Insulin-like Growth Factor-1 Levels Reflect Muscle and Bone Health and Determine Complications and Mortality in Decompensated Cirrhosis.

Background: The growth hormone-insulin-like growth factor (GH-IGF-1) axis and its impairment with sarcopenia, frailty, bone health, complications, and prognosis are not well characterized in cirrhosis.
Methods: We investigated the adult decompensated cirrhosis out-patients at a tertiary care institute between 2021 and 2023 for serum GH and IGF-1 levels, and associated them with sarcopenia (CT-SMI in cm ² /m ² ), liver frailty index (LFI), osteodystrophy (DEXA), clinical decompensations (overall, ascites, encephalopathy, infection, and bleed), and survival up to 180 days.
Results: One-hundred-seventy-two patients, 95% males, aged 46.5 years (median). _log IGF-1 levels were negatively associated with sarcopenia, osteodystrophy, LFI, CTP, and MELD-Na score ( P  < 0.05 each). Patients with low IGF-1 levels had a higher incidence of complications (overall, ascites and encephalopathy) than those with intermediate, and high IGF-1 levels ( P  < 0.05 each). Both _log IGF-1 (AUC: 0.686) and MELD (AUC: 0.690) could predict 180-day mortality ( P  < 0.05, each). Adding _log IGF-1 with MELDNa further improved discriminative accuracy of MELDNa (AUC: 0.729) P  < 0.001. The increase in IGF-1 on follow-up was associated with better survival and fewer complications.
Conclusion: Reduced IGF-1 levels reflect sarcopenia, frailty, and osteodystrophy in cirrhosis. Low IGF-1 are associated with severity, development of decompensations, and mortality.
