Solid-organ transplant recipients are at higher risk of developing Kaposi sarcoma, which is a multicentric vascular neoplasm of lymphatic endothelium-derived cells. Reducing doses of immunosuppressive drugs and switching from calcineurin inhibitors to the mammalian target of rapamycin inhibitor rapamycin have been suggested as an effective first-line treatment modality in most patients. Herein, we report a 64-year-old renal transplant recipient who developed multiple cutaneous and visceral Kaposi sarcoma lesions 2 months after transplant...

Invasive fusariosis in solid organ transplant is uncommon and usually presents as localized infection with favorable outcomes compared to hematologic malignancies or bone marrow transplants. We report the first case of Fusarium osteomyelitis in a patient following multi-visceral transplant and review Fusarium in organ transplant recipients and Fusarium bone and joint infections. Our case underscores the importance of early recognition and multidisciplinary approach to treatment and highlights potential failure to eradicate with amphotericin B monotherapy...

BACKGROUND: Visceral disseminated varicella zoster viral (VZV) infection is a rare but severe complication with a high mortality rate in immunosuppressed individuals, and an increased susceptibility to VZV has been reported in kidney transplant recipients who are treated with mycophenolate mofetil (MMF). In Japan, MMF is currently approved for patients with lupus nephritis (LN) and data to indicate its optimal dosage are still insufficient. CASE PRESENTATION: A 46-year-old Japanese woman with rheumatoid arthritis was diagnosed as having systemic lupus erythematosus (SLE) and LN class III (A/C)...

Intestine failure-associated liver disease (IFALD) is widely recognized as a lethal complication of long-term parenteral nutrition. The pathophysiology of IFALD is poorly understood but appears to be multifactorial and related to the inflammatory state in the patient with intestinal failure (IF). Visceral transplantation for IFALD includes variants of intestine, liver, or combined liver and intestine transplantation. Graft selection for an individual patient depends on the etiology of intestinal failure, abdominal and vascular anatomy, severity of IFALD, and potential for intestinal rehabilitation...

Sarcopenia, the loss of muscle mass, has been identified as a potential risk factor for adverse outcomes in hematopoietic cell transplantation (HCT) recipients. However, much remains unknown about change in body composition following HCT. We retrospectively evaluated computed tomography (CT) imaging from 315 lymphoma patients undergoing HCT at our institution between 2000 and 2014. Cross-sectional area of lean muscle, subcutaneous adipose tissue and visceral adipose tissue were measured on CT at the level of the third lumbar vertebral body prior to HCT, 1-year post-HCT, and 2...

Brown adipose tissue (BAT) has been found as an endocrine organ that maintains metabolic homeostasis; however, the effects on atherosclerosis remain undefined. Here, we investigated the effect of experimental BAT transplantation on atherosclerosis. Interscapular BAT was dissected from wild-type mice and transplanted into the visceral cavity of 12-week-old apoE-/- mice. Oil-red O staining of whole aortas after 3 months of a high-cholesterol diet showed a significant decrease in atherosclerotic lesion area in BAT-transplanted mice by 32% compared with the sham control mice...

BACKGROUND: The significance of pre-operative body composition has recently attracted much attention in various diseases. However, cut-off values for these parameters remain undetermined, and these factors are not currently included in selection criteria for recipients of living donor liver transplantation (LDLT). METHODS: Using computed tomography of 657 donors for LDLT, skeletal muscle mass, muscle quality, and visceral adiposity were evaluated by using skeletal muscle mass index (SMI), intramuscular adipose tissue content (IMAC), and visceral-to-subcutaneous adipose tissue area ratio (VSR)...

We report the first application of ultra-deep sequencing (UDS) to varicella-zoster virus (VZV) genotypic antiviral testing in a case of acyclovir-resistant VZV infection initially detected by Sanger sequencing within a deeply immunocompromised heart transplant recipient. As added-value compared to Sanger analysis, UDS revealed complex dynamics of viral population under antiviral pressure. Varicella-zoster virus (VZV) is a ubiquitous human herpesvirus affecting populations worldwide. VZV is commonly acquired in youth whose primary infection usually manifests as benign varicella (chickenpox)...

Chronic rejection affects the long-term survival of all solid organ transplants and, among intestinal allografts, occurs in up to 10% of the recipients. The insidious clinical evolution of the chronic allograft enteropathy, the absence of noninvasive biomarkers, and the late endoscopic findings delay its diagnosis. No pharmacological approach has been proven effective, and allograft removal nowadays still represents the only available therapy. The inclusion of the liver in the visceral allograft appears to be the only intervention affecting the development of chronic rejection, as revealed by large-center studies and registry reports...

INTRODUCTION: Contamination of the preservation solution may contribute to septic complications that can occur after transplantation and cause higher morbidity and mortality among recipients. The aim of this study was to determine potential donor-related predictors of positive microbiological findings in the preservation solution. DESIGN: We retrospectively studied 16 donor parameters on data from our center for microbiological findings in the preservation solution used in solid-organ recovery...

BACKGROUND: The profound inflammatory response associated with brain death is frequently cited as the reason organs procured from brain dead donors are associated with worse graft function. The intestine releases inflammatory mediators in other types of shock, but its role is brain death has not been well-studied. Direct peritoneal resuscitation (DPR) improves visceral organ blood flow and reduces inflammation after hemorrhagic shock. We hypothesized that use of DPR would maintain intestinal integrity and reduce circulating inflammatory mediators after brain death...

INTRODUCTION: Portal vein thrombosis (PVT) poses an extremely difficult problem in cirrhotic patients who are in need of a liver transplant. The prevalence of PVT in patients with cirrhosis ranges from 0.6% to 26% Nery et al. (2015) [1]. The presence of PVT is associated with more technically difficult liver transplant and in certain cases can be a contraindication to liver transplant. The only option for these patients with extensive PVT would be a multi-visceral transplant, the later unfortunately has a much higher morbidity and mortality compared to liver only transplant Smith et al...

The evolution of multi-visceral and isolated intestinal transplant techniques over the last 3 decades has highlighted the technical challenges related to the closure of the abdomen at the end of the procedure. Two key factors that contribute to this challenge include: (1) Volume/edema of donor graft; and (2) loss of abdominal domain in the recipient. Not being able to close the abdominal wall leads to a variety of complications and morbidity that range from complex ventral hernias to bowel perforation. At the end of the 90's this challenge was overcome by graft reduction during the donor operation or bench table procedure (especially reducing liver and small intestine), as well as techniques to increase the volume of abdominal cavity by pre-operative expansion devices...

OBJECTIVE: Obesity is a risk factor for non-alcoholic steatohepatitis (NASH). This risk has been attributed to visceral adipose tissue (vAT) expansion associated with increased proinflammatory mediators. Accumulation of CD11c+ proinflammatory adipose tissue macrophages (ATM) is an important driver of vAT inflammation. We investigated the role of ATMs in hepatic inflammation during NASH development. DESIGN: vAT isolated from lean, obese or ATM-depleted (using clodronate liposomes) obese mice was transplanted to lean ldlr-/- acceptor mice...

BACKGROUND: Alterations in body composition (BC) as loss of fat and muscle mass (sarcopenia) are associated with poor outcome in alcoholic cirrhosis (ALC). Prevalence of sarcopenia depends upon the method of assessment. Computed Tomography (CT) is a gold standard tool for assessing BC. AIM: To characterize BC and define sarcopenia in ALC patients using CT. METHODS: Single slice CT images at L3 vertebrae of healthy controls (HC) - organ transplant donors and ALC patients were analysed to give cross-sectional area of five skeletal muscles normalized for height -skeletal muscle index (SMI; cm(2) /m(2) ), area of subcutaneous (SAT;cm(2) ) and visceral adipose tissue (VAT;cm(2) )...

Kaposi sarcoma is one of the most common malignancies seen during the posttransplant period, and it usually manifests in its cutaneous form. Renal transplant involvement is rare, whereas renal transplant parenchymal involvement causing transplant dysfunction is exceptionally rare. We report a case of visceral Kaposi sarcoma that led to renal transplant failure due to neoplastic infiltration of the renal allograft.
