Abstract
Systemic lupus erythematosus (SLE) is a common multisystem disease characterised by a wide variety of presentation patterns and complex manifestations. As a lymphoid organ, the liver plays an important role in the immune response and is a target of autoimmune responses.1 SLE can affect the liver in approximately 25-60 % of patients during their disease course.2,3 Liver dysfunction and SLE can present with complicated differential diagnoses. Liver dysfunction in SLE is usually mild and rarely leads to advanced liver diseases such as cirrhosis and liver failure.4,5 Liver dysfunction in SLE is usually caused by non-SLE-related causes such as drug toxicity, fatty liver, alcoholism, and associated autoimmune hepatitis. However, primary liver involvement in SLE is also well-recognised. Patients with SLE who present with acute liver failure are rare. We report a rare case of SLE-associated acute severe liver injury along with a literature review.

Role of Altered Metabolism of Triglyceride-Rich Lipoprotein Particles in the Development of Vascular Dysfunction in Systemic Lupus Erythematosus. Biomolecules 2023; 13:biom13030401.

Abstract
Background: Impaired lipid metabolism contributes to accelerated inflammatory responses in addition to promoting the formation of atherosclerosis in systemic lupus erythematosus (SLE). We aimed to evaluate the lipid profile, inflammatory markers, and vascular diagnostic tests in active SLE patients to clarify the association between dyslipidemia and early vascular damage. Patients and Methods: 51 clinically active SLE patients and 41 age- and gender-matched control subjects were enrolled in the study. Lipoprotein subfractions were detected by Lipoprint. Brachial artery flow-mediated dilation and common carotid intima-media thickness were detected by ultrasonography. Arterial stiffness indicated by augmentation index (Aix) and pulse wave velocity was measured by arteriography. Results: We found significantly higher Aix, higher VLDL ratio, plasma triglyceride, ApoB100, and small HDL, as well as lower HDL-C, large HDL, and ApoA1 in patients with SLE. There was a significant positive correlation of Aix with triglyceride, VLDL, IDL-C, IDL-B, and LDL1. A backward stepwise multiple regression analysis showed IDL-C subfraction to be the best predictor of Aix. Conclusions: Our results indicate that in young patients with SLE, triglyceride-rich lipoproteins influence vascular function detected by Aix. These parameters may be assessed and integrated into the management plan for screening cardiovascular risk in patients with SLE.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease. Although gastrointestinal (GI) involvement is reported in the literature, GI manifestations of lupus are not common in the early disease course. GI symptoms can be related to several factors other than lupus; however, systemic lupus per se can be the responsible factor. Although the typical presentation is a gradual onset of progressive symptoms, acute abdominal pain is frequently reported and is the most serious presentation. It can reflect gastroenteritis, cholecystitis, hepatitis, pancreatitis, peritonitis, and abdominal vasculitis. When SLE diagnostic criteria for GI manifestations are lacking, the decision to implicate lupus as the cause of these manifestations is difficult, especially in the primary presentation. Early diagnosis and the initiation of immunosuppressive agents are associated with a better outcome. In this case, we introduce a patient who presented with acute abdominal pain secondary to acute liver failure as the first manifestation of lupus.

Abstract
HMG-CoA reductase inhibitors, or statins, are potent plasma LDL-cholesterol (LDL-c) lowering agents. Since the introduction of the first statin, lovastatin, in 1987, accumulating evidence showed that non-cholesterol lowering effects play an important role in their efficacy to reduce atherosclerotic cardiovascular disease (ASCVD). Thus, these non-LDL-c lowering properties could benefit patients with immune-mediated diseases. Statins and their associated immune-modulating roles have recently received much attention. Different statins have been administered in various experimental and clinical studies focused on autoimmunity. The results indicate that statins can modulate immune responses through mevalonate pathway-dependent and -independent mechanisms. The anti-inflammatory and immune-modulating effects include cell adhesion, migration of antigen presenting cells, and differentiation, as well as activation, of T-cells. In various autoimmune diseases (e.g. rheumatoid arthritis, lupus, and multiple sclerosis), promising results have been obtained to date.

Abstract
A 44-year-old Japanese woman was admitted to our hospital with fatigue and an altered liver function. She had been receiving atorvastatin treatment for 10 months. Although no jaundice was seen, the patient's serum alkaline phosphatase and γ-glutamyl transpeptidase levels were markedly elevated. Based on the results of a drug-induced lymphocyte-stimulation test, her liver disease was diagnosed as atorvastatin-induced hepatic injury. Subsequently, anti-mitochondrial antibodies (AMAs) were detected in her serum; however, a liver biopsy specimen did not show the characteristic features of primary biliary cholangitis. We herein report the detection of AMAs accompanied by drug-induced hepatic injury caused by atorvastatin.

Abstract
An 81-year-old woman developed liver dysfunction after two months' treatment with direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection. She was positive for serum anti-nuclear antibody, with an elevated immunoglobulin G level. A liver biopsy revealed high-grade interface hepatitis and infiltrate of lymphocytes and plasma cells. DAA-associated drug-induced autoimmune hepatitis (DI-AIH) was considered. Her liver dysfunction improved after discontinuing DAA therapy and starting prednisolone treatment. The differential diagnosis for AIH should include liver injury during DAA therapy for chronic HCV infection.

Abstract
Drug-induced lupus erythematosus (DILE) is a lupus-like illness that has been recognized as an entity under environmentally-induced lupus erythematosus, where other agents such as physical (ultra-violet irradiation), chemical (heavy metals, aromatic amines) and food products (alfalfa sprouts) have been implicated. DILE has been accepted as a side effect of therapy with over 80 drugs since its first description in association with sulfadiazine in 1945. The epidemiology and clinical course of SLE and DILE differ markedly and prognosis is generally favourable in the latter although occasional lifethreatening cases have been reported in the literature. Constant pharmacovigilance is crucial for prompt diagnosis and cessation of offending therapy offers the best outcome. This review discusses the clinical presentation, diagnosis of DILE as well as provides an update on postulated pathogenic mechanisms and an overview of implicated drugs.

An analysis of drug-induced liver injury, which showed histological findings similar to autoimmune hepatitis. J Gastroenterol 2016; 51:597-607.

Abstract
BACKGROUND Drug-induced liver injury (DILI) sometimes resembles autoimmune hepatitis (AIH) in its hepatic histology. However, there is lacking data of a comparison of the characteristics between such DILI and DILI without histological findings like AIH. METHODS We enrolled 62 patients with DILI who were diagnosed using the Roussel Uclaf Causality Assessment Method, and performed a liver biopsy. These patients were classified into two groups: DILI with histology like AIH (group A, n = 23) and DILI without such histology (group B, n = 39). Sixteen patients of group A could be further classified into two groups: patients with relapse of the liver injury (group C, n = 8) and without relapse (group D, n = 8), after the recovery of the DILI. We compared the clinical and histological findings between group A and B, and group C versus D. RESULTS Group A was characterized by an older age (p = 0.043), higher immunoglobulin G level (p = 0.017), positive antinuclear antibody status (p = 0.044), and a higher frequency of complementary alternative medicines and Chinese herbal medicines as the causative drug (p = 0.008). There were no significant differences between group C and D regarding the clinical data and liver histological findings. CONCLUSIONS The clinical characteristics of DILI, which showed histological findings similar to AIH, were revealed. In such patients, a liver biopsy is recommended in order to determine the appropriate treatment strategy. In DILI with histology like AIH patients, long-term follow-up is needed to perceive the relapse.

Abstract
A 60-year-old woman was admitted to our hospital with non-coma acute liver failure. Based on a 1-month history of supplement use, negative viral hepatitis markers, positive antinuclear antibody test, high IgG level, positive HLA-DR4, liver biopsy findings of centrizonal necrosis, and inflammatory cell infiltration in the portal area, she was diagnosed with drug-induced liver injury (DILI) with autoimmune features or the acute hepatitis phase of autoimmune hepatitis (AIH). Although her liver disorder was ameliorated by administration of prednisolone and plasma exchange, anemia and thrombocytopenia were observed during the course of treatment. A bone marrow examination showed hemophagocytosis. Therefore, with no other evidence suggesting infection or malignancy, we determined that the patient had DILI complicated by hemophagocytic syndrome (HPS). Although HPS is very rarely seen in patients with DILI with autoimmune features or the acute hepatitis phase of AIH, this condition should be considered if cytopenia is observed in a patient with DILI.

Abstract
Background & Aims Occasional risk of serious liver dysfunction and autoimmune hepatitis during atorvastatin therapy has been reported. We compared the risk of hepatotoxicity in atorvastatin relative to simvastatin treatment. Methods The UK GPRD identified patients with a first prescription for simvastatin [164,407] or atorvastatin [76,411] between 1997 and 2006, but with no prior record of liver disease, alcohol-related diagnosis, or liver dysfunction. Incident liver dysfunction in the following six months was identified by biochemical value and compared between statin groups by Cox regression model adjusting for age, sex, year treatment started, dose, alcohol consumption, smoking, body mass index and comorbid conditions. Results Moderate to severe hepatotoxicity [bilirubin >60μmol/L, AST or ALT >200U/L or alkaline phosphatase >1200U/L] developed in 71 patients on atorvastatin versus 101 on simvastatin. Adjusted hazard ratio [AHR] for all atorvastatin relative to simvastatin was 1.9 [95% confidence interval 1.4–2.6]. High dose was classified as 40–80mg daily and low dose 10–20mg daily. Hepatotoxicity occurred in 0.44% of 4075 patients on high dose atorvastatin [HDA], 0.07% of 72,336 on low dose atorvastatin [LDA], 0.09% of 44,675 on high dose simvastatin [HDS] and 0.05% of 119,732 on low dose simvastatin [LDS]. AHRs compared to LDS were 7.3 [4.2–12.7] for HDA, 1.4 [0.9–2.0] for LDA and 1.5 [1.0–2.2] for HDS. Conclusions The risk of hepatotoxicity was increased in the first six months of atorvastatin compared to simvastatin treatment, with the greatest difference between high dose atorvastatin and low dose simvastatin. The numbers of events in the analyses were small.

Abstract
AIM: To identify the clinical characteristics of lipid-lowering agents-induced autoimmune hepatitis (AIH).
METHODS: The clinical data for patients with lipid-lowering agents-induced AIH were retrieved from Chinese Biomedical Database, VIP Medical information resource system and PubMed (January 1983 to October 2014) to conduct a systematic review.
RESULTS: Multiple lipid-lowering agents could induce AIH. A total of 14 cases due to 7 kinds of drugs were identified, and 64.3% (9/14) of the patients were females. No significant differences were found in clinical manifestations or liver histology compared to sporadic AIH, and lipid-lowering agents-induced AIH patients might have extrahepatic manifestations such as systemic lupus erythematosus and rhabdomyolysis. Different statins might have cross-toxicity, liver injury with a shorter latency period and more serious symptoms could occur when other statins were reused. Discontinuation of offending drugs was the essential treatment when the diagnosis was established; however, liver function in 6 patients was even worse although the drugs were stopped and 28.6% (4/14) of the patients finally developed cirrhosis. Immunosuppressive therapy was needed in 92.9% (13/14) of patients. Most patients responded well and the liver function was gradually improved, while antinuclear antibody titer might also significantly decrease and even turn negative. Long-term immunosuppressive therapy was not needed generally because relapse seldom occurred.
CONCLUSION: Different characteristics can be found in lipid-lowering agents-induced AIH patients compared to sporadic AIH patients. Liver function and antinuclear antibody tests with intensive follow-up may promote an immediate diagnosis and treatment.

Abstract
INTRODUCTION Drug-induced lupus (DIL) refers to an idiosyncratic side effect of numerous, apparently unrelated, medications, in which symptoms overlap with those of systemic lupus erythematosus. DIL is reversible by discontinuation of the medication. The etiological mechanism underlying DIL is linked to the inherent susceptibility of the adaptive immune system to lapse into auto-reactivity. AREAS COVERED Clinical and laboratory features of DIL will be compared with those of idiopathic systemic lupus and with other types of drug reactions with overlapping features. Formerly commonly-used drugs conferred very high risk of developing DIL, although the probability of developing DIL has not been established with most lupus-inducing drugs. Pharmacological or physiochemical properties of the parent compounds are uninformative, but the importance of reactive drug metabolites in initiating autoimmunity will be discussed. As with most systemic autoimmune diseases, the pathogenesis of DIL is complex and obscure. The role of complement and human leukocyte allotypes as well as drug acetylator phenotype inform the underlying mechanism, and several of these non-mutually exclusive concepts will be described. EXPERT OPINION The pros and cons of proposed mechanisms for DIL will be discussed in the context of current understanding of autoimmunity and immune tolerance to self.

Pastori D, Polimeni L, Baratta F, Pani A, Del Ben M, Angelico F. The efficacy and safety of statins for the treatment of non-alcoholic fatty liver disease. Dig Liver Dis 2015; 47:4-11. [PMID: 25224698 DOI: 10.1016/j.dld.2014.07.170] [Citation(s) in RCA: 103] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2014] [Revised: 07/18/2014] [Accepted: 07/24/2014] [Indexed: 12/11/2022]
Abstract
Non-alcoholic fatty liver disease is an emerging liver disease in Western countries and the most frequent cause of incidental elevation of serum liver enzymes. Dyslipidaemia is frequently observed in patients with non-alcoholic fatty liver disease, and treatment of dyslipidaemia plays a critical role in the overall management of these patients. Moreover, coronary artery disease remains the most common cause of death. Statins are effective lipid-lowering agents, associated with a lowering the risk of cardiovascular events in several interventional randomized clinical trials. However, statins are often underused in patients with non-alcoholic fatty liver disease and many physicians are concerned about the prescription of statins to patients with unexplained persistent elevation of liver enzymes or active liver disease. Based on currently available data, statin therapy, at low-to-moderate doses, seems to be safe and has low liver toxicity. Treatment of dyslipidaemia in patients with non-alcoholic fatty liver disease is recommended and may also improve liver function tests. In these patients, the risks of not taking statins could outweigh the risks of taking the drug. Conversely, the usefulness of statins for the treatment of non-alcoholic fatty liver disease/non-alcoholic steatohepatitis is still a matter of debate and randomized clinical trials of adequate size and duration are required.

Abstract
Approximately 95% of statin-treated patients tolerate this form of cholesterol management without any adverse effects. However, given their efficacy in reducing low density lipoproteins and cardiovascular events large numbers of patients are selected for statin therapy. Therefore muscle complications are, in fact, quite common. Limited understanding of the underlying pathophysiology has hampered physicians' ability to identify patients at risk for developing statin myotoxicity. A growing number of published case reports/series have implicated statins in the exacerbation of both acquired and genetic myopathies. A clinical management algorithm is presented which outlines a variety of co-morbidities which can potentiate the adverse effects of statins on muscle. In addition, a rational approach to the selection of those patients most likely to benefit from skeletal muscle biopsy is discussed. Ongoing work will define the extent to which statin-intolerant patients represent carriers of recessive metabolic myopathies or pre-symptomatic acquired myopathies. The expanding importance of pharmacogenomics will undoubtedly be realized in the field of statin myopathy research within the next few years. Such critical information is needed to establish more definitive management and diagnostic strategies.

Abstract
Drug-induced lupus erythematosus is defined as a syndrome with clinical and serological features similar to systemic lupus erythematosus that is temporally related to continuous drug exposure and which resolves after discontinuation of this drug. More than 90 drugs, including biological modulators such as tumour necrosis factor-α inhibitors and interferons, have been identified as likely ‘culprits’. While there are no standard diagnostic criteria for drug-induced lupus erythematosus, guidelines that can help to distinguish drug-induced lupus erythematosus from systemic lupus erythematosus have been proposed and several different patterns of drug-induced lupus erythematosus are emerging. Distinguishing drug-induced lupus erythematosus from systemic lupus erythematosus is important because the prognosis of drug-induced lupus erythematosus is usually good when the drug is withdrawn. This review discusses the differences between drug-induced lupus erythematosus and systemic lupus erythematosus, the mechanisms of action of drug-induced lupus erythematosus and drugs that are usually associated with drug-induced lupus erythematosus, with particular focus on the biological treatments.

Abstract
Autoimmune hepatitis is a disease of the hepatic parenchyma that can present in acute or chronic forms. In common with many autoimmune diseases, autoimmune hepatitis is associated with non-organ-specific antibodies in the context of hepatic autoimmunity. This dichotomy has made definition of a unifying hypothesis in the pathophysiology of the disease difficult, although data from the past 8 years have drawn attention to the role of regulatory T cells. Several triggers have been identified, and the disease arises in genetically susceptible individuals. Clinical and biochemical remission is achievable in up to 85% of cases. For the remaining patients, alternative immunosuppression strategies are an option. Liver transplantation provides an excellent outcome for patients with acute liver failure or complications of end-stage liver disease, including hepatocellular carcinoma. Variant or overlapping syndromes are worthy of consideration when unexpected disease features arise.

Abstract
Drug-induced autoimmune hepatitis (DIAIH) has been reported to be caused by many drugs, which possesses the characteristics of both drug-induced liver injury (DILI) and autoimmune hepatitis (AIH). A better understanding of the epidemiology, pathogenesis, pathology and clinical symptoms of DIAIH can help us better diagnose and treat this disease.

Abstract
PURPOSE OF REVIEW Autoimmune hepatitis (AIH) is a chronic, progressive hepatitis of uncertain cause which has fluctuating activity characterized by periods of flares and remissions. Initial placebo-controlled trials carried out in the 1970s demonstrated that immunosuppression with steroids was extremely effective in reducing flares and progression of disease. The late 1980s-1990s could be described as the 'Dark Ages' of AIH treatment research. Very few clinical studies were performed during this time, although it became increasingly apparent that not all patients tolerated or responded to traditional immunosuppression, and that not all patients were easy to diagnose because of overlapping features with other autoimmune conditions. Fortunately, clinical research in the treatment of AIH has experienced a renaissance in the 21st century. RECENT FINDINGS This review highlights some of the more important recent discoveries, including the creation of the clinically useful short form of the autoimmune hepatitis diagnostic scoring system; accumulation of data supporting the use of mycophenolate and tacrolimus as second-line treatment; and the recent completion of the largest, double-blind, placebo-controlled trial of AIH treatment to date, comparing budesonide to prednisone. SUMMARY These new findings are pertinent to the everyday clinical management of patients with AIH.

Abstract
The clinical phenotype of classical autoimmune hepatitis can be mimicked by idiosyncratic drug-induced liver injury, and differentiation can be difficult. The goals of this review are to enumerate the major agents of drug-induced autoimmune-like hepatitis, describe the clinical findings and risk factors associated with it, detail the clinical tools by which to assess causality, discuss putative pathogenic mechanisms, and describe treatment and outcome. The frequency of drug-induced autoimmune-like hepatitis among patients with classical features of autoimmune hepatitis is 9%. Minocycline and nitrofurantoin are implicated in 90% of cases. Female predominance, acute onset, and absence of cirrhosis at presentation are important clinical manifestations. Genetic factors affecting phase I and phase II transformations of the drug, polymorphisms that protect against cellular oxidative stress, and human leukocyte antigens that modulate the immune response may be important pathogenic components. Clinical judgment is the mainstay of diagnosis as structured diagnostic methods for drug-induced liver injury are imperfect. The covalent binding of a reactive drug metabolite to a hepatocyte surface protein (commonly a phase I or phase II enzyme), formation of a neoantigen, activation of CD8 T lymphocytes with nonselective antigen receptors, and deficient immune regulatory mechanisms are the main bases for a transient loss of self-tolerance. Discontinuation of the offending drug is the essential treatment. Spontaneous improvement usually ensues within 1 month. Corticosteroid therapy is warranted for symptomatic severe disease, and it is almost invariably effective. Relapse after corticosteroid withdrawal probably does not occur, and its absence distinguishes drug-induced disease from classical autoimmune hepatitis.

Abstract
Drug-induced lupus (DIL) is syndrome characterised by the occurrence of lupus-like symptoms and serological findings, following exposure to certain drugs. A substantial number of drugs can induce the positivity of antinuclear antibodies (ANA) but the diagnosis of DIL cannot be done in the absence of clinical features. Most patients with DIL have constitutional symptoms, arthralgia or occasionally arthritis, myalgias, fever and weight loss. These features may take weeks or months to develop and use to be mild with renal and central nervous system happening very rarely. ANA are always positive. They are mainly anti-histone proteins. Antibodies to ds-DNA are a rare finding and would tend to favour a diagnosis of idiopathic SLE. They have been associated with the use of tumour necrosis factor inhibitors (ant-TNF) and minocycline. Some drugs can induce particular symptoms o serological abnormalities and the diagnosis may be more difficult. It is the case of minocycline-induced lupus, which uses to affect young women with anti-ds-DNA and p-ANCA antibodies positive and negative anti-histone antibodies. Treatment with anti-TNF alpha is frequently associated with the development of ANA and anti-DNA. The incidence of ANA positive varies between 23-57% and anti-DNA between 9-33%. However, only a small number of patients will develop DIL or vasculitis. Resolution or marked improvement of the symptoms generally occurs within 2-5 weeks of the drugs withdrawal although some patients may require non-steroid anti-inflammatory drug or low dose steroid. Immunosuppressive drugs may be needed in severe cases with renal or neurological involvement. Some patients remain ANA positive for long periods of time. No treatment is necessary for ANA positive in the absence of clinical features.

Acute hepatitis caused by a natural lipid-lowering product: when "alternative" medicine is no "alternative" at all. J Hepatol 2009; 50:1273-7.

Abstract
BACKGROUND/AIMS The general public's growing mistrust of the pharmaceutical industry and its perception of the lack of adverse effects of "natural" therapy have lead to the increasing use of "alternative drugs" for hypercholesterolemia. METHODS A sixty-three year old woman presented with severe hypertransaminasemia that had developed progressively over a few weeks. For six months she had been taking Equisterol, an over-the-counter lipid-lowering product containing guggulsterol and red yeast rice extract. The product had been prescribed for hypercholesterolemia because the patient had developed hepatotoxicity while on lovastatin. RESULTS Liver biopsy revealed severe lobular necroinflammatory changes with an eosinophilic infiltrate. The episode was regarded as an adverse drug reaction after exclusion of other possible causes of acute liver disease and the prompt normalization of liver function tests after Equisterol had been discontinued. Red yeast rice extract's cholesterol-lowering properties are largely due to fungal metabolites known as monacolins, one of which--monacolin K--is identical to lovastatin. CONCLUSIONS The choice of an alternative medicine approach in this case subjected the patient to "re-challenge" with the official medicine agent that had previously caused mild hepatotoxicity. Physicians should keep in mind that "alternative" medicine is not always the safest alternative and sometimes it is not even "alternative."

Abstract
Autoimmune hepatitis is a chronic liver disease, and both genetic background and environmental factors are related to its pathogenesis. Here, we report that out of five members of a family with similar human leukocyte antigen haplotypes, two developed autoimmune hepatitis, one was positive for antinuclear antibody, and the remaining two had no features of autoimmunity. The two patients with autoimmune hepatitis had a history of medication use, whereas the other family members did not. Our familial study suggests that in addition to genetic background, medication use and other environmental factors may be related to the onset of autoimmune hepatitis.

Abstract
A 50-year-old woman was admitted for active rheumatoid arthritis (RA). She was found to have RA 1 year prior to this admission. Past history was unremarkable and she had no family history for rheumatic diseases. As nonsteroidal anti-inflammatory drug (NSAID) and methotrexate were not effective, etanercept was started (25 mg, twice a week). Mild elevation of alanine transaminase (ALT) and aspartate transaminase (AST) was found as an outpatient, and it was considered to be NSAID-induced liver injury. Two weeks after the first dose of etanercept, she developed progressive elevation of AST and ALT with right upper quadrant tenderness and hepatomegaly. Etanercept was discontinued and liver biopsy was performed, which demonstrated portal-area-dominant lymphoplasmacytic inflammatory cell infiltration. She was diagnosed as autoimmune hepatitis (AIH). Glucocorticoid was started with normalized liver function and stable joint symptoms. AIH was thought to be acutely aggravated by the administration of etanercept.

Abstract
Drug-induced lupus (DIL) is a lupus-like illness that has been recognized as a side effect of over 80 drugs since its first description in association with sulfadiazine in 1945. The epidemiology and clinical course of idiopathic systemic lupus erythematosus and DIL differ markedly, and prognosis is generally favorable in the latter although occasional life-threatening cases have been reported in the literature. Constant pharmacovigilance is crucial for prompt diagnosis and cessation of offending therapy, hence achieving the best outcome. This review discusses the clinical presentation, diagnosis and treatment of DIL so as to call for vigilance of medical workers.

Abstract
HMG-CoA reductase inhibitors (statins) are a widely used class of drug, and like all medications, have potential for adverse effects (AEs). Here we review the statin AE literature, first focusing on muscle AEs as the most reported problem both in the literature and by patients. Evidence regarding the statin muscle AE mechanism, dose effect, drug interactions, and genetic predisposition is examined. We hypothesize, and provide evidence, that the demonstrated mitochondrial mechanisms for muscle AEs have implications to other nonmuscle AEs in patients treated with statins. In meta-analyses of randomized controlled trials (RCTs), muscle AEs are more frequent with statins than with placebo. A number of manifestations of muscle AEs have been reported, with rhabdomyolysis the most feared. AEs are dose dependent, and risk is amplified by drug interactions that functionally increase statin potency, often through inhibition of the cytochrome P450 3A4 system. An array of additional risk factors for statin AEs are those that amplify (or reflect) mitochondrial or metabolic vulnerability, such as metabolic syndrome factors, thyroid disease, and genetic mutations linked to mitochondrial dysfunction. Converging evidence supports a mitochondrial foundation for muscle AEs associated with statins, and both theoretical and empirical considerations suggest that mitochondrial dysfunction may also underlie many nonmuscle statin AEs. Evidence from RCTs and studies of other designs indicates existence of additional statin-associated AEs, such as cognitive loss, neuropathy, pancreatic and hepatic dysfunction, and sexual dysfunction. Physician awareness of statin AEs is reportedly low even for the AEs most widely reported by patients. Awareness and vigilance for AEs should be maintained to enable informed treatment decisions, treatment modification if appropriate, improved quality of patient care, and reduced patient morbidity.

Abstract
Conditions exhibiting features of two different autoimmune liver diseases are commonly designated overlap syndromes, although there is no current agreement on what constitutes an overlap syndrome or specific diagnostic criteria. As in the classic autoimmune liver diseases, such as autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC), the etiology is unknown but presumed to be related to alterations of immune regulation. Distinction of these clinical entities is important for management as outcomes may differ from outcomes of patients with diagnosis of classic autoimmune liver diseases. Due to their presumed rarity, no large therapeutic trials are available and treatment of overlap conditions is empirical and based upon extrapolation of data from the primary autoimmune liver diseases. PBC-AIH overlap is the most frequently described overlap syndrome and may be associated with a poor prognosis. This may represent an important and unrecognized cause of resistance to ursodeoxycholic acid in patients with PBC. PSC-AIH overlap is less commonly reported. Prognosis may be better than in patients with PSC alone; however, worse than in patients with AIH alone. Further studies are needed for determining diagnosis, natural history and optimal therapeutic strategies of overlap syndromes of autoimmune liver disease.

Abstract
The effort to reduce cardiovascular risk factors, including hyperlipidemia, has led to the increased use of lipid-lowering agents. Hyperlipidemic patients often have underlying fatty liver disease, however, and thus may have elevated and fluctuating liver biochemistries. Therefore, caution should be applied before attributing elevated liver tests to lipid-lowering agents. Data indicate that patients who have chronic liver disease and compensated cirrhosis should not be precluded from receiving statins to treat hyperlipidemia. Several recent studies and expert opinion currently fully endorse statin use in patients who have nonalcoholic fatty liver disease and other chronic liver disease if clinically indicated.

Abstract
BACKGROUND Drug toxicity is the leading cause of acute liver failure in the United States. Further understanding of hepatotoxicity is becoming increasingly important as more drugs come to market. AIMS (i) To provide an update on recent advances in our understanding of hepatotoxicity of select commonly used drug classes. (ii) To assess the safety of these medications in patients with pre-existing liver disease and in the post-liver transplant setting. (iii) To review relevant advances in toxicogenomics which contribute to the current understanding of hepatotoxic drugs. METHODS A Medline search was performed to identify relevant literature using search terms including 'drug toxicity, hepatotoxicity, statins, thiazolidinediones, antibiotics, antiretroviral drugs and toxicogenomics'. RESULTS Amoxicillin-clavulanic acid is one of the most frequently implicated causes of drug-induced liver injury worldwide. Statins rarely cause clinically significant liver injury, even in patients with underlying liver disease. Newer thiazolidinediones are not associated with the degree of liver toxicity observed with troglitazone. Careful monitoring for liver toxicity is warranted in patients who are taking antiretrovirals, especially patients who are co-infected with hepatitis B and C. Genetic polymorphisms among enzymes involved in drug metabolism and HLA types may account for some of the differences in individual susceptibility to drug hepatotoxicity. CONCLUSIONS Drug-induced hepatotoxicity will remain a problem that carries both clinical and regulatory significance as long as new drugs continue to enter the market. Future results from ongoing multicentre collaborative efforts may help contribute to our current understanding of hepatotoxicity associated with drugs.

Abstract
BACKGROUND/AIMS The aetiology of drug-induced liver injuries (DILI) in Asia is different from that in the West, as anecdotal studies have shown that traditional complementary and alternative medicines (CAM) accounted for a major proportion of offending drugs in DILI in Asia. We aimed to study DILI in Asia prospectively, and to test whether DILI caused by traditional CAM was related to adulterants. METHODS A collaborative group consisting of a tertiary-hospital hepatology department, a pharmaceutical laboratory, and a pharmacovigilance unit was formed to study patients with DILI at a tertiary hospital over a 26-month period prospectively. Traditional medicines that were implicated were tested for the presence of adulterants. RESULTS Thirty-one patients with DILI were enrolled: age 51+/-3 (18-79) years, 17 (55%) male. Twenty-three (74%) had hepatocellular, six (19%) had cholestatic, and two (7%) had a mixed pattern of injury. Chinese traditional CAM was the most common medication type implicated, accounting for 17 (55%) patients, followed by Malay CAM in five (16%). Thirty-one traditional medicines from 17 patients were available for chemical analysis. Adulterants were found in nine (29%) of them. CONCLUSIONS DILI in Asia has a different aetiology as compared with the West, and could be related to presence of adulterants in traditional CAM.

Abstract
BACKGROUND Statins have been increasingly associated with drug-induced autoimmune reactions, including lupus erythematosus. OBJECTIVE To identify and determine the clinical and biological characteristics of statin-induced autoimmune reactions. MATERIAL AND METHODS The MEDLINE database (1966 to September 2005) was used to identify all reported cases of statin-induced autoimmune diseases. The keywords used were statins, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, adverse effects, autoimmune disease, lupus erythematosus, dermatomyositis and polymyositis. RESULTS Twenty-eight cases of statin-induced autoimmune diseases have been published so far. Systemic lupus erythematosus was reported in 10 cases, subacute cutaneous lupus erythematosus in three cases, dermatomyositis and polymyositis in 14 cases and lichen planus pemphigoides in one case. Autoimmune hepatitis was observed in two patients with systemic lupus erythematosus. The mean time of exposure before disease onset was 12.8+/-18 months; range 1 month-6 years. Systemic immunosuppressive therapy was required in the majority of cases. In many patients, antinuclear antibodies were still positive many months after clinical recovery. A lethal outcome has been recorded in two patients despite aggressive immunosuppressive therapy. CONCLUSION Long-term exposure to statins may be associated with drug-induced lupus erythematosus and other autoimmune disorders. Fatal cases have been reported despite early drug discontinuation and aggressive systemic immunosuppressive therapy.

Abstract
Although the cause of autoimmune hepatitis (AIH) is unknown, drugs are believed to be potential triggers in some patients. In isolated case reports, statins have been considered such triggers. Here we describe 3 patients in whom it is probable that statins initiated the development of AIH. Two men (aged 47 and 51) and one woman (aged 57) developed AIH after the initiation of statin therapy. They developed positive titers of antinuclear antibodies, antismooth muscle antibodies (1/40 to 1/160), and hypergammaglobulinemia. Features of all 3 patients met the criteria for AIH according to the International Autoimmune Hepatitis Panel. Liver biopsies in all 3 showed varying stages of fibrosis and plasma cell infiltration, compatible with AIH. The woman developed hepatitis due to statins on 2 separate occasions: the first in 1999, due to simvastatin, and the second in 2001 to 2002, due to atorvastatin, which was severe and persisted even after discontinuing medication. Similarly, in the 2 other cases, exposure to statins preceded development of AIH, which persisted despite discontinuing medications. All 3 patients responded well to prednisone and azathioprine or mycophenolate therapy. 3 similar previously reported cases are reviewed. We conclude that the 3 cases reported here and 3 similar previously reported cases, indicate that severe, ongoing AIH on rare occasions can be triggered by statins.

Abstract
This case describes a young girl with Graves' disease, who presented with fulminant hepatic failure 9 months into propylthiouracil (PTU) therapy. Her clinical presentation was consistent with 'probable autoimmune hepatitis,' as defined by the International Autoimmune Hepatitis Group scoring system. Despite discontinuation of PTU and high-dose steroid therapy, she required liver transplantation. Subsequent pathology could not definitively rule out autoimmune hepatitis. PTU is an important cause of drug-related liver failure in children, and clinicians should be mindful that it is frequently used in patients who already have an underlying risk of autoimmune liver disease.

Abstract
The 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, or statin drugs, have been studied in numerous controlled human research trials involving hundreds of thousands of study participants. Statins have been prescribed for millions of patients. Based on this vast research and clinical experience, statins have been shown to improve lipid blood levels and reduce atherosclerotic coronary artery disease (CAD) risk, resulting in reduced CAD morbidity and mortality, and in several studies, reduced overall ("all-cause") mortality. From a safety perspective, both research trial evidence and clinical practice experience have demonstrated that statins are generally well tolerated. However, as with all pharmaceuticals, safety considerations exist with both monotherapy and combination statin therapy, mainly involving potential adverse effects on muscle, liver, kidney, and the nervous system. The evidence supporting statin-related potential adverse experiences on these organ systems is sometimes strong and based on clear clinical trial evidence (such as the increased risk of muscle enzyme elevation with higher statin doses). The evidence is at other times more speculative, being based on case reports and inconclusive clinical trial data (such as possible favorable or unfavorable effects of statins on cognition). Because the use of statins is so widespread, it is useful for the clinician to understand statin safety issues and the level of available evidence supporting the contention that various adverse effects are caused by statins. This review presents an assessment of statin safety based on an overview of the current statin safety data and their clinical implications.

Abstract
Idiosyncratic drug induced liver injury (DILI) remains poorly understood. It is assumed that the affected individuals possess a rare combination of genetic and non genetic factors that, if identified, would greatly improve understanding of the underlying mechanisms. This single topic conference brought together basic scientists, translational investigators, and clinicians with an interest in DILI. The goal was to define high priority areas of investigation that will soon be made possible by The Drug-Induced Liver Injury Network (DILIN). Since 2004 DILIN has been collecting clinical data, genomic DNA and some tissues from patients who have experienced bone fide DILI. The presentations spanned many different areas of DILI, and included novel data concerning mechanisms of hepatotoxicity, new "omics" approaches, and the challenges of improving causation assessment.

Abstract
Atherosclerosis is a progressive, lifelong condition that is the leading cause of death among middle-aged and elderly individuals aged > or =65 years. Up to 80% of elderly patients are found to have evidence of obstructive coronary heart disease at autopsy. Demographic trends, including the advancing median age and life expectancy of Western societies, suggest that a large share of the burden of atherosclerotic plaque is likely to be borne by elderly individuals. These trends are in part due to increases in a number of chronic diseases associated with adverse cardiovascular outcomes, including metabolic syndrome, diabetes mellitus and chronic kidney disease. Because the elderly have a higher attributable risk of coronary heart disease as a result of hypercholesterolaemia, more coronary deaths and overall events can be prevented via treatment in this age group compared with younger persons with hypercholesterolaemia. The efficacy, safety and tolerability of HMG-CoA reductase inhibitors (statins) have been confirmed in randomised, controlled, multicentre trials involving large numbers of patients aged > or =65 years. Although muscle symptoms such as myalgia are relatively common adverse events, more severe signs of myolysis such as myopathy and rhabdomyolysis are rare, but their risk is elevated by conditions (e.g. concomitant medications) that increase the systemic exposure of these agents. Statins differ in their susceptibility to increases in systemic exposure, but most statins have been demonstrated to be well tolerated and safe when administered to elderly patients. These favourable clinical findings should help clinicians counter highly prevalent 'ageism' bias in statin prescribing, whereby elderly patients, particularly those at highest cardiovascular risk, are often denied the benefits of statins without any meaningful foundation.

Abstract
Gastrointestinal (GI) manifestations of systemic lupus erythematosus (SLE) are protean. Any part of the GI tract and the hepatobiliary system can be involved. Up to two-third of SLE patients develop GI symptoms at some stage of their illnesses. Clinical presentations of GI lupus are non-specific and can be difficult to differentiate from infective, thrombotic, therapy-related and non-SLE etiologies. Clinical acumen and appropriate endoscopic, biopsy and imaging procedures are essential for establishing the correct diagnosis. Acute abdominal pain in SLE patients can herald an intra-abdominal catastrophe and should be evaluated promptly. Surgical intervention should be instituted without delay if conservative management fails or when there is clinical or radiological suspicion of visceral perforation or intra-abdominal collections.

Abstract
Autoimmune hepatitis (AIH) is an intermittently progressive liver disease characterized by hypergammaglobulinemia, autoantibodies, predominately periportal hepatitis, and a favorable response to corticosteroid therapy in most cases. There are no pathognomonic markers of autoimmune liver disease; rather, the diagnosis must be based on the presence of a constellation of characteristic clinical, laboratory, and histologic features in patients without other causes of such liver pathology. Although prednisone or prednisolone are the mainstays in initial therapy of AIH, azathioprine or other drugs with similar immunosuppressive mechanisms are of benefit for steroid-sparing effects or for use as monotherapy to maintain long-term remission. A fraction of patients meeting diagnostic criteria for AIH remains in long-term remission following withdrawal of immunosuppressive therapies, but in most patients, this disease represents a chronic condition requiring life-long monitoring and therapy.

Abstract
INTRODUCTION The toxic myopathy caused by statins (HMG-CoA reductase inhibitors) is well established. Recent reports add to these effects systemic immune diseases including systemic lupus erythematosus, vasculitis, polymyositis or dermatomyositis. EXEGESIS We report a case of dermatomyositis in a 69-year-old patient treated with pravastatin [Elisor]. She presented with typical features of dermatomyositis 2 years after she started a treatment with pravastatin. The treatment was discontinued and she slowly improved, with a transient dermocorticosteroid treatment. Eight other patients with dermatomyositis and chronic treatment with HMG-CoA reductase inhibitors are reported in the literature. All of them presented with classical features of dermatomyositis. The discontinuation of the treatment was followed by spontaneous clinical and biological improvement in 3/9 patients. The other patients received high doses of corticosteroids and improved, except one patient who died of respiratory failure (pulmonary fibrosis) despite the adjunction of oral cyclophosphamide [Endoxan]. In these patients, dermatomyositis can be considered as a severe adverse reaction to HMG-CoA reductase inhibitors although a distinct casual link cannot be definitely established. CONCLUSION The increasing prescription of statins has led to the parallel increment of reported side-effects, where autoimmune diseases are now described. Among them, our case of dermatomyositis in a patient receiving pravastatin adds to the eight reported cases in the literature and highlights the potential role of statins as triggers of immune systemic diseases.

Abstract
Statins were developed for the treatment of lipid disorders and have been proved to reduce cardiovascular morbidity and mortality when used for primary or secondary prevention. Beneficial effects in patients with osteoporotic fractures or rheumatoid arthritis (RA) have been suggested but remain unproven. Cardiovascular morbidity and mortality are increased in patients with RA or systemic lupus erythematosus, who should undergo serum lipid assays. When these show dyslipidemia, statin therapy should be started according to current recommendations.
