General Discussion

Hemolytic-Uremic Syndrome (HUS) is a very rare disorder that primarily affects young children between the ages of one and 10 years, particularly those under the age of four years. In many cases, the onset of HUS is preceded by a flu-like illness (gastroenteritis) characterized by vomiting, abdominal pain, fever, and diarrhea, which, in some cases, may be bloody. Symptoms of Hemolytic-Uremic Syndrome usually become apparent three to 10 days after the development of gastroenteritis and may include sudden paleness (pallor), irritability, weakness, lack of energy (lethargy), and/or excretion of abnormally diminished amounts of urine (oliguria). The disease typically progresses to include inability of the kidneys to process waste products from the blood and excrete them into the urine (acute renal failure); a decrease in circulating red blood cells (microangiopathic hemolytic anemia); a decrease in circulating blood platelets, which assist in blood clotting functions (thrombocytopenia); and the abnormal accumulation of platelets within certain blood vessels (microthrombi), reducing the blood flow to several organs (e.g., kidneys, pancreas, brain) potentially leading to multiple organ dysfunction or failure. In some cases, neurological problems may be present at the onset of Hemolytic-Uremic Syndrome or may occur at any time during the disorder's progression. Neurological symptoms may include dizziness, seizures (partial or generalized), disorientation or confusion, and/or loss of consciousness (coma). The onset of Hemolytic-Uremic Syndrome is most frequently associated with infection by a particular strain (O157:H7) of Escherichia coli (E. coli) bacterium. Occasionally, adults may be affected by Hemolytic-Uremic Syndrome.
