The natural history of compensated HCV-related cirrhosis: a prospective long-term study

Abstract

Background & aims: The natural history of HCV-related compensated cirrhosis has been poorly investigated in Latin-American countries. Our study evaluated mortality and clinical outcomes in compensated cirrhotic patients followed for 6 years.

Methods: Four hundred and two patients with compensated HCV-related cirrhosis were prospectively recruited in a tertiary care academic center. At the time of admission, patients were stratified as compensated (absence [stage 1] or presence [stage 2] of esophageal varices) as defined by D'Amico et al. Subjects were followed to identify overall mortality or liver transplantation and clinical complication rates.

Results: Among 402 subjects, 294 were categorized as stage 1 and 108 as stage 2. Over a median of 176 weeks, 42 deaths occurred (10%), of which 30 were considered liver-related (7%) and 12 non-liver-related (3%); eight individuals (2%) underwent liver transplantation; 30 patients (7%) developed HCC, 67 individuals in stage 1 (22%) developed varices and any event of clinical decompensation occurred in 80 patients (20%). The 6-year cumulative overall mortality or liver transplantation was 15% and 45%, for stages 1 and 2, respectively (p<0.001). The cumulative 6-year HCC incidence was significantly higher among patients with varices (29%) than those without varices (9%), p<0.001. Similarly, the cumulative 6-year incidence of any clinical liver-related complication was higher in patients with stage 2 (66%) as compared to 26% in those with stage 1, respectively (p<0.001).

Conclusions: Our results indicate significant morbidity and mortality and clinical outcome rates in compensated cirrhotic patients with varices (stage 2).
