Introduction. Warm antibody hemolytic anemia (warm AIHA) represents the most frequently encountered form of autoimmune hemolytic anemia (AIHA).This condition is characterized by the production of autoantibodies that exhibit optimal reactivity at or above normal human body temperature, within the range of 36.5 to 37.5°C.

2025年2月4日 · Autoimmune hemolytic anemia (AIHA) is caused by autoantibodies that react with self red blood cells (RBCs) and cause them to be destroyed. Warm AIHA, due to antibodies that are active at body temperature, is the most common type of AIHA. This topic reviews the evaluation and management of warm AIHA in adults. Separate topic reviews discuss:

2021年3月11日 · Warm autoimmune hemolytic anemia (wAIHA) is the most prevalent form of autoimmune hemolytic anemia (AIHA), accounting for 60% to 70% of all cases. It is usually due to an immunoglobulin G (IgG) autoantibody that may activate complement (C) if present at high titer or if IgG1 and IgG3 subclasses are prevalent.

2022年12月9日 · Warm autoimmune hemolytic anemia (wAIHA) is characterized by evidence of red blood cell (RBC) hemolysis and a direct antiglobulin test positive for IgG and sometimes complement. While varying with the extent of the compensatory increase in RBC production, symptoms of anemia predominate, as does jaundice, the latter often exacerbated by ...

Warm antibody autoimmune hemolytic anemia (WAIHA) is the most common form of autoimmune haemolytic anemia. [1] About half of the cases are of unknown cause, with the other half attributable to a predisposing condition or medications being taken.

2024年7月30日 · Warm autoimmune hemolytic anemia (wAIHA) is an autoimmune disorder characterized by the premature destruction of healthy red blood cells (hemolysis). Autoimmune diseases occur when someone’s own immune system attacks healthy tissue.

Warm autoimmune hemolytic anemia. The most common type of AIHA, warm autoimmune hemolytic anemia, involves IgG antibodies, which bind red blood cells at normal body temperature. Generally, symptoms occur gradually over the course of several weeks. In some cases, however, they can develop within days. Cold autoimmune hemolytic anemia

Warm antibody hemolytic anemia (wAIHA) is the most common form of autoimmune hemolytic anemia (AIHA). The “warm” in its name refers to the autoantibodies generated by the body, which are active only at body temperatures of 37 degrees Celsius or higher and attach to and prematurely destroy red blood cells (RBCs).

Autoimmune hemolytic anemia (AIHA) is a rare and heterogeneous disease that affects 1 to 3/100 000 patients per year. AIHA caused by warm autoantibodies (w-AIHA), ie, antibodies that react with their antigens on the red blood cell optimally at 37°C, is the most common type, comprising ∼70% to 80% of all adult cases and ∼50% of pediatric cases.

2016年12月2日 · Autoimmune hemolytic anemia (AIHA) is a rare and heterogeneous disease that affects 1 to 3/100 000 patients per year. AIHA caused by warm autoantibodies (w-AIHA), ie, antibodies that react with their antigens on the red blood cell optimally at 37°C, is the most common type, comprising ∼70% to 80% of …
