Insights

Elevated serum Cystatin C (Cys C) levels are linked to a higher risk of depression after intracranial hemorrhage (ICH). Cys C may serve as a biomarker for predicting post-ICH depression.

Area of Science:

  • Neuroscience
  • Biochemistry
  • Clinical Medicine

Background:

  • Cystatins, including Cystatin C (Cys C), play roles in nervous system health and injury.
  • Cys C has been implicated in brain injury and inflammation.
  • Understanding factors predicting post-intracranial hemorrhage (ICH) depression is crucial.

Purpose of the Study:

  • To investigate the association between serum Cys C levels and the development of depression after ICH.
  • To evaluate Cys C as a potential biomarker for post-ICH depression.

Main Methods:

  • A cohort of 337 ICH patients were recruited and followed for three months.
  • Post-stroke depression (PSD) was diagnosed using DSM-IV criteria and the HAMD scale.
  • Serum Cys C levels were measured within 24 hours of admission.

Main Results:

  • 93 patients (27.6%) developed depression three months post-ICH.
  • Depressed patients exhibited significantly higher Cys C levels compared to non-depressed patients (1.32 vs 1.01, p<0.001).
  • Higher Cys C levels were independently associated with ICH-related depression (OR=3.195). A Cys C cut-off of 0.730 showed 84.5% sensitivity and 88.4% specificity (AUC=0.880).

Conclusions:

  • Elevated serum Cys C concentrations are independently associated with depression three months after ICH.
  • Cys C levels measured at admission may serve as a predictive biomarker for post-ICH depression.
