Surace T, Buoli M, Affaticati LM, Esposito G, Capuzzi E, Colzani L, La Tegola D, Biagi E, Colmegna F, Caldiroli A, Clerici M. Which clinical factors delay proper treatment in panic disorder? A cross-sectional multicentric study. Early Interv Psychiatry 2024. [PMID: 38357849 DOI: 10.1111/eip.13506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 11/30/2023] [Accepted: 01/24/2024] [Indexed: 02/16/2024]
Abstract
AIM The aim of the present study was to identify clinical and socio-demographic factors associated with duration of untreated illness (DUI) in patients affected by panic disorder (PD). METHODS Data were collected from patients' medical records (N = 157) of two mental health services respectively located in Milan and in Monza (Italy). Correlation analyses and analysis of variance (ANOVAs) were run to analyse the relation between DUI and quantitative/qualitative variables respectively. Statistically significant variables in uni- variate analyses were then inserted in a linear multivariable regression model (backward procedure). RESULTS Mean DUI was 27.33 (±50.56) months. Patients with an earlier age at onset (r = -0.270; p < .01), a longer duration of illness (r = 0.483; p < .01) and who received a lifetime psychotherapy (F = 6.86; p = .01) had a longer DUI. The final global model showed that a longer DUI was associated with pre-onset poly-substance misuse (p = .05) and a longer duration of illness (p < .01). CONCLUSION The results of our study showed that a longer DUI was predicted by clinical factors such as the presence of a pre-onset poly-substance use disorder and that delayed proper treatment can lead to a chronicization of PD, as indicated by a longer duration of illness. Further studies are needed to in-depth investigate the role of DUI in influencing the course and outcome of anxiety disorders, including PD.

Barriers and facilitators for treatment-seeking in adults with a depressive or anxiety disorder in a Western-European health care setting: a qualitative study. BMC Psychiatry 2022; 22:165. [PMID: 35247997 PMCID: PMC8898419 DOI: 10.1186/s12888-022-03806-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Accepted: 02/17/2022] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND Previous research on barriers and facilitators regarding treatment-seeking of adults with depressive and anxiety disorders has been primarily conducted in the Anglosphere. This study aims to gain insight into treatment-seeking behaviour of adults with depressive and anxiety disorders in a European healthcare system. METHODS In-depth semi-structured interviews were conducted with 24 participants, aged ≥18 years and diagnosed with an anxiety disorder and/or depressive disorder according to DSM-IV. Participants were purposively sampled from an outpatient department for mental health care in the Netherlands. The seven steps of framework analysis were used to identify relevant themes emerging from the interviews. RESULTS Data analysis suggested an interplay between individual aspects, personal social system, healthcare system and sociocultural context influences. Amongst the most relevant themes were mental health illiteracy, stigma, a negative attitude toward professional help, the influence of significant others and general practitioner, and waiting time. Financial barriers were not of relevance. CONCLUSIONS Even in a country with a well-developed mental health care system and in absence of financial barriers, there are many barriers to treatment-seeking in adult patients with depressive and anxiety disorders. National campaigns to increase awareness and decrease stigma in the general population, and to empower the social environment might reduce the treatment gap.

The Relationship of Hypochondriasis to Anxiety, Depressive, and Somatoform Disorders. PSYCHOSOMATICS 2015; 57:200-7. [PMID: 26785798 DOI: 10.1016/j.psym.2015.10.006] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/20/2015] [Revised: 10/19/2015] [Accepted: 10/21/2015] [Indexed: 01/12/2023]
Abstract
BACKGROUND Though the phenotype of anxiety about medical illness has long been recognized, there continues to be debate as to whether it is a distinct psychiatric disorder and, if so, to which diagnostic category it belongs. OBJECTIVE Our objective was to investigate the pattern of psychiatric comorbidity in hypochondriasis (HC) and to assess the relationship of health anxiety to anxiety, depressive, and somatoform disorders. METHODS Data were collected as part of a clinical trial on treatment methods for HC. In all, 194 participants meeting criteria for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) HC were assessed by sociodemographic variables, results of structured diagnostic interviews, and validated instruments for assessing various symptom dimensions of psychopathology. RESULTS Most of the individuals with HC had comorbid psychiatric illness; the mean number of comorbid diagnoses was 1.4, and 35.1% had HC as their only diagnosis. Participants were more likely to have only comorbid anxiety disorders than only comorbid depressive or somatoform disorders. Multiple regression analysis of continuous measures of symptoms revealed the strongest correlation of health anxiety with anxiety symptoms, and a weaker correlation with somatoform symptoms; in multiple regression analysis, there was no correlation between health anxiety and depressive symptoms. CONCLUSION Our findings suggest that the entity of health anxiety (HC in DSM-IV and illness anxiety disorder in DSM-5) is a clinical syndrome distinct from other psychiatric disorders. Analysis of comorbidity patterns and continuous measures of symptoms suggest that its appropriate classification is with anxiety rather than somatoform or mood disorders.

Abstract
Internet-based cognitive behaviour therapy (ICBT) can be equally effective as traditional face-to-face cognitive behaviour therapy (CBT) for treating panic disorder (PD). However, little is known about the predictors and moderators of outcome of ICBT when delivered in psychiatric outpatient settings. This study investigated a selection of outcome predictors and moderators of ICBT for panic disorder based on data from a randomised controlled trial where therapist-guided ICBT was compared with group CBT (GCBT) for panic disorder. Participants (N = 104) received 10 weeks of ICBT or GCBT and were assessed before and after treatment, and after six months. Multiple regression analyses were used to test for significant predictors of treatment outcome. Predictors of positive treatment response for both modalities were having low levels of symptom severity and work impairment. In addition, anxiety sensitivity was found to have a small negative relationship with treatment outcome, suggesting that anxiety sensitivity may slightly enhance treatment response. Treatment modality had a moderating effect on the relationship between domestic impairment and outcome and on the relationship between initial age of onset of panic symptoms and treatment outcome, favouring ICBT for patients having had an early onset of PD symptoms and for patients having a high domestic functional impairment. These results suggest that both ICBT and GCBT are effective treatment modalities for PD and that it is possible to predict a significant proportion of the long-term outcome variance based on clinical variables.

Abstract
OBJECTIVE The aim was to investigate the association between panic disorder (PD) and long-term outcomes in terms of psychiatric morbidity, psychological distress and health-related quality of life (HRQOL), and to identify predictors of poor outcome for PD in chest pain patients. METHOD Nine-year follow-up study of chest pain patients (n=199) referred to cardiology outpatient investigation. Assessments included Structured Clinical Interview for DSM-IV, Symptom Checklist-90-R (SCL-90-R), Illness Attitude Scale, Agoraphobia Cognitions Questionnaire, the Mobility Inventory for Agoraphobia, Personality Diagnostic Questionnaire and the Medical Outcome Study Short Form-36. At baseline, 76 patients suffered from PD. RESULTS Of 184 eligible patients, 150 participated in the follow-up study. Panic disorder at baseline was associated with a higher prevalence of comorbid Axis I disorders, psychological distress and poorer HRQOL at follow-up compared with patients without PD. Of the participants with PD at baseline (n=55), 14 suffered from persistent PD at follow-up. Patients with persistent PD had particularly poor outcomes regarding comorbid Axis I disorders, suicidal ideation (21%) and HRQOL. A mean baseline SCL-90-R somatization score above 1.4 predicted a 5-fold increased risk of persistent PD. CONCLUSION Chest pain patients with PD have a negative long-term outcome and those who score high on somatization require special attention because of particularly poor outcomes.

Abstract
BACKGROUND Although the effectiveness of cognitive behavioural therapy (CBT) in the management of panic disorder (PD) is now well established, there have been few studies of predictors of outcome with this patient group using clinical effectiveness trial data, a hypothesis-testing model, and a dependent measure of clinically significant change. METHOD The data for this study came from a randomized controlled trial of three forms of CBT delivery for PD with and without agoraphobia (two 6-week CBT programmes, one of which was computer assisted, and one therapist-directed 12-week CBT programme), comprising a total of 186 patients across two sites. Based on previous related research, five hypothesized predictors of post-treatment and follow-up outcome were identified and examined, using a series of bivariate and multivariate analyses. RESULTS The results in general supported the hypotheses. Strength of blood/injury fears, age of initial onset of panic symptoms, co-morbid social anxieties and degree of agoraphobic avoidance were predictive of both measures of post-treatment outcome. Degree of residual social difficulties and the continued use of anxiolytics at post-treatment were also shown to predict poor outcome at the 6-month follow-up. However, strength of continuing dysfunctional agoraphobic cognitions by the end of active treatment did not predict outcome at follow-up for the sample as a whole. CONCLUSIONS The identification of consistent predictors of outcome with CBT has many clinical and research benefits. As CBT, however, is being delivered increasingly in a variety of brief formats, further research is required to identify moderators of response to these 'non-standard' treatment formats.

Abstract
BACKGROUND AND OBJECTIVE Dissociative experiences are widespread among patients with panic disorder and have a negative impact on cognitive-behavioural therapy. In this study we aimed to investigate whether or not dissociative experiences affect response to drug treatment for panic disorder. METHODS Thirty-five patients, 20 women and 15 men, with a mean age of 35.4 years and a diagnosis of panic disorder, were enrolled in the study. Paroxetine 20 mg/day was administered over 6 weeks. Patients were assessed on the Dissociative Experience Scale (DES) and Panic and Agoraphobia Scale (PAS) at the commencement of therapy, and on the PAS again after therapy. RESULTS The average DES score was determined as 30.3. Agoraphobia was identified in 34.3% of patients. DES scores were higher in patients with agoraphobia than in those without agoraphobia. Agoraphobia scores were higher in patients with high DES scores. When patients were divided into those with low DES scores (< or =30) and those with high DES scores (>30), a decrease in PAS scores with treatment was observed in both groups, but the decrease was greater in those with low DES scores (18.8 +/- 6.8 vs 5.7 +/- 5.7 in the high-DES score group; Z = 4.486, p = 0.00000053). Similarly, while a decrease in PAS scores with treatment was observed both in patients with agoraphobia (p < 0.05) and in those without agoraphobia, PAS scores decreased more in non-agoraphobic patients (16.7 +/- 7.5 vs 4.8 +/- 6.6 in patients with agoraphobia; Z = 3.799, p = 0.000047). In addition, the decrease in PAS scores was significantly correlated with baseline DES score (beta = 0.706, T = 5.727, p = 0.0000022). CONCLUSION This study shows that dissociative experiences reduce the response to drug therapy in patients with panic disorder.

Abstract
The present study was performed to compare the clinical features of patients with panic disorder with and without agoraphobia. The subjects were 233 outpatients with panic disorder (99 males and 134 females) diagnosed according to DSM-IV criteria. Sixty-three patients met the criteria for panic disorder without agoraphobia, and 170 met the criteria for panic disorder with agoraphobia. Patients with agoraphobia showed a significantly longer duration of panic disorder and higher prevalence of generalized anxiety disorder. However, there were no significant differences in prevalence of major depressive episodes, in current severity of panic attacks, or in gender ratio between the two groups. The second aim of the present study was to investigate the effects of onset age and sex differences on the development of agoraphobia within a half-year. The subjects were divided into two groups according to their self-report: patients who did or did not develop agoraphobia within 24 weeks of onset of panic disorder. A total of 40.6% of the patients developed agoraphobia within 24 weeks of the onset of panic disorder, and onset age and sex differences had no robust effect on the development of agoraphobia within 24 weeks.

Abstract
To investigate the functional abnormalities in the central nervous system (CNS) of patients with panic disorder (PD), we compared the electroencephalography (EEG) coherence values in 18 never-medicated PD patients with those in age-matched normal control subjects, and examined the relationships between EEG coherence values and both the duration of disease and the severity of panic attacks. EEG data were recorded in the resting state. The PD patients had lower coherence values with significant differences in F3-F4, C3-C4, P3-P4, F7-T5, and F8-T6. There were positive correlations for the higher alpha band between coherence values and both the duration of disease and the severity of panic attacks. These findings provide further evidence that PD patients have a lower degree of inter-hemispheric functional connectivity in the frontal region and intra-hemispheric functional connectivity in the bilateral temporal region, and that chronic condition or frequent panic attacks in PD patients may be related to the pathophysiological CNS changes.

Abstract
A substantial number of patients with panic disorder and agoraphobia may remain symptomatic after standard treatment (including selective serotonin reuptake inhibitors, tricyclic antidepressants, benzodiazepines, or irreversible monamine oxidase inhibitors). In this review, recommendations for the treatment of patients with panic disorder and agoraphobia who do not respond to these drugs are provided. Nonresponse to drug treatment could be defined as a failure to achieve a 50% reduction on a standard rating scale after a minimum of 6 weeks of treatment in adequate dose. When initial treatments have failed, the medication should be changed to other standard treatments. In further attempts at treatment, drugs should be used that have shown promising results in preliminary studies, such as venlafaxine. Combination treatments may be used, such as the combination of an selective serotonin reuptake inhibitor and a benzodiazepine. Psychological treatments such as cognitive-behavioral therapy have to be considered in all patients, regardless whether they are nonresponders or not. According to existing studies, a combination of pharmacologic treatment with cognitive-behavioral therapy can be recommended.

Abstract
Introdução/Objetivos: A hipocondria é associada a diversos transtornos de ansiedade, sobretudo ao transtorno de pânico (TP). Estima-se que 50% a 70% dos pacientes com TP tenham sintomas hipocondríacos, e que 13% a 17 % dos hipocondríacos tenham TP associado. O presente estudo teve como objetivo revisar a literatura sobre as relações clínicas, fenomenológicas, cognitivas e psicodinâmicas entre o TP e a hipocondria, além de discutir aspectos conceituais e critérios diagnósticos. Métodos: A busca de artigos foi feita pelo sistema Medline entre 1990 e 2001, utilizando-se, como palavras-chave, transtorno de pânico, agorafobia, hipocondria e preocupações hipocondríacas. Resultados: Considera-se que há comorbidade com hipocondria no TP quando as preocupações com saúde não se restringem a sintomas das crises de pânico. Apesar de geralmente consideradas secundárias, vários pacientes com TP apresentam, antes da primeira crise, manifestações hipocondríacas que podem ser consideradas prodrômicas. A ansiedade pode gerar, num círculo vicioso, preocupações excessivas com saúde, auto-observação seletiva e antecipação do pior. Apesar do viés catastrófico comum, no TP sintomas autonômicos aumentam rapidamente até culminar num ataque, a catástrofe temida é iminente, com comportamentos de esquiva e busca imediata de socorro. Na hipocondria, temem-se doenças mais insidiosas, predominam comportamentos de hipervigilância e busca de reafirmação, as crenças são mais disfuncionais, é pior a relação médico-paciente e maior o foco de sensações erroneamente interpretadas catastroficamente. O medo patológico da morte e a alexitimia estariam presentes nos dois quadros. Conclusão: A sobreposição clínica entre TP/agorafobia e hipocondria é relevante, mas não completa. A relação entre os dois quadros é complexa e possivelmente bidirecional, um aumentando a vulnerabilidade ao outro. Há diferenças fenomenológicas identificáveis e relevantes, com implicações diagnósticas e terapêuticas.

Abstract
Several effective pharmacotherapeutic treatments exist for panic disorder; however, not all patients respond to treatment: between 20% to 40% are non-responders. Recent studies have reported several predictors of nonresponse to pharmacotherapy. In this review two questions are addressed: is there consensus with respect to predictors of nonresponse and are there any differences between short-term and long-term predictors? In this review both short-term and long-term outcome studies are discussed. Studies were included if at least DSM-III criteria were used and baseline variables were investigated as possible predictor of response, or nonresponse, to pharmacotherapy. Of each clinical predictor, tallies were made of the particular predictors employed and of those predictors that predicted nonresponse. It appears that a long duration of illness and severe agoraphobic avoidance are robust predictors of nonresponse, particularly in long-term studies. Personality disorders, or even personality traits, are possibly the most robust predictors of nonresponse. Several factors appear to be robust predictors of nonresponse: factors that are present before treatment and exert their influence on short-term and long-term treatment outcome. Prospective studies are needed to further investigate these factors and to test whether it is viable to intervene in an attempt to increase treatment response.
