Mortality in psoriatic arthritis patients, changes over time, and the impact of COVID-19: results from a multicenter Psoriatic Arthritis Registry (PsART-ID)

Methods: From the prospective, multicenter PsART-ID (Psoriatic Arthritis Registry-International Database), patients from Turkey were analyzed by linking the registry to the Turkish Cause of Death Registry. The outcome of interest was death from any cause, pre-pandemic (since the onset of registry—March 2014–March 2020), and during the pandemic (March 2020–May 2021). The crude mortality rate and standardized mortality ratio (SMR) were determined. Results: There were 1216 PsA patients with a follow-up of 7500 patient-years. Overall, 46 deaths (26 males) were observed. In the pre-pandemic period, SMR for PsA vs the general population was 0.95 (0.61–1.49), being higher in males [1.56 (0.92–2.63)] than females [0.62 (0.33–1.17)]. The crude mortality rate in PsA doubled during the pandemic (pre-pandemic crude mortality rate: 5.07 vs 10.76 during the pandemic) with a higher increase in females (2.9 vs 8.72) than males (9.07 vs 14.73). Conclusion: The mortality in PsA was found similar to the general population in the pre-pandemic era. The mortality rates in PsA doubled during the pandemic. Whether PsA patients have more risk of mortality than the general population due to COVID-19 needs further studies.Key Points• Decrease in mortality in PsA might be expected with the more effective treatment options and better disease control.• A crude mortality rate is comparable to the general population and not increased until the pandemic.• Currently, there is a 2-fold increase in crude mortality rate possibly due to the COVID-19.
