title: Antiviral therapy reduces portal pressure in patients with cirrhosis due to HBeAg-negative chronic hepatitis B and significant portal hypertension.
abstract: OBJECTIVE
  Lamivudine improves liver histology in patients with chronic hepatitis B (CHB), but its effects on portal pressure remain unknown. We evaluated the effect of lamivudine monotherapy on hepatic venous pressure gradient (HVPG) in CHB-related cirrhosis with significant portal hypertension.
  
  
  METHODS
  We studied 19 patients with cirrhosis due to HBeAg-negative CHB and HVPG >or=10 mm Hg treated with oral lamivudine (100mg daily). Liver biochemistry, Child-Pugh and MELD score were determined every 3 months, alpha-fetoprotein and HBV DNA every 6 months and HVPG at baseline and at 12 months after lamivudine initiation. Diuretics, beta-blockers, antibiotics and/or endoscopic therapy were used for routine indications.
  
  
  RESULTS
  At 12 months, a significant reduction was observed in ALT (p=0.001), HBV DNA (p=0.002), Child-Pugh (p=0.012) and MELD score (p=0.006). Four patients developed virological breakthrough during treatment. At 12 months, HVPG decreased in all but one patient [baseline: 14.4+/-3.9 and 12 months: 12.4+/-3.3 mm Hg (p=0.007)]. HVPG decreased >20% or below the 12 mm Hg threshold in 10 of 13 patients with baseline HVPG >or=12 mm Hg. HVPG increased in a patient with hepatic flare after virological breakthrough.
  
  
  CONCLUSIONS
  In conclusion, in patients with cirrhosis due to HBeAg-negative CHB, lamivudine monotherapy reduces HVPG, especially when virological suppression and biochemical remission is achieved.
