2. Serious complications: including heart failure (≥ New York Heart Association (NYHA) class III), renal insufficiency (creatinine clearance ≤ 30 ml/min), liver dysfunction (serum Alanine transaminase (ALT) or aspartate aminotransferase (AST) greater than three times the upper limit of normal, or total bilirubin greater than Normal upper limit.
