Heart disease characterized by endomyocardial fibrosis is one of the major causes of morbidity and mortality in the idiopathic hypereosinophilic syndrome. From our series of 50 patients with idiopathic hypereosinophilia, we defined the noncardiovascular characteristics that distinguish patients at risk of developing endomyocardial fibrosis from those who remain free of heart disease. These groups did not differ with respect to the extent of eosinophilia or the duration of disease. Patients with clinically overt heart disease were more likely (p less than 0.05) to be male and HLA-Bw44 positive and have splenomegaly, thrombocytopenia, elevated serum levels of vitamin B12, and hypogranular or vacuolated eosinophils and abnormal early myeloid precursors in the peripheral blood. These idiopathic hypereosinophilic patients with heart disease were also more likely to have fibrosis and decreased megakaryocytes in the bone marrow. In contrast, those who remained free of heart disease tended to be female and have angioedema, hypergammaglobulinemia, elevated serum levels of immunoglobulin E (IgE), and circulating immune complexes. Therefore, in the idiopathic hypereosinophilic syndrome, male patients with a myeloproliferative type disorder and the HLA-Bw44 haplotype were at a much increased risk for the development of endomyocardial fibrosis. However, those patients with a hypersensitivity-like illness and angioedema who were female did not develop heart disease. Appreciation of this relative degree of risk for the major complication of the idiopathic hypereosinophilic syndrome should prove useful in the early identification and appropriate treatment of patients in whom endomyocardial fibrosis might develop.

Clinical and laboratory findings at the time of diagnosis were correlated with the survival of 242 patients with chronic myelocytic leukemia. Twelve patients with the blastic stage of the disease (blasts greater than or equal to 29%) had a median survival of eight months. Of the nonblastic patients, 28 without the Philadelphia chromosome had a relatively constant mortality averaging 43% per year and a median survival of 13 months, markedly worse than the Ph1-positive group (mortality, 6% in the first year, 17% in the second year, and the 25% per year, with a median survival of 43 months; P less than 0.001). In the latter group of 202 patients, features reflecting the "quantity" of leukemia (leukocyte count, marrow cellularity, and M:E serum B12, different degrees of splenomegaly, presence or absence of symptoms) had weaker or short-term correlations with mortality, while "qualitative" abnormalities (e.g., increased percentage of circulating blast, extramedullary leukemic tumors, major abnormalities of erythropoiesis or platelet production, marked basophilia or eosinophilia) had strong and persistent correlations with mortality. Chromosome abnormalities in addition to the Ph appeared to have a delayed though significant effect on survival. Serum alkaline phosphatase and SGOT levels did not correlate significantly with survival, but major elevations of serum LDH were associated with increased mortality throughout the course of the disease.

Full blood counts and some serum biochemistry were carried out on 349 male and 22 female apparently healthy Papua New Guinea subjects, most of whom were highlanders. In males, RBC, Hb, PCV, MCH, MCHC, serum albumin, ferritin, iron, per cent transferrin saturation and folate means were significantly lower than the Australian normal means; WBC and MCV means were similar to Australian values; and eosinophil and reticulocyte counts and serum transferrin and vitamin B12 means were higher than Australian means. In females, WBC, RBC, Hb, PCV, MCV, MHC, MCHC and serum ferritin means were lower than Australian means; eosinophil counts, serum iron, per cent transferrin saturation, and folate means were similar to Australian means; and serum transferrin and B12 means were higher than the Australian means. Hepatomegaly and mild splenomegaly were common. beta-Thalassemia was present in three subjects two of whom were from Simbu Province.

We describe a 77-year-old patient with chronic neutrophilic leukemia (CNL). Diagnosis of CNL was made by marked increase of mature neutrophils without increased immature granulocytes, splenomegaly and elevated serum vitamin B12 level and by ruling out any infection or occult malignancy. The chromosome analysis showed one abnormal karyotype out of 14 metaphases. The neutrophilic function with nitroblue tetrazolium test revealed impaired phagocytic function in this patient. The neutrophil count became normal gradually after hydroxyurea treatment. However, it still maintained a high percentage of mature neutrophils. Background literature and the prognosis of CNL are discussed.

Imerslund-Najman-Grasbeck disease is a rare inherited megaloblastic anaemia secondary to a selective malabsorption of vitamin B12 by ileal enterocytes. The authors report on a 4 year-old tunisian girl who presented as visceral infantile leishmaniasis because of huge splenomegaly and major anaemia. The diagnosis of Imerslund disease was performed on the basis of the association of typical megaloblastic cells in the marrow, permanent proteinuria and favourable outcome under parenteral B12 administration. In addition, ther were no folate deficiency, no anti-intrinsic factor antibodies and no intrinsic factor deficiency. The outcome of the disease is always favourable if parenteral administration of vitamin B12 maintained.

Treatment of a 74 year old patient with chronic myelogenous leukemia (CML) with busulphan resulted in an abrupt and pronounced decrease of the white blood cell (WBC) count with restoration of normal peripheral blood cell morphology and regression of splenomegaly. The Philadelphia positive (Ph+) clone was however still detectable. The alterations in the WBC count and morphology were not preceded by marrow hypoplasia but correlated closely with a marked decrease in the serum levels of Transcobalamin I (TC I), a vitamin B12-binding protein derived from immature myeloid precursors and a reciprocal rise in serum TC III, a vitamin B12-binding protein originating from terminally differentiated mature granulocytes. Studies on the HL-60 cell line showed that busulphan is capable of inducing leukemic cells to differentiate into granulocyte-like cells. These observations, taken together, suggest that in addition to its potent myelosuppressive effects, busulphan may induce apparent clinical remissions in some CML patients by promoting terminal cell differentiation.

A 74-year-old man was admitted because of swelling, pain and ecchymosis in the night lower extremity. A blood analysis revealed that Hb was 11.8g/dl, WBC 37,600/microliters, and platelet count 137.1 x 10(4)/microliters. The NAP value was high. Bone marrow examination disclosed marked megakaryocytic hyperplasia. Chromosomal analysis revealed 47, XY, +9. Hemostatic data were within normal ranges, but the 2nd aggregation of platelet by ADP was diminished. The serum beta-TG was 159, PF-4 56ng/ml, B12 1,100, UB12 BC 1,800pg/ml. Gastric fiberoscopy revealed gastric cancer and CT scan disclosed marked splenomegaly. Essential thrombocythemia (ET) coexisting with gastric cancer was diagnosed based on these examinations. He was treated with anti-platelet agents, busulfan and tegafur uracil, however thromboembolic symptoms suggesting central nervous system and peripheral vascular ischemia and gastrointestinal bleeding occurred. Among diagnostic criteria for ET established by the polycythemia vera study group, there is a category "No known cause for reactive thrombocytosis." The case reported here had gastric cancer which may have contributed to the elevated platelet count, however this case could be diagnosed as ET coexisting with gastric cancer because of the above various clinical signs and laboratory results. Although then are few reports of the coexistence of other malignancies in ET, there may be many more similar cases because of the age preponderance in ET. In order to diagnose ET more precisely, more strict diagnostic criteria are needed.

A 54-year-old woman with leukocytosis, was referred to our clinic in February 1982. Based on findings of pancytosis, high NAP score, high serum vitamin B12, increase in total red cell volume and splenomegaly, she was diagnosed as having polycythemia vera (PV). Since then, she has been treated with pipobroman, hydroxycarbamide and phlebotomy. Leukocytosis with increase in blastic cells and thrombocytopenia was noted in August 1995, and she was admitted to our hospital. Since the blastic cells were CD10(+)19(+)20(+), she was diagnosed as having acute lymphoblastic leukemia and treated with vincristine and prednisolone, resulting in remission. This case suggests that PV is a disease of multipotent stem cells including those with a lymphoid lineage.

Of 43 elderly patients who were suspected to have polycythemia between October 1990 and July 1998, 12 patients showed an increased red cell volume measured by 51Cr-labeled red blood cells. We analyzed the clinical characteristics of the 12 patients consisted of 7 men and 5 women, with a median age of 71 (range: 57-92). Chief complaints were headaches and dizziness (3 cases), symptoms of other conditions than polycythemia (4 cases). Five patients had no symptoms. Five of 6 patients over 70 years old had no symptoms due to polycythemia. Seven cases (58%) showed splenomegaly and three cases (25%) showed hepatomegaly. Laboratory findings were as follows: WBC 9.7 +/- 3.9 x 10(3)/microliter (mean +/- SD, p < 0.02 vs normal control), Hb 17.9 +/- 4.2 g/dl (p < 0.001), Plt 39.7 +/- 26.0 x 10(4)/microliter, EPO 13.8 +/- 5.2 mU/ml (p < 0.0001), NAP score 258 +/- 114, Vit. B12 1,686 +/- 2,156 pg/ml, arterial O2 saturation more than 92% in all cases. The diagnosis of all cases was polycythemia vera according to the diagnostic criteria of Polycythemia Vera Study Group. Associated conditions included 8 cases of thrombosis (cerebral thrombosis 4, thrombophrebitis 2, myocardial infarction 1, ischemic colitis 1) and 3 cases of malignancy (esophageal cancer 1, breast cancer 1, renal cancer 1), none of which was therapy-related cancer. Six patients (50%) had only phlebotomy, three (25%) only chemotherapy, and three (25%) both phlebotomy and chemotherapy. Patients over 80 years old needed neither intensive nor continuous treatment. Only one patient died due to esophageal cancer at age 89.

The chromosome aberration t(7;11)(p15;p15) is uncommon but recurrent in leukemia. We experienced a case of acute leukemia with t(7;11)(p15;p15), the hematological appearance of which mimicked myeloid crisis in chronic myeloid leukemia (CML). This case showed splenomegaly, a decreased neutrophil alkaline phosphatase (NAP) score, increased vitamin B12 value, and cells at all stages of neutrophilic maturation in both bone marrow and peripheral blood. We initially had difficulty differentiating acute myeloid leukemia (AML) M2 with marked myeloid differentiation from myeloid crisis of Philadelphia chromosome (Ph)-negative CML. Immature myeloid cells in the peripheral blood disappeared and cytogenetic analysis indicated that marrow cells changed to the normal karyotype after remission induction therapy. Therefore, this case was thought not to be myeloid crisis but AML M2 subtype. The NUP98/HOXA9 fusion transcript was detected by reverse transcription-polymerase chain reaction (RT-PCR) at exon A but not exon B of NUP98.
