ABSTRACT
Resumen Antecedentes: La enfermedad de Kawasaki (EK) en lactantes bajo un año de edad es poco frecuente en la mayoría de los países. Este grupo de pacientes tienen mayor riesgo de desarrollar complicaciones cardiacas. Objetivo: Evaluar el comportamiento clínico, tratamiento empleado y pronóstico cardiaco en lactantes bajo un año de edad atendidos por EK en un hospital pediátrico de tercer nivel en la Ciudad de México. Pacientes y Métodos: Estudio retrospectivo, descriptivo, de pacientes con diagnóstico de EK desde agosto de 1995 a agosto de 2019. Se estudió la presentación clínica, los exámenes de laboratorio, el tratamiento administrado y el desarrollo de lesiones coronarias en pacientes bajo un año de edad y se comparó con pacientes mayores. Resultados: Se estudiaron 687 pacientes, 152 de ellos eran lactantes bajo un año de edad (22,1%). Hubo un mayor tiempo al diagnóstico de la EK en los lactantes menores, con un incremento de presentaciones clínicas incompletas; este grupo de pacientes desarrolló en forma más frecuente lesiones coronarias en comparación con los pacientes mayores y también tuvo un mayor porcentaje de aneurismas coronarios gigantes. Hubo dos fallecimientos en los lactantes menores, secundarios a infarto al miocardio. Conclusiones: El diagnóstico de EK en pacientes bajo un año de edad es un reto diagnóstico con presentaciones clínicas incompletas y mayor riesgo de desarrollar complicaciones cardiacas graves.
Abstract Background: Frequency of Kawasaki disease (KD) in infants is low in almost all countries. These patients are at higher risk of developing cardiac complications. Aim: To evaluate the clinical features, treatment used and cardiac outcome in infants under one year of age attending for KD in a third level pediatric hospital in Mexico City, Mexico. Methods: A cross-sectional study was conducted in our hospital from August 1995 to August 2019. We analyzed the clinical features, laboratory results, treatment used and cardiac outcomes in infants younger than one year of age and compared them with older patients. Results: We included 687 patients, 152 were younger than one year of age (22.1%). There was a delayed diagnosis in younger patients with an increased frequency of incomplete clinical presentations. Coronary artery abnormalities were most common in younger infants who also had an increased frequency of giant coronary artery aneurysms. Two patients in the younger group died in the acute phase of KD of myocardial infarction. Conclusions: Diagnosis of KD in infants younger than 1 year of age is a clinical challenge with an increased rate of incomplete clinical presentations and also an increased risk of development of severe cardiac complications.

Resumen Objetivo: Describir las manifestaciones cardiacas en la etapa aguda de la enfermedad de Kawasaki en pacientes atendidos en un hospital de tercer nivel de la Ciudad de México, México. Métodos: Estudio retrospectivo, descriptivo en pacientes con diagnóstico de enfermedad de Kawasaki de agosto de 1995 a diciembre del 2016 en el Instituto Nacional de Pediatría, México. Se estudio la demografía de los pacientes, características clínicas, tratamiento empleado y desarrollo de complicaciones cardiacas en la etapa aguda de la enfermedad. Resultados: Se estudiaron 508 casos de enfermedad de Kawasaki. La edad media al diagnóstico fue de 37.64 ± 35.56 meses. Predominio de pacientes masculinos del 65.4%, con una relación masculino/femenino de 1.88:1. La mayoría de los casos (79.2%) tuvo una presentación completa. La gammaglobulina intravenosa fue administrada en 92.4% de los casos. Veintiocho pacientes (5.5%) desarrollaron arritmias, se presentaron cambios en el segmento ST en 29 pacientes (5.6%) y 5 pacientes desarrollaron isquemia miocárdica. En el ecocardiograma inicial, 51 pacientes (9.9%) presentaron datos de miocarditis, 72 pacien- tes (14%) datos de pericarditis y 77 casos tuvieron derrame pericárdico (15%). Se detectaron alteraciones en las arterias coronarias en 169 casos (32.9%). Cuatro pacientes fallecieron en la etapa aguda de la enfermedad por complicaciones cardiacas de la enfermedad de Kawasaki. Conclusiones: En México cada vez existen más casos de enfermedad de Kawasaki con un alto porcentaje de manifestaciones cardiacas al diagnóstico. Se requiere de un mayor conocimiento de la enfermedad en México, para poder establecer cuál es la evolución cardiológica de los pacientes en el país.
Abstract Objectives: To describe the cardiac manifestations in the acute phase of patients with Kawasaki disease treated in a third level Children's hospital in Mexico City, Mexico. Methods: A cross-sectional study was conducted in patients with a diagnosis of Kawasaki disease treated in this hospital from August 1995 to December 2016. Information included patient demographics, clinical features, treatment used, electrocardiographic findings, extra-coronary echocardiographic findings, and the development of coronary artery aneurysms in the acute phase of the disease. Results: The study included 508 cases of Kawasaki disease, with a mean age at diagnosis of 37.64 ± 35.56 months (range from 2 to 200 months). Almost two-thirds (65.4%) of the patients were male, with a male/female ratio of 1.88:1. Complete Kawasaki disease was diagnosed in 79.2% of cases. Almost all cases (92.4%) received intravenous immunoglobulin. Twenty-eight patients (5.5%) developed arrhythmias, ST changes developed in 29 patients (5.6%), and 5 patients presented with ischaemic changes. In the initial echocardiographic evaluation, 51 patients (9.9%) were diagnosed with myocar- ditis, 72 patients (14.0%) with pericarditis and 77 cases (15.0%) developed pericardial effusion. Coronary artery anomalies were detected in 169 cases (32.9%). 32 cases were diagnosed as giant coronary aneurysms. Four patients died from cardiac complications in the acute phase of the disease. Conclusions: There has been an increase in the diagnosis of Kawasaki disease in Mexico. They presented with more cardiac complications than reported in literature. An increased knowledge of Kawasaki disease is required in Mexico in order to establish the cardiac outcomes of this group of patients.

In a retrospective study the authors analyzed the clinical records of 199 children ages one month to 16 years hospitalized, with the diagnosis of intestinal ascariasis, in the Instituto Nacional de Pediatría of México from 1984 to 1999. The purpose of the study was to evaluate the use of anthelmintics drugs as a risk factor of intestinal obstruction by A. lumbricoides. Two groups were made for the study: group A (n=66) of children who presented intestinal obstruction, group B (n=133) children with no complications. A comparative analysis of clinical data of both groups was made by means of chi square with Yates correction and a stratified analysis by means of chi square. Possible confusing elements were overcrowding, age and the use of antiparasitic drugs. The calculus of risk factors for intestinal obstruction by A. lumbricoides was done by means of contingency tables of 2 x 2 and odds ratio with an IC of 95 percent. The significant risk factors were included in a model of logistic regression with an impact variable consting in the presence or absence of intestinal obstruction in order to establish a multivariate model of predictive risk at level of significance of p<0,05
