Hairy cell leukemia and other "hairy-cell" lymphoproliferative disorders (LPD-HC): the significance of morphologic, histologic and immunologic studies.

In this report the clinical, morphologic, histologic and immunologic findings of 41 patients with hairy lymphoid cells in peripheral blood and/or bone marrow are analyzed. In 27 patients the diagnosis of hairy cell leukemia was established. 14 patients had other variants of lymphoproliferative disorders: malignant lymphoma with hairy cells--7, chronic lymphocytic leukemia with hairy cells--5, and T cell lymphoproliferative disorder with hairy cells--2 patients, respectively.

Temporary organ substitution by hemoperfusion through suspension of active donor hepatocytes in a total complex of intensive therapy in patients with acute hepatic insufficiency.

The results of intensive therapy and temporary organ substitution by hemoperfusion through a suspension of active hepatocytes in 126 patients suffering from acute hepatic insufficiency (AHI) induced by virus B hepatitis, virus non-A, non-B hepatitis, acute toxic hepatitis, active liver cirrhosis, sepsis leptospirosis long-term subhepatic jaundice are presented in this paper. Hepatic encephalopathia confirmed both clinically and electroencephalographically was registered in all the patients. The patients were subdivided into two groups: a complex of commonly used curative measures according to the intensive therapy for AHI was applied in Group A (67 patients); in Group B (59 patients), alongside with the above measures, temporary organ substitution by hemoperfusion through a suspension of active porky hepatocytes was also performed.

Phenotypic heterogeneity of B cell chronic lymphocytic leukaemia.

FAB classification of chronic myelomonocytic leukemia: heterogeneity revealed on the basis of bone marrow findings.

We report on 12 patients who fulfilled the FAB diagnosis criteria of chronic myelomonocytic leukemia (CMML). Some clinical findings (splenomegaly) as well as biological parameters (WBC count, cellularity of bone marrow sections, presence of dyserythropoiesis in bone marrow smears) were subjected to particular analysis. This allowed the assignment of each patient onto one of three separate hematological syndromes: (1) RA or RAEB with monocytosis, (2) myelomonocytic dysplasia (a novel syndrome) and (3) true CMML.

Subpopulations of T lymphocytes in psoriasis patients and their changes during immunotherapy.

The content of T-lymphocytes and their basic subpopulations T-helpers and T-suppressors have been studied by means of monoclonal antibodies in the peripheral blood of 104 patients with different forms of psoriasis (56 patients with psoriasis vulgaris, 25 with exudative psoriasis, 10 with psoriasis arthropathica, and 13 with erythrodermic psoriasis). In all forms of psoriasis with a slight alteration in T-lymphocyte content a significant dysbalance of T-helpers and T-suppressors was found that brought about a decrease in the correlation ratio T-helpers/T-suppressors (T-helpers/T-suppressors in patients suffering from psoriasis vulgaris, 1.55 +/- 0.
