Superior Isolation of Non-tuberculous Mycobacteria, Including Mycobacterium abscessus Complex, From Lung Transplant Patients Using RGM Medium Compared With Traditional AFB Culture

Early detection of Mycobacterium abscessus complex (MABSC) is crucial for patients with chronic lung disease to enhance the opportunity for potential eradication. Colonisation with MABSC is an absolute contra indication to lung transplantation in many transplant centres. Isolation of MABSC and other non-tuberculous mycobacteria (NTM) by traditional AFB culture is problematic, particularly from patients with cystic fibrosis (CF). Cultures are frequently overgrown by other bacteria or fungi and sputum decontamination procedures can reduce the viability of NTM.

In conclusion, circulating MDSCs are measurable, functional and have a G-MDSC phenotype in lung transplant patients. Their frequency is increased in stable patients, decreased during post-transplant complications, and related to level of immunosuppression. This study may pave the way for further investigations of MDSC in the context of lung transplantation. Introduction From a transplant immunological point of view, graft acceptance is the fundamental element in allograft survival. Graft acceptance is realized by blocking the immune system with immunosuppression preventing host immune cells to recognized and attack...

Cytomegalovirus (CMV) is a betaherpesvirus, the impacts of which are well known to clinicians providing post-transplant cystic fibrosis care. Lung transplant recipients have the highest risk of any solid-organ transplant for CMV reactivation and ganciclovir resistance [1, 2]. Furthermore, CMV reactivation increases the risk of chronic lung allograft dysfunction. However, even in general populations, CMV seropositivity is associated with adverse outcomes including cognitive impairment, frailty, heart disease and all-cause mortality [3–5]. How CMV may contribute to disease is not evident but many streams of evidence su...

CONCLUSION: These new recommendations, close to French practices, help clinicians to find the right time for referral of patients to transplantation centers. This is crucial for the prognosis of lung transplantation. PMID: 31006579 [PubMed - as supplied by publisher]

In this study they also showed PTX3 localized in NETs formed after neutrophil activation (5). Proteomics analysis revealed that PTX3 forms complexes with two anti-microbial proteins [azurocidin (AZU1) and myeloperoxidase (MPO)] associated to NETs (30). More recently, PTX3 localization in NETs has been confirmed, and the colocalization with AZU1 and MPO has been defined more accurately (31). Further investigation will be needed to understand the involvement of PTX3 interaction with AZU1 and MPO in their antibacterial role during NET formation. Regulation of Complement Activation PTX3 interaction with microorganisms is not...

The primary driver of poor outcomes in the early stages of lung transplantation is primary graft dysfunction (PGD). Patients with cystic fibrosis (CF) have unique physiology and demographics compared to other lung transplant recipients. Therefore, we sought to identify risk factors for PGD in the CF patient population undergoing lung transplantation.

Exophiala dermatitidis is a black fungus that frequently colonises the lungs of people with cystic fibrosis (CF). Mucoid and non-mucoid variants can be detected from the same sputum for some patients, but their role in chronic CF lung disease is not fully understood and attempts at early eradication are not routinely performed. Invasive infections with this species are rare; however in 2014 we reported our first case of fatal, invasive infection with a highly mucoid strain of E. dermatitidis in a 34 year old post lung transplant patient with CF.

Lung transplantation is an accepted therapy for patients with end stage lung disease due to Cystic Fibrosis (CF). Up to ten percent of patients with CF are colonized with Achromobacter xylosoxidans, a gram negative organism that due to its intrinsic resistance to many antibiotics may affect negatively impact post-transplant outcomes.
