Long-term Prognosis of Childhood Chronic Suppurative Lung Disease

"Long Term prognosis of Chronic Suppurative Lung Disease Prof Dr Anna Marie Nathan Non-CF Bronchiectasis (NCFBE) and CSLD are the leading causes of BE in Asia. Recent interest has moved NCFBE out of the “orphan” disease category. Paediatric bronchiectasis is reversible with timely diagnosis and effective treatment (1). However, data on the ideal management of NCFBE remain limited, with a limited armamentarium of treatment options, especially in children, where randomised trials are severely lacking 1. We have published data on children with CSLD/BE 2. Seventy-eight per cent of children who performed spirometry had values <80% of the normal predicted value. Anthropometric measurements in children with NCFBE were static despite treatment. PC-QOL scores were low 2. A study from Thailand found that pulmonary exacerbation occurred in 80% of children, with a higher rate in non-infectious bronchiectasis than postinfectious bronchiectasis (90.9% vs 61.5%, p = 0.036). Hospitalisation was required for 77.1% of children, with a higher rate of non-infectious bronchiectasis than postinfectious bronchiectasis (86.3% vs 53.8%, p = 0.033) 3. Seventy-seven per cent of interviewed parents had abnormal DASS21 scores, with 54% being stressed and 51% being depressed. Parents of children diagnosed with CF had significantly lower DASS21 scores, hence indicating better mental health scores compared to non-CF CSLD 2. The presence of Pseudomonas aeruginosa (Pa) in the airways of patients with non-CF bronchiectasis has been associated with accelerated lung function decline and increased morbidity and mortality. Guidelines suggest inhaled antibiotics to promote eradication 1(1). We have found that eradication is associated with improved quality-of-life outcomes, with significant improvements in PC-QoL scores and cough scores after 3 months of treatment observed in patients who received both systemic and inhaled antibiotics (P = 0.002 and P = 0.003, respectively), but not in patients who received inhaled antibiotics alone (P = 0.09 and P = 0.89, respectively 4. In a study examining long-term outcomes of childhood bronchiectasis, young adults with bronchiectasis rarely attended adult respiratory clinics despite being symptomatic and having multiple emergency doctor visits5. This reflects inefficient transition programmes for our patients, which will translate to very poor adult outcomes. References 1.Chang, A.
