Diarrhoea in children: aetiology and clinical aspects.
To determine the aetiology of diarrhoea in children younger than 5 years hospitalised for acute enteritis and to evidence the chief clinical aspects in correlation with different aetiological agents, a total of 402 children with acute diarrhoea were examined between February 2003 and December 2006 in the Paediatric Department of Sondrio Hospital. Faecal samples were collected and processed by routine microbiological and biochemical tests. For all patients the clinical signs and symptoms on admission were evidenced. Most of the patients (310/402, 77.1%) were infected by rotavirus, while of the remaining 82 (22.9%) 40 were infected by salmonella species. In 42 patients, no bacterial agent was evidenced by microbiological tests. Clinical signs of mild dehydration were observed in 13 children during the hospital stay (all infected by rotavirus), while no case of metabolic acidosis, hypoglycaemia or hypovolaemic shock was documented. Elevated serum levels of uric acid were evidenced in 13/302 (4.3%) of patients with rotavirus infection, while only 1/82 (1.2%) rotavirus-negative children presented a minimal increase in serum uric acid level. Our retrospective study confirms the epidemiological and clinical importance of rotavirus as the main aetiological agent in hospitalised children younger than 5 years affected by acute diarrhoea. There also emerged a possible correlation between rotavirus infection and hyperuricaemia, probably connected with dehydration.
