Sarcopenia and Sarcopenic Obesity Are Prognostic Factors for Overall Survival in Patients with Cirrhosis.

OBJECTIVE: Although the prognosis is known to be poor in cirrhosis patients associated with sarcopenia, the relationships among skeletal muscle, visceral fat, and the liver have not yet been thoroughly investigated. Therefore, the prognosis and its associations with body composition and the severity of liver disease were examined in patients with cirrhosis. METHODS: The skeletal muscle mass and visceral fat area were measured in 161 patients with cirrhosis, the effects of body composition on the prognosis were analyzed, and any factors that contribute to changes in body composition were assessed. RESULTS: During the mean observation period of 1,005 days, 73 patients died. Patients with sarcopenia or sarcopenic obesity had a poor prognosis, and this difference was pronounced in the subset of patients classified as Child-Pugh class A. A decreased skeletal muscle mass was strongly correlated with decreased serum albumin levels. Sarcopenia is a common feature of advanced cirrhosis, and transitions were observed from normal body composition to sarcopenia and from obese to sarcopenic obesity. CONCLUSION: The body composition is a prognostic factor for cirrhosis, and a better body composition may be advantageous for obtaining a long-term survival in patients with cirrhosis.

Nutrition therapy using a multidisciplinary team improves survival rates in patients with liver cirrhosis.

OBJECTIVES: Very few reports thus far have clinically elucidated the advantages of a nutrition support team (NST) in the field of liver diseases. The present study retrospectively analyzed whether nutrition therapy for liver cirrhosis (LC), performed by a multidisciplinary team that includes registered dieticians, improves survival rates. METHODS: In study 1, we compared survival rates between two groups of patients with LC to elucidate the effects of nutrition management by registered dieticians. The first group was comprised of 101 patients that received no dietary counseling from a dietician, and the second group was comprised of 133 patients that received nutritional counseling following nutrition assessment. In study 2, we split the patients who received nutritional counseling in study 1 into two groups and compared their survival rates with the objective of investigating the effects of a multidisciplinary team approach on survival rate. The first group was comprised of 51 patients that, in addition to regular nutritional counseling given by a dietician, regularly attended courses on liver disease given every 3 to 6 mo. The second group was comprised of 82 patients that did not attend the liver-disease courses. RESULTS: During study 1, 34 patients in the first group and 20 patients in the second group died, representing a significant difference (P < 0.05). This difference was even more pronounced in the subset of patients classified as Child-Pugh class A (P < 0.01), but no differences were seen among patients in classes B and C (P = 0.378). During study 2, four patients in the first group and 15 patients in the second group died, representing a significant difference (P < 0.05). CONCLUSIONS: This study showed that nutritional intervention using a multidisciplinary team during the treatment of LC improves survival rates and quality of life of the patients.

Visceral fat volume predicts new-onset type 2 diabetes in patients with chronic hepatitis C.

Ninety seven patients with chronic hepatitis C (CHC) and 72 with non-alcoholic fatty liver disease (NAFLD) were enrolled. Increased visceral fat area (VFA) was associated with high values of HbA1c. The variables associated with a high risk of new-onset diabetes had a VFA>101 cm(2) in CHC, but not in NAFLD.

Restriction of calorie and iron intake results in reduction of visceral fat and serum alanine aminotransferase and ferritin levels in patients with chronic liver disease.

AIM: To clarify the impact of visceral fat on chronic liver diseases such as non-alcoholic fatty liver disease (NAFLD) and hepatitis C, we investigated the effects of lifestyle modifications on the amount of visceral fat, liver biochemistry and serum ferritin levels in patients with liver disease. METHODS: Eighty-two patients (NAFLD, n = 37; hepatitis C, n = 45) were advised to adopt lifestyle modifications, including dietary changes and exercise, and these were maintained for 6 months. Bodyweight, percentage of body fat, visceral fat area (VFA) and serum alanine aminotransferase (ALT) and ferritin were measured before and after intervention. RESULTS: In NAFLD, the mean VFA of 134.5 cm(2) was significantly reduced to 125.3 cm(2) after 6 months (P < 0.001). ALT levels improved significantly between the values measured before and after intervention (P = 0.039). The VFA prior to intervention was 100 cm(2) in hepatitis C patients and it was reduced significantly after 6 months to 95.6 cm(2) (P < 0.001). ALT levels also improved significantly in the hepatitis C patients (P < 0.001). The serum ferritin levels also reduced in these patients. Improvements in serum ALT and ferritin levels correlated with the amount of visceral fat reduction in both groups (P = 0.046, P = 0.008, respectively). CONCLUSION: These findings demonstrate that restriction of calorie and iron intake results in reduction of visceral fat, liver enzymes and ferritin in patients with chronic liver disease. Visceral fat may be a central target for future interventions, not only in NAFLD but also in hepatitis C.
