Brief Summary:
A tonic active epithelial Na+ channel (ENaC) in pre-eclampsia (PE) escaped normal hormonal control may offer an attractive explanatory model for the pathophysiology of established PE. The channel is activated by plasmin. Microalbuminuria predicts the development of pre-eclampsia in pregnant patients with pregestational diabetes type 1. The investigators hypothesize that urine-plasmin excreted in the kidneys, when proteinuria occurs, could be the cause. The investigators want to test the correlation between measurable plasmin/plasminogen in the urine early in pregnancy and the development of preeclampsia in pregnant patients with type 1 diabetes.

Actual Study Completion Date : October 2015

pregestational type 1 diabetes
It is an observational study. No intervention is made.

Primary Outcome Measures :
  1. preeclampsia [ Time Frame: 3 years ]
    The development of preeclampsia, defined by hypertension ( > 140/90 mmHg) and proteinuria ( >0,3 g/24 hour).

Secondary Outcome Measures :
  1. preterm delivery [ Time Frame: 3 years ]
    post-partum registration of preterm delivery

  2. light for gestational age [ Time Frame: 3 years ]
    post-partum registration of "light for gestational age"

Biospecimen Retention:   Samples With DNA
whole blood serum plasma urine

Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
pregnant women with pregestational type 1 diabtes are included when they show up for their first outpatient pregnancy visit around the 9th weeks gestation.

Inclusion Criteria:

  • singleton gravida,
  • over 18 years,
  • Pregestational type 1 diabetes. Gestation week 8-14.

Exclusion Criteria:

  1. Possible comorbidity like systemic lupus erythematosus (SLE), hypertension and rheumatoid arthritis.
  2. Organic or systematic diseases with clinical relevance ( ex. Malignity)

However it has to be mentioned that quite some patients have thyroid diseases with no impact on the kidneys nor hypertension. It is therefore possible to include these patients.

Thyroid diseases are NOT a reason for exclusion.
