CHAMORRO NOCEDA, Luis Alberto. Hemolytic Uremic Syndrome Caused by Shiga Toxin type 2 Produced by Enterohemorrhagic Escherichia coli O157:H7: First Case Described in Paraguay. Pediatr. (Asunción) [online]. 2009, vol.36, n.2, pp. 127-132. ISSN 1683-9803.
Hemolytic uremic syndrome is a clinical syndrome characterized by a diagnostic triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. We present the case of an infant over two years of age who presented with an episode of bloody flux. On day 5 the patient was hospitalized with the symptom triad of hemolytic anemia, acute renal failure, and thrombocytopenia, which are characteristic of hemolytic uremic syndrome with diarrhea (D+ HUS) requiring transfusion of red blood cell concentrate due to severe hemolytic anemia, while the acute renal failure and thrombocytopenia were of mild intensity. The childs condition improved and he was discharged after 48 hours in good condition. The fecal culture was positive for Escherichia coli O157:H7 Stx2, a known causative agent of the syndrome, making this the first such case reported in Paraguay.
