High-intensity exercise improves pulmonary function and exercise tolerance in a patient with TSC-LAM.

INTRODUCTION

While exercise has been shown to improve respiratory symptoms, exercise tolerance, and bone mineral density in many populations, no supervised exercise training interventions have been undertaken in patients with lymphangioleiomyo-matosis (LAM).

MATERIAL AND

METHODS

One patient with TSC-LAM (tuberous sclerosis complex lymphangioleiomyomatosis) participated in two weekly sessions (50-60 min) of supervised aerobic exercise at 80-85% heart rate max for one year. Treadmill ergometry (VO2peak), spirometry (FEV1, FVC, FEV1/FVC, peak flow), and bone mineral density testing were performed prior to every 3 months.

RESULTS

After one year of supervised aerobic exercise training we saw dramatic increases in the patient's VO2max (20%), FEV1 (9.5%), FEV1/FVC (9.1%) and peak flow (47%).

CONCLUSIONS

The results from this study indicate that supervised exercise training can improve exercise tolerance and pulmonary function in a patient with lymphangioleiomyomatosis. Further research is needed, including longitudinal studies with larger sample sizes, to determine long-term effects and consistency of these findings. Aerobic exercise may offer a viable alternative or com-pliment to pharmacological interventions in the treatment of lymphangioleiomyomatosis. We show that high-intensity exercise training can markedly and safely improve pulmonary function in a patient with TSC-LAM. While we did not record quality of life or mood states, our patient did report improved self-confidence as well as enhanced mood.
