Post-COVID general health symptoms in patients with immune-mediated inflammatory diseases.

Abstract

Background: Post-COVID entails persistent symptoms following a presumed or confirmed SARS-CoV-2 infection. This study aims to evaluate post-COVID general health symptoms reported by patients with IMIDs.

Methods: An online questionnaire was distributed to IMID patients on systemic therapy at dermatology, rheumatology, and gastroenterology departments in the Netherlands. General health symptoms were compared between patients with and without prior SARS-CoV-2 infection. Multivariable logistic regression was used to adjust for disease-related factors and known post-COVID risk factors. Self-reported prevalence of post-COVID symptoms was assessed by asking patients if they linked their symptoms to the previous SARS-CoV-2 infection.

Results: A total of 1518 patients were included, and 58% (n = 877) reported ≥1 SARS-CoV-2 infections. When assessing self-reported prevalence of post-COVID symptoms, 13.9% (122/877) linked their symptoms to a previous infection. Patients with a previous infection showed higher prevalence of symptoms than those without (56.2%, 43.9%; P < 0.001), and higher prevalence of fatigue (42%, 32%; P < 0.001). After adjusting for potential risk factors, previous infection was associated with symptoms (OR: 1.53; 95% CI: 1.23-1.91; P < 0.001), and fatigue (OR: 1.31; 95% CI: 1.04-1.64; P = 0.021). Subanalysis showed an association between self-reported COVID-19 severity and symptoms, while presumed SARS-CoV-2 variant (based on date of reported infection) and number of infections were not associated.

Conclusion: The self-reported prevalence of general health symptoms, particularly fatigue, is significantly higher in IMID patients with a previous SARS-CoV-2 infection. The cause of this increase requires further investigation and might provide insights into the pathogenesis of post-COVID, both relevant for IMID patients as well as the general population.
