Pure blood is the key to health

Normally, blood is an exceptionally successful find of evolution; it nourishes the body and supplies it with oxygen, maintains a bond between organs with each other. When harmful substances enter the bloodstream, the whole body suffers. Fortunately, the blood is designed so that it can be cleaned of everything dangerous and unnecessary. There are a number of technologies that allow this to be done - extracorporeal treatment methods (EML). Over 80 pathologies are treated using EML, including atherosclerosis, coronary heart disease, allergies, bronchial asthma, gout, rheumatoid arthritis, chronic hepatitis, multiple sclerosis, psoriasis, diabetes mellitus and many others. For many patients, EML is the only way to live a full life. About how this works, we asked the head of the Center EML MEDSI, Ph.D. Vadim Leonidovich Averkiev.

The center was created by a professor, MD Konovalov Gennady Alexandrovich, the center has been using modern extracorporeal blood purification technologies for more than 30 years.

What is blood and why is it needed

In the body of an adult from 4 to 6 liters of blood. It constantly circulates through the body and carries oxygen and nutrients - this is its main task. In addition, nutrient proteins, fats and carbohydrates travel with blood, which cells use to generate energy and build new proteins; and signaling substances - for example, hormones that tell the body how to behave in different situations. An important part of the blood is the elements of the immune system: antibodies that recognize poisons and viruses, and cells that are engaged in the destruction of everything that the body considers harmful. Normally, blood is an exclusively useful part of the body, but it remains only as long as it has a healthy balance of components and no harmful agents. Pathogenic and toxic substances can come from the environment (viruses, salts of heavy metals and other poisons), and form directly in the human body (autoantibodies, circulating immune complexes, etc.).

From antiquity and until recently, sick blood was "poured" out of the body, bloodletting is now used in medicine, but only in healthy people as a donation for obtaining whole blood, followed by the isolation of components. The discovery of red blood cells and other components of the blood, as well as progress in the field of biochemistry, physiology and immunology over the past hundred years have allowed not only to "drain" the sick blood, but to cleanse it and return it to a healthy body. This process refers to extracorporeal (that is, occurring outside the body) methods of treatment (EML), or in another way - methods of therapeutic apheresis (removal). There are a lot of them, and they help fight many diseases - from allergies to cancer. EML allows you to remove from the circulatory system allergens, fractions of "bad" cholesterol, toxins, pathogenic antibodies and other substances that interfere with the normal functioning of the body.

How to clean the blood

Under normal conditions, the immune system copes with antigens (allergens, viruses), and the liver, our largest gland, and the kidneys are a natural filter to clean the blood. But it happens that the body does not cope on its own - and then medical technologies for blood purification come to the rescue.

To cleanse the blood of harmful elements, it must first be divided into components. Blood - this is 60% of plasma and 40% of the formed elements: red blood cells, oxygen-carrying, platelets, covering the place of rupture of blood vessels, and white blood cells, agents of the immune system.

In order to purify the blood, it is removed from the patient’s body to the external circuit of the bloodstream. First, the blood is separated in a centrifuge into plasma and cells. Then the plasma is sent to the filtration column, where the harmful elements are “sifted” (filtered), and the purified plasma and blood cells are reconnected and returned to the patient. The volume of treated plasma during the procedure is usually 1-1.5 of the total volume of circulating plasma.

There are various cleaning methods that differ in how the filter works. The choice of a filter depends on which substance needs to be removed from the body. Modern filters are highly selective: they "sift" only the target substance, allowing you to return beneficial plasma elements to the patient’s blood without loss.

"Catchers" of cholesterol

One of the most popular uses of EML is the purification of blood from “harmful” cholesterol. Cholesterol is an important substance for the normal functioning of the body; It is part of cell membranes, is involved in the metabolism of fats and hormones. It enters the body with food (a lot of it, for example, in egg yolks) and is produced in the liver. Blood transports it to the cells that need it. But cholesterol does not know how to travel through blood on its own: blood is an aqueous solution, and cholesterol does not dissolve in water. Therefore, carrier proteins are produced for the transport of cholesterol in the body, the complexes of which with cholesterol (lipoproteins) are highly soluble and can travel in the bloodstream - but only until there are too many of them. In excess, lipoproteins form plaques that impede the movement of blood through the vessels, which is very dangerous because it can lead to a heart attack or stroke.
