BACKGROUND AND AIMS: Ten percent to 20% of children with autoimmune hepatitis (AIH) require second-line therapy to achieve remission. Although current guidelines exist on first-line management, evidence for second-line therapy in treatment-refractory patients is lacking. Our aim was to perform a systematic review and meta-analysis of the efficacy and safety of second-line treatments used in this population. METHODS: Electronic and manual searches were used to identify potential studies for inclusion...

BACKGROUND: Ten to forty percent of nonalcoholic steatohepatitis (NASH) and HCV-related chronic liver disease (CLD-C) patients have antinuclear antibodies (ANAs). However, the relationship between autoimmune response and insulin resistance remains uncertain among those patients. The primary purpose of this study was to investigate whether or not ANA status was associated with the development of insulin resistance and obesity in NASH and CLD-C patients. METHODS: Degrees of hepatic fibrosis and steatosis were evaluated by the classification proposed by Brunt et al...

Persistent hepatitis C virus (HCV) infection may induce autoimmune diseases and chronic hepatitis C is sometimes accompanied by autoimmune hepatitis (AIH). However, we are worried about the treatment for chronic hepatitis C-AIH overlap syndrome because interferon-based antiviral therapies may enhance autoimmunity and immunosuppressive corticosteroid administration may promote viral replication. Here, we report a patient having chronic hepatitis C-AIH overlap syndrome treated with the direct-acting antivirals (DAA), daclatasvir and asunaprevir...

REVIEW
T Visseren, S Darwish Murad
Liver transplantation is a well-accepted treatment for decompensated chronic liver disease due to primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC) and auto-immune hepatitis (AIH). Survival after liver transplantation is generally good with 1 and 5-year survival rates around 90% and 70-85%. After transplantation, however, these diseases recur in 8.6-27% (rPSC), 10.9-42.3% (rPBC) and 7-42% (rAIH), and this poses significant challenges in terms of management and graft outcome in these patients...

BACKGROUND: Predniso(lo)ne, alone or in combination with azathioprine, is the standard of care (SOC) therapy for autoimmune hepatitis (AIH). However, the SOC therapy is poorly tolerated or does not control disease activity in up to 20% of patients. We assessed the efficacy of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy for patients with AIH. PATIENTS AND METHODS: We performed a retrospective study of data (from 19 centres in Europe, the United States, Canada, and China) from 201 patients with AIH who received second-line therapy (121 received MMF and 80 received tacrolimus), for a median of 62 months (range, 6-190 months)...

Imbalance between T regulatory (Treg) and T effector (Teff) cells is likely to contribute to induction and perpetuation of liver damage in autoimmune hepatitis (AIH) and autoimmune sclerosing cholangitis (AISC) either through inability of Tregs to restrain proliferation and effector cytokine production by responders or through conversion of Tregs into T helper type 1 (Th1) or type 17 (Th17) effector lymphocytes. We investigated the effect of Treg skewing on the phenotypic and functional properties of CD4(+) CD127(+) CD25(high) cells, an activated subset of Teff, in 32 patients with AIH, 20 with AISC and in 36 healthy subjects (HS)...

BACKGROUND & AIM: NKT cells are CD1d-restricted innate-like T cells that modulate innate and adaptive immune responses. Unlike the well-characterized invariant/type I NKT cells, type II NKT cells with a diverse TCR repertoire are poorly understood. This study defines the pathogenic role of type II NKT cells in the etiology of chronic liver inflammation. METHODS: Transgenic mice with the Lck promoter directing CD1d overexpression on T cells in Jα18 wild-type (Lck-CD1dTgJα18(+); type I NKT cell sufficient) and Jα18-deficient (Lck-CD1dTgJα18(o), type I NKT cell deficient) mice were analyzed for liver pathology and crosstalk between type II NKT cells and conventional T cells...

OBJECTIVE: Autoimmune hepatitis (AIH) is a liver disorder that affects both children and adults. It is characterized by inflammatory liver histology, elevated transaminase level, circulating nonorgan-specific autoantibodies, and increased level of immunoglobulin G in the absence of known etiology. Ventricular repolarization has been evaluated using T wave and QT interval measurements in patients with hepatic cirrhosis. Ventricular repolarization may be defined using QT interval, QT dispersion, and T wave measurements...

Autoimmune hepatitis (AIH) is a chronic hepatitis with an increasing incidence. The majority of patients require life-long immunosuppression and incomplete treatment response is associated with a disease progression. An abnormal iron homeostasis or hyperferritinemia is associated with worse outcome in other chronic liver diseases and after liver transplantation. We assessed the capacity of baseline parameters including the iron status to predict the treatment response upon standard therapy in 109 patients with untreated AIH type 1 (AIH-1) in a retrospective single center study...

Gonadal steroids modulate CNS plasticity, including phrenic long-term facilitation (pLTF), a form of spinal respiratory neuroplasticity resulting in increased phrenic nerve motor output following exposure to acute intermittent hypoxia (aIH; three 5 min episodes, 10.5% O2). Despite the importance of respiratory system neuroplasticity, and its dependence on estrogen in males, little is known about pLTF expression or mechanisms of estrogen signaling in females. Here, we tested the hypotheses that: 1) pLTF expression in young, gonadally intact female rats would be expressed during estrous cycle stages in which 17β-estradiol (E2) is naturally high (e...

BACKGROUND AND AIM: Recent studies have demonstrated that B cells and follicular helper T (Tfh) cells, which are central regulators of humoral immune response, contribute to the development and progression of autoimmune diseases. Because Tfh cells can be divided into several subsets with distinct functional properties, this study aimed to examine the roles of different subsets of circulating Tfh cells in the immune pathogenesis of autoimmune hepatitis (AIH). METHODS: Thirty-five patients with AIH, 28 patients with primary biliary cholangitis, 24 patients with chronic hepatitis B (CHB), and 44 health controls (HC) were enrolled...

BACKGROUND: Liver transplantation (LT) is an effective treatment for patients with end-stage liver disease caused by auto-immune hepatitis (AIH). However, diagnosis of AIH can be challenging for patients with end-stage liver disease at the time of transplantation. We classified patients into "probable" or "definite" AIH groups, using the diagnostic criteria of the International Autoimmune Hepatitis Group, and compared the clinical outcomes of AIH after LT in these 2 groups. METHODS: We performed a retrospective study of 18 patients who were diagnosed with AIH and underwent LT from March 2003 to March 2015 at a single institute...

There is increased interest and recognition of the clinical variants of Sclerosing Cholangitis (SC) namely IgG4-SC, PSC/AIH overlap and PSC. For most Centers, the characteristic of IgG4-SC has not been thoroughly clinically compared with other sclerosing cholangitis variants. Further there are relatively few PSC/AIH overlap patients and the clinical outcome is not well characterized, especially for the PSC/AIH overlap syndrome. Our objective herein is to clarify the differences and similarities of the natural history of IgG4-SC, the PSC/AIH overlap and PSC alone...
