Prevalence of Psychiatric Disorders among Patients with Granulomatosis with Polyangiitis (Wegener's) and the Predictive Role of Personality Traits

Wegener’s disease is an autoimmune condition affecting the respiratory tract and kidneys. Mental health assessment is crucial due to the impact of psychological disorders on the immune system. Despite this, there is limited community-based research on psychiatric disorders and personality traits among patients with Wegener's disease.

This study aimed to investigate the prevalence of psychiatric disorders and examine the predictive role of personality traits among patients with Wegener's disease.

A total of 100 patients met the inclusion and exclusion criteria, and all of them were selected to participate in the study. Out of them, 75 individuals completed the questionnaires. The instruments included the SCL-90 questionnaire and the NEO Big Five personality traits. The data were analysed using Stata software, and the prevalence of psychiatric disorders in different patient groups was determined using the chi-square method. The predictive role of personality traits in mental disorders was examined using multivariate regression.

The results revealed that paranoia (53.3%) and depression (44%) had the highest prevalence in terms of psychiatric disorders, while psychosis (17.3%) and hostility (25.33%) had the lowest prevalence. Additionally, the findings demonstrated a positive correlation between most psychiatric disorders and the neuroticism personality trait.

Given the influence of mental disorders on the immune system in Wegener's disease, it is essential to provide psychological care for these patients.
