Detection of Activated Pepsin in Bronchoalveolar Lavage and Acute Cellular Rejection in Lung Transplant RecipientsAbstract
Activated pepsin (pepA) in bronchoalveolar lavage (BAL) fluid may be a biomarker of gastric aspiration. We sought to i) evaluate the association of pepA in BAL fluid with acute cellular rejection (ACR) in a cohort of lung transplant recipients (LTRs), ii) assess the association between pepA and isolation of typical gastrointestinal microorganisms from BAL fluid, and iii) explore the accuracy of using pepA concentration as a biomarker of ACR. After IRB approval, we conducted a retrospective observational study analy [...] 80 474 |
Management of Calcareous Corneal Degeneration from Medication Washout to Corneal Transplantation. Case Series and Review of the LiteratureAbstract
Calcareous corneal degeneration is a rare disease characterized by calcium phosphate deposition into the deep corneal layers. Corneal calcification has a multifactorial origin and is associated with various systemic and ocular conditions. Several treatment options showed promising results in the management of this disorder. Herein, two cases of calcareous degeneration occurring postoperatively in patients undergoing surgery for retinal detachment (case #1) and glaucoma (case #2) were reported. Despite normal serum [...] 90 662 |
Circulating lncRNAs HOTTIP and HOTAIR as Potential Biomarkers in Crigler-Najjar Syndrome: A Preliminary Report from Shiraz Liver Transplant Research Centerby

Crigler-Najjar syndrome (CNS) is a rare autosomal recessive disorder characterized by impaired bilirubin metabolism, leading to neurotoxic unconjugated bilirubin accumulation. Liver transplantation remains the only effective treatment, highlighting the need for novel diagnostic and therapeutic approaches. Long non-coding RNAs (lncRNAs) have emerged as potential biomarkers in various diseases, including cancer. This study aimed to evaluate the expression of lncRNAs HOTTIP and HOTAIR in CNS patients and healthy contr [...] 100 653 |
Is Donation after Circulatory Determination of Death in Japan Uncontrolled or Controlled?Abstract
Using donation after circulatory determination of death (DCD) donors has been shown to be a potential means of increasing the number of donors for organ transplantation. The purpose of this study was to examine the published practice of DCD in Japan to properly define their practice as controlled or uncontrolled. Through the Web of Science database, we systematically searched articles describing uncontrolled DCD, controlled DCD or Maastricht classification. A total of 12 articles (ten articles related to kidney, on [...] 122 871 |
Advances in Managing Infections in Lung Transplantation: A Reviewby
![]() ![]() Abstract
Transplanted lung allografts are particularly susceptible to infection among SOT due to the constant exposure to the environment, aggressive immunosuppressive strategies, and impaired clearance mechanisms after denervation of the transplanted lung. Though prophylactic antimicrobial, antifungal, and antiviral regimens are used as preventive strategies to mitigate the risk of infection, complications related to allograft infection remain one of the primary causes of morbidity and mortality after lung transplantation.

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 [...] 223 1065 |
Low Mortality Associated with COVID-19 Infection in Lung Transplant Recipients at a Single Centerby

Lung Transplant Recipients (LTR) are particularly vulnerable to severe infection, hospitalization, and death due to community acquired respiratory viruses. As a result, the global SARS-Cov-2 pandemic poses a higher risk to this population. We aim to study the lung function, severity of infection and mortality among LTR at a single center. A retrospective chart review was performed on all LTR at the University of San Diego, California Medical Center between June 2020 and September 2022. Spirometry was performed at 1 [...] 216 1165 |
Contribution of a Single Islet Transplant Program to Basic Researchers in North America, Europe, and Asia through Distributing Human Isletsby

There has been a steady expansion in islet isolation and transplantation activity worldwide. In addition to preparing human islets for transplantation, we have been providing human islets to basic researchers. The aim of this study was to review the activity of distribution of human islets to basic researchers in North America, Europe, and Asia, and to investigate if there are any differences in utilization rate of islets among three continents. We reviewed our islet isolation batch files, donor records, and docume [...] 258 1818 |
Thrombotic Microangiopathy in Solid Organ Transplantationby
![]() ![]() ![]() ![]() ![]() ![]() Abstract
Thrombotic Microangiopathy (TMA) is a syndrome characterized by microangiopathic hemolytic anemia (MAHA) and thrombocytopenia. The presence of schistocytes on peripheral smear, a negative Coombs test, elevated lactate dehydrogenase, increased reticulocyte count and low haptoglobin are often the clues for MAHA. The microvascular process often targets vasculature in kidneys, brain, gastrointestinal system, heart, and skin. A timely diagnosis and treatment are often crucial to prevent severe end organ damage and death [...] 223 1360 |
Management of Steatosis in Living Donors: Where Do We Stand?Abstract
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 [...] 158 1046 |
