Infección por virus sincicial respiratorio. Reporte de casos de pacientes en área crítica pediátrica de un hospital del norte de Perú / Respiratory syncytial virus infection. Case report of patients in the critical pediatric area of a hospital in northern Perú

Introducción: El Virus sincicial respiratorio (VSR) responsable de neumonía y causa de hospitalización en áreas críticas pediátricas, puede ocasionar muertes en lactantes. Reporte de caso: Se analizaron cinco casos infrecuentes a nivel estacional en un hospital al norte de Perú durante el periodo de abril a junio del 2019, donde se observaron pacientes con neumonía causados por VSR, confirmado por inmunofluorescencia directa, radiografía de tórax y con presencia de hallazgos clínicos asociados hepatomegalia y atelectasia. De los 05 casos: 4 correspondieron a niños y una niña, en edades comprendidas de 2-7 meses, todos fueron hospitalizados, presentaron sibilancias, crepitantes y politiraje como signos prevalentes al ingreso, todos desarrollaron cuadro de neumonía severa y complicaciones, se registraron dos defunciones en menores de 6 meses, con complicaciones de sepsis, PARDS y ventilación mecánica. Conclusión: los casos presentados reflejan cuadros clínicos característicos de la enfermedad, neumonía y atelectasia en lactantes, complicaciones como SOB, PARDS y hepatomegalia.

Background: The respiratory syncytial virus (RSV) responsible for pneumonia and cause of hospitalization in critical pediatric areas, can cause deaths in infants. Report of case: Five infrequent cases were analyzed at a seasonal level in a hospital in northern Peru during the period from April to June 2019, where patients with pneumonia caused by RSV were observed, confirmed by direct immunofluorescence, chest radiography and with the presence of associated clinical findings hepatomegaly and atelectasis. Of the 05 cases: 4 correspond to boys and a girl, aged 2-7 months, all were hospitalized, presented wheezing, crackles and polytirage as prevalent signs at admission, all developed severe pneumonia and complications, were recorded two deaths in children under 6 months of age, with complications of sepsis, PARDS, and mechanical ventilation. Conclusion: the cases reflect characteristic clinical pictures of the disease, pneumonia and atelectasis in infants, complications such as SOB, PARDS and hepatomegaly.

Seroprevalence of toxoplasmosis in pregnant women and its associated factors among hospital and community populations in Lambayeque, Peru

Abstract INTRODUCTION Toxoplasmosis is a zoonosis caused by Toxoplasma gondii. This study investigated the prevalence and factors associated with toxoplasmosis among pregnant women. METHODS We followed an analytical observational study. From July 2016 to June 2017, 218 pregnant women were selected. The infection was detected through serological dosage of anti-T.gondii Immunoglobulin(Ig) M and IgG antibodies. RESULTS The seroprevalence was 35.8%; the factors associated with infection were consumption of non-drinking water, residence in an urban area, and threatened abortion during the current pregnancy. CONCLUSIONS The seroprevalence of toxoplasmosis among pregnant women is high. The risk factors are dependent on environmental determinants.

Frecuencia de leptospirosis y características socio-demográficas en pacientes febriles del norte del Perú / Leptospirosis frequency and socio-demographic characteristics associated in febrile patients from northern Perú

Indroduction: Leptospirosis is a frequent cause of febrile illness around the world, particularly in tropical and subtropical areas such as Perú. Objective: To estimate the frequency and socio-demographic characteristics associated with leptospirosis in febrile patients in northern Perú. Materials and Methods: A cross sectional study was conducted from January to December 2014 in 143 fever cases admitted to the Hospital Regional Lambayeque, Perú. Structured for socio-demographic information and sanitation questionnaire was used. Serum samples were examined to quantitatively determine the presence of IgM antibodies to leptospira using ELISA IgM. Results: The frequency was 26.6% (95% CI 19.3 to 33.8) and independently associated features were: be between 20-54 years (OR: 3.36, 95% CI 1.17 to 9, 64), work in agriculture-livestock (OR: 6.15, 95% CI 1.99 to 19.05),contact with animals (OR: 4,13, IC 95%: 1,76-9,65) and consumption of unsafe water(OR: 3,33, IC 95%: 1,49-7,43). Conclusions: This study reveals a high frequency of leptospirosis among febrile patients from northern Perú. These results indicate the need to investigate routinely leptospirosis in febrile patients, especially those exhibiting risk characteristics.

Introducción: La leptopsirosis es causa frecuente de enfermedad febril alrededor del mundo, en particular en áreas tropicales y subtropicales como Perú. Objetivo. Estimar la frecuencia de leptospirosis y características socio-demográficas asociadas en pacientes febriles del norte del Perú. Material y Métodos: Se realizó un estudio transversal entre enero y diciembre de 2014 en 143 casos febriles admitidos en el Hospital Regional Lambayeque, Perú. Se usó un cuestionario estructurado para obtener información socio-demográfica y de saneamiento. Se examinaron muestras de suero para determinar cuantitativamente la presencia de anticuerpos IgM contra leptospira usando la técnica de ELISA IgM. Resultados: La frecuencia fue de 26,6% (IC 95%: 19,3-33,8) y las características asociadas independientemente fueron: tener entre 20 y 54 años (OR: 3,36, IC 95%: 1,17-9,64), dedicarse a la agricultura/ganadería (OR: 6,15, IC 95%: 1,99-19,05), el contacto con animales (OR: 4,13, IC 95%: 1,76-9,65) y el consumo de agua no potable (OR: 3,33, IC 95%: 1,49-7,43). Conclusiones: Este estudio revela una alta frecuencia de leptospirosis entre los pacientes febriles procedentes del norte del Perú. Estos resultados indican la necesidad de investigar la leptospirosis rutinariamente como causa de enfermedad febril, especialmente entre aquellos pacientes que presentan características de riesgo.
