“…The risk of recurrence of thrombosis in relation to the OR was 2 or more times higher compared to ELISA [for IgG aCL (OR = 21.00 vs. OR = 10.33, respectively) and for IgG anti-β 2 -GPI (OR = 32.00 vs. OR = 7.50, respectively)]. Higher OR in aPL studies by ELISA is most likely related to their more frequent detection by CLA compared to ELISA [14]. This is due to the advantage of the CLA method in high analytical sensitivity and performance, a wide range of detectable concentrations while maintaining high accuracy in any part of the calibration curve.…”

Aim: The study aims to evaluate the incidence of recurrent thromboses in patients with primary antiphospholipid syndrome (PAPS) and its association with the presence of different antiphospholipid antibodies (aPLs) and known thrombogenic risk factors. Methods: This retrospective study included 52 patients. The median age of the patients was 38.5 years [31.5; 43.5], and the duration of the disease was 9.0 years [3.1; 13.0]. aPLs, including IgG/IgM/IgA antibodies to cardiolipin (aCLs), IgG/IgM/IgA anti-beta2-glycoprotein I (anti-β2-GPI), IgG anti-domain I-β2-GPI (anti-β2-GPI DI) antibodies, IgG/IgM antibodies to the phosphatidylserine/prothrombin complex (aPS/PT), and other thrombosis risk factors were included for analysis. Results: Recurrent thrombosis was reported in 34 (65%) out of 52 patients and 18 (35%) did not have it. The main reason for the recurrence of thrombosis was the lack of anticoagulant therapy: in 18 (52.9%) out of 34 patients with recurrent thrombosis. Three patients were taking warfarin at the time of thrombosis recurrence, but target international normalized ratio (INR) levels were not achieved. Other patients with recurrent thrombosis were taking direct oral anticoagulants (DOACs). The risk of recurrent thrombotic events with positive IgG aCL was 10.33 (P = 0.002) and 21 (P = 0.007) times higher were examined in enzyme-linked immunoassay (ELISA) and chemiluminescent assay (CLA), respectively. The risk of thrombosis was 4.58 times higher in patients who were IgA aCL-positive (P = 0.01). Compared with other antibodies, with positive IgG values of anti-β2-GPI and IgG aPS/PT by ELISA, a lower probability of thrombosis recurrence was observed: 7.56 and 7.25, respectively. A high risk of recurrent thrombosis [odds ratio (OR) = 32.0] was observed in IgG anti-β2-GPI (CLA). The combination of IgG aCL with IgG anti-β2-GPI and with IgG anti-β2-GPIDI is more informative with respect to the risks of thrombosis recurrence compared to double positivity for aCL with anti-β2-GPI (OR = 20.71 vs. OR = 10.18). Triple positivity for IgG aCL with IgG anti-β2-GPI and with IgG aPS/PT also shows better results compared to positivity for aCL with anti-β2-GPI (OR = 6.06 vs. OR = 5.79). Among other risk factors, arterial hypertension (AH) and obesity were significant in relation to the recurrence of thrombosis. AH occurred in 22 (42%) of 52 patients with PAPS. AH was associated with recurrent thrombosis in PAPS patients: 18 (53%) out of 34 with recurrent thrombosis had AH versus 4 out of 18 without recurrent thrombosis (P = 0.003). Conclusions: Recurrent thrombosis in antiphospholipid syndrome (APS) is largely associated with IgG aCL, IgG anti-β2-GPI, IgG anti-β2-GPIDI, IgG aPS/PT, and IgA aCL positivity. AH was a significant risk factor for recurrent thrombosis.

Antiphospholipid syndrome is a systemic autoimmune disease, the main part of pathogenesis of which is induc-tion of an inflammatory and procoagulant state in cells, thrombosis of venous and/or arterial vessels and, as a consequence, pregnancy complications. [4] Despite the long-term study of this pathology, the mechanism of its development is still not fully understood, what makes it more difficult to diagnose, prevent and treat this disease and to assess the risks of its complications.

Physical rehabilitation, by the foot method of body systemic mobilization, is a new medical technology. In connection with the current global unstable infectious situation, the need arose again to return to the question of finding and developing a systematic approach of simple and generally available physical methods. Aim. Analyze and evaluate the effect of the method of systemic mobilization of the body with the foot on the immune system of the human body, in order to prevent and rehabilitate post-infectious conditions. Material and methods. The research was carried out in various climatic zones. The procedures were based on the techniques of the first, second and third orders, in the second and third age groups. The first group consisted of patients of the second age group (13-60 years old). The second study group was represented by the third age group (60 years +). Materials of the first age group (up to 13 years old) were not submitted to the analysis. The method of exposure stipulated only the canonical motion direction in the selected sessions, the session lasted within 40-70 minutes, every day, for 10-30 days, taking into account weight, age and chronic diseases. 237 male and female patients’ material was reviewed and analyzed. Results and discussion. The method of systemic mobilization of the body exposed to the foot showed more significant positive results in the second age group - 92.8% and less in the third – 78.6% . To achieve positive results, it took more procedures 4 ± 1.0 in a humid climate compared to a dry one. It has been approved that accelerated blood flow in the main and collateral vessels triggers the activity of the lymphatic system. In the primary lymphoid organs, the hematopoietic function is restored and increased, optimizing lymphopoiesis and the state of lymphodynamics. Techniques of the first order (level) restore the flow of lymph through the superficial lymphatic vessels, collecting and producing outflow of lymph from the skin, subcutaneous tissue, superficial fascia and the surface layer of muscle fibers.Techniques of the second order (level) affect the lymph flow of deep lymphatic vessels, collecting lymph from muscles, joints and bones, producing outflow from deeply located tissues, lymphatic vessels lying along the arteries and veins of the same name, actively anastomosing with a network of superficial lymphatic vessels. Techniques of the III order (level) promote lymph flow through the lymphatic capillaries, from intra- and extra-organ lymphatic vessels, trunks and ducts. These techniques create conditions for accelerating drainage in the thoracic duct, producing an “emptying” effect by a direct physical coercion on the vertebral column, penetrating deeply. Conclusion. This method has statistically confirmed studies that indicate its ability to significantly increase the speed of blood flow in the main and adjacent vessels. The method can be considered as having a positive effect on lymphodynamics, in particular on lymphatic capillaries emanating from intra- and extra organ lymphatic vessels, trunks and ducts. By increasing the transport function of the lymphatic vessels, providing a full blood supply (nutrition) to the primary organs of the lymphatic system, exerting a stimulating effect on the spirally oriented lymphangion myocytes, in a soft and carefully worked out way, the foot method of systemic body mobilization creates optimal conditions for the correction of the immune system. Thus, it is able to protect the internal environment of the human body from foreign agents.
