[Diagnosis and treatment of aquired aplastic anemia].

AIM: To analyse the results of diagnosis and treatment of patients with aquired aplastic anemia (AA) in one center. MATERIAL AND METHODS: All AA patients, diagnosed and treated in one clinic in 1998-2005, were included in the trial. In severe and very severe AA (SAA/VSAA) the patients (n = 19) received combined immunosuppressive therapy (IST) with antithymocytic globulin (ATG) and cyclosporin A (CsA), in non-severe AA (NSAA) the patients (n = 9) were given monotherapy with CsA. Allogenic transplantation of bone marrow (alloTBM) was made in 4 young patients with SAA/VSAA. RESULTS: The diagnosis of AA was established in 33 patients (19 males and 14 females): NSAA in 9, SAA in 19, VSAA in 5, idiopathic--in 26, posthepatic--in 5, associated with pregnancy--in 2 patients. Age median was 20 years (13-53). The clone of paroxysmal nocturnal hemoglobinuria (PNH) was identified in 7 of 33 patients (21%), antigen HLA-DRB1 *15 in 6 of 11 patients (55%). In median of 26-month follow-up 31 patients (94%) were alive. In IST, complete or partial remissions were obtained in 88% patients. Median of the interval to achievement of transfusion independence made up 2.5 months. All the patients after alloTBM are in complete remission, chronic extensive transplant against host reaction was observed in one case. CONCLUSION: Introduction of updated protocols provides long-term survival of more than 80% AA patients. To optimize treatment outcomes, it is necessary to include newly diagnosed AA patients into ongoing multicenter studies.

[Results of Befnorin clinical trails in healthy volunteers]. / Rezul'taty klinicheskogo ispytaniia preparata benforina na zdorovykh dobrovol'tsakh.

Clinical trails of Befnorin based on the human recombinant TNF-beta elaborated at the Research Design and Technology Institute of Biologically Active Substances, "Vector" State Research Center of Virology and Biotechnology, were carried out on healthy volunteers in compliance with a decision passed by the Committee of Medical and Immunobiological Preparations, Russia's Health Ministry. Single Befnorin doses of 5-10(4) U, 10(5) U, 5-10(5) U, and 10(6) U were administered as intramuscular injections. Clinical, biochemical and immunological parameters were registered for 7 days after a single dose. The drug had an impact on the below immunity indices: Fc-phagocytosis of monocytes, migration index and migration inhibition index. The dose of 10(5) U was proven to be most effective and safe. Supposedly, the drug can be effective in the treatment of herpetic diseases.
