ABSTRACT

The nematode Angiostrongylus cantonensis has been reported worldwide. However, some basic questions remain unanswered about A. cantonensis in Ecuador: (1) Was the invasion of A. cantonensis in Ecuador unique, or did it occur in different waves? (2) Was this invasion as recent as historical records suggest? (3) Did this invasion come from other regions of South America or elsewhere? To address these issues, we assessed the genetic diversity of MT-CO1 gene sequences from isolates obtained in 11 of Ecuador's 24 provinces. Our Bayesian inference phylogenetic tree recovered A. cantonensis as a well-supported monophyletic group. All 11 sequences from Ecuador were identical and identified as AC17a. The haplotype AC17a, found in Ecuador and the USA, formed a cluster with AC17b (USA), AC13 (Thailand), and AC12a-b (Cambodia). Notably, all the samples obtained in Ecuadorian provinces' different geographic and climatic regions had no genetic difference. Despite the lack of genetic information on A. cantonensis in Latin America, except in Brazil, our finding differs from previous studies by its absence of gene diversity in Ecuador. We concluded that the invasion of A. cantonensis in Ecuador may have occurred: (1) as a one-time event, (2) recently, and (3) from Asia via the USA. Further research should include samples from countries neighboring Ecuador to delve deeper into this.

ABSTRACT

Introducción: La malaria continúa siendo un importante problema de salud a nivel mundial, su diagnóstico temprano y tratamiento inmediato son fundamentales para prevenir las complicaciones y la muerte. Objetivo: Reportar el caso de un paciente cubano procedente de República de Guinea, que presentó malaria complicada por Plasmodium falciparum, el cual fue hospitalizado en el Instituto de Medicina Tropical Pedro Kourí (IPK). Caso clínico: Paciente masculino, cubano, de piel negra, 63 años de edad, profesión marinero mercante. Sin antecedentes patológicos personales. Llegó al IPK en camilla, con cierto deterioro de la conciencia, debilidad generalizada, dificultad respiratoria y compromiso del ritmo diurético. Ingresó en la Unidad de Cuidados Intensivos donde recibió tratamiento con los antipalúdicos artesunato y primaquina. La parasitemia fue descendiendo en el decursar de los días. El paciente sobrevivió y egresó satisfactoriamente a los 16 días posteriores a su ingreso. Fue debidamente notificado a las autoridades del Ministerio de Salud Pública de Cuba, lo que constituye un procedimiento obligatorio del Sistema Nacional de Vigilancia de Enfermedades Transmisibles en Cuba. Conclusión: La rapidez en el diagnóstico, así como el tratamiento integral, eficaz y oportuno, fue de importancia vital y condujo a un buen desenlace de la enfermedad.


Introduction: Malaria continues to be a major health problem worldwide, its early diagnosis and prompt treatment are critical to prevent complications and death. Objective: To report the case of a Cuban patient from the Republic of Guinea, who presented with complicated Plasmodium falciparum malaria, who was hospitalized at the Institute of Tropical Medicine Pedro Kourí (IPK). Clinical case: Male patient, Cuban, black-skinned, 63 years old, occupation: merchant seaman. No personal pathological history. He arrived at the IPK on a stretcher, with some deterioration of consciousness, generalized weakness, respiratory distress and diuretic rhythm compromise. He was admitted to the Intensive Care Unit where he received treatment with the antimalarial drugs artesunate and primaquine. Parasitemia decreased over the days. The patient survived and was discharged satisfactorily 16 days after admission. This case was duly notified to the authorities of the Ministry of Public Health of Cuba, which is a mandatory procedure of the National Surveillance System of Communicable Diseases in Cuba. Conclusion: Prompt diagnosis, as well as a comprehensive, effective, and timely treatment was vital and led to a good disease outcome.

ABSTRACT

Introducción: La infección por malaria durante el embarazo es un importante problema de salud en la mayoría de las regiones tropicales. Esta condición puede tener incidencia negativa tanto en la gestante como en el feto. Objetivo: Indagar en el impacto del tratamento preventivo intermitente con el medicamento antimalárico sulfadoxina-pirimetamina en la mujer embarazada. Métodos: Se realizó una revisión bibliográfica en la base de datos Medline/Pub Med y en artículos relevantes relacionados al tema de los últimos cinco años. Además, se tomó como referencia las guías para el tratamiento de malaria de la Organización Mundial de la Salud, verisón 2016-2017. Análisis y síntesis de los resultados: Durante el período 2015-2017 no se lograron avances significativos en la reducción del número de enfermos palúdicos. No obstante, se señala la anemia como causa de mortalidad en el curso de la malaria. También, se destacan los nuevos enfoques y compromisos para reducir la morbilidad atribuible al paludismo en la mujer embarazada en sus tres vertientes: tratamiento eficaz de los casos de paludismo, el uso de mosquiteros tratados con insecticidas, y la utilización del tratamiento preventivo intermitente con el antimalárico sulfadoxina-pirimetamina a partir del segundo trimestre del embarazo. La indicación de este tratamiento inlcuye mínimo dos dosis del fármaco antipalúdico, con un intervalo de un mes entre cada dosis, con independencia de que las embarazadas muestren o no síntomas de la enfermedad. Conclusiones: Esta intervención para prevenir el paludismo en el embarazo es una cuestión prioritaria en la iniciativa de salud materna, infantil y reproductiva; además, ayuda a mejorar y aumentar la cobertura de las medidas de control de esta enfermedad durante la gestación(AU)


Introduction: Malaria infection during pregnancy is an important health problem in most tropical regions. This condition may have a negative incidence on pregnant women and fetuses. Objective: Inquire into the effect of the intermittent preventive treatment with the malarial sulfadoxine / pyrimethamine in pregnant women. Methods: A bibliographic review was conducted in the database Medline / PubMed and in relevant papers about the topic published in the last five years. The Guidelines for the Treatment of Malaria 2016-2017 of the World Health Organization were also used as reference. Analysis and synthesis of results: Significant progress was not achieved in reducing the number of malaria patients in the period 2015-2017. However, anemia is reported as the cause of mortality during the course of malaria. New approaches and commitments are proposed to reduce malaria-related morbidity among pregnant women, namely effective treatment of malaria cases, use of insecticide-treated mosquito nets, and intermittent preventive treatment with the antimalarial sulfadoxine / pyrimethamine as of the second quarter of pregnancy. Indication of this treatment includes at least two doses of the malarial, with a separation of one month between the doses, regardless of whether the pregnant women have symptoms of the disease. Conclusions: The intervention to prevent malaria during pregnancy is a first-priority aspect of the mother, child, reproductive health initiative. It also helps improve and broaden the coverage of measures for the control of this disease during pregnancy(AU)
