Admission serum creatinine in non-hemodialysis-dependent patients with spontaneous supratentorial intracerebral hemorrhage: Is it a prognosticator?

Abstract

IntroductionSpontaneous intracerebral hemorrhage (ICH) carries a high mortality rate, with end-stage renal disease (ESRD) and hemodialysis being risk factors for early mortality. However, the role of admission serum creatinine in ICH prognosis remains unclear. This study aimed to analyze the correlation between admission serum creatinine levels and short-term ICH prognosis in non-hemodialysis-dependent patients. MethodsThis retrospective study analyzed 296 adult patients admitted with spontaneous supratentorial ICH. Demographic, clinical, and radiographic data were collected, including admission serum creatinine levels. The primary outcomes were mortality and unfavorable outcomes, defined as Modified Rankin Scale scores of 4–6. Univariate or multivariate analysis was performed to examine the association between admission serum creatinine levels and ICH prognosis, with and without the inclusion of maintenance hemodialysis patients. ResultsAmong all patients, elevated admission serum creatinine levels were significantly associated with increased mortality (OR = 1.39, 95% CI: 1.21–1.59, P < 0.01). However, this association disappeared when excluding patients undergoing maintenance hemodialysis (OR = 0.95, 95% CI: 0.53–1.69, P = 0.86). No significant association was found between admission serum creatinine levels and unfavorable outcomes. Other well-established prognostic factors, such as age and admission GCS, demonstrated significant associations with both mortality and unfavorable outcomes in multivariate analysis. ConclusionAdmission serum creatinine appears to have limited prognostic value in non-hemodialysis-dependent patients with spontaneous supratentorial ICH. Our findings suggest that the relationship between renal function and ICH prognosis is complex and may be influenced by factors such as comorbidities and maintenance hemodialysis.
