Alcohol, cirrosis y predisposición genética

Abstract: La cirrosis hepática es la tercera causa de muerte alrededor del mundo que es atribuible al consumo de alcohol. Más del 80% de los consumidores crónicos de alcohol desarrollan esteatosis y entre el 20% al 40% presentan otras complicaciones como fibrosis, hepatitis alcohólica y cirrosis; sin embargo, no todos los individuos con consumo crónico de alcohol desarrollan cirrosis, en parte debido al componente genético de cada individuo. El grado de actividad de las enzimas que metabolizan el alcohol está influencia… Show more

“…A satisfactory unifying mechanism for individual susceptibility, initiation, and progression of alcoholic liver injury is not available [348]. Instead, some dozens of signaling mediators and mechanistic pathways have been presented, including CYP 2E1 and other topics, which are still challenging issues in experimental and clinical alcoholic liver injury, as results are in part contradictory, rarely confirmed, or discussed by other groups [349,350,351,352,353,354,355,356,357,358,359,360,361,362,363,364,365,366,367,368,369,370,371,372,373,374]. Much emphasis has previously been placed on the role of the endoplasmic reticulum as the principal localization of CYP 2E1, and the clinical and pathogenetic importance of this microsomal CYP 2E1, which is considered to play an essential role in endoplasmic reticulum (ER) stress syn.…”

“…Three distinct enzymes are involved in the metabolism of alcohol in the liver (Figure 1), namely alcohol dehydrogenase (ADH); cytochrome P450, family 2, subfamily E, member 1 (CYP2E1); and catalase (CAT) [26][27][28][29]. ADH takes the lead in the liver and stomach, as it metabolizes 90% of ingested ethanol [30].…”

“…It is important to note that modifications in calcium signaling have been related to cell death and apoptosis [35,64,65]. • The latest hypotheses deal with neural death during forebrain maturation due to the blockade of the NMDA-glutamate receptor and the activation of GABA-A receptors [26]. Excitatory amino acids (glutamate) influence the processes of neuronal differentiation and synaptogenesis because they can modulate the organization of neuronal circuits and can opportunely regulate biochemical events related to the phenomenon of neuronal plasticity.…”

“…El alcohol causa más daño en mujeres, ya que ellas tienen más tejido graso y menor cantidad de agua, sangre y enzimas metabolizantes del alcohol, provocando que este se absorba más rápido y se metabolice más lento. Por esto, generalmente las mujeres se embriagan más fácilmente y los efectos duran más tiempo (Míguez y Permuy, 2017), así como son más propensas a desarrollar cirrosis y daño hepático (Gaviria et al, 2016).…”
