BACKGROUND: Fluorescent aerolysin (FLAER) has been recommended as an important part of antibody panel used for flow cytometric detection of paroxysmal nocturnal hemoglobinuria (PNH) clone. This study was aimed to observe the frequency of PNH-positive clones and their sizes in patients screened for various indications. METHOD: A retrospective analysis of 624 patients screened over a period of 30 months. Frequency and size of clone sizes noted, and laboratory parameters were compared among different groups of patient being screened...

INTRODUCTION: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disease and can present as a wide range of signs and symptoms. As such, the indication for diagnostic testing for PNH is not always straightforward. Therefore, we analyzed all first-time samples tested over a 56-month period to determine the clinical settings with a high probability of detecting a PNH clone. METHODS: We retrospectively analyzed 323 first-time PNH flow cytometry tests, including LDH, cytopenias, direct antiglobulin test (DAT), and clinical indication for testing as available at the time of testing...

The clinical presentation of myelodysplastic syndrome (MDS) is not specific. Many patients can be asymptomatic and can be detected only due to an abnormal complete blood cell count (CBC) on routine exam or for other reasons while others can be symptomatic as a consequence of underlying cytopenias. Thrombotic thrombocytopenic purpura (TTP) usually is suspected under the evidence of microangiopathic hemolytic anemia (MAHA) and thrombocytopenia and because it is a life-threatening condition (medical emergency) immediate initiation of plasmapheresis could be life-saving...

Thrombotic microangiopathy (TMA) is a rare but lethal multisystem disease characterized by peripheral thrombocytopenia, microangiopathic hemolytic anemia, fever, and various stages of renal and neurological dysfunctions.(1,2)) The causes of TMA are mainly thrombotic thrombocytopenic purpura (TTP) or hemolytic-uremic syndrome (HUS), and cases of TMA related to myelodysplastic syndrome (MDS) are quite rare. Herein, we report a case of acute myocardial infarction (AMI) caused by TMA which is strongly suspected to have a relationship to MDS, and discuss the treatment of our patient who needed antiplatelet or anticoagulant therapy after AMI, while on the other hand, had pancytopenia and a bleeding event due to MDS...

BACKGROUND: Although consensus guidelines have been proposed in 2010 for the diagnostic screening of paroxysmal nocturnal hemoglobinuria (PNH) by flow cytometry (FCM), so far no study has investigated the efficiency of such medical indications in multicentric vs. reference laboratory settings. METHODS: Here we evaluate the efficiency of consensus medical indications for PNH testing in 3,938 peripheral blood samples submitted to FCM testing in 24 laboratories in Spain and one reference center in Brazil...

Myelodysplastic syndrome (MDS) is a clonal stem-cell disorder characterized by dyshematopoiesis. We report a patient who presented with cytopenias and microangiopathic hemolytic anemia. Chromosome microarray analysis (CMA), using single nucleotide polymorphism arrays, on peripheral blood revealed genomic imbalances indicative of MDS, which was confirmed by bone marrow examination. This report highlights the importance of suspecting MDS in patients with cytopenias and microangiopathic hemolytic anemia. CMA of peripheral blood may assist in the preliminary diagnosis of MDS, representing a comparatively less invasive diagnostic procedure and may aid bone marrow evaluation when an aspirate sample is insufficient for conventional cytogenetic analysis...

The percentage manifesting dysplasia in bone marrow needed to qualify as significant is ≥10 % in each lineage. However, detailed analyses of this threshold have not been reported. Here, we analyzed dyserythropoiesis (dysE) in 109 myelodysplastic syndromes (MDS) patients with 21 immune thrombocytopenia (ITP)/12 hemolytic anemia (HA) patients as a control. In present study, mild megaloblastic erythroblasts were specifically named 'red cell with abnormal chromatin clumping (RCACC)'. RCACC ≥10 % in erythroblasts was observed in 29 % of ITP patients and 58 % of HA patients...

Myelodysplastic syndrome (MDS) is known to often be complicated by a range of autoimmune diseases. We herein present a case with MDS complicated by cold autoimmune hemolytic anemia (cold AIHA). The patient was a 51-year-old woman. She was diagnosed with MDS (refractory cytopenia with multilineage dysplasia) in May 2009. In January 2010, she underwent unrelated allogeneic bone marrow transplantation but was re-admitted in October 2010 for treatment of relapsed MDS. Despite daily transfusions of red blood cells, her anemia failed to improve...

Suicidal erythrocyte death (eryptosis) is characterized by cell shrinkage, cell membrane blebbing, and cell membrane phospholipid scrambling with phosphatidylserine exposure at the cell surface. Eryptotic cells adhere to the vascular wall and are rapidly cleared from circulating blood. Eryptosis is stimulated by an increase in cytosolic Ca(2)+ activity, ceramide, hyperosmotic shock, oxidative stress, energy depletion, hyperthermia, and a wide variety of xenobiotics and endogenous substances. Inhibitors of eryptosis include erythropoietin and nitric oxide...

Previously, we described a group of patients with hemocytopenia who did not conform to diagnostic criteria of known hematological and nonhematological diseases. Most patients responded well to adrenocortical hormone and/or high-dose intravenous immunoglobulin treatment, indicating that cytopenia might be mediated by autoantibodies. Autoantibodies were detected on the membrane of various bone marrow (BM) hemopoietic cells by bone marrow mononuclear-cell-Coombs test or flow cytometric analysis. Thus, the hemocytopenia was termed "Immunorelated Pancytopenia" (IRP) to distinguish it from other pancytopenias...

Ectopic extramedullary hematopoiesis (EMH), defined as the formation of blood cells outside the bone marrow, usually occurs in a scenario of chronic anemia when, even after conversion of the bony yellow marrow to red marrow, the body is still unable to meet the demand for red blood cells. Ectopic extramedullary hematopoiesis most commonly occurs in the liver and spleen but may, in fact, occur almost anywhere in the body. Although previous reports have documented EMH presenting as paraspinal masses, such lesions have almost always been associated with a predisposing hematological disorder such as hemolytic anemia, myelofibrosis or myelodysplastic syndromes, thalassemia, polycythemia vera, leukemia, or lymphoma...

Late-onset erythropoietic protoporphyria (EPP) is rare, and it is usually associated with an acquired somatic mutation of the ferrochelatase gene secondary to hematological malignancy such as myelodysplastic syndrome or myeloproliferative disorder. In 0.5-1% of patients with EPP, deposition of protoporphyrin in the liver leads to progressive liver insufficiency. Herein, we report the case of a 67-year-old female who developed EPP with typical photosensitivity and hemolytic anemia. Six months later, she was admitted with acute liver damage with a rapidly progressing course, and developed liver insufficiency...

Anemia in IBD is the result of a combination of iron deficiency and anemia of chronic disease. Therapy of IBD is relief of inflammation, but the drugs usage may cause the development hemolytic anemia and myelodysplastic syndrome. We studied the effect of basic therapy on the incidence of anemia and assess the impact of modern biological therapies on the main markers of AHZ. A total of 153 patients with ulcerative colitis (UC) and 53 patients with Crohn's disease (CD), which at the time of the study received basic anti-inflammatory therapy for at least 1 year...
