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.

The effects of COVID-19 infection on the mortality of patients receiving rituximab therapy.

BACKGROUND: Rituximab (RTX) is an important immunosuppressive agent used for many rheumatologic diseases. This study investigated the factors affecting mortality and mortality due to COVID-19 infection in patients receiving RTX. METHODS: From March 2020 to November 2021, 111 patients who were followed up at a tertiary center with a diagnosis of any rheumatologic disease and who were diagnosed with COVID-19 were enrolled out of 336 patients who received at least one dose of RTX. Age, COVID-19 vaccination status, comorbidities, and some laboratory parameters were determined. The association between them and COVID-19 infection was investigated. In addition, patients were divided into two groups: those with rheumatoid arthritis (RA) and those without RA, and factors affecting mortality were studied. RESULTS: Thirty (27.0%) of the total 111 patients treated with RTX who tested positive for COVID-19 died. Among these patients, 19 (32.7%) of 58 patients diagnosed with RA died. Of the 53 patients diagnosed with non RA disease, 11 (20.7%) died. Age (p = 0.003, OR: 1.058, 95% CI: 1.025-1.097) and age at diagnosis (p = 0.047, OR: 1.032, 95% CI: 1.000-1.064) were the lowest against COVID-19 infection. Rate of vaccination of at least two doses (p = 0.000, OR: 0.170, 95% CI: 0.065-0.491), number of comorbid conditions (p = 0.001, OR: 1.530, 95% CI: 1.202-1.949), CKD (p = 0.003, significance was found between OR: 7.000, 95% CI: 1.926-25.439) and DM (p = 0.000, OR: 6.978, 95% CI: 2.499-19.483) and death. CONCLUSION: As a result of the study, it was found that RTX treatment in particular increased the risk of death from COVID-19 infection. However, vaccination against COVID-19 has a very important place in this patient group. It is important that vaccination is administered at the full dose and adjusted according to the RTX treatment time, and that the dose and timing of RTX treatment are regulated.

Attitudes of patients with a rheumatic disease on drug use in the COVID-19 pandemic.

BACKGROUND: Anti-rheumatic drugs can increase the predisposition to infection, and patients may be unaware of continuing their treatment during the COVID-19 pandemic. OBJECTIVE: This study aimed to assess whether patients maintain their treatment for rheumatic conditions during the pandemic period and determine the factors responsible for discontinuation. METHODS: Patients were randomly selected from the prospectively collected database of our tertiary referral center. The patients were interviewed by telephone through a standardized closed-ended questionnaire, which is targeting the continuity of the treatment plan and the considerations related to the individual choice. The patients were asked whether they hesitated to visit the hospital for follow-up or intravenous drug administration. RESULTS: A total of 278 patients completed the questionnaire. While 62 of the patients (22.3%) had reduced or interrupted the treatment, only 11 patients (3.9%) stopped the treatment completely. A significant difference was observed between the duration of illness and the discontinuation of treatment. (p = 0.023) There was a significant difference in disease activity between the group that stopped treatment and continued treatment. (p = 0.001) There was no statistically significant difference in other demographic characteristics. One hundred thirty-five patients (48.6%) made the treatment decision by themselves, and 80% continued the treatment. Reasons for stopping the treatment were anxiety (48.4%), not being able to go to the hospital for intravenous treatment (45.1%), and not being able to find the drug (6.5%). CONCLUSION: Since patients with long-term illnesses were found to be significantly more likely to stop their treatment, this group of patients should be monitored.

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.
