Tacrolimus versus mycophenolate for AutoImmune hepatitis patients with incompLete response On first-line therapy (TAILOR study): a study protocol for a phase III, open-label, multicentre, randomised controlled trial

Background: Autoimmune hepatitis (AIH) is a rare, chronic inflammatory disease of the liver. The treatment goal is reaching complete biochemical response (CR), defined as the normalisation of aspartate and alanine aminotransferases and immunoglobulin gamma. Ongoing AIH activity can lead to fibrosis and (decompensated) cirrhosis. Incomplete biochemical response is the most important risk factor for liver transplantation or liver-related mortality. First-line treatment consists of a combination of azathioprine and prednisolone. If CR is not reached, tacrolimus (TAC) or mycophenolate mofetil (MMF) can be used as second-line therapy. Both products are registered for the prevention of graft rejection in solid organ transplant recipients. The aim of this study is to compare the effectiveness and safety of TAC and MMF as second-line treatment for AIH. Methods: The TAILOR study is a phase IIIB, multicentre, open-label, parallel-group, randomised (1:1) controlled trial performed in large teaching and university hospitals in the Netherlands. We will enrol 86 patients with AIH who have not reached CR after at least 6 months of treatment with first-line therapy. Patients are randomised to TAC (0.07 mg/kg/day initially and adjusted by trough levels) or MMF (max 2000 mg/day), stratified by the presence of cirrhosis at inclusion. The primary endpoint is the difference in the proportion of patients reaching CR after 12 months. Secondary endpoints include the difference in the proportion of patients reaching CR after 6 months, adverse effects, difference in fibrogenesis, quality of life and cost-effectiveness. Discussion: This is the first randomised controlled trial comparing two second-line therapies for AIH. Currently, second-line treatment is based on retrospective cohort studies. The rarity of AIH is the main issue in clinical research for alternative treatment options. The results of this trial can be implemented in existing international clinical guidelines.

The long-term impact of autoimmune pancreatitis on pancreatic function, quality of life, and life expectancy

Objective: To evaluate the long-termoutcome of autoimmune pancreatitis. Methods: Patients with at least 2 years of follow-up were included. Information was collected regarding disease characteristics, treatment outcome, diagnosedmalignancies, andmortality. In addition, pancreatic function and quality of life were assessed prospectively. Results: 107 patients were included (87% men, 90% with type 1), with a median follow-up of 74 (interquartile range, 49-108) months. One third was operated for suspected pancreatic cancer (32%). Most patients were (successfully) treated with steroids (83%), but relapses were common (52%), for which no risk factors could be identified. Pancreatic carcinoma was not observed. Prospective data were obtained from 64%, as 17% had died, 7% were lost to follow-up, and 13% refused to participate. After a median of 75 (interquartile range, 50-106) months, 46% still used active treatment. Exocrine and endocrine insufficiencieswere highly prevalent (82%and 57%, respectively). Quality of life and survival were not impaired, as compared with a reference population. Conclusions: Despite an excellent initial treatment response, relapses are common, even in type 2, and almost half of the patients require maintenance therapy. Pancreatic insufficiency is highly prevalent, which calls for active screening. Pancreatic cancer was not observed, and quality of life and survival are not impaired

Comparable efficacy of low- versus high-dose induction corticosteroid treatment in autoimmune pancreatitis

OBJECTIVE: The objective of this study was to compare efficacy of high versus low doses of prednisone for induction of remission in autoimmune pancreatitis (AIP). METHODS: This is a retrospective, multicenter study including patients diagnosed with AIP between May 1992 and August 2011. Clinical, laboratory and imaging findings were assessed before treatment and at 1, 3, and 6 months after starting treatment. RESULTS: A total of 65 patients (57 males; median age, 63 years) were treated with an initial low dose (10-20 mg/d, n = 14), a medium dose (30 mg/d, n = 15), or a high dose (40-60 mg/d, n = 36) of prednisone. There were no significant differences in baseline characteristics between the treatment groups including age, presenting symptoms and laboratory results. During a follow-up period of 6 months, in nearly all patients, symptoms (jaundice, weight loss) resolved completely. After 6 months, treatment response with respect to symptomatic, radiological, and laboratory improvement was comparable for the different dosage groups. CONCLUSIONS: Response to therapy was comparable for AIP patients treated with doses of prednisone in the range of 10 to 60 mg/d. A prospective trial should be conducted to confirm efficacy of lower-dose prednisone treatment

Health-related quality of life in patients with primary sclerosing cholangitis: A longitudinal population-based cohort study

Background & Aims: Data regarding health-related quality of life (HRQoL) in primary sclerosing cholangitis (PSC) are sparse and have only been studied cross-sectionally in a disease which runs a fluctuating and unpredictable course. We aim to describe HRQoL longitudinally by using repeated measurements in a population-based cohort. Methods: Every 3 months from May 2017 up to August 2020, patients received digital questionnaires at home. These included the EQ-5D, 5-D Itch, patient-based SCCAI and patient-based HBI. The SF-36, measuring HRQoL over eight dimensions as well as a physical component summary (PCS) and mental component summary (MCS) score, was sent annually. Data were compared with Dutch reference data and a matched IBD disease control from the population-based POBASIC cohort. Mixed-effects modelling was performed to identify factors associated with HRQoL. Results: Three hundred twenty-eight patients completed 2576 questionnaires. A significant reduction of small clinical relevance in several mean HRQoL scores was found compared with the Dutch reference population: 46.4 versus 48.0, p =.018 for PCS and 47.5 versus 50.5, p =.004 for MCS scores. HRQoL outcomes were significantly negatively associated with coexisting active IBD (PCS −12.2, p <.001 and MCS −12.0, p <.001), which was not the case in case of quiescent IBD. Decreasing HRQoL scores were also negatively associated with increasing age (PCS −0.1 per 10 years, p =.002), female sex (PCS -2.8, p <.001), diagnosis of AIH overlap (PCS -3.7, p =.059), end-stage liver disease (PCS -3.7, p =.015) and presence of itch (PCS -9.2, p <.001 and MCS −3.1, p =.078). The odds of reporting a clinically relevant reduction in EQ-5D scores showed seasonal variation, being lowest in summer (OR = 0.48 relative to spring, p =.037). In patients with liver transplant, HRQoL outcomes were comparable to the Dutch general population. Conclusions: PSC patients report impaired HRQoL of small clinical relevance compared with the general population. After liver transplantation, HRQoL scores are at comparable levels to the general population. HRQoL scores are associated with potentially modifiable factors such as itch and IBD activity

Assessing the efficacy and safety of mycophenolate mofetil versus azathioprine in patients with autoimmune hepatitis (CAMARO trial): study protocol for a randomised controlled trial.

BACKGROUND: Currently, the standard therapy for autoimmune hepatitis (AIH) consists of a combination of prednisolone and azathioprine. However, 15% of patients are intolerant to azathioprine which necessitates cessation of azathioprine or changes in therapy. In addition, not all patients achieve complete biochemical response (CR). Uncontrolled data indicate that mycophenolate mofetil (MMF) can induce CR in a majority of patients. Better understanding of first-line treatment and robust evidence from randomised clinical trials are needed. The aim of this study was to explore the potential benefits of MMF as compared to azathioprine, both combined with prednisolone, as induction therapy in a randomised controlled trial in patients with treatment-naive AIH. METHODS: CAMARO is a randomised (1:1), open-label, parallel-group, multicentre superiority trial. All patients with AIH are screened for eligibility. Seventy adult patients with AIH from fourteen centres in the Netherlands and Belgium will be randomised to receive MMF or azathioprine. Both treatment arms will start with prednisolone as induction therapy. The primary outcome is biochemical remission, defined as serum levels of alanine aminotransferase and immunoglobulin G below the upper limit of normal. Secondary outcomes include safety and tolerability of MMF and azathioprine, time to remission, changes in Model For End-Stage Liver Disease (MELD)-score, adverse events, and aspects of quality of life. The study period will last for 24 weeks. DISCUSSION: The CAMARO trial investigates whether treatment with MMF and prednisolone increases the proportion of patients in remission compared with azathioprine and prednisolone as the current standard treatment strategy. In addition, we reflect on the challenges of conducting a randomized trial in rare diseases. TRIAL REGISTRATION: EudraCT 2016-001038-91 . Prospectively registered on 18 April 2016
