A rare case of COVID-19 pneumonia with severe hyperlipoproteinemia

A 55-year-old woman was admitted to our hospital for coronavirus disease 2019 (COVID-19) pneumonia. Her symptoms improved upon treatment with steroids, remdesivir and heparin. After discharge, she consumed excessive alcohol because of taste disorder due to COVID-19; she also had chylomicronemia with a triglyceride (TG) level of 8750 mg/dl. Chylomicrons and very-low-density lipoprotein were detected by electrophoresis, and she was diagnosed with severe hyperlipoproteinemia, suspected to be Type V hyperlipoproteinemia. She did not have any symptoms of pancreatitis, and her TG levels decreased with fat intake restriction and sobriety. This is a rare case of COVID-19 with hyperlipoproteinemia, and the causes of hyperlipoproteinemia might be associated with COVID-19 complications, steroids and/or lifestyle changes during the pandemic; therefore, changes in TGs should be observed carefully after the resolution of COVID-19.
