Investigadores de la Universidad de Wisconsin-Madison (Estados Unidos) estudiaron la relación entre los niveles de cotinina sérica –sustancia que se crea por la disgregación de la nicotina en el organismo- y la pérdida auditiva en 197 pacientes con pérdida de audición recién diagnosticada y en 294 controles.
Los resultados muestran que no se encontró ninguna asociación significativa entre los niveles de cotinina y la pérdida de audición y, por lo tanto, con concuerdan con los de una investigación anterior que atribuía la pérdida auditiva al tabaquismo y a la exposición al humo del tabaco en el ambiente.
