Pancreaticobiliary complications following various surgical procedures, including liver transplantation, are not uncommon and are important causes of morbidity and mortality. Therapeutic endoscopy plays a substantial role in these patients and can help to avoid the need for reoperation. However, the endoscopic approach in patients with surgically altered gastrointestinal (GI) anatomy is technically challenging because of the difficulty in entering the enteral limb to reach the target orifice to manage pancreaticobiliary complications...

Norovirus is a common self-limiting gastrointestinal infection, but in transplant recipients, symptoms can last for months and result in serious health complications. As there is currently no established treatment for chronic norovirus infection in transplant patients, management has been directed at symptom control, trial of various antivirals, and ultimately reductions in immunosuppression. We present 3 cases of chronic norovirus infection in cardiac transplant patients to illustrate various approaches to diagnosis, the prolonged nature of disease symptoms, and treatment options...

Behçet disease (BD) is rarely seen in children. Its clinical manifestations are believed to differ between pediatric and adult patients. The characteristics of BD complicated by myelodysplastic syndrome (MDS) are well established for adult patients; however, because only a few cases of pediatric-onset BD complicated by MDS have been reported, its clinical characteristics remain unknown. We here retrospectively review pediatric-onset BD complicated by myeloid malignancies in Japan, having identified five such patients...

Allogeneic stem cell transplantation is used in the treatment of younger patients with severe hematological diseases, especially hematological malignancies, and acute graft versus host disease (GVHD) is then an important immune-mediated posttransplant complication. Several risk factors for acute GVHD have been identified, including pretransplant factors that possibly influence the posttranspant course through their effects on host immunocompetent cells. Metabolic regulation is important for immunoregulation, and we therefore investigated whether the pretransplant metabolic status of allotransplant recipients was associated with later acute GVHD...

Lysosomal acid lipase deficiency (LAL-D) is a rare disorder of cholesterol metabolism with an autosomal recessive mode of inheritance. The absence or deficiency of the LAL enzyme gives rise to pathological accumulation of cholesterol esters in various tissues. A severe LAL-D phenotype manifesting in infancy is associated with adrenal calcification and liver and gastrointestinal involvement with characteristic early mortality. LAL-D presenting in childhood and adulthood is associated with hepatomegaly, liver fibrosis, cirrhosis, and premature atherosclerosis...

Around 400 million people worldwide suffer from diabetes mellitus. The major pathological event for Type 1 diabetes and advanced Type 2 diabetes is loss or impairment of insulin-secreting β cells of the pancreas. For the past 100 years, daily insulin injection has served as a life-saving treatment for these patients. However, insulin injection often cannot achieve full glucose control, and over time poor glucose control leads to severe complications and mortality. As an alternative treatment, islet transplantation has been demonstrated to effectively maintain glucose homeostasis in diabetic patients, but its wide application is limited by the scarcity of donated islets...

PURPOSE: Gastroparesis is a frequent gastrointestinal complication after lung transplantation. Although gastric emptying scintigraphy (GES) is the standard technique to evaluate gastroparesis, magnetic resonance imaging (MRI) can also assess gastric motility and emptying. This study compared the results obtained by these two modalities. METHODS: Twenty-two lung transplant recipients underwent MRI and GES after ingesting a small pancake as a test meal. Parameters assessed on MRI included antral peristaltic wave velocity and frequency, and the ratios of gastric content volume at 15 and 35 min...

OBJECTIVES: Gastrointestinal infections by cytomegalovirus (CMV) and adenovirus may complicate hematopoietic stem cell transplantation (HSCT). Although CMV and adenovirus produce recognizable cytopathic changes, these changes may be subtle or focal. The value of viral immunohistochemistry in detecting infection in HSCT recipients when cytopathic changes are not identified has not been demonstrated. METHODS: H&E-stained sections from gastrointestinal biopsy specimens were reviewed by three pathologists...

A 59-year-old patient with multiple myeloma on maintenance chemotherapy presented with fever, weight loss, and night sweats. An F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) computed tomography (CT) showed intra-abdominal lymphadenopathy with a mesenteric mass that led to further workup and diagnosis of histoplamosis. The patient was treated with amphotericin B and subsequently switched to itraconazole. This exemplifies the usefulness of FDG PET CT in diagnosis of infectious complications...

Modern immunosuppressive therapy has produced a real revolution in renal and organ transplantation but it comes with the price of multiple side effects. There are many gastrointestinal (GI) complications that are the consequence of transplant immunosuppressant medication. In fact, for any immunosuppressant therapy, certain standardized precepts and attitudes that aim to reduce the incidence and the impact of the medication side effects must be applied. Many patients undergo renal transplantation and the physicians have to be aware of the advantages and the risks associated...

Cystic fibrosis (CF) is an autosomal recessive genetic disease that occurs in approximately 1 in 2,500 white live births. It is less common in nonwhite individuals. A dysfunctional epithelial chloride channel leads to excessively thick mucus affecting multiple organ systems. Common issues include mucous plugging of the airway, lung inflammation, chronic pulmonary infections, intestinal malabsorption, and malnutrition. Universal screening of newborns for CF is recommended in many countries. CF can be diagnosed based on clinical evidence of disease along with genetic testing or other laboratory evidence of chloride channel dysfunction...

Graft-versus-host disease (GVHD) and infection are major complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the leading causes of morbidity and mortality in HSCT patients. Recent work has demonstrated that the two complications are interdependent. GVHD occurs when allo-reactive donor T lymphocytes are activated by major histocompatibility antigens or minor histocompatibility antigens on host antigen-presenting cells (APCs), with the eventual attack of recipient tissues or organs...

Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT) leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound...

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (HSCT) is potentially curative in a variety of hematological malignancies. Graft-vs.-host disease (GvHD) remains a life-threatening complication. Standard treatment is high-dose (HD) corticosteroids. Steroid-refractory (SR) GvHD is associated with poor prognosis. At present, second-line treatment is ill-defined and includes a number of agents. Novel insights into the pathophysiology of acute GvHD (aGvHD) highlight the relevant role of the host inflammatory response governed by several kinase families, including Janus kinases (JAK)1/2...
