Cerebrospinal Fluid Human Neutrophil Peptides 1–3: A Potential Prognostic Marker in Intracerebral Hemorrhage

<b><i>Background:</i></b> This study aims to investigate whether elevated human neutrophil peptides 1-3 (HNP 1-3) levels in cerebrospinal fluid (CSF) are associated with disease severity and clinical outcomes in patients with intracerebral hemorrhage (ICH). <b><i>Materials and Methods:</i></b> HNP 1-3 levels were measured in CSF samples collected within 3 days after hemorrhage onset in ICH patients and control subjects. <b><i>Results:</i></b> HNP 1-3 levels were significantly higher in ICH patients with moderate-severe coma and hematoma volume >30 mL group. Univariate and multivariate logistic regression analyses demonstrated that CSF HNP 1-3 levels were associated with unfavorable outcomes. Receiver operating characteristic analysis revealed that CSF HNP 1-3 concentrations >466.95 ng/mL could distinguish ICH patients at risk for an unfavorable prognosis. <b><i>Conclusions:</i></b> HNP 1-3 exhibit satisfactory diagnostic efficiency for predicting the prognosis of ICH patients.
