BACKGROUND Although the benefits of antiviral therapy for hepatitis B virus(HBV)-related hepatocellular carcinoma(HCC)have been proven,researchers have not con-firmed the differences in patient outcomes between patients who received preoperative antiviral therapy for a period of time(at least 24 wk)and patients who received remedial antiviral therapy just before radical resection for HBV-related HCC.AIM To investigate the efficacy of perioperative remedial antiviral therapy in patients with HBV-related HCC.METHODS A retrospective study of patients who underwent radical resection for HBV-related HCC at the First Affiliated Hospital of Xi’an Jiaotong University from January 2016 to June 2019 was conducted.Considering the history of antiviral therapy,patients were assigned to remedial antiviral therapy and preoperative antiviral therapy groups.RESULTS Kaplan–Meier analysis revealed significant differences in overall survival(P<0.0001)and disease-free survival(P=0.035)between the two groups.Multivariate analysis demonstrated that a history of preoperative antiviral treatment was independently related to improved survival(hazard ratio=0.27;95%confidence interval:0.08-0.88;P=0.030).CONCLUSION In patients with HBV-related HCC,it is ideal to receive preoperative long-term antiviral therapy,which helps patients tolerate more extensive hepatectomy;however,remedial antiviral therapy,which reduces preoperative HBV-DNA levels to less than 4 Log10 copies DNA/mL,can also result in improved outcomes. 展开更多

The risk of reactivation in patients with chronic or past/resolved hepatitis B virus(HBV)infection receiving chemotherapy or immunosuppressive drugs is a wellknown possibility.The indication of antiviral prophylaxis with nucleo(t)side analogue is given according to the risk of HBV reactivation of the prescribed therapy.Though the advent of new drugs is occurring in all the field of medicine,in the setting of hematologic malignancies the last few years have been characterized by several drug classes and innovative cellular treatment.As novel therapies,there are few data about the rate of HBV reactivation and the decision of starting or not an antiviral prophylaxis could be challenging.Moreover,patients are often treated with a combination of different drugs,so evaluating the actual role of these new therapies in increasing the risk of HBV reactivation is difficult.First results are now available,but further studies are still needed.Patients with chronic HBV infection[hepatitis B surface antigen(HBsAg)positive]are reasonably all treated.Past/resolved HBV patients(HBsAg negative)are the actual area of uncertainty where it could be difficult choosing between prophylaxis and pre-emptive strategy. 展开更多

BACKGROUND Models for predicting hepatitis B e antigen(HBeAg)seroconversion in patients with HBeAg-positive chronic hepatitis B(CHB)after nucleos(t)ide analog treatment are rare.AIM To establish a simple scoring model based on a response-guided therapy(RGT)strategy for predicting HBeAg seroconversion and hepatitis B surface antigen(HBsAg)clearance.METHODS In this study,75 previously treated patients with HBeAg-positive CHB underwent a 52-week peginterferon-alfa(PEG-IFNα)treatment and a 24-wk follow-up.Logistic regression analysis was used to assess parameters at baseline,week 12,and week 24 to predict HBeAg seroconversion at 24 wk post-treatment.The two best predictors at each time point were used to establish a prediction model for PEG-IFNαtherapy efficacy.Parameters at each time point that met the corresponding optimal cutoff thresholds were scored as 1 or 0.RESULTS The two most meaningful predictors were HBsAg≤1000 IU/mL and HBeAg≤3 S/CO at baseline,HBsAg≤600 IU/mL and HBeAg≤3 S/CO at week 12,and HBsAg≤300 IU/mL and HBeAg≤2 S/CO at week 24.With a total score of 0 vs 2 at baseline,week 12,and week 24,the response rates were 23.8%,15.2%,and 11.1%vs 81.8%,80.0%,and 82.4%,respectively,and the HBsAg clearance rates were 2.4%,3.0%,and 0.0%,vs 54.5%,40.0%,and 41.2%,respectively.CONCLUSION We successfully established a predictive model and diagnosis-treatment process using the RGT strategy to predict HBeAg and HBsAg seroconversion in patients with HBeAg-positive CHB undergoing PEG-IFNαtherapy. 展开更多

Globally,hepatocellular carcinoma(HCC)is among the most prevalent and deadly cancers.Hepatitis B virus(HBV)infection is an important etiology and disease progression factor for HCC.Hepatectomy is a widely accepted curative treatment for HCC,but the long-term survival rate is still unsatisfactory due to the high recurrence rate after resection.Preoperative or postoperative antiviral therapy plays an important role in improving the prognosis for HBV-related HCC patients who underwent hepatectomy.However,many patients miss out on the chance to receive long-term preoperative antiviral medication because their HBV and HCC infections are discovered concurrently,necessitating the start of remedial antiviral therapy in the perioperative phase.Therefore,it is of great value to know when antiviral therapy is more appropriate and whether perioperative rescue antiviral therapy can achieve the effect of preoperative long-term antiviral therapy. 展开更多

Hepatitis due to hepatitis B virus(HBV)reactivation can be serious and potentially fatal,but is preventable.HBV reactivation is most commonly reported in patients receiving chemotherapy,especially rituximab-containing therapy for hematological malignancies and those receiving stem cell transplantation.Patients with inactive and even resolved HBV infection still have persistence of HBV genomes in the liver.The expression of these silent genomes is controlled by the immune system.Suppression or ablation of immune cells,most importantly B cells,may lead to reactivation of seemingly resolved HBV infection.Thus,all patients with hematological malignancies receiving anticancer therapy should be screened for active or resolved HBV infection by blood tests for hepatitis B surface antigen(HBsAg)and antibody to hepatitis B core antigen.Patients found to be positive for HBsAg should be given prophylactic antiviral therapy.For patients with resolved HBV infection,there are two approaches.The first is pre-emptive therapy guided by serial HBV DNA monitoring,and treatment with antiviral therapy as soon as HBV DNA becomes detectable.The second approach is prophy-lactic antiviral therapy,particularly for patients receiving high-risk therapy,especially anti-CD20 monoclonal antibody or hematopoietic stem cell transplantation.Entecavir and tenofovir are the preferred antiviral choices.Many new effective therapies for hematological malignancies have been introduced in the past decade,for example,chimeric antigen receptor(CAR)-T cell therapy,novel monoclonal antibodies,bispecific antibody drug conjugates,and small molecule inhibitors,which may be associated with HBV reactivation.Although there is limited evidence to guide the optimal preventive measures,we recommend antivi-ral prophylaxis in HBsAg-positive patients receiving novel treatments,including Bruton’s tyrosine kinase inhibitors,B-cell lymphoma 2 inhibitors,and CAR-T cell therapy.Further studies are needed to determine the risk of HBV reactivation with these agents and the best prophylactic strategy. 展开更多

BACKGROUND The interruption of mother-to-child transmission(MTCT)is considered important to decrease the individual and population morbidity of hepatitis B virus(HBV)infection as well as the global burden of hepatitis B.Serum vitamin D(VD)is associated with hepatitis B.AIM To assess whether baseline VD levels and single nucleotide polymorphisms of the VD receptor gene(VDR SNPs)are associated with the efficacy of tenofovir disoproxil fumarate(TDF)in the prevention of MTCT in pregnant women with high HBV viral loads.METHODS Thirty-eight pregnant women who were at high risk for MTCT of HBV(those with an HBV DNA level≥2×10^(5)IU/mL during 12-24 wk of gestation)receiving antiviral therapy of TDF between June 1,2019 and June 30,2021 in Mianyang were included in this retrospective study.The women received 300 mg TDF once daily from gestational weeks 24-28 until 3 mo after delivery.To further characterize the clinical relevance of maternal serum HBV DNA levels,we stratified patients according to HBV DNA level as follows:Those with levels<2×10_(5)(full responder group)vs those levels≥2×10^(5)IU/mL(partial responder group)at delivery.Serum levels of 25-hydroxyvitamin D[25(OH)D],liver function markers,virological parameters,VDR SNPs and other clinical parameters were collected to analyze their association with the efficacy of TDF.The Mann-Whitney U test or t test was used to analyze the serum levels of 25(OH)D in different groups.Multiple linear regressions were utilized to analyze the determinants of the maternal HBV DNA level at delivery.Univariate and multivariate logistic regression analyses were employed to explore the association of targeted antiviral effects with various characteristics at baseline and delivery.RESULTS A total of 38 pregnant women in Mianyang City at high risk for MTCT of HBV were enrolled in the study.The MTCT rate was 0%.No mother achieved hepatitis B e antigen or hepatitis B surface antigen(HBsAg)clearance at delivery.Twenty-three(60.5%)participants were full responders,and 15(39.5%)participants were partial responders according to antiviral efficacy.The present study showed that a high percentage(76.3%)of pregnant women with high HBV viral loads had deficient(<20 ng/mL)or insufficient(≥20 but<31 ng/mL)VD levels.Serum 25(OH)D levels in partial responders appeared to be significantly lower than those in full responders both at baseline(25.44±9.42 vs 17.66±5.34 ng/mL,P=0.006)and delivery(26.76±8.59 vs 21.24±6.88 ng/mL,P=0.044).Serum 25(OH)D levels were negatively correlated with maternal HBV DNA levels[log(10)IU/mL]at delivery after TDF therapy(r=-0.345,P=0.034).In a multiple linear regression analysis,maternal HBV DNA levels were associated with baseline maternal serum 25(OH)D levels(P<0.0001,β=-0.446),BMI(P=0.03,β=-0.245),baseline maternal log10 HBsAg levels(P=0.05,β=0.285)and cholesterol levels at delivery(P=0.015,β=0.341).Multivariate logistic regression analysis showed that baseline serum 25(OH)D levels(OR=1.23,95%CI:1.04-1.44),maternal VDR Cdx2 TT(OR=0.09,95%CI:0.01-0.88)and cholesterol levels at delivery(OR=0.39,95%CI:0.17-0.87)were associated with targeted antiviral effects(maternal HBV DNA levels<2×10^(5) at delivery).CONCLUSION Maternal VD levels and VDR SNPs may be associated with the efficacy of antiviral therapy in pregnant women with high HBV viral loads.Future studies to evaluate the therapeutic value of VD and its analogs in reducing the MTCT of HBV may be justified. 展开更多

Invasive fungal infections are a major challenging problem in the management of febrile neutropenia (FN) in patients with hematologic malignancies. Liposomal amphotericin B (L-AmB) or micafungin (MCFG) has been widely used as a first-line empirical antifungal therapy for suspected fungal infection in such patients. However, there are several issues in patients receiving these agents: drug related toxicities for L-AmB and breakthrough fungal infections for MCFG. In order to make the best use of these 2 agents, we conducted a prospective study of sequential therapy from MCFG to L-AmB, and evaluated the efficacy and safety of this strategy in FN patients with hematologic malignancies. A total of 18 patients were enrolled, and 11 patients who fulfilled the protocol defined criteria were evaluated. Underlying diseases consisted of acute leukemia (n = 9), non-Hodgkin lymphoma (n = 1), and myelodysplastic syndrome (n = 1). Treatment success was achieved in 8 patients (72.7%). Drug-related adverse events occurred in 8 patients (72.7%). All of those adverse events except one case were below grade 2. Three patients required discontinuation of L-AmB. Although our empirical antifungal sequential therapy seems to be encouraging for antibiotics-refractory FN in patients with hematologic malignancies, further investigation in large-scale studies is warranted. 展开更多
