H. pylori pathogenesis in patients with hepatitis B virus (HBV) and related diseases remains obscure. We used ^13C-UBT to detect H. p.vlori infection in patients with chronic HBV infection, HBV-related cirrhosis, HBV-related hepatic carcinoma, and other chronic hepatic diseases. Methods: A total of 131 patients with chronic hepatitis B (HB), 179 with HBV-related cirrhosis, 103 with HBV-related hepatic carcinoma, 45 with HBV-negative hepatic carcinoma, and 150 controls were tested for H. pylori infection using ^13C-UBT. We compared H. pylori infection rate, liver function, complications of chronic hepatic disease, serum HBV-DNA, serum alpha-fetoprotein (AFP), and portal hypertensive gastropathy (PHG) incidence among groups. Results: HBV-related cirrhosis was associated with the highest H. pylori infection rate (79.3%). H. pylori infection rate in chronic HB was significantly higher than in the HBV-negative hepatic carcinoma and control groups (P 〈 0.001 ). 11. pylori infection rate in patients with HBV-DNA ≥10^3 copies/ml was significantly higher than in those with HBV-DNA 〈103 copies/ml (76.8% vs. 52.4%, P 〈 0.001). Prothrombin time (21.3 ± 3.5 s vs. 18.8 ±4.3 s), total bilirubin (47.3±12.3 μmol/L vs. 26.6±7.9 μmol/L), aspartate aminotransferase ( 184.5 ±37.6 U/L vs. 98.4 ± 23.5 U/L), blood ammonia (93.4 ± 43.6 μmol/L vs. 35.5 ± 11.7 μmol/L), and AFP (203.4±62.6 μg/L vs. 113.2± 45.8 μg/L) in the ^13C-UBT-positive group were significantly higher than in the ^13C-UBT-negative group (P 〈 0.01). The incidence rates of esophageal fundus variceal bleeding (25.4% vs. 16.0%), ascites (28.9% vs. 17.8%), and hepatic encephalopathy (24.8% vs. 13.4%) in the ^13C-UBT-positive group were significantly higher than in the 13C-UBT-negative group (P 〈 0.01 ). The percentages of patients with liver function in Child-Pugh Grade C (29.6% vs. 8.1%) and PHG (43.0% vs. 24.3%) in the ^13C-UBT-positive group were significantly higher than in the ^13C-UBT-negative group (P 〈 0.05). Conclusions: It is possible that H. pylori infection could increase liver damage caused by HBV. 1t. pylori eradication should be performed in patients with complicating H. pylori infection to delay hepatic disease progression.展开更多
