BACKGROUND AND AIMS: HDV infection is the most severe form of chronic hepatitis. However, studies on outcomes and causes of death in a US-born population, with primarily horizontal transmission of HDV, are lacking. The aim of this study was to conduct a national study of patients with hepatitis D to understand the natural history and outcomes compared to patients with HBV infection.
APPROACH AND RESULTS: In a national cohort of 4817 veterans infected with HBV tested for HDV (99.6% US-born, 3.3% HDV-positive) over a 23-year period, we used multivariable models to identify the factors associated with a composite outcome of HCC, decompensation, and liver-related mortality, and all-cause mortality of patients with HDV compared to HBV mono-infection. HDV coinfection (vs. HBV mono-infection) was associated with a significantly higher incidence of composite liver-related outcomes at both 5 (23.84 vs. 7.98, p < 0.001) and 10 years (19.14 vs. 10.18, p < 0.001), respectively. The most common cause of death was liver-related (33.8% for HDV vs. 24.7% for HBV), followed by nonhepatic malignancies (15.6% vs. 14.8%), cardiac (11.7% vs. 15.2%), and lung disease (5.2% vs. 3.7%). In multivariable models, HDV was associated with an increased risk of composite liver outcomes (adjusted hazard ratio: 2.57, 95% CI: 1.87-3.52, p < 0.001) and all-cause mortality (adjusted hazard ratio: 1.52, 95% CI: 1.20-1.93, p < 0.001).
CONCLUSIONS: In a predominantly US-born cohort of veterans, HDV coinfection was associated with an increased risk of liver-related outcomes and all-cause mortality. Our findings support widespread testing for early identification of HDV.
