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

BACKGROUND: This study aimed to assess the mortality of PsA before and during the COVID-19 pandemic. 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.

What are the main barriers to achieve minimal disease activity in psoriatic arthritis in real life?

OBJECTIVES: Minimal disease activity (MDA) is an important target in patients with psoriatic arthritis (PsA), however it is also criticised for having a low threshold for patient reported outcomes (PRO).The aim of the study was to assess the prevalence of MDA and its components in patients with PsA and to evaluate disease characteristics and patterns in patients with or without MDA (MDA+ or MDA-). METHODS: PsArt-ID (Psoriatic Arthritis-International Database) is a prospective, multicentre web-based registry. PsA patients who had at least 1 year of disease duration and had full data for MDA were included for this analysis (n=317). Patients were considered in MDA+ when they met at least 5/7 of the MDA criteria. RESULTS: MDA was achieved in 46% patients. Within MDA- patients, body surface area (51.2%) and swollen joint count (53.5%) domains could still be achieved in the majority and 93.5% of them had no enthesitis using the Leeds enthesitis index. Of 170 patients with MDA-, 90 patients did not fulfill all 3 PROs of MDA. Mono-arthritis subtype (RR: 2.01), absence of enthesitis (RR: 1.570) and absence of distal interphalangeal (DIP) joint disease (RR: 1.1) were associated with higher probability of achieving MDA. CONCLUSIONS: The MDA criteria provide an objective target for treatment in trials and clinical practice; however, in real life PROs are the most significant barriers to achieve MDA. The presence of DIP joints disease makes it difficult to reach MDA due to active PROs.
