RESUMO

La respuesta inflamatoria del huésped viene determinada por la virulencia del microorganismo, la duración del estímulo y el equilibrio entre la respuesta inflamatoria y la antiinflamatoria. Diversos estudios han mostrado la importancia de la genética en las infecciones graves. La respuesta inmune innata es el mecanismo que impide la invasión y propagación de microorganismos durante las primeras horas tras la infección. Cada uno de los procesos implicados en la respuesta innata puede alterarse por polimorfismos de los genes implicados, pudiendo esto resultar en una mayor susceptibilidad o resistencia a la infección. Los resultados obtenidos en los diferentes estudios genéticos no prueban de forma irrefutable el papel o la función de un gen en la patogénesis de la infección respiratoria. Sin embargo, permiten generar nuevas hipótesis, indican nuevos genes candidatos en base a su papel en la respuesta inflamatoria y proporcionan el primer paso en la comprensión de los factores genéticos subyacentes


The inflammatory response depends on several factors, including pathogenicity and duration of the stimulus, and also on the balance between inflammatory and anti-inflammatory response. Several studies have presented evidence of the importance of genetic factors in severe infections. The innate immune response prevents the invasion and spread of pathogens during the first hours after infection. Each of the different processes involved in innate immunity may be affected by genetic polymorphisms, which can result in susceptibility or resistance to infection. The results obtained in the different studies do not irrefutably prove the role or function of a gene in the pathogenesis of respiratory infections. However, they can generate new hypotheses, suggest new candidate genes based on their role in the inflammatory response, and constitute a first step in understanding the underlying genetic factors
