1/143. technetium-99m-HmPAO brain SPECT in infantile Gaucher's disease.

    The authors report serial technetium-99m hexamethylpropylene-amine-oxime brain single photon emission computed tomography (SPECT) findings in two infants with Gaucher's disease type 2. Detailed neurologic and laboratory examinations, including bone marrow biopsies and enzymatic assays, were described. Serial brain magnetic resonance imaging studies in one patient illustrated the progressive cerebral atrophy in the frontal and temporal lobes. The SPECT in both cases demonstrated positive findings of initial scattered hypoperfusion, with extending to hypoperfusion of the entire cerebrum after 4 months of clinical deterioration. These changes in the SPECT findings may reflect progressive degeneration of the cerebrum in Gaucher's disease type 2. brain SPECT may provide useful information on cerebral flow and metabolic distribution corresponding to the neurologic deficits of neuronopathic Gaucher's disease.

2/143. Massive splenomegaly and Epstein-Barr virus-associated infectious mononucleosis in a patient with gaucher disease.

    PURPOSE: gaucher disease should be considered in the differential diagnosis of a patient with Epstein-Barr virus (EBV) infection who has unexplained or disproportionate splenomegaly. patients AND methods: A previously asymptomatic adolescent with EBV-associated infectious mononucleosis and massive splenomegaly is described. He was found to have gaucher disease on bone marrow biopsy, which was performed to exclude a hematologic malignancy. The diagnosis was confirmed by assay of beta-glucosidase enzyme activity. RESULTS: Regression of splenomegaly and improving hematologic indices. CONCLUSION: patients with infectious mononucleosis and disproportionate organomegaly should be investigated to exclude a hematologic malignancy or an underlying storage disorder such as gaucher disease.

3/143. Gaucher's disease with valve calcification: possible role of Gaucher cells, bone matrix proteins and integrins.

    Gaucher's disease, an autosomal recessive storage disease, leads to deposition of glucocerebrosides in various organs, especially those of the reticuloendothelial system. The heart is not thought to be frequently involved and studies of patients with cardiac involvement have concentrated on myocardial involvement. Despite careful prior investigation Gaucher cells have never been detected in the valves of these patients. Pathological findings of a patient with Gaucher's disease, type IIIc, with prominent cardiac valvular involvement are reported and, for the first time, the presence of Gaucher cells in the valve tissue is documented. There is evidence that the pathogenesis of the valvular injury may be by way of a cell-mediated mechanism involving bone matrix proteins and integrins.

4/143. enzyme therapy in gaucher disease type 2: an autopsy case.

    A Japanese patient with gaucher disease type 2 was treated with enzyme therapy, alglucerase, from 7 to 22 months of age. Whereas hematologic parameters were normalized and hepatosplenomegaly was alleviated, no improvement in neurologic symptoms occurred, and the patient died of respiratory failure at age 22 months. Postmortem examination revealed massive intra-alveolar infiltration of Gaucher cells in lungs and in the central nervous system, i.e., the presence of Gaucher cells in the perivascular Virchow-Robins spaces in the cortex and deep white matter and extensive lamilar necrosis with reactive proliferation of blood vessels and macrophage infiltration of the cerebral cortex. It is suggested that enzyme therapy, with thus far recommended dose, does not prevent long-term respiratory and central nervous system involvement in severe varients of Gaucher disease.

5/143. Intracellular transport of acid beta-glucosidase and lysosome-associated membrane proteins is affected in Gaucher's disease (G202R mutation).

    Gaucher's disease (GD) is caused by an inherited deficiency of acid beta-glucosidase with storage of glucosylceramides in the lysosomes of macrophages. This study identifies a G202R mutation in the acid beta-glucosidase gene in an infant with severe neuronopathic (type 2) GD and only slightly reduced acid beta-glucosidase activity. Western blot analysis, pulse chase experiments, and the thin frozen section immunogold method were used to analyse the implications of this mutation on the pathogenesis, clinical heterogeneity and diagnostic evaluation of GD. The results show that acid beta-glucosidase persists in the patient's fibroblasts as a mannose-rich polypeptide in the endoplasmic reticulum and is not transported to the lysosomes. By contrast, high expression of the lysosome-associated membrane proteins LAMP-1 and LAMP-2, saposin C, and cathepsin d was observed in the patient's lysosomes. Immunogold labelling of the integral membrane proteins LAMP-1 and LAMP-2 increases significantly at the cell surface of kupffer cells and fibroblasts as well as at the apical membrane of hepatocytes. In addition, LAMP-1 and LAMP-2 associate with the bilayer of stored glucosylceramide. It is concluded that defective intracellular transport of mutant acid beta-glucosidase from the endoplasmic reticulum to lysosomes leads to a more severe clinical phenotype than the residual enzyme activity may indicate. Furthermore, the detection of LAMP in the tubular bundles of undigested glucosylceramides, as well as their increased concentration at the surfaces of the affected cells, suggests that these proteins play a role in the storage or removal of substrate in GD. Intracellular targeting of acid beta-glucosidase and LAMP contributes to the broad phenotypic heterogeneity of GD.

6/143. Hepatosplenomegalic lipidosis: what unless Gaucher? adult cholesteryl ester storage disease (CESD) with anemia, mesenteric lipodystrophy, increased plasma chitotriosidase activity and a homozygous lysosomal acid lipase -1 exon 8 splice junction mutation.

    A 36-year-old woman was admitted for hepatosplenomegaly and anemia. bone marrow cytology showed "sea-blue histiocytes", vacuolated macrophages and plasma cells. As primary liver disease, malignancy or hematologic disorders were excluded, and plasma chitotriosidase activity was increased 27-fold over control, the presence of a lysosomal storage disease was suspected. Biochemical analysis of skin fibroblasts revealed normal glucocerebrosidase and sphingomyelinase activity, but lipid analysis showed a more than 15-fold accumulation of cholesterol esters within the cells. The activity of lysosomal acid lipase (LAL) in fibroblast homogenates was decreased to 12% of control subjects. Mutational analysis of the patient's blood showed the homozygous G-->A mutation at position -1 of the exon 8 splice donor site (E8SJM-allele) known for adult cholesteryl ester storage disease (CESD); the polymorphic background was that of the complex haplotype -6Thr, 2Gly, 894 G-->A. Based on clinical, laboratory, cytological and and biochemical findings, CESD can clearly be separated from other more frequent inherited lysosomal storage diseases, e.g. atypical forms of gaucher disease.

7/143. immunohistochemistry applied to the study of bone marrow Gaucher's cells: a case report.

    Gaucher's disease is frequently associated with immunologic abnormalities, e.g. hypergammaglobulinemia, polyclonal gammopathy and benign monoclonal gammopathy. A patient with Gaucher's disease and a selective accumulation of IgM k in Gaucher's cells without serum monoclonal gammopathies is described. The selective accumulation is detected by immunohistochemistry analysis performed on cryostat bone marrow biopsies.

8/143. Systemic AL amyloidosis in gaucher disease. A case report and review of the literature.

    Chronic gaucher disease [GD] in association with systemic AL amyloidosis is extremely rare. We describe a 46-year-old Greek male with chronic GD confirmed by low glucocerebroside activity in fibroblasts and N370S/L444P mutations at the cerebrosidase gene, who also had systemic AL amyloidosis diagnosed by bone marrow diffuse plasmacytosis, serum monoclonal IgA-lambda, severe total proteinuria with monoclonal IgA-lambda, Bence-Jones-lambda and amyloid deposits in bone marrow, liver, spleen and kidney biopsy specimens. Treatment with melphalan and prednizolon has dramatically decreased both levels of serum M-IgA and proteinuria and also improved the clinical symptoms of amyloidosis. He died from restrictive cardiac disease 30 months after the diagnosis of amyloidosis. Previously reported cases of GD in association with AL amyloidosis are reviewed.

9/143. Type I gaucher disease: extraosseous extension of skeletal disease.

    OBJECTIVE: To investigate the frequency and morphology of extraosseous extension in patients with gaucher disease type I. DESIGN AND patients: MRI examinations of the lower extremities were analyzed in 70 patients with gaucher disease type I. Additionally, the thoracic spine and the midface were investigated on MRI in two patients. RESULTS: Four cases are presented in which patients with gaucher disease type I and severe skeletal involvement developed destruction or protrusion of the cortex with extraosseous extension into soft tissues. In one patient, Gaucher cell deposits destroyed the cortex of the mandible and extended into the masseter muscle. In the second patient, multiple paravertebral masses with localized destruction of the cortex were apparent in the thoracic spine. In the third and fourth patient, cortical destruction with extraosseous tissue extending into soft tissues was seen in the lower limbs. CONCLUSIONS: Extraosseous extension is a rare manifestation of Gaucher bone disease. While an increased risk of cancer, especially hematopoietic in origin, is known in patients with gaucher disease, these extraosseous benign manifestations that may mimic malignant processes should be considered in the differential diagnosis of extraosseous extension into soft tissues. A narrow neck of tissue was apparent in all cases connecting bone and extraosseous extensions.

10/143. Pseudo-Gaucher cells in myelodysplasia.

    A case of myelodysplastic syndrome is reported, in which the bone marrow contained many cells with the typical light microscopic morphology of Gaucher cells. In the absence of any evidence of inherited Gaucher's disease, these cells are considered to be pseudo-Gaucher cells, which have been described previously in association with other haematological diseases. This is the first report of their occurrence in myelodysplastic syndrome.
