title: [Risk factors for eclampsia: a case-control study].
abstract: OBJECTIVE
  Our purpose was to characterize the risk factors of eclampsia in women with preeclampsia.
  
  
  METHODS
  A case-control study was conducted at Monastir hospital to investigate risk factors for eclampsia between 1st January 1995 and 30th June 2000. Cases were matched to preeclamptic controls on a 2:1 ratio. Univariate analysis was used to determine which of the independent variables were significantly different between the groups. Those with significant differences were then entered into multiple logistic regression analysis to determine the characteristics that were independently related to eclampsia.
  
  
  RESULTS
  A total of 41 cases of eclampsia were ascertained from deliveries. The ratio of eclampsia cases to number of deliveries over the study period was 1.87 per 1000. The first seizures occurred at home in 59% of the cases. Univariate analysis revealed statistical significance for the following variables associated with eclampsia: systolic hypertension > or =160 mmHg and diastolic > or =110 mmHg, headache, visual symptoms, vivid deep tendon reflexes, proteinuria >3+ or >3 g d(-1), uric acid concentration > or =350 micromol l(-1), serum creatinine concentration >100 micromol l(-1) and aminotransferase aspartate >30 IU l(-1). A history of abortion appears to be the protective factor against eclampsia. However, with subsequent multivariate analysis, only vivid deep tendon reflexes and elevated uric acid concentration remained significant.
  
  
  CONCLUSIONS
  These data indicate a need for improved prenatal care and medical attention focused on prodroms of eclampsia as well as the detection of preeclampsia to reduce the incidence of eclampsia.
