A case of chylomicronemia syndrome is reported in a 72-year-old male with distinctive features of chronic pancreatic damage, severe hypertriglyceridemia, polidistrectual atherosclerosis and premature cognitive impairment. Although the patient had a positive history for recurrent episodes of pancreatitis the characteristic lesions of the hyperchylomicronemia syndrome, such as eruptive xanthomas and lipemia retinalis, were not present and splenomegaly could not be documented due to a previous post-traumatic splenectomy. Based on clinical phenotype, an apolipoprotein C-II deficiency was excluded by a fresh plasma infusion test, in which clarification of the patient plasma was not obtained. The absence of changes in the lipoprotein electrophoretic plasma after heparin infusion can be secondary to a lipoprotein lipase deficiency, a rare genetic disorder with an incidence of one per million. In relation to the resistance to diet and drugs, plasma exchange therapy was performed. After 3 years of this treatment there was no significant progression of atherosclerosis.

Rodents have at least five carboxylesterase 1 (Ces1) genes, whereas there is only one CES1 gene in humans, raising the question as to whether human CES1 and mouse Ces1 genes share the same functions. In this study, we investigate the role of human CES1 in the development of steatohepatitis or dyslipidemia in C57BL/6 mice. Hepatocyte-specific expression of human CES1 prevented Western diet or alcohol-induced steatohepatitis and hyperlipidemia. Mechanistically, human CES1 induced lipolysis and fatty acid oxidation, leading to a reduction in hepatic triglyceride and free fatty acid levels. Human CES1 also reduced hepatic-free cholesterol levels and induced low-density lipoprotein receptor. In addition, human CES1 induced hepatic lipoprotein lipase and apolipoprotein C-II expression. Conclusion: Hepatocyte-specific overexpression of human CES1 attenuates diet-induced steatohepatitis and hyperlipidemia.
