Hepatitis B virus (HBV) infection is frequent among patients with chronic kidney disease (CKD). HBV reactivation after kidney transplant (KT) is more common in patients with HBsAg+; however, it can also occur in previously infected individuals, particularly those with HBsAg negative and total antiHBc positive (HBsAg-/antiHBcT+). However, reactivation in this population has scarce and conflicting data. This study aimed to assess the reactivation risk in KT recipients with previous HBV infection (antiHBcT+). A retros [...]

Race, while a social construct, has a strong effect on a person’s health. There is limited data on racial disparities within lung transplantation (LTx), especially for Hispanic recipients. Therefore, the aim of this study was to identify inequalities that may involve this population. We analyzed historical data from the Organ Procurement and Transplantation Network (OPTN) and performed a retrospective review of Hispanic and Caucasian patients who underwent lung transplantation in the United States between May [...]

This article aims to provide some personal surgical tips to increase the success rate of deep anterior lamellar keratoplasty (DALK), a very advantageous yet complex procedure for treating keratoconus. The most troublesome surgical step is obtaining a successful pneumatic dissection of the deep stromal tissue, allowing the exposure of a deep cleavage plane. The following tips may aid the trainee surgeon in mastering this step, among others: performing a deep trephination, using intraoperative anterior segment optica [...]

Cytomegalovirus (CMV) infection is a common and severe complication following allogeneic stem cell transplantation (ASCT) and requires effective preemptive antiviral therapy. Both oral and intravenous (IV) antiviral agents effectively reduce CMV viral load and achieve viral clearance. Studies comparing oral and IV anti-CMV preemptive treatment in ASCT patients with CMV reactivation showed a potential difference in treatment response and safety profiles between the two administration routes. We retrospectively compa [...]

With the progressive rise in rates of liver transplantation, stagnant donor pool, and social factors, living donor liver transplantation (LDLT) forms the majority of liver transplantations performed in Asian countries. As the global prevalence of metabolic-associated fatty liver disease (MAFLD) is increasing, around 17-25% of all the prospective donors turn out to be steatotic at the time of evaluation and, as such, rejected for donor hepatectomy, thereby considerably reducing the living donor pool. Steatotic graft [...]

Human Leucocyte Antigens (HLA) constitute a highly polymorphic set of genes pivotal to the immune response. The HLA heterozygous advantage hypothesis assumes that heterozygous individuals at the HLA level have a wider range of peptides for T cell recognition than homozygous individuals. Consequently, they possess an enhanced capacity to trigger a targeted immune reaction. The divergent allele advantage hypothesis is an extension of heterozygous advantage, considering the excessive sequence divergence between allele [...]

RICE is salvage therapy for treating CD20+non-Hodgkin lymphoma (NHL). It is combined with G-CSF to collect autologous peripheral blood stem cells (aPBSC). Little data exists, though, on the combination of G-CSF and Plerixafor after RICE in mobilizing adequate number of CD34 cells and the product’s immune content. We report on the results of twenty CD20+ NHL patients after RICE, G-CSF and Plerixafor were given to collect aPBSC. The median number of cells collected was 12.92 × 106 CD34 cells/kg (range 5.4 [...]

Hematopoietic stem cell transplantation (HSCT) is a standard form of cellular therapy for patients suffering from malignant hematological diseases. However, graft-versus-host disease (GVHD) is a very serious complication and a major cause of morbidity and mortality after allogeneic HSCT. Calcineurin inhibitors, such as cyclosporine, are widely used to enhance the survival of patients who have undergone HSCT. Unfortunately, both GVHD and cyclosporine occasionally cause nephropathy. Several studies have shown that th [...]

Lung transplant (LTx) survival and quality of life have been steadily improving, partially from changes in candidate selection for transplantation. There are well-known high-risk factors that lead to poor LTx outcomes, which may be referred to as ‘accounted’ risks. However, there are also other ‘unaccounted’ risks that are not included in the existing model for expected LTx survival to help programs for resource allocation. We performed a retrospective cohort study of all LTx recipients over the age of 18 at UC San [...]

Thrombotic microangiopathy (TMA) in kidney transplant recipients is uncommon and difficult to manage, often with poor graft outcomes [1]. This is a complex and interesting case of an older, highly sensitised kidney transplant recipient who presented with de novo post-transplant TMA in the setting of antibody mediated rejection (ABMR), with other drivers being tacrolimus toxicity, cytomegalovirus (CMV) infection and anti-SARS-CoV-2 BNT162b2 mRNA vaccination. This led to rapid, irrecoverable graft loss. 76-year-old f [...]

Despite the concerted efforts by lung transplant recipients (LTR) and their medical teams, hospital readmissions are common in the first year following transplantation. Reasons for unplanned readmissions include allograft rejection, infections, and respiratory failure before the SARS-COV-2 pandemic. Clinical predictors of readmissions have changed over time with the higher risk factors of acceptable criteria for recipients and donors. We aimed to assess more recent readmission rates based on group classifications t [...]
