Diarrhoea in Swedish infants. Aetiology and clinical appearance

Abstract

Ninety-five children with gastroenteritis admitted at the Department of Paediatrics, Malmö General Hospital, Malmö, Sweden, starting November 1978 through October 1979 were studied. Patients were examined clinically and the course of their disease was followed. Stool specimens from all patients were analysed by routine bacteriology and rotavirus identification was done by immune-electroos-mophoresis. Fifty-eight per cent of patients had rotavirus. Campylobacter was found in 6%, enteropathogenic E. coli in 2%, Yersinia enterocolitica in 2% and Salmonella in 1% of patients. Stool specimens from 53 healthy children matched for sex and age served as controls for bacterial pathogens. All were negative. Forty per cent of patients presented with a clinical dehydration, but only 11%-half of them with bacterial enteropathogens-needed i.v. therapy and 4% required antibiotic treatment. Median time for hospitalization was three days. Vomiting, fever, watery diarrhoea and initial clinical dehydration were more commonly associated with rota virus infection. Macroscopic blood in stools was restricted to patients with bacterial aetiology.
