Studies attempting to clarify the relationship between major depressive disorder (MDD) and the immune system have been increasing in recent years. It was reported that increased production of the main proinflammatory cytokines, such as interleukin-1, interleukin-6, and tumor necrosis factor-alpha, and that of acute phase reactants may play a role in the etiopathogenesis of depression. Stress and depression were reported to increase leukocyte and neutrophil counts and to decrease lymphocyte count. Biological determinants affecting the diagnosis, therapy, and prognosis of depression are quite limited. Therefore, new etiological models are needed to explain the pathophysiology of depression. In recent years, neutrophil–lymphocyte ratio (NLR) was determined to be a good indicator of inflammatory status. There is no study in the literature investigating NLR in MDD. This study aims to examine the role of inflammation in the etiology of depression based on the NLR in MDD patients who are undergoing no pharmacological therapy. A total of 41 patients diagnosed with MDD, who received no antidepressant therapy within the past 1 month, were included in the study, which took place between January and March 2015. The control group consisted of 47 healthy subjects with no psychiatric disorders. A sociodemographic information form and a Beck Depression Scale were administered, and the blood was taken for biochemical analysis. Significant differences were identified in the NLR, neutrophil count, lymphocyte percentage, and leukocyte values of the patient group when compared with the control group (P<0.05). Our study is the first in which NLR was investigated in MDD. The findings of the study reveal that NLR tends to be higher in patients with MDD, and a high NLR value supports the view that inflammation is a critical factor in the etiology of MDD.

We investigated whether prolidase activity has a diagnostic test value in schizophrenia and assessed the relation between prolidase activity and sociodemographic-clinical characteristics of patients with schizophrenia. Fifty patients with schizophrenia (diagnosed as schizophrenia according to DSM-V criteria) and 50 healthy volunteers were included in this study. Case and control groups had a similar distribution in age, sex, body mass index (BMI), and smoking status. Serum prolidase activity was measured in both groups and was determined to be significantly higher in the patient group (509.706±41.918) compared to the control group (335.4±13.6; t=6.231; p=0.0001). A cut-off point of 392.65U/L prolidase was determined for diagnostic measures from the plotted ROC curve. The area under the ROC curve was 1.000, which was significant (p<0.0001). Higher values were assigned as the disease state. Both positive predictive value (PPV) and negative predictive value (NPV) were 100% at the cut-off point of 392.650U/L. The prolidase levels of the control group were all below the cut-off point. There were no statistically significant differences between the two groups with regard to age, gender, or BMI (p>0.05), and no correlation was found between mean prolidase activity and age of onset of the disease, family history, disease duration, number of hospitalizations, subtypes of schizophrenia, PANSS scores or sub-scores, CGI-S scores, S-A scale scores, and the antipsychotic treatment (p>0.05). The results of this study indicate that serum prolidase activity may be a useful diagnostic test for schizophrenia; however, further studies are needed to verify this.

ABSTRACT Objective: In the present study, we aimed to examine the relationship between the oxidative metabolism with disease severity, sociodemographic, and clinical characteristics in the patients with schizophrenia. Methods: Seventy-one patients with schizophrenia and 76 healthy volunteers were included in the study. Plasma total antioxidant level (TAL) and total oxidant level (TOL) were analyzed, and oxidative stress index (OSI) was calculated. Results: There was a statistically significant increase in TOL and OSI and decrease in TAL in the patients with schizophrenia compared to the controls (p < .05). There were positive, mild, statistically significant correlations between TOL, OSI, and Positive and Negative Syndrome Scale-Total scores (p = .01, p = .01, respectively), Positive and Negative Syndrome Scale-Negative scores (p = .002, p = .001, respectively), Positive and Negative Syndrome Scale Global Psychopathology scores (p = .03, p = .03, respectively), and Clinical Global Impression-Severity Scale scores (p = .008, p = .009 respectively). OSI levels were significantly lower in the patients who were on treatment with atypical antipsychotics (AAP) compared to the patients who were on typical antipsychotics (TAP) and combined antipsychotic (CAP) agents (p = .032). Conclusions: Oxidative stress was higher in schizophrenia patients. The increased severity of negative symptoms was in line with the disruption in oxidative balance. Oxidative stress is quite lower in AAP users compared to the TAP and CAP users. One of the mechanisms underlying the fact that AAPs are more effective on negative symptoms than typical agents may be the positive effect on the oxidative stress.

Background Suicide is an important health problem in Turkey as it is in all regions of the world. Suicidal behavior has multiple causes, which are broadly divided into those related to proximal stressors and those due to predisposition. Suicide statistics may be associated with mental health disorders, which are among the foremost predictors of suicide attempts. More than 90% of patients who commit suicide have a diagnosable psychiatric disorder, usually a major depressive disorder. Other major risk factors for suicide attempts are history of suicide attempts in the family, stressful life events, sleep disturbances, poor income, unemployment, severity of symptoms of depression, and anxiety. Sleep is a complex phenomenon. Sleep disturbances can therefore be contributed to the emergence of suicidal behavior allowing for the possibility of predicting future suicides. Methods We evaluated 106 patients who were admitted after suicide attempts to the Department of Psychiatry at Dicle University Faculty of Medicine. The recruited subjects were assessed by Structured Clinical Interview for DSM-IV Axis I disorders, and the intensity of symptoms was evaluated using the Beck Anxiety Inventory, Hamilton Depression Rating Scale, and Pittsburgh Sleep Quality Index. The mean values of the subjects attempting multiple and single suicides were compared using appropriate inferential statistical tests. Results Most suicide attempts are believed to be preventable. Our results revealed that a great variety of risk factors are associated with an increased risk for multiple suicide attempts. Most of these attempts appeared to be spontaneous and impulsive rather than planned. In particular, this study highlights the importance of previous suicide attempts, history of suicide in the family, history of stressful life events in the previous 6 months, poor income, unemployment, sleep disturbances, severe hopelessness with depression, and coexisting symptoms of anxiety as risk factors. Conclusion The first step in prevention of suicides is doubtlessly strong and reliable communication, due to the fact that the majority of subjects who commit suicide have had contact with a health professional during the month before the suicide.

Objective: The aim of this study is to investigate the presence of ADHD and other psychiatric disorders among parents with at least one child with ADHD relative to parents with children who do not have ADHD. Method: Eighty five parents of children with ADHD with 68 control parents who had healthy children without ADHD were interviewed for participation in present study. Each parent was evaluated for co-existing psychiatric disorders using the Structured Clinical Interview for the DSM IV Axis I Disorders (SCID I). Results: We found that ADHD and co-morbid psychiatric symptoms were increased in the parents of children with ADHD in comparison with the healthy control group. Conclusion: Psychiatric co-morbidity was more common among the parents of patients with inattentive and combined presentations. Adult ADHD is associated with psychiatric co-morbidities including anxiety disorders, mood disorders, and somatoform disorders as well as substantial role impairment.

Objective Human serum paraoxonase (PON1) prevents lipids from peroxidation and functions as an antioxidant mechanism. Malonyldialdehyde (MDA) is the final product of lipid peroxidation and can be used as an indicator of oxidative stress. The aim of this study was to investigate PON1, MDA, and arylesterase (ARY) levels in schizophrenic patients who are taking typical, atypical, or combined (typical and atypical) antipsychotic drug treatment, with respect to those of healthy controls. Methods We evaluated 41 patients (11 taking typical antipsychotics, 19 taking atypical antipsychotics, 11 taking combined anti-psychotics) and 43 healthy controls. Results MDA levels were higher in schizophrenic patients taking typical antipsychotics compared with healthy controls (p=0.001). ARY levels were higher in patients taking atypical antipsychotics compared with healthy controls (p=0.005). PON1 activity was similar in all groups. Conclusion Our results indicate that treatment with typical antipsychotic drugs could be related to increased MDA levels; and antipsychotic medication may increase PON1 levels in schizophrenic patients.

Wilson disease (WD) is an infrequent genetic disorder of copper metabolism (chromosome 13), with decreased transport of copper by hepatic lysosomes due to mutation in the Wilson disease protein (ATP7B) gene. Hence, accumulating copper is primarily affecting the liver, brain, cornea, and kidneys, after then leading to their symptomatic damages. During early ages, the patients are mostly presymptomatic. The worldwide prevalence was reported to be 1 in 30.000. Psychiatric symptoms are common with Wilson’s disease. Pychosis can be an initial manifestation and often leads to an inaccurate diagnosis. As is seen, clinical syndrome may be very complex. Therefore, detecting mental health disorders of secondary origin is very important for the mental health professionals. In conclusion, one must be aware of the possibility of an organic cause in patients who are admitted with psychiatric symptoms, for the first time. On the other hand, medical causes of psychiatric symptoms should always be considered. Here, we report on a case of psychotic disorder due to Wilson’s disease, presenting with psychotic symptoms and bizarre behaviour.

Skin picking (excoriation) disorder is the recurrent excoriation of ones own skin, resulting in noticeable skin damage. People pick their skin for different reasons. For the majority of patients, first skin picking is associated with a history of childhood abuse and personal problems. Subjects who moderately to severely cause injurious self-harm are more likely to have a history of exposure to domestic violence and childhood abuse than those who do not self-harm. At the same time, these conditions could be related to the etiology for majority of other psychiatric disorders. We report herein, a case of a patient with skin picking disorder who had a history of childhood physical and emotional abuse with borderline personality disorder.

Background Deltamethrin (DLM) is a broad-spectrum synthetic dibromo-pyrethroid pesticide that is widely used for agricultural and veterinary purposes. However, human exposure to the pesticide leads to neurotoxicity. Glutamine is one of the principal, free intracellular amino acids and may also be an antioxidant. This study was undertaken in order to examine the neuroprotective and antioxidant potential of l-glutamine against DLM toxicity in female Wistar albino rats. Materials and methods The rats were divided into the following groups (n=10): Group I: control (distilled water; 10 mL/kg, po one dose), Group II: l-glutamine (1.5 g/kg, po one dose), Group III: DLM (35 mg/kg, po one dose), and Group IV: DLM (35 mg/kg, po one dose) and l-glutamine (1.5 g/kg, po one dose after 4 hours). Total oxidant status (TOS), total antioxidant status (TAS), tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 levels and apoptosis were evaluated in brain tissue. Results DLM-treated animals had a significant increase in brain biochemical parameters, as well as TOS and TAS. Furthermore, the histopathological examination showed neuronal cell degeneration in the cerebral tissue. l-Glutamine treatment decreased the elevated brain levels of TOS and neuronal cell degeneration. There was no difference in tumor necrosis factor-α, IL-1β, and IL-6 levels between the groups. Conclusion l-Glutamine may reduce the toxic effects of DLM in the cerebral tissue through antioxidant properties.

Paliperidone is an atypical antipsychotic drug used to treat schizophrenia. Paliperidone can cause some rare side effects during treatment. Despite many publications of mania and hypomania induced by antipsychotics, mania cases induced by paliperidone are few in the literature. In this case a schizophrenia patient showing symptoms of mania during usage of paliperidone with a dose of 9 mg/day in which the symptoms rapidly disappeared after discontinuation of paliperidone and initiation of aripiprazole was reported. Clinicians should be aware of that Paliperidone treatment may trigger mania symptoms. J Clin Exp Invest 2015; 6 (3): 321-323
