The determination of leukocyte alkaline phosphatase (LAP) is used as an aid to diagnose many diseases in the laboratory. For example, it can be used to distinguish chronic myeloid leukemia (CML) from other myeloproliferative disorders (particularly myelofibrosis and polycythemia) and leukemoid reactions (LR). Traditionally, this test is performed with the use of subjective cytochemical assays that assign a score to the level of LAP. Here we present a nonsubjective, quantitative, sensitive, and inexpensive chemiluminescent technique that determines LAP based on the commercial reagent Immulite (AMPPD)...

The PRAME (preferentially expressed antigen of melanoma) gene has been shown to be expressed in high levels in some solid tumors and hemopoietic neoplasias but not or only weakly expressed in normal tissues. It encodes an antigen recognized by autologous cytolytic T lymphocytes. PRAME is a good candidate for tumor immunotherapy and is a useful marker gene for detection of minimal residual disease (MRD). In this study, PRAME mRNA using real-time RT-PCR was studied in 74 adult cases with acute leukemia-68 had de-novo acute leukemia, 3 had chronic myeloid leukemia-blastic crisis (CML-BC), and 3 had myelodysplastic/myeloproliferative syndrome-blastic transformation (MDS/MPD-BT)-and the results were compared with 30 age-matched healthy volunteers...

A 69-year-old man was found to have leukocytosis and a bleeding tendency, when he underwent surgery for hemorrhoids in November 1992, at the age of 69. The patient was referred to our department for further examination, and was admitted on December 4. On admission, he had hepatomegaly (5 cm) and splenomegaly (12 cm). Laboratory data on admission showed that the leukocyte count was 173,400/microliter, erythrocyte count, 314 x 10(4)/microliter, hemoglobin level, 10.5 g/dl, hematocrit value, 29.7%, and platelet count, 14...

A 58-year-old male presented with fatigue, tiredness, and pruritus after hot showers and an elevated white blood cell count (20000/mm(3)). A diagnosis of polycythemia vera (PV) was made after investigation revealed a low erythropoietin and elevated leukocyte alkaline phosphatase (LAP) score; he was treated with repeated phlebotomies. Two years later he developed elevated white counts again and investigation revealed Philadelphia chromosome positive (19/20 cells) chronic myelocytic leukemia (CML). The karyotype also revealed trisomy 9 in 1 of 20 cells...

Chronic myeloprolifeative diseases (CMPD) are clonal hematopoietic stem cell disorders characterized by excessive proliferation and production of one or more of the myeloid cells and are subclassified according to the predominant cells, such as chronic myelogenous leukemia (CNL), chronic eosinophilic leukemia (CEL), polycythemia vera (PV), essential thrombocythemia (ET) and chronic idiopathic myelofibrosis (CIMF). This brief review focuses on the characteristic morphology of each clinical entity and the useful cytochemical (including leukocyte alkaline phosphatase, myeloperoxidase, butyrate esterase, chloroacetate esterase and cyanide-resistant peroxidase) and immunohistochemical (including von Willebrand factor/CD61, keratin, tryptase, CD117, CD68 (PGM-1), c-Mpl and bFGF) stains for differential diagnosis...

Chemical agents such as mustard gas (or sulfur mustard), which has alkylating characteristics, were used against Iranian combatants in the Iraq-Iran war. Previous studies have not shown a strong link between these chemical agents and the development of chronic myelocytic leukemia (CML). The purpose of this study was to evaluate the increased risk of CML development in Iranian soldiers exposed to mustard gas during the war. Based on a descriptive study of 2,500 cases with documented exposure to various chemical warfare agents, 665 patients had documented exposure to mustard gas...

Leucocyte alkaline phosphatase (LAP) is a marker of post-mitotic granulocytes and its activity is reduced or absent in chronic myelogenous leukaemia (CML) granulocytes as a consequence of LAP messenger RNA (mRNA) deficiency. We provide evidence that along the granulocytic maturation in normal marrow, the acquisition of LAP surface expression, identified by the monoclonal antibody 1B12.1, was restricted to CD11bbright/CD16bright positive cells. Moreover, in normal granulocytes, exposure to granulocyte colony-stimulating factor (G-CSF) in vitro and in vivo increased the cell surface expression of LAP...

A 78-year-old man was diagnosed as leukocytosis in February 1994. Physical examination revealed marked hepatosplenomegaly. A peripheral blood examination disclosed 95,090/microliter leukocytes without hiatus leukemicus, 6.5 g/dl Hb, and 15.0 x 10(4)/microliter platelets. The neutrophil alkaline phosphatase score was 27, and serum VB12 was above 1,600pg/ml. IgG was identified as monoclonal immunoglobulin of type lambda. Bone marrow specimens demonstrated marked granulocytic hyperplasia. Neither the Philadelphia chromosome (Ph1) nor BCR gene rearrangement was detected; hence, the diagnosis of Ph1 (-) chronic myeloid leukemia (CML) was made...

We report a case of acute febrile neutrophilic dermatosis, Sweet's syndrome, associated with chronic myelogenous leukemia (CML) in which we found rearrangement of the bcr gene in DNA obtained from a skin lesion as well as in blood DNA by Southern blot analysis. This indicated the presence of CML cells within the skin lesion. To our knowledge, this is the first report in which the presence of CML cells is shown within skin lesions of Sweet's syndrome. In our patient, leukocyte alkaline phosphatase activities returned to normal levels when he was suffering from Sweet's syndrome and decreased again to below normal levels after it subsided...

Although a breakpoint in the minor breakpoint cluster region (m-bcr) of the BCR gene is observed in about two-thirds of patients with Philadelphia chromosome-positive acute lymphoblastic leukemia, this type of genomic rearrangement occurs very rarely in chronic myeloid leukemia (CML). We describe here the eighth case of m-bcr CML, and delineate unique clinical characteristics found in common to the 7 cases reported previously. Monocytosis with a low neutrophil/monocyte ratio resembling chronic myelomonocytic leukemia was the most striking feature of m-bcr CML...

Using flow cytometry, we quantitatively examined the density of the CD16 (IgG Fc receptor III) antigen on neutrophils in healthy control subjects, in patients with neutrophilia due to bacterial infection, and in patients with chronic myeloproliferative disorders (chronic myeloid leukemia [CML], polycythemia vera, or essential thrombocythemia). The density was expressed as the mean fluorescence intensity of neutrophils stained with fluorescein isothiocyanate-labeled anti-CD16 monoclonal antibody. We also determined leukocyte alkaline phosphatase activity semiquantitatively in the same population...

Leucocyte alkaline phosphatase (LAP) is an enzyme expressed on the external aspect of the neutrophilic granulocyte plasma membrane, and represents a specific marker for the fully differentiated granulocyte. In this report we characterize 1B12.1, a monoclonal antibody raised against human bone alkaline phosphatase, by its ability to recognize the LAP protein. As assessed by Western blot analysis, following electrophoresis under non-reducing conditions, the antibody specifically reacts with LAP upon forced expression of the protein in simian COS-7 fibroblasts...

The rhG-CSF had specificity of stimulation proliferation and differentiation of the neutrophil lineage in which there was an increase of younger stages, the earliest was myelocyte, of granulocyte in circulation. The effect of it was demonstrated within 24 hours of administration and reduced immediately after withdrawal. LAP activity in this condition was normal. The pattern of hematologic change in this condition may mimic CML and leukemoid reaction. It differed clearly from CML, since LAP activity in CML was lower than normal, but LAP activity could not define it from leukemoid reaction...

COMPARATIVE STUDY
L DePalma, P Delgado, M Werner
Decreased leukocyte alkaline phosphatase (LAP) is a first line test for chronic myelogenous leukemia (CML), generally preceding a diagnostic algorithm which also includes bone marrow biopsy, cytogenetic analysis, and molecular diagnostics. We found the analytical uncertainty of LAP assays to range from over 100% coefficient of variation at low scores to about 20% at high scores. However, the receiver-operator characteristics derived from LAP determinations in 50 consecutive cases suggest that a suitably high diagnostic decision threshold still can eliminate false negatives...

Trisomy 13, as a sole karyotypic abnormality in acute leukemia, has been reported in several cases. However, in chronic myelogenous leukemia (CML), only two cases with this abnormality were reported so far. We describe herein a 68-year-old case with Philadelphia chromosome-negative CML and trisomy 13. Leukocytosis was pointed out during the treatment for other diseases. After 7 months, abrupt increase in leukocyte count (108,000/microliters) and splenomegaly developed. Decreased neutrophil alkaline phosphatase activity and morphological features fulfilled the diagnostic terms for CML...
