Key result

Serial measurement of microbial cell-free DNA in 16 patients showed prolonged persistence post-extraction in definite CIEDI and rapid decline in possible CIEDI, potentially enhancing diagnosis.

Why the study?

Does serial measurement of quantitative microbial cell-free DNA (mcfDNA) enhance diagnostic accuracy in patients with staphylococcal cardiac implantable electronic device infection (CIEDI)?

Key Points

To assess the diagnostic accuracy and clinical utility of quantitative microbial cell-free DNA (mcfDNA) kinetics in suspected staphylococcal cardiac implantable electronic device infections (CIEDI).
Analyzed serial plasma mcfDNA levels before and after device removal in a cohort of 16 patients presenting with suspected staphylococcal CIEDI.
Stratified patients into clinical subgroups classified as "definite" (N=11) or "possible" (N=5) CIEDI to evaluate post-extraction biomarker clearance.
Patients with "definite" CIEDI exhibited prolonged persistence of mcfDNA in plasma following device extraction.
Patients with "possible" CIEDI showed rapid post-extraction decline of mcfDNA, highlighting potential utility in preventing unnecessary surgical extractions and prolonged antibiotic regimens.

Implication

Serial mcfDNA measurements may enhance diagnostic accuracy and potentially spare some patients from unnecessary device extraction and prolonged therapy in suspected CIEDI.

Abstract

We read with great interest the study by Karchmer et al. [1], which explored the role of quantitative microbial cell-free DNA (mcfDNA) as a biomarker in diagnosing and managing staphylococcal cardiac implantable electronic device infection (CIEDI).The authors serially measured mcfDNA in 11 patients with "definite" and five with "possible" CIEDI before and after device extraction.They observed prolonged mcfDNA persistence post-extraction in patients with "definite" CIEDI while rapidly declined in "possible" CIEDI, suggesting that serial mcfDNA measurements could enhance diagnostic accuracy, as well as potentially spare some patients from unnecessary device extraction, prolonged hospitalization and extended antibiotic therapy.

Chesdachai et al. (2025) conducted a letter in Staphylococcal cardiac implantable electronic device infection (CIEDI) (n=16). Serial measurement of quantitative microbial cell-free DNA (mcfDNA) was evaluated on mcfDNA persistence post-extraction. Serial measurement of microbial cell-free DNA in 16 patients showed prolonged persistence post-extraction in definite CIEDI and rapid decline in possible CIEDI, potentially enhancing diagnosis.
