NA: not available; 6-MWD: 6-minute walk distance; DLco: diffusing capacity of carbon monoxide, FEV1: forced expiratory volume in 1 second; FVC: forced vital capacity; Δ: variation of FVC and FEV1 before and after cladribine treatment; PaO2: pulmonary arterial tension in blood gases, WHO: World Health Organization.
Results were obtained within hours or days before the first course of cladribine therapy (“Pre”), then 1 month (up to 3 months) after the last cladribine dose (“Post”). Volumes are indicated after inhalation of short-acting bronchodilators.
