Sustained virologic response after eight weeks of treatment with sofosbuvir, ledipasvir, and ribavirin in a decompensated cirrhotic patient with hepatitis C virus genotype 1b

A 68‐year‐old Japanese man with decompensated cirrhosis due to hepatitis C virus (HCV) genotype 1b infection was treated with sofosbuvir (SOF; 400 mg/day), ledipasvir (LDV; 90 mg/day), and ribavirin (RBV; 400 mg/day). Before treatment, his Child–Pugh and Model for End‐Stage Liver Disease (MELD) scores were 10 (class C) and 13 points, respectively. Although RBV was initially given at two‐thirds the normal dose due to anemia, his hemoglobin level gradually declined, and RBV was reduced to 200 mg daily on day 11, and 200 mg every other day on day 14. His alanine aminotransferase level gradually decreased during combination therapy; and HCV‐RNA was undetectable on day 28. He complained of fatigue from day 49, and RBV was ceased. On day 56, he asked to discontinue treatment because of strong fatigue and insomnia. As hepatic encephalopathy occurred just after the cessation of direct‐acting antivirals, diuretics were discontinued, and treatment with synthetic disaccharides and intractable antibiotics were given, after which his consciousness returned to normal. Ascites gradually disappeared, and a sustained virologic response (SVR) was achieved. At 1.5 years after treatment, his Child–Pugh and MELD scores had improved to 6 (class A) and 10 points, respectively. Although he did not experience hepatic encephalopathy during the observation period, his blood ammonia concentration persistently increased. We reported a case of decompensated cirrhosis in a patient who achieved SVR with SOF/LDV plus RBV for 8 weeks. Although his liver function improved after treatment, careful long‐term observation is required for complications of liver cirrhosis, even after HCV elimination.
