Association of interleukin-6 with suicidal ideation in veterans: A longitudinal perspective

Introduction: Studies showing associations between inflammation in suicide are typically cross-sectional. Present study investigated how cytokine levels track with suicidal ideation and severity longitudinally. Methods: Veterans with a diagnosis of major depressive disorder (MDD) with or without suicide attempt history (MDD/SA n = 38, MDD/NS n = 41) and non-psychiatric non-attempter controls (HC n = 33) were recruited, MDD/SA and HC groups were followed longitudinally at […]

Increased C-reactive protein concentration and suicidal behavior in people with psychiatric disorders: A systematic review and meta-analysis

Objective: Suicide is a leading cause of death worldwide. Identifying factors associated with suicidality (suicidal ideation [SI]/suicidal behavior) could increase our understanding of the pathophysiological underpinnings of suicide and improve its prevention. Methods: We conducted a systematic review (PubMed/PsycInfo/Cochrane databases, up to September 2020) and random-effect meta-analysis including observational studies comparing peripheral C-reactive protein (CRP) levels in […]

Role of inflammation in suicide: From mechanisms to treatment

Suicidal behavior is complex and manifests because of a confluence of diverse factors. One such factor involves dysregulation of the immune system, which has been linked to the pathophysiology of suicidal behavior. This review will provide a brief description of suicidality and discuss the contribution of upstream and downstream factors in the etiology of suicidal […]

The role of inflammation in suicidal behaviour

Objective Over the past decade, clinical data have accumulated showing that inflammation might contribute to the pathophysiology of suicide. To evaluate the associations and to identify the support for pathways linking inflammatory processes with suicidal behaviour, a comprehensive review of the literature was undertaken. Method The search terms ‘cytokine’, ‘risk factors’, ‘kynurenine’, ‘asthma’, ‘allergy’, ‘autoimmunity’, […]

Can suicide behavior and seasonality of suicide be predicted from inflammatory parameters in adolescents?

According to the 2017 data of World Health organization approximately 800 million individuals commit suicide annually. After understanding that psychiatric  disorders start the inflammation process by suppressing the brain, a number of studies using neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and  monocyte/lymphocyte ratio have been conducted. Platelet/lymphocyte ratio, neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio and other hemogram parameters may […]
