RESUMO

OBJECTIVE: to describe drug-resistant tuberculosis (DR-TB) notifications in Brazil. METHODS: this is a descriptive study of clinical and epidemiological characteristics of DR-TB notifications in 2014 on SITETB and TBWeb, these being information systems on which cases involving special treatment regimens are registered. RESULTS: there were 1,574 cases, 94.8% of which had the pulmonary form, 27.6% involved primary resistance, and 50.9% were multidrug-resistant; 70.6% of cases were male, 87.0% were between 20 and 59 years old, 60.9% were of Afro-Brazilian, and 68.0% had less than 8 years of schooling; as for comorbidities, 13.1% of patients had AIDS, 11.3% had diabetes, 25.8% made harmful use of alcohol, 21.0% were illegal drugs users, and 22.2% were tobacco users. CONCLUSION: the majority of DR-TB notifications were related to men, young people, Afro-Brazilian and people with low levels of education; there was a high percentage of primary resistance, as well as multidrug-resistance and comorbidities, with emphasis on substance use.

RESUMO

Tuberculosis is closely related to living conditions. This study classifies Brazilian municipalities according to the occurrence of tuberculosis (TB) and drug-resistant TB (DR-TB) cases and describes them with regard to the population's health conditions, tuberculosis control indicators, demographic and socioeconomic profile. In 2014, 327 municipalities reported DR-TB cases. Integrated regions of development or metropolitan regions accounted for 80.1% of national DR-TB cases. Municipalities with DR-TB cases had worse TB outcome indicators, but higher culture test percentages, and more inhabitants and better socioeconomic indicators. The 3,644 municipalities with TB cases, but without DR-TB cases, had the worst socioeconomic indicators among the three groups. The 1,594 municipalities without TB cases had the lowest rates of unemployment and AIDS detection and greater coverage of primary healthcare. The different profiles found in the study can sustain improved national interventions for TB and drug-resistant TB control in Brazil.

A tuberculose tem estreita relação com as condições de vida das pessoas. O presente estudo classifica os municípios brasileiros de acordo com a presença ou ausência de casos de tuberculose (TB) e sua forma drogarresistente (TB-DR), e os descreve quanto às condições de saúde da população, os indicadores de controle da tuberculose, perfil demográfico e socioeconômico. Em 2014, 327 municípios registraram casos de TB-DR. Regiões integradas de desenvolvimento ou regiões metropolitanas concentraram 80,1% dos casos de TB-DR do País. Os municípios com casos de TB-DR tiveram piores indicadores de desfecho da TB, mas maiores percentuais de realização de exame de cultura, além de mais habitantes e melhores indicadores socioeconômicos. Os 3.644 municípios com casos de TB, mas sem casos de TB-DR, tiveram os piores indicadores socioeconômicos entre os três grupos. Os 1.594 municípios sem casos de TB tiveram as menores taxas de desemprego e de detecção de AIDS, e maior cobertura de atenção básica. Os diferentes perfis encontrados no estudo podem dar suporte à lapidação de estratégias nacionais de controle da doença e sua forma drogarresistente no País.

RESUMO

The anti-vaccination movement has gained worldwide strength despite the undeniable advances in vaccines in drastically reducing the incidence of contagious diseases. The causes for this breakthrough are still issues of discussion and research, but ignorance, ease of dissemination of false information, and the rise of populist policies have been implicated. The major challenge for the future will be the dichotomy between the interest of public health and individual freedoms. (AU).

El movimiento contra la vacunación ha ganado fuerza en todo el mundo a pesar de los innegables avances en las vacunas para reducir drásticamente la incidencia de enfermedades contagiosas. Las causas de este avance aún son temas de discusión e investigación, pero la ignorancia, la facilidad de difusión de información falsa y el auge de las políticas populistas han sido implicados. El principal desafío para el futuro será la dicotomía entre el interés de la salud pública y las libertades individuales. (AU).

RESUMO

RESUMO: Objetivo: Estimar o volume de vírus circulante de HIV na população brasileira e avaliar o potencial impacto da terapia antirretroviral (HAART) na redução de novas infecções, com o propósito de construir evidências e informações para subsidiar a implementação de políticas de saúde. Métodos : Ferramentas de análise espacial foram utilizadas para descrever os padrões existentes na densidade da carga viral utilizando o método Kernel quártico. As informações da carga viral e tratamento são oriundas da base conjunta do Sistema de Controle de Exames Laboratoriais (Siscel), com informações do histórico da carga viral do indivíduo e do Sistema de Controle Logístico de Medicamentos (Siclom), que controla a dispensa dos medicamentos para a terapia antirretroviral. Resultados: Observou-se que a carga viral comunitária (CVC) apresentou redução progressiva no período de 2007 a 2011, acompanhada de uma redução da carga viral média (CVCM) superior a 32% (22.900 cópias/mL em 2007 versus 15.418 cópias/mL em 2011). Nesse período, houve redução da CVCM em todas as grandes regiões do Brasil, embora o Norte e Nordeste tenham apresentado, respectivamente, CVCM 1,7 e 1,5 vezes a registrada no Sudeste. Em uma comparação entre os indivíduos que faziam ou não uso da HAART, observou-se aumento persistente da carga viral naqueles que não faziam uso da terapia de até 3,9 vezes em 2011. Conclusão: A abordagem apresentada neste estudo aponta a existência de aglomerados no espaço com altas concentrações. O uso do Kernel na identificação de aglomerados no espaço mostrou-se um bom instrumento para análise exploratória, possibilitando a visualização do risco em determinadas áreas geográficas sem as usuais divisões político-administrativas.

ABSTRACT: Objectives: To estimate the human immunodeficiency virus (HIV) viral load in the Brazilian population and to assess the potential impact of highly active antiretroviral therapy (HAART) in reducing new infections to build evidences and to gather information to support health policies. Methods: Spatial analysis and modeling tools were used to describe the existing patterns of the viral load density, using the Kernel method. Data on viral load and treatment were retrieved from the databases Laboratory Tests Control System (SISCEL), which contains information on the individual's history of viral load, and Medication Logistics Control System (SICLOM), which controls the dispensing of drugs used for antiretroviral therapy. Results: It was observed that the community viral load (CVL) decreased progressively from 2007 to 2011, accompanied by a decrease of more than 32% in the mean CVL (CVLM) - 22,900 copies/mL in 2007 versus 15,418 copies/mL in 2011. During this period, there was a reduction of CVLM in all regions of Brazil, although North and Northeast showed, respectively, CVLM 1.7 and 1.5 times higher than that in the Southeast region. A comparison between the individuals who underwent and who did not undergo HAART showed an increase of up to 3.9 times in 2011 in the viral load among those who did not undergo the therapy. Conclusion: The approach presented in this study indicates the existence of clusters with high concentrations. The use of Kernel in the identification of clusters proved to be a good tool for exploratory analysis, enabling the risk identification in certain geographic areas without the usual political and administrative divisions.

RESUMO

Visceral leishmaniasis (VL) is a disease of chronic evolution which could be uniformly fatal, if left untreated. Human VL was first described in the Americas in 1913 and in 1936 in Brazil. The number of VL cases in Brazil is increasing steadily in the last three decades. Medical literature highlights this change in the disease epidemiology as a recent urbanization phenomenon, with most of the cases occurring in large cities since 1981, different to that observed previously, like a typical rural endemic. The aim of this study was to create a narrative review of the evolution of VL epidemiology since its first description in Brazil. To describe the process of urbanization of VL, timeframes were created historically consistent with the scientific and public health knowledge obtained about the VL and the demographics changes in Brazil, especially considering the extensive migratory movements in the country due to political or economic events. The first phase of VL was the decades of 30-50 when industrialization triggered internal migration process from countryside to the cities; during this period VL was studied for the first time and described as a rural endemic disease with no relevance to public health. Until the second phase, between the 50s and 80s of the 20th century, demography was characterized by expansion of immigration to the large cities and increase in population density in the suburbs with poor living standards. In this period, there was an advancement in the knowledge of the transmission of the disease being described as the first case acquired in the urban environment. The third phase was characterized by the explosion of cases in Brazilian cities and consolidation of urban endemic transmission. The possibility of urban transmission has been known since the 50s; however, the current phenomenon was due to the creation of ideal conditions for the establishment of transmission cycle in Brazilian cities.

RESUMO

Zika virus is a flavivirus related to Dengue virus, yellow fever virus and West Nile virus. It is considered an emerging arbovirus transmitted by mosquitos of the genus Aedes. Its first description took place in 1947 in the Zika Forest in Uganda, isolated on Rhesus monkey used as bait to study the yellow fever virus. Sporadic cases have been detected in African countries and at the end of the 70's in Indonesia. In 2007, epidemics were described in Micronesia and other islands in the Pacific Ocean and more recently in Brazil. Clinical picture is characterized as a 'dengue-like' syndrome, with abrupt onset of fever and an early onset evanescent rash, often pruritic. Occasionally the disease has been associated with Guillain-Barré syndrome. Nevertheless, until now deaths and complications caused by the disease were not reported. The diagnosis can be performed by PCR or by IgG and IgM antibodies detection. The rapid spread of the virus and its epidemic potential are especially problematic in countries where there are the circulation of other arboviruses which imposes difficulties in the differential diagnosis and healthcare burden. Control measures are the same recommended for dengue and chikungunya which are based in health education and vector control.

O vírus Zika é um flavivírus filogeneticamente relacionado com o vírus dengue, vírus da febre-amarela e vírus do Nilo Ocidental. É considerado uma arbovirose emergente transmitida por mosquitos do género Aedes. A sua descoberta deu-se em 1947 na floresta Zika no Uganda, isolado em macaco Rhesus que servia de isco para estudo do vírus da febre-amarela. Foram detetados casos isolados em países de África e no final da década de 70 na Indonésia. A partir 2007 foram descritas epidemias na Micronésia e outras ilhas do Oceano Pacífico e, mais recentemente, no Brasil. Carateriza-se clinicamente como uma síndrome febril aguda 'tipo-dengue' com aparecimento precoce de exantema evanescente muitas vezes pruriginoso; ocasionalmente a doença tem sido associada à síndrome de Guillain-Barré. No entanto, até ao momento não foram relatadas mortes pela doença e suas complicações. O diagnóstico pode ser realizado por meio de técnica de reação em cadeia da polimerase ou por pesquisa de anticorpos IgG e IgM. A rápida disseminação do vírus e seu potencial epidémico são preocupantes especialmente em territórios com circulação de outras arboviroses pela dificuldadeno diagnóstico diferencial e na sobrecarga dos serviços de saúde. As medidas de controlo são as mesmas recomendadas para a dengue e chikungunya, baseadas em educação em saúde e controlo do vetor.

RESUMO

Health surveillance (HS) is one of the key components of the Brazilian Unified Health System (SUS). This article describes recent changes in health surveillance funding models and the role these changes have had in the reorganization and decentralization of health actions. Federal law no. 8.080 of 1990 defined health surveillance as a fundamental pillar of the SUS, and an exclusive fund with equitable distribution criteria was created in the Basic Operational Norm of 1996 to pay for health surveillance actions. This step facilitated the decentralization of health care at the municipal level, giving local authorities autonomy to plan and provide services. The Health Pact of 2006 and its regulation under federal decree No. 3252 in 2009 bolstered the processes of decentralization, regionalization and integration of health care. Further changes in the basic concepts of health surveillance around the world and in the funding policies negotiated by different spheres of government in Brazil have been catalysts for the process of HS institutionalization in recent years.

A Vigilância em Saúde (VS) é um dos componentes do Sistema Único de Saúde (SUS). Este artigo tem o objetivo de descrever as mudanças recentes no financiamento da VS e o seu papel na organização e descentralização das ações de saúde. A Lei 8080/1990 estabeleceu a VS como eixo estruturante do SUS e a criação de um teto financeiro exclusivo para as ações de VS na Norma Operacional Básica do SUS 1/96, composto por critérios equitativos, o que facilitou a descentralização das ações para a esfera municipal, permitindo ao gestor o planejamento e a continuidade das ações. O Pacto pela saúde, em 2006, e a sua regulamentação pela Portaria GM nº 3252/2009 aprofundou a descentralização, a territorialização e a integralidade da atenção. As mudanças de conceituação da VS e a política de financiamento pactuada pelas esferas de governo foram catalisadoras para o processo de institucionalização da Vigilância em Saúde (VS) nos últimos anos no Brasil.

RESUMO

Hantavirus infection is transmitted to humans by wild rodents and the most common clinical form in Brazil is the Hantavirus Pulmonary Syndrome (HPS). The first serological evidence of the disease was identified in 1990, in Recife, Pernambuco State, and later in 1993 in Juquitiba, State of São Paulo. Since then there has been a progressive increase in case notification in all regions of the country. The clinical aspects of the disease in Brazil are characterized by a prodromal phase, with nonspecific signs and symptoms of an acute febrile illness. After about three days, respiratory distress develops, accompanied by dry cough that turns progressively productive, evolving to dyspnea and respiratory failure with cardiogenic shock. Although the majority of patients receive hospital care in intensive care therapy units, case-fatality rate in Brazil ranges from 33% to 100% depending on the region. Besides it has to be added the problem of differential diagnosis with other prevalent diseases in the country, like dengue and leptospirosis. Questions about the impact of uncontrolled urbanization and other environmental changes caused by human action have been raised. Due to increasing incidence and high case-fatality, there is an urge to respond to such questions to recommend preventative measures. This article aims to review the main acquisitions in clinical and epidemiological knowledge about HPS in Brazil in the last twenty years.

RESUMO

Cytokines are molecules that act as mediators of immune response; cerebral spinal fluid (CSF) IL-6 is found in all meningeal inflammatory diseases, but IL-8 is associated with acute bacterial meningitis (ABM). A case control study was done to ascertain the discriminatory power of these cytokines in differentiating ABM from aseptic meningitis (AM); IL-6 and IL-8 CSF concentrations were tested through ELISA in samples collected from patients who underwent investigation for meningitis. Sixty patients, 18 with AM, nine with bacteriologic confirmed ABM and 33 controls, assisted in 2005 (MA and controls) and 2007 (ABM) were included. Differently from controls, IL-6 concentrations were increased both in MA and ABM patients (p < 0.05). CSF IL-8 levels were higher in ABM than in AM and controls (p < 0.05). Discriminatory power in ABM as assessed by the area under receiver operator (ROC) curve was 0.951 for IL-8, using a cut-off of 1.685 ng/dL (100% of sensitivity and 94% of specificity). The CSF concentration of both IL-6 and IL-8 are increased in the presence of meningeal inflammation, IL-8 could be an important tool to differentiate ABM from AM.

RESUMO

Cryptococcus gattii causes meningoencephalitis in immunocompetent hosts, occurring endemically in some tropical and subtropical regions. Recently, this fungus was involved in an outbreak in Vancouver Island and British Columbia (Canada). In this temperate region, the VGII type is predominant. The paper describes an autochthonous case of meningoencephalitis by C. gattii VGII in a previously health child in Rio de Janeiro, considered nonendemic region of Brazil. The fungus was identified by biochemical tests and the molecular type was determined by URA5-RFLP. The present report highlights the need for clinical vigilance for primary cryptococcal meningitis in nonendemic areas.

RESUMO

Echovirus 30 belongs to the genus Enterovirus and is widely associated with aseptic meningitis (AM) outbreaks. In Brazil epidemics due to this serotype were reported in several states but in Rio de Janeiro, before this study, it was only involved in sporadic episodes. We retrospectively collected data from AM notifications charts and enterovirus isolation database from Rio de Janeiro State Health Department (RJSHD) and Enterovirus Reference Laboratory in the year of 2005. An outbreak of AM was detected during March, April and May associated with a high cell culture isolation rate for echovirus 30 (17.4 percent). Male children with ages varying from 1 to 9 years were more affected. Of the 22 patients with confirmed echovirus 30 disease, clinical information was available in eight; fever, headache and vomiting were the most common manifestations. CSF analysis showed a typical pattern of viral infection with median of cellularity of 100 cells/mm³ and mononuclear cell predominance in 64.7 percent of the cases. The median of protein and glucose levels of 49 mg/dL and 56.5 mg/dL. The fatality rate was null. Despite its benign course and the lack of treatment options, aseptic meningitis surveillance is crucial for early identification of causative agents of outbreaks, which helps to avoid additional testing and inappropriate use of antimicrobials.

RESUMO

Echovirus 30 belongs to the genus Enterovirus and is widely associated with aseptic meningitis (AM) outbreaks. In Brazil epidemics due to this serotype were reported in several states but in Rio de Janeiro, before this study, it was only involved in sporadic episodes. We retrospectively collected data from AM notifications charts and enterovirus isolation database from Rio de Janeiro State Health Department (RJSHD) and Enterovirus Reference Laboratory in the year of 2005. An outbreak of AM was detected during March, April and May associated with a high cell culture isolation rate for echovirus 30 (17.4%). Male children with ages varying from 1 to 9 years were more affected. Of the 22 patients with confirmed echovirus 30 disease, clinical information was available in eight; fever, headache and vomiting were the most common manifestations. CSF analysis showed a typical pattern of viral infection with median of cellularity of 100 cells/mm(3) and mononuclear cell predominance in 64.7% of the cases. The median of protein and glucose levels of 49 mg/dL and 56.5 mg/dL. The fatality rate was null. Despite its benign course and the lack of treatment options, aseptic meningitis surveillance is crucial for early identification of causative agents of outbreaks, which helps to avoid additional testing and inappropriate use of antimicrobials.
