Association between total serum cholesterol and depression, aggression, and suicidal ideations in war veterans with posttraumatic stress disorder: a cross-sectional study.

AIM: To investigate the relationship between total serum cholesterol and levels of depression, aggression, and suicidal ideations in war veterans with posttraumatic stress disorder (PTSD) without psychiatric comorbidity. METHODS: A total of 203 male PTSD outpatients were assessed for the presence of depression, aggression, and suicidality using the 17-item Hamilton Depression Rating Scale (HAM-D17), Corrigan Agitated Behavior Scale (CABS), and Scale for Suicide Ideation (SSI), respectively, followed by plasma lipid parameters determination (total cholesterol, high density lipoprotein [HDL]-cholesterol, low density lipoprotein [LDL]-cholesterol, and triglycerides). PTSD severity was assessed using the Clinician-Administered PTSD Scale for DSM-IV, Current and Lifetime Diagnostic Version (CAPS-DX) and the Clinical Global Impressions of Severity Scale (CGI-S), before which Mini-International Neuropsychiatric Interview (MINI) was administered to exclude psychiatric comorbidity and premorbidity. RESULTS: After adjustments for PTSD severity, age, body mass index, marital status, educational level, employment status, use of particular antidepressants, and other lipid parameters (LDL- and HDL- cholesterol and triglycerides), higher total cholesterol was significantly associated with lower odds for having higher suicidal ideation (SSI≥20) (odds ratio [OR] 0.09; 95% confidence interval [CI] 0.03-0.23], clinically significant aggression (CABS≥22) (OR 0.28; 95% CI 0.14-0.59), and at least moderate depressive symptoms (HAM-D17≥17) (OR 0.20; 95% CI 0.08-0.48). Association of total cholesterol and HAM-D17 scores was significantly moderated by the severity of PTSD symptoms (P<0.001). CONCLUSION: Our results indicate that higher total serum cholesterol is associated with lower scores on HAM-D17, CABS, and SSI in patients with chronic PTSD.

Treatment-resistant schizophrenia and DAT and SERT polymorphisms.

One fifth to one third of all patients diagnosed with schizophrenia are resistant to drug treatment, which makes it a major clinical challenge. Genetic studies have focused on the association between treatment resistant schizophrenia (TRS) and a number of candidate genes, including serotonin and dopamine system genes. We explored associations between carefully characterized TRS and DAT-VNTR, SERT-PR and SERT-in2 polymorphisms. There were 173 patients enrolled in the study that were clinically evaluated using Positive and Negative Syndrome Scale and Clinical Global Impressions Scales and divided into two groups based on treatment resistance (92 patients in TRS group). Patients with a combination of SERT-in2 ll and DAT 9/10, 9/11, 9/9 and 6/6 genotypes were more likely to have TRS, compared to those with 10/10 or 10/12 genotype (OR=5.1; 95% CI=1.6-16.8). In the group of patients with DAT 10/10 or 10/12 genotype, those who also shared SERT-in2 ls or ss genotype were more likely to have TRS, compared to ll genotype carriers (OR=2.7; 95% CI=1.0-7.0). The model in which interaction between SERT-in2 and DAT polymorphisms is linked to TRS can possibly explain contradictory previous results regarding role of DAT and SERT in TRS, but further research is needed.

Changing the structure of the hospitalized patients at the Psychiatric Clinic Vrapce.

INTRODUCTION: Psychiatric treatment in developed countries has significantly changed in the last few decades, with a significant shortening of the duration of hospitalization. Numerous West European countries are undertaking health system reforms to improve treatment efficiency. OBJECTIVE: The aim of the study was to present the structure of hospitalized patients according to diagnostic categories of International Classification of Diseases and Related Health Problems - 10th Revision (ICD-10), and average duration of hospitalization from 2001 till 2010. METHODS: Data was collected from hospital medical charts for the period from 2001 till 2010 on the number of hospitalized patients, diagnosis and duration of hospitalization. RESULTS: Number of hospitalized patients increased by 27% (6309 vs. 8032). Average duration of hospitalization decreased for 45.1% (72.3 vs. 39.7 days), while the number of hospitalized patients decreased from 1284 (20.4%) in 2001 to 995 (12.4%) in 2010, the number of patients hospitalized because of depressive disorder increased from 309 (4.9%) in 2001 to 994 (12.4%) in 2010. The number of patients hospitalized because of enduring personality changes increased from 104 (1.7%) in 2001 to 449 (5.6%) in 2010. CONCLUSION: In the last decade the number of hospitalized patients suffering from schizophrenia at the Psychiatric Clinic Vrapce decreased, while the number of those suffering from depression and enduring personality change increased. The number of hospitalizations in the observed period increased overall. Observed changes can be explained by new therapeutic approaches, but also by objective social and economic factors and organization of the healthcare system.

Psychofarmacology in the prevention of somatic comorbid diseases in mentally ill patients.

It is a well known fact that mentally ill patients, especially those with schizophrenia, have a higher incidence of somatic diseases than the general population and finally a significantly shorter life expectancy. In this paper a comparison is made between schizophrenia and somatic comorbidity before the era of antipsychotics and after, with consideration to the prevalent morbidity during each of these periods. In the period before antipsychotics acute infectious diseases and TBC were the prevalent comorbid diseases. High comorbidity rates were due not only to epidemics but also poor treatment success, deficient health habits and poor personal hygiene. In the period after the discovery of antipsychotics significant changes in morbidity occurred with the prevalence of chronic degenerative diseases, primarily diabetes, hypertension and dyslipidemia. Studies show that new generation antipsychotics partly generate the occurrence of metabolic disorders, which makes it necessary to consider the choice of antipsychotic depending on the assessed risk in every individual case.

[Neuroradiologic diagnostics in patients hospitalized in Vrapce Psychiatric Hospital]. / Neuroradioloska dijagnostika hospitaliziranih bolesnika Psihijatrijske bolnice Vrapce.

The authors discuss the frequency of indication for and the results of CT and MRI brain scans in patients hospitalized in Vrapce Psychiatric Hospital. They wanted to contribute to the solving of the dilemma whether neuroradiologic tests should be a part of a routine diagnostic procedure in all psychiatric patients. Retrospectively, on the basis of case histories, the patients were analyzed in the first nine months of 2006. In this period 90 CT brain scans and two MRI brain scans were done, most often in the patients who were treated under the diagnoses of endogeneous psychoses, psychoorganic syndrome (dementia), affective disorders and epilepsy. Most CT findings (59%) and both MRI findings were normal. Abnormal findings were most often described as various forms of brain atrophy. Only one brain tumor was found. Electroencephalographic findings quite more often differed significantly from normal in the patients with abnormal CT findings compared with the patients with normal CT findings. The conclusion is that very small number of positive findings, except the brain atrophy, does not give good reason for routine CT and MRI brain scan in all hospitalized psychiatric patients. Indication must be made selectively on the basis of clinical psychiatric-neurologic evaluation. EEG, with limitations, can be of help in this matter.

Characteristics of patients who committed suicide during hospitalization in Psychiatric Hospital "Vrapce" in the period 1996-2006.

The aim of this study was to determine the characteristics of psychiatric inpatients who committed suicide in the Vrapce Psychiatric Hospital with respect to clinical, ethical, and legal context. The study included all patients hospitalized in the Vrapce Psychiatric Hospital between 1 January 1996 and 31 December 2006 who committed suicide (n = 25). The suicide rate in the observed period was 32.9 per 100.000 (suicide coefficient, 50), which is similar that in general population. Based on the characteristics of hospitalized patients who committed suicide, we obtained a typical profile as follows: a middle-aged person, single, unemployed, repeatedly hospitalized, with schizophrenia and a history of suicide attempts, committing suicide using a violent method after more than three weeks of hospital treatment. If further prevention of hospital suicide will be treated as a legal rather than medical issue, the hospital atmosphere would be totalitarian rather than therapeutic. The success of psychiatric treatment is the perception of both of these aspects of suicide as well as their efficient balancing.

QTc and psychopharmacs: are there any differences between monotherapy and polytherapy.

BACKGROUND: Some psychotropic drugs are connected with prolongation of QT interval, increased risk of cardiac arrhythmias and greater incidence of sudden death, especially when used in combination. Concomitant use of antipsychotics and antidepressants is not rare in our clinical practice. The study compares the length of QT interval in patients on monotherapy with an antipsychotic or an antidepressant and patients taking polytherapy (an antipsychotic agent combined with an antidepressant). METHODS: Sixty-one hospitalized women who met the ICD-10 criteria for schizophrenia, schizoaffective psychosis, delusional disorder and mood disorder were included in the study. The monotherapy group was consisted of thirty-two women treated with an antipsychotic or an antidepressant while the polytherapy group was composed of twenty-nine women treated with an antipsychotic agent plus an antidepressant. Two electrocardiograms (ECGs) were obtained for each patient: the first was carried out before the treatment and the second after two weeks of treatment.Statistical analysis was carried out by SPSS program and included unpaired and paired t test and Fisher's exact test. RESULTS: Mean baseline QTc values did not differ between the groups (439 +/- 22 ms was the same value found in the both groups; unpaired t test, p > 0.5). Mean QTc intervals after two weeks of treatment were also similar (439 +/- 24 ms in the monotherapy group and 440 +/- 20 ms in the polytherapy group; unpaired t test, p > 0.5). Fisher's exact test did not reveal significant difference in the number of patients with borderline (451-470 ms) or prolonged (> 470 ms) QTc between groups, neither before treatment nor after two weeks of treatment. Twenty two women of the total of sixty one patients (36%) had QTc > 450 ms before applying therapy. CONCLUSION: We did not find significant QT prolongation in our patients after two weeks of treatment with antipsychotics and/or antidepressants. The QTc interval length did not differ significantly in the monotherapy and the polytherapy group. More than one third of included women exceeded the threshold value of borderline QTc interval (450 ms) before starting treatment. This finding calls for caution when prescribing drugs to female psychiatric patients, especially if they have other health problems.
