Lymphangioleiomyomatosis (LAM) is a rare multisystem disease. Progressive airflow limitation, pneumothorax and angiomyolipoma-related bleeding are major morbidities. As treatments are available for these complications, we prospectively audited loss of FEV1 (ΔFEV1), pneumothorax and angiomyolipoma bleeding against clinical standards over 4 years at the UK Clinical Centre. ΔFEV1 for these patients is lower than previously reported and rates of pneumothorax and angiomyolipoma haemorrhage are low. This suggests that real-time analysis of clinical data with targeted interventions can reduce morbidity in LAM. These measures could be applied as quality standards to compare the emerging LAM clinical networks worldwide.
