The effect of spaceflight on red blood cell mass (RBCM), plasma volume (PV), erythron iron turnover, serum erythropoietin, and red blood cell (RBC) production and survival and indexes were determined for six astronauts on two shuttle missions, 9 and 14 days in duration, respectively. PV decreased within the first day. RBCM decreased because of destruction of RBCs either newly released or scheduled to be released from the bone marrow. Older RBCs survived normally. On return to Earth, plasma volume increased, hemoglobin concentration and RBC count declined, and serum erythropoietin increased. We

Abstract Autoimmune hemolytic anemia (AIHA) due to warm-acting IgA autoantibodies is rare. We explored the pathogenic mechanisms underlying destruction of red blood cells (RBCs) in a patient with severe AIHA mediated exclusively by polymeric immunoglobulin A (pIgA) anti-Band 3 autoantibodies. The follow-up period was 17 months. RBCs were not destroyed by complement activation as no deposition of complement was observed on the patient's RBCs. pIgA eluted from the patient's RBCs did not induce RBC destruction through phagocytosis by monocytes or antibody–dependent cell–mediated cytotoxicity by n

Abstract Abstract 716 In autoimmune hemolytic anemia (AIHA) autoantibodies (auto-Ab's) to red blood cells (RBCs) may induce complement activation via the classical pathway of complement resulting in complement deposition on RBCs. RBCs coated with auto-Ab and/or complement (C3b) are removed by extravascular destruction in the spleen and liver. In a minority of cases complement activation proceeds until insertion of the membrane attack complex (MAC) resulting in intravascular hemolysis. The inflammatory response and the anoxia induced by hemolysis significantly contribute to the morbidity and fa

Abstract EndoS from Streptococcus pyogenes is an immunomodulating enzyme that specifically hydrolyzes glycans from human immunoglobulin G and thereby affects antibody effector functions. Autoimmune hemolytic anemia is caused by antibody-mediated red blood cell (RBC) destruction and often resists treatment with corticosteroids that also cause frequent adverse effects. We show here that anti-RhD (anti-D) and rabbit anti–human-RBC antibodies (anti-RBC) mediated destruction of RBC, ie, phagocytosis, complement activation, and hemolysis in vitro and in vivo was inhibited by EndoS.

Abstract During acute falciparum malaria infection, red blood cells (RBC) containing abundant ring-infected erythrocyte surface antigen (Pf 155 or RESA), but no intracellular parasites, are present in the circulation. These RESA-positive parasite negative RBC are not seen in parasite cultures in vitro. This indicates that in acute falciparum malaria there is active removal of intraerythrocytic parasites by a host mechanism in vivo (probably the spleen) without destruction of the parasitized RBC. This may explain the observed disparity between the drop in hematocrit and decrease in parasite cou

Abstract Inactivating mutations in divalent metal transporter 1 (DMT1) are associated with a severe defect in erythroid iron utilization and cause moderate to severe hypochromic microcytic anemia in human patients and two rodent models.

Athletes engaged in dynamic sports experience a shortened red blood cell (RBC) lifespan and accelerated turnover due to RBC destruction. This accelerated RBC turnover might have a positive impact on exercise performance by increasing the number of young red blood cells with a high oxygen-carrying capacity. However, accelerated turnover might also be a result of intravascular haemolysis caused by RBC destruction during exercise, impairing RBC function and oxygen transport. Therefore, we aimed to evaluate the relationship between reticulocyte count as an indicator of short-term RBC profile chang

Human red blood cells (RBCs) are normally phagocytized by macrophages of splenic and hepatic sinusoids at 120 days of age. The destruction of RBCs is ultimately controlled by antagonist effects of phosphatidylserine (PS) and CD47 on the phagocytic activity of macrophages. In this work, we introduce a conceptual model that explains RBC lifespan as a consequence of the dynamics of these molecules. Specifically, we suggest that PS and CD47 define a molecular algorithm that sets the timing of RBC phagocytosis. We show that significant changes in RBC lifespan described in the literature can be expl

Hemolysis is a fact in all extracorporeal circuits, as shown in various studies by the increasing levels of plasma-free hemoglobin (PfHb) and decreasing levels of haptoglobin during and after cardiopulmonary bypass (CPB). Beside complete red blood cell (RBC) destruction or hemolysis, RBCs can also be damaged on a sublethal level, resulting in altered rheological properties. Increased levels of free RBC constituents together with an exhaust of their scavengers result in a variety of serious clinical sequela, such as increased systemic and pulmonary vascular resistance, altered coagulation profi

Activated neutrophils at effector/target ratios of 1:20 to 1:2,000 induced depletion of red blood cell (RBC)-reduced glutathione, increased membrane-bound hemoglobin and methemoglobin, and promoted immunoglobulin binding to the cell membrane. Superoxide dismutase/catalase ameliorated the decrease in reduced glutathione and the increase in methemoglobin and immunoglobulin binding. This is interpreted as evidence that activated neutrophils can alter the antigenic nature of the RBC membrane through generation of toxic oxygen radicals.

Autoimmune hemolytic anemia (AIHA) is a disease in which autoantibodies against red blood cells (RBCs) lead to their premature destruction. Most clinically significant autoantibodies are of the immunoglobulin G (IgG) type, which leads primarily to the uptake and destruction of RBCs by splenic and hepatic macrophages. Therapies such as corticosteroids and splenectomy are directed at interfering with this process.

Abstract Plasma hemoglobin(Hb) is a measure of circulating red blood cell(RBC) destruction and is considered to be the basic indicator of intravascular hemolysis. We have examined the effects of splenectomy on levels of plasma Hb and circulating RBC-derived vesicles in patients with thalassemia intermedia (TI) and compared the results to patients with sickle cell anemia (SCA). Plasma Hb levels in splenectomized patients with TI were 48.5 ± 3.7 mg/ml (5)(Mn ± SEM)(No.of patients) and vesicle levels were 11.29 ± 1.12 x 10 3 /ul blood (9).

Abstract Abstract 2038 Congenital Dyserythropoietic Anemia type II (CDAII) is an autosomal recessive disorder caused by mutations in the gene SEC23B. SEC23B is a component of the COPII coat complex that transports proteins from the endoplasmic reticulum (ER) to the Golgi apparatus. CDAII is characterized by mild to moderate anemia and >10% bi- or multi- nucleate erythroblasts in the bone marrow. We generated Sec23b deficient mice (Sec23b gt/gt) from ES cells with a genetrap cassette inserted into the last intron of Sec23b. Sec23b gt/gt mice die at birth with destruction of the exocrine panc

Anemia due to premature destruction of RBCs is classified as hemolytic, and may be secondary to acquired or inherited (congenital) abnormalities in RBC membrane, hemoglobin, or metabolism. This article reviews the topic of congenital hemolytic anemias and points out a practical approach to diagnosis and therapy. PATHOPHYSIOLOGY The primary function of RBCs is to transport oxygen from the lungs to the tissues. The normal RBC circulates within the vascular system for about 120 days. Survival to its full life span depends upon effective metabolism of glucose to generate high-energy phosphates suc

Hemoglobin is the natural carrier of oxygen in red blood cells (RBCs). While intracellular hemoglobin provides life-sustaining oxygen transport, extracellular free hemoglobin displays toxicity due to inherent peroxidase activity generating reactive oxygen species that subsequently react with the hemoglobin molecule to produce toxic heme degradation products resulting in free radicals, oxidative stress damage, and lipid peroxidation. We have recently demonstrated that Peptide Inhibitor of Complement C1 (PIC1) inhibits peroxidase activity of the heme-based enzyme myeloperoxidase. To elucidate wh

Abstract Oxidative stress is a prominent contributor to the premature destruction of RBC as well as anemia in thalassemia and sickle cell anemia. The oxidative status within RBC is maintained by the balance between oxidative systems, such as Reactive Oxygen Species (ROS), and antioxidative systems, such as reduced glutathione (GSH). Using flow cytometric methods, we previously showed that RBC obtained from patients with thalassemia (Amer et al. Eur J Haematol70:84,2003; Cytometry60:73,2004) or sickle cell anemia (Amer et al.

Abstract Plasma-derived human IgG (IVIg) have been used for more than 2 decades for the treatment of several autoimmune diseases such as ITP, even if their mechanism of action is still not fully understood. Recently, several studies with IVIg-treated patients have shown that IVIg can modulate the serum level of both pro-inflammatory and anti-inflammatory cytokines. In ITP, it is known that the destruction of autoantibody-coated platelets occurs mainly in the spleen. We thus used a mouse model of ITP to evaluate the modulatory effects of IVIg on the expression of several cytokine genes in the s

Abstract Transfusion protocols have remained unchanged for decades. Accordingly, it is necessary to avoid transfusion reactions by giving patients ABO- and irregular antibody-compatible red blood cells (RBC). Prevention of immunization to the Rh antigen D is also required since anti-D may cause a serious hemolytic disease of fetus and newborn. Prevention of transfusion-induced immunization to other blood group antigens is neither required nor feasible for the general transfused population.

Patients with sickle cell anemia often receive multiple red blood cell (RBC) transfusions during their lifetime. Hyperhemolysis is a life-threatening phenomenon of accelerated hemolysis and worsening anemia that occurs when both transfused RBCs and autologous RBCs are destroyed. The level of hemoglobin post-transfusion is lower than pre-transfusion levels, and patients are usually hemodynamically unstable. Hyperhemolysis must be differentiated from a delayed hemolytic transfusion reaction during which destruction of transfused RBC is the cause of anemia. Hyperhemolysis syndrome can be differen

Thalassemia (thal) is an autosomal recessive, hereditary, chronic hemolytic anemia due to a partial or complete deficiency in the synthesis of α-globin chains (α-thal) or β-globin chains (β-thal) that compose the major adult hemoglobin (α2β2).It is caused by one or more mutations in the corresponding genes. The unpaired globin chains are unstable; they precipitate intracellularly, resulting in hemolysis, premature destruction of red blood cell [RBC] precursors in the bone marrow, and a short life-span of mature RBCs in the circulation. The state of anemia is treated by frequent RBC transfusion

Recent studies suggest that antibody-induced “antigen-modulation” may in part be responsible for this cellular resistance to antibody-mediated removal following the initial phase of RBC clearance. However, the factors that dictate whether cells undergo clearance or antigen modulation immediately following incompatible RBC transfusion remain unkn
