Major Depressive Disorder
Conditions
Brief summary
Cilostazol is a PDE 3 inhibitor, which showed as decrease in HAM-D scores in post-stroke depression through inhibition of neurodegeneration in the primary lesion and secondary extrafocal sites and through promotion of neurogenesis. These beneficial effects on post-stroke depression may be involved in activation of CREB/BDNF signaling.The aim of the current study is to evaluate the potential adjunct antidepressant effect of cilostazol in adult patients with MDD. Furthermore, we will assess the relationship between HAM-D score and BDNF as well as their role as a therapeutic targets of MDD.
Detailed description
Cilostazol produces various powerful pleiotropic effects via restoration of intracellular second messenger cyclic adenosine monophosphate (cAMP). Treatment with cilostazol against cerebral ischemic injury ameliorates negative effects of cerebral hypoperfusion through the PDE3- cAMP signaling cascade with subsequent activation of inducible transcription factor cAMP response element-binding protein (CREB), suggesting the importance of the CREB signaling pathway. Activation of CREB promotes the gene expression of neuroprotective molecules that activate subsequent anti-apoptotic pathways with the gene expression of brain-derived neurotrophic factor (BDNF). BDNF also regulates neurogenesis, proliferation, and survival of neural stem or progenitor cells, as well as neuronal survival. In addition, CREB and BDNF signaling play an important role in the pathophysiology of major depressive disorder . Psychopharmacotherapy with antidepressants or mood stabilizers provides an effective treatment for depression after stroke, but alternative therapy by activation of CREB and BDNF signaling may exert beneficial effects on various aspects of negative mood. Drugs that activate CREB and BDNF signaling may provide a potential therapeutic approach for treatment of poststroke depression via neural cell survival and proliferation of neural progenitor cells. The aim of the current study is to evaluate the potential adjunct antidepressant effect of cilostazol in adult patients with MDD. Furthermore, we will assess the relationship between HAM-D score and BDNF as well as their role as a therapeutic targets of MDD.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effect on Hamilton Depression rating scale score (HAM-D score) | 6 weekS | The principal measure of the outcome was the 17-items HAM-D. Scoring is based on the 17-item scale and scores of 0-7 are considered as being normal, 8-13 suggest mild depression, 14-17 moderate depression and scores over 17 are indicative of severe depression. Remission is defined as HAM-D total score ≤ 7 (primary outcome). Treatment response is defined as ≥ 50% drop in the HAM-D total score. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Effect on biological markers | 6 week | Serum level of brain derived neurotrophic factor (BDNF), cAMP response element-binding protein (CREB), SEROTONIN, tumor necrosis factor alpha (TNF-α), Interleukin-6 (IL-6), and Nuclear factor kappa were measured at the baseline and after the treatment to evaluate the biological effects of the used medications. |
