Insights
Homozygous Familial Hypercholesterolemia (FHO) patients exhibit severe cardiovascular disease and anatomic abnormalities due to high LDL-cholesterol. Lipid peroxidation, indicated by malondialdehyde levels, is also present in these patients.
Area of Science:
- Genetics
- Cardiovascular Medicine
- Biochemistry
Background:
- Familial Hypercholesterolemia (FHO) is a severe autosomal genetic disorder.
- It results from mutations in the LDL receptor gene, leading to high plasma LDL-cholesterol and B-Apolipoprotein.
- This causes significant anatomic and pathological abnormalities.
Purpose of the Study:
- To investigate the clinical and pathological findings in patients with Homozygous Familial Hypercholesterolemia (FHO).
- To assess lipid peroxidation markers in FHO patients.
Main Methods:
- Study included 8 patients diagnosed with FHO.
- Clinical data on anatomic/pathologic abnormalities were collected.
- Malondialdehyde (MDA) levels were measured in plasma and atherosclerotic plaques from one autoptic case.
Main Results:
- Patients presented with severe cardiovascular disease and cutaneous xanthomatosis.
- Elevated LDL-cholesterol and B-Apolipoprotein levels were confirmed.
- Malondialdehyde (MDA) levels, an indicator of lipid peroxidation, were measured.
Conclusions:
- Homozygous Familial Hypercholesterolemia (FHO) leads to severe health complications.
- Lipid peroxidation may play a role in the pathophysiology of FHO.
- Early diagnosis and management are crucial for FHO patients.
Abstract:
The authors have studied 8 patients with Homozygous Familial Hypercholesterolemia (FHO) an autosomal genetic dominant disease due to mutation of the gene encoding a cell surface receptor for LDL. Anatomic and pathologic abnormalities caused by LDL-cholesterol and B-Apolipoprotein high plasma levels were found. We also measured malondialdehyde levels in plasma and atherosclerotic plaques of the only autoptic case observed. MDA-levels are an index of lipid peroxidation. Cutaneous xanthomatosis lesions and severe cardiovascular disease were also present.
