Plasma exchange for dramatic gestational hyperlipidemic pancreatitis

We describe the response to plasma exchange in a woman with extreme gestational hyperlipidemia and severe pancreatitis. Her serum triglyceride reached an astounding level of 21,300 mg/dl - among the highest concentrations ever recorded. Two consecutive plasma exchanges led to a remarkable reduction in triglyceride levels of 73% and 82%, respectively. Plasma viscosity decreased by 50% after the first plasma exchange. This was associated with an equally dramatic and unexpectedly rapid resolution of severe pancreatitis. Plasma exchange can rapidly and safely resolve extreme hyperlipidemia and be associated with prompt resolution of pancreatitis in women with severe gestational hyperlipidemic pancreatitis.
