Een pseudo-epidemie van kraamvrouwenkoorts

- Within a four-week period, five patients were admitted to the maternity ward of the Utrecht Children's Hospital diagnosed with puerperal sepsis due to group-A streptococcal infection. The clinical presentation was different for each patient. All patients recovered upon adequate antibiotic treatment. One of the children died, possibly due to sepsis and hypotension of his mother. As group-A streptococci can be extremely contagious and an epidemic was suspected, measures for additional hygiene were taken. Furthermore, all personnel at the maternity ward and the obstetric centre were tested. T-serotyping, M-genotyping, exotoxin A- and C-gene amplification and pulsed field gel electrophoresis were used to characterize the cultured group-A streptococci. Cross-contamination was not found. Therefore, this increase in puerperal sepsis was attributed to polyclonal expansion rather than an epidemic. All mothers of newly born children who present with fever and lower abdominal pain should be suspected of group-A streptococcal infection. Evaluation and treatment in hospital is indicated due to a sometimes fulminant course. When group-A streptococci are cultured again in a new pregnancy, eradication therapy during pregnancy or prophylactic treatment during birth should be considered to prevent recurrent infection.
