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.

The First Effect of COVID-19 Pandemic on Starting Biological Disease Modifying Anti-Rheumatic Drugs: Outcomes from the TReasure Real-Life Database.

OBJECTIVE: The coronavirus disease 2019 pandemic has been resulting in increased hospital occupancy rates. Rheumatic patients cannot still reach to hospitals, or they hesitate about going to a hospital even they are able to reach. We aimed to show the effect of the first wave of coronavirus disease 2019 pandemic on the treatment of biological disease-modifying anti-rheumatic drugs in patients with rheumatoid arthritis or spondyloarthritis. METHODS: Patients were divided into three groups as follows: pre-pandemic (Pre-p: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within 6 months before March 11, 2020); post-pandemic A (Post-p A: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the first 6 months after March 11, 2020); post-pandemic B (Post-p B: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the second 6 months). RESULTS: The number of rheumatoid arthritis patients in the Post-p A and B groups decreased by 51% and 48%, respectively, as compared to the Pre-p group similar rates of reduction were also determined in the number of spondyloarthritis patients. The rates of tofacitinib and abatacept use increased in rheumatoid arthritis patients in Post-p period. CONCLUSION: The number of rheumatoid arthritis and spondyloarthritis patients starting on biological disease-modifying anti-rheumatic drugs for the first time decreased during the first year of the coronavirus disease 2019 pandemic.

Evaluation of the frequency and intensity of COVID-19 in patients with ankylosing spondylitis under anti-TNF therapy.

BACKGROUND: Dear Editor, After the coronavirus disease 2019 (COVID-19) pandemic affected the whole world, rheumatologists began to think about how COVID-19 will progress in patients with inflammatory conditions. High cytokine levels play a role in the pathophysiology of COVID-19 infection. Tumor necrosis factor alpha (TNF-α) is a proinflammatory cytokine known to have a key role in the pathogenesis of chronic immune-mediated diseases. AntiTNF therapy may cause an increase in active tuberculosis, other granulomatous diseases, and serious infections [1]. According to many studies, rheumatological diseases have not been identified as a risk factor for severe COVID-19 infection [2]. Should significantly increased cytokine levels during COVID-19 infection make us consider anticytokine therapies that may be used in the treatment of patients with COVID-19 a risk? We aimed to explore whether the frequency of COVID-19 infection increased, the effect of comorbidities on the frequency of infection, and whether the severity of the disease and need for intensive care support increased in patients who used anti-TNF agents. We performed a retrospective case-control study between March and December 2020 in Sakarya University Training and Research Hospital. Retrospectively, we evaluated whether there was a difference in the frequency and severity of COVID-19 in our patients diagnosed with ankylosing spondylitis (AS), 77 of whom were using anti-TNF and 49 of whom didn't use anti-TNF. Hospitalization and intensive care unit (ICU) requirements were evaluated as endpoints. In the anti-TNF group, patients used adalimumab, etanercept, certolizumab, infliximab, and golimumab. Patients were questioned at an outpatient clinic in person or by phone. Seventy-seven patients with AS using anti-TNF agents (58 males, 19 females) and 49 patients with AS (38 males, 11 females) not using anti-TNF agents were included in the study (p = 0.943). Mean age of patients using antiTNF agents was 41.53 ± 10.38, and mean age of patients not using anti-TNF agents was 42.94 ± 10.86 (p = 0.468). Thirty-three (42.9%) patients were smokers in the antiTNF group, while 23 (46.9%) patients were smokers in the group not using TNFi (p = 0.791). There was 12 pack-year smoking in the anti-TNF group, and 14 pack-year smoking in not using TNFi (p = 0.623). The frequency of diabetes mellitus (DM), hypertension (HT), amiloidosis, familial mediterranean fever (FMF), coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD) was similar in both groups (p = 0.403, p = 0.999, p = 0.521, p = 0.999, p = 0.999, respectively). Six patients using TNFi and 3 patients not using TNFi recovered from COVID-19 infection. However, this result was not statistically significant (p = 0.999). One patient using anti-TNF was hospitalized but with no need for admission to the ICU (p = 0.999). All 9 patients recovering from COVID-19 were male (p = 0.113). There were 2 (22.2%) smokers in the SARS-CoV-2 positive group and 54 (46.2%) smokers in SARS-CoV-2 negative group (p = 0.297). There was 37.5 pack-year smoking in SARS-CoV-2 positive group, and 12 pack-year smoking in SARS-CoV-2 negative group (p = 0.151). Nobody has comorbidities (DM, HT, amiloidosis, FMF, CAD, COPD) in SARS-CoV-2 positive group. There were patients with DM (5.1%), HT (15.4%), amiloidosis (1.7%), FMF (1.7%), CAD (0.9%) and COPD (0.9%) in SARS-CoV-2 negative group (p = 0.999, p = 0.356, p = 0.999, p = 0.999, p = 0.999, p = 0.999, respectively). Having comorbidities was not detected to be associated with frequency of COVID-19. 31 (40.3%) patients were using adalimumab, 25 (32.5%) patients were using etanercept, 13 patients were using (16.9%) certolizumab, 6 (7.8%) patients were using golimumab, and 2 patients (2.6%) were using infliximab in TNF group. Six patients using anti-TNF (2 adalimumab, 1 etanercept, 1 golimumab,2 infliximab) and 3 nonuser patients recovered from COVID-19 (p = 0.999). No statistically significant difference was found between SARS-CoV-2 positive and negative patients in terms of the types of anti TNF they used. Patients were called in March 2020, and they were advised to terminate their anti-TNF therapy, when the COVID-19 pandemic began. Among those who used antiTNF, 2 (33.3%) people who had COVID-19 and 38 (53.5%) people who did not have COVID-19 interrupted treatment (p = 0.419). Anti-TNF users who did not have COVID-19 stopped taking the treatment for an average of 3 months (min 2-max 4 months) starting from March 2020, and the patients who had COVID-19 (p = 0.102) stopped taking the treatment for 1.5 months (min 1-max 2 months). Duration of interrupting TNFi was not significant for the risk of COVID-19. Comorbidities, older age, and the presence of active disease have been associated with worse outcomes in previous studies [3]. In our study, the anti-TNF using and the nonuser groups were similar according to age, sex, and comorbidities. Although comorbidities in COVID-19 are associated with severe disease in the literature, we did not find a significant difference in our study. This result is probably related to our insufficient number of patients. As a result, we found that the use of anti-TNF did not increase the frequency and severity of COVID-19. In a recently published multicenter study, it was stated that the use of biological DMARDs in patients with inflammatory rheumatic diseases was not significantly associated with a worse outcome of COVID-19. But unlike our study, having no comorbidities was associated with a decreased risk of a worse outcome [4]. There are currently studies investigating the therapeutic utility of infliximab and adalimumab in hospitalized COVID-19 patients [5]. The results of these studies are very important. The usability of TNFi in treatment and at which stage of the disease anti-TNF agents can be used are wondered. We will see the course of the disease all over the world after the administration of the COVID-19 vaccines, but we still need more information about effective and safe treatment. RESULTS: The authors declare that there is no conflict of interest. DISCUSSION: The authors did not receive support from any organization for this work.

Preferences of inflammatory arthritis patients for biological disease-modifying antirheumatic drugs in the first 100 days of the COVID-19 pandemic

Background/aim: To evaluate treatment adherence and predictors of drug discontinuation among patients with inflammatory arthritis receiving bDMARDs within the first 100 days after the announcement of the COVID-19 pandemic. Materials and methods: A total of 1871 patients recorded in TReasure registry for whom advanced therapy was prescribed for rheumatoid arthritis (RA) or spondyloarthritis (SpA) within the 3 months (6­9 months for rituximab) before the declaration of COVID-19 pandemic were evaluated, and 1394 (74.5%) responded to the phone survey. Patients' data regarding demographic, clinical characteristics and disease activity before the pandemic were recorded. The patients were inquired about the diagnosis of COVID-19, the rate of continuation on bDMARDs, the reasons for treatment discontinuation, if any, and the current general disease activity (visual analog scale, [VAS]). Results: A total of 1394 patients (493 RA [47.3% on anti-TNF] patients and 901 SpA [90.0% on anti-TNF] patients) were included in the study. Overall, 2.8% of the patients had symptoms suggesting COVID-19, and 2 (0.15%) patients had PCR-confirmed COVID-19. Overall, 18.1% of all patients (13.8% of the RA and 20.5% of the SpA; p = 0.003) discontinued their bDMARDs. In the SpA group, the patients who discontinued bDMARDs were younger (40 [21­73] vs. 44 years [20­79]; p = 0.005) and had higher general disease activity; however, no difference was relevant for RA patients. Conclusion: Although the COVID-19 was quite uncommon in the first 100 days of the pandemic, nearly one-fifth of the patients discontinued bDMARDs within this period. The long-term effects of the pandemic should be monitored.
