Blood platelets were assayed in 56 cirrhosis patients divided into two groups: alcoholic cirrhosis (20 cases) and non-alcoholic cirrhosis (36 cases). Each group was also divided into two sub-groups: with and without clinical signs of portal hypertension. Low platelet counts were found in both groups (greater than 70%), the incidence being high in the sub-group with clinical signs of portal hypertension. Alcohol appeared to have no influence on the development of platelet insufficiency which was rather correlated with the severity of the hepatopathy, the presence of splenomegaly (splenic sequestration), immunological factors, (presence of circulating antiplatelet antibodies) and "consumption" phenomena (significant incidence of circulating FDP, and indicator of chronic Disseminated Intravascular Coagulation).

The recently described monocytoid B-cell lymphoma is a low-grade lymphoma presenting most frequently in elderly women and commonly associated with autoimmune diseases. Leukaemic expression of this disease has been reported in advanced stages. A case of monocytoid lymphocytosis without lymph node enlargement is presented herein. A 60-year old woman complaining of easy bruises was found to have a 2-cm splenomegaly. Her laboratory data included the following: haemoglobin, 125 g/L; haematocrit, 0.35 L/L; white cell count, 29 x 10(9)/L with 32% PMN, 3% stabs, 2% myelocytes, 1% metamyelocytes, 30% lymphocytes and 32% atypical mononucleated cells showing wide, pale cytoplasm neatly contoured and oval nucleus with monocytoid features. The basal coagulation study showed prothrombin 50%, APTT 40 seconds, fibrinogen 68 mg/dL and FDP between 80 and 160 ng/dL. Splenomegaly without lymph-node enlargement was found on CT scan. The bone-marrow biopsy showed a 68% monocytoid lymphocytic infiltration, acid-phosphatase positive and tartrate-sensitive, without fibrosis. Bone-marrow and peripheral immunophenotype showed those cells to be CD22, CD 19 and CD11 positive, while T and CD25 markers were absent. The patient was treated with alpha-2b interferon at a dose of 3MU three times a week for 6 months, with general improvement and regression of the leukaemic expression. Eleven months after diagnosis she died of a central nervous system haemorrhage. The morphological, immunological and cytochemical features of the monocytoid lymphocytes in this case are commented, along with their variable behaviour. A review of the literature is also carried out, attention being laid on the onset and the response to therapy of B-cell monocytoid lymphomas as the singularity of this case lies on its exclusively leukaemic onset. It is concluded that an interrelationship between monocytoid B-lymphocytic leukaemia and B-cell monocytoid lymphoma might possibly exist, such as that between chronic lymphocytic leukaemia and diffuse lymphocytic lymphoma.

A 61-year-old woman experienced a high fever with anemia and APTT prolongation after suffering a herpes zoster virus infection. Physical examination revealed a large splenomegaly without lymphadenopathy. Laboratory evaluations were positive for lupus anticoagulant (LA) and monoclonal IgM-kappa protein. LA was associated with the presence of anti-beta2GPI antibody, anti-cardiolipin antibody, and anti-prothrombin antibody. Moreover, the results of factors IX, XI, and XII assays and CRP and FDP-E were disturbed. A splenectomy was performed, and a splenic marginal zone lymphoma (SMZL) was diagnosed. All hematological findings rapidly recovered after the splenectomy. No thrombotic events occurred after the splenectomy even though thrombosis prophylaxis was not performed. The clinical course suggested that the SMZL-producing antibody induced immunological abnormalities in the labolatory tests. Since the patient suffered disease progression soon after the splenectomy, an autologous peripheral stem cell transplantation with rituximab administration was performed.

Thrombocytopenia is frequently observed in vivax malaria but the exact mechanism has not been elucidated. We studied 27 cases of acute vivax malaria out of which 24 cases had thrombocytopenia. This was the most common hematological finding. None had bleeding from any site. Anaemia and splenomegaly were not present in any of the cases. Platelet counts reverted to normal on treatment. Other causes of thrombocytopenia were ruled out by complete history and physical examination, dengue serology and blood culture. DIC was ruled out by peripheral smear examination and measurement of FDP levels. Our study stresses the importance of thrombocytopenia as an early indicator for acute malaria; a finding that is frequent and present even before anemia and splenomegaly set in. The possible mechanisms leading to thrombocytopenia in malaria have been discussed which include immune mechanisms, oxidative stress, alterations in splenic functions and a direct interaction between plasmodium and platelets.
