The Impact

Abstract Background Current clinical guidelines recommend treating chronic hepatitis B virus (HBV) infection in a minority of cases, but there are relatively scarce data on evolution or progression of liver inflammation and fibrosis in cases of chronic HBV (CHB) that do not meet treatment criteria. We aimed to assess the impact of TDF on liver disease, and the risk of renal impairment in treated CHB patients in comparison to untreated patients. Methods We studied a longitudinal ethnically diverse CHB cohort in the UK attending out-patient clinics between 2005 and 2018. We examined TDF treatment (vs. untreated) as the main exposure, with HBV DNA viral load (VL), ALT, elastography scores and eGFR as the main outcomes, using paired tests and mixed effects model for longitudinal measurements. Additionally, decline of eGFR during follow-up was quantified within individuals by thresholds based on clinical guidelines. Baseline was defined as treatment initiation for TDF group and the beginning of clinical follow-up for untreated group respectively. Results We included 206 adults (60 on TDF, 146 untreated), with a median ± IQR follow-up duration of 3.3 ± 2.8 years. The TDF group was significantly older (median age 39 vs. 35 years, p = 0.004) and more likely to be male (63% vs. 47%, p = 0.04) compared to the untreated group. Baseline difference between TDF and untreated groups reflected treatment eligibility criteria. As expected, VL and ALT declined significantly over time in TDF-treated patients. Elastography scores normalised during treatment in the TDF group reflecting regression of inflammation and/or fibrosis. However, 6/81 (7.4%) of untreated patients had a progression of fibrosis stage from F0-F1 to F2 or F3. There was no evidence of difference in rates or incidence of renal impairment during follow-up in the TDF vs. untreated group. Conclusions Risk of liver inflammation and fibrosis may be raised in untreated patients compared to those receiving TDF, and TDF may benefit a larger percentage of the CHB population.

Background:Targeted synthetic DMARDs (ts-DMARDs) are becoming more available and affordable in developing countries, where the prevalence of hepatitis B virus (HBV) infection is still an important public health issue. The safety of ts-DMARDs therapy in terms of the reactivation of hepatitis B virus (HBV) infection need more concern. Rare data from a prospective study focus on the use of ts-DMARDs in patients with concurrent rheumatoid arthritis (RA) and HBV infection were available by now.Objectives:To evaluate the influence of tofacitinib on reactivation of HBV infection in HBsAg carriers with RA.Methods:In this 52 weeks observation, HBsAg carriers with active RA (DAS28>5.1) despite failed combined treatment with MTX and other non-biological DMARDs were enrolled. Patients must have normal liver function prior to study. All patients received therapy with tofacitinib (5mg twice daily) and concomitant MTX (10-12.5mg/w). Entecavir was prescribed preventively for patients who had a baseline HBV load >2000 copy/ml (group 1), and Lamivudin for patients with HBV load ≤ 2000 copy/ml (group 2). Liver enzymes (AST/ALT) and HBV viral load were monitored every 4 weeks. Increased viral load and abnormal liver function were managed according to expert opinion.Results:Thirteen patients (10 female) were recruited. Nine patients had a baseline viral load >2000 copy/ml (group 1, with preventive Entecavir), and the other 4 patients had a viral load ≤ 2000 copy/ml (group 2, with preventive Lamivudin). Two patients from group 1 discontinued tofacitinib at week 12 due to ineffectiveness, and both continued taking Entecavir for another 3 months after the discontinuation of tofacitinib.No reactivation of hepatitis B was observed in patients from group 1. One patients (female, 54 years old) from group 2 underwent a mild increase of both ALT and AST (67 and 56 IU/L, respectively) at week 16. An elevated viral load (4.9e6 copies/ml, baseline 1.4e3) and a HBV YMDD mutant was also found. The tofacitinib treatment continued. After prescription of Adefovir (combined with the pre-existing Lamivudin), both liver enzyme and viral load decreased to normal range in 8 weeks and remained normal throughout the study.Conclusion:An aggressive Tofacitinib + MTX therapy may be a safe option for HBsAg carriers with cs-DMARDs refractory RA. More active and effective prophylaxis strategy may be recommended to reduce the risk of HBV reactivation during the treatment.References:[1]Chen YM, Huang WN, Wu YD, et al.

Purpose The role of antiviral prophylaxis in preventing hepatitis B virus (HBV) reactivation before rituximab-based chemotherapy in patients with lymphoma and resolved hepatitis B is unclear. Patients and Methods Eighty patients with CD20+ lymphoma and resolved hepatitis B were randomly assigned to receive either prophylactic entecavir (ETV) before chemotherapy to 3 months after completing chemotherapy (ETV prophylactic group, n = 41) or to receive therapeutic ETV at the time of HBV reactivation and hepatitis B surface antigen (HBsAg) reverse seroconversion since chemotherapy (control group, n = 39). Results Fifty-eight patients (72.5%) were positive for hepatitis B surface antibody, and HBV DNA was undetectable in 50 patients (62.5%). During a mean 18-month follow-up period, one patient (2.4%) in the ETV prophylactic group and seven patients (17.9%) in the control group developed HBV reactivation (P = .027). The cumulative HBV reactivation rates at months 6, 12, and 18 after chemotherapy were 8%, 11.2%, and 25.9%, respectively, in the control group, and 0%, 0%, and 4.3% in the ETV prophylactic group (P = .019). Four patients (50%) in the control group had HBsAg reverse seroconversion after HBV reactivation. The cumulative HBsAg reverse seroconversion rates at months 6, 12, and 18 since chemotherapy were 0%, 6.4%, and 16.3% in the control group, respectively, which were significantly higher than those in the ETV prophylactic group (P = .032). Patients with detectable or undetectable viral load could develop HBV reactivation and HBsAg reverse seroconversion. Conclusion Undetectable HBV viral load before chemotherapy did not confer reactivation-free status. Antiviral prophylaxis can potentially prevent rituximab-associated HBV reactivation in patients with lymphoma and resolved hepatitis B.

Introduction: Liver regeneration is a heterogeneous process involving proliferation of different cell types in response to injury. Bone marrow derived stem cells may be involved in this process, by making contribution to parenchymal restoration and cellular replacement. We aimed to investigate the correlation between level of circulating mobilized CD34+ hematopoietic stem progenitor cells (HSPCs) and viremia level in patients chronically infected with hepatitis B virus (HBV). Methods: Blood samples were prospectively collected for assessing percentage and absolute counts of circulating CD34+ HSPCs and viral load level using flow cytometry and RT-PCR respectively. Patients with chronic hepatitis B (CHB) (n = 30), Entecavir (ETV) treated subjects (n = 30) and 20 age and gender matched healthy controls were enrolled in this study. Results were expressed as mean ± SD. Results and discussion: A significant increase in circulating CD34+ HSPCs level was observed in CHB patients (5 ± 3.1, 324 ± 195 × 103/ml) as compared to ETV treated subjects (0.57 ± 0.27,1022 ± 325) and healthy controls (0.53 ± 0.37, 694 ± 254, P < 0.001) in regards to percentage and absolute counts respectively. Levels of CD34+ HSPCs strongly and positively correlated with HBV DNA viral load levels in CHB patients (r2 = 0.8417, 0.649, P < 0.001).Thus, in chronic liver disorders (CHB), when reduced regenerative capacity of hepatocytes is reached, BMSCs mobilization occurs and their level increases in peripheral blood. The level of circulating CD34+ cells in peripheral blood of CHB patients paralleled with the hepatitis B viral load.
