ABSTRACT

Resumen Introducción: La distinción clínica entre infecciones arbovirales y las provocadas por rickettsias es crucial para iniciar el tratamiento médico apropiado. Objetivo: Comparar las diferencias entre fiebre manchada de las Montañas Rocosas (FMMR) y otras enfermedades transmitidas por vector (dengue y chikungunya) con presentación clínica similar e identificar los datos que pudieran ayudar al diagnóstico rápido de esas enfermedades. Métodos: Se evaluaron datos sociodemográficos, clínicos y de laboratorio de 399 pacientes de cinco hospitales y clínicas en Sonora, México, entre 2004 y 2016, con el diagnóstico confirmado por laboratorio de FMMR, dengue o chikungunya. Resultados: El grupo con FMMR presentó la mayor letalidad (49/63 muertes, 77.8 %), seguido por el de chikungunya (3/161, 1.9 %) y el de dengue (3/161, 1.9 %). Las diferencias clínicas consistieron en la presencia de exantema, edema y prurito; además, se documentaron diferencias en múltiples biomarcadores como plaquetas, hemoglobina, bilirrubina indirecta y niveles de sodio sérico. Conclusión: El exantema en palmas y plantas, edema y ausencia de prurito, aunados a niveles altos de bilirrubina directa y trombocitopenia severa pudieran ser indicadores útiles para diferenciar a pacientes con FMMR en etapas avanzadas de aquellos con dengue y chikungunya.


Abstract Introduction: Clinical distinction between arbovirus infections and those caused by rickettsia is crucial to initiate appropriate medical treatment. Objective: To compare the differences between Rocky Mountain spotted fever (RMSF) and other vector-borne diseases (dengue and chikungunya) with similar clinical presentation, and to identify data that could aid rapid diagnosis of these diseases. Methods: Sociodemographic, clinical and laboratory data of 399 patients from five hospitals and clinics of Sonora, Mexico, with laboratory-confirmed diagnosis of RMSF, dengue, or chikungunya between 2004 and 2016 were evaluated. Results: The RMSF group had the highest lethality (49/63 deaths, 77.8 %), followed by the chikungunya group (3/161, 1.9 %) and the dengue group (3/161, 1.9 %). Clinical differences included the presence of rash, edema, and pruritus; in addition, differences in multiple biomarkers such as platelets, hemoglobin, indirect bilirubin, and serum sodium levels were documented. Conclusion: Rash on the palms and soles, edema and absence of pruritus, together with high levels of direct bilirubin and severe thrombocytopenia could be useful indicators to differentiate patients at RMSF advanced stages from those with dengue and chikungunya.

ABSTRACT

Resumen Introducción: Los virus del dengue y chikungunya son transmitidos por la hembra de los mosquitos Aedes aegypti y Aedes albopictus, ampliamente distribuidos en zonas tropicales y subtropicales, lo que facilita la co-infección. Objetivo: Determinar la magnitud, la distribución geográfica y el cuadro clínico de la co-infección por dengue y chikungunya. Material y Métodos: Revisión narrativa. Búsqueda en las bases de datos PubMed y Lilacs, utilizando los términos MeSH "Chikungunya", "CHIKV", "DENV", "Dengue" y "coinfection. Se incluyeron los artículos de los últimos 20 años. Resultados: Se incluyeron 45 artículos. El mayor reporte de co-infección fue en Asia seguido de África. En las Américas la información es limitada por la reciente circulación del chikungunya. La magnitud de la co-infección varió entre 0 y 31,9%. No se encontraron diferencias en la distribución de la co-infección por sexo y edad. El cuadro clínico de la mono-infección y la co-infección fue similar. Algunos reportes de caso exponen cuadros graves con afección del sistema nervioso central, manifestaciones hemorrágicas y enfermedad de Still. Conclusión: Las manifestaciones clínicas de la co-infección por dengue y chikungunya son similares a la mono-infección, situación que dificulta el diagnóstico y la medición de su magnitud.


Background: Dengue and chikungunya viruses are transmitted by the female Aedes aegypti and Aedes albopictus, which are widely distributed in tropical and subtropical areas, facilitating coinfection. Aim: To determine the magnitude, geographical distribution and clinical picture of dengue and chikungunya coinfection. Material and Methods: Narrative review. A search in the PubMed and Lilacs databases was made, using the MeSH terms "Chikungunya", "CHIKV", "DENV", "Dengue" and "coinfection. The articles of the last 20 years were included. Results: A total of 45 articles were included. The largest coinfection report was in Asia followed by Africa. In the Americas, the information is limited because of the recent circulation of chikungunya. The magnitude of coinfection varies between 0% and 31.9%. No differences were found in the distribution of coinfection by sex and age. The clinical picture of monoinfection and coinfection was similar. Some case reports show severe cases with central nervous system involvement, hemorrhagic manifestations and Still's disease. Conclusion: The clinical manifestations of coinfection by dengue and chikungunya viruses are similar to those due to monoinfection, which difficult the diagnosis and measurement of its magnitude.

ABSTRACT

Dengue remains an unmet public health burden. We determined risk factors for dengue in-hospital mortality in Brazil. Of 326,380 hospitalised dengue cases in 9-45-year-old individuals, there were 971 deaths. Risk of dying was 11-times higher in the presence of underlying common comorbidities (renal, infectious, pulmonary disease and diabetes), similar to the risk of dying from severe dengue and much higher with the combination. Ensuring access to integrated dengue preventative measures in individuals aged ≥ 9 years including those with comorbidities may help achieve the WHO objective of 50% reduction in mortality and 25% reduction in morbidity due to dengue by 2020.

ABSTRACT

Introdução - Considerada um grave problema de saúde pública mundial em regiões de clima tropical e subtropical, a dengue foi a única dentre as doenças tropicais negligenciadas a apresentar tendência de aumento na mortalidade nos últimos anos. Fatores relacionados ao ciclo de vida do principal vetor, fêmeas do mosquito Aedes aegypti, influenciam a distribuição espacial e o caráter sazonal da doença. A incidência de casos de dengue é dependente de uma complexa rede de relações entre vetor, vírus e hospedeiro, assim como a ocorrência de casos graves e de óbito. Desde a introdução do vírus, o estado de São Paulo vem apresentado epidemias envolvendo número cada vez maior de municípios, de incidência de casos e de óbitos por dengue. Objetivo - Avaliar a distribuição espacial, temporal e espaço-temporal dos óbitos por dengue no estado de São Paulo. Métodos - Trata-se de estudo ecológico, com componentes espacial e temporal, a partir da notificação de óbitos por dengue no SINAN, tendo como unidades de análise os municípios e as microrregiões do estado de São Paulo, no período de 1998 a 2017. Os óbitos por dengue no estado de São Paulo foram descritos segundo sexo e idade. As taxas de mortalidade bruta, padronizada por sexo e idade e suavizada pelo método bayesiano empírico local foram estimadas e mapeadas segundo município de residência. Os sorotipos detectados pelo Instituto Adolfo Lutz foram mapeados segundo microrregião. Estimou-se as tendências temporais da mortalidade. Aglomerados de alto risco espacial e espaço-temporal e de variação espacial na tendência temporal foram detectados e mapeados. O risco relativo espacial da mortalidade por dengue ajustado pelo tempo e covariáveis consideradas foi estimado por modelos Bayesianos Gaussianos Latentes com abordagem INLA (2007 - 2016). Foi aprovado pelo Comitê de Ética em Pesquisa da Faculdade de Saúde Pública da Universidade de São Paulo sob parecer de número 1.687.650. Resultados - Foram identificados 1.121 óbitos por dengue com confirmação laboratorial e residentes no estado de São Paulo entre 1998 e 2017. A mediana de idade foi de 57 anos. A média anual da mortalidade bruta por dengue no estado de São Paulo na série histórica foi de 0,14 óbitos por 100.000 habitantes. Houve tendência de elevação da mortalidade para todos os sexos e idades no período, sendo o crescimento mais proeminente nos adultos com >= 50 anos, e de aumento do percentual de municípios com casos e óbitos ao longo dos anos estudados. Houve associação positiva entre as regiões com maior quantidade de sorotipos e taxas de mortalidade mais elevadas. Aglomerados de alto risco foram identificados nas áreas com alta taxa de mortalidade. O grau de urbanização, número de anos com casos e a introdução de novo sorotipo associaram-se a um maior risco relativo para a mortalidade por dengue. Tanto as taxas de mortalidade mais elevadas, quanto os maiores riscos relativos para o óbito foram observados nas regiões norte, noroeste, oeste, sudeste e litoral do estado de São Paulo. Conclusão - a mortalidade por dengue no estado de São Paulo apresentou padrão cíclico e sazonal, com tendência de elevação principalmente nas faixas etárias mais avançadas. Houve identificação de agregados de área de alto risco, com associação do grau de urbanização, do número de anos com casos e da introdução de novo sorotipo a maior risco de mortalidade por dengue


Introduction - Considered a major global public health problem in tropical and subtropical regions, dengue was the only one among neglected tropical diseases to show an increase in mortality in recent years. Factors related to the life cycle of the main vector, females of Aedes aegypti mosquito, influence the spatial distribution and the seasonal nature of the disease. The incidence of dengue cases is dependent on a complex network of relationships between vector, virus and host, as well as the occurrence of severe cases and death. Since the introduction of the virus, the state of São Paulo has been presenting epidemics involving an increasing number of municipalities, incidence of cases and deaths due to dengue. Objective - To evaluate the spatial, temporal and spatial-temporal distribution of dengue deaths in the state of São Paulo. Methods - This is an ecological study, with spatial and temporal components, based on the notification of dengue deaths at SINAN, with the municipalities and microregions of the state of São Paulo as analysis units from 1998 to 2017. Deaths from dengue in the State of São Paulo were described according to sex and age. The crude mortality rates standardized by sex and age and smoothed by the local empirical Bayesian method were estimated and mapped according to the municipality of residence. The serotypes detected by the Adolfo Lutz Institute were mapped according to microregion. The temporal trends of mortality were estimated. High-risk space and space-time clusters and spatial variation in time trend were detected and mapped. The spatial relative risk of dengue mortality adjusted by time and covariables considered was estimated by Latent Gaussian Bayesian models with INLA approach (2007 - 2016). It was approved by the Research Ethics Committee of the School of Public Health of the University of São Paulo under opinion number 1,687,650. Results - A total of 1,121 dengue deaths with laboratory confirmation were identified and residents of the State of São Paulo between 1998 and 2017. The median age was 57 years. The annual average of the gross mortality from dengue in State of São Paulo in the historical series was 0.14 deaths per 100,000 inhabitants. There was a trend of increased mortality for all sexes and ages in the period, with the most prominent growth in adults aged >= 50 years, and an increase in the percentage of municipalities with cases and deaths over the years studied. There was positive association between the regions with the highest number of serotypes and the highest mortality rates. High-risk clusters were identified in areas with high mortality rates. The degree of urbanization, number of years with cases and the introduction of a new serotype were associated with a higher relative risk for dengue mortality. Both the highest mortality rates and the highest relative risks for death were observed in the north, northwest, west, southeast and coastal regions of the State of São Paulo. Conclusion - dengue mortality in the state of São Paulo presented a cyclical and seasonal pattern, with a tendency to increase mainly in the more advanced age groups. There was identification of high risk area clusters, with association of the degree of urbanization, number of years with cases and the introduction of a new serotype at greater risk of dengue mortality

ABSTRACT

El dengue es una enfermedad viral transmitida por mosquitos que puede ser causa de gravedad y muerte. No existe droga antiviral reconocida como eficaz. Sin embargo, las regularidades de esta enfermedad han permitido la identificación de signos de alarma que anuncian extravasación de plasma e inminencia del choque. El inicio precoz del tratamiento de los pacientes mediante la reposición de líquidos cristaloides por vía intravenosa ha demostrado ser una medida efectiva y salvadora. Se necesita capacitación sistemática y acciones de reorganización de la atención médica en función de la epidemia. Se expone la contribución de los profesionales del Instituto de Medicina Tropical Pedro Kourí y otras instituciones cubanas a ese empeño(AU)


Dengue is a viral disease transmitted by mosquitoes which may be severe and cause death. No antiviral drug has been recognized as effective. However, the regularities of this condition have made it possible to identify warning signs announcing plasma leakage and the imminence of shock. Early start of treatment with intravenous crystalloid fluid replacement has proven to be an effective, life-saving measure. Systematic training actions and reorganization of medical care are required during an epidemic. The paper describes the contribution of professionals from Pedro Kouri Tropical Medicine Institute and other Cuban institutions to this effort(AU)

ABSTRACT

Abstract Since the detection of the Chikungunya virus in America in 2013, two million cases of the disease have been notified worldwide. Severe cases and deaths related to Chikungunya have been reported in India and Reunion Island, estimated at 1 death per 1,000 inhabitants. Joint involvement in the acute and chronic phase is the main clinical manifestation associated with Chikungunya. The severity of the infection may be directly attributable to viral action or indirectly, owing to decompensation of preexisting comorbidities. In Brazil, the virus was identified in 2014, and recently, there has been a significant increase in the number of deaths caused by the Chikungunya virus infection, especially in Pernambuco. However, the numbers of fatalities are probably underreported, since for many cases, the diagnosis of Chikungunya infection may not be considered, for deaths by indirect causes. An increase in the mortality rate within months of epidemic occurrence, compared to previous years has also been reported and may be associated with Chikungunya virus infection. An in-depth investigation of reported mortality in Brazil is necessary, to measure the actual impact of the deaths, thereby, allowing the identification of possible causes. This will alert professionals about the risks, and hence, enable creation of protocols that target reducing mortality.

ABSTRACT

Did death occur DUE TO dengue, or in a patient WITH dengue virus infection? It seems a matter of semantics, but in fact, it underscores how challenging it is to distinguish whether the disease contributed to death, or was itself the underlying cause of death. Can a death be attributed to chikungunya virus, when some deaths occur after the acute phase? Did the virus decompensate the underlying diseases, leading to death? Did prolonged hospitalisation lead to infection, resulting in the patient's progression to death? Were there iatrogenic complications during patient care? The dengue question, for which there has not yet been a definitive response, resurfaces prominently under the chikungunya surveillance scenario. We are facing an epidemic of a disease that seems to be more lethal than previously thought. The major challenge ahead is to investigate deaths suspected of occurring due to arbovirus infections and to understand the role of each infection in the unfavourable outcome.

ABSTRACT

Abstract: INTRODUCTION Currently, dengue fever, chikungunya fever, and zika virus represent serious public health issues in Brazil, despite efforts to control the vector, the Aedes aegypti mosquito. METHODS: This was a descriptive and ecological study of dengue deaths occurring from 2002 to 2013 in São Luis, Maranhão, Brazil. Geoprocessing software was used to draw maps, linking the geo-referenced deaths with urban/social data at census tract level. RESULTS: There were 74 deaths, concentrated in areas of social vulnerability. CONCLUSIONS: The use of geo-technology tools pointed to a concentration of dengue deaths in specific intra-urban areas.

ABSTRACT

Os efeitos da infecção por dengue na gestação são desconhecidos em Rio Branco, Acre, Brasil. O objetivo deste trabalho é determinar os riscos de complicações maternas, fetais e infantis decorrentes da infecção por dengue durante a gestação. Estudo de coorte de gestantes expostas e não expostas ao vírus do dengue no período 2007-2012. Foram estimadas incidências e razões de risco de complicações maternas, fetais e infantis. Na coorte exposta houve 3 óbitos fetais e 5 neonatais. Dois óbitos maternos foram identificados na coorte exposta, desfecho ausente no grupo não exposto (p = 0,040). A coorte exposta apresentou uma razão de riscos - RR = 3,4 (IC95%: 1,02-11,23) para óbito neonatal. Em relação ao desfecho óbito neonatal precoce, a razão de riscos observada foi de 6,8 (IC95%: 1,61-28,75). Dez óbitos infantis ocorreram nos filhos de gestantes expostas e 7 nos de não expostas (RR = 6,0; IC95%: 2,24-15,87). As mulheres infectadas com o vírus do dengue na gestação apresentaram uma razão de riscos maior em relação à ocorrência de óbitos maternos, neonatais e infantis.

Diez óbitos infantiles se produjeron en los hijos de gestantes expuestas y 7 en los de no expuestas (RR = 6,0; IC95%: 2,24-15,87). Las mujeres infectadas con el virus del dengue en la gestación presentaron una razón de riesgos mayor, en relación a la ocurrencia de óbitos maternos, neonatales e infantiles.


The effects of dengue infection during pregnancy have not been previously studied in Rio Branco, Acre State, Brazil. The aim of this study was to determine the risks of maternal, fetal, and infant complications resulting from dengue infection during pregnancy. The study compared two cohorts of pregnant women, exposed versus unexposed to dengue virus, from 2007 to 2012. Incidence rates and risk ratios were estimated for maternal, fetal, and infant complications. In the exposed cohort there were 3 fetal deaths and 5 neonatal deaths. Two maternal deaths were identified in the exposed cohort, as opposed to none in the unexposed group (p = 0.040). The exposed cohort showed a risk ratio (RR) of 3.4 (95%CI: 1.02-11.23) for neonatal death. The risk ratio for early neonatal death was 6.8 (95%CI: 1.61-28.75). Ten infant deaths occurred in children of exposed pregnant women and 7 in unexposed (RR = 6.0; 95%CI: 2.24-15.87). Women infected with dengue virus in pregnancy showed increased risk ratio for maternal, neonatal, and infant mortality.

ABSTRACT

Introducción. El dengue en Colombia es un importante problema de salud pública debido a las enormes pérdidas económicas y sociales que ha provocado, especialmente durante los picos epidémicos. Objetivo. Describir el comportamiento de la mortalidad por dengue en Colombia entre 1985 y 2012. Materiales y métodos. Se hizo un estudio descriptivo. La información se obtuvo de las bases de datos de mortalidad y de las proyecciones de población de 1985 a 2012 del Departamento Administrativo Nacional de Estadística (DANE). Se estimaron tasas de mortalidad, razón de tasas y letalidad. Resultados. Se registraron 1.990 muertes por dengue durante el periodo señalado. Las tasas de mortalidad por dengue aumentaron entre 1985 y 1998. Las tasas más altas se presentaron en hombres menores de 5 años y de 65 o más años de edad. Entre 1995 y 2012 los municipios de categorías 1 a 4 también presentaron las tasas más altas. La letalidad durante el periodo varió entre 0,01 y 0,39 %. Conclusión. El dengue es una enfermedad evitable que debería desaparecer de las estadísticas de mortalidad como causa de defunción. La muerte es evitable en la medida en que se implementen y evalúen las actividades propuestas en la Estrategia de Gestión Integrada (EGI)-Dengue. Se recomienda impulsar el desarrollo de una cultura informática que contribuya a la toma de decisiones y a priorizar la utilización de los recursos asignados.


Introduction: Dengue in Colombia is an important public health problem due to the huge economic and social costs it has caused, especially during the disease outbreaks. Objective: To describe the behavior of dengue mortality in Colombia between 1985 and 2012. Materials and methods: We conducted a descriptive study. Information was obtained from mortality and population projection databases provided by the Departamento Administrativo Nacional de Estadística (DANE) for the 1985-2012 period. Mortality rates, rate ratios, and case fatality rates were estimated. Results: A total of 1,990 dengue deaths were registered during this period in Colombia. Dengue mortality rates presented an increasing trend with statistical significance between 1985 and 1998. Higher mortality rates were reported in men both younger than 5 years and older than 65 years. Between 1995 and 2012, category 1 to 4 municipalities reported the highest mortality rates. Case fatality rates varied during the period between 0.01% and 0.39%. Conclusion: Dengue is an avoidable disease that should disappear from mortality statistics as a cause of death. The event is avoidable if the proposed activities from the Estrategia de Gestión Integrada (EGI)-Dengue are implemented and evaluated. We recommend encouraging the development of an informational culture to contribute to decision making and prioritizing resource allocation.

ABSTRACT

AbstractINTRODUCTION:

Studies that generate information that may reduce the dengue death risk are essential. This study analyzed time trends and risk factors for dengue mortality and fatality in Brazil from 2001 to 2011.

METHODS:

Time trends for dengue mortality and fatality rates were analyzed using simple linear regression. Associations between the dengue mortality and the case fatality rates and socioeconomic, demographic, and health care indicators at the municipality level were analyzed using negative binomial regression.

RESULTS:

The dengue hemorrhagic fever case fatality rate increased in Brazil from 2001 to 2011 (β=0.67; p=0.036), in patients aged 0-14 years (β=0.48; p=0.030) and in those aged ≥15 years (β=1.1; p<0.01). Factors associated with the dengue case fatality rate were the average income per capita (MRR=0.99; p=0.038) and the number of basic health units per population (MRR=0.89; p<0.001). Mortality rates increased from 2001 to 2011 (β=0.350; p=0.002).Factors associated with mortality were inequality (RR=1.02; p=0.001) high income per capita (MRR=0.99; p=0.005), and higher proportions of populations living in urban areas (MRR=1.01; p<0.001).

CONCLUSIONS:

The increases in the dengue mortality and case fatality rates and the associated socioeconomic and health care factors, suggest the need for structural and intersectoral investments to improve living conditions and to sustainably reduce these outcomes.

ABSTRACT

Objetivo: Identificar demoras en la atención médica de personas que fallecieron o se recuperaron de dengue grave en cinco ciudades de Colombia. Materiales y métodos. Estudio cualitativo sobre personas que fallecieron por dengue (casos) o que se recuperaron (controles). Se entrevistó a los familiares y se analizaron sus itinerarios de búsqueda de atención en salud. Los datos fueron analizados desde el modelo de las "tres demoras", complementado con diagramas espacio-temporales y entrevistas a profesionales de salud. Resultados: A pesar de desconocer signos y síntomas, se buscó atención rápidamente. Para acceder a la primera consulta el recorrido no representó dificultades. Se presentaron fallas en la calidad del diagnóstico y un mayor número de instituciones consultadas en los casos que en los controles. Se evidenció un proceso de retorno a la demora 1 que puede influir negativamente en futuras decisiones en salud. Conclusiones: Complementar el análisis clásico de demoras con el análisis espacio-temporal de los itinerarios permite visibilizar fallas y aciertos en la calidad de la atención y aportar a la toma de decisiones.


Objetivo: Identificar demoras no atendimento em saúde de pessoas que faleceram ou se recuperaram de dengue grave em cinco cidades da Colômbia. Materiais e métodos: Estudo qualitativo com pessoas que faleceram em decorrência da dengue (casos) ou que se recuperaram (controles). Entrevistaram-se familiares e analisaram-se seus itinerários durante o processo de procura de atendimento nos serviços de saúde. Os dados foram analisados baseados no modelo das "três demoras", complementado com diagramas espaço-temporais e entrevistas com profissionais de saúde. Resultados: Ainda que os signos e sintomas fossem desconhecidos, procurou-se atendimento rapidamente. O percurso para o acesso à primeira consulta não apresentou dificuldades. Apresentaram-se erros na qualidade do diagnóstico e identificou-se maior número de instituições consultadas em casos do que em controles. Evidenciou-se um processo de retorno à demora 1, fato que pode influir negativamente em decisões futuras. Conclusões: Complementar a análise clássica de demoras com a análise espaço-temporal de itinerários permite identificar falhas e acertos na qualidade do atendimento para a tomada de decisões.


Objective: Identify delays in receiving healthcare in cases of patients who either recovered from or died due to severe dengue in five Colombian cities. Method: Qualitative study with deceased persons from dengue (cases) or that recuperated (controls). Family members were interviewed and their itineraries were analyzed. The data was analyzed from the "three delay" model, complemented with spatiotemporal diagrams and interviews to health professionals. Results: Despite not knowing signs and symptoms, attention was rapidly sought. There were no difficulties accessing the route to the first consultation There were flaws in the quality of diagnosis and a higher number of institutions were consulted in cases than in controls. It was evidenced a return to delay 1 that could negatively influence future health decisions. Conclusions: Complementing the delay analysis with spatiotemporal analysis of the itineraries permits the visualization of flaws and successes in the quality of care for decision-making.

ABSTRACT

Introdução: O sistema de vigilância epidemiológica da dengue tem um papel primordial nas atividades de prevenção e controle da doença. Em 2014, o Ministério da Saúde do Brasil atualizou a definição de caso usada pela vigilância para notificação de pacientes suspeitos de dengue. Entretanto, o desempenho da nova definição de caso ainda não foi avaliado, tão pouco foi avaliado a validade do sistema nacional de informação no registro de casos de dengue. Objetivo: Avaliar a validade do registro de casos suspeitos da dengue pelo SINAN e a nova definição de caso suspeito de dengue. Metodologia: Entre 2009 e 2011, pacientes atendidos em um centro de emergência de Salvador por uma doença febril aguda (DFA) de duração ≤7 dias foram entrevistados para coleta de dados sobre a presença das manifestações clínicas usadas na definição de caso suspeito de dengue. A leucometria foi obtida dos prontuários. Amostras de sangue foram coletadas no dia do atendimento e após 14 dias, e testes de referência (ELISA-IgM, ELISA-NS1 e RT-PCR) foram usados para confirmação laboratorial da dengue. A base de dados do SINAN para 2009-2011 com o registro dos casos notificados de dengue no Distrito Sanitário para o nosso período de estudo foi obtida diretamente na coordenação de vigilancia epidemiológica da Secretaria Municipal de Saúde. A sensibilidade (SEN), a especificidade (ESP), os valores preditivos positivo e negativo (VVP e VPN) dos registros de dengue no SINAN bem como dos sintomas utilizados na definiçao de casos foram estimado. O intervalo de confiança de 95% foi utilizado para todas as análises. O projeto foi aprovado pelo CEP-CPqGM- e CONEP. Resultados: No período de 2009-2011, 3.864 pacientes com DFA foram incluídos no estudo, 997 (25,8%) foram laboratorialmente confirmados para dengue e 2.867 (74,2%)...


Introduction: The epidemiological surveillance system dengue has a key role in the prevention and control of disease. In 2014, the Ministry of Health of Brazil updated the case definition used for surveillance for reporting suspected dengue patients. However, the performance of the new case definition has not yet been rated, so little was assessed the validity of the national system of information in the registry of dengue cases. Objective: Evaluate the validity of the registration of suspected cases of dengue by SINAN and the new definition of suspect dengue fever. Methods: Between 2009 and 2011, patients from an emergency center of Salvador by an acute febrile illness (DFA) ≤7 days were interviewed to collect data on the presence of clinical manifestations used in the definition of suspect dengue fever. The white blood cell count and the result of the tourniquet test were obtained from medical records. Blood samples were collected at treatment day and after 14 days, and reference tests (ELISA-IgM ELISA-NS1 and RT-PCR) were used for laboratory confirmation of dengue. The base SINAN data for 2009-2011 with registry of reported cases of dengue in the Sanitary District for our study period was obtained directly by coordinating epidemiological surveillance of the Municipal Health. The sensitivity (SEN), specificity ( ESP), positive and negative predictive values (PPV and NPV) of dengue records in SINAN and symptoms used to define cases were estimated. The 95% confidence interval was used for all analyzes. The project was approved by CEP-CPqGM- and CONEP. Results: In the period 2009-2011, 3,864 patients with DFA were included in the study, 997 (25.8%) were laboratory confirmed dengue and 2,867 (74.2%)...

ABSTRACT

Introducción: el dengue presenta diversas formas clínicas, desde asintomáticas hasta fatales. Existen diversos factores de riesgo asociados a la mortalidad por dengue. Objetivo: determinar los factores de riesgo asociados a la mortalidad por dengue. Metodología: estudio de casos (adultos fallecidos por dengue) y controles (adultos sobrevivientes al dengue), durante la epidemia verano 2012-2013 en Paraguay. Resultados: los factores de riesgo asociados significativamente a la mortalidad por dengue fueron: presencia de comorbilidades, hemorragias, hepatitis, hipoproteinemia e hipoalbuminemia. El choque por dengue fue la causa de óbito más frecuente (49%). Conclusiones: los factores asociados a la mortalidad por dengue son inherentes al paciente (comorbilidades) y a la gravedad de la infección, resultante de las manifestaciones hemorrágicas, afectación sistémica y fuga capilar.


Introduction: Dengue has several clinical forms, from asymptomatic to fatal. There are several risk factors associated with mortality from dengue. Objective: To determine the risk factors associated with mortality from dengue. Methodology: case studies (death of dengue adults) and controls (survivors dengue adults) during summer 2012-2013 epidemic in Paraguay. Results: Risk factors significantly associated with mortality from dengue were: presence of comorbidities, hemorrhage, hepatitis, hypoproteinemia and hypoalbuminemia. Dengue shock syndrome was the most common cause of death (49%). Conclusions: The mortality associated with dengue factors are inherent to the patient (comorbidities) and the severity of infection, resulting in hemorrhagic manifestations, systemic involvement and capillary leak.osus reaction.

ABSTRACT

Objetivo: A dengue tem importância mundial por sua morbidadee abrangência. O presente artigo teve como objetivo descrever as principais características dos óbitos por dengue,ocorridos no Município do Rio de Janeiro (MRJ), durante aepidemia de 2012. Métodos: Foram descritos os 35 casosde óbitos por dengue ocorridos em 2012 neste município. Asvariáveis estudadas foram coletadas a partir das fichas de investigaçãode óbitos por dengue, padronizadas pelo Ministério daSaúde. Resultados: Encontrou-se maior proporção de óbitosentre 50 e 59 e acima de 70 anos, presença de comorbidadesem 77,8%, ligeiro predomínio do sexo masculino e da raça/corpreta. Principais achados hematológicos: leucopenia em 46,8%,leucocitose em 78,1%, hemoconcentração em 39,4% e plaquetopeniaem 87,9%. Na parte bioquímica: aumento de amilaseem 50%, gama GT em 92,8%, transaminase glutâmico oxaloacética(TGO) em 95,2%, transaminase glutâmico pirúvica(TGP) em 80,9%, bilirrubinas em 69,2%, creatina-fosfoquinase(CPK) em 50% e lactato desidrogenase (LDH) em 100%. Derramecavitário foi descrito em 64,3% e espessamento de parededa vesícula biliar em 37,5%. Manifestações atípicas evidenciadas:neurológicas 8,6%, insuficiência hepática 11,4%, insuficiênciarenal 25,7% e sangramento 22,8%. Conclusão: Oacompanhamento de exames laboratoriais e de imagem auxilia omanejo clínico e a predição da gravidade da dengue. Este acompanhamento,juntamente com a estabilização das morbidadespreexistentes, pode reduzir sua letalidade.(AU)


Objectives: Dengue has global significance for its morbidityand scope. This article aims to describe the main features of deathsdue to dengue, during the dengue epidemic in Rio de Janeiro(MRJ) in 2012. Methods: The 35 cases of obit by dengueoccurred in 2012 in this municipality were described. The studiedvariables were collected from the records of investigation of obitby dengue, standardized by the Ministry of Health. Results:Review of 35 deaths due to dengue that occurred in the city ofRio de Janeiro in 2012 showed a higher proportion between agesof 50 and 59 and also greater than 70 years old, the presence ofcomorbidities in 77.8% and a slight prevalence in male gender andin race/color black. Major hematologic findings were leukopenia(46.8%), leukocytosis (78.1%), hemoconcentration (39.4%)and thrombocytopenia (87.9%). Other lab abnormalities wereamylase (50%), gamma GT (92.8%), aspartate aminotransferase(AST) (95.2%), serum glutamate pyruvate transaminase (SGPT)alanine transferase (ALT) in 80.9%, bilirubin in 69.2%, creatinephosphokinase in 50% (5/10) and lactate dehydrogenase in100%. Cavity effusions were described in 60% and thickenedgallbladder in 37.5%. Atypical symptoms that were evident:neurological 8.6%, liver failure, 11.4%, kidney failure, 25.7%and bleeding 22.8%. Conclusion: Monitoring the levelsof hematocrit, platelets, aminotransferases and imaging tests helpthe clinical management and prediction of severity of dengueand, along with the stabilization of preexisting comorbidities,may reduce its lethality.(AU)
