Electron microscopic pictures of track membrane
Membrane plasmapheresis is based on the use of track
membranes
Track membrane is a thin polymeric film with through pores. It is produced by
physicochemical treatment of a lavsan film irradiated with accelerated charged
particles of the inert argon gas.Characteristics of the track membrane:- pore diameter - within the range of 0.4
microns,- thickness - 10 microns.
Membrane plasmapheresis
Device and plasma filter created by constructers of our company are designed for performing therapeutic and donor membrane plasmapheresis.
Therapeutic plasmapheresis is one of the methods of efferent therapy aimed to eliminate various pathologic elements (autoantibodies, immune complexes, natural metabolites, toxic substances of exo- or endogenous origin) from the organism.
Therapeutic plasmapheresis is used with high efficiency in prevention of occupational and autoimmune diseases, therapy, oncology, obstetrics and gynecology, perinatology, and pediatrics, in cases of mass poisoning, in treatment of drug and alcohol abuse, prevention of premature aging, strengthening of reproductive health.

The main plasmapheresis effects DETOXICATION • elimination of toxic substances• activation of natural detoxication systems of organism
BLOOD RHEOLOGY CORRECTION • reduction of blood viscosity • increase of blood cells’ deforming• reduction of cell conglomerates’ formation, vasodilatation
IMMUNOCORRECTION• elimination of antigens, antibodies, circulating immune
complexes• activation of immune system • changing of immune response
INCREASE OF SENSITIVITY TO ENDOGENOUS AND DRUG SUBSTANCES
• Efferent treatment methods are widely used for restoration of disturbed homeostasis. Particular importance in functioning of organs and systems has a constant composition of the liquid base of body - tissue fluid and blood. Disturbance of individual organs’ function will inevitably entail changes in blood and disturbance of physiological processes of other organs and systems.
DETOXICATION• Elimination of exo- and endotoxins
(med.preparations, chemical agents, Escherichia coli endotoxin, inflammatory mediators, ferments, hormones, products of free radical oxidation), blood cells deplasming
• Increase of antioxidant defense factors activity due to exit from the blood cells and decrease of free radicals concentration, reduction of regulatory substances number below the critical level
• Break of existing vicious circles, improvement of functional detoxification system - a manifestation of “deblocking" procedures effect
Rheocorrection
• Decrease of blood viscosity, increase of erythrocyte deformability, transcapillary exchange, improvement of microcirculation, oxygen delivery to tissues, normalization of tissue metabolism
Immunocorrection
• Activation of nonspecific resistance. Increase of serum bactericidal activity, content of complement, lysozyme, functional activity of phagocytic system with increase of phagocytic index and phagocytic number of neutrophils, normalization of leukocytes’ spontaneous migration
SURGERY
• Application Before, Inter, and Post surgery for the following indications:
Adequate inflammation. Good healing.
Survival of flaps.Decrease cardiovascular risk.
Decrease edema.
ALERGIES
1. Diathesis in children:- atopic dermatitis;- neurodermatitis;- eczema;- Lyell's syndrome.2. Hay fever:- rhinosinusopathy;- Hay fever;- conjunctivitis.3. Bronchial asthma.4. Allergic vasculitis:- Cherga-Strauss syndrome;- Wissler-Fanconi subsepsis.5. Anaphylactic shock.
PSORIASIS
Plasmapheresis (PA) in psoriasis is indicated in the first place to patients suffering from universal affection of the skin - erythroderma, as well as exudative form of the disease.Besides, PA should be applied as additional method in case of insufficient efficiency of traditional therapy of psoriasis, as well as in torpid course of the disease.
CRITERIA OF EFFICIENCY
• Reduction of infiltration in the zone of plaque and the subsequent resolution of eruptions
• Increase of the quantity of T-lymphocytes• Stimulation of phagocytizing activity of neutrophils• Elimination of CIC from blood

PLASMAPHERESIS IN THE THERAPY OF ATOPIC DERMATITIS
• Congenital breaches of reactions of cellular immunity in atopic
dermatitis are closely connected with blockade of beta-adrenoreceptors. As a result of this, the processes of releasing of mediators from fat cells and basophiles are intensified, which brings about suppression of the function of Т-lymphocytes.• The defect of Т-suppressors provokes elevated production of
IgE in response to antigenic stimulatio.• Plasmapheresis (PA) breaks this vicious circle through
deblocking of beta-adrenoreceptors and mechanical removal of excess of IgE.
INDICATIONS IN ATOPIC DERMATITIS
• Plasmapheresis is indicated as additional method in combined therapy to patients with severe, disseminated atopic dermatitis of long and torpid evolution, including in its erythrodermic form.
CRITERIA OF EFFICIENCY
• Reduction of the level of IgE (after 48 hours there is registered an increase of its concentration, but in repeated PA procedures
the level of IgE falls considerably).• Reduction of the level of circulating immune complexes.• Stabilization of the pathological process, cessation of the itch,abrupt reduction of edema and hyperemia.• Regression of acute manifestations of the disease, partial or
complete resorption of the infiltration.

PLASMAPHERESIS IN THE THERAPY OF ROSACEA
• The etiology and pathogenesis of rosacea are
polydimensional. Due to this circumstance the range
of methods of therapy of this disease is wide.
However, the available data about the influence of
endogenic irritants, such as bradichinin, calikrein,
circulating immune complexes, different toxins, allow
to a certain extent to consider plasmapheresis ( PA)
as pathogenetic method of treatment of rosacea.
INDICATIONS IN ROSACEA
• Plasmapheresis is indicated in torpid forms of
the disease, resistant to traditional methods of
treatment.
CRITERIA OF EFFICIENCY
Regression of eruptions Long-lasting remission

PLASMAPHERESIS IN THE THERAPY OF FOCAL SCLERODERMA
• Special role in the pathogenesis of the disease is
played by autoimmune reactions
INDICATIONS
The success in the application of plasmapheresis (PA) in this form of the disease as well as in case of a systemic process is explaned by removal of antibodies and inhibition of their syntheses
CRITERIA OF EFFICIENCY
Cessation of progression of the skin affections Improvement of the mobility of the joints

PLASMAPHERESIS IN THE THERAPY OF
ACUTE EPIDERMAL NECROLYSIS (LYELL’S SYNDROME)•What plays a leading role in the pathogenesis of this disease is
the allergic reaction, which by its gravity yields only to anaphylactic shock.•Important role is played by immune mechanisms, in particular, thecytotoxic action on the cells of the epidermis, accompanied by toxic manifestation of idiosyncrasy on the part of epidermal cells todifferent agents.
INDICATIONSThe application of the eliminating effect of plasmapheresis (PA)depends on the etiological variant of the Lyell’s syndrome - infectious, medicinal, toxic-allergic or idiopathic.
CRITERIA OF EFFICIENCY
Epithelization of the focci of affectionControlling of the symptoms of intoxication

What is removed from blood after membrane plasma filtration?
Substance Pathogenic influence
lipoproteins of low and very low density
so-called “bad” cholesterol, which is responsible for atherosclerotic plaques formation
Triglycerides their excess is usually associated with lipid, i.e. fat metabolism
fibrinogen and its breakdown products thrombogenic factors
factor Villebranta, C1 and C3 complement components
substances accompanying damage of vessels’ inner lining in various vasculitis, diabetes
Immune complexes
connection of antibodies to the antigen, bacteria “fragments” migrating in the body for a long time and settling on the kidney tissue, vessel walls, contributing to the formation of autoimmune reactions
immunoglobulins, including cryoglobulins, and antibodies
modified immunoglobulins, including autoantibodies, contributing to development of autoimmune diseases, damage of own tissues, obstruction of capillaries, etc.
fibronectin in excess contributes to cell adhesion
Prospective directions
• Today using a complex of hemapheresis, quantum blood treatment, ozone therapy, cascade plasmapheresis methods is considered to be prospective
UPDATES
• The use of autologous platelet-poor plasma (PPP) dates from 80 in the U.S., by and bypass machines as a byproduct of multicomponent apheresis, separated the components of the patient's blood and now employ through membrane filters (NANOTECHNOLOGY) during surgery as a hemostatic or adhesive gel, rich in fibronectin, Von Willebrans factor, vitronectin, thrombospondin and other adhesive proteins
