Introduction Given the COVID19 pandemic, it is crucial to understand the underlying behavioral determinants of SARS-CoV-2 vaccine hesitancy in patients with autoimmune or inflammatory rheumatic diseases AIIRD. We aimed to analyze patterns of behaviors regarding SARS-CoV-2 vaccination in AIIRD patients, as a mean to identify pragmatic actions to increase vaccine coverage in this population. Methods Data of 1258 AIIRD patients were analyzed using univariate and multivariate logistic regression models, to identify variables associated independently with the willingness to get vaccinated against SARS-CoV-2. Subsets of patients showing similar behaviors towards SARS-CoV-2 vaccination were characterized using cluster analysis. Results Hierarchical cluster analysis identified 3 distinct clusters of AIIRD patients. Three predominant patients’ behavior towards SARS-COV-2 vaccination: ‘voluntary’, ‘hesitant’ and ‘suspicious’ were identified. While vaccine willingness was significantly different across the 3 clusters p< 0.0001, there was no difference regarding the fear to get COVID-19 p= 0.11, the presence of co-morbidities p= 0.23, the use of glucocorticoids p= 0.21 or the immunocompromised status p= 0.63. However, patients from cluster #3 ‘suspicious’ were significantly more concerned about vaccination, the use of a new vaccine technology, the lack of hindsight regarding COVID vaccination and potential financial links with pharmaceutical companies p< 0.0001 in all than in the other 2 clusters. Discussion Importantly, the differences between patients’ behaviors are not related to the fear of getting COVID-19 or to any state of frailty, but point out to specific concerns about vaccination. This study may serve as a basis for improved communication, to increase COVID-19 vaccine coverage in AIIRD patients.

Fatigue is a complex and multifactorial phenomenon which is often neglected by clinicians. The aim of this review was to analyze the impact, determinants and management of fatigue in patients with Systemic Lupus Erythematosus (SLE). Fatigue is one of the most prevalent symptoms in SLE, reported by 67% to 90% of patients. It is also described as the most bothersome symptom, considering that it may impair key aspects of health-related quality of life, while also leading to employment disability. It is a multifactorial phenomenon involving psychological factors, pain, lifestyle factors such as reduced physical activity, whereas the contribution of disease activity remains controversial. The management of fatigue in patients with SLE should rely upon a person-centered approach, with targeted interventions. Some pharmacological treatments used to control disease activity have demonstrated beneficial effects upon fatigue and non-pharmacological therapies such as psychological interventions, pain reduction and lifestyle changes, and each of these should be incorporated into fatigue management in SLE.
