Acquired hemolytic anemia

Paroxysmal cold hemoglobinuria (PCH), also known as Donath-Landsteiner syndrome, is a disease of humans that is characterized by the sudden presence of hemoglobin in the urine (called hemoglobinuria), typically after exposure to cold temperatures.

Thrombotic microangiopathy, abbreviated TMA, is a pathology that results in thrombosis in capillaries and arterioles, due to an endothelial injury.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, life-threatening disease of the blood characterized by destruction of red blood cells by the complement system, a part of the body's intrinsic immune system.

Autoimmune hemolytic anemia (or autoimmune haemolytic anaemia; AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to insufficient plasma concentration.

Cold agglutinin disease is an autoimmune disease characterized by the presence of high concentrations of circulating antibodies, usually IgM, directed against red blood cells.

Warm Antibody Autoimmune Hemolytic Anemia (WAIHA) is the most common of the autoimmune hemolytic diseases.

Drug-induced autoimmune hemolytic anemia is a form of hemolytic anemia.

Drug-induced nonautoimmune hemolytic anemia is a form of hemolytic anemia.

Acquired hemolytic anemia can be divided into immune and non-immune mediated forms of hemolytic anemia.

Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis fetalis, is an alloimmune condition that develops in a fetus, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta.

Hemolytic-uremic syndrome (or haemolytic-uraemic syndrome), abbreviated HUS, is a disease characterized by hemolytic anemia (anemia caused by destruction of red blood cells), acute kidney failure (uremia), and a low platelet count (thrombocytopenia).

In medicine (hematology) microangiopathic hemolytic anemia (MAHA) is a microangiopathic subgroup of hemolytic anemia (loss of red blood cells through destruction) caused by factors in the small blood vessels.
