A significantly increased risk for overall mortality was observed among patients with ankylosing spondylitis (AS), but not among those with psoriatic arthritis (PsA), according to findings from a systematic review and meta-analysis published in Arthritis Care & Research (Hoboken). However, cardiovascular-specific mortality was higher among both patients with PsA and AS compared with the general population.
Authors of the current analysis sought to examine the cause-specific and all-cause mortality in patients with PsA and AS, based on available literature.
A total of 3124 articles were screened by title and abstract, with 88 full-text articles selected for inclusion in the analysis. Overall, 19 studies met prespecified inclusion criteria, with 11 on PsA, 7 on AS, and 1 study discussing outcomes for both AS and PsA. The studies selected were conducted in 10 countries: Canada, Denmark, France, Hong Kong (China), Korea, Norway, Sweden, Taiwan, the United Kingdom, and the United States. The study period, including follow-up analyses, varied from 4 to 40 years.
Results showed that of the studies on PsA, no increased mortality was observed compared with the general population (relative risk [RR], 1.12; 95% CI, 0.96-1.30; n=10 studies). A higher all-cause mortality was reported among women with PsA compared with men with PsA (RR, 1.19; 95% CI, 1.04-1.36 vs RR, 1.02; 95% CI, 0.66-1.59, respectively). Although cardiovascular (CV), respiratory, and infection-specific mortality risks were significantly higher among patients with PsA (RR, 1.21; 95% CI, 1.06-1.38 vs RR, 3.37; 95% CI, 1.30-8.72; vs RR, 2.43; 95% CI, 1.01-5.84, respectively), cancer-associated mortality was not (RR, 1.01; 95% CI, 0.91-1.11).
A higher risk for all-cause death (RR, 1.64; 95% CI, 1.49-1.80; n=6 studies) and for death from CV causes (RR, 1.35; 95% CI, 1.01-1.81; n=3 studies) was reported among patients with AS compared with the general population. Further, in patients with AS, all-cause mortality was high among both men and women (RR, 1.56; 95% CI, 1.43-1.71 and RR, 1.85; 95% CI, 1.56-2.18, respectively).
The researchers concluded that the findings from this analysis underscore the importance of early screening and management of CV risk factors in patients with PsA and AS.
