RESUMO

OBJECTIVES: Obsessive-compulsive disorder (OCD) has been connected to various psychosocial factors that might influence its onset and course. Developmental factors, such as parenting styles or early adverse experiences, and adult attachment have been listed as examples. However, the research on the interconnections of these factors brought mixed results. The study explores the relationship between demographic, clinical, and selected psychosocial factors and the severity of adult OCD. METHOD: Eighty-seven pharmacoresistant inpatients with OCD were admitted between October 2019 and August 2022 for a 6-week cognitive behavioural therapy inpatient program in the psychotherapeutic department. The participants completed the following scales at the start of the hospitalisation: the self-report Yale-Brown Obsessive-Compulsive Scale (Y-BOCS-SR), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI-II), Dissociative Experiences Scale (DES), Childhood Trauma Questionnaire-Short Form (CTQ-SF), PBI (Parental Bonding Instrument), ECR-R (Experiences in Close Relationships - Revised), and a demographic questionnaire. A skilled psychologist administered Mini International Neuropsychiatric Interview (MINI) to confirm the OCD diagnosis and Hamilton Anxiety Rating Scale (HAMA). RESULTS: OCD patients with more severe adverse childhood experiences (ACEs) showed earlier onset of the disorder and more pronounced attachment anxiety, depressive symptoms, and dissociation and subjectively rated the severity of the disorder as more severe. Physical abuse and physical neglect were related to the severity of specific OCD symptoms. Maternal care negatively correlates with clinician-rated anxiety, patient-rated depressive symptoms, and dissociation. The maternal and paternal control positively correlated with patient-rated anxiety and depression. Attachment anxiety negatively correlated with the age of onset and positively with the severity of the clinician-rated anxiety and the patient-rated anxiety, depressive symptoms, and dissociation. CONCLUSIONS: Early adverse experiences, perceived parental styles, and adult attachment anxiety could play a significant role in the symptoms of anxiety, depression, and dissociation. The connection with the specific obsessive-compulsive symptoms is less apparent. Still, adverse childhood events and adult attachment anxiety seem to influence the age of OCD onset.

RESUMO

OBJECTIVES: Obsessive-compulsive disorder (OCD) is a chronic mental disorder that is often hard to treat with current treatment options. Therapeutic outcomes are predicted by many factors, ranging from biological to psychosocial. Early life experiences and adult attachment influence the effectiveness of the treatment. This study explores their predictive abilities in the combined treatment of adult inpatients with OCD. METHODS: Seventy-seven patients with OCD, diagnosed according to the ICD-10 criteria, were included in the study, out of which 66 patients completed the treatment. All patients were previously unsuccessfully treated with a minimum of two antidepressants for three months each. They were evaluated with rating scales and questionnaires at the start and the end of a six-week hospitalization in a psychotherapeutic department. The treatment approach presented a combination of group cognitive-behavioural therapy and medication. RESULTS: The average severity of OCD, anxiety and depressive symptoms significantly decreased during the inpatient treatment. The improvement in Y-BOCS negatively correlated with the age of onset. The history of emotional abuse and neglect and physical neglect predicted a lower change in anxiety evaluated by a psychologist and perceived maternal care positively correlated with a decrease in anxiety assessed with a rating scale. Adult attachment anxiety predicted a lower decrease in the anxiety measured by the clinician but not the OCD symptomatology. Dissociative symptoms did not significantly predict a change in any of the measures. Comorbid personality disorder did not have a significant impact on therapeutic change. CONCLUSIONS: The early onset of the disorder was the sole predictor of the treatment outcomes regarding specific OCD symptomatology. Selected early adverse experiences, maternal care, and adult attachment anxiety predicted a change in the anxiety symptoms. Future research should focus on mediation and moderation analyses that could help target specific treatment strategies to decrease the impact of these factors.

RESUMO

OBJECTIVES: Self-stigma represents a process of accepting negative social prejudices with a consequent negative impact on many areas of the patient's life (self-concept, social and work functioning, relationships, cooperation in treatment, quality of life, willingness to strive for something). The study was aimed to examine the level of self-stigma and other significant variables potentially related to self-stigma (personality characteristics, childhood traumatisation, anxiety, depression, personality disorder, dissociation, parental styles, attachment). METHOD: The study was conducted at the Psychotherapeutic section of the Psychiatric Department in Regional Hospital Liberec from October 2015 to March 2019. A total of 96 hospitalised patients with neurotic spectrum disorders diagnosed by an experienced psychiatrist according to ICD-10 (panic disorder and/or agoraphobia, social phobia, generalised anxiety disorder, mixed anxiety depressive disorder, somatoform disorder, obsessive-compulsive disorder, adjustment disorders) were included into the study and filled in the test battery. RESULTS: The main finding is that self-stigma is related to the severity of the disorder, anxiety and depression, social anxiety, the comorbid occurrence of other anxiety disorders or personality disorders, dissociation, personality temperamental traits Harm Avoidance, Reward Dependence and Self-Directedness. We have not established a connection between attachment in close relationships and self-stigma. The most important predictors of self-stigma are the disorder's duration, reduced Self-Directedness, a higher rate of depression and social anxiety, which together explain 58% of severity if self-stigma. CONCLUSIONS: Self-stigma is a contemporary topic in research and clinical practice. The results can be used as a basis for the development of targeted intervention strategies aimed at reducing self-stigma or for further research studies in the field of self-stigma.

RESUMO

BACKGROUND: Panic disorder and agoraphobia not only affect the patients themselves but also may have a detrimental effect on their intimate relationships. A problem arising in the intimate sphere could be a trigger, a modulator, a maintenance factor, or the result of the panic disorder and agoraphobia. The consequences of panic disorder include increased demands on the non-affected partner to adapt, which may prove to be too challenging for some to manage. Panic disorder and agoraphobia can also change earlier relationship patterns which may result in partnership dysfunction. This review explores the effect of panic disorder and agoraphobia upon partnership problems and satisfaction. METHOD: Relevant studies were identified via PubMed and Web of Science, published between January 1970 and April 2020. The search terms included "panic disorder", "agoraphobia", "marital problems", "marital conflicts" and "marital adjustment". Further references were found in reviews, books, and book chapters of the relevant papers. A total of 1154 articles were nominated by primary assortment using the keywords in different combinations. After selecting according to the inclusion and exclusion criteria, evaluating the complete texts and searching for secondary documents, 173 papers were finally chosen. RESULTS: Problems in a relationship can act as a trigger for the development of the panic disorder and agoraphobia and could also function as modulating and maintenance factors. Panic disorder and agoraphobia often have a negative influence on the relationship and the non-affected partner. Partnership problems can be both a precursor and a consequence of panic disorder and agoraphobia.

RESUMO

OBJECTIVE: Obstructive sleep apnea (OSA) is a severe disorder with a high prevalence. Psychiatric comorbidities, especially depressive symptoms and cognitive dysfunction, are often described in OSA patients. This narrative review aims to examine: (1) the relationship between obstructive sleep apnea syndrome (OSAS) and depressive and cognitive symptoms, and (2) the effect of OSAS treatment on psychiatric symptoms. METHOD: Articles that were published between January 1990 and August 2018 were searched and extracted via PubMed, and Web of Science databases. Authors analyzed the papers and its references using the following keywords: obstructive sleep apnea, depression, cognitive dysfunction, anxiety disorders, and continuous positive airway pressure (CPAP). A total of 632 articles were nominated. After the selection according to the inclusion and exclusion criteria, 172 articles were chosen. After complete inspection of the full texts, finally, 58 papers were selected. Secondary papers from the reference lists of the primarily designated papers were also searched, assessed for suitability, and added to the first list of the papers (n = 67). In total, 125 papers were included in this review. RESULTS: There is a significant overlap in depressive, anxious and OSA symptoms. Studies also show that attention, working memory, episodic memory, and executive functions are decreased in OSA. Conversely, most of verbal functions remain intact and variable results are found in psychomotor speed. Several studies implicated that in some fields of cognitive functions (eg, attention) deficit caused by untreated OSA can be irreversible and shows only partial recovery after a period of treatment with CPAP. CONCLUSIONS: Untreated OSA impacts affective disorders, and often leads to decline of cognitive functions or even leads to permanent brain damage. Further studies are needed to analyze the connection between OSA and affective disorders, anxiety disorders and its effect on cognitive functions more thoroughly, especially in the context of CPAP treatment.

RESUMO

OBJECTIVES: In the new millennium, a growing focus on human rights and preserving individual autonomy urges the promotion of needs of the psychiatric patients. The topic of human needs takes its place also in patients with panic disorder. This review intended to explore current facts concerning the needs of the patients and present a broader understanding of patients' needs, due to the complexity of problems of patients with panic disorder. The text also focuses on psychosocial well-being and the quality of life of patients with panic disorder. METHODS: The PubMed was used to search for articles published between January 2000 and February 2020 using the following keywords: "panic disorder" or "agoraphobia" and "unmet needs" in combination with "pharmacotherapy" or "psychotherapy" or "cognitive behavioural therapy" or "family" or "quality of life." A total of 264 articles were selected by primary keyword picking in different combinations. Altogether 182 articles were reviewed. RESULTS: We identified the most important unmet needs of patients with panic disorder connected to symptoms, treatment and help-seeking, stigma and self-stigma, family and quality of life. To help the patients to improve the unmet needs connected with: (1) symptoms is to increase the awareness of treatment steps for patients and their families, good cooperation with therapists, and management of persistent symptoms, alleviation or elimination of anxiety symptoms, avoidance and safety behaviour. (2) treatment is the quick approach, effective one, not too difficult, without side effects and harmless, not requiring hospitalization and not disturbing the daily routine, increasing treatment compliance, improving patient self-confidence and an active social network, affordable health and social services and more suitable information for families; (3) stigma is to change of public opinion about people with mental health problems and to create effective antistigma programs; (4) family is to include the support for a functional and independent life, helping to manage everyday tasks and stop excessive protection, while reducing the stigmatization of the whole family. (5) the quality of life is to help to integrate into the community and improve the factors that affect the quality of life; like esteem, self-acceptance, social acceptance etc. CONCLUSIONS: This review aimed to explore the unmet needs in patients with panic disorder or agoraphobia. In selected articles we identified 5 basic unmet needs and described the basic strategies to cope with them. It is essential for every clinician to understand those needs as it can substantially help to alleviate patients' symptoms and improve their quality of life. The importance of this understanding further highlights that unmet needs described for panic disorder overlap with unmet needs of other psychiatric disorder and thus have broader utility.

RESUMO

OBJECTIVES: A combination of antidepressants with the cognitive-behavioural therapy showed effectiveness in treatment-resistant patients with panic disorder. This prospective study intended to establish how childhood adverse experiences, self-stigma, dissociation, and severity of psychopathology influence the effectiveness of combined cognitive-behavioural therapy and pharmacotherapy in patients with treatment-resistant panic disorder. METHODS: One hundred and ten patients were included into the study and one hundred five subjects finished the study. After admission, the subjects were assessed during the first two days of hospitalization. Rating scales were administered before the beginning of the cognitive behavioural therapy (measurement-1) and at the end of the treatment which was after six weeks (measurement-2). Patients with panic disorder were treated using a combination of group cognitive-behavioural therapy and antidepressants. The usual antidepressant dosage range was used. Before admission to intensive cognitive behavioural therapy program, the patients were unsuccessfully treated by antidepressants for minimum 3 months, which defined them as pharmacoresistant. RESULTS: Hospitalized pharmacoresistant patients with panic disorder improved significantly throughout the 6-week intensive CBT program in all measurements that assessed the overall severity of the disorder, the degree of general anxiety and depression and the severity of specific symptoms of panic disorder and agoraphobia. The rate of improvement was negatively related to sexual abuse in childhood, presence of comorbid personality disorder, and positively with the severity of the disorder at the beginning, and the level of self-stigma at the beginning of treatment. Improvement in symptoms correlates significantly with decreasing of dissociation during the treatment.severity of depressive symptoms. The earlier development of the disorder is linked to higher score in childhood adverse events, higher level of dissociation and pathological dissociation, and higher level of self-stigma. CONCLUSIONS: Our prospective study discovers importance of the role of adverse childhood experiences, self-stigma, dissociation and comorbid personality disorder in effectiveness of combined cognitive-behavioural therapy and pharmacotherapy treatment in patients with treatment-resistant panic disorder.

RESUMO

OBJECTIVES: Little is known about the relation between severity of panic disorder, adverse events in childhood, dissociation, self-stigma and comorbid personality disorders. The aim of this study is to look for the intercorrelations between these factors. METHOD: The study explores the relation between clinical, demographic and social factors in panic disorder using cross sectional design. The inpatients with pharmacoresistant panic disorder with and without agoraphobia were included in the study. Participants were also assessed for comorbidity with other anxiety or personality disorder. The Clinical Global Impression (CGI), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI-II), Dissociative Experiences Scale (DES), Internalized Stigma of Mental Illness (ISMI), Childhood Trauma Questionnaire-Short Form (CTQ-SF), Panic Disorder Severity Scale (PDSS) and demographic data were used as measurement tools. RESULTS: A total of 142 pharmacoresistant patients with panic disorder with or without agoraphobia were admitted for 6-week cognitive behavioral therapy inpatient program in psychotherapeutic department between November 2015 and July 2019. One hundred and five inpatients (33 males and 72 females) with mean age 37.8 + 12.1 years were included in the study. Sixty-nine patients suffer from additional comorbid anxiety disorder and 43 had comorbid personality disorder.

RESUMO

BACKGROUND: Much attention has been paid to psychological factors influencing characteristics, severity, and course of mental disorders. The objective of our investigation was to examine the interrelations among quality of life (QoL), self-stigma, and coping strategies, demographics and severity of the disorder in neurotic spectrum disorders, schizophrenia, and depressive spectrum disorders. METHODS: A total of 343 clinically stable Czech outpatients with different mental disorders (153 with neurotic spectrum disorders; 81 with depression, and 109 with schizophrenia spectrum disorders) were included. The patients were examined by their outpatient psychiatrists during regular psychiatric checkup and completed a sociodemographic questionnaire, the Quality of Life Satisfaction and the Enjoyment Questionnaire (Q-LES-Q), the Internalized Stigma of Mental Illness Scale (ISMI), the Stress Coping Style Questionnaire (SVF-78), and the Clinical Global Impression scale (CGI). RESULTS: The study demonstrates that the self-stigma and coping strategies are significant factors linked to the QoL in all diagnostic groups of patients. Patients with schizophrenia spectrum disorders had lower scores in QoL compared to the other two groups. The patients with depression or neurotic spectrum disorders had a lesser degree of self-stigma than the patients with schizophrenia spectrum disorders. The severity of the illness significantly correlated with the QoL, self-stigma, and coping strategies. CONCLUSIONS: The investigation confirmed the connection between the quality of life, self-stigma, coping strategies, and the severity of the illness, in outpatients with schizophrenia spectrum disorders, depressive, and neurotic spectrum disorders. A further longitudinal study would be useful to determine the causative relationships of these variables.

RESUMO

BACKGROUND AND AIM: Patients who have schizophrenia are more prone to suicidal behavior than the general population. This study aimed to find connections between suicidality and self-stigma, hope, and personality traits in patients with schizophrenia. METHODS: Forty-eight stabilized outpatients with schizophrenia attended this cross-sectional study. Patients were diagnosed by the Mini International Neuropsychiatric Interview (MINI) using the ICD-10 research diagnostic criteria. The assessments included Positive and Negative Syndrome Scale, objective and subjective Clinical Global Impression, Liebowitz Social Anxiety Scale, Beck Depression Inventory-second edition, Internalized Stigma of Mental Illness, the Temperament and Character Inventory, and Adult Dispositional Hope Scale. RESULTS: The individual rate of suicidality (suicidal index from MINI) strongly positively correlated with self-stigma, level of depression, social anxiety, and harm-avoidance, and negatively correlated with hope, self-directedness, and stigma resistance. CONCLUSION: Individuals with additional symptoms of depression, social anxiety, trait-like anxiety, and self-stigma should be carefully monitored for suicidal ideation. On the opposite side, patients with sufficient hope, self-esteem, and goal-directed attitudes are less likely to have suicidal thoughts and may potentially be role models in group rehabilitation programs, motivating more distressed colleagues and showing them ways to cope.

RESUMO

BACKGROUND: The aim of this study was to assess the pediatric population that suffered from inflammatory bowel disease (IBD) in the Czech Republic and to determine the incidence of Crohn disease (CD) in children up to 15 years age between 1990 and 2001. METHODS: Diagnostic criteria for CD, ulcerative colitis (UC), and indeterminate colitis (IC) were defined. Medical records provided a source of basic information about the children. A standardized protocol was filled out and sent to the coordinator of the study. All protocols were checked to see whether the data corresponded to the defined criteria and then were processed further. The study was retrospective in character for the years 1990 to 1999 and prospective for the years 2000 and 2001. RESULTS: Diagnostic criteria were met in 470 patients with IBD; 201 of them turned 18 years old during the study period. CD was diagnosed in 223 patients. The incidence of CD in children up to 15 years of age increased from 0.25/100,000 in 1990 to 1.25/100,000 in 2001. Eighty-two percent of children with CD were treated with aminosalicylates in combination with corticosteroids; 29% of patients received azathioprine. Severe growth retardation was recorded in 6.4% of adolescents with CD at the age of 18. UC was diagnosed in 202 patients. Therapy with aminosalicylates only was sufficient for control of the disease in 23% patients; 68% children were treated with corticosteroids, 15 of them (23% of the whole group) received additional azathioprine. Criteria for IC were met in 9.8% of all patients with IBD. CONCLUSION: This study confirmed an increase in incidence of CD in children younger than 15 years in the Czech Republic.

RESUMO

Mechanisms leading to morphological changes of the small intestine during coeliac disease (CD) are not yet completely recognized; however, two main processes have been suggested recently: remodeling of mucosa by matrix metalloproteinases, and mucosal atrophy by apoptosis. The aim of this study was analysis of the expression of proteins regulating apoptosis in the small intestine of children with active CD (ACD) and potential CD (PCD). Jejunal biopsies of 43 children with PCD and untreated ACD and 21 control samples were analyzed by means of standard indirect immunohistochemical technique for Fas, Fas ligand (Fas-L), tissue transglutaminase (tTG), Bcl-2, and glutathione S-transferase (GST) expression. We found significantly lower numbers of Fas-expressing enterocytes in the ACD patients than in PCD patients and controls. Similarly, the number of Fas-positive mucosal lymphocytes was decreased in ACD when compared with PCD. The number of Fas-L- and tTG-expressing enterocytes and mucosal lymphocytes was higher in both PCD and ACD. On the other hand, the number of Bcl-2-positive mucosal lymphocytes in PCD as well as ACD was significantly lower. The expression of tTG in extracellular matrix was significantly higher in PCD and ACD when compared with controls. Our results showed that Fas and/or Fas-L, Bcl-2, and tTG may be involved in apoptotic pathways leading to mucosal atrophy in children with CD. tTG changes are in agreement with the presumed role of this protein in the pathogenesis of CD.
