Presentation
Presentation A deficiency of LCAT causes accumulation of unesterified cholesterol in certain body tissues. Cholesterol effluxes from cells as free cholesterol and is transported in HDL as esterified cholesterol. [ipfs.io]
Dialysis may be required for patients presenting with renal failure, and kidney transplant may be considered. [en.wikipedia.org]
Patients with FLD and fish-eye disease frequently present with corneal opacity, anemia and renal failure with proteinuria. [degruyter.com]
Multilaminar figures were present, and total lipid extracts were enriched with phospholipid and cholesterol; cholesteryl esters were reduced, and accounted for about 12% of the cholesterol. [ncbi.nlm.nih.gov]

People with complete LCAT deficiency often have kidney disease that begins in adolescence or early adulthood. The kidney problems get worse over time and may eventually lead to kidney failure. [ghr.nlm.nih.gov]
Workup
Laboratory workup showed a mild normocytic, normochromic anemia; and target cells were seen in the peripheral blood smear. [ncbi.nlm.nih.gov]
Serum
- Hypertriglyceridemia
In 2 patients hypertriglyceridemia and hypercholesterolemia were present, the latter because of an increase in unesterified cholesterol. [ncbi.nlm.nih.gov]
Its primary aim was to determine CETP activities in patients with hypertriglyceridemia and to correlate these activities with HDL-cholesterol levels. Hypertriglyceridemia was defined as plasma total triglycerides in the range of 200 to 500 mg/dL. [ahajournals.org]
Patients may present with HDL deficiency, corneal opacification, hemolytic anemia, hypertension, hypertriglyceridemia, and proteinuria. [emedicine.medscape.com]

Patients with classic FLD develop nephrotic syndrome progressing to end-stage renal disease (ESRD), corneal opacities, dyslipidemia and hemolytic anemia. FED is a milder form of the disease associated with corneal opacity and dyslipidemia. [indianjnephrol.org]
The results suggest the role of inflammatory processes as well as dyslipidemia in the pathogenesis of glomerular disorders in LCAT-deficient patients. [ncbi.nlm.nih.gov]

Etiology
Aubie Angel Springer Science & Business Media, ٠٦/١٢/٢٠١٢ - 303 من الصفحات Current interest in lipoprotein deficiency states stems from the growing realization of their importance in the etiology of premature coronary heart disease. [books.google.com]
Etiology LCAT deficiency is caused by deficient or absent catalytic activity of the LCAT enzyme, which catalyzes the formation of cholesterol esters in lipoproteins and is encoded by the LCAT gene (16q22.1). [orpha.net]
Epidemiology
Summary Epidemiology Prevalence of LCAT deficiency is unknown. About 125 cases have been reported to date worldwide. Most cases were reported in Europe, Japan and Canada. [orpha.net]
Abstract Epidemiological as well as biochemical evidence of recent years has established that a low plasma level of high density lipoprotein-cholesterol is a predictor for the risk of coronary artery disease. [pnas.org]
