Abstract:
Rheumatoid arthritis (RA) increases the susceptibility to a variety of infections that are often difficult to diagnose and can be asymptomatic or symptoms are atypical. Usually, this is a great challenge for rheumatologists, because it is difficult to distinguish infection and aseptic inflammation at an early stage. Prompt diagnosis and treatment of bacterial infections in immunosuppressed individuals is critical for clinicians, and early exclusion of infection allows for specific treatment of inflammatory diseases and avoids the unnecessary use of antibiotics. However, for patients with clinically suspected infection, traditional laboratory markers are not specific for bacterial infection and cannot be used to distinguish outbreaks from infections. Therefore, new infection markers that can distinguish infection from underlying disease are urgently needed for clinical practice. Here, we review the novel biomarkers in RA patients with infection. These biomarkers include presepsin, serology and haematology, as well as neutrophils, T cells, and natural killer cells. Meanwhile, we discuss meaningful biomarkers that distinguish infection from inflammation and develop novel biomarkers for clinical applications, allowing clinicians to make better decisions when diagnosing and treating RA.
Insights
Diagnosing infections in rheumatoid arthritis (RA) patients is challenging due to atypical symptoms. Novel biomarkers like presepsin and immune cell analysis offer improved accuracy in distinguishing infection from inflammation, guiding treatment decisions.
Area of Science:
- Immunology
- Rheumatology
- Infectious Diseases
Background:
- Rheumatoid arthritis (RA) compromises immune function, increasing infection susceptibility.
- Differentiating infection from aseptic inflammation in RA patients is clinically challenging.
- Current diagnostic markers lack specificity for bacterial infections in immunosuppressed individuals.
Purpose of the Study:
- To review novel biomarkers for identifying infections in rheumatoid arthritis (RA) patients.
- To discuss biomarkers capable of distinguishing infection from inflammation.
- To highlight potential biomarkers for improved clinical decision-making in RA management.
Main Methods:
- Literature review of novel biomarkers in RA patients with infection.
- Analysis of biomarkers including presepsin, serology, haematology, neutrophils, T cells, and natural killer cells.
- Discussion of biomarkers differentiating infection from inflammation.
Main Results:
- Several novel biomarkers, including presepsin and immune cell profiles, show promise in identifying infections in RA.
- These biomarkers offer potential to differentiate between infection and aseptic inflammation.
- Current traditional markers are insufficient for accurate diagnosis in this population.
Conclusions:
- Novel biomarkers are crucial for accurate and timely diagnosis of infections in RA patients.
- Effective differentiation between infection and inflammation aids in appropriate treatment strategies.
- Further development and validation of these biomarkers will enhance clinical practice for RA management.
