A patient with warm autoimmune hemolytic anemia (AIHA) due to predominance of immunoglobulin A (IgA) with an Rh specificity, considered to be the first case in Korea, is described. A 13-year-old male patient with severe hemolytic anemia showed a weak reactivity (1+) in the direct antiglobulin test (DAT) by using anti-IgG antiglobulin reagent. This finding, however, could not fully explain the p...

Cold agglutinin disease (CAD) is an autoimmune hemolytic anemia (AIHA) generally caused by IgM autoantibodies which exhibit maximal reactivity at 4°C. CAD can be idiopathic or secondary to some diseases and/or conditions. Only a minority of cases of secondary AIHA in non-Hodgkin's lymphoma (NHL) are associated with cold antibodies. Diffuse large B cell lymphoma (DLBCL) is the most common subtyp...

Autoimmune hemolytic anemia (AIHA) has been described in patients with lymphoid neoplasm with an etiologic relationship between the emergence of autoantibodies and lymphocyte dysfunction. Autoimmune disorders are less to develop in patients with other neoplasm like chronic myeloid leukemia, myelodysplastic syndrome or acute myeloid leukemia. Few reports have been documented the development of i...

In autoimmune hemolytic anemia (AIHA), circulating red blood cells (RBCs) opsonized with autoantibody are recognized by macrophage Fcgamma and complement receptors. This triggers phagocytosis and elimination of RBCs from the circulation by splenic macrophages. We recently found that CD47 on unopsonized RBCs binds macrophage signal regulatory protein alpha (SIRPalpha), generating a negative sign...

BACKGROUND Ataxia telangiectasia (AT) is one of the combined immunodeficiency syndromes with immunologic, neurologic, endocrinologic, hepatic and cutaneous abnormalities. Regarding the fact that autoimmune disorders; such as autoimmune hemolytic anemia (AIHA), are not generally expected in the course of AT, we present a patient with an unusual presentation of these two conditions. CASE PRESEN...

Selective splenic artery embolization (SSAE) is a nonsurgical intervention characterized by the transcatheter occlusion of the splenic artery and/or its branch vessels using metallic coils or other embolic devices. It has been applied for the management of splenic trauma, hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia and splenic hemangioma. We hereby describe a c...

The lupus-prone New Zealand Black (NZB) strain uniquely develops a genetically imposed severe spontaneous autoimmune hemolytic anemia (AIHA) that is very similar to the corresponding human disease. Previous studies have mapped anti-erythrocyte Ab (AEA)-promoting NZB loci to several chromosomal locations, including chromosome 4; however, none of these have been analyzed with interval congenics. ...

Direct Antiglobulin Test A DAT may be ordered by a physician who suspects that the patient is experiencing immune-mediated hemolysis (i.e., an antibody is causing the destruction of the patient’s RBCs). If the sample yields a positive DAT with polyspecific antihuman globulin (AHG) reagent, the result may be due to the presence of IgG and/or complement (C3) attached to the patient’s cells. This ...

PCH is a rare autoimmune hemolytic anemia (AIHA) but is one of the most common causes of AIAH in children. For the diagnosis, it is important to perform the appropriate methods of serological investigation and show the typical biphasic reaction. This is a case report of a child who presented with features of haemolysis and was diagnosed with PCH of this way.

Autoimmune hemolytic anemia is rarely associated with ulcerative colitis, and counts only for 0.2-0.7% of adult patient.Coombs positive autoimmune which account 1.82% in patient colitis without any evidence(1). Here we report a case sever Coombs (AIHA) response to Infliximab.
