Recomendaciones en el abordaje del hematoma intracerebral espontáneo durante la internación / Recommendations for the management of spontaneous intracerebral hemorrhage during hospitalization

Resumen El accidente cerebrovascular (ACV) constituye la principal causa de discapacidad de origen neuro- lógico en los adultos mayores a 40 años y la cuarta causa de muerte en Argentina. En los últimos diez años las publicaciones indexadas relacionadas al tratamiento del ACV isquémico fueron más numerosas que las de ACV hemorrágico. El objetivo de este material es proporcionar recomendaciones locales y actualiza- das del abordaje de pacientes con hematoma intraparenquimatoso espontáneo durante la internación. Para la redacción de este manuscrito se convocó a especialistas en esta enfermedad que conformaron grupos de trabajo. Se plantearon 10 tópicos centrales expresados como epidemiologia, atención inicial, imágenes, tratamiento de la presión arterial, reversión de antitrombóticos, indicación de cirugía, profilaxis anticonvulsivante, pronóstico, prevención de complicaciones y reinicio de antitrombóticos. De cada tópico se plantearon mediante preguntas PICO los interrogantes más frecuentes de la práctica diaria. Luego de una revisión sistemática de la literatura, se generaron recomendaciones evaluadas mediante sistema GRADE y consensuadas entre autores y pacientes.

Abstract Stroke is the leading cause of neurological disability in people over 40 years of age and the fourth leading cause of death in Argentina. In the last ten years, the indexed publications related to the treatment of ischemic stroke were more numerous than those of hemorrhagic stroke. The objective of this material is to provide local and updated recommendations for the management of patients with spontaneous intracere- bral hemorrhage during hospitalization. For the writing of this manuscript, diferent specialists were convened to form working groups. Ten central topics expressed as epidemiology, initial care, imaging, blood pressure treatment, reversal of antithrombotics, indication for surgery, seizure prophylaxis, prognosis, prevention of complications and resumption of antithrombotics were raised. For each topic, the most frequent questions of daily practice were raised through PICO questions. After a systematic review of the literature, recommendations were generated, evaluated using the GRADE system and agreed between authors and patients.

Rebound activity after fingolimod cessation: A case - control study.

BACKGROUND: There has been an increase in the number of reports of multiple sclerosis (MS) rebound activity (RA), which is usually defined as a severe disease reactivation after natalizumab or fingolimod withdrawal that exceeds pre-treatment baseline inflammatory activity. The frequency and risk factors that could predict RA remain unknown. Fingolimod is currently the most frequently prescribed disease modifying therapy for MS in Argentina, so that there is a need to determine possible predictors of RA. OBJECTIVES: To identify risk factors for developing RA after fingolimod cessation; to describe RA characteristics, management and evolution. METHODS: The study was a multicenter, retrospective, case-control study of patients with MS who had discontinued fingolimod and were followed up to nine months after discontinuation. Demographic, clinical and paraclinical data was extracted, including age, gender, MS phenotype, reason for discontinuation, number of relapses during the year prior to suspension, time treated with fingolimod, EDSS before, during and after rebound, MRI findings. RESULTS: 26 cases of RA were matched 1:1 with patients without RA. The median time elapsed to RA was 50 days. 68% showed worsening of the EDSS in the evaluation at 3 months of RA. When compared with the control group, no difference was found in terms of age, gender, phenotype, EDSS at the moment of suspension, reason for discontinuation, number of relapses in the previous year, and time on therapy. CONCLUSION: In this case-controlled study, no risk factors could be identified to predict RA after fingolimod cessation. Further controlled, prospective, better powered studies are needed to confirm these findings.

Cerebral venous thrombosis in Argentina: clinical presentation, predisposing factors, outcomes and literature review.

BACKGROUND: Cerebral venous thrombosis (CVT) is a rare medical condition that primarily affects young adults. The clinical spectrum is broad and its recognition remains a challenge for clinicians. Limited information is available on CVT in Argentina. Our goal was to report the results of the first National registry on CVT in Argentina and to compare clinical presentation, predisposing factors and outcomes with other international registries. MATERIAL AND METHOD: The Argentinian National Registry on CVT (ANR-CVT) is a multicenter retrospective cohort study comprising patients aged 18 and older with a diagnosis of CVT from January 2015 to January 2019. We evaluated demographics, predisposing factors, clinical presentation, and radiological characteristics (e.g. number of involved sinuses, venous infarction or hemorrhage on CT and MRI scans at admission), therapeutic interventions and functional outcomes at discharge and at 90 days. Our results were compared to a literature review of CVT registries. RESULTS: Overall, one hundred and sixty-two patients met the inclusion criteria. The mean age was 42 (±17) years; 72% were women. Seventy percent of patients were younger than 50 years. The most common presenting symptom was headache (82%). The transverse sinus was the most common site of thrombosis (70%) followed by the sigmoid sinus (46%). The main predisposing factor in women was contraceptive use (44%), 3% of the events occurred during pregnancy and 9% during the puerperium. Participants 50 years and older had a higher frequency on malignancy related (7.5% vs. 30%, p = 0.0001) and infections (2% vs. 11%, p = 0.001). The modified Rankin Scale (mRS) ≤2 at discharge was 81% and the rate of mortality at discharge was 4%. At 90 days, the mRS≤2 was 93%. When the ANR-CVT was compared with larger registries from Europe and Asia, the prevalence of cancer among patients with CVT was two to five-fold higher (15% vs. 7% and 3%, respectively; p = 0.002 and p < 0.001). Anticoagulation rates at discharge were also higher (94%) compared to registries from Asia (ASCVT - 68%) or Turkey (VENOST - 67%). CONCLUSION: Participants in the first ANR-CVT had a low mortality and disability at 90 days. Clinical and radiological characteristics were similar to CVT from other international registries with a higher prevalence of cancer. There was a high variability in treatment adherence to guidelines as reflected by anticoagulation rates (range 54.5%-100%) at discharge.

Delayed Hypoxic Leukoencephalopathy (DHL) is a rare demyelinating disease. This condition occurs days or weeks after a hypoxic-anoxic injury. Symptoms and imaging changes almost fully resolve, with a good prognosis. We report the case of a young woman who developed DHL after a cardiopulmonary arrest.(AU)

Epidemiological aspects of stroke in very old patients.

In developed and developing countries, the population of very old people (more than 80 years) is expected to increase over the coming decades. By 2050, there will be an estimated 56.9 million nonagenarians worldwide, an 800% increase compared with today. In this group, the prevalence and incidence of stroke is very high, with great impact on morbidity and mortality. Only 10% of survivors may expect desirable recovery, and over 50% results with severe disability, the majority of them requiring in-home geriatric care or admittance to nursing homes. In spite of this, clinical trials that investigate acute management and primary and secondary prevention drugs are scarce in this population because most of the main trials excluded patients over 80 years. Results in young patients can not be extrapolated. In the elderly population, decrease in hepatic and renal function, metabolic pathways disturbances, polypharmacy and cognitive decline affects the efficacy, safety and adherence to long-term treatments. In this issue of the journal, we will review the evidence of acute treatment (intravenous thrombolysis) in the reduction of the functional impact of ischemic events in the very old. We will also evaluate the different therapies (antihypertensive and hypolipidemic drugs) in primary and secondary prevention and discuss the management of desired blood pressure levels. We will analyze the safety, efficacy and tolerability of statin therapy in this special group. A deeper understanding of the characteristics of aged patients would facilitate a better management of their cerebrovascular events.
