Data collection on apheresis activities in Italy throughout 2015 including techniques, clinical indications and adverse effects was performed by means of a SidEM model questionnaire (aggregate data). These data provided by 67 Apheresis Units from 17 Italian regions, albeit rough, are sufficiently informative, mainly in comparison with previous surveys on these statistics. PEx has been the most frequent technique for plasma removal/treatment (11787 procedures) followed by LDL-apheresis (927 procedures). ECP/photopheresis has been the most frequent cytapheresis procedure: 6,606 session, mainlyby using the off-line technique...

Soon, a virtual crossmatch shall replace the complement-dependent cytotoxicity (CDC) allocation crossmatch in the Eurotransplant region. To prevent positive CDC-crossmatches in the recipient centre, careful definition of unacceptable antigens is necessary. For highly sensitized patients, this is difficult by CDC alone. Assignment of all antibodies detected by sensitive assays, however, could prevent organ allocation. To assess the usefulness of the Luminex C1q-assay to prevent positive CDC-crossmatches, all CDC-crossmatches performed prior to deceased kidney transplantation in a 16-month-period were reviewed...

Recipients of solid organ transplants (SOT) have extensive diagnostic imaging (DI). The purpose of this study was to quantify this exposure. Children from northern Alberta with SOTs at Stollery Children's Hospital, Edmonton, Alberta January 1, 2006, to July 31, 2012, were included. Effective doses of radiation were estimated using published norms for DI performed post-transplant up to October 16, 2014. The 54 eligible children had 6215 DI studies (5628 plain films, 293 computerized tomography (CT) scans, 149 positron emission topography (PET) -CT scans, 47 nuclear medicine scans and 98 cardiac catheterizations)...

Diabetes is prevalent among solid organ transplant recipients and is universal among islet transplant recipients. While diabetes is often considered to result in an immune compromised state, the impact of chronic hyperglycemia on host alloimmunity is not clear. Potential immune modifying effects of obesity, autoimmunity, or diabetogenic agents like streptozotocin may confound understanding alloimmunity in experimental models of diabetes. Therefore, we sought to determine the role of chronic hyperglycemia due to insulinopenia on alloimmunity using the non-autoimmune, spontaneously diabetic H-2(b)-expressing C57BL/6 Ins2(Akita) mice (Akita)...

Disseminated acanthamoebiasis is a rare, often fatal, infection most commonly affecting immunocompromised patients. We report a case involving sinuses, skin, and bone in a 60-year-old woman 5 months after heart transplantation. She improved with a combination of flucytosine, fluconazole, miltefosine, and decreased immunosuppression. To our knowledge, this is the first case of successfully treated disseminated acanthamoebiasis in a heart transplant recipient and only the second successful use of miltefosine for this infection among solid organ transplant recipients...

BACKGROUND: As solid organ transplant (SOT) patients' survival improves, the number undergoing total hip (THA) and total knee arthroplasty (TKA) is increasing. Accordingly, the number of revision procedures in this higher-risk group is also increasing. The goals of this study were to identify the most common failure mechanisms, associated complications, clinical outcomes, and patient survivorship of SOT patients after revision THA or TKA. METHODS: A retrospective review identified 39 revision procedures (30 revision THAs and 9 revision TKAs) completed in 37 SOT patients between 2000 and 2013...

Diagnostic methods based on single nucleotide polymorphism (SNP) biomarkers are essential for the real adoption of personalized medicine. Allele specific amplification in a homogeneous format or combined to microarray hybridization are powerful approaches for SNP genotyping. However, primers must be properly selected to minimize cross-reactivity, dimer formation and nonspecific hybridization. This study presents a design workflow diagram for the selection of required oligonucleotides for multiplex assays. Based on thermodynamic restrictions, the oligonucleotide sets are chosen for a specific amplification of wild- and mutant-type templates...

Post-transplantation lymphoproliferative disorder is an aggressive complication of transplantation, most frequently of diffuse large B-cell lymphoma morphology and associated with Epstein-Barr virus (EBV) infection/reactivation. In this study the microenvironment of EBV(+) (n=23) and EBV(-) (n=9) post-transplant non-germinal center B-cell diffuse large B-cell lymphoma was characterized. Of EBV(+) cases somatic hypermutation analysis, gene expression profiling, and extensive phenotyping were performed. Our results demonstrated variable cytotoxic T-cell infiltration and significantly increased CD163(+) M2 macrophage infiltration in EBV(+) compared with EBV(-) post-transplant diffuse large B-cell lymphoma...

Solid tumors in adults constitute a heterogeneous group of malignancy originating from various organ systems. Solid tumors are not completely curable by chemotherapy, even though some subgroups are very chemo-sensitive. Recently, oncologists have focused on the use of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with reduced intensity conditioning (RIC) for the treatment of some refractory solid tumors. After the demonstration of allogeneic graft-versus-leukemia effect in patients with hematological malignancies who received allo-HSCT, investigators evaluated this effect in patients with refractory metastatic solid tumors...

While the costs to Medicare of solid organ transplants are varied and considerable, the total Medicare expenditure of $4.4 billion for solid organ transplant recipients in 2014 remained less than 1% of all Medicare expenditures. For patients covered by Medicare, the ratio of pre- to posttransplant cost of care varied widely by organ and within some organ categories by patient characteristics. This chapter reports pretransplant costs for all solid organ candidates covered by Medicare to allow investigators to further explore the relative cost of transplant compared with alternative management...

NCs occur commonly after solid organ transplantation and affect 15%-30% of liver transplant recipients. The aim of this retrospective study was to evaluate the type and incidence of neurologic events in pediatric patients following LT. Between May 2006 and June 2015, 242 patients (118 females, 124 males) requiring LT for different etiologies at the İnönü University Liver Transplantation Institute were included. The incidence, types, and risk factors of NCs that occurred following LT were evaluated retrospectively...

BACKGROUND: Lack of adherence to medication is a trigger of graft rejection in solid-organ transplant (SOT) recipients. OBJECTIVE: This exploratory study aimed to assess whether a biopsychosocial evaluation using the INTERMED instrument before transplantation could identify SOT recipients at risk of suboptimal post-transplantation adherence to immunosuppressant drugs. We hypothesized that complex patients (INTERMED>20) might have lower medication adherence than noncomplex patients (INTERMED≤20)...

Posttransplant lymphoproliferative disorder (PTLD) is a known complication of solid organ transplantation. Diffuse large B-cell lymphoma (DLBCL) is frequently seen in this setting. However, CD30+ DLBCL with sinusoidal pattern of involvement has not been reported in pediatric PTLD. We are reporting a 9-year-old female child presented with diffuse lymphadenopathy postheart transplantation. The pattern of involvement was suggestive of anaplastic large cell lymphoma, but the malignant cells were positive for B-cell markers and negative for anaplastic lymphoma kinase...

BACKGROUND: Proliferation signal inhibitors, such as sirolimus, are increasingly used in solid-organ transplantation. However, limited data exist on sirolimus-treated pediatric patients. We aimed to describe sirolimus use in pediatric heart transplant patients and test the hypothesis that sirolimus use is associated with improved outcomes. METHODS: A retrospective review and propensity-matched analysis of the Pediatric Heart Transplant Study database was performed on patients undergoing primary heart transplantation from 2004 to 2013 with at least 1 year of follow-up comparing patients treated vs not treated with sirolimus at 1 year after transplant...

PURPOSE: Solid organ transplants (SOT) continue to increase with recipients living longer than ever before. The lifelong immunosuppression in these patients also may place them at increased risk for postoperative complications. The efficacy of total hip arthroplasty (THA) in this patient population is undisputed but previous studies investigating the complication profiles in these patients often are underpowered to identify rare complications as well as make comparisons between individual organs...

Recognition of donor antigens by recipient T cells in secondary lymphoid organs initiates the adaptive inflammatory immune response leading to the rejection of allogeneic transplants. Allospecific T cells become activated through interaction of their T cell receptors with intact allogeneic major histocompatibility complex (MHC) molecules on donor cells (direct pathway) and/or donor peptides presented by self-MHC molecules on recipient antigen-presenting cells (APCs) (indirect pathway). In addition, recent studies show that alloreactive T cells can also be stimulated through recognition of allogeneic MHC molecules displayed on recipient APCs (MHC cross-dressing) after their transfer via cell-cell contact or through extracellular vesicles (semi-direct pathway)...
