ABSTRACT

ABSTRACT Herpes simplex virus (HSV) is a rare cause of acute hepatitis in patients with chronic immunosuppression, including Crohn's disease. HSV hepatitis has the propensity to cause acute liver failure and death. The presenting signs and symptoms can be nonspecific, thereby causing the diagnosis to go overlooked with inadequate management, leading to a high mortality rate. We report a case of a 31-year-old male on chronic prednisone treatment for Crohn's disease who unexpectedly died. Subsequently, an autopsy showed HSV hepatitis as the cause of death. Thus, although a rare complication, HSV hepatitis should always be kept in mind as a fatal complication in patients with acute hepatitis and chronic immunosuppression.

ABSTRACT

En la remodelación arterial, como en otros tejidos del organismo, la matriz extracelular cumple un papel importante. La complejidad en la constitución de la matriz hace de la remodelación un fenómeno difícil de reproducir experimentalmente. En el caso de las arterias es clave la modificación de la relación músculo liso-matriz que produzca el cambio en el músculo liso del fenotipo contráctil al secretor. Para que ocurran los cambios en la matriz y en el músculo liso es determinante la activación de los genes productores de las proteasas que modificarán las relaciones célula-célula y célula-matriz.
