RESUMO

BACKGROUND: Panic disorder (PD) is a common disabling condition characterized by recurrent panic attacks. Emotional and behavioral impairments are associated with functional connectivity (FC) and network abnormalities. We used the whole brain FC, modular networks, and graph-theory analysis to investigate extensive network profiles in PD. METHOD: The functional MRI data from 82 PD and 97 controls were included. Intrinsic FC between each pair of 160 regions, 6 intra-networks, and 15 inter-networks were analyzed. The topological properties were explored. RESULTS: PD patients showed altered FCs within the right insula, between frontal cortex-posterior cingulate cortex (PCC), frontal cortex-cerebellum, and PCC-occipital cortex (corrected P values < 0.001). Lower connections within the Sensorimotor Network (SMN) and SMN-Occipital Network (OCN) were detected (P values < 0.05). Various decreased global and local network features were found in PD (P values < 0.05). In addition, significant correlations were found between PD symptoms and nodal efficiency (Ne) in the insula (r = -0.273, P = 0.016), and the FC of the intra-insula (r = -0.226, P = 0.041). CONCLUSIONS: PD patients present with abnormal functional brain networks, especially the decreased FC and Ne within insula, suggesting that dysfunction of information integration plays an important role in PD.

RESUMO

Abstract Avoidant or Restrictive Food Intake Disorder (ARFID) is an eating disorder (ED) not common in adults. In this article we present a clinical case of ARFID in a 37-year-old male patient treated in an ED center in Medellin, Colombia; displaying anxious symptoms that began a year earlier and concomitant weight loss, following a traumatic event causing an overall impairment with that patient. Several medical evaluations/examinations looking for organic causes, were excluded. Interventions were implemented by a psychiatry, a psychotherapist using cognitive-behavior therapy (CBT), and a nutritionist, all in face-to-face modality, which were carried out weekly for the first three months, then biweekly and subsequently quarterly. each lasting approximately 40-60 minutes. After the set of pharmacological interventions and psychotherapy, a great improvement in the functionality of the patient was observed. Improvement was found with respect to eating in public, food variation and panic attacks. In the absence of guidelines, it is important to use standardized and replicable treatments in this population.


Resumen El trastorno evitativo restrictivo de la ingesta (TERIA) es un trastorno alimentario (TCA) raro en adultos. Se presenta el caso de un hombre de 37 años con TERIA y trastorno de pánico atendido en un centro para TCA en Medellín, Colombia, quien presentó un año de síntomas ansiosos y pérdida de peso después de evento traumático, generando disfuncionalidad. Fue evaluada y excluida organicidad. Se realizaron intervenciones por parte de psiquiatría, psicoterapia con enfoque cognitivo conductual y nutrición, todas en modalidad presencial, las cuales se realizaron semanalmente los primeros tres meses, luego quincenalmente y posteriormente trimestralmente. Cada una con una duración de 40-60 minutos aproximadamente por sesión. Posterior al conjunto de intervenciones farmacológicas y psicoterapia, se observó una gran mejoría la funcionalidad del paciente, se encontró mejoría con respecto a comer en público, variación en los alimentos y ataques de panico. Ante la ausencia de guías de manejo de TERIA en adultos es relevante realizar tratamientos estandarizados que puedan ser replicados.

RESUMO

Objective: To develop a classification framework based on random forest (RF) modeling to outline the declarative memory profile of patients with panic disorder (PD) compared to a healthy control sample. Methods: We developed RF models to classify the declarative memory profile of PD patients in comparison to a healthy control sample using the Rey Auditory Verbal Learning Test (RAVLT). For this study, a total of 299 patients with PD living in the city of Rio de Janeiro (70.9% females, age 39.9 ± 7.3 years old) were recruited through clinician referrals or self/family referrals. Results: Our RF models successfully predicted declarative memory profiles in patients with PD based on RAVLT scores (lowest area under the curve [AUC] of 0.979, for classification; highest root mean squared percentage [RMSPE] of 17.2%, for regression) using relatively bias-free clinical data, such as sex, age, and body mass index (BMI). Conclusions: Our findings also suggested that BMI, used as a proxy for diet and exercises habits, plays an important role in declarative memory. Our framework can be extended and used as a prospective tool to classify and examine associations between clinical features and declarative memory in PD patients.

RESUMO

We investigated the level of hearing tolerance in patients with first-episode psychosis (FEP) and panic disorder (PD) as compared to two different groups of healthy controls (HC, HC2), one for each experiment, because we used two distinct psychophysical paradigms. We evaluated auditory discomfort of 28 volunteers (14 with FEP and 14 HC) in the first study and of 42 volunteers (21 with PD and 21 HC2) in the second study. We presented 20 sounds: 16 pure-tone frequency sweeps (specially designed for use with FEP) and 11 s or 13 s musical sequences from the very beginning of the music "Play the Game" (PLAY) from Queen and its reverses. The first procedure used a Likert-like 0-10 scale ranging from "nothing bad" to "too bad" where volunteers made vertical marks along a horizontal line according to their discomfort. The second procedure involved subjective magnitude estimation online due to the SARS-COV-19 pandemic. Sounds were placed online and played by PD and HC2 volunteers themselves after having listened to the standard (the first 8 s from RADIO, "Radio Ga Ga" by Queen). Then, PD and HC2 volunteers were asked to assign values equal to, or multiples of 10 that felt like, or proportional to, their hearing "discomfort" in comparison with Sound 00 (RADIO). Our findings showed that FEP volunteers assign more discomfort to the 16 specially designed frequency sweep stimuli that appear not to affect HC, HC2, and PD. On the other hand, musical sequences from PLAY caused strong discomfort to PD in the reverse mode, but did not seem to affect HC, HC2, and FEP. Further experiments using the exact same paradigm with FEP and PD are needed to explore these findings.

RESUMO

ABSTRACT. Panic disorder is an anxiety condition characterized by recurrent and unexpected panic attacks. The comparison between active treatment and placebo is essential to analyze an intervention's efficacy and safety. It is important to identify and summarize the studies with higher evidence to assist health professionals and public policy managers in clinical decision-making. Objective: The aim of this study was to identify and summarize all Cochrane systematic reviews (SRs) that compared the efficacy and safety of any drug treatment compared to placebo for panic disorder patients. Methods: SRs published in the Cochrane Library were included without date restriction. All outcomes presented were analyzed. The methodological quality of the SRs was evaluated using the AMSTAR-2 tool. Results: We included three Cochrane SRs of high methodological quality on the effects of antidepressants, benzodiazepines, and azapirones for panic disorder. All medications showed benefits in response to treatment, symptom improvement, and reduced panic attacks. Dropouts were lower with tricyclic antidepressants and benzodiazepines and higher with azapirones. The occurrence of adverse events was higher for drug groups. Conclusions: Very low to moderate certainty evidence (GRADE) showed that antidepressants and benzodiazepines seem to improve clinical symptoms in individuals with short-term panic disorder compared to placebo. In addition, the use of azapirones seems to have greater adherence by patients than placebo. However, there is insufficient evidence to support its clinical efficacy.


RESUMO. O transtorno de pânico é uma condição de ansiedade caracterizada por ataques de pânico recorrentes e inesperados. A comparação entre tratamento ativo e placebo é essencial para analisar a eficácia e a segurança de uma intervenção. É importante identificar os estudos com maiores evidências para auxiliar os profissionais de saúde e gestores de políticas públicas nas decisões clínicas. Objetivo: Identificar e sumarizar todas as revisões sistemáticas (RS) publicadas na Cochrane que relatam a eficácia e a segurança de qualquer tratamento medicamentoso comparado ao placebo para pacientes com transtorno de pânico. Métodos: Foram selecionadas e analisadas todas as RS publicadas na base de dados Cochrane, sem restrição de data. A qualidade metodológica das RS foi avaliada utilizando a ferramenta AMSTAR-2. Resultados: Foram incluídas três RS Cochrane com alta qualidade metodológica que avaliaram os efeitos de antidepressivos, benzodiazepínicos e azapironas para transtorno de pânico. Todos os medicamentos mostraram benefícios na resposta ao tratamento, melhora dos sintomas e redução das crises de pânico. O número de desistências do tratamento foi baixo com antidepressivos tricíclicos e benzodiazepínicos e alto com azapironas. A ocorrência de eventos adversos foi elevada para os grupos das medicações analisadas Conclusões: Evidências de certeza muito baixa a moderada (pela Classificação de Recomendações, Avaliação, Desenvolvimento e Análises - GRADE) mostraram que antidepressivos e benzodiazepínicos parecem melhorar os sintomas clínicos em indivíduos com transtorno de pânico em menor prazo, em comparação ao placebo. Além disso, o uso de azapironas parece ter maior adesão por parte dos pacientes do que o placebo. No entanto, não há evidências suficientes para comprovar sua eficácia clínica.

RESUMO

INTRODUCTION: In the last few decades, exercise has been explored as a potential tool to reduce symptoms experienced by patients with panic disorder (PD). This systematic review aims to assess the effects of regular exercise interventions on panic severity, global anxiety, and depression symptoms of these patients. AREAS COVERED: A search was conducted on PubMed, ISI Web of Science, and Cochrane Central Register of Controlled Trials using search terms related to PD and exercise. Eight trials were included, Furthermore, regular exercise programs presented different methodological characteristics. There is o clear evidence indicating that regular exercise programs (at least two 20-minute sessions per week for at least 6 weeks) reduce panic-related symptoms. Regular exercise is effective in improving global anxiety measures and depression. EXPERT OPINION: Continuous aerobic exercise is the main type of intervention in the literature, generally providing a limited prescription. Currently, it is recommended the interval training, with intense and shorter stimuli, and long-term duration trials. However, despite the use of self-selected intensities and control based on the internal load be interesting as recommendation to increase adherence, careful is needed regarding training prescription due to scarce evidence.

RESUMO

The antidepressant effect of ketamine has been widely acknowledged and the use of one of its enantiomers, S-ketamine (esketamine), has recently been approved for the clinical management of treatment-resistant depression. As with ketamine, the non-selective opioid receptor-interacting drug buprenorphine is reported to have antidepressant and anxiolytic properties in humans and rodents. Given the fact that antidepressant drugs are also first line treatment for panic disorder, it is surprising that the potential panicolytic effect of these compounds has been scarcely (ketamine), or not yet (buprenorphine) investigated. We here evaluated the effects of ketamine (the racemic mixture), esketamine, and buprenorphine in male Wistar rats submitted to a panicogenic challenge: acute exposure to hypoxia (7% O2). We observed that esketamine (20 mg/kg), but not ketamine, decreased the number of escape attempts made during hypoxia, and this effect could be observed even 7 days after the drug administration. A panicolytic-like effect was also observed with MK801, which like esketamine, antagonizes NMDA glutamate receptors. Buprenorphine (0.3 mg/kg) also impaired hypoxia-induced escape, an effect blocked by the non-selective opioid receptor antagonist naloxone, indicating an interaction with classical ligand sites, such as µ and kappa receptors, but not with nociception/orphanin FQ receptors. Altogether, the results suggest that esketamine and buprenorphine cause rapid-onset panicolytic-like effects, and may be alternatives for treating panic disorder, particularly in patients who are refractory to standard pharmacological treatment.

RESUMO

Objective: To investigate the course of panic disorder and its demographic and clinical correlates during the postpartum period. Methods: Data were collected from 38 consecutive postpartum women diagnosed with panic disorder. Psychiatric assessments were carried out on the first day after delivery and at 6-8 weeks postpartum. During the first assessment, the Panic and Agoraphobia Scale (PAS), Hospital Anxiety and Depression Scale (HADS), Coping Orientation to Problems Experienced (COPE), Multidimensional Scale of Perceived Social Support (MSPSS), and Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) were administered to the participants. PAS was also administered at the second assessment. Results: The mean PAS score reduced significantly from baseline to the second assessment. Logistic regression analysis indicated that a shorter duration of panic disorder independently predicted a ≥ 50-point decrease in the severity of panic symptoms during the postpartum period. Conclusion: These findings suggest that patients with a short duration of illness may experience significant alleviation in the severity of panic symptoms during the postpartum period.

RESUMO

Panic disorder (PD) pathophysiology is very heterogeneous, and the discrimination of distinct subtypes could be very useful. A subtype based on respiratory symptoms is known to constitute a specific subgroup. However, evidence to support the respiratory subtype (RS) as a distinct subgroup of PD with a well-defined phenotype remains controversial. Studies have focused on characterization of the RS based on symptoms and response to CO2. In this line, we described clinical and biological aspects focused on symptomatology and CO2 challenge tests in PD RS. The main symptoms that characterize RS are dyspnea (shortness of breath) and a choking sensation. Moreover, patients with the RS tended to be more responsive to CO2 challenge tests, which triggered more panic attacks in this subgroup. Future studies should focus on discriminating respiratory-related clusters and exploring psychophysiological and neuroimaging outcomes in order to provide robust evidence to confirm RS as a distinct subtype of PD.

RESUMO

OBJECTIVES: This paper introduces a new diagnostically oriented screening scale for anxiety disorders, the Center for Epidemiologic Studies Anxiety scale (CESA), designed in parallel to the revised Center for Epidemiologic Studies Depression scale (CESD-R). In this study, the CESA was used as a diagnostic screening tool for detecting the presence of anxiety disorder symptomatology ascertained by a clinical psychiatric evaluation based on the DSM-5 criteria. The CESA is designed to provide an overall evaluation of anxiety as well as to screen for four important anxiety disorders (agoraphobia, social phobia, blood-illness phobia, and panic disorder). METHODS: The test sample was composed of 80 adults seeking treatment for mental problems in a general psychiatric clinic. We assessed the receiver operating characteristic (ROC) curve of the CESA in comparison to the psychiatric interview. RESULTS: The main findings suggest that the CESA is useful for screening for anxiety in general (alpha coefficient of 0.83), as well as for the four common anxiety disorders. The criterion validation confirmed a high level of compatibility between the CESA and the psychiatric evaluation. CONCLUSION: This is the initial report regarding the CESA and future research will focus on specific aspects of criterion validity for each disorder.

RESUMO

Many pharmacological treatments were proved effective in the treatment of panic disorder (PD), generalized anxiety disorder (GAD), social anxiety disorder (SAD), post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD); still many patients do not achieve remission with these treatments. Neurostimulation techniques have been studied as promising alternatives or augmentation treatments to pharmacological and psychological therapies. The most studied neurostimulation method for anxiety disorders, PTSD, and OCD was repetitive transcranial magnetic stimulation (rTMS). This neurostimulation technique had the highest level of evidence for GAD. There were also randomized sham-controlled trials indicating that rTMS may be effective in the treatment of PTSD and OCD, but there were conflicting findings regarding these two disorders. There is indication that rTMS may be effective in the treatment of panic disorder, but the level of evidence is low. Deep brain stimulation (DBS) was most studied for treatment of OCD, but the randomized sham-controlled trials had mixed findings. Preliminary findings indicate that DBS could be affective for PTSD. There is weak evidence indicating that electroconvulsive therapy, transcranial direct current stimulation, vagus nerve stimulation, and trigeminal nerve stimulation could be effective in the treatment of anxiety disorders, PTSD, and OCD. Regarding these disorders, there is no support in the current literature for the use of neurostimulation in clinical practice. Large high-quality studies are warranted.

RESUMO

BACKGROUND: Antidepressants are the first-choice for pharmacological treatment of panic disorder. However, they present disadvantages, such as delayed therapeutic effect, many side effects and a considerable rate of non-responders. These shortcomings prompt the development of new therapeutic strategies. Among these are the adjunctive use of enkephalinase inhibitors, such as opiorphin, which supposedly acts by increasing the availability of brain enkephalins and other endogenous opioids. AIMS: We here evaluated whether opiorphin in the dorsal periaqueductal grey matter (dPAG), a key panic-related area, accelerates and/or facilitates the antipanic-like effect of fluoxetine or imipramine. We also verified whether the panicolytic effect of imipramine depends on activation of µ-opioid receptors (MORs). METHODS: Male Wistar rats were submitted to the escape task of the elevated T-maze, an index of panic attack, after treatment with imipramine (3, 7 or 21 days) or fluoxetine (3, 7, 14 or 21 days), combined with an intra-dPAG injection of opiorphin. RESULTS: Opiorphin facilitated and accelerated the panicolytic-like effect caused by imipramine, but not with fluoxetine. The antipanic-like effect caused by chronic imipramine did not depend on MOR activation in the dPAG. CONCLUSION: Combined treatment of antidepressant drugs with opiorphin for hastening or potentiating the effects of the former compounds may not be generally effective, with the results varying depending on the type/class of these panicolytic drugs.

RESUMO

BACKGROUND: Acute administration of caffeine produces panic attacks in most Panic Disorder (PD) patients, but little is known about chronic caffeine use in these patients. OBJECTIVE: To assess caffeine use in patients with PD and to ascertain if caffeine consumption is associated with sociodemographic or clinical features. METHODS: 65 adults with PD and 66 healthy controls were included in the current study. Their caffeine intake within the previous week was quantified with a questionnaire and compared. Harmful caffeine use was defined as consumption above 400 mg/day of caffeine. We tested for correlations between caffeine intake, demographic and clinical features. RESULTS: Patients consumed significantly more caffeine than controls (P < 0.001). 14% (N = 9) of the PD patients made harmful use of caffeine. The use of caffeine-containing medications was observed in 40% (N = 26) of the PD patients and 6% (N = 4) of controls. Consumption of energy drinks was observed in 11% (N = 7) of PD patients and in none of the healthy subjects. Patients reported sleeping significantly less than controls (P < 0.001). In PD patients, caffeine consumption was not correlated with the presence of panic attacks or comorbidity with depression. The use of benzodiazepines or sedative medications was not correlated with caffeine intake. CONCLUSION: High caffeine consumption in PD patients could be explained by the development of tolerance with regular use of this substance. Subtypes of sensitive and non-sensitive PD patients could also explain why some of these patients are able to tolerate high doses of caffeine.

RESUMO

Abstract Objective To identify which clinical features and personality traits are associated with quality of life (QoL) in panic disorder (PD) patients. Methods This was a cross-sectional study with PD patients. The brief version of the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF) and the Big Five Inventory (BFI) were used to assess QoL and personality traits respectively. The strength of correlations was measured with Pearson's, Spearman's, and point-biserial correlation coefficients. We also performed multiple linear regressions, considering sociodemographic data and scores from clinical scales as independent variables and QoL scores as dependent variables. Results A total of 98 patients were evaluated. Depressive symptoms had a strong negative correlation with QoL and, to a lesser extent, panic and anxiety symptoms were also negatively correlated with QoL. While consciousness, extraversion, and agreeableness had mild positive correlations with QoL, neuroticism had a strong negative correlation. Conclusion Symptoms of depression, anxiety, and panic seem to have a negative impact on the QoL of PD patients. Personality traits, especially neuroticism, may also influence QoL in these patients.


Resumo Objetivo Identificar quais características clínicas e traços de personalidade são mais associados à qualidade de vida (QdV) em pacientes com transtorno de pânico (TP). Métodos Este foi um estudo transversal, realizado em pacientes com TP. A versão breve do Questionário de Qualidade de Vida da Associação Mundial de Saúde (World Health Organization Quality of Life Questionnaire - WHOQOL-BREF) e o Inventário dos Cinco Grande Fatores (Big Five Inventory - BFI) foram utilizados para avaliar QdV e traços de personalidade, respectivamente. A força de associação foi medida através da correlação de Pearson, de Spearman ou ponto bisserial. Foram também realizadas regressões lineares múltiplas, considerando os dados sociodemográficos e escores obtidos nas escalas clínicas como variáveis independentes, e os escores de QdV como variáveis dependentes. Resultados Um total de 98 pacientes foram avaliados. Sintomas depressivos apresentaram uma forte relação negativa com QdV; em menor intensidade, sintomas de TP e ansiosos também se correlacionaram com QdV. Nos domínios de personalidade, enquanto conscienciosidade, extroversão e amabilidade apresentaram uma leve correlação positiva com QdV, neuroticismo apresentou forte correlação negativa. Conclusão Sintomas depressivos, ansiosos e de TP parecem ter forte impacto negativo na QdV dos pacientes com TP. Traços de personalidade, principalmente neuroticismo, podem influenciar QdV nesses pacientes.

RESUMO

BACKGROUND: A growing number of studies are questioning the validity of current DSM diagnoses, either as "discrete" or distinct mental disorders and/or as phenotypically homogeneous syndromes. In this study, we investigated how symptom domains in patients with a main diagnosis of obsessive-compulsive disorder (OCD), panic disorder (PD) and social anxiety disorder (SAD) coaggregate. We predicted that symptom domains would be unrelated to DSM diagnostic categories and less likely to cluster with each other as severity increases. METHODS: One-hundred eight treatment seeking patients with a main diagnosis of OCD, SAD or PD were assessed with the Dimensional Obsessive-Compulsive Scale (DOCS), the Social Phobia Inventory (SPIN), the Panic and Agoraphobia Scale (PAS), the Anxiety Sensitivity Index-Revised (ASI-R), and the Beck Depression and Anxiety Inventories (BDI and BAI, respectively). Subscores generated by each scale (herein termed "symptom domains") were used to categorize individuals into mild, moderate and severe subgroups through K-means clusterization and subsequently analysed by means of multiple correspondence analysis. RESULTS: Broadly, we observed that symptom domains of OCD, SAD or PD tend to cluster on the basis of their severities rather than their DSM diagnostic labels. In particular, symptom domains and disorders were grouped into (1) a single mild "neurotic" syndrome characterized by multiple, closely related and co-occurring mild symptom domains; (2) two moderate (complicated and uncomplicated) "neurotic" syndromes (the former associated with panic disorder); and (3) severe but dispersed "neurotic" symptom domains. CONCLUSION: Our findings suggest that symptoms domains of treatment seeking patients with OCD and anxiety disorders tend to be better conceptualized in terms of severity rather than rigid diagnostic boundaries.

RESUMO

BACKGROUND: Although resilience and coping are important factors associated with mental health, they are rarely investigated in the treatment of patients with panic disorder (PD). OBJECTIVE: To evaluate the response to four resilience and coping strategy sessions added to the standard cognitive behavioral group therapy (CBGT) protocol for PD. DESIGN: Controlled clinical trial. METHODS: The control group (n = 50) attended 12 CBGT sessions, while the intervention group (n = 50) received four additional resilience and coping strategy sessions, i.e., 16 in total. Symptom severity, resilience, coping strategies, and quality of life were assessed at baseline and post-CBGT. RESULTS: Symptom severity and maladaptive coping strategies decreased significantly in both groups. However, the intervention group had increased resilience and improvement in the environment domain of quality of life. CONCLUSIONS: Additional sessions have potential benefits for coping skills and resilience in PD patients, but these benefits should be evaluated in further long-term studies.

RESUMO

OBJECTIVE: Treatment for panic disorder (PD) have evolved, although there is still a strong unmet need for more effective and tolerable options. The present study summarizes and discusses recent evidence regarding the pharmacological and neuromodulatory treatment of PD. METHODS: MEDLINE, Cochrane Library, PsycINFO and Thomson Reuters's Web of Science were searched for clinical trials published between 2010 and 2018. We included all prospective experimental studies including randomized controlled trials (RCT) and other clinical trials with more than 10 patients. RESULTS: Only 11 articles met the inclusion criteria, including 4 RCT, 3 open clinical trials and 5 comparative clinical trials. RCT demonstrated efficacy of transcranial magnetic stimulation (TMS) in only one of two trials. Neither pindolol nor d-fenfluramine were effective in blocking flumazenil-induced panic attacks. Augmentation with quetiapine was not superior to placebo. Open trials indicated that escitalopram, vortioxetine and TMS may be effective. Comparative trials did not demonstrate superiority from any drug, but confirmed tranylcypromine, paroxetine, clonazepam and alprazolam as effective options. CONCLUSION: The current study confirmed the efficacy of tranylcypromine, paroxetine, clonazepam, alprazolam and escitalopram. Vortioxetine and TMS, with duration of 4 or more weeks, also seems to be effective. Quetiapine, pindolol and d-fenfluramine were not considered effective compounds.
