Summary
Short telomere length (TL) testing is crucial for interstitial lung disease (ILD) patients, impacting transplant decisions and care. Standardized pathways are needed for its effective integration into clinical practice.
Area of Science:
- Pulmonology
- Genetics
- Transplant Medicine
Background:
- Short telomeres are a primary inherited risk factor for fibrotic interstitial lung disease (ILD).
- Short telomeres correlate with ILD progression, complications, and treatment toxicity.
- The International Society for Heart and Lung Transplantation (ISHLT) consensus highlights telomere length (TL) testing in lung transplant evaluation.
Purpose of the Study:
- To explore the practical implications of the ISHLT consensus on TL testing for the broader ILD population.
- To address the challenges and propose strategies for integrating TL testing into ILD and transplant care.
- To guide clinicians on the application of TL testing across the ILD-to-transplant continuum.
Main Methods:
- Perspective piece analyzing the ISHLT consensus statement.
- Discussion of clinical realities and implementation challenges.
- Proposal for a research agenda to support TL testing integration.
Main Results:
- TL testing can inform critical clinical decisions like risk stratification and transplant planning.
- Current implementation is hindered by a lack of standardized clinical pathways.
- Evidence-based strategies are required for scalable and equitable integration of TL testing.
Conclusions:
- TL testing holds significant potential to improve outcomes for ILD patients.
- Standardized clinical pathways are essential for routine adoption of TL testing.
- Responsible implementation is key to realizing the benefits of TL testing in ILD and transplant care.
