Diagnosis and prognosis of overt disseminated intravascular coagulation in a general hospital -- meaning of the ISTH score system, fibrin monomers, and lipoprotein-C-reactive protein complex formation.

The meaning, the utility, and the prognostic significance of the International Society of Thrombosis and Hemostasis overt disseminated intravascular coagulation (DIC) score and other parameters of coagulation activation including soluble fibrin monomer complexes (SFMC), antithrombin and protein C consumption, and formation of lipoprotein-C-reactive protein (LP-CRP) complexes (MDA slope 1 and flag A2) were evaluated in 165 inpatients from a general hospital for whom DIC testing was required by the attending physicians. Of these 165 patients, 148 had an underlying disease that clearly justified the laboratory request from our systematic post hoc review of the clinical charts. Of these 148 patients, 28 had a positive overt DIC score, 19 had an A2 flag, and 4 had both.

On the value of intensive remission-induction chemotherapy in elderly patients of 65+ years with acute myeloid leukemia: a randomized phase III study of the European Organization for Research and Treatment of Cancer Leukemia Group.

We report the results of a prospective study in patients more than 65 years of age in whom two different therapeutic strategies were compared: immediate intensive-induction chemotherapy (arm A) versus "wait and see" and supportive care and mild cytoreductive chemotherapy only for relief of progressive acute myeloid leukemia (AML)-related symptoms (arm B). The major objective of the study was to compare survival outcome of both regimens. Thirty-one patients on arm A received one or two courses of daunorubicin, vincristine, and cytarabine for remission induction followed by one additional cycle for consolidation in case of complete remission (CR).

A phase II study of alternating combination chemotherapy in 55 myeloma patients. A comparison with non-alternating combination chemotherapy and treatment with a single cytostatic.

Fifty-five consecutive patients with stage II and III myeloma were treated at 7 centers with alternating combinations of 7 cytostatics and prednisolone. 30/48 evaluable patients responded to the combination chemotherapy, 10/55 patients died within 15 months, and the median survival was 40 months. No advantage could be shown over a previous non-alternating combination of two cytostatics.

Enzymes of purine metabolism in B-chronic lymphocytic leukemia.

In order to study if enzymes of purine metabolism could be used as cell markers in B-chronic lymphocytic leukemia (B-CLL), the activities of adenosine deaminase (ADA), purine nucleoside phosphorylase (PNP), and 5'-nucleotidase (5'N) were repeatedly measured in blood mononuclear cells from B-CLL patients and were compared to those obtained in normal controls. Enzyme activities in patients were also compared to other biological parameters indicative of B-CLL to activities of ADA and PNP in erythrocytes. Results show that B-leukemic cells display abnormal enzyme patterns: subnormal ADA activity is characteristic; 5'N activity is depressed in 60% of the cases but increased in 15%.

Thymidine kinase and thymidine phosphorylase activities in various types of leukaemia and lymphoma.

Thymidine kinase (TK) isoenzymes and thymidine phosphorylase (TP) activities have been measured in peripheral mononuclear cells of patients with acute lymphoblastic and monoblastic leukaemia or B-chronic lymphocytic leukaemia, as well as in normal subjects, and also in lymph node cells from patients with non-Hodgkin's lymphoma, with Hodgkin's disease and with benign adenopathies. TK1 isoenzyme activity was highest in acute lymphoblastic leukaemia and in centroblastic lymphoma. Then in progressively decreasing order appeared the Hodgkin's disease values, the centroblastic centrocytic lymphoma values and the benign reactive lymph node cell values.

[Myeloma and hypereosinophilic leukemoid reaction (author's transl)].

In a 56-year-old man with a myeloma marked eosinophilia was discovered. The diagnosis of myeloma was made on the discovery of plasmocyte infiltration in the mandible. Despite surgery and chemotherapy, general bone infiltration by plasma cells occurred over 15 months.

Cellular aspects of selective IgA deficiency.

Five patients with no detectable serum IgA (less than 20 mug/ml) and one patient with low serum IgA were compared to normal subjects. The number of circulating E-RFC was normal as was the lymphocyte DNA synthesis induced by PHA, Con A, and streptokinase-streptodornase. The patients had normal numbers of IgA-bearing lymphocytes and normal or increased numbers of B cells.

A rare and complex case of multifocal mucocutaneous lupus tuberculosis with isolated lesion of the tongue.

We have described a case of plurifocal tuberculous lupus with a localization limited to the tongue. This finding is remarkable because of its rarity. The weakly positive tuberculin reaction and the discovery of a concomitant myeloproliferative syndrome add interest and complexity to the case.
