Researchers are exploring circulating DNA and RNA for diagnosing acute conditions like trauma and stroke. Elevated plasma DNA levels correlate with injury severity and stroke prognosis, paving the way for new diagnostic markers.

Area of Science:

  • Molecular diagnostics
  • Biomarker discovery
  • Clinical chemistry

Background:

  • Plasma DNA and RNA analysis is emerging for disease diagnosis, prognostication, and monitoring.
  • Cell death is a suspected source of circulating nucleic acids.
  • Elevated plasma DNA/RNA is observed in acute conditions like trauma and stroke.

Purpose of the Study:

  • To review the diagnostic potential of circulating nucleic acids.
  • To highlight the correlation between plasma DNA levels and disease severity/prognosis.

Main Methods:

  • Analysis of existing research on plasma DNA and RNA in clinical settings.
  • Correlation studies examining plasma DNA concentrations against injury severity and stroke prognostic indices.

Main Results:

  • Increased plasma DNA and RNA detected in patients with acute traumatic injuries.
  • Plasma DNA elevation positively correlates with injury severity.
  • Plasma DNA concentrations correlate with prognostic indicators in acute stroke patients.

Conclusions:

  • Circulating nucleic acids, particularly DNA, show promise as biomarkers for acute pathologies.
  • Plasma RNA detection may offer new avenues for evaluating acute conditions.
  • Further development of plasma RNA-based markers is anticipated for acute care diagnostics.
