Plain-language 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.

* Unexplained splenomegaly, defined as a palpable spleen ≥ 1 cm below the costal margin or diagnosed by ultrasound, magnetic resonance imaging (MRI), or computed tomography (CT) of the spleen.
* Splenectomized patients without a diagnosis of the cause of unexplained splenomegaly.
* Patients who provide their consent to participate in the study.
EXCLUSION CRITERIA:
* Splenomegaly due to portal hypertension (documented by abdominal ultrasound or another instrumental test) caused by liver disease
* Malignant hematologic tumor \[documented by positive physical examination + blood smear or fine-needle aspiration (FNA) or bone marrow biopsy\]

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
