  Hemolytic Anemia
Hemolytic anemia is sometimes caused by a vitamin E deficiency.
When these anemias are present without any accompanying disease or disorder, it is possible that the membrane surface of the RBC is expressing a new protein (antigen) not made elsewhere in the body and therefore, not recognized as part of the normal self.

The goals of treating hemolytic anemia are to reduce or stop the hemolysis of red blood cells, to increase the red blood cell count to normal levels, and to treat the underlying cause.

ABSTRACT: Hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) are syndromes of microangiopathic hemolytic anemia, and thrombocytopenia in which endothelial dysfunction appears to be an important factor in the sequence of events leading to microvascular thrombosis.
Thrombocytopenia and hemolytic anemia are the laboratory hallmarks of thrombotic microangiopathy (Fig.

 Hemolytic Uremic Syndrome - keep kids healthy
Hemolytic uremic syndrome (HUS) is a disorder that usually causes microangiopathic hemolytic anemia (destruction of red blood cells in small and medium sized blood vessels), thrombocytopenia (a low platelet count), and acute renal failure.
Other blood tests will include a creatinine to see how the kidneys are functioning and measurement of electrolytes, which may show a low sodium (hyponatremia), high potassium (hyperkalemia) and an increased level of acid in the blood (acidosis).
Treatments for hemolytic uremic syndrome depend on the severity of anemia and renal failure and may include careful management of how much fluid your child receives, blood transfusions, and dialysis, including peritoneal dialysis if possible.

Hemolytic-uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) are microangiopathic disorders—that is, they are characterized by abnormalities (chiefly blood clots) that occur within the small blood vessels of the body.
Such clotting is associated with hemolytic anemia (low red blood cell count due to cell rupture) and low numbers of platelets (cell-like bodies responsible for blood coagulation).
Hemolytic anemia results from the fragmentation of the red blood cells when they pass through areas of thrombi (masses or clots) or turbulence in the circulation.

Thrombotic thrombocytopenic purpura and hemolytic-uremic syndrome are acute, fulminant disorders characterized by thrombocytopenia and microangiopathic hemolytic anemia.
The diagnosis is suggested by thrombocytopenia and anemia, with fragmented RBCs on the blood smear (helmet cells, triangular-shaped RBCs, distorted-appearing RBCs—these changes describe microangiopathic hemolysis); evidence of hemolysis (falling Hb level, polychromasia, elevated reticulocyte count, elevated serum LDH); and negative direct antiglobulin (Coombs') test.
Otherwise unexplained thrombocytopenia and microangiopathic hemolytic anemia are sufficient evidence for a presumptive diagnosis.
