How often does PMR progress to GCA?
I'm just wondering how many forum members here had their PMR progress to GCA? I did some research on the latter yesterday evening (perhaps unwisely) and scared myself half to death when I read about the risks of stroke, blindness, aneurysm, etc., associated with GCA. I also learned that the relatively low doses of prednisone we take for PMR won't do anything to prevent the development of GCA -- which was another shock. It seems the percentage of people with PMR who go on to develop GCA varies quite widely in the literature, so I wanted to know what your own experiences have been. I would like to do everything and anything I can to prevent GCA, but it looks like there's not really any way to prevent it -- it just happens in some people, sometimes without warning. How many of you experienced visual problems with your GCA? I have to say that blindness is one of my biggest fears, so reading about people who wake up one morning unable to see out of one or both eyes terrified me. To be frank, I'd rather be dead than blind. Just interested in hearing from those who are actually going through these diseases what your experiences have been with GCA and visual disturbances. Thanks! š

Your husband is lucky to have you as his advocate.
I remind myself that it's called "practicing medicine" for a reason. Our research and practical experience with PMR is often instrumental in our healing.
The UK and Australia seem to be light years ahead of the US in research and treatment for PMR.
I've found several doctors lecturing on YouTube - great information is available.
Thank you! I find the same thing about other countries being ahead. I had not thought about checking YouTube so thank you!!
Hi Isabelle -- thanks for your post, and so sorry you've had to go through so much aggravation trying to get a diagnosis and proper medication protocol for your husband. It scares me how little doctors know about PMR and GCA, and I often worry that if I ever develop symptoms of GCA, the doctors at our ER won't listen and will dismiss my concerns. I'm not the kind of person who likes confrontation, but it seems we have to be downright aggressive at times to get the attention and treatment we know we need. At least my GP is aware of the dangers of GCA, and its connection to PMR, to be aware of the symptoms and try to get attention promptly. I hope your husband will soon start to feel a lot better!
Yes. If you develop some or all of these symptoms (headaches tender scalp, jaw pain, pain when chewing or opening mouth wide, low-grade fever, any vision changes including blurry vision, loss of appetite, weight loss and generally feeling unwell) the first thing is to go to the ER and have labs to check inflammation, followed by an MRI of the brain and CAT scans of the neck, abdomen and chest to rule out other things. Then get a temporal biopsy scheduled ASAP but do not wait for results to increase dose of prednisone to at least 40-60 mg per day to prevent vision loss and stroke (my husband had to have 80 mg after three days of 1200 mg IV infusions of methylprednisolone.) That happened at the ER. I wish Iād known all of this when he developed the symptoms and no one thought he had it. I had to raise h%#* to get their attention. What got their attention finally was when I said he has PMR and now has all the symptoms of GCA except blindness and Iām not willing to wait for that to happen because no one wants to believe us. Thatās when the doctor said if he gets another headache to go to the ER. Which we did in the middle of the night. The doctor there said he was not being treated properly for his condition and immediately started the IV infusion. He has a severe case that did not start to get better until they put him on 80 mg. That was almost 2 weeks ago. As of last week his inflammation went down a little but not as I expected after having those infusions. We go back Monday for more labs and await results for another set of CAT scans of his neck, chest and abdomen. The rheumatologist is not happy with the ones done at the hospital. Evidentially didnāt cover all she wanted it to. Sheās looking for the possibility of something else going on with the GCA. She said it could even be cancer. which freaked me out. And so we wait. At least with the increased Prednisone he's not at such high risk or losing vision or having a stroke. I hope this helps.
Thank you for taking time to share your experience. It is life saving.
You are more than welcome.
Truly frightening what your husband has been through. I'm glad you were able to advocate for him and insist on getting him the treatment you knew he needed. It's very frustrating when doctors don't listen and brush you off, simply assuming that patients don't know what they're talking about. I dread the thought of developing GCA and having to go on high doses of prednisone. I'm doing everything I can to help control the levels of inflammation in my body, although I don't really know if that will be effective.
Hi @charlotte61
I can't say for sure you can avoid it. But. Having been through this horrifying experience I would say you have a lot more knowledge than we did and knowledge, they say, is power. Honestly, if you were to get the symptoms of GCA my first move would be urgent care for labs to check inflammation levels. Those come back rather quickly. If there's a rise, I'd go to the ER and tell them what you suspect. Explain your symptoms, that you've had PMR and are at high risk, and that you do not want to wait to chance blindness or stroke. That seems to get attention. Just listen to your body and don't worry about it because you don't need that additional stress. You know what to do now. The worse is not knowing. And be sure you have a good doctor who will listen to you. It could be something worth discussing at your next appointment. You could share what happened to us and that you want to be assured this will not happen to you. Good chances are you won't get it. Most people with PMR don't. Stay positive, do the things you know work for you and I wish you all the best in this journey. I'll be posting updates as things progress. Next is the results of the CAT scans next week.
According to the following link:
"About 10 percent of people with polymyalgia rheumatica have giant cell arteritis, and about 50 percent of those with giant call arteritis have polymyalgia rheumatica."

"If left untreated, 15%ā20% of patients experience vision loss; however, the rate of vision loss can be reduced to 1% with glucocorticoid treatment.1 Moreover, patients with visual symptoms due to GCA may lose sight in the other eye within days if left untreated.2 These findings underscore the importance of early diagnosis as well as urgent and adequate glucocorticoid therapy."

Early treatment with corticosteroids is key to preventing blindness.

"Of all the people who have been diagnosed with GCA, approximately 20% have vision loss.

High physician awareness, prompt diagnosis and treatment initiation in GCA are important to avoid disease-related damage, especially visual impairment. Blindness continues to occur in 20% of GCA cases, although this rate is lower with early diagnosis and treatment.
Unfortunately, even with early treatment of GCA with prednisone, there are still case reports of people having vision loss.
