Immunosuppression Drug Therapy in Lung Transplantation for Cystic Fibrosis

This article provides a review of immunosuppression regimens in the pediatric and adult CF post-LTx population, investigating drug dosing and monitoring, and medication combinations. Currently used immunosuppressive medications and related systemic adverse effects are reviewed. With limitations of data in the pediatric population, future research should address immunosuppression in these children to help guide pediatric drug management as a means to optimize clinical outcomes after LTx.

A pediatric patient with cystic fibrosis and a double-lung transplant received a genetically engineered 3-phage cocktail to treat a life-threatening antibiotic-resistant Mycobacterium abscessus infection for which all standard therapeutic options had been exhausted. Over 7 months of twice-daily intravenous infusions, as well as daily topical phage therapy, the 15-year-old patient ’s surgical wound and skin lesions healed gradually and her lung and liver function improved. No adverse reactions to the treatment were reported.

Abstract Bacteria have acquired multiple mechanisms to evade the lethal effects of current therapeutics, hindering treatment of bacterial infections such as the pathogen P. aeruginosa, which is responsible for nosocomial and cystic fibrosis lung infections. One resistance mechanism involves membrane-embedded multidrug efflux pumps that can effectively extrude an array of substrates, including common antibiotics, dyes, and biocides. Among these is the small multidrug resistant (SMR) efflux protein, consisting of four transmembrane helices (TMs), that functions as an antiparallel dimer. TMs 1-3 comprise the substrat...

Staphylococcus aureus is the most commonly identified airway colonizer of cystic fibrosis (CF) patients, and infections with methicillin-resistant S. aureus (MRSA) are associated with poor outcomes. Yet, little is known about the intrahost evolution of S. aureus among CF patients. We investigated convergent evolution and adaptation of MRSA among four CF patients with long-term respiratory carriage. For each patient, we performed whole-genome sequencing on an average of 21 isolates (range: 19-23) carried for a mean of 1,403 days (range: 903-1,679), including 25 pairs of isolates collected on the same day. We assessed intrah...

The aim of the study was to evaluate the impact of manual cleaning and manual cleaning followed by Ultraviolet-C disinfection on the colony forming units of bacteria retrievable from equipment and surfaces within clinic rooms following a CF outpatient encounter. While UV disinfection has proven to be effective within general healthcare settings, it has not been evaluated in a CF centre.Microbiological sampling was performed following outpatient encounters involving 11 adult patients with CF and chronic infection with P.aeruginosa, MRSA or E.

Isabelle Carnell-Holdaway, 17, has faced not one but two unrelenting threats to her life. Diagnosed at 11 months of age with cystic fibrosis, the progressive genetic disease that causes lung infections and breathing impairment, Isabelle has also combated an on-again, off-again infection caused by antibiotic-resistant bacteria since age 8.
