Severe alpha-1 antitrypsin deficiency is associated with a higher risk of complications after first decompensation than other aetiologies of cirrhosis

Original language description

Background &amp; Aims: Alpha-1 antitrypsin deficiency (AATD) causes/predisposes to advanced chronic liver disease. However, the role of the SERPINA1 Pi &amp; lowast;ZZ genotype in patients with decompensated cirrhosis is unclear. Thus, we evaluated the impact of the Pi &amp; lowast;ZZ genotype on the disease course after the first hepatic decompensation event. Methods: We retrospectively included 59 adults with decompensated cirrhosis and severe AATD (Pi &amp; lowast;ZZ) from 12 European tertiary care centres. First decompensation was considered as baseline. To compare the course of AATD to other cirrhosis aetiologies, we applied propensity score matching for Child-Turcotte-Pugh (CTP) score as well as age/sex. Patients were followed until further decompensation, liver transplantation or liver-related death. Results: Most patients were male (74.6%), with a mean age of 55 years. The most common type of first decompensation was ascites (n = 40; 67.8%), followed by variceal bleeding (n = 13; 22.0%) and overt hepatic encephalopathy (n = 6; 10.2%). Median CTP and MELD (model for end-stage liver disease) scores at first decompensation were 8 and 14, respectively. Median MELD scores were 16 and 20 points at listing and liver transplantation (median time on list: 2.9 [IQR 1.1-7.2] months), respectively. Patients with other aetiologies (subdistribution hazard ratio: steatotic liver disease: 0.62, 95% CI 0.44-0.88, p = 0.007; abstinent alcohol-associated liver disease: 0.50, 95% CI 0.35-0.71, p &lt;0.001; hepatitis C virus-associated cirrhosis: 0.56, 95% CI 0.37-0.83, p = 0.004) had a significantly lower risk of further hepatic decompensation, liver transplantation, or liver-related death, compared to those with Pi &amp; lowast;ZZ. Exchanging further decompensation with acute-on-chronic liver failure yielded similar results. Conclusion: Our study defines the course of decompensated cirrhosis in patients with severe AATD (Pi &amp; lowast;ZZ), who are particularly prone to complications of cirrhosis and exhibit a more progressive disease course than those with cirrhosis of other aetiologies.
