Background: Sleep disturbance and decreased health-related quality of life (HRQOL) are significant complaints in patients with liver cirrhosis. Although the etiology of these complications is unclear, we propose that glucose intolerance may be a predisposing factor. Therefore, our aim was to investigate the relationship between glucose intolerance and these complications. Methods: We assessed continuous glucose monitoring in 43 patients with chronic liver disease. Among these patients, 36 completed the Pittsburgh Sleep Quality Index (PSQI), the 36-Item Short-form Health Survey (SF-36), and the Neuropsychological Test (NPT). We also assessed the change in glucose fluctuations between preoperative periods and 1 year after liver transplantation in 13 patients. Results: Standard deviation (SD) of blood glucose was 24.15 ± 13.52. SD values correlated to glucose metabolism measures, including HbA1c and glycoalbumin. SD values also correlated to markers of liver fibrosis, including type IV collagen. Twenty-one patients (58.3 %) were classified as “poor” sleepers, with a global PSQI score ≥6. Glucose fluctuations correlated with the global PSQI score (r = 0.456, p = 0.008) and the SF-36 score (r = 0.434, p = 0.013). Multivariate regression analysis identified SD values as an independent risk factor for sleep disturbance (r = 0.12, p = 0.039) and decreased HRQOL (r = −0.32, p = 0.024). SD values did not correlate with the NPT. SD values were also improved in 11 (84.6 %) patients 1 year after liver transplantation. Conclusion: Abnormal glucose fluctuations are a risk factor for sleep disturbance and decrease of HRQOL in patients with cirrhosis.
