Primary outcomes 1. Nephrotoxicty i) serum (blood) creatinine levels ii) creatinine clearance iii) urinary excretion of protein iv) urinary excretion of biomarkers of proximal tubular toxicity Secondary outcomes 1. Eradication of respiratory infection 2. Participant-reported symptom scores 3. Lung function parameters 4. Participant-reported QoL scores 5. Adverse effects of treatment
