Abstract

Although alglucerase therapy has become the treatment of choice for symptomatic patients with Gaucher's disease, the low-dose/high-frequency regimen introduced as a means to reduce the high cost of treatment has raised major controversy. We evaluated the efficacy and safety of low-dose alglucerase in 29 patients with Gaucher's disease who completed 6 to 28 months of therapy. All received intravenous alglucerase at a monthly dose of 30 units/kg, given usually in equal doses 3 times a week. All patients responded well to treatment. The hematological improvement and the reduction in organomegaly were satisfactory. No correlation was found between age, sex, genotype, previous splenectomy, or severity score index and the response to treatment. Patients with a greater degree of hepatomegaly tended to have a more pronounced decrease in liver size, although this reduction did not reach statistical significance. We confirmed that a low-dose/high-frequency regimen of alglucerase was as effective as a high-dose/low-frequency protocol in the treatment of Gaucher's disease, even in the severely ill. Whenever cost is an issue, we recommend using this low-dose regimen.
