BACKGROUND: Pure red cell aplasia (PRCA) is a well-documented potential side effect of ABO major mismatched allogeneic hematopoietic stem cell transplants. This side effect may be self-limiting, but is sometimes treated using modalities such as steroids, antithymocyte globulin, donor lymphocyte infusions, rituximab, or plasma exchanges. Another well-documented cause of pure red cell aplasia is a chronic parvovirus B19 infection, which may be seen in immunocompromised hosts. The treatment of this cause of PRCA includes removal of immunosuppression, intravenous immunoglobulin (IVIg), or rituximab; however, this condition may also be self-limiting...

Hereditary spherocytosis (HS) is a disease affecting the red blood cells membrane and belongs to the congenital hemolytic anemias. The clinical spectrum ranges from asymptomatic patients to severe forms requiring transfusions in early childhood. The diagnosis can be based on the physical examination, complete red blood cell count, reticulocytes count, medical history and specific tests, preferentially the EMA test (eosin-5-maleimide binding) test and AGLT (Acidified Glycerol Lysis Time). Splenectomy is considered the standard surgical treatment in moderate and severe forms of hereditary spherocytosis...

In Southeast Asia, particularly in Thailand, β0-thalassemia/hemoglobin E (HbE) disease is a common hereditary hematological disease. It is associated with pathophysiological processes, such as the intramedullary destruction of immature erythroid cells and peripheral hemolysis of mature red blood cells. MicroRNA (miR) sequences, which are short non-coding RNA that regulate gene expression in a suppressive manner, serve a crucial role in human erythropoiesis. In the present study, the plasma levels of the erythroid-expressed miRNAs, miR‑451 and miR‑155, were analyzed in 23 patients with β0-thalassemia/HbE and 16 control subjects...

BACKGROUND: Hemolytic transfusion reactions and transfusion-related acute lung injury (TRALI) are life-threatening complications associated with the transfusion of blood products. Hemorrhage is one of the most common surgical complications and the risk of bleeding is particularly acute in patients with hematologic deficiencies. Management of surgical bleeding can be divided into two phases. The first phase centers on immediate control of acute bleeding and the second phase focuses on keeping the patient stable and on reducing the sequelae associated with blood transfusions and blood loss...

CXCL10/IFN-γ-induced protein 10 (IP-10) and its corresponding receptor CXCR3 have long been considered to be involved in the pathophysiology of type 1 T (Th1) cell-orientated autoimmune diseases. However, the exact role of CXCL10 in the pathogenesis of aplastic anaemia (AA) has not been thoroughly studied. The aim of our study was to evaluate the plasma level of CXCL10 and its effects on CD4(+) T cell differentiation in AA. In our study, we found that an elevated plasma level of CXCL10 was negatively correlated with platelet, absolute neutrophil and reticulocyte counts, while it was positively correlated with the proportion of lymphocytes in white blood cells in AA patients...

BACKGROUND: Sickle cell anemia (SCA) patients exhibit sub-phenotypes associated to hemolysis and vaso-occlusion. The disease has a chronic inflammatory nature that has been also associated to alterations in the lipid profile. This study aims to analyze hematological and biochemical parameters to provide knowledge about the SCA sub-phenotypes previously described and suggest a dyslipidemic sub-phenotype. METHODS: A cross-sectional study was conducted from 2013 to 2014, and 99 SCA patients in steady state were enrolled...

BACKGROUND: Blood trauma caused by continuous-flow left ventricular assist devices (CF-LVADs) has been associated with device thrombosis and anemia. Accurate in vivo quantification of erythrocyte turnover and its contribution to CF-LVAD complications have yet to be elucidated. METHODS: We investigated the age (lifespan) of circulating erythrocytes in subjects with CF-LVAD. Erythrocyte lifespan is a quantitative indicator of in vivo erythrocyte turnover that can be accurately derived from measurement of the exhaled carbon monoxide (CO) level...

OBJECTIVE: The immature platelet fraction (IPF) is a laboratory measurement analogous to the reticulocyte count, but reflecting the thrombopoietic state. Similar to a reticulocyte count, it can be expressed as a percent (IPF%=percent of platelets that are immature) or as an absolute number per μl blood; the immature platelet count (IPC=IPF% × platelets per μl of blood). STUDY DESIGN: Using a retrospective analysis of de-identified data from non-thrombocytopenic neonates, we created reference intervals for IPF% and IPC...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disease, especially in children, characterized by intravascular hemolysis, thrombotic events, serious infections and bone marrow failure. We describe 16 patients who were diagnosed with PNH in childhood or adolescence. The time interval between the onset of symptoms and the PNH diagnosis and its treatment were compared in patients with classic PNH versus PNH associated with bone marrow disorder (PNH/BMD). A greater delay in diagnosis was observed in classic PNH compared to PNH/BMD patients...

BACKGROUND: Passenger lymphocyte syndrome occurs when donor lymphocytes are transplanted with a solid organ and produce alloantibodies that react with antigens on the recipient's red blood cells (RBCs). Typically, passenger lymphocyte syndrome presents as immunoglobulin G antibody-mediated, extravascular hemolytic anemia with reticulocytosis. Often, the donor was alloimmunized before transplantation. CASE REPORT: A 34-year-old Group O, D+ man with a negative antibody screen received a liver transplant from a Group O, D- donor...

The clinical course of hemoglobin H (HbH) disease is remarkably variable. It is not completely clear how genetic and environmental factors interplay to modify clinical severity in affected individuals. Previous studies suggested that altered structure or function of alpha-hemoglobin-stabilizing protein (AHSP) could modify the clinical phenotypes of thalassemias. The present study attempted to explore the potential role of AHSP in the pathophysiology of HbH disease in 95 Chinese and Thai/Sino-Thai patients with deletional and non-deletional form of this disease...

Congenital erythrocytosis (CE) is a rare and heterogeneous disease. The high oxygen affinity hemoglobin (Hb) variants are the most common cause of CE. Herein, we report a Korean patient with isolated erythrocytosis. A 25-year-old man was referred to our hospital for evaluation of high Hb level (Hb 20.4 g/dL, hematocrit 58%, reticulocyte count 2.90%, white blood cell count 6.83×10⁹/L, and platelet count 195×10⁹/L). Bone marrow biopsy revealed normocellular marrow without myeloproliferative features. JAK2 (V617F, exon 12), CALR (exon 9), and MPL W515K/L mutations were not detected...

Evaluation of parameters relating to serum ferritin and iron is critically important in the diagnosis of iron deficiency anemia (IDA). The recent development of automated systems for hematology analysis has made it possible to measure reticulocyte hemoglobin equivalent (RET-He), which is thought to reflect iron content in reticulocytes, in the same sample used for complete blood count tests. If RET-He is, indeed, capable of evaluating iron deficiency (ID), it would be useful for immediate diagnosis of IDA. In the present study, we examined the usefulness of RET-He for diagnosis of ID...
