An acute hypersensitivity reaction that occurred in Patient 5 on day 12 after HSPC gene therapy and concomitantly to a first administration of vancomycin was considered by the investigators to be probably related to HSPC gene therapy. The event resolved promptly after treatment with antihistamines, intravenous fluids, and glucocorticoids, with no sequelae.

CaseEnzymeAssay: The α-L-iduronidase enzyme activities in leucocytes from all patients in the study was measured using the artificial substrate 4-methylumbelliferyl α-L iduronide (Sigma). Values ranged from 0 to 2.47 nmol/h/mg protein (reference range: 28–92 nmol/h/mg protein) and did not correlate to the clinical phenotype.
