Early extracorporeal photopheresis treatment is associated with better survival in patients with chronic or recurrent acute lung allograft dysfunction. J Clin Apher 2024; 39:e22128.

Abstract
BACKGROUND Due to development of chronic lung allograft dysfunction (CLAD), prognosis for patients undergoing lung transplantation (LTx) is still worse compared to other solid organ transplant recipients. Treatment options for slowing down CLAD progression are scarce with extracorporeal photopheresis (ECP) as an established rescue therapy. The aim of the study was to identify characteristics of responders and non-responders to ECP treatment, assess their survival, lung function development and by that define the subset of patients who should receive early ECP treatment. METHODS We performed a retrospective study of all LTx patients receiving ECP treatment at the University Hospital Zurich between January 2010 and March 2020. Patients were followed-up for a maximum period of 5 years. Mortality and lung function development were assessed by CLAD stage and by CLAD subtype before initiation of ECP treatment. RESULTS Overall, 105 patients received at least one ECP following LTx. A total of 57 patients (61.3%) died within the study period with a median survival of 15 months. Mortality was 57% for patients who started ECP at CLAD1, 39% for CLAD2, 93% for CLAD3, and 90% for CLAD4 (p < 0.001). Survival and lung function development was best in young patients at early CLAD stages 1 and 2. Response to ECP treatment was worst in patients with CLAD-RAS/mixed subtype (14.3%) and patients with ECP initiation in CLAD stages 3 (7.1%) and 4 (11.1%). Survival was significantly better in a subset of patients with recurrent acute allograft dysfunction and earlier start of ECP treatment (105 vs 15 months). CONCLUSION In this retrospective analysis of a large group of CLAD patients treated with ECP after LTx, early initiation of ECP was associated with better long-term survival. Besides a subset of patients suffering of recurrent allograft dysfunction, especially a subset of patients defined as responders showed an improved response rate and survival, suggesting that ECP should be initiated in early CLAD stages and young patients. ECP might therefore prevent long-term disease progression even in patients with CLAD refractory to other treatment options and thus prevent or delay re-transplantation.

Effective Extracorporeal Photopheresis of Patients with Transplantation Induced Acute Intestinal GvHD and Bronchiolitis Obliterans Syndrome. Biomedicines 2022; 10:biomedicines10081887. [PMID: 36009436 PMCID: PMC9405770 DOI: 10.3390/biomedicines10081887] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 07/30/2022] [Accepted: 08/02/2022] [Indexed: 12/03/2022] Open
Abstract
Background: Patients with steroid-refractory intestinal acute graft-versus-host disease (aGvHD) and bronchiolitis obliterans syndrome (BOS) represent a population with a high need for alternative and effective treatment options. Methods: We report real-life data from 18 patients treated with extracorporeal photopheresis (ECP). This cohort consisted of nine patients with steroid-refractory intestinal aGvHD and nine patients with BOS. Results: We document partial or complete clinical response and reduction of symptoms in half of the patients with intestinal acute GvHD and patients with BOS treated ECP. Responding patients tended to stay on treatment longer. In patients with BOS, stabilization of lung function and forced expiratory volume was observed, whereas, less abdominal pain, less diarrhea, and a reduction of systemic corticosteroids were seen in patients with intestinal acute GvHD. Conclusions: ECP might not only abrogate symptoms but also reduce mortality caused by complications from high-dose steroid treatment. Taken together, ECP offers a serious treatment avenue for patients with steroid-refractory intestinal acute GvHD and BOS.

Relationship between FEV 1 decline and mortality in patients with bronchiolitis obliterans syndrome-a systematic literature review. Respir Med 2021; 188:106608. [PMID: 34517199 DOI: 10.1016/j.rmed.2021.106608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 08/24/2021] [Accepted: 09/05/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Bronchiolitis obliterans syndrome (BOS) is one of the most severe complications and the leading cause of late mortality and morbidity after lung transplantation (LT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT). No approved treatment for BOS is available. This review aimed to systematically identify and summarise the findings regarding the relationship between FEV1 decline and mortality in patients who developed BOS following LT or allo-HSCT. METHODS A systematic literature search was performed in the Medline, Embase and Cochrane reviews databases. Of the 501 potential studies identified 25 met inclusion criteria and were analysed. RESULTS Overall, 13 studies reported a relationship between FEV1 and mortality, and 12 studies reported both mortality and FEV1 results but did not investigate the relationship between them. There was heterogeneity in the analyses, which investigated the relationship between FEV1 decline and mortality across the studies in terms of levels of lung functioning, comparison to a control group, treatment, and statistical methodology; nevertheless, a clear and consistent increase in the risk of death associated with FEV1 decrease was seen in the analysed studies. CONCLUSIONS The systematic literature review identified studies and findings that support a relationship between FEV1 and mortality, with a decrease in FEV1 being statistically associated with increased risk of death. Knowing that lower FEV1 levels are associated with higher mortality rates may help assess the condition of a patient with BOS and monitor future treatment effectiveness. However, more evidence is needed to further investigate this relationship and to verify its clinical usefulness.

Abstract
The primary factor that limits long-term survival after lung transplantation is chronic lung allograft dysfunction (CLAD). CLAD also impairs quality of life and increases the costs of medical care. Our understanding of CLAD continues to evolve. Consensus definitions of CLAD and the major CLAD phenotypes were recently updated and clarified, but it remains to be seen whether the current definitions will lead to advances in management or impact care. Understanding the potential differences in pathogenesis for each CLAD phenotype may lead to novel therapeutic strategies, including precision medicine. Recognition of CLAD risk factors may lead to earlier interventions to mitigate risk, or to avoid risk factors all together, to prevent the development of CLAD. Unfortunately, currently available therapies for CLAD are usually not effective. However, novel therapeutics aimed at both prevention and treatment are currently under investigation. We provide an overview of the updates to CLAD-related terminology, clinical phenotypes and their diagnosis, natural history, pathogenesis, and potential strategies to treat and prevent CLAD.

Abstract
BACKGROUND Two extracorporeal photopheresis (ECP) instruments, the CELLEX and the UVARXTS are currently being used "off-label" in the US for treatment of graft versus host disease (GVHD). Our study compared the performance of the two instruments in the setting of acute and chronic GVHD. STUDY DESIGN AND METHODS We retrospectively analyzed the outcomes of patients with steroid refractory or steroid resistant GVHD undergoing ECP at Barnes Jewish Hospital. Multivariate logistic regression was used to evaluate the comparative efficacy of the two instruments with respect to steroid dose reduction (≥50% from baseline) and clinical improvement in GVHD. Chi-square/Fisher exact tests were used to compare the incidence of adverse events, while multivariate Cox regression was employed to assess a potential difference in mortality between the two instrument treatment cohorts. RESULTS After adjusting for potential confounders, there was no significant difference in the odds of steroid dose reduction (OR = 1.41, 95% confidence interval [CI]: 0.51-3.90, p = 0.50) or clinical improvement (OR 2.0, 95% CI: 0.63-6.41, p = 0.24) between the two instrument treatment cohorts. The frequency of adverse events (CELLEX 45.4%; UVAR XTS 40.5%, p = 0.55) was also comparable between the cohorts. There was no significant difference in mortality of either acute or chronic GVHD patients when treated by the CELLEX as compared to the UVAR-XTS (aHR 0.66, 95% CI: 0.35-1.25, p = 0.20). CONCLUSION The efficacy and safety of the two ECP instruments, the CELLEX and the UVAR-XTS, are comparable for the treatment of acute and chronic GVHD.
