Care strategies for patients with severe drug-induced hepatitis

Objective: The aim of this study is to analyse the clinical characteristics of 32 patients with severe drug-induced hepatitis, reinforce the practice of unique nursing and holistic nursing, improve the therapeutic effect, reduce the patients’ mortality, and increase their quality of life. Methods: We give patients individualized dietary guidance, medication nursing, and psychological care according to the characteristics of severe hepatitis and its complications, using com- prehensive medical treatment and combined signs of Traditional Chinese Medicine. Results: Overall, 22 (68.8%) out of 32 cases were improved, 8 (25.0%) cases died, and 2 (6.2%) cases were discharged of free will. In addition, the average hospital stay was 28.75 days. Conclusion: This study indicates that dietary guidance for the patients with severe drug-induced hepatitis varies with the individual. The result embodies the concept of Traditional Chinese Medicine that different treatment for the same disease and different diet for the same disease. Special nursing enriches the connotation of holistic nursing. Both of them are vital for improving the survival rate and promoting rehabilitation of patients with severe drug-induced hepatitis.

A rare cause of drug-induced hepatitis in an immunocompromised patient and the role of glutathione

The Food and Drug Administration (FDA) has issued a warning on numerous herbal drugs, including many popular products at General Nutrition Centers (GNC), regarding unstudied hepatotoxicity. There have been recent reports of GNC products such as hydroxycut and herbalife, causing drug-induced hepatitis. Herbal medications are over-the-counter products and are not investigated thoroughly by the FDA. Given that the mostcommon outpatient laboratory abnormality is elevated liver transaminases, a sign of hepatocellular toxicity; it is not surprising that some of these products end up causing hepatic dysfunction, especially when taken in large volume. There are numerous herbal supplements that are hepatotoxic, however, these medications have a much more significant effect in human immunodeficiency virus (HIV)/ acquired immune deficiency syndrome patients, which is secondary to depleted glutathione. We present a rare case of drug induced hepatitis secondary to herbal medications used to treat HIV and elucidate the role of glutathione depletion in immunocompromised patients.

Baseline HBV Load Increases the Risk of Anti-tuberculous Drug-induced Hepatitis Flares in Patients with Tuberculosis

Hepatitis associated anti-tuberculous treatment（HATT） has been a main obstacle in managing patients co-infected with Mycobacterium tuberculosis and hepatitis B virus（HBV）. Therefore, we evaluated the factors related to the severity of adverse effects during HATT, especially those associated with liver failure. A retrospective study was carried out at Tongji Hospital from 2007 to 2012. Increases in serum transaminase levels of 〉3, 5, and 10 times the upper limit of normal（ULN） were used to define liver damage as mild, moderate, and severe, respectively. Patients with elevated total bilirubin（TBil） levels that were more than 10 times the ULN（〉171 μmol/L） with or without decreased（〈40%） prothrombin activity（PTA） were diagnosed with liver failure. A cohort of 87 patients was analyzed. The incidence of liver damage and liver failure was 59.8%（n=52） and 25.3%（n=22）, respectively. The following variables were correlated with the severity of hepatotoxicity： albumin（ALB） levels, PTA, platelet counts（PLT）, and the use of antiretroviral therapies（P〈0.05）. Hypo-proteinemia and antiretroviral therapy were significantly associated with liver failure, and high viral loads were a significant risk factor with an odds ratio（OR） of 2.066. Judicious follow-up of clinical conditions, liver function tests, and coagulation function, especially in patients with high HBV loads and hypoalbuminemia is recommended. It may be advisable to reconsider the use of antiviral drugs failure during the course of anti-tuberculous treatment of HBV infection patients to avoid the occurrence of furious liver failure.

Blood coagulation factors and platelet response to drug-induced hepatitis and hepatosis in rats

Background:Knowing the variability of blood coagulation responses to liver damage of different origins can provide a key to curing liver tissues or to mitigating treatment side effects.The aim of the present work was to compare the changes in the main components of hemostasis under experimental drug-induced hepatosis and hepatitis in rats.Methods:We modeled diclofenac-induced hepatitis and tetracycline-induced hepa-tosis.Hemostasis response was gauged by measuring fibrinogen,factor X,protein C(PC),and prothrombin in plasma.The decarboxylated form of prothrombin was de-tected by measuring prothrombin index and ecamulin index.Platelet reactivity was studied using aggregometry.Results:Both hepatitis and hepatosis decreased the synthesis of fibrinogen,factor X,and prothrombin.However,protein carboxylation was not disrupted in hepatosis but was much impaired in hepatitis.PC decreased in both models as a consequence of its consumption possibly during inflammatory response.Platelet aggregation rate was lower in hepatosis but higher in hepatitis.Conclusions:Our findings imply the need for a thorough monitoring of the hemostasis system in liver diseases to avoid possible thrombotic complications.Its state indicates the disorder's rate and character.

Carbimazole Drug-Induced Hepatitis during Treatment of Graves’ Disease: About Four Cases at Dakar Teaching Hospital

Introduction: Mostly reported common side effects of carbimazole are cutaneous allergies and severe agranulocytosis. However, hepatotoxicity is rarely described. Thus, we report four observations of carbimazole drug-induced hepatitis during the treatment of Graves’ disease, which imputability is likely and probably an immuno-allergic mechanism. Observations: They were four women whose average age was 43 years, with extreme ages of 32 and 54. Patients were monitored and treated with carbimazole in doses contained between 40 mg and 60 mg per day. Clinical manifestations of liver injury were mainly dominated by cholestatic jaundice, found in 100% of our patients. A painful sensitivity of the right hypochondrium was concomitant with jaundice for two patients. The jaundice time to onset after the beginning of treatment with carbimazole varies between 1 month and 6 months. They all had acute hepatitis. The biological assays used to determine the type of liver injury showed, in all cases, a mixed, cholestatic and cytolytic hepatitis. Therapeutically, in all patients, carbimazole was stopped as soon as the suspicion of its incrimination in the occurrence of liver damage was set up. They all had a substitution of carbimazole with benzylthiouracil. Evolution was favorable for all patients, after therapeutic substitution. It was marked by disappearance of jaundice and normalization of the liver biological parameters within a maximum delay of two months after stopping carbimazole use. Conclusion: Treatment with synthetic antithyroid drugs, particularly carbimazole that is most widely used in our regions, requires clinical and biological monitoring. This surveillance, which is often difficult in Africa because of the limited economic resources, can lead to the occurrence of side effects such as potentially serious drug-induced hepatitis, but which has been favorable in our observations.

A Drug-induced Hepatitis Patient with a Manifestation of Liver Occupying Lesions on Ultrasound B:Case Report and Literature Review

Drug-induced liver injury(DILI)is defined as injury to the liver caused by exposure to a drug or some drugs.The number of cases suffering from DILI has been increased.There are few clinical features specifically associated with DILI.The recognition and diagnosis of DILI is difficult.In this report,we have described a DILI case caused by herbal remedies.

Current status of drug therapy for chronic hepatitis B

In this editorial,we comment on the article by Meng et al.Chronic hepatitis B(CHB)is a significant global health problem,particularly in developing countries.Hepatitis B virus(HBV)infection is one of the most important risk factors for cirrhosis and hepatocellular carcinoma.Prevention and treatment of HBV are key measures to reduce complications.At present,drug therapy can effectively control virus replication and slow disease progression,but completely eliminating the virus remains a challenge.Anti-HBV treatment is a long-term process,and there are many kinds of antiviral drugs with different mechanisms of action,it is essential to evaluate the safety and efficacy of these drugs to reduce side effects and improve patients’compliance.We will summarize the current status of CHB drug treatment,hoping to provide a reference for the selection of clinical antiviral drugs.

Gut microbiota shifts in hepatitis B-related portal hypertension after transjugular intrahepatic portosystemic shunt:Mechanistic and clinical implications

In this article,we provide commentary on the recent article by Zhao et al.We focus on the shifts in the gut microbiota of patients with hepatitis B virus(HBV)-associated cirrhosis/portal hypertension(PH)following transjugular intrahepatic portosystemic shunt(TIPS)and the implications for understanding the mechanisms,diagnosis,and treatment.By comparing the gut microbiota composition and dynamic changes before and after TIPS in patients with and without hepatic encephalopathy,the authors found an increase in non-probiotic bacteria in those who developed hepatic encephalopathy post-TIPS,with Morganella species present only in the hepatic encephalopathy group.The gut microbiota changes post-TIPS among patients without the occurrence of hepatic encephalopathy suggest potential therapeutic benefits through prophylactic microbiome therapies.Furthermore,the specific gut microbiota alterations may hold promise to predict the risk of hepatic encephalopathy in individuals undergoing TIPS for HBVrelated PH.Despite these promising findings,future studies are needed to address limitations,including a small sample size,a relatively short evaluation period for gut microbiota alterations,the absence of data on dynamic alterations in gut microbiota post-TIPS and their correlation with blood ammonia levels,and the lack of validation in animal models.In conclusion,Zhao et al's study has shed new light on the link of gut microbiota with post-TIPS hepatic encephalopathy,potentially through the intricate gut-liver axis,and has important clinical implications for improving the management of patients with HBV-related PH.

Antiviral therapy for hepatitis B virus infection is beneficial for the prognosis hepatocellular carcinoma

In this editorial,we comment on the article by Mu et al,published in the recent issue of the World Journal of Gastrointestinal Oncology.We pay special attention to the immune tolerance mechanism caused by hepatitis B virus(HBV)infection,the pathogenesis of hepatocellular carcinoma(HCC),and the role of antiviral therapy in treating HCC related to HBV infection.HBV infection leads to systemic innate immune tolerance by directly inhibiting pattern recognition receptor recognition and antiviral signaling pathways,as well as by inhibiting the immune functions of macrophages,natural killer cells and dendritic cells.In addition,HBV leads to an immunosuppressive cascade by expressing inhibitory molecules to induce exhaustion of HBV-specific cluster of differentiation 8+T cells,ultimately leading to long-term viral infection.The loss of immune cell function caused by HBV infection ultimately leads to HCC.Long-term antiviral therapy can improve the prognosis of patients with HCC and prevent tumor recurrence and metastasis.

Rising incidence of acute hepatitis A among adults and clinical characteristics in a tertiary care center of Pakistan

BACKGROUND For decades,hepatitis A virus(HAV)has been a leading cause of acute hepatitis among children and was less prevalent among adults.However,recently a paradigm shift has been observed in the epidemiology of HAV,as evident by cases of acute hepatitis due to HAV among adults.AIM To estimate frequency of HAV in acute viral hepatitis and compare characteristics in HAV and hepatitis E virus(HEV)infection.METHODS This was a trend analysis conducted at Aga Khan University Hospital Karachi(Sindh,Pakistan)from February 2024 to May 2024.Individuals aged 18 years and older diagnosed with acute viral hepatitis attributed to hepatotropic viruses in 2024 were reviewed.To compare the trend patients admitted with acute hepatitis during 2019-2023 were also reviewed.Data regarding clinical and laboratory parameters were recorded.The yearly trend of acute hepatitis due to HAV and HEV was analyzed,and comparative analysis was done between HAV and HEV cases among adults.RESULTS A total of 396 patients were found to have acute hepatitis during our study duration.HAV was diagnosed in 234 patients(59%)while 157 patients(39.6%)were found to have acute HEV infection.Additionally,acute hepatitis B virus infection was identified in 3 patients(0.7%),whereas acute hepatitis C virus infection was found in 2(0.5%)cases of acute hepatitis.Yearly trends showed increasing occurrence of HAV infection among adults over last 5 years.The patients with acute HAV were younger than patients with HEV(28 years±8 years vs 30 years±8 years;P<0.01).Higher levels of total bilirubin were seen in HEV infection,while higher levels of alanine transaminase were seen in HAV infection.However,a higher proportion of acute liver failure(ALF),coagulopathy,and mortality were observed in HEV.CONCLUSION An increase in acute hepatitis A cases among adults shows less severity than hepatitis E,highlighting the need for better sanitation,hygiene,and adult hepatitis A vaccination programs.

Exploring the performance of large language models on hepatitis B infection-related questions:A comparative study

BACKGROUND Patients with hepatitis B virus(HBV)infection require chronic and personalized care to improve outcomes.Large language models(LLMs)can potentially provide medical information for patients.AIM To examine the performance of three LLMs,ChatGPT-3.5,ChatGPT-4.0,and Google Gemini,in answering HBV-related questions.METHODS LLMs’responses to HBV-related questions were independently graded by two medical professionals using a four-point accuracy scale,and disagreements were resolved by a third reviewer.Each question was run three times using three LLMs.Readability was assessed via the Gunning Fog index and Flesch-Kincaid grade level.RESULTS Overall,all three LLM chatbots achieved high average accuracy scores for subjective questions(ChatGPT-3.5:3.50;ChatGPT-4.0:3.69;Google Gemini:3.53,out of a maximum score of 4).With respect to objective questions,ChatGPT-4.0 achieved an 80.8%accuracy rate,compared with 62.9%for ChatGPT-3.5 and 73.1%for Google Gemini.Across the six domains,ChatGPT-4.0 performed better in terms of diagnosis,whereas Google Gemini demonstrated excellent clinical manifestations.Notably,in the readability analysis,the mean Gunning Fog index and Flesch-Kincaid grade level scores of the three LLM chatbots were significantly higher than the standard level eight,far exceeding the reading level of the normal population.CONCLUSION Our results highlight the potential of LLMs,especially ChatGPT-4.0,for delivering responses to HBV-related questions.LLMs may be an adjunctive informational tool for patients and physicians to improve outcomes.Nevertheless,current LLMs should not replace personalized treatment recommendations from physicians in the management of HBV infection.

C-X-C chemokine receptor type 5+CD8+T cells as immune regulators in hepatitis Be antigen-positive chronic hepatitis B under interferonalpha treatment

BACKGROUND C-X-C chemokine receptor type 5(CXCR5)+CD8+T cells represent a unique immune subset with dual roles,functioning as cytotoxic cells in persistent viral infections while promoting B cell responses.Despite their importance,the specific role of CXCR5+CD8+T cells in chronic hepatitis B(CHB),particularly during interferon-alpha(IFN-α)treatment,is not fully understood.This study aims to elucidate the relationship between CXCR5+CD8+T cells and sustained serologic response(SR)in patients undergoing 48 weeks of pegylated IFN-α(peg-IFN-α)treatment for CHB.AIM To elucidate the relationship between CXCR5+CD8+T cells and sustained SR in patients undergoing 48 weeks of peg-IFN-αtreatment for CHB.METHODS This study enrolled 60 patients with hepatitis Be antigen(HBeAg)-positive CHB undergoing 48 weeks of peg-IFN-αtreatment.Participants were assessed for eligibility based on criteria such as persistent HBsAg-positive status for at least six months,HBeAb-negative,hepatitis B virus DNA levels exceeding 2×104 copies/mL,and alanine aminotransferase(ALT)levels between 2 and 10 times the upper limit of normal.Blood samples were collected at baseline and at weeks 12,24,48,and a 24-week treatment-free follow-up(week 72)to measure serum interleukin(IL)-21 concentration via ELISA and to analyze CXCR5 and programmed death-ligand 1(PD-L1)expression on CD8+T cells by flow cytometry,CXCR5 is a chemokine receptor that directs immune cells to specific tissues,while PD-L1 is a protein that regulates immune responses by inhibiting T cell activity.RESULTS Patients with CHB exhibited significantly lower levels of circulating CXCR5+CD8+T cells compared to healthy controls(P<0.01).Notably,CXCR5+CD8+T cells were prominently expressed in patients who achieved sustained SR compared to non-SR(NSR).A significant correlation was observed between CXCR5 and PD-L1 expression(r=-0.189,P=0.002).However,there was no significant correlation between serum IL-21 levels and CXCR5+CD8+lymphocytes(r=-0.03,P=0.625)or serum ALT levels(r=0.026,P=0.678).CONCLUSION The enhanced expression of CXCR5+CD8+T cells in patients achieving HBeAg seroconversion during IFN-αtreatment suggests that these cells play a crucial role in antiviral immune responses against hepatitis B.This study highlights the potential of CXCR5+CD8+T cells as immune regulators in CHB,which may inform future therapeutic strategies to optimize antiviral treatments.

Trends of alkaline phosphatase to prealbumin ratio in patients with hepatitis B linked to hepatocellular carcinoma development

BACKGROUND Chronic hepatitis B often progresses silently toward hepatocellular carcinoma(HCC),a leading cause of mortality worldwide.Early detection of HCC is crucial,yet challenging.AIM To investigate the role of dynamic changes in alkaline phosphatase to prealbumin ratio(APR)in hepatitis B progression to HCC.METHODS Data from 4843 patients with hepatitis B(January 2015 to January 2024)were analyzed.HCC incidence rates in males and females were compared using the log-rank test.Data were evaluated using Kaplan–Meier analysis.The Linear Mixed-Effects Model was applied to track the fluctuation of APR levels over time.Furthermore,Joint Modeling of Longitudinal and Survival data was employed to investigate the temporal relationship between APR and HCC risk.RESULTS The incidence of HCC was higher in males.To ensure the model’s normality assumption,this study applied a logarithmic transformation to APR,yielding ratio.Ratio levels were higher in females(t=5.26,P<0.01).A 1-unit increase in ratio correlated with a 2.005-fold higher risk of HCC in males(95%CI:1.653-2.431)and a 2.273-fold higher risk in females(95%CI:1.620-3.190).CONCLUSION Males are more prone to HCC,while females have higher APR levels.Despite no baseline APR link,rising APR indicates a higher HCC risk.

Drug-induced autoimmune hepatitis:A minireview

Drug-induced autoimmune hepatitis(DIAIH)is a specific phenotype of druginduced liver injury that may lead to the devastating outcome of acute liver failure requiring liver transplantation.Drugs implicated in DIAIH include antimicrobials such as nitrofurantoin and minocycline,non-steroidal anti-inflammatory drugs,statins as well as anti-tumor necrosis agents.The clinical features of druginduced liver injury are indistinguishable from idiopathic autoimmune hepatitis(AIH)as both may have positive AIH-related autoantibodies,elevated immunoglobulin G,as well as similar histopathological findings.In patients who show no clinical improvement,or there is progressive liver injury despite cessation of the suspected drug,a liver biopsy should be considered,whereby the presence of advance fibrosis on histology favors the diagnosis of idiopathic AIH.Empirical treatment with corticosteroids may be required in patients with non-resolving liver injury.A typical clinical scenario supportive of DIAIH includes a history of drug exposure with spontaneous resolution of liver injury after drug withdrawal and the absence of relapse after rapid steroid taper.In this article we report two cases of DIAIH secondary to Sorafenib and Atorvastatin along with a review of currently available literature.Early identification and treatment often lead to a favorable outcome in DIAIH.

CD4+Foxp3+CD25+/-Tregs characterize liver tissue specimens of patients suffering from drug-induced autoimmune hepatitis:A clinical-pathological study

Background: The diagnosis of drug-induced autoimmune hepatitis(DIAIH) and its differentiation from idiopathic autoimmune hepatitis(AIH) is challenging. This study aimed to differentiate DIAIH from AIH by comparing the biochemical changes, histological features, and frequencies of CD4~+Foxp3~+CD25+/-regulatory T cells(Tregs) in liver tissues or peripheral blood lymphocytes.Methods: A total of 15 DIAIH patients and 24 AIH patients who underwent liver biopsies at initial presentation were enrolled in this study. The liver histological changes were assessed by HE staining. The phenotypic recognition and distribution of CD4~+Foxp3~+CD25+/-Tregs in liver tissues were evaluated by single/double immunostains in serial sections. The CD4~+Foxp3~+CD25+/-Tregs in peripheral blood were analyzed by flow cytometry.Results: The median values of ALT and AST were 404.50 U/L and 454.10 U/L in DIAIH patients and309.50 U/L and 315.00 U/L in AIH patients, respectively. More importantly, for the first time we found that patients with DIAIH had higher levels of serum ALT and AST, more severe degree of lobular inflammation,higher frequencies of zone 3 necrosis and higher number of lobular CD4~+Foxp3~+CD25~-Tregs compared with AIH(P < 0.05). Furthermore, there were positive correlations in DIAIH between the degree of lobular inflammation and either the AST/ALT level or the number of lobular CD4~+Foxp3~+CD25~-Tregs(P < 0.05).However, the frequency of peripheral blood CD4~+Foxp3~+CD25+/-Tregs were not significantly different between DIAIH and AIH.Conclusions: The differences of ALT, AST and the number of lobular CD4~+Foxp3~+CD25~-Tregs between patients with DIAIH and those with AIH are clinically helpful in differentiating these two diseases in their early stage.

Hepatitis C virus cures after direct acting antiviral-related drug-induced liver injury: Case report

The United States Food and Drug Administration recently warned that the direct acting antiviral(DAA) combination hepatitis C virus(HCV) treatment of Paritaprevir, Ombitasvir, Dasabuvir, Ritonavir, and Ribavirin(PODr + R) can cause severe liver injury in patients with advanced liver disease. Drug induced liver injury was observed in a small number of patients with decompensated cirrhosis treated with other DAAs, but has not been reported in patients with compensated cirrhosis. We report a case of a 74-year-old woman with chronic HCV and Child-Pugh class A cirrhosis(compensated cirrhosis) treated with PODr + R. The patient presented on day 14 of PODr + R therapy with jaundice and new-onset ascites. Her total bilirubin level increased to 23 mg/dL and international normalized ratio rose to 1.65, while aminotransferase levels remained relatively stable. Hepatitis C treatment was discontinued on day 24 and she gradually recovered. Follow-up testing showed that she achieved a sustained virologic response. In conclusion, hepatic decompensation developed within two weeks of starting treatment withPODr + R in a patient with Child-Pugh class A cirrhosis and was characterized by jaundice and ascites with stable aminotransferase levels. Careful monitoring is warranted in patients with HCV-related cirrhosis treated with PODr + R.

Current perspectives of viral hepatitis

Viral hepatitis represents a major danger to public health,and is a globally leading cause of death.The five liver-specific viruses:Hepatitis A virus,hepatitis B virus,hepatitis C virus,hepatitis D virus,and hepatitis E virus,each have their own unique epidemiology,structural biology,transmission,endemic patterns,risk of liver complications,and response to antiviral therapies.There remain few options for treatment,in spite of the increasing prevalence of viral-hepatitiscaused liver disease.Furthermore,chronic viral hepatitis is a leading worldwide cause of both liver-related morbidity and mortality,even though effective treatments are available that could reduce or prevent most patients’complications.In 2016,the World Health Organization released its plan to eliminate viral hepatitis as a public health threat by the year 2030,along with a discussion of current gaps and prospects for both regional and global eradication of viral hepatitis.Today,treatment is sufficiently able to prevent the disease from reaching advanced phases.However,future therapies must be extremely safe,and should ideally limit the period of treatment necessary.A better understanding of pathogenesis will prove beneficial in the development of potential treatment strategies targeting infections by viral hepatitis.This review aims to summarize the current state of knowledge on each type of viral hepatitis,together with major innovations.

Alterations in the gut microbiome after transjugular intrahepatic portosystemic shunt in patients with hepatitis B virus-related portal hypertension

BACKGROUND Gut microbiota(GM)affects the progression and response to treatment in liver diseases.The GM composition is diverse and associated with different etiologies of liver diseases.Notably,alterations in GM alterations are observed in patients with portal hypertension(PH)secondary to cirrhosis,with hepatitis B virus(HBV)infection being a major cause of cirrhosis in China.Thus,understanding the role of GM alterations in patients with HBV infection-related PH is essential.AIM To evaluate GM alterations in patients with HBV-related PH after transjugular intrahepatic portosystemic shunt(TIPS)placement.METHODS This was a prospective,observational clinical study.There were 30 patients(with a 100%technical success rate)recruited in the present study.Patients with esophagogastric variceal bleeding due to HBV infection-associated PH who underwent TIPS were enrolled.Stool samples were obtained before and one month after TIPS treatment,and GM was analyzed using 16S ribosomal RNA amplicon sequencing.RESULTS One month after TIPS placement,8 patients developed hepatic encephalopathy(HE)and were assigned to the HE group;the other 22 patients were assigned to the non-HE group.There was no substantial disparity in the abundance of GM at the phylum level between the two groups,regardless of TIPS treatment(all,P>0.05).However,following TIPS placement,the following results were observed:(1)The abundance of Haemophilus and Eggerthella increased,whereas that of Anaerostipes,Dialister,Butyricicoccus,and Oscillospira declined in the HE group;(2)The richness of Eggerthella,Streptococcus,and Bilophila increased,whereas that of Roseburia and Ruminococcus decreased in the non-HE group;and(3)Members from the pathogenic genus Morganella appeared in the HE group but not in the non-HE group.CONCLUSION Intestinal microbiota-related synergism may predict the risk of HE following TIPS placement in patients with HBVrelated PH.Prophylactic microbiome therapies may be useful for preventing and treating HE after TIPS placement.

Risk of hepatitis B virus reactivation in oncological patients treated with tyrosine kinase inhibitors:A case report and literature analysis

Hepatitis B virus(HBV)reactivation(HBVr)represents a severe and potentially life-threatening condition,and preventive measures are available through blood test screening or prophylactic therapy administration.The assessment of HBVr traditionally considers factors such as HBV profile,including hepatitis B surface antigen(HBsAg)and antibody to hepatitis B core antigen,along with type of medication(chemotherapy;immunomodulants).Nevertheless,consideration of possible patient’s underlying tumor and the specific malignancy type(solid or hematologic)plays a crucial role and needs to be assessed for decision-making process.

Perioperative remedial antiviral therapy in hepatitis B virus-related hepatocellular carcinoma resection:How to achieve a better outcome

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.
