Depression and Anxiety Disorders in COVID-19 Survivors: Role of Inflammatory Predictors.

Introduction: Infection-triggered perturbation of the immune system, which was observed after previous coronavirus outbreaks, could induce psychiatric sequelae. The spreading of the Coronavirus-19 (COVID-19) pandemic could be associated with psychiatric implications. In this study, we aimed to evaluate the association between inflammatory biomarkers and the levels of depression and anxiety in patients who recovered from COVID-19. Methods: We screened 109 COVID-19 survivor adults for psychiatric symptoms on the 15th day of follow-up after discharge from the hospital. The patients were split into two groups, the ones with depression and anxiety, and the ones without depression or anxiety, after the psychiatric interview. Self-rating Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were applied to assess the levels in patients with depression and anxiety. We collected and recorded the sociodemographic information, clinical data, and baseline inflammatory markers. Results: Higher baseline neutrophil/lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) were found in patients with depression and anxiety. Higher levels of depression and anxiety were found in younger and female patients. Besides, a significant correlation was found between BAI and ferritin levels in patients with anxiety, while no association was found between BAI and other inflammatory biomarkers. Moreover, no significant relationship was found between BDI scores and inflammatory biomarkers in patients with depression. Conclusion: COVID-19 primarily affects the respiratory and cardiovascular systems. Nonetheless, psychiatric involvement is not uncommon and can lead to severe problems if not detected and managed at an early stage. It is recommended that clinicians should be vigilant in terms of psychiatric involvement in COVID-19 patients presenting with high inflammatory parameters.
