Kikuchi-Fujmoto disease (KFD), also known as "histiocytic necrotizing lymphadenitis", is a rare lymphadenitis of unknown origin, but with an excellent prognosis. It is more common in Asia, but isolated cases are also reported in America, Africa and Europe. The disease can have an acute or subacute course, usually develops in 1 to 3 weeks, with spontaneous resolution in 1-4 months. The main clinical sign is cervical lymphadenopathy, especially in the posterior cervical triangle with bulky and painful lymph nodes, usually affecting only one side; rare cases of generalized lymphadenopathy can be seen...

BACKGROUND In patients with the diagnosis of autoimmune hepatitis (AIH), the presence of cholestatic features raise the possibility of an overlap syndrome with primary sclerosing cholangitis (PSC). Here, we present a unique case with AIH-PSC overlap syndrome and innumerable liver masses. CASE REPORT A 26-year-old man presented with generalized icterus. Based on the serological findings of hypergamainmunoglobulinemia and positive anti-nuclear antibody tests, together with an abnormal cholangiogram, he was diagnosed with overlap syndrome (AIH-PSC)...

BACKGROUND: Luminex panel reactive antibody (PRA) screening assays using microbeads are widely used for organ transplantation. Anti-HLA serum reactivity is calculated by correcting for non-specific binding to the negative control (NC) beads. High mean fluorescence intensity (MFI) value of NC beads are observed in some patients and can result in false negative results in the PRA screening assay. We analyzed the clinical characteristics and HLA types of those patients with high MFI values of NC beads...

BACKGROUND: Collection and testing of individual serum samples are often used in research to gain knowledge about e.g. the humoral response against bacteria or virus. This is a valid but time-consuming method and might be a waste of valuable serum samples for inefficient research. So far, no study has considered using serum pools as a quick and efficient screening method to confirm or deny hypotheses. METHODS: We created serum pools from four different patient groups (systemic lupus erythematosus n=85, rheumatoid arthritis n=77, Sjögren's syndrome n=91, systemic sclerosis n=66) and one healthy control group (n=67)...

OBJECTIVE: Incomplete lupus erythematosus (ILE) involves clinical and/or serologic manifestations consistent with but insufficient for SLE classification. Because the nature of ILE is poorly understood and no treatment recommendations exist, we examined clinical manifestations, medication history, and immunologic features in a diverse collection of ILE and SLE patients. METHODS: Medical records of subjects enrolled to the Lupus Family Registry and Repository were reviewed for medication history and American College of Rheumatology (ACR) classification criteria to identify ILE patients (3 ACR criteria; n=440) and SLE patients (≥4 ACR criteria; n=3,397)...

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...

Despite the great potential of antibodies as intracellular therapeutics, there is a significant, unmet challenge in delivering sufficient amounts of folded antibodies inside cells. We describe an all-protein self-assembled nanocarrier capable of delivering functional antibodies to the cytosol. By combining an α-helical peptide that self-assembles into a hexameric coiled-coil bundle and an Fc-binding Protein A fragment, we generated the Hex nanocarrier that is efficiently internalized by cells without cytotoxicity...

The etiology of chronic bile duct injury and fibrosis in patients with autoimmune cholestatic liver diseases is complex, and likely involves immune cells such as lymphocytes. However, most models of biliary fibrosis are not autoimmune in nature. Biliary fibrosis can be induced experimentally by prolonged exposure of mice to the bile duct toxicant alpha-naphthylisothiocyanate (ANIT). We determined whether lymphocytes contributed to ANIT-mediated biliary hyperplasia and fibrosis in mice. Hepatic accumulation of T-lymphocytes and increased serum levels of anti-nuclear-autoantibodies were evident in wild-type mice exposed to ANIT (0...

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease involving multiple organs and tissues, which is characterized by the presence of excessive anti-nuclear autoantibodies. The pathogenesis of SLE has been intensively studied but remains far from clear. Increasing evidence has shown that the genetic susceptibilities and environmental factors-induced abnormalities in immune cells, dysregulation of apoptosis, and defects in the clearance of apoptotic materials contribute to the development of SLE...

Primary biliary cholangitis (PBC), formerly referred to as primary biliary cirrhosis, is an infrequent progressive intrahepatic cholestatic autoimmune illness that can evolve into hepatic fibrosis, hepatic cirrhosis, hepatic failure, and, in some cases, hepatocellular carcinoma. The disease itself is characterized by T-lymphocyte-mediated chronic non-suppurative destructive cholangitis and elevated serum levels of extremely specific anti-mitochondrial autoantibodies (AMAs). In this article, we will not only review epidemiology, risk factors, natural history, predictive scores, radiologic approaches (e...

Drug Induced Lupus Erythematous (DILE) is a rare adverse reaction to a large variety of drugs including Isoniazid (INH), with features resembling idiopathic Systemic Lupus Erythematosus (SLE). Diagnosis require identification of a temporal relationship between drug administered and symptom. It is an idiosyncratic reaction, with no pre-existing lupus. Our case highlights a rare presentation of isoniazid induced lupus with profound pancytopenia and mucosal ulcers, thus posing a diagnostic challenge. The patient was on multidrug treatment for pulmonary and knee joint tuberculosis...

High mobility group box 1 (HMGB1) is tightly connected to the process of tissue organization upon tissue injury. Here we show that HMGB1 controls epithelium and connective tissue regeneration both in vivo and in vitro during palatal wound healing. Heterozygous HMGB1 (Hmgb1(+/-)) mice and Wild-type (WT) mice were subjected to palatal injury. Maxillary tissues were stained with Mallory Azan or immunostained with anti-HMGB1, anti-proliferating cell nuclear antigen (PCNA), anti-nuclear factor-κB (NF-κB) p50 and anti-vascular endothelial growth factor (VEGF) antibodies...
