Matthew J Damasiewicz, Peter R Ebeling
The management of post-transplantation bone disease is a complex problem that remains under-appreciated in clinical practice. In these patients, pre-existing metabolic bone disorder is further impacted by the use of immunosuppressive medications (glucocorticoids and calcineurin-inhibitors), variable post-transplantation renal allograft function and post-transplantation diabetes mellitus. The treatment of post-transplantation bone loss should begin pre-transplantation. All patients active on transplant waiting lists should be screened for bone disease...

AIM: To develop a locally adapted, patient-focused transition-program, we evaluated the perceptions of adult and adolescent patients and parents regarding transition-programs and transfer. METHODS: We evaluated these perceptions by analyzing the responses of pre-transfer adolescents (n = 57), their parents (n = 57) and post-transfer adults (n = 138) from a cohort of pediatric-liver-transplant-patients using a self-designed questionnaire. Furthermore, we compared a responder group with a non-responder group as well as the provided answers with baseline characteristics and clinical outcomes to exclude selection bias, characterize high-risk patients for non-adherence and test for gender differences...

REVIEW
Mariana Ciocchini, Jorge Arbelbide, Carlos G Musso
Monoclonal gammopathy of renal significance (MGRS) is a new nosological group of entities (meta-entity) defined in 2012, whose pathogenesis depends on monoclonal immunoglobulins (Ig) secreted by low-grade lymphoproliferative disorders, which belong to M-protein-related diseases. Renal damage is the result of monoclonal Ig deposit or its activity as autoantibodies, which can compromise any nephronal area. MGRS does not include kidney diseases produced by high-grade lymphoproliferative disorders as well as those whose pathogenesis are independent of monoclonal Ig (such as drug toxicity or metabolic disorders)...

Despite careful donor screening, unexpected donor-derived infections continue to occur in organ transplant recipients (OTRs). Lymphocytic choriomeningitis virus (LCMV) is one such transplant-transmitted infection that in previous reports has resulted in a high mortality among the affected OTRs. We report a LCMV case cluster that occurred 3 weeks post-transplant in three OTRs who received allografts from a common organ donor in March 2013. Following confirmation of LCMV infection at Centers for Disease Control and Prevention, immunosuppression was promptly reduced and ribavirin and/or intravenous immunoglobulin therapy were initiated in OTRs...

BACKGROUND: Mesenchymal stem cells (MSCs) show therapeutic efficacy in many different age-related degenerative diseases, including Alzheimer's disease. Very little is currently known about whether or not aging impacts the transplantation efficiency of MSCs. METHODS: In this study, we investigated the distribution of intravenously transplanted syngeneic MSCs derived from young and aged mice into young, aged, and transgenic APP/PS1 Alzheimer's disease mice. MSCs from male donors were transplanted into female mice and their distribution pattern was monitored by PCR using Y-chromosome specific probes...

Background Lupus nephritis (LN) is one of the most frequent complications of SLE and occurs in up to 50% of cases depending on the studied population. Of these, approximately 20% progress to end-stage renal disease (ESRD), with the treatment of choice being a kidney transplant. Objective The objective of this study was to describe the clinical outcome of patients transplanted due to LN, compared with patients transplanted for other causes, in a Latin American population from the Fundación Valle del Lili in Cali, Colombia...

BACKGROUND: Hemolytic uremic syndrome (HUS) can be triggered by Shiga toxin producing Escherichia coli (STEC) infection or it can be defined as atypical HUS (aHUS) if it is related to uncontrolled complement activation. aHUS is characterized by a high incidence of recurrence after kidney transplantation, and it can also occur de novo in transplant recipients. Eculizumab is used both to prevent and to treat aHUS following kidney transplantation. In this paper, we report our centre experience and we present 4 cases of HUS in patients who underwent kidney transplantation...

Calcineurin inhibitors are powerful immunosuppressants that revolutionized organ transplantation. However, non-immune effects of the calcineurin inhibitor, such as cyclosporine A (CsA), have significantly hindered their use. Specifically, nephrotoxicity, which is associated with tubulointerstitial fibrosis, inflammation, and podocyte damage, affects up to half of all transplant patients. Calcineurin is involved in many aspects of kidney development and function; therefore, mechanisms of CsA-induced nephrotoxicity are complex and not yet fully understood...

PURPOSE: To evaluate whether ultrasmall superparamagnetic iron oxide nanoparticle (USPIO)-enhanced magnetic resonance imaging (MRI) can detect allograft rejection in pediatric kidney transplant patients. PROCEDURES: The USPIO ferumoxytol has a long blood half-life and is phagocytosed by macrophages. In an IRB-approved single-center prospective clinical trial, 26 pediatric patients and adolescents (age 10-26 years) with acute allograft rejection (n = 5), non-rejecting allografts (n = 13), and normal native kidneys (n = 8) underwent multi-echo T2* fast spoiled gradient-echo (FSPGR) MRI after intravenous injection (p...

BACKGROUND There are several genes and genetic loci affecting telomere length, including hTERT gene and BICD1 gene as well as polymorphisms within chromosome 18. It has been demonstrated that the age of the donor is a negative factor associated with long-term kidney allograft function, and that post-transplant complications accelerate transplanted organ aging, thus contributing to estimated glomerular filtration rate (eGFR) decreases. The aim of this study was a joint assessment of donors' and recipients' hTERT and BICD1 genes as well as chromosome 18 polymorphisms with regard to early kidney transplantation outcomes...

Magnusiomyces capitatus (previously known as Geotrichum capitatum or Blastoschizomyces capitatus or Trichosporon capitatum) is a rare cause of fungal infection in immunocompromised patients. Most of these cases (87%) have been reported from the Mediterranean region, as it is extremely rare to recognize it in other regions. Here we report a first case of disseminated M. capitatus infection in Slovakia. The patient - 19 year old woman with myelodysplastic syndrome was diagnosed with M. capitatus fungemia after allogeneic stem cell transplantation...

There is limited information on kidney transplant recipients with end-stage renal disease (ESRD) due to scleroderma. We conducted an observational study on kidney transplant recipients with ESRD due to scleroderma who received kidney transplant at our center between 01/1994 and 06/2013. During the study period, there were 10 kidney transplant recipients, all of whom were Caucasian females. Seven of them were living-donor kidney transplant recipients, and the mean age at time of transplant was 56.6 ± 11.99 years...

OBJECTIVE: The aim of this study was to compare the outcomes of simultaneous and delayed implantation of kidney grafts in combined liver-kidney transplantation (CLKT). BACKGROUND DATA: Delayed function of the renal graft (DGF), which can result from hypotension and pressor use related to the liver transplantation (LT), may cause worse outcomes in CLKT. METHODS: A total of 130 CLKTs were performed at Indiana University between 2002 and 2015 and studied in an observational cohort study...

Solid organ transplant recipients have an elevated incidence of thyroid cancer. We evaluated a wide range of potential risk factors in a cohort of 229,300 U.S. solid organ transplant recipients linked with 15 stage/regional cancer registries (1987-2012). Incidence rate ratios (IRRs) were adjusted for age, sex, race/ethnicity, transplanted organ, year of transplant, and time since transplant. Hazards ratios (HRs) for death and/or graft failure were adjusted for age, sex, race/ethnicity, transplanted organ, and year of transplant...
