Special Issue Information

Dear Colleagues,

Lung transplantation remains a life-saving intervention for patients with end-stage lung diseases such as idiopathic pulmonary fibrosis, chronic obstructive pulmonary disease, cystic fibrosis, and pulmonary arterial hypertension. This Special Issue on lung transplantation brings together leading research and expert perspectives to address critical developments and persistent challenges in the field.

The articles featured in this issue will cover a broad range of topics, from innovations in organ preservation and ex vivo lung perfusion to advances in recipient selection.

By integrating clinical insights with cutting-edge research, this issue aims to support multidisciplinary teams in optimizing outcomes for lung transplant recipients. The collection provides a valuable resource for clinicians committed to advancing lung transplantation as a sustainable and effective therapy for end-stage lung disease.

Abstract
Background/Objectives: Chronic lung allograft dysfunction (CLAD) remains the leading cause of late graft failure after lung transplantation (LuTX). De novo donor-specific anti-HLA antibodies (dnDSA), especially HLA-DQ, have been implicated; we assessed associations between dnDSA (class and specificity) and CLAD after LuTX.

Background/Objectives: Chronic lung allograft dysfunction (CLAD) remains the leading cause of late graft failure after lung transplantation (LuTX). De novo donor-specific anti-HLA antibodies (dnDSA), especially HLA-DQ, have been implicated; we assessed associations between dnDSA (class and specificity) and CLAD after LuTX. Methods: We retrospectively analyzed all LuTX recipients transplanted from 2005–2018 at a single center (n = 585). dnDSA were measured by Luminex single-antigen bead assays (MFI > 1000) at 1, 3, 6, and 12 months and at least annually thereafter. CLAD was defined by ISHLT criteria; time-to-event comparisons used log-rank testing. Results: dnDSA developed in 151/585 recipients (25.8%), predominantly class II (129/585; 22.1%); class I dnDSA occurred in 52/585 (8.9%). CLAD occurred more frequently in dnDSA-positive than dnDSA-negative recipients (64/151; 42.4% vs. 109/434; 25.1%; p < 0.0001). Rejection-attributed death was higher in dnDSA-positive recipients (19/151; 11.3% vs. 25/434; 5.3%; p = 0.01). Both class I and class II dnDSA were associated with higher CLAD rates (log-rank p < 0.001 each). Locus-specific analyses identified HLA-DQ dnDSA as strongly associated with CLAD (p < 0.0001); DQ7 was the most frequent specificity (n = 44) and showed the strongest association (p < 0.0001). Conclusions: dnDSA after LuTX were associated with increased CLAD incidence and rejection-attributed mortality, with a prominent association for HLA-DQ—particularly DQ7. Full article

Lung transplantation provides a curative option for patients living with end-stage lung disease, with a goal of improving survival and quality of life. Chronic lung allograft dysfunction, or CLAD, represents a major cause of morbidity and mortality, particularly after the first year of transplant. Background/Objectives: The goal of this review is to outline the diagnosis and management of CLAD within the lung transplant population, as well as discuss future areas of potential research interest. Methods: A PubMed literature review of relevant publications regarding CLAD epidemiology, diagnosis, and management was performed to assess current understandings. Results: CLAD is the leading cause of death in lung transplant patients following the first year of transplant, and is common, with approximately 50% of patients exhibiting some degree of CLAD within five years of surgery. Well-established guidelines on diagnosis were recently published to aid clinicians in diagnosing and characterizing CLAD. Several medical and surgical interventions exist, although no therapy consistently and reliably stabilizes or reverses CLAD. Conclusions: CLAD management remains a priority within the lung transplant field as a leading cause of morbidity and mortality. Full article

Objectives: Lung transplantation is a life-saving option for patients with end-stage lung diseases, yet immunosuppression management remains challenging. Induction therapy with interleukin-2 receptor antagonists (IL2-AR), such as basiliximab and daclizumab, is designed to reduce acute rejection and improve graft survival. However, its efficacy compared with alternative agents or no induction therapy remains uncertain. This study aimed to evaluate the impact of IL2-AR induction on clinical outcomes in lung transplant recipients. Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines. Studies comparing IL2-AR induction with antithymocyte globulin (ATG), alemtuzumab, or no induction therapy were included. The primary outcomes were overall survival and freedom from acute rejection. Secondary outcomes included freedom from bronchiolitis obliterans syndrome (BOS), hospital length of stay (LOS), and time until extubation. Kaplan–Meier curves were reconstructed for long-term outcomes. Random effects model was performed. Results: Twelve studies comprising 27,855 patients were included. IL2-AR induction was associated with improved overall survival compared to standard of care (HR 0.88; 95%CI 0.85–0.93; p < 0.01). However, sensitivity analyses, including two-stage meta-analysis and leave-one-out analysis, revealed a loss of statistical significance. No significant differences were found for freedom from acute rejection (p = 0.774) or secondary outcomes, including freedom from BOS (p = 0.455), hospital LOS (p = 0.423), and time until extubation (p = 0.186). Conclusions: IL2-AR therapy may be associated with improved survival after lung transplantation; however, evidence remains inconclusive due to heterogeneity and limitations in study design.
