Depression - Can Vitamin D Alleviate Symptoms of Depression Not Cured by Antidepressants as Well as Alleviate Negative Skeletal Effects Caused by Antidepressants?
Abstract
In recent years it has become evident that some types of antidepressants are associated both with an increased risk of falling and decreased bone mineral density. These factors predispose patients for serious fractures such as hip fractures with substantial morbidity and mortality. The specific mechanisms involved in this negative impact on bone and postural control have not been fully elucidated. It is well known that Vitamin D plays an important role for bone health as well as muscle function and thus indirectly postural control. Furthermore, vitamin D deficiency has been observed among depressed patients. To our knowledge no study has investigated the involvement of Vitamin D in relation to the increased risk of fractures associated with antidepressants. Therefore, this project will investigate the underlying mechanisms leading to skeletal impairment and musculoskeletal symptoms in patients receiving different types of antidepressants. Moreover, the effect of vitamin D supplementation will be investigated among patients taking these antidepressants.
150 subjects will participate in this study: 50 of which is diagnosed with depression and receive Citalopram (SSRIs); 50 depressed subjects receiving Mirtazapine(NaSRI); and 50 controls. Through randomisation half of the subjects in each group will receive daily Vitamin D supplementation for a period of one year. Through this period all 150 subjects will be followed through different measurements including bone density, muscle…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 71 participants or records.
