ABSTRACT
A healthy 9-years-old boy was brought to the Emergency Department for widespread abdominal pain associated with bloody diarrhoea and significant tenesmus, in the absence of fever. Blood tests were compatible with an acute gastroenteritis, even though microbiological tests on stools resulted negative. Given the haemorrhagic dysentery, the boy was hospitalized to start empiric antibiotic therapy and intravenous rehydration. Abdominal ultrasound showed a thickening of colonic walls, mimicking an inflammatory intestinal disease at the onset (subsequently denied by gastro-colonoscopy). Seven days after the onset of symptoms, blood tests revealed microangiopathic anaemia with negative Coombs test, associated with thrombocytopenia. Urine dipstick revealed haematuria and proteinuria in nephritic range. No contraction of diuresis or alteration of renal function were observed (being creatinine values always within the normal range). Laboratory tests were consistent with the diagnosis of Haemolytic Uremic Syndrome (Hus) at the onset. Approximately 1% of paediatric patients with bloody diarrhoea can develop Hus. Positivity for Escherichia coli is not always evident in the stools. Thus, the triad of haemolytic anaemia, thrombocytopenia and renal failure could be present in only 60% of Hus at the onset. The finding of haematuria and/or proteinuria on the urine dipstick may be indicative of early kidney damage, allowing for careful monitoring and a rehydration program that can prevent progression of kidney damage and extrarenal complications.
