[Blood transfusion support in rendering medical care in extreme conditions].

About 20% of accident and disaster victims need the hemotransfusion therapy. At present the method of erythrocyte long-term storage in the blood banks with glycerin high concentration is the most acceptable one. There are special medical teams (SMT) in the districts. They include the transfusiologic group with appropriate reserve of hemotransfusion materials. Most of them must be stored as untouchable reserve in the institutions of blood service and large hospitals on which the SMTs are based.

[Current problems in organizing the donor system in the Armed Forces].

In the work the factors, rendering essential influence on organization of donorship in modern army conditions are systematized. The organization of donorship should be connected to functioning of territorial system of medical maintenance of the Armed Forces of RF. It assumes presence of four organizational levels: central, district, zone and garrison. Perfecting the system of organization of donorship, we should be guided by the following conducting principles: maximum maintenance of safety of donorship; wide introduction of a method of plasmacytopheresis in work of establishments and subdivisions of blood supply service; organization of autodonorship and quota of the donors of an emergency reserve in each military-medical establishment; reliable maintenance of revealing of markers of hemotransmissible infections at inspection of the donors.

[The organization of the donation of autologous blood and its components in cardiac surgery].

The article analyzes an experience with the organization of autodonation of blood and its components in surgical treatment of 305 patients with congenital and acquired defects and ischemic heart disease. Methods of plasmacytapheresis and cryopreservation used at the terms from 3 days to 12 months before operation allowed storage of the autologous components of blood in 41.2% of the patients having indications for autodonation. In 29.1% of the observations the autotransfusion media were reserved under the outpatient clinic conditions which resulted in shorter terms of treatment at the hospital. The number of unfavorable reactions during the donation in patients did not exceed analogous parameters in regular donors. Autohemotransfusions 3-5 times reduced the volume of transfusions of the allogenic blood components and they were completely avoided in 20.1% of the patients.

[The immunogenetic status of patients with infectious endocarditis].

On the basis of a deep clinico-immunological examination of 23 patients with septic endocarditis it was established that HLA B35 antigen and haplotype A2-B35 are the most probable markers of the genetic predisposition to the development of infective endocarditis. Immune deficiency is accompanied by a decreased content of T-helpers, decreased activity of natural killers and phagocytic activity of granulocytes. A combination of a genetically determined defect of the immune response with a modification of histocompatibility antigens by infective agents, drugs (narcotics, antigens etc.) and other factors are thought to be of pathogenetic significance in the development of infective endocarditis.

[The histocompatibility problem in military blood transfusions].

One of the basic approaches which provides for the increase of immunological safety of hemocomponental therapy is the use of donor-recipient histocompatible blood. The decisive factor in the organism's individuality is HLA-antigen system. Antigen incompatibility of donor's and recipient's tissues in HLA-antigen causes the development of delayed hypersensitivity and sensibilization of the recipient, which provoke a number of complications and posttransfusion reactions. Histocompatibility is the key problem for modern transfusiology and transplantology.

[The problem of cytomegalovirus infection in military blood transfusions].

The actuality of a problem of cytomegaloviral infection in military transfusiology is substantiated by the increasing number of immunocompromised recipients, mass use of hemocomponent therapy in prophylaxis and correction of anemia, thrombohemorrhagic and immunodeficient syndromes. Cytomegaloviral infection in the recipients of hemocomponents may have unfavourable consequences, such as the development of mononucleosis, enhanced sensitivity to opportunistic infectious agents as a result of virus-induced immunodepression, graft rejection, risk of the development of oncologic diseases, atherosclerosis, disorders in the processes of reparation and regeneration. In the northwestern part of Russia the cytomegaloviral antigens are disclosed in 65-75% of men, age 18-23. Actual tasks are the following: put into practice cytomegaloviral antigens test for donors, make a wide use of effective leukocytic filters for leukocyte removal from hemotransfusional medium, minimize posttransfusion immunosuppression, determine recipients who need transfusions of hemocomponents prepared from seronegative donors.

[The hepatitis C problem in transfusions in military medicine].

The article contains data on viral hepatitis C, its etiological factor, epidemiology, methods of diagnosis and prophylaxis. It's high time to conduct 100% screening control of donors for viral hepatitis C antibody, using national test system of fermental analysis. The authors worked out the method of "dry drop" to study the serum for hepatitis C virus antibody.

[Specific and substitute markers of hepatitis C in screening donor blood].

The efficacy of specific and substitute markers of hepatitis C was compared in donor blood screening. 2615 blood donors were examined using two EIA kits for detection of HCV antibodies. The presence of nonspecific markers of non-A non-B hepatitis was also checked. 1.3% of the donors were found to carry HCV antibodies. This necessitates donor blood testing for anti-HCV antibodies using EIA. Such measure reduces three-fold the risk of the virus transmission with blood components and preparations. The preference should be given to more sensitive test systems of the second generation, whereas less sensitive, but more specific, test systems are more valuable for accurate diagnosis and treatment effects assessment in HCV infection. It would be appropriate to perform compulsory examinations for HCV infection in medical staff. This will entail efforts on development of the infection diagnostic verification criteria and preventive measures.

[Comparative characteristics of a test system for detecting antibodies to hepatitis C virus].

The sensitivities and specificities of enzyme immunoassay (EIA) kits for the detection of antibodies to hepatitis C virus (HCV) were compared in donor blood screening. A total of 3308 donors were examined using Akvapast immunodiagnosticum (St. Petersburg), lot 12. Anti-HCV antibodies were detected in 43 (1.3%) subjects. Blood sera of these donors were additionally investigated using other lots of Akvapast, Hepascan (Bioservice, Moscow), Blot-0.5 (Bioservice, Moscow), and immunoComb (France). The studies demonstrated that none of the agents used can be acknowledged as ideally sensitive and specific for the detection of anti-HCV antibodies. Maximally sensitive diagnostic kits should be preferred for the screening of donors of blood components and for other mass surveys. Highly-specific test systems are advisable for profound examinations and diagnostic monitoring. The creation of a system of reference and expert diagnosis of hepatitis C remains a pressing task.
