The clinical efficacy and safety of adefovir dipivoxil in combination with bicyclol for the treatment of senior patients with chronic hepatitis B / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate the clinical efficacy and safety of adefovir dipivoxil (ADV) in combination with bicyclol for the treatment of chronic hepatitis B (CHB) in seniors.</p><p><b>METHODS</b>96 senior patients with CHB were randomly divided into two groups, the treatment group and the control group. On the basis of routine liver protective treatment, patients in the treatment group received ADV (10 mg/d) and bicyclol tablets (25 mg, tid.) orally, and those in the control group were orally administrated ADV tablets (10 mg/d) only. The treatment course for both groups was 24 weeks. Serum ALT, AST, and alterations of virological parameters were observed before and after the treatment.</p><p><b>RESULTS</b>Before and at the end of the 24 weeks treatment, ALT level for the treatment group was (208.44 +/- 94.22) and (34.47 +/- 12.79) U/L, and those for the control group was (205.73 +/- 96.48) and (44.20 +/- 21.96) U/L, respectively (difference between groups P < 0.01). At the end of the 24 weeks treatment, ALT normalization rates for the treatment group and the control group were 76.6% and 54.5%, respectively, and AST normalization rates for them were 76.6% and 54.5%, respectively (both differences between groups P < 0.05); HBV DNA loads for the treatment group and the control group were decreased by (3.1 +/- 1.40) lgIU/ml and (2.98 +/- 1.17) lgIU/ ml, respectively (difference between groups P > 0.05). The incidence rates of adverse events between two groups were not statistically significant.</p><p><b>CONCLUSION</b>It suggested that the treatment of ADV in combination with bicyclol for senior patients with CHB is effective and safe.</p>

An analysis of the clinical characteristics of patients with chronic hepatitis B superinfected with acute hepatitis E / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate clinical features of the patients with hepatitis B superinfected with acute hepatitis E (AHE).</p><p><b>METHODS</b>Totally 625 consecutive patients enrolled from Dec 2002 to Dec 2006 were studied retrospectively. All of the patients were subclassified into acute hepatitis E group (AHE=437 cases) and Superinfected Group (S=188 cases), and S group was further divided into the group of chronic hepatitis B superinfected with acute hepatitis E (CHB+AHE, 130 cases) and the group of liver cirrhosis and hepatitis B superinfected with acute hepatitis E (LCB+AHE, 58 cases). In 32 of the 188 superinfected patients the effects of HEV on HBV were observed by comparing the levels of HBV DNA in acute vs. convalescence stages.</p><p><b>RESULTS</b>Compared with the patients with AHE, the superinfected patients had a higher level of total bilirubin (TBil), an elevated frequency of fulminate hepatitis, mortality and a longer period of the mean hospital stay for the cured patients but significantly lower levels of alanine aminotransferase (ALT), serum albumin and prothrombin activity (PA). Furthermore, the group of LCB+AHE had a higher level of TBil and higher incidences of complications such as ascites, peritonitis, hepatic encephalopathy and disturbance in glycometabolism than the group of CHB+AHE. The follow-up for the superinfected patients showed that 20 of 32 patients (62.5 percent) had decreased copies of HBV DNA during the recovery phase compared with the acute phase, and the mean decrease of HBV DNA was 2.1 log10. The HBV DNA was in a persistently undetectable level in 6 of 32 (18.8 percent) superinfected patients. However, 4 of 32 patients (12.5 percent) showed an unchanged levels of HBV DNA and 2 cases (6.2 percent) had a slightly increased HBV DNA levels.</p><p><b>CONCLUSION</b>Superinfection with AHE in patients with chronic hepatitis B leads to a more severe hepatic damage and the replication of HBV DNA can be transiently inhibited.</p>

Clinical research on the effect of Oxymatrine on serum cholinesterase / 中华实验和临床病毒学杂志

<p><b>BACKGROUND</b>To investigate the effect of Oxymatrine (OM) on serum cholinesterase (ChE) during the treatment of viral hepatitis and the relationship between the change of ChE and the change of albumin (ALB), prothrombin activity (PTA) and other liver function tests.</p><p><b>METHODS</b>A total of 98 patients with viral hepatitis were divided into four groups. Group A consisted of 31 patients and were treated with OM intravenous infusion; Group B consisted of 30 patients, treated with OM orally; Group C consisted of 7 patients and were treated with OM intramuscular injection while Group D consisted of 30 patients, and were not treated with OM. ChE, ALB, PTA, liver function, renal function, soluble complement receptor-1 (sCR1) and erythrocyte innate immune adhesion function (EIIAF) were regularly determined.</p><p><b>RESULTS</b>ChE in Group A,B,C was dropped obviously during the treatment (P less than 0.001, less than 0.001, 0.023=. But there were no change in ALB, PTA, sCR1, EIIAF (P greater than 0.05), and remarkable improvement of ALT, AST, TBiL was seen during the treatment in Groups A, B, C. After the treatment with OM, the level of ChE recovered soon.</p><p><b>CONCLUSION</b>Serum level of ChE significantly declined during the treatment of viral hepatitis with OM, but no change was found in ALB, PTA, sCR1, EIIAF while liver function tests showed better results. So the drop of ChE does not mean deprivation of patient's liver disease.</p>
