Autoimmune hemolytic anemia (AIHA) is a relatively rare disorder with an incidence of 1-3 per 100,000 [1]. Warm AIHA (WAIHA) is typically due to IgG autoantibodies with optimal reactivity at 37°C and account for the vast majority of AIHA cases (80-90%) [1,2]. Clinical presentation can range from an asymptomatic, compensated hemolytic anemia to acute life-threatening hemolysis. Hemolysis is typi...

marrow examination actually showed relative erythroid hypoplasia. Many patients with homozygous thalassemia have intense erythropoietic marrow activity, with M:E ratios of 1:20. Thus, in this case, a M:E ratio of 1:8 may not truly reflect hyperplasia relative to this child’s baseline condition. Due to the different results reported in the immunohematologic studies, a definite explanation about ...

A 58-year-old man with warm-antibody-mediated autoimmune hemolytic anemia (AIHA) refractory to prednisolone, azathioprine, splenectomy, rituximab and combination chemotherapy, and with unacceptably high transfusion requirement, was treated with alemtuzumab. After a cumulative dose of 883 mg of alemtuzumab, the AIHA remitted completely, with normalization of hemoglobin and transfusion-independen...

INTRODUCTION BAFF (B-cell activating factor of the TNF family), an important regulator of B-cell, has been observed to be over-expressed in a variety of autoimmune diseases. Autoimmune hemolytic anemia (AIHA) is an acquired autoimmune disease occurred when antibodies directed against autologous red blood cells. We assessed serum levels of BAFF in AIHA patients with different serological charact...

Autoimmune hemolytic anemia (AIHA) is most often idiopathic. However, in recent years, AIHA has been noted with increased incidence in patients receiving purine nucleoside analogues for hematologic malignancies; it has also been described as a complication of blood transfusion in patients who have also had alloimmunization. As the technology of hematopoietic stem cell transplantation has become...

OBJECTIVES Intraperitoneal (IP) injection of 3.5 g/kg L-arginine (known to induce acute pancreatitis) in rats will result in much greater increases in serum ornithine versus citrulline concentration (Crit Care Med. 2008;36:2117-2127). These data indicate a major role of arginase in the catabolism of L-arginine. Therefore, we tested the effects of the irreversible arginase inhibitor (+)-S-2-amin...

AIHAs can be subdivided according to underlying disease (Table 1). No underlying disease or agent can be distinguished in primary AIHA, whereas in the secondary cases, an associated condition is well documented such as autoimmune diseases, malignancies, infections or drugs. Malignancies are one of the most common causes. AIHA can be seen at the diagnosis or during the course of cancers such as ...

Autoimmune hemolytic anemia (AIHA) is characterized by shortened red cell survival due to the presence of autoantibodies directed against antigens on the red blood cell membrane. Corticosteroids and rarely intravenous immunoglobulin G are used in the treatment of AIHA. We report a six-month-old boy with severe AIHA who initially responded to high dose methylprednisolone (HDMP) and intravenous i...

Soltani, N., Vyn, R. J., Van Eerd, L. L., Shropshire, C. and Sikkema, P. H. 2009. Effect of reduced herbicide rates on weed control, environmental impact and profitability of corn. Can. J. Plant Sci. 89: 969 975. A study was conducted over a 3-yr period (2003, 2004, and 2005) to evaluate the effect of reduced herbicide rates 20, 40, 60, 80, and 100% of the manufacturer’s recommended rate (MRR) ...

Auto Immune Hemolytic Anemia (AIHA) is a rare entity in children. We report a case of an adolescent girl with AIHA, which was precipitated by chicken pox. Clinical course over 3 years, till remission is described.
