Hemolytic uremic syndrome: an emerging health risk.
نویسنده
چکیده
Hemolytic uremic syndrome is caused primarily by Shiga toxin-producing Escherichia coli O157:H7. The most common cause of acute renal failure in children, hemolytic uremic syndrome also can occur in adults. Characteristic features of the syndrome are microangiopathic anemia, thrombotic thrombocytopenia, and renal failure. Although the presentation of this syndrome is diverse, the classic prodromal illness is bloody diarrhea following ingestion of hamburger meat contaminated with E. coli O157:H7, the most common mode of infection in the United States. Children with hemolytic uremic syndrome generally present with gastroenteritis complaints (e.g., abdominal pain or tenderness, nausea or vomiting, fever, anemia); affected adults may be asymptomatic. Complications from hemolytic uremic syndrome can include intussusception, chronic renal failure, and seizures in severe cases. Because an incubation period of approximately one week occurs between the start of diarrhea and the onset of hemolytic uremic syndrome, physicians should maintain a high index of suspicion; early laboratory testing is important to diagnose and manage this syndrome. Obtaining a complete blood count and stool culture and performing Shiga toxin testing are the first of a series of tests that may help diagnose hemolytic uremic syndrome.

Background: Atypical hemolytic uremic syndrome (aHUS) is a life-threatening and scarce disorder characterized by acute renal failure and disease, non-immune microangiopathic hemolytic anemia and thrombocytopenia, leading to end-stage renal failure or death, and consequently maybe accompanying by extra renal manifestations.

متن کاملHemolytic Uremic Syndrome Risk and Escherichia coli O157:H7
We reviewed medical records of 238 hospitalized patients with Escherichia coli O157:H7 diarrhea to identify risk factors for progression to diarrhea-associated hemolytic uremic syndrome (HUS). Data indicated that young age, long duration of diarrhea, elevated leukocyte count, and proteinuria were associated with HUS.

Hemolytic Uremic Syndrome Incidence in New York1
A comparison of New York's traditional communicable disease surveillance system for diarrhea-associated hemolytic uremic syndrome with hospital discharge data showed a sensitivity of 65%. Escherichia coli O157:H7 was found in 63% of samples cultured from hemolytic uremic syndrome patients, and samples were more likely to be positive when collected early in illness.
