Aim: People with rheumatic diseases (PRD) remain vulnerable in the era of the COVID‐19 pandemic. We formulated recommendations to meet the urgent need for a consensus for vaccination against SARS‐CoV‐2 in PRD.Methods: Systematic literature reviews were performed to evaluate: (a) outcomes in PRD with COVID‐19; (b) efficacy, immunogenicity and safety of COVID‐19 vaccination; and (c) published guidelines/recommendations for non‐live, non‐COVID‐19 vaccinations in PRD. Recommendations were formulated based on the evidence and expert opinion according to the Grading of Recommendations Assessment, Development and Evaluation methodology.Results: The consensus comprises 2 overarching principles and 7 recommendations. Vaccination against SARS‐CoV‐2 in PRD should be aligned with prevailing national policy and should be individualized through shared decision between the healthcare provider and patient. We strongly recommend that eligible PRD and household contacts be vaccinated against SARS‐CoV‐2. We conditionally recommended that the COVID‐19 vaccine be administered during quiescent disease if possible. Immunomodulatory drugs, other than rituximab, can be continued alongside vaccination. We conditionally recommend that the COVID‐19 vaccine be administered prior to commencing rituximab if possible. For patients on rituximab, the vaccine should be administered a minimum of 6 months after the last dose and/or 4 weeks prior to the next dose of rituximab. Post‐vaccination antibody titers against SARS‐CoV‐2 need not be measured. Any of the approved COVID‐19 vaccines may be used, with no particular preference.Conclusion: These recommendations provide guidance for COVID‐19 vaccination in PRD. Most recommendations in this consensus are conditional, reflecting a lack of evidence or low‐level evidence.
Medium-sized artery aneurysms are rare in patients with systemic lupus erythematosus (SLE). We report on a 21-year-old Chinese man with SLE and secondary antiphospholipid syndrome (APS) who presented with acute abdominal pain due to a ruptured right hepatic artery aneurysm. He was also found to have aneurysms of the left hepatic artery and splenic artery on autopsy. There have been only eight cases of hepatic artery aneurysm and one case of splenic artery aneurysm associated with SLE in the English literature. Abdominal aneurysm must be suspected in SLE patients presenting with acute abdominal pain, haemoperitoneum or occult bleeding.

Background/Objectives: Neutralizing autoantibodies against type I interferons, particularly interferon-alpha (IFN-α), have been implicated in severe COVID-19 outcomes. This study investigated the prevalence and functional significance of anti-IFN-α autoantibodies (AAbs) in hospitalized unvaccinated COVID-19 patients and their association with COVID-19 disease severity. Methods: We retrospectively analyzed serum samples from 122 hospitalized COVID-19 patients (asymptomatic/mild: n = 69, moderate: n = 35, severe/critical: n = 18) and 32 healthy uninfected controls. Anti-IFN-α AAbs were quantified using a commercial enzyme-linked immunosorbent assay (ELISA) kit, with functional neutralization assessed via competitive ELISA and STAT1 phosphorylation inhibition. Statistical comparisons were performed using one-way ANOVA for parametric data and the Kruskal–Wallis test for non-parametric variables. Results: Anti-IFN-α AAbs were detected in 24.6% of COVID-19 patients, with all clinical subgroups showing significantly higher titers compared to healthy controls (p < 0.05). Although no significant differences in anti-IFN-α AAb levels were found between mild, moderate, and severe cases, patients with severe or critical COVID-19 had markedly higher mean titers (10,511.3 ng/mL) compared to non-severe (mild + moderate) cases (375.2 ng/mL, p < 0.001). Strongly neutralizing anti-IFN-α AAbs, with high titers (>20,000 ng/mL) and the ability to inhibit STAT1 phosphorylation, were identified in three severe COVID-19 cases. Anti-IFN-α AAb levels correlated positively with CRP (r = 0.80, p < 0.0001), LDH (r = 0.80, p = 0.001), and neutrophil count (r = 0.52, p = 0.003), and negatively with lymphocyte count (r = −0.59, p = 0.0006). Conclusions: Elevated and functionally neutralizing anti-IFN-α AAbs were associated with severe COVID-19. These findings support their role as a risk factor for poor outcomes and emphasize the importance of early COVID-19 vaccination. Screening may help identify high-risk individuals, particularly those unvaccinated or with immune vulnerabilities.
