RESUMO
La tos crónica (TC), o tos que perdura más de 8 semanas, ha merecido un interés creciente en los últimos años debido a los avances producidos que han motivado un cambio de visión respecto a la clásica tríada diagnóstica y terapéutica en vigor desde la década de los setenta. Unos resultados no óptimos en el tratamiento que alcanza los dos tercios de casos, junto a una nueva concepción de la TC como síndrome de hipersensibilidad con 2 polos, periférico y central, similares al dolor crónico, ocasionan que se contemple este problema tan frecuente en la práctica clínica de una nueva manera. Los receptores periféricos de la TC siguen teniendo vigencia bajo la tríada diagnóstica; sin embargo, tanto la convergencia de estímulos como la hipersensibilidad adquirida a nivel del sistema nervioso central son hechos que tienen una repercusión clave en el éxito del tratamiento
Chronic cough (CC), or cough lasting more than 8 weeks, has attracted increased attention in recent years following advances that have changed opinions on the prevailing diagnostic and therapeutic triad in place since the 1970s. Suboptimal treatment results in two thirds of all cases, together with a new notion of CC as a peripheral and central hypersensitivity syndrome similar to chronic pain, have changed the approach to this common complaint in routine clinical practice. The peripheral receptors involved in CC are still a part of the diagnostic triad. However, both convergence of stimuli and central nervous system hypersensitivity are key factors in treatment success
