Undifferentiated Inflammatory Arthritis (UIA)

Posted , 6 users are following.

I live in the US, and my doc originally diagnosed me with "undifferentiated inflammatory arthritis" until I did my own research and found that my symptoms seemed more specific to PMR (started in shoulders, went down into my back and legs, happened within days, and responded almost instantly and completely to prednisone).

However, in reading all these posts I do wonder if many of us fall into that broader category of UIA).  I'm wondering if the UK even uses the phrase "undifferentiated inflammatory arthritis."

From the literature here in the USA, 40-50% of patients with UIA go into spontaneous remission (sound familiar)?  But 30% of patients with UIA end develop rheumatoid arthritis.  The HIGHLIGHT is that those people with UIA need to be on the constant lookout for rheumatoid arthritis because its treatment goal is to stop its progression.  The sooner a patient knows they're dealing with RA, the sooner they can start treating it.

1.  Does the UK acknowledge the existance of UIA?

2.  Might some of the people on this forum fit into that broader category (maybe even myself)?

    I suppose technically that PMR is a UIA - and the consultant I saw wouldn't consider a diagnosis of PMR despite the immediate response to pred, classified it as an "inflammatory arthritis" and wanted to give me sulfasalazine which does zilch for PMR and also has some fairly disgusting side effects.

    I'm part of a research group and last year I had a conversation with one of the research medics asking something similar in the context of the name PMR. It would be better being called polymyalgic syndrome - there are a range of underlying conditions than can cause the symptoms. Some are autoimmune, but cancers can cause similar symptoms too. Calling it PMR suggests to the uninitiated that it is the disease - it isn't, it is the symptom of an invisible illness going on in the background. 

    The Bristol paper I keep on about uses 15mg pred as a diagnostic tool. If a patient is referred to them they give a vit C/pred/vit C sandwich: a week of vit C followed by a week of 15mg/day pred and a further week of vit C. The vit C acts as a placebo - if the symptoms improve by 70% or so within a couple of days of starting pred and then return in a similar time frame on stopping pred it is classified as pred-responsive PMR. They include a graphical representation showing slight improvement in other inflammatory arthritises and the dramatic response in PMR. 

    That is also part of the concept of using a dose of 15-20mg/day at the start. Often doctors use a far higher dose - and most of the inflammatory arthritises will improve on a high dose of pred. That is what happened originally with pred in the 50s. Massive doses were used, the patients got up and walked - they probably had some non-specific arthritis or early stage RA. Only PMR responds in this dramatic way to a moderate dose of under 20mg. 

    Anyone who needs a higher dose to get a decent response should be considered as having another form of arthritis until proven otherwise. And that also fits with the idea of using methotrexate for patients who struggle to reduce pred at all or who get only partial relief. MTX is the first line approach for RA - and probably works for other UIAs. The "PMR" patients who get a good result with MTX probably weren't what we are calling pred-responsive PMR - they get the response you and I got: relief in a few hours.

    So like lions and tigers are big cats and not all cats are lions and tigers, PMR is an undifferentiated soft tissue inflammatory arthritis but not all undifferentiated soft tissue inflammatory arthritis is PMR. The differentiator is the speed of response to the moderate dose of pred. It also forms a differentiator between PMR and fibromyalgia - fibro doesn't respond to pred because the mechanism is different, it is a problem with perception of pain and how nerves are working.

    And did the UIA patients really go on to develop RA later - or was the arthritis simply not identified as being RA in its early stages? I do know someone with RA whose problems started as apparently a form of UIA - she would have pain in one joint one day, another a few days later and it would move around. disappearing between times. I think it is fair to say that the way classical PMR develops isn't like that, joint involvement is unusual unless there is shoulder or hip bursitis and in the hands it is tendonitis and synovitis that can cause pain. But once it starts it tends to progress and you don't get days off!

      Eileen,

      Another excellent post.  I understand all that you said.

      I have to admit that one of my worries is that there's a cancer in the background that's causing all this.  But my brain tells me that the longer I "last" without a cancer rearing its ugly head, the less likely there's a cancer lurking in the background.

      I think there are specific ones that should be looked for and that is part of the work up at the start. This paper

      Is cancer associated with polymyalgia rheumatica?

      A cohort study in the General Practice

      Research Database

      Sara Muller, Samantha L Hider, John Belcher, Toby Helliwell, Christian D Mallen

      does suggest we should be more closely monitored for a year or so. I don't know if your medical technical language is up to reading it but the conclusion fits what you say - the longer I have had PMR with no cancer diagnosis the less likely it becomes!

      The figures in this paper show an increase in dx's of cancers in the first 6 months after developing PMR but a return to pretty much the same as others thereafter. The obvious conclusion there is that there were mis-diagnoses at the time. There are cancers that become more likely later - colon cancer is one and some of the associated cancers they mention would be picked up by blood tests. And the fact remains that once we have one autoimmune disorder we are more at risk of developing another. Plus, taking pred does help reduce the risk of some of the cancers that develop as a result of long term systemic (all over the body) inflammation. Pred may be not nice - but it isn't all bad.

      Thanks Eileen.

       We've had exchanges before but now I have a question - I have my Rheumy's advice, and knowing you aren't offering medical comments,. The question is whether , given what you and others know from experience, I should take a course of metotrexato ( the Spanish name) for three weeks , followed a day later by some folic acid pills, in the hope of being able thereafter to drop my intake of preds? 

      I don't like the look of the list of possible side effects given the other meds I am on, beta blocker, blood thinner, heart beat regulator, etc.  Stuff  I had never heard of or thought were for true geriatrics- I'm a mere 73.5 and fairly fit, although for now I no longer think of marathons  at 90- 4-5 kms on a good  day is getting to be tops.

      I had worked my way down, some seven months after the sudden onset of CGA to 11.25 mg of corticosteroids per day. Then for reasons unknown the symptoms of the truly ugly cousin PMR hit me. My ESR ( sedimentation rate) suddenly went from normal- 12 or so to almost ten times that between blood tests. I was quickly put on a new dose of 50 mg of pred, and have worked that down to 20mg per day. But that seems about as low as I can go before I encounter back , wrist and leg pains. Those are manageable with some accupressure and non blood thinning pain killers.

      Not directly related , but I see there are some new and potentially relevant discoveries as regards antiviral treatments out of Oxford and Bristol universities. You are no doubt well informed. Also from the USA comes a report to the effect that many of the familiar PMR symptoms are also seen in a condition, not previously well explored called "adrenal deficiency". I suppose that can  be searched for on the net- I have a copy of the report, but it seems I can't post it, nor can I show a website on this service. The reason for mentioning it is that this problem appears to be not just treatable but curable. I wish CGA and PMR were as well. Maybe they will go away- let's hope.

      Keep up the wonderful work.  And please comment, if you can't  entirely answer my question above. I plan to start the metrotrax injections in the next day or so, while maintaining the pred level for while until can meet my rheumy again..

      Regards, Charles

      ps: Is it possible to draft atext in for example Word  copy and transfer in to this blog? That would make its use much easier. C

      Last first - yes, you can write your post in Word and then copy and paste it into a post here.

      Next, yes you CAN put in links but they will disappear until they have been checked out by the moderator - they are captured automatically when you write an internet address or also certain words trigger it. if they are OK the post will be returned once they have been checked.

      Now you have got to 20mg - how are you reducing? I would hazard a guess that it was GCA that was returning if the sed rate shot up that far - and PMR symptoms are also a symptom of GCA but the prompt return to 50mg hit that hard. There was no need to go back to 50mg if the doc only thought it was PMR, so it suggests he thought it was GCA too. At those high doses 5mg reductions will be fine for most people. But no reduction should be more than 10% of the current dose and for many patients even that is too much. 10% at 20mg is 2mg - 5 would be WAY too much. 

      There has been a lot of discussion about reduction on all the forums and 2 versions of a "dead slow and nearly stop" reduction plan are doing the rounds, many people have tried them, almost all successfully. One is being used by a consultant in the northeast of England - even he is impressed! I never got below 9mg without the symptoms you describe appearing - until I used the reduction plan you will find in posts 4 and 5 of this thread on this forum:

      https://patient.info/forums/discuss/pmr-gca-and-other-website-addresses-35316

      If you are still on 20mg then the adrenal deficiency question shouldn't arise - the body makes the equivalent of about 7 or 8mg pred of a natural corticosteroid called cortisol. The body doesn't care whether it is natural or artificial, it is a corticosteroid, and there is plenty of it swilling around your body. 

      I can't comment in detail about the USA report about adrenal insufficiency since I haven't seen it - but is it "real" science? Adrenal insufficiency can't be "cured" - and it is certainly something doctors are aware of. Some patients never get off pred because they need a low dose to compensate for poor adrenal function but it is usually a dose well below 10mg. What is actually not clear is whether it is the adrenal glands themselves or the complex feedback set-up that governs adrenals, thyroid and other organs in producing hormones. But adrenal function should be checked at low doses of pred if patients can't get off pred altogether. I don't think that applies for you yet.

      The most recent comment is (finally) that mtx doesn't have a role to play in PMR - and has always been it has no role to play in GCA though there are many doctors who do believe it works. The studies done are inconclusive: one said it works, one said it didn't, one didn't know. It is certainly another set of side-effects to consider and they can be unpleasant. One big PMR/GCA cheese in the UK supported using mtx - but about 18 months ago was co-author of a paper on a research project where it stated quite categorically that mtx was not useful in PMR or GCA so that other approaches must be sought. Personally, I wish he'd say it rather more publicly.

      I know 2 ladies who were initially able to reduce their pred dose only to have quite severe relapses, one going from PMR to GCA developing despite being on pred and mtx. It changes the way the body metabolises pred so that you may be able to manage on a lower dose which achieves the same effect. Or not. The mtx doesn't replace the pred - unless you really have late onset rheumatoid arthritis which can appear identical to PMR in the earlier stages. mtx is the first line approach for treating RA - for those patients, and there are quite a few, mtx will work better than pred. 

      Before starting the mtx I would try reducing using the very slow approach I have given you the link to - that may achieve the desired result without the pain. I'll lay odds it is steroid withdrawal pain and the mtx won't change that. A very gradual reduction will.

      Thanks Eileen. To late to put you up for the Noble prize for medicine this year, but look out in 2015.

      Ciao, Charles

      Sorry for the typos- I actually can spell "too" and know the difference betweeen Noble and Nobel! ( as some of my erstwhile graduate students at Yale would  well recall) .My note got away on me. I'll work from Word or some such in future .

      We've begged for edit facilities on this forum - it is the only one I use that doesn't have it! Not even wiggles under wrong spellings so you notice it sooner! They can add rubbish like "like votes" (you could vote for yourself for goodness sake) and star awards - which have only to do with quantity not quality. But something useful? Apparently too difficult...

    Interesesting, since I (a PMR patient) was just diagnosed with Rheumatoid Arthritis. Verified by xrays of the hands & feet.  The arthritis shows dark in the bone whereas healthy bone is white.  Any way, I hike and came into a nasty infrestation of very small ticks - bablies called Nibbs. Recieved about 100 bites. Thank goodness, I am on 15 mg of Prednisone or things would have probably been worse. My arthritis doctor said I had better take an antibiotic (Doxycycline Hyclate 100mg twice a day) for a month. She was afraid of Lyme disease from the ticks. Waiitng for my blood test results any day.  She said, a small group of doctors believe this antibiotic can help with the RA. Some have been on very low doses for years w/o problems and it seems to help some people.  Just puting this on here just in case it may help others. At least, it is something else to consider and will help support our immune systems. Thank you for your information Eileen. Good luck to everyone.

      And I find that interesting too! 

      After the PMR was "diagnosed" (it's in quotes because it wasn't diagnosed as such - I asked if it could be???) a Hungarian colleague of my husband told me his wife had had something almost identical to me which was relieved by pred - but only at higher doses and she had unnacceptable side effects. He is a medical doctor although he does research rather than practising and together with the local rheumatologists they treated her with an antibiotic for a couple of years and it did the job. I suspect it was doxycycline but I haven't managed to get anyone interested in thinking about it. What I also know is that a few people have said they felt much better for a time after being on antibiotics for other problems. 

      There have been a few clinical trials ongoing in recent years looking at the effect of minocycline and doxycycline in RA - they doesn't cure it but modify the joint damage. It also has an effect on protein synthesis in the mitochondria - I wonder if that has any role to play.

      Wow maybe you're onto something there - it may be worth looking into.  I often get the little nymph tick bites and ocassionally a bite from mum or dad as well.  Just pull them off and here I am with PMR - could it be linked - who knows - more research should be done.  Those little b's could be giving me all these aches and pains or not.

      It's certainly possible that your "PMR" is the symptom of something else - Lyme disease is one that should be ruled out but it hasn't been on the radar in the UK as everyone thinks that's a "foreign" disease! Not any more though!

      Concerning Lyme Disease......Within a month, the following signs and symptoms may occur if you've been infected by Lyme Disease from a tick....

      Small, red bumps will appear at the site of the tick bite. Theses small bumps are normal after a tick bite and doesn't indicate Lyme disease. Over the next few days, the redness may expand forming a rash in a bull's-eye pattern, with a red outer ring surrounding a clear area. For some people, this rash can appear at more than one place on their bodies. Fever, fatigue, body aches, chills and a headache may accompany the rash. It will seem like you have the flu.

      Later Symptoms: The rash may spread to other parts of the body.  Several weeks to months after you've been infected, you may experience:

      You may develop bouts of severe joint pain and swelling. Your knees are especially likely to be affected, but the pain can shift from one joint to another.

      Weeks, months or years after you were infected, you may experience neurological problems such as inflammation of the membranes surrounding your brain (meningitis), temporary paralysis of one side of your face (Bell's palsy), numbness or weakness in your limbs, and impaired muscle movement. Less common symptoms: Weeks after infection, you may develop: Heart problems, such as an irregular heartbeat. Heart problems that may last more than a few days or weeks. Liver inflammation (hepatitis). Eye inflammation and Severe fatigue. Doesn't this all sound familiar? I had a test recently for Lyme Disease and it came back negative so doctor recommended repeating the test again in a month.  I have been bitten by ticks over my lifetime so this Lyme connection may be really something the doctors/researchers SHOULD look into. It is possible isn't it, that we fend off the initial symptoms (meybe when younger) and it lies dormant for years?  Something like Shingles???

      I'm in Australia in an area that is not supposed to have Lymes disease, however as in the UK with all the travellers etc it is possible that it is spreading throughout the world unchecked.  I'm not sick enough to have Lymes but who knows what else the ticks carry or damage they do to ones system.  I'm only wondering out loud as noone seems to have done the research and where would they start anyway.  Wouldn't it be fabulous if we all found a common thread with PMR so the clever people could look into it and solve this seemingly growing epidemic

      Umm  Good point  - its a bit like everything when you're young seems not to be a problem but it gets you later as you age

      I checked with the Conservationists from the area I had received the tick bites. They said there are several tick borne diseases Besides Lyme Disease there is Ehrlichiosis which has been recently recognized as a tick borne disease.  Early symptoms are high fever, fatigue, headaches, muscle aches and sometimes, a rash that will appear within 5-10 days. This diease attacks blood cells and must be treated immediately with antibiotics..  If left untreated, the can do damage to the joints, nervous system.  Also can occur chronic pain, arthritis, cardiac abnormalities and numbness.

      Other tick borne diseases: Tularmia, Babesiosis, relapsing Fever.

      My dear wife contracted Lyme Disease several years ago.  It went untreated until she eneded up in intensive care.  They finally did the blood tests, and treated her with the right antibiotics.  That was 3-4 years ago.  It is a debilitating disease -- something NOT to be taken lightly.  If treated rapidly, its effects are not as bad, but left untreated it does all that you said it does.  It's awful.

      I will never be so gung ho about tick bites again
