Human herpesvirus 6 (HHV-6A and HHV-6B) can cause primary infection or reactivate from latency in liver transplant recipients, which can result in a variety of clinical syndromes, including fever, hepatitis, encephalitis, and higher rates of graft dysfunction as well as indirect effects including increased risks of mortality, CMV disease, hepatitis C progression and greater fibrosis scores. Although HHV-6 infection is currently diagnosed by quantifying viral DNA in plasma or blood, biopsy to demonstrate histopathologic effects of HHV-6 remains the gold standard for diagnosis of end-organ disease...

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disorder, tightly associated with obesity. The histological spectrum of the disease ranges from simple steatosis to steatohepatitis, with different stages of fibrosis, and fibrosis stage is the most significant predictor of mortality in NAFLD. Liver biopsy continues to be the gold standard for its diagnosis and reliable non-invasive diagnostic tools are unavailable. We investigated the accuracy of candidate proteins, identified by an in silico approach, as biomarkers for diagnosis of fibrosis...

Early indication of late-stage failure of novel candidate drugs could be facilitated by continuous integration, assessment, and transfer of knowledge acquired along pharmaceutical development programs. We here present a translational systems pharmacology workflow that combines drug cocktail probing in a specifically designed clinical study, physiologically based pharmacokinetic modeling, and Bayesian statistics to identify and transfer (patho-)physiological and drug-specific knowledge across distinct patient populations...

BACKGROUND & AIMS: Macrophage migration inhibitory factor (MIF) is a multi-potent cytokine that contributes to the inflammatory response to injury. MIF is expressed by multiple cell types; however, the cellular source and actions of MIF in alcoholic liver disease (ALD) are not well known. Here we tested the hypothesis that non-myeloid cells, specifically hepatocytes, are an important cellular source of MIF in ALD. METHODS: MIF expression was measured in HuH7 and differentiated THP-1 cells in response to ethanol...

Alcoholic hepatitis (AH) is the most severe form of alcoholic liver disease. Most studies have focused on short-term prognosis, while factors associated with long-term survival are largely unknown. THE AIMS OF OUR STUDY WERE: 1) to determine the impact of complete abstinence from alcohol on long-term survival and 2) to identify prognostic factors at admission capable of predicting abstinence during long-term follow-up in patients with AH. One hundred and forty-two patients with biopsy-proven AH that survived the first episode were included...

We experienced a 38-year-old Japanese male with t(10;19) CIC-DUX4 -positive undifferentiated small round cell sarcoma in the deep abdominal wall. Three months before his first visit to our hospital, he noticed a mass in his right abdominal wall. Computed tomography on admission revealed a solid abdominal tumor 70×53mm in size and multiple small tumors in both lungs. The biopsy of the abdominal tumor revealed undifferentiated small round cell sarcoma, suggestive of Ewing sarcoma. Under the clinical diagnosis of Ewing-like sarcoma of the abdominal wall with multiple lung metastases, several cycles of ICE (ifosfamide, carboplatin and etoposide) therapy were performed...

CONTEXT: Extra-gastrointestinal stromal tumors (E-GIST) presenting in the liver are exceedingly rare and raise difficult diagnostic and therapeutic challenges. METHODS: We report on two cases of liver E-GIST with different clinical presentations. We describe their clinical and imaging features, their histopathological and molecular characteristics, their treatment and their course. RESULTS: The first case was that of a 56-year-old male presenting with a 10-cm liver mass; the initial diagnosis, made in 1986 from a biopsy sample, was leiomyosarcoma; liver transplantation was performed in 1987; no extra-hepatic tumor was found; the course was uneventful until 1999, when tumor recurrence was diagnosed along the initial biopsy route; after reevaluation of available material, the definitive pathological diagnosis was GIST; imatinib treatment resulted in major response; the patient died of end-stage kidney disease 22 years after the initial diagnosis and 9 years after tumor recurrence...

BACKGROUND: Metastatic uveal melanoma is a highly fatal disease; most patients die from their hepatic metastasis within 1 year. A major drawback in the development of new treatments for metastatic uveal melanoma is the difficulty in obtaining appropriate cell lines and the lack of appropriate animal models. Patient-derived xenograft (PDX) tumor models, bearing ectopically implanted tumors at a subcutaneous site, have been developed. However, these ectopically implanted PDX models have obstacles to translational research, including a low engraftment rate, slow tumor growth, and biological changes after multiple passages due to the different microenvironment...

OBJECTIVE: Animal models and studies in adults have demonstrated that copper restriction increases severity of liver injury in nonalcoholic fatty liver disease (NAFLD). This has not been studied in children. We aimed to determine if lower tissue copper is associated with increased NAFLD severity in children. METHODS: This was a retrospective study of pediatric patients who had a liver biopsy including a hepatic copper quantitation. The primary outcome compared hepatic copper concentration in NAFLD versus non-NAFLD...

Liver biopsy is a valuable tool. Even though outpatient liver biopsies are routinely performed in adults, there are no clear recommendations on its safety and feasibility in children. We reviewed the records of children who underwent a percutaneous liver biopsy at our institution between January 2005 and June 2015. A total of 626 biopsies were performed on 497 patients (250 boys, median age 6 [0.2-19.3] years). Abnormal liver function tests for investigation 288 (46%) was the most common indication. Thirty (4...

A 57-year-old man presented to the surgical oncology clinic with a mildly tender mass under his right arm. Four years prior, the patient had a melanoma removed from his right shoulder along with an ipsilateral right axillary sentinel lymph sampling. Computed tomography (CT) scan was negative for metastatic disease at that time. The patient did not undergo completion axillary node dissection and was lost to follow-up. The patient was originally from Australia, did not tan but reported multiple sunburns before age 18...

Metastatic esophageal adenocarcinoma to the urinary bladder is extremely rare. We describe a previously healthy 49-year-old female with recent diagnosis of adenocarcinoma of the gastroesophageal junction with metastatic disease to the liver. Biopsy was positive for human epidermal growth factor receptor 2 (HER2) by Fluorescence In Situ Hybridization (FISH). She received six cycles of Cisplatin, 5-Fluorouracil, and Herceptin and subsequently developed symptomatic anemia and hematuria. Cystoscopy with retroflexion was performed and she received a transurethral resection of bladder tumor with fulguration...
