During RBC transfusion, production of alloantibodies against RBC non-ABO Ags can cause hemolytic transfusion reactions and limit availability of compatible blood products, resulting in anemia-associated morbidity and mortality. Multiple studies have established that certain inflammatory disorders and inflammatory stimuli promote alloimmune responses to RBC Ags. However, the molecular mechanisms underlying these findings are poorly understood. Type I IFNs (IFN-α/β) are induced in inflammatory conditions associated with increased alloimmunization...

Theoni Kanellopoulou
Hemolysis after solid organ transplantation can be caused by both immune and non-immune mediated mechanisms and the evaluation must take into account issues distinctive to the post-transplant period. Autoimmune hemolytic anemia usually occurs within the first year and has been attributed to immunosuppressive treatment, infections or underlying post-transplant lymphoproliferative disorder. Review of the literature revealed 59 cases with autoimmune hemolytic anemia mostly in children after liver transplantation...

Antiphospholipid Syndrome (APS) is an autoimmune disorder with clinical and laboratory features of vascular thrombosis, pregnancy loss, and persistent antiphospholipid antibodies (aPLs). The pathophysiology is thought to involve the activation of endothelial cells, monocytes, platelets, and complement by aPLs. Disease can range from asymptomatic to rapidly fatal catastrophic APS. We present a case of a 34-year-old male referred for pancytopenia and splenomegaly. On examination, he had decreased sensation and 4/5 power in the left upper extremity...

Platelet satellitism is a rare phenomenon observed in blood smears obtained from blood anticoagulated with EDTA with an estimated frequency at 0.008%. It is characterized by platelet rosetting around neutrophils and in rare cases around other blood cells, which may causes pseudothrombocytopenia. Our case involves a 26-year-old female patient with autoimmune hemolytic anemia (AIHA). Blood smear with EDTA as an anticoagulant had platelet satellitism whereas the phenomenon was not observed in tubes with different anticoagulants (citrate, heparin) and capillary blood...

Acquired pure red cell aplasia (PRCA) and autoimmune hemolytic anemia (AIHA) are rare complications of immunosuppression in pediatric solid organ transplant patients. We report a 14-month-old female child who developed Coombs positive hemolytic anemia and reticulocytopenia while on tacrolimus after cardiac transplantation. She was successfully treated with rituximab after failing treatment with corticosteroids and intravenous immunoglobulins. Clinicians should consider PRCA differential diagnosis in a patient presenting with reticulocytopenia and hemolysis...

This review examines the several lines of evidence that support the relationship between myelodysplasia and autoimmunity, i.e. their epidemiologic association, the existence of common immune-mediated physiopathologic mechanisms, and the response to similar immunosuppressive therapies. The same relationship is reviewed here considering idiopathic cytopenia of uncertain significance (ICUS) and idiopathic dysplasia of uncertain significance (IDUS), two recently recognized provisional conditions characterized by isolated/unexplained cytopenia and/or dysplasia in <10% bone marrow cells...

Primary chronic cold agglutinin disease (CAD) is a well-defined clinicopathologic entity in which a bone marrow clonal B-cell lymphoproliferation results in autoimmune hemolytic anemia and cold-induced circulatory symptoms. Rituximab monotherapy or fludarabine-rituximab in combination are documented treatment options. In a prospective, non-randomized multicenter trial, 45 eligible patients received rituximab 375 mg/m(2) day 1 and bendamustine 90 mg/m(2) day 1 and 2 for 4 cycles at 28 days interval. Thirty-two patients (71%) responded; 18 (40%) achieved complete response (CR) and 14 (31%) partial response (PR)...

OBJECTIVE: Any erythrocyte transfusion among humans having type A or B blood groups is impossible due to antibodies causing fatal transfusion complications. A cross-match test is performed to prevent immune transfusion complications before transfusion. Our hypothesis is that the Fragment antibody (Fab) part of antibody (incomplete antibody) may be used to prevent an immune stimulus related to complete antibody. Therefore, we designed a pilot study to evaluate the effectiveness of these incomplete antibodies with using cross-match tests...

Discovery of the Coombs' test was an epoch-making event in the history of managing autoimmune hemolytic anemia (AIHA). The Coombs' test allows immune-related hemolytic anemia to be distinguished from nonimmune acquired hemolytic anemia, but also creates a complicated category; Coombs-negative AIHA. To resolve this problem, several trials have been conducted to detect immunoglobulin (Ig) G molecules on erythrocytes (RBC-IgG) that the Coombs' test cannot detect. In Japan, RBC-IgG can be quantitated using a radioimmunoassay, but this procedure is time-consuming and expensive...

BACKGROUND Chronic lymphocytic leukemia (CLL) usually expresses CD5 antigen. However, 7-20% of patients are CD5 negative. We report here a series of 19 CD5-negative B-CLL cases. MATERIAL AND METHODS We reviewed 19 consecutive CD5-negative B-CLL cases seen in our medical center from 2009 to 2015 and compared them with 105 CD5-positive B-CLL cases. The two groups were compared in terms of clinical parameters, laboratory parameters, and survival characteristics. RESULTS Lymphadenopathy was present in 31.5% of the CD5-negative group and 51...

Autoimmune cytopenias (AICs) are frequently associated with chronic lymphocytic leukemia (CLL). The most common of these AICs is autoimmune hemolytic anemia (AIHA); the second most is immune thrombocytopenia (ITP). Here, we report on a patient with CLL-associated ITP, with thrombocytopenia refractory to corticosteroids and intravenous immunoglobulins, in which continuous oral treatment with Eltrombopag allowed initiation and maintenance of an oral anticoagulation treatment with Acenocoumarol that was indicated because of a severe arrhythmogenic cardiomyopathy...

Autoimmune hematological diseases (AHDs) occur more frequently than other autoimmune complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and are often refractory to treatment. This study was to analyze the incidence and risk factors of AHDs as well as their response to treatment . Four hundred and forty-five adult malignant hematopoietic disorders underwent allo-HSCT were enrolled in this retrospective study, including 124 haploidentical donor (HRD), 140 unrelated donor (MUD) and 181 HLA-matched sibling donor (MSD) transplants...

PURPOSE: The anion channel protein band 3 is the main target of the pathogenic red blood cells (RBC) autoantibodies in New Zealand black (NZB) mice. CD4 T cells from NZB mice with autoimmune hemolytic anemia respond to band 3. Previously, we have shown that IL-10 and peptides containing a dominant T cell epitope from red cell band 3 modulate autoimmune hemolytic anemia in NZB mice. Because of the immunoregulatory role of IL-10 in autoimmune diseases, we aim to identify individual band 3 peptides that induce high IL-10 production and simultaneously suppress CD4 T cell proliferation and to investigate the effect intranasal administration of IL-10 producing band 3 peptides on autoantibody responses of NZB mice...

Thrombotic thrombocytopenic purpura (TTP) is a rare and life-threatening thrombotic microangiopathy characterized by microangiopathic hemolytic anemia, severe thrombocytopenia, and organ ischemia linked to disseminated microvascular platelet rich-thrombi. TTP is specifically related to a severe deficiency in ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13), the specific von Willebrand factor-cleaving protease. ADAMTS13 deficiency is most frequently acquired via ADAMTS13 autoantibodies, but rarely, it is inherited via mutations of the ADAMTS13 gene...
