Elkin S, Geddes D, 2003, Pseudomonal infection in cystic fibrosis: the battle continues., Expert Rev Anti Infect Ther, Vol: 1, Pages: 609-618, ISSN: 1478-7210

Pseudomonas aeruginosa lung infection is the major cause of morbidity and mortality in patients with cystic fibrosis. Infection usually begins in childhood and is responsible for respiratory failure and death in most patients with cystic fibrosis. The organism triggers an exuberant chronic inflammatory reaction which damages the airways and leads to progressive loss of lung function. Over the last decade significant advances have been made in the understanding of the pathophysiology of cystic fibrosis airways disease. These should assist the development of new and better therapies to treat this pathogen. This review provides an overview of pseudomonal infection in cystic fibrosis, including mechanisms by which the bacteria may colonize the cystic fibrosis airway, persistence of pseudomonal infection and the biofilm mode of growth. Available treatments and possible novel approaches to therapy will be discussed.

Alton E, Geddes D, 1995, The prospects for gene therapy in cystic fibrosis., Curr Opin Pulm Med, Vol: 1, Pages: 471-477, ISSN: 1070-5287

Gene therapy provides the best prospect of a fundamental new treatment for cystic fibrosis. The lungs are the most important target, because this organ is the most severely affected by the disease and is also accessible for topical treatment. Advances in this field have been very rapid, and the prospects remain good although a number of problems need to be overcome. The two main approaches to gene transfer, namely adenoviruses and liposomes, are efficient in vitro, but early clinical trials have shown that they work less well in vivo. A number of proof of concept studies have shown that gene transfer is possible, but full functional correction of the cystic fibrosis defect has not yet been achieved. Adenoviruses have provoked an inflammatory response, and new viral vectors are being developed to overcome this. Existing lipids are relatively inefficient, but new liposomes are being developed to enhance gene transfer. Much work needs to be done to improve safety and efficacy of gene transfer before materials are ready for large scale clinical trials. However, progress is very rapid, and there is a real prospect of developing an effective gene therapy for cystic fibrosis within the next decade.

Chronic pulmonary infection is the major cause of morbidity and mortality in cystic fibrosis. High levels of DNA in the sputum make the sputum viscous and difficult to expectorate. Recombinant human deoxyribonuclease (rhDNase) in vitro has been shown to reduce the viscoelasticity of the sputum from CF patients. We have done a phase II double-blind randomised placebo-controlled trial in which patients received either 2.5 mg rhDNase twice daily or placebo for 10 days. All patients had forced vital capacity (FVC) above 40% predicted and were clinically stable. Patients were followed up for 42 days from the start of drug/placebo administration. All 71 randomised patients, aged 16-55, completed every aspect of the study and baseline characteristics were similar in the two groups. Baseline forced expiratory volume in one second (FEV1) was 46% of predicted for patients randomised to rhDNase, and 48% for those randomised to placebo; and baseline FVC was 76% of predicted for both groups. The mean percentage change in FEV1 from baseline was a 13.3% rise on rhDNase and a 0.2% fall on placebo (p < 0.001). FVC rose 7.2% in the rhDNase group and 2.3% in the placebo group (not significant). There were no life-threatening adverse events and no anaphylactic reactions. There was no significant difference in side-effects between the groups. This study confirms that short-term administration of rhDNase in stable patients with cystic fibrosis is safe and improves lung function.
