[Oxidative stress and post-stroke depression]. / Okislitel'nyi stress i postinsul'tnaya depressiya.

OBJECTIVE: To study the use of combination therapy for post-stroke depression using antidepressants and antioxidants. MATERIAL AND METHODS: The dynamics of the clinical status of post-stroke depression and parameters of oxidative stress were evaluated in 60 patients with post-stroke depression before and after a 3-month treatment with fluvoxamine in a daily dose of 100 mg per day and cytoflavin in a dose of 10 ml/day (200 ml of 5% glucose solution or physiological saline in patients with diabetes mellitus) intravenously in the morning for 10 days followed by transfer to tablet form (2 tabs in the morning and 2 tabs in the evening for 90 days). RESULTS AND CONCLUSION: The results on the comparative effectiveness of the treatment of post-stroke depression with fluvoxamine monotherapy and the combination of fluvoxamine and cytoflavin confirmed the great effectiveness of the combination therapy, which should be taken into account when developing new treatment regimens for post-stroke depression, and the need for prescribing antidepressants and antioxidant drugs should be determined based on an individual assessment of the severity of depressive disorder and parameters of oxidative stress: endogenous antioxidant activities in each individual patient with ischemic stroke.

[Perspectives of treatment of patients with ischemic stroke: the place and the role of cytoflavin].

Based on complex clinical-biochemical studies of 60 patients after ischemic stroke (on average 2,4+/-0,3 years from the disease-onset), we showed the disturbance of balance between anti- and prooxidant systems. The changes in the parameters of oxidative stress were revealed as follows: the reduction in the activity of antioxidant defense markers (superoxiddismutase, catalase, oxidized and reduced glutathione), as well as in the spontaneous and induced hemoluminescence, the increase of malonic dialdehyde, a final product of lipid peroxidation. The changes in biochemical parameters were correlated with the severity of ischemic stroke consequences, assessed by the Rankin scale and the Barthel index. This finding points out the necessity of including antioxidants in the rehabilitation treatment. The effect of antioxidant drugs on the consequences of ischemic stroke was studied using cytoflavin (10 ml in 200 ml of 5% glucose solution daily intravenous in drops during 10 days) and cortexin (10 mg in 2 ml of 5% novocaine solution daily intramuscular during 10 days). The results revealed a higher effect of cytoflavin that was supported by the data of clinical-biochemical blood analysis: the level of components of glutathione system and catalase was significantly (p<0,05) increased in patients with sensory-motor disturbances and cognitive disorders thought did not reach the levels of control group.

[A trial of using allogeneic bone marrow transplantation in children with different hematologic neoplastic diseases]. / Opyt primeneniia allogennoi transplantatsii kostnogo mozga u detei s razlichnymi onkogematologicheskimi zabolevaniiami.

AIM: To define optimal time for transplantation of bone marrow (TBM) in children with hematological malignancies. MATERIALS AND METHODS: 20 allogenic TBMs were performed in children with acute myeloblastic leukemia (6 patients, 2 of them in recurrence), acute lymphoblastic leukemia (7 patients, 4 of them in recurrence), chronic myeloid leukemia (CML) in a chronic stage (3 patients), severe aplastic anemia (3 patients), generalized neuroblastoma (1 patient). Pretransplantation preparation included cyclophosphamide and busulphane or cyclophosphamide, busulphane and vepezide. The graft-versus-host reaction (GVHR) was prevented with cyclosporin A plus methotrexate or cyclosporin A plus urbazone. Engrafting was recognized by change of karyotype and blood group. RESULTS: From 13 children with acute leukemia subjected to TBM in a complete remission 4(33%) are alive, 5 died within 100 days after TBM (TBM was made in recurrence in 4 children), 3 patients died of recurrence 12 months after TBM. One patient with CML and one with severe aplastic anemia remain in remission. The main complications and causes of death in early posttransplantation period were hemorrhagic syndrome, infectious complications, GVHR. According to a one-year follow-up, the recurrent disease caused death most frequently. CONCLUSION: Positive result of TBM is related to the disease stage at transplantation.
