title: Gaucher's disease and pregnancy.
abstract: Gaucher's disease is an autosomal recessive lysosomal storage disease, resulting from a deficiency of the enzyme glucocerebrosidase, which is required for the lysosomal degradation of glycolipids. The clinical manifestations of the disease show a large heterogeneity, including hepatosplenomegaly, "bone crisis" and fracture, anemia, thrombocytopenia and, in the rarest types II and III, neurological decompensation. Type I, the most common form, usually presents with less severe symptoms and at a more advanced age. More than 30 mutations within the glucocerebrosidase gene have been recognized, and certain mutations seem to be related with a particular phenotype expression of the disease. Modern diagnosis of Gaucher's disease is performed by either determining the enzyme activity in peripheral blood leukocytes or through DNA-based analysis. Pregnancy concurrent with Gaucher's disease has several risks, including an increased severity of anemia and thrombocytopenia that can potentiate postpartum bleeding, and increased risk of infection and possibly an increased spontaneous abortion rate. Nevertheless, the majority of these pregnancies seem to proceed to term without significant complications. The effects that pregnancy might have on the course of the disease are still unresolved. Enzyme replacement therapy with alglucerase is the treatment of choice for patients with Gaucher's disease, but it is yet to be shown whether alglucerase reduces the risk of these complications during pregnancy and whether its use has any adverse effect on fetal development. We present an extensive review of the current literature regarding Gaucher's disease with special emphasis on pregnancies coexistent with this disease and, an analysis of the genetics, relevant prenatal diagnostic issues, and current treatment modalities.
