Objective: To study the anti-inflammatory activity of fluoxetine and escitalopram in newly diagnosed patients of depression and also to evaluate the association between depression and inflammation. Materials and Methods: Ninety-eight newly diagnosed patients of depression were recruited as cases. From these, 48 had started treatment with fluoxetine (20 mg/day) and 50 had started treatment with escitalopram (20 mg/day). After 2 months of treatment of these patients, Hamilton rating scale for depression (HRSD scale), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cell (WBC) count were measured and compared to their respective baseline values before starting treatment. One hundred healthy volunteers were recruited as controls and their baseline of CRP, ESR and WBC count were measured and compared with their respective baseline values of cases. Severity of depression was measured by HRSD scale and anti-inflammatory activity was measured by reduction CRP, ESR and WBC count. Results: On baseline comparison between cases and controls, there were significant increases in the levels of CRP (P = 0.014), ESR (P = 0.023) and WBC count (P = 0.020) in cases. In fluoxetine (20 mg/day) treatment group, there was a significant reduction in the levels of CRP (P = 0.046), ESR (P = 0.043) and WBC count (P = 0.021) after 2 months of treatment but no significant reduction in HRSD scale (P = 0.190). Similarly, in escitalopram treatment group, there was a significant reduction in CRP (P = 0.041), ESR (P = 0.030) and WBC count (P = 0.017) after 2 months of treatment but no significant reduction in HRSD scale (P = 0.169). Conclusion: In newly diagnosed patients of depression, inflammatory markers such as CRP, ESR and WBC count were significantly raised and Selective serotonin reuptake inhibitors SSRIs such as fluoxetine and escitalopram reduced them independent of their antidepressant effect. So, SSRIs have some anti-inflammatory activity independent of their antidepressant action.
