Statin Use

Background: The data on the relationship between statin use and clinical outcomes after intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) are in controversy.Objective: This systematic review and meta-analysis aimed to evaluate the safety and efficacy of statins administered prior to onset and during hospitalization in patients with AIS treated with IVT.Methods: We searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials from inception until June 8, 2021. Comparative studies investigating statin effect on intracranial hemorrhage (ICH), functional outcomes, and mortality in adults with AIS treated with IVT were screened. Random-effect meta-analyses of odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were performed. The protocol was registered in PROSPERO (CRD42021254919).Results: Twenty-two observational studies were included, which involved 17,554 patients. The pooled estimates showed that pre-stroke statin use was associated with a higher likelihood of symptomatic ICH (OR 1.31; 95% CI 1.07–1.59; p = 0.008) and any ICH (OR 1.21; 95% CI 1.03–1.43; p = 0.02). However, the pre-stroke statin use was not significantly associated with the 3-month mortality, 3-month favorable functional outcome (FFO, modified Rankin Scale [mRS] score 0–1), and 3-month functional independence (FI; mRS score 0–2). However, in-hospital statin use was associated with a reduced risk of symptomatic ICH (OR 0.46; 95% CI 0.21–1.00; p = 0.045), any ICH (OR 0.51; 95% CI 0.27–0.98; p = 0.04), and 3-month mortality (OR 0.42; 95% CI 0.29–0.62; p < 0.001) and an increased probability of 3-month FFO (OR 1.33; 95% CI 1.02–1.744; p = 0.04) and 3-month FI (OR 1.41; 95% C, 1.11–1.80; p = 0.005).Conclusions: The present systematic review and meta-analysis suggests that in-hospital statin use after IVT may be safe and may have a favorable impact on clinical outcomes, a finding not observed in studies restricted to patients with pre-stroke statin use.

OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

The Impact

Background. The impact of renal impairment (RI) on the outcomes of patients with acute ischemic stroke (AIS) treated with endovascular thrombectomy (EVT) was relatively limited and contradictory. We performed a systematic review and meta-analysis to investigate this. Aims. We registered a protocol on September 2020 and searched MEDLINE, EMBASE, and Google Scholar accordingly. RI was defined as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2. Predefined outcomes included functional independence (defined as a modified Rankin Scale of 0, 1, or 2) at 3 months, successful reperfusion, mortality, and symptomatic intracerebral hemorrhage (sICH). Summary of review. Eleven studies involving 3453 patients were included. For the unadjusted outcomes, RI was associated with fewer functional independence (odds ratio (OR), 0.49; 95% confidence interval (CI), 0.39–0.62) and higher mortality (OR, 2.55; 95% CI, 2.03–3.21). RI was not associated with successful reperfusion (OR, 0.80; 95% CI 0.63–1.00) and sICH (OR, 1.41; 95% CI, 0.95–2.10). For the adjusted outcomes, results derived from a multivariate meta-analysis were consistent with the respective unadjusted outcomes: functional independence (OR, 0.59; 95% CI, 0.45–0.77), mortality (OR, 2.23, 95% CI, 1.45–3.43), and sICH (OR, 1.34; 95% CI, 0.85–2.10). Conclusions. We presented the first systematic review to demonstrate that RI is associated with fewer functional independence and higher mortality. Future EVT studies should publish complete renal eGFR data to facilitate prognostic studies and permit eGFR to be analyzed in a continuous variable.
