Extracellular Vesicles as Potential Biomarkers and Therapeutic Target in Gaucher Disease

This is an observational study intended to generate preliminary data to understand how lysosomal dysfunction can affect the biogenesis of extracellular vesicles, its content and function. The primary objective of the proposed project is to decipher how extracellular vesicle (EV) biogenesis and its role in intercellular communication can be impaired as a consequence of defects in lysosomal function. Collectively these defects in EV biogenesis and function can contribute to the neuroinflammation observed in lysosomal storage diseases. Since EVs can cross the blood-brain barrier, their characterization may be valuable in identifying novel biomarkers. In the presence of a GBA1 mutation, the decrease in GCase activity will lower overall lysosome function and increase the secretion of EVs. Further, there will be differences in EV size, its cargo including lipids, RNA and proteins and their aggregates. In comparison to healthy controls, EVs isolated from patients with Gaucher disease (GD) and GBA1 carriers is hypothesized to show significant differences in terms of its characteristics and content, which can contribute to our understanding of the link between lysosomes and neurological disease.

GammaGA: Prevalence of Acid Sphingomyelinase Deficiency Disease (ASMD) and Gaucher Disease in Patients With Monoclonal Gammopathies and/or Multiple Myeloma

The study of splenomegaly, and the follow-up of splenectomized patients, is one of the causes of referral of these patients to pediatric gastroenterology and oncohematology clinics, and adult internal medicine and hematology. The study and management of splenomegaly is well described among the different medical specialties to which these patients arrive. After the application of the different algorithms and the different studies that are carried out, these splenomegaly are identified as being of hepatic, infectious, inflammatory, congestive, hematological origin and primary causes. Despite these studies of splenomegaly, approximately 10-15% of these patients still remain undiagnosed. Several studies have suggested that there is an increased frequency of MGUS (monoclonal gammopathy of undetermined significance) and/or multiple myeloma (MM) among Gaucher patients. Regarding ASMD (Acid Sphingomyelinase Deficiency), few studies have been published but it seems the 21% of patient with ASMD has MGUS and 15% ASMD patients have MGUS. Moreover, patients with MGUS and Gaucher disease (GD) are at increased risk of developing MM. The objective of the present study is to increase the diagnostic sensitivity of these unknown splenomegalys, or unknown splenomegaly patients with MGUS or multiple myeoloma who remain in consultations, using the usual diagnostic clinical procedures of unknown splenomegaly and unknown splenectomy patients, where we include the extraction of a blood sample for dry drop test (DBS), where the determination of the enzymatic/genetic activity will be carried out for Gaucher disease (GD) and acid sphingomyelinase deficiency (ASMD) , analysis of LisoGl1 and LisoSM.
