Cholesteryl Ester Storage Disease (CESD) is an autosomal recessive lysosomal storage disorder
(LSD) caused by mutations in the lysosomal acid lipase gene (LIPA) that markedly reduce
lysosomal acid lipase (LAL) activity, leading to the accumulation of lipids, predominately
cholesteryl esters and triglycerides, in various tissues and cell types. In the liver,
accumulation of lipids leads to diffuse microvesicular steatosis, which progresses to
fibrosis and ultimately, to micronodular cirrhosis. Patients typically present with
hepatomegaly, liver dysfunction, hepatic failure and type II hyperlipidemia. Although
hepatosteatosis is a typical finding, the liver biopsy diagnosis may be misclassified as
non-alcoholic fatty liver disease, non-alcoholic steatohepatitis or cryptogenic liver
disease. Biopsy and radiological findings are not considered diagnostic, but help to
suspicion of CESD. The definitive diagnosis is based on deficient LAL activity and/or LIPA
gene mutations.
CESD is pan-ethnic, however, the disease incidence is unknown. The estimated incidence of the
disease indicates that CESD should be largely underdiagnosed especially in European patients.
Elevation of serum transaminases, and hepatomegaly are early indications of liver impairment.
Therefore, CESD should be considered as a differential diagnosis in liver disease of unknown
origin.
To data, there is no study which evaluated the frequency of CESD in children with unexplained
transaminase elevation and/or organomegaly and/or chronic liver disease. The aim of this
prospective, multicenter and cross-sectional study is to investigate frequency of CESD in
children with unexplained transaminase elevation and/or and/or chronic liver disease and to
identify demographic and clinical features of CESD.
