Management of a young HoFH patient during pregnancy using Lipoprotein Apheresis (whole blood): A novel experience.

Abstract

The pregnancy of a patient with homozygous familial hypercholesterolemia (HoFH) represents a challenge in the clinical setting due to the high cardiovascular risk of the mother and maternal-fetal morbidity. The lipid lowering drugs are generally contraindicated and lipoprotein apheresis (LA) is the only accepted treatment in HoFH pregnant woman. Liposorber D, an LA technique on whole blood, has good efficacy, safety, and short operative time. We present a 31-year-old Caucasian pregnant woman with HoFH clinical phenotype on lipid-lowering treatment with Lomitapide and Evolocumab, discontinued during pregnancy. In multidisciplinary team it was decided to submit the patient to LA throughout the pregnancy. Liposorber D sessions (a whole blood technique) were performed on a strict weekly frequency. The treatment resulted in massive decrease of total cholesterol (TC) and LDL cholesterol (LDL-c), with no significant side effects. The pregnancy presented a normal course and a cesarean section was performed on clinical indications unrelated to the use of LA. She gave birth to a healthy male child at 37 weeks of gestation. LA is considered the only effective, safe and accepted therapy during HoFH pregnancy. This is the first reported case of successful pregnancy treated with Liposorber D, a whole blood LA technique. LA with dextran sulfate has been an effective and safe choice for the mother and fetus. Furthermore it was reasonably well tolerated from the beginning of pregnancy management to its conclusion.
