Evaluation of the histologic changes of the bone marrow and clinical data of twelve male and two female patients with hairy cell leukamia before treatment. Mean age of the patients was 46 years, time from the onset of symptoms 5.5 months. 13 of the patients were anaemic, showing splenomegaly, 12 suffered from thrombopenia, 9 from granulocytopenia, and 8 from hepatomegaly. In all of the cases, the relative numbers of lymphocytes in the blood had been increased together with various amounts of characteristic hairy cells. All of the cases had a typical histologic picture of lymphocytic bone marrow infiltration, mostly of the diffuse type. In 50% of the cases not only the well known rod-like intracellular inclusions could be seen, but also ring-shaped figures whose significance is discussed. Decrease of the granulopoiesis, disintergration of the marrow sinusoids, and osteoporosis are the most important additional signs. The progression of the disease is marked by increasing bone marrow infiltration, by splenohepatomegaly, anaemia, thrombopenia, and increasing numbers of typical lymphocytes in the blood. The bone marrow being considered to be the origin of the disease for good reasons, the histobiopsy of this organ ranks among the diagnostic and prognostic measures to be taken at first sight.

We describe 3 cases of acute graft-versus-host (GVH) disease in patients with acute myeloid leukaemia following transfusions taken from non-HLA-identical healthy donors. The leucocyte transfusions were given because of severe bone marrow aplasia and granulocytopenia following leukaemia induction treatment. The first patient had an acute GVH reaction with an erythrodermia-like skin reaction all over and associated with severe abdominal cramping, enlarged liver and pathological liver function tests. The second patient had a relatively mild skin reaction and enlarged liver. Both died of severe pulmonary infection. The third patient also had a mild skin reaction and enlarged liver. He died of pulmonary embolism. The diagnosis of GVH of the latter 2 cases was made on skin biopsy. The autopsy samples revealed in all cases a heavy lymphocytic infiltration of the kidneys and liver portal area. Until more precise guidelines can be established, irradiation of blood cell products given to patients with neutropenia due to leukaemia induction treatment should be considered.

A population of patients with agranulocytosis admitted to a general hospital over a period of 12 yr was studied retrospectively in order to determine the causes of the disease. Of the 48 cases identified, 31 (65%) had drug-induced neutropenia, whereas 17 (35%) had chronic neutropenia unrelated to the use of drugs. Eight patients had an underlying hematological malignancy. Patients with agranulocytosis not induced by drugs more frequently had hepatomegaly, splenomegaly, enlarged lymph glands, or thrombocytopenia together with severe anemia. In contrast, drug-induced agranulocytosis was more severe, with a higher incidence of positive blood cultures, low cellularity of initial bone marrow aspirates, and a shorter duration of neutropenia. Dipyrone and methimazole were the drugs most commonly associated with agranulocytosis. Dipyrone was probably the causative agent in two of the seven drug-induced fatalities. In view of these findings, and those of several previous reports, it is proposed that the use of dipyrone in Israel be severely restricted or discontinued altogether.

Thirty-six patients with hairy-cell leukemia (HCL) were evaluated, and were divided in two major subtypes: leukopenic (WBC less than 3000/microliters) and non-leukopenic (WBC greater than or equal to 3000/microliters). There were 22 leukopenic and 14 non-leukopenic patients. The leukopenic group were older than the non-leukopenic group, with an average age of 58.4 years compared with 47.6 years. The male/female ratio was higher in the leukopenic (6.3) than the non-leukopenic (2.0) patients. Splenomegaly, hepatomegaly and lymphadenopathy were found in 66%, 32%, and 18% of the leukopenic patients, compared with 92%, 57%, and 35% in the non-leukopenic patients. The leukopenic HCL was associated with more severe anemia, granulocytopenia, monocytopenia, and thrombocytopenia, and higher incidence of serious infections than the non-leukopenic HCL. Increased bone marrow reticulin fibers and unsuccessful marrow aspirations (dry taps) were more frequently associated with the leukopenic than the non-leukopenic HCL.
