BACKGROUND: The incidence of visceral leishmaniasis (VL) after solid organ transplantation (SOT) is increasing. The optimal therapy for post-transplant VL remains unclear, as relapses after liposomal amphotericin B (L-AmB) are common. Miltefosine has been shown to be effective for treating VL in immunocompetent patients, although data in the specific population of SOT recipients are lacking. METHODS: In the setting of an outbreak of leishmaniasis occurring in Southwest Madrid, we reviewed our experience in 6 SOT recipients with persistent or relapsing VL who received a 28-day course of miltefosine (2...

Visceral adipose tissue is a primary site of chronic inflammation in obesity and may contribute to systemic inflammation and development of atherosclerotic vascular disease. Few studies identify molecular mechanisms and secretory pathways which mediate this process. In this edition of Clinical Science, Kwok et al. utilize a transgenic mouse in which dominant-negative c-Jun NH2 terminal kinase (dnJNK) expression is restricted to adipose tissue to implicate JNK-driven expression of adipocyte fatty acid binding protein (A-FABP) in visceral adipose tissue as a key secretory pathway to exacerbate development of atherosclerosis in ApoE-/- mice...

BACKGROUND: Gender differences in medicine are gaining in importance. In transplant surgery, not only the patient's gender but also that of the donor play an important role in the outcome of transplantation due to sociocultural and genetic factors. METHODS: This review article gives an overview of the latest investigations into gender-related influences in the field of visceral transplantation. For this purpose, a systematic review of the literature was performed...

Organ transplantation in patients with prior malignancy increases the risk of tumor recurrence post-transplantation due to immunosuppression. Only two cases of liver transplantation have so far been reported in children with hepatic metastases from pancreatoblastoma, a rare malignant neoplasm originating from the epithelial exocrine cells of the pancreas. Herein, we describe a case of a successful multi-visceral transplant in a man with intestinal failure after surgical resection of pancreatoblastoma.

BACKGROUND: A few studies have investigated the role of adiponectin fraction for cardiovascular disease (CVD) in RTx recipients. SUBJECTS AND METHODS: We studied 57 adult subjects (39 males, 18 females; 10 cadaveric donors) with at least three years of allograft survival (median 251 months). We examined clinical backgrounds such as treated drugs, blood pressure (BP, mmHg), body mass index (BMI), and blood chemistry including cholesterol (total, LDL-C, HDL-C), glucose, glycated hemoglobin (HbA1c), and serum high and low-molecular-weight (HMW/LMW) ADPN fractions with regard to the associations of the visceral and subcutaneous fat areas on CT scan...

Nephrotic syndrome (NS) is a common pediatric kidney disease and is defined as massive proteinuria, hypoalbuminemia, and edema. Dysfunction of the glomerular filtration barrier, which is made up of endothelial cells, glomerular basement membrane, and visceral epithelial cells known as podocytes, is evident in children with NS. While most children have steroid-responsive nephrotic syndrome (SSNS), approximately 20% have steroid-resistant nephrotic syndrome (SRNS) and are at risk for progressive kidney dysfunction...

Caloric restriction (CR) extends lifespan from yeast to mammals, delays onset of age-associated diseases, and improves metabolic health. We show that CR stimulates development of functional beige fat within the subcutaneous and visceral adipose tissue, contributing to decreased white fat and adipocyte size in lean C57BL/6 and BALB/c mice kept at room temperature or at thermoneutrality and in obese leptin-deficient mice. These metabolic changes are mediated by increased eosinophil infiltration, type 2 cytokine signaling, and M2 macrophage polarization in fat of CR animals...

BACKGROUND: The paradigm for donation after cardiac death subjects donor organs to ischemic injury. A dual-chamber organ perfusion stent would maintain organ perfusion without affecting natural cardiac death. A center lumen allows uninterrupted cardiac blood flow, while an external chamber delivers oxygenated blood to the visceral vessels. METHODS: A prototype organ perfusion stent was constructed from commercial stents. In a porcine model, the organ perfusion stent was deployed, followed by a simulated agonal period...

Both atherosclerosis and obesity, an independent atherosclerotic risk factor, are associated with enhanced systemic inflammation. Obesity is also characterized by increased adipose tissue inflammation. However, the molecular mechanism underlying the accelerated atherosclerosis in obesity remains unclear. In obesity, activation of c-Jun N-terminal kinase (JNK) contributes to adipose tissue inflammation. The present study investigated whether the suppression of fat inflammation through adipose-specific JNK inactivation could protect against atherosclerosis in mice...

We report the case of a lung transplant recipient in whom the diagnosis of visceral leishmaniasis (VL) was made by detection of parasites in a peripheral blood smear when the parasite load already reached 8.9 × 10(3) parasites/mL. We demonstrated that the VL diagnosis could have been done months before the development of symptoms by the use of Leishmania-specific real-time polymerase chain reaction (PCR), suggesting the role of preemptive PCR-based diagnosis in transplant recipients at risk for VL.

Visceral disseminated varicella zoster virus (VZV) disease has a high mortality rate, and occurs in immunocompromised hosts, mostly subsequent to allogeneic stem cell transplantation. Only a few cases of this disease that onset during conventional chemotherapy in patients with lymphoma have been reported. The present study reports the cases of 3 patients with disseminated and visceral VZV infection undergoing treatment for follicular lymphoma, diffuse large B-cell lymphoma and peripheral T-cell lymphoma, not otherwise specified...

BACKGROUND: Photochemotherapy may be used to treat cutaneous graft-versus-host disease (GvHD). Animal models show that in the days after photochemotherapy and antigen provocation, cells with an antigen-specific suppressive phenotype are elicited in the lymphoid organs. In GvHD, host antigens are present not only in the skin treated by photochemotherapy but also in the visceral tissues. OBJECTIVE: The aim of this paper was to evaluate the effect on visceral acute GvHD (aGvHD) of photochemotherapy of the skin...

Sclerodermatous GVHD (Scl-GVHD), a frequent complication of allogeneic hematopoietic stem cell graft, shares many features with systemic sclerosis, such as production of autoantibodies and fibrosis of skin and inner organs. Recent reports on the implication of STAT3 and of Wnt/β-catenin in fibrosis have prompted us to investigate the effects of the inhibition of both signaling pathways in a mouse model of Scl-GVHD, using niclosamide an anthelmintic drug with well-defined safety profile. Scl-GVHD was induced in BALB/c mice by B10...

Obesity is a risk factor for primary graft dysfunction, a form of lung injury resulting from ischemia reperfusion after lung transplantation, but the impact of ischemia reperfusion on adipose tissue is unknown. We evaluated differential gene expression in thoracic visceral adipose tissue (VAT) before and after lung reperfusion. Total RNA was isolated from thoracic VAT sampled from 6 subjects enrolled in the Lung Transplant Body Composition study before and after allograft reperfusion and quantified using the Human Gene 2...

Hepatic VOD (veno-occlusive disease) is a serious complication of HSCT (hematopoietic stem cell transplantation) and has historically been associated with high mortality. This obstruction to hepatic flow often results in fluid collections in the peritoneal and pleural cavities. Catheter placement to drain ascites or pleural fluid may reduce intra-abdominal hypertension and/or improve respiratory parameters. The safety of these interventions among critically ill, immunocompromised children is unknown. Among 32 HSCT recipients (2000-2012) with severe VOD, we assessed the primary outcome of procedural complication from peritoneal drain placement...
