TOPLINE:
METHODOLOGY:
- Patients with RA who have extra-articular manifestations such as ILD are highly susceptible to infections, but information on the types of infections, risk factors, and associations of infections with hospitalization and mortality is limited.
- This prospective multicenter cohort study evaluated infections in a cohort of 148 patients with RA-ILD (average age, 70 years; 57% women) recruited from 11 university hospitals in Spain between March 2015 and March 2023.
- Joint, lung, and any infection-related variables were evaluated using clinical and laboratory evaluations at baseline and selected time points till the end of the follow-up period (mean, 56.7 months).
- Researchers also investigated the common infectious sites, the etiology of the infection, vaccination status, variables associated with lung function, and clinical-therapeutic variables associated with RA.
TAKEAWAY:
- During the follow-up period, almost all (96%) patients had at least one infection, with the median time to first infection being 21.2 months and 65% of the deaths being directly related to infections.
- Respiratory infections were the most common first infections (74%) and led to death in 80% of the patients. Urinary tract (9.9%) and skin and soft tissue (9.1%) infections were the second and third most common first infections, respectively.
- Most infections were caused by SARS-CoV-2 (33.5%), Streptococcus pneumoniae (11.9%), Escherichia coli (11.9%), and Pseudomonas aeruginosa (11.1%), with mortality at 25.8% for SARS-CoV-2, 12.9% for P aeruginosa (12.9%), and 9.6% for pneumococci (9.6%).
- Increased age, disease activity, and the use of corticosteroids were associated with an elevated risk for infection and mortality in patients with RA-ILD.
IN PRACTICE:
“Our results demonstrate a high occurrence of serious infections among these patients, occurring early, recurring frequently, and proving fatal in 65% of cases,” the authors wrote.
SOURCE:
This study was led by Natalia Mena-Vázquez, MD, PhD, from Instituto de Investigación Biomédica de Málaga-Plataforma Bionand, Málaga, Spain, and published online March 27 in Frontiers in Immunology.
LIMITATIONS:
The findings of this study have been affected by the COVID-19 pandemic. The lack of a control group also limited the ability of this study to establish any causal relationships between ILD and the clinical outcomes analyzed.
DISCLOSURE:
This study was supported by Redes de Investigación Cooperativa Orientadas a Resultados en Salud and Fundación Andaluza de Reumatología. The authors declared having no conflicts of interest.
