Sedation with Propofol for Bronchoscopy in Cystic Fibrosis Lung Transplant Recipients

AbstractIntroductionFlexible fiberoptic bronchoscopy (FFB) plays an important role in the surveillance of cystic fibrosis (CF) patients after lung transplantation (LTx). With rapid onset and clearance, propofol provides a safe and efficient method for sedation during FFB, yet sedation requirements for CF patients are not well described.ObjectivesDue to pharmacokinetic differences for other classes of drugs in CF patients, this study was performed to examine propofol requirements for sedation during bronchoscopy in lung transplant recipients with CF.MethodsA single-center retrospective cohort study was performed to examine propofol sedation requirements during outpatient surveillance. FFB procedures with transbronchial biopsy (TBB) in post-LTx recipients between 2009 and 2014 were conducted.ResultsA total of 40 FFB procedures with TBB were performed 20 CF (11 females), 20 non-CF (11 females). Mean ( ± SD) age was 25.6 ± 9.2 (range 13–42) years and 22.2 ± 10.8 (range 11–39) years for the CF and non-CF groups, respectively. Propofol requirements were significantly higher in the CF patients compared to the non-CF patients. Mean (± SD) propofol dose for CF patients was 334 ±  86 versus 214 ± 88 mg for non-CF patients (p

Cystic Fibrosis pulmonary disease is characterized by chronic airway infections and concomitant non-resolving inflammation that usually leads to respiratory failure within the fourth decade of life. The disease results from patients bearing two mutant copies of the cystic fibrosis transmembrane conductance regulator (CFTR), a channel that transports chloride and bicarbonate [1]. Over 2000 different mutations in CFTR have been identified, and these mutations are associated with varying severity of disease based on how much residual CFTR activity remains.

AbstractThe contribution of T-cells after lung transplant (LTx) remains controversial with no current consensus of their role concerning chronic lung allograft dysfunction. Using flow cytometry to assess T-cell subsets of bronchoalveolar lavage fluid (BALF) in 16 cystic fibrosis (CF) LTx recipients, we identified a decline in CD4+ T-cell frequency and an increase in CD8+ T-cell frequency in patients who developed severe bronchiolitis obliterans syndrome (BOS) (N = 10) when comparing baseline (6 months post-LTx) and follow-up (most recent bronchoscopy—clinical or surveillance per protocol). Comparin...

CONCLUSIONS: We found no evidence that adding hip core decompression to physical therapy achieves clinical improvement in people with sickle cell disease with avascular necrosis of bone compared to physical therapy alone. However, we highlight that our conclusion is based on one trial with high attrition rates. Further randomized controlled trials are necessary to evaluate the role of hip-core depression for this clinical condition. Endpoints should focus on participants' subjective experience (e.g. quality of life and pain) as well as more objective 'time-to-event' measures (e.g. mortality, survival, hip longevity). The a...

Abstract Airway surface dehydration is a pathological feature of cystic fibrosis (CF) lung disease. CF is caused by mutations in the CF transmembrane conductance regulator (CFTR), a cyclic AMP-regulated Cl- channel controlled in part by the adenosine A2B receptor. An alternative, CFTR-independent mechanism of fluid secretion is regulated by ATP, via the P2Y2 receptor (P2Y2R) that activates Ca2+-regulated Cl- channels (CaCC/TMEM16) and inhibits Na+ absorption. However, due to rapid ATP hydrolysis, steady-state ATP levels in CF airway surface liquid (ASL) are inadequate to maintain P2Y2R-mediated fluid secretion. Th...
