Dupuytrens contracture Improved with Rapamycin

Dupuytrens contracture softening. 7 degrees improved MCP extension in 10 days.

Similar effect with 5 day fast.

I have a relative with severe Dupuytren contractures. Are there any studies suggesting Rapa may help or a role for mTOR in Dupuytrens?

Only personal experience. I’ll update in a few weeks

Hi and welcome to the forum. Thanks for posting.

I’ve never heard of Dupuytren’s contracture - so added the wiki reference in your first post (as I suspect most people are like me in this respect).

Please keep us informed on how things go over the next few months with your personal trial.

I have it, but only in the mildest form; a nodule on the palm of my right hand below the ring finger.
My poor father had a severe case of it; he could only use his thumb and index finger of each hand. He was disallowed military service in WW2 due to it.
His aunt had it, too, so it definitely ran in our family.

Hi Eberkram. I am glad to hear that your Dupuytren’s improved. That’s great news. Could you please give me more information on what you did prior to the improvement?

Did it improve after starting rapamycin? If so, what dose did you take and how long had you been taking it when seeing the improvement? Did the nodules get smaller or did you just experienced reduced contractures and softer nodules?

As far as your mention of a 5 day fast. You mean you experienced similar improvements in the disease after a 5 day fast? If so was that a long lasting improvement or just something you tried recently? Have you tried fasting before? Have you tried shorter fasting without effects on Dupuytren’s in the past? Also mind sharing how old you are?

Please keep us posted on the progress. Thanks.

Good questions. I’m 67 yo.

I started 5 day fasts 4 years ago. Two a year. With my first one I noticed some softening of the palmar fascia and improved ring finger extension. I’ve always had the ability to hyperextend. -20 degrees. I improved from 0 degrees back to -10. That improvement got my attention. I’m a surgeon. Little things make a big difference.

Over the years the central cord of my palm has become more defined. More nodular in nature and with general tightening of my palmar fascia. I was back to 0 degrees. So not disabled by the standard, but I noticed it in surgery.

I started Rapamycin, 6 mg/week, 5 weeks ago. The softening was not noticed for about 10 days. Subsequently, The central cord has reduced in diameter and the rest of my palm is less tight with 5 finger extension. An ulnar lateral band on my middle finger has also softened. Clearly less tight.

I’m back to -20 degrees on my ring finger.

There have been no other changes in diet, activities, sleep, massage, or surgery schedule.

The two things in common with the fast and rapamycin is mtor inhibition.

I’m curious if there is other evidence of modified fibrotic response with rapamycin. I believe there is but I lack a reference.

There are many clinical situations where a myofibroblast inhibition would be clinically relavent. Maybe there is some senescence involved as well.

I would love to hear others experience and perspective.

Thanks for the detailed update! The improvements you report are quite remarkable given how hard Dupuytren’s is to treat usually. Back to -20 degrees, that’s a great improvement.

I agree with you on mTOR inhibition being an interesting factor here that is common with fasting and rapamycin treatment. There is certainly some evidence that mTOR activation can cause or exacerbate fibrosis. That makes for a potential connection with Dupuytren’s.

Best of luck and let us know if you see further changes in future.

I forgot to post this link to a study showing that mTOR activation may increase fibrosis.

Yes, I also read that mTOR activity is linked to fibrosis.
Cardiac fibrosis is thought to be a driver of atrial fibrillation, which is one reason why I started on Sirolimus.
