Clinical Trial Summary

The study aims to investigate the effects of breastfeeding on lipid profile and cardiovascular risk markers in women with familial hypercholesterolemia (FH) compared to women without FH. Women with and without FH who are pregnant or planning pregnancy will be recruited, and will be invited to repeated study visits from the end of pregnancy and through the first year after delivery. Blood samples and data on anthropometry, health, pregnancy, lifestyle and diet will be collected. Statin transfer into breast milk will also be measured in breast milk samples collected when the women end breastfeeding the child and start statin treatment.


Clinical Trial Description

Patients with familial hypercholesterolemia (FH) have elevated plasma levels of LDL-cholesterol from first years of life. Cholesterol burden through life defines risk of cardiovascular disease. In women with FH, cholesterol levels increase during pregnancy both due to physiological changes as well as discontinuation of cholesterol lowering medication during planning of pregnancy, during the pregnancy and during breastfeeding. Few studies on the effects of breastfeeding on lipid profile in women with FH exists. There is also limited data on whether and to what extent the cholesterol lowering statins transfer to breast milk. The study aims to investigate the effects of breastfeeding on lipid profile and cardiovascular risk markers in women with familial hypercholesterolemia (FH) compared to women without FH. Women with and without FH who are pregnant or planning pregnancy will be recruited, and will be invited to repeated study visits from the end of pregnancy and through the first year after delivery. Blood samples and data on anthropometry, health, pregnancy, lifestyle and diet will be collected. Statin transfer into breast milk will also be measured in breast milk samples collected when the FH women end breastfeeding the child and start statin treatment. ;
