Introduction Nationwide studies comparing patients with hepatitis B and C virus (HBV and HCV) infections are mandatory for assessing changes in epidemiology. Aim The aim of this study was to compare epidemiological data and initial management of newly diagnosed patients with persistent HBV (HBsAg positive) or HCV (detectable HCV RNA) infection in Belgium. Patients and methods Data were extracted from two Belgian observational databases. Results A total of 655 patients (387 HBV and 268 HCV) were included. Compared with HCV patients, HBV patients were younger, more frequently men, more often of Asian or African origin (43 vs. 10%, P < 0.0001), and less frequently contaminated by transfusion or intravenous drug use (9 and 6% vs. 34 and 44%, P< 0.0001). Viral replication was assessed in 89% of HBV patients. Compared with HCV patients, HBV patients more frequently had normal alanine aminotransferase (ALT) levels (65 vs. 29%, P < 0.0001), less frequently underwent liver biopsy (29 vs. 67%, P < 0.0001), and were less often considered for antiviral therapy (25 vs. 54%, P < 0.0001). When taking only HBV patients with detectable viral replication into consideration, results remained unchanged. During the multivariate analysis, ALT was a major factor for performing liver biopsy or considering antiviral therapy in both groups. Conclusion HBV and HCV screening policies should be targeted toward immigrants and intravenous drug users, respectively. Guidelines recommending systematic search for viral replication should be reinforced in HBV patients. HBV patients less frequently underwent liver biopsy and were less often considered for antiviral therapy compared with HCV patients. Despite the lack of sensitivity and specificity, ALT remains a pivotal decision-making tool for liver biopsy and antiviral therapy in both infections. [less ▲]Detailed reference viewed: 18 (0 ULg)

Introduction : Nationwide studies are mandatory to assess changes in the epidemiology of HBV infection in Europe. Aim : To describe epidemiological characteristics of HBsAgpositive patients, especially inactive carriers, and to evaluate how practitioners manage HBV patients in real life. Methods : Belgian physicians were asked to report all chronically infected HBV patients during a one-year period. Results : Among 1,456 patients included, 1,035 (71%) were classified into one of four phases of chronic infection : immune tolerance (n = 10), HBeAg-positive hepatitis (n = 248), HBeAgnegative hepatitis (n = 420) and inactive carrier state (n = 357 HBeAg-negative patients with ALT < upper limit of normal (ULN) and HBV DNA < 2,000 IU/mL). Using less restrictive criteria for ALT (1-2 ULN) or HBV DNA (2,000-20,000 IU/mL), 93 unclassified patients were added to the group of inactive carriers. These 93 additional inactive carriers were younger, more frequently males, with similar risk factors for HBV infection and histological features compared to inactive carriers according to recent guidelines. Recent guidelines on management of HBV patients were generally followed, but systematic HBV DNA measurements and HDV coinfection screening should be reinforced. Conclusion : In Belgium, an inactive carrier state was a common form of chronic HBV infection. Using less restrictive criteria for classification of inactive carriers did not modify their main characteristics and seemed better adapted to clinical practice. Recent guidelines on management of HBV patients should be reinforced. [less ▲]Detailed reference viewed: 22 (3 ULg)
