ABSTRACT
The data on occurrence and pathogenetic mechanisms of glucosylceramide lipidosis (Gaucher disease), which is based on the hereditary deficiency of glucocerebrosidase activity -the enzyme involved in the processing of cellular metabolism products, is presented. Clinical and morphological manifestations of the disease, therapeutic tactics and prognosis are defined. A typical clinical case of Gaucher disease type 1 in two adult patients was analyzed. It is shown that timely diagnosis of Gaucher disease allows the prescription of adequate treatment by means of enzyme replacement therapy with cerezyme drug. That is why the correct and timely diagnosis of the disease can prolongate patient's life for many years. In this case, the patient should be under the care of doctors (pediatricians, general physicians, hematologists). Continued treatment of Gaucher disease with cerezyme stabilizes the pathological process completely, decreases significant changes in bones and parenchymal organs, improving patients' lives considerably. For that reason, the sooner the adequate therapy is started, the more effective the results will be.
