Introduction: Familial hypercholesterolemia (FH) is an autosomal codominant lipid metabolism disorder. It results in lifelong elevation of plasmatic low-density lipoprotein cholesterol (LDL-C) levels, followed by premature atherosclerosis. In women, pregnancy and lactation represent an additional risk due to association of physiological changes, pre-existing dyslipidemia, and limited therapeutic possibilities and experiences. Methods of extracorporeal LDL-apheresis represent a suitable therapeutic approach.
Case series: We present our experience in case reports of six HoFH women and their 13 pregnancies (nine successful, three abortions, and one interruption). One patient experienced a lethal complication of her pregnancy. Of the nine successful pregnancies, two cases were treated by LDL-apheresis.
Conclusion: Pregnancy in HoFH women represents substantial risk; however, patients without signs of decompensated cardiovascular disease can have a good prognosis. LDL-apheresis plays an important role in the management of pregnancy in HoFH.
