NeoThyr - the Role of Mitochondria-dysfunction in Newborns of Mothers With Autoimmune Thyroid Disease
Previously, studies have shown that children of women with thyroid autoantibodies experience more birth complications and poorer health in their first days. Studies have also shown later signs of cognitive developmental challenges (risk of attention deficit/hyperactivity problems) among children of mothers with autoimmune thyroid disease. In Denmark there is no formalized screening or treatment of subclinical thyroid disease - with or without Thyroid Peroxidase Antibodies (TPO-antibodies) - among pregnant women.
The hypothesis of this study is that the offspring of women with subclinical thyroid disease have a mitochondria-dysfunction which leads to more complications during birth, poorer health and well-being in the early childhood. The investigators will test this by recruiting mothers by a blood sample in the third trimester of pregnancy, screen the cord blood at birth and later on test the children with Bayley test two times in the early childhood.

Time Perspective: Prospective
|Official Title:||NeoThyr - the Role of Mitochondria-dysfunction in Newborns of Mothers With Autoimmune Thyroid Disease|
- Mitochondrial function [ Time Frame: Delivery ]Maternal and cord blood. Analyses will be run by flow cytometry and qPCR
- Perinatal complications [ Time Frame: At birth ]Number of children in each group with abnormal apgar score, cord pH, need of CPAP, resuscitation, low blood sugar, cramps, death
- Well-being [ Time Frame: Age 0-15 months ]Number of children in each group that have been admitted to the hospital due to icterus, difficulties eating, weight loss or metabolic disease
- Weight (kg) [ Time Frame: Age 0-15 months ]Differences between the two groups
- Length (cm) [ Time Frame: Age 0-15 months ]Differences between the two groups
- Head circumference (cm) [ Time Frame: Age 0-15 months ]Differences between the two groups
- Motor development [ Time Frame: Age 0-15 months ]Numbers of children in each group with abnormal motor development will be evaluated by parental registration of motor development milestones
- Motor development [ Time Frame: Age 6 and15 months ]Differences between the two groups, evaluated by Bayley test
- Cognitive development [ Time Frame: Age 6 and 15 months ]Differences between the two groups, evaluated by Bayley test
- Language [ Time Frame: Age 6 and 15 months ]Differences between the two groups, evaluated by Bayley test
- Birth complications [ Time Frame: Birth ]Number of birth complications in the two groups in terms of hemorrhage >500 ml, abruptio placentae and pre-eclampsia
- Social/emotional behavior [ Time Frame: Age 12 months ]Differences between the two groups, evaluated by ASQ:SE
