Presentation
Dialysis may be required for patients presenting with renal failure, and kidney transplant may be considered. [en.wikipedia.org]
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]
Target cells containing abnormally high amounts of unesterified cholesterol and lecithin are present. [ommbid.mhmedical.com]
Patients with FLD and fish-eye disease frequently present with corneal opacity, anemia and renal failure with proteinuria. [degruyter.com]
Entire Body System
- Anemia
Renal function generally stabilized or improved and the anemia improved. [ncbi.nlm.nih.gov]
[…] reversibly transfers an acyl residue from a lecithin to cholesterol, forming a 1-acylglycerophosphocholine (a lysolecithin) and a cholesteryl ester; a deficiency of this enzyme leads to accumulation of unesterified cholesterol in plasma resulting in anemia [medical-dictionary.thefreedictionary.com]
Symptoms of the familial form include diffuse corneal opacities, target cell hemolytic anemia and proteinuria with renal failure. Fish eye disease only causes progressive corneal opacification. [ipfs.io]
This defect results in low HDL-cholesterol level in blood and accumulation of free cholesterol in tissue leading to a triad of CORNEAL OPACITY, hemolytic anemia (ANEMIA, HEMOLYTIC), and PROTEINURIA. [definitions.net]
Eyes
- Corneal Opacity
Signs and symptoms In complete LCAT deficiency patients may present with Anemia, Corneal opacities, Hepatosplenomegaly, renal insufficiency while in partial deficiency (fish eye disease) corneal opacities is the main finding with hepatosplenomegaly. [ipfs.io]
Patients with FLD and fish-eye disease frequently present with corneal opacity, anemia and renal failure with proteinuria. [degruyter.com]
FLD is characterized by corneal opacities, anemia, and proteinuria that may progress to renal failure. [ommbid.mhmedical.com]
[…] in high-density lipoproteins; deficiency of enzyme activity, an inherited disorder, results in accumulation of cholesterol and phosphatidylcholine in plasma and tissues, which causes corneal opacities, anemia, and often proteinuria. [medical-dictionary.thefreedictionary.com]
Two familial forms of LCAT deficiency have been reported: familial LCAT deficiency (FLD, see this term) characterized by corneal opacities, anemia and renal insufficiency, and Fish-eye disease (FED, see this term) characterized by corneal opacities and [orpha.net]
- Corneal Infiltrate
A 20-year-old male of Indian extraction presented with visual impairment principally due to bilateral diffuse punctate corneal infiltration, with peripheral ring opacities. [tandfonline.com]
Urogenital
- Kidney Failure
It is characterized by cloudiness of the clear front surface of the eye ( corneal opacities), a shortage of red blood cells ( hemolytic anemia ), and kidney failure. [rarediseases.info.nih.gov]
[…] to fat deposits in the glomeruli, and premature breakdown of red blood cells leading to anemia Kidney failure and vision deterioration are some of the potential complications of Complete LCAT Deficiency Disorder. [dovemed.com]
The condition is characterized by corneal disorders, anemia, protein in the urine and ultimately, kidney failure. [checkorphan.org]
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]
Patients may present with HDL deficiency, corneal opacification, hemolytic anemia, hypertension, hypertriglyceridemia, and proteinuria. [emedicine.medscape.com]
Treatment
This long-term observation indicates the efficacy of corticosteroids and renin-angiotensin-aldosterone system blockers in the treatment of proteinuria in patients with FLD. [ncbi.nlm.nih.gov]
Management and treatment Kidney function and visual acuity should be monitored in affected patients. Treatment for anemia and renal insufficiency is symptomatic. Hemodialysis or even kidney transplantation may be needed. [orpha.net]
Prognosis
Prognosis Prognosis is variable. End-stage renal disease is the most serious outcome. The documents contained in this web site are presented for information purposes only. [orpha.net]

Prognosis [ edit ] Renal failure is the major cause of morbidity and mortality in complete LCAT deficiency, while in partial deficiency (fish eye disease) major cause of morbidity is visual impairment due to corneal opacity. [en.wikipedia.org]
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]

[…] found that the disease was named so because the cornea of the eye was so opaque or cloudy with dots of cholesterol that it resembled a boiled fish. [5] If an individual only carry one copy of the mutated gene, they typically do not show symptoms. [6] Pathophysiology [en.wikipedia.org]
Fish Eye Disease (FED): Loss of alpha LCAT function with preserved beta function. [9] Pathophysiology Pathogenesis LCAT deficiency is caused by a mutation in the LCAT gene, resulting in disruption of the reverse cholesterol transport. [wikidoc.org]

LCAT gene mutations that cause complete LCAT deficiency either prevent the production of LCAT or impair both alpha-LCAT and beta-LCAT activity, reducing the enzyme's ability to attach cholesterol to lipoproteins. [ghr.nlm.nih.gov]
Lipid abnormalities usually recur after a renal transplant. [31] Prevention There are no screening recommendations for the disease. [wikidoc.org]
