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! 🙂

GCA is for Giant Cell Arteritis. I would highly recommend seeing a rheumatologist for vision change if you have PMR. My husband had PMR and later developed GCA. It’s a very serious condition. To diagnose it they checked his ESR and CRP blood levels for inflammation and scheduled a temporal biopsy which showed he had inflammation of his blood vessels. He was put on high dose prednisone which wasn’t working so we ended up in the ER where the ER doc put him on a very high dose of methylprednisolone (1200 mg) for three days. His inflammation finally started going down. We’re a month into it and his levels are normal. They have him on 80 mg prednisone splitting the dose 50 in the am and 30 in the pm. He just stated weekly Actemra injections which his doc says he’ll need 2-3 years. With the goal of greatly reducing his need for prednisone. Good luck! I hope you don’t have or get GCA. One more things. His PMR was under control. He had been diagnosed in May 2023. He was down to 12.5 mg prednisone and pain free. Then this February he started getting horrible headaches, jaw and scalp pain, his temples were sensitive and there were times his temples were inflamed. He lost his appetite and has lost weight through this process. He’s had multiple CT scans and labs done to rule out cancer.
I’m so glad you pushed the issue with your doctor. My husband’s rheumatologist didn’t believe he had GCA even though he had PMR and all symptoms of GCA except vision loss. We weren’t about to wait around so I made call after call and was that squeaky wheel. Was able to finally get the doctor on the phone, while watching my husband going downhill very quickly. That’s when she said she didn’t think he had it. I pushed the issue hard and she finally (reluctantly) agreed to a temporal artery biopsy. Three days later we had an official GCA diagnosis. I knew immediately because the guy who did the biopsy said he saw inflammation in my husband’s artery. I called the doc again and she finally agreed to increase his prednisone. Unfortunately it wasn’t enough and we ended up in the ER with 3 days of 1200 mg of methylprednisolone IV infusions. I didn’t even know a person could take that much.
At the end of the day his doc who didn’t believe us now says he has the most severe case of GCA she’s seen. She thought he might have cancer and fortunately that has been ruled out.
We have an appointment with the chief of rheumatology. If we like her we’re changing doctors. His current one could have cost him his vision or even his life.
I’m so sorry to hear you’ve had relapses. My husband was diagnosed with PMR in May 2023 and GCA in February 2024. He’s on prednisone (80 mg due to his case being severe and resistant to treatment initially) and also started Actemra injections this week. I’m really hoping he doesn’t get relapses because his GCA already landed him in the ER. This has been so frightening especially the day I saw his temples start swelling. I wish you the very best and hope this 3rd relapse will be your last.
Wow! I didn’t know a person could have GCA without symptoms.
That was not our experience. My husband developed PMR in May 2023 and was put on prednisone. While still on prednisone, a lowered dose (12.5 mg from 30 mg when first diagnosed) he developed jaw pain, headaches and neck pain, scalp tenderness, face swelling etc. In Feb 2023. His rheumatologist didn’t believe he had GCA. I had to push the issue to get a temporal artery biopsy which turned out to be positive. He has the worse case his doc has seen and is now on 80 mg prednisone per day and Actemra. He also landed in the ER where he got 3 IV infusions of very high doses of steroids.
I read your response and wanted to let you know my husband was on 12.5 mg prednisone for PMR when he developed a very severe case of GCA.
From our experience I would recommend at least 40 mg if you develop symptoms of GCA - headaches, jaw pain, tender temples, tender scalp, loss of appetite were my husband’s symptoms. He had to be put on 80 mg but he has a severe case. I’ve read 40-60 mg is what is typically given for GCA. Then you’d need to get a temporal artery biopsy to confirm a diagnosis of GCA. Hopefully you won’t get it.
I hope and pray I don't develop GCA, but it seems quite common in people who have PMR. At least I know what symptoms to watch out for. I don't have a rheumatologist but my GP asked me when I first saw him for my PMR symptoms if I was also having any headaches, so he must be aware of the possibility of GCA.
I know it’s been a while since your post but my advice to anyone with symptoms of Giant Cell Arteritis (GCA) go to an emergency room and let them know what you suspect you might have. If we’d known this we could have saved a lot of time and aggravation. In the end my husband ended up in the ER which is where we got the most tests taken and the best treatment. His rheumatologist didn’t want to believe he had it. Not sure why since he had all the symptoms other than vision issues.
To isabelle7,
Wow, thankfully he had you as an advocate and I'd fire your rheumatologist ASAP. Thank you for letting us all know. I will be having a strong talk with mine.
