Prevalence, clinical correlates and IQ of suicidal ideation in drug naïve Chinese Han patients with major depressive disorder

Background: Suicide has a strong association with mental disorder and contributes to the excess mortality of the mentally ill. Suicidal ideation is prevalent and appears to be a precondition for suicide attempts among psychiatric patients with Major Depressive disorder. Though ideas and attempts may overlap there are studies that show the two are separate clinical entities with unique psycho-socio demographic profile. Aim: To study correlates in patients with suicidal ideation and those with suicide attempts in a cohort of major depressive disorder patients. Methodology: Study was conducted at the Inpatient psychiatry unit at a private medical college in Coimbatore, Tamil Nadu. It was a Cross sectional study design. Patients consecutively admitted with major depressive disorder (DSM IV TR) were recruited. Severity of suicidal ideations and attempts were rated on validated scales and the socio demographic and clinical correlates were analyzed. Results: Clinical correlates like severity of depression, severity of suicidal ideation and history of past suicidal attempt were positively correlated with severity of suicidal ideation as well as severity of current suicidal attempts in the cohort of depressive disorder patients. Conclusion: Assessment of current episode severity of both suicidal ideation as well as suicidal attempt is important in identifying high risk patients with major depressive disorder.

Investigating the neurobiological mechanism of suicidal ideation (SI) in major depressive disorder (MDD) may be beneficial to prevent the suicidal behavior. Mounting evidence showed that habenula contributed to the etiology of MDD. The habenula is a key brain region that links the forebrain to midbrain, crucial for the processing of reward and aversion. The aim of the present study was to identify whether first-episode, drug-naive MDD patients with SI displayed altered habenula neural circuitry. Forty-three and 38 drug-naïve patients with first-episode MDD with or without SI (SI+/– group) and 35 healthy control subjects (HC) underwent resting-state functional magnetic resonance imaging. The whole-brain habenula static (sFC) and dynamic functional connectivity (dFC) were calculated to identify regions showing significant difference among these three groups followed by region of interest to region of interest post hoc analysis. For sFC, compared with SI– and HC groups, SI+ group showed decreased sFC from habenula to the precuneus and the inferior frontal gyrus. Patients with MDD displayed increased sFC from habenula to the putamen but decreased sFC to the precentral gyrus. For dFC, SI+ group showed increased dFC from habenula to the superior temporal gyrus, the precuneus, but decreased dFC to the lingual gyrus, the postcentral gyrus, when comparing with SI– and HC groups. Patients with MDD, regardless of SI, displayed decreased dFC from the habenula to the angular gyrus. These findings provide evidence that SI in first-episode, drug-naïve patients with MDD may be related to an abnormality in habenula neural circuitry, which may provide the theoretical basis of novel treatments.

Abstract Objectives Mental disorders have a large impact on death by suicide. Hence, this study aims to determine the prevalence of suicidal behaviors among major depressive disorder (MDD) patients and the associated factors. Materials and Methods This cross-sectional analytical study was conducted among individuals aged 18 to 65 years, diagnosed with MDD in the Psychiatry Outpatient Department of a Tertiary Care Center, Puducherry during March to October 2019. Severity of depression was assessed using Hamilton Depression Rating Scale and Columbia-Suicide Severity Rating Scale was used to find the suicidal behaviors. Results For 166 participants in the study, mean (standard deviation) age was 40 (11) years and majority were females (76%). More than one-third (37%) had severe or very severe depression, and the prevalence of suicidal ideation, plan, and attempts were 83, 24, and 35%, respectively. After adjusting the covariates, the severity of depression and unemployment were significantly associated with suicidal attempts (adjusted prevalence ratios [aPR] = 11.4 and 1.9), and very severe depression was associated with suicidal ideation (aPR = 1.6). Among 140 individuals with suicidal ideation, 45 (32%) had an ideation frequency of 2 to 3 times/week, 69 (50%) had ideation for 1 hour, 36 (26%) could control ideation with little difficulty, and 12% had suicidal ideation mostly to end or stop their pain. Conclusion Suicidal ideation and attempts were significantly high in MDD patients, and the severity of depression was significantly associated with it. Early identification of high-risk suicidal behavior and implementation of effective preventive interventions are necessary to reduce death by suicide in these groups.
