Summary

Rational: Imiglucerase has been used to treat Gaucher disease since 1997 but data about its pharmacokinetics have been partial; investigators know that imiglucerase undergoes a quick clearance from plasma compartment following the infusion (1/2 life: 1-6 min, from tissue: \<24h), an observation apparently contradictory with usual infusion rhythm (one infusion every two weeks). Furthermore, by going by GD response, the rhythm of Infusion is sometimes diminished (for example, every 3 or 4 wks) without pharmacological rational ; In parallel, investigators demonstrated that monocytes represent a satisfactory surrogate of GD target cells and that enzyme activity into monocytes varies between individuals.

Our hypothesis is that enzyme activity into monocyte compartment could be different and could be related to GD response.

Primary purpose: to evaluate the pharmacokinetics of Imiglucerase activity into target cellular compartment depending on dose and frequency of infusions.

Secondary purposes : 1) to establish a possible relationship between the intra-monocytic activity of glucocerebrosidase and the clinical and biological activity of Gaucher disease and to define a possible threshold value of enzyme activity; 2) to establish a better correlation with known biomarkers of disease (routine markers and markers recently identified), which would better predict and / or monitor response to treatment ; 3) to compare the residual and natural rate of activity enzyme intra-monocytic for untreated patients (low severity disease).
