title: [Peripheral blood neutrophils reactive oxygen intermediates (ROI) production in early pregnancy complicated by diabetes mellitus type I].
abstract: The components of maternal innate immune system are activated in pregnancy. Increased number of circulating neutrophils and monocytes, reactive oxygen intermediate production (ROI), increased expression of the adhesion molecules can be observed. The activation status and neutrophils response to stimulators in pregnant diabetic women's comprise, to some extend, both situations pregnancy and diabetes, combined effect of both seems to be very intriguing.
  
  
  OBJECTIVE
  Evaluation production of ROI on peripheral blood neutrophils in early pregnancy of diabetic mothers.
  
  
  METHODS
  12 pregnant diabetic women demonstrating good glycemic control and without major complications before pregnancy were studied at 8-12 weeks of first gestation, 11 healthy pregnant women match for weeks of gestation, age and parity; 11 healthy non-diabetic women; 13 diabetic, non-pregnant women, were also studied.
  
  
  METHODS
  ROI production was evaluated with chemiluminescence method using standard stimuli fMLP, PMA, OZ and also after 15 min. priming with TNF-alpha. We used MLX Microtiter Plate Luminometr DYNEX, USA. with computer program Revelation 97. For statistic analysis Fisher, Kolmogorow-Smirnow and Wilcoxon tests were used (p < 0.05).
  
  
  RESULTS
  1. Peripheral blood neutrophils of healthy pregnant, diabetic and pregnant diabetic women independently from the stimuli used showed an increase in ROI production 2. Peripheral blood neutrophils change their activity, evaluate by ROI production during pregnancy, diabetes and pregnancy complicated by diabetes. 3. Peripheral blood neutrophils of pregnant diabetes women do not show expected impairment of their function.
  
  
  CONCLUSIONS
  Diabetes type 1 with good glycemic control and pregnancy, change the production of ROI by peripheral blood neutrophils but these events do not sum up in diabetic pregnancies.
