BACKGROUND AND AIMS: Acute graft-versus-host disease (GVHD) is a major complication after allogeneic hematopoietic stem cell transplantation, which often targets gastrointestinal (GI) tract. Osteopontin (OPN) plays an important physiological role in the efficient development of Th1 immune responses and cell survival by inhibiting apoptosis. The role of OPN in acute GI-GVHD is poorly understood. In the present study, we investigated the role of OPN in donor T cells in the pathogenicity of acute GI-GVHD...

BACKGROUND: Infants presenting with lysosomal acid lipase deficiency have marked failure to thrive, diarrhea, massive hepatosplenomegaly, anemia, rapidly progressive liver disease, and death typically in the first 6 months of life; the only available potential treatment has been hematopoietic stem cell transplantation, which is associated with high morbidity and mortality in this population. The study objective was to evaluate safety and efficacy (including survival) of enzyme replacement with sebelipase alfa in infants with lysosomal acid lipase deficiency...

BACKGROUND Acute graft-versus-host disease (aGVHD) remains the most common and challenging complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). An important obstacle to the therapeutic effect of aGVHD is the inability to identify risk factors for an individual patient at the onset of symptoms. We performed a retrospective study with the aim of defining clinically meaningful pre-transplantation risk factors for grades II-IV aGVHD patients. MATERIAL AND METHODS To identify pre-transplantation risk factors for grades II-IV aGVHD after allo-HSCT, we performed a retrospective study in 292 patients who underwent allo-HSCT at our center from January 2010 to July 2015...

: 269 Background: Hospital readmission rate is increasingly suggested as a quality care metric. Currently there are no standard criteria for an avoidable readmission in oncology. Although patients with cancer have been identified as being at increased risk of readmission, there has been little to examine the reasons for the oncology patient readmission. The aim was to examine the profiles of patients with an unplanned readmission within 30 days after discharge by an oncology provider and to measure the unplanned 30-day readmission rate...

The GI-tract is a major target for both the intensive chemo and/or radiotherapy conditioning as well as for GVHD and therefore is closely associated with transplant outcome. Apart from being a target, the GI-tract is also a mediator and therefore is also a key player of the pathogenetic process following allogeneic transplantation. Areas covered: The intestinal homeostasis is regulated through complicated interactions between the key players of this process which are the intestinal epithelium, the intestinal immune system, and the intestinal microbiota...

Crohn's disease which mainly affects the gastrointestinal tract and impairs patient's quality of life, is a refractory inflammatory disease with clinical manifestations of abdominal pain, fever, bowel obstruction and diarrhoea with blood or mucus. Besides the common complication of intestinal obstruction, the formation of fistulas should also be concerned about and anorectal fistula is the most typical. The disease is difficult to radical cure and easy to relapse, which urges people to find other effective treatment in addition to surgery...

Diarrhea constitutes a frequent and often debilitating complication of allogeneic hematopoietic cell transplantation (alloHCT). Especially when accompanied by jaundice, skin rash, and symptoms of the upper gastrointestinal tract, diarrhea strongly suggests emergence of acute graft-versus-host disease (GvHD), which is a serious immune complication of the procedure, with possible fatal consequences. However, especially when diarrhea occurs as an isolated symptom, the other causes must be excluded before initiation of GvHD treatment with immune-suppressive drugs...

The lung transplantation is a therapeutic procedure indicated for lung diseases that are terminal and irreversible (except lung cancer) despite the best medical current treatment. It is an emergent procedure in medical care. In this review, an analyse is made of the most frequent complications of lung transplant related to the graft (rejection and chronic graft dysfunction), immunosuppression (infections, arterial hypertension, renal dysfunction, and diabetes), as well as others such as gastrointestinal complications, osteoporosis...

Thrombotic complications are a significant source of morbidity and mortality following hematopoietic stem cell transplants. Among them, transplant-associated thrombotic microangiopathy (TA-TMA) is a well-recognized syndrome that can affect various organ systems. Its etiology is related to endothelial injury accompanied by complement activation. As many of the signs and symptoms of the disease are also encountered in other complications following hematopoietic stem cell transplant, it can often be difficult to establish the diagnosis based on clinical data alone...

INTRODUCTION: Stem cell transplantation is today's procedure of choice for management of various hematopoietic malignant and severe immunogenic disorders. High Resolution Computed Tomography (HRCT) is a common technique for the diagnosis of pulmonary complications in stem cell transplant recipients. There are a large number of complications which can complicate the post-transplant period. AIM: To study the role of HRCT chest in stem cell transplant patients developing pulmonary complications, detect any evidence of infection, detect clinical signs of lung infections, Graft versus Host Disease (GvHD) or other regimen related toxicities outlined earlier, detect any evidence of GvHD and correlate these clinical signs with radiological changes in the lungs...

The use of continuous-flow left ventricular assist devices (CF-LVADs) has revolutionized the landscape of mechanical circulatory support for patients with heart failure. Clinical trials are already testing the next generation of CF-LVADs. In this study, our objective was to review our long-term experience with the current generation of CF-LVADs, specifically, the HeartMate (HM) II (Thoratec Corp, Pleasanton, CA). In this single-center retrospective analysis, we evaluated the records of 278 consecutive patients who underwent a total of 302 HM II placements from June 2005 through June 2014...

BACKGROUND: Intestinal transplantation is a procedure which inflicts immunological and infectious complications that affect the transplanted graft, posing both diagnostic and therapeutic challenges. Video capsule endoscopy (VCE) offers easy access to the entire small intestine and presents itself as an interesting option. However, at present, no studies evaluating the usefulness of video capsule endoscopies in this setting have been published. Our aim was to evaluate the usefulness of VCE in detecting complications that arise after intestinal transplantation...

Acute liver failure, also known as fulminant hepatic failure, is a rare life-threatening disease that has a high mortality rate and affects many organ systems. Causes of acute liver failure vary-it can be attributed to drugs, viruses, and other uncommon sources. Complications of liver failure can include encephalopathy, cerebral edema, sepsis, renal failure, gastrointestinal bleeding, and respiratory failure. Fortunately, with advances in critical care medicine and emergent liver transplant, mortality rates have decreased in the past decade...

Among infants, almost half of acute liver failure cases are classified as indeterminate, whereas only a small number of cases show a documented viral infection. We present the first reported case of isolated acute hepatic failure in an infant in the setting of a human parechovirus (HPeV) infection. HPeV also may have been contributory to the posttransplant complication of 2 intussusceptions. This is a 10-month-old girl who presented with only symptoms of fussiness and was noted to have progressive decline in synthetic liver function as well as worsening coagulopathy requiring a liver transplant...

REVIEW
Tin Moe Wai, Eun Young Kim
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...
