She went on to develop epigastric pain, darkening of urine and jaundice, with no resolution of prior symptoms. Physical and Laboratory tests confirmed the primary diagnosis of infectious mononucleosis, however, prior history of treatment with multiple drugs led to a diagnosis of DILI as a complication. Appropriate treatment with I.V. antibiotics, hepatoprotective agents, steroids as well as discontinuation of all potential hepatotoxic agents showed significant improvement in patients’ symptoms and overall condition.展开更多

The fi rst step in diagnosis is a suspicion of DILI based on careful consideration of recent comprehensive reports on the disease. There are some situations in which the suspicion of DILI is particularly strong. Exclusion of other possible etiologies according to the pattern of liver injury is essential for the diagnosis. In patients with suspected DILI,diagnostic scales,such as the Councils for International Organizations of Medical Sciences/ Roussel Uclaf Causality Assessment Method (CIOMS/ RUCAM) scale,may be helpful for the fi nal diagnosis. Early management of DILI involves prompt withdrawal of the drug suspected of being responsible,according to serum levels of alanine aminotransferase (ALT),alkaline phosphatase (ALP),and total bilirubin (T-Bil). However,as DILI patients may show resolution of liver injury without discontinuation of the drug,it should be carefully evaluated whether the suspected drug should be discontinued immediately with adequate consideration of the importance of the medication.展开更多

Risk factors for drug-induced liver injury include concomitant hepatic diseases, age and genetic polymorphisms of CYP. However, some susceptibility can today be predicted before drug administration, working on the common substrate, by phenotyping and genotyping studies and by taking in consideration patients' health status. Physicians should always think of this adverse effect in the absence of other clear hepatic disease. Ethical and legal problems towards operators in the health care system are always matters to consider.展开更多

By investigating the current state of the art, the latest scientific findings, controversies, and guidelines, this review will attempt to answer the question: Do we know everything? Since the first descriptions of hepatotoxicity over 70 years ago, more than 1000 drugs have been identified to date, however, much of our knowledge of diagnostic and pathophysiologic principles remains unchanged. Clinically ranging from asymptomatic transaminitis and acute or chronic hepatitis, to acute liver failure, DILI remains a leading causes of emergent liver transplant. The consumption of unregulated herbal and dietary supplements has introduced new challenges in epidemiological assessment and clinician management. As such, numerous registries have been created, including the United States Drug-Induced Liver Injury Network, to further our understanding of all aspects of DILI. The launch of Liver Tox and other online hepatotoxicity resources has increased our awareness of DILI. In 2013, the first guidelines for the diagnosis and management of DILI, were offered by the Practice Parameters Committee of the American College of Gastroenterology, and along with the identification of risk factors and predictors of injury, novel mechanisms of injury, refined causality assessment tools, and targeted treatment options have come to define the current state of the art, however, gaps in our knowledge still undoubtedly remain.展开更多

DILI can be clinically divided into three phenotypes: hepatocytic, cholestatic and mixed. Although the clinical manifestations of DILI are variable and the pathogenesis complicated, recent insights using improved preclinical models, have allowed a better understanding of the mechanisms that trigger liver damage. In this review, we will discuss the pathophysiological mechanisms underlying DILI. The toxicity of the drug eventually induces hepatocellular damage through multiple molecular pathways, including direct hepatic toxicity and innate and adaptive immune responses. Drugs or their metabolites, such as the common analgesic, acetaminophen, can cause direct hepatic toxicity through accumulation of reactive oxygen species and mitochondrial dysfunction. The innate and adaptive immune responses play also a very important role in the occurrence of idiosyncratic DILI. Furthermore, we examine common forms of hepatocyte death and their association with the activation of specific signaling pathways.展开更多

Methods:Clean male SD rats were selected as experimental animals and randomly divided into normal group,model group,PDTC group and AG490 group. Animal model of anti-tuberculosis drug-induced liver injury was established by intragastric administration isoniazid + rifampicin. PDTC group received intraperitoneal injection of PDTC,and AG490 group received intraperitoneal injection of AG490. Twenty-eight days after intervention,the rats were executed,and the liver injury indexes,inflammation indexes and oxidative stress indexes in serum as well as JAK2/STAT3 expression,liver injury indexes,inflammation indexes and oxidative stress indexes in liver tissue were determined. Results:p-JAK2,p-STAT3,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA expression in liver tissue as well as TBIL,ALT,AST,γ-GT,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA levels in serum of model group were significantly higher than those of normal group while p-JAK2,p-STAT3,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA expression in liver tissu as well as TBIL,ALT,AST,γ-GT,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA levels in serum of PDTC group and AG490 group were significantly lower than those of model group. Conclusions:PDTC can inhibit the inflammation and oxidative stress mediated by JAK2/STAT3 signaling pathway to alleviate the anti-tuberculosis drug-induced liver injury.展开更多

Demographic data(sex and age),biochemical indexes(total protein,albumin,alanine aminotransferase,aspartate aminotransferase,total bilirubin,direct bilirubin,indirect bilirubin,alkaline phosphatase,and gamma glutamyltransferase),immunological indexes [immunoglobulin(Ig) A,Ig G,Ig M,antinuclear antibody,anti-smooth muscle antibody,anti-mitochondrial antibody,and anti-mitochondrial antibodies] and pathological findings were compared in PBC patients,untyped DILI patients and patients with different types of DILI(hepatocellular type,cholestatic type and mixed type). RESULTS There were significant differences in age and gender distribution between DILI patients and PBC patients. Biochemical indexes(except ALB),immunological indexes,positive rates of autoantibodies(except SMA),and number of cases of patients with different ANA titers(except the group at a titer of 1:10000)significantly differed between DILI patients and PBC patients. Biochemical indexes,immunological indexes,and positive rate of autoantibodies were not quite similar in different types of DILI. PBC was histologically characterized mainly by edematous degeneration of hepatocytes(n = 30),inflammatory cell infiltration around bile ducts(n = 29),and atypical hyperplasia of small bile ducts(n = 28). DILI manifested mainly as fatty degeneration of hepatocytes(n = 15) and spotty necrosis or loss of hepatocytes(n = 14).CONCLUSION Although DILI and PBC share some similar laboratory tests(biochemical and immunological indexes) and pathological findings,they also show some distinct characteristics,which are helpful to the differential diagnosis of the two diseases.展开更多

METHODS During a 6-mo inclusion period, consecutive IBD cases having a control visit at IBD center were included. Basic demographics, IBD phenotype and IBD treatment were recorded on entry. Aminotransferase(AT) activities of ALT, AST, ALP and gamma-glutamyl transpeptidase(GGT) were measured at baseline, 3 mo prior to study entry and prospectively every 3 mo for 1 year. Liver injury patterns were predefined as: Grade 1 in ALT 1-3 × upper limit of normal(ULN), grade 2 in ALT > 3 × ULN, hepatocellular injury in ALT > 2 × ULN, cholestatic injury in simultaneous GGT and ALP elevation > ULN.Persisting injury was reported when AT elevations were found on > 1 measurement. Risk factors for the patterns of liver injury were identified among demographic parameters, disease phenotype and IBD treatment in univariate and multivariate analysis. Finally, implications for the change in IBD management were evaluated in cases with persisting hepatocellular or cholestatic injury.RESULTS Two hundred and fifty-one patients were included having 917 ALT and 895 ALP and GGT measurements. Over one year, grade 1 injury was found in 66(26.3%), grade 2 in 5(2%) and hepatocellular injury in 16 patients(6.4%). Persisting hepatocellular injury was found in 4 cases. Cholestasis appeared in 11 cases(4.4%) and persisted throughout the entire study period in 1 case. In multivariate analysis, hepatocellular injury was associated with BMI(OR = 1.13, 1.02-1.26), liver steatosis(OR = 10.61, 2.22-50.7), IBD duration(1.07, 1.00-1.15) and solo infliximab(OR = 4.57, 1.33-15.7). Cholestatic liver injury was associated with prior intestinal resection(OR = 32.7, 3.18-335), higher CRP(OR = 1.04, 1.00-1.08) and solo azathioprine(OR = 10.27, 1.46-72.3). In one case with transient hepatocellular injury azathioprine dose was decreased. In 4 cases with persisting hepatocellular injury, fatty liver or alcohol were most likely causes and IBD treatment was pursued without change. In the case with persisting cholestatic injury, no signs of portal hypertension were identified and treatment with infliximab continued.CONCLUSION Liver injury was frequent, mostly transient and rarely changed management. Infliximab or azathioprine were confirmed as its risk factors indicating the need for regular AT monitoring.展开更多

In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the Peo- ple's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance.展开更多

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.展开更多

Critical understanding of various aspects of TB DILI is not only important to manage liver injury but may also prevent unnecessary discontinuation of antituberculosis treatment. The study is aimed to determine the frequency, types, severity and patterns of TB DILI. Study further evaluates various risk factors of TB DILI. Materials and Methods: This is a prospective cohort study of two seventy-eight patients with the diagnosis of tuberculosis, where patients were followed during tuberculosis treatment. TB DILI was defined in accordance to international DILI expert working group. Results: Out of two seventy eight-patients, ninety-five (34.14%) had TB DILI. The most common pattern of TB DILI was hepatocellular (63.15%) followed by mixed (23.15%) and Cholestatic (13.68%). Most of the patients had mild DILI (43.15%) followed by moderate (30.52%), severe (20.01%) and very severe (5.26%). Age > 35 years, concomitant hepatotoxic drugs, extrapulmonary TB and malnutrition are important risk factors for TB DILI. Conclusion: All patterns of TB DILI with varying severity were present. Age > 35 years, malnutrition, extrapulmonary TB and concomitant use of hepatotoxic drugs were risk factors for TB DILI.展开更多

The aim of this review was to analyze the suitability of the liver specific Council for International Organizations of Medical Sciences(CIOMS) scale as a standard tool for causality assessment in DILI and HILI cases. PubMed database was searched for the following terms: drug induced liver injury; herb induced liver injury; DILI causality assessment; and HILI causality assessment. The strength of the CIOMS lies in its potential as a standardized scale for DILI and HILI causality assessment. Other advantages include its liver specificity and its validation for hepatotoxicity with excellent sensitivity, specificity and predictive validity, based on cases with a positive reexposure test. This scale allows prospective collection of all relevant data required for a valid causality assessment. It does not require expert knowledge in hepatotoxicity and its results may subsequently be refined. Weaknesses of the CIOMS scale include the limited exclusion of alternative causes and qualitatively graded risk factors. In conclusion, CIOMS appears to be suitable as a standard scale for attending physicians, regulatory agencies, expert panels and other scientists to provide a standardized, reproducible causality assessment in suspected DILI and HILI cases, applicable primarily at all assessing levels involved. 2014 Baishideng Publishing Group Co., Limited.

文摘Drug-induced liver injury(DILI)is a major problem in the United States,commonly leading to hospital admission.Diagnosing DILI is difficult as it is a diagnosis of exclusion requiring a temporal relationship between drug exposure and liver injury and a thorough work up for other causes.In addition,DILI has a very variable clinical and histologic presentation that can mimic many different etiologies of liver disease.Objective scoring systems can assess the probability that a drug caused the liver injury but liver biopsy findings are not part of the criteria used in these systems.This review will address some of the recent updates to the scoring systems and the role of liver biopsy in the diagnosis of DILI.
文摘This editorial addresses the growing concern of herb-induced liver injury(HILI),focusing on a unique case of Skullcap-induced HILI report.This editorial underscore the significant mortality rate linked to Skullcap-induced HILI,emphasizing the importance of vigilant monitoring and intervention.As herbal supplement usage rises,collaboration among clinicians and researchers is crucial to comprehend and address the complexities of HILI,particularly those involving Skullcap.
文摘In this case, a young female presented with non-specific features such as fever, sore throat, headache and fatigue. She went on to develop epigastric pain, darkening of urine and jaundice, with no resolution of prior symptoms. Physical and Laboratory tests confirmed the primary diagnosis of infectious mononucleosis, however, prior history of treatment with multiple drugs led to a diagnosis of DILI as a complication. Appropriate treatment with I.V. antibiotics, hepatoprotective agents, steroids as well as discontinuation of all potential hepatotoxic agents showed significant improvement in patients’ symptoms and overall condition.
文摘The spectrum of drug-induced liver injury (DILI) is both diverse and complex. The fi rst step in diagnosis is a suspicion of DILI based on careful consideration of recent comprehensive reports on the disease. There are some situations in which the suspicion of DILI is particularly strong. Exclusion of other possible etiologies according to the pattern of liver injury is essential for the diagnosis. In patients with suspected DILI,diagnostic scales,such as the Councils for International Organizations of Medical Sciences/ Roussel Uclaf Causality Assessment Method (CIOMS/ RUCAM) scale,may be helpful for the fi nal diagnosis. Early management of DILI involves prompt withdrawal of the drug suspected of being responsible,according to serum levels of alanine aminotransferase (ALT),alkaline phosphatase (ALP),and total bilirubin (T-Bil). However,as DILI patients may show resolution of liver injury without discontinuation of the drug,it should be carefully evaluated whether the suspected drug should be discontinued immediately with adequate consideration of the importance of the medication.
文摘The classic view on the pathogenesis of drug-induced liver injury is that the so-called parent compounds are made hepatotoxic by metabolism (formation of neosubstances that react abnormally), mainly by cytochromes P-450 (CYP), with further pathways, such as mitochondrial dysfunction and apoptosis, also playing a role. Risk factors for drug-induced liver injury include concomitant hepatic diseases, age and genetic polymorphisms of CYP. However, some susceptibility can today be predicted before drug administration, working on the common substrate, by phenotyping and genotyping studies and by taking in consideration patients' health status. Physicians should always think of this adverse effect in the absence of other clear hepatic disease. Ethical and legal problems towards operators in the health care system are always matters to consider.
文摘Interest in drug-induced liver injury(DILI) has dramatically increased over the past decade, and it has become a hot topic for clinicians, academics, pharmaceutical companies and regulatory bodies. By investigating the current state of the art, the latest scientific findings, controversies, and guidelines, this review will attempt to answer the question: Do we know everything? Since the first descriptions of hepatotoxicity over 70 years ago, more than 1000 drugs have been identified to date, however, much of our knowledge of diagnostic and pathophysiologic principles remains unchanged. Clinically ranging from asymptomatic transaminitis and acute or chronic hepatitis, to acute liver failure, DILI remains a leading causes of emergent liver transplant. The consumption of unregulated herbal and dietary supplements has introduced new challenges in epidemiological assessment and clinician management. As such, numerous registries have been created, including the United States Drug-Induced Liver Injury Network, to further our understanding of all aspects of DILI. The launch of Liver Tox and other online hepatotoxicity resources has increased our awareness of DILI. In 2013, the first guidelines for the diagnosis and management of DILI, were offered by the Practice Parameters Committee of the American College of Gastroenterology, and along with the identification of risk factors and predictors of injury, novel mechanisms of injury, refined causality assessment tools, and targeted treatment options have come to define the current state of the art, however, gaps in our knowledge still undoubtedly remain.

文摘Drug-induced liver injury(DILI) has become a major topic in the field of Hepatology and Gastroenterology. DILI can be clinically divided into three phenotypes: hepatocytic, cholestatic and mixed. Although the clinical manifestations of DILI are variable and the pathogenesis complicated, recent insights using improved preclinical models, have allowed a better understanding of the mechanisms that trigger liver damage. In this review, we will discuss the pathophysiological mechanisms underlying DILI. The toxicity of the drug eventually induces hepatocellular damage through multiple molecular pathways, including direct hepatic toxicity and innate and adaptive immune responses. Drugs or their metabolites, such as the common analgesic, acetaminophen, can cause direct hepatic toxicity through accumulation of reactive oxygen species and mitochondrial dysfunction. The innate and adaptive immune responses play also a very important role in the occurrence of idiosyncratic DILI. Furthermore, we examine common forms of hepatocyte death and their association with the activation of specific signaling pathways.

文摘AIM:To identify the proportion,causes and the nature of drug-induced liver injury(DILI) in patients with notably elevated alanine aminotransferase(ALT).METHODS:All the inpatients with ALT levels above 10 times upper limit of normal range(ULN) were retrospectively identified from a computerized clinical laboratory database at our hospital covering a 12-mo period.Relevant clinical information was obtained from medical records.Alternative causes of ALT elevations were examined for each patient,including biliary abnormality,viral hepatitis,hemodynamic injury,malignancy,DILI or undetermined and other causes.All suspected DILI cases were causality assessed using the Council for International Organizations of Medical Sciences scale,and only the cases classified as highly probable,probable,or possible were diagnosed as DILI.Comments related to the diagnosis of DILI in the medical record and in the discharge letter for each case were also examined to evaluate DILI detection by the treating doctors.RESULTS:A total of 129 cases with ALT > 10 ULN were identified.Hemodynamic injury(n = 46,35.7%),DILI(n = 25,19.4%) and malignancy(n = 21,16.3%) were the top three causes of liver injury.Peak ALT values were lower in DILI patients than in patients with hemodynamic injury(14.5 ± 5.6 ULN vs 32.5 ± 30.7 ULN,P = 0.001).Among DILI patients,one(4%) case was classified as definite,19(76%) cases were classified as probable and 5(20%) as possible according to the CIOMS scale.A hepatocellular pattern was observed in 23(92%) cases and mixed in 2(8%).The extent of severity of liver injury was mild in 21(84%) patients and moderate in 4(16%).Before discharge,10(40%) patients were recovered and the other 15(60%) were improved.The improved patients tended to have a higher peak ALT(808 ± 348 U/L vs 623 ± 118 U/L,P = 0.016) and shorter treatment duration before discharge(8 ± 6 d vs 28 ± 12 d,P = 0.008) compared with the recovered patients.Twenty-two drugs and 6 herbs were found associated with DILI.Antibacterials were the most common agents causing DILI in 8(32%) cases,followed by glucocorticoids in 6(24%) cases.Twenty-four(96%) cases received treatment of DILI with at least one adjunctive drug.Agents for treatment of DILI included anti-inflammatory drugs(e.g.,glycyrrhizinate),antioxidants(e.g.,glutathione,ademetionine 1,4-butanedisulfonate and tiopronin),polyene phosphatidyl choline and herbal extracts(e.g.,protoporphyrin disodium and silymarin).Diagnosis of DILI was not mentioned in the discharge letter in 60% of the cases.Relative to prevalent cases and cases from wards of internal medicine,incident cases and cases from surgical wards had a higher risk of missed diagnosis in discharge letter [odds ratio(OR) 32.7,95%CI(2.8-374.1),CONCLUSION:DILI is mostly caused by use of antibacterials and glucocorticoids,and constitutes about one fifth of hospitalized patients with ALT > 10 ULN.DILI is underdiagnosed frequently.

文摘Objective:To study the effect of pyrrolidine dithiocarbamate(PDTC) on the anti-tuberculosis drug-induced liver injury and the molecular mechanism. Methods:Clean male SD rats were selected as experimental animals and randomly divided into normal group,model group,PDTC group and AG490 group. Animal model of anti-tuberculosis drug-induced liver injury was established by intragastric administration isoniazid + rifampicin. PDTC group received intraperitoneal injection of PDTC,and AG490 group received intraperitoneal injection of AG490. Twenty-eight days after intervention,the rats were executed,and the liver injury indexes,inflammation indexes and oxidative stress indexes in serum as well as JAK2/STAT3 expression,liver injury indexes,inflammation indexes and oxidative stress indexes in liver tissue were determined. Results:p-JAK2,p-STAT3,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA expression in liver tissue as well as TBIL,ALT,AST,γ-GT,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA levels in serum of model group were significantly higher than those of normal group while p-JAK2,p-STAT3,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA expression in liver tissu as well as TBIL,ALT,AST,γ-GT,TNF-α,IL-1β,IL-6,ROS,8-OHdG and MDA levels in serum of PDTC group and AG490 group were significantly lower than those of model group. Conclusions:PDTC can inhibit the inflammation and oxidative stress mediated by JAK2/STAT3 signaling pathway to alleviate the anti-tuberculosis drug-induced liver injury.
文摘AIM To summarize and compare the clinical characteristics of drug-induced liver injury(DILI) and primary biliary cirrhosis(PBC).METHODS A total of 124 patients with DILI and 116 patients with PBC treated at Shengjing Hospital Affiliated to China Medical University from 2005 to 2013 were included. Demographic data(sex and age),biochemical indexes(total protein,albumin,alanine aminotransferase,aspartate aminotransferase,total bilirubin,direct bilirubin,indirect bilirubin,alkaline phosphatase,and gamma glutamyltransferase),immunological indexes [immunoglobulin(Ig) A,Ig G,Ig M,antinuclear antibody,anti-smooth muscle antibody,anti-mitochondrial antibody,and anti-mitochondrial antibodies] and pathological findings were compared in PBC patients,untyped DILI patients and patients with different types of DILI(hepatocellular type,cholestatic type and mixed type). RESULTS There were significant differences in age and gender distribution between DILI patients and PBC patients. Biochemical indexes(except ALB),immunological indexes,positive rates of autoantibodies(except SMA),and number of cases of patients with different ANA titers(except the group at a titer of 1:10000)significantly differed between DILI patients and PBC patients. Biochemical indexes,immunological indexes,and positive rate of autoantibodies were not quite similar in different types of DILI. PBC was histologically characterized mainly by edematous degeneration of hepatocytes(n = 30),inflammatory cell infiltration around bile ducts(n = 29),and atypical hyperplasia of small bile ducts(n = 28). DILI manifested mainly as fatty degeneration of hepatocytes(n = 15) and spotty necrosis or loss of hepatocytes(n = 14).CONCLUSION Although DILI and PBC share some similar laboratory tests(biochemical and immunological indexes) and pathological findings,they also show some distinct characteristics,which are helpful to the differential diagnosis of the two diseases.
文摘AIM To analyze 1-year liver injury burden in inflammatory bowel disease(IBD) patients. METHODS During a 6-mo inclusion period, consecutive IBD cases having a control visit at IBD center were included. Basic demographics, IBD phenotype and IBD treatment were recorded on entry. Aminotransferase(AT) activities of ALT, AST, ALP and gamma-glutamyl transpeptidase(GGT) were measured at baseline, 3 mo prior to study entry and prospectively every 3 mo for 1 year. Liver injury patterns were predefined as: Grade 1 in ALT 1-3 × upper limit of normal(ULN), grade 2 in ALT > 3 × ULN, hepatocellular injury in ALT > 2 × ULN, cholestatic injury in simultaneous GGT and ALP elevation > ULN.Persisting injury was reported when AT elevations were found on > 1 measurement. Risk factors for the patterns of liver injury were identified among demographic parameters, disease phenotype and IBD treatment in univariate and multivariate analysis. Finally, implications for the change in IBD management were evaluated in cases with persisting hepatocellular or cholestatic injury.RESULTS Two hundred and fifty-one patients were included having 917 ALT and 895 ALP and GGT measurements. Over one year, grade 1 injury was found in 66(26.3%), grade 2 in 5(2%) and hepatocellular injury in 16 patients(6.4%). Persisting hepatocellular injury was found in 4 cases. Cholestasis appeared in 11 cases(4.4%) and persisted throughout the entire study period in 1 case. In multivariate analysis, hepatocellular injury was associated with BMI(OR = 1.13, 1.02-1.26), liver steatosis(OR = 10.61, 2.22-50.7), IBD duration(1.07, 1.00-1.15) and solo infliximab(OR = 4.57, 1.33-15.7). Cholestatic liver injury was associated with prior intestinal resection(OR = 32.7, 3.18-335), higher CRP(OR = 1.04, 1.00-1.08) and solo azathioprine(OR = 10.27, 1.46-72.3). In one case with transient hepatocellular injury azathioprine dose was decreased. In 4 cases with persisting hepatocellular injury, fatty liver or alcohol were most likely causes and IBD treatment was pursued without change. In the case with persisting cholestatic injury, no signs of portal hypertension were identified and treatment with infliximab continued.CONCLUSION Liver injury was frequent, mostly transient and rarely changed management. Infliximab or azathioprine were confirmed as its risk factors indicating the need for regular AT monitoring.
文摘Taking herbal-extracts to lose weight is an underestimated health hazard.Often,these products contain active agents that can cause acute liver damage.In this case report,a 22-year-old female patient,who presented with a feature of cholestatic syndrome,was so sure that the "natural products" were not dangerous that she did not inform her physicians that she had taken them,making their task that much more challenging.Clinical presentation mimicked acute cholecystitis and the patient underwent a cholecystectomy.Surgery was without any consequences and complications,although it did not completely cure the illness.She later admitted to having taken herbal remedies and this led to the correct diagnosis of phytotherapy-related hepatotoxicity and a successful therapeutic approach.The true incidence of phytotherapy-related hepatotoxicity and its pathogenic mechanisms are largely unknown.It is important to increase the awareness of both clinicians and patients about the potential dangers of herbal remedies.

文摘Summary: Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the Peo- ple's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance.
文摘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.

文摘Objective:To systematically evaluate the efficacy and safety of Hugan Tablets(护肝片)in the treatment of drug-induced liver injury.Methods:Totally seven Chinese and English databases,including CNKI,Wanfang,VIP,CBM,PubMed,EMbase,Web of Science were searched for randomized controlled trials(RCTs)of Hugan Tablets(护肝片)for the treatment of drug-induced liver injury,which were published from the date of establishment to April 20,2019.The meta-analysis software RevMan 5.3 software and Excel were used to build a database into combine and analyze the studies that met the standards and to draw a forest plot.Results:Forty five RCTs were included with 7478 patients.The quality of included studies was uneven.Meta-analysis showed that the outcome index of liver injury rate was divided into seven subgroups.Hugan Tablets(护肝片)were used in the treatment of anti-tuberculosis drugs was superior to the conventional western medicine treatment group(RR=0.27,95%CI[0.22,0.33],P<0.00001).Which was also better than the without Hugan Tablets(护肝片)treatment group(RR=0.32,95%CI[0.20,0.52],P<0.00001).For the role of drug-induced liver injury in the treatment of type 2 diabetes,the Hugan Tablet+conventional treatment group is better than the conventional treatment group(RR=0.16,95%CI[0.03,0.88],P=0.03).The effect of drug-induced liver injury in the treatment of hypertension was superior to the conventional western medicine treatment group(RR=0.07,95%CI[0.03,0.14],P<0.00001).The effect of drug-induced liver injury during the treatment of hyperlipidemia was not statistically significant(RR=0.57,95%CI[0.33,1.00],P=0.05).There was no statistical difference between the two groups in the effect of drug-induced liver injury during the treatment of coronary heart disease(RR=0.09,95%CI[0.01,1.61],P=0.10).There was no significant difference between the two groups in the treatment of cerebral thrombosis for drug-induced liver injury(RR=0.11,95%CI[0.01,2.01],P=0.14).The effect of anti-hyperthyroidism on liver injury was better than that of conventional western medicine treatment group(RR=0.45,95%CI[0.25,0.82],P=0.009).Outcome index of total effective rate was divided into two subgroups.The effect of drug-induced liver injury caused by the type of drug was not mentioned was superior to the conventional western medicine treatment group(RR=0.78,95%CI[0.70,0.88],P<0.0001).There was no significant difference between the two groups in the liver injury caused by antipsychotic drugs(RR=0.97,95%CI[0.81,1.16],P=0.72).Conclusion:When used in the treatment of tuberculosis and psychiatric drug treatment,combineduse of Hugan Tablets(护肝片)can significantly reduce the incidence of drug-induced liver damage,and can significantly improve clinical symptoms caused by liver damage.In the treatment of hypertension,the addition of Hugan Tablets(护肝片)can significantly reduce the incidence of drug-induced liver injury,improving the safety of medication.In the treatment of drug-induced liver injury caused by which drug is not mentioned,Hugan Tablet has a therapeutic effect.Slight adverse reactions were reported,including rash,headache,palpitations,hypoglycemia,flushing,fatigue,nausea,bowel sounds,flatulence,diarrhea,and gastrointestinal discomfort.All studies reported minor adverse reactions that were well tolerated by patients and recovered without treatment after discontinuation.Oral administration of Hugan Tablets(护肝片)has positive effects on druginduced liver injury,but this conclusion still needs further evidences delete.It is necessary to adopt a larger sample,more design,and accord with the international standards to improve the quality of evidence.
文摘Background/Aims: Antituberculosis drug-induced liver injury (TB DILI) is a frequent medical problem in Pakistan. Critical understanding of various aspects of TB DILI is not only important to manage liver injury but may also prevent unnecessary discontinuation of antituberculosis treatment. The study is aimed to determine the frequency, types, severity and patterns of TB DILI. Study further evaluates various risk factors of TB DILI. Materials and Methods: This is a prospective cohort study of two seventy-eight patients with the diagnosis of tuberculosis, where patients were followed during tuberculosis treatment. TB DILI was defined in accordance to international DILI expert working group. Results: Out of two seventy eight-patients, ninety-five (34.14%) had TB DILI. The most common pattern of TB DILI was hepatocellular (63.15%) followed by mixed (23.15%) and Cholestatic (13.68%). Most of the patients had mild DILI (43.15%) followed by moderate (30.52%), severe (20.01%) and very severe (5.26%). Age > 35 years, concomitant hepatotoxic drugs, extrapulmonary TB and malnutrition are important risk factors for TB DILI. Conclusion: All patterns of TB DILI with varying severity were present. Age > 35 years, malnutrition, extrapulmonary TB and concomitant use of hepatotoxic drugs were risk factors for TB DILI.
文摘Drug induced liver injury(DILI) is a common condition of increasing incidence. Many environmental and genetic factors are involved in its pathogenesis,and immunological mechanisms are also thought to contribute to the development and severity of DILI. This review summarizes current understanding of the immunological pathogenesis of DILI and discusses the perspective for clinical applications.
文摘Causality assessment of suspected drug induced liver injury(DILI) and herb induced liver injury(HILI) is hampered by the lack of a standardized approach to be used by attending physicians and at various subsequent evaluating levels. The aim of this review was to analyze the suitability of the liver specific Council for International Organizations of Medical Sciences(CIOMS) scale as a standard tool for causality assessment in DILI and HILI cases. PubMed database was searched for the following terms: drug induced liver injury; herb induced liver injury; DILI causality assessment; and HILI causality assessment. The strength of the CIOMS lies in its potential as a standardized scale for DILI and HILI causality assessment. Other advantages include its liver specificity and its validation for hepatotoxicity with excellent sensitivity, specificity and predictive validity, based on cases with a positive reexposure test. This scale allows prospective collection of all relevant data required for a valid causality assessment. It does not require expert knowledge in hepatotoxicity and its results may subsequently be refined. Weaknesses of the CIOMS scale include the limited exclusion of alternative causes and qualitatively graded risk factors. In conclusion, CIOMS appears to be suitable as a standard scale for attending physicians, regulatory agencies, expert panels and other scientists to provide a standardized, reproducible causality assessment in suspected DILI and HILI cases, applicable primarily at all assessing levels involved. 2014 Baishideng Publishing Group Co., Limited.
