Cryptococcosis is a common invasive fungal infection in solid organ transplant recipients (SOTR) that can be challenging to manage. We discuss a case of disseminated cryptococcosis in a transplant recipient. A 26-year-old woman with a history of ESRD from C1q nephropathy, living-related kidney transplant in early 2012, and allograft nephrectomy in 2015, received a deceased donor kidney transplant (DDKT). Induction after the first transplant was anti-thymocyte globulin (ATG) and maintenance immunosuppression (IS) in [...]

Liver transplant recipients (LTRs) are at risk for vancomycin-resistant Enterococcus (VRE) infections which can lead to significant morbidity or mortality. Antibiotic exposure, including vancomycin, is associated with greater risk of VRE infection. This study aimed to assess the appropriateness of vancomycin use and rates of VRE infection in this population. We performed a retrospective cohort study of 327 patients who underwent liver transplantation at our center from January 1, 2012 to June 30, 2017. Sixty (18.3% [...]

Background: Hematopoietic cell transplant (HCT) patients are a high-risk population for poor nutrition and decreased survival. There is little data on how nutrition in pediatric HCT patients affects need for critical care interventions and outcomes. Methods: We hypothesized that patients who did not meet goal nutrition by 72 hours post-admission to the pediatric intensive care unit (PICU) had increased in-hospital mortality and increased need for critical care interventions. We performed a retrospective cohort stud [...]

Transplantation is a widely accepted and successful life-saving treatment for hundreds of thousands of patients. However, transplant medicine still faces a number of obstacles. One of the most significant is the large disparity between the number of donors and recipients and the growing need for re-transplantation. In the last two decades, the improvement and organization of the national transplantation program in Croatia have resulted in a steadily increasing donor rate and therefore the transplantation numbers. A [...]

Fluid management intra- and post-operatively for kidney transplant recipients (KTR) is essential to maintain adequate perfusion to the kidney. 0.9% normal saline (NS) is commonly used, but it can cause hyperchloremic metabolic acidosis, which may result in hyperkalemia and lead to delayed graft function (DGF). Plasma-Lyte A (PA) is an alternative option that has a lower amount of chloride and a neutral pH, which may offset the risk of hyperkalemia. The aim of this study is to determine the incidence of DGF in KTRs [...]

Graft-versus-host disease (GVHD) is a serious complication that may occur in patients receiving allogeneic hematopoietic stem cell transplant (HSCT). GVHD occurs because of the immunological reaction between the donor’s T cells and the recipient’s antigens; GVHD may develop in different tissues, including the eye. Corneal perforation is an uncommon but vision-threatening manifestation of GVHD. We reported the case of a 65-year-old male patient who developed corneal perforation sequentially in both eyes 3 years afte [...]

IgAN is a major cause of end-stage kidney disease (ESKD) leading to kidney transplantation in a significant proportion of patients. However, its recurrence in transplanted kidneys can lead to graft loss. The rate of graft loss attributable to IgAN after transplantation is variably reported in different retrospective cohorts. Previous reports describe recurrence rates of 22-58% with a 1.3% to 16% rate of graft loss. Accurate diagnosis and prediction of graft loss are important for planning effective therapies to imp [...]
