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.

Hepatitis B core-related antigen as a promising serological marker for monitoring hepatitis B virus cure

Hepatitis B virus(HBV)infection is a global health concern.The current sequen-tial endpoints for the treatment of HBV infection include viral suppression,hepatitis B e antigen(HBeAg)seroconversion,functional cure,and covalently closed circular DNA(cccDNA)clearance.Serum hepatitis B core-related antigen(HBcrAg)is an emerging HBV marker comprising three components:HBeAg,hepatitis B core antigen,and p22cr.It responds well to the transcriptional activity of cccDNA in the patient's liver and is a promising alternative marker for serolo-gical testing.There is a strong correlation,and a decrease in its level corresponds to sustained viral suppression.In patients with chronic hepatitis B(CHB),serum HBcrAg levels are good predictors of HBeAg seroconversion(both spontaneous and after antiviral therapy),particularly in HBeAg-positive patients.Both low baseline HBcrAg levels and decreasing levels early in antiviral therapy favored HBsAg seroconversion,which may serve as a good surrogate option for treatment endpoints.In this review,we summarize the role of serum HBcrAg in the treat-ment of CHB.Therefore,long-term continuous monitoring of serum HBcrAg levels contributes to the clinical management of patients with CHB and optimizes the choice of treatment regimen,making it a promising marker for monitoring HBV cure.

Timing of post-vaccination tests in infants born to mothers with chronic hepatitis B virus infection

Immunoprophylaxis is routinely recommended for infants born to mothers with hepatitis B virus(HBV)infection within the first 12-24 hours.Detection of he-patitis B surface antibody(HBsAb)resulting from hepatitis B immunoglobulin administered at birth may be perceived as a real vaccine response.This makes it difficult to detect HBV infection.For this reason,it is recommended that infants born to hepatitis B surface antigen positive mothers and who received immunop-rophylaxis at birth should have HBsAb testing when they are 9-15 months old.

Clinical features of abnormalα-fetoprotein in 15 patients with chronic viral hepatitis B after treatment with antiviral drugs

BACKGROUND Liver function of chronic hepatitis B(CHB)patients is essentially normal after treatment with antiviral drugs.In rare cases,persistently abnormally elevatedα-fetoprotein(AFP)is seen in CHB patients following long-term antiviral treatment.However,in the absence of imaging evidence of liver cancer,a reasonable expla-nation for this phenomenon is still lacking.AIM To explore the causes of abnormal AFP in patients with CHB who were not diag-nosed with liver cancer.METHODS From November 2019 to May 2023,15 patients with CHB after antiviral treatment and elevated AFP were selected.Clinical data and quality indicators related to laboratory testing,imaging data,and pathological data were obtained through inpatient medical records.RESULTS All patients had increased AFP and significantly elevated IgG.Cancer was excluded by imaging examination.Only four patients had elevated alanine ami-notransferase,10 had elevated aspartate aminotransferase,nine had elevated total bilirubin,and two had antinuclear antibodies.The liver biopsy and histopatho-logical examination indicated that 14 patients had rosette,moderate,or higher interfacial inflammation,lymphocyte infiltration,and severe hepatic fibers(11 cases),which was consistent with the pathological features of autoimmune hepa-titis(AIH).After 8-12 week of hormone therapy,the levels of AFP and IgG,and liver function returned to normal(P<0.05).CONCLUSION For patients with CHB and elevated AFP after antiviral treatment,autoimmune hepatitis should be considered.CHB with AIH is clinically insidious and difficult to detect,and prone to progression to cirrhosis.Liver puncture pathological examination should be performed when necessary to confirm diagnosis.

Hepatitis B virus infection and its treatment in Eastern Ethiopia

Hepatitis B virus(HBV)infection causes acute and chronic hepatitis,compensated and decompensated cirrhosis,and hepatocellular carcinoma worldwide.The actual status of HBV infection and its treatment in certain regions of Asian and African countries,including Ethiopia,has not been well-documented thus far.Antiviral therapy for HBV infection can prevent the progression of HBV-related liver diseases and decrease the HBV-related symptoms,such as abdominal symp-toms,fatigue,systemic symptoms and others.In Eastern Ethiopia,HBV-infected patients with cirrhosis were found to be positive for the HBV e antigen and to have a higher viral load than those without cirrhosis.Notably,54.4%of patients practiced khat chewing and 18.1%consumed excessive amounts of alcohol.Teno-fovir disoproxil fumarate effectively suppressed HBV DNA in those infected with HBV.It is important to elucidate the actual status of HBV infection in Eastern Ethiopia to eliminate HBV infection worldwide by 2030.HBV vaccination and the educational programs for Health Science students that provide practical strategies could help to reduce HBV infection in Eastern Ethiopia.

Prevalence of cardiometabolic co-morbidities in patients with vs persons without chronic hepatitis B: The FitLiver cohort study

BACKGROUND Chronic hepatitis B(CHB)affects>300 million people worldwide.The combi-nation of CHB and cardiometabolic co-morbidities increases the risk of liver-related morbidity and mortality.However,international guidelines for CHB treatment do not provide recommendations for follow-up examinations or treatment of patients with CHB and cardiometabolic comorbidities.In studies investigating cardiometabolic co-morbidity in patients with CHB,inconsistent findings have been observed,and both lower and higher prevalence of car-diometabolic co-morbidities compared to the general population have been re-ported.It is unclear whether patients with CHB living in Denmark have an increased prevalence of cardiometabolic co-morbidities.We examined patients with CHB and age-,sex-,body mass index(BMI)-,and country-of-birth matched comparison group.Defining cardiometabolic co-morbidity:Obesity(BMI>25 kg/m2/abnormal waist-to-hip ratio),metabolic dysfunction-associated steatotic liver disease(MASLD),hypercholesterolemia(total-cholesterol>5 mmol/L/statin use),hypertension(systolic≥135 mmHg/diastolic≥85 mmHg/antihypertensive medication)and type 2 diabetes(T2D)(2-hour oral glucose tolerance test glucose>11.1 mmol/L/HbA1c>48 mmol/mol/antidiabetic medication).Physical activity was evaluated using maximal oxygen consumption(VO2max),activity monitors,and a questionnaire.RESULTS We included 98 patients with CHB and 49 persons in the comparison group.The two groups were well-matched,showing no significant differences in age,sex,BMI,country-of-birth,education,or employment.Among patients with CHB,the following prevalence of cardiometabolic co-morbidity was found:77%were obese,45%had MASLD,38%had hypercholesterolemia,26%had hypertension,and 7%had T2D,which did not differ significantly from the comparison group,apart from lower prevalence of hemoglobin A1c(HbA1c)≥48 mmol/L or known T2D.Both groups had low VO2max of 27 mL/kg/minute in the patients with CHB and 30 mL/kg/minute in the comparison group,and the patients with CHB had a shorter self-assessed sitting time.CONCLUSION The patients with CHB and the comparison group were well-matched and had a similar prevalence of car-diometabolic comorbidities.Furthermore,both groups had low levels of physical fitness.

Evaluating the scope of human leukocyte antigen polymorphisms influencing hepatitis B virus-related liver cancer and cirrhosis through multi-clustering analysis

Hepatitis B virus remains a major cause of cirrhosis and hepatocellular carcinoma,with genetic polymorphisms and mutations influencing immune responses and disease progression.Nguyen et al present novel findings on specific human leukocyte antigen(HLA)alleles,including rs2856718 of HLA-DQ and rs3077 and rs9277535 of HLA-DP,which may predispose individuals to cirrhosis and liver cancer,based on multi-clustering analysis.Here,we discuss the feasibility of this approach and identify key areas for further investigation,aiming to offer insights for advancing clinical practice and research in liver disease and related cancers.

Hepatitis B virus infection and metabolic dysfunction associated steatotic liver disease:Rising pandemic with complex interaction

Due to sedentary lifestyle and rising prevalence of obesity,patients with general population and those who are infected with chronic hepatitis B are found to have metabolic dysfunction associated steatotic liver disease(MASLD).Both chronic hepatitis B virus(HBV)infection and MASLD can damage hepatocytes in their own way,but concomitant HBV-MASLD has its own clinical implications.Cherry on top is the presence of diabetes mellitus,hypertension or obesity which added more chances of unfavorable outcomes in these patients.In this article,we co-mment on the article by Wang et al published in the recent issue.This article provides a comprehensive overview of the complex interaction between HBV-MASLD,HBV alone and MASLD alone patients.We discuss key findings from recent studies,including the promising outcomes observed in patients with concurrent HBV and MASLD,warrants further research.The insights presented here offer renewed understanding of this complex interaction.

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.

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.

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.

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.

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.
