PMR connection to GCA

Posted by norieaugustine @norieaugustine, Sep 24 12:35pm

I am okay with some pain when I lower my dosage of Prednisone, rather than no pain with the higher dose. But does this mean more risk of developing GCA? PMR is bad enough but GCA sounds much worse.

Hello @norieaugustine, Welcome to Connect. I have PMR which is currently in remission but when it was active my primary care doctor along with my rheumatologist would frequently ask me if I had any pain in my scalp or temple areas which can be an indication of giant cell arteritis (GCA). I also lived with some pain as I was tapering off of prednisone for both occurrences I had with PMR. My rheumatologist had me keep a daily pain log along with the prednisone dosage I was taking for that day which was helpful when I was tapering off of prednisone. Here's some information on GCA that might explain it a little better.

Can you share a little more about your PMR diagnosis and how long you have been on prednisone?

I've had PMR for almost one year and am now trying to get below 7.5 mg Prednisone, but have not been very successful. I have read quite a lot about GCA and just wonder if there are things those of us with PMR do that make it more or less likely we will get GCA. I will read the posts you mentioned also. Thanks for your welcoming message and the information.

I should have mentioned these discussions also as they might be helpful for tapering off of prednisone.

Hi @norieaugustine, PMR and GCA are "companion systemic inflammatory disorders". In the U.S., the annual incidence of PMR is 52.5 per 100,000 in patients aged 50 and older. The incidence and prevalence of GCA are approximately one-third those of PMR (Cecil and Goldman's Textbook of Medicine). I found an article online, "Treatment of Polymyalgia Rheumatica" in Up to Date which stated that, "The initial dose of prednisone needed to alleviate musculoskeletal symptoms in PMR is lower than used to control vascular inflammation associated with GCA. Treatment has not been shown to improve prognosis or prevent progression to GCA." So whether PMR advances to GCA seems to be out of our control. I have both. The pain and stiffness of PMR were terrible and affected my whole body from the neck down. With GCA, I had a couple of disruptions to vision in my right eye, occasional short stabbing or pulsating pains from my right ear to my eye which increased over time, a tender scalp, and the worst stiff neck ever, with pain on both sides of the back of my head. I went undiagnosed for a year, largely my own fault, because I thought I had fibromyalgia. A mild case of herpes zoster, even after having the Shingrex vaccine a year prior, and anemia brought it all to light through a consult with an infectious disease specialist. My rheumatologist put me on a low dose of prednisone, about 10 mg, then increased it to 40 mg after hearing my symptoms and ordering a temporal artery biopsy which was positive for GCA. My mother-in-law had temporal arteritis, diagnosed in her 80s and she lived to be nearly 100. My maternal aunt also had it. I am managing very well now, down to 7.5 mg of prednisone. One thing for anyone with GCA, my Rheumy told me to take a low dose of aspirin every day as those with GCA may develop aortic aneurysms down the road. I'm thankful these disorders can be managed with prednisone and so far the tapering has been going well. Now I just have to take care of my bones! My suggestion is to try not to worry about getting GCA too much, as it's out of your control, but watch for the signs and report them to your doctor immediately if you get them because the consequences of untreated GCA are stroke or blindness. Best to you.

I have always worried about GCA while decreasing prednisone. Thank you for this information. It is one of the best explanations I have seen. Like so many things, it sounds as though getting it is not in our control, but dealing with it is.

Hi @virginiaj. There are also genetic markers for PMR and GCA, which I haven't seen mentioned very often. These disorders are more common in women and Caucasians, of European ancestry, particularly Northern European. I think you're right – getting the disorder is not in our control. I'm thankful that, for the most part, we have an effective drug to manage symptoms.
