Clinical outcomes of patients with COVID-19 and inflammatory rheumatic diseases receiving biological/targeted therapy.

BACKGROUND: Anti-cytokine treatments are used in the treatment of severe COVID-19. Other studies have shown statistical significance with TNF inhibitors but not with other biological/targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARD). OBJECTIVES: Compare the rate of severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) infection and the course and incidence of COVID-19 infection in patients who received b/tsDMARD with control patients. DESIGN: Analytical cross-sectional SETTINGS: Tertiary care hospital PATIENTS AND METHODS: All patients who applied to the rheumatology outpatient clinic between June 2020-March 2021 and received b/tsDMARD were included in the study. All patients with rheumatoid arthritis, psoriatic arthritis and spondyloarthritis who applied to the rheumatology outpatient clinic in the three months before March 2021 and did not receive b/tsDMARD were included as the control group. History of COVID-19 infection and treatments were recorded. Multivariate analysis was performed to assess factors associated with use of tumor necrosis factor (TNF) inhibitors and differences between specific biologic drugs. MAIN OUTCOME MEASURES: Rate of COVID-19 disease among patients using biological/targeted synthetic therapy and non-biological/targeted synthetic therapy. COVID-19 clinical outcomes (hospitalization, intensive care admission, mechanical ventilation and death). SAMPLE SIZE: 533 in total; 341 received b/tsDMARD, 212 in the control group that did not receive b/tsDMARD. RESULTS: One hundred patients (18%) had been infected with SARS-COV-2. The difference in SARS-COV-2 infection between b/tsDMARD and the control was statistically significant (13, 2% vs. 25, 9%, respectively) (P<.001). The hospital stays were longer in the controls (P<.001). Multinomial regression analysis revealed that COVID-19 negative patients were more likely to use tumor necrosis factor (TNF) inhibitors (OR: 2, 911; 95% CI: 1.727-4.908; P<.001) compared to COVID-19 positive participants. Multinomial logistic regression analysis indicated that hospitalized patients were more likely to use TNF inhibitors (OR: 11, 006; 95% CI: 3.447-35.138; P<.001) and there was no significant difference between b/tsDMARDs other than TNF inhibitors in frequency of hospitalization. CONCLUSIONS: Patients who were medicated with b/tsDMARD were less likely to be infected with COVID-19 and be hospitalized due to the infection. We have found that this effect was particularly dependent on the use of TNF inhibitors. LIMITATIONS: Conducted in a single center and unable to provide a homogeneous study population. CONFLICT OF INTEREST: None.

A Case of IgG4-related Mesenteritis and Ankylosing Spondylitis.

Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibroinflammatory disease of unknown etiology and pathogenesis, which can affect all organs. The most commonly involved organs are the pancreas, hepatobiliary system, salivary glands, orbits and lymph nodes. Rarely, the thyroid, pituitary, aorta, lung and kidney may also be involved; mesenteric involvement is rare. The association of IgG4-RD with some rheumatological diseases is observed; while there are data in the literature about rheumatoid arthritis and Sjögren syndrome, but association with ankylosing spondylitis is rare. Anti-tumor necrosis factor alpha (anti-TNFα) treatment has been tried in refractory IgG4-RD cases; but this case is of great interest in terms of progressive presentation under treatment with etanercept, an anti-TNFα agent, which is also used for the treatment. But, IgG4-related mesenteritis with ankylosing spondylitis receiving anti-TNFα therapy, which has also been tried in the treatment of IgG4 disease, has not been reported in the literature. Key Words: IgG4-related disease, Mesenteritis, Ankylosing spondylitis.

Evaluation of factors affecting the frequency and clinical course of COVID-19 in patients using anti-TNF-alpha agents.

OBJECTIVES: Patients being treated with anti-tumor necrosis factor-alpha (anti-TNF-alpha) agents were reported to have better prognosis related to COVID-19. We evaluated the factors affecting the frequency, clinical course, and outcome of COVID-19 in patients treated with anti-TNF-alpha agents. METHODS: Patients with rheumatoid diseases and chronic inflammatory bowel diseases treated with anti-TNF-alpha agents were evaluated retrospectively. The laboratory data in routine visits, frequency of COVID-19, pneumonia, hospitalization and/or intensive care unit (ICU) follow-up and, mortality were recorded. The factors related to COVID-19 frequency and clinical outcome were evaluated. RESULTS: A total of 324 patients (177 males [54.6%] and 147 females [45.4%], mean age: 45.3±12.16 years) was included in the study. In all, 44 (13.6%) patients had COVID-19; of these, 11 (25%) developed pneumonia, 7 (15.9%) were hospitalized, and 1 (2.3%) was followed up in ICU. There was no mortality. The patients with COVID-19 pneumonia were older (mean age: 52±11 years versus 41±12 years, p=0.01), had hypertension and coronary artery disease more frequently (5 cases [55.6%] versus 4 cases [44.4], p=0.02 and 2 cases [100%] versus 0 cases [0%], p=0.014, respectively), and lower eosinophil % (1.35±1.79% versus 2.3±1.45%, p=0.016). The diabetes mellitus was more frequent (66.7 versus 33.3%, p=0.013), and mean eosinophil % was lower among inpatients compared with outpatients (1.29±2.22% versus 2.19±1.37%, p=0.02). CONCLUSIONS: We concluded that the patients treated with anti-TNF-alpha agents having COVID-19 might have mild clinical course and better prognosis.

Capillaroscopic findings and vascular biomarkers in systemic sclerosis: Association of low CD40L levels with late scleroderma pattern.

OBJECTIVE: To determine the relationship between vascular biomarkers reflecting the vascular injury and neoangiogenesis with capillaroscopic changes in systemic sclerosis (SSc). METHODS: Nailfold video-capillaroscopy (NVC) was performed qualitatively (early, active and late scleroderma patterns) in 72 SSc patients (66 female) fulfilling ACR/EULAR (2013) criteria. Serum samples of patients were collected and analysed by flow cytometer with multiplex kits of sCD40L, tPA, MCP-1, sE-selectin, IL-8, IL-6, VEGF, sP-selectin, TGF-ß1 and VCAM at the same time with NVC. RESULTS: Compared to healthy subjects; tPA (p=0.02), MCP-1 (p=0.001), sE-selectin (p=0.008) and TGF-ß1 (p=0.001) levels were significantly higher, however sP-selectin (p=0.011) and IL-8 (p=0.001) levels were lower in SSc patients. SSc patients were defined according to NVC patterns as 'early' (n=10), 'active' (n=37) and 'late' (n=25). According to NVC patterns of SSc patients, only sCD40L levels were significantly lower in the 'late' group (p=0.039). The other markers were similar among NVC groups. CONCLUSIONS: NVC is a useful method for investigating the vascular pathogenesis and severity of SSc. Although the levels were similar to healthy controls in patients with early/active NVC patterns, there were lower sCD40L serum levels in patients with late NVC pattern. CD40L may have a role in the early/active phase of vascular involvement.
