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...

BACKGROUND AND AIMS: Ten percent to 20% of children with autoimmune hepatitis (AIH) require second-line therapy to achieve remission. Although current guidelines exist on first-line management, evidence for second-line therapy in treatment-refractory patients is lacking. Our aim was to perform a systematic review and meta-analysis of the efficacy and safety of second-line treatments used in this population. METHODS: Electronic and manual searches were used to identify potential studies for inclusion...

In patients with inflammatory bowel disease (IBD) there is an increased incidence of thromboembolic events. We report a case of a female, age 14, with a 6 months history of diarrhea with occasional presence of red blood and with a very distended abdomen with evident ascites. The diagnosis was Budd-Chiari syndrome (BCS) in ulcerative colitis (UC). Therapy with subcutaneous low molecular weight heparin, methylprednisolone, mesalazine was started. Clinical and radiological features quickly improved. No thrombophilia abnormality nor other risk factor for thrombosis were detected...

RATIONALE: Portal vein thrombosis is a complication after liver transplantation and cavernous transformation of the portal vein (CTPV) is a result of portal vein thrombosis, with symptoms of portal hypertension revealed by an enhanced CT scan. Meso-Rex bypass is an artificial shunt connecting the left portal vein to the superior mesenteric vein and is mainly used for idiopathic cavernomas. This technique is also used for post-transplant portal vein thrombosis in pediatric patients thereby bypassing obstructed sites of the extrahepatic portal vein...

Non-alcoholic fatty liver disease (NAFLD) is one of the most common complications of obesity. Several studies have shown that genetic predisposition probably plays an important role in its pathogenesis. In fact, in the last few years a large number of genetic studies have provided compelling evidence that some gene variants, especially those in genes encoding proteins regulating lipid metabolism, are associated with intra-hepatic fat accumulation. Here we provide a comprehensive review of the gene variants that have affected the natural history of the disease...

Acute iron poisoning may lead to life-threatening hepatotoxicity. We present the cases of two pediatric patients with hepatotoxicity following intentional iron ingestion that progressed rapidly to fulminant hepatic failure despite treatment with deferoxamine. Liver transplantation was lifesaving in both patients. These cases emphasize the need for a high index of suspicion for iron ingestion, close monitoring for liver toxicity, and timely consideration for liver transplantation.

BACKGROUND: Prostaglandins are often administered after liver transplantation (LT) to diminish ischemia-reperfusion injury (IRI), to favor liver recovery and to prevent vascular thrombosis. Possible beneficial effects in adult liver recipients are controversial, but the single existing pediatric small case series shows no significant impact of prostaglandin administration after LT. The purpose of this study was to analyze the effect of the prostaglandin dinoprostone in pediatric liver recipients...

Hepatic cytosolic alcohol and aldehyde dehydrogenases (ADHs and ALDHs) catalyze the biotransformation of xenobiotics (e.g., cyclophosphamide and ethanol) and vitamin A. Because age-dependent hepatic abundance of these proteins is unknown, we quantified protein expression of ADHs and ALDH1A1 in a large cohort of pediatric and adult human livers by LC-MS/MS proteomics. Purified proteins were used as calibrators. Two to three surrogate peptides per protein were quantified in trypsin digests of liver cytosolic samples and calibrator proteins under optimal conditions of reproducibility...

BACKGROUND: To test the hypothesis that infants born to obese women with pregestational type 2 diabetes mellitus (IBDM) have ventricular dysfunction at one month that is associated with markers of maternal lipid and glucose metabolism. METHODS: In a prospective observational study of IBDM (OB+DM, n=25), echocardiography measures of septal, left (LV) and right ventricular (RV) function and structure were compared at one month of age to infants born to OB mothers without DM (OB, n=24), and non-OB without DM (Lean, n=23)...

The frequency of hepatitis A virus and hepatitis E virus infections and their cytokine profiles were analyzed in Mexican pediatric patients with acute hepatitis. A high frequency of coinfections was found. Significant overexpression of interleukin (IL)-4, IL-12, IL-13 and interferon-gamma during hepatitis A virus monoinfections and limited secretion of cytokines in hepatitis E virus infections were observed.

John A Carter, Ryan Dammerman, Michael Frost
AIMS: Subdermal implantable buprenorphine (BSI) was recently approved to treat opioid use disorder (OUD) in clinically-stable adults. In the pivotal clinical trial, BSI was associated with a higher proportion of completely-abstinent patients (85.7% vs 71.9%; P = 0.03) versus sublingual buprenorphine (SL-BPN). Elsewhere, relapse to illicit drug use is associated with diminished treatment outcomes and increased costs. Herein, we evaluated the cost-effectiveness of BSI versus SL-BPN from a US societal perspective...

Recent developments regarding the treatment of pediatric liver tumors have significantly improved patient care. Stimulated by collaboration between international pediatric groups, advances have been made in surgical techniques, transplantation options, and chemotherapy schemas. In light of this progress, clear understanding of the state-of-the-art imaging evaluation of hepatobiliary tumors has become even more integral to the effective management of children with hepatic neoplasms. The unique imaging features of hepatic neoplasms in the pediatric population, when coupled with supportive demographic data and laboratory findings, can lead to accurate diagnosis and proper treatment of hepatobiliary tumors...

Esophageal varices are a serious consequence of portal hypertension in patients with chronic liver diseases. Several studies have evaluated possible noninvasive markers of esophageal varices to reduce the number of unnecessary endoscopies in patients with chronic liver disease. Aim of this study was to identify clinical and laboratory predictors of esophageal varices in children with chronic liver disease. This cross sectional observational study was done at Pediatric Gastroenterology and Nutrition Department of Bangabandhu Sheikh Mujib Medical University, Dhaka, over a period of 6 months...

Large-for-size syndrome (LFSS) is controversial in pediatric living donor liver transplantation patients and is associated with a poor graft outcome. Similar situations in deceased donor liver transplantation (DDLT) in adults have not been reported frequently, and there are no official guidelines worldwide. Deceased donation is extremely limited in Japan, and when a larger liver is allocated for a very sick small recipient in Japan, transplantation with a plan to address LFSS might be necessary. The patient is a 58-year-old female patient who had acute liver failure with coma...

Several novel single nucleotide polymorphisms (SNPs) involved in cytarabine cytotoxicity and related to clinical outcomes have been reported recently in a series of 232 pediatric patients with acute myeloid leukemia (AML). We report the first adult AML cohort in which the influence of these SNPs in cytarabine efficacy and toxicity was analyzed. Six of polymorphisms with clinical significance in the previous study [rs12036333, rs10758713, rs9883101, rs6550826, IRX2: rs2897047, mutated in colorectal cancers (MCC): rs7729269] were analyzed in a cohort of 225 adult patients at initial diagnosis of AML treated with an induction scheme of idarubicin plus cytarabine...

Cyclosporine A (CsA) is an immunosuppressive drug commonly used in organ transplant patients to prevent allograft rejections. Ketamine is a pediatric anesthetic that noncompetitively inhibits the calcium-permeable N-methyl-d-aspartic acid receptors. Adverse drug-drug interaction effects between ketamine and CsA have been reported in mammals and humans. However, the mechanism of such drug-drug interaction is unclear. We have previously reported adverse effects of combination drugs, such as verapamil/ketamine and shown the mechanism through intervention by other drugs in zebrafish embryos...

BACKGROUND: Although the epidemiology of hepatitis C virus (HCV) infection among children may be rapidly changing, few reports have characterized large nationwide cohorts of children with HCV infection. We, therefore, sought to clarify the epidemiology and natural history of HCV infection in Japanese children born over the last three decades. METHODS: Sixty-five pediatric centers retrospectively and prospectively recruited consecutive, otherwise-healthy HCV-infected children born during 1986 to 2015...
