Background: A pilot evaluation to assess the safety and possible benefits of TLC C-53, (prostaglandin E1 associated with egg phosphatidylcholine liposomes) in acute respiratory exacerbations in children with cystic fibrosis (CF). Methods: Randomised, double-blind, placebo-controlled study in 20 P. aeruginosa colonised patients. All received intravenous antibiotics. Subjects were given a rising dose of TLC C-53 (0.15-1.8 μg/kg) by 4 x 1-h infusions. Primary outcome measures were sputum IL-6, IL-8 and sputum neutrophil elastase. The rate of decline in lung function was determined at 6 weeks post-therapy as was the interval until the next respiratory exacerbation requiring intravenous antibiotic therapy. Results: Analysis of primary and secondary outcome measures failed to show any significant differences between the two groups, although trends favoured the treated group. Decline in lung function over 6 weeks favoured the TLC C-53 group (FEV1 mean difference 4.3%, 95% CI= -6.8, 15.4%). Time to next exacerbation also favoured the TLC C-53 group with a mean time to exacerbation for TLC C-53 of 26.0 weeks against 11.9 weeks. Conclusions: A larger multi-centre trial of TLC C-53 as an adjunct to antibiotic therapy in respiratory exacerbations in CF would appear warranted. © 2002 European Cystic Fibrosis Society.
