The diagnostic value of the Alkaline Leucocyte Phosphatase (ALP) was checked on the basis of the patients of a hematologic department. Reliable data can only be obtained for the differential diagnosis of polycythemia vera and secondary polycythemia, not however for the differential diagnosis of chronic myeloid leukemia (CML) and myelofibrosis. In CML the ALP is an aid for evaluating the course of the disease and its remissions. In Hodgkin's disease it is an objective parameter for actiivty of the disease. The leucocyte concentration method can be used for evaluation of the ALP.

A 10-year-old boy, who had been in an uninterrupted remission of acute lymphocytic leukemia (ALL) for six years, developed polycythemia vera (PV). One and a half months after detection of PV, he was found to have active leukemia. Both the polycythemia and leukemia receded with anti-leukemia therapy. Three possible explanations for the development of PV in a child with ALL are discussed: 1) PV was a part of his original ALL and recurred whtn patient relapsed. The PV phase was detected only during relapse because the patient was under close observation. 2) PV was a second neoplasm independent of ALL. 3) PV was part of a second leukemia which was different from the original leukemia; this new ALL was derived from a pluripotential cell line involving both erythroid and lymphoid elements. A precedent for this explanation has been observed in chronic myelogenous leukemia.

Ten clinical observations concerning six families with familial myeloproliferative disorders are reported. Family no. 1 : two brothers, RES with myelosclerosis and ROS with chronic myeloid leukemia. Family no. 2 : PG atypical myeloproliferative syndrome and his brother polycythemia vera. Family no. 3 : DF myelosclerosis and her son (DR) polycythemia vera. Family no. 4 : DM, polycythemia vera, the mother and a sister with splenomegaly. The brother died with myelofibrosis. Family no. 5 : GA and ML, cousins with polycythemia vera. Family no. 6 : MB and ZG, a brother and sister with polycythemia vera. No consanguinity and no toxic, infections or malignant etiology were found in these families. The literature reviewed emphasises the rarity of the familial incidence of myeloproliferative disorders.

Since the discovery of a very high blood histamine level in chronic myelocytic leukemia (CML) 1936, the author could ascertain that this parameter is very useful in the differential diagnosis between CML and various "leukemoid" reactions; in the early diagnosis of CML and in the differential diagnosis between CML and other myeloproliferative disorders. Recent researches proved that no correlation exists between blood histamine level and basophil count in the peripheral blood. Further investigations in this field have to clear up the questions whether it is possible by means of repeated controls of the blood histamine level to predict the development of a polycythemia vera into CML or to establish in a case of osteomyelosclerosis that this disease has been Preceeded by A CML.

Because of recent developments in the study of vitamin B12-binding proteins, the levels of the three serum binders were compared in serum and plasma samples from subjects with various disorders. The results allow the following conclusions: (1) As previously reported, transcobalamin (TC) III and to a lesser extent TC I are artifactually elevated in serum. The appear to be released in vitro during the clotting process, presumably from granulocytes. (2) Blood cells of patients with polycythemia vera release exceedingly large amounts of TC I and TC III in vitro. (3) The above findings support, but do not prove, at least a partial granulocytic source of TC I. Nevertheless, factors other than granulocytes influence TC I levels, as disorders characterized by increased TC I (most prominently chronic myelogenous leukemia but also several cases of cancer) manifest relatively little cellular release of TC I in vitro. (4) Despite the serum artifact, the serum abnormalities described in various conditions were seen in plasma also, even though the actual values of themselves were lower in plasma. The chief exception was TC III, which was elevated in plasma only in polycythemia vera (and in a few cases of leukocytosis). (5) EDTA-NaF anticoagulant is not suitable, as it causes plasma dilution, thus explaining previous reports of TC II level differences between serum and plasma. EDTA is therefore a preferable anticoagulant for vitamin B12-binding protein studies, although it too may not be ideal.

Reports of heterogeneity of IgG receptor activity of normal circulating neutrophils prompted measurements in myeloproliferative disease to determine if dysplasia of the hematic stem cell resulted in an abnormality of this membrane property. IgG receptors were assayed by rosette formation in suspension with human Rh-positive erythrocytes sensitized with high-titer Rh antiserum. IgG receptors were detected on 19 +/- 1.6% (mean +/- SEM) of neutrophils from 45 normal subjects. A significant increase in IgG-receptor-bearing neutrophils was found in polycythemia vera (PV) and myeloid metaplasia (MyM), with values of 70 +/- 3.6% and 69.7 +/- 4.3%, respectively. Normal values were observed in polycythemic states not due to myeloproliferative disease and in chronic myelocytic leukemia. Rosette-forming neutrophils were increased to 52.3 +/- 3.7% in infection and inflammatory disease, but this value was significantly lower than those in PV and MyM. Increased IgG receptors in PV and MyM may be related to the activated state of the neutrophil and may result from an intrinsic cellular abnormality of the proliferating clone or from altered bone marrow release. Quantitation of neutrophil IgG receptors may be of value in the differential diagnosis of PV and MyM and may offer insights into the derangement of hematopoiesis that underlies these myeloproliferative disorders.

32P is effective therapy for polycythemia and primary thrombocytosis. The Polycythemia Vera Study Group is comparing radioactive phosphorus with alkylating agents to determine relative efficacy. Less well investigated is the effectiveness of 32P vs. busulfan in chronic granulocytic leukemia. Endolymphatic administration of radiopharmaceuticals may play a role in the therapy of infradiaphragmatic lymphoma. Among the radionuclides that have at times been used in hematology are 32P, 198Au 24Na, 76As, 89Sr, 52Mb, 54Mn, 91Y, 95Zr, 95Cb, 111Ag, 109Pd, 131I, 185W, and 192Ir. As stated, 32P has proven single most efficacious agent. The hematologic diseases that have been treated include both malignant and benign conditions. Among the malignant conditions are polycythemia vera, agnogenic myeloid metaplasia, thrombocythemia, leukemia, Hodgkin's disease, and multiple myeloma. Hemophilia, and Osler--Weber--Rendu disease are among the benign entities in which the agents have been tried. Polycythemia and thrombocythemia remain those in which the greatest success has been achieved.

The utility of the enzymatic radiochemical assay of histamine in diagnosing diseases with known abnormalities in histamine production was investigated. Whole blood histamine levels were abnormal only in patients with basophilia, i.e. chronic myelocytic leukemia or polycythemia vera. Histamine was not detectable (less than 1 ng/ml) in normal plasma but was detected in plasma of some patients witheither mastocytosis or chronic myelocytic leukemia. These patients also had symptoms which could be attributed to histamine release as, for example, hyperchlorhydria and hypotension. Urinary histamine excretion was also abnormally high in these diseases compared to normal subjects (range less than 5-42 microgram/24 h, n = 31). Patients with systemic mastocytosis had higher urine values (greater than 150 microgram/24 h) than those with cutaneous mastocytosis (39-88 microgram/24 h), and the urinary histamine excretion appeared to be an index of the severity of the diseases. Studies with L-histidine loading suggest that the kidney is one possible source of urinary histamine.

The technique described in the preceding paper was applied to 12 abnormal sera selected for their increase in one or more B12-binding proteins. Even in the presence of large amounts of R-type binder, the ammonium sulfate technique gave a reliable separation of R binding proteins from TC II. Measurement of the TC II in abnormal sera gave results identical to those obtained by the more standard gel filtration. The R binders of four subjects with myeloproliferative disease were further separated into alpha2-R and alpha1-R. The pattern of B12 binding of polycythemia vera (PV) was an exaggeration of the normal pattern. Binding to alpha2-R was three to four times that to alpha1-R, although the total amounts bound to both were increased. In chronic myelogenous leukemia (CML), both alpha2-R and alpha1-R were also increased, but in contrast to binding in normal sera, alpha1-R predominated. In order to interpret the findings, either whole serum R or alpha1-R and alpha2-R from patients with myeloproliferative disease were subject to isoelectric focusing. Alpha2-R consisted pricipally of components isoelectric at pH 2.9, 3.0, and 3.1. These components were present in only minor amounts in normal serum and were somewhat increased in the serum of PV. These components were very much increased in the serum of CML and predominated. Alpha2-R consisted of those components isoelectric at pH 3.4,3.6, and 4.0. These components predominated in the unsaturated binding capacity of normal sera and that of PV. It was concluded that the division of plasma R binders into alpha1-R and alpha1-R by the technique described provided information useful in the study of myeloproliferative diseases.

Chronic granulocytic leukemia developed in a 59-year-old woman who had previously received a total of 21 mCi -32P for polycythemia vera. She was treated with Myleran (busulphan) for her chronic granulocytic leukemia. Cytogenic studied revealed deletion of chromosomes No. 8 and 12, and translocation between 1 and 8. The patient also developed a severe antoimmune hemolytic anemia, for which she received prednisone treatment. She died with a perforated stomach ulcer.
