Efficacy of hepatitis B immunoglobulin in relation to the gene polymorphisms of human leukocyte Fcγ receptor III (CD16) in Chinese liver transplant patients

Background Although the use of hepatitis B immunoglobulin (HBIG) may lead to a significant reduction in recurrent hepatitis B virus (HBV) infection and improve the survival of patients who have undergone liver transplantation (LT) for hepatitis B-related diseases, the recurrence of the disease still remains at a lower level. Different clinical curative effects were observed in patients with the same HBV-related diseases and the same therapy. This study was undertaken to investigate whether the efficacy of HBIG is associated with FCGR3A gene polymorphisms in Chinese liver transplant patients.Methods Altogether 77 patients who had received liver transplantation for hepatitis B-related diseases with more than one-year survival after surgery were studied. The recurrence of HBV was characterized by the appearance of HBsAg in serum after the operation. The FCGR3A genotyping was performed using genomic DNA sequencing (ABI 3037). Single nucleotide polymorphism at nucleotide 559 was detected by Polyphred. Results Of the 77 patients, 14 were complicated with HBV recurrence post-transplant. The FCGR3A at nucleotide 559 TT was observed in 35 (45.5％) subjects, whereas TG in 31(40.3％) and GG in 11(14.3％). In the 559G carrier group (n=42, 54.5%), the risk of HBV recurrence was 9.5%, and 1- and 2-year recurrence-free survival rates were 95.2% and 88.7%, respectively. In the 559G noncarrier group (n=35, 45.5%), the risk of HBV recurrence was 28.6%, and 1- and 2-year recurrence-free survival rates were 74.3% and 69.3%, respectively. The risk of HBV recurrence and the recurrence-free survival rate were both statistically different between the 559G carrier and noncarrier groups (P&lt;0.05).Conclusions A single nucleotide polymorphism（T/G）at position 559 of the FCGR3A gene was found in Chinese patients. The efficacy of HBIG in prophylaxis of HBV recurrence after LT is associated with the gene polymorphism, so detecting FCGR3A genotypes can be a clinical reference of the HBIG administration.     

阿德福韦酯治疗拉米夫定耐药HBeAg（＋）慢性乙型肝炎临床观察

目的探讨阿德福韦酯治疗拉米夫定耐药HBeAg（＋）慢性乙型肝炎的疗效。方法 78例拉米夫定耐药的HBeAg（＋）慢性乙型肝炎患者随机分入ADV＋LAM联合组（A组）40例,予ADV 10mg/d＋LAM 100 mg/d;ADV组（B组）38例,予ADV 10mg/d。观察24周和48周时ALT复常率、HBV DNA转阴和HBV血清学标志物的变化。结果 A组在治疗24周和48周HBV DNA转阴率,均高于同期B组HBV DNA转阴率（60.0%vs 34.2%,P〈0.05）（、77.5%vs 50.0%,P〈0.05）,具有统计学意义。两组24周和48周ALT复常率、HBeAg转阴率和HBeAg血清学转换率差异无统计学意义。结论对于拉米夫定耐药的HBeAg（＋）慢性乙型肝炎加用或换用阿德福韦酯均可取得一定疗效。加用较换用阿德福韦酯能更好地抑制拉米夫定耐药的HBeAg（＋）慢性乙型肝炎患者HBV DNA。     

乙型肝炎患者血清乙型肝炎病毒-DNA与常用血清标志物的相关性分析

目的: 评估乙型肝炎(乙肝)患者血清乙肝病毒DNA(HBV-DNA)载量与血清免疫和生化标志物之间的关系。方法: 收集214例乙肝患者血清, 分别用荧光定量PCR法、化学发光法和速率法检测血清中的HBV-DNA、乙肝病毒表面抗原(HBsAg)、乙肝病毒e抗原(HBeAg)和丙氨酸氨基转移酶(ALT), 分析各标志物之间的关系。结果: 214例中, HBV-DNA阳性率为57.48%;HBeAg阳性率为28.04%。HBV-DNA载量与HBsAg和ALT水平均无相关关系(P>0.05), 但与HBeAg水平密切相关(P<0.01), HBV-DNA阳性组的HBeAg和ALT水平均明显高于HBV-DNA阴性组(P<0.01)。结论: HBV-DNA载量与HBeAg水平呈正相关关系, 与HBsAg和ALT水平无相关性, HBsAg水平作为HBV-DNA的替代方法仍需进一步验证。

拉米夫定预防肝移植术后乙型肝炎病毒再感染的作用

目的：探讨拉米夫定在预防肝移植术后乙型肝炎病毒（HBV）再感染中的作用。方法：40例HBV相关疾病患者肝移植术后常规采用拉米夫定预防HBV再感染,同时监测乙型肝炎血清标记物,血清HBV－DNA,YMDD区变异,肝活检组织乙型肝炎标记物免疫组化,结果：肝移植术后拉米夫定单一预防用药6个月HBV再感染率为12．2％,12个月再感染率为23．5％,4例患者HBV－DNA转阳性,其中3例YMDD区产生变异,订前HBV DNA阳性的患者在肝移植术后HBV再感染率高,而患者术前HBeAg的状态与肝移植术后HBV再感染无明显相关。结论：拉米夫定可以有效地预防肝移植术后HBV再感染,在拉米夫定用药的基础上HBV再感染可以产生YMDD区变异,HBV相关疾病患者行肝移植时术前应使HBV,DNA转阴性。     

A pilot study on the combined therapy of granulocyte-macrophage colony-stimulating factor and hepatitis B vaccine on chronic hepatitis B virus carrier children

Objective To observe the efficacy of treating intrauterine infected chronic hepatitis B virus (HBV) carrier children with a combination of granulocyte-macrophage colony-stimulating factor (GM-CSF) or hepatitis B immunoglobulin (HBIG) plus recombinant hepatitis B vaccine (rHBvac).Methods A total of 27 chronic HBV infected children, who were born to HBV carrier mothers and received hepatitis B immunoprophylaxis at birth, were randomized into 2 groups: one receiving a combined therapy of 50 μg of GM-CSF plus 10 μg of rHBvac injected intramuscularly at the same location (GM-CSF group, 14 children) or 200 IU HBIG and 10 μg rHBvac in different muscles (HBIG group, 13 children) on a monthly four-dose schedule. HBV-DNA quantification and other HBV serological markers were tested before and after the four-dose therapy. Results Twelve children in each group completed the study. Of them, 3 children in the GM-CSF group and 4 in the HBIG group had elevated serum alanine transaminase (ALT) before the trial, and then 2 in each group became ALT normal after the treatment. Before the therapy, hepatitis B e antigen (HBeAg) positivity was found in nine children in the GM-CSF group and 10 in the HBIG group. One from each group had an HBeAg/anti-HBe seroconversion after the treatment. The quantity of HBV-DNA was significantly lower after the treatment (P=0.023) in GM-CSF group, but was not significantly reduced in HBIG group. No subjects were found to be negative for hepatitis B surface antigen (HBsAg) after the treatment, and no serious adverse events occurred in either group. Conclusion Combined GM-CSF and rHBvac therapy inhibit HBV replication in carrier children who were not protected after treatment with immunoprophylaxis.     

慢性乙型肝炎病人血液单核细胞中HBV标志物的检出

本文报告在慢性乙型肝炎38例的外周血单核细胞(PBMC)和T、B淋巴细胞中检测到HBV标志物阳性29例(76.3％)。其中17例病人的PBMC中HBsAg,HBeAg和HBV-DNA阳性者分别为4,2和14例。21例病人分离出T,B淋巴细胞,其中T细胞中HBsAg,HBeAg与HBV-DNA阳性分别为2,2和1例;B细胞中分别为3,6,1例。血清HBV标志物阳性的病人其PBMC中这些标志物的检出率(13/15例)明显高于血清抗HBc和抗HBe阳性的稳定期病人(3/7例)。提示HBV可能感染和损害慢性乙型肝炎病人的淋巴细胞,这也许是乙型肝炎病人免疫功能异常的原因之一。

A randomized control trial on interruption of HBV transmission in uterus

Objective To study the interruptive effect of hepatitis B virus (HBV) specific immunolobulin (HBIG) before delivery in attempt to prevent intrauterine transmission of HBV.Methods Nine hundred and eighty HBsAg carrier pregnant women were randomly divided into HBIG group and control group. Each subject in the HBIG group received 200 IU or 400 IU of HBIG intramuscularly at 3, 2 and 1 month before delivery. The subjects in the control group did not receive any specific treatment. All newborn infants received 100 IU of HBIG intramascularty after venous blood samples were taken at birth and 2 weeks after birth, followed by 30 μg plasma-derived HB vaccine or 5 μg recombinant yeast-derived hepatitis B vaccine at 1, 2 and 7 months of age. Blood tests were performed for all the lying-in women and their neonates. Blood specimens were tested for HBsAg and HBeAg by enzyme immunoassay. All infants were followed up for 1 year.Results In the HBIG group, 491 neonates were born to 487 HBV carrier mothers; and in the control group, 496 neonates were born to 493 HBV carrier mothers. The rates of intrauterine transmission in the two groups were 14.3% and 5.7% respectively (χ2=20.280, P&lt;0.001), and the rates of chronic hepatitis B in the two groups were 2.2% and 7.3% respectively (χ2=13.696, P&lt;0.001). The high risk factors of intrauterine HBV infection included HBsAg HBeAg double positive and HBV DNA positive in the peripheral blood of pregnant women.Conclusion HBV infection in the uterus may be interrupted by injecting multiple intramuscular HBIG injections before delivery without causing any side-effects.
