Amniotic fluid Interleukin-8 as a marker for intraamniotic infection

Summary We measured the amniotic fluid Interleukin-8 (AF IL-8) levels of 80 women to see whether or not AF IL-8 levels were of value in the diagnosis of intraamniotic infection. Of twelve patients developing conventional signs of infection, 9 had an AF IL-8 concentration above 10.000 pg/ml serum. In two patients, whose baby had a serious neonatal infection, AF IL-8 concentration also exceeded 10.000 pg/ml. Only one out of 66 apparently uninfected patients had an AF IL-8 level above 10.000 pg/ml. We therefore suggest that measuring the AF IL-8 levels is of value in cases of suspected intraamniotic infection.
