Article: Virologic response is not durable after adefovir discontinuation in lamivudine-resistant chronic hepatitis B patients.
[show abstract] [hide abstract]
ABSTRACT: We investigated the durability of the biochemical and virologic responses after adefovir (ADV) discontinuation in lamivudine-resistant (LMV-R) chronic hepatitis B (CHB) patients, and the outcomes of ADV discontinuation compared to that of ADV maintenance. The indication for ADV treatment cessation was an undetectable level of hepatitis B virus (HBV) DNA documented on two occasions at least 6 months apart. All patients received additional ADV for at least 12 months after the confirmation of undetectable HBV DNA (Cobas TaqMan PCR assay, <70 copies/mL). Of 36 patients who had a sufficient ADV therapeutic effect, 19 discontinued ADV treatment, while the others maintained it. A virologic rebound was arbitrarily defined as the redetection of HBV DNA at a level higher than 10(5) copies/mL. In the ADV discontinuation group, ADV treatment and additional therapy were administered for medians of 33 months (range, 12-47 months) and 18 months, respectively. The patients were followed for a median of 12 months (range, 3-30 months) after ADV cessation. During that period, 18 of 19 patients (95%) experienced viral relapse. Viral rebound was observed in six patients (32%). However, 12 of 18 patients (67%) exhibited serum HBV DNA levels of less than (5) copies/mL. Biochemical relapses were observed in four of the six patients with viral rebound. In the ADV maintenance group, patients were treated for a median of 53 months (range, 31-85 months), and 9 patients (53%) experienced viral breakthrough. During short-term follow-up after ADV discontinuation, most patients (95%) exhibited viral relapse, whereas and viral breakthrough occurred in about half of patients (53%) maintained on ADV therapy. Therefore, the durability of virologic response after ADV discontinuation in LMV-R patients was unsatisfactory. In addition, and viral breakthrough was not infrequent in the ADV continuation group.The Korean journal of hepatology. 12/2011; 17(4):261-7. -
Article: Carotid intima-media thickness is increased not only in non-alcoholic fatty liver disease patients but also in alcoholic fatty liver patients.

ABSTRACT: There are many reports of non-alcoholic fatty liver disease (NAFLD) patients with increased carotid intima-media thickness (IMT). However, there is little information about carotid IMT in alcoholic fatty liver disease (AFLD) patients. We aimed to compare the carotid IMT of NAFLD patients and AFLD patients. The medical records of individuals who underwent carotid IMT measurement and abdominal ultrasonography between January 2006 and December 2008 at Korea University Ansan Hospital were retrospectively reviewed. The patients were divided into group A (no fatty liver without alcohol history), group B (NAFLD), group C (AFLD) and group D (no fatty liver with alcohol history). The carotid IMT results were compared across all groups. The mean carotid IMT was 0.55 ± 0.1 mm for group A, 0.6 ± 0.1 mm for group B, 0.59 ± 0.1 mm for group C, and 0.54 ± 0.1 mm for group D. There were significant differences between groups A and B, groups A and C, and groups C and D (p < 0.05), but there were no differences between groups B and C (p = 0.736). We determined that patients with fatty livers have an increased carotid IMT both in NAFLD and AFLD patients.Digestion 04/2011; 84(2):149-55. · 2.05 Impact Factor
