Abstract
INTRODUCTION Data on positive rechallenge in idiosyncratic drug-induced liver injury (DILI) are scarce. We aim to analyse the clinical presentation, outcome and drugs associated with positive rechallenge in two DILI registries. METHODS Cases from the Spanish and Latin American DILI registries were included. Demographics, clinical characteristics and outcome of cases with positive rechallenge according to CIOMS/RUCAM and current definitions were analysed. RESULTS Of 1418 patients with idiosyncratic DILI, 58 cases had positive rechallenge (4.1%). Patients with positive rechallenge had shorter duration of therapy (p=0.001) and latency (p=0.003). In patients with rechallenge, aspartate transaminase levels were increased (p=0.026) and showed a prolonged time to recovery (p=0.020), albeit no differences were seen in terms of fatal outcomes. The main drug implicated in rechallenge was amoxicillin-clavulanate (17%). The majority of re-exposure events were unintentional (71%). Using both existing definitions of positive rechallenge, there were four cases which exclusively fulfilled the current criteria and five which only meet the historical definition. All cases of positive rechallenge, irrespective of the pattern of damage, fulfilled the criteria of either alanine transaminase (ALT) ≥3 times the upper limit of normal (ULN) and/or alkaline phosphatase (ALP) ≥2 times ULN. CONCLUSIONS Episodes of rechallenge were characterised by shorter duration of therapy and latency, and longer time to resolution, but did not show an increased incidence of fatal outcome. Based on our findings, ALT ≥3 times ULN and/or ALP ≥2 times ULN, regardless of the pattern of damage, is proposed as a new definition of rechallenge in DILI.

Abstract
In the current article the aims for a constructive way forward in Drug-Induced Liver Injury (DILI) are to highlight the most important priorities in research and clinical science, therefore supporting a more informed, focused, and better funded future for European DILI research. This Roadmap aims to identify key challenges, define a shared vision across all stakeholders for the opportunities to overcome these challenges and propose a high-quality research program to achieve progress on the prediction, prevention, diagnosis and management of this condition and impact on healthcare practice in the field of DILI. This will involve 1. Creation of a database encompassing optimised case report form for prospectively identified DILI cases with well-characterised controls with competing diagnoses, biological samples, and imaging data; 2. Establishing of preclinical models to improve the assessment and prediction of hepatotoxicity in humans to guide future drug safety testing; 3. Emphasis on implementation science and 4. Enhanced collaboration between drug-developers, clinicians and regulatory scientists. This proposed operational framework will advance DILI research and may bring together basic, applied, translational and clinical research in DILI.

Abstract
Drug-induced liver injury (DILI) development is commonly associated with acetaminophen (APAP) overdose, where glutathione scavenging leads to mitochondrial dysfunction and hepatocyte death. DILI is a severe disorder without effective late-stage treatment, since N-acetyl cysteine must be administered 8 h after overdose to be efficient. Ammonia homeostasis is altered during liver diseases and, during DILI, it is accompanied by decreased glycine N-methyltransferase (GNMT) expression and S-adenosylmethionine (AdoMet) levels that suggest a reduced methionine cycle. Anti-miR-873-5p treatment prevents cell death in primary hepatocytes and the appearance of necrotic areas in liver from APAP-administered mice. In our study, we demonstrate a GNMT and methionine cycle activity restoration by the anti-miR-873-5p that reduces mitochondrial dysfunction and oxidative stress. The lack of hyperammoniemia caused by the therapy results in a decreased urea cycle, enhancing the synthesis of polyamines from ornithine and AdoMet and thus impacting the observed recovery of mitochondria and hepatocyte proliferation for regeneration. In summary, anti-miR-873-5p appears to be an effective therapy against APAP-induced liver injury, where the restoration of GNMT and the methionine cycle may prevent mitochondrial dysfunction while activating hepatocyte proliferative response.

Abstract
A percentage of hepatitis C virus (HCV)-infected patients fail direct acting antiviral (DAA)-based treatment regimens, often because of drug resistance-associated substitutions (RAS). The aim of this study was to characterize the resistance profile of a large cohort of patients failing DAA-based treatments, and investigate the relationship between HCV subtype and failure, as an aid to optimizing management of these patients. A new, standardized HCV-RAS testing protocol based on deep sequencing was designed and applied to 220 previously subtyped samples from patients failing DAA treatment, collected in 39 Spanish hospitals. The majority had received DAA-based interferon (IFN) α-free regimens; 79% had failed sofosbuvir-containing therapy. Genomic regions encoding the nonstructural protein (NS) 3, NS5A, and NS5B (DAA target regions) were analyzed using subtype-specific primers. Viral subtype distribution was as follows: genotype (G) 1, 62.7%; G3a, 21.4%; G4d, 12.3%; G2, 1.8%; and mixed infections 1.8%. Overall, 88.6% of patients carried at least 1 RAS, and 19% carried RAS at frequencies below 20% in the mutant spectrum. There were no differences in RAS selection between treatments with and without ribavirin. Regardless of the treatment received, each HCV subtype showed specific types of RAS. Of note, no RAS were detected in the target proteins of 18.6% of patients failing treatment, and 30.4% of patients had RAS in proteins that were not targets of the inhibitors they received. HCV patients failing DAA therapy showed a high diversity of RAS. Ribavirin use did not influence the type or number of RAS at failure. The subtype-specific pattern of RAS emergence underscores the importance of accurate HCV subtyping. The frequency of "extra-target" RAS suggests the need for RAS screening in all three DAA target regions.

Abstract
Abstract
Background and aims
Chronic infection with hepatitis B virus (HBV) can progress to liver cirrhosis and lead to complications such as decompensated liver disease, hepatocellular carcinoma and liver-related death. Antiviral agents against HBV are very effective in suppressing viremia and greatly reduce the risk of complications if treatment is initiated before the onset of advanced liver disease. The aim of this study is to assess the prevalence of late presentation in leading hospitals across Spain.
Methods
Retrospective cohort study of patients seeking first time care with a liver specialist at six tertiary Spanish hospitals, with 2018 data. Late presentation (LP) included advanced liver disease (ALD) defined by significant fibrosis (≥ F3 assessed by either APRI score > 1.5, FIB-4 > 3.2, transient elastography (FibroScan) > 9.5 kPa or biopsy ≥ METAVIR stage F3) with no previous antiviral treatment and late-stage liver disease (LSLD) was defined by the presence of decompensated cirrhosis and/or hepatocellular carcinoma. Prevalence of ALD and LSLD at first consultation, demographics, and associated risk factors were analysed.
Results
203 patients chronically infected with HBV were included. Advanced liver disease was detected in 14.8% and late stage liver disease was observed in 6.1% of cases. 57.1% of the cases were male. The majority of those with HBV were non-Spanish (53.7%). The median age was 47 and the median of years from diagnosis to specialist care was 1 (IQR 7). 58.6% of patients were referred from primary care and 3.7% cases had hepatocellular carcinoma upon presentation for care.
Conclusions
Late presentation with HBV is common in Spain, particularly for the foreign-born population, despite full access to antiviral therapy for HBV in the country. In order to rectify this health systems failure, improve outcomes and reach the viral hepatitis elimination goal adopted by WHO in 2016, strategies to reduce late presentation to care are essential.
Key messages
Early diagnosis of HBV is needed in order to rectify the health systems failure of late presentation to care. Interventions targeting foreign-born populations should be implemented to reduce late presentation to HBV care and treatment.

Abstract
It is recognized that stretching is an effective method to chronically increase the joint range of motion. However, the effects of stretching training on the muscle-tendon structural properties remain unclear. This systematic review with meta-analysis aimed to determine whether chronic stretching alter the muscle-tendon structural properties. Published papers regarding longitudinal stretching (static, dynamic and/or PNF) intervention (either randomized or not) in humans of any age and health status, with more than 2 weeks in duration and at least 2 sessions per week, were searched in PubMed, PEDro, ScienceDirect and ResearchGate databases. Structural or mechanical variables from joint (maximal tolerated passive torque or resistance to stretch) or muscle-tendon unit (muscle architecture, stiffness, extensibility, shear modulus, volume, thickness, cross-sectional area, and slack length) were extracted from those papers. A total of 26 studies were selected, with a duration ranging from 3 to 8 weeks, and an average total time under stretching of 1165 seconds per week. Small effects were seen for maximal tolerated passive torque, but trivial effects were seen for joint resistance to stretch, muscle architecture, muscle stiffness, and tendon stiffness. A large heterogeneity was seen for most of the variables. Stretching interventions with 3- to 8-week duration do not seem to change either the muscle or the tendon properties, although it increases the extensibility and tolerance to a greater tensile force. Adaptations to chronic stretching protocols shorter than 8 weeks seem to mostly occur at a sensory level.

Abstract
BACKGROUND High-quality data on the management of autoimmune hepatitis (AIH) are scarce. Despite published guidelines, management of AIH is still expert based rather than evidence based. AIM To survey expert hepatologists, asking each to describe their practices in the management of patients with AIH. METHODS A survey questionnaire was distributed to members of the International AIH Group. The questionnaire consisted of four clinical scenarios on different presentations of AIH. RESULTS Sixty surveys were sent, out of which 37 were returned. None reported budesonide as a first line induction agent for the acute presentation of AIH. Five (14%) participants reported using thiopurine S-methyltransferase measurements before commencement of thiopurine maintenance therapy. Thirteen (35%) routinely perform liver biopsy at 2 years of biochemical remission. If histological inflammatory activity is absent, four (11%) participants reduced azathioprine, whereas 10 (27%) attempted withdrawal altogether. Regarding the management of difficult-to-treat patients, mycophenolate mofetil is the most widely used second-line agent (n = ~450 in 28 centres), whereas tacrolimus (n = ~115 in 21 centres) and ciclosporin (n = ~112 in 18 centres) are less often reported. One centre reported considerable experience with infliximab, while rescue therapy with rituximab has been tried in seven centres. CONCLUSIONS There is a wide variation in the management of patients with autoimmune hepatitis even among the most expert in the field. Although good quality evidence is lacking, there is considerable experience with second-line therapies. Future prospective studies should address these issues, so that we move from an expert- to an evidence- and personalised-based care in autoimmune hepatitis.

Abstract
The shear wave velocity dispersion was analyzed in the Achilles tendon (AT) during passive dorsiflexion using a phase velocity method in order to obtain the tendon shear modulus (C 55). Based on this analysis, the aims of the present study were (i) to assess the reproducibility of the shear modulus for different ankle angles, (ii) to assess the effect of the probe locations, and (iii) to compare results with elasticity values obtained with the supersonic shear imaging (SSI) technique. The AT shear modulus (C 55) consistently increased with the ankle dorsiflexion (N = 10, p < 0.05). Furthermore, the technique showed a very good reproducibility (all standard error of the mean values <10.7 kPa and all coefficient of variation (CV) values ⩽ 0.05%). In addition, independently from the ankle dorsiflexion, the shear modulus was significantly higher in the proximal location compared to the more distal one. The shear modulus provided by SSI was always lower than C55 and the difference increased with the ankle dorsiflexion. However, shear modulus values provided by both methods were highly correlated (R = 0.84), indicating that the conventional shear wave elastography technique (SSI technique) can be used to compare tendon mechanical properties across populations. Future studies should determine the clinical relevance of the shear wave dispersion analysis, for instance in the case of tendinopathy or tendon tear.

Abstract
BACKGROUND We have observed an increase in hepatotoxicity (DILI) reporting related to the use of anabolic androgenic steroids (AAS) for bodybuilding. AIM To characterise phenotype presentation, outcome and severity of AAS DILI. METHODS Data on 25 cases of AAS DILI reported to the Spanish (20) and Latin-American (5) DILI Registries were collated and compared with previously published cases. RESULTS AAS DILI increased from representing less than 1% of the total cases in the Spanish DILI Registry in the period 2001-2009 to 8% in 2010-2013. Young men (mean age 32 years), requiring hospitalisation, hepatocellular injury and jaundice were predominating features among the AAS cases. AAS DILI caused significantly higher bilirubin values independent of type of damage when compared to other drug classes (P = 0.001). Furthermore, the cholestatic AAS cases presented significantly higher mean peak bilirubin (P = 0.029) and serum creatinine values (P = 0.0002), compared to the hepatocellular cases. In a logistic regression model, the interaction between peak bilirubin values and cholestatic damage was associated with the development of AAS-induced acute kidney impairment (AKI) [OR 1.26 (95% CI: 1.035-1.526); P = 0.021], with 21.5 ×ULN being the best bilirubin cut-off point for predicting AKI risk (AUCROC 0.92). No fatalities occurred. CONCLUSIONS Illicit recreational AAS use is a growing cause of reported DILI that can lead to severe hepatic and renal injury. AAS DILI is associated with a distinct phenotype, characterised by considerable bilirubin elevations independent of type of damage. Although hepatocellular injury predominates, acute kidney injury develops in cholestatic cases with pronounced jaundice.

Abstract
OBJECTIVES The hepatotoxic potential of statins is controversial. The objectives of this study were to describe the relative frequency of hepatotoxicity caused by statins and the phenotypes found in Spain. PATIENTS AND METHODS The incidence of hepatotoxicity attributed to statins in the Spanish Hepatotoxicity Registry (REH) were studied and compared with those attributed to other drugs. RESULTS Between April 1994 and August 2012, the REH included a total of 858 cases of which 47 (5.5 %) were attributed to statins. Of these, 16 were due to atorvastatin (34 %); 13 to simvastatin (27.7 %); 12 to fluvastatin (25.5 %); 4 to lovastatin (8.5 %) and 2 to pravastatin (4.3 %). Statins represented approximately half of the cardiovascular group which occupied 3rd place (10 %), after anti-infectious agents (37 %) and central nervous system drugs (14 %). The hepatocellular pattern was predominant, especially in the simvastatin group (85%), the cholestatic/mixed pattern was more frequent with fluvastatin (66 %) and had a similar distribution to atorvastatin. Patients with statin-induced toxicity were older (62 years versus 53 years, p < 0.001) and more often demonstrated anautoimmune hepatitis phenotype (8.5 % versus 1.4 %, p < 0.003). CONCLUSIONS Statins are not a common cause of hepatotoxicity in Spain. Atorvastatin is the statin involved in the greatest number of incidents. The liver injury pattern varies among the different statins. The hepatitis phenotype with autoimmune features appears to be a characteristic signature of statin-induced hepatotoxicity.

Abstract
Hepatitis C virus (HCV) interacts with lipid receptors to enter the cell, circulates as lipoviroparticle and is secreted as VLDL. We aimed to investigate the role of the rs12979860 polymorphism in the IL28B gene in 143 with chronic hepatitis C genotype 1, 144 infected with genotype 3, 90 genotype 4 and 413 noninfected individuals on lipid profile and to test the impact of HCV infection in an in vitro model on VLDL biosynthesis-related gene expression rs12979860 polymorphism was analysed using real-time PCR coupled to Fluorescence Resonance Energy Transfer (FRET). Huh7.5 (rs12979860 CT) and Huh7 (genotype CC) cells were infected with JFH-1 particles and serum from patients infected with genotypes 1 and 3. Gene expression of apolipoprotein B (apoB), microsomal triglyceride transfer protein (MTP), acetyl CoA carboxylase (ACC), diacylglycerol acyltransferase 2 (DGAT2), diacylglycerol acyltransferase 1 (DGAT1) and low-density lipoprotein receptor (LDLr) genes were determined by semiquantitative RT-PCR in vivo and in vitro. Genotype CC rs12979860 polymorphism was associated with significantly higher serum LDL and total cholesterol levels in patients with hepatitis C genotype 1 but not in patients with hepatitis C genotype 3, genotype 4 and control (noninfected) population. Genotype CC was more often seen in genotype 3 and healthy people in comparison with genotype 1; P = 0.001. In vitro results showed that HCV infection promotes lipid metabolism gene expression induction depending on viral genotype, but to a lesser extent in cells with CT genotype. These results demonstrate that IL28B genotype influences lipid metabolism in patients with hepatitis C but not in noninfected and it seems to be viral genotype-mediated. HCV infection modifies lipid-related genes expression (DGAT1 and DGAT2) in cultured cells based on viral genotype and IL28 polymorphism.

Abstract
Our understanding of the mechanisms by which nonalcoholic fatty liver disease (NAFLD) progresses from simple steatosis to steatohepatitis (NASH) is still very limited. Despite the growing number of studies linking the disease with altered serum metabolite levels, an obstacle to the development of metabolome-based NAFLD predictors has been the lack of large cohort data from biopsy-proven patients matched for key metabolic features such as obesity. We studied 467 biopsied individuals with normal liver histology (n=90) or diagnosed with NAFLD (steatosis, n=246; NASH, n=131), randomly divided into estimation (80% of all patients) and validation (20% of all patients) groups. Qualitative determinations of 540 serum metabolite variables were performed using ultraperformance liquid chromatography coupled to mass spectrometry (UPLC-MS). The metabolic profile was dependent on patient body-mass index (BMI), suggesting that the NAFLD pathogenesis mechanism may be quite different depending on an individual's level of obesity. A BMI-stratified multivariate model based on the NAFLD serum metabolic profile was used to separate patients with and without NASH. The area under the receiver operating characteristic curve was 0.87 in the estimation and 0.85 in the validation group. The cutoff (0.54) corresponding to maximum average diagnostic accuracy (0.82) predicted NASH with a sensitivity of 0.71 and a specificity of 0.92 (negative/positive predictive values=0.82/0.84). The present data, indicating that a BMI-dependent serum metabolic profile may be able to reliably distinguish NASH from steatosis patients, have significant implications for the development of NASH biomarkers and potential novel targets for therapeutic intervention.

Abstract
BACKGROUND & AIMS Multiple instances of DILI in the same patient with drugs of similar structure or function as well as completely unrelated drugs are not well understood and poorly documented. We have sought evidence of the frequency and characteristics of patients who have experienced two DILI episodes due to different drugs. METHODS All cases of DILI systematically collected in the Spanish DILI Registry between 1994 and 2009 were retrieved. Data on demographics, clinical, laboratory and pathological findings, and outcome were analyzed. RESULTS Nine patients (mean age 67 years, four women) out of 742, 1.21%, had evidence of two DILI episodes caused by different drugs. In four cases DILI was associated with structurally related drugs and in an additional two cases the drugs had a common target. In another case, unrelated antibiotics were implicated. In only two cases, the two drugs/herbals were not related in structure or function. All but one patient exhibited hepatocellular damage. The type of damage was consistent in both DILI episodes. Four cases presented as autoimmune hepatitis (AIH) in the second episode. CONCLUSIONS Multiple episodes of DILI in association with different drugs occur infrequently. In each individual, the type of injury was similar during the two DILI episodes, regardless of the causative drug. Second episodes of DILI are more likely to be associated with features of AIH. It remains uncertain if this is drug-induced unmasking of true AIH or DILI with autoimmune features. These cases illustrate the dilemma faced by clinicians in distinguishing these possibilities.

Abstract
BACKGROUND toxic liver damage associated with the use of natural remedies is a growing health problem. OBJECTIVES to analyze the demographics, and clinical and epidemiological characteristics of patients developing liver injury related to these remedies. PATIENTS AND METHODS all DILI cases associated with the use of herbal remedies (HR) or dietary supplements (DS) submitted to the Spanish Registry were analyzed. Type of liver damage, severity, and outcome were specifically evaluated. RESULTS thirteen cases out of 521 DILI cases (2%) submitted to the Spanish Liver Toxicity Registry between 1994 and 2006 were related to HR/DS, which ranked as the 10th therapeutic group with a greater number of cases and above pain killers, anxiolytics, and antipsychotic drugs. Nine patients (69%) were female (mean age 45 years). Nine cases (69%) had jaundice at presentation. The predominating type of liver damage was hepatocellular (12; 92%), and 31% of cases exhibited the common features of hypersensitivity. Camellia sinensis (3, 23%) was the main causative herb, followed by Rhamnus purshianus and isoflavones (Fitosoja(R), Biosoja(R)) (2 cases each, 15%). Three cases (23%) were rechallenged with the offending product. CONCLUSIONS the incidence of hepatic damage related to HR/DS is not so rare, the most common profile of affected patients being a woman with acute hepatocellular hepatitis. Low suspicion regarding the putative role of herbs in hepatotoxicity makes diagnosis more difficult, and probably increases the incidence of inadvertent rechallenge in these patients.

Abstract
Although antibiotics are the most commonly incriminated drugs in instances of hepatotoxicity in medical literature. However, it is mainly due to its wide prescription and the absolute risk of hepatotoxicity related to antibiotic use is thought to be low. Nevertheless, among the different penicillins, amoxicillin-clavulanate is the single leading drug involved in hepatotoxicity in cohorts of patients with drug-induced liver injury (DILI), representing between 12.8% to 14% of the cases. It is the most frequent cause of hospitalization for DILI. The incidence of amoxicillin-clavulanate induced hepatotoxicity has been estimated to be 9.91 per 100,000 users and its clinical presentation varies, the type of injury strongly influenced by age, with the hepatocelullar pattern predominating in younger patients and the cholestatic/mixed ones in older subjects. Among macrolides, erythromycin is a classical example of drug capable of inducing cholestatic injury. Recently, concern has arisen regarding telithromycin, a new generation macrolide, is hepatotoxic came from the identification of several cases of DILI related to this drug, with a typical signature, including abrupt commence of fever, abdominal pain, jaundice and ascites in some cases. Tetracyclines, especially in intravenous high doses, may be associated with dose-dependent microvesicular steatosis, and minocycline has been involved in an autoimmune like type I hepatitis. Quinolones, in spite of their extensive use in patients with cirrhosis and biliary infections, have been very rarely associated with hepatotoxicity.

Abstract
BACKGROUND Causality assessment in hepatotoxicity is challenging. The current standard liver-specific Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method scale is complex and difficult to implement in daily practice. The Naranjo Adverse Drug Reactions Probability Scale is a simple and widely used nonspecific scale, which has not been specifically evaluated in drug-induced liver injury. AIM To compare the Naranjo method with the standard liver-specific Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method scale in evaluating the accuracy and reproducibility of Naranjo Adverse Drug Reactions Probability Scale in the diagnosis of hepatotoxicity. METHODS Two hundred and twenty-five cases of suspected hepatotoxicity submitted to a national registry were evaluated by two independent observers and assessed for between-observer and between-scale differences using percentages of agreement and the weighted kappa (kappa(w)) test. RESULTS A total of 249 ratings were generated. Between-observer agreement was 45% with a kappa(w) value of 0.17 for the Naranjo Adverse Drug Reactions Probability Scale, while there was a higher agreement when using the Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method scale (72%, kappa(w): 0.71). Concordance between the two scales was 24% (kappa(w): 0.15). The Naranjo Adverse Drug Reactions Probability Scale had low sensitivity (54%) and poor negative predictive value (29%) and showed a limited capability to distinguish between adjacent categories of probability. CONCLUSION The Naranjo scale lacks validity and reproducibility in the attribution of causality in hepatotoxicity.

Abstract
BACKGROUND AND PURPOSE The general view on the pathogenesis of drug-induced idiosyncratic liver injury (DILI) is that parent compounds are rendered hepatotoxic by metabolism, mainly by cytochrome (CYP) 450, although other metabolic pathways can contribute. Anecdotal reports suggest a role of CYP 450 polymorphisms in DILI. We aimed to assess in a series of Spanish DILI patients the prevalence of important allelic variants of CYP2C9 and CYP2C19, known to be involved in the metabolism of several hepatotoxic drugs. EXPERIMENTAL APPROACH Genotyping of CYP2C9 ((*)2, (*)3) and CYP2C19 ((*)2 and (*)3), was carried out in a total of 28 and 32 patients with a well established diagnosis of DILI. CYP2C9 and CYP2C19 variants were analysed in genomic DNA by means of PCR-FRET and compared with previous findings in other Caucasian populations. KEY RESULTS CYP2C9 and CYP2C19 allele and genotype frequencies were in agreement with Hardy-Weinberg equilibrium. Fourteen patients (50%) were heterozygous and 1(4%) found to be compound heterozygous for the CYP2C9 allele. Seven (22%) were found to carry one and 1(3%) carried two CYP2C19 mutated alleles. No patients were homozygous for (*)3 allele. The distribution of both CYP2C9 and CYP2C19 allelic variants in DILI patients were similar to those in other Caucasian populations. Patients with variant and those with wild-type alleles did not differ in regard to clinical presentation of DILI, type of injury and outcome. CONCLUSIONS AND IMPLICATIONS We find no evidence to support CYP2C9 and CYP2C19 genetic polymorphisms as predictable potential risk factors for DILI.

Abstract
OBJECTIVES Analysis of all cases of tetrabamate (Atrium)-induced hepatotoxicity reported in the Andalusian Registry of drug-induced liver disorders and comparison with cases reported in the literature. MATERIAL AND METHOD Information was gathered in a structured protocol. The causal role of tetrabamate was estimated in each case using the diagnostic scale of the Council for International Organizations of Medical Sciences (CIOMS). RESULTS Of 327 cases of hepatotoxicity, 7 (2%) were due to tetrabamate. The mean age was 57 years (4 men). In 57% of the cases, the presenting symptom was tremor. The latency period was between 15 and 730 days. Liver damage was mainly cytolytic without signs of hypersensitivity. In all cases outcome was favorable with complete recovery between 60 and 120 days. The CIOMS diagnostic scale rated a causal role of tetrabamate as highly probable in six cases and as probable in one. CONCLUSION Tetrabamate can induce hepatotoxicity, probably due to an idiosyncratic metabolic mechanism. Because of this finding and the existence of more appropriate therapeutic alternatives, tetrabamate should not be used in the treatment of alcohol withdrawal.

Abstract
We present the case of a 63-year-old woman who had undergone 7 months of treatment with Nimesulide (100 mg/b.i.d.) for symptomatic osteoarthritis. The patient was admitted to our unit with a clinical picture of progressive jaundice over 3 weeks. Clinical and analytical studies revealed acute liver failure, this being confirmed by liver biopsy, which showed submassive necrosis. Serological tests for different viral agents causing hepatitis were all negative. In addition, she presented a picture of severe haemolytic anaemia resistant to several treatments and needed multiple transfusions. Twenty-three days after admission, the patient presented hepatic encephalopathy and received an orthotopic liver transplant on day 25. The evolution after transplantation was good and the patient continues in good health with no evidence of haemolysis almost 2 years later. Liver toxicity due to Nimesulide is well known, but to our knowledge the occurrence of haemolytic anaemia has not been related to this drug previously. For these reasons, Nimesulide has been restricted or removed from the market in several countries in recent months.

Abstract
Childhood is characterized by continuous growth and development during which the organs and systems gradually mature. Because drug pharmacokinetics and pharmacodynamics in children differ from those in adults, pediatric patients are highly susceptible to adverse drug reactions. Surprisingly, very few studies have been designed to study the efficacy and safety of drugs in this population and consequently dosage regimens are based on the assumption that children are small adults. We present a detailed review of these controversial aspects and propose the establishment of a multicenter, multidisciplinary network to monitor drug-induced liver disease in children. This project represents the integration of an epidemiological approach into routine clinical care. A protocol agreed by consensus for the collection of data on cases of hepatotoxicity with uniform and internationally accepted criteria for causality assessment and the classification of drug-induced liver injuries is proposed.

Abstract
BACKGROUND The role of silymarin in the treatment of liver cirrhosis is controversial. AIM Clinical outcome,biochemical profile and the antiperoxidative effects of silymarin MZ-80 during 6 months treatment were investigated in patients with alcoholic liver cirrhosis. METHODS Sixty consecutive patients with alcoholic liver cirrhosis were randomized to receive either silymarin MZ-80 (S) (150 mg t.i.d. per day) or placebo (P) for periods of 6 months. Erythrocyte total glutathione (GSH) content, platelet malondialdehyde (MDA) and serum amino-terminal propeptide of procollagen Type III (PIIINP) were determined at baseline and at the end of treatment. RESULTS Forty-nine patients completed the study (24 S and 25 P). The 2 groups were well-matched for demographic as well as baseline clinical and laboratory parameters. Silymarin increased total GSH at 6 months (4.5 +/- 3.4 to 5.8 +/- 4.0 micromol/g Hb) whereas, in the placebo group, GSH remained unchanged (4.1 +/- 3.9 to 4.4 +/- 4.1 micromol/gHb) (p < 0.001), and platelet-derived non-induced MDA decreased by 33% (p < 0.015). A parallel decrease in PIIINP values was seen with silymarin (1.82 1.03 to 1.36 +/- 0.5 U/ml, p < 0.033) but not with placebo (1.31 +/- 0.4 to 1.27 +/- 0.6 U/ml). There were no concurrent changes on laboratory indices of the pathology. CONCLUSIONS Silymarin is well-tolerated and produces a small increase in glutathione and a decrease in lipid peroxidation in peripheral blood cells in patients with alcoholic liver cirrhosis. Despite these effects no changes in routine liver tests were observed during the course of therapy.

Abstract
OBJECTIVE To analyze the characteristics of hepatotoxicity due to ticlopidine. PATIENTS AND METHODS We describe all the case of hepatotoxicity attributed to ticlopidine and reported to the Register of drug associated hepatopathies. We also obtained data from MEDLINE and the Spanish Medical Index regarding cases reported during the period 1982 2001. RESULTS We reported twelve cases of hepatopathy related to the use of ticlopidine. These made up 5% of all the cases notified to the Register. Eighty three percent of the patients were male, and of an average age of 68 years. Sixty six percent required hospital admission. The latent period varied between 2 and 13 weeks. The liver lesion was of cholestatic type in 75% of the cases, hepatocellular in 16.6% and mixed in 8.3%. Twenty five percent of the patients had received sub therapeutic doses. CONCLUSIONS Ticlopidine is often related to hepatotoxicity. This seems to be due to an idiosyncratic mechanism and is mainly cholestatic. The use of lower dosage than that recommended means that the desired therapeutic effect is not attained but does not protect against the development of hepatotoxicity. Doctors who use this drug should be aware of this so as to establish the true risk benefit relation.

Abstract
OBJECTIVE To evaluate the characteristics of flutamide induced hepatotoxicity. MATERIAL AND METHODS In this retrospective study we have analyzed all cases of flutamide hepatotoxicity submitted to the Andalucian Registry of drug-induced liver disease. Data were collected using a structured reporting form. Causality assessment was performed using two clinical scales: the standard CIOMS scale and the recently developed María and Victorino scale. RESULTS Nine of 185 patients (4.9%) were identified. In 8 male patients, mean age 75 years (range 65-83), flutamide was indicated for palliative therapy of disseminated prostatic carcinoma, and in one young female (14 years) was given for the treatment of facial hirsutism. The mean duration of the flutamide therapy was 151 days (range 4-443). All patients presented with overt liver injury, the most frequent features being asthenia, anorexia, weight loss, nausea, vomiting and jaundice. No patient showed hypersensitivity features. In two patients (22%) the hepatic damage evolved to fulminant liver failure, one of them undergoing a liver transplantation and the other subsequently died. An additional patient died of a non-hepatic related cause when his liver function was improving. Causality assessment by the two clinical scales did not exclude any case, but the two patients who died where classified as unlikely by the María and Victorino scale. CONCLUSIONS Flutamide can induce severe acute hepatitis, probably due to an idiosyncratic metabolic mechanism. Liver tests monitoring should probably be mandatory during the first months of flutamide therapy and the drug withdrawn if transaminases began to increase.

Abstract
This study was performed to compare the assessments of drug-induced liver injury obtained with 2 methods, the Council for International Organizations of Medical Sciences (CIOMS) scale and the recently validated Maria & Victorino (M&V) clinical scale, in cases submitted to a registry of hepatotoxicity. A total of 215 cases of hepatotoxicity reported with a structured reporting form were evaluated by 3 independent experts. Because of the use of multiple drugs, 228 ratings were generated. The probability of the diagnosis was classified as definitive, probable, possible, unlikely, or excluded, and evaluated for consistency with a weighted kappa statistical test. Absolute agreement between the 2 scales was observed in 42 cases (18%, weighted kappa 0.28) with disagreement of 1 level in 108 cases (47%), and of 2 levels in 70 cases (31%). The best correlation between the 2 scales was obtained for drug-induced liver injury involving a suggested immunoallergic mechanism: the disagreement was 1 level or less in 72% of the cases (34 of 48), compared with 60% of the cases (85 of 141) that involved a presumed idiosyncratic metabolic mechanism. The lowest agreement (6%) was observed in cases with evidence of cholestasis. No agreement was found in cases of fulminant hepatitis or death. The CIOMS scale showed better discriminative power and produced assessments closer to those of specialists. The performance of the M&V scale was poor in reactions with long latency periods (i.e., amoxycillin/clavulanic acid), evolution to chronicity after withdrawal (cholestatic pattern), or death.

Abstract
Liver injury induced by benzodiazepines is rare and is classified as an unpredictable or idiosyncratic hepatotoxic reaction. Early reports indicated that in most cases the pattern of liver injury was cholestatic. We describe three patients with persistent increases in liver transaminase levels after several weeks of treatment with bentazepam, a benzodiazepine marketed in Spain for anxiety disorders. In all cases withdrawal of the drug was followed by resolution of transaminase level abnormalities. A liver biopsy (done in one patient only) showed histological evidence of severe chronic active hepatitis. In conclusion, these findings, together with two previously published case reports, suggest that a benzodiazepine can cause chronic hepatitis and argue in favor of using liver function tests to monitor all patients taking bentazepam.

Abstract
BACKGROUND Interferon therapy has been shown to induce lipid abnormalities. AIM We assessed the effects of interferon-beta on the lipoprotein profile and post-heparin lipase activities in 26 normolipaemic patients with chronic hepatitis C. METHODS Interferon-beta was administered subcutaneously at doses of 6 x 106 U (units) three times a week, over 6 months, and lipoproteins and post-heparin lipases were measured at baseline and at the end of therapy. RESULTS Plasma triglycerides increased by 21% due to preferential enrichment in those contained in the very low density lipoprotein (VLDL) and low density lipoprotein (LDL) fractions. The concentration of cholesterol decreased slightly in the high density lipoprotein (HDL) subfractions. Lipoprotein lipase, but not hepatic lipase activity decreased by a 36%, and this change showed a significant negative correlation with changes in plasma triglycerides. Five patients (19.5%) responded to interferon-beta therapy. The lipoprotein profile was no different between responders and non-responders to therapy. CONCLUSIONS Interferon-beta treatment in normolipaemic patients with chronic hepatitis C induced moderate disturbances in plasma lipoproteins, associated with inhibition of lipoprotein lipase activity.

Abstract
BACKGROUND/AIM Ebrotidine is a new H2-receptor antagonist marketed in Spain in early 1997 and withdrawn in July 1998. We report 11 cases of acute liver injury related to ebrotidine and submitted to a Regional Registry of Hepatotoxicity between June 1997 and August 1998. METHODS In all cases a structured protocol was used to ascertain the role of ebrotidine and to exclude other causes (viral, immunologic, metabolic) of liver injury. RESULTS All patients showed clinical symptoms of acute hepatitis, with a marked increase in aminotransferase activities (ALT values ranging from 15 to 91 times the upper limit of normal). Total bilirubin values were also greatly increased (mean 16 mg/dl), and the liver injury was defined as hepatocellular. Features of hypersensitivity were absent. Liver biopsy was done in three patients. Histopathological examination revealed mainly centrozonal necrosis (two cases) or massive necrosis (one patient). Withdrawal of the drug was followed by a gradual improvement in liver dysfunction, except in one patient who developed fulminant hepatic failure and died. There was a positive response to rechallenge in one patient after an inadvertent drug administration. CONCLUSION Ebrotidine therapy seems to be associated with severe acute liver injury, and therefore its benefit/risk ratio is unfavorable. The relative rareness and unpredictability of the injury, the lack of dose-relationship and the absence of hallmarks of drug allergy are suggestive of an idiosyncratic metabolic mechanism.
