Hepatic encephalopathy (HE) is a serious complication of cirrhosis. Clinical trials have consistently shown that L-ornithine-L-aspartate significantly improves HE symptoms. Health-related quality of life (HR-QOL) is impaired in HE patients and represents an important outcome measure for therapeutic intervention. The

Hepatic encephalopathy continues to be a major clinical problem and the current decade has not witnessed major therapeutic breakthroughs in this area. L-ornithine-l-aspartate (LOLA) is not frequently used as there are still some reservations about its benefits. The present study

Minimal hepatic encephalopathy (MHE) impairs daily functioning and health-related quality of life (HRQoL). The modalities of treatment of MHE have not been adequately studied. To compare lactulose, probiotics, and L-ornithine L-aspartate (LOLA) in treatment of MHE and effect on HRQoL
Patrícia Coelho de Soárez et al.
Arquivos de gastroenterologia, 46(3), 241-247 (2009-11-18)
Experimental and clinical studies suggest that LOLA may have a favorable influence on hepatic encephalopathy due to the effect on the reduction of ammonia, and improvement of the symptoms and laboratory findings. To evaluate and to critically analyze the efficacy

Hepatic encephalopathy complicates the course of both acute and chronic liver disease and its treatment remains an unmet clinical need. Ammonia is thought to be central in its pathogenesis and remains an important target of current and future therapeutic approaches.
