“…In HBeAg(-) chronic hepatitis B, ALT levels can flare with an intervening period of normal values, can continue to increase without flare, or demonstrate intermittent flares superimposed on a continuous elevation [17,18] . The majority of our patients belonged to the first profile.…”
AIM:To determine whether new cut-off values for alanine aminotransferase (ALT) and baseline hepatitis B virus (HBV) DNA levels better differentiate HBeAg(-) chronic hepatitis B (CHB) patients from inactive chronic carriers.
METHODS:Ninety-one patients [32 HBeAg(+) CHB, 19 inactive carriers and 40 HBeAg(-) CHB] were followed up for 2 years and were tested for HBV DNA levels by a PCR-based assay. ALT was tested twice during the last 6 mo using new cut-off values: ULN (upper limit of normal) 30 IU/L for males, 19 IU/L for females. Diagnostic accuracy, sensitivity, specificity, positive and negative predictive values were calculated by discriminant analysis.
RESULTS:When using the revised ALT cut-off values, the lowest optimal HBV DNA level that differentiated HBeAg(-) CHB patients from inactive carriers was 50 000 copies/mL. The diagnostic accuracy of HBV DNA to determine inactive carriers with a cut-off of 50 000 copies/mL was similar to the previously recommended cut-off of 100 000 copies/mL (91%). HBV DNA levels were lower than the cut-off value in 95% of inactive carriers and in 28% of HBeAg(-) CHB patients. With ALT < 30 IU/L in men and < 19 IU/L in women and HBV DNA levels < 100 000 copies/mL, the risk of CHB is 5%. On the other hand, if ALT values were > 30 IU in men and > 19 IU in women and baseline HBV DNA levels were > 100 000 copies/mL, the risk is 86%.
CONCLUSION:
“…In HBeAg(-) chronic hepatitis B, ALT levels can flare with an intervening period of normal values, can continue to increase without flare, or demonstrate intermittent flares superimposed on a continuous elevation [17,18] . The majority of our patients belonged to the first profile.…”

CONCLUSION:
“…Preventive nucleoside analog against HBV is currently recommended for 4-6 mo after chemotherapy completion [46,50,52,61] . However, reports of HBV reactivation 4 to 6 mo after chemotherapy [62][63][64][65] suggest that this number should be revised. The current 6 mo value probably reflects our knowledge about the changes in B-cell numbers [60,64,[66][67][68] .…”

“…Telbivudine may also be used in the prophylaxis of HBV reactivation. Compared to lamivudine and telbivudine, entecavir is less likely to induce drug resistance in HBV, which has a treatment advantage and the preventive administration of HBV reactivation [65] . For this reason, entecavir administration is recommended for cases in which preventive administration against HBV will last 12 mo or more [50,52] .…”

“…An estimated 400 million people worldwide have chronic hepatitis B virus (HBV) infection, and more than 500 000 people die every year from complications of HBVrelated chronic liver disease [1] . In patients chronically infected with HBV, acute exacerbations are clinically important because they can have severe or even fatal consequences [2] .…”
Of patients with severe exacerbation of chronic hepatitis B accompanied by jaundice and coagulopathy, 20%-30% have a fatal outcome. In this report, we describe 2 cases of severe exacerbation of chronic hepatitis B with jaundice and coagulopathy who were successfully treated with a combination of entecavir and corticosteroid. In both cases, rapid reductions in serum hepatitis B virus (HBV)-DNA levels were observed, and corticosteroid was stopped after serum HBV-DNA levels became undetectable. Entecavir treatment was continued. Generally, entecavir treatment reduced serum HBV-DNA levels rapidly, although the improvement in liver function was delayed by a few weeks. During this time lag, liver cell injury continued and the disease progressed. Corticosteroid suppressed the excessive host immune response and was useful for stopping progressive deterioration. A combination of entecavir and early-phase corticosteroid may be a useful treatment in severe exacerbation of chronic hepatitis B.
