OBJECTIVES: To explore characteristics and treatment of patients with rheumatoid arthritis (RA) with invasive fungal infections (IFIs) and to describe infection details and outcome.
METHODS: IFIs reported to the German RABBIT (Rheumatoid Arthritis: Observation of Biologic Therapy) register between May 2001 and December 2023 were analysed using a two-stage approach. First, a detailed case description, including a comparison of cases by infection outcome, was conducted using routine register data and hospital discharge letters. Second, a multivariable time-dependent Cox regression model was fitted to analyse associations with IFI development using routine register data only.
RESULTS: Among 22 535 patients with RA, 69 IFIs occurred (incidence rate: 0.65/1000 patient-years), with a case fatality of 35% (n=24). Causative pathogens were Pneumocystis jirovecii (35%), Candida spp (33%) and Aspergillus spp (13%).Patients with IFIs were on average 65.4 years old; 54% were female, 80% ever-smokers, 84% glucocorticoid (GC) users and 91% had any infection-risk associated comorbidity at hospitalisation. IFI development was associated with older age (HR 1.36 per 10 years (95% CI 1.05 to 1.76)), male sex (HR 1.92 (95% CI 1.14 to 3.21)), ever-smoking (HR 2.43 (95% CI 1.35 to 4.37)), cardiovascular disease (HR 3.03 (95% CI 1.80 to 5.10)), chronic lung disease (HR 2.09 (95% CI 1.21 to 3.61)), other autoimmune disease (HR 2.11 (95% CI 1.10 to 4.07)), and the use of GCs (HR 1.17 (95% CI 1.11 to 1.22)).
CONCLUSION: In patients with RA, IFIs are rare but life-threatening. They occur particularly in patients who are predisposed to infection due to relevant comorbidities, a history of smoking or both. Except for GC use, the overall impact of targeted RA treatment on the risk of IFI appears to be less relevant than that of multimorbidity.
