Gwyneth paltrow gets back to being talked about. The actress, according to what the Daily Mailsaid she had undergone a controversial wellness treatment to «remove toxins» and deal with chronic ailments: the therapeutic plasmapheresis. And she explained that she underwent five sessions in Chicago it cost her 50 thousand dollars. But what is it really? plasmapheresis? How does it work? And above all: what is it for, according to science?
What is therapeutic plasmapheresis
There plasmapheresis it is an apheresis procedure, i.e. a technique that allows a specific component to be separated and removed from the blood. With this technique, plasma is collected, the liquid part of the blood that contains proteins, antibodies, clotting factors and other dissolved substances. But we must distinguish, because there are two different types of plasmapheresis. There is it productive plasmapheresisa type of donation that involves the collection not of all the blood but only of the plasma. And then, there’s the therapeutic plasmapheresisthe one to which Gwyneth Paltrow underwent.
This second type of plasmapheresis, explains theHigher Institute of Health on the internet page dedicated to plasmapheresis«is carried out on the sick» and has «four main “therapeutic” objectives: remove cells and/or molecules from the blood of the person who undergoes it, replace a substance in case of deficiency or remove a constituent that can cause disease, modulate cellular functionality, collect non-pathological cells for manipulation for therapeutic purposes”. And also the MSD Manual for Professionals clarifies that it is a procedure used to remove pathological antibodies, immune complexes or other plasma proteins implicated in certain diseases. In other words, it is not a generic “detox” treatmentbut a technique with precise clinical indications.
How therapeutic plasmapheresis works
From a technical point of view, the blood is taken through a venous access and passed into a cell separator. The car divides plasma from blood cells (red blood cells, white blood cells and platelets). At this point, explain theISS«in the most commonly used therapeutic procedure (plasma-exchange), in each single session 1 to 1.5 volumes of plasma are removed». The volume of removed plasma «can be replaced with plasma derived from donations or with other replacement fluids (for example, albumin)”. According to what the portal reports Nurse24 the procedure can last from one to three hours and requires constant clinical monitoringbecause it can lead to side effects such as hypotension, allergic reactions or coagulation disorders. In short, it is a complex medical procedure, which must be carried out in a healthcare environment.
What it’s really for: medical indications
The recognized indications of therapeutic plasmapheresis they are mainly linked to autoimmune or hematological diseases. According to theHigher Institute of Healththe technique is used, for example, «in hyperviscosity syndrome caused by the excessive production of para-proteins (abnormal proteins) as occurs in multiple myeloma and in Waldestrom’s disease.”
And, again, in autoimmune-based diseases «such as myasthenia gravis and Guillain Barré syndrome.” And finally in syndromes of thrombotic microangiopathies, i.e. “occlusive disorders of small vessels (vascular microcirculation) characterized by anemia and a decrease in the quantity of platelets”. However, it is not recognisedin the official guidelines, as an anti-aging therapy or as a general tool to “cleanse the blood of toxins” in healthy people.
Plasmapheresis and anti-aging: what the research says
In recent years, some research has explored the idea that removal of plasma components may have effects on inflammation and biological aging. A study published in GeroScience in 2022 analyzed the effects of therapeutic plasma exchange on markers associated with aging, suggesting possible changes of some biological parameters.
On the contrary, however, according to research published on Scientific Reports in 2024 plasmapheresis increases markers of age acceleration when practiced without albumin replenishment. In general, in short, For now, scientific evidence is lacking who demonstrate a benefit in undergoing therapeutic plasmapheresis from a detox perspective as in the case of Gwyneth Paltrow.
