BACKGROUND:

Reactivation of hepatitis B virus (HBV) after rituximab‐containing chemotherapy in patients with B‐cell lymphoma has been recognized as a potentially serious complication in HBV immune patients.

METHODS:

To determine the HBV reactivation in patients treated with rituximab, a retrospective study of HBV‐related markers was performed before and after rituximab‐containing treatment in 261 consecutive patients with CD20‐positive B‐cell lymphoma.

RESULTS:

Of the 261 patients, 230 patients were tested for both hepatitis B surface antigen (HBsAg) and antibody to hepatitis B core antigen (anti‐HBc) before treatment. Fifty‐six (24.3%) of 230 patients were anti‐HBc positive, and the remaining 174 (75.6%) patients were anti‐HBc negative. Among the 56 anti‐HBc–positive patients, 5 (8.9%) became HBsAg positive (HBV reactivation), whereas none of the 174 anti‐HBc–negative patients became HBsAg positive with a median follow‐up of 24 months (P = .001). Among the 5 patients with HBV reactivation, 4 were negative for antibody to HBsAg (anti‐HBs), and 1 patient was positive for anti‐HBs. All 5 of these patients were treated successfully with entecavir on detection of HBsAg, although 4 of the 5 patients exhibited mild to moderate elevation of alanine aminotransferase. Among 56 anti‐HBc–positive patients, those negative for anti‐HBs had a higher probability of developing HBV reactivation compared with those positive for anti‐HBs (4 of 19; 21.1% vs 1 of 37; 2.7%, P = .014).

CONCLUSIONS:

Patients with isolated anti‐HBc are at high risk of HBV reactivation and should be monitored closely for HBsAg, anti‐HBs, HBV‐DNA, and transaminase levels during and after rituximab‐containing treatment. Although preemptive use of entecavir enabled successful management of HBV reactivation, mild to moderate hepatic flare was still observed. These approaches should be further evaluated in a prospective study with regard to clinical usefulness, safety, and cost‐effectiveness. Cancer 2010. © 2010 American Cancer Society.  相似文献

肝癌高发区抗-HBc阳性慢性乙肝患者HBVDNA血清学分析   总被引:2,自引:0,他引:2  
目的:了解启东肝癌高发区抗-HBc阳性慢性乙肝患者HDVDNA分布 情况。方法:采用ELISA法筛选慢性乙肝患者中抗-HBc阳性者,再用聚合酶链反应(PCR)检测这些血清中的HBVDNA。结果:HBVDNA总检出率为75.24%(158/210)。抗-HBc与HBsAg、HBeAg同在时HBVDNA阳性率最高,达97.26%(71/73),显著高于其它模式(P<0.005)。抗-HBc/HBsAg阳性血清中HBVDNA检出率为81.08%(150/185),单纯抗HBc/HBsAg阳性血清中HBVDNA检出率为80.77%(42/52),单纯抗-HBc阳性血清中检出率为20%(1/5)。结论:抗-HBc是乙肝病毒感染的一个直接标志。判断患者的传染性应通过免疫学和基因学两种方法来检测。启东慢性乙肝患者中HBVDNA整合现象可能要高于其它地区,这或许是启东肝癌高发的机制之一,值得进一步研究。基因学和免疫学方法检测乙肝病毒感染情况各有利弊,应互补共存。  相似文献

Aim: The effect of transcatheter arterial chemoembolization (TACE) therapy on hepatitis B virus (HBV) reactivation in hepatocellular carcinoma (HCC) patients with prior resolved hepatitis B is not fully understood. Methods: From January 2006 to December 2010, 43 hepatitis B surface antigen (HBsAg)‐negative/anti‐hepatitis B core antigen (HBc) positive patients with newly diagnosed unresectable HCC were enrolled in the study. All underwent TACE therapy. Results: Four patients (9.3%) developed HBV reactivation with mild/moderate hepatitis. The median number of TACE cycles received was 3.5 (range 3–4 cycles). The median time interval between the occurrence of HBV reactivation and the completion of TACE therapy was 3 months (range 1–5 months) and their median HBV DNA level was 1.58 × 104 IU/mL (range, 1.65 × 103–6.42 × 104 IU/mL). After the introduction of lamivudine at the occurrence of HBV reactivation, all had resolution of hepatitis. An exploratory analysis indicated that significant predictors of HBV reactivation included increased serum total bilirubin coexisting with cirrhosis and the total number of cycles of TACE received. Conclusion: The administration of TACE therapy may increase the risk of HBV reactivation in HBsAg‐negative/anti‐HBc‐positive patients diagnosed with unresectable HCC. Further studies are warranted to explore the optimal management of HBV reactivation in patients with prior resolved hepatitis B.  相似文献

Adoptive transfer of immunity against hepatitis B surface antigen (HBsAg) was previously shown to facilitate suppression of experimental human hepatocellular carcinoma (HCC) expressing HBsAg in athymic mice. We have shown that oral tolerance induces antigen‐specific immune suppression of HBsAg by feeding hepatitis B virus (HBV) antigens. In the present study we evaluated the effect of oral tolerance induction toward HBV or HCC antigens on the growth of experimental HCC‐expressing HBsAg in mice. Tolerance induction was induced in mice by 5 oral feedings of 1 μg HBV antigens or HCC‐extracted proteins (50 μg protein) before vaccination with recombinant HBsAg. Splenocytes (2 × 106) from these mice were transferred to sublethally irradiated athymic BALB/c mice previously transplanted subcutaneously with 107 human hepatoma Hep3B cells. Adoptive transfer of splenocytes immunized toward HBsAg prevented tumor growth. At 4 weeks after splenocyte transplantation, tumor volume and serum alpha‐fetoprotein (AFP) levels in athymic mice transplanted with splenocytes immunized to HBsAg were undetectable as compared with 1,048 ± 738 mm3 and 2,500 ± 1,431 ng/ml in recipients of naïve splenocytes (p < 0.0001). Mice receiving splenocytes tolerized toward Hep3B cells, as manifested by reduced serum HBs antibody levels, reduced HBV‐specific stimulation index and reduced HBV‐specific‐IFNγ spot‐forming cells, had early tumor growth evident by elevated AFP serum levels, weight loss and mortality, which were suppressed at 6 weeks. Mice transplanted with splenocytes tolerized toward HBV antigens did not have direct evidence of tumor growth. Induction of oral tolerance toward HCC‐extracted proteins enabled transient tumor growth in this model. This effect was mediated through downregulation of the anti‐HBV immune response. © 2002 Wiley‐Liss, Inc.  相似文献

Thirty-four patients from the Philadelphia area with hepatocellular carcinoma (HCC) were matched with colon cancer patients, lung cancer patients and blood donors according to age and sex. Sera from the four groups were tested to determine the prevalence of hepatitis B surface antigen (HBsAg), antibody to HBsAg (anti-HBs), and antibody to hepatitis B core antigen (anti-HBc). Five of the HCC patients (14.7%) and none of the controls were positive for HBsAg. At least one of the three serologic markers of hepatitis B virus (HBV) infection was found in 51.5% of the HCC patients, 5.3% of the colon cancer patients, 11.1% of the lung cancer patients, and 10.7% of the blood donors. Twelve of the seventeen seropositive HCC patients (70.6%) were positive for anti-HBc alone, while all of the seropositive lung cancer patients and donors were positive for anti-HBs alone. Sera positive for any HBV marker were also tested for e antigen (HBeAg) and its antibody (anti-HBe). Four of the HCC patients (23.5% of the seropositives) had anti-HBe, while none of the sera tested had HBeAg. A history of alcoholism did not appear to influence HBV seropositivity in the HCC patients. This study supports the hypothesis that HBV infection is closely associated with HCC even in areas where both conditions are uncommon. The wide disparity between seropositivity for HBsAg and anti-HBc in the HCC patients is an unusual feature, for which an age effect may be the best explanation.  相似文献

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. Hepatitis B virus is the causative agent for chronic, acute, cirrhosis, and hepatocellular carcinoma.  SLE patients with chronic or occult hepatitis B infection undergoing immunosuppressive drugs may become reactive and develop fatal hepatitis. Therefore, this study was conducted to determine HBV markers in SLE patients before the administration of immunosuppressive drugs in Ahvaz city, Iran. Materials and methods: The sera of 92 SLE patients were  tested for HBs Ag and anti-HBc using ELISA, HBV DNA (by Nested PCR) testes. Real-time PCR was performed for the patients with positive anti-HBc and negative HBsAg. The positive HBV DNA samples were checked for HBV genotype and HBV subtypes. Results: Among the 92 SLE patients, three (3.3%) were males and 89 (96.7%) females . The patients’ ages ranged from 14 to 70 years [mean age of 38.9±10.1]. Three of 92 (3.26%) subjects [2/3 males and 1/89 female] were positive for HBsAg, anti-HBc Ab, and HBV DNA detected with PCR (p=0.000003)].  Five of 89 (5.61%) subjects [1 male and 4/88 females were only positive for anti-HBc and negative for HBs Ag, HBV DNA(PCR) using Real-time PCR (p=0.05).  The results of the nucleotide data and phylogenetic tree showed all three HBV patients were genotype D1. The results of amino acid sequencing revealed all three HBV patients were HBV subtype ayw2. Conclusion: This study proved that 3.26% of SLE patients were positive for overt HBV infection (positive for anti-HBc, HBsAg and HBV-DNA using PCR). All the three isolated HBV were genotype D1 and subtype ayw2. The fact that 5.61% of  the patients were only positive for anti-HBc characterized the occult hepatitis B infection (OBI) although further investigation is needed. To prevent HBV or OBI reactivation for SLE patients before immunosuppression treatment, HBV markers including anti-HBc, HBsAg, HBV-DNA should be implemented using PCR and Real-time PCR .  相似文献

Objective: To investigate the potential linkage between high rate of p16 methylation and hepatitis B virus (HBV) infection, methylation status of p16, HBV infection markers in serum and HBV-DNA replication level in cancerous and non-cancerous tissue of 32 cases of hepatocellular carcinomas (HCC) with HBV infection and 12 HCCs without HBV infection were examined. Methods: p16 methylation was detected with methylation-specific polymerase Chain reaction (PCR), and HBV markers were examined with real-time PCR and immunologic method. Results: Methylation of p16 promoter was found in 31 (70.5%) of 44 cancerous tissues of HCC, 2 (16.7%) of 12 HCC without HBV infection, 29 (90.6%) of 32 HCCs with HBV infection marker, p16 methylation was detected in 5 (83.3%) of 6 HCCs positive for HBsAg and HBeAg, 17 (94.4%) of 18 HCCs positive for HBsAg and negative for HBeAg, 7/8 (87.5%) of HCCs positive for other HBV infection markers, such as HBsAB, HBcAb, HBeAb. p16 methylation products were also found in non-cancerous tissues of 4 cases of HCCs with HBV infection, not detected in non-cancerous tissues without HBV infection. HBV-DNA was detected in cancerous tissues of 29/32 (90%) HCCs with HBV infection. Surprisingly, Methylation product of p16 promoter was found in all cases (29/29) of HCCs with detectable HBV-DNA in neoplastic tissue. Conclusion: Persistent HBV infection may promote p16 hypermethylation, suggesting that HBV, via enhancing the aberrant methylation of p16, indirectly involved in development of HCC.  相似文献
