N2  - AIM: Chi et al. (Am J Clin Dermatol; 31(5): 798-807) and Singh et al (J Am Acad Dermatol; 77(3): 425-440.e2) each conducted a systematic review and meta-analysis of observational studies examining the relationship between suicidality and psoriasis. SETTING AND DESIGN: Chi et al. included only cohort studies while Singh et al. included cohort, cross-sectional and case-control studies. PRIMARY EXPOSURE AND OUTCOME: The primary outcome, suicidality was assessed in people with psoriasis (exposure) and people with no psoriasis. Analyses were separated for suicidal ideation and behaviour. <br><br>RESULTS: Chi et al. included five population-based cohort studies that were considered to be of high quality according to the Newcastle-Ottawa-Scale (NOS). They found no significant increase in the risk of suicide (risk ratio [RR] 1.13; 95% confidence interval [CI] 0.87-1.46), suicide attempt (RR 1.25; 95% CI 0.89-1.75), or suicidality (RR 1.26; 95% CI 0.97-1.64) among people with psoriasis. Singh et al. included 18 studies that were rated to be of medium to high quality according to NOS. They found a pooled odds ratio (OR) for suicidal ideation among patients with psoriasis of 2.05 (95% CI, 1.54-2.74). For suicidal behaviours (combined attempted and completed suicides) a pooled OR of 1.26 (95% CI, 1.13-1.40) was obtained, suggesting a higher risk of these behaviours in people with psoriasis. Subgroup analysis showed that patients with psoriasis were more likely to attempt suicides (OR, 1.32; 95% CI, 1.14-1.54) and complete suicide (OR, 1.20; 95% CI, 1.04-1.39) than those without psoriasis. <br><br>CONCLUSION: Singh et al. concluded that patients with psoriasis have a significantly higher risk of suicidal ideation, suicide attempts, and completed suicides, while Chi et al concluded that the available limited, very low-quality evidence does not support the notion of an association between psoriasis on the one hand, and suicide, suicidal ideation and attempts on the other.
