Characteristics of an Outpatient Cohort with HBeAg-Negative Chronic Hepatitis B

Introduction: Patients with hepatitis Be antigen negative chronic hepatitis B (HBeAg-negative CHB) and patients inactive carriers (IC) have similar laboratory and serologic characteristics and are not always easy to distinguish. Aim: To characterize hepatitis Be antigen (HBeAg) negative chronic hepatitis B cohort based on their laboratory and virology evaluations at one point of time. Material and Methods:  A prospective non-randomized study was conducted on 109 patients with HBeAg negative chronic hepatitis B treated as outpatients at the Clinic for infectious disease and febrile conditions.   All patients underwent laboratory and serology testing, quantification of HBV DNA and HBs antigen (qHBsAg). Results: 56 patients were inactive carriers (IC) and 53 patients had HBeAg-negative CHB (AH). The mean values of ALT, HBV DNA and qHBsAg in IC were 29,13 U/L; 727,95 IU/ml and 2753,73 IU/ml respectively. In the AH group the mean values of ALT, HBV DNA and quantitative HBsAg were 50,45 U/L; 7237363,98 IU/ml and 12556,06 IU/ml respectively. The serum value of ALT was more influenced by qHBsAg than HBV DNA in both IC and AH groups (R=0.22 vs R=0.15) (p>0.05). Conclusion:  patients with inactive and active HBeAg-negative CHB have similar laboratory and serology profile. It is necessary to combine analysis of ALT, HBV DNA and qHBsAg for better discrimination between patients IC and patient swith HBeAg- negative CHB.

AIM: To characterise hepatitis Be antigen (HBeAg) negative chronic hepatitis B cohort based on their laboratory and virology evaluations at one point of time. METHODS: A prospective non-randomized study was conducted on 109 patients with HBeAg negative chronic hepatitis B treated as outpatients at the Clinic for Infectious Diseases and Febrile Conditions. All patients underwent laboratory and serology testing, quantification of HBV DNA and HBs antigen (qHBsAg). RESULTS: A group of 56 patients were inactive carriers (IC), and 53 patients had HBeAg-negative CHB (AH). The mean values of ALT, HBV DNA and qHBsAg in IC were 29.13 U/L; 727.95 IU/ml and 2753.73 IU/ml respectively.

CONCLUSION: patients with inactive and active HBeAg-negative CHB have similar laboratory and serology profile. It is necessary to combine analysis of ALT, HBV DNA and qHBsAg for better discrimination between patient's IC and patient with HBeAg-negative CHB.
