Twelve patients with acute, untreated inflammatory bowel disease (IBD) were followed prospectively for coagulation and platelet function. With no symptomatic coagulopathy, abnormalities were found in all patients. With acute diseases, elevations of fibrinogen (9/12), factor V (8/12), and factor VIII (6/12) were common. Depressions of antithrombin III levels were also observed acutely (8/12). Abnormalities of platelets were both quantitative and qualitative. Thrombocytosis was present (11/12), and abnormalities in the rate and percent platelet aggregation were seen (9/10). During therapy, factors V and VIII, antithrombin III levels, and the quantitative and qualitative platelet abnormalities returned towards normal in direct correlation with sedimentation rate and clinical disease activity.

Platelets contain heparin neutralizing activity, which is released into plasma following aggregation. This material is probably identical to platelet factor 4. We describe a technic to measure heparin neutralizing activity in platelet-poor plasma based on the serial heparin dilution technic of Harada and Zucker. Heparin neutralizing activity was depressed in thrombocytopenia due to immune thrombocytopenia and bone marrow depression, and elevated in thrombocytopenia due to disseminated intravascular coagulation. Secondary thrombocytosis is characterized by markedly elevated heparin neutralizing activity, while thrombocytosis associated with myeloproliferative disorders has normal heparin neutralizing activity.

Hematological investigations were carried out regularly during the course of an experimental M. arthritidis-infection in rats. The alterations observed in the peripheral blood were essentially those usually found in infections. In addition, a moderate thrombocytosis and a depression of the parameters of the red blood count could be seen. In lymphnodes and spleen phagocyting RES-cells were increased 4 days post inoculationem (p.i.) and vacuolized makrophages could be observed 7 days p.i. On the 10. day p.i. very immature cells could be seen in these organs, morphologically resembling hemohistioblasts. Mature cells as well as precursors of this type of cell were found to be increased 2-3 weeks p.i. Bone marrow and thymus have been found normal during the whole period of investigation.

Clinical and haematological features of 61 patients with drug-induced agranulocytosis (63 episodes) are presented. Multiple drug consumption was a common observation and complicated the attempt to incriminate a particular drug as being aetiologically involved. Bone marrow analysis shortly after the diagnosis revealed evidence for an impairment of proliferative granulopoiesis in the majority of cases. This observation was confirmed by in vitro culturing of granuloid precursor cells (CFU-c). Moreover, the data clearly demonstrated that drug-induced agranulocytosis may not be restricted to the granulocytic series. Thrombocytosis and reticulocytosis during the recovery phase are taken as an indication for the commitment of all haemopoietic cell lineages in agranulocytosis. These observations were in accordance with cytomorphological studies and in vitro culture data of erythroid precursor cells (CFU-e, BFU-e) of bone marrow aspirates taken in the initial phase of agranulocytosis. More than 25% of the patients showed a marked erythroid depression in the marrow.

Changes in all three blood cell systems could be covered in 50 patients treated in hospital for a high consumption of alcohol for years and even decades. There is no symptom which would be pathognomonic for alcoholism in itself. Macrocytosis and macrovoluminity of erythrocytes, hyper-sideraemia and thrombocytopenia were findings frequently encountered and easily to be identified. Megaloblasts, vacuolization, and an increase of sideroblasts could be observed in the bone-marrow. The prompt reversibility of these changes mentioned by simply abstaining from alcohol has a considerable diagnostic utility. The impact of liver damage partly produced by an accompanying spleen enlargement could only be ensured for thrombocyte depression. The increase of methaemoglobin which is unequivocal but without any clinical importance can also be reversed by alcohol deprivation. From a haematological point of view an alcoholic is endangered by a deficient immunological system. Haemorrhagic diatheses due to thrombocytopenia, thromboembolic complications during rebound-thrombocytosis and severe haemolyses can rarely be found.

A total of 117 cases with hematological malignancies were treated with MCNU at doses of 70-100 mg/m2. Following are the results obtained. 1. MCNU showed a marked depression of cells in the cases with CML, polycythemia vera and thrombocythemia. The low level of cells was maintained for 2 to 7 months. 2. A good response was observed in several cases with blastic crises of CML. 3. No response was observed in two cases with acute leukemia. 4. Although a fair response was observed in several cases with malignant lymphoma or multiple myeloma, moderate bone marrow suppression was observed in a majority of the cases.

A role for interleukin-6 (IL-6) in malignant mesothelioma has been suggested by the clinically presenting symptoms of mesothelioma patients, which include fever, weight loss and thrombocytosis. A murine model of malignant mesothelioma was therefore used to examine the potential role of IL-6 in this cancer type and whether the effect of interferon alpha (IFN alpha) therapy on mesothelioma might be mediated, in part, by regulating IL-6 levels and/or IL-6-induced pathobiology. A panel of human and murine mesothelioma cell lines was assayed for endogenous IL-6 production in a bioassay, and for IL-6-mRNA expression. Four out of 5 human and 5 out of 15 murine mesothelioma cell lines produced moderate to high levels of bioactive IL-6 in vitro. This result was corroborated by mRNA detection. One of the representative murine cell lines, AB22, was chosen for further in vivo studies in the murine mesothelioma model. In AB22-inoculated mice detectable serum IL-6 levels were found to precede macroscopically detectable tumour growth, clinical signs (cachexia, abdominal distension, diarrhoea) and changes in the peripheral lymphoid organs (cell depletion and functional depression). Treatment with anti-IL-6 antibody curtailed the clinical symptoms (P < 0.001), as did treatment with recombinant human (rhu) IFN alpha (P < 0.001). Neither anti-IL-6 antibody nor rhuIFN alpha had a direct growth-inhibitory effect on the AB22 mesothelioma cell line in vitro, however, in vivo rhuIFN alpha treatment of mice inoculated with AB22 cells attenuated both IL-6 mRNA expression in the tumours and serum IL-6 levels, ameliorated the depression of lymphocyte activities, and enhanced the number of tumour-infiltrating lymphocytes and macrophages. On the basis of these results it is suggested that IL-6 mediates some of these effects, directly or indirectly, and that a combination therapy of rhuIFN alpha and anti-IL-6 antibody may be an improved palliative treatment for patients with malignant mesothelioma.

In ten patients with essential thrombocythemia and polycythemia vera with thrombocytosis we have investigated the therapeutic effect of recombinant alpha-2a interferon (Roceron-A) given subcutaneously in a maintenance dosage of 3 million units three times weekly. The aim was to normalize the platelet count (< or = 400 x 10(9)/L). One of the secondary aims was to study platelet activity measured as beta-thromboglobulin (beta-TG) in urine. All but one patient could administer the injections and in all patients a significant reduction in platelet values was seen. The treatment was discontinued in three patients due to side effects of interferon, two because of hair loss (one with irreversible alopecia), and one because of depression. Three patients developed antibodies to alpha-2a interferon and a concomitant rise in the platelet level; in one patient therapy was switched to leukocyte alpha-interferon with an excellent response. The initial levels of beta-TG were elevated in 9/10 patients and were significantly reduced at 6 months in 4/5 patients not developing antibodies. Six patients are still on alpha-interferon therapy with a long-term follow-up of 3-3.5 years. We conclude that alpha-interferon therapy may be an alternative in patients with thrombocytosis and/or complications necessitating treatment.

Sixteen patients with polycythaemia vera or essential thrombocythaemia were treated with interferon-alpha in order to normalize elevated platelets. Patients were followed for 6 months and the frequency and intensity of symptoms and side effects were recorded before and during the study period by the patients and by the doctor. Health-related quality of life was also assessed. The most frequently reported pretreatment symptoms were fatigue, headache and muscle pain. The intensity of fatigue initially increased during treatment and there was no relief of any of the three most frequent symptoms during the treatment period. Common interferon-related symptoms such as fever and chills were most frequently reported after one week. After one month of treatment, symptoms related to the gastrointestinal tract reached a peak. Two patients discontinued treatment during the study period. Another patient suffered severe depression after the study period when still on interferon. There was no difference between the frequency of symptoms recorded by the doctor and that reported by the patients.

Anemia is common in congestive heart failure (CHF) and is associated with an increased mortality and morbidity. The most likely causes of anemia are chronic kidney disease (CKD) and excessive cytokine production, both of which can cause depression of erythropoietin (EPO) production and bone marrow activity. The cytokines also induce iron deficiency by both reducing gastrointestinal iron absorption and iron release from iron stores located in the macrophages and hepatocytes. Iron deficiency can cause thrombocytosis which might also contribute to cardiovascular complications in both CHF and CKD and is partially reversible with iron treatment. Thus attempts to control this anemia will have to consider both the use of erythropoiesis-stimulating agents (ESA), such as EPO, as well as oral and, probably more importantly, intravenous (IV) iron. The many studies on anemia in CHF patients treated with ESA and oral or IV iron, and even with IV iron without ESA have up to now shown a quite consistent positive effect on hospitalization, fatigue, shortness of breath, quality of life, exercise capacity, and beta-natriuretic peptide reduction, in the absence of increased cardiovascular damage related to the therapy. Adequately powered long-term placebo-controlled studies of ESA and/or IV iron are currently being carried out and their results are eagerly awaited.
