ABSTRACT

Helicobacter pylori es un carcinógeno tipo I resistente a múltiples antibióticos y con alta prioridad en salud pública. La infección por este microorganismo está influenciada por una interacción compleja entre la genética del huésped, el entorno y múltiples factores de virulencia de la cepa infectante. Afecta al 50 % de la población mundial, provocando afecciones gastroduodenales graves, la mayoría de forma asintomática. El 20 % de los individuos con H. pylori pueden desarrollar a través del tiempo lesiones gástricas preneoplásicas y el 2 % de ellos un cáncer gástrico. Las manifestaciones clínicas gastrointestinales y extragastrointestinales están asociadas a su virulencia y a la respuesta del sistema inmunológico con la liberación de citosinas proinflamatorias, tales como TNF-alfa, IL-6, IL-10 e IL-8, causantes de inflamación aguda y crónica. Múltiples factores de virulencia han sido estudiados como el gen A asociado a la citotoxina (CagA) y la citotoxina vacuolante (VacA), los cuales juegan un rol importante en la aparición del cáncer gástrico. Dada la resistencia cada vez mayor a los antibióticos utilizados, las líneas de estudio en el futuro inmediato deben estar encaminadas en establecer la utilidad de los nuevos antibióticos y la determinación de profagos colombianos en todo el país. Esta revisión tiene como objetivo hacer una puesta al día sobre las características del H. pylori, los mecanismos patogénicos, genes de virulencia, su asociación con el mayor riesgo de cáncer gástrico, farmacorresistencia microbiana y su erradicación.


Helicobacter pylori is recognized as a class I carcinogen resistant to multiple antibiotics and with high priority in public health. The infection caused by this microorganism is influenced by a complex interaction between host genetics, environment, and multiple virulence factors of the infecting strain. It affects 50% of the world population, causing severe gastroduodenal conditions, most of them asymptomatic. Through time, 20% of individuals with H. pylori may develop preneoplastic gastric lesions and 2% of them develop gastric cancer. The gastrointestinal and extra-gastrointestinal clinical manifestations are associated with its virulence and the response of the immune system with the release of pro-inflammatory cytokines, such as TNF-alpha, IL-6, IL-10 and IL-8, which cause acute and chronic inflammation. Multiple virulence factors have been studied, such as cytotoxin-associated gene A (CagA) and vacuolating cytotoxin A (VacA), which play an important role in the development of gastric cancer. Due to the increasing antibiotics resistance, the research in the immediate future should be aimed at establishing the usefulness of the new antibiotics and the determination of Colombian prophages throughout the country. This paper aims to update the characteristics of H. pylori, its pathogenic mechanisms, virulence genes, its association with the increased risk of gastric cancer, microbial drug resistance, and eradication.

ABSTRACT

Resumen Este artículo describe el inicio de las preocupaciones sanitarias vinculadas a las epidemias ocurridas durante el siglo XX en La Pampa, provincia argentina. Las epidemias, como las de la viruela, fueron un estímulo para estas políticas que frecuentemente tuvieron origen en Buenos Aires, la capital del país. El contagio de muchas epidemias dependía de carencias de infraestructura: agua, desagüe y desecho adecuado de basuras, de la ausencia de un número suficiente de trabajadores de salud, de la presencia de vectores transmisores de enfermedades como los mosquitos y, en última instancia, de la pobreza. La experiencia histórica descrita en este texto resalta la importancia de analizar el impacto del SARS-CoV-2 más allá de las grandes ciudades.


Abstract This article describes the emergence of health concerns relating to the epidemics that occurred during the twentieth century in La Pampa, a province in Argentina. Epidemics such as smallpox drove such policies, which frequently originated in Buenos Aires, the country's capital. The spread of many epidemics was due to shortages: water, sewage and adequate refuse disposal, an insufficient number of health care workers, the presence of disease transmission vectors such as mosquitos, and, ultimately, poverty. The historical experience described in this text highlights the importance of analyzing the impact of SARS-CoV-2 beyond the big cities.

ABSTRACT

La malaria o paludismo sigue representando una carga de enfermedad para las comunidades de los diferentes territorios de Colombia, de los cuales Chocó, Nariño, Córdoba y Antioquia son los departamentos donde más casos se notifican (el 73 % de 77 172 casos de malaria no complicada en 2019); además, en el país se informaron 1342 casos graves (1). El Ministerio de Salud de Colombia se adhirió a la Iniciativa Regional para la Eliminación de la Malaria (IREM), creada en 2014. En diciembre de 2019, esta iniciativa priorizó acciones en 12 municipios de Chocó, Nariño y Valle del Cauca. Sin embargo, la situación social en los territorios indica que no están dadas las condiciones que permitan este logro en el país.


Malaria continues to represent a burden of disease for communities in the different territories of Colombia, of which Chocó, Nariño, Córdoba and Antioquia are the departments where most cases are reported (73% of 77 172 cases of uncomplicated malaria in 2019); in addition, 1342 severe cases were reported in the country (1). The Colombian Ministry of Health joined the Regional Initiative for the Elimination of Malaria (IREM), created in 2014. In December 2019, this initiative prioritized actions in 12 municipalities in Chocó, Nariño and Valle del Cauca. However, the social situation in the territories indicates that the conditions are not in place to allow this achievement in the country.

ABSTRACT

Resumen Helicobacter pylori (H. pylori) es un bacilo gramnegativo microaerófilo, capaz de colonizar la mucosa gástrica. Este microorganismo infecta a más de la mitad de la población mundial, por lo que se ha convertido en la infección bacteriana más común. La prevalencia de la infección y de las enfermedades asociadas a ella es alta, sobre todo en países en vías de desarrollo. El tratamiento recomendado para la erradicación es la triple terapia; sin embargo, su eficacia ha disminuido por el desconocimiento del patrón de susceptibilidad bacteriano por parte del personal médico y dada la aparición de cepas resistentes. La resistencia en H. pylori se asocia con la capacidad de adaptación de la bacteria a ambientes hostiles y al uso de los antibióticos. En Colombia, existen reportes acerca de que H. pylori presenta resistencia a amoxicilina, metronidazol, claritromicina, furazolidona, levofloxacina y tetraciclina. Los estudios del patrón de susceptibilidad determinaron que la frecuencia de resistencia de H. pylori es variable y demuestran la falta de datos en la mayoría del territorio del país. Sobre la base de lo anterior, el objetivo de esta revisión es describir los porcentajes de resistencia de H. pylori a los antibióticos amoxicilina, metronidazol, claritromicina, furazolidona, levofloxacina y tetraciclina, usados en el tratamiento de la infección en los estudios realizados en Colombia.


Abstract Helicobacter pylori (H. pylori) is a microaerophilic gram-negative bacillus that colonizes the gastric mucosa. It infects more than half the world's population, making it the most common bacterial infection. The prevalence of infection and associated diseases is high in developing countries. The recommended treatment for its eradication is triple therapy; however, its efficacy has decreased due to the lack of knowledge of the bacterial susceptibility pattern among the medical staff and the emergence of resistant strains. H. pylori susceptibility is associated with the bacteria's ability to adapt to hostile environments and the use of antibiotics. In Colombia, it has been reported that H. pylori is resistant to amoxicillin, metronidazole, clarithromycin, furazolidone, levofloxacin, and tetracycline. Studies on the susceptibility pattern have determined that the frequency of H. pylori susceptibility is variable and demonstrate the lack of data in most of the Colombian territory. With this in mind, the objective of this review is to describe the percentage of resistance to amoxicillin, metronidazole, clarithromycin, furazolidone, levofloxacin and tetracycline, which are used for the treatment of H. pylori infection, according to studies conducted in Colombia.

ABSTRACT

Abstract From its inception, in 1948, the World Health Organization made control of malaria a high priority. Early successes led many to believe that eradication was possible, although there were serious doubts concerning the continent of Africa. As evidence mounted that eradicating malaria was not a simple matter, the malaria eradication programme was downgraded to a unit in 1980. Revived interest in malaria followed the Roll Back Malaria Initiative adopted in 1998. This article presents an historical account of the globally changing ideas on control and elimination of the disease and argues that insufficient attention was paid to strengthening health services and specialized human resources.


Resumo Desde sua origem, em 1948, a Organização Mundial da Saúde priorizou o controle da malária. Os primeiros êxitos induziram à crença na viabilidade da erradicação, apesar de sérias dúvidas quanto ao continente africano. À medida que se somavam comprovações de que a erradicação da malária não seria simples, o projeto com essa finalidade foi rebaixado a uma unidade em 1980. O reavivamento do interesse na malária ocorreu após a iniciativa Roll Back Malaria, criada em 1998. Este artigo apresenta um panorama histórico das mudanças nas ideias, em âmbito global, ligadas ao controle e à eliminação da doença e defende a tese de que a atenção dada ao fortalecimento dos serviços de saúde e a recursos humanos especializados foi insuficiente.

ABSTRACT

A más de cuatro meses de la pandemia que azota al planeta, existe la urgente necesidad de proyectar cómo la transmisión del nuevo SARS-CoV-2 se desarrollará en los meses venideros. En el interés de modelar el comportamiento del SARS-CoV-2 en la República Bolivariana de Venezuela, desde el Observatorio Nacional de Ciencia, Tecnología e Innovación (ONCTI), realizamos análisis estadísticos a objeto de pronosticar con base en los valores de las series de tiempo de contagios de la Covid-19 de procedencia comunitaria, la Estimación Promedio de Contagios Comunitarios. Dichos análisis han permitido evidenciar que la inédita dinámica de propagación de esta pandemia dependerá de la estacionalidad, la duración en encontrarse una vacuna de inmunidad y de los otros factores como, por ejemplo, la erradicación de procedencia de los contagios de orígenes transnacionales o importados. De allí que, utilizando datos que reflejan el comportamiento del SARS-CoV-2 durante los primeros 120 días de pandemia en la República Bolivariana de Venezuela, medimos cómo estos factores afectan la transmisión comunitaria. Para ello construimos un modelo matemático que permitió observar el comportamiento de la transmisión de SARS-CoV-2; y proyectamos qué tan recurrentes serán los brotes de SARS-CoV-2 durante las próximas 3 semanas, los cuales probablemente ocurrirán después del brote de la ola pandémica inicial(AU)


More than four months after the start of the pandemic that plagues the planet, there is an urgent need to project how the transmission of the new SARS-CoV-2 will develop in the upcoming months. Intending to model the behavior of SARS-CoV2 in the Bolivarian Republic of Venezuela, the Observatorio Nacional de Ciencia y Tecnologia (ONTIC) carried out statistical analysis to forecast based on the values of the time series of Covid-19 infections of communitarian origin, the Estimate Average of Community Contagions. These analyzes have shown that the unprecedented spread's dynamics of this pandemic will depend on seasonality, the finding of a vaccine, and other factors such as, for example, the eradication of origin of contagions of transnational or imported origin. Hence, using data that reflects the behavior of SARS-CoV2 during the first 120 days of the pandemic in the Bolivarian Republic of Venezuela, we measure how these factors affect communitarian transmission. To do this, we built a mathematical model that allowed us to observe the behavior of SARS-CoV-2 transmission, projecting how recurrent outbreaks of SARS-CoV-2 will appear over the next 3 weeks, which are likely to occur after the first wave of the pandemic(AU)

ABSTRACT

Introducción: El helminto Angiostrongylus cantonensis es un parásito habitual en los pulmones de la rata y puede ocasionar meningoencefalitis eosinofílica en el hombre cuando se pone en contacto con las larvas por ingestión accidental. En Cuba es endémico y el riesgo de contraerlo aumenta con la entrada del caracol gigante africano en el país. Objetivo: Describir las acciones desarrolladas por las autoridades sanitarias locales para el control del caracol gigante africano entre 2016 y 2018 y la aparición de un paciente en 2018 con meningoencefalitis eosinofílica causada por Angiostrongylus cantonensis vinculado epidemiológicamente con la presencia de este caracol. Métodos: Se realizó un estudio cualitativo a partir de un grupo focal con el que se trabajó ante la aparición del caracol gigante africano en un área de salud del municipio San Miguel del Padrón. Se realiza una encuesta semi-estructurada. Resultados: Se trazaron las estrategias para la erradicación de la especie invasora a partir de un trabajo comunitario. Dos años después, se observa nuevamente el caracol gigante africano y un paciente con meningoencefalitis eosinofílica epidemiológicamente asociado a Angiostrongylus cantonensis. Conclusiones: Las acciones realizadas entre 2016 y 2018 resultaron ser insuficientes por el nuevo avistamiento del caracol en el área, con el agravante de encontrar un paciente con meningoencefalitis eosinofílica epidemiológicamente asociado con el molusco(AU)


Introduction: Helmint Angiostrongylus cantonensis is a natural parasite in the lungs of ratas. Ocassionally it can produced an eosinophilic meningoencephalitis in men by larvae accidental ingestion. Methods: A qualitative study was performed from a focal group by a semi-structural survey in a health area from San Miguel del Padrón municipality. Objectives: To describe the actions developed by the local sanitarian authorities for the control of African giant snails between 2016 and 2018 and the appearance of a patient suffering from eosinophilic meningoencephalitis due to Angiostrongylus cantonensis linked to the presence of this snail. Results: It has been established an eradication strategy for the elimination of this invasive species based on a community work. Two years later, it was observed again the giant African snail in the area with a patient suffering from Angiostrongylus cantonensis eosinophilic meningoencephalitis epidemiologically associated. Conclusions: The 2016 actions were not efficient due to the emerging vector and the further finding of a patient linked with the parasite(AU)

ABSTRACT

O objetivo deste artigo é rever o "estado da arte" dos avanços, obstáculos e estratégias para atingir a erradicação global da pólio. As ações de controle da poliomielite iniciaram na década de 1960 com o advento das duas vacinas antipoliomielíticas, a vacina oral da pólio (VOP) e a vacina inativada da pólio (VIP). No período de 1985 a 2020, são implementadas estratégias para atingir a meta de erradicação do poliovírus selvagem (WPV). Após o sucesso da interrupção da transmissão autóctone do WPV na região da Américas, foi lançada a meta da erradicação global. Descrevemos o processo de erradicação em quatro tempos: (1) O advento das vacinas VIP e VOP iniciou a era do controle da poliomielite; (2) A utilização massiva e simultânea da VOP teve impacto significativo sobre a transmissão do poliovírus selvagem no final da década de 1970 no Brasil; (3) Políticas públicas (nacionais e internacionais) decidem pela erradicação da transmissão autóctone do poliovírus selvagem nas Américas e definem as estratégias epidemiológicas para interromper a transmissão; e (4) A implantação das estratégias de erradicação interrompeu a transmissão autóctone do WPV em quase todas as regiões do mundo, exceto no Paquistão e Afeganistão, onde, em 2020, cadeias de transmissão do WPV1 desafiam as estratégias de contenção do vírus. Por outro lado, a persistência e a disseminação da circulação do poliovírus derivado da VOP, em países com baixa cobertura vacinal, somadas às dificuldades para substituir a VOP pela VIP constituem, atualmente, os obstáculos para a erradicação a curto prazo. Finalmente, discutimos as estratégias para superar os obstáculos e os desafios na era pós-erradicação.

Por otro lado, la persistencia y la diseminación de la circulación del virus de la polio, derivado de la VOP, en países con baja cobertura de vacunas, sumadas a las dificultades para substituir la VOP por la VIP constituyen, actualmente, los obstáculos para la erradicación a corto plazo. Finalmente, discutimos las estrategias para superar los obstáculos y los desafíos en la era poserradicación.


This article's objective is to review the "state of the art" in the progress, obstacles, and strategies for achieving global polio eradication. Poliomyelitis control measures began in the 1960s with the advent of two vaccines, the oral polio vaccine (OPV) and the inactivated polio vaccine (IPV). From 1985 to 2020, strategies were implemented to reach the goal of eradication of wild poliovirus (WPV). Following the success with the interruption of indigenous WPV transmission in the Americas, the goal of global eradication was launched. We describe the process of eradication in four historical stages: (1) The advent of the inactivated and oral polio vaccines launched the age of poliomyelitis control; (2) The massive and simultaneous use of OPV had a significant impact on WPV transmission in the late 1970s in Brazil; (3) Domestic and international public policies set the goal of eradication of indigenous WPV transmission in the Americas and defined the epidemiological strategies to interrupt transmission; and (4) The implementation of eradication strategies interrupted indigenous WPV transmission in nearly all regions of the world except Pakistan and Afghanistan, where in 2020 the WPV1 transmission chains have challenged the strategies for containment of the virus. Meanwhile, the persistence and dissemination of circulation of OPV-derived poliovirus in countries with low vaccination coverage, plus the difficulties in replacing OPV with IPV, are currently the obstacles to eradication in the short term. Finally, we discuss the strategies for overcoming the obstacles and challenges in the post-eradication era.

ABSTRACT

Due to the successful implementation of measles and rubella elimination strategies, Mexico announced the interruption of endemic transmission of measles in 1996 and that of rubella in 2008. After a verification process, the region of the Americas was declared free of rubella and congenital rubella syndrome in 2015 and of measles in 2016. In order to maintain the elimination status in Mexico, it is essential to continue laboratory surveillance within the framework of the Global Measles and Rubella Laboratory Network. The Institute of Epidemiological Diagnosis and Reference, through the National Network of Public Health Laboratories, guarantees timely and reliable results in view of the possible reintroduction of these and other emerging pathogens.

ABSTRACT

RESUMEN La infección por helicobacter pylori afecta aproximadamente al 50% de la población mundial, es causante de gastritis crónica, úlcera péptica, cáncer gástrico y linfoma del tejido linfoide asociado a la mucosa. Desde su descubrimiento, la erradicación ha sido uno de los más importantes retos en Gastroenterología. En muchos países se desconoce la prevalencia de resistencia primaria del microorganismo a los diferentes antibióticos que empíricamente se utilizan, y por no realizar pruebas de rutina que verifican su erradicación en la práctica diaria, se ignora la efectividad de los esquemas prescritos. El incremento progresivo de la resistencia a la claritromicina y metronidazol, unido a una ausencia de antibioticoterapia alternativa, desafía la capacidad para eliminar de manera efectiva a ésta bacteria. El subcitrato de bismuto ha resurgido y su adición en la terapia ha permitido aumentar las tasas de curación por encima del 90%. Actualmente se invoca que para mejorar la eficacia en el tratamiento se debe combinar una supresión potente del ácido gástrico en tratamientos combinados cuádruples con una duración de 14 días, para la mayoría de los casos. La adherencia al tratamiento es crucial para obtener buenos resultados terapéuticos.


ABSTRACT The infection for helicobacter pylori affects approximately to the world population's 50%, it is causing of chronic gastritis, peptic ulcer, gastric cancer and linfoma associated to the mucous one. From their discovery, the eradication has been one of the most important challenges in Gastroenterología. In many countries the prevalencia of primary resistance is ignored from the microorganism to the different antibiotics that empirically they are used, and for not carrying out routine tests that verify its eradication in the daily practice, the effectiveness of the prescribed outlines it is ignored. The progressive increment of the resistance to the claritromicina and metronidazol, together to an absence of alternative antibioticotherapy, challenges the capacity to eliminate from an effective way to this bacteria. The bismuth subcitrato has resurged and its addition in the therapy has allowed to increase the cure rates above 90%. At the moment it is invoked that to improve the effectiveness in the treatment, that is should combine a potent suppression of the gastric acid in combined quadruple treatments with a duration of 14 days, for most of the cases. The adherence to the treatment is crucial to obtain therapeutic good results.

ABSTRACT

Mozambique has historically been one of the countries with the highest malaria burden in the world. Starting in the 1960s, malaria control efforts were intensified in the southern region of the country, especially in Maputo city and Maputo province, to aid regional initiatives aimed to eliminate malaria in South Africa and eSwatini. Despite significant reductions in malaria prevalence, elimination was never achieved. Following the World Health Organization's renewed vision of a malaria­free­world, and considering the achievements from the past, the Mozambican National Malaria Control Programme (NMCP) embarked on the development and implementation of a strategic plan to accelerate from malaria control to malaria elimination in southern Mozambique. An initial partnership, supported by the Bill and Melinda Gates Foundation and the La Caixa Foundation, led to the creation of the Mozambican Alliance Towards the Elimination of Malaria (MALTEM) and the Malaria Technical and Advisory Committee (MTAC) to promote national ownership and partner coordination to work towards the goal of malaria elimination in local and cross­border initiatives. Surveillance systems to generate epidemiological and entomological intelligence to inform the malaria control strategies were strengthened, and an impact and feasibility assessment of various interventions aimed to interrupt malaria transmission were conducted in Magude district (Maputo Province) through the "Magude Project". The primary aim of this project was to generate evidence to inform malaria elimination strategies for southern Mozambique. The goal of malaria elimination in areas of low transmission intensity is now included in the national malaria strategic plan for 2017­22 and the NMCP and its partners have started to work towards this goal while evidence continues to be generated to move the national elimination agenda forward.

ABSTRACT

ABSTRACT Introduction and aim: Hepatitis C is a key challenge to public health in Brazil. The objective of this paper was to describe the Brazilian strategy for hepatitis C to meet the 2030 elimination goal proposed by World Health Organization (WHO). Methods: A mathematical modeling approach was used to estimate the current HCV-infected Brazilian population, and to evaluate the relative costs of two different scenarios to address HCV disease burden in Brazil: (1) if no further changes are made to the HCV treatment program in Brazil; (2) where the WHO targets for 2030 elimination are met through diagnosis and treatment efforts peaking before 2024. Results: An anti-HCV prevalence of 0.53% was calculated for the total population. It was estimated that the number of HCV-RNA+ individuals in Brazil in 2017 was 632,000 (0.31% of the population). Scale-up of treatment and diagnosis over time will be necessary in order to achieve WHO targets beginning in 2018. Direct costs (diagnostic, treatment and healthcare costs) are projected to increase significantly during the scale-up of treatment and diagnosis in the initial years of the intervention scenario, but then fall below the base case on an annual basis by 2025-2036, once HCV is eliminated, due to health sectors savings from the prevention of HCV liver-related morbidity and mortality. Conclusion: Achieving the WHO targets is technically feasible in Brazil with a scale-up of treatment and diagnosis over time, beginning in 2018.
