AIM: To evaluate the therapeutic effects of ursodeoxycholic acid (UDCA) on autoimmune hepatitis (AIH). METHODS: A total 136 patients who were diagnosed with AIH were included in our study. All of the patients underwent a liver biopsy, and had at least a probable diagnosis on the basis of either the revised scoring system or the simplified scores. Initial treatment included UDCA monotherapy (Group U, n = 48) and prednisolone (PSL) monotherapy (Group P, n = 88). Group U was further classified into two subgroups according to the effect of UDCA: Patients who had achieved remission induction with UDCA monotherapy and showed no sign of relapse (Subgroup U1, n = 34) and patients who additionally received PSL during follow-up (Subgroup U2, n = 14)...

Although autoimmune hepatitis (AIH) is frequently complicated with chronic thyroiditis or other autoimmune disorders, reports on its association with immune thrombocytopenic purpura (ITP) are scarce. We herein describe a case of AIH associated with ITP. A 75-year-old Japanese woman was admitted to our hospital due to increased aminotransferase levels and severe thrombocytopenia. Elevated serum immunoglobulin G (IgG) was detected, and tests for platelet-associated IgG and anti-nuclear antibody were positive...

OBJECTIVES: Autoimmune hepatitis (AIH) is a relatively rare cause of hepatic dysfunction, which can lead to acute liver failure (ALV) and cirrhosis if not treated. The performance of transient elastography (TE) compared to liver biopsy has been evaluated in many liver diseases. The aim of the present study was to evaluate the performance of TE and other non-invasive markers for liver fiibrosis in patients with biopsy-proven AIH. METHODS: Fifty-three patients who were treated at the department of gastroenterology and hepatology of the University Clinic Essen from 2008 to 2013 included in this retrospective study...

 Acute hepatitis E is becoming increasingly recognised in Europe with up to 40% of the population in Southern France being exposed to the virus, which is harboured in pigs. Patients with known liver disease may present with acute hepatitis E and present a diagnostic challenge. For example patients with autoimmune hepatitis (AIH) who are immunosuppressed and contract hepatitis E may be at increased risk of developing chronicity due to concurrent immunosuppression. Importantly, the diagnosis may be missed with the infection misdiagnosed as an autoimmune flare, and immunosuppression increased by the attending physician, thus enhancing the risk of chronicity of infection leading to progressive liver injury in immunocompromised patients...

In this paper, a poly ligand exchanger, Cu(II)-loaded chelating resin bearing the functional group of weak iminodiacetate acid was prepared to efficiently remove ammonia from solutions. Batch adsorption equilibrium experiments were conducted under a range of conditions to determine the optimum adsorption conditions. The effects of contact time, pH, resin dosage and temperature on the removal of ammonia by a Cu(II)-loaded resin were determined. The maximum removal efficiency was reached at pH 9.5 at room temperature, 25°C, in 300 min...

Autoimmune hepatitis (AIH) is an uncommon, chronic inflammatory, and relapsing liver disease of unknown origin that may lead to liver cirrhosis, hepatocellular carcinoma, liver transplantation, or death. AIH occurs in all age groups and races but can frequently manifest as acute fulminant hepatitis. Clinical presentation of AIH can have features similar to primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC), and these diseases may coexist leading to overlap syndromes. Although histological diagnosis is necessary, imaging features often can demonstrate characteristics that may be helpful to distinguish these diseases...

A 32-year-old immigrant man presented with new onset jaundice. His past medical history was significant for type 2 diabetes mellitus, hypertension, and hyperlipidemia. His initial laboratory finding and liver biopsy were suggestive of autoimmune hepatitis (AIH). The plan was to start steroids pending negative results for viral serology, but it came back positive for hepatitis E virus. The patient's liver function test and clinical condition improved significantly on conservative management over a period of 1 month...

Autoimmune hepatitis (AIH) is an uncommon chronic autoimmune liver disease. Several studies reported the association of polymorphisms between CD28, CTLA4 and ICOS gene cluster in 2q33.2 with autoimmune or inflammatory diseases. The previous genome-wide association study on type 1 AIH in a European population has reported a risk G allele of a single nucleotide polymorphism (SNP), rs4325730, in this region. Here, we conducted an association study of this SNP with type 1 AIH in a Japanese population, as a replication study...

: Autoimmune hepatitis (AIH) is defined as a chronic liver inflammation with loss of tolerance against hepatocytes. The etiology and pathophysiology of AIH are still poorly understood because reliable animal models are limited. Therefore, we recently introduced a model of experimental murine AIH by a self-limited adenoviral infection with the AIH type 2 antigen formiminotransferase cyclodeaminase (FTCD). We could demonstrate that break of humoral tolerance towards liver specific autoantigens like FTCD and cytochrome P450 2D6 (CYP2D6) is not dependent on the genetic background...

Although it is well known that chronic hypoxia induces muscle wasting, the effects of intermit-tent hypoxia on skeletal muscle protein metabolism remains unclear. We hypothesized that acute intermittent hypoxia (AIH), a challenge that activates the hypothalamic-pituitary-adrenal axis, would alter muscle protein homeostasis through a glucocorticoid-dependent mechanism. Three-week-old rats were submitted to adrenalectomy (ADX) and exposed to 8 h of AIH (6% O2 for 40s at 9 min intervals). Animals were sacrificed and the soleus and extensor digitorum longus (EDL) muscles were harvested and incubated in vitro for measurements of protein turn-over...

Phrenic motor facilitation (pMF) can be elicited by acute intermittent hypoxia (ie. phrenic long-term facilitation, or pLTF), or direct application of pharmacological agonists to the cervical spinal cord. Moderate acute intermittent hypoxia (mAIH, 3X5 min episodes of 35-50 mmHg arterial PO2, 5 min normoxic intervals) induces pLTF by a serotonin-dependent mechanism; mAIH-induced pLTF is abolished by even low levels of systemic inflammation induced by lipopolysaccharide (LPS, 100ug/kg i.p.). In contrast, severe AIH (sAIH, 3X5 min episodes of 25-30mmHg arterial PO2, 5 min intervals) elicits pLTF by a distinct, adenosine-dependent mechanism...

BACKGROUND: Prednisone plus azathioprine is considered the mainstay of therapy in the current recommendations for autoimmune hepatitis (AIH). However, it does not provide good benefits for AIH patients because of its serious side effects. Therefore, more and more AIH patients prefer to seek for traditional Chinese medicine (TCM) to manage their symptoms and reduce the side effects of steroids in China. Shu-Gan-Jian-Pi Decoction is a popular used Chinese herbal formula in Guangdong province of China, which has demonstrated the effect of improving efficacy and reducing side effects of corticosteroids in AIH patients...

REVIEW
Urs Christen, Edith Hintermann
Autoimmune hepatitis (AIH) is characterized by a progressive destruction of the liver parenchyma and a chronic fibrosis. The current treatment of autoimmune hepatitis is still largely dependent on the administration of corticosteroids and cytostatic drugs. For a long time the development of novel therapeutic strategies has been hampered by a lack of understanding the basic immunopathogenic mechanisms of AIH and the absence of valid animal models. However, in the past decade, knowledge from clinical observations in AIH patients and the development of innovative animal models have led to a situation where critical factors driving the disease have been identified and alternative treatments are being evaluated...
