WebThere are two main types of autoimmune hemolytic anemia, called warm antibody and cold antibody. In the cold type, the autoantibodies are most active at temperatures below 30 … WebWarm autoantibodies (WAA) are targeted against “self” antigens on the red cell surface, and react best at body temperatures (contrast to cold autoantibodies ). Warm autoantibodies typically react against all RBCs (they are “ panagglutinins “), though they may occasionally show some increased strength when certain Rh antigens are present).

WebCold autoimmune hemolytic anemia. Affecting 10% to 20% of cases, cold autoimmune hemolytic anemia involves IgM autoantibodies. These bind red blood cells when your blood is at cooler temperatures compared to your body’s core temperature. There’s a wide variation in the temperature threshold at which a cold autoantibody will bind to red ... WebPertechnetate radionuclide imaging of the thyroid showed diffusely increased radiotracer uptake consistent with Graves' disease and a cold nodule in the right lobe. Needle aspiration from the nodule yielded evidence of Hashimoto's thyroiditis. The patient also tested strongly positive for antithyroid peroxidase antibodies. nazca earthworks
