Treatment: Drugs: Dornase Alfa
Once daily, 2.5ml inhaled dornase alfa (evening if able) with inhalational breathing routine (IBR). IBR consists of 4 slow deep breaths followed by 6 relaxed breaths, repeated until nebuliser is complete, coughing when the patient feels the need to expectorate. The patient will be instructed to sit in an upright position with upper limb support as able.

Summary
Brief summary
Patients who have undergone lung transplantation are at an increased risk of developing chest infections due to long-term medication suppressing the immune response. In other chronic lung diseases such as cystic fibrosis (CF) and bronchiectasis, inhaled, nebulised mucolytic medication such as dornase alfa and isotonic saline are often used as part of the management of lung disease characterized by increased or retained secretions. These agents act by making it easier to clear airway secretions, and are currently being used on a case-by-case basis post lung transplantation.

To the investigators knowledge, these agents have not been evaluated via robust scientific investigation when used post lung transplant, yet are widely used in routine practice. Patients post lung transplant must be investigated separately as they exhibit differences in physiology that make the clearance of sputum potentially more difficult when compared to other lung diseases. Lower respiratory tract infections are a leading cause of hospital re-admission post lung transplant. Therefore, this highlights the need for a randomized controlled trial. The aim of this study is to assess the efficacy of dornase alfa, compared to isotonic saline, in the management of lower respiratory tract infections post lung transplant. Investigators hypothesize that dornase alfa will be more effective than isotonic saline.

The effect of a daily dose of dornase alfa and isotonic saline will be compared over a treatment period of 1 month. Patients admitted to hospital suffering from chest infections characterized by sputum production post lung transplant will be eligible for study inclusion. Patients will be followed up through to 3 months in total to analyze short-medium term lasting effect. Investigators wish to monitor physiological change within the lung non-invasively via lung function analysis whilst assessing patient perceived benefit via cough specific quality of life questionnaires. These measures will be taken at study inclusion and repeated after 1 month and 3 months. Day to day monitoring will be performed via patient symptom diaries, incorporating hospital length of stay and exacerbation rate. The outcomes of this study have the potential to guide clinical decision-making and highlight safe and efficacious therapies.
