Recent advances in the diagnosis of drug-induced liver injury

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.

Long non-coding RNA H19 regulates neurogenesis of induced neural stem cells in a mouse model of closed head injury

Stem cell-based therapies have been proposed as a potential treatment for neural regeneration following closed head injury.We previously reported that induced neural stem cells exert beneficial effects on neural regeneration via cell replacement.However,the neural regeneration efficiency of induced neural stem cells remains limited.In this study,we explored differentially expressed genes and long non-coding RNAs to clarify the mechanism underlying the neurogenesis of induced neural stem cells.We found that H19 was the most downregulated neurogenesis-associated lnc RNA in induced neural stem cells compared with induced pluripotent stem cells.Additionally,we demonstrated that H19 levels in induced neural stem cells were markedly lower than those in induced pluripotent stem cells and were substantially higher than those in induced neural stem cell-derived neurons.We predicted the target genes of H19 and discovered that H19 directly interacts with mi R-325-3p,which directly interacts with Ctbp2 in induced pluripotent stem cells and induced neural stem cells.Silencing H19 or Ctbp2 impaired induced neural stem cell proliferation,and mi R-325-3p suppression restored the effect of H19 inhibition but not the effect of Ctbp2 inhibition.Furthermore,H19 silencing substantially promoted the neural differentiation of induced neural stem cells and did not induce apoptosis of induced neural stem cells.Notably,silencing H19 in induced neural stem cell grafts markedly accelerated the neurological recovery of closed head injury mice.Our results reveal that H19 regulates the neurogenesis of induced neural stem cells.H19 inhibition may promote the neural differentiation of induced neural stem cells,which is closely associated with neurological recovery following closed head injury.

Insights into skullcap herb-induced liver injury

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.

Induced pluripotent stem cells for therapy personalization in pediatric patients:Focus on drug-induced adverse events

Adverse drug reactions(ADRs)are major clinical problems,particularly in special populations such as pediatric patients.Indeed,ADRs may be caused by a plethora of different drugs leading,in some cases,to hospitalization,disability or even death.In addition,pediatric patients may respond differently to drugs with respect to adults and may be prone to developing different kinds of ADRs,leading,in some cases,to more severe consequences.To improve the comprehension,and thus the prevention,of ADRs,the set-up of sensitive and personalized assays is urgently needed.Important progress is represented by the possibility of setting up groundbreaking patient-specific assays.This goal has been powerfully achieved using induced pluripotent stem cells(iPSCs).Due to their genetic and physiological species-specific differences and their ability to be differentiated ideally into all tissues of the human body,this model may be accurate in predicting drug toxicity,especially when this toxicity is related to individual genetic differences.This review is an up-to-date summary of the employment of iPSCs as a model to study ADRs,with particular attention to drugs used in the pediatric field.We especially focused on the intestinal,hepatic,pancreatic,renal,cardiac,and neuronal levels,also discussing progress in organoids creation.The latter are three-dimensional in vitro culture systems derived from pluripotent or adult stem cells simulating the architecture and functionality of native organs such as the intestine,liver,pancreas,kidney,heart,and brain.Based on the existing knowledge,these models are powerful and promising tools in multiple clinical applications including toxicity screening,disease modeling,personalized and regenerative medicine.

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.

drug-induced autoimmune liver disease:a diagnostic dilemma of an increasingly reported disease

The aetiology of autoimmune hepatitis(AIH) is uncer-tain but the disease can be triggered in susceptible patients by external factors such as viruses or drugs.AIH usually develops in individuals with a genetic back-ground mainly consisting of some risk alleles of the major histocompatibility complex(HLA).Many drugs have been linked to AIH phenotypes,which sometimes persist after drug discontinuation,suggesting that they awaken latent autoimmunity.At least three clini-cal scenarios have been proposed that refers to drug- induced autoimmune liver disease(DIAILD):AIH with drug-induced liver injury(DILI); drug induced-AIH(DI-AIH); and immune mediated DILI(IM-DILI).In addi-tion,there are instances showing mixed features of DI-AIH and IM-DILI,as well as DILI cases with positive autoantibodies.Histologically distinguishing DILI from AIH remains a challenge.Even more challenging is the differentiation of AIH from DI-AIH mainly relying in histological features; however,a detailed standard-ised histologic evaluation of large cohorts of AIH and DI-AIH patients would probably render more subtle features that could be of help in the differential diag-nosis between both entities.Growing information on the relationship of drugs and AIH is being available,being drugs like statins and biologic agents more fre-quently involved in cases of DIAILD.In addition,there is some evidence on the fact that patients diagnosed with DIAILD may have had a previous episode of hepa-totoxicity.Further collaborative studies in DIAILD will strengthen the knowledge and understanding of this intriguing and complex disorder which might represent different phenotypes across the spectrum of

The neuroprotective effects of the anti-diabetic drug linagliptin against Aβ-induced neurotoxicity

Impaired insulin signaling in Alzheimer’s disease（AD）brains：The insulin signaling pathway is a fundamental physiological mechanism that presents in nearly all vertebrate cells.However,sometimes cells stop responding properly to insulin stimulation.This condition is known as insulin resistance,which is a hallmark of two very common conditions,metabolic syndrome and type 2 diabetes（T2D）.

Pyrrolidine dithiocarbamate alleviates the anti-tuberculosis drug-induced liver injury through JAK2/STAT3 signaling pathway:An experimental study

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.

Contemporary review of drug-induced pancreatitis: A different perspective

Although gallstone and alcohol use have been consid-ered the most common causes of acute pancreatitis, hundreds of frequently prescribed medications are as-sociated with this disease state. The true incidence is unknown since there are few population based studies available. The knowledge of drug induced acute pan-creatitis is limited by the availability and the quality of the evidence as the majority of data is extrapolated from case reports. Establishing a definitive causal rela-tionship between a drug and acute pancreatitis poses a challenge to clinicians. Several causative agent classifi-cation systems are often used to identify the suspected agents. They require regular updates since new drug induced acute pancreatitis cases are reported continu-ously. In addition, infrequently prescribed medications and herbal medications are often omitted. Furthermore, identification of drug induced acute pancreatitis with new medications often requires accumulation of post market case reports. The unrealistic expectation for a comprehensive list of medications and the multifacto-rial nature of acute pancreatitis call for a different ap-proach. In this article, we review the potential mecha-nisms of drug induced acute pancreatitis and providethe perspective of deductive reasoning in order to allow clinicians to identify potential drug induced acute pan-creatitis with limited data.

Dissecting the molecular pathophysiology of drug-induced liver injury

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.

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.

Alectinib-Induced Immune Hemolytic Anemia in a Patient with Lung Adenocarcinoma: Case Report and Literature Review

Alectinib is a selective Anaplastic Lymphoma Kinase (ALK) tyrosine kinase inhibitor used as standard therapy for ALK-rearranged lung adenocarcinoma. Hemolytic anemia is considered a rare but significant adverse event of alectinib. Here, we report the case of a 78-year-old female with advanced ALK rearrangement-positive lung adenocarcinoma who developed grade 4 drug-induced hemolytic anemia after receiving alectinib as first-line therapy. We discontinued alectinib treatment and switched to brigatinib. As a result, anemia improved without recurrence of lung adenocarcinoma over one year.

Clinical characteristics of drug-induced liver injury and primary biliary cirrhosis

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.

Efficacy of Jian’ganle(健肝乐) versus Hugan Pian(护肝片),Glucuronolactone and Reduced Glutathione in Prevention of Antituberculosis Drug-induced Liver Injury

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.

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.

Application of Ji Desheng Snake Pills Combined with Hypertonic Glucose External Application in Treating Drug-Induced Superficial Phlebitis Caused by Parenteral Nutrition

Objective: The efficacy of Ji Desheng snake pills combined with hypertonic glucose external application in treating drug-induced superficial phlebitis caused by parenteral nutrition (PN) is observed. Methods: Fifty-two cases of drug-induced superficial phlebitis after peripheral parenteral nutrition (PPN) were selected, which were randomly divided into experimental group and control group in accordance with the phlebitis grading. In the experimental group, Ji Desheng snake pills were crushed to make a paste with 50% glucose solution, which was then applied to the affected area of phlebitis, the surface was covered with clean gauze, and properly fixed with tape or bandage. The drug was replaced once a day. In the control group, the gauze soaked with 50% magnesium sulfate solution was used, which was applied to the affected part three times a day in wet, and the efficacy was observed respectively on the 1st, 3rd, 5th and 7th days after applying the drug. Results: On the 1st and 3rd days after treatment, the observed effective rate of the experimental group was higher than that of the control group (42.31% vs. 15.38% and 76.92% vs. 46.15%, respectively). The difference was statistically significant (p th and 7th days after treatment, there was no statistical significance with respect to the efficacy between the experimental group and the control group (p > 0.05). Conclusion: The significant efficacy could be found in early stage after drug-induced superficial phlebitis was treated by Ji Desheng snake pills combined with hypertonic glucose external application, which was superior to that of the traditional treatment of wet application by using gauze soaked in 50% magnesium sulfate solution.

Drug-induced liver injury and COVID-19:Use of artificial intelligence and the updated Roussel Uclaf Causality Assessment Method in clinical practice

BACKGROUND Liver injury is a relevant condition in coronavirus disease 2019(COVID-19)inpatients.Pathophysiology varies from direct infection by virus,systemic inflammation or drug-induced adverse reaction(DILI).DILI detection and monitoring is clinically relevant,as it may contribute to poor prognosis,prolonged hospitalization and increase indirect healthcare costs.Artificial Intelligence(AI)applied in data mining of electronic medical records combining abnormal liver tests,keyword searching tools,and risk factors analysis is a relevant opportunity for early DILI detection by automated algorithms.AIM To describe DILI cases in COVID-19 inpatients detected from data mining in electronic medical records(EMR)using AI and the updated Roussel Uclaf Causality Assessment Method(RUCAM).METHODS The study was conducted in March 2021 in a hospital in southern Brazil.The NoHarm©system uses AI to support decision making in clinical pharmacy.Hospital admissions were 100523 during this period,of which 478 met the inclusion criteria.From these,290 inpatients were excluded due to alternative causes of liver injury and/or due to not having COVID-19.We manually reviewed the EMR of 188 patients for DILI investigation.Absence of clinical information excluded most eligible patients.The DILI assessment causality was possible via the updated RUCAM in 17 patients.RESULTS Mean patient age was 53 years(SD±18.37;range 22-83),most were male(70%),and admitted to the non-intensive care unit sector(65%).Liver injury pattern was mainly mixed,mean time to normalization of liver markers was 10 d,and mean length of hospitalization was 20.5 d(SD±16;range 7-70).Almost all patients recovered from DILI and one patient died of multiple organ failure.There were 31 suspected drugs with the following RUCAM score:Possible(n=24),probable(n=5),and unlikely(n=2).DILI agents in our study were ivermectin,bicalutamide,linezolid,azithromycin,ceftriaxone,amoxicillin-clavulanate,tocilizumab,piperacillin-tazobactam,and albendazole.Lack of essential clinical information excluded most patients.Although rare,DILI is a relevant clinical condition in COVID-19 patients and may contribute to poor prognostics.CONCLUSION The incidence of DILI in COVID-19 inpatients is rare and the absence of relevant clinical information on EMR may underestimate DILI rates.Prospects involve creation and validation of alerts for risk factors in all DILI patients based on RUCAM assessment causality,alterations of liver biomarkers and AI and machine learning.

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.

Systematic Review and Meta-Analysis of Hugan Tablets (护肝片) in the Treatment of Drug-Induced Liver Injury

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.

Antituberculosis Drug-Induced Liver Injury: An Ignored Fact, Assessment of Frequency, Patterns, Severity and Risk Factors

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.
