Sixty cats with hematologic abnormalities indicative of non-lymphoid hematopoietic neoplasia were classified into two groups, myelodysplastic syndromes (MDS) and acute myelogenous leukemias (AML), using criteria developed for human patients with similar diseases. Cats with myeloblast counts in bone marrow of less than 30% were classed as MDS and cats with myeloblast counts of 30% or greater were classed as AML. The clinical, laboratory, and postmortem findings in each group were described and compared. Clinical signs of disease were similar in both groups, the most common being inappetance, lethargy, and weakness. Non-regenerative anemia, macrocytosis, neutropenia, and thrombocytopenia were frequent hemogram abnormalities in both groups. Diagnostically useful differences in physical and peripheral blood findings were a higher prevalence of splenomegaly and/or hepatomegaly, thrombocytopenia, and severe anemia in the AML group. Circulating myeloblasts were found only in cats in the AML group. Outcome of disease was similar in both groups; 85% of the cats in each group died or were euthanatized within one week of diagnosis. In cats that were necropsied, extramedullary leukemic infiltrates were found in all cats in the AML group and in none of the cats in the MDS group.

A four-month-old boy affected by glycogen storage disease type I is presented. The child suffered from hepatomegaly, lactic acidosis, fasting hypoglycemia and failure to thrive. He had repeated infectious and cyclic neutropenia. Immunoglobulin and chemotactic neutrophil motility was impaired. Liver biopsy showed increased amounts of glycogen in hepatic cells as assessed by morphological and biochemical grounds. The activity of glucose-6-phosphatase as well as other glycogenolytic enzymes was normal in the frozen liver. The aforementioned characteristics suggested the diagnosis of glycogen storage disease type Ib. The child was first treated by enteral continuous feeding and later on by frequent meals during the daytime and enteral continuous feeding during the night time, improving the hypoglycemia as well as the other biochemical and metabolic abnormalities.

A clinical and hematopathologic review of 66 patients with systemic mast cell disease (SMCD) was undertaken to investigate the frequency and the clinical significance of associated hematologic disorders. Twenty-two patients were found to have a second hematologic disorder, 19 of which involved the myeloid cells (ten dysmyelopoietic syndromes, five myeloproliferative disorders, three acute nonlymphocytic leukemias, and one chronic neutropenia), and three of which involved the lymphoid cells (three malignant lymphomas). A chromosome analysis of the bone marrow revealed abnormalities characteristic of neoplastic myeloid disorders in four patients. Five-year survival for patients with hematologic disorders was 28% compared with 61% for other SMCD patients (P = 0.004). Patients with hematologic disorders differed significantly from other SMCD patients in that they were about 7 years older (P = 0.039), and they presented more commonly with anemia (P less than 0.001) and constitutional symptoms (P = 0.007). These patients also had less frequent skin symptoms (P = 0.003) and urticaria pigmentosa (P = 0.018). By definition, patients with hematologic disorders had a greater percent of hematopoiesis (P less than 0.001) and decreased fat cells (P = 0.011) on bone marrow biopsies. A multivariate model demonstrated that the following independent variables were associated with the presence of hematologic disorders: low hemoglobin (P = 0.001), the absence of hepatomegaly (P = 0.016), high leukocyte count (P = 0.021), and the presence of pathologic fractures (P = 0.051). The frequent coexistence of SMCD with dysplastic and neoplastic disorders of myeloid cells is consistent with the concept that SMCD itself is a disorder of myeloid cells and that the mast cell may be myeloid in origin.

The authors have studied the case of a female patient with rheumatoid polyarthritis, who developed a lymphocytic proliferation in the blood, the marrow, and the liver, associated with a neutropenia. Several similar cases have been recently reported in the literature. The cellular proliferation is made of large granulous lymphocytes and the study of membrane markers enables to find the following homogeneous phenotype: E rosette+, CD8+, HNK-1+, FcR+, CD4-luminal diameter "divided by degrees - -, IgS-, HLA class II-. This lymphocytic sub-population produces little interleukin-2, responds weakly to mitogens (PHA, CON A, PWM), and inhibits the response of normal lymphocytes to the same mitogens. These lymphocytes have a weak natural killer activity but, on the contrary, develop a very strong cytotoxic activity which is antibody-dependent. Clinically, splenomegaly, anemia and infections are frequent and hepatomegaly or thrombopenia more rare. Adenopathies are never present. The evolution is chronic in nature and not very aggressive, although the lymphocytic proliferation is monoclonal in origin, as demonstrated in molecular biology studies. The neutropenia might be secondary to an inhibiting effect of lymphocytes on the granular precursors of the bone marrow. There is a definite association between this lympho-proliferative syndrome and rheumatoid polyarthritis, and this association appears to be different from the Felty's syndrome.

Visceral leishmaniasis (kala-azar) is an important cause of morbidity and mortality in widely scattered areas of the world. To better characterize the South American form of the disease, the clinical and laboratory manifestations of 29 patients admitted to hospital (18 male and 11 female patients, mean age 4.9 years), were assessed in an endemic area in northeastern Brazil. Fever, weight loss, pronounced splenomegaly, hepatomegaly, anemia, thrombocytopenia, relative neutropenia, hypoalbuminemia and hypergammaglobulinemia were found in the majority of patients. Symptoms were often present for two or more months before diagnosis. Secondary infections complicated many cases; there were ten cases of pneumonia and half of the patients had one or more intestinal parasites. The average length of hospital stay was 27 days; all patients were treated with meglumine antimoniate (Glucantime). The mortality rate was 3%. American visceral leishmaniasis remains an important disease among children living in endemic areas.

Glycogen storage disease type Ib has all the clinical manifestations of glycogen storage disease type Ia such as hepatomegaly, growth retardation, bleeding tendency, hypoglycemia, hyperlactacidemia, hyperuricemia, hyperlipidemia, impaired platelet function plus neutropenia. The overall glucose-6-phosphatase activity in disrupted microsomes from liver is normal whereas glucose-6-phosphate translocase, the first enzyme in the glucose-6-phosphate transport system is absent. There is no glucose-6-phosphatase activity in vivo. Recent results show that in granulocytes the glucose-6-phosphate-dependent hexosemonophosphate-shunt is impaired.

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.

Type IB Glycogen storage disease (GSD) is a new variant of type I Glycogen storage disease. It is characterized by same clinical findings: hepatomegaly, fasting hypoglycemia, hyperlipidemia, hyperuricemia, lactic acidosis, renal enlargement, short stature; but it distinguish for normal glucose-6-phosphatase hepatic activity in vitro. The involvement is in G-6-P transport system. Recently has been described in some patients with GSD IB, neutropenia and defective neutrophil mobility. In this report the authors described two family cases of GDS IB that one characterized by severe neutropenia.

From 1972 to 1981 10 patients with hairy cell leukaemia were observed in the Medical University Clinic Cologne, this represents 1.8% of all leukaemias. Typical clinical signs are splenomegaly, no or only slightly enlarged lymph nodes and a moderate hepatomegaly. Almost in all cases an anaemia, thrombocytopenia and neutropenia with lymphocytosis was found, mostly combined as pancytopenia. The pathognomonic tartrate resistant acid phosphatase was found in the hairy cells to a differing amount besides a fibrosis and a lymphatic infiltration of the bone marrow. A normalization of the anaemia, the thrombocytopenia and the neutropenia was reached by splenectomy, but the increased susceptibility to infections could not be affected significantly.

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.
