EMILFORK S., Marcos  y  HANNIG K., Sonia. Colitis hemorrágica por Escherichia coli enterohemorrágica O157 H:7. : Comentario en relación a dos casos clínicos . Rev. chil. pediatr. [online]. 1999, vol.70, n.3, pp.221-228. ISSN 0370-4106.

Haemorrhagic colitis caused by Escherichia coli H7-O157. A review and 2 clinical cases E. coli H7: O157 is an emerging infection in Chile. Two serious cases in our unit permit a review of little known aspects of this disease. It differs from that in developed countries where the average age is 15 years, in Chile it affects small children, an with an average age of 1.5 years. This suggests a domestic transmission from an adult who has immunity. The colitis can be severe requiring colectomy, although there are no clear cut indications. It is not proven whether antibiotics increase the incidence of hemolytic uremic syndrome (HUS) but is suggested that their early use should be avoided. Although the diagnostic method is simple, not all laboratories routinely screen for the organism. Treatment should include careful observation, seeking complications e.g. HUS and an adequate management of contacts. Prevention is based on adequate hygiene of cooking utensils, contact with uncooked meats especially if minced. Doctors should seek the aetiology of a haemorrhagic colitis, and Health Authorities promote information about prevention, and commence obligatory notification of the disease.

Palabras clave : Escherichia coli H7: O157; haemorrhagic colitis; hemolytic uremic syndrome.
