Analysis of clinical characteristics of 22 906 gravidas with Hepatitis B Virus infection / 实用医学杂志

Objective To analyze the clinical characteristics of gravidas with HBV in Nanfang Hospital from 2008 to 2014. Methods 22 906 gravidas were retrospectively investigated. Results The HBsAg positive rates were 11.64% and 6.16% when the gravidas were divided into Cantonese and non-Cantonese groups (χ2 =193.370, P < 0.005). The ALT abnormal rates in HBeAg positive and HBeAg negative gravidas were 17.96% and 6.68% (χ2=62.594, P<0.005). Conclusion The HBsAg positive rate of gravidas in Guangdong and the ALT abnormal rate of HBeAg positive gravidas are higher.

Treatment options in HBeAg-positive chronic hepatitis B patients with a poor response to 24-week interferon monotherapy / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of 4 treatment options for HBeAg-positive chronic hepatitis B (CHB) patients following a suboptimal response to 24-week interferon monotherapy.</p><p><b>METHODS</b>The data of 193 HBeAg-positive CHB patients with suboptimal response to 24-week interferon monotherapy were collected from Nanfang Hospital between September, 2010 and January, 2013. According to the subsequent treatments, the patients were divided into group A with additional entecavir or adefovir, group B with further interferon monotherapy, group C with conversion to NAs therapy, and group D with direct therapy withdrawal, and the biochemical and virological results at weeks 24, 48 and 72 were analyzed in the 4 groups.</p><p><b>RESULTS</b>At week 48, the HBV DNA negative rates and serum alanine aminotransferase (ALT) normalization rates were both significantly higher in group A and C than in group B (P<0.05); in group A, ETV therapy subgroup had a significantly higher HBV DNA negative rate than ADV therapy subgroup at week 48 (90.3% vs 59.5%, Χ=8.255, P=0.004). At week 72, 39.7%(27/68) of the patients in group A achieved HBeAg seroconversion, a rate significantly higher than those in groups B (Χ=4.238, P=0.040) and C (Χ=7.681, P=0.006); the HBV DNA negative rate and ALT normalization rate in group A were 85.3%(58/68) and 86.8%(59/68), respectively, both significantly higher than those in group B (Χ=23.018, P<0.001; Χ=5.987, P=0.014) but comparable to those in group C (P>0.05). In the two subgroups in group A, the HBV DNA negative rate and HBeAg seroconversion rate were both significantly higher in ETV subgroup (Χ=9.823, P=0.002; Χ=5.450, P=0.020). In group D, all the patients remained HBeAg-positive with abnormal ALT levels and high level of HBV DNA.</p><p><b>CONCLUSION</b>For HBeAg-positive CHB patients with suboptimal response to 24-week interferon monotherapy, combined treatment with NAs (especially ETV) and extension of the treatment course can significantly improve the HBeAg seroconversion rates, HBV DNA negative rates, and ALT normalization rates.</p>

Clinical analysis of chronic hepatitis B with concurrent hepatitis e antigen and antibody during antiviral therapy / 实用医学杂志

Objective To evaluate the clinical significance of chronic hepatitis B (CHB) with concurrent hepatitis e antigen (HBeAg) and antibody (anti-HBe) during antiviral therapy. Methods A total of 115 CHB patients with concurrent HBeAg and anti-Hbe detection during antiviral therapy were enrolled in this retrospective study. All patients received pegylated-IFN-alpha-2a (Peg-IFNα-2a, n = 50) or entecavir (ETV, n = 65) for antiviral treatment. Their biochemical virological and serological response and clinical outcome were detected and analyzed. Results Among the patients treated with Peg-IFNα-2a, 31 (62.0%) achieved HBeAg seroconversion and 6 (12.0%) achieved HBsAg seroconversion at the end of treatment. About 35.4% of patients, who received ETV, achieved HBeAg seroconversion and none of them achieved HBsAg seroconversion at the end of treatment (P < 0.05). Conclusion High rates of HBeAg seroconversion and HBsAg loss could be achieved in CHB patients, with co-existence of HBeAg and anti-HBe, who received Peg-IFNα-2a, but not ETV therapy.
