Study of Efficacy and Safety of the Plasmapheresis Method With Albumin Compensation Compared With the Plasmapheresis Method Without Albumin Compensation for Aging Biomarkers Correction in Men and Women Aged 40 to 55 Years Old

Reaching active aging makes it important to implement new methods affecting the biological age of a person. Biochemical parameters of a blood test are aging biomarkers that are ones of the most accessible for testing. We know that, with age, there is increase in levels of LDL, triglycerides, homocysteine and other biomarkers relating the body state.

One of the initial approaches of anti-ageing therapy is detoxification, reocorrection and immunocorrection. Methods of extracorporeal hemocorrection showed good results in this area. For instance, the use of plasmapheresis is very effective during prophylaxis, treatment and rehabilitation after various diseases/injuries. The main effects of plasmapheresis are related to removal of endo- and exotoxins, including products of lipid peroxidation, and to draining effect as a result of a heavy flow of interstitial fluid containing products of pathometabolism into the blood stream within concentration gradient (by "dynamic equilibrium" in concentration of different substances in intracellular, interstitial and intravascular compartments). These effects are also related to release of receptors, their sensitization to their own neurohumoral regulation mechanisms, to insulin, in particular (as consequences, lower glucose tolerance, lower substrate glycation).

Thus, at this stage, experts assess effectiveness and organize data of existing prevention methods for premature aging and correction of aging biomarkers, as well as develop comprehensive programs for drug-free and pharmacological intervention. Introduction of the body detoxification method based on extracorporeal hemocorrection (developed in FGBU Russian Scientific Center for Medical Rehabilitation and Balneology of Ministry of Health of Russian Federation) may extend the range of effective and safe methods within such programs, as well as lower patients' biological age and, thus, lower risks of developing age-related diseases, decrease number of disability cases, which can contribute to life prolonging and improvement of its quality.

• plasma exchange with albumin (Procedure), also known as plasmapheresis with albumin: plasma exchange with albumin, two per week, 110% of the circulating plasma volume
• plasma exchange without albumin (Procedure), also known as plasmapheresis without albumin: plasma exchange without albumin, two per week, 110% of the circulating plasma volume

Primary outcomes

• Dynamics summary for improvement of aging biomarkers' values assessed by a patient's biochemical blood count [1 month]: Dynamics summary for improvement of aging biomarkers' values assessed by a patient's biochemical blood count at visit 6, compared with initial values (visit 0).

Secondary outcomes

• Dynamics summary for improvement of aging biomarkers' values assessed by a patient's biochemical blood count [17 (+/- 2) days]: Dynamics summary for aging biomarkers' values assessed by a patient's biochemical blood count at visit 5, compared with initial values (visit 0).
• Dynamics summary for aging biomarkers' values assessed by a patient's complete blood count [1 month]: Dynamics summary for aging biomarkers' values assessed by a patient's complete blood count at visits 5 and 6, compared with initial values (visit 0).
• Dynamics summary for aging biomarkers' values assessed by a patient's blood serological test [1 month]: Dynamics summary for aging biomarkers' values assessed by a patient's blood serological test at visits 5 and 6, compared with initial values (visit 0).
• Dynamics summary for aging biomarkers' values assessed by a patient's coagulation test [1 month]: Dynamics summary for aging biomarkers' values assessed by a patient's coagulation test at visits 5 and 6, compared with initial values (visit 0).
• Dynamics of results according to the method of "phenotypic age" [1 month]: Dynamics of results according to the method of "phenotypic age" assessment with the use of values of complete and biochemical blood counts at visits 5 and 6, compared with initial values (visit 0). An assessment of the "phenotypic age" will be carried out (Morgan E. et al., 2018). For counting, 10 markers are used: albumin, creatinine, glucose, C-reactive protein, percentage of lymphocytes, average cell volume, distribution width of erythrocytes, alkaline phosphatase, leukocyte count, chronological age.
• Dynamics of results according to the method of biological age [1 month]: Dynamics of results according to the method of biological age assessment with the use of values of complete and biochemical blood counts at visits 5 and 6, compared with initial values (visit 0). The biological age will be assessed by the method of Putin E., Mamoshina P. et al., 2016. The following markers are used for calculation by this method: albumin, glucose, urea, cholesterol, total protein, sodium, creatinine, hemoglobin, total bilirubin, triglycerides , HDL cholesterol, LDL cholesterol (Friedewald), calcium, potassium, hematocrit, MCHC, MCV, platelets, erythrocytes (erythrocytes), weight, height. An online system available at http://www.aging.ai will be used to estimate biological age.
• Dynamic pattern according to ECG results [1 month]: Dynamic pattern according to ECG results in 12 leads at visits 5 and 6, compared with initial values (visit 0).
• Dynamic pattern according to results of vascular ultrasonography [1 month]: Dynamic pattern according to results of vascular ultrasonography at visits 5 and 6, compared with initial values (visit 0).
• SF-36 scale [1 month]: Change of scores according to every scale out of all 8 scales from the SF-36 questionnaire at visits 5, 6 and 7, compared with initial values (visit 0).
• HAM questionnaire [1 month]: Dynamics of subjective assessment of a patient's current psycho emotional state (HAM questionnaire) at visits 5, 6 and 7, compared with initial values (visit 0). The Hamilton Rating Scale for Depression (HRSD), also called the Hamilton Depression Rating Scale (HDRS), abbreviated HAM-D, is a multiple-item questionnaire used to provide an indication of depression, and as a guide to evaluate recovery.
• scales of the "Health-Promoting Lifestyle Profile" [1 month]: Change of scores according to every scale out of 6 scales of the "Health-Promoting Lifestyle Profile" questionnaire at visits 5, 6 and 7, compared with initial values (visit 0).
