[Analysis of clinical characteristics of 481 HBV-related liver cirrhotic patients with low viral load].

To analyze the clinical characteristics of HBV-related liver cirrhotic patients with low viral load. A retrospective analysis on 481 inpatients with HBV-related cirrhosis with low viral load [HBV DNA≤2 000 IU/ml (10(4) copies/ml)] general condition, virological indicators, liver function-related indicators, complications, and incidence of complications were analyzed. The t-test was used to compare the average measurement data, and the (2) test was used to compare the count data. 481 cases were mainly male (male/female: 324/157), aged 20-83 (53.31 ± 11.67) years old. Han nationality accounted for 71.518%. 386 cases were HBsAg positive. 391 cases were HBeAg positive, and 140 cases were HBV DNA positive. The average value of bilirubin, albumin, alanine aminotransferase, aspartate aminotransferase, platelets, and prothrombin were 50.59 ± 91.25 (μmol/L), 33.68 ± 7.5 (g/L), and 60.66 ± 106.95(U/L), 63.37 ± 86.19(U/L), 106.65 ± 83.22(×10(9)/L), 68.82% ± 25.33%, respectively. CTP class A/B/C had 220/150/111 cases. The average values of CTP, MELD, APRI and FIB-4 were 7.61 ± 2.58, 10.98 ± 5.79, 2.34 ± 3.56, 6.91 ± 8.04, respectively. The overall incidence of complications in HBV-related cirrhotic patients with low viral load, HBV DNA negative, HBV DNA positive, HBsAg negative, and HBsAg positive were 80.0%, 82.7%, 73.6%, 85.3%, and 78.8%, respectively. Among them, 283 cases (58.84%), 197 cases (55.77%), 86 cases (61.43%), 52 cases (54.74%) and 231 cases (59.84%) were of hypersplenism, and 267 cases (55.51%), 197 cases (55.77%), 70 cases (50.00%), 56 cases (58.95%), and 211 cases (54.66%) were of esophagogastric varices. There were 59 cases (12.27%), 48 cases (14.08%), 11 cases (7.86%), 12 cases (12.63%), and 47 cases (12.18%) of rupture of esophageal and gastric varices, respectively. 202 cases (42.00%), 147 cases (43.11%), 55 cases (39.29%), 42 cases (44.21%), and 160 cases (41.45%) were of ascites, respectively. 17 cases (3.53%), 12 cases (3.52%), 5 cases (3.5%), 2 cases (2.11%), 15 (3.89%) cases were of hepatic encephalopathy, respectively. There were 6 cases (1.25%), 3 cases (0.88%), 3 cases (2.14%), 0 cases (0%), 6 cases (1.55%) of liver cancer. 29 cases (6.03%), 21 cases (6.16%), 8 cases (5.71%), 9 cases (9.47%) and 20 cases (5.18%) were of portal vein thrombosis. Compared with the overall incidence of complications, 341 HBV DNA-negative patients and 95 HBsAg-negative patients still had higher incidence of complications. The patients were grouped by age, and in < 40 years old, 40-50 years old, and > 50 years old, the overall complications were 80.8% in 42 cases, 76.8% in 116 cases and 81.7% in 227 cases, and the difference was not statistically significant. HBV infection patients with low viral load, and those whose HBsAg has disappeared, are still at risk of developing liver cirrhosis and even serious complications, and whether such population need antiviral therapy and benefit from it deserves further research.
