Endobronchial Mycobacterium avium-intracellulare (MAI) infection has been described in immunocompromised patients but is rare among transplant recipients. We present a case of a 48-year-old male with a history of coal miners' pneumoconiosis who underwent bilateral lung transplantation. Ten months post-transplant, despite normal spirometry and absence of respiratory symptoms, routine surveillance bronchoscopy revealed multiple endobronchial polypoid lesions. Biopsy demonstrated non-necrotizing granulomatous inflammation, with cultures confirming MAI infection. This case underscores the importance of maintaining a high index of suspicion for atypical infections like MAI in lung transplant recipients, even in the absence of overt clinical symptoms. This case's unique presentation adds to our understanding of potential post-transplant complications and may help clinicians recognize similar presentations in the future.

Type A Aortic Dissection Following Abdominal Solid Organ Transplantation: Population-Level Outcomes in the United States.
Clin Transplant
March 2025
Division of Cardiac Surgery, CardioVascular Center, Tufts Medical Center, Boston, Massachusetts, USA.
Background: This study aims to analyze the patient characteristics, clinical outcomes, and contemporary trends concerning type A aortic dissection (TAAD) in previous recipients of abdominal solid organ transplantation (ASOT) in the United States.
Methods: The National Inpatient Sample was queried to identify all patients aged ≥18 with TAAD and a history of ASOT (TAAD-ASOT) between 2002 and 2015Q3 using ICD-9 diagnosis and procedure codes. Baseline characteristics and in-hospital outcomes were compared between TAAD-ASOT patients and TAAD patients without a history of ASOT (TAAD-non-ASOT).
Frequency of Culture-proven Bacterial Infection and Radiographic Pneumonia in Pediatric Heart Transplant Recipients.

Background: Infection is a leading cause of death after pediatric heart transplants (PHTs). Understanding of common pathogens is needed to guide testing strategies and empiric antibiotic use.
Methods: We conducted a 3-center retrospective study of PHT recipients ≤18 years old presenting to cardiology clinics or emergency departments (EDs) from 2010 to 2018 for evaluation of suspected infections within 2 years of transplant.
Immune suppression sustained allograft acceptance requires PD1 inhibition of CD8+ T cells.

Organ transplant recipients require continual immune-suppressive therapies to sustain allograft acceptance. Although medication nonadherence is a major cause of rejection, the mechanisms responsible for graft loss in this clinically relevant context among individuals with preceding graft acceptance remain uncertain. Here, we demonstrate that skin allograft acceptance in mice maintained with clinically relevant immune-suppressive therapies, tacrolimus and mycophenolate, sensitizes hypofunctional PD1hi graft-specific CD8+ T cells.

However, the incidence of opportunistic infections has also increased because of immunosuppression. A common infection after KT is cytomegalovirus (CMV).

Department of Anaesthesiology and Critical Care, Université de Paris, Hôpital Beaujon, AP-HP, Clichy, France.
Background: Perioperative management practices in liver transplantation (LT) evolve very quickly. There are few specific recommendations, often based on a low level of evidence, resulting in wide heterogeneity of practices.
Methods: We performed a survey in all 16 French centers in 2021 by focusing on center organization, preoperative cardiovascular assessment, antimicrobial prophylaxis, hemostasis management, intraoperative use of hemodynamic monitoring and renal replacement therapy, immunosuppression, and postoperative prevention of arterial complications and compared it with current recommendations.
