Liver fibrosis is a disease that causes high morbidity and has become a major health problem. Liver fibrosis can lead to the end stage of liver diseases (livercirrhosisand hepatocellularcarcinoma). Currently, liver transplantation is the only effective treatment for end-stage liver disease. However, the shortage of organ donors, high cost of medical surgery, immunological rejection and transplantation complications severely hamper liver transplantation therapy. Mesenchymal stem cells (MSCs) have been regarded as promising cells for clinical applications in stem cell therapy in the treatment of liver diseases due to their unique multipotent differentiation capacity, immunoregulation and paracrine effects...

Small bowel transplantation is a life-saving surgery for patients with intestinal failure. The biggest problem in intestinal transplantation is graft rejection. Graft rejection is the main reason for morbidity and mortality. Rejection has a negative effect on the survival of the graft. While 50%-75% of small bowel transplantation patients experience acute rejection, chronic rejection occurs in approximately 15% of patients. Immune monitoring is crucial after small bowel transplantation. Unlike other types of transplantation, there are no non-invasive or reliable markers to predict rejection in small bowel transplantation...

Digestive graft versus host disease (GVHD) is a frequent complication after bone marrow transplantation (BMT), but small bowel obstruction is an extremely rare event. We present herein the first pediatric series of 4 cases of small bowel obstruction after BMT with detailed gross, histological data and their genetic status of the NOD2 gene. All patients had a history of severe acute GVHD treated by immunosuppressive agents and/or infliximab (in 3 cases). Acute or progressively worsening abdominal pain accompanied by small bowel occlusion occurred 5-16months after graft and CT-scan revealed multiple small intestinal stenosis...

Background Multiple myeloma is a haematological blood cancer of the bone marrow and is classified by the World Health Organisation (WHO) as a plasma cell neoplasm. In multiple myeloma, normal plasma cells transform into malignant myeloma cells and produce large quantities of an abnormal immunoglobulin called monoclonal protein or M protein. This ultimately causes multiple myeloma symptoms such as bone damage or kidney problems. The annual worldwide incidence of multiple myeloma is estimated to be 6 - 7/100,000 and accounts for 1% of all cancer...

Gastric antral vascular ectasia (GAVE), also known as "watermelon stomach", is an uncommon condition, which can cause gastrointestinal bleeding due to rupture of blood vessels that line the stomach. The pathogenesis of GAVE remains unclear; however it is thought that hemodynamic changes, mechanical stress, and autoimmune factors all have a part to play. A range of conditions are also commonly associated with the syndrome, such as portal hypertensive gastropathy, liver cirrhosis, and autoimmune disorders. Less commonly, chronic renal failure, cardiac diseases, and bone marrow transplantation have coexisted with GAVE...

BACKGROUND: Transplantation of fresh osteochondral allografts (OCAs) is an attractive treatment option for symptomatic articular cartilage lesions in young, healthy patients. Because the lack of OCA bone integration can be a cause of treatment failure, methods for speeding and enhancing OCA bone integration to mitigate this potential complication are highly desirable. PURPOSE: To determine if autogenous bone marrow aspirate concentrate (BMC) treatment of large femoral condylar OCAs would be associated with superior radiographic OCA bone integration compared with nontreated allografts during the critical first 6 months after surgery...

OBJECTIVES: Graft-versus-host disease after solid-organ transplant is exceedingly rare. Although the precise pathogenetic mechanisms are unknown, a progressive increase in donor chimerism is a requirement for its development. The incidence of mixed donor chimerism and its timeline after simultaneous pancreas-kidney transplant is unknown. MATERIALS AND METHODS: After encountering 2 cases of graft-versus-host disease after simultaneous pancreas-kidney transplant at our institution over a period of < 2 years, a collaborative pilot study was conducted by the bone marrow transplant, nephrology, and abdominal transplant surgery teams...

Patients who have undergone hematopoietic stem cell transplantation to treat underlying bone marrow pathology represent a unique and potentially high-risk patient population for total knee arthroplasty (TKA). This study retrospectively reviewed 15 TKA procedures performed on 11 patients with a history of hematopoietic stem cell transplantation. The authors analyzed patient survivorship; clinical outcomes, including complications; and implant survivorship. Mean follow-up was 5 years (range, 2-10 years). Patient survivorship free from mortality was 91% (95% confidence interval, 76%-100%) and 55% (95% confidence interval, 25%-85%) at 2 and 5 years, respectively...

INTRODUCTION: Patients with a history of chemotherapy or stem cell transplantation (SCT) and prolonged neutropenia are at risk for hepatic and/or splenic seeding of Candida. In our experience, hepatosplenic candidiasis (HSC) without documented candidemia often remains unrecognized. CASE PRESENTATIONS: We describe three cases of HSC without documented candidemia and the challenges in establishing the diagnosis and adequately treating this condition. The first patient had a history of SCT for treatment of breast cancer and was scheduled for hemihepatectomy for suspected liver metastasis...

Hepatic ischemia/reperfusion injury (IRI) and associated inflammation contributes to liver dysfunction and complications after liver surgery and transplantation. Mesenchymal stem cells (MSCs) have been reported to reduce hepatic IRI because of their reparative immunomodulatory effects in injured tissues. Recent studies have highlighted beneficial effects of extracellular vesicles from mesenchymal stem cells (MSC-EV) on tissue injury. The effects of systemically administered mouse bone marrow-derived MSC-EV were evaluated in an experimental murine model of hepatic IRI induced by cross-clamping the hepatic artery and portal vein for 90 minutes followed by reperfusion for periods of up to 6 hours...

Liver fibrosis is the consequence of hepatocyte injury that leads to the activation of hepatic stellate cells (HSC). The treatment of choice is Liver transplantation; however, it has many problems such as surgery-related complications, immunological rejection and high costs associated with the procedure. Stem cell-based therapy would be a potential alternative, so the aim of this study is to investigate the therapeutic potential of human umbilical cord mononuclear cells (MNC) and mouse bone marrow cells (BMC) against carbon tetrachloride (CCl4) induced liver fibrosis in mice and compare it with that of silymarin...

Crohn's disease, which mainly affects the gastrointestinal tract, is a refractory inflammatory disease that has clinical manifestations of abdominal pain, fever, bowel obstruction, and diarrhea with blood or mucus. Together, these symptoms can severely impair a patient's quality of life. Besides the common complication of intestinal obstruction, fistulas, particularly anorectal fistulas, are common in Crohn's disease patients. Since radical surgical cures can be difficult to achieve and relapse is common, Crohn's disease patients often seek other effective treatments in addition to surgery...

Bone is the most transplanted tissue human with 1 million procedures every year in Europe. Surgical interventions for bone repair are required for varied reasons such as trauma resulting non-union fractures, or diseases including osteoporosis or osteonecrosis. Autologous bone grafting is the gold standard in bone regeneration but it requires a second surgery with associated pain and complications, and is also limited by harvested bone quantity. Synthetic bone substitutes lack the osteoinductive properties to heal large bone defects...
