ABSTRACT

Hantavirus infection is a viral zoonotic infection borne by rodents which most letal form clinical is the Hantavirus Pulmonary Syndrome (SPH, Spanish abbreviation). The Mamore River variant originates in South America and was found in rodents without any association to human diseases. Two cases of SPH were identified in the Peruvian Amazon region in November 2011. In both cases, a molecular diagnostic testing was conducted by the Instituto Nacional de Salud from Peru. A phylogenetic analysis of a viral genome fragment and a histopathological evaluation were conducted. Both patients developed adult respiratory distress syndrome and refractory shock. A patient died and another one recovered 12 days later.

ABSTRACT

La hantavirosis es una infección viral zoonótica transmitida por roedores cuya forma clínica más letal es el síndrome pulmonar por Hantavirus (SPH). La variante río Mamoré es autóctona de Sudamérica y fue descrita en roedores sin asociarla a enfermedad en humanos. Se presenta dos casos de SPH causados por hantavirus río Mamoré en la Amazonía peruana en noviembre de 2011. En ambos casos, el diagnóstico confirmatorio fue molecular, efectuados en el Instituto Nacional de Salud de Perú. Se realizó análisis filogenético del fragmento de genoma viral y la evaluación histopatológica. Ambos pacientes evolucionaron a síndrome de distrés respiratorio del adulto y estado de choque refractario. Un paciente falleció y el otro se recuperó a los doce días.

ABSTRACT

UNLABELLED: Pneumonic plague is one of the clinical forms of plague, of low frequency and high mortality, transmitted by direct inhalation of Yersinia pestis coming from an animal or from person to person. OBJECTIVE: To describe the clinical and epidemiological characteristics of the cases of primary pneumonic plague in an outbreak in the north of Peru. MATERIALS AND METHODS: The clinical records of the confirmed cases of primary pneumonic plague presenting in an outbreak occurring in La Libertad, in July 2010, were reviewed, also the search and contact investigation was performed. RESULTS: The index case was identified, as well as three additional cases, out of these, two were nosocomial infections related to the index case. The initial clinical presentation was characterized by sudden onset of fever, chills, myalgia and chest pain, which in less than 24 hours evolved to hypotension and cyanosis. The initiation of specific treatment varied from 2 to 12 days, and cases with prompt initiation of treatment had a better clinical outcome. The lethality was 50% (2/4). CONCLUSION: Nosocomial transmission of pneumonic plague in Peru is evidenced, with severe clinical manifestations and high lethality.

ABSTRACT

La peste neumónica es una forma clínica de peste, de baja frecuencia y alta letalidad, transmitida por la inhalación directa de Yersinia pestis proveniente de un animal o de persona a persona. Objetivo: Describir las características clínicas y epidemiológicas de los casos de un brote de peste neumónica primaria humana en el norte de Perú. Materiales y Métodos. Se revisaron las historias clínicas de los casos confirmados de peste neumónica primaria presentados en un brote ocurrido en la región de La Libertad, en el mes de julio de 2010, asimismo, se efectuó la búsqueda e investigación de contactos. Resultados: Se identificó el caso Índice y tres casos adicionales, de estos últimos, dos fueron infecciones intrahospitalarias relacionadas con el caso índice. La presentación clínica inicial se caracterizó por fiebre de inicio súbito, escalofríos, mialgias y dolor torácico y evolución en menos de 24 horas a hipotensión arterial y cianosis. El inicio del tratamiento específico varió de 2 a 12 días, observándose que los casos con inicio precoz de tratamiento tuvieron un mejor resultado clínico. La lealtad fue de 50 por ciento (2/4). Conclusión: Se evidenció la transmisión intrahospitalaria de peste neumónica en el Perú con manifestaciones graves y alta letalidad.
