Abstract

Aim: We report through the first Tunisian experience with enzyme replacement therapy, the goals and consensus recommendations for treatment and monitoring of paediatric non neuronopathic Gaucher disease.
Methods: Three children with Gaucher disease undergone enzyme replacement therapy with Cerezyme® for severe visceral and/or bone involvement. Visceral, hematologic, bone, and growth parameters were assessed initially and under treatment.
Results: Two children presented with severe visceral or hematologic picture. One patient had myocardiopathy and primitive portal hypertension and another was diagnosed with cirrhosis related to Gaucher disease. Recurrent avascular necrosis and osteoporosis have justified treatment in another child. All patients received an initial dose of 60U/Kg/2 weeks. We have seen a gradual disappearance of hepatosplenomegaly and a rapid normalisation of hematological parameters in two patients. A resistance to treatment indicated splenectomy in one patient. The improvement in bone mineral density was slower. A significant growth gain was observed in patients with growth retardation. No patient had developed Cerezyme antibodies.
Conclusion: Despite its effectiveness and safety demonstrated in these children, enzyme replacement therapy remains inaccessible because of its cost for emerging countries. The allogeneic bone marrow is an alternative therapy to encourage and to propose precociously for severe paediatric forms of Gaucher disease.
