Association between panic disorder and childhood adversities: a systematic review and meta-analysis

Effects of antidepressant on FKBP51 mRNA expression and neuroendocrine hormones in patients with panic disorder

OBJECTIVE

The purpose of this study was to investigate the effects of escitalopram on the peripheral expression of hypothalamic-pituitary-adrenal (HPA) axis-related genes (FKBP51, HSP90, NR3C1 and POMC) and HPA-axis hormones in patients with panic disorder (PD).

METHODS

Seventy-seven patients with PD were treated with escitalopram for 12 weeks. All participants were assessed for the severity of panic symptoms using the Panic Disorder Severity Scale (PDSS). The expression of HPA-axis genes was measured using real-time quantitative fluorescent PCR, and ACTH and cortisol levels were measured using chemiluminescence at baseline and after 12 weeks of treatment.

RESULTS

At baseline, patients with PD had elevated levels of ACTH and cortisol, and FKBP51 expression in comparison to healthy controls (all p < 0.01). Correlation analysis revealed that FKBP51 expression levels were significantly positively related to cortisol levels and the severity of PD (all p < 0.01). Furthermore, baseline ACTH and cortisol levels, and FKBP51 expression levels were significantly reduced after 12 weeks of treatment, and the change in the PDSS score from baseline to post-treatment was significantly and positively related to the change in cortisol (p < 0.01).

CONCLUSIONS

The results suggest that PD may be associated with elevated levels of ACTH and cortisol, and FKBP51 expression, and that all three biomarkers are substantially decreased in patients who have received escitalopram treatment.

Early Trauma Subtypes are Differentially Related to Anxiety Symptomatology and Suicidal Ideation in Panic Disorder

OBJECTIVE

Early trauma significantly affects the severity of panic disorder (PD) symptoms and suicidal ideation. However, few studies have explored the specific effects of different early trauma subtypes on PD. This study analyzed how childhood trauma subtypes, including general, physical, emotional, and sexual, influence panic and phobia levels and suicidal ideation in adults with PD and healthy controls (HCs).

METHODS

In total, 455 adults with PD and 149 HCs participated in this study. The independent variables were sociodemographic and clinical variables such as coping strategies and early trauma subtypes from the Early Trauma Inventory Self Report-Short Form. The dependent variables were the Albany Panic and Phobia Questionnaire (APPQ), the Panic Disorder Severity Scale, and the Scale for Suicide Ideation (SSI).

RESULTS

Early emotional trauma significantly influenced the APPQ scores, whereas early physical trauma significantly influenced the SSI scores in patients with PD. However, in HCs, only early emotional trauma was significantly associated with the APPQ and SSI scores.

CONCLUSION

These findings highlight the influence of early trauma subtypes on the phobic symptom severity of PD and suicidal ideation among patients with PD. Early emotional trauma is associated with the severity of phobic symptoms, whereas early physical trauma is associated with suicidal ideation, suggesting distinct clinical outcomes based on the type of trauma in patients with PD.

Inducible Laryngeal Obstruction Differential Diagnosis in Adolescents and Adults: A Tutorial

Inducible laryngeal obstruction (ILO), formerly referred to as paradoxical vocal fold motion and vocal cord dysfunction, is a complex disorder of the upper airway that requires skillful differential diagnosis. There are several medical conditions that may mimic ILO (or which ILO may mimic) that should be considered in the differential diagnosis before evidence-supported behavioral intervention is initiated to mitigate or eliminate this upper airway condition. A key in treatment planning is determination of an isolated presentation of ILO or ILO concurrent with other conditions that affect the upper airway. Accurate, timely differential diagnosis in the clinical assessment of this condition mitigates delay of targeted symptom relief and/or insufficient intervention. Accurate assessment and nuanced clinical counseling are necessary to untangle concurrent, competing conditions in a single patient. This tutorial describes the common and rare mimics that may be encountered by medical professionals who evaluate and treat ILO, with particular attention to the role of the speech-language pathologist. Speech-language pathologists receive referrals for ILO from several different medical specialists (allergy, pulmonology, and sports medicine), sometimes without a comprehensive team assessment. It is paramount that speech-language pathologists who assess and treat this disorder have a solid understanding of the conditions that may mimic ILO. Summary tables that delineate differential diagnosis considerations for airway noise, origin of noise, symptoms, triggers, role of the speech-language pathologist, and β-agonist response are included for clinician reference. A clinical checklist is also provided to aid clinicians in the critical assessment process.
