reliability of causality assessment for drug herbal and dietary supplement hepatotoxicity in the drug induced liver injury network dilin
Liver International, 2015Co-Authors: Paul H Hayashi, Huiman X Barnhart, Robert J Fontana, Rajender K Reddy, Naga Chalasani, Timothy J Davern, Jayant A Talwalkar, Andrew Stolz, Jay H Hoofnagle, Don C RockeyAbstract:Background & Aims Because of the lack of objective tests to diagnose drug-induced liver injury (DILI), causality assessment is a matter of debate. Expert opinion is often used in research and industry, but its test–retest reliability is unknown. To determine the test–retest reliability of the expert opinion process used by the Drug-Induced Liver Injury Network (DILIN). Methods Three DILIN hepatologists adjudicate suspected hepatotoxicity cases to one of five categories representing levels of likelihood of DILI. Adjudication is based on retrospective assessment of gathered case data that include prospective follow-up information. One hundred randomly selected DILIN cases were re-assessed using the same processes for initial assessment but by three different reviewers in 92% of cases. Results The median time between assessments was 938 days (range 140–2352). Thirty-one cases involved >1 agent. Weighted kappa statistics for overall case and individual agent category agreement were 0.60 (95% CI: 0.50–0.71) and 0.60 (0.52–0.68) respectively. Overall case adjudications were within one category of each other 93% of the time, while 5% differed by two categories and 2% differed by three categories. Fourteen per cent crossed the 50% threshold of likelihood owing to competing diagnoses or atypical timing between drug exposure and injury. Conclusions The DILIN expert opinion causality assessment method has moderate interobserver reliability but very good agreement within one category. A small but important proportion of cases could not be reliably diagnosed as ≥50% likely to be DILI.

liver injury from herbals and dietary supplements in the u s drug induced liver injury network
Hepatology, 2014Co-Authors: Victor J Navarro, Jose Serrano, Leonard B Seeff, Huiman X Barnhart, Herbert L Bonkovsky, Timothy Davern, Robert J Fontana, Lafaine Grant, Rajender K Reddy, Averell H SherkerAbstract:Approximately half the US adult population consumes herbals and dietary supplements (HDS),(1,2) with recent reports showing their use to be increasing.(3,4) Supplement users are more commonly women, non-Hispanic whites, over age 40, and have higher levels of education than non-users.(4-7) NHANES III data indicate that multivitamins and minerals are the most common supplements used, followed by calcium and fish oils.(5) However, the range of HDS is far broader and includes numerous commercial products. Although dietary supplements are perceived as safe (8), the current regulatory framework established by the Dietary Supplement Health and Education Act of 1994 (9) requires less evidence of safety prior to marketing as assessed by the Food and Drug Administration (FDA) than is required for pharmaceuticals. The FDA and other regulatory bodies can take action against a manufacturer only if there is proven adulteration or injury from its supplement. Recent cases of life-threatening hepatotoxicity from the dietary supplement OxyElite Pro (10) underscore the potential adverse consequences of this oversight process. The Drug-Induced Liver Injury Network (DILIN), supported by the National Institutes of Diabetes and Digestive and Kidney Diseases, was established in 2003 to identify, enroll, and characterize cases of drug-induced liver injury attributable to medications (excluding acetaminophen) and HDS (ClinicalTrials.gov Identifier:NCT00345930).(11) The original DILIN report identified HDS as the second most common cause for liver injury. (12) Since that report, many more cases have been accrued by the DILIN. Thus, we examined the burden and characteristics of liver injury attributable to HDS in the DILIN, and compared this injury with that due to conventional medications.

drug induced liver injury network dilin prospective study rationale design and conduct
Drug Safety, 2009Co-Authors: Robert J Fontana, Jose Serrano, Herbert L Bonkovsky, Naga Chalasani, Timothy J Davern, Paul B Watkins, James RochonAbstract:Background: Drug-induced liver injury (DILI) is an uncommon adverse drug reaction of increasing importance to the medical community, pharmaceutical industry, regulatory agencies and the general public. Objectives: The Drug-Induced Liver Injury Network (DILIN) was established to advance understanding and research into DILI by initiating a prospective registry of patients with bona fide DILI for future studies of host clinical, genetic, environmental and immunological risk factors. The DILIN was also charged with developing standardized nomenclature, terminology and causality assessment instruments. Methods: Five clinical sites, a data coordinating centre and senior scientists from the National Institute of Diabetes and Digestive and Kidney Diseases initiated the DILIN prospective study in September 2004. Eligible patients are required to meet minimal laboratory or histological criteria within 6 months of DILI onset and have other competing causes of liver injury excluded. Patients in the general community setting with pre-existing HIV, hepatitis B virus or hepatitis C virus infections and/or abnormal baseline liver biochemistries are eligible for enrolment. In addition, subjects with liver injury due to herbal products are eligible to participate. Control patients without DILI are also to be recruited in the future. Results: All referred subjects undergo an extensive review of available laboratory, pathology and imaging studies. Subjects who meet pre-defined eligibility criteria at the 6-month study visit are followed for 2 years to better define the natural history of chronic DILI. Causality assessment is determined by a panel of three hepatologists who independently assign a causality score ranging from 1 (definite) to 5 (unlikely) as well as a severity score ranging from 1 (mild) to 5 (fatal). During the first 3 years, 367 subjects were enrolled into the DILIN prospective study. Conclusion: DILIN is a multicentre research network charged with improving our understanding of the aetiologies, risk factors and outcomes of DILI in the US. The network is meeting the targeted enrolment of ten patients per month and is developing a repository of clinical data and biological samples for future studies of DILI pathogenesis and outcome.

heavy consumption of alcohol is not associated with worse outcomes in patients with idiosyncratic drug induced liver injury compared to non drinkers
Clinical Gastroenterology and Hepatology, 2018Co-Authors: Lara Dakhoul, Victor J Navarro, Naga Chalasani, Marwan Ghabril, Jiezhun Gu, Jose SerranoAbstract:Background & Aims The relationship between alcohol consumption and idiosyncratic drug-induced liver injury (DILI) is not well understood. We investigated the relationship between heavy consumption of alcohol and characteristics and outcomes of patients with DILI enrolled in the Drug-induced Liver Injury Network (DILIN) prospective study. Methods We collected data from 1198 individuals with definite, highly likely, or probable DILI enrolled in the DILIN study from September 2004 through April 2016. At enrollment, all participants were asked about alcohol consumption; those with any alcohol consumption during previous 12 months were asked to complete the Skinner questionnaire to assess drinking history. Heavy consumption of alcohol was defined as more than 3 drinks, on average, per day by men or more than 2 drinks, on average, per day by women. Results Of the 601 persons who reported consuming at least 1 alcoholic drink in the preceding 12 months, 348 completed the Skinner questionnaire and 80 reported heavy consumption of alcohol. Heavy drinkers were younger (average age, 42 years) than non-drinkers (average age, 49 years) and a higher proportion were men (63% of heavy drinkers vs 35% of nondrinkers) ( P P P = .02) and higher levels of bilirubin (16.1 mg/dL vs 12.7 mg/dL in non-drinkers) ( P = .03) but there was no significant difference in liver-related death or liver transplantation between heavy drinkers (occurred in 10%) vs non-drinkers (occurred in 6%) ( P = .18). Conclusion In an analysis of data from the DILIN, we found anabolic steroids to be the most common cause of DILI in individuals who are heavy consumers of alcohol. Compared to non-drinkers, DILI was not associated with a greater proportion of liver-related deaths or liver transplantation in heavy drinkers.

Development of a modified lymphocyte transformation test for diagnosing drug-induced liver injury associated with an adaptive immune response
Taylor & Francis Group, 2017Co-Authors: Jessica Whritenour, Qing Zong, Jianying Wang, Karrie Tartaro, Patricia Schneider, Ellen Olson, Jose Serrano, Maria Van Volkenburg, Paul HayashiAbstract:Drug-induced liver injury (DILI) is a growing problem. Diagnostic methods to differentiate DILI caused by an adaptive immune response from liver injury of other causes or to identify the responsible drug in patients receiving multiple drugs, herbals and/or dietary supplements (polypharmacy) have not yet been established. The lymphocyte transformation test (LTT) has been proposed as a diagnostic method to determine if a subject with an apparent hypersensitivity reaction has become sensitized to a specific drug. In this test, peripheral blood mononuclear cells (PBMC) collected from a subject are incubated with drug(s) suspected of causing the reaction. Cell proliferation, measured by the incorporation of [3H]-thymidine into new DNA, is considered evidence of a drug-specific immune response. The objectives of the current studies were to: (1) develop and optimize a modified version of the LTT (mLTT) and (2) investigate the feasibility of using the mLTT for diagnosing DILI associated with an adaptive immune response and identifying the responsible drug. PBMC collected from donors with a history of drug hypersensitivity reactions to specific drugs (manifested as skin rash) were used as positive controls for assay optimization. Following optimization, samples collected from 24 subjects enrolled in the U.S. Drug-Induced Liver Injury Network (DILIN) were tested in the mLTT. Using cytokine and granzyme B production as the primary endpoints to demonstrate lymphocyte sensitization to a specific drug, most samples from the DILIN subjects failed to respond. However, robust positive mLTT responses were observed for two of four samples from three DILIN subjects with hepatitis due to isoniazid (INH). We conclude that the mLTT, as performed here on frozen and thawed PBMC, is not a reliable test for diagnosing DILI caused by all drugs, but that it may be useful for confirming the role of the adaptive immune response in DILI ascribed to INH

drug induced liver injury summary of a single topic clinical research conference
Hepatology, 2006Co-Authors: Paul B Watkins, Leonard B SeeffAbstract: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.
