Description

Pompe disease (also known as glycogen storage disease type II and acid maltase deficiency) is an autosomal recessive disorder caused by a deficiency of the lysosomal enzyme acid α-glucosidase (GAA). Prompt diagnosis and initiation of enzyme replacement therapy with recombinant human GAA (rhGAA) are critical for reducing mortality and disability. A key predictor of clinical response to replacement therapy is a patient's CRIM (cross-reactive immunological material to GAA) status, which is based on the presence or absence of endogenous GAA. Patients who are CRIM-positive produce detectable GAA and are typically immunologically tolerant of rhGAA, whereas approximately 20% of patients who are CRIM-negative develop high levels of antibodies against exogenous rhGAA, which eventually reduces the efficacy of therapy PMID: 24044919.
