Purpose: To summarize the data published over the last 5 years in the European Union related to the health-related quality of life (HRQoL) of patients with psoriasis and its conditioning factors.Methods: International electronic databases and gray literature were searched to identify studies conducted on patient-reported outcomes in patients with psoriasis, published in Europe between January 1, 2009 and December 31, 2013. Bibliographic references were hand-searched. Editorials, letters, commentaries, opinion papers, and studies related to specific treatments were excluded.Results: A total of 46 studies met the inclusion criteria, 27 of them reporting data related to HRQoL or its conditioning factors. The publications reviewed highlighted the substantial negative impact of psoriasis on patients' HRQoL. Most of the studies that analyzed the relationship between HRQoL and sociodemographic characteristics described a relation between gender (female) and age (young patients) and poorer HRQoL. An association between HRQoL impairment and visibility of skin lesions and disease activity and severity was also established. Skin discomfort and pruritus were identified as elements that negatively influenced HRQoL. Use of biological agents had a positive impact on HRQoL and on treatment satisfaction, a better HRQoL being seen in patients treated with systemic therapies and biologics.Conclusions: HRQoL has been broadly addressed in patients with psoriasis in Europe. Several disease- and patient-related factors contributed to its deterioration. Therapeutic measures with proven effectiveness in controlling disease symptoms and reducing PASI should be considered in patients with a severe disease who have a poorer HRQoL. [ABSTRACT FROM AUTHOR]
