Abstract
BACKGROUND: Hereditary angioedema (HAE) is associated with relevant disease-related burden. We aimed at investigating prevalence of depression and anxiety in patients with HAE in Leipzig, Germany. METHODS: Questionnaire-based evaluation of medical history, Angioedema Control Test (AECT), Angioedema Quality of Life Questionnaire (AE-QoL), Generalized Anxiety Disorder Scale-7 (GAD-7), and Hospital Anxiety and Depression Scale (HADS). RESULTS: Thirty-seven patients with HAE were included (31 females, mean age 49.6 ± 17.5 years). A mean diagnostic delay between first symptoms and correct diagnosis of 14.2 ± 14.5 years was detected. Patients aged <50 years (n = 18) had been diagnosed significantly earlier with HAE than older patients (p = <0.001). In 6 patients (16.2%), unnecessary medical interventions were performed and 14 patients (43.8%) reported at least 1 HAE-related death of a family member. Psychological stress was the most common triggering factor (96.2%). HADS scores revealed depression in 5/37 patients (13.5%) and anxiety in 16/37 (43.2%), GAD-7 score indicated anxiety in 9/36 (25%) participants. Patients receiving long-term prophylactic treatment (n = 17, 45.9%) showed significantly better disease control (AECT; p = <0.001) and quality of life (AE-QoL; p = <0.001) compared to those with on-demand treatment only. Patients with long-term prophylactic treatment showed significantly lower scores for anxiety and depression at GAD-7 (p = 0.011) and HADS (anxiety: p = 0.021; depression: p = 0.008). In 5 patients, treatment regime was changed as AECT score indicated insufficient disease control. Subsequently, we measured significant improvement of quality of life (AE-QoL, p = 0.04) and disease control (AECT; p = 0.032). CONCLUSION: Anxiety was a frequent burden in our study group and showed a significant association with low disease control. Our data indicate that prophylactic HAE treatment can improve psychosocial burden of HAE.
