Abstract
The increase in plasma triglyceride level in pregnancy is modest, but in those who have deficiencies in lipoprotein lipase or apolipoprotein C-II (i.e., familial hyperlipidemia), the increase in very LDL concentration cannot be controlled and results in severe hypertriglyceridemia. This case is related to severe primary hypertriglyceridemia (types V) detected on the 25th week of gestation and treated with regular therapeutic plasma exchange and later on with alternate plasmapheresis with donated plasma. No complications were observed. A healthy male baby was delivered on the 39th week of pregnancy. After giving birth, the maternal triglyceride levels showed a remarkable reduction.
