Object Clazosentan therapy after aneurysmal subarachnoid hemorrhage (SAH) has been found to be effective in reducing the incidence of vasospasm in randomized controlled trials. However, while vasospasm-related morbidity, including delayed ischemic neurological deficits (DINDs) and delayed cerebral infarctions, was consistently decreased, statistical significance was not demonstrated and outcomes were not affected by clazosentan treatment. The objective of this meta-analysis was to determine whether clazosentan treatment after aneurysmal SAH significantly reduced the incidence of DINDs and delayed cerebral infarctions and improved outcomes. Methods All randomized controlled trials investigating the effect of clazosentan were retrieved via searches with sensitive and specific terms. Six variables were abstracted after the assessment of the methodological quality of the trials. Analyses were performed following the method guidelines of the Cochrane Back Review Group. Results Four randomized, placebo-controlled trials met eligibility criteria, enrolling a total of 2181 patients. The meta-analysis demonstrated a significant decrease in the incidence of DINDs (relative risk [RR] 0.76 [95% CI 0.62–0.92]) and delayed cerebral infarction (RR 0.79 [95% CI 0.63–1.00]) in patients treated with clazosentan after aneurysmal SAH. However, this treatment regimen was not shown to outcomes including functional outcomes measured by Glasgow Outcome Scale-Extended (RR 1.12 [95% CI 0.96–1.30]) or mortality (RR 1.02 [95%CI 0.70–1.49]). Adverse events, including pulmonary complications, anemia, and hypotension, were all significantly increased in patients who received clazosentan therapy. Conclusions The results of the present meta-analysis show that treatment with clazosentan after aneurysmal SAH significantly reduced the incidence of the vasospasm-related DINDs and delayed cerebral infarctions, but did not improve poor neurological outcomes in patients with aneurysmal SAH. Further study is required to elucidate the dissociation between vasospasm-related morbidity and outcomes.

Abstract Background: Tranexamic acid, as a traditional hemostatic agent, is commonly applied in the treatment or prevention of excessive blood loss. However, the role of tranexamic acid in promoting good clinical outcomes, reducing mortality, and the risk of experiencing adverse events during the therapeutic process of aneurysmal subarachnoid hemorrhage remains unclear.Methods: In strict accordance with the inclusion and exclusion criteria, the Cochrane Library, Embase, Web of Science, and PubMed were retrieved for randomized-controlled trials (from 1980 to 2021). Statistical analysis was performed using STATA 16.0 and RevMan 5.3. In addition, the fixed-effect model (M-H method) and effect size RR (95% CI) were used as a pooled measure to combine the heterogeneous data. We also performed post hoc sensitivity analysis and subgroup analysis to evaluate each outcome with low heterogeneity.Results: Meta-analysis revealed that although tranexamic acid was related to less rebleeding (RR = 0.72; 95% CI 0.59-0.87; P = 0.0008), it might have no effect on good clinical outcome or mortality (RR = 0.98; 95% CI 0.92-1.04; P = 0.51; RR = 1.01; 95% CI 0.88-1.15; P = 0.91). Tranexamic acid was associated with increased hydrocephalus (RR = 1.13; 95% CI 1.02-1.24; P = 0.02), delayed cerebral ischemia (RR = 1.70; 95% CI 1.34-2.16; P < 0.0001) and seizure (RR = 1.46; 95% CI 1.00-2.14; P = 0.05). The incidence of thromboembolic complications was identical in both groups (RR = 0.91; 95% CI 0.63-1.31; P = 0.62), and there were significant drug-related overall adverse events (RR = 1.21; 95% CI 1.11- 1.32; P < 0.0001).Conclusions: These findings indicate that the routine use of TXA is not suggested for patients with aneurysmal subarachnoid hemorrhage.
