Autoimmune hepatitis exerts a profound, negative effect on health-related quality of life: A prospective, single-centre study

EASL Clinical Practice Guidelines on the management of autoimmune hepatitis

Autoimmune hepatitis (AIH) is a chronic liver disease of unknown aetiology which may affect any patient irrespective of age, sex, and ethnicity. At baseline, the clinical spectrum of the disease varies largely from asymptomatic cases to acute liver failure with massive hepatocyte necrosis. The aim of these EASL guidelines is to provide updated guidance on the diagnosis and management of AIH both in adults and children. Updated guidance on the management of patients with variants and specific forms of AIH is also provided, as is detailed guidance on the management of AIH-associated cirrhosis, including surveillance for portal hypertension and hepatocellular carcinoma, as well as liver transplantation in decompensated cirrhosis.

Clinical management of autoimmune liver diseases: juncture, opportunities, and challenges ahead

The three major autoimmune liver diseases are autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC).These conditions are assumed to result from a breakdown in immunological tolerance, which leads to an inflammatory process that causes liver damage.The self-attack is started by T-helper cell-mediated identification of liver autoantigens and B-cell production of autoantibodies,and it is maintained by a reduction in the number and activity of regulatory T-cells.Infections and environmental factors have been explored as triggering factors for these conditions, in addition to a genetic predisposition.Allelic mutations in the HLA locus have been linked to vulnerability, as have relationships with single nucleotide polymorphisms in non-HLA genes.Despite the advances in the management of these diseases, there is no curative treatment for these disorders, and a significant number of patients eventually progress to an end-stage liver disease requiring liver transplantation.In this line, tailored immune-therapeutics have emerged as possible treatments to control the disease.In addition, early diagnosis and treatment are pivotal for reducing the long-lasting effects of these conditions and their burden on quality of life.Herein we present a review of the etiology, clinical presentation, diagnosis, and challenges on ALDs and the feasible solutions for these complex diseases.

Quo vadis autoimmune hepatitis? - Summary of the 5th international autoimmune hepatitis group research workshop 2024

Autoimmune hepatitis (AIH) is a rare chronic liver disease with an increasing incidence in many countries. Chronic autoimmune responses against the liver can cause hepatic and extrahepatic symptoms, decreased quality of life and reduced liver transplant-free survival if inadequately treated. Although standard treatment with corticosteroids and thiopurines improves the life expectancy of patients with AIH, remission rates and tolerability are generally overestimated and the development of alternative first-line and salvage therapies has been disappointingly slow compared to in rheumatological diseases or inflammatory bowel disease. Other gaps include the lack of disease-specific diagnostic markers for AIH. Similarly, the new entity of drug-induced autoimmune-like hepatitis underscores the need to re-evaluate previous diagnostic criteria. The International AIH Group (IAIHG) has initiated a series of research workshops over the last decade to promote the identification of research gaps and subsequently improve the pace of scientific progress by stimulating collaboration between expert centres. This review reports on the results of the 5th Research Workshop, held in Hannover, Germany in June 2024, and summarises the progress made since the 4th Workshop in 2022. Patient representatives from the European Reference Network (ERN) Rare Liver Youth Panel participated in the workshop. The specific objectives of this year's 5th Workshop were: (1) To further improve diagnostics. (2) Initiate clinical trials including knowledge transfer on drugs from extrahepatic immune-mediated diseases, including B cell-depleting CAR T cells. (3) Utilisation of multi-omics approaches to improve the understanding of disease pathogenesis. (4) Application of machine learning-based approaches established in oncology or transplantation medicine to improve diagnosis and outcome prediction in AIH.

Depression and anxiety management in cirrhosis

Depressive and anxiety symptoms are more prevalent in patients with cirrhosis compared to the general population. Between 2009 and 2019, the prevalence of depression in cirrhosis increased by 80%, while the prevalence of generalized anxiety disorder increased by over 400%. When present, anxiety and depression are linked to lower health-related quality of life, more severe symptoms (eg, fatigue), and poorer response to medical treatment. Screening instruments for depression and anxiety have shown acceptable validity in patients with cirrhosis. However, the diagnosis of depression and anxiety disorder remains challenging in this population and should follow the established criteria for general populations. Treatment interventions are numerous and include patient education and support around liver disease, pharmacological agents, and psychotherapy. Antidepressants are the treatment of choice for patients with depressive or anxiety disorder and cirrhosis. However, consideration must be given to dose adjustment and choice of agent due to changes in their metabolism in patients with liver disease. Psychotherapy may be used as a stand-alone therapy or concomitantly with pharmacotherapy. The high prevalence and complexity of depressive and anxiety symptoms in patients with cirrhosis support the integrated care approach in which patients are cared for by multidisciplinary teams.

Perceived Stigma in Patients with Autoimmune Hepatitis

Perceived stigma (PS) adversely impacts psychosocial and disease outcomes in patients with chronic liver diseases (CLD), and those with autoimmune hepatitis (AIH) may be at risk for PS given inaccurate assumptions about the origin of their diagnosis. The aims of the current study are to describe the frequency of PS in patients with AIH, compare rates of PS in AIH to rates of PS in primary biliary cholangitis (PBC) and CLD, and examine demographic correlates of PS. 262 adults with AIH (95% female, Mage = 51.53 years) completed online questionnaires on demographics, disease information, and PS. 54-68% reported PS with themes of selective disclosure, non-disclosure, or hiding diagnosis. PS was higher in those with AIH compared to those with PBC, but lower than those with various CLD. Age was inversely related to PS. Given the results, provider screening of PS and integration of clinical health psychologists may be helpful for identifying PS in patients with AIH.

Zinc Supplementation and an Improved Quality of Life in Patients with Autoimmune Hepatitis

Objecive Patients with autoimmune hepatitis (AIH) reportedly have an impaired quality of life (QOL), mainly due to depression, even during remission. In addition, hypozincaemia has been demonstrated in patients with chronic liver disease, including AIH, and is known to be related to depression. Corticosteroids are known to cause mental instability. We therefore investigated the longitudinal association between zinc supplementation and changes in the mental status among AIH patients treated with corticosteroids. Materials This study enrolled 26 patients with serological remission of AIH routinely treated at our facility after excluding 15 patients who either discontinued polaprezinc (150 mg/day) within 24 months or interrupted treatment. Two questionnaires, the Chronic Liver Disease Questionnaire (CLDQ) and SF-36, were adopted to evaluate the QOL before and after zinc supplementation. Results Serum zinc levels were significantly elevated after zinc supplementation (p<0.0001). The CLDQ worry subscale significantly improved after zinc supplementation (p=0.017), but none of the SF-36 subscales was affected. Multivariate analyses demonstrated that daily prednisolone dosing was inversely related to both the CLDQ worry domain score (p=0.036) and the SF-36 mental health component (p=0.031). There was a significant negative correlation between the changes in the daily steroid dose and the CLDQ worry domain scores before and after zinc supplementation (p=0.006). No serious adverse events occurred during the observation period. Conclusion Zinc supplementation safely and efficiently improved mental impairment, possibly caused by continuous treatment with corticosteroids, in patients with AIH.

Improving quality of life in patients with rare autoimmune liver diseases by structured peer-delivered support (Q.RARE.LI): study protocol for a transnational effectiveness-implementation hybrid trial

BACKGROUND

Psychosocial support is a crucial component of adequate rare disease care, but to date psychosocial support needs of this patient population are insufficiently met. Within Q.RARE.LI, we strive to evaluate the effectiveness of a structured, transdiagnostic, and location-independent psychosocial support intervention in routine care of patients with rare autoimmune liver diseases in five countries and prepare its implementation.

METHODS

Within an effectiveness-implementation hybrid trial, we aim to a) investigate the effectiveness of the intervention in routine care in five diverse healthcare systems and b) assess implementation outcomes, examine and prepare the implementation context, and develop country-specific implementation strategies. To assess effectiveness, we will include N = 240 patients with rare autoimmune liver diseases. Within a two-armed randomized controlled trial (allocation ratio 1:1), we will compare structured and peer-delivered psychosocial support in addition to care-as-usual (CAU) with CAU alone. Outcomes will be assessed via electronic database entry prior to intervention, directly after, and at a three-month follow-up. Our primary effectiveness outcome will be mental health-related quality of life at post-assessment. Secondary outcomes include depression and anxiety severity, perceived social support, helplessness, and disease acceptance. Implementation outcomes will be assessed within a mixed-methods process evaluation. In a quantitative cross-sectional survey, we will examine perceived acceptability and feasibility in patients, peer-counselors, and healthcare providers involved in delivery of the intervention. In qualitative focus groups, we will analyze the implementation context and determine barriers and facilitators for implementation with different stakeholders (patients and/or representatives, peer-counselors, healthcare providers, health insurers). Based on these results, we will derive country-specific implementation strategies and develop a concrete implementation plan for each country.

DISCUSSION

The intervention is expected to help patients adjust to their disease and improve their mental quality of life. The transdiagnostic and location-independent program has the potential to reach patients for psychosocial support who are usually hard to reach. By preparing the implementation in five countries, the project can help to make low-threshold psychosocial support available to many patients with rare diseases and improve comprehensive healthcare for an often neglected group.

Health-related quality of life and symptoms in autoimmune liver diseases

Assessment of Health-Related Quality of Life (HRQoL) has emerged as an important tool in the evaluation of both the well-being of patients and the results of their clinical management. Over the years, a large number of questionnaires focusing on various aspects of quality of life have been developed. They are frequently divided into generic questionnaires, which can be used under various conditions, disease-specific and symptom-specific questionnaires. Autoimmune liver diseases, such as autoimmune hepatitis, primary sclerosing cholangitis, or primary biliary cirrhosis, comprise a group of rare liver conditions (i.e. affecting fewer than 5 in 10,000 people in the general population). Unfortunately, HRQoL has not been well-studied in this group of patients. In this review, we comprehensively summarize the data available in the literature on HRQoL in these conditions, emphasizing the important role that quality of life plays in the successful management of such patients.

Open challenges in the management of autoimmune hepatitis

Autoimmune hepatitis (AIH) is a rare autoimmune disease of the liver with many open questions as regards its etiopathogenesis, natural history and clinical management. The classical picture of AIH is chronic hepatitis with fluctuating elevation of serum transaminases and Immunoglobulin G levels, the presence of circulating autoantibodies and typical histological features. However, atypical presentations do occur and are not well captured by current diagnostic scores, with important consequences in terms of missed diagnoses and delayed treatments. AIH is treated with corticosteroids and immunosuppressive drugs but up to 40% of patients do not achieve full biochemical response and are at risk of progressing to cirrhosis and liver failure. Moreover, standard therapies are associated by significant side-effects which may impair the quality of life of patients living with AIH. However, advances in the understanding of the underlying immunology of AIH is raising the prospect of novel therapies and optimization of existing therapeutic approaches to reduce side-effect burdens and potentially restore immunological tolerance. In this review we outlined the clinical characteristics, etiopathogenesis and management of AIH and current challenges in the diagnosis and management of AIH and provided evidence underlying the evolution of diagnostic and clinical management protocols.

Diagnosis and management of autoimmune hepatitis

Autoimmune hepatitis is an inflammatory disease of the liver of unknown cause that may progress to liver cirrhosis and end stage liver failure if diagnosis is overlooked and treatment delayed. The clinical presentation is often that of acute hepatitis, sometimes very severe; less frequently, it can be insidious or completely asymptomatic. The disease can affect people of any age and is more common in women; its incidence and prevalence seem to be on the rise worldwide. An abnormal immune response targeting liver autoantigens and inducing persistent and self-perpetuating liver inflammation is the pathogenic mechanism of the disease. A specific set of autoantibodies, increased IgG concentrations, and histological demonstration of interface hepatitis and periportal necrosis are the diagnostic hallmarks of autoimmune hepatitis. Prompt response to treatment with corticosteroids and other immunomodulatory drugs is almost universal and supports the diagnosis. The aims of treatment are to induce and maintain long term remission of liver inflammation. Treatment can often even reverse liver fibrosis, thus preventing progression to advanced cirrhosis and its complications. Most patients need lifelong maintenance therapy, and repeated follow-up in experienced hands improves the quality of care and quality of life for affected patients.

Confidence in treatment is contributing to quality of life in autoimmune liver diseases. The results of ERN RARE-LIVER online survey

BACKGROUND AND AIMS

Autoimmune liver diseases (AILDs) are associated with impaired health-related quality of life (HrQoL). The aim of this project was to identify potentially modifiable factors related to HrQoL in a large transnational cohort of patients with AILDs.

METHODS

A cross-sectional online survey was conducted on patients with autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) or primary sclerosing cholangitis from 15 European countries. HrQoL was measured with EQ-5D-5L and EQ visual analogue scale (EQ-VAS) and analysed in relation to demographic, psychosocial, disease- and treatment-related factors. A Patient Health Questionnaire-2 score >3 indicated relevant depression. Multivariable linear regression analyses were used to identify potentially modifiable factors associated with HrQoL and confidence in treatment whilst adjusting for known confounders.

RESULTS

A group of 1178 European patients (79% female, mean age 48 ± 14 years) participated in the study. HrQoL was impaired in all three diseases (mean EQ-5D-5L = 0.75, mean EQ VAS = 68.9), most markedly in PBC (mean EQ-5D-5L = 0.73, mean EQ-VAS = 66.2). Relevant depression, which was detected in 17% of patients, was prominently associated with impaired HrQoL. In the regression analysis, treatment confidence was identified as an important modifiable factor positively contributing to HrQoL. This influence was observable even after adjusting for other covariates including depression. Management in a transplant centre, treatment with azathioprine in AIH, and with ursodeoxycholic acid in PBC, was associated with increased treatment confidence. Finally, improved patient-physician relationships contributed to treatment confidence.

CONCLUSION

Treatment confidence is a relevant modifiable determinant of HrQoL and should be further investigated to improve the standards of care for patients with AILDs.

Patient Priorities in Autoimmune Hepatitis: The Need for Better Treatments, More Education and Challenging Stigma

BACKGROUND

Data show that patients with autoimmune hepatitis have significantly reduced quality-of-life and that corticosteroids carry marked side effects.

AIMS

This study explored patients' experiences of autoimmune hepatitis and its treatments; key aspects for developing safe and effective new approaches to therapy.

METHODS

An anonymised, internet-based survey collected data including patient demographics, treatments, side-effects, impact on day-to-day life, sources of support and attitudes towards autoimmune hepatitis between December 2019-January 2020. Semi-structured interviews were conducted with 13 patients to further explore their support networks, treatment experiences and health priorities. Descriptive and quantitative analyses were undertaken using R and free text responses were subject to thematic analysis.

RESULTS

In total, 270 survey responses were received (median age 55 years and 94% female). Perceived medication side-effects were reported by 66% (169/257) and 73% responded negatively about their experience of corticosteroids. The majority (62·3% [(109/175]) would 'definitely' or 'probably' consider clinical trial participation to improve their care. Only 18·7% (31/166) reported access to a specialist liver nurse and nearly half were involved in support groups. Interview and survey data suggested that major issues were stigma, loss of control and fatigue.

CONCLUSIONS

This study provides insights into the realities of living with autoimmune hepatitis with clear issues around lack of support networks, need for patient empowerment and stigma surrounding liver disease. Patient priorities are better therapies to slow disease progression, avoiding corticosteroids and minimising side-effects. Patient willingness to participate in trials suggests that they are achievable provided they have the right design and clinical endpoints.

Overlooked Symptoms in Autoimmune Hepatitis Negatively Impact Many Facets of Life

BACKGROUND

Significant reduction in quality of life among patients with autoimmune hepatitis (AIH) patients has been observed in several studies. While acute symptoms associated with AIH have been well described, little is known about the overall impact of living with AIH on patients' quality of life. The aim of this qualitative descriptive study was to describe the impact of AIH and associated symptoms on quality of life from the perspectives of patients living with AIH.

METHODS

Patients from Autoimmune Hepatitis Association support groups were recruited to participate in one of five online focus groups conducted between August and September 2020. After enrollment, patients were asked to complete a brief demographic and disease history questionnaire. A single moderator conducted interviews with each group guided by seven questions focused on the impact of AIH on the participants' quality of life. Each session was recorded, transcribed, and verified. Content analysis was used to summarize the participants' responses.

RESULTS

The participants' discussed three overarching topics: (a) symptoms of AIH and medication side effects, (b) the impact the disease and symptoms/side effects on five domains of quality of life (work life, relationships with friends and family, social life, leisure activities, and diet and exercise) and (c) interactions with healthcare providers and recommendations for future research.

CONCLUSIONS

Living with AIH can have profound effects on patients' quality of life in several domains. Healthcare providers and the AIH research community should focus on developing further strategies that can improve the quality of life in persons suffering from AIH.

Anxiety and Its Influencing Factors in Patients With Drug-Induced Liver Injury

Objective

This study aims to investigate anxiety and its influencing factors in patients with drug-induced liver injury (DILI).

Materials and Methods

Ninety-four patients with DILI were enrolled and evaluated with a self-rating anxiety scale (SAS). According to the anxiety score, they were divided into four groups: the non-anxiety, mild anxiety, moderate anxiety, or severe anxiety groups, and the scores were analyzed based on demographic and biochemical indicators.

Results

Of the 94 patients with DILI, 63 did not have anxiety and 31 had anxiety (32.9%), of which 27 had mild, 3 had moderate, and 1 had severe anxiety. There were no statistically significant differences in gender, age, occupation, and level of education between the groups (F = 1.42, H = 2.361, H = 6.751, H = 1.796, and P > 0.05); anxiety score and degree of anxiety between the types of drugs that led to the liver injury (H = 0.812, H = 1.712, and P > 0.05); anxiety score between the different degrees of liver injury (H = 2.836, H = 4.957, P > 0.05); or length of hospital stay or prognosis between the degrees of anxiety (F = 1.487, H = 0.761, P > 0.05). However, there were statistically significant differences in the degree of anxiety between different degree and types of liver injury (H = 7.981, H = 8.208, P < 0.05).

Conclusion

Patients with DILI may have anxiety, especially mild anxiety. The occurrence of anxiety in patients with DILI is not related to gender, age, occupation, or level of education but may be related to the degree and type of liver injury. Anxiety has no impact on the length of stay in hospital or the prognosis of the DILI. These findings may contribute to the development of management strategies for patients with DILI.

Systematic review of response criteria and endpoints in autoimmune hepatitis by the International Autoimmune Hepatitis Group

BACKGROUND & AIMS

Autoimmune hepatitis (AIH) has been well characterised and codified through the development of diagnostic criteria. These criteria have been adapted and simplified and are widely used in clinical practice. However, there is a need to update and precisely define the criteria for both treatment response and treatment.

METHODS

A systematic review was performed and a modified Delphi consensus process was used to identify and redefine the response criteria in autoimmune hepatitis.

RESULTS

The consensus process initiated by the International Autoimmune Hepatitis Group proposes that the term 'complete biochemical response' defined as 'normalization of serum transaminases and IgG below the upper limit of normal' be adopted to include a time point at 6 months after initiation of treatment. An insufficient response by 6 months was a failure to meet the above definition. Non-response was defined as '<50% decrease of serum transaminases within 4 weeks after initiation of treatment'. Remission is defined as liver histology with a Hepatitis Activity Index <4/18. Intolerance to treatment was agreed to stand for 'any adverse event possibly related to treatment leading to potential drug discontinuation'.

CONCLUSIONS

These definitions provide a simple and reproducible framework to define treatment response and non-response, irrespective of the therapeutic intervention. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable inter-study comparisons. Future prospective database studies are needed to validate these endpoints.

LAY SUMMARY

Consensus among international experts on response criteria and endpoints in autoimmune hepatitis is lacking. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable the comparison of results between clinical trials. Therefore, the International Autoimmune Hepatitis Group (IAIHG) herein presents a statement on 5 agreed response criteria and endpoints: complete biochemical response, insufficient response, non-response, remission, and intolerance to treatment, which can be used to guide future reporting.

Health-related quality of life in autoimmune hepatitis

Autoimmune hepatitis (AIH) is a severe chronic autoimmune disease and has a significant impact on the patient's quality of life, in particular regarding psychological problems such as anxiety and depression. Consistent evidence on which patient-related, disease-related or physician-related factors cause health-related quality of life (HRQoL) impairment in patients with AIH is lacking. Current studies on HRQoL in AIH are mainly single-centered, comprising small numbers of patients, and difficult to compare because of the use of different questionnaires, patient populations, and cutoff values. Literature in the pediatric field is sparse, but suggests that children/adolescents with AIH have a lower HRQoL. Knowledge of HRQoL and cohesive factors in AIH are important to improve healthcare for AIH patients, for example by developing an AIH-specific chronic healthcare model. By recognizing the importance of quality of life beyond the concept of biochemical and histological remission, clinicians allow us to seek enhancements and possible interventions in the management of AIH, aiming at improved health.

Quality of life and unmet needs in patients with chronic liver disease: A mixed-method systematic review

Background & Aims

In an attempt to uncover unmet patient needs, this review aims to synthesise quantitative and qualitative studies on patients’ quality of life and their experience of having liver disease.

Methods

Three databases (CINAHL, Embase, and PubMed) were searched from January 2000 to October 2020. The methodological quality and data extraction of both quantitative and qualitative studies were screened and appraised using Joanna Briggs Institute instruments for mixed-method systematic reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A convergent, integrated approach to synthesis and integration was used. Studies including patients with autoimmune and cholestatic liver disease, chronic hepatitis B and C, non-alcoholic fatty liver disease and non-alcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma were considered.

Results

The searches produced 5,601 articles, of which 95 (79 quantitative and 16 qualitative) were included in the review. These represented studies from 26 countries and a sample of 37,283 patients. The studies showed that patients´ quality of life was reduced. Unmet needs for information and support and perceived stigmatisation severely affected patients’ quality of life.

Conclusions

Our study suggests changes to improve quality of life. According to patients, this could be achieved by providing better education and information, being aware of patients’ need for support, and raising awareness of liver disease among the general population to reduce misconceptions and stigmatisation.

Registration number

PROSPERO CRD42020173501.

Lay summary

Regardless of aetiology, patients with liver diseases have impaired quality of life. This is associated with disease progression, the presence of symptoms, treatment response, and mental, physical, and social factors such as anxiety, confusion, comorbidities, and fatigue, as well as limitations in daily living, including loneliness, low income, stigmatisation, and treatment costs. Patients highlighted the need for information to understand and manage liver disease, and awareness and support from healthcare professionals to better cope with the disease. In addition, there is a need to raise awareness of liver diseases in the general population to reduce negative preconceptions and stigmatisation.

•

Patients with liver disease regardless of aetiology and severity have impaired quality of life.

•

Patients call for better education and information to understand and manage their liver disease, and for increased awareness and support from healthcare professionals.

•

Owing to the limited knowledge of liver diseases among the general population, patients experience stigmatisation, resulting in loneliness and social isolation.

•

Addressing unmet needs of patients with liver disease could improve their quality of life.

Mobile app requirements for patients with rare liver diseases: A single center survey for the ERN RARE-LIVER‬‬‬

BACKGROUND

More patient data are needed to improve research on rare liver diseases. Mobile health apps enable an exhaustive data collection. Therefore, the European Reference Network on Hepatological diseases (ERN RARE-LIVER) intends to implement an app for patients with rare liver diseases communicating with a patient registry, but little is known about which features patients and their healthcare providers regard as being useful.

AIMS

This study aimed to investigate how an app for rare liver diseases would be accepted, and to find out which features are considered useful.

METHODS

An anonymous survey was conducted on adult patients with rare liver diseases at a single academic, tertiary care outpatient-service. Additionally, medical experts of the ERN working group on autoimmune hepatitis were invited to participate in an online survey.

RESULTS

In total, the responses from 100 patients with autoimmune (n = 90) or other rare (n = 10) liver diseases and 32 experts were analyzed. Patients were convinced to use a disease specific app (80%) and expected some benefit to their health (78%) but responses differed significantly between younger and older patients (93% vs. 62%, p < 0.001; 88% vs. 64%, p < 0.01). Comparing patients' and experts' feedback, patients more often expected a simplified healthcare pathway (e.g. 89% vs. 59% (p < 0.001) wanted access to one's own medical records), while healthcare providers saw the benefit mainly in improving compliance and treatment outcome (e.g. 93% vs. 31% (p < 0.001) and 70% vs. 21% (p < 0.001) expected the app to reduce mistakes in taking medication and improve quality of life, respectively).

CONCLUSION

Our results underline the great desire for disease-specific apps but also the need to involve patients and healthcare providers in the development of such apps in order to achieve long-term use and, thereby, improvements of patient care and research. The results of this study will help tremendously to implement the first cross-country app that communicates with an ERN patient registry.

Drug withdrawal in patients with autoimmune hepatitis in long-term histological remission: A prospective observational study

BACKGROUND

Recommendations for drug withdrawal in patients with autoimmune hepatitis (AIH) in longstanding remission are conflicting and rely on retrospective data. We prospectively investigated the predictive value of histological normalisation for successful treatment withdrawal in AIH patients.

METHODS

Non-cirrhotic patients with established AIH and complete biochemical remission (normalisation of serum alanine aminotransferase [ALT] or aspartate aminotransferase [AST] and immunoglobulin G [IgG]) of at least 2 years were biopsied. Immunosuppressive therapy was only withdrawn in patients with histological normalisation (histological activity index [HAI] ≤3) with a minimum follow-up of 12 months.

RESULTS

A total of 17 patients in biochemical remission for at least 2 years were included. Persistent histological inflammatory activity (HAI >3) precluded drug withdrawal in five patients. These had higher values of ALT (25 vs. 16 U/L; p = 0.01) and AST (26 vs. 22 U/L; p = 0.01) compared with patients in histological remission. Immunosuppressive medication was withdrawn in 12 patients; eight (67%, C.I. 40-93% p = 0.4) remained in remission during a median follow-up of 62 months (range: 13-75 months); and four (33%, C.I. 7-60% p = 0.4) required reinstitution of therapy after 1, 6, 11, and 40 months, all without clinical signs of disease progression or hepatic decompensation. No predictors of relapse were identified.

CONCLUSION

Two-thirds of the patients who prove to have histological normalisation after at least 2 years of biochemical remission achieve treatment-free remission. Although patient numbers were small and results should be interpreted with caution, these findings support a liver biopsy prior to drug withdrawal.

An update on the pharmacological management of autoimmune hepatitis

Introduction: Autoimmune hepatitis (AIH) is an immune mediated, inflammatory disease affecting the liver as a result of environmental triggers in susceptible individuals leading to loss of self-tolerance. The immunopathogenesis of AIH is not fully understood, which limits targeted therapeutic options.Areas covered: In this review, the authors provide an overview of current practice in the management of AIH, which include induction therapy with corticosteroids (± thiopurines), followed by maintenance therapy. Lack of early response to treatment may serve as a predictor of those at risk of requiring treatment escalation to second- and third-line agents such as mycophenolate mofetil (MMF), calcineurin inhibitors or biologics. Evidence for third-line agents from small retrospective studies or individual centers are reviewed. The nuances of AIH treatment in pregnancy, overlap syndromes, and drug induced liver injury (DILI) warrant further consideration.Expert opinion: Augmenting the balance of regulatory T cells (Treg) and effector T cells is an appealing therapeutic target with a multitude of agents in development. Many of the challenges in AIH research are due to its rarity and lack of randomized data. Management of AIH should strive towards individualized care through risk stratification and use of the best therapeutic modality for each patient.

Health-related quality of life in patients with autoimmune hepatitis

BACKGROUND

Autoimmune hepatitis (AIH) is a rare chronic liver disease. Impaired health-related quality of life (HRQL) contributes to the overall disease burden. At current, only limited data related to the impact of treatment response on HRQL are available.

OBJECTIVE

The aim of the study was to determine the impact of biochemical remission on HRQL.

METHODS

Patients with AIH were prospectively enrolled between July 2018 and June 2019. A liver disease-specific tool, the chronic liver disease questionnaire (CLDQ) and the generic EQ-5D-5L were used to quantify HRQL. Treatment response was assessed biochemically by measurement of immunoglobulin G, ALT and AST. The cohort was divided into two groups according to their biochemical remission status in either complete vs. incomplete remission. Clinical as well as laboratory parameters and comorbidities were analysed using univariable and multivariable analysis to identify predictors of poor HRQL.

RESULTS

A total of 116 AIH patients were included (median age: 55; 77.6% female), of which 9.5% had liver cirrhosis. In this cohort, 38 (38.4%) showed a complete and 61 (61.6%) an incomplete biochemical remission at study entry. The HRQL was significantly higher in patients with a complete as compared to an incomplete biochemical remission (CLDQ overall score: 5.66 ± 1.15 vs. 5.10 ± 1.35; p = 0.03). In contrast, the generic EQ-5D-5L UI-value was not different between the groups. Multivariable analysis identified AST (p = 0.02) and an incomplete biochemical remission (p = 0.04) as independent predictors of reduced HRQL (CLDQ total value).

CONCLUSION

Patients with a complete biochemical remission had a significantly higher HRQL. Liver-related quality of life in patients living with AIH is dependent on the response to immunosuppressive treatment.

Recent updates on the management of autoimmune hepatitis

Autoimmune hepatitis (AIH) is an immunoinflammatory chronic liver disease with dynamic and rather heterogeneous disease manifestations. A trend of increasing prevalence of AIH has been observed worldwide, along with a relative increase in the percentage of male patients. AIH is characterized and diagnosed based on serum biochemistry and liver histology: elevated aminotransferases and serum immunoglobulin G (IgG), the presence of serum anti-nuclear antibody or anti-smooth muscle antibody, and interface lympho-plasmacytic hepatitis. Clinical manifestations differ among disease subtypes with distinct time-frames, i.e., AIH with a chronic insidious onset, and acute-onset AIH (the diagnosis of which is often challenging due to the lack of typical serum findings). The absence of disease-specific biomarkers or histological findings may expand the disease phenotype into drug-induced AIH-like liver injury. Corticosteroids and azathioprine are recommended first-line treatments for AIH. The complete normalization of aminotransferases and serum IgG is an essential treatment response to ensure long-term overall survival. An incomplete response or intolerance to these drugs is considered an indication for second-line treatment, especially with mycophenolate mofetil. Life-long maintenance treatment is required for the majority of patients, but the few who achieve prolonged and stringent biochemical remission with lower alanine aminotransferase and IgG within the normal range may be able to discontinue the medications. In the future, the quality of life of AIH patients should be managed by personalized medicine, including the appropriate selection and dosing of first-line therapy and perhaps alternating with potential therapeutics, and the prediction of the success of treatment withdrawal.

Quality of life among patients with autoimmune hepatitis in remission: A comparative study

Health-related quality of life (HRQOL) is lower in individuals with autoimmune hepatitis (AIH) than in the general population. However, previous evaluations of HRQOL for AIH have included a broad range of disease activities. The aim of this study was to clarify HRQOL among patients with AIH in remission.We assessed HRQOL in patients with AIH in remission, patients with chronic hepatitis C (CHC) with eradicated hepatitis C virus (HCV) and patients with primary biliary cholangitis (PBC) using the Japanese version of the Chronic Liver Disease Questionnaire (CLDQ).Participants comprised 62 patients with AIH in remission, 39 patients with CHC with eradicated HCV and 66 patients with PBC. Median ages of patients were 63, 69, and 64 years, respectively. Overall score (5.6 vs 5.9, P = .02) and fatigue (5.2 vs 5.6, P = .01) and worry (5.6 vs 6.0, P = .01) domain scores of the CLDQ were significantly lower in patients with AIH in remission than in CHC with eradicated HCV, and similar to scores except for the systemic symptoms domain in patients with PBC. Disease duration was associated with lower scores on systemic symptoms and activity domains of the CLDQ in patients with AIH in remission.Patients with AIH in remission show impaired HRQOL associated with disease duration.

Vitamin-D Receptor-Gene Polymorphisms Affect Quality of Life in Patients with Autoimmune Liver Diseases

Vitamin D deficiency has been associated with depressive symptoms and reduced physical functioning. The aim of the study was to characterize the relationship between polymorphisms of the vitamin D receptor (VDR) gene and the quality of life in patients with autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC). Three polymorphisms of the VDR gene (TaqI-rs731236, BsmI-rs1544410, and ApaI-rs7975232) were analyzed in patients with AIH (n = 142) and PBC (n = 230) and in healthy individuals (n = 376). Patient quality of life was assessed by validated questionnaires such as Medical Outcomes Study Short-Form 36 (SF-36), State Trait Anxiety Inventory (STAI), Modified Fatigue-Impact Scale (MFIS), Patient-Health Questionnaire 9 (PHQ-9), and PBC-40. The TaqI C and ApaI A alleles are risk alleles in both AIH and PBC, and a significant dominance of the A allele in BsmI was observed in AIH patients. In terms of quality of life, the presence of the CC or CT TaqI genotype was associated with emotional reactions, including the fatigue and the cognitive skills of patients with PBC, whereas in the group of AIH patients, homozygotes CC of TaqI, AA of BsmI, and AA of ApaI had worse physical, social, emotional, and mental function. The genetic variations of VDR gene can influence individual susceptibility to develop chronic autoimmune liver diseases such as AIH and PBC and affect quality of life.

Autoimmune Hepatitis: 2019 Update

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease, characterized by the elevation of aminotransferases, presence of anti-nuclear antibody or anti-smooth muscle antibody, elevated immunoglobulin G (IgG), and interface hepatitis/plasma-lymphocytic inflammation based on histology. Recent epidemiological studies have indicated an increasing trend in the prevalence of AIH worldwide, especially in male patients; this trend may suggest the alteration of environmental triggers of disease onset over time. As no disease-specific biomarker or histological finding is currently available, AIH requires a clinical diagnosis, and a validated diagnostic scoring system with acceptable specificity and sensitivity has been proposed. Regarding treatment, corticosteroids and azathioprine are recommended, and in those who exhibit an incomplete response or those who are intolerant to these drugs, second-line therapy, such as mycophenolate mofetil, is considered. Overall, the long-term outcome is excellent in patients with complete biochemical responses, while life-long maintenance treatment may be required since the cessation of immunosuppressive agents frequently leads to the relapse of the disease. Acute-onset AIH does occur, and the diagnosis is very challenging due to the lack of serum autoantibodies or elevated IgG. The unmet needs include earlier diagnosis, intervention with disseminated clinical practice guidelines, and recognition and improvement of patients’ health-related quality of life with the development of novel corticosteroid-free treatment regimens.

Cannabidiol (CBD) Consumption and Perceived Impact on Extrahepatic Symptoms in Patients with Autoimmune Hepatitis

BACKGROUND AND AIMS

Utilization and safety of cannabidiol (CBD) in patients with autoimmune hepatitis (AIH) are currently unknown. We aimed to identify the frequency of CBD use, impact on symptoms, and safety profile.

METHODS

An invitation to complete a CBD-specific questionnaire was posted every other day to well-established autoimmune hepatitis Facebook communities (combined membership of 2600 individuals) during a 10-day study period. Age ≥ 18 years and an AIH diagnosis by a physician were the eligibility criteria for participation in the survey.

RESULTS

In total, 371 AIH patients (median age 49 years, 32% reported advanced fibrosis) completed the questionnaire. Respondents were 91% women, 89% Caucasian, and 89% from North America. Ninety-three (25%) respondents were ever CBD users, with 55 of them (15% of the survey responders) identified as current users. Among ever users, 45.7% reported their treating doctors were aware of their CBD use. The most common reason cited for CBD use was pain (68%), poor sleep (62%), and fatigue (38%). Most respondents using CBD for these symptoms reported a significant improvement in pain (82%), sleep (87%), and fatigue (61%). In ever CBD users, 17.3% were able to stop a prescription medication because of CBD use: pain medication (47%), immunosuppression (24%), and sleep aids (12%). Side effects attributed to CBD use were reported in 3% of CBD users, yet there were no reported emergency department visits or hospitalizations.

CONCLUSION

CBD use was not uncommon in patients with AIH, and its use was associated with reports of improvement in extrahepatic symptoms.

Clinical management of autoimmune hepatitis

Autoimmune hepatitis is a rare and chronic liver disease that is characterised by increased serum transaminases and immunoglobulin G, inflammatory liver histology and presence of circulating autoantibodies. An autoimmune hepatitis diagnosis justifies life-long treatment in most patients in order to prevent development of cirrhosis and end-stage liver disease. The cornerstone of treatment is steroid induction therapy followed by maintenance therapy with azathioprine, which is effective in most cases. For patients who do not respond to standard treatment, second-line treatment with other immunosuppressants can be effective. Treatment should be aimed at biochemical remission of the disease, which is defined as normalization of transaminases and immunoglobulin G. Patients should be monitored intensively during the first months of treatment in order to monitor side-effects, assess symptoms and individualise treatment. Specialist consultation should be sought in difficult-to-treat patients. Future studies and networking initiatives should result in optimization of current treatment strategies in autoimmune hepatitis.

Challenges in the use of corticosteroids in the management of autoimmune hepatitis

Autoimmune hepatitis is widely assumed by health-care professionals to be a disease that is easily controlled through the use of corticosteroids and immunosuppressants but recent studies in the UK indicate highly variable treatment regimens and often unsatisfactory treatment outcomes, such as dependence on long-term high-dose steroids and ongoing need for liver transplantation in some cases. The therapeutic use of the systemically acting corticosteroid prednisolone results in unacceptable side effects in many patients. Recent evidence suggests that it is not always necessary to use high-dose steroids (>0.5 mg/kg/d) to attain remission; and side effects may also be minimised through more targeted therapy with the less systemically-absorbed corticosteroid, budesonide. The authors offer advice on the stratification of treatment for these patients and suggest changes to improve the services available for people with autoimmune hepatitis in the UK.
