Brief Summary
Congenital sucrose-isomaltase deficiency (CSID) is a rare, genetic disease in which mutations in the sucrose-isomaltase (SI) gene cause digestion problems of sucrose resulting in diarrhea and abdominal pain. Children with chronic, idiopathic diarrhea or abdominal pain will have their sucrose-isomaltase gene assessed for a panel of known CSID mutations to determine the prevalence of these mutations in an enriched population and also determine functional deficiency using a breath test.

Outcome Measures
Primary Outcomes (1)
Prevalence of CSID Genetic Variants

1 year
Study Arms (2)
CSID Mutations
Individual has one or more known CSID mutations.
Control
Individual does not have any known CSID mutations.
Eligibility Criteria
18 years of age or younger experiencing chronic, idiopathic diarrhea or abdominal pain for at least 4 weeks.
You may qualify if:
- Must be 18 years of age or younger.
- A primary clinical diagnosis of chronic idiopathic diarrhea or chronic abdominal pain for at least 4 weeks.
- English or Spanish speaking subjects and parent(s)/guardian only.
- Parental consent from one parent/guardian and also subject assent when appropriate based on individual IRB requirements.
You may not qualify if:
- Any condition(s) or finding(s) that in the opinion of the principal investigator suggests an alternative diagnosis for his/her gastrointestinal symptoms.
- Abdominal pain primarily related to constipation.
- Suspected gastrointestinal infectious disease.
- No current use of sacrosidase (Sucraid® Oral Solution).
- Known gastrointestinal disease such as celiac disease.
- Prior consumption of an investigational medication within the last 4 weeks.
- Antibiotics in the last 2 weeks, and no history of viral gastroenteritis within that same period of time.
- Known Hepatitis B or C infection (positive HBsAg or HCV within 6 months of enrollment) or Subject-Pugh Class C liver disease of any cause, HIV infection, tuberculosis, Clostridia difficile co-infection, cancer or systemic infections.
- Severe neurologic impairment that would prevent them from reporting a history of abdominal pain.
- Receiving or received biologic therapies (including infliximab, adalimumab, natalizumab) within 3 months prior to or at enrollment.
- Present or past use of immune modulators therapy (e.g., azathioprine, 6MP, methotrexate).
- Planned or previous abdominal surgery (e.g., bowel resection).
- Subjects with severe, uncontrolled systemic diseases.
- Presence of clinical alarm signs, including hypotension, anemia requiring blood transfusions, altered mental status, or inability to tolerate food and/or fluids by mouth.
