Statin use in type 1 diabetes mellitus patients significantly decreased insulin sensitivity and worsened metabolic control. Cardiovascular benefits of statins may outweigh these risks, but potential metabolic effects require consideration.
Area of Science:
- Cardiovascular Medicine
- Endocrinology
- Pharmacology
Background:
- Statins are widely used for cardiovascular event prevention.
- Emerging evidence suggests statins may negatively impact insulin sensitivity and secretion.
- This effect is noted in healthy individuals and those with type 2 diabetes.
Purpose of the Study:
- To investigate the impact of statin therapy on insulin sensitivity in patients with type 1 diabetes mellitus (T1DM).
Main Methods:
- Prospective observational study over 56 months with 832 T1DM patients (aged 25-61).
- Statin initiation (atorvastatin or simvastatin, 10-40 mg) based on dyslipidemia and clinical need (N=345).
- Insulin sensitivity assessed via estimated glucose disposal rate; statin users compared to statin-free group.
Main Results:
- Statin users (N=345) showed a greater decrease in insulin sensitivity (19.27% vs 12.82%, P < .001) and metabolic control deterioration.
- Statin use was associated with a 36.7% increased risk of decreased insulin sensitivity (HR 1.36).
- Adjustments made for age, gender, disease duration, smoking, and antihypertensive therapy.
Conclusions:
- Statin therapy was shown to deteriorate insulin sensitivity in T1DM patients.
- While cardiovascular benefits may outweigh metabolic risks, potential worsening of metabolic control warrants consideration.
- Further research is needed for a clear molecular explanation of these adverse effects.
