This study describes the risk of thrombotic and hemorrhagic complications, both intraoperatively, and up to 1-month following visceral transplantation. Data from 48 adult visceral transplants performed between 2010-2017 were retrospectively studied (32 multivisceral (MVTx); 10 isolated intestine; 6 modified-MVTx). Intraoperatively, intracardiac thrombosis (ICT)/pulmonary embolism (PE) occurred in 25%, 0% and 0% of MVTx, isolated intestine and modified MVTx, respectively, and was associated with 50% (4/8) mortality...

BACKGROUND: Pleuroparenchymal fibroelastosis (PPFE) is a very rare interstitial lung disease (ILD) characterized by progressive fibrotic lesions of the visceral pleura and the sub-pleural parenchyma, affecting predominantly the upper lobes. PPFE may occur in different contextes like bone marrow or lung transplantations, but also in the context of telomeropathy with mutations of telomerase reverse transcriptase (TERT), telomerase RNA component (TERC) or regulator of telomere elongation helicase 1 (RTEL1) genes...

Immunosuppression contributes significantly to the caseload of visceral leishmaniasis (VL). HIV coinfection, solid organ transplantation, malnutrition, and helminth infections are the most important immunosuppression-related factors. This review briefly describes the challenges of these associations. East Africa and the Indian subcontinent are the places where HIV imposes the highest burden in VL. In the highlands of Northern Ethiopia, migrant rural workers are at a greater risk of coinfection and malnutrition, while in India, HIV reduces the sustainability of a successful elimination programme...

The increasing number of transplants performed worldwide and the growing global mobility with migration and travel to and from developing countries and tropical areas are bringing new challenges for the management of transplant infectious diseases, previously less commonly seen, such as Leishmaniasis. However, in this scenario there is a lack of information and the current knowledge is based on a few studies. The selection of the most appropriate treatment depends on various factors, such as patient profile, Leishmania species, disease extent, drug availability, concomitant infections and previous treatments...

The successful development of multivisceral and composite visceral transplantation is among the milestones in the recent history of human organ transplantation. All types of gastrointestinal transplantation have evolved to be the standard of care for patients with gut failure and complex abdominal pathologic conditions. The outcome has markedly improved over the last 3 decades owing to technical innovation, novel immunosuppression, and better postoperative care. Recent data documented significant improvement in the long-term therapeutic indices of all types of visceral transplantation close to that achieved with thoracic and solid abdominal organs...

CD200 is a widely expressed cell surface glycoprotein that inhibits excessive inflammation in autoimmunity, transplantation, and viral infections. We previously observed that visceral metastasis of highly aggressive and inflammatory 4THM breast carcinoma cells was markedly decreased in CD200 transgenic mice. The goal of this study was to determine whether exogenous exposure to CD200fc mimics the effects of endogenously over expressed CD200. Female BALB/c mice were injected with CD200fc two times a week for five times...

BACKGROUND & AIMS: Two main body compartments, skeletal muscle and adipose tissue, exhibit independent functions. We aimed to explore the prognostic significance of skeletal muscle, visceral and subcutaneous adipose tissue, according to sex, in patients with cirrhosis assessed for liver transplantation (LT). METHODS: CT images taken at the 3rd. lumbar vertebra from 677 patients were quantified for three body composition indexes (cm2 /m2 ), visceral adipose tissue index (VATI), subcutaneous adipose tissue index (SATI), and skeletal muscle index (SMI)...

The ability of human cytomegalovirus (HCMV) to reactivate from latent infection of hematopoietic progenitor cells (HPCs) is intimately linked to cellular differentiation. HCMV encodes UL7 that our group has shown is secreted from infected cells and induces angiogenesis. In this study, we show that UL7 is a ligand for Fms-like tyrosine kinase 3 receptor (Flt-3R), a well-known critical factor in HPC differentiation. We observed that UL7 directly binds Flt-3R and induces downstream signaling cascades, including phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) pathways...

Background: Alexithymia is a multifaceted personality construct that represents a deficit in the cognitive processing of emotions and is currently understood to be related to a variety of medical and psychiatric conditions. The present review aims to investigate the relationship of alexithymia with gastrointestinal (GI) disorders as functional gastrointestinal disorders (FGID, as irritable bowel syndrome (IBS) and functional dyspepsia) and inflammatory bowel disease (IBD) [ulcerative colitis (UC) and Crohn's disease (CD)] and liver diseases as chronic hepatitis C (CHC), cirrhosis, and liver transplantation...

Chronic pancreatitis (CP) is a severely disabling disorder with potential detrimental effects on quality of life, gut function, and glucose homeostasis. Disease progression often results in irreversible morphological and functional abnormalities with development of chronic pain, mechanical obstruction, and pancreatic insufficiency. Along with comprehensive medical management, the concept of total pancreatectomy and islet autotransplantation (TP-AIT) was introduced forty years ago for patients with intractable pain and preserved beta-cell function...

The domestic dog is considered the main reservoir of visceral leishmaniasis (VL) in urban areas, but the identification of cats infected by Leishmania suggests the possibility of these animals also acting as reservoirs. The incrimination of a species as reservoir requires the accumulation of epidemiological evidence on the co-occurrence between such species and the infection in question. This is a systematic review of epidemiological studies evaluating the association between exposure to cats and occurrence of VL in humans (HVL) or dogs (CVL)...

Pseudoaneurysm (PA) of the cystic artery is rare. Most of the reported cases are iatrogenic and develop secondary to liver biopsy, laparoscopic cholecystectomy, ERCP, and liver transplant. Other reported causes include trauma, malignancy, arteriovenous malformations, and inflammation in the hepatobiliary and pancreatic system. Cystic artery psuedoaneurysm is usually asymptomatic but may also present as vague abdominal pain, intra-abdominal mass, and hemobilia. In the event of rupture, it may present as a catastrophic intra-peritoneal bleeding with hemorrhagic shock...

Visceral leishmaniasis is a disease caused by the protozoan Leishmania and is transmitted by Lutzomyia longipalpis (sand fly). It is an endemic parasitic infection in numerous areas around the Mediterranean basin. Though immunocompetent patients may not develop the disease, in transplant recipients the use of corticoids and intensified immunosuppressants to prevent graft rejection may accelerate the disease, causing severe damage to the liver, spleen, and hematopoietic system. We report 2 cases of visceral leishmaniasis with an atypical presentation in transplant recipients...

Bone marrow transplantation (BMT) offers curative potential for patients with high-risk hematologic malignancies, but the post-transplantation period is characterized by profound immunodeficiency. Recent studies indicate that the intestinal microbiota not only regulates mucosal immunity, but can also contribute to systemic immunity and hematopoiesis. Using antibiotic-mediated microbiota depletion in a syngeneic BMT mouse model, here we describe a role for the intestinal flora in hematopoietic recovery after BMT...

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)...

Intestinal failure (IF)-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 IF. Visceral transplant for IFALD includes variants of intestine, liver, or combined liver-intestine allografts. Graft selection for an individual patient depends on the etiology of IF, 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 areas of lean muscle, subcutaneous adipose tissue, and visceral adipose tissue were measured on CT at the level of the third lumbar vertebral body before HCT, 1-year post-HCT, and 2...
