Impact of Intravenous Human Albumin, Enteral Cilostazol, and Their Combined Use

Overview

This study evaluates the effects of intravenous human albumin, enteral cilostazol, and their combination on reducing delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH).

Background

Delayed cerebral ischemia (DCI) is a significant cause of morbidity and mortality following aneurysmal subarachnoid hemorrhage (aSAH). Current treatment options are limited, with oral nimodipine being the only agent proven to improve neurological outcomes.

Data Highlights

TreatmentMedian ARR vs Control (%)90% Simulation IntervalPrior-Predictive Probability of ARR > 0 (%)
Albumin9.1−3.3 to 18.189.8
Cilostazol18.111.0 to 25.499.9
Combination Therapy21.712.4 to 29.999.8

Key Findings

  • The median absolute risk reduction (ARR) for DCI was 9.1% for albumin, 18.1% for cilostazol, and 21.7% for combination therapy.
  • The incremental benefit of adding albumin to cilostazol was small and uncertain at 3.5%.
  • Simulation results indicate a high probability of cilostazol and combination therapy being effective in reducing DCI.
  • Sample sizes for trials would need to be substantial, with illustrative sizes of 343 for albumin and 49 for combination therapy.
  • Current evidence for cilostazol is stronger than for albumin based on previous studies.

Clinical Implications

Continued randomized evaluations are necessary to better understand the efficacy of these treatments and their potential interactions.

Conclusion

Further research is warranted to explore the effects of cilostazol and albumin in aSAH management.
