Abstrakt: Background: There have been few descriptions in the literature on long-term enzyme replacement therapy (ERT) in patients with advanced late-onset Pompe disease (LOPD).
Objectives: This study aimed to assess the efficacy and limitations of ERT in advanced LOPD patients.
Methods: We retrospectively reviewed the clinical courses of patients with advanced LOPD (two juvenile-onset and five adult-onset patients) who were treated with recombinant human alglucosidase alfa to examine improvements achieved with and limitations of ERT until their death or when switching to avalglucosidase alfa occurred.
Results: All patients were non-ambulant and ventilator dependent. The duration of follow-up ranged from 3.7 to 15.0 years (median 9.0 years). All patients reported improvements in their lives during the first two or three years of ERT. Vital capacity was clearly improved in patients with relatively spared respiratory function, although it deteriorated after respiratory complications such as pneumothorax. Pinch and grip power tended to be preserved during the treatment period. Muscle CT revealed progression of atrophy and fatty replacement predominantly in the proximal limb muscles without improvement after ERT. Four patients died due to aspergillosis, respiratory failure, ileus, and sudden death of unknown cause.
Conclusions: Our findings demonstrate that patients undergoing ERT show certain improvements, even in the advanced stage of Pompe disease. Respiratory complications are lethal even during ERT, and early diagnosis and induction of therapy are critical. Muscle wasting progressed more severely in the proximal limbs, even after ERT.
