Refractory celiac disease (RCD) is a rare condition in which a known celiac patient, usually an adult, suffers from persistence or recurrence of gluten-related symptomatology, laboratory abnormalities, and inflammatory enteropathy despite following an optimal dietary therapy with gluten-free diet (GFD). Arbitrarily, a duration of at least 12 months of GFD has been recommended prior to establishing such a diagnosis. Furthermore, exclusion of the other possible causes of non-celiac villous atrophy, particularly enter [...]

Many studies have demonstrated that HLA-DR, HLA-DQ and HLA-DP matching at the eplet level reduces allograft rejection and improves transplant outcome. Such studies have examined the eplet effect for the individual class II loci, but until now little attention has been given to so-called interlocus class II eplets shared between HLA-DR, HLA-DQ and/or HLA-DP alleles. This report summarizes current information about antibody-verified interlocus class II eplets. It describes a structural modeling method to determine po [...]

Invasive fungal disease (IFD) is a significant contributor to morbidity and mortality in pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). Early detection and timely initiation of antifungal therapy is important for improved outcome, but diagnosis remains difficult, especially when relying on conventional microbiology methods such as culture and microscopy. Data on the use of fungal biomarkers for screening and diagnosis of IFD in HSCT pediatric patients are limited, precluding the devel [...]

Immunosuppressive therapy in renal transplantation is divided into two phases as induction and maintenance therapy. Induction therapy is an intense immunosuppressive therapy administered at the time of kidney transplantation to reduce the risk of acute allograft rejection. In general, induction immunosuppressive strategies utilized by kidney transplant centers fall in one of the two categories. One approach relies upon high doses of conventional immunosuppressive agents, while the other uses antibodies directed aga [...]

Donation after circulatory death (DCD) is an increasingly used resource to alleviate chronic renal graft shortages. Organs from donors with progressively increased creatinine levels due to acute kidney injury are used, but the effects of this condition on kidney transplantation are still unclear. Ex-situ machine perfusion is emerging as a potential tool to preserve and resuscitate vulnerable grafts. We report a case of DCD kidneys discarded due to severe acute kidney injury with favorable histological Karpinski sco [...]

Background: Substantial evidence has established links between air pollution and increased risks of overall morbidity and mortality, especially for respiratory and cardiovascular diseases. However, little research has explored these relationships among highly sensitive populations, such as renal transplant recipients. Despite the improvement in quality of life after renal transplantation, cardiovascular diseases (CVD) are major causes of graft loss and mortality. The present study was designed to assess the associa [...]

Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are idiopathic and progressive autoimmune hepatobiliary disorders that lead to liver failure and a need for liver transplantation in a proportion of individuals with poorly controlled disease. It is currently thought that an environmental agent triggers disease in a genetically susceptible host and to date, xenobiotics, bacteria and a human betaretrovirus have all been linked with PBC. However, there is no consensus on which agents predomina [...]

Antibody-mediated rejection represents a significant barrier to favorable long-term outcomes after kidney transplantation and remains the most common cause of allograft failure. Therapeutic apheresis techniques are commonly used, in combination with other treatments such as immunosuppressive drugs, in the pre-transplant and post-transplant protocols for the prevention and treatment of antibody-mediated injury. The rationale is to remove the donor-specific antibodies and the other inflammatory mediators, which inclu [...]

Objective: The purpose of this study was to evaluate the common locations of perihepatic fluid collections after liver transplantation, assess their complexity, and understand their natural history and clinical significance. Materials and Methods: A retrospective analysis of 189 postoperative orthotopic liver transplant patients with a mean age 49.6 years was performed using serial CT or MRI to characterize perihepatic fluid collections. Location, size, complexity of the collections, and clinical course were evalua [...]
