Scientific title | Effectiveness of dalteparin therapy as intervention in recurrent pregnancy loss |
Study acronym | ETHIGII |
Study objectives | This study aims at analysing if the rate of pregnancy losses before the 24th week of gestation can be reduced by dalteparin (low molecular heparin) treatment. |
Ethics approval(s) | Ethics Commission of the Friedrich Schiller University Jena, Faculty of Medicine (Ethikkommission der Friedrich-Schiller-Universität Jena, Medizinischen Fakultät), approval received on October, 26th, 2006 (reference number: 1837-08/06). |
Health condition(s) or problem(s) studied | Pregnant women with a history of recurrent pregnancy loss |
Intervention | Patients will be randomised between: 1. Dalteparin 5000 IE daily and multivitamin two tablets daily 2. Multivitamin two tablets daily Treatment duration: up to the 24th week of gestation |
Intervention type | Supplement |
Primary outcome measure | Ongoing intact pregnancy at 24 weeks of gestation |
Secondary outcome measures | 1. Live birth 2. Late pregnancy complication, defined as at least one of the following: a. preterm delivery (before 37 weeks of gestation) b. placenta insufficiency c. intrauterine growth restriction less than fifth percentile d. preeclampsia e. abruptio placentae 3. Foetus with structural anomalies 4. Symptomatic thromboembolic events 5. Side effects of dalteparin therapy (e.g. thrombocytopenia, osteoporosis, haemorrhage) |
