a return if it, when in reality the complete opposite is more likely. I believe that drs are prescribing methotrexate because they are attempting to " cure" us within this 2 year timeline. Well, I'm not a clinician but even I know that PMR is an autoimmune inflammatory condition that is self limiting. However, until they find a cure, the drugs we take simply relieve the inflamation and do not speed up the reduction of the inflamation. Therefore, the inflamation will due down as and when it's ready and we simply have yo put up with it and all its twists and turns even if we smile through gritted teeth! All the best for your father. Christina.

It allowed me to drop to 2.5mg pred in a year, which was not the victory it seems as the much lower dose allowed a GCA flare-up of gigantic proportions. Back up to 40mg pred and very unhappy. For reasons known only to PMR, GCA and Pred, this time I had no trouble reducing the dose over the following few months, but what did become obvious was that I was now gaining no benefit from the MTX, and I also began having bad side effects. It was discontinued and I continued reducing Pred without any other help until my current dose of 5mg where I am staying.
It also became clear that I was now free of joint pain, but whether that was the pred, the MTX, or something in the water no one knows. As of this week I amd now query inflammatory arthritis again, but I won't be taking MTX!
My own feeling is that the MTX saw off the joint problems which were the cause of me being unable to reduce at the time, and once they had gone it became a useless addition.
PMR attacked my legs in the first instance and has never let go. I walk daily (on the flat) to keep them moving but have had very limited mobility recently due to another condition entirely. I also have widespread tendonitis, including Achilles tendons, and I do stretches daily to keep me moving as much as possible. I can't go up or down easily, either!
