[Simvastatin (40 mg/day) in patients with hereditary hypercholesterolemia: effect on high density lipoprotein
Insights
Simvastatin therapy significantly increased high-density lipoprotein (HDL) cholesterol in patients with low baseline levels. This study demonstrates simvastatin
Area of Science:
- Cardiology
- Pharmacology
- Biochemistry
Background:
- Hereditary type II hypercholesterolemia is characterized by elevated cholesterol levels.
- Low high-density lipoprotein (HDL) cholesterol is a risk factor for cardiovascular disease.
- Simvastatin is a statin medication used to lower cholesterol.
Purpose of the Study:
- To investigate the effect of simvastatin on high-density lipoprotein (HDL) cholesterol levels.
- To assess the impact of simvastatin on lipid profiles in patients with hereditary hypercholesterolemia.
Main Methods:
- A 3-month study involving 15 patients with hereditary type II hypercholesterolemia.
- Simvastatin was administered at 40 mg/day after a washout period.
- Blood lipids, liver enzymes, and creatine kinase were monitored at 1 and 3 months.
Main Results:
- Simvastatin was generally well-tolerated.
- In patients with initially low HDL cholesterol, levels increased by 20% after 1 month.
- Total and LDL cholesterol significantly decreased in patients with both low and normal baseline HDL levels.
Conclusions:
- Simvastatin (40 mg/day) effectively lowers LDL cholesterol in hereditary hypercholesterolemia.
- Simvastatin significantly increases HDL cholesterol in patients with initially low HDL levels.
- The study confirms simvastatin's role in managing dyslipidemia.
Aim:
To study effect of simvastatin of the level of high density lipoprotein (HDL) cholesterol (CH).
Material And Methods:
Simvastatin (40 mg/day) was given for 3 months to 15 patients (3 men, 12 women, mean age 56-/+10.3 years) with hereditary type II hypercholesterolemia after washout from lipid lowering therapy. Initial level of HDL CH was below and above 1.0 mmol/l in 7 and 8 patients, respectively. Blood lipids, activity of liver enzymes and creatine kinase were determined after 1 and 3 months of therapy with simvastatin. Safety and tolerability of simvastatin were also studied.
Results:
Simvastatin was well tolerated. In 1 patient the drug was stopped because of pain in the liver and nausea. In patients with initially low HDL CH levels of total and low density lipoprotein (LDL) CH significantly decreased by 29.6 and 36.8%, respectively, after 3 months, while level of HDL CH increased by 20% after 1 month of therapy. In patients with initially normal HDL CH levels of total and LDL CH significantly decreased by 31.1 and 32.6%, respectively, while those of triglycerides and HDL CH did not change.
Conclusion:
In patients with hereditary hypercholesterolemia 40 mg/day of simvastatin besides pronounced lowering of LDL CH level caused significant increase of HDL CH (up to 20% in 1 month) in patients with initially low level of this parameter.
