In a randomized, double-blind clinical trial, adjuvant atorvastatin improved symptoms of depression and blood lipid values in patients suffering from severe major depressive disorder

The administration of statins seems to be a promising new avenue in the treatment of patients suffering from major depressive disorder (MDD), though patients suffering from severe MDD remain unstudied in this respect. The aim of the present study was therefore to investigate, in a randomized double-blind clinical trial, the influence of adjuvant atorvastatin on symptoms of depression in patients with MDD.; A total of 60 patients suffering from MDD (mean age: 32.25 years; 53% males) received a standard medication of 40 mg/d citalopram. Next, patients were randomly assigned either to the atorvastatin group (20 mg/d) or to the placebo group. Blood lipid values were assessed at baseline and on completion of the study 12 weeks later. Experts rated depressive symptoms via Hamilton Depression Rating Scales (HDRS) at baseline and 3, 6 and 12 weeks later.; HDRS scores decreased over time; the significant Time by Group interaction showed that symptoms of depression decreased more in the atorvastatin than in the placebo group. Compared to the placebo group, in the atorvastatin group cholesterol, triglyceride, and Low Density Lipids (LDL) significantly decreased, and High Density Lipids (HDL) significantly increased over time. HDRS scores and blood lipid values were generally not associated.; The pattern of results suggests that adjuvant atorvastatin favorably influences symptoms of depression among patients with severe MDD. Given that after 12 weeks of monotherapy and adjuvant atorvastatin patients were still moderately to severely depressed, more powerful treatment algorithms such as augmentation and change of medication are highly recommended.
