Dexamethasone in Patients with Spontaneous Intracerebral Hemorrhage: An Updated Meta-Analysis

<b><i>Background:</i></b> Spontaneous intracerebral hemorrhage (ICH) is a frequent cerebrovascular disorder and still associated with high mortality and poor clinical outcomes. The purpose of this review was to update a 15-year-old former meta-analysis on randomized clinical trials (RCTs) addressing the question of whether ICH patients treated with dexamethasone have better outcomes than controls. <b><i>Methods:</i></b> The electronic databases PubMed, SCOPUS, and Cochrane as well as web platforms on current clinical trials were searched for the years 1970–2020 without constriction on language. Data were extracted and outcomes were pooled for conventional and cumulative meta-analysis using a commercial software program (www.Meta-Analysis.com). <b><i>Results:</i></b> Finally, 7 RCTs were identified and analyzed including 248 participants in the dexamethasone groups and 242 in the control groups. Five studies showed a high risk of bias. The overall relative risk (RR) for death was 1.32 (95% confidence interval [CI] 0.99–1.76; <i>p</i> = 0.06) and did not differ significantly between the 2 groups. After exclusion of studies with high risk of bias, the RR for death was 1.37 (95% CI 0.54–3.42; <i>p</i> = 0.51). The RR for poor outcome did not differ significantly between the 2 groups analyzed for all included studies (RR = 0.69; 95% CI 0.47–1; <i>p</i> = 0.05) and after exclusion of studies with high risk of bias (RR = 0.7; 95% CI 0.45–1.08; <i>p</i> = 0.11). The RR for complications did not differ significantly including all studies (RR = 1.29; 95% CI 0.77–2.17; <i>p</i> = 0.34) and after exclusion of studies with high risk of bias (RR = 1.27; 95% CI 0.18–8.89; <i>p</i> = 0.81). The cumulative statistics delivered no other results; however, it pointed out fewer complications over time in the dexamethasone group. <b><i>Conclusion:</i></b> Clear evidence of a beneficial or negative effect of dexamethasone is still lacking. Modern RCTs or observational studies with propensity design are necessary to evaluate the efficacy and safety of treatment with dexamethasone in patients with ICH.

[Intracerebral hemorrhage related to anticoagulant therapy]

Intracerebral hemorrhage (ICH) is the most serious complication of oral anticoagulant therapy (OAT). The growing use of OAT has resulted in an increase of fatal ICH. The mortality rate is about 65%, and most of the surviving patients remain disabled. While improvements in the treatment of spontaneous ICH have recently been described, there are no internationally accepted guidelines for managing patients with OAT-ICH. Therefore, identifying effective treatments is essential for improving clinical outcome. This article reviews the epidemiology of OAT-ICH, its pathophysiology, and current treatment options and discusses open questions with particular respect to more recent pharmacological therapies.
