Abstract
Neuroinflammation accompanies several brain disorders, either as a secondary consequence or as a primary cause and may contribute importantly to disease pathogenesis. Neurosteroids which act as Positive Steroid Allosteric GABA-A receptor Modulators (Steroid-PAM) appear to modulate neuroinflammation and their levels in the brain may vary because of increased or decreased local production or import from the systemic circulation. The increased synthesis of steroid-PAMs is possibly due to increased expression of the mitochondrial cholesterol transporting protein (TSPO) in neuroinflammatory tissue, and reduced production may be due to changes in the enzymatic activity. Microglia and astrocytes play an important role in neuroinflammation, and their production of inflammatory mediators can be both activated and inhibited by steroid-PAMs and GABA. What is surprising is the finding that both allopregnanolone, a steroid-PAM, and golexanolone, a novel GABA-A receptor modulating steroid antagonist (GAMSA), can inhibit microglia and astrocyte activation and normalize their function. This review focuses on the role of steroid-PAMs in neuroinflammation and their importance in new therapeutic approaches to CNS and liver disease.

[PMID: 38674921 PMCID: PMC11055039 DOI: 10.3390/nu16081232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/13/2024] [Accepted: 04/19/2024] [Indexed: 04/28/2024] Open
Abstract
OBJECTIVE L-carnitine (LC), a vital nutritional supplement, plays a crucial role in myocardial health and exhibits significant cardioprotective effects. LC, being the principal constituent of clinical-grade supplements, finds extensive application in the recovery and treatment of diverse cardiovascular and cerebrovascular disorders. However, controversies persist regarding the utilization of LC in nervous system diseases, with varying effects observed across numerous mental and neurological disorders. This article primarily aims to gather and analyze database information to comprehensively summarize the therapeutic potential of LC in patients suffering from nervous system diseases while providing valuable references for further research. METHODS A comprehensive search was conducted in PubMed, Web Of Science, Embase, Ovid Medline, Cochrane Library and Clinicaltrials.gov databases. The literature pertaining to the impact of LC supplementation on neurological or psychiatric disorders in patients was reviewed up until November 2023. No language or temporal restrictions were imposed on the search. RESULTS A total of 1479 articles were retrieved, and after the removal of duplicates through both automated and manual exclusion processes, 962 articles remained. Subsequently, a meticulous re-screening led to the identification of 60 relevant articles. Among these, there were 12 publications focusing on hepatic encephalopathy (HE), while neurodegenerative diseases (NDs) and peripheral nervous system diseases (PNSDs) were represented by 9 and 6 articles, respectively. Additionally, stroke was addressed in five publications, whereas Raynaud's syndrome (RS) and cognitive disorder (CD) each had three dedicated studies. Furthermore, migraine, depression, and amyotrophic lateral sclerosis (ALS) each accounted for two publications. Lastly, one article was found for other symptoms under investigation. CONCLUSION In summary, LC has demonstrated favorable therapeutic effects in the management of HE, Alzheimer's disease (AD), carpal tunnel syndrome (CTS), CD, migraine, neurofibromatosis (NF), PNSDs, RS, and stroke. However, its efficacy appears to be relatively limited in conditions such as ALS, ataxia, attention deficit hyperactivity disorder (ADHD), depression, chronic fatigue syndrome (CFS), Down syndrome (DS), and sciatica.

Abstract
AIM To determine if children with neonatal cholestatic liver disease had concurrent and later findings on brain imaging studies that could be attributed and the cholestasis to contribute to the understanding of the impaired neuropsychological development. METHODS Ovid MEDLINE and EMBASE were searched on July 21, 2022, and updated on March 26, 2023. Studies with children under 18 years of age with neonatal cholestasis and a brain scan at the time of diagnosis or later in life were included. Excluded studies were non-English, non-human, reviews or conference abstracts. Data were extracted on demographics, brain imaging findings, treatment and outcome. The results were summarised by disease categories. Risk of bias was assessed using JBI critical appraisal tools. RESULTS The search yielded 12 011 reports, of which 1261 underwent full text review and 89 were eligible for inclusion. Haemorrhage was the most common finding, especially in children with bile duct obstruction, including biliary atresia. Some findings were resolved after liver transplantation. CONCLUSION Children with neonatal cholestasis had changes in brain imaging, which might play a role in impaired neuropsychological development, but longitudinal clinical research with structured assessment is needed to better qualify the aetiology of the impairment.

Golexanolone improves fatigue, motor incoordination and gait and memory in rats with bile duct ligation. Liver Int 2024; 44:433-445. [PMID: 38010893 DOI: 10.1111/liv.15782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 09/11/2023] [Accepted: 10/23/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND AND AIMS Many patients with the chronic cholestatic liver disease primary biliary cholangitis (PBC) show fatigue and cognitive impairment that reduces their quality of life. Likewise, rats with bile duct ligation (BDL) are a model of cholestatic liver disease. Current PBC treatments do not improve symptomatic alterations such as fatigue or cognitive impairment and new, more effective treatments are therefore required. Golexanolone reduces the potentiation of GABAA receptors activation by neurosteroids. Golexanolone reduces peripheral inflammation and neuroinflammation and improves cognitive and motor function in rats with chronic hyperammonemia. The aims of the present study were to assess if golexanolone treatment improves fatigue and cognitive and motor function in cholestatic BDL rats and if this is associated with improvement of peripheral inflammation, neuroinflammation, and GABAergic neurotransmission in the cerebellum. METHODS Rats were subjected to bile duct ligation. One week after surgery, oral golexanolone was administered daily to BDL and sham-operated controls. Fatigue was analysed in the treadmill, motor coordination in the motorater, locomotor gait in the Catwalk, and short-term memory in the Y-maze. We also analysed peripheral inflammation, neuroinflammation, and GABAergic neurotransmission markers by immunohistochemistry and Western blot. RESULTS BDL induces fatigue, impairs memory and motor coordination, and alters locomotor gait in cholestatic rats. Golexanolone improves these alterations, and this was associated with improvement of peripheral inflammation, neuroinflammation, and GABAergic neurotransmission in the cerebellum. CONCLUSION Golexanolone may have beneficial effects to treat fatigue, and motor and cognitive impairment in patients with the chronic cholestatic liver disease PBC.

Abstract
BACKGROUND Primary biliary cholangitis (PBC) is an autoimmune liver disease, whose etiology is yet to be fully elucidated. Currently, ursodeoxycholic acid (UDCA) is the only first-line drug. However, 40% of PBC patients respond poorly to it and carry a potential risk of disease progression. So, in this study, we aimed to explore new biomarkers for risk stratification in PBC patients to enhance treatment. METHODS We first downloaded the clinical characteristics and microarray datasets of PBC patients from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were identified and subjected to enrichment analysis. Hub genes were further validated in multiple public datasets and PBC mouse model. Furthermore, we also verified the expression of the hub genes and developed a predictive model in our clinical specimens. RESULTS A total of 166 DEGs were identified in the GSE79850 dataset, including 95 upregulated and 71 downregulated genes. Enrichment analysis indicated that DEGs were significantly enriched in inflammatory or immune-related process. Among these DEGs, 15 risk-related genes were recognized and further validated in the GSE119600 cohort. Then, TXNIP, CD44, ENTPD1, and PDGFRB were identified as candidate hub genes. Finally, we proceeded to the next screening with these four genes in our serum samples and developed a three-gene panel. The gene panel could effectively identify those patients at risk of disease progression, yielding an AUC of 0.777 (95% CI, 0.657-0.870). CONCLUSIONS In summary, combining bioinformatics analysis and experiment validation, we identified TXNIP, CD44, and ENTPD1 as promising biomarkers for risk stratification in PBC patients.

Abstract
BACKGROUND AND AIMS Fatigue is common in patients with advanced liver disease. We investigated fatigue and clinical outcomes among patients with advanced nonalcoholic steatohepatitis (NASH). METHODS In this study, patients with biopsy confirmed NASH and bridging fibrosis (F3) or compensated cirrhosis (F4) were followed for up to 2 years. The Chronic Liver Disease Questionnaire for Nonalcoholic Steatohepatitis (CLDQ-NASH) fatigue domain at baseline (range, 1-7; lower score indicating worse fatigue) quantified fatigue. The Cox proportional hazards model was used to study time to liver-related clinical events (progression to histologic cirrhosis or hepatic decompensation in F3, hepatic decompensation in F4). RESULTS Of the 1679 NASH patients with fibrosis, 802 had F3 and 877 had F4 (58 ± 9 years of age, 40% male, 74% type 2 diabetes). During median follow-up of 16 months (interquartile range, 14-18), 15% (n = 123) of NASH F3 patients experienced liver-related events and 3.5% (n = 31) of NASH F4 patients experienced hepatic decompensation. Mean baseline CLDQ-NASH fatigue score in F3 patients was 4.77 ± 1.36; NASH F3 patients who experienced liver-related events had lower baseline scores: 4.47 ± 1.36 vs 4.83 ± 1.35 (P = .0091). The mean fatigue score in F4 was 4.56 ± 1.44; these scores were lower in patients who decompensated in follow-up: 3.74 ± 1.31 vs 4.59 ± 1.43 (P = .0011). The association of lower fatigue scores and risk of liver-related or decompensation events was significant after adjustment for confounders (adjusted hazard ratio per 1 point in fatigue score in F3, 0.85; 95% confidence interval, 0.74-0.97; P = .02; adjusted hazard ratio in F4, 0.62; 95% confidence interval, 0.48-0.81; P = .0004). CONCLUSION Worse fatigue at baseline is associated with a higher risk of adverse clinical events in patients with NASH-related advanced fibrosis and cirrhosis.

Abstract
Patients with cholestatic liver disease, including those with primary biliary cholangitis, can experience symptoms of impaired cognition or brain fog. This phenomenon remains unexplained and is currently untreatable. Bile duct ligation (BDL) is an established rodent model of cholestasis. In addition to liver changes, BDL animals develop cognitive symptoms early in the disease process (before development of cirrhosis and/or liver failure). The cellular mechanisms underpinning these cognitive symptoms are poorly understood. Herein, the study explored the neurocognitive symptom manifestations, and tested potential therapies, in BDL mice, and used human neuronal cell cultures to explore translatability to humans. BDL animals exhibited short-term memory loss and showed reduced astrocyte coverage of the blood-brain barrier, destabilized hippocampal network activity, and neuronal senescence. Ursodeoxycholic acid (first-line therapy for most human cholestatic diseases) did not reverse symptomatic or mechanistic aspects. In contrast, obeticholic acid (OCA), a farnesoid X receptor agonist and second-line anti-cholestatic agent, normalized memory function, suppressed blood-brain barrier changes, prevented hippocampal network deficits, and reversed neuronal senescence. Co-culture of human neuronal cells with either BDL or human cholestatic patient serum induced cellular senescence and increased mitochondrial respiration, changes that were limited again by OCA. These findings provide new insights into the mechanism of cognitive symptoms in BDL animals, suggesting that OCA therapy or farnesoid X receptor agonism could be used to limit cholestasis-induced neuronal senescence.

Abstract
Hepatic encephalopathy (HE) is one of the major complications of cirrhosis, and its presence is associated with poor survival. Several risk factors for HE are well established, including age, history of HE, portosystemic shunts, or poorer liver function. In recent years, diabetes mellitus (DM) has emerged as another potential risk factor for the development of HE. This may be important for many patients, as the incidence of type 2 DM (T2DM) is increasing worldwide and, consequently, the incidence of NAFLD-related cirrhosis is rising simultaneously. In addition, DM is a critical factor in the progression of other liver diseases, such as alcohol-related liver disease. Thus, the number of patients with cirrhosis and comorbid T2DM will also increase. To date, the prevalence of DM already ranges between 22 - 40% in patients with cirrhosis. DM-associated factors that may influence the risk of HE include systemic inflammation, insulin resistance with increased muscle protein breakdown as well as autonomic dysfunction with prolonged intestinal transit time and small intestinal bacterial overgrowth. Currently, the evidence for an association between DM and both minimal and overt HE is weak and it seems likely that only poor glycemic control has an impact on HE risk. In addition, there are some early signs indicating that DM may impair the response of patients with HE to pharmacological therapies such as rifaximin. Thus, improvements in the management of glycemic control may be a candidate future target to reduce the risk of HE. In this concise review, we summarize the current evidence on the association between DM and HE and its potential future implications.

Abstract
BACKGROUND & AIMS Cirrhotic cardiomyopathy is a major complication and cause of morbidity in end-stage primary biliary cholangitis (PBC). However, it is unclear whether there is clinically silent myocardial involvement at the early stage of PBC before cirrhosis and cardiac manifestations. This prospective, three-center, multi-modality cardiac imaging study on the early identification of myocardial impairment in PBC (EARLY-MYO-PBC) was designed to identify silent myocardial impairment in PBC patients without cardiac manifestations. METHODS A total of 112 subjects (56 with PBC and 56 age- and sex-matched controls) undergoing cardiovascular magnetic resonance (CMR) were enrolled. Demographic, serologic, and cardiac imaging data were prospectively collected. All participants had no cardiac discomfort or previous heart disease and had normal electrocardiographic findings. RESULTS Subclinical myocardial involvement, as evidenced by cardiac morphologic, functional, and tissue characterization changes on CMR, including hyperdynamic left ventricular (LV) ejection fraction (median, 75% in PBC patients vs 69% in controls, P = .029), subclinical myocardial edema by T2-short tau inversion recovery (21% vs 2% in controls, P = .001), elevated extracellular matrix indices (30% vs 26% in controls, P < .001), and impaired myocardial viability by positive late gadolinium enhancement (LGE) (36%), was detected in PBC patients. Importantly, a mid-wall "stripe" at the LV septum was identified as a PBC-specific LGE pattern that differs from other known cardiomyopathies. In multivariate analysis, gp210 positivity (odds ratio [OR] = 9.909, P = .010), lower hemoglobin (OR = 0.919, P = .004), and body mass index (OR = 0.638, P = .005) were independent predictors of cardiac abnormalities in PBC. CONCLUSIONS This study demonstrates clinically silent cardiac impairment with specific CMR patterns in PBC, allowing optimal screening for early myocardial impairment and potentially timely therapies.

Abstract
BACKGROUND AND AIMS Neuropsychiatric symptoms in hepatitis C (HCV) patients resemble those of patients with autoimmune hepatitis (AIH) or primary biliary cholangitis (PBC), whilst the mechanisms behind them are unknown. Here we looked for cerebral metabolic and/or microstructural alterations in patients with HCV, AIH or PBC as possible causes behind these symptoms. METHODS Patients with HCV infection (n = 17), AIH (n = 14) or PBC (n = 11) and age-adjusted healthy controls (n = 18) underwent brain magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS) and psychometric assessment of memory and attention. Brain relative proton density (PD) and T2 relaxation time (T2) were determined in 17 regions of interest (ROIs), as were the concentrations of N-acetyl-aspartate, choline, creatine, myo-inositol and glutamine + glutamate in frontal- (fWM) and parietal white matter (pWM). One-way analysis of variance and Kruskal-Wallis tests were used for group comparison. Correlations between altered neuropsychological findings and MRI/MRS observations were estimated with the Spearman ρ test. RESULTS HCV, AIH and PBC patients revealed similar alterations in brain PD and metabolites compared to controls: significantly decreased PD in 7/17 ROIs in the HCV group, 16/17 ROIs in the PBC group and 14/17 ROIs in the AIH group, significantly increased N-acetyl-aspartate in fWM in all patients, significantly increased choline in the PBC group in both fWM and pWM, in the AIH group only in pWM and with a trend in the HCV group in pWM. Correlation analysis did not reveal significant associations between MRI/MRS alterations and neuropsychological dysfunction. CONCLUSION The findings suggest similar pathophysiological mechanisms behind neuropsychiatric symptoms associated with HCV infection, AIH and PBC.

Neurosteroid Activation of GABA-A Receptors: A Potential Treatment Target for Symptoms in Primary Biliary Cholangitis? Can J Gastroenterol Hepatol 2022; 2022:3618090. [PMID: 36523650 PMCID: PMC9747297 DOI: 10.1155/2022/3618090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 11/07/2022] [Accepted: 11/09/2022] [Indexed: 12/12/2022] Open
Abstract
Background and Aims A third of patients with primary biliary cholangitis (PBC) experience poorly understood cognitive symptoms, with a significant impact on quality of life (QOL), and no effective medical treatment. Allopregnanolone, a neurosteroid, is a positive allosteric modulator of gamma-aminobutyricacid-A (GABA-A) receptors, associated with disordered mood, cognition, and memory. This study explored associations between allopregnanolone and a disease-specific QOL scoring system (PBC-40) in PBC patients. Method Serum allopregnanolone levels were measured in 120 phenotyped PBC patients and 40 age and gender-matched healthy controls. PBC subjects completed the PBC-40 at recruitment. Serum allopregnanolone levels were compared across PBC-40 domains for those with none/mild symptoms versus severe symptoms. Results There were no overall differences in allopregnanolone levels between healthy controls (median = 0.03 ng/ml (IQR = 0.025)) and PBC patients (0.031 (0.42), p = 0.42). Within the PBC cohort, higher allopregnanolone levels were observed in younger patients (r (120) = -0.53, p < 0.001) but not healthy controls (r (39) = -0.21, p = 0.21). Allopregnanolone levels were elevated in the PBC-40 domains, cognition (u = 1034, p = 0.02), emotional (u = 1374, p = 0.004), and itch (u = 795, p = 0.03). Severe cognitive symptoms associated with a younger age: severe (50 (12)) vs. none (60 (13); u = 423 p = 0.001). Conclusion Elevated serum allopregnanolone is associated with severe cognitive, emotional, and itch symptoms in PBC, in keeping with its known action on GABA-A receptors. Existing novel compounds targeting allopregnanolone could offer new therapies in severely symptomatic PBC, satisfying a significant unmet need.

Abstract
BACKGROUND Fatigue affects 50% of primary biliary cholangitis patients and is severe in approximately 20%, significantly affecting quality of life. The pathogenesis of fatigue in primary biliary cholangitis is poorly understood. This study aimed to explore subgroups of fatigue to support targeting of selected groups in future clinical trials. METHODS Data were derived from the UK-PBC cohort. Participants completed the PBC-40, Hospital Anxiety and Depression Score, Epworth Sleepiness Scale, and Orthostatic Grading Scale for symptoms assessment. Fatigue and cognitive symptoms were regarded as clinically significant if they exceeded the previously defined cutoff for "moderate" symptom. RESULTS Of 2002, patients for whom full PBC-40, fatigue, and cognitive symptom domain scores were available, 1203 (60%) had significant fatigue and 730 (36%) had significant cognitive symptoms. Among the 1203 patients with significant fatigue, 663 (55%) also had significant cognitive symptoms (termed fatigue with cognitive symptoms) with a significant linear association between the fatigue and cognitive symptom severity. "Fatigue with cognitive symptoms" patients were younger and more likely to have severe fatigue. They also experienced greater social and emotional impact. CONCLUSIONS Fatigue in PBC is complex, and there has been no progress to date in identifying therapies able to improve it. One factor in slow progress may be the heterogeneity of patients describing fatigue complicating effective cohort selection for clinical trials. This study has identified potential discrete subgroups of fatigued patients with and without cognitive symptoms. The group of patients expressing "fatigue with cognitive symptoms" was homogenous and may represent a coherent cohort for clinical trials.

Abstract
Introduction: Patients with cholestatic diseases may develop fatigue and cognitive symptoms. The impact of symptom burden may be significant in some patients. To date, there are no effective pharmacological therapies to improve cognitive symptoms or fatigue in cholestasis and we are wholly reliant on supportive approaches. Area covered: This review provides an overview of cognitive symptoms and fatigue in the cholestatic liver disease primary biliary cholangitis (PBC), including pathophysiology and our approach to the management of these symptoms. Expert opinion: The impact of fatigue and cognitive symptoms on the perceived quality of life can be profound for patients with PBC. The pathophysiology of these symptoms is complex and poorly understood, making the development of therapeutic trials of symptom-directed therapies challenging. The current recommended management for fatigue and cognitive symptoms is mainly supportive.

Abstract
Primary biliary cholangitis (PBC) causes chronic and persistent cholestasis in the liver, eventually resulting in cirrhosis and hepatic failure without appropriate treatment. PBC mainly develops in middle-aged women, but it is also common in young women and men. PBC is considered a model of autoimmune disease because of the presence of disease-specific autoantibodies, that is, antimitochondrial antibodies (AMAs), intense infiltration of mononuclear cells into the bile ducts, and a high prevalence of autoimmune diseases such as comorbidities. Histologically, PBC is characterized by degeneration and necrosis of intrahepatic biliary epithelial cells surrounded by a dense infiltration of mononuclear cells, coined as chronic non-suppurative destructive cholangitis, which leads to destructive changes and the disappearance of small- or medium-sized bile ducts. Since 1990, early diagnosis with the detection of AMAs and introduction of ursodeoxycholic acid as first-line treatment has greatly altered the clinical course of PBC, and liver transplantation-free survival of patients with PBC is now comparable to that of the general population.

Abstract
Hepatic encephalopathy (HE) is a frequent and serious complication of both chronic liver disease and acute liver failure. HE manifests as a wide spectrum of neuropsychiatric abnormalities, from subclinical changes (mild cognitive impairment) to marked disorientation, confusion and coma. The clinical and economic burden of HE is considerable, and it contributes greatly to impaired quality of life, morbidity and mortality. This review will critically discuss the latest classification of HE, as well as the pathogenesis and pathophysiological pathways underlying the neurological decline in patients with end-stage liver disease. In addition, management strategies, diagnostic approaches, currently available therapeutic options and novel treatment strategies are discussed.

Abstract
Chronic fatigue, mood alterations and cognitive impairment are frequent accessory symptoms of HCV infection. Fatigue and mood alterations have also been observed in autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC), but not in hepatitis B virus (HBV)-infection, thus indicating an autoimmune response as possible cause of HCV infection-associated encephalopathy. Data, however, are sparse. This study aimed to prove that HCV patients feature similar to those with autoimmune liver disease but contrary to HBV patients regarding neuropsychiatric symptoms. A total of 132 noncirrhotic patients (HCV: 46, HBV: 22, AIH: 27, PBC: 29, AIH/PBC: 8) completed questionnaires addressing the domains mentioned above. Eighty-eight underwent a comprehensive neuropsychological assessment. Patient groups were compared among each other and to 33 healthy controls. Fatigue, anxiety and depression scores were significantly increased, and the SF-36 mental score significantly decreased in all patient groups compared to controls. Fatigue was significantly more pronounced in HCV than in HBV patients. HCV patients scored significantly worse than HBV patients but not AIH and PBC patients in the SF-36. HCV, AIH and PBC but not HBV patients did significantly worse than controls in word learning. Recognition of words was impaired in HCV, AIH and PBC patients and recognition of figures in HCV patients, exclusively (P ≤ 0.002). HCV patients did also worse than controls and HBV patients concerning alertness and working memory (P ≤ 0.001). The neuropsychiatric profiles of HCV patients are similar to those of AIH and PBC patients but differ from those of HBV patients, suggesting an autoimmune response as a possible cause for these differences.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease that results in substantial morbidity and mortality with many unanswered clinical and research questions. Improved understanding of disease pathogenesis, including the extra-hepatic manifestations of AIH, may allow targeted treatments with greater efficacy and fewer associated adverse events. AIM To identify the spectrum of unanswered clinical and research questions facing care providers in the management of patients with autoimmune hepatitis (AIH). METHODS The International Autoimmune Hepatitis Group initiated a series of research workshops to start to address these questions. Key issues were discussed in small group sessions with collation of all discussions to be summarised in this manuscript. RESULTS Key issues were identified as: the need for better understanding of disease pathogenesis, standardisation of the methods and assays used to evaluate autoantibodies in AIH, refinement of the histopathological criteria for "typical" or "compatible" AIH, focus on the interaction with non-alcohol related fatty liver disease, how to treat acute severe AIH, better assessment of quality of life in adults and paediatrics, standardising use of standard, third-line and experimental therapies in AIH and search for biomarkers early in the disease course that predict outcome. CONCLUSION This workshop has outlined the key unanswered clinical and research questions to help to define the research agenda in AIH.

Abstract
Fatigue has a significant effect on the condition of patients with liver disease. Ademethionine is considered one of the most promising drugs for its treatment. Aim. To systematize the published data on the treatment of hepatogenic fatigue with аdemethionine. Materials and methods. Search was performed using databases PubMed, EMBASE, Embase®, Medline®, eLIBRARY.ru, published in 1952-2018. Results and discussion. 16 articles were found on the use of ademethionine in liver diseases and the assessment of the dynamics of the symptom of fatigue, including 1 double-blind, randomized, placebo-controlled study, 3 open randomized studies; most of the works were multicenter open observation programs. The studies included 3238 patients (of which 2820 were included in the final data analysis) and a wide range of liver diseases: alcoholic liver disease, nonalcoholic fatty liver disease, primary biliary cholangitis, primary sclerosing cholangitis, cirrhosis of different causes, viral hepatitis, drug-induced liver injury. Different doses, routes of administration of аdemethionine and the duration of the course were used. Conclusions. Ademethionine, regardless of the route of administration, is effective in the treatment of fatigue due to different liver disease in the short and long term. The dose-dependent effect of the drug and the possibility of maintaining post-effect after end of the treatment course should be assumed, but this requires further study in randomized clinical trials.

Abstract
The management of fatigue associated with chronic liver disease is a complex and major clinical challenge. Although fatigue can complicate many chronic diseases, it is particularly common in diseases with an inflammatory component. Fatigue can have both peripheral (i.e., neuromuscular) and central (i.e., resulting from changes in neurotransmission within the brain) causes. However, fatigue in chronic liver disease has strong social/contextual components and is often associated with behavioural alterations including depression and anxiety. Given the increasing awareness of patient-reported outcomes as important components of treatment outcomes and clinical research, there is a growing need to better understand and manage this poorly understood yet debilitating symptom. Although several pathophysiological mechanisms for explaining the development of fatigue have been generated, our understanding of fatigue in patients with chronic liver disease remains incomplete. A better understanding of the pathways and neurotransmitter systems involved may provide specific directed therapies. Currently, the management of fatigue in chronic liver disease can involve a combined use of methods to beneficially alter behavioural components and pharmacological interventions, of which several treatments have potential for the improved management of fatigue in chronic liver disease. However, evidence and consensus are lacking on the best approach and the most appropriate biochemical target(s) whilst clinical trials to address this issue have been few and limited by small sample size. In this review, we outline current understanding of the impact of fatigue and related symptoms in chronic liver disease, discuss theories of pathogenesis, and examine current and emerging approaches to its treatment.

Abstract
Background In primary biliary cholangitis (PBC) fatigue is a major clinical challenge of unknown etiology. By demonstrating that fatigue in PBC is associated with an impaired cognitive performance, previous studies have pointed out the possibility of brain abnormalities underlying fatigue in PBC. Whether structural brain changes are present in PBC patients with fatigue, however, is unclear. To evaluate the role of structural brain abnormalities in PBC patients severely affected from fatigue we, therefore, performed a case-control cerebral magnetic resonance imaging (cMRI) study and correlated changes of white and grey brain matter with the cognitive and attention performance. Methods 20 female patients with PBC and 20 female age-matched controls were examined in this study. The assessment of fatigue, psychological symptoms, cognitive and attention performance included clinical questionnaires, established cognition tests and a computerized test battery of attention performance. T1-weighted cMRI and diffusion tensor imaging (DTI) scans were acquired with a 3 Tesla scanner. Structural brain alterations were investigated with voxel-based morphometry (VBM) and DTI analyses. Results were correlated to the cognitive and attention performance. Results Compared to healthy controls, PBC patients had significantly higher levels of fatigue and associated psychological symptoms. Except for an impairment of verbal fluency, no cognitive or attention deficits were found in the PBC cohort. The VBM and DTI analyses revealed neither major structural brain abnormalities in the PBC cohort nor correlations with the cognitive and attention performance. Conclusions Despite the high burden of fatigue and selected cognitive deficits, the attention performance of PBC patients appears to be comparable to healthy people. As structural brain alterations do not seem to be present in PBC patients with fatigue, fatigue in PBC must be regarded as purely functional. Future studies should evaluate, whether functional brain changes underlie fatigue in PBC.
