Liver disease resulting from heart disease has generally been referred as "cardiac hepatopathy." The two main forms of cardiac hepatopathy are acute cardiogenic liver injury (ACLI) and congestive hepatopathy (CH). ACLI most commonly occurs in the setting of acute cardiocirculatory failure, whereas CH results from passive venous congestion in the setting of chronic right-sided heart failure (HF). Both conditions often coexist and potentiate the deleterious effects of each other on the liver. In CH, the chronic passive congestion leads to sinusoidal hypertension, centrilobular fibrosis, and ultimately, cirrhosis ("cardiac cirrhosis") and hepatocellular carcinoma. The differentiation between congestion and fibrosis currently represents an unmet need and a growing research area. Although cardiac cirrhosis may only arise after several decades of ongoing injury, the long-term survival of cardiac patients due to advances in medical and surgical treatments is responsible for the increased number of liver complications in this setting. Eventually, the liver disease could become as clinically relevant as the cardiac disease and further complicate its management.
Summary
Background and Aims
To assess whether corticosteroids improve prognosis in patients with AS‐AIH, and to identify factors at therapy initiation and during therapy predictive of the response to corticosteroids.
Methods
This was a retrospective cohort study including all patients with AS‐AIH admitted to 13 tertiary centres from January 2002 to January 2019. The composite primary outcome was death or liver transplantation within 90 days of admission. Kaplan–Meier and Cox regression methods were used for data analysis.
Results
Of 242 consecutive patients enrolled (mean age [SD] 49.7 [16.8] years), 203 received corticosteroids. Overall 90‐day transplant‐free survival was 61.6% (95% confidence interval [CI] 55.4–67.7). Corticosteroids reduced the risk of a poor outcome (adjusted hazard ratio [HR] 0.25; 95% CI 0.2–0.4), but this treatment failed in 30.5%. An internally validated nomogram composed of older age, MELD, encephalopathy and ascites at the initiation of corticosteroids accurately predicted the response (C‐index 0.82; [95% CI 0.8–0.9]). In responders, MELD significantly improved from days 3 to 14 but remained unchanged in non‐responders. MELD on day 7 with a cut‐off of 25 (sensitivity 62.5%[95% CI: 47.0–75.8]; specificity 95.2% [95% CI: 89.9–97.8]) was the best univariate predictor of the response. Prolonging corticosteroids did not increase the overall infection risk (adjusted HR 0.75; 95% CI 0.3–2.1).
Conclusion
Older patients with high MELD, encephalopathy or ascites at steroid therapy initiation and during treatment are unlikely to show a favourable response and so prolonged therapy in these patients, especially if they are transplantation candidates, should be avoided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
