Hepatic Encephalopathy: Insights Into the Impact of Metabolic Precipitates
Hepatic failure is a severe condition marked by the progressive or sudden loss of liver function, broadly categorized into acute liver failure (ALF), which develops within days to weeks, and chronic liver failure (CLF), which evolves over months or years. Both forms can lead to serious complications such as jaundice, impaired detoxification, portal hypertension, ascites, multi-organ dysfunction, and coagulation disorders. A significant neuropsychiatric consequence of liver failure is hepatic encephalopathy (HE), a spectrum of cognitive, motor, and behavioral abnormalities. Although elevated ammonia levels have long been implicated as a central factor in the pathogenesis of HE, emerging evidence suggests that other metabolic toxins also play critical roles. These include manganese (Mn), altered glucose metabolism, short-chain fatty acids (SCFAs), mercaptans, and gamma-aminobutyric acid (GABA). This review aims to explore the multifactorial metabolic landscape contributing to HE, highlighting the potential synergistic effects and mechanistic roles of these blood-borne precipitates. Understanding these diverse metabolic contributors may pave the way for more comprehensive diagnostic and therapeutic approaches beyond the traditional focus on ammonia.
期刊介绍:
Developmental Neurobiology (previously the Journal of Neurobiology ) publishes original research articles on development, regeneration, repair and plasticity of the nervous system and on the ontogeny of behavior. High quality contributions in these areas are solicited, with an emphasis on experimental as opposed to purely descriptive work. The Journal also will consider manuscripts reporting novel approaches and techniques for the study of the development of the nervous system as well as occasional special issues on topics of significant current interest. We welcome suggestions on possible topics from our readers.
