“…20 patients whose HBV DNA level and ALT were normal but HBV serological detection were abnormal (12 was HBsAg+HBcAb+HBeAb+, and 8 were HBsAg+HBcAb+HBeAg+), they also received preventive entecavir treatment. All the patients with HBV infection were analyzed for HBV serum test and the active infection patients were analyzed HBV DNA content before every cycle and all the patients needed to underwent regular analyses of blood and liver (especially ALT) and kidney function ( Table 2 ) [ 20 , 21 ].…”

ObjectivesThis study aimed to determine the HBV infection status of 135 patients with DLBCL (diffuse large B cell lymphoma), to analyze the overall survival (OS) and progression-free survival (PFS) of the different HBV infection status groups, and to discuss the relationship between HBV serological test results and the prognosis of DLBCL patients.MethodsA retrospective analysis was performed of the clinical data, HBV serological test results, and PFS/OS of 135 DLBCL patients who were initially diagnosed and treated with more than 3 cycles of an R-CHOP/CHOP/CHOP-like regimen at our center from January 1, 2008 to December 31, 2012.ResultsThe patients in the HBV infection group were older at disease onset (≥60 years old) and were more likely to present with stage 3-4 disease compared with the HBV-free group (P = 0.030 and P = 0.025, respectively). Approximately 50% of the patients with an active HBV infection required a reduction in the chemotherapy dose, and 66.7% of the patients in this group received more than 1 line of therapy; these rates were significantly higher than those in the no infection group (P = 0.003 and P = 0.011, respectively). Although HBV infection had no obvious influence on the outcome of first-line therapy, patients with an inactive infection had a higher relapse/progression rate within 3 months after a CR/PR than patients with an active infection (14/20 vs. 1/12, P = 0.001). The PFS at 1 year, 3 years and OS rates at 1 year, 3 years were significantly lower in the active HBV infection group than in the HBV-free group (P = 0.008, P = 0.002, P = 0.004, and P = 0.002, respectively). The PFS rates at 1 year and 3 year in HBV-free group were higher than those in the HBV infection group (80.5% and 52.9% P = 0.001, 78.1% and 44.4% P = 0.002). The lymphoma-related mortality rates were 2.7% in the no infection group, 19.2% in the HBV infection group (P = 0.004), and 28.6% in the active HBV infection group (P = 0.001). Among the patients treated with MabThera, the PFS in the HBV infection group was 11 months in the HBV infection group and 67 months in the infection-free group (P = 0.000). A Cox regression model of PFS revealed that age ≥60 years and HBV infection were independent prognostic factors (age: P = 0.019, HR = 2.002, 95% CI 1.123-3.567; HBV infection: P = 0.026, HR = 0.494, 95% CI 0.265-0.919).ConclusionCompared with the patients in HBV-free group, those in the HBV infection group were older at disease onset, and the active infection patients presented with more advanced disease and had a lower PFS at 1, 3 years as well as a lower OS at 3 years. The patients in the inactive infection group had a higher progression/relapse rate within 3 months after a CR/PR than those in the active infection group. HBV infection was an unfavorable factor for PFS in the MabThera group. An age ≥60 years and HBV infection were independent unfavorable prognostic factors for PFS.

“…The association between HBV and non-Hodgkin lymphoma has been well investigated[ 181 , 182 ]. In a study conducted by Elbedewy et al[ 182 ] in Egypt, HBV DNA was detected in 5/72 (6.94%) of patients with diffuse large B-cell lymphoma who were positive for anti HBc (191). In a study conducted by Kamyar et al[ 183 ] in Ahvaz, Iran, HBV DNA was isolated in 3/12 (25%) of patients with Hodgkin lymphoma and in 7/ 29 (24.13%) of patients with non-Hodgkin lymphoma.…”

The event of mutations in the surface antigen gene of hepatitis B virus (HBV) results in undetectable hepatitis B surface antigen with positive/negative anti-hepatitis B core (anti-HBc) antibody status in serum and this phenomenon is named occult hepatitis B infection (OBI). The presence of anti-HBc antibody in serum is an important key for OBI tracking, although about 20% of OBI cases are negative for anti-HBc antibody. The diagnosis of OBI is mainly based on polymerase chain reaction (PCR) and real-time PCR assays. However, real-time PCR is a more reliable method than PCR. OBI is a great issue for the public health problem and a challenge for the clinical entity worldwide. The persistence of OBI may lead to the development of cirrhosis and hepatocellular carcinoma. With regard to OBI complications, the screening of HBV DNA by the highly sensitive molecular means should be implemented for: (1) patients with a previous history of chronic or acute HBV infection; (2) patients co-infected with hepatitis C virus/human immunodeficiency virus; (3) patients undergoing chemotherapy or anti-CD20 therapy; (4) recipients of organ transplant; (5) blood donors; (6) organ transplant donors; (7) thalassemia and hemophilia patients; (8) health care workers; (9) patients with liver related disease (cryptogenic); (10) hemodialysis patients; (11) patients undergoing lamivudine or interferon therapy; and (12) children in time of HBV vaccination especially in highly endemic areas of HBV. Active HBV vaccination should be implemented for the close relatives of patients who are negative for OBI markers. Thus, the goal of this review is to evaluate the rate of OBI with a focus on status of high risk groups in different regions of the world.

“…23,24 Individuals with negative HBsAg assay are not completely free of the risk of reactivation of hepatitis since viral DNA and HBcAb may persist as an occult hepatitis B infection (OBI). 25 That is to say, patients with HBsAg seronegativity who infected HBV previously indicates the clearance of natural HBV infection. But to a certain degree, virus replication may remain without HBsAg seropositivity.…”

Background: China is a high endemic area for the hepatitis B virus (HBV). The studies established the epidemiology between HBV and diffuse large B-cell lymphoma (DLBCL), but further research is necessary to clarify the potential link between HBV and DLBCL. Patients and Methods: A total of 319 patients diagnosed with DLBCL were recruited as cases at First Medical Centre of Chinese PLA General Hospital from September 2010 to December 2018. During the same time, two age-and sex-matched controls were selected for each case, and the control groups comprised of 319 patients with non-hematological malignancy and 319 subjects with non-malignant conditions. Relative risk of developing DLBCL among individuals tested positive for hepatitis B surface antigen was calculated. After that, we retrospectively analyzed clinical data from DLBCL patients with different HBV infection statuses. Results: The HBV infection rate of patients with DLBCL (11.60%) was significantly higher than the other two control groups (5.02% and 4.08%), indicating the risk of DLBCL may increased in HBV infections. Meanwhile, this study demonstrated an independent association between HBV infection and poorer clinical outcomes. Conclusion: Our study demonstrated that HBV infection may play an important role in the pathogenesis of DLBCL and show poor outcomes in HBV-endemic China.
