2020 № 6 Blood collection during the period of COVID-19 infection
We searched Google Trends using terms in Russian and English: “coronavirus”, “blood transfusion”, “plasma transfusion”, “donate blood”. Object of study – requests submitted from February 15 to May 25, 2020 in the world, Russia and the USA. Anomalous increase in demand in the USA was revealed corresponding to the booming demand for plasma donors – convalescents of COVID-19: a) for “plasma transfusion” – March 30 – May 2, b) for “donate blood” March 17 – April 7. The studied Russian Google Trends indicators correspond to the reliable work of the blood service, which during the pandemic period solved the main task to provide hospitals with effective and safe components of donated blood. These data provide additional evidence of differences in the scientific validity of blood services in developed countries, and show that Google Trends can serve as a tool to track trends in blood donation.

2022 № 1 Irregular antibodies to red blood cells in patients of a multidisciplinary clinic
We studied the practice of transfusion therapy for patients at the Pirogov National Medical and Surgical Center, who
were diagnosed with irregular antibodies to red blood cells (RBC) in 2020. Among hospital patients, the part of such
immunized persons was 1,62% (200 people). Of these, the selection of donor RBC was performed in 29 (14,5%) patients.
45 cross-matching procedures were performed, which involved 177 units of RBC. 121 units were found compatible and
56 – incompatible. Of 29 patients with matched blood, transfusion of matched RBC was received by 14 (48,3%) people.
They received 54 units of RBC compatible in the indirect antiglobulin test. In 2 patients, antibodies were detected during
transfusion therapy. It is advisable to: a) create a centralized laboratory for federal medical organizations with the possibility of identifying irregular anti-RBC antibodies and individual selection of compatible donors; b) include identification of antibodies in the range of medical services; c) standardize the number of segments of the donor container tube from which RBC can be taken for cross-matching; d) establish the frequency of screening for irregular antibodies while continuing transfusion therapy; e) in a clinic of comparable scale, it is sufficient to maintain a daily supply of RBC in the amount of 2,1% – 2,8% of the annual consumption in order to provide an individual selection of blood for patients with irregular anti-RBC antibodies. -
2021 № 5 Error in the regulation of bacteria screening in donor blood components
We searched for standards for monitoring the sterility of donor blood and blood components. The legal nullity of the “Instructions for the control of the sterility of canned blood, its components, preparations, canned bone marrow, blood substitutes and preservative solutions” was established. For proper sterility control of donor blood and its components, the “Standard for equipping a blood transfusion station (blood center)” (approved by Order of the Ministry of Health of Russia No. 1167n dated October 28, 2020) needs to be amended by replacing the “Bacteriological analyzer for the identification of microorganisms” with “Analyzer of blood cultures“.

2020 № 9 Donor platelets collection in a pandemic of COVID‑19 infection
The work of the Samara Regional Clinical Blood Transfusion Station, the collection and delivery of platelet concentrates in
2018, 2019 and in the first 6 months of 2020 was assessed. The annual demand for platelet concentrates in 2019 increased by 22.9%, and in the first half of 2020 the issue of platelet concentrate decreased by 12.1%, which is associated with a change in treatment work during the period of infection COVID‑19. The proportion of platelets isolated from whole blood in the first half of 2020 decreased from 24.7% (the end of 2019) to 17.4%, (p <0.001). This maneuver made it possible to accept all donors wishing to donate apheresis platelets. -
2020 № 5 Blood collection during the period of COVID‑19 infection
We evaluated the work of the Samara Regional Clinical Blood Transfusion Station, the collection and delivery
of blood components in January-April 2019 and 2020 changes in activity at the beginning of the COVID‑19 pandemic
infection. The need for blood components decreased: red blood cells – by 16,7%, platelets – by 13,0%, plasma – by 25,6%, cryoprecipitate – by 32,5%. SOKPSK provides the needs of the region’s healthcare in blood components and preparations, as well as the safety of donors and staff. For this: a) new donor recruitment methods have been introduced; b) plasma donors have been transferred to blood and platelet donors. A common pattern is the reduction in the use of medical technologies that require transfusion of blood components. According to the results of the first 4 decades of work, such a reduction in the Samara region is two time less than in other developed countries. -
2013 № 5 Regarding methodology approaches in forming clinical-statistic groups when heart attack occurs (State Health Care Entity of Samara regional clinical cardiologic dispensary, Samara, Russia)
