OBJECTIVE: In this systematic review and meta-analysis of psoriatic arthritis (PsA) studies, we pooled data from existing literature to (1) estimate the prevalence of mental health disorders in PsA patients and (2) compare disease activity in PsA patients with and without these comorbidities.
METHOD: We searched PubMED, Web of Science, Scopus, PsycINFO and the Cochrane Library using a predefined protocol in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Where possible, meta-analysis was performed using random effects model. Prevalence estimates were pooled according to the severity of mental health disorders.
RESULTS: A total of 24 studies, amounting to 31,227 PsA patients, were included for review. Anxiety and depression were the only consistently reported mental health disorders, defined using a range of screening criteria/thresholds. Anxiety prevalence ranged from 4 to 61% with a pooled estimate of 33% (95%CI 17 to 53%) having at least mild anxiety and 21% (95%CI 14 to 29%) at least moderate. Depression prevalence ranged from 5 to 51%, with 20% (95%CI 8 to 35%) having at least mild and 14% (95%CI 8 to 21%) at least moderate. Only two studies compared disease activity according to the presence of mental health comorbidities; both reported higher disease activity and pain among those with comorbid anxiety and depression.
CONCLUSIONS: Anxiety and depression are highly prevalent among PsA patients. Studies of other mental health disorders were scarce. More studies are needed on the impact of these comorbidities on disease activity and long-term outcomes.Key Points• One in three patients with psoriatic arthritis has at least mild anxiety, while 1 in 5 reported at least mild depression.• PsA patients with anxiety and/or depression reported greater disease activity.• More research is needed on other mental health comorbidities, particularly sleep, suicide/self-harm and substance misuse.
