Los autores creen que unas 3.800 personas del Reino Unido son portadoras de la proteína priónica responsable de la enfermedad. Junto con investigadores de la Unidad de Vigilancia de le ECJ en Edimburgo y del Imperial College de Londres estudiaron 12.647 muestras de apéndices y amígdalas almacenados tras intervenciones quirúrgicas rutinarias a finales de los noventa. Tres de las muestras presentaban evidencia de acumulación de priones asociados a la vECJ. Extrapolando la cifra llegan a la de 3.800 citada anteriormente.
No obstante, sólo una de las tres muestras presenta el patrón de acumulación de priones similar al que se observa en los casos de vECJ, y añaden que la presencia de priones en los tejidos estudiados no significan necesariamente que las personas portadoras han desarrollado la enfermedad.
Si bien consideran que la cifra de posibles casos de portadores no es alarmante, creen que pone de manifiesto la necesidad de seguir estudiando en este ámbito para obtener respuestas más precisas.
