Anti-IgLON5 disease is a newly defined clinical entity characterized by progressive course with high disability and mortality rate. While precise pathogenetic mechanisms remain unclear, features characteristic of both autoimmune neurodegenerative diseases were reported. Data on immunotherapy are limited, its efficacy remains controversial. In this study, we retrospectively investigated an anti-IgLON5 cohort special focus clinical, serological genetic predictors the response long-term...

Abstract Autoantibodies against contactin-associated protein 2 (Caspr2) not only induce limbic autoimmune encephalitis but are also associated with pain conditions. Here, we analyzed clinical data on in a large cohort of patients included into the German Network for Research Autoimmune Encephalitis. Out 102 our cohort, was frequent symptom (36% all patients), often severe (63.6% pain) and/or even major (55.6% pain). Pain phenotypes differed between patients. Cluster analysis revealed two...

Abstract Background and objectives Corticosteroids or plasma exchange are recommended for acute treatment of autoimmune encephalitis (AE). Intravenous immunoglobulins (IVIG) suggested as an additional option but data on effect is scarce. The objective the present study was to investigate impact first-line three most common forms AE, in particular, evaluate IVIG therapy these diseases. Methods A total 1274 patients from German Network Autoimmune Encephalitis Research (GENERATE) were analyzed,...

OBJECTIVES: Diagnosis of covert hepatic encephalopathy (CHE) is challenging and often neglected in clinical practice. The aim this study was to develop an easy-to-perform score predict CHE patients with cirrhosis. METHODS: For the development or validation cohort proposed score, 142 96 consecutive cirrhosis were prospectively enrolled. Psychometric Hepatic Encephalopathy Score used detect minimal encephalopathy. All examined simplified animal naming test asked complete Chronic Liver Disease...

Patients with liver cirrhosis often suffer from complications such as ascites, gastrointestinal bleeding, and infections, resulting in impaired quality of life. Frequently, the close relatives patients also a lower life chronic diseases. In recent years, acute-to-chronic failure has been defined separate entity high mortality. Often several organs are affected which makes intensive care therapy necessary. Little is known about influence acute-on-chronic-liver (ACLF) on psychosocial burden...

Background: Current EASL/AASLD guidelines recommend treatment of covert hepatic encephalopathy (HE) only in symptomatic patients, for example, those with impaired quality life or affected driving abilities. Goals: Because testing is time consuming, the aim present study was to identify simple clinical predictors poor patients HE (CHE).

Cholestatic liver injury results from impaired bile flow or metabolism and promotes hepatic inflammation fibrogenesis. Toxic acids that accumulate in cholestasis induce apoptosis contribute to early cholestatic injury, which is amplified by accompanying inflammation. The aim of the current study was evaluate role antiapoptotic caspase 8-homolog cellular FLICE-inhibitory (cFLIP) protein during acute injury. Transgenic mice exhibiting hepatocyte-specific deletion cFLIP (cFLIP −/− ) were used...
