Seroconversion of HBsAg in HBeAg positive and HBeAg negative patients with chronic HBV treated with entecavir: a case series.

We report a case series of three HBeAg positive and five HBeAg negative patients (7 males, mean age 50.6 +/- 14.6 years) with chronic HBV infection experiencing seroconversion after treatment with entecavir (0.

A possible misdiagnosis in patients presenting with acute HBsAg-negative hepatitis: the role of hepatitis delta virus.

We describe here two cases of delta hepatitis (a coinfection and a superinfection) presenting as acute HBsAg-negative hepatitis. The first patient, a parenteral drug abuser, had a biphasic course of the disease, with HBsAg detectable transiently only during the relapse. Testing for delta markers on stored sera gave evidence of HBV/HDV coinfection.
