Secondary Recurrent Miscarriage
Conditions
Keywords
recurrent miscarriage, immunology, intravenous immunoglobulin, miscarriage
Brief summary
The investigators want to test whether infusions of intravenous immunoglobulin - a blood product known to modify immune responses - in early pregnancy will increase the chance of a subsequent live birth in women with three or more miscarriages after a birth and a total of at least four miscarriages. This will be done in a trial where 82 patients will be randomly allocated to infusions with intravenous immunoglobulin or placebo during pregnancy.
Interventions
Intravenous infusions, 25-35 g each time, 4th to 15th gestational week
Repeated infusions of Human Albumin 5%, 250-350 ml between 4th and 15th gestational week
