Plasmapheresis, also known as therapeutic plasma exchange (TPE), is a nonsurgical therapy that removes and replaces a patient’s blood plasma. Plasmapheresis involves removing blood through a needle or catheter and circulating it through a machine where the blood is separated into red cells, white cells, platelets and plasma. The plasma, which is the fluid content of the blood, is discarded and replaced with a substitution fluid (mainly albumin solution). The substitute plasma and the patient’s own blood cells (red cells, white cells and platelets) are returned to the patient through a return needle.

Note, I’ve heard from some people who have done the cycle of 6 treatments of plasma dilution at the Kiprov center. Here is what they are reporting:

By email, I have inquired about changes in DNAm-based bio-age from
a couple of people who have had Conboy-type plasma dilution by Dr.
Kiprov in San Francisco and have also done before-and-after Horvath-type
DNAm analysis. The observed improvement is at best 1-3 years, which is
in the noise. That’s only anecdotal, of course, but interesting.

and another person

I am one of those treated by Dr Kiprov. I have the same experience with
methylation age improvement as others after 6 treatments. Like you say, in
the noise.

I believe the benefits are short term, since the Conboy’s/Kiprov recommend
re-treatment (after 6 monthly treatments) at 3 month intervals. … [The] Kiprov/Buck Institute [is working} to determine treatment frequency as part of their latest apheresis trial.

See my attached methylation age vs treatment notes. Restarting apheresis
treatments after obtaining a GRIMage test baseline.

Not something I would want to subject myself to if the results are in the noise. Great thinking, but sometimes things just don’t work out and you need to move on to something else… Like Rapamycin.

The reality is most people could not afford the treatment’s.

Yes - especially at $6,000 per session. But I wonder if it might be doing things that are important and helpful, but not well-measured by the epigenetic age clocks yet.

I also wonder if at high volume (of customers) they might be able to bring down the cost significantly.

I also wonder if a combination - like these plasma dilutions, combined with a person taking rapamycin, might make the benefits last much longer (because of Rapamycin’s effect of stopping the aging of the blood stem cells, for example).

I think the reason Heterochronic Parabiosis works is that there is something that increases in the levels in blood over time that causes senescence. I think that something is IL-10. It is part of SASP and causes senescence through the Janus Kinase, NF Kappa B and SLC25A1,.

If you swap the plasma you will remove some IL-10, you may also remove other negative things and introduce a positive level of albumin, but it does not immediately stop the currently senescent cells from sending out more SASP.

I think it is possible to make senescent cells enter the cell cycle properly and work up to a point. That is better in many ways then senolytics because you don’t have to replace the cells even if they are not as good as cells which were not senescent in the first instance.

Hence I think this approach is marginally positive. If it was done for more sessions it would probably improve the outcome.

Let’s say you do 5 sessions at 6,000 a pop. That’s 30,000!!! I’d rather buy a sports car. I’d feel a lot younger too!

I don’t personally intend trying this, but there are people for whom it would be cost effective if it maintained their health at a good level.

Oddly enough when I looked for the evidence for IL-10 I found a masters thesis unpublished in any journal:

I couldn’t make this webinar - did anyone listen in, and was there anything new or interesting reported?

I saw your post too late to listen to the webinar. Nevertheless I appreciate your posting the paper here. I have signed up to be a participant in a random, placebo (sham aphaeresis) study that Dr. Kiprov is conducting, funded by Lyfspan Inc -(? couldn’t find them on google). I’m very curious and hopeful about this procedure but quite unsure as to whether I will go through with participating. I am leaning towards waiting until the results are in. Yes, it would cost a lot more than being in the study (if you are in the placebo group they give you actual treatment free post study) but it seems pretty intense if the results are mild to no improvement. The procedure replaces your plasma with saline and albumin and 2 immunoglobulins. I do hope it shows strong results!

I nearly choked on my tea over this. Hilarious but true.

One thought I did have about replacing blood plasma is that it may help remove the ‘forever chemicals’ and toxins from our blood that we cannot get rid of ourselves. PFAS chemicals are especially nasty.

The Conboy approach seems like a re-branding of blood donation to make a mint. Although it’s a bit different, it’s still quite similar. I will admit, plasmapheresis is probably more comprehensive than donation.

People need to be incentivized to donate blood. This saves others who need blood and actually helps those who donate to live longer. It’s a win win win situation.

I’ve tried to sign up for blood/plasma donation several times. But given my lower weight I’m not accepted.

Does it mean that plasma donation affects weight? What’s your weight/height if you don’t mind sharing. Mine is 5’4”, 111 lb. Was thinking about plasma donations.

Lara, they have specific restrictions around plasma donations just for the safety of the donor. I think the issue is the amount of plasma relative to the size of the person.

See here:

Donor safety, as well as the safety of the therapies made from plasma donations is of primary importance. You will need to visit a plasma collection center to determine if you are eligible to donate.
In general:

  • Plasma donors should be at least 18 years old
  • Plasma donors should weigh at least 110 pounds or 50 kilograms
  • Must pass a medical examination
  • Complete an extensive medical history screening
  • Test non-reactive for transmissible viruses including hepatitis and HIV
  • Follow a recommended diet including 50 to 80 grams of daily protein

Before donating plasma it is important to:

  • Drink plenty of water or juice to be fully hydrated
  • Notify center personnel if you have had recent surgery
  • Notify center personnel if you have obtained a tattoo or piercing within the past 12 months
  • Notify center personnel if you are taking medication or are under a doctor’s care for any medical condition
