The aim of the study was to analyse the prevalence of polypharmacy with antipsychotic drugs and analyse types of coprescribing episodes at the University Psychiatric Hospital in Serbia. A sample of 120 patients (198 hospitalisations) was analysed. The prevalence of polypharmacy was calculated as the proportion of patients receiving two or more antipsychotic drugs concomitantly for at least 28 days. Total daily antipsychotic drug load was calculated as the number of defined daily doses (DDDs) of drugs per patient per day. It was compared between patients receiving monotherapy and patients receiving polypharmacy. Statistics was performed using standard statistical methods. Monotherapy was prescribed during 32.3% hospitalisations (n = 64), while polypharmacy was noted in 67.7% (n = 134). Polypharmacy with two drugs was observed during 126 (63.6%) hospitalisations and three antipsychotics were prescribed concomitantly during 8 (4.1%) hospitalisations. Patients' characteristics were not significantly different between patients who received only monotherapy and patients receiving polypharmacy. Patients on monotherapy had significantly more prior hospitalisations than patients from the other group (t = 3.94, df= 119, p < 0.001). The prevalence of polypharmacy patient episodes (67.7%) is approximately 100% higher than the prevalence observed in developed European countries. The explanation of such prescribing habit of Serbian psychiatrists requires further investigation. The only distinguishing factor between patients receiving monotherapy and patients receiving polypharmacy is the number of prior hospitalisations. © 2007 John Wiley & Sons, Ltd.

Introduction. Fast and precise diagnostics of the disease from the large group of adult leukoencephalopathy is difficult but responsible job, because the outcome of the disease is very often determined by its name. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is caused by the mutation of Notch 3 gene on chromosome locus 19p13. Beside the brain arterioles being the main disease targets, extracerebral small blood vessels are affected by the pathological process. Clinically present signs are recurrent ischemic strokes and vascular dementia. CADASIL in its progressive form shows a distinctive pattern of pathological changes on MRI of endocranium. The diagnosis is confirmed by the presence of granular osmiophilic material (GOM) in histopathological skin biopsies. Case reports. Two young adult patients manifested ischemic strokes of unknown etiology, cognitive deterioration, migraine and psychopathological phenomenology. MRI of endocranium pointed on CADASIL. Ultrastructural examination of skin biopsy proved the presence of GOM in the basal lamina and near smooth muscle cells of arteriole dermis leading to CADASIL diagnosis. The presence of GOM in histopathological preparation is 100% specific for CADASIL. The patients were not searched for mutation in Notch 3 gene on chromosome 19, because some other leukoencephalopathy was disregarded. Conclusion. Suggestive clinical picture, distinctive finding of endocranium MRI, the presence of GOM by ultrastructural examination of histopathological skin biopsies are sufficient to confirm CADASIL diagnosis.

Background: Quality of life (QoL) is known to be indicative of the level of social functioning in mental health patients. However, the research on QoL, in the field of psychiatry, is not as comprehensive as it is in other domains of medicine. The aim of this study was to review the research evidence on QoL in psychiatric patients, published in Serbian medical journals during the last decade. Material and methods: The research data from studies on quality of life in psychiatric patients, published in Serbian medical journals from 2000 to 2009, were obtained by searching the databases Kobson and Medline. Results: We found eight studies on QoL in psychiatric patients published in Serbian medical journals from 2000 to 2009. The reviewed articles were focused on the comparison of QoL between psychiatric patients and healthy controls, or somatic patients, the research on the relationship of QoL and general psychopathology, and the research on QoL and medical treatment. Conclusions: QoL in patients suffering from mental disorders, as the outcome variable, is of a paramount interest in the follow-up treatment studies in psychiatry targeting critical issues of mental illness management strategies. QoL of psychiatric patients in Serbia is still under-researched, and it would be important to measure QoL from both a patient's and observer's (i.e. family members, friends, nursing staff, mental health professionals, etc.) perspective, in the context of social, economic, and cultural background of the patient. In the future, the studies on QoL in psychiatric patients in Serbia should also rely on "disease specific" assessment scales, which would consider particular aspects of psychopathology, and eventually follow up longitudinal course of mental illness, treatment outcome, and recovery. © Medicinska naklada.

Background Neutrophil-to-lymphocyte ratio (NLR) has been independently related to bipolar disorder (BD) and factors associated with suicidal risk. The aim of our study was to explore the relationship between NLR and suicide risk in euthymic BD patients. We also sought to propose a model of interaction between NLR and stress-diathesis factors, leading to suicidal risk in BD. Methods The study group consisted of 83 patients diagnosed with BD (36 suicide attempters; 47 suicide non-attempters), compared to the healthy control group (n = 73) and matched according to age, gender, and body mass index (BMI). NLR was measured according to the complete blood count. Mood symptoms have been assessed by Young Mania Rating Scale and Montgomery-Asberg Depression Rating Scale. Early trauma and acute stress were evaluated by Early Trauma Inventory Self Report-Short Form and List of Threatening Experiences Questionnaire, respectively. Suicide risk has been assessed by Suicide Behaviors Questionnaire-Revised (SBQ-R). Results Significant correlation was found between NLR and SBQ-R score. The main effects of suicide attempts on NLR, after covarying for confounders, were observed, indicating increased NLR in BD suicide attempters compared to healthy controls. We found significant moderatory effects of family history on NLR relationship to suicidal risk, with NLR being significant positive predictor of suicidal risk only in the patients with positive family history of suicide attempts. Conclusions The results suggest an enhancing effect of positive family history of suicide attempts on predictive effect of NLR on suicide risk. Our data support the idea that immune markers can predict suicide attempt risk in BD, but only in the subpopulation of BD patients with family history of suicide attempts. This could lead to prevention in suicide behavior in the patient population at particular risk of suicide. © 2016 Elsevier Inc. All rights reserved.

Background Affective temperaments are intermediate phenotypes for major affective disorders and are reported to have a neuroimmune etiopathogenesis. Here we investigated the role of soluble intercellular cell adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in affective temperaments and mood symptoms in healthy adults. Methods Healthy adults (n=94) were screened for psychiatric disorders using the nonpatient version of the Structured Clinical Interview for DSM-IV-I and II. Subjects with medical conditions associated with changes in inflammatory response were excluded, deriving the final sample (n=68). Affective temperaments were evaluated with Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A). State mood symptoms were assessed using the Young Mania Rating Scale and Montgomery–Åsberg Depression Rating Scale. Serum sICAM-1 and sVCAM-1 levels were measured using enzyme-linked immunosorbent assay. Results After adjusting for confounders (age, gender, BMI, and smoking habits), a high negative correlation between depressive and irritable temperament TEMPS-A scores and sVCAM-1 levels was detected. Although we identified no association between sICAM-1 levels and affective temperament scores, sICAM-1 was related to the state severity of manic symptoms. In a multiple linear regression model, sVCAM-1 remained a significant predictor of depressive but not irritable temperament scores. Limitations The temperaments were estimated on the basis of self-report questionnaire. Conclusions Our findings suggest that sVCAM-1 is related to affective temperaments, and it is a trait marker for liability to mood disorders. This relationship between alterations in cellular adhesion and affective temperament may be important for vulnerability to affective disorders. © 2016 Elsevier B.V.

Schizophrenia (SZ) is a neuroprogressive disorder presenting with biochemical, functional, and structural changes, which differ from early to late stages of the illness. We explored the differences in serum levels of soluble intercellular cell adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) between early and late stages of SZ, in regard to clinical characteristics and treatment application. Serum levels of sICAM-1 and sVCAM-1 were measured in 80 patients with SZ (40 early stage; 40 late stage), and compared with 80 healthy controls, matched by age, gender, body mass index, and smoking habits with each SZ group. Serum levels of sICAM-1 and sVCAM-1 were measured using ELISA. The severity of psychopathology was assessed using the Clinical Global Impression Scale and five-factor Positive and Negative Symptoms in Schizophrenia Scale. After adjustment for confounders, we noticed normal levels of sICAM-1 in the early stage, and elevated levels of sICAM-1 in the late stage of SZ. sVCAM-1 levels were decreased in both stages of SZ. Higher sICAM-1 levels have been related to more pronounced cognitive deficit and excitement symptoms in the early stage of SZ and to favorable characteristics of treatment application in both stages. SZ is associated with changes in the levels of adhesion molecules that vary from early to late stages of the illness. This implies that the concept of biochemical staging is applicable in SZ, at least for markers of cellular adhesion. © 2015 Elsevier Ltd.

Separation anxiety disorder (SAD) is a diagnostic category included in the group of anxiety disorders within DSM 5. Within ICD 10, SAD is in the group of disorders that occur only in childhood but the proposition of ICD 11 classifies SAD as a part of anxiety disorders, similarly to DSM 5. Although there are studies of the prevalence and most significant psychopathological phenomena that characterize SAD, there is still a distinctive lack of knowledge about this disorder like: its prevalence in the general and clinical population, its relation with other psychiatric disorders, or what is an effective therapeutic approaches to treating adults with this disorder. Some outstanding questions remain and there are no clear answers so far regarding the differentiation of “normality” and pathology related to the SAD, like: (1) is a strong relationship between family members the consequence of specific cultural and social patterns or a pathological pattern that indicates SAD?, or (2) are the pain and suffering resulting from separation from loved ones after wars, natural or other disasters “normal”/common/expected or are they psychopathological manifestations of SAD?, etc. In order to clearly identify SAD as an unambiguous psychopathological category, it is necessary to answer these questions in detail. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

Objectives: To explore the serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular cell adhesion molecule-1 (sICAM-1), tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in patients with bipolar disorder (BD), with regard to acute episode characteristics, course of the disorder and treatment. Methods: The study group consisted of 83 patients diagnosed with BD type I. The control group consisted of 73 healthy individuals, matched with the study group according to age, gender and body mass index. The serum levels of sVCAM-1, sICAM-1, TNF-α and IL-6 were measured by ELISA. Results: Compared with healthy controls, significantly elevated levels of IL-6 and sICAM-1 and significantly lower levels of TNF-α and sVCAM-1 were identified in acute and remission phases of BD. The acute serum levels of sVCAM-1 were associated with the type and severity of acute mood symptoms as well as with course of illness characteristics. TNF-α was associated with duration of untreated disorder and type of treatment. Conclusions: BD is related to both acute and long-term alterations of immune mediators, including adhesion molecules. The potential immunomodulatory role of pharmacotherapeutic treatment is also to be considered in BD. © 2016, © 2016 Informa UK Limited, trading as Taylor & Francis Group.

The blood–brain barrier (BBB) is formed by continuous, closely connected endothelial cells, enveloped in the basal lamina, pericytes, and foot extensions of astrocytes. BBB has a vital role in brain metabolism and protects the brain parenchyma from harmful agents present in the systemic circulation. Damage to the BBB and an increase in its permeability have an important role in many neurodegenerative diseases. This paper aims to review the literature on the impact of the BBB damage on psychiatric illness, a largely neglected and under-researched area. Links between BBB impairment and specific neuropsychiatric disorders are described including schizophrenia, affective disorders, dementias with behavioral disorders, and alcohol use disorder, with comparison to typical hereditary small vessel diseases affecting the BBB such as cerebral autosomal dominant arteriopathy with subcortical infarction and leukoencephalopathy and mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes. The authors critically summarize possible pathogenic mechanisms linking BBB damage and these common disorders. © 2022, Serbia Medical Society. All rights reserved.
