Introduction: Psoriatic Arthritis (PsA) and Ankylosing spondylitis (AS) are chronic inflammatory diseases associated with a higher risk of cardio-metabolic comorbidities compared to the general population. Individual studies examining mortality in these patients have produced conflicting results. We performed a systematic review and meta-analysis to analyze the all-cause and cause-specific mortality in PsA and AS from the available literature. Methods: A comprehensive database search was performed for studies reporting all-cause or cause-specific mortality in patients with PsA and AS compared with the general population. Pooled relative risks (RRs) were calculated using random-effects model. Results: We included 19 studies (11 of PsA, 7 of AS, 1 of both). In PsA studies, there was no increased mortality compared to the general population (RR: 1.12, 95% CI: 0.96-1.30, 10 studies). We found a higher all-cause mortality in females (RR= 1.19, 95% CI: 1.04-1.36) but not in male (RR: 1.02, 95% CI 0.66-1.59) PsA patients. Cardiovascular, respiratory, and infection specific mortality risks were significantly higher for PsA patients (RR: 1.21, 95% CI: 1.06-1.38; RR: 3.37, 95% CI: 1.30-8.72; and 2.43, 95% CI: 1.01-5.84, respectively), but not cancer-related mortality (RR: 1.01, 95% CI: 0.91-1.11). In AS, we found a higher risk of death from all causes (RR 1.64, 95% CI: 1.49-1.80, 6 studies) and cardiovascular causes (RR 1.35, 95% CI: 1.01-1.81, 3 studies) compared to the general population. All-cause mortality was high in both males (RR 1.56, 95% CI: 1.43-1.71) and female (RR 1.85, 95% CI: 1.56-2.18) AS patients. The included AS studies did not report mortality data for non-cardiovascular causes. Conclusion: This systematic review and meta-analysis showed a significantly increased risk of overall mortality in AS, but not PsA. Cardiovascular-specific mortality was higher for both PsA and AS, which emphasizes the importance of early screening and management of cardiovascular risk factors.
