Summary
A case of homozygous hypercholesterolaemia in a young girl is presented. Treatment with diet, statins, and ezetimibe significantly reduced high cholesterol levels.
Area of Science:
- Biochemistry
- Genetics
- Cardiology
Background:
- Homozygous hypercholesterolaemia is a rare genetic disorder characterized by extremely high levels of low-density lipoprotein (LDL) cholesterol.
- Early diagnosis and intervention are crucial to prevent premature cardiovascular disease.
Observation:
- A young girl of Indian origin presented with unusual hand nodules and markedly elevated total cholesterol (> 25 mmol/L).
- Genetic analysis revealed a mild P664L mutation, indicating a potential genetic predisposition to hypercholesterolaemia.
Findings:
- Diet and statin therapy led to a 38% reduction in total cholesterol.
- Adding ezetimibe resulted in an additional 26% decrease in total cholesterol and a 37% reduction in LDL cholesterol.
Implications:
- This case highlights the effectiveness of a multi-modal treatment approach, including ezetimibe, for managing severe hypercholesterolaemia.
- Alternative therapies like LDL-apheresis and liver transplantation are also discussed as viable options for refractory cases.
