Vedolizumab is a humanized IgG1 monoclonal antibody that selectively blocks the lymphocyte integrin α4β7 and prevents its interaction with endothelial adhesion molecules and subsequent transmigration to the gastrointestinal tract. The drug was approved in 2014 for the induction and maintenance treatment of ulcerative colitis and moderate to severe Crohn's disease that is refractory or intolerant to conventional treatment with corticoids and immunosuppressants and/or anti-TNFα drugs. However, inflammatory bowel disease has a variable behavior following liver transplant...

Monoamine oxidase A (MAOA) is a mitochondrial enzyme that catalyzes oxidative deamination of neurotransmitters and dietary amines and produces H2 O2. It facilitates the progression of gliomas and prostate cancer, but its expression and functional relevance have not been studied in lymphoma. Here, we evaluated MAOA in 427 cases of Hodgkin and non-Hodgkin lymphoma and in a spectrum of reactive lymphoid tissues by immunohistochemistry on formalin-fixed paraffin-embedded specimens. MAOA was expressed by Hodgkin Reed-Sternberg (HRS) cells in the majority of classical Hodgkin lymphomas (cHL) (181/241; 75%), with 34...

Mutations in TYROBP and TREM2 have been shown to cause polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy. Recently, variants in TREM2 were also associated with frontotemporal dementia and Alzheimer's disease. Given the functional proximity between these 2 genes, we investigated the genetic variation of TYROBP in a Turkish cohort of 103 dementia patients. No mutations or copy number variants predicted to be pathogenic were identified. These results indicate that mutations in TYROBP are not a common cause of dementia in this Turkish cohort...

BACKGROUND: Monoclonal immunoglobulin deposition disease (MIDD) is characterized by the non-amyloid deposition of monoclonal immunoglobulin fragments in the basement membranes. Heavy chain deposition disease (HCDD) is a type of MIDD. HCDD is an extremely rare disease, and only three cases have been reported in Japan up to the present. The prognosis of HCDD is very poor, and optimal treatment has not been established. Only a few cases of HCDD with favorable long-term renal prognosis have been reported to date...

We report a 12-year-old boy with human immunodeficiency virus (HIV) who presented with rapidly progressive difficulty in ambulation. The symptoms started to worsen when he was put on antiretroviral therapy (ART). Our findings show that the dynamics of HIV-related immune suppression and highly active antiretroviral therapy (HAART) have an impact on the clinical course of Subacute sclerosing panencephalitis (SSPE). Slow progression is expected in children on HAART but in our case, we observe a complex interaction of the virus with the immune system and modification of disease course of SSPE with ART...

Inflammatory bowel disease (IBD) with its 2 most common entities, ulcerative colitis and Crohn's disease, causes an increased risk of developing intestinal cancers. In fact, malignancies are the second most common cause of death after cardiovascular diseases in both sexes of patients with IBD. Risk factors for colorectal cancer in IBD correlate with the duration of the disease, extent of disease, the association with primary sclerosing cholangitis, family history, and early age at onset. Patients with IBD also have an increased risk for developing a variety of extraintestinal malignancies...

Cholangiopathies encompass a heterogeneous group of disorders affecting biliary epithelial cells (i.e. cholangiocytes). Early diagnosis, prognosis and treatment still remain clinically challenging for most of these diseases and are critical for adequate patient care. In the past decade, extensive research has emphasized microRNAs (miRs) as potential non-invasive biomarkers and tools to accurately identify, predict and treat cholangiopathies. MiRs can be released extracellularly conjugated with lipoproteins or encapsulated in extracellular vesicles (EVs)...

In rare cases, measles virus (MV) in children leads to fatal neurological complications such as primary measles encephalitis, post-acute measles encephalitis, subacute sclerosing panencephalitis and measles inclusion-body encephalitis. To investigate the pathogenesis of MV-induced encephalitis, rodent brain-adapted MV strains CAM/RB and CAMR40 were generated. These strains acquired mutations to adapt to the rodent brain during 40 passages in rat brain. However, it is still unknown which genes confer the neurovirulence of MV...

BACKGROUND: Liver transplant (LT) recipients with autoimmune liver disease (primary sclerosing cholangitis, primary biliary cholangitis, autoimmune hepatitis) are at increased risk of developing acute cellular rejection (ACR), and in many cases graft failure due to recurrent disease. We describe our experience with dual immunosuppression without steroid maintenance and analyze its effect on disease recurrence; ACR; patient and graft survivals; and complications, such as sepsis and de novo malignancy...

Craniometaphyseal Dysplasia (CMD) is a sclerosing osseous dysplasia characterised by hyperostosis of craniofacial and long bones, resulting in distortion and cranial nerve palsies. We present a case report on the management of a 63 year old female with Craniometaphyseal Dysplasia. This report describes an additional clinical manifestation of hypercementosis, which although well recognised in other sclerosing osseous dysplasias, is not reported in the literature for Craniometaphyseal Dysplasia. We discuss established in vivo studies in mice which link the genetic mutations found in Craniometaphyseal Dysplasia to hypercementosis, and how this report describes the same manifestation in humans...

PURPOSE OF REVIEW: Cholangiocarcinoma is a devastating, unpredictable complication of large duct primary sclerosing cholangitis (PSC), which occurs in 5-15% of patients. The aim of this review is to discuss whether dominant strictures (DS) occurring in the larger bile ducts in PSC are a risk factor for the development of cholangiocarcinoma. RECENT FINDINGS: The development of DS is related to specific genetic polymorphisms affecting the innate immune system and the microbiome...

Atypical lipomatous tumor/well-differentiated liposarcoma/dedifferentiated liposarcoma (ALT/WDL/DDL) is a common type of liposarcoma in late adulthood. However, pediatric ALT/WDL/DDL is extremely rare, and only 3 cases have been described in children younger than 10years of age. Notably, none of these cases harbored MDM2 gene amplification. Here, we reported a sclerosing ALT/WDL in a 7-year-old Chinese girl. Histologically, in most areas, the neoplastic cells were embedded within the collagenous background and typical lipogenic areas were inconspicuous throughout the sclerotic areas...

The ultrasound-guided foam sclerotherapy (UGFS) involves the injection of a sclerosing agent into a target vein under ultrasonographic guidance. The goal of this treatment is to harm the venous endothelium to achieve the destruction of the vein wall by a fibrosis phenomenon. In this article, we discuss indications and contraindications of UGFS. We also describe the technique, its efficacy and its complications.

REVIEW

Cholestatic liver diseases, including primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC), are manifested as an impairment of normal bile flow and excessive accumulation of potentially toxic bile acids. Endogenous bile acids are involved in the pathogenesis and progression of cholestasis. Consequently, chronic cholestasis affects the expression of bile acids transporters and nuclear receptors, and results in liver injury. Several lines of evidence suggest that intestinal microbiota plays an important role in the etiopathogenesis of cholestatic liver diseases by regulating metabolism and immune responses...

Sclerosing epithelioid fibrosarcoma (SEF) is an aggressive neoplasm thought to be related to low-grade fibromyxoid sarcoma, which typically occurs in middle-aged adults in the deep soft tissues of the lower extremities and trunk. It comprises nests and cords of relatively uniform epithelioid polygonal cells with clear or eosinophilic cytoplasm in densely sclerotic stroma, and it is typically associated with EWSR1 gene rearrangements, and most commonly EWSR1-CREB3L1 fusions. As primary SEF can arise in bone, and bone is also a common metastatic site for SEF, its recognition at this site is important...

Sclerosing angiomatoid nodular transformation (SANT) is a rare, benign, proliferative vascular lesion that arises from the splenic red pulp. Most patients with SANT have no clinical symptoms and are discovered incidentally on imaging. There are no definitive radiological signs and a distinction from other splenic diseases, and malignant processes remain difficult. Confirmation of the diagnosis of SANT requires a histological and immunohistochemical evaluation of the resected spleen. Here, we report an unusual case of SANT of the spleen successfully treated with an elective laparoscopic splenectomy (LS)...

Primary sclerosing cholangitis (PSC) is strongly associated with several human leukocyte antigen (HLA) haplotypes. Due to extensive linkage disequilibrium and multiple polymorphic candidate genes in the HLA complex, identifying the alleles responsible for these associations has proven difficult. We aimed to evaluate whether studying populations of admixed or non-European descent could help in defining the causative HLA alleles. When assessing haplotypes carrying HLA-DRB1*13:01 (hypothesized to specifically increase the susceptibility to chronic cholangitis), we observed that every haplotype in the Scandinavian PSC population carried HLA-DQB1*06:03...

Secondary sclerosing cholangitis (SSC) is a term used for a group of chronic cholestatic disease affecting the intra- and/or extrahepatic biliary tree with inflammation and progressive stricture formation, which can lead to biliary cirrhosis. A newly recognized form of SSC is secondary sclerosing cholangitis in critically ill patients (SSC-CIP). Pathogenesis is believed to involve ischemic injury of intrahepatic bile ducts associated with prolonged hypotension, vasopressors administration, and/or mechanical ventilation in patients treated in the intensive care unit (ICU)...

BACKGROUND AND AIMS: Dual red imaging (DRI) is a novel image-enhanced endoscopy technique that can increase the visibility and predict the depth of esophageal varices (EVs). The recurrence rate of EVs after endoscopic injection sclerotherapy (EIS) reportedly decreases by intravariceal injection of a sclerosant. We evaluated prospectively whether the EIS success rate was increased by DRI compared with the white light (WLI) mode. METHODS: A total of 79 EV patients were randomly divided into the DRI (n = 40) and WLI (n = 39) groups...

Cholangiocarcinoma (CCA) is a relatively rare primary malignancy, with established risk factors that include primary sclerosing cholangitis, choledochal cysts and hepatolithiasis. In the present study, two cases of CCA, which occurred following abdominal external beam radiotherapy (EBRT) for non-Hodgkin's lymphoma, are reported. Case 1 and 2 were diagnosed with cholangiocarcinoma 30 and 4 years following treatment with combined chemotherapy and abdominal radiotherapy treatment, respectively. The patients received chemotherapy as treatment of cholangiocarcinoma; however, whilst their symptoms improved, they succumbed within 12 and 2 months respectively following the diagnosis with cholangiocarcinoma...
