Abstract
PURPOSE OF REVIEW Traditional, complementary, and integrative medicine (TCIM) modalities are widely employed. However, TCIM, specifically herbal and non-herbal dietary supplements, can pose challenges in the context of organ transplantation. In this review, we discuss common supplements used for psychiatric purposes and highlight important considerations for candidates and recipients of liver transplants. RECENT FINDINGS Ashwagandha, kava kava, green tea extract, skullcap, turmeric, and valerian have known idiosyncratic hepatotoxic potential and may complicate the liver transplantation course. Multiple supplements reportedly carry a lower risk of hepatotoxicity, though evidence for widespread use in those at risk for or with hepatic impairment is limited. Psychiatrists caring for candidates and recipients of liver transplants must recognize that patients may find supplements helpful in alleviating psychiatric symptoms, despite an overall limited evidence base. Evaluating benefit versus risk ratios and reviewing drug-drug interactions is essential to promote transplant candidacy and mitigate the possibility of native or graft liver dysfunction.

Abstract
Viral hepatitis-induced acute liver failure (ALF) is a preventable cause for liver-related mortality worldwide. Viruses are the most common cause for ALF in developing nations in contrast to the west, where acetaminophen is largely responsible. Viruses may be hepatotropic or affect the liver secondary to a systemic infection. In tropical countries, infections such as leptospirosis, scrub typhus and malaria can mimic the symptoms of ALF. Differentiating these ALF mimics is crucial because they require etiology-specific therapy. Treatment of viral hepatitis-induced ALF is two-pronged and directed towards providing supportive care to prevent organ failures and antiviral drugs for some viruses. Liver transplantation (LT) is an effective modality for patients deteriorating despite adequate supportive care. Early referral and correct identification of patients who require a transplant are important. Liver support devices and plasma exchange have evolved into "bridging modalities" for LT. Preventive strategies such as hand hygiene, use of clean and potable water and inclusion of vaccines against viral hepatitis in the national program are simple yet very effective methods focusing on the preventive aspect of this disease.

Single cell RNA-sequencing analysis reveals that N-acetylcysteine partially reverses hepatic immune dysfunction in biliary atresia. JHEP Rep 2023; 5:100908. [PMID: 37869073 PMCID: PMC10585304 DOI: 10.1016/j.jhepr.2023.100908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 07/12/2023] [Accepted: 08/22/2023] [Indexed: 10/24/2023] Open
Abstract
Background & Aims Our previous study indicated that CD177+ neutrophil activation has a vital role in the pathogenesis of biliary atresia (BA), which is partially ameliorated by N-acetylcysteine (NAC) treatment. Here, we evaluated the clinical efficacy of NAC treatment and profiled liver-resident immune cells via single cell RNA-sequencing (scRNA-seq) analysis to provide a comprehensive immune landscape of NAC-derived immune regulation. Methods A pilot clinical study was conducted to evaluate the potential effects of intravenous NAC treatment on infants with BA, and a 3-month follow-up was carried out to assess treatment efficacy. scRNA-seq analysis of liver CD45+ immune cells in the control (n = 4), BA (n = 6), and BA + NAC (n = 6) groups was performed and the effects on innate cells, including neutrophil and monocyte-macrophage subsets, and lymphoid cells were evaluated. Results Intravenous NAC treatment demonstrated beneficial efficacy for infants with BA by improving bilirubin metabolism and bile acid flow. Two hepatic neutrophil subsets of innate cells were identified by scRNA-seq analysis. NAC treatment suppressed oxidative phosphorylation and reactive oxygen species production in immature neutrophils, which were transcriptionally and functionally similar to CD177+ neutrophils. We also observed the suppression of hepatic monocyte-mediated inflammation, decreased levels of oxidative phosphorylation, and M1 polarisation in Kupffer-like macrophages by NAC. In lymphoid cells, enhancement of humoral immune responses and attenuation of cellular immune responses were observed after NAC treatment. Moreover, cell-cell interaction analysis showed that innate/adaptive proinflammatory responses were downregulated by NAC. Conclusions Our clinical and scRNA-seq data demonstrated that intravenous NAC treatment partially reversed liver immune dysfunction, alleviated the proinflammatory responses in BA by targeting innate cells, and exhibited beneficial clinical efficacy. Impact and implications BA is a serious liver disease that affects newborns and has no effective drug treatment. In this study, scRNA-seq showed that NAC treatment can partially reverse the immune dysfunction of neutrophil extracellular trap-releasing CD177+ neutrophils and Kupffer cells, and lower the inflammatory responses of other innate immune cells in BA. In consequence, intravenous NAC treatment improved the clinical outcomes of patients with BA in term of bilirubin metabolism.

Abstract
BACKGROUND N-acetylcysteine (NAC) is a potentially effective drug for treating ischemia-reperfusion injury in transplanted livers, but its effect remains controversial. METHODS A systematic review and meta-analysis of relevant clinical trials published and registered in the Cochrane Library, MEDLINE, EMBASE, ClinicalTrial.gov , WHO ICTRP, etc, before March 20, 2022 were conducted and registered with PROSPERO (CRD42022315996). Data were pooled using a random effects model or a fixed effects model based on the amount of heterogeneity. RESULTS Thirteen studies with 1121 participants, 550 of whom received NAC, were included. Compared with the control, NAC significantly reduced the incidence of primary graft nonfunction (relative risk [RR], 0.27; 95% confidence interval [CI], 0.08-0.96), the incidence of postoperative complications (RR, 0.52; 95% CI, 0.41-0.67), the peak postoperative aspartate transferase level (mean difference [MD], -267.52; 95% CI, -345.35 to -189.68), and the peak alanine transferase level (MD, -293.29; 95% CI, -370.39 to -216.20). NAC also improved 2-y (RR, 1.18; 95% CI, 1.01-1.38) graft survival rate. However, NAC increased the intraoperative cryoprecipitate (MD, 0.94; 95% CI, 0.42-1.46) and red blood cell (MD, 0.67; 95% CI, 0.15-1.19) requirements. Moreover, NAC was administered in various modes in these studies, including to the donor, recipient, or both. Subgroup analysis and network meta-analysis showed that NAC administration to recipients could play a more significant role than the other 2 administration modes. CONCLUSIONS Our study supports the protective effect of NAC against LT-induced ischemia-reperfusion injury and shows better clinical outcomes of NAC administration to recipients.

[PMID: 35460909 DOI: 10.1016/j.actbio.2022.04.021] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 03/24/2022] [Accepted: 04/11/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Silibinin (SIL) has been extensively studied for its therapeutic effects on various liver diseases. However, its effect on acute liver injury was limited for poor solubility and low bioavailability. Thus, we prepared SIL and bovine serum albumin (SIL/BSA) nanoparticles and further evaluated their therapeutic efficacy against acute liver injury in mouse models. METHODS SIL/BSA nanoparticles were prepared via a nanoprecipitation method. Both in vitro cell culture model and in vivo mouse models of acetaminophen (APAP) and lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced acute liver injury were used to evaluate the therapeutic effect of SIL/BSA nanoparticles and potential mechanisms. RESULTS The SIL/BSA nanoparticles with hydrophilic diameters of 90 ± 29 nm were stably suspended. SIL/BSA nanoparticles presented better biocompatibility and more liver distribution in vivo than SIL microparticles. SIL/BSA nanoparticles significantly alleviated APAP and LPS/D-GalN induced acute liver injury in mice. Similarly, SIL/BSA nanoparticles remarkably enhanced the viability of hepatocytes in vitro against both APAP and LPS/D-GalN induced hepatocyte damage. Moreover, SIL/BSA nanoparticles exhibited antioxidant effects against intracellular oxidative stress via upregulating the nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant responsive element (ARE) pathway, decreasing ROS and regulating antioxidant enzyme reactivity. And the downstream of mitochondria damage and caspase 9/3 related apoptosis pathway was also inhibited CONCLUSION: SIL/BSA nanoparticles were successfully prepared to enhance the liver availability of SIL. Both in vivo and in vitro, SIL/BSA nanoparticles exerted ideal hepatoprotective and antioxidant efficacy against acute liver injury, suggesting the promising future in clinical transfer. STATEMENT OF SIGNIFICANCE In our study, we prepared small-size, stable and well-dispersed silibinin/bovine serum albumin (SIL/BSA) nanoparticles via using simple and cost-effective nanoprecipitation techniques. Their physicochemical and pharmacokinetic characteristics were analyzed. We systematically studied the hepatoprotective and antioxidant efficacy of SIL/BSA both in vivo and in vitro, using two acute liver injury models. These findings revealed that SIL/BSA nanoparticles exerted ideal hepatoprotective and antioxidant efficacy against acute liver injury, suggesting the promising future in clinical transfer.

Abstract
Introduction: Idiosyncratic drug-induced liver injury (DILI) is a rare adverse reaction to drugs and other xenobiotics. DILI has different grades of severity and may lead to acute liver failure (ALF), for which there is no effective therapy. N-acetylcysteine (NAC) has been occasionally tested for the treatment of non-acetaminophen drug-induced ALF. However, limited evidence for its efficacy and safety is currently available. Our aim was to elucidate the benefit and safety of NAC in DILI and evaluate its hepatoprotective effect. Methods: We conducted a systematic review to evaluate the management and prevention focused on NAC in idiosyncratic DILI. The main outcomes included mortality due to DILI, time to normalization of liver biochemistry, transplant-free survival, and adverse events. We included clinical trials and observational studies, either prospective or retrospective. Results: A total of 11 studies were included after literature screening. All studies had different methodologies, and some of them had important risk of bias that may lead to interpreting their findings with caution. The majority of the studies proved NAC efficacy in a cohort of patients with ALF due to different etiologies, where DILI represented a subgroup. NAC seemed to improve transplant-free survival; however, its benefit was inconclusive in terms of overall survival. With regard to safety, NAC showed an adequate safety profile. In prevention studies, NAC showed a possible hepatoprotective effect; however, this finding is limited by the lack of studies and presence of bias. Conclusion: NAC treatment seems to have some benefit in non-acetaminophen drug-induced liver failure patients with acceptable safety; however, due to the lack of evidence and limitations detected across studies, its benefit must be corroborated in clinical trials with adequate methodology.

Abstract
The use of N-acetylcysteine (NAC) for non-acetaminophen-induced acute liver failure (NAI-ALF) has been increasing despite controversy in its efficacy. National guidelines are in disagreement for NAC use as standard of care; however, many healthcare centers continue to adopt the use of NAC outside of acetaminophen poisoning. While NAC may have multiple mechanisms of action in treatment of ALF, this has not translated to clinical benefit. Murine models have reported antioxidant and anti-inflammatory properties, as well as improvement in liver-specific microcirculation. Multiple case studies and series have reported positive outcomes of NAC treatment for ALF of various etiologies. While prospective studies suggested the benefit of NAC treatment, these studies have methodological and statistical shortcomings that affect the validity of the results. In this review, we aimed to summarize the existing literature on the efficacy of NAC for NAI-ALF including mechanism of action, case studies and series demonstrating outcomes, and prospective studies that have led to its current widespread use, along with the reported rate of adverse events.

Abstract
Background Sunitinib and pazopanib are both oral small molecule multityrosine kinase inhibitors (MTKI) used in the treatment of renal cell carcinoma (RCC). Hepatotoxicity or “liver injury” is the most important adverse effect of pazopanib administration, but little is known about the underlying mechanism. Liver injury may also occur in patients treated with sunitinib, but severe toxicity is extremely rare. Herein we report two new cases of severe liver injury induced by MTKI. Both cases are unique and exceptional. We assessed both cases for drug-induced liver injury (DILI) using the updated score Roussel Uclaf causality assessment method (RUCAM). The literature on potential pathogenic mechanisms and precautionary measures is reviewed.
Case presentation A case of a metastatic RCC (mRCC) patient treated with pazopanib who had manifestation of severe liver injury is presented. These manifestations consisted of grade 4 alanine aminotransferase (ALT) increase and grade 4 hyperbilirubinemia. Alternate causes of acute or chronic liver disease were excluded. The patient gradually recovered from the liver injury and refused any further therapy for mRCC. The patient was diagnosed with acute myeloid leukemia (AML) two years later and eventually succumbed to the disease. The second case describes a mRCC patient treated with sunitinib for 3,5 years and fatal liver failure after 2 weeks of clarithromycin co-medication for acute bronchitis. Conclusions Liver injury has been commonly observed in TKI-treated patients with unpredictable course. Management requires regular routine liver enzyme-monitoring and the collaboration of medical oncologist and hepatologist. There is an unmet medical need for a risk stratification and definition of predictive biomarkers to identify potential genetic polymorphisms or other factors associated with TKI-induced liver injury. Any potential unrecommended concomitant therapy has to be avoided.

Abstract
The role of N-acetylcysteine (NAC) in the treatment of acetaminophen induced acute liver injury (ALI) is well established but its role in non-acetaminophen induced ALI is still elusive. We conducted this meta-analysis to evaluate the role of NAC in non-acetaminophen induced ALI. We searched electronic databases for studies published till Oct 25, 2020. We used RevMan v5.4 software to analyze the data extracted from selected studies by using Covidence systematic review software. Outcome estimation was done using Odds Ratio (OR) with 95% confidence interval (CI). The heterogeneity in various studies was determined using the I2 test. A total of 11 studies were included in quantitative analysis. Use of NAC in non-acetaminophen induced ALI showed 53% reduction in mortality compared to standard of care (OR, 0.47; CI, 0.29-0.75) and reduced mean duration of hospital stay by 6.52 days (95% CI, -12.91 to -0.13). Similarly, the rate of encephalopathy was 59% lower in the treatment group (OR, 0.41; CI, 0.20-0.83). However, the risk of developing nausea and vomiting (OR, 3.99; CI, 1.42-11.19), and the need for mechanical ventilation (OR 3.88; CI, 1.14-13.29) were significantly higher in the treatment group. These findings conclude use of NAC decreases mortality and hepatic encephalopathy compared to standard of care in patients with non-acetaminophen induced ALI. Although there is an increased risk of nausea and vomiting with the use of NAC, the majority of adverse events are transient and minor.

Abstract
Many drugs with different mechanisms of action and indications available on the market today are capable of inducing hepatotoxicity. Drug-induced liver injury (DILI) has been a treatment challenge nowadays as it was in the past. We searched Medline (via PubMed), CENTRAL, Science Citation Index Expanded, clinical trials registries and databases of DILI and hepatotoxicity up to 2021 for novel therapies for the management of adult patients with DILI based on the combination of three main search terms: 1) treatment, 2) novel, and 3) drug-induced liver injury. The mechanism of action of novel therapies, the potential of their benefit in clinical settings, and adverse drug reactions related to novel therapies were extracted. Cochrane Risk of bias tool and Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment approach was involved in the assessment of the certainty of the evidence for primary outcomes of included studies. One thousand three hundred seventy-two articles were identified. Twenty-eight articles were included in the final analysis. Eight randomized controlled trials (RCTs) were detected and for six the available data were sufficient for analysis. In abstract form only we found six studies which were also anaylzed. Investigated agents included: bicyclol, calmangafodipir, cytisin amidophospate, fomepizole, livina-polyherbal preparation, magnesium isoglycyrrhizinate (MgIG), picroliv, plasma exchange, radix Paeoniae Rubra, and S-adenosylmethionine. The primary outcomes of included trials mainly included laboratory markers improvement. Based on the moderate-certainty evidence, more patients treated with MgIG experienced alanine aminotransferase (ALT) normalization compared to placebo. Low-certainty evidence suggests that bicyclol treatment leads to a reduction of ALT levels compared to phosphatidylcholine. For the remaining eight interventions, the certainty of the evidence for primary outcomes was assessed as very low and we are very uncertain in any estimate of effect. More effort should be involved to investigate the novel treatment of DILI. Well-designed RCTs with appropriate sample sizes, comparable groups and precise, not only surrogate outcomes are urgently welcome.

Abstract
BACKGROUND N-acetylcysteine infusions have been widely used to reduce ischemia/reperfusion damage to the liver; however, convincing evidence of their benefits is lacking. OBJECTIVE To perform the largest randomized controlled trial to compare the impact of N-acetylcysteine infusion during liver procurement on liver transplant outcomes. METHODS Single center, randomized trial with patients recruited from La Fe University Hospital, Spain, from February 2012 to January 2016. A total of 214 grafts were transplanted and randomized to the N-acetylcysteine group (n = 113) or to the standard protocol without N-acetylcysteine (n = 101). The primary endpoint was allograft dysfunction (Olthoff criteria). Secondary outcomes included metabolomic biomarkers of oxidative stress levels, interactions between cold ischemia time and alanine aminotransferase level and graft and patient survival (ID no. NCT01866644). RESULTS The incidence of primary dysfunction was 34% (31% in the N-acetylcysteine group and 37.4% in the control group [P = 0.38]). N-acetylcysteine administration reduced the alanine aminotransferase level when cold ischemia time was longer than 6 h (P = 0.0125). Oxidative metabolites (glutathione/oxidized glutathione and ophthalmic acid) were similar in both groups (P > 0.05). Graft and patient survival rates at 12 mo and 3 y were similar between groups (P = 0.54 and P = 0.69, respectively). CONCLUSIONS N-acetylcysteine administration during liver procurement does not improve early allograft dysfunction according to the Olthoff classification. However, when cold ischemia time is longer than 6 h, N-acetylcysteine improves postoperative ALT levels.

Efficacy and safety of N-acetylcysteine for the treatment of non-acetaminophen-induced acute liver failure: an updated systematic review and meta-analysis. Clin Exp Hepatol 2021; 7:156-164.

Abstract
Aim of the study N-acetylcysteine (NAC) is the treatment of choice for acetaminophen-induced liver injury. However, recent years have witnessed growing interest in its role in the treatment of acute liver failure (ALF) due to other aetiologies. This study aims to determine both its safety and efficacy by pooling data from multiple studies. Material and methods A search was conducted for all controlled randomized/non-randomized studies that measured the efficacy and safety of NAC in adult patients with non-acetaminophen-induced acute liver failure (NAI-ALF). Transplant-free survival (TFS) was considered the primary endpoint, while secondary endpoints such as length of hospital stay, and incidence of adverse events during treatment, were included in our analysis. Data were pooled via a random-effects model, I2 was used as a measure of heterogeneity, and publication bias was assessed via a funnel plot. Results A total of 3 studies [2 randomized controlled trials (RCTs) and 1 non-randomized cohort] were pooled in this meta-analysis. TFS was significantly higher in patients given NAC, when compared to the placebo/control (PBO) group (RR = 1.54, CI = 1.19-1.98, p = 0.01, I2 = 0.0%). No secondary endpoint was observed to have improved significantly in patients prescribed NAC: length of hospital stay (SMD = –0.405, CI = –1.44-0.63, p = 0.445, I2 = 91.1%), renal failure (RR = 1.01, CI = 0.65-1.57, p = 0.967, I2 = 21.3%), infections (RR = 1.18, CI = 0.91-1.52, p = 0.208, I2 = 2.3%), pulmonary failure (RR = 1.19, CI = 0.57-2.49, p = 0.649, I2 = 84.6%). Minimal side effects were reported in around 10-14% of the patients prescribed NAC. Conclusions NAC was shown to significantly improve TFS in adult patients with NAI-ALF, while no significant benefit was observed concerning the secondary endpoints of length of hospital stay and incidence of adverse effects.

Abstract
OBJECTIVE To review the clinical usefulness of N-acetylcysteine (NAC) as treatment or adjunctive therapy in a number of medical conditions. Use in Tylenol overdose, cystic fibrosis, and chronic obstructive lung disease has been well documented, but there is emerging evidence many other conditions would benefit from this safe, simple, and inexpensive intervention. Quality of Evidence. PubMed, several books, and conference proceedings were searched for articles on NAC and health conditions listed above reviewing supportive evidence. This study uses a traditional integrated review format, and clinically relevant information is assessed using the American Family Physician Evidence-Based Medicine Toolkit. A table summarizing the potential mechanisms of action for N-acetylcysteine in these conditions is presented. Main Message. N-acetylcysteine may be useful as an adjuvant in treating various medical conditions, especially chronic diseases. These conditions include polycystic ovary disease, male infertility, sleep apnea, acquired immune deficiency syndrome, influenza, parkinsonism, multiple sclerosis, peripheral neuropathy, stroke outcomes, diabetic neuropathy, Crohn's disease, ulcerative colitis, schizophrenia, bipolar illness, and obsessive compulsive disorder; it can also be useful as a chelator for heavy metals and nanoparticles. There are also a number of other conditions that may show benefit; however, the evidence is not as robust. CONCLUSION The use of N-acetylcysteine should be considered in a number of conditions as our population ages and levels of glutathione drop. Supplementation may contribute to reducing morbidity and mortality in some chronic conditions as outlined in the article.

Abstract
Supplemental Digital Content is available in the text. OBJECTIVES: Studies of the use of IV N-acetylcysteine in the management of non-acetaminophen-induced acute liver failure have evaluated various dosing regimens. The only randomized trial studying this application described a 72-hour regimen. However, observational studies have reported extended duration until normalization of international normalized ratio. This study seeks to compare differences in patient outcomes based on IV N-acetylcysteine duration. DESIGN: Retrospective cohort study. SETTING: Medical ICU at a large quaternary care academic medical institution and liver transplant center. PATIENTS: Adult patients admitted to the medical ICU who received IV N-acetylcysteine for the treatment of non-acetaminophen-induced acute liver failure. INTERVENTIONS: Patients were divided into cohorts based on duration; standard duration of IV N-acetylcysteine was considered 72 hours, whereas extended duration was defined as continuation beyond 72 hours. MEASUREMENTS AND MAIN RESULTS: The primary outcome was time to normalization of international normalized ratio to less than 1.3 or less than 1.5; secondary outcomes included all-cause mortality and transplant-free survival at 3 weeks. In total, 53 patients were included: 40 in the standard duration cohort and 13 in the extended duration. There were no major differences in baseline characteristics. There was no significant difference in time to international normalized ratio normalization between cohorts. Transplant-free survival was higher with extended duration (76.9% extended vs 41.4% standard; p = 0.03). All-cause mortality at 3 weeks was numerically lower in the extended duration group (0% extended vs 24.1% standard; p = 0.08). CONCLUSIONS: Patients with non-acetaminophen-induced acute liver failure who received extended duration N-acetylcysteine were found to have significantly higher transplant-free survival than patients who received standard duration, although there was no significant difference in time to normalization of international normalized ratio or overall survival. Prospective, randomized, multicenter study is warranted to identify subpopulations of patients with non-acetaminophen-induced acute liver failure who could benefit from extended treatment duration as a bridge to transplant or spontaneous recovery.

Abstract
Acute liver failure is a rare syndrome and is primarily caused by paracetamol toxicity in developed nations. Survival for patients with acute liver failure has steadily improved over the last few decades from approximately 20% to greater than 60%. This marked improvement in survival has been due to a combination of improvements in medical practice and the use of emergency liver transplantation in selected patients. Early recognition and timely initial management in the non-specialist centre can significantly improve outcomes. Patients should be simultaneously discussed with a transplant centre and referred to critical care. Close liaison with transplant centres to ensure timely transfer in deteriorating patients is important.

Abstract
Background The American Association for the Study of Liver Diseases recommends that N-acetylcysteine (NAC) may be beneficial in non-acetaminophen-related drug-induced liver injury. A subsequent review and analysis reported the current evidence to be inconclusive. Herein, we present an updated review and meta-analysis. Methods We evaluated prospective, retrospective and randomized controlled trials that compared outcomes in patients of all ages with acute liver failure (defined as abnormal liver enzymes along with elevated international normalized ratio >1.5, with or without hepatic encephalopathy) receiving NAC with the outcomes in a control group. The primary outcome was to compare the overall survival in the 2 groups. Secondary outcomes included difference in length of hospital stay, transplant-free survival, and post-transplant survival. Results Seven studies (N=883) that met the inclusion criteria were included in this analysis. The mean age of patients in the NAC group was 21.22 years compared with 23.62 years in the control group. The odds of overall survival were significantly higher in the NAC group than in controls (odds ratio [OR] 1.77, 95% confidence interval [CI] 1.3-2.41). Post-transplant survival (OR 2.44, 95%CI 1.11-5.37) and transplant-free survival were also better in the NAC group than in the control group (OR 2.85, 95%CI 2.11-3.85). Patients in the control group had statistically significant odds of a longer inpatient stay (mean difference 7.79, 95%CI 6.93-8.66). Conclusion In patients with non-acetaminophen-related acute liver failure, NAC significantly improves overall survival, post-transplant survival and transplant-free survival while decreasing the overall length of hospital stay.

Abstract
BACKGROUND Acute liver failure is a rare and serious disease. Acute liver failure may be paracetamol-induced or non-paracetamol-induced. Acute liver failure not caused by paracetamol (acetaminophen) has a poor prognosis with limited treatment options. N-acetylcysteine has been successful in treating paracetamol-induced acute liver failure and reduces the risk of needing to undergo liver transplantation. Recent randomised clinical trials have explored whether the benefit can be extrapolated to treat non-paracetamol-related acute liver failure. The American Association for the Study of Liver Diseases (AASLD) 2011 guideline suggested that N-acetylcysteine could improve spontaneous survival when given during early encephalopathy stages for patients with non-paracetamol-related acute liver failure. OBJECTIVES To assess the benefits and harms of N-acetylcysteine compared with placebo or no N-acetylcysteine, as an adjunct to usual care, in people with non-paracetamol-related acute liver failure. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register (searched 25 June 2020), Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 6) in The Cochrane Library, MEDLINE Ovid (1946 to 25 June 2020), Embase Ovid (1974 to 25 June 2020), Latin American and Caribbean Health Science Information database (LILACS) (1982 to 25 June 2020), Science Citation Index Expanded (1900 to 25 June 2020), and Conference Proceedings Citation Index - Science (1990 to 25 June 2020). SELECTION CRITERIA We included randomised clinical trials that compared N-acetylcysteine at any dose or route with placebo or no intervention in participants with non-paracetamol-induced acute liver failure. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as described in the Cochrane Handbook for Systematic Reviews of Interventions. We conducted meta-analyses and presented results using risk ratios (RR) with 95% confidence intervals (CIs). We quantified statistical heterogeneity by calculating I2. We assessed bias using the Cochrane risk of bias tool and determined the certainty of the evidence using the GRADE approach. MAIN RESULTS We included two randomised clinical trials: one with 183 adults and one with 174 children (birth through age 17 years). We classified both trials at overall high risk of bias. One unregistered study in adults is awaiting classification while we are awaiting responses from study authors for details on trial methodology (e.g. randomisation processes). We did not meta-analyse all-cause mortality because of significant clinical heterogeneity in the two trials. For all-cause mortality at 21 days between adults receiving N-acetylcysteine versus placebo, there was inconclusive evidence of effect (N-acetylcysteine 24/81 (29.6%) versus placebo 31/92 (33.7%); RR 0.88, 95% CI 0.57 to 1.37; low certainty evidence). The certainty of the evidence was low due to risk of bias and imprecision. Similarly, for all-cause mortality at one year between children receiving N-acetylcysteine versus placebo, there was inconclusive evidence of effect (25/92 (27.2%) versus 17/92 (18.5%); RR 1.47, 95% CI 0.85 to 2.53; low certainty evidence). We downgraded the certainty of evidence due to very serious imprecision. We did not meta-analyse serious adverse events and liver transplantation at one year due to incomplete reporting and clinical heterogeneity. For liver transplantation at 21 days in the trial with adults, there was inconclusive evidence of effect (RR 0.72, 95% CI 0.49 to 1.06; low certainty evidence). We downgraded the certainty of the evidence due to serious risk of bias and imprecision. For liver transplantation at one year in the trial with children, there was inconclusive evidence of effect (RR 1.23, 95% CI 0.84 to 1.81; low certainty of evidence). We downgraded the certainty of the evidence due to very serious imprecision. There was inconclusive evidence of effect on serious adverse events in the trial with children (RR 1.25, 95% CI 0.35 to 4.51; low certainty evidence). We downgraded the certainty of the evidence due to very serious imprecision. We did not meta-analyse non-serious adverse events due to clinical heterogeneity. There was inconclusive evidence of effect on non-serious adverse events in adults (RR 1.07, 95% CI 0.79 to 1.45; 173 participants; low certainty of evidence) and children (RR 1.19, 95% CI 0.62 to 2.16; 184 participants; low certainty of evidence). None of the trials reported outcomes of proportion of participants with resolution of encephalopathy and coagulopathy or health-related quality of life. The National Institute of Health in the United States funded both trials through grants. One of the trials received additional funding from two hospital foundations' grants. Pharmaceutical companies provided the study drug and matching placebo, but they did not have input into study design nor involvement in analysis. AUTHORS' CONCLUSIONS The available evidence is inconclusive regarding the effect of N-acetylcysteine compared with placebo or no N-acetylcysteine, as an adjunct to usual care, on mortality or transplant rate in non-paracetamol-induced acute liver failure. Current evidence does not support the guideline suggestion to use N-acetylcysteine in adults with non-paracetamol-related acute liver failure, nor the rising use observed in clinical practice. The uncertainty based on current scanty evidence warrants additional randomised clinical trials with non-paracetamol-related acute liver failure evaluating N-acetylcysteine versus placebo, as well as investigations to identify predictors of response and the optimal N-acetylcysteine dose and duration.

Abstract
Autoimmune hepatitis is associated with varied clinical presentations and natural history, as well as somewhat unpredictable treatment responses. Understanding how to stratify patients who require further escalation of therapy will help clinicians manage these patients. The presentation of acute severe autoimmune hepatitis (AS-AIH) is relatively uncommon, although its prevalence is potentially greater than currently perceived. Previous studies consist of small retrospective single-centre series and are not directly comparable due to the diversity of presentations, disease definitions and non-standardised treatment regimens. We define AS-AIH as those who present acutely with AIH and are icteric with an international normalised ratio ≥1.5 and no evidence of hepatic encephalopathy. Those with hepatic encephalopathy should be defined as having AS-AIH with acute liver failure. In this review, we provide a structured practical approach for diagnosing and managing this unique group of patients.

Androgenic anabolic steroid-induced liver injury: two case reports assessed for causality by the updated Roussel Uclaf Causality Assessment Method (RUCAM) score and a comprehensive review of the literature. BMJ Open Gastroenterol 2020; 7:bmjgast-2020-000549. [PMID: 33214235 PMCID: PMC7678230 DOI: 10.1136/bmjgast-2020-000549] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Accepted: 10/03/2020] [Indexed: 12/11/2022] Open
Abstract
Background Anabolic androgenic steroids (AAS) usage is widespread and increasing. AAS drug-induced liver injury (DILI) is recognised but its clinical course and management is poorly described. We report 2 cases of AAS DILI with associated renal dysfunction, managed successfully with oral corticosteroids. Methods A comprehensive review identified 50 further cases to characterise the clinical and biochemical course. Causality grading was calculated using the updated Roussel Uclaf Causality Assessment Method (RUCAM) score. Data are presented as median values. Results The most common AAS taken was methyldrostanolone. Patients commonly present with jaundice and pruritus but may exhibit other constitutional symptoms. Patients presented 56 days after starting, and bilirubin peaked 28 days after stopping, AAS. Causality assessment was ‘unlikely’ in 1 (2%), ‘possible’ in 31 (60%) and ‘probable’ in 20 (38%). Peak values were: bilirubin 705 μmol/L, alanine transaminase 125 U/L, aspartate transaminase 71 U/L, alkaline phosphatase 262 U/L, gamma-glutamyl transferase 52 U/L, international normalised ratio 1.1. Liver biopsies showed ‘bland’ canalicular cholestasis. 43% of patients developed kidney injury (peak creatinine 225 μmol/L). Therapies included antipruritics, ursodeoxycholic acid and corticosteroids. No patients died or required liver transplantation. Conclusions Physicians are likely to encounter AAS DILI. Causality assessment using the updated RUCAM should be performed but defining indications and proving efficacy for therapies remains challenging.

[PMID: 33161366 DOI: 10.1016/j.critrevonc.2020.103127] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 09/29/2020] [Accepted: 10/05/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Multikinase inhibitors (MKI) are targeted molecular agents that have revolutionized cancer management. However, there is a paucity of data concerning MKI-related liver injury risk and clinical guidelines for the management of liver toxicity in patients receiving MKI for cancer are scarce. DESIGN We conducted a PubMed search of articles in English published from January 2000 to December 2018 related to hepatotoxicity of the 29 FDA-approved MKIs at doses used in clinical practice. The search terms were the international non-proprietary name of each agent cross-referenced with «hepatotoxicity», «hepatitis», «hepatic adverse event», or «liver failure», and «phase II clinical trial», «phase III clinical trial», or «case report». RESULTS Following this search, 140 relevant studies and 99 case reports were considered. Although asymptomatic elevation of aminotransferase levels has been frequently observed in MKI clinical trials, clinically significant hepatotoxicity is a rare event. In most cases, the interval between treatment initiation and the onset of liver injury is between one week and two months. Liver toxicity is often hepatocellular and less frequently mixed. Life-threatening MKI-induced hepatic injury has been described, involving fulminant liver failure or death. Starting from existing data, a description of MKI-related liver events, grading of hepatotoxicity risk, and recommendations for management are also given for various MKI molecules. CONCLUSION All MKIs can potentially cause liver injury, which is sometimes irreversible. As there is still no strategy available to prevent MKI-related hepatotoxicity, early detection remains crucial. The surveillance of liver function during treatment may help in the early detection of hepatotoxicity. Furthermore, the exclusion of potential causes of hepatic injury is essential to avoid unnecessary MKI withdrawal.

Abstract
Zinc phosphide (Zn3P2) is a phosphine-generating pesticide. Serious hepatotoxicity or cardiotoxicity might develop late in initially stable patients. The current prospective study aimed to predict Zn3P2-induced hepatotoxicity and cardiotoxicity. This prospective cross-sectional study included 150 patients admitted to the Alexandria Poison Center (APC) for over 6 months (from August 2018 to January 2019). The recorded patients' data included personal data, poisoning, medical history, clinical assessment using the poisoning severity score (PSS), investigations, and the outcome. The mean age of the patients was 23.36 ± 13.53 years. Females constituted 68.7%, and 76% of the patients ingested Zn3P2 deliberately. Only two cases that ingested the highest amount of Zn3P2 had radio-opaque shadows in the abdominal plain X-ray. The peak of clinical manifestations was in 12 h, whereas the peak liver transaminases (alanine aminotransferase (ALT), aspartate aminotransferase (AST)) and cardiac enzymes (creatine phosphokinase (CPK), creatine kinase-muscle/brain (CK-MB), troponin) were in 24 h. No fatalities were reported, 56.7% are completely cured, 37.3% are discharged on consent, and 6% are discharged with elevated liver and/or cardiac enzymes. The receiver operating characteristic (ROC) curve was applied. Persistent elevation of liver enzymes after 72 h could be predicted if the ingested amount > 3.5 (accuracy 86.2%), time till hospitalization > 5 h (accuracy 85.9%), PSS > 1 with (accuracy 58.9%), AST > 50 U/L (accuracy 86.2%), or ALT > 82 U/L (accuracy 86.3%). Elevation of cardiac enzymes could be predicted if the ingested amount > 2.5 sachets (accuracy 99.5%), time till hospitalization > 5 h (accuracy 99.7%), PSS > 1 with (accuracy 61.2%), CPK > 260 U/L (accuracy 99.9%), CK-MB > 6 ng/mL (accuracy 99.7%), or troponin > 0.9 ng/mL (accuracy 99.8%).

Abstract
Drug-induced liver injury (DILI) is the most common cause of acute liver failure (ALF) in Western countries. Without liver transplantation, the mortality rate for ALF approaches greater than 80%. Acetaminophen-related ALF may be associated with a rapid progression but fortunately has a high chance for spontaneous survival compared with idiosyncratic DILI-related ALF. Several prognostic scoring systems for severe DILI have been developed to aid clinicians in selecting patients who require urgent liver transplantation. Patients who undergo liver transplantation for ALF are at risk for early graft loss and death and should be closely followed.

Abstract
Importance Rodenticide poisoning is a common occurrence in India. Of the different classes of rodenticides available, yellow phosphorus is considered highly toxic. There are scarce epidemiological data regarding the ingestion of yellow phosphorus in the subcontinent. Objectives This study aimed to identify the clinical profile of rodenticide-poisoned patients and delineate mortality predictors. Design Prospective observational study. Setting and participants Study was conducted at the Department of Internal Medicine, Government Villupuram Medical College and Hospital. All adult inpatients with a history of rodenticide poison exposure were eligible participants. A total of 99 patients completed the study protocol. Main outcome Survival with or without morbidity and death. Results In all, 90.91% of patients consumed the paste formulation of rodenticide [yellow phosphorus (67.2%) and yellow phosphorus + zinc phosphide (24%)].The time to resuscitation showed significance to mortality. Survival rate among patients instituted gastric decontamination within 2 hours of exposure (97.87%) was significantly higher than those who were not (84.62%) (p = 0.033). The clinical picture revealed conspicuous absence of signs and symptoms during the first 24 hours. In all, 72.73% (n = 72) manifested with toxidrome after a lag period of 24–36 hours (range 18–72 hours). The dominant clinical manifestations included abdominal pain (52.53%), jaundice (22.21%), coagulopathy (15.15%), encephalopathy (10.10%), shock (10.10%), acute kidney injury (AKI; 7.08%), and multi-organ failure (17.17%). Laboratory data showed elevated aspartate transaminase (AST; 48.47%), alanine aminotransferase (ALT; 49.50%), bilirubin levels (22.21%), metabolic acidosis (10.12%), serum creatinine (7.08%), prothrombin time prolongation (PT/INR; 15.15%), and activated partial thromboplastin time (aPTT) (3.30%). The mortality was 9.1% (n = 9) of which 77.78% (n = 7) died of fulminant hepatic failure. The mean time for death was 4.22 days since exposure (range 2–8 days). Conclusion Rodenticide poisoning in Southern India is dominated by yellow phosphorus. In this study, we identified delayed resuscitation, jaundice, hepatic encephalopathy, elevation of AST and ALT to >1000 IU/L, metabolic acidosis, and refractory shock as reliable predictors of bad outcome in this patient population. The common mode of death was fulminant hepatic failure. Relevance Rodenticide poisoning ranks second in mortality hierarchy at our institute, and systematic analysis of this patient population is an urgent need.

Abstract
BACKGROUND Nowadays, pharmacological treatment of non-alcoholic fatty liver disease (NAFLD) is still limited and it is based on the treatment of conditions associated comorbities. Oxidative stress and insulin resistance are the mechanisms that seem to be mostly involved in its pathogenesis. OBJECTIVE To evaluate the efficacy of N-acetylcysteine (NAC) in combination with metformin (MTF) and/or ursodeoxycholic acid (UDCA) for treatment of non-alcoholic steatohepatitis (NASH). METHODS Open-label multicenter randomized trial was conducted for 48 weeks. It included patients with biopsy-proven NASH. The patients were randomized into three groups: NAC (1.2 g) + UDCA (15 mg/kg) + MTF (850-1500 mg/day) (n=26); UDCA (20 mg/kg) + MTF (850-1500 mg/day) (n=13); NAC (1.2g) + MTF (850-1500 mg/day) (n=14) for 48 weeks. Clinical, laboratory and the second liver biopsies were performed after 48 weeks. RESULTS A total of 53 patients were evaluated; 17 (32.1%) were males; median age ±54 (IQR=15, 21-71) years. In the baseline, no difference was seen between groups according clinical and histological parameters. The groups differed only in cholesterol, LDL and triglycerides. No significant differences in biochemical and histologic parameters were found between these the three groups after 48 weeks of treatment. In the intragroup analysis (intention-to-treat) comparing histological and biochemical features, there were significant improvements in the steatosis degree (P=0.014), ballooning (0.027) and, consequently, in the NAFLD Activity Score (NAS) (P=0.005), and in the ALT levels at the end of the treatment only in the NAC + MTF group. No significant evidence of modification in the liver fibrosis could be observed in any of the groups. CONCLUSION This multicenter study suggests that the association of NAC + MTF could reduce the liver disease activity in patients with NASH. These data stimulate further controlled studies with this therapy for these patients.

Abstract
Idiosyncratic (unpredictable) drug-induced liver injury is one of the most challenging liver disorders faced by hepatologists, because of the myriad of drugs used in clinical practice, available herbs and dietary supplements with hepatotoxic potential, the ability of the condition to present with a variety of clinical and pathological phenotypes and the current absence of specific biomarkers. This makes the diagnosis of drug-induced liver injury an uncertain process, requiring a high degree of awareness of the condition and the careful exclusion of alternative aetiologies of liver disease. Idiosyncratic hepatotoxicity can be severe, leading to a particularly serious variety of acute liver failure for which no effective therapy has yet been developed. These Clinical Practice Guidelines summarize the available evidence on risk factors, diagnosis, management and risk minimization strategies for drug-induced liver jury.

Abstract
Drug-induced liver injury (DILI) is an uncommon but important cause of liver disease that can arise after exposure to a multitude of drugs and herbal and dietary supplements. The severity of idiosyncratic DILI varies from mild serum aminotransferase elevations to the development of severe liver injury that can progress to acute liver failure resulting in death or liver transplantation within days of DILI onset. Chronic liver injury that persists for more than 6 months after DILI onset is also becoming increasingly recognized in up to 20% of DILI patients. Host demographic (age, gender, race), clinical and laboratory features at DILI onset have been associated with the severity and outcome of liver injury in DILI patients. In addition to cessation of the suspect drug, other medical interventions including the use of N-acetylcysteine and corticosteroids in selected patients have shown some clinical benefit, but additional prospective studies are needed. A number of promising diagnostic, prognostic and mechanistic serum and genetic biomarkers may help improve our understanding of the pathogenesis and treatment of idiosyncratic DILI.

Abstract
BACKGROUND & AIMS The analgesic flupirtine has been linked to cases of severe idiosyncratic drug-induced liver injury (sFILI). We therefore examined whether N-acetylcysteine (NAC) and glucocorticoid therapy is effective in the management of sFILI. METHODS In a retrospective cohort study efficacy of NAC-infusion and oral prednisolone treatments on liver-function-tests (LFTs) and clinical outcome of 21 sFILI cases was evaluated by comparing it to an external cohort of 30 sFILI cases not receiving the antidote. LFTs were also assayed in human hepatocyte cultures treated with flupirtine for 96 hours. Additionally, modulation of glutathione stores in cultures of human hepatocytes treated with 80 drugs was investigated. RESULTS Upon admission, patients presented Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and bilirubin elevations of up to 90-, 35- and 30-fold of upper limits of normal (ULN) respectively. The average INR was 2.2, and 50% of patients had a high Model for end-stage liver disease (MELD) score of ≥25 and included 5 cases of 28-32. The combined NAC/prednisolone treatment was well tolerated and led to significant ALT, AST and INR improvements within 2 weeks. However, the hyperbilirubinaemia resolved slowly. Two patients with late start of NAC/prednisolone treatment developed hepatic encephalopathy and required liver transplantation; the remaining patients recovered without long-term sequela. Based on serum biochemistries sFILI cases resolved more rapidly (P < .01) when compared to untreated sFILI patients and included a case with fatal outcome. Additionally, in vitro studies revealed glutathione depletion as a common culprit for drugs with liver liabilities. CONCLUSIONS Based on these initial findings a prospective randomized clinical trial (RCT) is needed to confirm safety and efficacy of NAC/prednisolone treatment in sFILI.

Abstract
Acute liver failure (ALF) requires urgent attention to identify etiology and determine prognosis, in order to assess likelihood of survival or need for transplantation. Identifying idiosyncratic drug-induced liver injury (iDILI) may be particularly difficult, but the illness generally follows a subacute course, allowing time to assess outcome and find a liver graft if needed. Not all drugs that cause iDILI lead to ALF; the most common are antibiotics including anti-tuberculous medications, non-steroidal anti-inflammatory agents and herbal and dietary supplements (HDS). Determining causality remains challenging particularly if altered mentation is present; identifying the causative agent depends in part on knowing the propensity of the drugs that have been taken in the proper time interval, plus excluding other causes. In general, iDILI that reaches the threshold of ALF will more often than not require transplantation, since survival without transplant is around 25%. Treatment consists of withdrawal of the presumed offending medication, consideration of N-acetylcysteine (NAC), as well as intensive care. Corticosteroids have not proven useful except perhaps in instances of apparent autoimmune hepatitis caused by a limited number of agents. Recently developed prognostic scoring systems may also aid in predicting outcome in this setting.

Abstract
Background Pediatric acute-liver-failure due to acetaminophen (APAP) administration at therapeutic dosage is rare, while viral infections and metabolic defects are the prevalent causes. Yet, as acetaminophen is routinely used in febrile illnesses, it may be mistakenly held responsible for the acute liver damage. Case presentation An 11 month old boy had been on acetaminophen for 10 days (total dose 720 mg = 72 mg/kg) when he developed acute-liver-failure with encephalopathy. As he rapidly improved on N-acetylcysteine (NAC) infusion, it was concluded that chronic acetaminophen administration in an infant had lead to acute-liver-failure even at therapeutic doses, that N-acetylcysteine infusion had been life-saving and should be immediately started in similar circumstances. The child, however, had two further episodes of acute liver damage over a 34-month period, without having been given acetaminophen, as the parents carefully avoided using it. His clinical, laboratory and radiological findings between the acute episodes were unremarkable. His features and skeletal surveys were not suggestive of a syndromic condition. He then went on to suffer another episode of acute-liver-failure with multi-organ failure, necessitating an urgent liver transplant. All efforts to come to a diagnosis for the causes of his recurrent episodes of liver failure had been unsuccessful, until a biallelic mutation in the NBAS gene was reported to be associated with recurrent acute-liver-failure in children. The boy’s DNA analysis revealed compound heterozygous pathogenic mutations in the NBAS gene. Liver failure episodes in these patients are triggered and worsened by fever, most likely due to thermal susceptibility of hepatocytes, hence APAP, rather than being a culprit, is part of the supportive treatment. Conclusions We suggest that, in acute-liver-failure with a history of acetaminophen exposure at therapeutic dosage, clinicians should not be contented with administering NAC, but should consider an alternative etiology, above all if the episodes are recurrent, and actively start supportive and antipyretic treatment while seeking the advice of a specialist unit.

Abstract
The Tamarix gallica leaves extract (TGLE) was investigated for hepatoprotective potential against rifampicin (RIF) plus isoniazid (INH)-induced liver injury in Sprague Dawley (SD) rats. All the rats of groups III and IV received 100 and 200 mg/kg body wt, respectively, of the suspension of TGLE while group V received silymarin 100 mg/kg body wt orally. After 10 min, they, along with group II, received INH plus RIF each day (50 mg/kg body wt, by mouth (PO) each) for 28 days. Group I received 10 ml/kg body wt, PO of vehicle, i.e., 1% aqueous carboxymethyl cellulose (1% CMC) throughout the study. At the end of the experiment, blood was obtained through the retro-orbital plexus under light anesthesia and the serum was separated from the sacrificed animals. A small portion of isolated liver tissue was fixed in 10% formaldehyde for histopathological examinations. The levels of elevated serum bilirubin (p > .05-p < .05), alanine transaminase (p > .05-p < .01), aspartate transaminase (p > .05-p < .01), alkaline phosphatase (p < .05-p < .01), lactate dehydrogenase (p < .05-p < .01), and cholesterol (p > .05-p < .01) decreased while the levels of decreased total protein (p > .05-p < .05) and albumin (p < .05-p < .05) increased in TGLE-treated groups III and IV as compared to group II, and the serum marker enzyme levels were toward normal, indicating protection against liver injury. It was well supported with histopathological results. Thus, Tamarix gallica leaves extract possesses promising hepatoprotective activity against RIF plus INH-induced liver injury in experimental rats.

Abstract
The term acute liver failure (ALF) is frequently applied as a generic expression to describe patients presenting with or developing an acute episode of liver dysfunction. In the context of hepatological practice, however, ALF refers to a highly specific and rare syndrome, characterised by an acute abnormality of liver blood tests in an individual without underlying chronic liver disease. The disease process is associated with development of a coagulopathy of liver aetiology, and clinically apparent altered level of consciousness due to hepatic encephalopathy. Several important measures are immediately necessary when the patient presents for medical attention. These, as well as additional clinical procedures will be the subject of these clinical practice guidelines.

Abstract
BACKGROUND/AIMS Acute liver failure (ALF) is a rare but severe medical emergency. To date, there is no established treatment for non-acetaminophen-induced acute liver failure (NAI-ALF) other than liver transplantation, and little is known about the use of N-acetylcysteine (NAC) in NAI-ALF. A randomized case control study was conducted with the aim to determine the effect of NAC on the mortality of NAI-ALF patients, as well as to evaluate the safety and efficacy of NAC use. PATIENTS AND METHODS A total of 80 patients diagnosed with NAI-ALF were included in the study. Forty patients received NAC infusion for 72 h whereas the control group received placebo. The variables evaluated were demographic characteristics, signs and symptoms, biochemical parameters, and clinical course during hospitalization. RESULTS The two groups (NAC and control) were comparable for various baseline characteristics (such as etiology of ALF, INR, alanine aminotransferase, creatinine, albumin, and grade of encephalopathy), except for age. Although majority of patients had undetermined etiology (32.5% in NAC group and 42.5% in control group), the second main cause was acute hepatitis E and drug or toxin-induced ALF. The mortality decreased to 28% with the use of NAC versus 53% in the control group (P = 0.023). The use of NAC was associated with shorter length of hospital stay in survived patients (P = 0.002). Moreover, the survival of patients was improved by NAC (P = 0.025). Also, drug-induced ALF showed improved outcome compared to other etiologies. CONCLUSION The findings of the study recommend the use of NAC along with conventional treatments in patients with NAI-ALF in non-transplant centers while awaiting referrals and conclude the use of NAC as safe.

Abstract
BACKGROUND The ischemia/reperfusion (I/R) phenomenon can cause the dysfunction of some transplanted organs and other distant organs. Liver surgery success, including transplantations, may depend on the adverse effects of intestinal mucosa injury arising from temporary porta triad occlusion. The study objective was to examine I/R liver effects on the small intestine in rats after N-acetylcysteine (NAC) treatment. METHODS Twenty-four male Wistar rats were randomly divided into 2 groups. After anesthesia, they underwent 30 minutes of hepatic ischemia by clamping the porta triad, followed by reperfusion for 30 minutes or 6 hours. Each group was divided into 2 subgroups (n = 6), with 1 group receiving 0.9% saline solution (control) and the other receiving 150 mg/kg of NAC, 15 minutes before hepatic ischemia. At the end of reperfusion, blood was collected for enzyme dosage (alanine aminotransferase [ALT], aspartate aminotransferase [AST], lactate dehydrogenase [LDH], alkaline phosphatase [ALP]), and the terminal ileum was resected to study mucosal morphology by optical microscopy, computerized histomorphometry, and immunohistochemical assessment of apoptosis with caspase 3. RESULTS After 30 minutes of reperfusion, animals receiving NAC had lower injury in the intestinal mucosa compared to the control subgroup (P < .05). After 6 hours, AST was higher in the control subgroup than in the NAC subgroup (P < .05), and AST, ALT and LDH values showed a significant increase in both subgroups (P < .05). CONCLUSION These findings show the deleterious effects of late (6-hour) reperfusion and the protective effect of NAC at 30 minutes, when evaluating the small intestine impact of I/R liver damage.

Abstract
The syndrome of haemolysis, elevated liver enzymes and low platelets is a rare condition specific to pregnancy, affecting approximately 5-20% of all pre-eclamptic pregnancies. Described here is a woman in her first pregnancy, who experienced an intrauterine death following a significant hepatic haematoma and capsular rupture, in the absence of classical clinical features suggestive of pre-eclampsia. The events that followed suggested haemolysis, elevated liver enzymes and low platelets syndrome as the likely diagnosis. The patient's clinical course highlights the difficulties that may be encountered when making decisions about pregnant women with complicated medical and obstetric issues.

Abstract
Hepatitis B virus (HBV) and tuberculosis bacillus (TB) are leading causes of infectious diseases in China, leading to a range of life-threaten diseases including chronic hepatitis B (CHB), cirrhosis, hepatocellular carcinoma (HCC) and pulmonary tuberculosis (PTB). Due to the high prevalence of infection and increased number of cases, coinfection of HCC and PTB is becoming a new hot area. Differences between coinfection and single infection include the disease process, injuries, medication selection, curative effects, drug-resistance and side effects. In particular, the adverse effects of clinical prognosis, etiological treatment, anti-tuberculosis drug induced liver injury (ATLI) and multidrug-resistant pulmonary tuberculosis (MDR-TB) have became a new challenge for therapy. This review aims to summarize the incidence of infections, clinical observations, adversely effects and existing problems of treatment, the development of antituberculous and anti-HBV therapy and hepatitis protection. Additionally, a suggestion for improving therapeutic efficacy has been proposed as well.

Abstract
The etiology and outcomes of acute liver failure (ALF) have changed since the definition of this disease entity in the 1970s. In particular, the role of emergency liver transplantation has evolved over time, with the development of prognostic scoring systems to facilitate listing of appropriate patients, and a better understanding of transplant benefit in patients with ALF. This review examines the changing etiology of ALF, transplant benefit, outcomes following transplantation, and future alternatives to emergency liver transplantation in this devastating condition.

Abstract
While the pace of discovery of new agents, mechanisms and risk factors involved in drug-induced liver injury (DILI) remains brisk, advances in the treatment of acute DILI seems slow by comparison. In general, the key to treating suspected DILI is to stop using the drug prior to developing irreversible liver failure. However, predicting when to stop is an inexact science, and commonly used ALT monitoring is an ineffective strategy outside of clinical trials. The only specific antidote for acute DILI remains N-acetylcysteine (NAC) for acetaminophen poisoning, although NAC is proving to be beneficial in some cases of non-acetaminophen DILI in adults. Corticosteroids can be effective for DILI associated with autoimmune or systemic hypersensitivity features. Ursodeoxycholic acid, silymarin and glycyrrhizin have been used to treat DILI for decades, but success remains anecdotal. Bile acid washout regimens using cholestyramine appear to be more evidenced based, in particular for leflunomide toxicity. For drug-induced acute liver failure, the use of liver support systems is still investigational in the United States and emergency liver transplant remains limited by its availability. Primary prevention appears to be the key to avoiding DILI and the need for acute treatment. Pharmacogenomics, including human leukocyte antigen genotyping and the discovery of specific DILI biomarkers offers significant promise for the future. This article describes and summarizes the numerous and diverse treatment and prevention modalities that are currently available to manage DILI.

Abstract
Drug-induced liver injury (DILI) and herb-induced liver injury is a hot topic for clinicians, academia, drug companies and regulators, as shown by the steadily increasing number of publications in the past 15 years. This review will first provide clues for clinicians to suspect idiosyncratic (unpredictable) DILI and succeed in diagnosis. Causality assessment remains challenging and requires careful medical history as well as awareness of multifaceted aspects, especially for herbs. Drug discontinuation and therapy reconciliation remain the mainstay in patent’s management to minimize occurrence of acute liver failure. The second section will address novel agents associated with liver injury in 2014 (referred to as “signals”), especially in terms of clinical, research and drug development implications. Insights will be provided into recent trends by highlighting the contribution of different post-marketing data, especially registries and spontaneous reporting systems. This literature scrutiny suggests: (1) the importance of post-marketing databases as tools of clinical evidence to detect signals of DILI risk; and (2) the need for joining efforts in improving predictivity of pre-clinical assays, continuing post-marketing surveillance and design ad hoc post-authorization safety studies. In this context, ongoing European/United States research consortia and novel pharmaco-epidemiological tools (e.g., specialist prescription event monitoring) will support innovation in this field. Direct oral anticoagulants and herbal/dietary supplements appear as key research priorities.
