Graphical Abstract:


Objective: Erythropoietin (EPO) for treating acute ischemic stroke (AIS) has been investigated in many studies. However, the evidence was inconsistent. Thus, a systematic review and metaanalysis were performed to elucidate the role of EPO in treating patients with AIS.

Methods: Two electronic databases (PubMed and EMBASE) were used. 30-day NIHSS measures primary outcome while all-cause mortality in the follow up and 90-day Barthel Index were regarded as secondary outcome. Results are presented as relative risk (RR), standardized mean difference (SMD) and 95% confidence intervals (CI). We employed Stata software to perform the meta-analysis.

Results: Four randomized controlled trials (RCTs) involving 784 patients were contained in this metaanalysis. The total combined results on 30-day NIHSS were (SMD = -0.52, 95% CI: -1.39, 0.34) with random-effects model and sensitivity analysis showed a significant difference after excluding the Ehrenreich 2009 trial. The total combined secondary measured results were (RR=1.72, 95% CI: 1.10, 2.70) and (SMD = 0.01, 95% CI: -0.14, 0.16) for all-cause mortality and 90-day Barthel Index. In the subgroup analysis by using recombinant tissue plasminogen activator (rtPA) earlier, the rtPA group showed increased all-cause mortality with the result of (RR = 1.92, 95% CI: 1.04, 3.52), but not in non-rtPA group.

Conclusion: To our systematic review and meta-analysis, we didn’t recommend EPO administration for patients with AIS, especially with the combination of rtPA. Large RCTs are warranted to examine EPO efficacy in AIS patients in the future.
