The objective was to explore the characteristics of energy metabolism in patients with alcoholic liver cirrhosis (ALC) and diabetes mellitus (DM).
Thirty-four male patients with ALC and DM, 30 male patients with ALC without DM and 10 male healthy controls (HC) were enrolled in this study. Resting energy expenditure (REE), respiratory quotient (RQ) were measured by indirect calorimetry. Data were analyzed using the Student's t-test, Mann-Whitney U-test and χ2 tests between two groups. Logistic regression analysis was used to analyze the risk factors for hypermetabolism.
Measured REE was significantly higher in patients with ALC and DM (1740 ± 338 kcal/d) than in patients with ALC (1400 ± 304 kcal/d, P < 0.01). Fasting blood glucose was an independent factor predicting hypermetabolism in all of the patients with ALC (P = 0.005). RQ was lower in patients with ALC and DM (0.80 ± 0.06) than in patients with ALC (0.83 ± 0.05, P = 0.027) and the HC (0.86 ± 0.03, P = 0.001). In the ALC and DM group, measured REE as percentage of predicted REE by Harris-Benedict formula was higher in patients with HbA1c ≥ 7.5% than in those with HbA1c < 7.5% (126.36 ± 15.19% vs. 109.48 ± 23.89%, P = 0.040).
REE was increased and RQ was significantly decreased in patients with ALC and DM. These changes were associated with poor glucose control. HbA1c less than 7.5% may reduce the risk of hypermetabolism.
