Objectives
The systemic autoinflammatory diseases are rare conditions, to date data on COVID-19 infection and vaccination safety are scarce. Agents targeting innate immune pathways have transformed management of affected patients, and their outcomes are of wider interest given the role of inflammation in both viral clearance and severe COVID-19 disease. We surveyed patients with systemic autoinflammatory disease on biologic therapy to determine the prevalence and outcomes of COVID-19 infection and to gather early safety data on vaccination.
Methods
Electronic medical records of 248 patients with systemic autoinflammatory disease on biologic therapy at a national centre were reviewed. Patients were then surveyed in clinic or using a web-based survey.
Results
In the cohort of 248 patients, no deaths were recorded. 175 survey responses were received. Among the respondents, 27 reported suspected COVID-19 infection, of which 14 were confirmed by testing (8.0%). Two patients required admission due to dehydration. No patient required respiratory support or intensive care. 138 doses of COVID-19 vaccine had been administered to 130 patients. Side effects were reported following 71/138 (51.4%) administrations and were consistent with a flare of the underlying disease in 26/138 (18.8%) instances. No serious adverse events or hospital admissions were reported following vaccination.
Conclusions
These data, including the largest published series of patients on anti-Interleukin-1/6 biologics to receive any adenoviral vector or mRNA vaccine, show no serious early concerns regarding vaccination and will provide an urgently needed resource to inform decision making of these patients and their clinicians.
