Abstract

Case report: The patient was a 50-year old male who was found to have a high cholesterol level during a routine health check up at work 5 years before and was examined at Keio University Hospital. Lipoprotein electrophoresis on agarose gel revealed type III hyperlipidemia, and a screening test yielded the following values (mg/dl): total cholesterol, 420; TG, 138; and HDL-cholesterol, 105. Turbidimetric immunoassay showed that the apolipoprotein E (apoE) level was below the limit of detection. Since he was 25 years old, the patient had sometimes noticed xanthomas on his knees and eyelids, and for that reason we made a diagnosis of apoE deficiency associated with type III hyperlipidemia. We tried using SDS-polyacrylamide gel electrophoresis, Western blot, and the protein chip method to detect apoE in this case, but the level was below the limit of detection by the first two methods, and it was so low that it was detected near the sensitivity limit of the protein chip method. Diet therapy, statin therapy, and fibrate therapy have been continued, and the latest data are: total cholesterol, 373; TG, 95; and HDL-cholesterol, 83. No manifestations associated with arteriosclerotic disease other than mild xanthomas have been observed.
