In pregnant female with FH, apheresisis the preferred treatment because standard therapeutic agents such as statins are contraindicated during pregnancy. LDL adsorption therapy is commonly used; however, after 27 weeks of gestation, it is often switched to dual filtration plasma exchange (DFPP) due to the significant drop in blood pressure caused by bradykinin production. However, DFPP has limited ability to adapt to the increase in circulating plasma volume associated with pregnancy. Here we discuss the case ofa 32-year-old female with homozygous FH who underwent different apheresis strategies during her pregnancies. In her first pregnancy, she continued LDL adsorption therapy using DFPP but ultimately delivered a small-for-gestational-age infant via cesarean section. For her second pregnancy, double-filtration plasmapheresis thermo mode, DF-thermo, was introduced to mitigate the limitations of DFPP and LDL adsorption therapies, such as hypotension during apheresis and albumin loss. By minimizing these complications, DF-thermo allowed for a successful delivery without compromising fetal growth.  \nKey words: Familial hypercholesterolemia, Double-filtration plasmapheresis thermo-mode, Pregnancy  \n\n| Introduction:\u003Cbr>Familial hypercholesterolemia (FH) is a genetic disease characterized by elevated low-density lipoprotein (LDL) cholesterol concentration and early onset of atherosclerotic cardiovascular disease. Treatment of FH includes a low-fat diet and smoking cessation guidance and management of comorbidities such as diabetes and hypertension, use of statins and other medications and LDL apheresis 1) . Although most therapeutic agents such as statins are contraindicated in pregnant females with FH, with a | few exceptions, continued apheresis during pregnancy is desirable to ensure appropriate lipid management for increased cardiovascular stress due to increased blood coagulation capacity, platelet function, and blood viscosity during pregnancy 2) . Here we discuss a case in which double-filtration plasma exchange therapy (DF-thermo) was successfully applied to a pregnant patient with FH, allowing for effective LDL cholesterol management within the target range while minimizing hypotension and albumin loss. |\n| --- | --- |\n\nAddress for correspondence: Haruhito A.
