autoimmune liver diseases

Acute hepatitis can result from a wide variety of noninfectious causes that include, but are not limited to, drugs (drug-induced hepatitis), alcohol (alcoholic hepatitis), immunologic (autoimmune hepatitis, primary biliary cholangitis), or as a result of indirect insult secondary to biliary tract dysfunction (cholestatic hepatitis), pregnancy-related liver dysfunction, shock, or metastatic disease. In clinical settings, these causes are not uncommon to overlap with each other or are masked by obviously visible causes in medical history...

RATIONALE: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease characterized by excessive immune activation. It is more commonly seen in children but increasingly recognized in adults. Primary HLH relies on a genetic predisposition, whereas secondary HLH develops in the context of infections, malignancies, or autoimmune diseases. Hemophagocytic lymphohistiocytosis has been rarely described in patients on immunosuppressive therapy after kidney transplant. Here, we describe a case of HLH in a patient with a remote history of kidney transplant, triggered by a viral infection...

PURPOSE: SARS-CoV-2 infection has been associated with the impairment of several organs, including the liver. In addition, cases of autoimmune hepatitis have been described in association with COVID-19 disease. According to some case reports, vaccination has also been suggested to elicit the immune liver disorder. CASE DESCRIPTION: We report on the case series of two middle-aged women developing COVID-19 infection despite a completed vaccination schedule. More interestingly, the infection was followed by the onset of acute hepatitis with a significant increase in the values of liver function tests (x 10 normal values)...

Patients with predominantly antibody deficiencies (PADs) display hypogammaglobulinemia with a high prevalence of infections, along with autoimmune manifestations, benign and malignant lymphoproliferation and granulomatous disease. It is noteworthy that PAD patients, even those with defects in the same causative genes, display a variable clinical phenotype, suggesting that additional genetic polymorphisms, located in either immune-related or non-immune-related genes, may affect their clinical and laboratory phenotype...

INTRODUCTION: Psoriasis is a chronic inflammatory disease occurring worldwide. It is currently considered a multi-system disease, which is associated with several comorbidities. AIM: To deeply understand the clinical characteristics of psoriasis comorbidities and explore the relationship between psoriasis comorbidities, different subtypes and related influencing factors. MATERIAL AND METHODS: This retrospective study analysed data from the electronic inpatient medical record system of dermatology and non-dermatology departments at a tertiary hospital in China...

OBJECTIVE: To analyse clinical manifestations of unexplained abnormal liver function and perform hepatobiliary histopathology procedures on patients to evaluate the value of liver biopsy in diagnosing the aetiology of unexplained abnormal liver function. METHODS: A convenience sampling method was used to retrospectively collect the data of patients who were diagnosed with unexplained abnormal liver function and who received liver biopsy in the Pathology Department of Tianjin Second People's Hospital, China, between March 2022 and July 2023 to analyse liver pathology and clinical manifestations...

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that affects the joints of the human body and is projected to have a prevalence age-standardized rate of 1.5 million new cases worldwide by 2030. Several conventional and non-conventional preventive and therapeutic interventions have been suggested but they have their side effects including nausea, abdominal pain, liver damage, ulcers, heightened blood pressure, coagulation, and bleeding. Interestingly, several food-derived peptides (FDPs) from both plant and animal sources are increasingly gaining a reputation for their potential in the management or therapy of RA with little or no side effects...

Viruses can cause many human diseases. Three types of human diseases caused by viruses are discussed in this chapter: infectious diseases, autoimmune diseases, and cancers. The infectious diseases included in this chapter include three respiratory tract diseases: influenza, COVID-19, and respiratory syncytial virus. In addition, the mosquito-borne dengue virus diseases are discussed. Vitamin D can reduce risk, severity, and mortality of the respiratory tract diseases and possibly for dengue virus. Many autoimmune diseases are initiated by the body's reaction to a viral infection...

The need for retransplantation after living donor liver transplantation can occur early, mainly because of technical difficulties such as hepatic artery thrombosis or as a result of early allograft dysfunction as a symptom of small-for-size syndrome. Patients with autoimmune diseases may develop progressive graft failure from recurrent disease. The ethics of retransplantation can be complicated by the cause of the initial liver disease, which may be self-inflicted or the outcome of malignancy. This is especially true in countries without the availability of deceased donors for salvage, and a second living donor would be needed...

Autoimmune hepatitis (AIH) is a chronic, inflammatory liver disease of unknown aetiology which requires lifelong immunosuppression. Most therapeutic and outcome studies of AIH have been conducted predominantly in Caucasian (European Ancestry, EA) cohorts, with the exclusion of African American (AA) patients due to inadequate sample size. It is known that AA patients have a severe phenotype of autoimmune diseases and demonstrate a poor response to conventional medical therapy. Understanding cellular and molecular pathways which determine AIH severity and progression in AA patients is likely to lead to the discovery of novel, personalised and better tolerated therapies...

AIM OF THE STUDY: To investigate whether serum ferritin and vitamin D levels before starting autoimmune hepatitis (AIH) treatment have a role in disease prognosis regarding a therapeutic response. MATERIAL AND METHODS: The prospective study included 100 children diagnosed with AIH according to simplified criteria for diagnosis of AIH. They attended the Pediatric Hepatology Department, National Liver Institute, Menoufia University. The patients underwent measurement of liver transaminases before starting AIH treatment after 6 months from starting therapy...

INTRODUCTION: Autoimmune hepatitis (AIH) has a spectrum of symptoms ranging from asymptomatic disease to acute severe hepatitis, chronic hepatitis, and decompensated cirrhosis. The acute presentation is not rare and could represent genuine acute AIH (GAAIH) or acute exacerbation of chronic autoimmune hepatitis. We aimed to identify the prevalence, clinical features, and prognostic factors associated with GAAIH and compare these cases with acute exacerbation of chronic AIH. METHODS: This cross-sectional observational study evaluated patients with acute AIH presentation, defined as total bilirubin >5 times the upper limit of normality (xULN) and/or alanine aminotransferase >10 xULN, and no prior history of liver disease...

Celiac crisis (CC) is a rare complication of celiac disease (CD), usually observed in younger children with unrecognized CD or poor compliance with a gluten-free diet (GFD). We present a case of celiac crisis in a 3-year-old girl who was recently diagnosed with celiac disease. She was referred to our clinic with anasarca, tetany, and severe malnutrition, with hypokalemia, hypocalcemia, hypomagnesemia, and hypoalbuminemia. During hospitalization, she presented hypertransaminasemia with positive anti-actin smooth muscle antibodies (SMA)...

OBJECTIVES: Characterize the clinicopathologic features of liver biopsies from patients with celiac disease (CD). METHODS: Single center, retrospective search for liver biopsies from patients with CD. RESULTS: 36 unique patients were included, median age of 46 years (range: 2-75), including 5 pediatric patients, with an overall female predominance (25, 69 %) but in in children a male predominance was seen (p = 0.023). Most cases (75 %) had an underlying condition including autoimmune hepatitis (AIH) (11 %), AIH/primary biliary cholangitis (PBC) overlap (3 %) and PBC (3 %)...

BACKGROUND: Changes in plasma protein glycosylation are known to functionally affect proteins and to associate with liver diseases, including cirrhosis and hepatocellular carcinoma. Autoimmune hepatitis (AIH) is a liver disease characterized by liver inflammation and raised serum levels of IgG, and is difficult to distinguish from other liver diseases. The aim of this study was to examine plasma and IgG-specific N-glycosylation in AIH and compare it with healthy controls and other liver diseases...

Primary sclerosing cholangitis (PSC) is a variably progressive, fibrosis-causing autoimmune disorder of the intra- and extra-hepatic bile ducts of unclear etiology. PSC is commonly (in 60-90% of cases) associated with an inflammatory bowel disease (IBD) like PSC-IBD, and less commonly with an autoimmune hepatitis (AIH) like PSC-AIH or AIH-overlap disorder. Hepatologists and Gastroenterologists often consider these combined conditions as distinctly different from the classical forms in isolation. Here, we review recent epidemiologic observations and highlight that PSC-IBD and PSC-AIH overlap appear to represent aspects of a common PSC clinico-pathological pathway and manifest in an age-of-presentation dependent manner...

Systemic lupus erythematosus (SLE), an autoimmune disease, is among the most prevalent rheumatic autoimmune disorders. It affects autologous connective tissues caused by the breakdown of self-tolerance mechanisms. During the last two decades, stem cell therapy has been increasingly considered as a therapeutic option in various diseases, including parkinson's disease, alzheimer, stroke, spinal cord injury, multiple sclerosis, inflammatory bowel disease, liver disease, diabete, heart disease, bone disease, renal disease, respiratory diseases, and hematological abnormalities such as anemia...

Macrophage activation syndrome (MAS) is a rare complication of autoimmune inflammatory rheumatic diseases (AIIRD) characterized by a progressive and life-threatening condition with features including cytokine storm and hemophagocytosis. Predisposing factors are typically associated with microbial infections, genetic factors (distinct from typical genetically related hemophagocytic lymphohistiocytosis (HLH)), and inappropriate immune system overactivation. Clinical features include unremitting fever, generalized rash, hepatosplenomegaly, lymphadenopathy, anemia, worsening liver function, and neurological involvement...

BACKGROUND: Organ-specific immunological disorders involving organ/gland like the thyroid, liver, muscles, pancreas, etc., is a result of autoimmunity which can be with or without association with systemic immunological disorders. The thyroid gland is most commonly involved. We evaluated thyroid dysfunction and ESR among various immunological disorders and their correlation with disease activity and hemoglobin respectively. MATERIAL AND METHODS: A cross-sectional/observational study was conducted by including 110 patients with different immunological disorders who came in as in-patients and outpatients in our institute for 18 months and various data were collected and evaluated to analyze the targeted parameters among the study group...

BACKGROUND: Autoimmune hepatitis (AIH), primarily mediated by T cells, is characterized by liver inflammation. Despite the advancements in understanding its pathogenesis, effective therapeutic options are limited. Naringin, a flavonoid abundant in citrus fruits, is recognized for its anti-inflammatory properties and ability to protect against various inflammatory diseases, including drug-induced liver injury. However, the exact effects of naringin on AIH and the mechanisms involved remain poorly understood...
