Study of CD25 expression on leukemic cells: a prognostic factor in acute myeloid leukemia

were performed using Becton Dickinson, FACSCalibur flow cytometer equipped with Cell Quest software (USA) [ 14 , 15 , 16 ]. 2.1 Immunophenotyping analysis The detailed characterization of hematopoietic cells was done by analyzing the expression of a given set of antigens in a cell population. The applied panels of monoclonal antibodies (McAbs) for diagnosis of acute leukemia were as follows: primary panel: CD2 – phycoerythrin (PE); CD5 – PE; CD7 – fluorescein isothiocyanate (FITC); CD10 – FITC; CD19 – R-phycoerythrin (RPE); CD14 – FITC; CD13 – PE; CD33 – PE

The role of neuronal apoptosis inhibitory protein (NAIP) in acute myeloid leukemia patients

treatment failure. Disease-free survival (DFS) was calculated from the first day of CR until documentation of a relapse [ 3 ]. OS was calculated from the time of diagnosis until death [ 3 ]. Laboratory tests Blood and BM sampling Venous blood or BM samples were collected at the time of diagnosis into pyrogen-free ethylenediaminetetraacetic acid (EDTA) tubes. Immunophenotyping of leukemic cells was performed routinely in the whole peripheral blood or BM using flow cytometry: the “lysed-not washed” method. A routine panel of monoclonal antibodies HLA-DR, CD34, CD45

Clinical and laboratory features of Adult T-cell Leukemia/lymphoma (ATL): a study of 37 cases

, hematological findings, increased LDH value, detection of HTLV-I antibodies and immunophenotyping analyses. Four subtypes were used to classify the patients according to the classical criteria established by Shimoyama et al [ 39 ]. Morphology and Immunophenotyping Bone-marrow aspirate and/or Peripheral-blood were examined in all cases according to Catovsky et al (1984). Immunophenotyping analyses were performed routinely using a clean peripheral blood mononuclear cell (PBMC) from the patients, by flow cytometry using a panel of fluorochrome-conjugated monoclonal

Massive bone marrow necrosis associated with Waldenström’s macroglobulinemia

detected, with elevated IgM (6130 mg/dL) and relatively normal IgG and IgA levels (803 mg/dL and 136 mg/dL, respectively). BM examination revealed hypercellular marrow (nuclear cell count was 24.0 × l0 4 /mm 3 ) with 0/mm 3 megakaryocytes. Lymphoid cells were increased (80.8%) and were diffusely infiltrated into residual normal BM cells. The cells were small-to-medium-sized ones, with a high nucleus-to-cytoplasm (N/C) ratio and round-to-oval-shaped nuclei. An immunohistochemical study and flow cytometric (FCM) analysis demonstrated that the tumor cells were positive for

Retrospection of the effect of hydroxyurea treatment in patients with sickle cell disease

Asia, Indian subcontinent, and the Far East. Highest incidences of beta-thalassemia are found in populations of Cyprus (14%), Sardinia (12%), and Southeast Asia [ 5 ]. Alpha-thalassemia is more common in sub-Saharan Africa, the Mediterranean Basin, the Middle East, South Asia, and Southeast Asia [ 6 , 7 , 8 , 9 ]. In SCA, the deformed RBCs tend to get stuck in narrow blood capillaries and block the blood flow. Patients experience vaso-occlusive crisis (VOC) in their joints and bones, along with severe pain, which causes multiple organ damage ( Figure 2 ) in SCD

Diagnostic approach to light-chain cardiac amyloidosis and its differential diagnosis

:3. Bone marrow biopsy in AL amyloidosis may reveal an increased percentage of plasma cells that may appear morphologically normal, with a median percentage of <10% [ 25 ]. Immunoperoxidase staining or flow cytometric analysis of specimens of the involved bone marrow can demonstrate clonal excess of plasma clone cells. Bone marrow biopsy is 50% sensitive for detecting deposits of amyloid, but, performed with fat pad aspirate, can be up to 85% sensitive [ 26 ]. Cardiac biomarkers Biomarker-based staging systems are crucial for patient stratification in clinical

Plerixafor for patients who fail cytokine-or chemotherapy-based stem cell mobilization: Results of a prospective study by the Polish Lymphoma Research Group (PLRG)

the peripheral blood was < 10/μL 4-6 days after the onset of G-CSF administration as monotherapy or within 20 days after the onset of administration of chemotherapy in combination with G-CSF. For the decision to start leukaphereses the number of circulating CD34 + cells was first evaluated on the second day of neutrophil recovery > 1 × 10 9 /L in patients who experienced grade 3 or 4 neutropenia or, in the remaining patients, on the first day with increase of neutrophil count. The analysis was done using flow cytometry, according to local protocols

Prognostic value of soluble angiotensin II receptor 1 and soluble angiotensin converting enzyme (CD 143) in patients with acute leukemia

peripheral blood. Evaluation for morphology, flow cytometry, immunophenotyping and cytogenetic testing is valuable both for confirming the diagnosis and risk stratification. Lumbar puncture with CSF analysis is standard of care at the time of diagnosis to evaluate for CNS involvement. If the CNS is involved, brain MRI should be performed. Other evaluation includes complete blood count with differential and smear to evaluate the other hematopoietic cell lines, coagulation profiles and serum chemistries. Baseline uric acid, calcium, phosphate and lactate dehydrogenase should
