Abstract

BACKGROUND: Metformin may protect against hepatocellular carcinoma and mortality among patients with type 2 diabetes. AIM: To investigate whether long-term use of metformin improves survival and reduces liver-related outcomes among patients with type 2 diabetes and non-alcoholic steatohepatitis. METHODS: A total of 191 diabetic patients with biopsy-proven non-alcoholic steatohepatitis and bridging fibrosis or compensated cirrhosis were retrospectively identified at Indiana University Medical Center between October 2004 and January 2016. Of them, 110 were users and 81 never-users of metformin. Primary outcomes were transplant-free survival, development of hepatocellular carcinoma or a first event of hepatic decompensation. RESULTS: Cirrhosis was present in 85% of metformin users and 88% of nonusers. Metformin dose was greater than or equal to 1 g/d in 104 out of 110 users and its median duration of use was 6 (95% CI: 4.4-7.9) years. The mean follow-up was 6.92 and 6.80 years for metformin users and non-users, respectively. During follow-up, 28 patients developed hepatocellular carcinoma (metformin users: 7, nonusers: 21), and 52 died (metformin users: 7, nonusers: 24) or were transplanted (metformin users: 13, non-users: 13). Metformin use was associated with lower risk of overall mortality or transplant (HR: 0.42; 95% CI: 0.24-0.74, P = 0.003) and hepatocellular carcinoma (sHR: 0.25; 95% CI: 0.11-0.58, P = 0.001), and remained independently associated with both outcomes after propensity-score and covariate-adjusted analyses. No instances of hepatotoxicity or lactic acidosis were observed. CONCLUSION: Our study demonstrated an association between long-term metformin use and reduced the risk of all-cause mortality/transplant and hepatocellular carcinoma in diabetics with non-alcoholic steatohepatitis and advanced fibrosis.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Observational and case-control studies indicate that, in people with T2D and MASLD-related advanced fibrosis or cirrhosis, metformin may improve transplant-free survival (but not the risk of hepatic decompensation), and reduce the risk of primary liver and extrahepatic cancer.

    “As far as clinical outcomes, there is some indication from observational and case-control studies that, in people with T2D and MASLD-related advanced fi brosis or cirrhosis, metformin may improve transplant-free survival (but not the risk of hepatic decompensation), and reduce the risk of primary liver and extrahepatic cancer.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
