Psychosocial Burden of Psoriasis: A Systematic Literature Review of Depression Among Patients with Psoriasis
Abstract
Abstract Psoriasis is associated with various comorbidities with a notable psychosocial burden. This systematic literature review explores the burden of depression in patients with psoriasis, comparing it with that experienced by patients with other chronic medical conditions. Embase via Ovid, PubMed, and Cochrane Database of Systematic Reviews via Ovid were searched for peer-reviewed studies published in English between January 1, 2016 and December 6, 2021 that reported real-world evidence or observational studies involving at least 100 adults (age ≥ 18 years) with general (unspecified) or plaque psoriasis experiencing symptoms of depression (but not restricted to patients with a clinical diagnosis). Any report of depression or suicidality was eligible for inclusion. Systematic literature reviews reporting depression/suicidality in other chronic medical conditions were also included. Statistical analysis was not performed; the study was descriptive only. A total of 1744 records were identified, and after several defined screenings by two independent reviewers for publication year, relevance, and sample size, 82 publications were included. Psoriasis was significantly associated with depression. The prevalence of depression in patients with psoriasis ranged from 0.2% to 74.6%, with incidence from 4.83 to 91.9 per 1000 person-years. The prevalence of depression was generally higher among patients with more severe psoriasis than those with less severe disease (as determined by Psoriasis Area Severity Index [PASI] scoring system) and was more prevalent among women than men with psoriasis. Depression in psoriasis significantly reduced quality of life, including factors such as sexual dysfunction, sleep difficulties, subjective well-being, and addictions. Comorbid hypertension, hyperlipidemia, psoriatic arthritis, obesity, inflammatory bowel disease, diabetes, and statin use were all associated with increased depression risk in patients with psoriasis. This systematic literature review found that the burden of depression in psoriasis is no lower than in other chronic medical conditions. Greater awareness of the psychological impact of psoriasis would improve care and management, which should incorporate psychological interventions.
