Increased Mortality Among Persons With Chronic Hepatitis C With Moderate or Severe Liver Disease: A Cohort Study.
Ontology highlight
ABSTRACT: Background
Despite the availability of curative treatment for hepatitis C virus (HCV) infection, because of cost, treatment is often denied until liver fibrosis has progressed to at least moderate fibrosis and, in some cases, cirrhosis. That practice is justified on assumptions that there are no medical consequences to having moderate disease and that disease stage transitions can be anticipated.Methods
We performed transient elastography on 964 people chronically infected with HCV with a history of injection drug use living in Baltimore, Maryland. Liver stiffness was evaluated semiannually from 2006 to 2014 using validated cutoffs for moderate fibrosis (8.0-12.3 kPa) and severe fibrosis/cirrhosis (>12.3 kPa).Results
Among 964 persons, 62%, 23% and 15% had baseline measurements suggestive of no/mild fibrosis, moderate fibrosis, and severe fibrosis/cirrhosis, respectively. All-cause and nonaccidental mortality were elevated in persons with moderate fibrosis (adjusted hazard ratio [aHR], 1.42 [95% confidence interval {CI}, .96-2.11]; aHR, 1.66 [95% CI, 1.06-2.59], respectively) after adjustment for sociodemographics, substance use, and human immunodeficiency virus status. Despite the increased risk of mortality among those with moderate fibrosis, no combination of demographic, behavioral, and clinical factors, nor changes in stiffness measurements themselves could predict the transition from mild to moderate fibrosis with sufficiently high diagnostic accuracy (C-statistic = 0.72 for best-performing model).Conclusions
Delaying treatment for anyone chronically infected with HCV regardless of fibrosis stage may be detrimental given the increased risk of mortality even for those with moderate disease and the inability to predict the transition from mild to moderate disease.
