The change in symptoms necessary to be clinically relevant in obsessive-compulsive disorder (OCD) is currently unknown. In this study, we aimed to create an empirically validated threshold for clinical significance or minimal important difference (MID).

We analyzed individual participant data from short-term, double-blind, placebo-controlled registration trials of selective serotonin reuptake inhibitors in adult OCD patients. Data were collected from baseline to week 12. We used equipercentile linking to equate changes in the Clinical Global Impression (CGI) scale to changes in the Yale-Brown Obsessive-Compulsive Scale (YBOCS). We defined the MID as the YBOCS change linked to a CGI improvement of 3 (defined as “minimal improvement”).

We included 7 trials with a total of 1216 patients. The CGI-scores and YBOCS were moderately to highly correlated. The MID corresponded to 4.9 YBOCS points (95% CI 4.4–5.4) for the full sample, or a 24% YBOCS-decrease compared to baseline. The MID varied with baseline severity, being lower in the group with mild symptoms and higher in the group with severe symptoms.

By linking the YBOCS to the CGI-I, this is the first study to propose an MID in OCD trials. Having a clearly defined MID can guide future clinical research and help interpretation of efficacy of existing interventions. Our results are clinician-based; however, there is further need for patient-reported outcomes as anchor to the YBOCS.

Obesity-related cardiometabolic comorbidity is common in major depressive disorder (MDD). However, sex differences and MDD recurrence may modify the MDD-obesity-link.

Sex-specific associations of MDD recurrence (single [MDDS] or recurrent episodes [MDDR]) and obesity-related traits were analyzed in 4.100 adults (51.6% women) from a cross-sectional population-based cohort in Germany (SHIP-Trend-0). DSM-IV-based lifetime MDD diagnoses and MDD recurrence status were obtained through diagnostic interviews. Obesity-related outcomes included anthropometrics (weight, body mass index, waist- and hip-circumference, waist-to-hip ratio, waist-to-height ratio), bioelectrical impedance analysis of body fat mass and fat-free mass, and subcutaneous (SAT) and visceral adipose tissue (VAT) from abdominal magnetic resonance imaging. Sex-stratified linear regression models predicting obesity-related traits from MDD recurrence status were adjusted for age, education, and current depressive symptoms.

790 participants (19.3%) fulfilled lifetime MDD criteria (23.8% women vs. 14.5% men, p<0.001). In women, MDDS was inversely associated with anthropometric indicators of general and central obesity, while MDDR was positively associated with all obesity-related traits, except waist-to-hip ratio and fat-free mass. In women, MDDR versus MDDS was associated with higher levels of obesity across all outcomes except fat-free mass. In men, MDD was positively associated with SAT regardless of MDD recurrence. Additionally, lifetime MDD was positively associated with VAT in men. Results remained significant in sensitivity analyses after exclusion of participants with current use of antidepressants.

The MDD-obesity association is modified by MDD recurrence and sex independent of current depressive symptoms. Accounting for sex and MDD recurrence may identify individuals with MDD at increased cardiometabolic risk.

Hungarians exhibit more negative attitudes toward help-seeking for mental health problems compared to other European countries. However, research on help-seeking in Hungary is limited, and it is unclear how stigma relates to help-seeking when considering demographic and clinical characteristics. We used a network analytic approach to simulate a stigma model using hypothesized constructs in a sizable sample of Hungarian adults.

Participants were 345 adults recruited from nine primary care offices across Hungary. Participants completed self-report measures assessing public stigma, self-stigma, experiential avoidance (EA), attitudes toward seeking professional psychological help, anxiety, depression, demographics, prior use of mental health services, and whether they have a family member or friend with a mental health condition.

EA and anxiety were the most central nodes in the network. The network also revealed associations between greater EA with greater public stigma, anxiety, depression, and having a family member or friend with a mental health condition. More positive attitudes toward seeking help were associated with lower self-stigma, public stigma, and having received psychological treatment in their lifetime. Being female was associated with lower income, higher education, and having received psychological treatment in their lifetime. Finally, having a family member or friend with a mental health condition was associated with having received psychological treatment in their lifetime and greater public stigma.

The strength centrality and associations of EA with clinical covariates and public stigma implicate its importance in stigma models. Findings also suggest that while some aspects of existing stigma models are retained in countries like Hungary, other aspects may diverge.

This prospective study aimed to assess couples’ psychological status during the perinatal period to identify those at risk for postpartum depression.

Conducted at Lyon University Hospital from March to July 2022, the study enrolled pregnant women without progressive psychiatric disorders or obstetric risk factors, and their partners. Participants completed the Edinburgh Postnatal Depression Scale (EPDS) at three points: during the 9th month of pregnancy, immediate postpartum, and 6–8 weeks after delivery. A score ≥10 on the EPDS indicated depression risk. A score ≥10 on the EPDS indicate depression risk. The primary endpoint was EPDS scores throughout the perinatal period.

Ninety-five couples participated; 96% of patients and 68% of partners completed pre-delivery questionnaires, 81% and 71% during maternity stay, and 64% and 46% postpartum, respectively. Overall, 15% of patients and 1% of partners had EPDS scores >10 in the postpartum period. Psychiatric history and emergency cesarean sections were associated with higher immediate postpartum EPDS scores in patients [Beta 3.7 points, 95% CI 0.91; 6.4 and Beta 5.2 points, 2.2; 8.1, respectively]. Episiotomy was associated with higher EPDS scores in partners. No significant association between the different factors studied and the EPDS score was found at 6–8 weeks postpartum in patients nor their partners.

While specific risk factors for persistent perinatal depression in couples were not identified, a notable proportion of patients exhibited high EPDS scores. Screening all couples during prepartum and postpartum periods is crucial, regardless of identified risk factors.

As part of the intervention, patients with severe schizophrenia who are cared for in psychiatric rehabilitation units need psychological treatments. However, there is great variability within the psychotherapy alternatives that are proposed for rehabilitation in schizophrenia, and it is necessary to know which are the most efficient interventions in order to prioritize their inclusion in intervention programs.

To know the level of evidence of the existing psychotherapy alternatives for the rehabilitation treatment in schizophrenia through the systematic review of recently published studies.

Consecutive systematic searches in the scientific literature were used in a sensitive and specific way, aimed at identifying the existence of documents in databases and clinical practice guidelines based on evidence of psychological treatment in schizophrenia. Psychosocial and social approaches and family members interventions were excluded, and the search was limited to the last 5 years. The PICO format has been used, and a subsequent critical reading using the AGREE II tool, considering the inclusion criteria of presenting a score >60% in 4 domains.

The following interventions have been found to be therapeutically effective: Level 1B (Early intervention in Psychosis; Patient and Family psychoeducational intervention; Basic ando social skills training; Social cognition and Metakognition training; Cognitive Remediation; Cognitive Behavioral Individual Therapy; Assertive Community treatment; Supported employment). Level 2B (Family Problem Solving Therapy, Dynamic Psychotherapy; Cognitive Behavioral Group Therapy); Level 2C (Horticultural, Art, Music, Animals Therapies).

Several psychotherapy alternatives are proposed for rehabilitation in schizophrenia, with known level of evidenca in order to prioritize their inclusion in intervention programs.

In general, resilience is a process in which the interplay of risk and protective factors of the system itself and its environment is balanced in such a way that positive development opportunities open up. The resilience of a person, a system and a profession is therefore reflected in the ability to shape conditions in such a way that positive coping with challenges and crises is possible as a basis for positive further development. The time of the pandemic and the war in Ukraine has led to a large number of adjustments to psychology as a science, as a profession and as a perspective on life. This is associated with opportunities for positive further development of the discipline. European psychology has so far mastered the challenge of the pandemic and the war in Ukraine very well. The task now is to harness its successes as a multifunctional hub for other sciences, professions and society as a whole. The aim is to develop an identity that strengthens the unity of psychology in its diversity. With wisdom and resilience, psychology is also increasingly facing up to the challenges expressed in the United Nations Sustainable Development Goals (UN SDGs). In the discussion of social and professional change, the possibilities for a joint positive development of all professions in these stressful times become clear.

Sleep quality depends on several factors such as smoking, physical activity, diet, and certain pathologies, namely obstructive sleep apnoea syndrome. Indeed, following their vaccination against COVID19, several medical trainees complained about a deterioration of their sleep quality.

To evaluate the quality of sleep of medical trainees who work at Charles Nicolle Hospital and who were vaccinated against SARS-COV2.

We conducted a descriptive cross-sectional study among medical trainees at Charles Nicolle Hospital who were vaccinated against COVID-19 during the period from March 2020 to August 2022. Sleep quality was evaluated by the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Trainees were contacted during the period August 2022 to September 2022.

Sixty-nine medical trainees, vaccinated against Covid19 joined our study. Forty-nine of them had a significant sleep disturbance: Pittsburgh Sleep Quality Index (PSQI) greater than five. The average age was 29.39±3.04 years with a female majority (73.5%). No psychiatric history was found. The most affected category of trainees were residents (71.4%). Forty-three of them were inoculated with the messenger RNA vaccine and 4 with inactivated vaccine. Twenty-one patients vaccinated with the messenger RNA vaccine received two doses, seventeen received three doses and only one received a single dose. Sleep latency was high in 20,4% of cases. A sleep duration of less than five hours per night was found in 18,4% of the cases. Six participants reported using a sleep aid three to four times a week.

Our study revealed a significant sleep disturbance in medical trainees at Charles Nicolle Hospital. This could be due to the SARS-COV2 vaccination but can also be explained by the night shifts and the stress to which they are exposed, especially during this pandemic period.

Paliperidone Palmitate (PP) is an atypical antipsychotic, approved by the FDA for acute and maintenance treatment of schizophrenia and schizoaffective disorder.

It has a relatively safety profile, and reported cases of paliperidone palmitate-induced angioedema or anaphylaxis are uncommon.

We intend to present a case of paliperidone palmitate-induced anaphylaxis to alert clinicians regarding this rare, but possible complication.

Non-systematic review of the literature and report of a case study.

Long-acting injectable Paliperidone Palmitate (LAIPP) is a safe and effective alternative to oral Paliperidone, with less incidence of disease relapse related to medication non-compliance.

Substance use disorder (SUD) is highly prevalent in first-episode psychosis (FEP), and it is associated to decreased treatment compliance, which impairs the outcomes of these patients. Therefore, several authors have been recommended long-acting injectable antipsychotics (LAI-AP), such the LAIPP, as a first line for treatment of FEP-SUD patients.

The most common side effects associated with LAIPP are injection site reactions, extrapyramidal symptoms, hyperprolactinemia, sedation, hypersalivation, orthostatic hypotension, tachycardia, and weight gain. Hypersensitivity reactions have rarely been reported and may be dose-dependent.

We report a case of a 20-year-old female, without medical history and no history of allergies, who was medicated with once-monthly LAIPP at dose 100 mg for the maintenance treatment of a first psychotic episode associated with cannabis abuse.

Approximately 24 hours after the first monthly injection dose, she was admitted in the emergency room (ER) presenting an increasing angioedema associated with stridor, requiring endotracheal intubation and administration of adrenaline, clemastine and hydrocortisone during the assessment in the ER.

After clinical stabilization, she was transferred to the internal medicine ward, and following a full recovery, she was discharged 6 days later while being medicated with Olanzapine 15 mg/day, Lorazepam 3 mg/day and Sertraline 50 mg/day. LAIPP was suspected as the etiology of the anaphylaxis reaction due to temporal relationship of its onset with therapy administration and by the exclusion of other potential causes. Consequently, LAIPP was discontinued at discharge.

This report shows the possibility of a late and potentially life-threatening anaphylactic reaction to LAIPP. So, all physicians should be aware of this potential complication, which requires timely recognition and management.

Modern authors characterize hyperthymic individuals as eloquent, humorous, self-confident, optimistic, energetic, liberated, sexually active, constantly planning and implementing their plans. Four or more of the listed characteristics indicate the individual’s involvement in the circle of hyperthymic people. Statistical data on the prevalence of hyperthymic is scarce, which is due to rare requests for help and the diagnosis of this condition not as a disease, but within the framework of characterological traits. Attempts to classify hyperthymics have been made more than once, but previously none of the authors divided them according to the presence of side character traits in the personality structure.

To establish psychopathological types of hyperthymic individuals in whom affective states were formed.

The sample consisted of 50 patients (42 women, 8 men) who were on inpatient or outpatient treatment at the clinic since 2019 to 2022. Patients were examined by clinical-psychopathological, clinical-anamnestic methods due to the presence of a phase affective state.

Four types of hyperthymic personalities have been identified: anxious-hyperthymic, hysterical-hyperthymic, schizoid-hyperthymic and standard hyperthymic. Anxious-hyperthymic type, 20% (n=10) characterized by a combination of increased activity, sociability with such traits as suspiciousness, perfectionism, meticulousness, exactingness, concern for one’s health and the desire to maintain a healthy lifestyle. Hysterical-hyperthymic type, 46% (n=23) includes both hyperthymic and hysterical traits in the form of increased emotionality, egocentrism, drama, and desire for recognition from others. In addition, patients in this group are characterized by increased concern about their appearance (bright clothes, makeup, tattoos). Schizoid-hyperthymic type, 10% (n=5). In addition to increased activity and emancipation, patients in this group are prone to fantasizing, overvalued hobbies, sthenicity, emotional poverty and rationalism. Standard type, 24% (n=12) are characterized by the presence of typical hyperthymic traits - optimism, energy, constant desire for productive activity, success in the chosen profession, rapid career growth, sociability, openness.

Hyperthymic individuals with the development of affective phases are heterogeneous in their psychopathological structure and have features of the pathocharacterological structure that make it possible to distinguish anxious-hyperthymic, hysterical-hyperthymic, schizoid-hyperthymic and standard types. The developed classification of hyperthymia reveals the predominance of the hysterical-hyperthymic type (46%).

First episode psychosis (FEP) is the first manifestation of psychotic disorders lasting at least one week, but not longer than 2 years, causing personal suffering and decreased functional outcome of patients. The early intervention in FEP is crucial. Published results on early intervention programmes indicate that during the first 5-10 years relapse prevention and functional outcomes can be improved and mental health care costs can be reduced, compared to treatment as usual.

Our objective was to examine FEP patients at the Department of Psychiatry and Psychotherapy. Our aim was to create a homogeneous sample and identify factors that can help in early differential diagnosis and therapy. Our goal was to compare the neuropsychological performance and MRI results of patients and healthy controls.

Male and female inpatients hospitalized at our department due to a first psychotic episode and consenting to participate were included, since 2019 October. Cases with drug induced psychosis and organic background in the etiology of the psychotic episode were excluded. Male and female healthy controls were matched by age and education. Including healthy controls is still in progress. The duration of the project is 36 months, 24 months for recruiting patients and healthy controls, 12 month for analyzing data. The investigation includes detailed clinical, neuropsychological examination (baseline, 6th, 12th, 18th, 24th month) and MRI (baseline and in the 24th month).

Forty patients and sixteen healthy controls were included. 60% of the patients were rehospitalized due to relapses. Neuropsychological tests (RBANS, faux pas, Baron-Cohen eyes test) indicate cognitive dysfunction compared to healthy subjects. Using resting state fMRI second level analysis we found alterations in thalamo-cortical connectivity. We found significant differences in the connectivity of the thalamus and frontal lobe, postcentral gyrus, insula and cerebellum.

Our FEP research, although limited by the COVID-19 pandemic, shows promising results that can help in better understanding of the underlying factors of psychotic disorders.

Alzheimer’s disease is characterized by the presence of β-amyloid deposits in senile plaques and brain vessels. β-amyloid stimulates the glial release of proinflammatory cytokines, reactive oxygen species (ROS), or nitric oxide (NO), which are potentially toxic to neurons. One potential therapy for Alzheimer’s disease is the use of agents that inhibit the aggregation and formation of insoluble β-amyloid deposits in the brain, or break down the aggregates that have already formed, thus preventing their toxicity.

This study aimed to evaluate the effect of ovocystatin on the formation and destabilization of β-amyloid aggregation.

The effect of ovocystatin on β-amyloid aggregation was determined by Thioflavin T (ThT) Assay and Transmission Electron Microscopy (TEM). The impact on PC12 cell viability was determined by MTT assay.

Ovocystatin can interact directly with Aβ42, inhibiting its aggregation and reducing the toxicity induced by aggregated forms of β-amyloid. All effects are dose-dependent. Additionally, a significant increase in the PC12 cell viability treated simultaneously with Aβ42 and ovocystatin was observed.

Ovocystatin may be an important factor in the prevention and treatment of Alzheimer’s disease by regulating the conversion of monomeric β-amyloid into larger and potentially more toxic particles. However, the mechanisms of inhibition of amyloid fibrillar protein formation and/or destabilization by ovocystatin are still unclear and require further investigation.

A person diagnosed with a psychiatric illness, must face labels and discriminiation most of the time. Fear of these undermines the motivation of people in need to seek help. A special example of this phenomenon is the case of people experiencing homelessness and mental disorder, avoiding the additional stigma of homelessness and therefore do not seek any help for their mental ill-health. Availability of the specific services complicates their problem.

Fear of stigma, trauma, and previous bad experiences of using services also keep people experiencing homelessness away from services.

In Hungary, the February Third Working Group (F3) Report on the 2020 Homelessness Survey After the Penal Code - Before the Pandemic Homelessness - Services Perspectives by Péter Győri shows in his summary paper that only 29% had received psychiatric treatment.

Methodology Center of Social and Its Institutions (BMSZKI), in collaboration with the Awakenings Foundation, developed a complex rehabilitation service for people experiencing homelessness and mental disorder. This presentation aims to present this good practice.

Complex rehabilitation based on the methodology of community psychiatric care with the involvement of peer support.

• - provision of community psychiatric care for people experiencing homelessness and mental disorder,

• - introduction of screening for effective care of undiagnosed persons with mental disorders,

• - provision of outpatient and day hospital care

• - focus of care in accommodation services on persons with mental disorders,

• - the involvement of peer-support work in the service,

• - building a network of contact points, organizing case conferences,

• - developing and organizing training on recovery-based rehabilitation for people with mental disorders in cooperation between the two organizations,

• - telemedicine, making digital mental health available

• - presence of resources represented by self-help groups

• - running a working group to promote improvements based on practical experience homelessness and mental disorder.

extra-institutional teamwork multiplies the resources for people experiencing homelessness and mental disorder.

It is known that the formation of aggressive behavior is accompanied by neurodegenerative and neuroinflammatory changes. Immune cells have a regulatory effect on the central nervous system functions, including regulation of behavior.

We first demonstrated that ex vivo chlorpromazine - modulated immune cells have a positive aggressive behavior editing effect. The aim of the study was to investigate the influence of the indicated cells on some central mechanisms underlying the development of aggressive reactions.

(CBAxC57Bl/6) F1 aggressive male mice, developed in conditions of chronic social stress, were undergoing the transplantation of syngeneic spleen lymphocytes with ex vivo chlorpromazine-modulated functional activity. In recipients the immunohistochemical analysis was performed assessing the expression of the microglial marker Iba1. The levels of brain-derived neurotrophic factor (Bdnf) and cytokines was assessed by ELISA. For histological examination Nissl staining was applied.

Aggressive behavior editing after the chlorpromazine-modulated immune cells transplantation registered against the background of some structural and functional changes in the brain. It was found an increase in the density of pyramidal neurons in CA1 and CA3 hippocampal regions and augmented level of Bdnf. The decreased expression of microglial activation marker Iba1, accompanied with decreased levels of pro-inflammatory cytokines (IL-1β, IL-2, IL-6, INF-γ) and increased  anti-inflammatory (IL-4) cytokine was found. Visualization of functionally active lymphocytes pre-treated with chlorpromazine in the brain parenchyma of aggressive recipients suggests a direct effect of injected lymphocytes on CNS.

The effect of chlorpromazine - modulated immune cells that edits aggressive behavior is realized by stimulating neurogenesis, neuroplasticity and reducing neuroinflammation.

Gestational Loss represents a set of abrupt and unexpected losses throughout pregnancy or after childbirth. Every year, around two million babies die after 28 weeks of gestation, with between 14% and 20% of all pregnancies ending in loss. In most situations, pregnancy loss occurs in a pregnancy without signs of risk or irregularities, something that increases the shock and suffering felt by parents.

The present study aims to understand the relationship between pregnancy loss and parents’ grief experiences after spontaneous abortion, stillbirth or neonatal death with qualitative evidence.

This review followed the principles of PRISMA, and the search was carried out in the Web of Science and Scopus databases, aiming to find relevant articles about parental grief experiences resulting from pregnancy loss, published between 2012 and 2022. After research and analysis Of the studies, 15 qualitative studies were included.

The pain and sadness when experiencing the loss of a child was a common point in all the studies found. In this review, the majority of men revealed a duality in wanting to protect, physically and emotionally, their partner, while experiencing their own grief, something that led to the internalization of their emotions and the minimization of their pain. Grieving fathers and mothers report experiencing this process alone, describing the difficulty in expressing what they feel due to the lack of recognition of the loss. It was found that confrontation with other pregnant women leads bereaved parents to reveal jealousy and shame, as well as feelings of guilt. The farewell rituals, the process of writing and talking about their experience helped the women to not feel so alone and to find a purpose: to transform their pain and help other grieving mothers. Fathers and mothers who experienced pregnancy loss stated that the death of their child provided change and growth.

After Pregnancy Loss, adapting to the new reality is extremely painful, despite the work of mourning being necessary and crucial. This process is a search to integrate and accept the reality of the loss of the baby in a way that has meaning for the mother and father, it is the adaptation to a world without the lost child and to a relationship that had been built during the gestation period, which was violently broken. It is necessary for health professionals to be present and available to address these parents’ fears, provide advice and support.

Nurses working in psychiatric departments regularly encounter intricate, stress-inducing, and emotionally challenging situations. The mental well-being of these nurses directly influences the quality of care they deliver.

To assess the prevalence of psychological distress among psychiatric nurses and to identify the socio-demographic and clinical factors associated with it.

Cross-sectional, descriptive, and analytical study conducted over the course of one month from October 11th to November 8th 2023. Participants included were psychiatric nurses working in Razi Hospital, Tunisia. We collected data using pre-established questionnaire which included socio-demographic and clinical data of the participants. The assessment of psychological distress was conducted using the Depression, Anxiety and Stress Scale (DASS-21), validated in Arabic. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) in its 25th version

We collected data from 55 nurses working in Razi psychiatry hospital during the time of the study. Among them, 80% (n=44) were female. Their median age was 35 (Min=25, Max=62). Most of participants were married (81.8%, n=45) and 70.9 (n=39) had kids. In our sample, 5.5% (n=3) and 23.6% (n=13) had respectively personal psychiatric and somatic history. Some addictive behaviors were identified among our participants, especially smoking (14.5%, n=379) and alcohol use (3.6%, n=2).

Regarding working conditions, 81.8% (n=45) were assigned shift work. They worked in the men’s ward (43.6%, n=24), the women’s ward (34.5%, n=19), or in both (21.8%, n=12). Furthermore, 45.5% (n=25) reported witnessing a suicide attempt during their work, and 74.5% (n=41) were victims of aggression, primarily by patients (82.5%, n=33). Sixty percent (n=33) said expressed a desire to transfer.

Moderate to extremely severe depression, anxiety and stress was observed in respectively 34.5% (n=19), 61.8% (n=34) and 36.4% (n=20) of cases.

A significant association was found between stress among psychiatry nurses and personal somatic history (p <10-3). No further links were found between depression, anxiety, stress and other clinical factors.

These results emphasize the difficult working environment within psychiatric settings, emphasizing the critical requirement for specific interventions aimed at improving the mental health and well-being of psychiatric nurses.

The first psychotic episode is often a moment of utmost importance for the patients and their families, as well as for the treating professionals who need to address several dilemmas. Findings suggest that Self-Disorders (SD) specifically aggregate within schizophrenia spectrum disorders, pointing to the possibility that they could be a central phenotypic marker of schizophrenia spectrum disorders across the different severity of their clinical manifestations. We will present and discuss a case report involving a patient’s first admission, where diagnostic uncertainties exist. The goal is to enhance our comprehension of the significance of contemporary clinical and phenomenological psychopathology, with a specific focus on SD, in order to achieve a more accurate and precise assessment of incipient schizophrenia.

Bipolar disorder (BD) often has symptoms similar to other mental disorders (BD), and there are no paraclinical criteria for differential diagnosis. (Geoffroy et al. Bip Dis 2017; 5 7). Published work on MD proteomics is scarce and focused on schizophrenia. (Dmitrieva et al. PeerJ. 2022; 10 e13907). Therefore, it is important to study potential biomarkers of BD using easily accessible material—blood serum (Rhee et al. Transl Psy 2023; 13 44). Identification of proteins involved in the pathogenesis of BD will help in the study of the pathogenetic mechanisms of BD, the development of differential diagnostic methods and pathogenetically based drugs.

Carrying out a comparative proteomic analysis of blood serum from patients with BD and healthy individuals to identify potential biomarkers

We analyzed the protein spectrum of the blood serum of 14 patients with BD who were admitted during a depressive episode at the age of 32 [21;52] years with a disease duration of 8[5;11] years. The control group consisted of 10 mentally and somatically healthy individuals corresponding to the gender and age of the BD group. Blood serum was purified from 14 major proteins using affinity chromatography and separated by electrophoresis using the Laemmli method. After trypsinolysis, proteins were identified using HPLC/mass spectrometry on an Orbitrap instrument. Mass spectrometric analysis was performed on the Advanced Mass Spectrometry Core Facility of Skolkovo Institute of Science and Technology. Protein identification was carried out using the UniProtKB database using the Mascot search engine. The results were tested for significance using the nonparametric Fisher exact test with Yates correction.

In patients with BD, qualitative mass spectrometry revealed differential expression of 21 neurospecific proteins. Among them: Protein dispatched homolog 3, Ceroid-lipofuscinosis neuronal protein 6, SWI/SNF complex subunit SMARCC1, Neurogenic differentiation factor 4, Protein furry homolog-like, REST corepressor 1 – are involved in the proliferation, development and differentiation of neurons; Hemicentin-2, Dystrophin, Voltage-dependent L-type calcium channel subunit alpha-1D, Syntaxin-binding protein 5, Small conductance calcium-activated potassium channel protein 1– participate in synaptic transmission of ion transport and form receptors.

Studying the role of these proteins in BD and their quantitative content in a larger number of patients is promising. This will help in the development of new diagnostic criteria and targets for drug therapy for BD.
