AlloSure Lung Assessment and Metagenomics Outcomes Study

ALAMO is a prospective, multi-center, perspective, registry of patients receiving LungCare™ (AlloSure®-Lung, AlloMap Lung, and HistoMap) for surveillance post-transplant. This study aims to evaluate the diagnostic performance characteristics of AlloSure Lung (dd-cfDNA) to detect a spectrum of rejection (ACR, AMR) and allograft infection (Bacterial, Viral, Fungal, Mycobacterial, Parasitic).

Liquid biopsiEs fOr luNg AllogRaft Damage classificatiOn - LEONARDO

LTx has the shortest survival of all solid organ transplants. The complex and time-demanding diagnostics of allograft dysfunction are a significant reason for this. The current study aims overarchingly to improve survival after lung transplantation (LTx) through precise and fast diagnostics. The specific aim is to develop direct-to-clinical implementation biomarkers for the most important aspects of long-term survival after LTx. An in-house-developed PCR-based cell-free-DNA methodology (cf-DNA) will be used for allograft damage and combined with specific other biomarkers to identify damage type. The current clinical golden standard for damage identification will be performed at every sampling instance. The research will be a single-centre prospective observational cohort study. The control samples at all time points will consist of the samples without allograft damage. Blood will be drawn at fixed time points and clinical events. All analyses will be performed at a separate lab, blinded to the patient's status. .

Antimicrobial Therapeutic Drug Monitoring During Lung Transplant Perioperative Phase

Background: Post-LUTX pneumonia represents a leading cause of death along the first month after LUTX. Donor-derived transmission of pathogenic species occurs up to 25% of recipients receiving a graft with a positive BAL culture, despite in-vitro adequate antimicrobial prophylaxis. Hypothesis: LUTX recipients are either exposed to suboptimal antimicrobial doses or antimicrobial penetration into the lug parenchyma is altered either due to surgery (absence of bronchial anastomoses) or to the hyperinflammatory state. Methods: LUTX recipients admitted to the intensive care unit at the Fondazione IRCCS Ca' Granda Policlinico Hospital. According to the institutional perioperative prophylaxis protocol and the donor/recipient ecology the most frequent antimicrobial molecules administered will be: cefepime, vancomycin, and meropenem. Antimicrobial pharmacokinetics will be investigated at three timepoints. Plasma levels of the ongoing antimicrobial molecule will be assessed at ICU admission, on postoperative day 1 and on postoperative day 3. Bronchoalveolar lavage (BAL) samples for the measurement of BAL antimicrobial levels will be collected during the BAL performed for clinical indication on postoperative day 1 and on postoperative day 3. Absolute plasma and BAL antimicrobial levels will be assessed. The ratio of BAL to plasma dosage of antimicrobial will be assessed to evaluate antimicrobial penetration within the target tissue. Correlation between both plasma and BAL antimicrobial dosage and recipients' postoperative fluid balance, body weight, vasopressor requirement, renal function will be performed.

Lung Transplant HCV, Pilot Study

In this study HCV negative recipients will be transplanted with HCV positive lungs. Investigators will attempt to decrease infectivity rates by performing Normothermic Ex vivo Lung Perfusion (EVLP), which is an approved method of donor lung preservation, assessment and treatment, and could be an excellent platform to reduce/eliminate hepatitis C virus. Patients will be treated by the standard approved direct-acting antivirals (DAAs) if infection occurs. It is planned to enroll 20 patients from the Lung transplant wait list in this study. Patients will be actively followed for 6 months including HCV PCR tests and then for up for 5 years to look for evidence of HCV infection and any liver or extra-hepatic complications, as well as standard post-transplant complications. This will be a single center pilot study.
