Detection of encephalitis-causing viruses reveals predominance of chikungunya virus in the state of Bahia, Brazil.

OBJECTIVES: Encephalitis is a severe neurological syndrome for which herpesvirus and enteroviruses are the most common etiological agents. Arboviruses, a wildly diverse group of pathogens, are also critical epidemiological agents associated with encephalitis. In Brazil, little is known about the causative agents of encephalitis. METHODS: We conducted a hospital surveillance for encephalitis between 2020 and 2022. Molecular (RT-PCR and qPCR) and serological (virus-specific IgM and viral antigens) techniques were performed in cerebrospinal fluid and serum samples obtained from study participants. RESULTS: In the 43 participants evaluated, the etiologic agent or the presence of IgM was detected in 16 (37.2%). Nine (20.9%) cases were positive for chikungunya virus (CHIKV), three (7.0%) for dengue virus, two (4.7%) for human adenovirus, one (2.3%) for varicella-zoster virus, and one (2.3%) for enterovirus. Whole-genome sequencing revealed that the CHIKV identified belongs to the East/Central/South African lineage. CONCLUSION: Herein, CHIKV is a common pathogen identified in encephalitis cases. Our results reinforce previous evidence that chikungunya represents a significant cause of encephalitis during CHIKV outbreaks and epidemics and add to existing information on the epidemiology of encephalitis in Brazil.

Morbimortality and determinants of reperfusion in ischemic stroke

SUMMARY BACKGROUND: Cerebrovascular accident (or stroke) and ischemic heart disease are the the major causes of death in the world. It is estimated that about 85% of strokes are ischemic in origin. Reperfusion therapy in the acute phase of ischemic stroke with a recombinant human tissue plasminogen activator is effective, but some factors influence the success of this treatment. OBJECTIVE: The aim of this study was to evaluate clinical aspects and possible determinants for reperfusion after venous thrombolysis. METHODS: This is a retrospective, cross-sectional, observational study based on a review of hospital records of inpatients diagnosed with ischemic stroke treated with intravenous thrombolysis, the main outcome being reperfusion or not. RESULTS: Data from this study revealed a predominance of females in the group of reperfused patients and males in the non-reperfused group, both maintaining moderate severity on the National Institutes of Health Stroke Scale and admission without statistical significance (p>0.18). In addition, the mean admission severity score was 13.2 for the group of reperfused patients and 14.2 for those not reperfused, and the mean ejection fraction of both groups was within normal functionality, with a mean of 0.50 for reperfused patients and 0.62 for non-reperfused patients. CONCLUSION: We found an association between successful venous chemical thrombolysis reperfusion and lower mortality in patients with acute stroke.

Factors associated with decision time to seek care in the face of ischemic stroke.

OBJECTIVE: To verify the association between sociodemographic, clinical, environmental, cognitive, and emotional factors and the decision time of people with ischemic stroke to seek a health service after the onset of symptoms or wake up stroke. METHOD: Cross-sectional study carried out from March to October 2019, with 304 patients, in a public hospital, a reference in neurology. Data obtained through interview and from medical records. Decision time was analyzed as a geometric mean. In the bivariate and multivariate analyses, linear regression was used and the Akaike Information Criterion was used to select the best model. Statistical significance of 5% was adopted. RESULTS: The geometric mean of decision time was 0.30h (95% CI 0.23-0.39). The final model explained this time in 41%, showing an increase of 0.5 min for people with arterial hypertension; 10.8 min for those who waited for symptoms to improve; 1.4 min for those who were alone at the onset of symptoms; 3.9 min for those at home; 3.2 min for the ones at work; and 2.1 for those on the street/public space. CONCLUSION: The mean decision time for seeking a health service was high and influenced by clinical, environmental, cognitive, and emotional variables. The results guide nurses regarding health education.

"Long-term oncologic outcomes and risk factors for distant recurrence after pathologic complete response following neoadjuvant treatment for locally advanced rectal cancer. A nationwide, multicentre study".

BACKGROUND: Pathologic complete response (pCR) after multimodal treatment for locally advanced rectal cancer (LARC) is used as surrogate marker of success as it is assumed to correlate with improved oncologic outcome. However, long-term oncologic data are scarce. METHODS: This retrospective, multicentre study updated the oncologic follow-up of prospectively collected data from the Spanish Rectal Cancer Project database. pCR was described as no evidence of tumour cells in the specimen. Endpoints were distant metastases-free survival (DMFS) and overall survival (OS). Multivariate regression analyses were run to identify factors associated with survival. RESULTS: Overall, 32 different hospitals were involved, providing data on 815 patients with pCR. At a median follow-up of 73.4 (IQR 57.7-99.5) months, distant metastases occurred in 6.4% of patients. Abdominoperineal excision (APE) (HR 2.2, 95%CI 1.2-4.1, p = 0.008) and elevated CEA levels (HR = 1.9, 95% CI 1.0-3.7, p = 0.049) were independent risk factors for distant recurrence. Age (years) (HR 1.1; 95%-CI 1.05-41.09; p < 0.001) and ASA III-IV (HR = 2.0; 95%-CI 1.4-2.9; p < 0.001), were the only factors associated with OS. The estimated 12, 36 and 60-months DMFS rates were 96.9%, 91.3%, and 86.8%. The estimated 12, 36 and 60-months OS rates were 99.1%, 94.9% and 89.3%. CONCLUSIONS: The incidence of metachronous distant metastases is low after pCR, with high rates of both DMFS and OS. The oncologic prognosis in LARC patients that achieve pCR after neoadjuvant chemo-radiotherapy is excellent in the long term.

Arrival time at a referral hospital and functional disability of people with stroke: a cohort study.

BACKGROUND: Stroke is a major cause of death and functional disability worldwide. Knowledge of the associated factors is essential for defining education, management, and healthcare strategies. OBJECTIVE: To analyze the association between arrival time at a neurology referral hospital (ATRH) and functional disability in patients with ischemic stroke 90 days after the event. DESIGN AND SETTING: Prospective cohort study conducted at a public institution of higher education in Brazil. METHODS: This study included 241 people aged ≥ 18 years who presented ischemic stroke. The exclusion criteria were death, inability to communicate without companions who could answer the research questions, and > 10 days since ictus. Disability was assessed using the Rankin score (mR). Variables for which associations showed a P value ≤ 0.20 in bivariate analysis were tested as modifiers between ATRH and disability. Significant interaction terms were used for multivariate analysis. Multivariate logistic regression analysis was performed with all variables, arriving at the complete model and adjusted beta measures. The confounding variables were included in the robust logistic regression model, and Akaike's Information Criterion was adopted to choose the final model. The Poisson model assumes a statistical significance of 5% and risk correction. RESULTS: Most participants (56.0%) arrived at the hospital within 4.5 hours of symptom onset, and 51.7% presented with mRs of 3 to 5 after 90 days of ictus. In the multivariate model, ATRH ≥ 4.5 hours and females were associated with more significant disability. CONCLUSIONS: Arrival at the referral hospital 4.5 hours after the onset of symptoms or wake-up stroke was an independent predictor of a high degree of functional disability.

Ischemic stroke mortality and time for hospital arrival: analysis of the first 90 days.

OBJECTIVE: To analyze the association between time of arrival at a reference hospital and mortality of people with ischemic stroke. METHOD: Descriptive and inferential statistics were used. Modifying and confounding variables between time of arrival and mortality were observed in the multivariate analysis. The Akaike Information Criterion was used to choose the model. Statistical significance of 5% and risk correction using the Poisson Model were adopted. RESULTS: Most participants arrived within 4.5 hours of symptom onset or wake up stroke to the referral hospital and 19.4% died. The score of the National Institute of Health Stroke Scale was a modifier. In the multivariate model stratified by scale score ≥14, arrival time >4.5h was associated with lower mortality; and age ≥60 years and having Atrial Fibrillation, to higher mortality. In the model stratified by score ≤13, previous Rankin ≥3, and presence of atrial fibrillation were predictors of mortality. CONCLUSION: The relationship between time of arrival and mortality up to 90 days was modified by the National Institute of Health Stroke Scale. Prior Rankin ≥3, atrial fibrillation, time to arrival ≤4.5h, and age ≥60 years contributed to higher mortality.

Development of a new non invasive prognostic stroke scale (NIPSS) including triage elements for sleep apnea and peripheral artery disease.

BACKGROUND: Although sleep apnea and peripheral artery disease are prognostic factors for stroke, their added benefit in the acute stage to further prognosticate strokes has not been evaluated. OBJECTIVES: We tested the accuracy in the acute stroke stage of a novel score called the Non-Invasive Prognostic Stroke Scale (NIPSS). PATIENTS AND METHODS: Prospective cohort with imaging-confirmed ischemic stroke. Clinical data, sleep apnea risk score (STOPBANG) and blood pressure measures were collected at baseline. Primary outcome was the 90-day modified Rankin Scale (mRS), with poor outcome defined as mRS 3-6. Area under the ROC curve (AUC) was calculated for NIPSS and compared to six other stroke prognostic scores in our cohort: SPAN-100 index, S-SMART, SOAR, ASTRAL, THRIVE, and Dutch Stroke scores. RESULTS: We enrolled 386 participants. After 90 days, there were 56% with poor outcome, more frequently older, female predominant and with higher admission National Institute of Health Stroke Scale (NIHSS). Four variables remained significantly associated with primary endpoint in the multivariable model: age (OR 1.87), NIHSS (OR 7.08), STOPBANG category (OR 1.61), and ankle-braquial index (OR 2.11). NIPSS AUC was 0.86 (0.82-0.89); 0.83 (0.79-0.87) with bootstrapping. When compared to the other scores, NIPSS, ASTRAL, S-SMART and DUTCH scores had good abilities in predicting poor outcome, with AUC of 0.86, 0.86, 0.83 and 0.82, respectively. THRIVE, SOAR and SPAN-100 scores were fairly predictive. DISCUSSION AND CONCLUSIONS: Non-invasive and easily acquired emergency room data can predict clinical outcome after stroke. NIPSS performed equal to or better than other prognostic stroke scales.

Mielopatias inflamatórias / Inflammatory myelopathies / Mielopatías inflamatorias

Mielopatia inflamatória ou mielite transversa é uma síndrome neurológica potencialmente incapacitante com uma variedade de etiologias. Episódios únicos ou recorrentes podem resultar em dependência de cadeira de rodas. O quadro clínico de fraqueza, alteração de sensibilidade e disfunção autonômica de início agudo ou subagudo é marca dessa síndrome. Esse cenário é comum às diferentes etiologias, que podem ser de natureza desmielinizante, por doença autoimune sistêmica, paraneoplásica ou infecciosa. A ressonância magnética de coluna é o exame de neuroimagem de escolha. Exames complementares como avaliação do líquido cefalorraquidiano, testes sorológicos e pesquisa de anticorpos dão suporte à investigação. A depender da etiologia, há tratamentos específicos a fim de reduzir incapacidade e chance de novos surtos, além de diferentes prognósticos. Este trabalho objetiva uma revisão de literatura sobre mielopatias inflamatórias e suas principais etiologias, a partir de dados obtidos na plataforma eletrônica PubMed. Para a discussão, foram revisadas as etiologias desmielinizantes (encefalomielite disseminada aguda, esclerose múltipla, doença do espectro, neuromielite óptica e neurite óptica, encefalite e mielite associadas ao MOG-IgG); doenças autoimunes (lúpus eritematoso sistêmico e síndrome de Sjögren); síndromes paraneoplásicas e mielopatias infecciosas (neuroesquistossomose, mielite por HIV e por HTLV-1 e neurossífilis). Concluiu-se com este estudo que a mielopatia inflamatória é uma condição de gravidade variável que produz potencial incapacidade, causada por diferentes etiologias, porém com quadro clínico comum entre elas. Por isso, é importante conhecer cada uma dessas causas, a fim de promover o melhor e mais precoce tratamento e reduzir sequelas.

Inflammatory myelopathy or transverse myelitis is a potentially disabling neurological syndrome with various etiologies. Single or recurrent episodes can result in wheelchair dependence. A clinical picture of weakness, altered sensitivity, and autonomic dysfunction with acute or subacute onset is characteristic of this syndrome. This scenario is common to different etiologies, which can be of a demyelinating nature, due to systemic, paraneoplastic, or infectious autoimmune disease. Spine MRI is the neuroimaging test of choice. Complementary tests such as cerebrospinal fluid evaluation, serological tests and antibody research support the investigation. Depending on the etiology, there are specific treatments to reduce disability and the chance of new episodes, and different prognoses. This study is a literature review on inflammatory myelopathies and their main etiologies, based on data obtained from the PubMed database. Demyelinating etiologies (acute disseminated encephalomyelitis, multiple sclerosis, neuromyelitis optic spectrum disease and optic neuritis, MOG-IgG-associated encephalitis and myelitis), autoimmune diseases (systemic lupus erythematosus and Sjögren's syndrome), paraneoplastic syndromes and infectious myelopathies (neuroschistosomiasis, HIV and HTLV-1 myelitis, and neurosyphilis) were reviewed for discussion. In conclusion, inflammatory myelopathy is a condition of variable severity that produces potential disability, caused by different etiologies, but with a common clinical picture between them. Thus, knowledge on each of these causes is important to promote the best and earliest treatment and reduce sequelae.

La mielopatía inflamatoria o mielitis transversa es un síndrome neurológico potencialmente incapacitante con una variedad de etiologías. Los episodios únicos o recurrentes pueden tener como consecuencia dependencia de silla de ruedas. El cuadro clínico de debilidad, sensibilidad alterada y disfunción autonómica de inicio agudo o subagudo es distintivo de este síndrome. Esto es común a diferentes etiologías, que pueden ser de naturaleza desmielinizante, debido a enfermedades autoinmunes sistémicas, paraneoplásicas o infecciosas. La resonancia magnética de columna es la prueba de neuroimagen de elección. Las pruebas complementarias, como la evaluación del líquido cefalorraquídeo, las pruebas serológicas y la investigación de anticuerpos respaldan la investigación. Dependiendo de la etiología, existen tratamientos específicos para reducir la discapacidad y la posibilidad de nuevos brotes, además de diferentes pronósticos. Este trabajo tiene como objetivo revisar la literatura sobre mielopatías inflamatorias y sus principales etiologías desde los datos obtenidos de la base de datos electrónica PubMed. Se revisaron las etiologías desmielinizantes (encefalomielitis aguda diseminada, esclerosis múltiple, enfermedad del espectro, neuromielitis óptico y neuritis óptica, encefalitis y mielitis asociadas a MOG-IgG), las enfermedades autoinmunes (lupus eritematoso sistémico y síndrome de Sjögren), los síndromes paraneoplásicos y mielopatías infecciosas (neurosquistosomiasis, mielitis por VIH y HTLV-1 y neurosífilis). Se concluyó que la mielopatía inflamatoria es una condición de severidad variable, que produce potencial discapacidad causada por diferentes etiologías, pero tiene un cuadro clínico común entre ellas. Por ello, es importante conocer cada una de las causas para promover el mejor y más precoz tratamiento, además de reducir las secuelas.

Hospital service for ischemic stroke patients in Brazilian countryside: are we still in the '80s?

BACKGROUND: Stroke is one of the most common causes of death and incapacity in the world. The benefits of reperfusion therapies and hospitalization in neurologic intensive care units (ICUs) are undeniable. However, these treatments are not widely available in a continental-sized country like Brazil. OBJECTIVE: To describe the treatment for ischemic stroke and the functional outcome 90 days after the hospitalization of patients in the Brazilian countryside. METHODS: Observational, prospective case series study design. The data collected refer to randomly selected patients hospitalized in 3 hospitals in the south region of the state of Bahia between December 2018 and December 2019. RESULTS: The population consisted of 61 consecutive patients. They were elderly (median age: 62 years old); with a predominance of hypertension (82%); and were light to moderate stroke cases (National Institute of Health Stroke Scale [NIHSS] median: 7). A total of 37.7% of the cases arrived at the hospital in a < 4.5-hour window but received no reperfusion therapy. Of these, 94.3% were discharged from the hospital with a prescription for antiplatelets or anticoagulant. A total of 64.1% of the patients received a statin prescription. At the end of the follow-up period, the general mortality was 21%. Almost half of the population (47.9%) evolved to an unfavored outcome (modified Rankin scale [mRs]: 3 to 6). CONCLUSION: Our population presented sociodemographic and comorbidities characteristics similar to those of other national samples. No reperfusion therapy was used and the treatment was basically secondary and prophylaxis-oriented, and almost half of the population evolved with incapacities and a high mortality rate, despite the initial low clinical gravity.

ANTECEDENTES: Acidente vascular cerebral (AVC) é uma das principais causas de morte e incapacidade no mundo. Os benefícios das terapias de reperfusão e hospitalização em unidade intensiva neurológica são inegáveis. Porém, estes tratamentos não estão largamente disponíveis em um país de dimensões continentais como o Brasil. OBJETIVOS: Descrever o tratamento do AVC isquêmico agudo e a funcionalidade, 90 dias após o evento, de pacientes hospitalizados no interior do Brasil. MéTODOS: Estudo observacional, prospectivo, tipo série de casos. Os dados foram coletados de pacientes consecutivos, aleatoriamente selecionados, internados em 3 hospitais da região Sul da Bahia entre dezembro de 2018 e dezembro de 2019. RESULTADOS: A população amostral consistiu de 61 pacientes. Houve predomínio de idosos (mediana de idade: 62 anos), hipertensos (82%), com AVC leve a moderado (mediana do National Institute ok Health Stroke Scale [NIHSS, na sigla em inglês]: 7), dos quais 37,7% chegaram ao hospital com < 4,5 horas de sintomas, mas não receberam terapias de reperfusão. Um total de 94,3% dos pacientes recebeu alta com prescrição de antiagregante plaquetário ou anticoagulante e 64,1% receberam prescrição de estatina. Ao final do período de seguimento, a mortalidade geral foi de 21% e quase metade da população amostral (47,9%) evoluiu com desfecho desfavorável (escala de Rankin modificada: 3 a 6). CONCLUSãO: A população amostral apresentou características sociodemográficas e comorbidades semelhantes às de outros recortes nacionais. Terapias de reperfusão não foram realizadas e o tratamento foi basicamente orientado para profilaxia secundária. Quase metade da população evoluiu com incapacidade ou morte, apesar da baixa gravidade clínica à admissão.

Predictors of functional communication in people with aphasia after stroke.

BACKGROUND: Aphasia, the most common language disorder secondary to stroke, has been associated with increased mortality, longer hospitalization and rehabilitation times, worse performance in daily activities, increased financial burden, and short- and long-term complications. Aphasia can negatively impact functional communication skills, including social networks, social activities, relationships with other people and social support. OBJECTIVE: To evaluate patients with poststroke aphasia in their respective residences to investigate potential predictors of functional communication. METHODS: The prospective cohort included patients with poststroke aphasia aged 18 years or older who resided in the city of Salvador, Northeastern Brazil. Following discharge from the Stroke Unit (SU), the individuals themselves, or their guardians, were contacted by telephone to schedule a home visit no less than three months after discharge. At baseline, sociodemographic and clinical data were collected, in addition to the scores on the National Institutes of Health Stroke Scale (NIHSS) and modified Barthel Index (mBI). The American Speech-Language-Hearing Association Functional Assessment of Communication Skills for Adults (ASHA FACS) was applied at the patients' homes. Multivariate linear regression was employed using the total score on the ASHA FACS as the outcome of interest. RESULTS: A multivariate analysis of the associated factors identified using the linear regression revealed that only functional capacity (as assessed by the mBI) upon discharge from the SU remained as an independent predictor of functional communication performance (ß = 0.042; 95% confidence interval [95%CI] = 0.013-0.071; p = 0.002). CONCLUSION: The functional capacity to perform daily activities, evaluated upon discharge from a stroke unit, was identified as a potential predictor of functional communication performance, regardless of the time elapsed after the stroke.

ANTECEDENTES: A afasia, distúrbio de linguagem mais comum secundário ao acidente vascular cerebral (AVC), está associada ao aumento da mortalidade, a um maior tempo de internação e reabilitação, ao pior desempenho nas atividades diárias, ao aumento da carga financeira, e às complicações de curto e longo prazos. Pode impactar negativamente as habilidades de comunicação funcional, incluindo atividades sociais, relacionamento com outras pessoas, e o apoio social. OBJETIVO: Avaliar pacientes com afasia pós-AVC em suas respectivas residências para investigar potenciais preditores de comunicação funcional. MéTODOS: A coorte prospectiva incluiu pacientes com afasia pós-AVC com 18 anos de idade ou mais, residentes em Salvador, Brasil. Após a alta da Unidade de AVC (UAVC), os próprios indivíduos, ou seus responsáveis, foram contatados por telefone para agendamento de visita domiciliar no mínimo três meses após a alta. Inicialmente, foram coletados dados sociodemográficos e clínicos, além das pontuações na National Institutes of Health Stroke Scale (NIHSS) e no Índice de Barthel modificado (IBM). O American Speech-Language-Hearing Association Functional Assessment of Communication Skills for Adults (ASHA FACS) foi aplicado no domicílio dos pacientes. A regressão linear multivariada foi empregada usando a pontuação total no ASHA FACS como o desfecho de interesse. RESULTADOS: A análise multivariada por meio de regressão linear revelou que apenas a capacidade funcional avaliada na alta da UAVC permaneceu como preditor independente do desempenho da comunicação funcional (ß = 0,042; intervalo de confiança de 95% [IC95%] = 0,013­0,071; p = 0,002). CONCLUSãO: A capacidade funcional para realizar as atividades diárias, avaliada na alta hospitalar, foi identificada como potencial preditor do desempenho da comunicação funcional, independente do tempo desde o AVC.

Hospital service for ischemic stroke patients in Brazilian countryside: are we still in the '80s? / Tratamento hospitalar a vítimas de acidente vascular cerebral isquêmico no interior do Brasil: ainda estamos na década de 80?

Abstract Background Stroke is one of the most common causes of death and incapacity in the world. The benefits of reperfusion therapies and hospitalization in neurologic intensive care units (ICUs) are undeniable. However, these treatments are not widely available in a continental-sized country like Brazil. Objective To describe the treatment for ischemic stroke and the functional outcome 90 days after the hospitalization of patients in the Brazilian countryside. Methods Observational, prospective case series study design. The data collected refer to randomly selected patients hospitalized in 3 hospitals in the south region of the state of Bahia between December 2018 and December 2019. Results The population consisted of 61 consecutive patients. They were elderly (median age: 62 years old); with a predominance of hypertension (82%); and were light to moderate stroke cases (National Institute of Health Stroke Scale [NIHSS] median: 7). A total of 37.7% of the cases arrived at the hospital in a < 4.5-hour window but received no reperfusion therapy. Of these, 94.3% were discharged from the hospital with a prescription for antiplatelets or anticoagulant. A total of 64.1% of the patients received a statin prescription. At the end of the follow-up period, the general mortality was 21%. Almost half of the population (47.9%) evolved to an unfavored outcome (modified Rankin scale [mRs]: 3 to 6). Conclusion Our population presented sociodemographic and comorbidities characteristics similar to those of other national samples. No reperfusion therapy was used and the treatment was basically secondary and prophylaxis-oriented, and almost half of the population evolved with incapacities and a high mortality rate, despite the initial low clinical gravity.

Guillain-Barré Syndrome and Miller Fisher Syndrome in Association With an Arboviral Outbreak: A Brazilian Case Series.

Introduction: Guillain-Barré syndrome (GBS) in association with arboviruses, such as Zika, chikungunya, and dengue, has been previously documented; however, Miller-Fisher Syndrome (MFS) and other GBS subtypes are rarely reported. Methods: We identified a series of GBS and MFS cases that were followed during the Zika virus outbreak in Salvador, Brazil (2015-2016). Blood and CSF samples were collected for virus diagnosis. In addition, serological studies to verify previous arboviral infection and electromyography (EMG) were performed. Results: Of the 14 patients enrolled, 10 were diagnosed with GBS, including three GBS subtypes (two cases of bifacial weakness with paresthesia and one case of paraparetic GBS), and four as MFS. IgM antibodies against one or more of three arboviruses were present in 11 (78.6%) patients: anti-zika IgM positivity in eight (57%), anti-Chikungunya IgM in three (21%), and anti-Dengue in one (7%) individual. A single case was positive for both anti-Dengue IgM and anti-Chikungunya IgM, suggesting co-infection. EMG revealed an AIDP pattern in all nine patients analyzed. Conclusion: The current case series contributes to our knowledge on the clinical presentation of arbovirus-associated GBS and its subtypes, including MFS, and serves as an alert to clinicians and other healthcare professionals in regions affected by arbovirus outbreaks. We highlight the importance of recognizing arboviruses in diagnosing GBS and its subtypes.

Chagas disease is an independent predictor of stroke and death in a cohort of heart failure patients.

BACKGROUND AND AIMS: Chagas disease is a common cause of heart failure (HF) and death in developing countries. Although stroke is known to occur in these patients, an accurate estimate of stroke incidence is lacking. We aimed to determine the incidence of stroke and death in patients with HF, comparing Chagas and non-Chagas etiologies. METHODS: Cohort of stroke-free patients with HF (Framingham criteria) followed in a university-based outpatient clinic in Brazil. Baseline characteristics included sociodemographic, risk factor assessment, echocardiographic and electrocardiographic findings. Chagas disease was defined by appropriate serologic tests. Cause-specific Cox regression was used to search for predictors of stroke or death as separate outcomes. RESULTS: We studied 565 patients with HF between January 2003 and December 2018, mean age 54.3 ± 12.9 years, 305 (54.0%) females, 271/535 (50.7%) with Chagas disease. Chagas patients were older (55.5 vs. 53.1 years), more frequently women (60.5% vs. 47.3%), less frequently harbored coronary artery disease (14.5% vs. 34.1%) when compared to non-Chagas patients. Echocardiography showed more severe disease among non-Chagas patients [median left ventricle ejection fraction (LVEF) 37.3% vs. 47.0%]. Over a mean 42.9 (±34.4) months, we followed 404 (71.5%) patients, completing 1442 patient-years of follow-up. Stroke incidence was higher in Chagas when compared to non-Chagas patients (20.2 vs. 13.9 events per 1000 patient-years), while death rate was similar (41.6 vs. 43.1 deaths per 1000 patient-years). In the multivariable analysis for stroke outcome adjusted for LVEF and arrhythmias, cause-specific hazard ratio (CSHR) for Chagas was 2.54 (95% confidence interval 1.01-6.42, p = 0.048). Chagas disease was also associated with increased risk of death (CSHR 1.83; 95% confidence interval 1.04-3.24, p = 0.037). CONCLUSION: Chagas disease is associated with increased risk of stroke and death when compared to other etiologies of HF, independently of HF severity or cardiac arrhythmias, suggesting other factors contribute to increased stroke risk and mortality in Chagas disease. Early prevention and treatment of Chagas disease is imperative to reduce a later risk of stroke in endemic areas.
