[Treatment of idiopathic thrombocytopenic purpura in adults: efficacy of domestic intravenous immunoglobulin in immune thrombocytopenia]. / Lechenie idiopaticheskoi trombotsitopenicheskoi purpury u vzroslykh: éffektivnost' otechestvennogo immunoglobulina dlia vnutrivennogo vvedeniia pri immunnykh trombotsitopeniiakh.

AIM: The study of effectiveness of intravenous immunoglobulin (IVIG) in therapy of idiopathic thrombocytopenic purpura (ITP) in adults. MATERIALS AND METHODS: High doses of IVIG (0.2-0.4 g/kg b.w. for 4-6 days) were given to 6 female patients aged 20 to 59 years (median--39 years) with immune thrombocytopenia. 4 patients had primary ITP resistant to glucocorticosteroids (GCS) and 1 female had chronic ITP treated by splenectomy without effect. 1 patient with rheumatoid arthritis developed severe thrombocytopenia combined with agranulocytosis when treated with nonsteroid antiinflammatory drugs. RESULTS: The response was observed in 5 of 6 patients (in 4 patients resistant to GCS and 1 RA patient). In 3 of them the effect was rated as excellent (platelets level > 150,000 per cubic millimeter), in 2 patients it was good (platelets count from 50,000 to 150,000 per cubic millimeter). Splenectomy was performed in 4 cases with ITP on day 8-14 after IVIG therapy. The 2- and 6-month follow-up evidenced for good results of the surgical treatment. The RA patient showed a stable rise of the blood count. Serious side effects of IVIG therapy were not registered. CONCLUSION: IVIG of Russian produce is effective in the treatment of drug-induced thrombocytopenia and ITP resistant to GCS.

The authors present the results of analyses of 425 samples of the cerebrospinal fluid from 67 patients with acute leukemia and from 30 ones with chronic myeloleukemia, carried out by the sedimentation method. This method permits concentration of the cells on a small site of the slide, involving the minimal injury to the cells, and thus helps obtain the cellular picture of the liquor, available for morphologic analysis. Detection in the sedimentation preparations with normal parameters of liquor cytosis of the blast cells in patients with acute leukemia and of the entire spectrum of maturing granulocytes with blasts in chronic myeloleukemia patients permits the diagnosis of the preclinical stage of neuroleukemia and thus helps detect the patients, for whom all the measures, included in the neuroleukemia prevention program, are absolutely obligatory and whose cerebrospinal fluid cellular composition should be regularly checked up.

The investigation of cell composition and different biochemical parameters (ceruloplasmin, lactate dehydrogenase, aldolase, ferritin, beta-2-microglobulin) in cerebrospinal fluid has been performed in 37 patients with chronic myeloid leukemia at different clinicohematological stages. The age of the patients ranged from 16 to 67 years. CNS involvement has been diagnosed in 8 (21.6%) patients by clinical and cytological criteria and in 5 (13.5%) patients on the basis of changes in liquor cytograms and in biochemistry. Morphological substrate of leukemic infiltration may be represented by blast cells and cells of granulocytic line of all stages of differentiation. Direct correlation has been established between ferritin and beta-2-microglobulin levels in liquor and its cytological patterns. This permits a conclusion on possible usage of liquor concentration of beta-2-microglobulin and ferritin measurements as additional tests in the diagnosis of neuroleukemia in chronic myeloid leukemia.
