Objective: The American Food and Drug Administration have warned about a possible association between statins and the development of new-onset diabetes. Lebanese studies lack sufficient data about this correlation. This study was conducted to evaluate the clinical implication of statins on blood glucose levels among diabetic Lebanese hospitalized patients.
Methods: A four-month retrospective observational study was conducted from February till May 2017. It included 131 type II diabetic patients stabilized on statins for a minimum of one year. In addition to statin type, strength, and duration, fasting blood glucose (FBG), glycosylated hemoglobin (Hba1c), body mass index (BMI), and lipid profiles were recorded.
Results: The mean baseline FBG levels before the initiation of statins and post-statin intake were 115.25 mg/dL and 175.81 mg/dL for atorvastatin 10mg, 110.63 mg/dL and 183.16 mg/dL for atorvastatin 20mg, 119.25 mg/dL and 189.11mg/dl for atorvastatin 40mg, 123.21mg/dL and 202.05mg/dL for rosuvastatin 10mg, 114.53 mg/dL and 169.50 mg/dL for rosuvastatin 20mg, and 118.56 mg/dL and 174.64mg/dL for simvastatin 20mg. The association between statins at different doses and mean FBG levels was statistically significant (p<0.05). The mean baseline glycosylated hemoglobin before statin prescription was 5.63% and significantly increased to 7.5% three months after statin intake (p-value of 0.03).
Conclusion: In view of the evidence, it is difficult to refute that an association exists between statin use and elevated blood glucose levels. Patients on statins should carefully monitor their glucose levels to assess the risk and benefit of statin use.
