ABSTRACT
Atopic dermatitis (AD) is a common inflammatory skin condition that significantly affects patients' lives and imposes both economic and non-economic burdens. The precise societal and individual consequences of AD remain incompletely understood. This study aimed to characterize AD in Portuguese patients and assess its personal, familial, and societal implications, including health status and quality of life. The research, conducted from June 2019 to January 2020, involved 204 confirmed AD patients in Portugal, who completed a 70-question questionnaire. Results show that, on average, patients experienced a two-year delay in diagnosis, with two-thirds having allergic comorbidities. Late-onset AD (after age 20) was found to be correlated with worsening symptoms post-diagnosis. Globally, patients reported substantial effects on health, quality of life, and mental well-being. Effects include significant levels of anxiety, frustration and sleep disorders. Severe AD correlated with more suffering and reduced perceived health, indicating a link between disease severity and quality of life. Remarkably, despite questionable effectiveness, 92% of severe AD patients were prescribed antihistamines, while only 19% received biological treatments. In Portugal, delayed AD diagnosis hinders timely treatment, and despite its profound impact and high comorbidity rates, AD patients tend to remain undertreated. Recognizing the personal and societal repercussions is crucial for enhancing care, contributing to improving QoL, social functioning and global well-being.
