RESUMEN
BACKGROUND AND PURPOSE: Patients with adenosine deaminase 2 (ADA2) deficiency can present with various neurological manifestations due to vasculopathies and autoinflammation. These include ischaemic and hemorrhagic stroke, but less clearly defined neurological symptoms have also been reported. METHODS: In this cohort study, patients with confirmed ADA2 deficiency from seven university hospitals in the Netherlands were included. The frequency and recurrence rates of neurological manifestations before and after initiation of tumor necrosis factor α (TNF-α) inhibiting therapy were analyzed. RESULTS: Twenty-nine patients were included with a median age at presentation of 5 years (interquartile range 1-17). Neurological manifestations occurred in 19/29 (66%) patients and were the presenting symptom in 9/29 (31%) patients. Transient ischaemic attack (TIA)/ischaemic stroke occurred in 12/29 (41%) patients and was the presenting symptom in 8/29 (28%) patients. In total, 25 TIAs/ischaemic strokes occurred in 12 patients, one after initiation of TNF-α inhibiting therapy and one whilst switching between TNF-α inhibitors. None was large-vessel occlusion stroke. Two hemorrhagic strokes occurred: one aneurysmatic subarachnoid hemorrhage and one spontaneous intracerebral hemorrhage. Most neurological symptoms, including cranial nerve deficits, vertigo, ataxia and seizures, were caused by TIAs/ischaemic strokes and seldom recurred after initiation of TNF-α inhibiting therapy. CONCLUSIONS: Neurological manifestations, especially TIA/ischaemic stroke, are common in patients with ADA2 deficiency and frequently are the presenting symptom. Because it is a treatable cause of young stroke, for which antiplatelet and anticoagulant therapy are considered contraindicated, awareness amongst neurologists and pediatricians is important. Screening for ADA2 deficiency in young patients with small-vessel ischaemic stroke without an identified cause should be considered.

BACKGROUND AND OBJECTIVES: To explore clinical and safety outcomes of patients with acute ischemic stroke (AIS) and active cancer after endovascular treatment (EVT). METHODS: Using data from the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN) Registry, we compared patients with active cancer (defined as cancer diagnosed within 12 months before stroke, metastatic disease, or current cancer treatment) to patients without cancer. Outcomes were 90-day modified Rankin Scale (mRS) score, mortality, successful reperfusion (expanded Treatment in Cerebral Infarction score ≥2b), symptomatic intracranial hemorrhage (sICH), and recurrent stroke. Subgroup analyses were performed in patients with a prestroke mRS score of 0 or 1 and according to treatment setting (curative or palliative). Analyses were adjusted for prognostic variables. RESULTS: Of 2,583 patients who underwent EVT, 124 (4.8%) had active cancer. They more often had prestroke disability (mRS score ≥2: 34.1% vs 16.6%). The treatment setting was palliative in 25.3% of the patients. There was a shift toward worse functional outcome at 90 days in patients with active cancer (adjusted common odds ratio [acOR] 2.2, 95% confidence interval [CI] 1.5-3.2). At 90 days, patients with active cancer were less often independent (mRS score 0-2: 22.6% vs 42.0%, adjusted OR [aOR] 0.5, 95% CI 0.3-0.8) and more often dead (52.2% vs 26.5%, aOR 3.2, 95% CI 2.1-4.9). Successful reperfusion (67.8% vs 60.5%, aOR 1.4, 95% CI 1.0-2.1) and sICH rates (6.5% vs 5.9%, aOR 1.1, 95% CI 0.5-2.3) did not differ. Recurrent stroke within 90 days was more common in patients with active cancer (4.0% vs 1.3%, aOR 3.1, 95% CI 1.2-8.1). The sensitivity analysis of patients with a prestroke mRS score of 0 or 1 showed that patients with active cancer still had a worse outcome at 90 days (acOR 1.9, 95% CI 1.2-3.0). Patients with active cancer in a palliative treatment setting regained functional independence less often compared to patients in a curative setting (18.2% vs 32.1%), and mortality was higher (81.8% vs 39.3%). DISCUSSION: Despite similar technical success, patients with active cancer had significantly worse outcomes after EVT for AIS. Moreover, they had an increased risk of recurrent stroke. Nevertheless, about a quarter of the patients regained functional independence, and the risk of other complications, most notably sICH, was not increased. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that patients with active cancer undergoing EVT for AIS have worse functional outcomes at 90 days compared to those without active cancer.

Background and Purpose- Low blood pressure is uncommon in patients with acute ischemic stroke (AIS). We assessed the association between baseline low blood pressure and outcomes in patients with AIS. Methods- Post hoc analysis of the PASS (Preventive Antibiotics in Stroke Study). We compared patients with AIS and low (<10th percentile) baseline systolic blood pressure (SBP) to patients with normal SBP (≥10th percentile <185 mm Hg). The first SBP measured at the Emergency Department was used. Outcomes included in-hospital mortality, major complications <7 days of stroke onset, and functional outcome at 90 days (modified Rankin scale score). We used regression analysis to calculate (common) odds ratios and adjusted for predefined prognostic factors. Results- Two thousand one hundred twenty-four out of 2538 patients had AIS. The cutoff for low SBP was 130 mm Hg (n=212; range, 70-129 mm Hg). One thousand four hundred forty patients had a normal SBP (range, 130-184 mm Hg). Low SBP was associated with an increased risk of in-hospital mortality (8.0% versus 4.2%; adjusted odds ratio [aOR], 1.58; 95% CI, 1.13-2.21) and complications (16.0% versus 6.5%; aOR, 2.56; 95% CI, 1.60-4.10). Specifically, heart failure (2.4% versus 0.1%; aOR, 17.85; 95% CI, 3.36-94.86), gastrointestinal bleeding (1.9% versus 0.1%; aOR, 26.04; 95% CI, 2.83-239.30), and sepsis (3.3% versus 0.5%; aOR, 5.53; 95% CI, 1.84-16.67) were more common in patients with low SBP. Functional outcome at 90 days did not differ (shift towards worse outcome: adjusted common odds ratio, 1.24; 95% CI, 0.95-1.61). Conclusions- Whether it is cause or consequence, low SBP at presentation in patients with AIS was associated with an increased risk of in-hospital mortality and complications, specifically heart failure, gastrointestinal bleeding, and sepsis. Clinicians should be vigilant for potentially treatable complications. Clinical Trial Registration- URL: https://www.controlled-trials.com. Unique identifier: ISRCTN66140176.

BACKGROUND AND AIM: Alcohol intoxication can be a posterior circulation stroke mimic as they share symptoms such as dysarthria, gait disturbances and nystagmus. We describe alcohol intoxication as a stroke mimic and the frequency of acute alcohol intoxication among stroke patients. METHODS: Prospective observational single-center study (2014-2017, Haga Ziekenhuis, the Hague). In all patients older than 16 years presenting as possible acute stroke less than 6 hours of onset, blood ethanol was measured; greater than 0.1 blood alcohol concentration (BAC) was considered elevated. RESULTS: In total 974 patients were included: 60 (6%) had elevated blood ethanol (mean: 1.3 BAC). In 180 of 974 patients (18%) a stroke mimic was diagnosed: 12 were due to alcohol intoxication (1% of total cohort, 7% of stroke mimic, mean ethanol level: 2.2 BAC). Half of these patients denied or downplayed their alcohol consumption. Stroke and concurrent alcohol intoxication occurred in 38 of 794 strokes (5%, mean ethanol level: 1.1 BAC). Compared to other stroke patients, these 38 patients presented more often after working hours (mean 6.38pm versus 2.23pm) and received alteplase and endovascular therapy less often (24% versus 43%, P = .018 and 3% versus 10%, P = .241, respectively). CONCLUSIONS: Of all patients presenting as possible acute stroke, 6% also drank alcohol. 18% of the whole cohort was diagnosed with a stroke mimic. Acute alcohol intoxication as sole diagnosis was diagnosed in 1% of the total cohort and 7% of stroke mimics, 50% denied or downplayed their alcohol consumption. 5% of all stroke patients also drank alcohol, they were significantly less likely to receive alteplase or endovascular treatment.

BACKGROUND/AIMS: Patients with mild traumatic brain injury (mTBI) on anticoagulants have an increased risk of intracranial hemorrhage (ICH). However, consensus is lacking on whether to admit them after normal initial cranial CT. We evaluated the yield of 24-h neurological observation. METHODS: Retrospective multicenter study including adult patients admitted over a 5-year period with mTBI on anticoagulation [therapeutic dose heparin, direct oral anticoagulant, or vitamin K antagonist (VKA) with international normalized ratio (INR) ≥ 1.7] and reportedly normal cranial CT obtained within 24 h after trauma. Primary endpoint was symptomatic ICH within 24 h of injury. Literature on delayed ICH in patients with mTBI and anticoagulation use was reviewed. RESULTS: Of 17.643 mTBI patients, 905 met the inclusion criteria (median age 82 years). 97% used VKA (median INR 2.9). None developed delayed ICH within 24 h. Nine patients deteriorated neurologically due to ICH, four within 24 h (0.4%, 95% CI 0.1-1.2) and five on day 2, 18, 22, 36 and 52, respectively. In six patients, including all four that developed symptoms within 24 h, ICH was found upon reevaluation of initial imaging. The meta-analysis comprised of 9 studies with data from 2885 patients. The estimated pooled proportion of symptomatic delayed ICH or delayed diagnosis of ICH within 24 h was 0.2% (95% CI 0.0-0.5). CONCLUSIONS: Delayed (diagnosis of) ICH within 24 h is very rare in mTBI patients on anticoagulants after reportedly normal initial CT. Routine hospitalization of these patients seems unwarranted when the initial cranial CT is scrupulously evaluated.
