Brief summary: Fasting blood glucose is maintained by hepatic production of glucose from glycogenolysis or gluconeogenesis. In cirrhosis, glycogen storage capacity is reduced, with a consequent increase in gluconeogenesis to maintain blood glucose levels. Hypoglycaemia is particularly common during periods of prolonged nocturnal fasting. Cirrhosis can therefore be considered an 'accelerated fasting' disease. In a recent study, Honda et al. described 22% nocturnal hypoglycaemia in 105 patients analysed continuously. A previous study showed that the percentage of hypoglycaemia over the total duration of continuous blood glucose recording averaged 4%.

This gluconeogenesis could lead to a significant increase in muscle and fat catabolism, which would aggravate sarcopenia and lead to undernutrition. Undernutrition and sarcopenia are serious and severe in cirrhotic patients. Sarcopenia, present in around 45% to 67% of cirrhotic patients, is thought to lead to a significant increase in the morbidity and mortality of cirrhotic patients. Glycaemic disorders appear to play a major role in this sarcopenia. Shortening the duration of fasting, and therefore of proteolysis and lipolysis, by taking a snack in the evening, could improve nitrogen balance and glucose tolerance.

However, no study has clearly established the relationship between variations in continuous monitoring of interstitial glucose, particularly periods of nocturnal hypoglycaemia, and sarcopenia. New technologies in diabetology make it possible to obtain continuous monitoring of interstitial glucose. In addition, the use of muscle surface area at the level of the 3rd lumbar vertebra or the diameter of the psoas, obtained by scanner or MRI, combined with the use of a hand-held dynamometer to quantify muscle strength, make it easier to diagnose and assess the severity of sarcopenia and malnutrition.

The hypothesis of this work is based on the probable correlation between the time spent in hypoglycaemia (glycaemia \< 0.7 g/l) and the presence of sarcopenia responsible for undernutrition in cirrhotic patients.

If positive, the results of this descriptive pilot study could provide fundamental data for anticipating and better managing sarcopenia and glycaemic disorders. The results will enable a multi-centre randomised controlled intervention trial to be set up to optimise nutritional management of patients and thus effectively combat undernutrition in cirrhotic patients.
