Abstract
Objectives
To determine the effectiveness of enzyme replacement therapies (ERT) for children with Gaucher disease (GD).
Design
A longitudinal cohort study including prospective and retrospective clinical data. Age- and gender-adjusted treatment effects were estimated using generalised linear mixed models. Children on treatment contributed data before and during treatment. Children not on treatment contributed natural history data.
Participants
Consenting children (N = 25, aged 1.1 to 15.6 years) with a diagnosis of GD (14 with GD1 and 11 with GD3) who attended a specialist treatment centre in England. At recruitment, 24 patients were receiving ERT (mean treatment duration, 5.57 years; range 0-13.7 years).
Outcome measures
Clinical outcomes chosen to reflect disease progression, included platelet count; haemoglobin and absence/presence of bone pain.
Results
Duration of ERT was associated with statistically significant improvements in platelet count (p < 0.001), haemoglobin (p < 0.001), and reported bone pain (p = 0.02). The magnitude of effect on haematological parameters was greater in children with GD3 than in those with GD1.
Conclusions
These data provide further evidence of the long-term effectiveness of ERT in children with GD.
