RESUMO

INTRODUCTION: Door-to-needle time (DNT) is an established predictor of outcome in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT). Several strategies have been proposed to streamline in-hospital pathways, among which treatment at CT/MR bed. AIM: To explore the impact of treatment at CT/MR bed, here defined as imaging area (IA), on functional outcome in stroke patients treated with IVT alone. METHODS: All AIS patients treated with IVT alone at our center in 2020, 2021, and 2022 were included. Patients with any previous disability were excluded. The cohort was divided into two groups, depending on the treatment site. One group received IVT at IA, the other at emergency room or stroke unit (non-IA). Regression analysis assessed the association between treatment site and 3-month outcome. RESULTS: A total of 327 patients who received IVT alone were included in the analysis. One hundred thirty-three (40.7%) were in the IA group and 194 (59.3%) in the non-IA group. The groups showed similar baseline characteristics. In the IA group, DNT was 45 min shorter. Despite similar rates of functional independence (mRS 0-2), the IA group showed higher rates of excellent outcome (mRS 0-1) compared to the non-IA group (60.1% vs 42.8%, p<0.01). Immediate treatment at IA was independently associated to excellent outcome (OR 1.78 [1.03-3.08]). CONCLUSIONS: Thrombolytic treatment at IA lowers DNT and is an independent predictor of excellent outcome after AIS. Our study emphasizes the importance of immediate thrombolytic treatment at IA, soon after radiological eligibility is confirmed. Immediate treatment at IA should be a standard-of-care for AIS.

RESUMO

Sixty-six patients with possible or probable MSA (multiple system atrophy) cerebellar type, personally observed between 2006 and 2018 were retrospectively reviewed. The time point of data collection was January 1, 2019. Forty-nine patients lost independent walking after a median time of 5 years (95% C. I. 4-6). Thirty-two patients were confined to wheelchair after a median time of 7 years (95% C. I. 7-8). Twenty-seven patients were deceased after a median time of 9 years (95% C. I. 8-10). A later onset predicted an earlier loss of independent walking (HR 1.07; 95% C.I. 1.03-1.11; p = 0.001). Higher UMSARS score predicted shorter time to loss of independent walking (HR 1.04; 95% C.I. 1.02-1.06; p = 0.001) and to wheelchair (HR 1.03; 95% C.I. 1.01-1.06; p = 0.021). No predictor of time to death was found.

RESUMO

Rasmussen's encephalitis (RE) is an immune-mediated disease, typically affecting a single cerebral hemisphere. Intractable epilepsy, hemiplegia and cognitive decline represent the clinical features; movement disorders have rarely been described. We report a case of adult-onset RE which developed hemiparkinsonism after an extraordinarily long prodromal period; to date, this is the first description of parkinsonism in RE. The association between cortical symptoms and extrapyramidal features evokes a clinical suspect of corticobasal syndrome (CBS); our patient satisfies the diagnostic criteria for possible CBS. Clinical and neuro-radiological reasons might further explain why RE accompanied by extrapyramidal signs may present as a CBS.

RESUMO

INTRODUCTION: Endovascular thrombectomy (EVT) is the standard of care for selected patients with acute ischemic stroke (AIS) and large vessel occlusion (LVO), associated with intravenous thrombolysis, when indicated. While many studies focused on pre-hospital and in-hospital pathways, only few analyzed the relationship between groin-to-recanalization (GTR) time and functional outcome. AIM: To explore whether GTR time is an independent predictor of outcome in patients undergoing EVT. METHODS: All patients with anterior circulation stroke treated with EVT at a high-volume center from January 2021 to December 2023 were included. The cohort was divided into two groups according to GTR time shorter or longer than 30 min. Regression analysis assessed the association between GTR time and 3-month good outcome, defined as modified Rankin Scale 0-2. RESULTS: The study included 419 patients. The groups had similar baseline characteristics and similar onset to recanalization (OTR) time. Regression analysis showed shorter GTR time is an independent predictor of favorable outcome (OR 2.49 [95% CI 1.26-4.94]). Age, baseline NIHSS, ASPECT score and bridging IVT were also found to be independently associated with outcome. DISCUSSION AND CONCLUSIONS: Our study showed GTR time is an independent predictor of good outcome in patients undergoing EVT with similar OTR time, emphasizing procedural time as a key prognostic factor, even greater than other well-known pre-hospital and in-hospital time-dependent variables. These findings may raise the issue of developing alternative approaches or early "rescue" strategies for complicated procedures.

RESUMO

LRRK2 gene mutations (PARK8) are a common cause of genetic Parkinson disease (PD). G2019S, the most frequent mutation, is responsible for both familial and sporadic cases of PD. The clinical picture is usually indistinguishable from that observed in idiopathic PD; however, a wide range of clinical presentations and pathological findings has been described. Restless leg syndrome (RLS) is a disabling sleep-related sensorimotor disorder whose pathogenesis is likely related to dopaminergic dysfunction. We report a 77-year-old woman with RLS and familial history of parkinsonism. The father, one sister, two cousins and one uncle were affected by PD. The proband and her sister were analyzed for mutations in LRRK2 gene and resulted to carry one heterozygous G2019S mutation in LRRK2 gene. The association between RLS and LRRK2 gene mutation may be casual, but it can hypothesized that RLS is a possible phenotypic presentation in PARK8.

RESUMO

Endovascular thrombectomy is the standard treatment in selected patients with acute ischemic stroke and large vessel occlusion, but continuous improvement in angiographic and clinical outcome is still needed. Intra-arterial thrombolysis has been tested as a possible rescue tool in unsuccessful thrombectomy, or as an adjuvant therapy after the endovascular procedure, to pursue complete recanalization. Here we present a case series analysis of intra-arterial alteplase administration (5 mg bolus, repeated up to 15 mg if Thrombolysis in Cerebral Infarction (TICI) scale ≥2c is not achieved) in 15 consecutive anterior circulation stroke patients after unsuccessful thrombectomy, defined as TICI score ≤2b after at least 3 passes or if unsuitable for further endovascular attempts, with the aim of improving recanalization. An improvement of final TICI score was achieved in 10 of 15 patients (66.7%). TICI score ≥2c was achieved after 5 mg intra-arterial tissue plasminogen activator (iaTPA) in 4 patients, and after 10 mg iaTPA in 5 cases. Six of 15 patients received 15 mg iaTPA: 1 of 6 showed angiographical improvement. A major effect of intra-arterial alteplase was observed for distally migrated emboli. None of the patients experienced any symptomatic hemorrhagic transformation or other major bleeding. Our report shows, in a very small cohort, a high rate of final TICI score improvement, encouraging the development of randomized controlled trials of rescue intra-arterial thrombolysis in patients with suboptimal angiographic results after mechanical thrombectomy.

RESUMO

BACKGROUND: Several concerns exist on the immunogenicity of SARS-CoV-2 vaccines in multiple sclerosis (MS) subjects due to their immunomodulating disease modifying therapies (DMTs). Here we report a comparison of the humoral response to BNT162b2-mRNA coronavirus (COVID)-19 vaccine and the immunological phenotype in a cohort of 125 MS subjects undergoing different DMTs, with no history of SARS-CoV-2 infection. METHODS: We collected serum and blood samples at the first day of vaccine (T0) and 21 days after the second vaccine dose (T1) from 125 MS subjects, undergoing eight different DMTs. Sera were tested using the Elecsys anti-SARS-CoV-2-IgG assay for the detection of IgG antibodies to SARS-CoV-2 spike protein. The anti-spike IgG titres from MS subjects were compared with 24 age- and sex-matched healthy controls (HC). Percentage and absolute number of B and T lymphocytes were evaluated by cytofluorimetric analysis in the same study cohort. RESULTS: When compared with SARS-CoV-2 IgG levels in HC (n = 24, median 1089 (IQR 652.5-1625) U/mL), we observed an increased secretion of SARS-CoV-2 IgG in interferon-beta 1a (IFN)-treated MS subjects (n = 22, median 1916 (IQR 1024-2879) U/mL) and an impaired humoral response in MS subjects undergoing cladribine (CLAD) (n = 10, median 396.9 (IQR 37.52-790.9) U/mL), fingolimod (FTY) (n = 19, median 7.9 (IQR 4.8-147.6) U/mL) and ocrelizumab (OCRE) (n = 15, median 0.67 (IQR 0.4-5.9) U/mL) treatment. Moreover, analysis of geometric mean titre ratio (GMTR) between different DMT's groups of MS subjects revealed that, when compared with IFN-treated MS subjects, intrinsic antibody production was impaired in teriflunomide (TERI)-, natalizumab (NAT)-, CLAD-, FTY- and OCRE-, while preserved in DMF- and GA-treated MS subjects. CONCLUSION: Humoral response to BNT162b2-mRNA-vaccine was increased in IFN-treated MS subjects while clearly blunted in those under CLAD, FTY and OCRE treatment. This suggests that the DMTs could have a key role in the protection from SARS-CoV-2 related disease and complication in MS subjects, underlying a novel aspect that should be considered in the selection of the most appropriate therapy under COVID-19 pandemic.

RESUMO

BACKGROUND: The so-called "vaccine hesitancy" still represents a common phenomenon that undermines the effectiveness of vaccination campaigns. In 2020, the Italian Medicines Agency recommended to bring forward the flu vaccination campaign, whose importance was also emphasized for patients with Multiple Sclerosis (MS). We aimed to assess vaccination behavior in patients with MS to prepare for the upcoming SARS-CoV-2 vaccination challenge. METHODS: This is an observational study carried out in one MS clinical Centre that enrolled all MS patients who were eligible for any of the flu vaccines recommended by the Italian medicines Agency. RESULTS: 194 patients were enrolled. Patients' mean age was 43.9 years and 66% were female. Comorbidities, mainly represented by non-autoimmune diseases, were identified in 52% of patients. Almost all patients were receiving a DMT during the study period, mainly dimethyl fumarate, natalizumab, teriflunomide, and interferon. Out of 194 patients, 58.2% accepted to be vaccinated. No statistically significant differences were found, except for the use of natalizumab, which was higher among vaccinated patients. CONCLUSION: The results of our study emphasize the importance of education and communication campaigns addressed both to healthcare providers and patients with MS, especially considering that MS patients are currently receiving COVID-19 vaccinations.
