- Infection with E. coli O157:H7 is diagnosed by detecting
the bacterium in the stool. Most laboratories that culture stool do
not test for E. coli O157:H7, so it is important to request
that the stool specimen be tested on sorbitol-MacConkey (SMAC) agar
for this organism. All persons who suddenly have diarrhea with blood
should get their stool tested for E. coli O157:H7.
- Most persons recover without antibiotics or other specific treatment
in 5-10 days. There is no evidence that antibiotics improve the course
of disease, and it is thought that treatment with some antibiotics may
precipitate kidney complications. Antidiarrheal agents, such as loperamide
(Imodium), should also be avoided.
- Hemolytic uremic syndrome is a life-threatening condition usually
treated in an intensive care unit.
- HUS develops in about 5% of reported E. coli O157:H7 cases, most frequently in young children or the elderly.
- Blood transfusions and kidney dialysis are often required. With intensive care, the death rate for hemolytic uremic syndrome is 3%-5%.
