Abstract Background Individuals with major depressive disorder (MDD) have high suicidal ideation. There is evidence that serum cystatin C (Cys C) may be involved in the pathophysiology of MDD. The present study aimed to investigate Cys C concentration in patients with MDD and clarify its possible association with depressive symptoms and suicidal ideation. Methods An online cross-sectional survey of 159 patients diagnosed with MDD was conducted. Serum Cys C levels were measured using ADVIA 2400 biochemical analyzer. The 24-item Hamilton Depression Scale (HAMD-24) was administered to evaluate the depressive symptoms. Generalized linear regression, logistic regression and restricted cubic spline models were used to examine the association of serum Cys C levels with depressive symptoms and suicidal ideation. Results Serum Cys C levels were higher in MDD patients than in controls (p = 0.001) and were positively associated with scores on HAMD-24 in unadjusted (gender distribution, age, smoking, alcohol consumption, family history of depression and traumatic life events; (p = 0.003) and fully adjusted linear regression model (p = 0.005). The fully adjusted regression coefficient with 95% confidence intervals for serum Cys C levels and HAMD-24 score was 30.339 (9.602 to 51.077). The level of Cys C in the suicidal ideation (SI) group was significantly higher than that in the non-suicide ideation (non-SI) group (p = 0.001). Serum Cys C levels were positively associated with suicidal ideation in each logistic regression model (all p <  0.05). Conclusion Serum Cys C levels were elevated in MDD patients and appeared to be positively correlated with depressive symptoms and suicidal ideation. These findings suggest that the dysfunction of Cys C may be involved in the severity of depression and in the pathophysiological process of MDD. Thus, regulation of serum Cys C could potentially be an effective predictor of the severity of depression and potentially, play a role in reducing the risk of suicide in MDD patients.

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.

Background: Due to the possible effect of omega-3 fatty acids on reducing depressive symptoms, in this study, we investigated these effects in combination with other antidepressants. Methods: The study was a double-blind clinical trial on 100 patients with major depressive disorder who were divided into four groups of 25 each and treated with 50 mg daily sertraline plus placebo, 50 mg daily sertraline plus two grams Omega 3 daily, 75 mg daily venlafaxine plus placebo, and 75 mg daily venlafaxine plus 2 g Omega 3 daily for 6 weeks. Results: The mean Hamilton depression rating score of sertraline and venlafaxine plus omega-3 after treatment were 4.42 and 4.23 respectively versus sertraline and venlafaxine plus placebo 14.4 and 14.2 respectively (P value=0.0001). Conclusion: Omega-3 enhanced the clinical function of sertraline and venlafaxine to reduce the severity of depression. Adding omega-3 to either sertraline or venlafaxine does not have a comparative advantage over each other in terms of the improvement of severity of depressive symptoms.

Abstract Background Misdiagnosis and ineffective treatment are common in major depressive disorder (MDD) in current clinical practice, while the combination of various proteins involved in the pathogenesis of MDD may assist the correct diagnosis. The study aimed to explore whether the combination of serum inflammatory, stress, and neurotrophic factors could be helpful for the diagnosis of MDD, and to investigate the predictors associated with early symptom improvement. Methods Baseline serum levels of C-reactive protein (CRP), interleukin (IL)-6, IL-10, IL-1beta, tumor necrosis factor (TNF)-alpha, interferon (INF)-gamma, cortisol and brain-derived neurotrophic factor (BDNF) were detected in 30 MDD patients and 30 age- and gender-matched healthy controls. 17-item Hamilton Depression Rating Scale (HAMD-17) and Hamilton Anxiety Rating Scale (HAMA) were applied to assess depressive and anxious symptoms both at baseline and 2 weeks after antidepressant treatment. Stepwise multiple linear regression was employed to identify the early efficacy predictiors; while a logistic regression model was built with above proteins and area under receiver operating characteristic (AUC) curve was calculated to evaluate the model’s diagnostic power. Results Multiple linear regression revealed that baseline socres of retardation ( β =-0.432, P =0.012) and psychological anxiety ( β =-0.423, P =0.014) factors were negatively associated with the reduction rate of HAMD-17. A simple and efficient diagnostic model was established by forward stepwise logistic regression and the model achieved an AUC of 0.884, with 86.7% sensitivity and 83.3% specificity. Couclusions The results showed that combining serum BDNF, cortisol and IFN-gamma could aid the diagnosis of MDD, while baseline retardation and psychological anxiety may negatively predict the early symptom improvement.

Abstract Background Major depressive disorder is one of the most common, burdensome, and costly psychiatric disorders worldwide. Antidepressants are frequently used to treat major depressive disorder. It has been shown repeatedly that antidepressants seem to reduce depressive symptoms with a statistically significant effect, but the clinical importance of the effect sizes seems questionable. Both beneficial and harmful effects of antidepressants have not previously been sufficiently assessed. The main objective of this review will be to evaluate the beneficial and harmful effects of antidepressants versus placebo, ‘active placebo’, or no intervention for adults with major depressive disorder. Methods/design A systematic review with meta-analysis will be reported as recommended by Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), bias will be assessed with the Cochrane Risk of Bias tool-version 2 (ROB2), our eight-step procedure will be used to assess if the thresholds for clinical significance are crossed, Trial Sequential Analysis will be conducted to control for random errors, and the certainty of the evidence will be assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. To identify relevant trials, we will search both for published and unpublished trials in major medical databases from their inception to the present. Clinical study reports will be obtained from regulatory authorities and pharmaceutical companies. Two review authors will independently screen the results of the literature searches, extract data, and perform risk of bias assessment. We will include any published or unpublished randomised clinical trial comparing one or more antidepressants with placebo, ‘active placebo’, or no intervention for adults with major depressive disorder. The following active agents will be included: agomelatine, amineptine, amitriptyline, bupropion, butriptyline, cianopramine, citalopram, clomipramine, dapoxetine, demexiptiline, desipramine, desvenlafaxine, dibenzepin, dosulepin, dothiepin, doxepin, duloxetine, escitalopram, fluoxetine, fluvoxamine, imipramine, iprindole, levomilnacipran, lofepramine, maprotiline, melitracen, metapramine, milnacipran, mirtazapine, nefazodone, nortriptyline, noxiptiline, opipramol, paroxetine, protriptyline, quinupramine, reboxetine, sertraline, trazodone, tianeptine, trimipramine, venlafaxine, vilazodone, and vortioxetine. Primary outcomes will be depressive symptoms, serious adverse events, and quality of life. Secondary outcomes will be suicide or suicide attempt, suicidal ideation, and non-serious adverse events. Discussion As antidepressants are commonly used to treat major depressive disorder in adults, a systematic review evaluating their beneficial and harmful effects is urgently needed. This review will inform best practice in treatment and clinical research of this highly prevalent and burdensome disorder. Systematic review registration PROSPERO CRD42020220279

Abstract Aims To examine the factors that are associated with changes in depression in people with type 2 diabetes living in 12 different countries. Methods People with type 2 diabetes treated in out-patient settings aged 18–65 years underwent a psychiatric assessment to diagnose major depressive disorder (MDD) at baseline and follow-up. At both time points, participants completed the Patient Health Questionnaire (PHQ-9), the WHO five-item Well-being scale (WHO-5) and the Problem Areas in Diabetes (PAID) scale which measures diabetes-related distress. A composite stress score (CSS) (the occurrence of stressful life events and their reported degree of ‘upset’) between baseline and follow-up was calculated. Demographic data and medical record information were collected. Separate regression analyses were conducted with MDD and PHQ-9 scores as the dependent variables. Results In total, there were 7.4% (120) incident cases of MDD with 81.5% (1317) continuing to remain free of a diagnosis of MDD. Univariate analyses demonstrated that those with MDD were more likely to be female, less likely to be physically active, more likely to have diabetes complications at baseline and have higher CSS. Mean scores for the WHO-5, PAID and PHQ-9 were poorer in those with incident MDD compared with those who had never had a diagnosis of MDD. Regression analyses demonstrated that higher PHQ-9, lower WHO-5 scores and greater CSS were significant predictors of incident MDD. Significant predictors of PHQ-9 were baseline PHQ-9 score, WHO-5, PAID and CSS. Conclusion This study demonstrates the importance of psychosocial factors in addition to physiological variables in the development of depressive symptoms and incident MDD in people with type 2 diabetes. Stressful life events, depressive symptoms and diabetes-related distress all play a significant role which has implications for practice. A more holistic approach to care, which recognises the interplay of these psychosocial factors, may help to mitigate their impact on diabetes self-management as well as MDD, thus early screening and treatment for symptoms is recommended.
