Plasma asymmetric dimethylarginine (ADMA) concentrations in patients with first and multiple episode schizophrenia

An increasing number of reports in the literature indicate that asymmetric dimethylarginine (ADMA) regulates nitric oxide generation in numerous disease states. ADMA has been less studied in psychiatric disorders. The purpose of this study was to determine plasma ADMA concentrations in patients with schizophrenia compared to healthy controls. The study was conducted in 49 male patients with schizophrenia and 30 healthy male control subjects. The patient group was 24 first episode and 25 multiple episode schizophrenia participants. All schizophrenic patients were administered the Scale for the Assessment of Negative Symptoms, the Scale for the Assessment of Positive Symptoms (SAPS) and the Brief Psychiatric Rating Scale. Measurement of plasma concentrations of ADMA was accomplished by HPLC. There was a significant increase in the plasma ADMA concentrations in patients with schizophrenia when compared to healthy controls. There were no significant correlations between the plasma concentrations of ADMA and scores of psychiatric rating scales. In the multiple episode schizophrenia subgroup, the mean plasma ADMA concentration was significantly higher than in the first episode schizophrenia subgroup. The study indicate that plasma ADMA concentrations in patients with schizophrenia are elevated.

Asymmetric dimethylarginine (ADMA) and treatment response relationship in male patients with first-episode schizophrenia: A controlled study

Nitric oxide (NO) is thought to be involved in the pathogenesis of schizophrenia as well as many neuropsychiatric disease. Asymmetric dimethylarginine (ADMA) reduces the level of NO by inhibiting nitric oxide synthase (NOS) enzyme. In this study it is aimed to be investigated ADMA in patients with first-episode schizophrenia. In this study, according to DSM-IV diagnostic criteria for schizophrenia-like psychotic disorder, 49 male first-episode schizophrenia patients-whose mean age was 23.4±3.5 year-and age and education matched 30 healthy male subjects were included for comparison. ADMA levels of the patients were measured before and after 2 months of therapy. In order to rule out the conditions that may affect the levels of ADMA, people whose physical examination and laboratory findings were within normal range were included in the study. In this study plasma ADMA levels of first-episode schizophrenia patients and control group were 3.6±1.5 µmol/L and 1.02±1.02 respectively. After 2 months of antipsychotic treatment plasma ADMA levels of the schizophrenia patients decreased compared to baseline. There was no relationship between the ADMA levels and the clinical severity of the disease. It is considered to be the role of ADMA in the etiopathogenesis of schizophrenia.

Quality of sexual life in men with obstructive sleep apnoea

The study investigated the quality of sexual life of male obstructive sleep apnoea patients. Apnoea and non-apnoea participants were assessed with Golombok Rust Inventory of Sexual Satisfaction (GRISS) and Structured Clinical Interview for DSM-IV (SCID) before the sleep test. Folicule Stimulating Hormone (FSH), Luteinising Hormone (LH), prolactin, testosterone and oestrogen levels were also evaluated. The apnoea group had a higher BMI and lower LH and testosterone levels than the non-apnoea group. There were no differences between the apnoea, non-apnoea groups and within the apnoea groups (mild, moderate and high apnoea) in terms of sexual satisfaction. Although there was a change in the hormonal levels of obstructive sleep apnoea patients, the sexual life of apnoea patients was not affected at the clinical level.

Levels of serum immunomodulators and alterations with electroconvulsive therapy in treatment-resistant major depression.

Studies in recent years have indicated that neuroimmunological events and immune activation may have a place in the etiology of depression. It has been suggested from data that there is a causal relationship between activation of the immune system and excessive release of proinflammatory cytokines, such as interleukin 1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha), and the etiology of depression. Although the mechanism of action of electroconvulsive therapy (ECT) is unclear, there is evidence that it can reduce cytokines and immune system changes. In our study, we aimed to determine how levels of serum immunomodulators were affected by ECT in major depression patients. This study was conducted on 50 patients with treatment-resistant major depression. The data of the patients were compared with 30 healthy individuals with similar demographic characteristics. A clinical response occurred in the patients and at the end of therapy, IL-1, IL-6, TNF-alpha, IL-10, IL-4, and interferon-gamma levels were measured. The disease severity was assessed with the 17-item Hamilton Depression Rating Scale. Data analysis was performed using SPSS Version 15. Significant differences were determined between the patients with major depression and control group with respect to basal serum IL-1, IL-6, TNF-alpha, IL-10, IL-4, and interferon-gamma levels. ECT treatment was shown to reduce these differences. ECT may cause significant changes in the activity of the immune system. The consideration of the relationship between the immune endocrine neurotransmitter systems could contribute to new theories regarding the mechanism of antidepressant treatment and biology of depression.

The differences in temperament-character traits, suicide attempts, impulsivity, and functionality levels of patients with bipolar disorder I and II.

Background The primary aim of this study was to compare the differences in temperament–character traits, suicide attempts, impulsivity, and functionality levels of patients with bipolar disorder I (BD-I) and bipolar disorder II (BD-II). Methods Fifty-two BD-I patients and 49 BD-II patients admitted to Erenköy Mental and Neurological Disease Training and Research Hospital psychiatry clinic and fifty age- and sex-matched healthy control subjects were enrolled in this study. A structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition Axis I Disorders, Temperament and Character Inventory, Barrett Impulsiveness Scale-11 (BIS-11), Hamilton Depression Inventory Scale, Young Mania Rating Scale, and Bipolar Disorder Functioning Questionnaire (BDFQ) were administered to patients and to control group. Results No statistically significant difference in sociodemographic features existed between the patient and control groups (P>0.05). Thirty-eight subjects (37.62%) in the patient group had a suicide attempt. Twenty-three of these subjects (60.52%) had BD-I, and 15 of these subjects (39.47%) had BD-II. Suicide attempt rates in BD-I and II patients were 60.52% and 39.47%, respectively (P<0.05). Comparison of BD-I and II patients with healthy control subjects revealed that cooperativeness (C), self-directedness (Sdi), and self-transcendence (ST) scores were lower and novelty seeking (NS1 and NS2), harm avoidance (HA4), and reward dependence (RD2) subscale scores were higher in patients with BD-I. When BD-I patients were compared with BD-II patients, BIS-11 (attention) scores were higher in patients with BD-II and BIS-11 (motor and nonplanning impulsivity) scores were higher in patients with BD-I. According to BDFQ, relations with friends, participation in social activities, daily activities and hobbies, and occupation subscale scores were lower and taking initiative subscale scores were higher in patients with BD-I. Social withdrawal subscale scores were higher in patients with BD-II. Conclusion In our study, NS, HA, and RD scores that may be found high in suicide attempters and Sdi scores that may be found low in suicide attempters were as follows: NS1, NS2, HA4, and RD2 subscale scores were high and Sdi scores were low in patients with BD-I, suggesting a higher rate of suicide attempts in this group of patients. In addition, C and Sdi scores that indicate a predisposition to personality disorder were significantly lower in patients with BD-I than patients with BD-II and healthy controls, suggesting a higher rate of personality disorder comorbidity in patients with BD-I. Higher impulsivity and suicidality rates and poorer functionality in patients with BD-I also suggest that patients with BD-I may be more impulsive and more prone to suicide and have poorer functionality in some areas.

Suicide Attempt, Suicidal Ideation and Hopelessness Levels in Major Depressive Patients with and Without Alexithymia

Suicide attempt, suicidal ideation and hopelessness levels in major depressive patients with and without alexithymia Objective: It is known that hopelessness and alexithymia levels are increased in patients with depressive disorder. In the literature, reports are suggesting that high levels of hopelessness in patients with depressive disorder increase suicide attempts and ideations. Here we aimed to investigate whether there are any differences in terms of suicidal ideation, suicide attempt and hopelessness levels in major depressive disorder patients with and without alexithymia. Method: In this study, 99 patients diagnosed with major depressive disorder according to structured interview for DSM-IV (SCID-I/CV) and 50 healthy subjects were included. Sociodemographic questionnaire, Toronto Alexithymia Scale (TAS-20), Beck Hopelessness Scale (BHS), Scale for Suicidal Ideation (SSI) and Hamilton Rating Scale for Depression (HRSD) were administered to patients and controls. Additionally, Suicide Intent Scale (SIS) was administered to patients with suicide attempt. Results: There was no significant difference in terms of sociodemographic data (except for the marital status) between major depressive patients with or without alexithymia and healthy controls. According to a cut off point of 61 for TAS-20, 34.3% (n=34) of the patient group was alexithymic and 65.7% (n=65) was non-alexithymic. Rate of suicide attempt was higher in the alexithymic major depressive patients (67.6%) than the non-alexithymic major depressive patients (29.2%). Mean scores of SSI and BHS were higher in alexithymic patients than non-alexithymic patients. There was a positive correlation between TAS-1 (difficulty identifying feelings), TAS-2 (difficulty expressing feelings) and BHS, SSI scores. Conclusion: In our study, suicidal ideation, suicide attempt and hopelessness levels were higher in major depression patients with alexithymia. Higher incidence of suicide attempts in major depressive patients with higher alexithymia levels and higher suicidal ideation and hopelessness levels in this group of patients suggest the possibility of alexithymia being a predictive factor for suicide attempt.

The Relationship between the Number of Manic Episodes and Oxidative Stress Indicators in Bipolar Disorder

Objective Bipolar disorder (BD) is a chronic mood disorder characterized by recurrent episodes that has a lifetime prevalence of 0.4–5.5%. The neurochemical mechanism of BD is not fully understood. Oxidative stress in neurons causes lipid peroxidation in proteins associated with neuronal membranes and intracellular enzymes and it may lead to dysfunction in neurotransmitter reuptake and enzyme activities. These pathological processes are thought to occur in brain regions associated with affective functions and emotions in BD. The relationship between the number of manic episodes and total oxidant-antioxidant capacity was investigated in this study. Methods Eighty-two BD patients hospitalized due to manic symptoms and with no episodes of depression were enrolled in the study. Thirty of the 82 patients had had their first episode of mania, and the other 52 patients had had two or more manic episodes. The control group included 45 socio-demographically matched healthy individuals. Serum total antioxidant capacity (TAC) and total oxidant capacity (TOC) measurements of the participants were performed. The oxidative stress index (OSI) was calculated by TOC/TAC. Results There were no significant differences in OSI scores between BD patients with first-episode mania and BD patients with more than one manic episode. However, OSI scores in both groups were significantly higher than in the control group. TOC levels of BD patients with first-episode mania were found to be significantly higher than TOC levels of BD patients with more than one manic episode and healthy controls. There were no significant differences in TAC levels between BD patients with first-episode mania and BD patients with more than one manic episode. TAC levels in both groups were significantly higher than in the control group. Conclusion Significant changes in oxidative stress indicators were observed in this study, confirming previous studies. Increased levels of oxidants were shown with increased disease severity rather than with the number of manic episodes. Systematic studies, including of each period of the disorder, are needed for using the findings indicating deterioration of oxidative parameters.

Psychiatric evaluation of organ donor candidates in a university hospital and their anxiety, depression and quality of life levels

Psychiatric evaluation of organ donor candidates in a university hospital and their anxiety, depression and quality of life levels Objective: The aim of this study was to conduct a psychiatric evaluation of organ donor candidates and to investigate their levels of anxiety, depression and quality of life. Material and Methods: This study was performed between May 2015 and February 2016. It included 102 volunteers. The socio-demographic Data Collection Form, DSM-IV Clinical Interview Form – Clinical Version Structured for Axis Diagnoses (SCID-I/CV), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Symptom Checklist (SCL-90-R), and SF-36 Quality of Life Survey (SF-36) were administered to the patients. Results: The average age of the applicants was found to be 41.64±12.02, 42.2% (n=43) being male and 57.8% (n=59) being female. When it comes to the degree of affinity between potential donors and recipients, 57.8% (n=59) were first-degree relatives, 19.6% (n=20) were spouses, and 22.5% (n=23) were other relatives and/or close relations. By dividing donor candidates into groups by the degree of their affinity to recipients, there were statistically significant differences revealed between BDI, BAI and SCL-90-R total scores and interpersonal sensitivity subscale scores. Conclusion: As compared to the global average, the number of living donors is higher than cadaver donors; and donor candidates mostly comprise spouses and first-degree relatives. Therefore, family members and first-degree relatives who are affected directly or indirectly by the transplant process are exposed to social and psychological effects more as the donor candidates/donors. It is of crucial importance to evaluate the psychosocial states of donors, in addition to recipients, in order to manage the long-lasting transplant process, a treatmentand caredemanding one in a more appropriate way.

Possible relationship between amino acids, aggression and psychopathy.

Abstract Objective: Aggressive behaviour is associated with reduced serotonin metabolism in the brain, but there is not enough knowledge on potential changes of the serotonin precursor levels among violent offenders. In this study, we aimed to evaluate the relationships among the tendency of psychopathy, anger and the basic amino acids. Methods: Fifty-two young adult male patients with antisocial personality disorder (APD) and 30 healthy men included the study. Serum amino acid levels were measured by HPLC method. Aggression questionnaire and Hare Psychopathology Scale were used for all participants. Results: Blood levels of phosphoserine, aspartic acid, glutamic acid, aminoadipic acid and 1-methylhistidine in group of patients with APD were significantly higher than the control group. Blood levels of TRP, asparagine, citrulline, cystine, isoleucine, tyrosine, histidine, hydroxylysine, lysine, ethanolamine and arginine in the group of patients were found lower than the control group. A significant positive correlation between anger scores and histidine, methionine and GABA was found. GABA and methionine showed a significant correlation with the indirect aggression score. Conclusion: Our study showed a relationship between serum amino acid levels and the scores of aggression and psychopathy. We think that this is a productive research area for understanding the relationship among biochemical factors, aggression and psychopathy.

Remission of Episodic Sweating Attacks and Comorbid Depression in Shapiro Syndrome: Case Report

Shapiro syndrome, a rare disorder originally described by Shapiro and Plum in 1967, is characterized by episodic hypothermia and hyperhydrosis associated with agenesis of the corpus callosum. Proposed hypotheses to explain the clinical features of this syndrome include changes in the set point of the hypothalamic thermostat, increased norepinephrine (NE) release, and decreased plasma NE clearance. It was emphasized that the recognition of Shapiro syndrome in the evaluation of episodic hyperhydrosis is important. Here, we described a case with Shapiro syndrome who presented to our psychiatry clinic with recurrent episodic profuse sweating and depression. Sweating attacks and depression remitted after successful treatment with amitriptyline.
