ABSTRACT
HSCT is associated with a high risk of late morbidity. The aim of this study was to evaluate the frequency, time frame, risk factors, and possible etiology of pulmonary dysfunction following allogeneic HSCT in childhood. We evaluated the pulmonary function of 51 HSCT patients (>6 yr), by including FVC and FEV1 values prior to (baseline) and annually up to five yr after HSCT. A Cox proportional hazards model was used to analyze the risk factors for a pulmonary event. Over half (59%) of the patients developed pulmonary dysfunction, mainly consisting of restrictive abnormalities. Acute GvHD (HR 4.31, 95% CI 1.47-12.63), chronic GvHD (HR 10.20, 95% CI 2.42-43.03), and an abnormal baseline pulmonary function (HR 4.82, 95% CI 1.02-22.84) were associated with post-transplant dysfunction. FEV1 (p < 0.001) and FVC (p < 0.001) declined significantly by 12 months after HSCT and both remained below the pre-HSCT level at up to four yr post-transplantation. HSCT in childhood is associated with early and persistent restrictive impairment of pulmonary function. Patients with extensive chronic GvHD are particularly vulnerable to severe pulmonary dysfunction. Scheduled pulmonary function testing is warranted as part of the follow-up of survivors of HSCT in childhood.
