Clinical Trial Summary

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. It has been described that 0.3% of hospital admissions is for this reason. 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. The objective of the present study is to increase the diagnostic sensitivity of these unknown splenomegalys, or unknown splenomegaly patients who remain in consultations, using the usual diagnostic clinical procedures of unknown splenomegaly and unknown splenectomy patients, where the investigators 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.
