Clinical Scorecard: Relationship Between Blood Urea Nitrogen to Albumin Ratio and Cerebral Small Vessel Disease Alongside Ischemic Imaging Indicators: A Cross-Sectional Analysis

At a Glance

CategoryDetail
ConditionCerebral Small Vessel Disease (CSVD)
Key MechanismsAssociation of blood urea nitrogen to albumin ratio (BAR) with ischemic neuroimaging markers.
Target PopulationAdults aged 30 to 85 years, including patients with and without CSVD.
Care SettingNeurology Department, The First Hospital of Quanzhou Affiliated to Fujian Medical University.

Key Highlights

  • BAR positively associated with CSVD and ischemic markers (WMH, EPVS).
  • No significant association found between BAR and lacunes.
  • Higher BAR quantiles correlate with increased risk of CSVD.
  • BAR serves as a potential novel biomarker for CSVD.
  • Sensitivity analyses confirm robustness of associations across kidney function levels.

Guideline-Based Recommendations

Diagnosis

  • Utilize neuroimaging for CSVD diagnosis.
  • Consider BAR as a complementary biomarker for early identification.

Management

  • Further investigation into BAR's role in risk stratification for CSVD.

Monitoring & Follow-up

  • Monitor BAR levels alongside kidney function and systemic inflammation markers.

Risks

  • Increased risk of CSVD with higher BAR levels.

Patient & Prescribing Data

762 participants, including 452 with CSVD and 310 controls.

BAR may guide treatment strategies and monitoring in CSVD patients.

Clinical Best Practices

  • Incorporate BAR assessment in routine evaluations for patients at risk of CSVD.
  • Use BAR in conjunction with traditional neuroimaging techniques.
