BACKGROUND: Neonatal autosomal-recessive polycystic kidney disease (ARPKD) is associated with pulmonary hypoplasia and severe respiratory distress. There is no published information on long-term lung function in ARPKD survivors.
METHODS: Pulmonary function tests, including spirometry and diffusion capacity, were performed in a nationwide cohort of Finnish paediatric patients with ARPKD. The annual incidence of respiratory infections and the need for permanent asthma medication were also evaluated in this population.
RESULTS: Pulmonary function in 11 children surviving the neonatal period was good when measured after a median follow-up time of 10.4 years (range 5.4-16.1 years). None of the patients required oxygen supplementation, and only one patient had asthma. Patients who had received ventilator therapy during infancy had significantly lower maximal instantaneous forced expiratory flow (MEF%) (66%; 43-93% vs 105%; 63-110%; p=0.048) and forced expiratory volume/forced vital capacity (0.76; 0.7-0.81 vs 0.89; 0.77-0.91; p=0.03) than patients without a history of mechanical ventilation, suggesting tendency for airway obstruction in the former group of patients. The frequency of respiratory infections did not differ from Finnish paediatric population in general.
CONCLUSIONS: The results of pulmonary function tests were within reference values for most patients with ARPKD, which suggested good long-term lung prognosis. Lung function tests should be considered for patients with ARPKD with a history of mechanical ventilation during infancy.
