Acute Stress Induced Catatonic Psychosis in an Adolescent: A Case Report
Authors: Yerlikaya Oral E. 
Published: August 2024

IntroductionChildhood maltreatment(CM) can precipitate a range of psychiatric disorders in individuals. Some research show that CM rates are as high as 85% in schizophrenia spectrum disorders (Larsson et al. 2013). This case report explores an instance of acute catatonic psychosis in an adolescent following a significant episode of physical and emotional abuse.ObjectivesThe aim is to elucidate the clinical presentation, diagnosis, and treatment of trauma-induced acute catatonic psychosis in an adolescent. The report seeks to emphasize the potential link between acute trauma and severe psychiatric disorders in young individuals.Methods
A thorough review of the patient’s clinical records was undertaken, focusing on psychiatric history, symptoms, treatment trials and responses. In parallel, an extensive literature review was conducted to understand the current knowledge on the association between acute traumatic stress and acute psychosis with catatonia.ResultsThe patient, a 16-year-old female, presented with severe symptoms of catatonia and psychosis including mutism, posturing, stupor, negativism, auditory hallucinations and persecutory delusions, in addition; eating refusal, urinary and fecal incontinence. Symptoms started immediately following physical and emotional abuse that occurred 10 days ago. She was hitted, insulted and detained for 2 days by her parent’s friends. Abuse reported to social services and judicial authorities. All laboratory and neurologic examinations performed to exclude an organic pathology. No pathologic results founded. Olanzapine 5 mg/day and lorazepam 0.5 mg/day started and titrated to 30 mg/day and 3.75 mg/day doses. Biperiden 4 mg/day started due to extrapyramidal side effects. A significant improvement observed about her catatonic and positive psychotic symptoms but she still had acute stress disorder symptoms. Trauma-focused cognitive-behavioral therapy added to her treatment. Family-based interventions examined for CM. She discharged in full remission after eight weeks of hospital stay. Lorazepam dose reduced and stopped before discharge.Conclusions
Neurobiological models are trying to enlight the association between experiencing highly stressful or traumatic events, such as child abuse, may impact on later expression of psychotic disorders by increasing stress sensitivity to later adversity (Fares-Otero et al. 2023). This case underscores the potential of acute traumatic stress to precipitate severe psychiatric disorders, including catatonia. It highlights the importance of comprehensive clinical evaluations and the inclusion of trauma history in children presenting with acute psychiatric symptoms. The findings advocate for the integration of trauma-focused interventions in the treatment of similar cases. Further research is needed to understand the pathophysiological mechanisms underlying this association and to develop effective treatment strategies for this vulnerable population.Disclosure of InterestNone Declared

Published: August 2024

IntroductionAntipsychotics effectively manage psychotic symptoms but may have side effects. Patients with schizophrenia often lack insight into their condition, leading to nonadherence. Long-acting injectable (LAI) antipsychotics aim to overcome this, reducing relapse risks. Paliperidone LAI, a second-generation antipsychotic, has a lower side effect profile when compared to first-generation counterparts. Blood dyscrasias, like neutropenia and lymphopenia, increase infection susceptibility. This case report describes an instance of leukocytopenia arising during paliperidone LAI treatment, which quickly resolved after the discontinuation of the medication.ObjectivesThis case report describes an instance of leukocytopenia arising during paliperidone LAI treatment, which quickly resolved after the discontinuation of the medication.MethodsResultsCASEA 42-year-old female with schizophrenia, nonadherent to previously prescribed medication was admitted to our acute psychiatric department. She experienced positive symptoms (paranoid delusions), as well as disorganized thinking and behavior. Oral risperidone 4 mg two times a day was recommenced and titrated with mild improvement in her psychotic symptoms with the idea of switching to paliperidone LAI and eventually ceasing oral medication. Oral paliperidone was unavailable for prescription due to local restrictions. At admission her routine laboratory tests showed no abnormalities, but 5 days after receiving paliperidone LAI, routine laboratory tests showed a strong decrease in her WBC and absolute neutrophilic and lymphocytic count ( Lkc 2.89x109/L, Neut 1.57x 109/L, Lym 0.88x 109 /L ). Antipsychotic-induced blood dyscrasia was suspected and paliperidone depot was discontinued. The patient had rapid improvement in her WBC reaching the reference range in 10 days ( Lkc 4.23 x 109/L, Neut 2.51x10 9/L, Lym 0.98x 109/L). Sertindole was introduced consdering her history of a good therapeutic response to the drug, with improvement in psychotic symptoms. She is currently stable taking sertindole 16 mg/day, clonazepam 2 mg/day and alprazolam 0.5 mg/day.DISCUSSIONThe onset of neutropenia and lymphopenia post-paliperidone LAI initiation, resolving in 10 days,, indicate a direct association. Few cases report to date describe paliperidone-induced leukocytopenia, with rapid recovery post-discontinuation. Proposed mechanisms include bone marrow suppression and peripheral WBC destruction. It has been proposed that drug-induced neutropenia is often dose-dependent, which could explain why our patient exhibited tolerability to risperidone but developed cytopenia upon transitioning to depot paliperidone.ConclusionsWhile cases of agranulocytosis have been reported in association with the use of other antipsychotics these antipsychotics do not require the same monitoring as clozapine. Our case emphasizes the need for vigilant blood dyscrasia monitoring during antipsychotic therapy.Disclosure of InterestNone Declared
Psychosocial difficulties as a predictor of overall functioning in individuals with schizophrenia: a case-control study
Authors: Mustoo Başer L. , Aydɪn O. 
Published: August 2024

IntroductionDifficulties in emotional, cognitive, behavioral, and social functions are considered important factors of global functioning in schizophrenia.ObjectivesA better understanding of difficulties in the mentioned facets might lead to the development of better-adjusted treatment approaches for individuals with schizophrenia, as well as impacting to reduction and elimination of stigma in Bosnia and Herzegovina’s wider social context in relation to difficulties spanning the daily life of individuals with schizophrenia.MethodsThirty- one patients with schizophrenia (SCH), and 30 healthy controls (HC) participated in our study. The Adult Self-Report (ASR), Achenbach’s scale for adults (ASEBA- Achenbach System of Empirically Based Assessment), and World Health Organization, Disability Assessment Schedule 2.0 (WHODAS 2.0) tests were administered.ResultsGroups differed in age, education, employment status, marital status, friendships existence, and disability existence. According to the regression equations, thought problems predicted Getting around; withdrawn predicted Getting along with people and Life activities- Household, School/Work in the group of individuals with schizophrenia.ConclusionsOur study revealed the role of different facets of difficulties in the prediction of global functioning in SCH. These findings might directly point to the importance of eliminating stigmatizing beliefs in a wider social context, developing techniques for improving the social support segment, focusing on healthy family functioning, as well as investigating job presence and perceived quality of life.Disclosure of InterestNone Declared
Schizophrenia and Risk of Dementia: A Literature Review.
Authors: Moraiti V. , Porfyri G. N. 
Published: August 2024

IntroductionDementia is a clinical syndrome affecting 1-2% of the population under the age of 65, while at older ages the frequency doubles every five years. The clinical manifestations include memory loss, communication deficits, agnosia, apraxia and executive dysfunction.Schizophrenia is a complex, chronic mental disorder affecting approximately 1% of the population, presenting with disturbances in perception, thought and behavior.ObjectivesTo investigate the relationship between schizophrenia and later-onset dementia; more specifically to explore whether schizophrenia increases the dementia risk.MethodsA review of 35 articles -from 2010 to 2023-
on PubMed and Google Scholar regarding patients with schizophrenia or other type of psychosis, who later presented dementia.ResultsPatients with a history of schizophrenia, schizotypal disorder, or delusional disorder are more likely to develop dementia.The greatest risk is presented in patients showing the shortest duration of psychotic symptoms (5 years or less), while at 5-10 years the probability of developing dementia decreases.The most common types of dementia occurring in psychotic patients are alzheimer’s disease (50-70%),vascular dementia (30%) and unspecified dementia (15%).Chronic patients (10+ years of symptomatology) are less likely to develop dementia. Psychotic patients over the age of 65 are more likely to develop dementia later in life, while individuals who develop schizophrenia after their 40s are three to four times more likely to present dementia compared to patients carrying a schizophrenia diagnosis before their 40s.Females with Late-Onset Schizophrenia have an increased dementia risk compared to males carrying the same diagnosis and compared to healthy females of the same age. Physical conditions implicated in the onset of dementia in schizophrenic patients include cardiovascular diseases, lung disease, substance and alcohol use, head injuries and diabetes.ConclusionsAccording to data, there is a strong correlation between schizophrenia and dementia.However, the related studies are limited in number, while their results require further investigation because of limitations (small sample sizes, co-morbidities, selection of chronic elderly patients).Furthermore, most of these studies were conducted in Western countries, highlighting the necessity of pursuing additional research.Disclosure of InterestNone Declared

Authors: Maruta N. O. , Kushnir Y. A. , Kalenska G. Y. 
Published: August 2024

IntroductionThe prevalence of schizophrenia in the world is between 0.4 and 1.4%, and the number of patients with negative symptoms (NS) in this group reaches 90%. NS are considered key components of schizophrenia that negatively affect social functioning (SF) and quality of life in patients with schizophrenia. The purpose of the study was to determine the features of SF among patients with NS in schizophrenia.ObjectivesFeatures of SF in 252 patients with NS in schizophrenia (main group) and in 79 patients with positive symptoms (PS) in schizophrenia (comparison group) were examined.MethodsA set of methods was used: Scale of personal and social functioning (PSP), which is a semi-structured interview and allows to assess the social status of patients, their functioning and satisfaction with the relevant field and statistical methods.Results
The analysis of the social and personal functioning of patients was carried out in four domains: socially useful activities, personal and social relationships, attention to oneself and one’s condition, restless and aggressive behavior patterns. In the sphere of socially useful activities, including work and study, in a significant part of patients with NS in schizophrenia, SF violations were expressed at moderate (41.27 ± 1.26) % and significant (33.33 ± 1.08) % levels. In the sphere of personal and social interaction, 41.27 % of patients had significant violations, 28.97% of patients had moderate violations, and 21.83% had severe violations in the social sphere. In the field of self-care, 21.83% of patients had no violations, in 36.90% - violations in self-care were weakly expressed, and in 26.19% of people - moderately expressed.When comparing the obtained results with patients with PS in schizophrenia, it was established that among patients with NS in schizophrenia there were more patients with significant impairments in the sphere of social activity (33.33%, p = 0.033, DC = 1.42, MI = 0, 07).. Patients with NS in schizophrenia were distinguished by a greater number of patients with significant impairments in the sphere of social interaction (41.27%, p = 0.001, DC = 2.58, MI = 0.24).. In the field of self-care, there were more persons with no violations among patients with NS in schizophrenia (21.83%, p = 0.008, DC = 3.33, MI = 0.20). There were more patients with the absence and weak expression of aggressive behavior patterns among patients with NS in schizophrenia (30.95%, p = 0.0001, DC = 10.87, MI = 1.55 and 45.63%, p = 0, 0001, DC = 6.54, MI = 1.16, respectively) in comparison with patients with PS in schizophrenia.ConclusionsThe obtained data should be taken into account when creating psychocorrective programs for patients with NS in schizophrenia.Disclosure of InterestNone Declared
Acute effects of intranasal ocytocin on affective empathy of patients with refractory schizophrenia and healthy controls: results of a randomized clinical trial
Authors: Osório F. D. L. , Ferreira A. C. 
Published: August 2024

IntroductionOxytocin (OXT) is a neuropeptide associated with social behavior and the modulation of neural circuits related to social cognition and emotion regulation. Schizophrenia is a mental disorder that causes impairment in different areas of social cognition, including empathy. A systematic review of the literature showed positive effects of exogenous administration of this hormone on the empathy of individuals without psychopathology, especially in the affective domain. Studies on the effect of OXT on empathy in patients with schizophrenia are very limited, being restricted to the cognitive domain.ations must be overcome in future studies. The effects associated with chronic use of the hormone should be the subject of future studies.Objectivesto evaluate the effect of a single dose of intranasal OXT (24UI) on affective empathy in individuals with refractory schizophrenia and healthy controls.Methodsa double-blind, randomized, placebo-controlled clinical trial was conducted. A convenience sample of 51 adult men (mean age 34.4 ± 7.6, >10 years of education) was recruited, 20 of whom were diagnosed with refractory schizophrenia according to the DSM-5 (exclusively using clozapine or clozapine + mood stabilizer and/or benzodiazepine) and 31 healthy controls. They were randomized into four groups and received OXT or placebo (PLA – vehicle: SCH-OXT (N=11), SHC-PLA (N=9), HC-OXT (N=15), HC-PLA (N= 16)). Before and after 50 minutes of administering the substance, they performed an affective empathy task (Multifaceted Emphaty Test – MET).Resultsthe baseline levels of affective empathy of patients with schizophrenia were lower compared to healthy controls when faced with negative stimuli (p=0.003), but not positive ones (p=0.39). After the administration of OXT and PLA (post-pre), a small increase in empathy levels was observed in all groups, which did not reach statistical significance (positive stimuli: ΔSCH-OXT = 0.16±1.08; ΔSHC-PLA= 0.53±1.44, ΔHC-OXT= 0.02±0.67, ΔHC-PLA= 0.24±0.45, p=0.85; negative stimuli: ΔSCH-OXT = 0.20±1.31; ΔSHC-PLA= 1.16±0.79, ΔHC-OXT= 0.12±0.99, ΔHC-PLA= 0.31±0.57, p=0.11).Conclusionsthe acute effects of intranasal OXT did not favor improvements in the levels of affective empathy, either in patients with schizophrenia or in healthy controls, contrary to the hypotheses of this study. The limited sample size and context-dependent aspects of OXT may explain these findings. These methodological limitations must be overcome in future studies. The effects associated with chronic use of the hormone should be the subject of future studies.Disclosure of InterestNone Declared

IntroductionThe prevalence of suicidal behavior in individuals diagnosed with Bipolar Disorder Type 1 is a topic of great concern within the field of psychiatry and mental health research. Bipolar Disorder Type 1 is characterized by extreme mood fluctuations that can contribute to a heightened risk of suicidal ideation, attempts, and completions in affected individuals.Objectives-To examine the socio-demographic and clinical profiles of Bipolar Type 1 patients admitted to the “C” psychiatry department at Hedi Chaker Hospital in Sfax, Tunisia.-To identify and understand the factors associated with suicidal behavior in this population.
MethodsWe conducted a retrospective descriptive and analytic study of hospitalized patients suffering from bipolar disorder type 1 in the psychiatry department “C”, Hedi Chaker Hospital, Sfax Tunisia from 2021 to 2023. Socioeconomic data and clinical profiles of patients were collected from archived files.Results
The total number of patients was 98, with an average age of 36.74 ± 12.3 years. The majority were single (67%), living with their families (76.5%), jobless (45.9%), and receiving family support (94.9%). In terms of psychoactive substance use, 81.6% have used tobacco, 46.9% have used alcohol, and 34.7% have used cannabis.Concerning family history, 55% of patients had at least one family member being treated for a mood disorder. Among them, 7.1% had attempted suicide, and 6.1% had died by suicide.Concerning the clinical profile of the study population, 28.6% had a personal somatic history. The diagnosis of bipolar disorder was made at the age of 27.52±8.6 years. 11.2% had a comorbid personality disorder with bipolar disorder.The majority of patients were on antipsychotics (95.9%), 84.7% were using mood stabilizers, 33.7% were prescribed anxiolytics, and only 4.1% were on antidepressants. Treatment compliance was poor in 61.2% of cases and 63.3% of patients had a poor insight.Ten percent of these patients had attempted suicide, 50% during a depressive episode, 50% occurring during a depressive episode, 30% during a manic episode, and 40% of attempts were related to discontinuation of treatment. 3.1% had used hanging, and 3.1% had engaged in voluntary drug ingestion as a method of self-harm. None of the suicide attempts necessitated intensive care hospitalization, but 60% of the individuals were admitted to psychiatric care. There was a statistically significant correlation between suicide attempts and a family history of suicide (p=0.049).ConclusionsBipolar patients face a heightened risk of suicide, which is closely tied to the distinctive attributes of the disorder, including biological factors, thymic decompensation, and psychological aspects. Consequently, managing their condition necessitates a tailored approach, demanding ongoing vigilance for individuals diagnosed with bipolar disorder.Disclosure of InterestNone Declared

IntroductionMedical students are a high-risk population for having suicidal thoughts and behaviors. However, few studies have been fulfilled on this subject.ObjectivesThe objective of this study was to provide a systematic overview of risk factors for suicidal ideations (SI) and suicide attempts (SA) among medical students.Methods
We set out to summarize the literature on the MEDLINE (via PUBMED) and Science Direct databases, regarding risk factors for SI and SA in medical students, using the key words : « medical student» ; « suicide attempt» ; « suicidal ideation », « risk ».Results
Recent studies showed that poor mental health outcomes including depression, anxiety, burnout, comorbid mental illness, and stress presented the strongest risk for SI among medical students. In addition, SI was statistically significantly associated with alcohol use, Tobacco consumption, personal history of suicide attempt, female gender and poor social support.On the other hand, SA were significantly associated with the presence of a long-term illness, anxiety and depression. Conversely, stress, female gender, and alcohol use were not significant risk factors for SA among medical students.ConclusionsMedical students face a number of personal, environmental, and academic challenges that may put them at risk for SI and SA. Additional research on individual risk factors is needed to construct effective suicide prevention programs in medical schools.Disclosure of InterestNone Declared

IntroductionSuicide is the most severe consequence of major depressive disorder (MDD). The most novel researches assume the role of immunological dysregulation in the background – several studies have reported alterations of inflammatory cells related to both MDD and suicidal behaviour (SB).ObjectivesChanges in the number of certain immune cells and their ratios have been proposed as potential biomarkers of suicide risk (SR). The aim of our research was to investigate alterations of these values related not only to MDD as an assumed inflammatory state, but also to an increased risk of SB.Methods
In our restrospective cohort study carried out between January 2015 and January 2020, we investigated laboratory parameters of psychiatric patients diagnosed with MDD (n=101). Individuals with recent (≤48 hours prior) suicide attempt (SA) (n=22) and with past SA (>48 hours prior) (n=19) represented the high SR group. MDD patients with no history of SA (n=60) composed the intermediate SR group. We compared the number of neutrophil granulocytes, monocytes, lymphocytes, platelets, leukocytes, neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), platelet-to-lymphocyte ratio (PLR), red blood cell distribution width (RDW) and erythrocyte sedimentation rate (ESR). Furthermore, we evaluated alterations of these parameters related to antidepressant (AD) treatment, which has been proved to have anti-inflammatory effects. Statistical analyses were carried out using GraphPad 9.5.0 and MedCalc 16.8 programmes.Results
We found a significant increase in neutrophil granulocyte count (p=0.016), NLR (p=0.031, Fig. 1), monocyte count (p≤0.0001), MLR (p=0.005, Fig. 2), leukocyte count (p=0.048) and ESR (p=0.037) in patients with recent SA compared to patients with no history of SA. Moreover, there was a significant elevation in monocyte count (p≤0.0001), MLR (p=0.020, Fig. 3), ESR (p=0.041) and RDW (p=0.037) in patients with high SR compared to patients with intermediate SR. AD treatment resulted in a significant decrease in neutrophil granulocyte count (p=0.0163) and NLR (p=0.016), however, it did not affect the rest of the parameters.Image:Image 2:Image 3:ConclusionsAssuming immunological mechanisms in the background of MDD and SB, our findings support the role of NLR as a biomarker of acute SR, though its alterations may be masked by AD therapy in the long term. However, MLR – remaining unaffected by AD treatment – may be a possible indicator of both acute and long term suicidal vulnerability. In order to further specify the diagnostic value of these parameters, future prospective research is needed.The study was supported by the FIKP-IV and the TNIL projects.Disclosure of InterestNone Declared
