Resumen
En la sepsis se activa la cascada in amatoria y se desencadenan múltiples procesos siopatológicos. Uno de esos procesos es la producción de especies reactivas de oxígeno (ROS). Se han descrito diferentes fármacos, como la N-acetilcisteína (NAC), para reducir los niveles de ROS, pero ningún trabajo ha avalado su uso en la sepsis. Este estudio investigó la relación entre ROS y daño renal, generalmente presente en la sepsis, y su posible tratamiento con NAC en ratas. Se utilizaron ratas Sprague Dawley machos. Los animales se dividieron en dos grupos, uno recibió 150 mg/kg de NAC y el otro no. Además, cada grupo se dividió en 4 subgrupos (control, laparotomía, sepsis y sepsis y NAC). Se midieron la creatinina sérica y las ROS. Los subgrupos sépticos tuvieron niveles más altos de ROS que los controles y NAC no disminuyó esos niveles. No hubo diferencias en los niveles de ROS entre los subgrupos (tratados y no tratados con NAC), pero los niveles de creatinina fueron más altos. Se observó una correlación débil entre ROS y los niveles de creatinina y la administración de NAC fue un factor independiente para aumentar los niveles de creatinina. Se observó una correlación entre los niveles de ROS y la creatinina. NAC no redujo los niveles de ROS, pero aumentó los niveles de creatinina. Concluimos que la administración de NAC no mejoró los niveles de ROS y disminuyó la función renal en ratas sépticas. Hubo una correlación débil entre ROS y los niveles de creatinina, lo que demuestra que otros factores pueden modi car la función renal, como la administración de NAC, que fue un factor independiente para la disminución de la función renal medida por la creatinina sérica.
In sepsis, the entire in ammatory cascade is activated and multiple pathophysiological processes are triggered. One such process is the production of reactive oxygen species (ROS). Different drugs, such as N-acetylcysteine (NAC), have been described to reduce ROS levels, but no work has endorsed their use in sepsis. This study investigated the relationship between ROS and renal damage usually present in sepsis and its possible treatment with NAC in rats. Male Sprague Dawley rats were used. The animals were divided into two groups, one received 150 mg/kg of NAC and the other did not. In addition, each group was divided into 4 subgroups (control, laparotomy, sepsis, and sepsis and NAC). Serum creatinine and ROS were measured. The septic subgroups had higher levels of ROS than controls and NAC did not decrease those levels. There was no difference in ROS levels between subgroups (treated and not treated with NAC), but creatinine levels were higher. A weak correlation was observed between ROS and creatinine levels and NAC administration was an independent factor for increasing levels of creatinine. A correlation was observed between ROS levels and creatinine. NAC did not lower ROS levels but increased creatinine levels. We conclude that the administration of NAC did not improve ROS levels and decreased kidney function in septic rats. There was a weak correlation between ROS and creatinine levels, showing that other factors can modify kidney function, such as NAC administration which was an independent factor for decreasing renal function measured by serum creatinine.
