Background: Invasive fungal infections remain a major cause of morbidity and mortality in transplant recipients. Moreover, Fungal Infective Endocarditis (FIE) is a rare infection that carries a higher mortality than bacterial IE in normal host, while in transplant recipients may be even higher. The purpose of this study was to systemically review all published cases of FIE in solid organ and allogeneic bone marrow transplant recipients, describe the epidemiology, microbiology, clinical characteristics, treatment and outcomes of these infections, and to identify risk factors for mortality by FIE.

The significance of human leukocyte antigen (HLA) matching and preformed donor-specific antibodies (DSAs) in liver transplantation remains unclear. The aim of this study was to analyze the presence of DSAs in a large cohort of 810 liver recipients undergoing liver transplant to determine the influence on acute (AR) or chronic liver rejection (CR), graft loss and allograft survival. DSAs were identified using complement dependent cytotoxicity crossmatch (CDC-CM) and multiplexed solid-phase-based flow cytometry assay (Luminex). Read More

Hematopoietic cell transplantation (HCT) is potentially curative for patients with hematologic disorders, but carries significant risks of infection-related morbidity and mortality. Infectious diseases are the second most common cause of death in HCT recipients, surpassed only by progression of underlying disease. Many infectious diseases are difficult to diagnose and treat, and may only be first identified by autopsy. Read More

Macrophages play a crucial role in the pathogenesis of chronic graft-versus-host disease (cGVHD). We hypothesized that galectin-3, Mac-2 binding protein (M2BP), or Wisteria floribunda agglutinin (WFA)+-M2BP, called M2BP glycan isomer (M2BPGi), might contribute to macrophage activation, and fibrosis would be associated with cGVHD and nonrelapse mortality (NRM) in hematopoietic stem cell transplant (HSCT) recipients. Patients who underwent their first allogeneic HSCT and survived for >180 days without relapse were included. Read More

Invasive aspergillosis (IA) incidence is increasing in several countries like France, and numerous cases are indeed missed and still only diagnosed at autopsy as evidenced by recently published data. Such missed diagnoses are obviously encountered when appropriate diagnostic tools are not available especially in low resource areas or when biologists have not been trained enough in medical mycology (i.e. Read More

BACKGROUND The aim of this study was to investigate the feasibility of laparoscopic combined para-orthotopic pancreas and orthotopic kidney transplantation in a pig model. MATERIAL AND METHODS Twelve white female pigs, (4-5 months old, weight range 40-45 kg) were used as donors and recipients, and 6 laparoscopic-combined pancreas and kidney transplantations were performed. After bilateral nephrectomy, the pancreatic artery and vein were anastomosed to the right renal artery and vein, respectively, and the pancreatic fluid was diverted to the duodenum or jejunum.

Reconstitution of hepatocytes by hematopoietic stem cells-a phenomenon which occurs in rodents under highly selective conditions-results from infrequent fusion between incoming myelomonocytes and host hepatocytes, with subsequent proliferation. Human hematopoietic stem cell transplant recipients have been little studied, with some support for transdifferentiation (direct differentiation). We studied routinely obtained autopsy liver tissue of four female hematopoietic cell transplant recipients with male donors, using a highly specific conjoint immunohistochemistry in situ hybridization light microscopic technique.

Granulomatous amebic encephalitis is a rare necrotizing infection of the CNS that occurs most commonly in immunocompromised individuals and is usually fatal. It is difficult to diagnose as the clinical symptoms and radiographic findings are often mistaken for other bacterial, viral, fungal, or protozoan infections. Herein, we present the case of a 69-year-old heart transplant recipient who suffered fulminant neurological decline ∼5 months after transplant. Read More

Autopsy may confirm clinical diagnoses or identify conditions that were not suspected prior to a patient's death. Previous studies evaluating the utility of autopsy in hematopoietic stem cell transplant (HSCT) recipients yielded conflicting results. We conducted a retrospective cohort study of children (<18 years of age) undergoing allogeneic HSCT at Duke University who died of any cause between January 1, 1995, and December 31, 2016. Read More

We describe a case of a patient treated for relapse of chronic lymphoblastic leukaemia 6 years after HSCT.

Miliary tuberculosis is a lethal form of disseminated tuberculosis (TB), deriving its name from the millet-seed-sized granulomas in multiple organs. As TB still remains a leading cause of morbidity and mortality in India, its disseminated forms need to be diagnosed early to ensure more aggressive treatment at the earliest possible time. However, a considerable number of cases are missed ante-mortem. Read More

Background: In the past decade, C4d has emerged as a potential marker for antibody-mediated rejection (AMR); however, evidence on its use as a prognostic tool has been controversial. Although the International Society for Heart and Lung Transplantation guideline recommends early routine surveillance of C4d in heart transplantation, there is no consensus on its value in the pathologic assessment of AMR. Herein we present a correlation analysis of C4d immunoreactivity in endomyocardial biopsies with clinical cardiac dysfunction, cellular rejection, human leukocyte antigen (HLA) status, cardiac allograft vasculopathy (CAV) and death.
