Abstract Background Insulin resistance (IR) is frequently associated with chronic liver disease. There has been an increased interest in betatrophin protein and its involvement in the compensatory response to IR. We aimed to investigate the correlation of serum betatrophin levels with disease severity and the emergence of IR in cirrhotic patients. This study included 27 cirrhotic patients and 30 healthy participants who served as a control group. IR was assessed by the Homeostasis Model Assessment (HOMA-IR). Serum insulin and betatrophin levels were measured using Enzyme-Linked Immunosorbent Assay (ELISA). Results IR was existing in 74% of cirrhotic patients (p < 0.001). Subjects with IR had higher serum betatrophin levels than those without IR (p = 0.04). Serum betatrophin levels were significantly higher in cirrhotic patients than controls (p < 0.001). In addition, Child-Pugh class C patients had higher serum betatrophin levels than those with Child-Pugh class B cirrhosis (p = 0.01). Moreover, the highest serum betatrophin levels were detected in patients with tense ascites followed by those with moderate and mild ascites (p = 0.01). In the cirrhosis group, serum betatrophin levels correlated positively with fasting blood glucose levels (p < 0.001), fasting insulin levels (p = 0.006), HOMA-IR (p = 0.006), Child-Pugh score (p = 0.023), MELD score (p < 0.001), and INR (p = 0.005), and correlated negatively with platelets count (p = 0.01). Conclusion Cirrhotic patients have higher serum betatrophin levels; moreover, these levels are positively correlated with disease severity as well as the emergence of insulin resistance.
